It implements the server-side part of the Git network protocol used by .Xr git 1 and .Xr got 1 . .Pp .Nm is not an interactive shell. .Nm is intended to be configured as the login shell of Git repository user accounts on servers running .Xr gotd 8 . If users require a different login shell, .Nm can be installed in the command search path under the names .Cm git-receive-pack and .Cm git-upload-pack , or .Xr gitwrapper 1 can be used to select the appropriate command to run automatically. .Pp The users can then interact with .Xr gotd 8 over the network. When users invoke commands such as .Cm got send and .Cm got fetch on client machines, .Xr got 1 will connect to the server with .Xr ssh 1 . .Nm will facilitate communication between .Xr gotd 8 running on the server machine and the .Xr got 1 or .Xr git 1 program running on the client machine. .Pp Users running .Nm should not have access to Git repositories by means other than accessing the unix socket of .Xr gotd 8 via .Nm . .Pp The .Cm weblogin command provides user authentication for .Xr gotwebd 8 . .Nm will connect to .Xr gotwebd 8 and obtain a login URL which allows browsing private repositories the user has been granted read access to in .Xr gotwebd.conf 5 . If multiple servers are declared in .Xr gotwebd.conf 5 the .Ar hostname parameter is required and indicates the desired virtual host to use in the URL. If no .Ar hostname is specified and only one server is declared in .Xr gotwebd.conf 5 then the name of this server will be used in the URL. .Pp It is recommended to restrict .Xr ssh 1 features available to users of .Nm . See the .Sx EXAMPLES section for details. .Sh ENVIRONMENT .Bl -tag -width GOTD_UNIX_SOCKET .It Ev GOTD_UNIX_SOCKET Set the path to the unix socket which .Xr gotd 8 is listening on. If not specified, the default path .Pa /var/run/gotd.sock will be used. .El .Sh EXAMPLES .Xr sshd_config 5 directives such as the following are recommended to protect the server machine and any systems reachable from it, especially if anonymous users are allowed to connect: .Bd -literal -offset indent Match User developer DisableForwarding yes PermitTTY no .Ed .Pp It can be convenient to add all relevant users to a common group, such as .Dq developers , and then use this group as the Match criteria: .Bd -literal -offset indent Match Group developers DisableForwarding yes PermitTTY no .Ed .Pp Anonymous users can be given public read-only access by using a .Xr gotd.conf 5 access rule such as the following: .Bd -literal -offset indent repository "public" { path "/var/git/public.git" permit ro anonymous } .Ed .Pp The anonymous user account should have a publicly known password, or can be set up with an empty password in which case the user's .Xr vipw 8 entry would look similar to this example: .Bd -literal anonymous::1002:1002::0:0:Anonymous:/home/anonymous:/usr/local/bin/gotsh .Ed .Pp Use of an empty password must be explicitly allowed in .Xr sshd_config 5 : .Bd -literal -offset indent Match User anonymous PasswordAuthentication yes PermitEmptyPasswords yes DisableForwarding yes PermitTTY no .Ed .Pp Obtain a .Xr gotwebd 8 login URL for got.example.com: .Bd -literal -offset indent $ ssh got.example.com weblogin .Ed .Pp If the web server at got.example.com serves virtual hosts then two hostnames must be provided. One for .Xr ssh 1 to connect to, and another to identify the virtual host served by .Xr gotwebd 8 : .Bd -literal -offset indent $ ssh got.example.com weblogin got.example.com .Ed .Pp In practice both hostnames will often be the same, but this is not guaranteed. There is no reliable way determine the desired virtual host automatically. An .Xr ssh_config 5 entry like the following can save some typing: .Bd -literal -offset indent Host weblogin Hostname got.example.com RemoteCommand weblogin %h .Ed .Pp The following command is now equivalent to the above: .Bd -literal -offset indent $ ssh weblogin .Ed .Ed .Sh SEE ALSO .Xr gitwrapper 1 , .Xr got 1 , .Xr ssh 1 , .Xr gotd.conf 5 , .Xr gotwebd.conf 5 , .Xr sshd_config 5 , .Xr gotd 8 , .Xr gotwebd 8 .Sh AUTHORS .An Stefan Sperling Aq Mt stsp@openbsd.org got-portable-0.119/gotsh/Makefile.in0000664000175000017500000007227015066537207013022 # Makefile.in generated by automake 1.17 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2024 Free Software Foundation, Inc. # This Makefile.in is free software;

Got is ISC-licensed and was designed with pledge(2) and unveil(2) in mind. Got uses Git repositories to store versioned data. Git can be used for any functionality which has not yet been implemented in Got. It will always remain possible to work with both Got and Git on the same repository. A Got release tarball will install files under /usr/local by default. This default can be changed by passing PREFIX=/some/path to make. A build started in Got's Git repository will install files under ~/bin, which may have to be added to $PATH and be created first: $ mkdir ~/bin To compile the Got client tool suite on OpenBSD, run: $ make obj $ make $ make install This will install the following commands: got, the command line interface tog, an ncurses-based interactive Git repository browser several helper programs from the libexec directory man pages (only installed if building sources from a Got release tarball) Tests will pass only after 'make install' because they rely on installed binaries in $PATH. Any tests written as shell scripts also depend on git(1). Tests which use the got clone, fetch, and send commands will fail if 'ssh 127.0.0.1' does not succeed non-interactively. Tests for HTTP protocol support rely on the HTTP::Daemon Perl module. $ doas pkg_add git p5-http-daemon $ make regress To test with packed repositories, run: $ make regress GOT_TEST_PACK=1 To test with packed repositories using the ref-delta representation for deltified objects, run: $ make regress GOT_TEST_PACK=ref-delta To test with sha256 object IDs instead of sha1, run: $ make regress GOT_TEST_ALGO=sha256 The GOT_TEST_PACK and GOT_TEST_ALGO flags can be combined to test packed repositories with sha256 object IDs. Because got unveils the /tmp directory by default using the /tmp directory for test data can hide bugs. However, /tmp remains the default because there is no better alternative that works out of the box. In order to store test data in a directory other than /tmp, such as ~/got-test, run: $ mkdir ~/got-test $ make regress GOT_TEST_ROOT=~/got-test The tog automated test suite is also run with 'make regress'. Like Got, however, individual tests or the entire suite can be run: $ cd regress/tog $ make # run all tests $ ./log.sh # run log view tests Man page files in the Got source tree can be viewed with 'man -l': $ man -l got/got.1 $ man -l got/git-repository.5 $ man -l got/got-worktree.5 $ man -l tog/tog.1 EXAMPLES in got.1 contains a quick-start guide for OpenBSD developers. To compile the Got server tool suite on OpenBSD, run: $ make obj $ make server $ make server-install This will install the following commands: gotd, the repository server program gotctl, the server control utility gotsh, the login shell for users accessing the server via the network gitwrapper, like mailwrapper(8) but for git-upload-pack and git-receive-pack See the following manual page files for information about server setup: $ man -l gotd/gotd.8 $ man -l gotd/gotd.conf.5 $ man -l gotctl/gotctl.8 $ man -l gotsh/gotsh.1 $ man -l gitwrapper/gitwrapper.1 See regress/gotd/README for information about running the server test suite. Game of Trees Web Daemon (gotwebd) is a FastCGI program which displays repository data and is designed to work with httpd(8). To compile gotwebd on OpenBSD, run: $ make webd # make webd-install This will create the following files: the daemon program /usr/local/sbin/gotwebd css and image files in /var/www/htdocs/gotwebd the gotwebd init script in /etc/rc.d man pages (only installed if building sources from a Got release tarball) Documentation is available in manual pages: $ man -l gotwebd/gotwebd.8 $ man -l gotwebd/gotwebd.conf.5 The gotwebd test suite must be started as root in order to start and stop the gotwebd daemon. With the gotwebd binary installed, the test suite can be run from the top-level directory: $ doas make webd-regress The test suite switches to non-root users as appropriate. gotsysd(8) is a daemon which can be used to manage a gotd(8) server by committing a configuration file to the special "gotsys.git" repository. To compile gotsysd on OpenBSD, run: $ make sysd # make sysd-install This will create the following files: the daemon program /usr/local/sbin/gotsysd the control program /usr/local/sbin/gotsysctl man pages (only installed if building sources from a Got release tarball) Related documentation is available in manual pages: $ man -l gotsys/gotsys.conf.5 $ man -l gotsys/gotsys.1 $ man -l gotsysd/gotsysd.8 $ man -l gotsysd/gotsysd.conf.5 $ man -l gotsysctl/gotsysctl.8 See regress/gotsysd/README for information about the gotsysd test suite. Got can be built with profiling enabled to debug performance issues. Note that profiled builds cannot make use of pledge(2). Profiling should only be enabled for one program at a time. Otherwise, multiple programs will attempt to write to the 'gmon.out' file in the current working directory. For example, to compile got-read-pack with profiling enabled: $ cd libexec/got-read-pack $ make clean $ make PROFILE=1 $ make install Running any Got command which ends up using got-read-pack should now produce the file 'gmon.out' in the current working directory. The gprof2dot program can be used to generate a profile graph: $ doas pkg_add gprof2dot graphviz $ gprof ~/bin/got-read-pack gmon.out | gprof2dot | dot -T png > profile.png Guidelines for reporting problems: All problem/bug reports should include a reproduction recipe in form of a shell script which starts out with an empty repository and runs a series of Got and/or Git commands to trigger the problem, be it a crash or some other undesirable behaviour. The regress/cmdline directory contains plenty of example scripts. An ideal reproduction recipe is written as an xfail ("expected failure") regression test. For a real-world example of an xfail test, see commits 4866d0842a2b34812818685aaa31d3e0a966412d and 2b496619daecc1f25b1bc0c53e01685030dc2c74 in Got's history. Please take this request very seriously; Ask for help with writing your regression test before asking for your problem to be fixed. Time invested in writing a regression test saves time wasted on back-and-forth discussion about how the problem can be reproduced. A regression test will need to be written in any case to verify a fix and prevent the problem from resurfacing. It is also possible to write test cases in C. Various examples of this exist in the regress/ directory. Most such tests are unit tests; it is unlikely that a problem found during regular usage will require a test to be written in C. Please always try to find a way to trigger your problem via the command line interface before reporting a problem without a written test case included. If writing an automated test really turns out to be impossible, please explain in very clear terms how the problem can be reproduced. Mail problem reports to: gameoftrees@openbsd.org Guidelines for submitting patches: Mail patches to: gameoftrees@openbsd.org Pull requests via any Git hosting sites will likely be overlooked. Please keep the intended target audience in mind when contributing to Got.

It is reproduced here in a slightly edited form for convenience. A 65-character subset of US-ASCII is used, enabling 6 bits to be represented per printable character. (The extra 65th character, "=", is used to signify a special processing function.) The encoding process represents 24-bit groups of input bits as output strings of 4 encoded characters. Proceeding from left to right, a 24-bit input group is formed by concatenating 3 8-bit input groups. These 24 bits are then treated as 4 concatenated 6-bit groups, each of which is translated into a single digit in the base64 alphabet. Each 6-bit group is used as an index into an array of 64 printable characters. The character referenced by the index is placed in the output string. Table 1: The Base64 Alphabet Value Encoding Value Encoding Value Encoding Value Encoding 0 A 17 R 34 i 51 z 1 B 18 S 35 j 52 0 2 C 19 T 36 k 53 1 3 D 20 U 37 l 54 2 4 E 21 V 38 m 55 3 5 F 22 W 39 n 56 4 6 G 23 X 40 o 57 5 7 H 24 Y 41 p 58 6 8 I 25 Z 42 q 59 7 9 J 26 a 43 r 60 8 10 K 27 b 44 s 61 9 11 L 28 c 45 t 62 + 12 M 29 d 46 u 63 / 13 N 30 e 47 v 14 O 31 f 48 w (pad) = 15 P 32 g 49 x 16 Q 33 h 50 y Special processing is performed if fewer than 24 bits are available at the end of the data being encoded. A full encoding quantum is always completed at the end of a quantity. When fewer than 24 input bits are available in an input group, zero bits are added (on the right) to form an integral number of 6-bit groups. Padding at the end of the data is performed using the '=' character. Since all base64 input is an integral number of octets, only the ------------------------------------------------- following cases can arise: (1) the final quantum of encoding input is an integral multiple of 24 bits; here, the final unit of encoded output will be an integral multiple of 4 characters with no "=" padding, (2) the final quantum of encoding input is exactly 8 bits; here, the final unit of encoded output will be two characters followed by two "=" padding characters, or (3) the final quantum of encoding input is exactly 16 bits; here, the final unit of encoded output will be three characters followed by one "=" padding character. */ int b64_ntop(src, srclength, target, targsize) u_char const *src; size_t srclength; char *target; size_t targsize; { size_t datalength = 0; u_char input[3]; u_char output[4]; int i; while (2 < srclength) { input[0] = *src++; input[1] = *src++; input[2] = *src++; srclength -= 3; output[0] = input[0] >> 2; output[1] = ((input[0] & 0x03) << 4) + (input[1] >> 4); output[2] = ((input[1] & 0x0f) << 2) + (input[2] >> 6); output[3] = input[2] & 0x3f; if (datalength + 4 > targsize) return (-1); target[datalength++] = Base64[output[0]]; target[datalength++] = Base64[output[1]]; target[datalength++] = Base64[output[2]]; target[datalength++] = Base64[output[3]]; } /* Now we worry about padding. */ if (0 != srclength) { /* Get what's left. */ input[0] = input[1] = input[2] = '\0'; for (i = 0; i < srclength; i++) input[i] = *src++; output[0] = input[0] >> 2; output[1] = ((input[0] & 0x03) << 4) + (input[1] >> 4); output[2] = ((input[1] & 0x0f) << 2) + (input[2] >> 6); if (datalength + 4 > targsize) return (-1); target[datalength++] = Base64[output[0]]; target[datalength++] = Base64[output[1]]; if (srclength == 1) target[datalength++] = Pad64; else target[datalength++] = Base64[output[2]]; target[datalength++] = Pad64; } if (datalength >= targsize) return (-1); target[datalength] = '\0'; /* Returned value doesn't count \0. */ return (datalength); } /* skips all whitespace anywhere. converts characters, four at a time, starting at (or after) src from base - 64 numbers into three 8 bit bytes in the target area. it returns the number of data bytes stored at the target, or -1 on error. */ int b64_pton(src, target, targsize) char const *src; u_char *target; size_t targsize; { int tarindex, state, ch; u_char nextbyte; char *pos; state = 0; tarindex = 0; while ((ch = (unsigned char)*src++) != '\0') { if (isspace(ch)) /* Skip whitespace anywhere. */ continue; if (ch == Pad64) break; pos = strchr(Base64, ch); if (pos == 0) /* A non-base64 character. */ return (-1); switch (state) { case 0: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] = (pos - Base64) << 2; } state = 1; break; case 1: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] |= (pos - Base64) >> 4; nextbyte = ((pos - Base64) & 0x0f) << 4; if (tarindex + 1 < targsize) target[tarindex+1] = nextbyte; else if (nextbyte) return (-1); } tarindex++; state = 2; break; case 2: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] |= (pos - Base64) >> 2; nextbyte = ((pos - Base64) & 0x03) << 6; if (tarindex + 1 < targsize) target[tarindex+1] = nextbyte; else if (nextbyte) return (-1); } tarindex++; state = 3; break; case 3: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] |= (pos - Base64); } tarindex++; state = 0; break; } } /* * We are done decoding Base-64 chars.

The work tree's meta data is stored in the .Pa .got directory. A work tree is created with .Cm got checkout and is required to make changes to a Git repository with .Xr got 1 . .Pp A work tree stores the path to its Git repository, the name of a reference to the branch which files were checked out from, and the ID of a commit on this branch known as the .Em base commit . .Pp File meta-data is stored in a structured file called the .Em file index which tracks the status of file modifications, additions, and deletions, relative to the base commit in the repository. The file index contains a series of records, and each such record contains the following status information for a particular file: .Bl -tag -width Ds .It Copy of filesystem meta-data Timestamp, file size, and file ownership information from .Xr stat 2 . This is only used to detect file modifications and is never applied back to the filesystem. File permissions are not tracked, except for the executable bit. When versioned files are checked out into the work tree, the current .Xr umask 2 is heeded. .It Blob object ID The hash of the blob object which corresponds to the contents of this file in the repository. The hash is stored as binary data. The size of the hash depends on the hashing algorithm used in the repository. .It Commit object ID The hash of the commit object the file was checked out from. The hash is stored as binary data. This data is used to detect past incomplete update operations. Entries which do not match the work tree's base commit may still need to be updated to match file content stored in the base commit. .It Flags This field contains the length, according to .Xr strlen 3 , of path data which follows, and the following flags: .Bl -tag -width Ds .It STAGE Reflects the added, modified, or deleted staged state of a path staged with .Cm got stage . .It NOT_FLUSHED The entry was added to the file index in memory and does not exist in file index data read from disk. This happens to files which are added to the work tree while operations such as .Cm got checkout , .Cm got update , .Cm got cherrypick , .Cm got backout , .Cm got rebase , and .Cm got histedit are in progress. This flag is always cleared before the entry is written to disk. .It NO_BLOB The entry's on-disk file content in the work tree is not based on a blob in the repository. The blob object ID of this entry must be considered invalid. This happens when unversioned files are added with .Cm got add and when files are added to the work tree by operations such as .Cm got cherrypick , .Cm got backout , .Cm got rebase , and .Cm got histedit . .It NO_COMMIT The entry is not based on a commit in the repository. The commit object ID of this entry must be considered invalid. This happens when unversioned files are added with .Cm got add and when files are added to the work tree by operations such as .Cm got cherrypick , .Cm got backout , .Cm got rebase , and .Cm got histedit . .It NO_FILE_ON_DISK The entry has no corresponding on-disk file in the work tree. This happens when files are removed with .Cm got remove . .El .It Path data The path of the entry, relative to the work tree root. Path data is of variable length and NUL-padded to a multiple of 8 bytes. .It Staged blob object ID The hash of a blob object containing file content which has been staged for commit. The hash is stored as binary data. Only present if a file addition or modification has been staged with .Cm got stage . .El .Pp A corrupt or missing file index can be recreated on demand as follows: .Pp .Dl $ mv .got/file-index .got/file-index.bad .Dl $ got update # re-create .got/file-index .Dl $ find\ . -type f -exec touch {}\ + # update timestamp of all files .Dl $ got update # sync timestamps .Pp When the file index is modified, it is read into memory in its entirety, modified in place, and written to a temporary file. This temporary file is then moved on top of the old file index with .Xr rename 2 . This ensures that no other processes see an inconsistent file index which is in the process of being written. .Pp Work tree meta data must only be modified while the work tree's .Pa lock file has been exclusively locked with .Xr lockf 3 . .Pp Each work tree has a universal unique identifier. When a work tree is checked out or updated, this identifier is used to create a reference to the current base commit in the Git repository. The presence of this reference prevents the Git garbage collector and .Cm gotadmin cleanup from discarding the base commit and any objects it refers to. When a work tree is no longer needed, its reference can be deleted from the Git repository with .Cm got ref -d . .Sh FILES .Bl -tag -width path-prefix -compact .It Pa .got Meta-data directory where all files listed below reside. .It Pa base-commit hash digest hex-string representation of the current base commit. .It Pa file-index File status information. .It Pa format Work tree format number. .It Pa got.conf Configuration file for .Xr got 1 .

Conceptually, the repository's data model is a directed acyclic graph which contains four types of objects as nodes: .Bl -tag -width commits .It Blobs The content of tracked files is stored in objects of type .Em blob . .It Trees A .Em tree object points to any number of such blobs, and also to other trees in order to represent a hierarchy of files and directories. .It Commits A .Em commit object points to the root element of one tree, and thus records the state of this entire tree as a snapshot. Commit objects are chained together to form lines of version control history. Most commits have just one successor commit, but commits may be succeeded by an arbitrary number of subsequent commits so that diverging lines of version control history, known as .Em branches , can be represented. A commit which precedes another commit is referred to as that other commit's .Em parent commit . A commit with multiple parents unites disparate lines of history and is known as a .Em merge commit . .It Tags A .Em tag object associates a user-defined label with another object, which is typically a commit object. Tag objects also contain a tag message, as well as author and timestamp information. .El .Pp Each object is identified by an hash calculated over both the object's header and the data stored in the object. The hashing algorithm used is specified in the repository .Pa config file for newer repositories while older ones use SHA1 implicitly. .Sh OBJECT STORAGE Loose objects are stored as individual files beneath the directory .Pa objects , spread across 256 sub-directories named after the 256 possible hexadecimal values of the first byte of an object identifier. The name of the loose object file corresponds to the remaining hexadecimal byte values of the object's identifier. .Pp A loose object file begins with a header which specifies the type of object as an ASCII string, followed by an ASCII space character, followed by the object data's size encoded as an ASCII number string. The header is terminated by a .Sy NUL character, and the remainder of the file contains object data. Loose objects files are compressed with .Xr deflate 3 . .Pp Multiple objects can be bundled in a .Em pack file for better disk space efficiency and increased run-time performance. The pack file format introduces two additional types of objects: .Bl -tag -width Ds .It Offset Delta Objects This object is represented as a delta against another object in the same pack file. This other object is referred to by its offset in the pack file. .It Reference Delta Objects This object is represented as a delta against another object in the same pack file. The other object is referred to by its object identifier. .El .Pp Pack files are self-contained and may not refer to loose objects or objects stored in other pack files. Deltified objects may refer to other deltified objects as their delta base, forming chains of deltas. The ultimate base of a delta chain must be an object of the same type as the original object which is stored in deltified form. .Pp Each pack file is accompanied by a corresponding .Em pack index file, which lists the IDs and offsets of all objects contained in the pack file. .Sh REFERENCES A reference associates a name with an object ID. A prominent use of references is providing names to branches in the repository by pointing at commit objects which represent the current tip commit of a branch. Because references may point to arbitrary object IDs, their use is not limited to branches. .Pp The name is a non-empty UTF-8 string with the following disallowed characters: .Sq \ \& (space), \(a~ (tilde), \(a^ (caret), : (colon), ? (question mark), * (asterisk), [ (opening square bracket), \\ (backslash). The name may not be the string .Dq @ , may not begin with a / (slash), and may not begin or end with a \. (period). Additionally, the name may not contain the two-character sequences //, .. , and @{. .Pp Reference names may optionally have multiple components separated by the / (slash) character, forming a hierarchy of reference namespaces. Got reserves the .Pa refs/got/ reference namespace for internal use. .Pp A symbolic reference associates a name with the name of another reference. The most prominent example is the .Pa HEAD reference which points at the name of the repository's default branch reference. .Pp References are stored either as a plain file within the repository, typically under the .Pa refs/ directory, or in the .Pa packed-refs file which contains one reference definition per line. .Pp Any object which is not directly or indirectly reachable via a reference is subject to deletion by Git's garbage collector or .Cm gotadmin cleanup . .Sh FILES .Bl -tag -width packed-refs -compact .It Pa HEAD A reference to the current head commit of the Git work tree. In bare repositories, this file serves as a default reference. .It Pa ORIG_HEAD Reference to original head commit. Set by some Git operations. .It Pa FETCH_HEAD Reference to a branch tip commit most recently fetched from another repository. .It Pa branches/ Legacy directory used by the deprecated Gogito Git interface. .It Pa config Git configuration file. See .Xr git-config 1 . .It Pa description A human-readable description of the repository. .It Pa got.conf Configuration file for .Xr got 1 . See .Xr got.conf 5 . .It Pa hooks/ This directory contains hook scripts to run when certain events occur. .It Pa index The file index used by .Xr git 1 . This file is not used by .Xr got 1 , which uses the .Xr got-worktree 5 file index instead. .It Pa info Various configuration items. .It Pa logs/ Directory where reflogs are stored. .It Pa objects/ Loose and packed objects are stored in this directory. .It Pa packed-refs A file which stores references. Corresponding on-disk references take precedence over those stored here. .It Pa refs/ The default directory to store references in. .El .Pp A typical Git repository exposes a work tree which allows the user to make changes to versioned files and create new commits. When a Git work tree is present, the actual repository data is stored in a .Pa .git subfolder of the repository's root directory. A Git repository without a work tree is known as a .Dq bare repository. .Xr got 1 does not make use of Git's work tree and treats every repository as if it was bare. .Sh SEE ALSO .Xr got 1 , .Xr gotadmin 1 , .Xr deflate 3 , .Xr SHA1 3 , .Xr got-worktree 5 , .Xr got.conf 5 .Sh HISTORY The Git repository format was initially designed by Linus Torvalds in 2005 and has since been extended by various people involved in the development of the Git version control system. .Sh CAVEATS The particular set of disallowed characters in reference names is a consequence of design choices made for the command-line interface of .Xr git 1 . The same characters are disallowed by Got for compatibility purposes. Got additionally prevents users from creating reference names with a leading - (dash) character, because this is rarely intended and not considered useful. got-portable-0.119/got/got.10000664000175000017500000036654315066535721011305 .\" .\" Copyright (c) 2017 Martin Pieuchot .\" Copyright (c) 2018, 2019, 2020 Stefan Sperling .\" .\" Permission to use, copy, modify, and distribute this software for any .\" purpose with or without fee is hereby granted, provided that the above .\" copyright notice and this permission notice appear in all copies. .\" .\" THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES .\" WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF .\" MERCHANTABILITY AND FITNESS.

This repository format is described in .Xr git-repository 5 . .Pp .Nm is a .Dq distributed version control system because every copy of a repository is writeable. Modifications made to files can be synchronized between repositories at any time. .Pp Files managed by .Nm must be checked out from the repository for modification. Checked out files are stored in a .Em work tree which can be placed at an arbitrary directory in the filesystem hierarchy. The on-disk format of this work tree is described in .Xr got-worktree 5 . .Pp The .Nm utility provides global and command-specific options. Global options must precede the command name, and are as follows: .Bl -tag -width tenletters .It Fl h Display usage information and exit immediately. .It Fl V , -version Display program version and exit immediately. .El .Pp The .Nm utility only provides commands needed to perform version control tasks. Commands needed for repository maintenance tasks are provided by .Xr gotadmin 1 . Git repository server functionality is provided by .Xr gotd 8 . A repository interface for web browsers is provided by .Xr gotwebd 8 . An interactive repository interface for the terminal is provided by .Xr tog 1 . .Pp The commands for .Nm are as follows: .Bl -tag -width checkout .It Cm init Oo Fl A Ar hashing-algorithm Oc Oo Fl b Ar branch Oc Ar repository-path Create a new empty repository at the specified .Ar repository-path . .Pp After .Cm got init , the new repository must be populated before .Cm got checkout can be used. The .Cm got import command can be used to populate the new repository with data from a local directory. Alternatively, on a server running .Xr gotd 8 , the new repository can be made available to .Xr got 1 or .Xr git 1 clients by adding the repository to .Xr gotd.conf 5 and restarting .Xr gotd 8 . Clients may then clone the new repository from the server, populate the cloned repository, and then populate the new repository on the server via .Cm got send or .Cm git push . .Pp The options for .Cm got init are as follows: .Bl -tag -width Ds .It Fl A Ar hashing-algorithm Configure the repository's .Ar hashing-algorithm used for the computation of Git object IDs. Possible values are .Cm sha1 .Pq the default or .Cm sha256 . .It Fl b Ar branch Make the repository's HEAD reference point to the specified .Ar branch instead of the default branch .Dq main . .El .Pp The .Cm got init command is equivalent to .Cm gotadmin init . .Tg im .It Xo .Cm import .Op Fl b Ar branch .Op Fl I Ar pattern .Op Fl m Ar message .Op Fl r Ar repository-path .Ar directory .Xc .Dl Pq alias: Cm im Create an initial commit in a repository from the file hierarchy within the specified .Ar directory . The created commit will not have any parent commits, i.e. it will be a root commit. Also create a new reference which provides a branch name for the newly created commit. Show the path of each imported file to indicate progress. .Pp The .Cm got import command requires the .Ev GOT_AUTHOR environment variable to be set, unless an author has been configured in .Xr got.conf 5 or Git's .Dv user.name and .Dv user.email configuration settings can be obtained from the repository's .Pa .git/config file or from Git's global .Pa ~/.gitconfig configuration file. .Pp The options for .Cm got import are as follows: .Bl -tag -width Ds .It Fl b Ar branch Create the specified .Ar branch . If this option is not specified, a branch corresponding to the repository's HEAD reference will be used. Use of this option is required if the branch resolved via the repository's HEAD reference already exists. .It Fl I Ar pattern Ignore files or directories with a name which matches the specified .Ar pattern . This option may be specified multiple times to build a list of ignore patterns. The .Ar pattern follows the globbing rules documented in .Xr glob 7 . Ignore patterns which end with a slash, .Dq / , will only match directories. .It Fl m Ar message Use the specified log message when creating the new commit. Without the .Fl m option, .Cm got import opens a temporary file in an editor where a log message can be written. Quitting the editor without saving the file will abort the import operation. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. .El .Tg cl .It Xo .Cm clone .Op Fl almqv .Op Fl b Ar branch .Op Fl i Ar identity-file .Op Fl J Ar jumphost .Op Fl R Ar reference .Ar repository-URL .Op Ar directory .Xc .Dl Pq alias: Cm cl Clone a Git repository at the specified .Ar repository-URL into the specified .Ar directory . If no .Ar directory is specified, the directory name will be derived from the name of the cloned repository. .Cm got clone will refuse to run if the .Ar directory already exists. .Pp The .Ar repository-URL specifies a protocol scheme, a server hostname, an optional port number separated from the hostname by a colon, and a path to the repository on the server: .Lk scheme://hostname:port/path/to/repository .Pp The following protocol schemes are supported: .Bl -tag -width https .It git The Git protocol as implemented by the .Xr git-daemon 1 server. Use of this protocol is discouraged since it supports neither authentication nor encryption. .It ssh The Git protocol wrapped in an authenticated and encrypted .Xr ssh 1 tunnel. With this protocol the hostname may contain an embedded username for .Xr ssh 1 to use: .Mt user@hostname .It http The .Dq smart Git HTTP protocol. Not compatible with servers using the .Dq dumb Git HTTP protocol. .Pp The .Dq smart Git HTTP protocol is supported by .Cm got clone and .Cm got fetch , but not by .Cm got send . Sending from a repository cloned over HTTP will require use of a .Ic send block in .Xr got.conf 5 to ensure that the .Dq ssh:// protocol will be used by .Cm got send . .Pp Use of this protocol is discouraged since it supports neither authentication nor encryption. .It https The .Dq smart Git HTTP protocol wrapped in SSL/TLS. .El .Pp Objects in the cloned repository are stored in a pack file which is downloaded from the server. This pack file will then be indexed to facilitate access to the objects stored within. If any objects in the pack file are stored in deltified form, all deltas will be fully resolved in order to compute the ID of such objects. This can take some time. More details about the pack file format are documented in .Xr git-repository 5 . .Pp .Cm got clone creates a remote repository entry in the .Xr got.conf 5 and .Pa config files of the cloned repository to store the .Ar repository-url and any .Ar branch or .Ar reference arguments for future use by .Cm got fetch or .Xr git-fetch 1 . .Pp The options for .Cm got clone are as follows: .Bl -tag -width Ds .It Fl a Fetch all branches from the remote repository's .Dq refs/heads/ reference namespace and set .Cm fetch_all_branches in the cloned repository's .Xr got.conf 5 file for future use by .Cm got fetch . If this option is not specified, a branch resolved via the remote repository's HEAD reference will be fetched. Cannot be used together with the .Fl b option. .It Fl b Ar branch Fetch the specified .Ar branch from the remote repository's .Dq refs/heads/ reference namespace. This option may be specified multiple times to build a list of branches to fetch. If the branch corresponding to the remote repository's HEAD reference is not in this list, the cloned repository's HEAD reference will be set to the first branch which was fetched. If this option is not specified, a branch resolved via the remote repository's HEAD reference will be fetched. Cannot be used together with the .Fl a option. .It Fl i Ar identity-file Specify an .Ar identity-file , containing a private SSH key, to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl J Ar jumphost Specify a .Ar jumphost to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl l List branches and tags available for fetching from the remote repository and exit immediately. Cannot be used together with any of the other options except .Fl q and .Fl v . .It Fl m Create the cloned repository as a mirror of the original repository. This is useful if the cloned repository will not be used to store locally created commits. .Pp The repository's .Xr got.conf 5 and .Pa config files will be set up with the .Dq mirror option enabled, such that .Cm got fetch or .Xr git-fetch 1 will write incoming changes directly to branches in the .Dq refs/heads/ reference namespace, rather than to branches in the .Dq refs/remotes/ namespace. This avoids the usual requirement of having to run .Cm got rebase or .Cm got merge after .Cm got fetch in order to make incoming changes appear on branches in the .Dq refs/heads/ namespace. But maintaining custom changes in the cloned repository becomes difficult since such changes will be at risk of being discarded whenever incoming changes are fetched. .It Fl q Suppress progress reporting output. The same option will be passed to .Xr ssh 1 if applicable. .It Fl R Ar reference In addition to the branches and tags that will be fetched, fetch an arbitrary .Ar reference from the remote repository's .Dq refs/ namespace. This option may be specified multiple times to build a list of additional references to fetch. The specified .Ar reference may either be a path to a specific reference, or a reference namespace which will cause all references in this namespace to be fetched. .Pp Each reference will be mapped into the cloned repository's .Dq refs/remotes/ namespace, unless the .Fl m option is used to mirror references directly into the cloned repository's .Dq refs/ namespace. .Pp .Cm got clone will refuse to fetch references from the remote repository's .Dq refs/remotes/ or .Dq refs/got/ namespace. .It Fl v Verbose mode. Causes .Cm got clone to print debugging messages to standard error output. This option will be passed to .Xr ssh 1 if applicable. Multiple -v options increase the verbosity. The maximum is 3. .El .Tg fe .It Xo .Cm fetch .Op Fl adlqtvX .Op Fl b Ar branch .Op Fl i Ar identity-file .Op Fl J Ar jumphost .Op Fl R Ar reference .Op Fl r Ar repository-path .Op Ar remote-repository .Xc .Dl Pq alias: Cm fe Fetch new changes from a remote repository. If no .Ar remote-repository is specified, .Dq origin will be used. The remote repository's URL is obtained from the corresponding entry in .Xr got.conf 5 or Git's .Pa config file of the local repository, as created by .Cm got clone . .Pp By default, any branches configured in .Xr got.conf 5 for the .Ar remote-repository will be fetched. If .Cm got fetch is invoked in a work tree then this work tree's current branch will be fetched, too, provided it is present on the server. If no branches to fetch can be found in .Xr got.conf 5 or via a work tree, or said branches are not found on the server, a branch resolved via the remote repository's HEAD reference will be fetched. Likewise, if a HEAD reference for the .Ar remote-repository exists but its target no longer matches the remote HEAD, then the new target branch will be fetched. This default behaviour can be overridden with the .Fl a and .Fl b options. .Pp New changes will be stored in a separate pack file downloaded from the server. Over time, small pack files will accumulate as a result of repeatedly running .Ic got fetch . For best performance, multiple small pack files can be combined into a single larger pack file with .Ic gotadmin cleanup . The number of pack files in the repository is displayed by .Ic gotadmin info . .Pp By default, branch references in the .Dq refs/remotes/ reference namespace will be updated to point at the newly fetched commits. The .Cm got rebase or .Cm got merge command can then be used to make new changes visible on branches in the .Dq refs/heads/ namespace, merging incoming changes with the changes on those branches as necessary. .Pp If the repository was created as a mirror with .Cm got clone -m , then all branches in the .Dq refs/heads/ namespace will be updated directly to match the corresponding branches in the remote repository. If those branches contained local commits, these commits will no longer be reachable via a reference and will therefore be at risk of being discarded by Git's garbage collector or .Cm gotadmin cleanup . Maintaining custom changes in a mirror repository is therefore discouraged. .Pp In any case, references in the .Dq refs/tags/ namespace will always be fetched and mapped directly to local references in the same namespace. .Pp The options for .Cm got fetch are as follows: .Bl -tag -width Ds .It Fl a Fetch all branches from the remote repository's .Dq refs/heads/ reference namespace. This option can be enabled by default for specific repositories in .Xr got.conf 5 . Cannot be used together with the .Fl b option. .It Fl b Ar branch Fetch the specified .Ar branch from the remote repository's .Dq refs/heads/ reference namespace. This option may be specified multiple times to build a list of branches to fetch. Cannot be used together with the .Fl a option. .It Fl d Delete branches and tags from the local repository which are no longer present in the remote repository. Only references are deleted. Any commit, tree, tag, and blob objects belonging to deleted branches or tags remain in the repository and may be removed separately with Git's garbage collector or .Cm gotadmin cleanup . .It Fl i Ar identity-file Specify an .Ar identity-file , containing a private SSH key, to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl J Ar jumphost Specify a .Ar jumphost to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl l List branches and tags available for fetching from the remote repository and exit immediately. Cannot be used together with any of the other options except .Fl v , .Fl q , and .Fl r . .It Fl q Suppress progress reporting output. The same option will be passed to .Xr ssh 1 if applicable. .It Fl R Ar reference In addition to the branches and tags that will be fetched, fetch an arbitrary .Ar reference from the remote repository's .Dq refs/ namespace. This option may be specified multiple times to build a list of additional references to fetch. The specified .Ar reference may either be a path to a specific reference, or a reference namespace which will cause all references in this namespace to be fetched. .Pp Each reference will be mapped into the local repository's .Dq refs/remotes/ namespace, unless the local repository was created as a mirror with .Cm got clone -m in which case references will be mapped directly into the local repository's .Dq refs/ namespace. .Pp Once a reference has been fetched, a branch based on it can be created with .Cm got branch if needed. .Pp .Cm got fetch will refuse to fetch references from the remote repository's .Dq refs/remotes/ or .Dq refs/got/ namespace. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .It Fl t Allow existing references in the .Dq refs/tags namespace to be updated if they have changed on the server. If not specified, only new tag references will be created. .It Fl v Verbose mode. Causes .Cm got fetch to print debugging messages to standard error output. The same option will be passed to .Xr ssh 1 if applicable. Multiple -v options increase the verbosity. The maximum is 3. .It Fl X Delete all references which correspond to a particular .Ar remote-repository instead of fetching new changes. This can be useful when a remote repository is being removed from .Xr got.conf 5 . .Pp With .Fl X , the .Ar remote-repository argument is mandatory and no other options except .Fl r , .Fl v , and .Fl q are allowed. .Pp Only references are deleted. Any commit, tree, tag, and blob objects fetched from a remote repository will generally be stored in pack files and may be removed separately with .Ic gotadmin cleanup and Git's garbage collector. .El .Tg co .It Xo .Cm checkout .Op Fl \&Eq .Op Fl b Ar branch .Op Fl c Ar commit .Op Fl p Ar path-prefix .Ar repository-path .Op Ar work-tree-path .Xc .Dl Pq alias: Cm co Copy files from a repository into a new work tree.

If this option is not specified, a branch resolved via the repository's HEAD reference will be used. .It Fl c Ar commit Check out files from the specified .Ar commit on the selected branch. If this option is not specified, the most recent commit on the selected branch will be used. .Pp The expected .Ar commit argument is a commit ID, or a reference name or a keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the repository's HEAD reference, or, if the .Fl b option is used, the head of the checked-out .Ar branch . Keywords and reference names may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, .Sy :head:-2 denotes the work tree branch head's 2nd generation ancestor, and .Sy foo:-3 will denote the 3rd generation ancestor of the commit resolved by the .Qq foo reference. If an integer does not follow the .Qq :+ or .Qq :- modifier, a .Qq 1 is implicitly appended .Po e.g., .Sy :head:- is equivalent to .Sy :head:-1 .Pc . .Pp If the specified .Ar commit is not contained in the selected branch, a different branch which contains this commit must be specified with the .Fl b option. If no such branch is known, a new branch must be created for this commit with .Cm got branch before .Cm got checkout can be used. Checking out work trees with an unknown branch is intentionally not supported. .It Fl E Proceed with the checkout operation even if the directory at .Ar work-tree-path is not empty. Existing files will be left intact. .It Fl p Ar path-prefix Restrict the work tree to a subset of the repository's tree hierarchy.

Such files will be updated when .Cm got update is run again after merge conflicts have been resolved. If the conflicting changes are no longer needed, affected files can be reverted with .Cm got revert before running .Cm got update again. .Pp Show the status of each affected file, using the following status codes: .Bl -column YXZ description .It U Ta file was updated and contained no local changes .It G Ta file was updated and local changes were merged cleanly .It C Ta file was updated and conflicts occurred during merge .It D Ta file was deleted .It d Ta file's deletion was prevented by local modifications .It A Ta new file was added .It \(a~ Ta versioned file is obstructed by a non-regular file .It !

Ta changes destined for an unversioned file were not merged .El .Pp If no .Ar path is specified, update the entire work tree. Otherwise, restrict the update operation to files at or within the specified paths. Each path is required to exist in the update operation's target commit. Files in the work tree outside specified paths will remain unchanged and will retain their previously recorded base commit. Some .Nm commands may refuse to run while the work tree contains files from multiple base commits. The base commit of such a work tree can be made consistent by running .Cm got update across the entire work tree. Specifying a .Ar path is incompatible with the .Fl b option. .Pp .Cm got update cannot update paths with staged changes. If changes have been staged with .Cm got stage , these changes must first be committed with .Cm got commit or unstaged with .Cm got unstage . .Pp The options for .Cm got update are as follows: .Bl -tag -width Ds .It Fl b Ar branch Switch the work tree's branch reference to the specified .Ar branch before updating the work tree. This option requires that all paths in the work tree are updated. .Pp As usual, any local changes in the work tree will be preserved. This can be useful when switching to a newly created branch in order to commit existing local changes to this branch. .Pp Any local changes must be dealt with separately in order to obtain a work tree with pristine file contents corresponding exactly to the specified .Ar branch . Such changes could first be committed to a different branch with .Cm got commit , or could be discarded with .Cm got revert . .It Fl c Ar commit Update the work tree to the specified .Ar commit . If this option is not specified, the most recent commit on the work tree's branch will be used. .Pp The expected .Ar commit argument is a commit ID, or a reference name or a keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. Keywords and reference names may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent, respectively, by first parent traversal; for example, .Sy :head:-2 denotes the work tree branch head's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy foo:-3 will denote the 3rd generation ancestor of the commit resolved by the .Qq foo reference.

If invoked in a work tree, the .Ar path is interpreted relative to the current working directory, and the work tree's path prefix is implicitly prepended. Otherwise, the path is interpreted relative to the repository root. .Pp The options for .Cm got log are as follows: .Bl -tag -width Ds .It Fl b Display individual commits which were merged into the current branch from other branches. By default, .Cm got log shows the linear history of the current branch only. .It Fl C Ar number Set the number of context lines shown in diffs with .Fl p .

If this option is not specified, default to the work tree's current branch if invoked in a work tree, or to the repository's HEAD reference. .Pp The expected .Ar commit argument is a commit ID, or a reference name or a keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent, respectively, by first parent traversal; for example, .Sy :head:-2 denotes the HEAD reference's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy bar:+3 will denote the 3rd generation descendant of the commit resolved by the .Qq bar reference. A .Qq :+ or .Qq :- modifier without a trailing integer has an implicit .Qq 1 appended .Po e.g., .Sy :base:+ is equivalent to .Sy :base:+1 .Pc . .It Fl d Display diffstat of changes introduced in each commit. Cannot be used with the .Fl s option. Implies the .Fl P option (diffstat displays a list of changed paths). .It Fl l Ar N Limit history traversal to a given number of commits.

If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .It Fl S Ar search-pattern If specified, show only commits with a log message, author name, committer name, or commit ID matched by the extended regular expression .Ar search-pattern . Lines in committed patches will be matched if .Fl p is specified. File paths changed by a commit will be matched if .Fl P is specified. Regular expression syntax is documented in .Xr re_format 7 . .It Fl s Display a short one-line summary of each commit, instead of the default history format. Cannot be used together with the .Fl p or .Fl P option. .It Fl t Display commits in topological order. This option has no effect without the .Fl b option because a linear history is sorted in topological order by definition. Topological sorting is disabled by default because the present implementation requires that commit history is fully traversed before any output can be shown. .It Fl x Ar commit Stop traversing commit history immediately after the specified .Ar commit has been traversed. Like .Fl c , the expected .Ar commit argument is a commit ID, or a reference name or a keyword which will be resolved to a commit ID.

If one or more .Ar path arguments are specified, only show changes within the specified paths. .Pp If two arguments are provided, treat each argument as a reference, a tag name, or an object ID, and display differences between the corresponding objects. Both objects must be of the same type (blobs, trees, or commits). An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. If none of these interpretations produce a valid result or if the .Fl P option is used, and if .Cm got diff is running in a work tree, attempt to interpret the two arguments as paths. .Pp The options for .Cm got diff are as follows: .Bl -tag -width Ds .It Fl a Treat file contents as ASCII text even if binary data is detected. .It Fl C Ar number Set the number of context lines shown in the diff. By default, 3 lines of context are shown. .It Fl c Ar commit Show differences between commits in the repository. This option may be used up to two times. When used only once, show differences between the specified .Ar commit and its first parent commit. When used twice, show differences between the two specified commits. .Pp If the .Fl c option is used, all non-option arguments will be interpreted as paths. If one or more such .Ar path arguments are provided, only show differences for the specified paths. .Pp The expected .Ar commit argument is a commit ID, or a reference name or a keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent, respectively, by first parent traversal; for example, .Sy :head:-2 denotes the HEAD reference's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy baz:+8 will denote the 8th generation descendant of the commit resolved by the .Qq baz reference. If an integer does not follow the .Qq :+ or .Qq :- modifier, a .Qq 1 is implicitly appended .Po e.g., .Sy :head:- is equivalent to .Sy :head:-1 .Pc . .Pp Cannot be used together with the .Fl P option. .It Fl d Display diffstat of changes before the actual diff by annotating each file path or blob hash being diffed with the total number of lines added and removed. A summary line will display the total number of changes across all files. .It Fl P Interpret all arguments as paths only.

If this directory is a .Nm work tree, use the repository path associated with this work tree. .It Fl t Sort listed branches by modification time (most recently modified first) instead of sorting by lexicographical order. Branches in the .Dq refs/heads/ reference namespace are listed before branches in .Dq refs/remotes/ regardless. Use of this option requires the .Fl l option to be used as well. .El .It Xo .Cm tag .Op Fl lsVv .Op Fl c Ar commit .Op Fl m Ar message .Op Fl r Ar repository-path .Op Fl S Ar signer-id .Ar name .Xc Manage tags in a repository. .Pp Tags are managed via references which live in the .Dq refs/tags/ reference namespace. The .Cm got tag command operates on references in this namespace only. References in this namespace point at tag objects which contain a pointer to another object, a tag message, as well as author and timestamp information. .Pp Attempt to create a tag with the given .Ar name , and make this tag point at the given .Ar commit . If no commit is specified, default to the latest commit on the work tree's current branch if invoked in a work tree, and to a commit resolved via the repository's HEAD reference otherwise. .Pp The options for .Cm got tag are as follows: .Bl -tag -width Ds .It Fl c Ar commit Make the newly created tag reference point at the specified .Ar commit . The expected .Ar commit argument is a commit ID, or a reference or keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, .Sy :head:-2 denotes the work tree branch head's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy eggs:-3 will denote the 3rd generation ancestor of the commit resolved by the .Qq eggs reference. A .Qq :+ or .Qq :- modifier without a trailing integer has an implicit .Qq 1 appended .Po e.g., .Sy :base:+ is equivalent to .Sy :base:+1 .Pc . .It Fl l List all existing tags in the repository instead of creating a new tag. If a .Ar name argument is passed, show only the tag with the given .Ar name . .It Fl m Ar message Use the specified tag message when creating the new tag. Without the .Fl m option, .Cm got tag opens a temporary file in an editor where a tag message can be written. Quitting the editor without saving the file will abort the tag operation. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .It Fl S Ar signer-id While creating a new tag, sign this tag with the identity given in .Ar signer-id . .Pp For SSH-based signatures, .Ar signer-id is the path to a file which may refer to either a private SSH key, or a public SSH key with the private half available via .Xr ssh-agent 1 . .Cm got tag will sign the tag object by invoking .Xr ssh-keygen 1 with the .Fl Y Cm sign command, using the signature namespace .Dq git for compatibility with .Xr git 1 . .It Fl s Display a short one-line summary of each tag, instead of the default history format. Can only be used with the .Fl l option. .It Fl V Verify tag object signatures. If a .Ar name is specified, show and verify the tag object with the provided name. Otherwise, list all tag objects and verify signatures where present. .Pp .Cm got tag verifies SSH-based signatures by invoking .Xr ssh-keygen 1 with the options .Fl Y Cm verify Fl f Ar allowed_signers . A path to the .Ar allowed_signers file must be set in .Xr got.conf 5 , otherwise verification is impossible. .It Fl v Verbose mode. During SSH signature creation and verification this option will be passed to .Xr ssh-keygen 1 . Multiple -v options increase the verbosity. The maximum is 3. .El .Pp By design, the .Cm got tag command will not delete tags or change existing tags. If a tag must be deleted, the .Cm got ref command may be used to delete a tag's reference. This should only be done if the tag has not already been copied to another repository. .It Xo .Cm add .Op Fl IR .Ar path ... .Xc Schedule unversioned files in a work tree for addition to the repository in the next commit. By default, files which match an ignore pattern will not be added. See .Sx Ignore Patterns . .Pp If a .Ar path mentioned in the command line is not an unversioned file then .Cm got add may raise an error. To avoid unnecessary errors from paths picked up by file globbing patterns in the shell, paths in the argument list will be silently ignored if they are not reported by .Cm got status at all, or if they are reported with one of the following status codes and do not have changes staged via .Cm got stage : .Bl -column YXZ description .It M Ta modified file .It A Ta file scheduled for addition in next commit .It C Ta modified or added file which contains merge conflicts .It m Ta modified file modes (executable bit only) .El .Pp The options for .Cm got add are as follows: .Bl -tag -width Ds .It Fl I Add files even if they match an ignore pattern. See .Xs Ignore Patterns . .It Fl R Permit recursion into directories. If this option is not specified, .Cm got add will refuse to run if a specified .Ar path is a directory. .El .Tg rm .It Xo .Cm remove .Op Fl fkR .Op Fl s Ar status-codes .Ar path ... .Xc .Dl Pq alias: Cm rm Remove versioned files from a work tree and schedule them for deletion from the repository in the next commit. .Pp The options for .Cm got remove are as follows: .Bl -tag -width Ds .It Fl f Perform the operation even if a file contains local modifications, and do not raise an error if a specified .Ar path does not exist on disk. .It Fl k Keep affected files on disk. .It Fl R Permit recursion into directories. If this option is not specified, .Cm got remove will refuse to run if a specified .Ar path is a directory. .It Fl s Ar status-codes Only delete files with a modification status matching one of the single-character status codes contained in the .Ar status-codes argument. The following status codes may be specified: .Bl -column YXZ description .It M Ta modified file (this implies the .Fl f option) .It ! Ta versioned file expected on disk but missing .El .El .Tg pa .It Xo .Cm patch .Op Fl nR .Op Fl c Ar commit .Op Fl p Ar strip-count .Op Ar patchfile .Xc .Dl Pq alias: Cm pa Apply changes from .Ar patchfile to files in a work tree. Files added or removed by a patch will be scheduled for addition or removal in the work tree. .Pp The patch must be in the unified diff format as produced by .Cm got diff , .Xr git-diff 1 , or by .Xr diff 1 and .Xr cvs 1 diff when invoked with their .Fl u options. If no .Ar patchfile argument is provided, read unified diff data from standard input instead. .Pp If the .Ar patchfile contains multiple patches, then attempt to apply each of them in sequence. .Pp Show the status of each affected file, using the following status codes: .Bl -column XYZ description .It M Ta file was modified .It G Ta file was merged using a merge-base found in the repository .It C Ta file was merged and conflicts occurred during merge .It D Ta file was deleted .It A Ta file was added .It # Ta failed to patch the file .El .Pp If a change does not match at its exact line number, attempt to apply it somewhere else in the file if a good spot can be found. Otherwise, the patch will fail to apply. .Pp .Nm .Cm patch will refuse to apply a patch if certain preconditions are not met. Files to be deleted must already be under version control, and must not have been scheduled for deletion already. Files to be added must not yet be under version control and must not already be present on disk. Files to be modified must already be under version control and may not contain conflict markers. .Pp If an error occurs, the .Cm patch operation will be aborted. Any changes made to the work tree up to this point will be left behind. Such changes can be viewed with .Cm got diff and can be reverted with .Cm got revert if needed. .Pp The options for .Cm got patch are as follows: .Bl -tag -width Ds .It Fl c Ar commit Attempt to locate files within the specified .Ar commit for use as a merge-base for 3-way merges. .Pp If the .Fl c option is not used then .Cm got patch will attempt to locate merge-bases via object IDs found in .Ar patchfile meta-data, such as produced by .Cm got diff or .Xr git-diff 1 . Use of the .Fl c option is only recommended in the absence of such meta-data. .Pp Ideally, the specified .Ar commit should contain versions of files which the changes contained in the .Ar patchfile were based on. Files will be located by path, relative to the repository root. If the .Fl p option is used then leading path components will be stripped before paths are looked up in the repository. .Pp In case no merge-base is available for a file, changes will be applied without doing a 3-way merge. Changes which do not apply cleanly may then be rejected entirely, rather than producing merge conflicts in the patched target file. .Pp The expected .Ar commit argument is a commit ID, or a reference name or a keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. Keywords and references may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, .Sy :head:-2 denotes the work tree branch head's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy flan:+3 will denote the 3rd generation descendant of the commit resolved by the .Qq flan reference. A .Qq :+ or .Qq :- modifier without a trailing integer has an implicit .Qq 1 appended .Po e.g., .Sy :base:+ is equivalent to .Sy :base:+1 .Pc . .It Fl n Do not make any modifications to the work tree. This can be used to check whether a patch would apply without issues. If the .Ar patchfile contains diffs that affect the same file multiple times, the results displayed may be incorrect. .It Fl p Ar strip-count Specify the number of leading path components to strip from paths parsed from .Ar patchfile . If the .Fl p option is not used, .Sq a/ and .Sq b/ path prefixes generated by .Xr git-diff 1 will be recognized and stripped automatically. .It Fl R Reverse the patch before applying it. .El .Tg rv .It Xo .Cm revert .Op Fl pR .Op Fl F Ar response-script .Ar path ... .Xc .Dl Pq alias: Cm rv Revert any local changes in files at the specified paths in a work tree. File contents will be overwritten with those contained in the work tree's base commit. There is no way to bring discarded changes back after .Cm got revert ! .Pp If a file was added with .Cm got add , it will become an unversioned file again. If a file was deleted with .Cm got remove , it will be restored. .Pp The options for .Cm got revert are as follows: .Bl -tag -width Ds .It Fl F Ar response-script With the .Fl p option, read .Dq y , .Dq n , and .Dq q responses line-by-line from the specified .Ar response-script file instead of prompting interactively. .It Fl p Instead of reverting all changes in files, interactively select or reject changes to revert based on .Dq y (revert change), .Dq n (keep change), and .Dq q (quit reverting this file) responses. If a file is in modified status, individual patches derived from the modified file content can be reverted. Files in added or deleted status may only be reverted in their entirety. .It Fl R Permit recursion into directories. If this option is not specified, .Cm got revert will refuse to run if a specified .Ar path is a directory. .El .Tg ci .It Xo .Cm commit .Op Fl CNnS .Op Fl A Ar author .Op Fl F Ar path .Op Fl m Ar message .Op Ar path ... .Xc .Dl Pq alias: Cm ci Create a new commit in the repository from changes in a work tree and use this commit as the new base commit for the work tree. If no .Ar path is specified, commit all changes in the work tree. Otherwise, commit changes at or within the specified paths. .Pp If changes have been explicitly staged for commit with .Cm got stage , only commit staged changes and reject any specified paths which have not been staged. .Pp .Cm got commit opens a temporary file in an editor where a log message can be written unless the .Fl m option is used or the .Fl F and .Fl N options are used together. Quitting the editor without saving the file will abort the commit operation. .Pp Show the status of each affected file, using the following status codes: .Bl -column YXZ description .It M Ta modified file .It D Ta file was deleted .It A Ta new file was added .It m Ta modified file modes (executable bit only) .El .Pp Files which are not part of the new commit will retain their previously recorded base commit. Some .Nm commands may refuse to run while the work tree contains files from multiple base commits. The base commit of such a work tree can be made consistent by running .Cm got update across the entire work tree. .Pp The .Cm got commit command requires the .Ev GOT_AUTHOR environment variable to be set, unless an author has been configured in .Xr got.conf 5 or Git's .Dv user.name and .Dv user.email configuration settings can be obtained from the repository's .Pa .git/config file or from Git's global .Pa ~/.gitconfig configuration file. .Pp The options for .Cm got commit are as follows: .Bl -tag -width Ds .It Fl A Ar author Set author information in the newly created commit to .Ar author . This is useful when committing changes on behalf of someone else. The .Ar author argument must use the same format as the .Ev GOT_AUTHOR environment variable. .Pp In addition to storing author information, the newly created commit object will retain .Dq committer information which is obtained, as usual, from the .Ev GOT_AUTHOR environment variable, or .Xr got.conf 5 , or Git configuration settings. .It Fl C Allow committing files in conflicted status. .Pp Committing files with conflict markers should generally be avoided. Cases where conflict markers must be stored in the repository for some legitimate reason should be very rare. There are usually ways to avoid storing conflict markers verbatim by applying appropriate programming tricks. .It Fl F Ar path Use the prepared log message stored in the file found at .Ar path when creating the new commit. .Cm got commit opens a temporary file in an editor where the prepared log message can be reviewed and edited further if needed. Cannot be used together with the .Fl m option. .It Fl m Ar message Use the specified log message when creating the new commit. Cannot be used together with the .Fl F option. .It Fl N This option prevents .Cm got commit from opening the commit message in an editor. It has no effect unless it is used together with the .Fl F option and is intended for non-interactive use such as scripting. .It Fl n This option prevents .Cm got commit from generating a diff of the to-be-committed changes in a temporary file which can be viewed while editing a commit message. .It Fl S Allow the addition of symbolic links which point outside of the path space that is under version control. By default, .Cm got commit will reject such symbolic links due to safety concerns. As a precaution, .Nm may decide to represent such a symbolic link as a regular file which contains the link's target path, rather than creating an actual symbolic link which points outside of the work tree. Use of this option is discouraged because external mechanisms such as .Dq make obj are better suited for managing symbolic links to paths not under version control. .El .Pp .Cm got commit will refuse to run if certain preconditions are not met. If the work tree's current branch is not in the .Dq refs/heads/ reference namespace, new commits may not be created on this branch. Local changes may only be committed if they are based on file content found in the most recent commit on the work tree's branch. If a path is found to be out of date, .Cm got update must be used first in order to merge local changes with changes made in the repository. .Tg se .It Xo .Cm send .Op Fl afqTv .Op Fl b Ar branch .Op Fl d Ar branch .Op Fl i Ar identity-file .Op Fl J Ar jumphost .Op Fl r Ar repository-path .Op Fl t Ar tag .Op Ar remote-repository .Xc .Dl Pq alias: Cm se Send new changes to a remote repository. If no .Ar remote-repository is specified, .Dq origin will be used. The remote repository's URL is obtained from the corresponding entry in .Xr got.conf 5 or Git's .Pa config file of the local repository, as created by .Cm got clone . .Pp All objects corresponding to new changes will be written to a temporary pack file which is then uploaded to the server. Upon success, references in the .Dq refs/remotes/ reference namespace of the local repository will be updated to point at the commits which have been sent. .Pp By default, changes will only be sent if they are based on up-to-date copies of relevant branches in the remote repository. If any changes to be sent are based on out-of-date copies or would otherwise break linear history of existing branches, new changes must be fetched from the server with .Cm got fetch and local branches must be rebased with .Cm got rebase before .Cm got send can succeed. The .Fl f option can be used to make exceptions to these requirements. .Pp The options for .Cm got send are as follows: .Bl -tag -width Ds .It Fl a Send all branches from the local repository's .Dq refs/heads/ reference namespace. The .Fl a option is equivalent to listing all branches with multiple .Fl b options. Cannot be used together with the .Fl b option. .It Fl b Ar branch Send the specified .Ar branch from the local repository's .Dq refs/heads/ reference namespace. This option may be specified multiple times to build a list of branches to send. If this option is not specified, default to the work tree's current branch if invoked in a work tree, or to the repository's HEAD reference. Cannot be used together with the .Fl a option. .It Fl d Ar branch Delete the specified .Ar branch from the remote repository's .Dq refs/heads/ reference namespace. This option may be specified multiple times to build a list of branches to delete. .Pp Only references are deleted. Any commit, tree, tag, and blob objects belonging to deleted branches may become subject to deletion by Git's garbage collector running on the server. .Pp Requesting deletion of branches results in an error if the server does not support this feature or disallows the deletion of branches based on its configuration. .It Fl f Attempt to force the server to overwrite existing branches or tags in the remote repository, even when .Cm got fetch followed by .Cm got rebase or .Cm got merge would usually be required before changes can be sent. The server may reject forced requests regardless, depending on its configuration. .Pp Any commit, tree, tag, and blob objects belonging to overwritten branches or tags may become subject to deletion by Git's garbage collector running on the server. .Pp The .Dq refs/tags reference namespace is globally shared between all repositories. Use of the .Fl f option to overwrite tags is discouraged because it can lead to inconsistencies between the tags present in different repositories. In general, creating a new tag with a different name is recommended instead of overwriting an existing tag. .Pp Use of the .Fl f option is particularly discouraged if changes being sent are based on an out-of-date copy of a branch in the remote repository. Instead of using the .Fl f option, new changes should be fetched with .Cm got fetch and local branches should be rebased with .Cm got rebase or merged with .Cm got merge , followed by another attempt to send the changes. .Pp The .Fl f option should only be needed in situations where the remote repository's copy of a branch or tag is known to be out-of-date and is considered disposable. The risks of creating inconsistencies between different repositories should also be taken into account. .It Fl i Ar identity-file Specify an .Ar identity-file , containing a private SSH key, to use with SSH connections.

The .Fl T option is equivalent to listing all tags with multiple .Fl t options. Cannot be used together with the .Fl t option. .It Fl t Ar tag Send the specified .Ar tag from the local repository's .Dq refs/tags/ reference namespace, in addition to any branches that are being sent. The .Fl t option may be specified multiple times to build a list of tags to send. No tags will be sent if the .Fl t option is not used. .Pp Raise an error if the specified .Ar tag already exists in the remote repository, unless the .Fl f option is used to overwrite the server's copy of the tag. In general, creating a new tag with a different name is recommended instead of overwriting an existing tag. .Pp Cannot be used together with the .Fl T option. .It Fl v Verbose mode.

The .Ar branch must share common ancestry with the work tree's current branch. Rebasing begins with the first descendant commit of the youngest common ancestor commit shared by the specified .Ar branch and the work tree's current branch, and stops once the tip commit of the specified .Ar branch has been rebased. .Pp When .Cm got rebase is used as intended, the specified .Ar branch represents a local commit history and may already contain changes that are not yet visible in any other repositories. The work tree's current branch, which must be set with .Cm got update -b before starting the .Cm rebase operation, represents a branch from a remote repository which shares a common history with the specified .Ar branch but has progressed, and perhaps diverged, due to commits added to the remote repository. .Pp Rebased commits are accumulated on a temporary branch which the work tree will remain switched to throughout the entire rebase operation. Commits on this branch represent the same changes with the same log messages as their counterparts on the original .Ar branch , but with different commit IDs. Once rebasing has completed successfully, the temporary branch becomes the new version of the specified .Ar branch and the work tree is automatically switched to it. If author information is available via the .Ev GOT_AUTHOR environment variable, .Xr got.conf 5 or Git's .Dv user.name and .Dv user.email configuration settings, this author information will be used to identify the .Dq committer of rebased commits. .Pp Old commits in their pre-rebase state are automatically backed up in the .Dq refs/got/backup/rebase reference namespace. As long as these references are not removed older versions of rebased commits will remain in the repository and can be viewed with the .Cm got rebase -l command. Removal of these references makes objects which become unreachable via any reference subject to removal by Git's garbage collector or .Cm gotadmin cleanup . .Pp While rebasing commits, show the status of each affected file, using the following status codes: .Bl -column YXZ description .It G Ta file was merged .It C Ta file was merged and conflicts occurred during merge .It ! Ta changes destined for a missing file were not merged .It D Ta file was deleted .It d Ta file's deletion was prevented by local modifications .It A Ta new file was added .It \(a~ Ta changes destined for a non-regular file were not merged .It ?

If any files with destined changes are found to be missing or unversioned, or if files could not be deleted due to differences in deleted content, the rebase operation will be interrupted to prevent potentially incomplete changes from being committed to the repository without user intervention. The work tree may be modified as desired and the rebase operation can be continued once the changes present in the work tree are considered complete. Alternatively, the rebase operation may be aborted which will leave .Ar branch unmodified and the work tree switched back to its original branch. .Pp If a merge conflict is resolved in a way which renders the merged change into a no-op change, the corresponding commit will be elided when the rebase operation continues. .Pp .Cm got rebase will refuse to run if certain preconditions are not met.

The tip of this branch represents the upper bound (inclusive) of commits touched by the .Cm histedit operation. .Pp Furthermore, the work tree's base commit must be set with .Cm got update -c to a point in this branch's commit history where editing should begin. This commit represents the lower bound (non-inclusive) of commits touched by the .Cm histedit operation. .Pp Editing of commit history is controlled via a .Ar histedit script which can be written in an editor based on a template, passed on the command line, or generated with the .Fl d , .Fl e , .Fl f , or .Fl m options. Quitting the editor without saving the file will abort the histedit operation. .Pp The format of the histedit script is line-based. Each line in the script begins with a command name, followed by whitespace and an argument. For most commands, the expected argument is a commit ID. Any remaining text on the line is ignored. Lines which begin with the .Sq # character are ignored entirely. .Pp The available histedit script commands are as follows: .Bl -column YXZ pick-commit .It Cm pick Ar commit Ta Use the specified commit as it is. .It Cm edit Ar commit Ta Apply the changes from the specified commit, but then interrupt the histedit operation for amending, without creating a commit. While the histedit operation is interrupted arbitrary files may be edited, and commands which manipulate the work tree can be used freely. The .Cm got add and .Cm got remove commands can be used to add new files or remove existing ones. The .Cm got revert -p command can be used to eliminate arbitrary changes from files in the work tree. The .Cm got stage -p command may be used to prepare a subset of changes for inclusion in the next commit. Finally, the .Cm got commit command can be used to insert arbitrary commits into the edited history. Regular editing of history must eventually be resumed by running .Cm got histedit -c . .It Cm fold Ar commit Ta Combine the specified commit with the next commit listed further below that will be used. .It Cm drop Ar commit Ta Remove this commit from the edited history. .It Cm mesg Ar commit Ta Open an editor to create a new log message for this commit. .El .Pp Every commit in the history being edited must be mentioned in the script. Lines may be re-ordered to change the order of commits in the edited history. No commit may be listed more than once. .Pp Edited commits are accumulated on a temporary branch which the work tree will remain switched to throughout the entire histedit operation. Once history editing has completed successfully, the temporary branch becomes the new version of the work tree's branch and the work tree is automatically switched to it. .Pp Old commits in their pre-histedit state are automatically backed up in the .Dq refs/got/backup/histedit reference namespace. As long as these references are not removed older versions of edited commits will remain in the repository and can be viewed with the .Cm got histedit -l command. Removal of these references makes objects which become unreachable via any reference subject to removal by Git's garbage collector or .Cm gotadmin cleanup . .Pp While merging commits, show the status of each affected file, using the following status codes: .Bl -column YXZ description .It G Ta file was merged .It C Ta file was merged and conflicts occurred during merge .It !

While paths with staged changes exist, the .Cm got commit command will refuse to commit any paths which do not have staged changes. Local changes created on top of staged changes can only be committed if the path is staged again, or if the staged changes are committed first. The .Cm got status command will show both local changes and staged changes. The .Cm got diff command is able to display local changes relative to staged changes, and to display staged changes relative to the repository.

Otherwise, show all staged paths. .It Fl p Instead of staging the entire content of a changed file, interactively select or reject changes for staging based on .Dq y (stage change), .Dq n (reject change), and .Dq q (quit staging this file) responses. If a file is in modified status, individual patches derived from the modified file content can be staged. Files in added or deleted status may only be staged or rejected in their entirety. .It Fl S Allow staging of symbolic links which point outside of the path space that is under version control. By default, .Cm got stage will reject such symbolic links due to safety concerns. As a precaution, .Nm may decide to represent such a symbolic link as a regular file which contains the link's target path, rather than creating an actual symbolic link which points outside of the work tree. Use of this option is discouraged because external mechanisms such as .Dq make obj are better suited for managing symbolic links to paths not under version control. .El .Pp .Cm got stage will refuse to run if certain preconditions are not met. If a file contains merge conflicts, these conflicts must be resolved first. If a file is found to be out of date relative to the head commit on the work tree's current branch, the file must be updated with .Cm got update before it can be staged (however, this does not prevent the file from becoming out-of-date at some point after having been staged). .Pp The .Cm got update , .Cm got rebase , .Cm got merge , and .Cm got histedit commands will refuse to run while staged changes exist.

An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, .Sy :head:-2 denotes the work tree branch head's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy quux:-8 will denote the 8th generation ancestor of the commit resolved by the .Qq quux reference. A .Qq :+ or .Qq :- modifier without a trailing integer has an implicit .Qq 1 appended .Po e.g., .Sy :base:+ is equivalent to .Sy :base:+1 .Pc . .It Fl P Interpret all arguments as paths only.

Patterns from each .Pa .cvsignore or .Pa .gitignore file are matched relative to the directory containing that file. If a pattern begins with two asterisks followed by a slash, .Dq **/ , the remainder of the pattern will match at any directory at or below the directory containing .Pa .cvsignore or .Pa gitignore file. Two asterisks surrounded by slashes, .Dq /**/ , in the middle of a pattern will match one directory or more. Patterns which end with a slash, .Dq / , will only match directories, and any paths below matching directories will be ignored. .Pp Unlike .Xr cvs 1 , .Nm only supports a single ignore pattern per line. Unlike .Xr git 1 , .Nm does not support negated ignore patterns prefixed with .Dq \&! , and does not match patterns at arbitrary depth relative to the .Pa .gitignore file unless they begin with .Dq **/ .

This new commit will become the head commit of the work tree's current branch: .Pp .Dl $ got commit .Pp In a work tree or a git repository directory, view changes committed in the 3 most recent commits to the work tree's branch, or the branch resolved via the repository's HEAD reference, respectively: .Pp .Dl $ got log -p -l 3 .Pp As above, but display changes in the order in which .Xr patch 1 could apply them in sequence: .Pp .Dl $ got log -p -l 3 -R .Pp In a work tree or a git repository directory, log the history of a subdirectory: .Pp .Dl $ got log sys/uvm .Pp While operating inside a work tree, paths are specified relative to the current working directory, so this command will log the subdirectory .Pa sys/uvm : .Pp .Dl $ cd sys/uvm && got log\ . .Pp And this command has the same effect: .Pp .Dl $ cd sys/dev/usb && got log ../../uvm .Pp And this command displays work tree meta-data about all tracked files: .Pp .Dl $ cd /usr/src .Dl $ got info\ . | less .Pp Add new files and remove obsolete files in a work tree directory: .Pp .Dl $ got add sys/uvm/uvm_ubc.c .Dl $ got remove sys/uvm/uvm_vnode.c .Pp A file can be renamed or moved by removing it from its old location and adding it at the new location: .Pp .Dl $ cp oldfile.c newfile.c .Dl $ got remove oldfile.c .Dl $ got add newfile.c .Pp .Nm does not yet follow file history across renames, but .Xr git 1 will be able to do so regardless. .Pp Create a new commit from local changes in a work tree directory with a pre-defined log message. .Pp .Dl $ got commit -m 'unify the buffer cache' .Pp Alternatively, create a new commit from local changes in a work tree directory with a log message that has been prepared in the file .Pa /tmp/msg : .Pp .Dl $ got commit -F /tmp/msg .Pp Update any work tree checked out from the .Dq unified-buffer-cache branch to the latest commit on this branch: .Pp .Dl $ got update .Pp Roll file content on the unified-buffer-cache branch back by one commit, and then fetch the rolled-back change into the work tree as a local change to be amended and perhaps committed again: .Pp .Dl $ got backout unified-buffer-cache .Dl $ got commit -m 'roll back previous' .Dl $ # now back out the previous backout :-) .Dl $ got backout unified-buffer-cache .Pp Fetch new changes on the remote repository's .Dq master branch, making them visible on the local repository's .Dq origin/master branch: .Pp .Dl $ cd /usr/src .Dl $ got fetch .Pp Rebase the local .Dq master branch to merge the new changes that are now visible on the .Dq origin/master branch: .Pp .Dl $ cd /usr/src .Dl $ got update -b origin/master .Dl $ got rebase master .Pp Rebase the .Dq unified-buffer-cache branch on top of the new head commit of the .Dq master branch. .Pp .Dl $ got update -b master .Dl $ got rebase unified-buffer-cache .Pp Create a patch from all changes on the unified-buffer-cache branch. The patch can be mailed out for review and applied to .Ox Ns 's CVS tree: .Pp .Dl $ got diff master unified-buffer-cache > /tmp/ubc.diff .Pp Edit the entire commit history of the .Dq unified-buffer-cache branch: .Pp .Dl $ got update -b unified-buffer-cache .Dl $ got update -c master .Dl $ got histedit .Pp Before working against existing branches in a repository cloned with .Cm git clone --bare instead of .Cm got clone , a Git .Dq refspec must be configured to map all references in the remote repository into the .Dq refs/remotes namespace of the local repository. This can be achieved by setting Git's .Pa remote.origin.fetch configuration variable to the value .Dq +refs/heads/*:refs/remotes/origin/* with the .Cm git config command: .Pp .Dl $ cd /var/git/repo .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*' .Pp Additionally, the .Dq mirror option must be disabled: .Pp .Dl $ cd /var/git/repo .Dl $ git config remote.origin.mirror false .Pp Alternatively, the following .Xr git-fetch 1 configuration item can be added manually to the Git repository's .Pa config file: .Pp .Dl [remote \&"origin\&"] .Dl url = ... .Dl fetch = +refs/heads/*:refs/remotes/origin/* .Dl mirror = false .Pp This configuration leaves the local repository's .Dq refs/heads namespace free for use by local branches checked out with .Cm got checkout and, if needed, created with .Cm got branch . Branches in the .Dq refs/remotes/origin namespace can now be updated with incoming changes from the remote repository with .Cm got fetch or .Xr git-fetch 1 without extra command line arguments. Newly fetched changes can be examined with .Cm got log . .Pp Display changes on the remote repository's version of the .Dq master branch, as of the last time .Cm got fetch was run: .Pp .Dl $ got log -c origin/master | less .Pp As shown here, most commands accept abbreviated reference names such as .Dq origin/master instead of .Dq refs/remotes/origin/master . The latter is only needed in case of ambiguity. .Pp .Cm got rebase can be used to merge changes which are visible on the .Dq origin/master branch into the .Dq master branch. This will also merge local changes, if any, with the incoming changes: .Pp .Dl $ got update -b origin/master .Dl $ got rebase master .Pp In order to make changes committed to the .Dq unified-buffer-cache visible on the .Dq master branch, the .Dq unified-buffer-cache branch can be rebased onto the .Dq master branch: .Pp .Dl $ got update -b master .Dl $ got rebase unified-buffer-cache .Pp Changes on the .Dq unified-buffer-cache branch can now be made visible on the .Dq master branch with .Cm got integrate . Because the rebase operation switched the work tree to the .Dq unified-buffer-cache branch, the work tree must be switched back to the .Dq master branch first: .Pp .Dl $ got update -b master .Dl $ got integrate unified-buffer-cache .Pp On the .Dq master branch, log messages for local changes can now be amended with .Dq OK by other developers and any other important new information: .Pp .Dl $ got update -c origin/master .Dl $ got histedit -m .Pp If the remote repository offers write access, local changes on the .Dq master branch can be sent to the remote repository with .Cm got send . Usually, .Cm got send can be run without further arguments. The arguments shown here match defaults, provided the work tree's current branch is the .Dq master branch: .Pp .Dl $ got send -b master origin .Pp If the remote repository requires the HTTPS protocol, the .Xr git-push 1 command must be used instead: .Pp .Dl $ cd /var/git/src.git .Dl $ git push origin master .Pp When making contributions to projects which use the .Dq pull request workflow, SSH protocol repository access needs to be set up first. Once an account has been created on a Git hosting site it should be possible to upload a public SSH key for repository access authentication. .Pp The .Dq pull request workflow will usually involve two remote repositories. In the real-life example below, the .Dq origin repository was forked from the .Dq upstream repository by using the Git hosting site's web interface. The .Xr got.conf 5 file in the local repository describes both remote repositories: .Bd -literal -offset indent # Jelmers's repository, which accepts pull requests remote "upstream" { server git@github.com protocol ssh repository "/jelmer/dulwich" branch { "master" } } # Stefan's fork, used as the default remote repository remote "origin" { server git@github.com protocol ssh repository "/stspdotname/dulwich" branch { "master" } } .Ed .Pp With this configuration, Stefan can create commits on .Dq refs/heads/master and send them to the .Dq origin repository by running: .Pp .Dl $ got send -b master origin .Pp The changes can now be proposed to Jelmer by opening a pull request via the Git hosting site's web interface. If Jelmer requests further changes to be made, additional commits can be created on the .Dq master branch and be added to the pull request by running .Cd got send again. .Pp If Jelmer prefers additional commits to be .Dq squashed then the following commands can be used to achieve this: .Pp .Dl $ got update -b master .Dl $ got update -c origin/master .Dl $ got histedit -f .Dl $ got send -f -b master origin .Pp In addition to reviewing the pull request in the web user interface, Jelmer can fetch the pull request's branch into his local repository and create a local branch which contains the proposed changes: .Pp .Dl $ got fetch -R refs/pull/1046/head origin .Dl $ got branch -c refs/remotes/origin/pull/1046/head pr1046 .Pp Once Jelmer has accepted the pull request, Stefan can fetch the merged changes, and possibly several other new changes, by running: .Pp .Dl $ got fetch upstream .Pp The merged changes will now be visible under the reference .Dq refs/remotes/upstream/master . The local .Dq master branch can now be rebased on top of the latest changes from upstream: .Pp .Dl $ got update -b upstream/master .Dl $ got rebase master .Pp As an alternative to .Cm got rebase , branches can be merged with .Cm got merge : .Pp .Dl $ got update -b master .Dl $ got merge upstream/master .Pp The question of whether to rebase or merge branches is philosophical. When in doubt, refer to the software project's policies set by project maintainers. .Pp As a final step, the forked repository's copy of the master branch needs to be kept in sync by sending the new changes there: .Pp .Dl $ got send -f -b master origin .Pp If multiple pull requests need to be managed in parallel, a separate branch must be created for each pull request with .Cm got branch . Each such branch can then be used as above, in place of .Dq refs/heads/master . Changes for any accepted pull requests will still appear under .Dq refs/remotes/upstream/master, regardless of which branch was used in the forked repository to create a pull request. .Sh SEE ALSO .Xr gotadmin 1 , .Xr tog 1 , .Xr git-repository 5 , .Xr got-worktree 5 , .Xr got.conf 5 , .Xr gotwebd 8 .Sh AUTHORS .An Anthony J.

Comments can be put anywhere in the file using a hash mark .Pq Sq # , and extend to the end of the current line. Arguments names not beginning with a letter, digit or underscore, as well as reserved words .Pq such as Ic author , Ic remote No or Ic port , must be quoted. Arguments containing whitespace should be surrounded by double quotes .Pq \&" . .Pp The available configuration directives are as follows: .Bl -tag -width Ds .It Ic author Dq Real Name Configure the author's name and email address for .Cm got commit and .Cm got import when operating on this repository. Author information specified here overrides the .Ev GOT_AUTHOR environment variable. .Pp Because .Xr git 1 may fail to parse commits without an email address in author data, .Xr got 1 attempts to reject author information with a missing email address. .It Ic signer_id Pa signer-id Configure a .Ar signer-id to sign tag objects. This key will be used to sign all tag objects unless overridden by .Cm got tag Fl s Ar signer-id . .Pp For SSH-based signatures, .Ar signer-id is the path to a file which may refer to either a private SSH key, or a public SSH key with the private half available via .Xr ssh-agent 1 . .It Ic allowed_signers Pa path Configure a .Ar path to the "allowed signers" file which contains a list of trusted SSH signer identities. The file will be passed to .Xr ssh-keygen 1 during verification of SSH-based signatures with .Cm got tag Fl V . The format of the "allowed signers" file is documented in the ALLOWED SIGNERS section of .Xr ssh-keygen 1 . .Pp Verification of SSH-based signatures is impossible unless the .Ic allowed_signers option is set in .Nm . .It Ic revoked_signers Pa path Configure a .Ar path to the optional "revoked signers" file, which contains a list of revoked SSH signer identities. This file is passed to .Xr ssh-keygen 1 during signature verification with .Cm got tag Fl V . Revoked identities are no longer considered trustworthy and verification of relevant signatures will fail. .It Ic remote Ar name Brq ... Define a remote repository. The specified .Ar name can be used to refer to the remote repository on the command line of .Cm got fetch and .Cm got send . .Pp When repositories are shared between multiple users on the system, it is recommended that users configure their trusted remote repositories in each of their work-trees' .Nm files, overriding corresponding repository-wide settings. This can avoid potentially undesirable connections to remote repositories placed into the shared repository's .Nm file by other users. .Pp Information about a repository is declared in a block of options enclosed in curly brackets: .Bl -tag -width Ds .It Ic server Ar hostname Defines the hostname to use for contacting the remote repository's server. .It Ic repository Ar path Defines the path to the repository on the remote repository's server. .It Ic protocol Ar scheme Defines the protocol to use for communicating with the remote repository's server. .Pp The following protocol schemes are supported: .Bl -tag -width https .It git The Git protocol as implemented by the .Xr git-daemon 1 server. Use of this protocol is discouraged since it supports neither authentication nor encryption. .It ssh The Git protocol wrapped in an authenticated and encrypted .Xr ssh 1 tunnel. With this protocol the hostname may contain an embedded username for .Xr ssh 1 to use: .Mt user@hostname .It http The .Dq smart Git HTTP protocol. Not compatible with servers using the .Dq dumb Git HTTP protocol. .Pp The .Dq smart Git HTTP protocol is supported by .Cm got clone and .Cm got fetch , but not by .Cm got send . To send from a repository cloned over HTTP, add a .Ic send block (see below) to ensure that the .Dq ssh:// protocol will be used by .Cm got send . .Pp Use of this protocol is discouraged since it supports neither authentication nor encryption. .It https The .Dq smart Git HTTP protocol wrapped in SSL/TLS. .El .It Ic port Ar port Defines the port to use for connecting to the remote repository's server. The .Ar port can be specified by number or name. The port name to number mappings are found in the file .Pa /etc/services ; see .Xr services 5 for details. If not specified, the default port of the specified .Cm protocol will be used. .It Ic branch Brq Ar branch ... Specify one or more branches which .Cm got fetch and .Cm got send should fetch from and send to the remote repository by default. The list of branches specified here can be overridden at the .Cm got fetch and .Cm got send command lines with the .Fl b option. .It Ic fetch_all_branches Ar yes | no This option controls whether .Cm got fetch will fetch all branches from the remote repository by default. If enabled, this behaviour can be overridden at the .Cm got fetch command line with the .Fl b option, and any .Cm branch configuration settings for this remote repository will be ignored. .It Ic reference Brq Ar reference ... Specify one or more arbitrary references which .Cm got fetch should fetch by default, in addition to the branches and tags that will be fetched. The list of references specified here can be overridden at the .Cm got fetch command line with the .Fl R option. .Cm got fetch will refuse to fetch references from the remote repository's .Dq refs/remotes/ or .Dq refs/got/ namespace. In any case, references in the .Dq refs/tags/ namespace will always be fetched and mapped directly to local references in the same namespace. .It Ic mirror_references Ar yes | no This option controls the behaviour of .Cm got fetch when updating references. .Sy Enabling this option can lead to the loss of local commits. Maintaining custom changes in a mirror repository is therefore discouraged. .Pp If this option is not specified or set to .Ar no , .Cm got fetch will map references of the remote repository into the local repository's .Dq refs/remotes/ namespace. .Pp If this option is set to .Ar yes , all branches in the .Dq refs/heads/ namespace will be updated directly to match the corresponding branches in the remote repository. .It Ic fetch Brq ... An optional .Ic fetch block may contain any of the following configuration settings for use by .Cm got fetch , overriding corresponding settings in the containing .Ic remote Ar name Brq ... block. .Bl -bullet .It .Ic server Ar hostname .It .Ic repository Ar path .It .Ic protocol Ar scheme .It .Ic port Ar port .It .Ic branch Brq Ar branch ... .El .It Ic send Brq ... An optional .Ic send block may contain any of the following configuration settings for use by .Cm got send , overriding corresponding settings in the containing .Ic remote Ar name Brq ... block. .Bl -bullet .It .Ic server Ar hostname .It .Ic repository Ar path .It .Ic protocol Ar scheme .It .Ic port Ar port .It .Ic branch Brq Ar branch ... .El .El .El .Sh FILES .Bl -tag -width Ds -compact .It Pa got.conf If present, .Nm located in the root directory of a Git repository supersedes any relevant settings in Git's .Pa config file. .Pp .It Pa .got/got.conf If present, .Nm located in the .Pa .got meta-data directory of a .Xr got 1 work tree supersedes any relevant settings in the repository's .Nm configuration file and Git's .Pa config file. .El .Sh EXAMPLES Configure author information: .Bd -literal -offset indent author "Flan Hacker " .Ed .Pp Remote repository specification for the Game of Trees repository: .Bd -literal -offset indent remote "origin" { server anonymous@got.gameoftrees.org protocol ssh repository got branch { "main" } } .Ed .Pp Mirror the .Ox src repository from Github: .Bd -literal -offset indent remote "origin" { repository "openbsd/src" server git@github.com protocol git+ssh mirror_references yes } .Ed .Pp Fetch changes via the Git protocol and send changes via the SSH protocol: .Bd -literal -offset indent remote "origin" { repository my_repo server git.example.com protocol git send { server git@git.example.com protocol ssh } } .Ed .Sh SEE ALSO .Xr got 1 , .Xr git-repository 5 , .Xr got-worktree 5 .Sh CAVEATS .Nm offers no way to configure the editor spawned by .Cm got commit , .Cm got histedit , .Cm got import , or .Cm got tag . This is deliberate and prevents potential arbitrary command execution as another user when repositories or work trees are shared between users. Users should set their .Ev VISUAL or .Ev EDITOR environment variables instead. got-portable-0.119/got/Makefile.in0000664000175000017500000014545315066537207012473 # Makefile.in generated by automake 1.17 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2024 Free Software Foundation, Inc. # This Makefile.in is free software;

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

The Git repository format is described in .Xr git-repository 5 . .Pp Files managed by .Nm must be checked out from the repository for modification. Checked out files are stored in a .Em work tree which can be placed at an arbitrary directory in the filesystem hierarchy. The on-disk format of this work tree is described in .Xr cvg-worktree 5 . .Pp .Nm provides global and command-specific options. Global options must precede the command name, and are as follows: .Bl -tag -width tenletters .It Fl h Display usage information and exit immediately. .It Fl V , -version Display program version and exit immediately. .El .Pp The commands for .Nm are as follows: .Bl -tag -width checkout .Tg im .It Xo .Cm import .Op Fl b Ar branch .Op Fl I Ar pattern .Op Fl m Ar message .Op Fl r Ar repository-path .Ar directory .Xc .Dl Pq alias: Cm im Create an initial commit in a repository from the file hierarchy within the specified .Ar directory . The created commit will not have any parent commits, i.e. it will be a root commit. Also create a new reference which provides a branch name for the newly created commit. Show the path of each imported file to indicate progress. .Pp The .Cm got import command requires the .Ev GOT_AUTHOR environment variable to be set, unless an author has been configured in .Xr got.conf 5 or Git's .Dv user.name and .Dv user.email configuration settings can be obtained from the repository's .Pa .git/config file or from Git's global .Pa ~/.gitconfig configuration file. .Pp The options for .Cm got import are as follows: .Bl -tag -width Ds .It Fl b Ar branch Create the specified .Ar branch . If this option is not specified, a branch corresponding to the repository's HEAD reference will be used. Use of this option is required if the branch resolved via the repository's HEAD reference already exists. .It Fl I Ar pattern Ignore files or directories with a name which matches the specified .Ar pattern . This option may be specified multiple times to build a list of ignore patterns. The .Ar pattern follows the globbing rules documented in .Xr glob 7 . Ignore patterns which end with a slash, .Dq / , will only match directories. .It Fl m Ar message Use the specified log message when creating the new commit. Without the .Fl m option, .Cm got import opens a temporary file in an editor where a log message can be written. Quitting the editor without saving the file will abort the import operation. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. .El .Tg cl .It Xo .Cm clone .Op Fl almqv .Op Fl b Ar branch .Op Fl i Ar identity-file .Op Fl J Ar jumphost .Op Fl R Ar reference .Ar repository-URL .Op Ar directory .Xc .Dl Pq alias: Cm cl Clone a Git repository at the specified .Ar repository-URL into the specified .Ar directory . If no .Ar directory is specified, the directory name will be derived from the name of the cloned repository. .Cm got clone will refuse to run if the .Ar directory already exists. .Pp The .Ar repository-URL specifies a protocol scheme, a server hostname, an optional port number separated from the hostname by a colon, and a path to the repository on the server: .Lk scheme://hostname:port/path/to/repository .Pp The following protocol schemes are supported: .Bl -tag -width git+ssh .It git The Git protocol as implemented by the .Xr git-daemon 1 server. Use of this protocol is discouraged since it supports neither authentication nor encryption. .It git+ssh The Git protocol wrapped in an authenticated and encrypted .Xr ssh 1 tunnel. With this protocol the hostname may contain an embedded username for .Xr ssh 1 to use: .Mt user@hostname .It ssh Short alias for git+ssh. .El .Pp Objects in the cloned repository are stored in a pack file which is downloaded from the server. This pack file will then be indexed to facilitate access to the objects stored within. If any objects in the pack file are stored in deltified form, all deltas will be fully resolved in order to compute the ID of such objects. This can take some time. More details about the pack file format are documented in .Xr git-repository 5 . .Pp .Cm got clone creates a remote repository entry in the .Xr got.conf 5 and .Pa config files of the cloned repository to store the .Ar repository-url and any .Ar branch or .Ar reference arguments for future use by .Cm got fetch or .Xr git-fetch 1 . .Pp The options for .Cm got clone are as follows: .Bl -tag -width Ds .It Fl a Fetch all branches from the remote repository's .Dq refs/heads/ reference namespace and set .Cm fetch_all_branches in the cloned repository's .Xr got.conf 5 file for future use by .Cm got fetch . If this option is not specified, a branch resolved via the remote repository's HEAD reference will be fetched. Cannot be used together with the .Fl b option. .It Fl b Ar branch Fetch the specified .Ar branch from the remote repository's .Dq refs/heads/ reference namespace. This option may be specified multiple times to build a list of branches to fetch. If the branch corresponding to the remote repository's HEAD reference is not in this list, the cloned repository's HEAD reference will be set to the first branch which was fetched. If this option is not specified, a branch resolved via the remote repository's HEAD reference will be fetched. Cannot be used together with the .Fl a option. .It Fl i Ar identity-file Specify an .Ar identity-file , containing a private SSH key, to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl J Ar jumphost Specify a .Ar jumphost to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl l List branches and tags available for fetching from the remote repository and exit immediately. Cannot be used together with any of the other options except .Fl q and .Fl v . .It Fl m Create the cloned repository as a mirror of the original repository. This is useful if the cloned repository will not be used to store locally created commits. .Pp The repository's .Xr got.conf 5 and .Pa config files will be set up with the .Dq mirror option enabled, such that .Cm got fetch or .Xr git-fetch 1 will write incoming changes directly to branches in the .Dq refs/heads/ reference namespace, rather than to branches in the .Dq refs/remotes/ namespace. This avoids the usual requirement of having to run .Cm got rebase or .Cm got merge after .Cm got fetch in order to make incoming changes appear on branches in the .Dq refs/heads/ namespace. But maintaining custom changes in the cloned repository becomes difficult since such changes will be at risk of being discarded whenever incoming changes are fetched. .It Fl q Suppress progress reporting output. The same option will be passed to .Xr ssh 1 if applicable. .It Fl R Ar reference In addition to the branches and tags that will be fetched, fetch an arbitrary .Ar reference from the remote repository's .Dq refs/ namespace. This option may be specified multiple times to build a list of additional references to fetch. The specified .Ar reference may either be a path to a specific reference, or a reference namespace which will cause all references in this namespace to be fetched. .Pp Each reference will be mapped into the cloned repository's .Dq refs/remotes/ namespace, unless the .Fl m option is used to mirror references directly into the cloned repository's .Dq refs/ namespace. .Pp .Cm got clone will refuse to fetch references from the remote repository's .Dq refs/remotes/ or .Dq refs/got/ namespace. .It Fl v Verbose mode. Causes .Cm got clone to print debugging messages to standard error output. This option will be passed to .Xr ssh 1 if applicable. Multiple -v options increase the verbosity. The maximum is 3. .El .Tg co .It Xo .Cm checkout .Op Fl Eq .Op Fl b Ar branch .Op Fl c Ar commit .Op Fl p Ar path-prefix .Ar repository-path .Op Ar work-tree-path .Xc .Dl Pq alias: Cm co Copy files from a repository into a new work tree. Show the status of each affected file, using the following status codes: .Bl -column YXZ description .It A Ta new file was added .It E Ta file already exists in work tree's meta-data .El .Pp If the .Ar work tree path is not specified, either use the last component of .Ar repository path , or if a .Ar path prefix was specified use the last component of .Ar path prefix . .Pp The options for .Cm got checkout are as follows: .Bl -tag -width Ds .It Fl b Ar branch Check out files from a commit on the specified .Ar branch . If this option is not specified, a branch resolved via the repository's HEAD reference will be used. .It Fl c Ar commit Check out files from the specified .Ar commit on the selected branch. The expected argument is a commit ID or an existing reference or tag name which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a commit ID automatically, provided the abbreviation is unique. If this option is not specified, the most recent commit on the selected branch will be used. .Pp If the specified .Ar commit is not contained in the selected branch, a different branch which contains this commit must be specified with the .Fl b option. If no such branch is known, a new branch must be created for this commit with .Cm got branch before .Cm got checkout can be used. Checking out work trees with an unknown branch is intentionally not supported. .It Fl E Proceed with the checkout operation even if the directory at .Ar work-tree-path is not empty. Existing files will be left intact. .It Fl p Ar path-prefix Restrict the work tree to a subset of the repository's tree hierarchy. Only files beneath the specified .Ar path-prefix will be checked out. .It Fl q Silence progress output. .El .Tg up .It Xo .Cm update .Op Fl q .Op Fl b Ar branch .Op Fl c Ar commit .Op Fl i Ar identity-file .Op Fl J Ar jumphost .Op Ar path ... .Xc .Dl Pq alias: Cm up Update an existing work tree to a different .Ar commit . Change existing files in the work tree as necessary to match file contents of this commit. Preserve any local changes in the work tree and merge them with the incoming changes. .Pp Files which already contain merge conflicts will not be updated to avoid further complications. Such files will be updated when .Cm got update is run again after merge conflicts have been resolved. If the conflicting changes are no longer needed, affected files can be reverted with .Cm got revert before running .Cm got update again. .Pp Show the status of each affected file, using the following status codes: .Bl -column YXZ description .It U Ta file was updated and contained no local changes .It G Ta file was updated and local changes were merged cleanly .It C Ta file was updated and conflicts occurred during merge .It D Ta file was deleted .It d Ta file's deletion was prevented by local modifications .It A Ta new file was added .It \(a~ Ta versioned file is obstructed by a non-regular file .It ! Ta a missing versioned file was restored .It # Ta file was not updated because it contains merge conflicts .It ? Ta changes destined for an unversioned file were not merged .El .Pp If no .Ar path is specified, update the entire work tree. Otherwise, restrict the update operation to files at or within the specified paths. Each path is required to exist in the update operation's target commit. Files in the work tree outside specified paths will remain unchanged and will retain their previously recorded base commit. Some .Nm commands may refuse to run while the work tree contains files from multiple base commits. The base commit of such a work tree can be made consistent by running .Cm got update across the entire work tree. Specifying a .Ar path is incompatible with the .Fl b option. .Pp .Cm got update cannot update paths with staged changes. If changes have been staged with .Cm got stage , these changes must first be committed with .Cm got commit or unstaged with .Cm got unstage . .Pp The options for .Cm got update are as follows: .Bl -tag -width Ds .It Fl b Ar branch Switch the work tree's branch reference to the specified .Ar branch before updating the work tree. This option requires that all paths in the work tree are updated. .Pp As usual, any local changes in the work tree will be preserved. This can be useful when switching to a newly created branch in order to commit existing local changes to this branch. .Pp Any local changes must be dealt with separately in order to obtain a work tree with pristine file contents corresponding exactly to the specified .Ar branch . Such changes could first be committed to a different branch with .Cm got commit , or could be discarded with .Cm got revert . .It Fl c Ar commit Update the work tree to the specified .Ar commit . The expected argument is a commit ID or an existing reference or tag name which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a commit ID automatically, provided the abbreviation is unique. If this option is not specified, the most recent commit on the work tree's branch will be used. .It Fl i Ar identity-file Specify an .Ar identity-file , containing a private SSH key, to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl J Ar jumphost Specify a .Ar jumphost to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl q Silence progress output. .El .Tg st .It Xo .Cm status .Op Fl I .Op Fl S Ar status-codes .Op Fl s Ar status-codes .Op Ar path ... .Xc .Dl Pq alias: Cm st Show the current modification status of files in a work tree, using the following status codes: .Bl -column YXZ description .It M Ta modified file .It A Ta file scheduled for addition in next commit .It D Ta file scheduled for deletion in next commit .It C Ta modified or added file which contains merge conflicts .It ! Ta versioned file was expected on disk but is missing .It \(a~ Ta versioned file is obstructed by a non-regular file .It ? Ta unversioned item not tracked by .Nm .It m Ta modified file modes (executable bit only) .It N Ta non-existent .Ar path specified on the command line .El .Pp If no .Ar path is specified, show modifications in the entire work tree. Otherwise, show modifications at or within the specified paths. .Pp If changes have been staged with .Cm got stage , staged changes are shown in the second output column, using the following status codes: .Bl -column YXZ description .It M Ta file modification is staged .It A Ta file addition is staged .It D Ta file deletion is staged .El .Pp Changes created on top of staged changes are indicated in the first column: .Bl -column YXZ description .It MM Ta file was modified after earlier changes have been staged .It MA Ta file was modified after having been staged for addition .El .Pp The options for .Cm got status are as follows: .Bl -tag -width Ds .It Fl I Show unversioned files even if they match an ignore pattern. See .Sx Ignore Patterns . .It Fl S Ar status-codes Suppress the output of files with a modification status matching any of the single-character status codes contained in the .Ar status-codes argument. Any combination of codes from the above list of possible status codes may be specified. For staged files, status codes displayed in either column will be matched. Cannot be used together with the .Fl s option. .It Fl s Ar status-codes Only show files with a modification status matching any of the single-character status codes contained in the .Ar status-codes argument. Any combination of codes from the above list of possible status codes may be specified. For staged files, status codes displayed in either column will be matched. Cannot be used together with the .Fl S option. .El .It Xo .Cm log .Op Fl bdPpRs .Op Fl C Ar number .Op Fl c Ar commit .Op Fl l Ar N .Op Fl r Ar repository-path .Op Fl S Ar search-pattern .Op Fl x Ar commit .Op Ar path .Xc Display history of a repository. If a .Ar path is specified, show only commits which modified this path. If invoked in a work tree, the .Ar path is interpreted relative to the current working directory, and the work tree's path prefix is implicitly prepended. Otherwise, the path is interpreted relative to the repository root. .Pp The options for .Cm got log are as follows: .Bl -tag -width Ds .It Fl b Display individual commits which were merged into the current branch from other branches. By default, .Cm got log shows the linear history of the current branch only. .It Fl C Ar number Set the number of context lines shown in diffs with .Fl p . By default, 3 lines of context are shown. .It Fl c Ar commit Start traversing history at the specified .Ar commit . The expected argument is a commit ID or an existing reference or tag name which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a commit ID automatically, provided the abbreviation is unique. If this option is not specified, default to the work tree's current branch if invoked in a work tree, or to the repository's HEAD reference. .It Fl d Display diffstat of changes introduced in each commit. Cannot be used with the .Fl s option. .It Fl l Ar N Limit history traversal to a given number of commits. If this option is not specified, a default limit value of zero is used, which is treated as an unbounded limit. The .Ev GOT_LOG_DEFAULT_LIMIT environment variable may be set to change this default value. .It Fl P Display the list of file paths changed in each commit, using the following status codes: .Bl -column YXZ description .It M Ta modified file .It D Ta file was deleted .It A Ta new file was added .It m Ta modified file modes (executable bit only) .El .Pp Cannot be used with the .Fl s option. .It Fl p Display the patch of modifications made in each commit. If a .Ar path is specified, only show the patch of modifications at or within this path. Cannot be used with the .Fl s option. .It Fl R Determine a set of commits to display as usual, but display these commits in reverse order. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .It Fl S Ar search-pattern If specified, show only commits with a log message, author name, committer name, or commit ID matched by the extended regular expression .Ar search-pattern . Lines in committed patches will be matched if .Fl p is specified. File paths changed by a commit will be matched if .Fl P is specified. Regular expression syntax is documented in .Xr re_format 7 . .It Fl s Display a short one-line summary of each commit, instead of the default history format. Cannot be used together with the .Fl p or .Fl P option. .It Fl x Ar commit Stop traversing commit history immediately after the specified .Ar commit has been traversed. This option has no effect if the specified .Ar commit is never traversed. .El .Tg di .It Xo .Cm diff .Op Fl adPsw .Op Fl C Ar number .Op Fl c Ar commit .Op Fl r Ar repository-path .Op Ar object1 Ar object2 | Ar path ... .Xc .Dl Pq alias: Cm di When invoked within a work tree without any arguments, display all local changes in the work tree. If one or more .Ar path arguments are specified, only show changes within the specified paths. .Pp If two arguments are provided, treat each argument as a reference, a tag name, or an object ID, and display differences between the corresponding objects. Both objects must be of the same type (blobs, trees, or commits). An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. If none of these interpretations produce a valid result or if the .Fl P option is used, and if .Cm got diff is running in a work tree, attempt to interpret the two arguments as paths. .Pp The options for .Cm got diff are as follows: .Bl -tag -width Ds .It Fl a Treat file contents as ASCII text even if binary data is detected. .It Fl C Ar number Set the number of context lines shown in the diff. By default, 3 lines of context are shown. .It Fl c Ar commit Show differences between commits in the repository. This option may be used up to two times. When used only once, show differences between the specified .Ar commit and its first parent commit. When used twice, show differences between the two specified commits. .Pp The expected argument is a commit ID or an existing reference or tag name which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a commit ID automatically, provided the abbreviation is unique. .Pp If the .Fl c option is used, all non-option arguments will be interpreted as paths. If one or more such .Ar path arguments are provided, only show differences for the specified paths. .Pp Cannot be used together with the .Fl P option. .It Fl d Display diffstat of changes before the actual diff by annotating each file path or blob hash being diffed with the total number of lines added and removed. A summary line will display the total number of changes across all files. .It Fl P Interpret all arguments as paths only. This option can be used to resolve ambiguity in cases where paths look like tag names, reference names, or object IDs. This option is only valid when .Cm got diff is invoked in a work tree. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .It Fl s Show changes staged with .Cm got stage instead of showing local changes in the work tree. This option is only valid when .Cm got diff is invoked in a work tree. .It Fl w Ignore whitespace-only changes. .El .Tg bl .It Xo .Cm blame .Op Fl c Ar commit .Op Fl r Ar repository-path .Ar path .Xc .Dl Pq alias: Cm bl Display line-by-line history of a file at the specified path. .Pp The options for .Cm got blame are as follows: .Bl -tag -width Ds .It Fl c Ar commit Start traversing history at the specified .Ar commit . The expected argument is a commit ID or an existing reference or tag name which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a commit ID automatically, provided the abbreviation is unique. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .El .Tg tr .It Xo .Cm tree .Op Fl iR .Op Fl c Ar commit .Op Fl r Ar repository-path .Op Ar path .Xc .Dl Pq alias: Cm tr Display a listing of files and directories at the specified directory path in the repository. Entries shown in this listing may carry one of the following trailing annotations: .Bl -column YXZ description .It @ Ta entry is a symbolic link .It / Ta entry is a directory .It * Ta entry is an executable file .It $ Ta entry is a Git submodule .El .Pp Symbolic link entries are also annotated with the target path of the link. .Pp If no .Ar path is specified, list the repository path corresponding to the current directory of the work tree, or the root directory of the repository if there is no work tree. .Pp The options for .Cm got tree are as follows: .Bl -tag -width Ds .It Fl c Ar commit List files and directories as they appear in the specified .Ar commit . The expected argument is a commit ID or an existing reference or tag name which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a commit ID automatically, provided the abbreviation is unique. .It Fl i Show object IDs of files (blob objects) and directories (tree objects). .It Fl R Recurse into sub-directories in the repository. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .El .It Xo .Cm tag .Op Fl lVv .Op Fl c Ar commit .Op Fl m Ar message .Op Fl r Ar repository-path .Op Fl s Ar signer-id .Ar name .Xc Manage tags in a repository. .Pp Tags are managed via references which live in the .Dq refs/tags/ reference namespace. The .Cm got tag command operates on references in this namespace only. References in this namespace point at tag objects which contain a pointer to another object, a tag message, as well as author and timestamp information. .Pp Attempt to create a tag with the given .Ar name , and make this tag point at the given .Ar commit . If no commit is specified, default to the latest commit on the work tree's current branch if invoked in a work tree, and to a commit resolved via the repository's HEAD reference otherwise. .Pp The options for .Cm got tag are as follows: .Bl -tag -width Ds .It Fl c Ar commit Make the newly created tag reference point at the specified .Ar commit . The expected .Ar commit argument is a commit ID or an existing reference or tag name which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a commit ID automatically, provided the abbreviation is unique. .It Fl l List all existing tags in the repository instead of creating a new tag. If a .Ar name argument is passed, show only the tag with the given .Ar name . .It Fl m Ar message Use the specified tag message when creating the new tag. Without the .Fl m option, .Cm got tag opens a temporary file in an editor where a tag message can be written. Quitting the editor without saving the file will abort the tag operation. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Nm work tree, use the repository path associated with this work tree. .It Fl s Ar signer-id While creating a new tag, sign this tag with the identity given in .Ar signer-id . .Pp For SSH-based signatures, .Ar signer-id is the path to a file which may refer to either a private SSH key, or a public SSH key with the private half available via .Xr ssh-agent 1 . .Cm got tag will sign the tag object by invoking .Xr ssh-keygen 1 with the .Fl Y Cm sign command, using the signature namespace .Dq git for compatibility with .Xr git 1 . .It Fl V Verify tag object signatures. If a .Ar name is specified, show and verify the tag object with the provided name. Otherwise, list all tag objects and verify signatures where present. .Pp .Cm got tag verifies SSH-based signatures by invoking .Xr ssh-keygen 1 with the options .Fl Y Cm verify Fl f Ar allowed_signers . A path to the .Ar allowed_signers file must be set in .Xr got.conf 5 , otherwise verification is impossible. .It Fl v Verbose mode. During SSH signature creation and verification this option will be passed to .Xr ssh-keygen 1 . Multiple -v options increase the verbosity. The maximum is 3. .El .Pp By design, the .Cm got tag command will not delete tags or change existing tags. If a tag must be deleted, the .Cm got ref command may be used to delete a tag's reference. This should only be done if the tag has not already been copied to another repository. .It Xo .Cm add .Op Fl IR .Ar path ... .Xc Schedule unversioned files in a work tree for addition to the repository in the next commit. By default, files which match an ignore pattern will not be added. See .Sx Ignore Patterns . .Pp If a .Ar path mentioned in the command line is not an unversioned file then .Cm got add may raise an error. To avoid unnecessary errors from paths picked up by file globbing patterns in the shell, paths in the argument list will be silently ignored if they are not reported by .Cm got status at all, or if they are reported with one of the following status codes and do not have changes staged via .Cm got stage : .Bl -column YXZ description .It M Ta modified file .It A Ta file scheduled for addition in next commit .It C Ta modified or added file which contains merge conflicts .It m Ta modified file modes (executable bit only) .El .Pp The options for .Cm got add are as follows: .Bl -tag -width Ds .It Fl I Add files even if they match an ignore pattern. See .Xs Ignore Patterns . .It Fl R Permit recursion into directories. If this option is not specified, .Cm got add will refuse to run if a specified .Ar path is a directory. .El .Tg rm .It Xo .Cm remove .Op Fl fkR .Op Fl s Ar status-codes .Ar path ... .Xc .Dl Pq alias: Cm rm Remove versioned files from a work tree and schedule them for deletion from the repository in the next commit. .Pp The options for .Cm got remove are as follows: .Bl -tag -width Ds .It Fl f Perform the operation even if a file contains local modifications, and do not raise an error if a specified .Ar path does not exist on disk. .It Fl k Keep affected files on disk. .It Fl R Permit recursion into directories. If this option is not specified, .Cm got remove will refuse to run if a specified .Ar path is a directory. .It Fl s Ar status-codes Only delete files with a modification status matching one of the single-character status codes contained in the .Ar status-codes argument. The following status codes may be specified: .Bl -column YXZ description .It M Ta modified file (this implies the .Fl f option) .It ! Ta versioned file expected on disk but missing .El .El .Tg pa .It Xo .Cm patch .Op Fl nR .Op Fl c Ar commit .Op Fl p Ar strip-count .Op Ar patchfile .Xc .Dl Pq alias: Cm pa Apply changes from .Ar patchfile to files in a work tree. Files added or removed by a patch will be scheduled for addition or removal in the work tree. .Pp The patch must be in the unified diff format as produced by .Cm got diff , .Xr git-diff 1 , or by .Xr diff 1 and .Xr cvs 1 diff when invoked with their .Fl u options. If no .Ar patchfile argument is provided, read unified diff data from standard input instead. .Pp If the .Ar patchfile contains multiple patches, then attempt to apply each of them in sequence. .Pp Show the status of each affected file, using the following status codes: .Bl -column XYZ description .It M Ta file was modified .It G Ta file was merged using a merge-base found in the repository .It C Ta file was merged and conflicts occurred during merge .It D Ta file was deleted .It A Ta file was added .It # Ta failed to patch the file .El .Pp If a change does not match at its exact line number, attempt to apply it somewhere else in the file if a good spot can be found. Otherwise, the patch will fail to apply. .Pp .Nm .Cm patch will refuse to apply a patch if certain preconditions are not met. Files to be deleted must already be under version control, and must not have been scheduled for deletion already. Files to be added must not yet be under version control and must not already be present on disk. Files to be modified must already be under version control and may not contain conflict markers. .Pp If an error occurs, the .Cm patch operation will be aborted. Any changes made to the work tree up to this point will be left behind. Such changes can be viewed with .Cm got diff and can be reverted with .Cm got revert if needed. .Pp The options for .Cm got patch are as follows: .Bl -tag -width Ds .It Fl c Ar commit Attempt to locate files within the specified .Ar commit for use as a merge-base for 3-way merges. Ideally, the specified .Ar commit should contain versions of files which the changes contained in the .Ar patchfile were based on. Files will be located by path, relative to the repository root. If the .Fl p option is used then leading path components will be stripped before paths are looked up in the repository. .Pp If the .Fl c option is not used then .Cm got patch will attempt to locate merge-bases via object IDs found in .Ar patchfile meta-data, such as produced by .Cm got diff or .Xr git-diff 1 . Use of the .Fl c option is only recommended in the absence of such meta-data. .Pp In case no merge-base is available for a file, changes will be applied without doing a 3-way merge. Changes which do not apply cleanly may then be rejected entirely, rather than producing merge conflicts in the patched target file. .It Fl n Do not make any modifications to the work tree. This can be used to check whether a patch would apply without issues. If the .Ar patchfile contains diffs that affect the same file multiple times, the results displayed may be incorrect. .It Fl p Ar strip-count Specify the number of leading path components to strip from paths parsed from .Ar patchfile . If the .Fl p option is not used, .Sq a/ and .Sq b/ path prefixes generated by .Xr git-diff 1 will be recognized and stripped automatically. .It Fl R Reverse the patch before applying it. .El .Tg rv .It Xo .Cm revert .Op Fl pR .Op Fl F Ar response-script .Ar path ... .Xc .Dl Pq alias: Cm rv Revert any local changes in files at the specified paths in a work tree.

There is no way to bring discarded changes back after .Cm got revert ! .Pp If a file was added with .Cm got add , it will become an unversioned file again. If a file was deleted with .Cm got remove , it will be restored. .Pp The options for .Cm got revert are as follows: .Bl -tag -width Ds .It Fl F Ar response-script With the .Fl p option, read .Dq y , .Dq n , and .Dq q responses line-by-line from the specified .Ar response-script file instead of prompting interactively. .It Fl p Instead of reverting all changes in files, interactively select or reject changes to revert based on .Dq y (revert change), .Dq n (keep change), and .Dq q (quit reverting this file) responses. If a file is in modified status, individual patches derived from the modified file content can be reverted. Files in added or deleted status may only be reverted in their entirety. .It Fl R Permit recursion into directories.

If no .Ar path is specified, commit all changes in the work tree. Otherwise, commit changes at or within the specified paths. .Pp If changes have been explicitly staged for commit with .Cm got stage , only commit staged changes and reject any specified paths which have not been staged. .Pp .Cm got commit opens a temporary file in an editor where a log message can be written unless the .Fl m option is used or the .Fl F and .Fl N options are used together. Quitting the editor without saving the file will abort the commit operation. .Pp Show the status of each affected file, using the following status codes: .Bl -column YXZ description .It M Ta modified file .It D Ta file was deleted .It A Ta new file was added .It m Ta modified file modes (executable bit only) .El .Pp Files which are not part of the new commit will retain their previously recorded base commit. Some .Nm commands may refuse to run while the work tree contains files from multiple base commits. The base commit of such a work tree can be made consistent by running .Cm got update across the entire work tree. .Pp The .Cm got commit command requires the .Ev GOT_AUTHOR environment variable to be set, unless an author has been configured in .Xr got.conf 5 or Git's .Dv user.name and .Dv user.email configuration settings can be obtained from the repository's .Pa .git/config file or from Git's global .Pa ~/.gitconfig configuration file. .Pp The options for .Cm got commit are as follows: .Bl -tag -width Ds .It Fl A Ar author Set author information in the newly created commit to .Ar author . This is useful when committing changes on behalf of someone else. The .Ar author argument must use the same format as the .Ev GOT_AUTHOR environment variable. .Pp In addition to storing author information, the newly created commit object will retain .Dq committer information which is obtained, as usual, from the .Ev GOT_AUTHOR environment variable, or .Xr got.conf 5 , or Git configuration settings. .It Fl C Allow committing files in conflicted status. .Pp Committing files with conflict markers should generally be avoided. Cases where conflict markers must be stored in the repository for some legitimate reason should be very rare. There are usually ways to avoid storing conflict markers verbatim by applying appropriate programming tricks. .It Fl F Ar path Use the prepared log message stored in the file found at .Ar path when creating the new commit. .Cm got commit opens a temporary file in an editor where the prepared log message can be reviewed and edited further if needed. Cannot be used together with the .Fl m option. .It Fl m Ar message Use the specified log message when creating the new commit. Cannot be used together with the .Fl F option. .It Fl i Ar identity-file Specify an .Ar identity-file , containing a private SSH key, to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl J Ar jumphost Specify a .Ar jumphost to use with SSH connections. The same option will be passed to .Xr ssh 1 . .It Fl N This option prevents .Cm got commit from opening the commit message in an editor. It has no effect unless it is used together with the .Fl F option and is intended for non-interactive use such as scripting. .It Fl n This option prevents .Cm got commit from generating a diff of the to-be-committed changes in a temporary file which can be viewed while editing a commit message. .It Fl S Allow the addition of symbolic links which point outside of the path space that is under version control. By default, .Cm got commit will reject such symbolic links due to safety concerns. As a precaution, .Nm may decide to represent such a symbolic link as a regular file which contains the link's target path, rather than creating an actual symbolic link which points outside of the work tree. Use of this option is discouraged because external mechanisms such as .Dq make obj are better suited for managing symbolic links to paths not under version control. .El .Pp .Cm got commit will refuse to run if certain preconditions are not met. If the work tree's current branch is not in the .Dq refs/heads/ reference namespace, new commits may not be created on this branch. Local changes may only be committed if they are based on file content found in the most recent commit on the work tree's branch. If a path is found to be out of date, .Cm got update must be used first in order to merge local changes with changes made in the repository. .Tg cy .It Xo .Cm cherrypick .Op Fl lX .Op Ar commit .Xc .Dl Pq alias: Cm cy Merge changes from a single .Ar commit into the work tree.

The patterns are matched according to .Xr glob 7 rules, with extensions to improve compatibility with .Xr cvs 1 and .Xr git 1 . Patterns from each .Pa .cvsignore or .Pa .gitignore file are matched relative to the directory containing that file. If a pattern begins with two asterisks followed by a slash, .Dq **/ , the remainder of the pattern will match at any directory at or below the directory containing .Pa .cvsignore or .Pa gitignore file. Two asterisks surrounded by slashes, .Dq /**/ , in the middle of a pattern will match one directory or more. Patterns which end with a slash, .Dq / , will only match directories, and any paths below matching directories will be ignored. .Pp Unlike .Xr cvs 1 , .Nm only supports a single ignore pattern per line. Unlike .Xr git 1 , .Nm does not support negated ignore patterns prefixed with .Dq \&! , and does not match patterns at arbitrary depth relative to the .Pa .gitignore file unless they begin with .Dq **/ . For better .Xr git 1 compatibility, patterns beginning with a slash are matched as if the slash were not present. .Sh ENVIRONMENT .Bl -tag -width GOT_IGNORE_GITCONFIG .It Ev GOT_AUTHOR The author's name and email address, such as .Dq An Flan Hacker Aq Mt flan_hacker@openbsd.org .

Local changes in the work tree will be preserved and merged if necessary: .Pp .Dl $ got update -b unified-buffer-cache .Pp Create a new commit from local changes in a work tree directory.

The patch can be mailed out for review and applied to .Ox Ns 's CVS tree: .Pp .Dl $ got diff master unified-buffer-cache > /tmp/ubc.diff .Pp Edit the entire commit history of the .Dq unified-buffer-cache branch: .Pp .Dl $ got update -b unified-buffer-cache .Dl $ got update -c master .Dl $ got histedit .Pp Before working against existing branches in a repository cloned with .Cm git clone --bare instead of .Cm got clone , a Git .Dq refspec must be configured to map all references in the remote repository into the .Dq refs/remotes namespace of the local repository. This can be achieved by setting Git's .Pa remote.origin.fetch configuration variable to the value .Dq +refs/heads/*:refs/remotes/origin/* with the .Cm git config command: .Pp .Dl $ cd /var/git/repo .Dl $ git config remote.origin.fetch '+refs/heads/*:refs/remotes/origin/*' .Pp Additionally, the .Dq mirror option must be disabled: .Pp .Dl $ cd /var/git/repo .Dl $ git config remote.origin.mirror false .Pp Alternatively, the following .Xr git-fetch 1 configuration item can be added manually to the Git repository's .Pa config file: .Pp .Dl [remote \&"origin\&"] .Dl url = ... .Dl fetch = +refs/heads/*:refs/remotes/origin/* .Dl mirror = false .Pp This configuration leaves the local repository's .Dq refs/heads namespace free for use by local branches checked out with .Cm got checkout and, if needed, created with .Cm got branch . Branches in the .Dq refs/remotes/origin namespace can now be updated with incoming changes from the remote repository with .Cm got fetch or .Xr git-fetch 1 without extra command line arguments. Newly fetched changes can be examined with .Cm got log . .Pp Display changes on the remote repository's version of the .Dq master branch, as of the last time .Cm got fetch was run: .Pp .Dl $ got log -c origin/master | less .Pp As shown here, most commands accept abbreviated reference names such as .Dq origin/master instead of .Dq refs/remotes/origin/master . The latter is only needed in case of ambiguity. .Pp .Cm got rebase can be used to merge changes which are visible on the .Dq origin/master branch into the .Dq master branch. This will also merge local changes, if any, with the incoming changes: .Pp .Dl $ got update -b origin/master .Dl $ got rebase master .Pp In order to make changes committed to the .Dq unified-buffer-cache visible on the .Dq master branch, the .Dq unified-buffer-cache branch can be rebased onto the .Dq master branch: .Pp .Dl $ got update -b master .Dl $ got rebase unified-buffer-cache .Pp Changes on the .Dq unified-buffer-cache branch can now be made visible on the .Dq master branch with .Cm got integrate . Because the rebase operation switched the work tree to the .Dq unified-buffer-cache branch, the work tree must be switched back to the .Dq master branch first: .Pp .Dl $ got update -b master .Dl $ got integrate unified-buffer-cache .Pp On the .Dq master branch, log messages for local changes can now be amended with .Dq OK by other developers and any other important new information: .Pp .Dl $ got update -c origin/master .Dl $ got histedit -m .Pp If the remote repository offers write access, local changes on the .Dq master branch can be sent to the remote repository with .Cm got send . Usually, .Cm got send can be run without further arguments. The arguments shown here match defaults, provided the work tree's current branch is the .Dq master branch: .Pp .Dl $ got send -b master origin .Pp If the remote repository requires the HTTPS protocol, the .Xr git-push 1 command must be used instead: .Pp .Dl $ cd /var/git/src.git .Dl $ git push origin master .Pp When making contributions to projects which use the .Dq pull request workflow, SSH protocol repository access needs to be set up first. Once an account has been created on a Git hosting site it should be possible to upload a public SSH key for repository access authentication. .Pp The .Dq pull request workflow will usually involve two remote repositories. In the real-life example below, the .Dq origin repository was forked from the .Dq upstream repository by using the Git hosting site's web interface. The .Xr got.conf 5 file in the local repository describes both remote repositories: .Bd -literal -offset indent # Jelmers's repository, which accepts pull requests remote "upstream" { server git@github.com protocol ssh repository "/jelmer/dulwich" branch { "master" } } # Stefan's fork, used as the default remote repository remote "origin" { server git@github.com protocol ssh repository "/stspdotname/dulwich" branch { "master" } } .Ed .Pp With this configuration, Stefan can create commits on .Dq refs/heads/master and send them to the .Dq origin repository by running: .Pp .Dl $ got send -b master origin .Pp The changes can now be proposed to Jelmer by opening a pull request via the Git hosting site's web interface. If Jelmer requests further changes to be made, additional commits can be created on the .Dq master branch and be added to the pull request by running .Cd got send again. .Pp If Jelmer prefers additional commits to be .Dq squashed then the following commands can be used to achieve this: .Pp .Dl $ got update -b master .Dl $ got update -c origin/master .Dl $ got histedit -f .Dl $ got send -f -b master origin .Pp In addition to reviewing the pull request in the web user interface, Jelmer can fetch the pull request's branch into his local repository and create a local branch which contains the proposed changes: .Pp .Dl $ got fetch -R refs/pull/1046/head origin .Dl $ got branch -c refs/remotes/origin/pull/1046/head pr1046 .Pp Once Jelmer has accepted the pull request, Stefan can fetch the merged changes, and possibly several other new changes, by running: .Pp .Dl $ got fetch upstream .Pp The merged changes will now be visible under the reference .Dq refs/remotes/upstream/master . The local .Dq master branch can now be rebased on top of the latest changes from upstream: .Pp .Dl $ got update -b upstream/master .Dl $ got rebase master .Pp As an alternative to .Cm got rebase , branches can be merged with .Cm got merge : .Pp .Dl $ got update -b master .Dl $ got merge upstream/master .Pp The question of whether to rebase or merge branches is philosophical. When in doubt, refer to the software project's policies set by project maintainers. .Pp As a final step, the forked repository's copy of the master branch needs to be kept in sync by sending the new changes there: .Pp .Dl $ got send -f -b master origin .Pp If multiple pull requests need to be managed in parallel, a separate branch must be created for each pull request with .Cm got branch . Each such branch can then be used as above, in place of .Dq refs/heads/master . Changes for any accepted pull requests will still appear under .Dq refs/remotes/upstream/master, regardless of which branch was used in the forked repository to create a pull request. .Sh SEE ALSO .Xr gotadmin 1 , .Xr tog 1 , .Xr git-repository 5 , .Xr got-worktree 5 , .Xr got.conf 5 , .Xr gotwebd 8 .Sh AUTHORS .An Anthony J.

The repository format is described in .Xr git-repository 5 . .Pp .Nm provides global and command-specific options. Global options must precede the command name, and are as follows: .Bl -tag -width tenletters .It Fl h Display usage information and exit immediately. .It Fl V , -version Display program version and exit immediately. .El .Pp The commands for .Nm are as follows: .Bl -tag -width checkout .It Cm init Oo Fl A Ar hashing-algorithm Oc Oo Fl b Ar branch Oc Ar repository-path Create a new empty repository at the specified .Ar repository-path . .Pp After .Cm gotadmin init , the new repository must be populated before .Cm got checkout can be used. The .Cm got import command can be used to populate the new repository with data from a local directory. Alternatively, on a server running .Xr gotd 8 , the new repository can be made available to .Xr got 1 or .Xr git 1 clients by adding the repository to .Xr gotd.conf 5 and restarting .Xr gotd 8 . Clients may then clone the new repository from the server, populate the cloned repository, and then populate the new repository on the server via .Cm got send or .Cm git push . .Pp The options for .Cm gotadmin init are as follows: .Bl -tag -width Ds .It Fl A Ar hashing-algorithm Configure the repository's .Ar hashing-algorithm used for the computation of Git object IDs. Possible values are .Cm sha1 .Pq the default or .Cm sha256 . .It Fl b Ar branch Make the repository's HEAD reference point to the specified .Ar branch instead of the default branch .Dq main . .El .Pp The .Cm gotadmin init command is equivalent to .Cm got init . .It Cm info Op Fl r Ar repository-path Display information about a repository. This includes some configuration settings from .Xr got.conf 5 , the object ID hashing algorithm, and the number of objects stored in the repository, in packed or loose form, as well as the current on-disk size of these objects. .Pp The options for .Cm gotadmin info are as follows: .Bl -tag -width Ds .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Xr got 1 work tree, use the repository path associated with this work tree. .El .It Xo .Cm pack .Op Fl aDq .Op Fl r Ar repository-path .Op Fl x Ar reference .Op Ar reference ... .Xc Generate a new pack file and a corresponding pack file index. By default, add any loose objects which are reachable via any references to the generated pack file. .Pp If one or more .Ar reference arguments is specified, only add objects which are reachable via the specified references. Each .Ar reference argument may either specify a specific reference or a reference namespace, in which case all references within this namespace will be used. .Pp .Cm gotadmin pack always ignores references in the .Pa refs/got/ namespace, effectively treating such references as if they did not refer to any objects. .Pp The options for .Cm gotadmin pack are as follows: .Bl -tag -width Ds .It Fl a Add objects to the generated pack file even if they are already packed in a different pack file. Unless this option is specified, only loose objects will be added. .It Fl D Force the use of ref-delta representation for deltified objects. If this option is not specified, offset-deltas will be used to represent deltified objects. .It Fl q Suppress progress reporting output. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Xr got 1 work tree, use the repository path associated with this work tree. .It Fl x Ar reference Exclude objects reachable via the specified .Ar reference from the pack file. The .Ar reference argument may either specify a specific reference or a reference namespace, in which case all references within this namespace will be excluded. The .Fl x option may be specified multiple times to build a list of references to exclude. .Pp Exclusion takes precedence over inclusion. If a reference appears in both the included and excluded lists, it will be excluded. .El .Tg ix .It Cm indexpack Ar packfile-path .Dl Pq alias: Cm ix Create a pack index for the pack file at .Ar packfile-path . .Pp A pack index is required for using the corresponding pack file with .Xr got 1 . Usually, a pack index will be created by commands such as .Cm gotadmin pack or .Cm got fetch as part of regular operation. The .Cm gotadmin indexpack command may be used to recover from a corrupt or missing index. A given pack file will always yield the same bit-identical index. .Pp The provided .Ar packfile-path must be located within the .Pa objects/pack/ directory of the repository and should end in .Pa .pack . The filename of the corresponding pack index is equivalent, except that it ends in .Pa .idx . .Tg ls .It Xo .Cm listpack .Op Fl hs .Ar packfile-path .Xc .Dl Pq alias: Cm ls List the contents of the pack file at .Ar packfile-path . .Pp Each object contained in the pack file will be displayed on a single line. The information shown includes the object ID, object type, object offset, and object size. .Pp If a packed object is deltified against another object, the delta base will be shown as well. For offset deltas, the delta base is identified via an offset into the pack file. For reference deltas, the delta base is identified via an object ID. .Pp The provided .Ar packfile-path must be located within the .Pa objects/pack/ directory of the repository and should end in .Pa .pack . The corresponding pack index must exist and can be created with .Cm gotadmin indexpack if it is missing. .Pp The options for .Cm gotadmin listpack are as follows: .Bl -tag -width Ds .It Fl h Show object sizes in human-readable form. .It Fl s Display statistics about the pack file after listing objects. This includes the total number of objects stored in the pack file and a break-down of the number of objects per object type. .El .Tg cl .It Xo .Cm cleanup .Op Fl anpq .Op Fl r Ar repository-path .Xc .Dl Pq alias: Cm cl Repack the repository and then purge unreferenced loose objects and redundant pack files. Display the amount of disk space which has been freed as a result. .Pp Unreferenced objects are present in the repository but cannot be reached via any reference in the entire .Pa refs/ namespace. Objects will usually become unreferenced as a result of deleting branches, tags, or other references with .Cm got branch -d , .Cm got ref -d , or .Cm got fetch -X . .Pp Loose objects are stored as individual files in subdirectories of the repository's .Pa objects/ directory. .Pp Packed objects are stored in pack files under .Pa objects/pack/ . .Pp If redundant copies of packed objects exist in loose form, such redundant copies will be purged. If all the objects of a pack file are present in a bigger pack file, the redundant smaller pack file will be purged. .Pp References in the .Pa refs/got namespace may prevent objects from being purged. This includes references in the .Pa refs/got/worktree namespace created by .Cm got checkout and .Cm got update , as well as references in the .Pa refs/got/backup namespace created by .Cm got rebase and .Cm got histedit . .Cm gotadmin cleanup will only purge corresponding objects once such references have been deleted with .Cm got rebase -X , .Cm got histedit -X , or .Cm got ref -d . .Pp The .Dq preciousObjects Git extension is intended to prevent the removal of objects from a repository. .Cm gotadmin cleanup will refuse to operate on repositories where this extension is active. .Pp For compatibility with Git, if a file with the extension .Pa .keep exists and corresponds to a pack file with the extension .Pa .pack then this pack file will not be removed. .Pp Some Git repositories contain pack index files which lack a corresponding pack file, which is an inconsistent repository state. In such cases, .Cm gotadmin cleanup -p -n will display a list of affected pack index files. Whenever possible, the missing pack files should be restored. If restoring missing pack files is not possible, then affected pack index files can be removed with .Cm gotadmin cleanup -p . .Pp The options for .Cm gotadmin cleanup are as follows: .Bl -tag -width Ds .It Fl a Delete all redundant loose and packed objects. By default, objects which are newer than an implementation-defined modification timestamp are kept on disk to prevent race conditions with other commands that add new objects to the repository while .Cm gotadmin cleanup is running. .It Fl n Display the usual progress output and summary information but do not actually remove any files from disk. .It Fl p Instead of purging unreferenced loose objects and redundant pack files, remove any pack index files which do not have a corresponding pack file. .It Fl q Suppress progress reporting and disk space summary output. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Xr got 1 work tree, use the repository path associated with this work tree. .El .It Xo .Cm dump .Op Fl q .Op Fl r Ar repository-path .Op Fl x Ar reference .Op Ar reference ... .Xc Dump the contents of the repository to standard output in Git bundle format. .Pp If one or more .Ar reference arguments is specified, only add objects which are reachable via the specified references. Each .Ar reference argument may either specify a specific reference or a reference namespace, in which case all references within this namespace will be used. .Pp The options for .Nm .Cm dump are as follows: .Bl -tag -width Ds .It Fl q Suppress progress reporting output. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Xr got 1 work tree, use the repository path associated with this work tree. .It Fl x Ar reference Exclude objects reachable via the specified .Ar reference from the bundle. The .Ar reference argument may either specify a specific reference or a reference namespace, in which case all references within this namespace will be excluded. The .Fl x option may be specified multiple times to build a list of references to exclude. .Pp Exclusion takes precedence over inclusion. If a reference appears in both the included and excluded lists, it will be excluded. .El .It Xo .Cm load .Op Fl nq .Op Fl l Ar bundle-path .Op Fl r Ar repository-path .Op Ar reference ... .Xc Read a Git bundle stream from standard input and load its data into a repository. .Pp If one or more .Ar reference arguments are provided then only load the specified references from the bundle. Otherwise, all references will be loaded. .Pp The options for .Cm gotadmin load are as follows: .Bl -tag -width Ds .It Fl l Ar bundle-path List references available for loading from the bundle at the specified .Ar bundle-path and exit immediately. If the .Fl l option is specified then no .Ar reference arguments are allowed. The .Fl l option is incompatible with the .Fl n option. .It Fl n Attempt to load the bundle but don't install new packfile or update any reference. Can be used to verify the integrity of the bundle. .It Fl q Suppress progress reporting output. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Xr got 1 work tree, use the repository path associated with this work tree. .El .El .Sh EXIT STATUS .Ex -std gotadmin .Sh SEE ALSO .Xr got 1 , .Xr tog 1 , .Xr git-repository 5 , .Xr got.conf 5 .Sh AUTHORS .An Christian Weisgerber Aq Mt naddy@openbsd.org .An Josh Rickmar Aq Mt jrick@zettaport.com .An Klemens Nanni Aq Mt kn@openbsd.org .An Omar Polo Aq Mt op@openbsd.org .An Ori Bernstein Aq Mt ori@openbsd.org .An Stefan Sperling Aq Mt stsp@openbsd.org .An Tracey Emery Aq Mt tracey@traceyemery.net .Sh CAVEATS .Nm is a work-in-progress and some features remain to be implemented. .Pp At present, the user has to fall back on .Xr git 1 to perform some tasks.

This file must be owned by the root user and must not be readable by any other users. .Pp The file format is line-based, with one entry per line. Comments can appear at the start of a line using a hash mark .Pq Sq # , and extend to the end of the line. Empty lines are ignored. .Pp Each entry consists of whitespace-separated tokens and defines a set of credentials. Any credential parameters containing whitespace should be surrounded by single or double quotes. .Pp Each set of credentials must be given a .Ar label which can be used to refer to credentials in .Xr gotd.conf 5 . This .Ar label must be unique among all credentials of the same type. .Pp The supported credential types and their parameters are: .Bl -tag -width Ds .It Ic auth Ar label Ic user Ar user Ic password Ar password The .Ic auth type represents HTTP Basic Authentication credentials consisting of a .Ar user and a .Ar password . .It Ic hmac Ar label Ar secret The .Ic hmac type represents shared secrets for use with HMAC signatures of HTTP request bodies. A suitable .Ar secret can be generated with .Xr openssl 1 as follows: .Pp .Dl $ openssl rand -base64 32 .El .Pp .Sh FILES .Bl -tag -width Ds -compact .It Pa /etc/gotd-secrets.conf Location of the .Nm configuration file. .El .Sh EXAMPLES Define credentials for HTTP basic authentication and HMAC signatures: .Bd -literal -offset indent # /etc/gotd-secrets.conf auth mochi user "flan" password "super-strong-password!" hmac hacker q0tcl8QhjYs7U75MW/2rwB30CpdbAhONkfLGxFHm/+8= .Ed .Pp These credentials can be referenced in .Xr gotd.conf 5 as follows: .Bd -literal -offset indent # /etc/gotd.conf repository "openbsd/src" { path "/var/git/src.git" permit rw :hackers notify { url https://example.com/ci/ auth mochi hmac hacker } } .El .Sh SEE ALSO .Xr got 1 , .Xr gotsh 1 , .Xr gotd.conf 5 , .Xr gotd 8 got-portable-0.119/gotd/session_write.c0000664000175000017500000015701115066536113013617 /* * Copyright (c) 2022, 2023 Stefan Sperling * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

Comments can be put anywhere in the file using a hash mark .Pq Sq # , and extend to the end of the current line. Arguments names not beginning with a letter, digit or underscore, as well as reserved words .Pq such as Ic listen , Ic repository No or Ic user , must be quoted. Arguments containing whitespace should be surrounded by double quotes .Pq \&" . .Pp Macros can be defined that are later expanded in context. Macro names must start with a letter, digit, or underscore, and may contain any of those characters, but may not be reserved words. Macros are not expanded inside quotes. For example: .Bd -literal -offset indent path = "/var/run/gotd.sock" listen on $path .Ed .Sh GLOBAL CONFIGURATION The available global configuration directives are as follows: .Bl -tag -width Ds .It Ic connection Ar option Set the specified options and limits for connections to the .Xr gotd 8 unix socket. .Pp The .Ic connection directive may be specified multiple times, and multiple .Ar option arguments may be specified within curly braces: .Pp .Ic connection Brq Ar ... .Pp Each option should only be specified once. If a given option is listed multiple times, the last line which sets this option wins. .Pp Valid connection options are: .Bl -tag -width Ds .It Ic request timeout Ar seconds Specify the inactivity timeout for operations between client and server. If this timeout is exceeded while a Git protocol request is being processed, the request will be aborted and the connection will be terminated. .Pp The timeout value may also have a suffix indicating its unit of measure. Supported suffixes are: .Pp .Bl -tag -compact -width tenletters .It Ar s No or Ar S seconds .It Ar m No or Ar M minutes .It Ar h No or Ar H hours .El .Pp The default timeout is 1h (3600 seconds, one hour). This should only be changed if legitimate requests are exceeding the default timeout for some reason, such as the server spending an extraordinary amount of time generating a pack file. .It Ic limit Ic user Ar identity Ar number Limit the maximum amount of concurrent connections by the user with the username .Ar identity to .Ar number . Numeric user IDs are also accepted. .Pp The default per-user limit is 4. This should only be changed if concurrent connections from a given user are expected to exceed the default limit, for example if an anonymous user is granted read access and many concurrent connections will share this anonymous user identity. .El .It Ic listen on Ar path Set the path to the unix socket which .Xr gotd 8 should listen on. If not specified, the path .Pa /var/run/gotd.sock will be used. .It Ic user Ar user Set the .Ar user which will run .Xr gotd 8 . Initially, .Xr gotd 8 requires root privileges in order to create its unix socket. Afterwards, .Xr gotd 8 drops privileges to the specified .Ar user . If not specified, the user _gotd will be used. Numeric user IDs are also accepted. .El .Sh REPOSITORY CONFIGURATION At least one repository context must exist for .Xr gotd 8 to function. For each repository, access rules must be configured using the .Ic permit and .Ic deny configuration directives. Multiple access rules can be specified, and the last matching rule determines the action taken. If no rule matches, access to the repository is denied. .Pp A repository context is declared with a unique .Ar name , followed by repository-specific configuration directives inside curly braces: .Pp .Ic repository Ar name Brq ... .Pp .Xr got 1 and .Xr git 1 clients can connect to a repository by including the repository's unique .Ar name in the request URL. Clients appending the string .Dq .git to the .Ar name will also be accepted. .Pp If desired, the .Ar name may contain path-separators, .Dq / , to expose repositories as part of a virtual client-visible directory hierarchy. .Pp The available repository configuration directives are as follows: .Bl -tag -width Ds .It Ic deny Ar identity Deny repository access to users with the username .Ar identity . Group names may be matched by prepending a colon .Pq Sq \&: to .Ar identity . Numeric IDs are also accepted. .It Ic path Ar path Set the path to the Git repository. Must be specified. .It Ic permit Ar mode Ar identity Permit repository access to users with the username .Ar identity . The .Ar mode argument must be set to either .Ic ro for read-only access, or .Ic rw for read-write access. Group names may be matched by prepending a colon .Pq Sq \&: to .Ar identity . Numeric IDs are also accepted. .It Ic protect Brq Ar ... The .Cm protect directive may be used to protect branches and tags in a repository from being overwritten by potentially destructive client-side commands, such as when .Cm got send -f and .Cm git push -f are used to change the history of a branch. .Pp To build a set of protected branches and tags, multiple .Ic protect directives may be specified per repository and multiple .Ic protect directive parameters may be specified within curly braces. .Pp The available .Cm protect parameters are as follows: .Bl -tag -width Ds .It Ic branch Ar name Protect the named branch. The branch may be created if it does not exist yet. Attempts to delete the branch or change its history will be denied. .Pp If the .Ar name does not already begin with .Dq refs/heads/ it will be looked up in the .Dq refs/heads/ reference namespace. .It Ic branch Ic namespace Ar namespace Protect the given reference namespace, assuming that references in this namespace represent branches. New branches may be created in the namespace. Attempts to change the history of branches or delete them will be denied. .Pp The .Ar namespace argument must be absolute, starting with .Dq refs/ . .It Ic tag Ic namespace Ar namespace Protect the given reference namespace, assuming that references in this namespace represent tags. New tags may be created in the namespace. Attempts to change or delete existing tags will be denied. .Pp The .Ar namespace argument must be absolute, starting with .Dq refs/ . .El .Pp The special reference namespaces .Dq refs/got/ and .Dq refs/remotes/ do not need to be listed in .Nm . These namespaces are always protected and even attempts to create new references in these namespaces will always be denied. .It Ic notify Brq Ar ... The .Ic notify directive enables notifications about new commits or tags added to the repository. .Pp Notifications via email require an SMTP daemon which accepts mail for forwarding without requiring client authentication or encryption. On .Ox the .Xr smtpd 8 daemon can be used for this purpose. The default content of email notifications looks similar to the output of the .Cm got log -d command. .Pp Notifications via HTTP require a HTTP or HTTPS server which is accepting POST requests with or without HTTP Basic authentication. Depending on the use case a custom server-side CGI script may be required for the processing of notifications. HTTP notifications can achieve functionality similar to Git's server-side post-receive hook script with .Xr gotd 8 by triggering arbitrary post-commit actions via the HTTP server. .Pp The .Ic notify directive expects parameters which must be enclosed in curly braces. The available parameters are as follows: .Bl -tag -width Ds .It Ic branch Ar name Send notifications about commits to the named branch. The .Ar name will be looked up in the .Dq refs/heads/ reference namespace. This directive may be specified multiple times to build a list of branches to send notifications for. If neither a .Ic branch nor a .Ic reference namespace are specified then changes to any reference will trigger notifications. .It Ic reference Ic namespace Ar namespace Send notifications about commits or tags within a reference namespace. This directive may be specified multiple times to build a list of namespaces to send notifications for. If neither a .Ic branch nor a .Ic reference namespace are specified then changes to any reference will trigger notifications. .It Ic email Oo Ic from Ar sender Oc Ic to Ar recipient Oo Ic reply to Ar responder Oc Oo Ic relay Ar hostname Oo Ic port Ar port Oc Oc Send notifications via email to the specified .Ar recipient . This directive may be specified multiple times to build a list of recipients to send notifications to. .Pp The .Ar recipient must be an email addresses that accepts mail. The .Ar sender will be used as the From address. If not specified, the sender defaults to an email address composed of the user account running .Xr gotd 8 and the local hostname. .Pp If a .Ar responder is specified via the .Ic reply to directive, the .Ar responder will be used as the Reply-to address. Setting the Reply-to header can be useful if replies should go to a mailing list instead of the .Ar sender , for example. .Pp By default, mail will be sent to the SMTP server listening on the loopback address 127.0.0.1 on port 25. The .Ic relay and .Ic port directives can be used to specify a different SMTP server address and port. .It Ic url Ar URL Oo Ic auth Ar label Oo Ic insecure Oc Oc Oo Ic hmac Ar label Oc Send notifications via HTTP. This directive may be specified multiple times to build a list of HTTP servers to send notifications to. .Pp The notification will be sent as a POST request to the given .Ar URL , which must be a valid HTTP URL and begin with either .Dq http:// or .Dq https:// . If HTTPS is used, sending of notifications will only succeed if no TLS errors occur. .Pp The optional .Ic auth directive enables HTTP Basic authentication. Authentication credentials must be specified in the separate .Xr gotd-secrets.conf 5 file, using the .Ar label as identifier. Unless the .Ic insecure option is specified the notification target .Ar URL must be a .Dq https:// URL to avoid leaking of authentication credentials. .Pp If a .Ic hmac secret is provided, the request body will be signed using HMAC, allowing the receiver to verify the notification message's authenticity and integrity. The HMAC secret to use must be specified in the separate .Xr gotd-secrets.conf 5 file, using the .Ar label as identifier. The signature uses HMAC-SHA256 and will be sent in the HTTP header .Dq X-Gotd-Signature . .Pp The request body contains a JSON object with a .Dq notifications property containing an array of notification objects. The following notification object properties are always present: .Bl -tag -width authenticated_user .It Dv repo The repository name as a string. .It Dv authenticated_user The committer's user account as authenticated by .Xr gotd 8 as a string. .It Dv type The notification object type as a string. .El .Pp Each notification object carries additional type-specific properties. The types and their type-specific properties are: .Bl -tag -width Ds .It Dv commit The commit notification object has the following fields. Except where noted, all are optional. .Bl -tag -width Ds .It Dv short Boolean, indicates whether the object has all the fields set. When several commits are batched in a single send operation, not all of the fields are available for each commit object. .It Dv id The commit ID as string, may be abbreviated. .It Dv committer An object with the committer information with the following fields: .Pp .Bl -tag -compact -width Ds .It Dv full Committer's full name. .It Dv name Committer's name. .It Dv mail Committer's mail address. .It Dv user Committer's username. This is the only field guaranteed to be set. .El .It Dv author An object with the author information. Has the same fields as the .Sq committer but may be unset. .It Dv date Number, representing the number of seconds since the Epoch in UTC. .It Dv short_message The first line of the commit message. This field is always set. .It Dv message The complete commit message, may be unset. .It Dv diffstat An object with the summarized changes, may be unset. Contains a .Sq files field with an array of objects describing the changes per-file and a .Sq total field with the cumulative changes.

The configuration file format is described in .Xr gotd.conf 5 . .Pp It is recommended to restrict .Xr ssh 1 features available to users of .Nm . See .Xr gotsh 1 for details. .Pp The options for .Nm are as follows: .Bl -tag -width Ds .It Fl d Do not daemonize. Send log output to stderr. .It Fl f Ar config-file Set the path to the configuration file. If not specified, the file .Pa /etc/gotd.conf will be used. .It Fl n Configtest mode. Only check the configuration file for validity. .It Fl s Ar secrets Set the path to the secrets file. If not specified, the file .Pa /etc/gotd-secrets.conf will be used if it exists. .It Fl v Verbose mode. Verbosity increases if this option is used multiple times. .El .Sh FILES .Bl -tag -width Ds -compact .It Pa /etc/gotd.conf Default location of the configuration file. .It Pa /var/run/gotd.sock Default location of the unix socket which .Nm is listening on. This path can be configured in .Xr gotd.conf 5 . .El .Sh EXAMPLES Create an empty repository to be served by .Nm , ensuring that it can only be accessed by the _gotd user: .Pp .Dl # mkdir -p /git/myrepo.git .Dl # chmod 700 /git/myrepo.git .Dl # chown _gotd /git/myrepo.git .Dl # su -m _gotd -c 'gotadmin init /git/myrepo.git' .Pp Add the new repository to .Xr gotd.conf 5 granting read-write access to the flan_hacker user account, and restart .Nm : .Pp .Dl # cat >> /etc/gotd.conf < inclusion * portable: portably wrap socket functions between BSDs/Linux * portable: improve homebrew support for MacOS # got-portable 0.74 (2022-07-14) * portable: made the 'date' command more portable in the test suite. * portable: improved error-handling for commands on BSD-systems without coreutils being installed. * portable: reworked how 'sed' is wrapped portably, so that it now doesn't use any bashisms, and will therefore run under strict POSIX-sh (dash on Ubuntu, for instance). # got-portable 0.73 (2022-07-04) * Changes as found in got-0.73. * portable: the libexec helpers now support Capsicum on FreeBSD, which is similar to OpenBSD's pledge() syscall. * Some portable work has taken place, but these have been merged upstream and hence will be in the got-0.73 changes file. # got-portable 0.71 (2022-06-23) * portable: fix cross-compilation, from Leah Neukirchen # got-portable 0.70 (2022-05-13) * Changes from got-0.70; no -portable specific changes worth mentioning. # got-portable 0.69 (2022-04-24) * portable: added Apline Linux to the core set of OSes when checking CI/CD - this therefore implies -portable can build on muscl as well as glibc. * portable: fixed compilation of -portable on Alpine Linux with respect to Landlock by using the correct header file. * portable: added SipHash as a -portable implementation. # got-portable 0.68.1 (2022-03-22) * portable: fix up a bad merge whereby a code block that should have been removed was left in-situ. # got-portable 0.68 (2022-03-22) * Changes from got-0.68 * portable: support for the following operating systems: - FreeBSD - NetBSD - DragonFlyBSD - MacOS # got-portable 0.67; (2022-02-20) * Changes from got-0.66 * Landlock support: portable now has support for the landlock API which is similar to unveil(), allowing restrictions to which part of the filesystem a process can access. # got-portable 0.66; (2022-01-12) * Changes from got-0.65 # got-portable 0.65; (2022-01-06) * Added timespec*() compat-wrappers for BSD-time functions. # got-portable 0.64; (2021-11-24) * regress: make tests POSIX-compliant by making them run under dash (Ubuntu) # got-portable 0.62; (2021-10-17) * Changes from got-0.62 # got-portable 0.61; (2021-10-09) * Port regress tests. * Improve FreeBSD compatibility. # got-portable 0.60; (2021-09-21) * First portable version released for Linux. got-portable-0.119/tog/0000775000175000017500000000000015066537276010500 5got-portable-0.119/tog/tog.c0000664000175000017500000106221615066536114011353 /* * Copyright (c) 2018, 2019, 2020 Stefan Sperling * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

This repository format is described in .Xr git-repository 5 . .Pp .Nm supports several types of views which display repository data: .Bl -tag -width Ds .It Log view Displays commits in the repository's history. This view is displayed initially if no .Ar command is specified, or if just a .Ar path is specified. .It Diff view Displays work tree changes or changes made in a particular commit. .It Blame view Displays the line-by-line history of a file. .It Tree view Displays the tree corresponding to a particular commit. .It Ref view Displays references in the repository. .El .Pp .Nm provides global and command-specific key bindings and options. Some command-specific key bindings may be prefixed with an integer, which is denoted by N in the descriptions below, and is used as a modifier to the operation as indicated. .Nm will echo digits to the screen when count modifiers are entered, and complete the sequence upon input of the first non-numeric character. Count modifiers can be aborted by entering an unmapped key. Once a compound command is executed, the operation can be cancelled with .Cm C-g or .Cm Backspace . .Pp Global options must precede the command name, and are as follows: .Bl -tag -width tenletters .It Fl h Display usage information. .It Fl V , -version Display program version and exit immediately. .El .Pp The global key bindings are: .Bl -tag -width Ds .It Cm H, F1 Display run-time help. Key bindings for the focussed view will be displayed. Pressing this again inside the help view will toggle the display of key bindings for all .Nm views. .It Cm Q Quit .Nm . .It Cm q Quit the view which is in focus. .It Cm Tab Switch focus between views. .It Cm F Toggle fullscreen mode for a split-screen view. .Nm will automatically use vertical split-screen views if the size of the terminal window is sufficiently large. .It Cm S Switch the current split-screen layout, and render all active views in this new layout. The split-screen layout can be either vertical or horizontal. If the terminal is not wide enough when switching to a vertical split, views will render in fullscreen. .It Cm - When in a split-screen view, decrease the size of the focussed split N increments (default: 1). .It Cm + When in a split-screen view, increase the size of the focussed split N increments (default: 1). .It Cm G Go to line N in the view (default: last line). .It Cm g Go to line N in the view (default: first line). .It Cm Right-arrow, l Scroll view to the right N increments (default: 1). .br Output moves left on the screen. .It Cm Left-arrow, h Scroll view to the left N increments (default: 1). .br Output moves right on the screen. .It Cm $ Scroll view to the rightmost position. .It Cm 0 Scroll view left to the start of the line. .El .Pp The commands for .Nm are as follows: .Bl -tag -width blame .It Xo .Cm log .Op Fl b .Op Fl c Ar commit .Op Fl r Ar repository-path .Op Ar path .Xc Display history of a repository. If a .Ar path is specified, show only commits which modified this path. If invoked in a work tree, the .Ar path is interpreted relative to the current working directory, and the work tree's path prefix is implicitly prepended. Otherwise, the path is interpreted relative to the repository root. .Pp If invoked in a work tree, the log entry of the work tree's base commit will be prefixed with one of the following annotations: .Bl -column YXZ description .It * Ta work tree's base commit and the base commit of all tracked files matches the branch tip .It \(a~ Ta work tree comprises mixed commits or its base commit is out-of-date .El .Pp This command is also executed if no explicit command is specified. .Pp The key bindings for .Cm tog log are as follows (N denotes optional prefixed count modifier): .Bl -tag -width Ds .It Cm Down-arrow, j, >, Full stop, Ctrl-n Move the selection cursor down N lines (default: 1). .It Cm Up-arrow, k, <, Comma, Ctrl-p Move the selection cursor up N lines (default: 1). .It Cm Page-down, Space, Ctrl+f, f Move the selection cursor down N pages (default: 1). .It Cm Page-up, Ctrl+b, b Move the selection cursor up N pages (default: 1). .It Cm Ctrl+d, d Move the selection cursor down N half pages (default: 1). .It Cm Ctrl+u, u Move the selection cursor up N half pages (default: 1). .It Cm Home, = Move the cursor to the newest commit. .It Cm End, * Move the cursor to the oldest commit. This will traverse all commits on the current branch which may take a long time depending on the number of commits in branch history. If needed, this operation can be cancelled with .Cm C-g or .Cm Backspace . .It Cm g Move the cursor to commit N (default: 1). .It Cm G Like .Cm g but defaults to the oldest commit. .It Cm Enter Open a .Cm diff view showing file changes made in the currently selected commit. If a commit is marked with the .Cm m key map, open a diff view showing file changes made between the marked commit and the currently selected commit. .It Cm m Mark or unmark the selected commit. When a commit is marked, pressing the .Cm enter key on another selected commit opens a .Cm diff view showing the changes between the marked commit and the currently selected commit. .It Cm T Open a .Cm tree view showing the tree for the currently selected commit. .It Cm Backspace Show log entries for the parent directory of the currently selected path. However when an active search is in progress or when additional commits are loaded, .Cm Backspace aborts the running operation. .It Cm / Prompt for a search pattern and start searching for matching commits. The search pattern is an extended regular expression which is matched against a commit's author name, committer name, log message, and commit ID. Regular expression syntax is documented in .Xr re_format 7 . .It Cm & Prompt for a pattern and limit the log view's list of commits to those which match the pattern. If no pattern is specified, i.e. the .Cm & prompt is immediately closed with the Enter key, then the pattern is cleared. Until the pattern is cleared, the limited list of commits replaces the full list of commits for all operations supported by the log view. For example, a search started with .Cm / will search the limited list of commits, rather than searching all commits. The pattern is an extended regular expression which is matched against a commit's author name, committer name, log message, and commit ID. Regular expression syntax is documented in .Xr re_format 7 . .It Cm n Find the Nth next commit which matches the current search pattern (default: 1). .br Searching continues until either a match is found or .Cm C-g or the .Cm Backspace key is pressed. .It Cm N Find the Nth previous commit which matches the current search pattern (default: 1). .br Searching continues until either a match is found or .Cm C-g or the .Cm Backspace key is pressed. .It Cm Ctrl+l Reload the .Cm log view with new commits found in the repository or new work tree changes. .It Cm B Reload the .Cm log view and toggle display of merged commits. The .Fl b option determines whether merged commits are displayed initially. .It Cm R Open a .Cm ref view listing all references in the repository. This can then be used to open a new .Cm log view for arbitrary branches and tags. .It Cm @ Toggle between showing the committer name and the author name. .El .Pp The options for .Cm tog log are as follows: .Bl -tag -width Ds .It Fl b Display individual commits which were merged into the current branch from other branches. By default, .Cm tog log shows the linear history of the current branch only. The .Cm B key binding can be used to toggle display of merged commits at run-time. .It Fl c Ar commit Start traversing history at the specified .Ar commit . The expected argument is a commit ID, or a reference name or keyword which will be resolved to a commit ID. An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, .Sy :head:-2 denotes the work tree branch head's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy foobar:+3 will denote the 3rd generation descendant of the commit resolved by the .Qq foobar reference. A .Qq :+ or .Qq :- modifier without a trailing integer has an implicit .Qq 1 appended .Po e.g., .Sy :base:+ is equivalent to .Sy :base:+1 .Pc . .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Xr got 1 work tree, use the repository path associated with this work tree. .El .It Xo .Cm diff .Op Fl asw .Op Fl C Ar number .Op Fl c Ar commit .Op Fl r Ar repository-path .Op Ar object1 Ar object2 | Ar path ... .Xc If invoked within a work tree without any arguments, display all local changes in the work tree. If one or more .Ar path arguments are specified, only show changes within the specified paths. .Pp Alternatively, if two object arguments are specified, display the differences between the two objects in the repository. Treat each of the two arguments as a reference, a tag name, an object ID, or a keyword and display differences between the corresponding objects. Both objects must be of the same type (blobs, trees, or commits). An abbreviated hash argument will be expanded to a full commit ID automatically, provided the abbreviation is unique. The keywords .Qq :base and .Qq :head resolve to the work tree's base commit and branch head, respectively. The former is only valid if invoked in a work tree, while the latter will resolve to the tip of the work tree's current branch if invoked in a work tree, otherwise it will resolve to the repository's HEAD reference. Keywords and references may be appended with .Qq :+ or .Qq :- modifiers and an optional integer N to denote the Nth descendant or antecedent by first parent traversal, respectively; for example, .Sy :head:-2 denotes the work tree branch head's 2nd generation ancestor, and .Sy :base:+4 denotes the 4th generation descendant of the work tree's base commit. Similarly, .Sy foobar:+3 will denote the 3rd generation descendant of the commit resolved by the .Qq foobar reference. A .Qq :+ or .Qq :- modifier without a trailing integer has an implicit .Qq 1 appended .Po e.g., .Sy :base:+ is equivalent to .Sy :base:+1 .Pc . .Pp The key bindings for .Cm tog diff are as follows (N denotes optional prefixed count modifier): .Bl -tag -width Ds .It Cm a Toggle treatment of file contents as ASCII text even if binary data was detected. .It Cm Down-arrow, j, Ctrl-n Scroll down N lines (default: 1). .It Cm Up-arrow, k, Ctrl-p Scroll up N lines (default: 1). .It Cm Page-down, Space, Ctrl+f, f Scroll down N pages (default: 1). .It Cm Page-up, Ctrl+b, b Scroll up N pages (default: 1). .It Cm Ctrl+d, d Scroll down N half pages (default: 1). .It Cm Ctrl+u, u Scroll up N half pages (default: 1). .It Cm Home Scroll to the top of the view. .It Cm End Scroll to the bottom of the view. .It Cm g Scroll to line N (default: 1). .It Cm G Like .Cm g but defaults to the last line in the diff. .It Cm \&( Navigate to the Nth previous file in the diff (default: 1). .It Cm \&) Navigate to the Nth next file in the diff (default: 1). .It Cm \&{ Navigate to the Nth previous hunk in the diff (default: 1). .It Cm \&} Navigate to the Nth next hunk in the diff (default: 1). .It Cm \&[ Reduce diff context by N lines (default: 1). .It Cm \&] Increase diff context by N lines (default: 1). .It Cm <, Comma, K If the .Cm diff view was opened via the .Cm log view, move to the Nth previous (younger) commit. If the diff was opened via the .Cm blame view, move to the Nth previous line and load the corresponding commit (default: 1). .It Cm >, Full stop, J If the .Cm diff view was opened via the .Cm log view, move to the Nth next (older) commit. If the diff was opened via the .Cm blame view, move to the Nth next line and load the corresponding commit (default: 1). .It Cm p Write the currently viewed diff to a patch file in .Pa /tmp . The patch pathname is drawn to the status line. .It Cm / Prompt for a search pattern and start searching for matching lines. The search pattern is an extended regular expression. Regular expression syntax is documented in .Xr re_format 7 . .It Cm n Find the Nth next line which matches the current search pattern (default: 1). .It Cm N Find the Nth previous line which matches the current search pattern (default: 1). .It Cm w Toggle display of whitespace-only changes. .It Cm A Change the diff algorithm. Supported diff algorithms are Myers (quick and dirty) and Patience (slow and tidy). This is a global setting which also affects the .Cm blame view. .El .Pp The options for .Cm tog diff are as follows: .Bl -tag -width Ds .It Fl a Treat file contents as ASCII text even if binary data is detected. .It Fl C Ar number Set the number of context lines shown in the diff. By default, 3 lines of context are shown. .It Fl c Ar commit Show differences between commits in the repository. This option may be used up to two times. When used only once, show differences between the specified .Ar commit and its first parent commit. When used twice, show differences between the two specified commits. .Pp The expected argument is a commit ID hash, or an existing reference, tag name, or keyword, which is resolved to a commit ID. Unique abbreviated hash arguments are automatically expanded to a full hash. Both objects must be of the same type (i.e., blobs, trees, or commits). .Pp If the .Fl c option is used, all non-option arguments are interpreted as paths. If one or more such .Ar path arguments are provided, only show differences for the specified paths. .It Fl r Ar repository-path Use the repository at the specified path. If not specified, assume the repository is located at or above the current working directory. If this directory is a .Xr got 1 work tree, use the repository path associated with this work tree. .It Fl s Show changes staged with .Cm got stage instead of showing local changes in the work tree. This option is only valid when .Cm tog diff is invoked in a work tree with no .Fl c options. .It Fl w Ignore whitespace-only changes. .El .It Xo .Cm blame .Op Fl c Ar commit .Op Fl r Ar repository-path .Ar path .Xc Display line-by-line history of a file at the specified path. .Pp The key bindings for .Cm tog blame are as follows (N denotes optional prefixed count modifier): .Bl -tag -width Ds .It Cm Down-arrow, j, Ctrl-n Move the selection cursor down N pages (default: 1). .It Cm Up-arrow, k, Ctrl-p Move the selection cursor up N pages (default: 1). .It Cm Page-down, Space, Ctrl+f, f Move the selection cursor down N pages (default: 1). .It Cm Page-up, Ctrl+b, b Move the selection cursor up N pages (default: 1). .It Cm Ctrl+d, d Move the selection cursor down N half pages (default: 1). .It Cm Ctrl+u, u Move the selection cursor up N half pages (default: 1). .It Cm Home Move the selection cursor to the first line of the file. .It Cm End Move the selection cursor to the last line of the file. .It Cm g Move the selection cursor to line N (default: 1). .It Cm G Like .Cm g but defaults to the last line in the file. .It Cm Enter Open a .Cm diff view for the currently selected line's commit. .It Cm c Reload the .Cm blame view with the version of the file as found in the currently selected line's commit. .It Cm p Reload the .Cm blame view with the version of the file as found in the parent commit of the currently selected line's commit. .It Cm C Reload the .Cm blame view with the previously blamed commit. .It Cm L Open a .Cm log view for the currently selected annotated line. .It Cm / Prompt for a search pattern and start searching for matching lines. The search pattern is an extended regular expression.

=============== This is the portable version of got[1] (Game of Trees), using autotools to provide the library checks required for GoT's dependencies. The following operating systems are supported: * FreeBSD * NetBSD * DragonFlyBSD * MacOS * Linux DEPENDENCIES ============ Note that the names of these libraries are indicative only; the names might vary. Linux: * `libncurses` (for tog(1)) * `libbsd` (BSD's arc4random routines) * `libmd` (SHA256 routines) * `libuuid` (for UUID generation) * `libz` (for Z compression) * `pkg-config` (for searching libraries) * `bison` (for configuration file grammar) * `libevent` (for gotwebd) * `libtls` (may be known as `libretls`) FreeBSD: * `automake` * `pkgconf` * `libretls` * `libevent` (for gotwebd) NetBSD: * `automake` * `libuuid` * `ncuresesw` * `libevent` (for gotwebd) * `libretls` DragonFlyBSD: * `automake` * `pkgconf` * `openssl` * `libevent` (for gotwebd) * `libretls` Darwin (MacOS): * `automake` * `bison` * `pkg-config` * `ncurses` * `openssl` * `ossp-uuid` * `libevent` (for gotwebd) * `libretls` TESTS (REGRESS) =============== To run the test suite: ``` $ make tests ``` The tests depend on git and the HTTP::Daemon Perl module. Got may have to be installed system-wide before the tests will run successfully because paths to helper programs, such as got-read-pack, are hard-coded in user-facing binaries, such as got and tog. Operations such as clone and send which use the network will be trying to connect to 127.0.0.1 over ssh, as the same user who invoked 'make tests'. The command 'ssh 127.0.0.1' must succeed without any interactive prompting. The host key may need to be manually accepted once before running tests. An SSH key can be installed in ~/.ssh/authorized_keys for authentication. The OpenBSD version of Got also has tests for gotd and gotwebd. These tests cannot be run in -portable yet. There are environment variables which control some test parameters: GOT_TEST_PACK=1 will force tests to use pack files instead of loose objects. GOT_TEST_PACK=ref-delta will force use of pack files with ref-deltas rather than offset-deltas. GOT_TEST_ALGO=sha256 will run tests with sha256 repositories. GOT_TEST_ROOT can be set to a path where temporary test data gets stored. This defaults to /tmp. Dependencies ============ * ed NOTE: THIS ONLY WORKS AFTER `make install` DUE TO HOW PATHS TO LIBEXEC HELPERS ARE HARD-CODED INTO THE BINARIES. INSTALLATION ============ ``` $ ./autogen.sh $ ./configure && make $ sudo make install ``` INSTALLING AND PACKAGING GITWRAPPER =================================== The gotd server has an optional companion tool called gitwrapper. A gotd server can be used without gitwrapper in the following cases: 1) The Git client's user account has gotsh configured as its login shell. 2) The Git client's user account sees gotsh installed under the names git-receive-pack and git-upload-pack, and these appear in $PATH before the corresponding Git binaries if Git is also installed. Setting up the user's $PATH in this way can require the use of SetEnv in sshd_config. The above cases can be too restrictive. For example, users who have regular shell access to the system may expect to be able to serve Git repositories from their home directories while also accessing repositories served by gotd. Once gitwrapper has been installed correctly it provides an out-of-the box experience where both gotd and Git "just work". However, this will require coordination with the system's Git installation and/or distribution package because the names of two specific Git programs will be overlapping: git-upload-pack and git-receive-pack If the gitwrapper tool will be used then it must replace git-receive-pack and git-upload-pack in /usr/bin. This is usually achieved by replacing the regular Git binaries in /usr/bin with symlinks to gitwrapper: ``` -rwxr-xr-x 1 root root 1019928 Aug 24 00:16 /usr/bin/gitwrapper lrwxrwxrwx 1 root root 10 Aug 20 12:40 /usr/bin/git-receive-pack -> gitwrapper lrwxrwxrwx 1 root root 10 Aug 20 12:40 /usr/bin/git-upload-pack -> gitwrapper ``` The Git binaries remain available in Git's libexec directory, which is set when Git gets compiled. On Debian it defaults to /usr/lib/git-core. This same path must be given to Got's configure script at build time to allow gitwrapper to find Git's binaries: ``` ./configure --with-gitwrapper-git-libexec-path=/usr/lib/git-core ``` Once gitwrapper is found in /usr/bin under the names git-receive-pack and git-upload-pack, any Git repositories listed in /etc/gotd.conf will be automatically served by gotd, and any Git repositories not listed in /etc/gotd.conf will be automatically served by regular Git's git-upload-pack and git-receive-pack. The client's login shell or $PATH no longer matter, and a peaceful co-existence of gotd and Git is possible. We recommend that distribution packagers take appropriate steps to package gitwrapper as a required dependency of gotd. It is also possible to install gitwrapper without installing gotd. As long as /etc/gotd.conf does not exist or no repositories are listed in /etc/gotd.conf there will be no visible change in run-time behaviour for Git users since gitwrapper will simply run the standard Git tools. In the OpenBSD ports tree both the regular git package and the gotd package are depending on gitwrapper, and the git package no longer installs the git-receive-pack and git-upload-pack programs in /usr/local/bin. BRANCHES + SUBMITTING PATCHES ============================= `got-portable` has two key branches: * `main` which tracks got upstream untainted. * `portable` which provides the portable version of GoT based from code on `main` Patches for portable code fixes should be based from the `portable` branch and sent to the mailing list for review [2] or sent to me directly (see CONTACT). Portable-specific patches should have a shortlog in the form of: ``` portable: AREA: description ``` Where `AREA` relates to the change in question (for example, `regress`, `libexec`, etc). In some cases, this can be omitted if it's a generic change. This helps to delineate `-portable` changes from upstream `got`. The read-only Github repository also runs CI checks using Cirrus-CI on Linux and FreeBSD. SYNCING UPSTREAM CHANGES WITH PORTABLE ====================================== The `-portable` GoT repository uses the following workflow: ``` Github (gh) GoT (upstream) ^ ^ | | | | | | | | +--------> GoT-portable <------+ ``` Here, `got-portable` is a clone of the `-portable` repository, locally on disk. There are two remotes set up within that repository, via `git-remote`: * `upstream` -- which points to the official GoT repository; * `gh` -- which points to the mirrored `-portable` repository so that CI can be run for cross-platform/test purposes [3] * `origin` -- our cloned copy from `-portable` Within the `-portable` repository are two key branches (there may be other topic branches which represent on-going work): * `main` -- this is the branch that tracks (without modification) those changes from `upstream`. This branch is continually reset to `upstream/main` whenever changes occur. * `portable` -- this is the *default* branch of the `-portable` repository which contains portable-specific changes to make `GoT` compile across different OSes. When updating `-portable` from upstream changes, the following actions happen: 1. Changes from `upstream` are fetched. If there are no new changes, there's nothing else to do. 2. Changes from `gh` are fetch so that the result can be pushed out to `gh`. 3. The difference between the local copy of `main` and `origin/main` is used to represent the set of commits which have *NOT* yet been merged to `-portable`. 4. A topic-branch called `syncup` is created from the HEAD of the `portable` branch to hold the to-be-cherry-picked commits from step 3. 5. These commits are then cherry-picked to the `syncup` branch. 6. If there's any conflicts, they must be resolved. 7. Once done, a sanity build is done in-situ to check there's nothing amiss. 8. If that succeeds, the `syncup` branch is merged to `portable` and pushed to `gh` for verification against CI. 9. If that fails, fixes continue and pushed up to `gh` as required. 10. Once happy, both the `main` and `portable` branches can be merged to `origin`. These steps are encapsulated in a script within `-portable`. [Link](../maintscripts/sync-upstream.sh) RELEASING A NEW VERSION ======================= Release for `-portable` try and align as close to upstream GoT as much as possible, even on the same day where that can happen. That being said, sometimes a release of `-portable` might happen outside of that cadence, where a `-portable`-specific issue needs addressing, for example. Before creating a new release, check the version of GoT as found in `util/got-portable-ver.sh` -- as `GOT_PORTABLE_VER`: ``` GOT_PORTABLE_VER=0.75 ``` Here, the *to be released* version of `got-portable` will be `0.75`. Typically, this version is incremented directly after a release, such that there's no need to change this value. The only exception would be if there were an out-of-band release to `-portable`. In such cases, that would take the form: ``` 0.75.1 ``` Where the suffix of `1`, `2`, etc., can be used to denote any sub-releases from the `0.75` version. The variable `GOT_RELEASE` needs be changed to `yes` so that the GOT_PORTABLE_VER is asserted correctly. Once the version is verified, the following should be run from the `portable` branch -- and the repository should not have any outstanding modifications to the source: ``` make clean ; ./autogen && ./configure && make distcheck ``` If this succeeds, the tarball is in the CWD, as: `got-portable-VERSION.tar.gz` This can then be copied to the `got-www` repository and uploaded, along with changing a couple of HTML pages therein to represent the new released version. Additionally, the CHANGELOG file can be copied to the `got-www` and committed. Once all of that has been done, the repository should be tagged to indicate the release, hence: ``` git tag -a 0.75 ``` This can then be pushed out to `gh` and `origin`. After that point, the version of `GOT_PORTABLE_VER` in `util/got-portable-ver.sh` should be changed to the next version, and `GOT_RELEASE` should be setg back to `no`. TODO ==== * configure.ac should start defining AC_ENABLE arguments to allow for finer-grained control of where to search for includes/libraries, etc. * review the compat/ code. Some of those functions are probably picked up in libbsd, so we should drop such implementations from compat/ where there's overlap between libbsd and what's natively available.

Comments can be put anywhere in the file using a hash mark .Pq Sq # , and extend to the end of the current line. Arguments names not beginning with a letter, digit or underscore, as well as reserved words .Pq such as Ic listen , Ic server No or Ic user , must be quoted. Arguments containing whitespace should be surrounded by double quotes .Pq \&" . .Pp Macros can be defined that are later expanded in context. Macro names must start with a letter, digit, or underscore, and may contain any of those characters, but may not be reserved words. Macros are not expanded inside quotes. For example: .Bd -literal -offset indent lan_addr = "192.168.0.1" listen on $lan_addr port 9090 .Ed .Sh GLOBAL CONFIGURATION The available global configuration directives are as follows: .Bl -tag -width Ds .It Ic chroot Ar path Set the path to the .Xr chroot 2 environment of .Xr httpd 8 . If not specified, it defaults to .Pa /var/www , the home directory of the www user. Setting the .Ar path to .Pa / effectively disables chroot. .It Ic disable authentication Disable authentication, allowing any browser to view any repository not hidden via the .Ic respect_exportok directive. Authentication can also be configured on a per-server or per-repository basis. .It Ic enable authentication Oo Ic insecure Oc Enable authentication, requiring browsers to present a login token cookie before read-only repository access is granted. Authentication can also be configured on a per-server or per-repository basis. .Pp Browsers presenting a valid login token cookie will be mapped to the user account which obtained the login token over SSH from the .Cm weblogin command of .Xr gotsh 1 . .Pp Unauthenticated browsers will be mapped to the user account which runs .Xr httpd 8 . This user account can be set with the .Ic www user directive. Attempts to read repositories as this user will be denied unless authentication is disabled for the repository. .Pp Unless the .Ic insecure keyword is used, the login token cookie will be marked as .Dq Secure , which causes browsers to only send the cookie when connected to the web server over a TLS connection. .It Ic listen on Ar address Ic port Ar number Configure an address and port for incoming FastCGI connections. Valid .Ar address arguments are hostnames, IPv4 and IPv6 addresses. The .Ar port argument may be number or a service name defined in .Xr services 5 . May be specified multiple times to build up a list of listening sockets. .It Ic listen on socket Ar path Configure a .Ux Ns -domain socket for incoming FastCGI connections. May be specified multiple times to build up a list of listening sockets. .Pp While the specified .Ar path must be absolute, it should usually point inside the web server's chroot directory such that the web server can access the socket. .It Ic login socket Ar path Set the .Ar path to the .Ux Ns -domain socket for .Xr gotsh 1 .Ic weblogin commands. By default the path .Pa /var/run/gotweb-login.sock will be used. .It Ic prefork Ar number Spawn enough processes such that .Ar number requests can be handled in parallel. By default, .Xr gotwebd 8 will handle up to 3 requests in parallel. The maximum allowed is 32. .It Ic user Ar user Set the .Ar user which will run .Xr gotwebd 8 . If not specified, the user _gotwebd will be used. .It Ic www user Ar user Set the .Ar user which runs .Xr httpd 8 . Needed to ensure that the web server can access .Ux Ns -domain sockets created by .Xr gotwebd 8 . If not specified, the user www will be used. .El .Pp If no .Ic listen directive is used, .Xr gotwebd 8 will listen on the .Ux Ns -domain socket at .Pa /var/www/run/gotweb.sock . .Sh SERVER CONFIGURATION At least one server context must exist for .Xr gotwebd 8 to function. In case no server context is defined in the configuration file, a default server context will be used which uses default parameters for all applicable settings. .Pp A server context is declared with a unique .Ar name , followed by server-specific configuration directives inside curly braces: .Pp .Ic server Ar name Brq ... .Pp If more than one server is defined, each .Ar name should match the hostname which browsers use to reach the corresponding server. The first server defined is used if the requested hostname is not matched by any server block. .Pp The available server configuration directives are as follows: .Bl -tag -width Ds .It Ic custom_css Ar path Set the path to a custom Cascading Style Sheet (CSS) to be used. If this option is not specified then the default style sheet .Sq gotweb.css will be used. .Pp This path must be valid in the web server's URL space since browsers will attempt to fetch it. .It Ic logo Ar path Set the path to an image file containing a logo to be displayed. Defaults to .Sq got.png . .Pp This path must be valid in the web server's URL space since browsers will attempt to fetch it. .It Ic disable authentication Disable authentication for this server, allowing any browser to view any repository not hidden via the .Ic respect_exportok directive. Authentication can also configured on a per-repository basis. .Pp If not specified, the global configuration context determines whether authentication is disabled. .It Ic enable authentication Oo Ic insecure Oc Enable authentication, requiring browsers to present a login token cookie before read-only repository access is granted. Authentication can also configured on a per-repository basis. .Pp If not specified, the global configuration context determines whether authentication is enabled. .It Ic logo_url Ar url Set a hyperlink for the logo. Defaults to .Lk https://gameoftrees.org . .It Ic max_commits_display Ar number Set the maximum amount of commits and tags displayed per page. Defaults to 25. .It Ic max_repos_display Ar number Set the maximum amount of repositories displayed on the index screen. Defaults to 25. Set to zero to show all the repositories without pagination. .It Ic repos_path Ar path Set the path to the directory which contains Git repositories that the server should publish. This path is absolute. Repositories can be served even if they reside outside the web server's chroot directory. .Pp Defaults to .Pa /got/public inside the web server's chroot directory. The .Cm chroot directive must be used before the server declaration in order to take effect. .It Ic repository Ar name Brq ... Set options which apply to a particular repository served by this server. .Pp A repository context is declared with a unique .Ar name , followed by repository-specific configuration directives inside curly braces. .Pp The repository will be looked up within the server's .Ar repos_path , where the directory .Ar name can exist with or without a .Dq .git suffix. .Pp For each repository, access rules can be configured using the .Ic permit and .Ic deny configuration directives. Multiple access rules can be specified, and the last matching rule determines the action taken. .Pp If no access rules are set in a repository context, or if a repository exists in the server's .Ar repos_path without being mentioned in .Nm at all, then the access rules set in the server and global configuration contexts apply. If no rule matches then the repository will be inaccessible if authentication is enabled. .Pp The available repository configuration directives are as follows: .Bl -tag -width Ds .It Ic deny Ar identity Deny repository access to users with the username .Ar identity . Group names may be matched by prepending a colon .Pq Sq \&: to .Ar identity . Numeric IDs are also accepted. .It Ic permit Ar identity Permit repository access to users with the username .Ar identity . Group names may be matched by prepending a colon .Pq Sq \&: to .Ar identity . Numeric IDs are also accepted. .It Ic disable authentication Disable authentication, allowing any browser to view the repository. Any access rules configured with .Ic permit or .Ic deny directives for this repository will be ignored. .Pp If not specified, the server context or global context determines whether authentication is disabled. .It Ic enable authentication Oo Ic insecure Oc Enable authentication, requiring browsers to present a login token cookie before read-only repository access is granted. .Pp If not specified, the server context or global context determines whether authentication is enabled. .El .It Ic respect_exportok Ar on | off Set whether to display the repository only if it contains the magic .Pa git-daemon-export-ok file, regardless of whether authentication is enabled and has failed or succeeded. Disabled by default. .It Ic show_repo_age Ar on | off Toggle display of last repository modification date. Enabled by default. .It Ic show_repo_cloneurl Ar on | off Toggle display of clone URLs for a repository. This requires the creation of a .Pa cloneurl file inside the repository which contains one URL per line. Enabled by default. .It Ic show_repo_description Ar on | off Toggle display of the repository description. Enabled by default. The .Pa description file in the repository should be updated with an appropriate description. .It Ic show_repo_owner Ar on | off Set whether to display the repository owner. Enabled by default. This requires the creation of an .Pa owner file in the repository or adding an .Sq owner field under the [gotweb] or [gitweb] section in the .Pa config file inside the repository. For example: .Bd -literal -offset indent [gotweb] owner = "Your Name" .Ed .Pp The .Pa owner file has priority over the .Pa config if present. .It Ic site_link Ar string Set the displayed site link name for the index page. Defaults to .Sq Repos . .It Ic site_name Ar string Set the displayed site name title. Defaults to .Sq Gotweb . .It Ic site_owner Ar string Set the displayed site owner. Defaults to .Sq Got Owner . .It Ic show_site_owner Ar on | off Toggle display of the site owner. Enabled by default. .It Ic summary_commits_display Ar number The maximum number of commits to show in the summary page. Defaults to 10. .It Ic summary_tags_display Ar number The maximum number of tags to show in the summary page. Defaults to 3. .El .Sh FILES .Bl -tag -width Ds -compact .It Pa /etc/gotwebd.conf Default location of the .Nm configuration file. .It Pa /var/www/run/gotweb.sock Default location for the .Xr gotwebd 8 .Ux Ns -domain socket. .El .Sh EXAMPLES A sample configuration which allows public browsing: .Bd -literal -offset indent www user "www" # www username needs quotes since www is a keyword server "localhost" { site_name "my public repos" site_owner "Flan Hacker" site_link "Flan' Projects" disable authentication } .Ed .Pp Another example, this time listening on a local port instead of the implicit .Ux Ns -domain socket, and serving repositories located outside the web server's chroot: .Bd -literal -offset indent listen on 127.0.0.1 port 9000 listen on ::1 port 9000 server "localhost" { site_name "my public repos" repos_path "/var/git" disable authentication } .Ed .Pp The following example illustrates the use of directives related to authentication: .Bd -literal -offset indent # 3 scopes: global, per-server, per-repository disable authentication # override the default which is 'enable' # Allow user "admin" to read anything unless overridden with a # "deny" rule later. permit "admin" server "public.example.com" { # inherit global default, i.e. authentication is disabled repos_path "/var/www/got/public" } server "secure.example.com" { enable authentication # override global default permit flan_squee # grant access to flan_squee permit :developers # grant access to developers group repos_path "/var/git" repository "got" { # /var/git/got and /var/git/got.git # Grant access to users who have authenticated as # the anonymous user to gotsh(1), which anyone with # an SSH client sbould be able to do. # Dumb web crawlers will remain locked out. permit anonymous } repository "public" { # As an exception, allow any web browsers and # web crawlers to view this repository. disable authentication } repository "secret" { deny admin # not even the admin can read this } } .Ed .Sh SEE ALSO .Xr got 1 , .Xr httpd.conf 5 , .Xr services 5 , .Xr gotwebd 8 , .Xr httpd 8 got-portable-0.119/gotwebd/gotwebd.c0000664000175000017500000006577415066536113013071 /* * Copyright (c) 2016, 2019, 2020-2021 Tracey Emery * Copyright (c) 2015 Reyk Floeter * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above * copyright notice and this permission notice appear in all copies. * * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF * MERCHANTABILITY AND FITNESS.

The program has been designed to work out of the box with the .Xr httpd 8 web server. .Pp .Nm provides the following options: .Bl -tag -width tenletters .It Fl D Ar macro Ns = Ns Ar value Define .Ar macro to be set to .Ar value . Overrides the definition of .Ar macro in the configuration file. .It Fl d Do not daemonize. Send log output to stderr. .It Fl f Ar file Set the path to the configuration file. If not specified, the file .Pa /etc/gotwebd.conf will be used. .It Fl n Parse the configuration file, report errors if any, and exit. .It Fl v Verbose mode. Verbosity increases if this option is used multiple times. .El .Pp Enabling .Nm requires the following steps: .Bl -enum .It The .Xr httpd.conf 5 configuration file must be adjusted to run .Nm as a FastCGI helper program. The .Sx EXAMPLES section below contains an appropriate configuration file sample. .It httpd(8) must be enabled and started: .Bd -literal -offset indent # rcctl enable httpd # rcctl start httpd .Ed .It Optionally, the run-time behaviour of .Nm can be configured via the .Xr gotwebd.conf 5 configuration file. .It Git repositories must be created. These repositories may reside anywhere in the filesystem and must be readable, but should .Em not be writable, by the user .Nm runs as.

Assuming the default route interface is em0, this line in /etc/pf.conf should work: match out on em0 from "100.64.0.0/10" nat-to (em0) pf(4) must be configured to pass DNS requests from the guest IP range to a working DNS resolver: match in on tap inet proto udp from "100.64.0.0/10" to any \ port domain rdr-to 127.0.0.1 Replace 127.0.0.1 with your preferred resolver. The pf(4) ruleset must be reloaded: # pfctl -f /etc/pf.conf IP forwarding must be enabled for IPv4 traffic: # sysctl net.inet.ip.forwarding=1 The test suite defaults to the virtual machine name: gotsysd-test This name can be passed to vmctl(8) to control the VM. The tests require a base disk image which is used to avoid running a full VM installation for each run of the tests. The base image must be created manually by performing a scripted autoinstall(8) installation: # make vm The base disk image will be removed by 'make clean'. Once the installation has completed, wait until the guest has booted into the installed system. Once the installed system has booted successfully, the VM can be shut down from the host: # vmctl stop gotsysd-test The gotsysd test suite also tests gotwebd user authentication. These tests require the w3m browser to be installed: # pkg_add w3m Now the actual test suite can be run with: # make A test VM will be started automatically and stopped again once the tests have finished running. got-portable-0.119/regress/gotsysd/build-got.sh0000775000175000017500000000100315066535722015206 #!/bin/sh set -e cd ~/src/got # Because we copied this got src tree from the host the modified-timestamps # on already compiled files might be off.
