In that situation libdar may fail reading the archive (but succeeds in normal read mode) issuing an obscure message (message has also been fixed). - code simplification, removing field reading_verion from class crypto_sym as its parent class tronconneuse already have such information - removed extra newline displayed by dar at end of execution - fixed bug avoiding dar to properly read an entry (reporting CRC error) when specific sequence of character (start of escape sequence) fall at end of the read buffer of the escape layer. - speed optimization for datetime class - fixed bug that avoided dar reading archives in sequential read mode while reading from a pipe - fixed bug in non regression test routine provided beside dar/libdar - fixing display message showing not always in the correct context - fixing case inversion leading the cache layer not to be used when necessary and used when useless while reading an archive - improved heuristic in dar_manager to determine the date a file has been deleted. from 2.5.0 to 2.5.1 - fixed display bug in dar_manager met when using -o option and adding options for dar that does not exist for dar_manager (like -R option) - reactivating disabled (by mistake) optimization for some read-only dar manager database operations - fixing compilation issue with dar against gcc 4.9.2 - fixing syntax error in dar_manager message - fixed bug that forbade dar_manager to write down modified database when only database header was modified (-o, -b, -p switches). - adding dar_manager database format version information with -l option - fixed libdar inability to read dar_manager's database format version 4 - adapting code to build under cygwin environment, where thread_local seems broken - fixed output to stderr in place of stdout for Licensing information - fixed bug met when permission is denied while reading or writing slices - fixing bug that avoided creating an archive at the root of the filesystem from 2.4.x to 2.5.0 - added support for posix_fadvise() - added entrepot class hierarchy to support in the future other storage types than local filesystem for slices - API: added access to the entrepot through the API - modified class hash_fichier for it becomes entrepot independent - API: extended libdar API with an additional and more simple way to read an archive: archive::get_children_in_table() method, see doc/API_tutorial.html for details - added support for extX (see lsattr(1)) and HFS+ (birthtime date) Filesystem Specific Attributes (FSA). - dar is now able to skip backward when a file is found to be "dirty" at backup time. This avoids wasting space in archive but is only possible if the backward position is located in the current slice and no slice hashing nor strong encryption is used. Of course if the archive is written to a pipe or to stdout, skipping back to retry saving data at the same place is neither possible, --retry-on-change option stays possible in that cases at the cost of data duplication (wasted bytes amount, see --retry-on-change man page). - by default dar now performs up to 3 retries but do not allow for wasting bytes if file has changed at the time it was read for backup, this can be modied using --retry-on-change option. - With the same constraints as for a changing file, if a file is saved compressed but its compressed data uses more space than uncompressed, the file's data is resaved as uncompressed. However, if skipping backward is not possible, data is kept compressed. - if system provides it, dar uses "Linux capabilities" to check for the ability to set file ownership when dar is not run as root. This allows dar to restore ownership when allowed even when it is not run as superuser. - removing dar-help tool used to build dar -h messages. That tool became useless for a long time now. - added several more specific verbosity options: -vm, -vf and -vt - added support for microsecond timestamps (atime, mtime, ctime, birthtime) - Using lutime() to restore atime/mtimes of symlink on systems that support it. - API: removed backward compatible API for old libdar 4.4.x - API: simplified implementation of archive isolation thanks to isolation evolution features brought by release 2.4.0. Memory requirement is now devided by two compared to releases of previous branch (2.4.x). - dar has been updated to use this new API for archive isolation - added exclude-by-ea feature to avoid saving inodes that have a particular user defined EA set. - added comparison of an isolated catalogue with a filesystem, relying on embedded data CRC and inode metadata in absence of the saved data. - The new archive format (version 9) holds the ciphering algorithm used at creation time, only the passphrase is now required at reading time and -K option may be ignored which will lead dar to prompt for passphrase. - Adding support for public key encryption (GnuPG) supporting several encryption keys/recipients for a given archive - Adding support for public key signature when public key encryption is used - While listing archive contents, directories now show the size and average compression ratio of the data they contain - Archive summary (-l with -q options) now reports the global compression ratio - added the -vd switch to only display current directory under process for creation, diff, test, extraction and merging operations - added xz/lzma compression support - added -Tslicing listing option to show slice location of files inside an archive archive. - isolated catalogues now keep a record of the slicing layout of their archive of reference in order to provide -Tslicing feature when used on the isolated catalogue alone. - However if an archive has been resliced (using dar_xform) after its isolated catalogue has been generated, using -Tslicing option with the isolated catalogue would give wrong information. To overcome that, it is possible to specify what is the new slicing of the archive of reference by using the -s and -S options in conjunction with -Tslicing - added dar_split command to provide on-fly multi-volume archive support for tape media - experimental feature to have libdar using several threads (not activated by default due to poor performance gain) - dar now aborts when a given user target cannot be found in included file - added sha512 hashing algorithm beside already available md5 and sha1, the generated hash file can be used with 'sha512sum -c ' command - removed useless --jog option for memory management - removed previously deprecated -y/--bzip2 command, bzip2 compression remains available using -z option (-zbzip2 or --compression=bzip2) - replaced SHA1 by SHA224 to generate IV for encryption blocks, this slightly improves randomness of IV and stay available when libgcrypt is run in FIPS mode from 2.4.19 to 2.4.20 - fixed display bug in dar_manager met when using -o option and adding options for dar that does not exist for dar_manager (like -R option) - reactivating disabled (by mistake) optimization for some read-only dar manager database operations - fixing compilation issue with dar against gcc 4.9.2 - fixing syntax error in dar_manager message - fixing bug that avoided creating an archive at the root of the filesystem from 2.4.18 to 2.4.19 - fixed missing quote in dar_par.dcf which is called by the par2 directive - fixed bug in dar_manager's -u option, not displaying most recent files of an archive when they have been marked as removed in a more recent archive of the same dar_manager database. - fixed bug met while restoring in sequential read mode a file having several copies (was modified at the time it was saved and retry-on-change was set). from 2.4.17 to 2.4.18 - Initial Vector used for strong encryption was set with pseudo-random data generated using SHA1 message digest and blowfish cipher, which are not available when ligcrypt is running in FIPS mode. Since 2.4.18 we now use SHA256 and AES256 for IV assignment in order to have libdar compatible with FIPS mode. For data encryption nothing changes: the cipher specified (-K, -J, -$ options on CLI) are used as before. - fixing bug met when performing archive isolation in sequential-read mode, If an archive corruption or truncated archive leads an inode to not have its CRC readable, dar aborts and issues a BUG report. - updating list of project relying on dar/libdar from 2.4.16 to 2.4.17 - fixing issue when case insensitive comparison was requested and invalid wide char for the current local was met in a filename. In such situation the corresponding file was never saved before (considering a filesystem error for that file), while now the ASCII case insensitivity is used as fallback. from 2.4.15 to 2.4.16 - fixing archive listing displayed information for catalogue size when archive is read in --sequential-read mode - fixing bug that avoided dar releases 2.4.x up to 2.4.15 to read encrypted archive generated by dar release 2.3.x and below - adding informational note at the end of ./configure script execution when --enable-mode has not been used. - adding support for case sensitivity in filename comparison (-an option) for other character sets than POSIX/C locale like Cyrillic for example. - fixing bashisms in doc/samples scripts from 2.4.14 to 2.4.15 - fixing bug met when reading an encrypted archive in sequential mode - fixing bug met when reading an encrypted archive in sequential mode from an anonymous pipe - changed option '-;' to -9 as '-;' does not work on all systems with getopt (only long option equivalent --min-digits worked) for dar, dar_cp, dar_manager, dar_xform and dar_slave commands. - fixing bug met when restoring deleted files in sequential read mode and some directory where they should be "restored" are not readable or could not be restored earlier - adding extra buffer to handle sequential read of encrypted archive when the last crypto block contains some but not all clear data after encrypted one (the archive trailer). - fixing compilation issue using clang - fixing bug that prevents using -~ option with on-fly catalogue isolation in order to execute an user command once on-fly isolation has completed - added some autoconf magic to determine the correct (BSD/GNU) flag to use with sed in order to activate regular expression parsing - new implementation of mask_list class which is compatible with libc++ - fixed bug met on FreeBSD with dar_xform where the system provides a standard input file descriptor in read-write instead of read-only mode. from 2.4.13 to 2.4.14 - limiting memory consumption of the cache layer to stay below 10 MiB, under certain circumstances (very large archive), it could grow up to an insane value like 50% or the available RAM. reducing to 10 MiB does not impact performance in a noticeable manner while it avoids system to swap out due to the libdar cache layer becoming huge. - added --with-pkgconfigdir to define an alternative path for libdar pkgconfig file (to ease portability to FreeBSD) - modified some Makefile.am for better FreeBSD support - fixed display bug in XML listing output concerning hard linked inodes - fixing typo in man page - fixing bug met while isolating a catalogue in --sequential-read mode. Using such isolated catalogue lead dar report an error about inaccessible EA. - displaying compression rate for sparse files even when they are uncompressed, sparse file detection also leads to compress files - fixing bug that lead libdar to fail comparing an inode having EA when comparison is done in --sequential-read mode - fixing display bug in in ligcrypt check of configure script for minimum required version - fixing 'make clean' to remove some forgotten files generated by 'make' from 2.4.12 to 2.4.13 - adding initialization value for two variables to avoid inappropriate warning when compiling with -Wall option - reducing UNIX_PATH_MAX by the system when not defined from 108 to 104 bytes to accommodate BSD systems - fixing assignment operator of class criterium that was not returning any value as it should - removing useless boolean expression that always succeeds in logical AND expression - adding support for back-slash of quoting characters in DCF files - fixed compilation issues with clang / FreeBSD, Thanks to Neil Darlow's server ;-) - fixed compilation warning due to deprecated symbols in libgcrypt header files - replaced gnu make specific rules by legacy ones to avoid automake warning about them - removed old unused stuff from misc sub-directory - adding warning at compilation time if libgcrypt used is older than 1.6.0 - adding warning at execution time if hash computation is requested with slices greater than 256 Gio and ligbcrypt dynamically or statically linked is older than 1.6.0 - adding alternative methods in list_entry API class to return dates as number of seconds - fixed bug in hour-shift (-H option) when comparing dates from an old extracted catalogue (archive format 7 or older). - fixed documentation bug about the meaning of the compression ratio - fixed a display bug about the "compression flag" wrongly displayed for uncompressed files - fixed unhandled exception when giving non number argument to -1 option from 2.4.11 to 2.4.12 - for correctness fixed delete vs delete[] on vector of char (not incidence reported) - fixed out of range access in routine used to read very old archive format - fixed error in logical expression leading a sanity test to be useless - removed duplicated variable assignment - updated FAQ - fixed typo and spelling errors - fixed bug (reported by Torsten Bronger) in the escape layer leading libdar to wrongly reporting a file as corrupted at reading time - fixed bug in the sparse file detection mechanism that lead the minimum size hole detection to become a multiple of the default value or specified one. This implied a less efficient reduction of sparse files because smaller holes in files were ignored - fixed and updated man page about --go-into option - updated full-from-diff target in /etc/darrc default file - added a debug option in hash_file class (option only used from testing tools) to troubleshoot sha1/md5 hash problem on slices larger than (2**38)+63 bytes, bug reported by Mike Lenzen and understood by Yuriy Kaminskiy at libgcrypt. Note: This bug is still open due to an integer overflow in libgcrypt. - backported from current development code an additional and more simple way to read an archive using the libdar API. This API extension is not used by dar command-line tools for now. - Fixing installation of libdar header files on Darwin, where "DARwin" macros were not filtered out from the generated libdar header files. - Fixing self reported bug 'generic_file.cpp line 309' met while comparing an archive with a filesystem - Update code in order to compile with gcc-4.8.2 in g++11 mode (partial implementation and adaptation of Fabian Stanke's patch) - Fixing bug met while performing a verbose archive listing in sequential read mode - Added Ryan Schmidt's Patch to properly display status at end of ./configure script under BSD systems (in particular Mac OS X) - Updating configure.ac script to fix warning reported by autoconf when generating the ./configure script - Addressed portability problem with BSD systems that do not provide a -d option to the 'cp' command, preventing proper installation of the Doxygen documentation. Fix based on patch provided by Jan Gosmann. from 2.4.10 to 2.4.11 - Modified behavior of 'dar -h' and 'dar -V', both now return 0 as exist status instead of 1 (which means syntax error). - Fixed bug: -Q is now available with -V under the collapsed form -QV or -VQ - fixed typo in documentation - fixed memory leakage met when dar fails a merging operation because the resulting archive is specified in an directory that does not exist. - fixed bug met when isolating a differential backup in sequential read mode - fixed bug about slice file permission not taking care about umask variable when the --hash feature is used. - fixed performance issue when reading an archive over a pair of piles using dar_slave (possibly over ssh) when the archive makes use of escape marks and when no encryption is used - added target "full-from-diff" in /etc/darrc default file - fixed bug avoiding reading an truncated archive in direct access mode with the help of an external catalogue. - new and better implementation of archive extraction in sequential read mode - fixing bug (segfault) met when hitting CTRL-C while reading an archive in sequential mode - fixing libdar.pc for pkg-config for the cflags given to external applications - fixed memory allocation/desallocation mismatches (delete vs delete [] ) concerning four vector of chars. - fixed error in logical expression leading a sanity test to be useless from 2.4.9 to to 2.4.10 - fixing libdar about dar_manager database corruption that occurred when deleting the first archive of a base containing a plain file only existing in that first archive. - Added code to cleanup databases instead of aborting and reporting that previously described type of database corruption. - Added feature when comparing archive with filesystem in order to report the offset of the first difference found in a file. This was necessary to help solving the following bug: - fixed bug in sparse file detection mechanism that could lead in some very particular (and rare) situations to the loss of one byte from file being saved. In that case testing the archive reported a CRC error for that file. So if you keep testing achives in your backup process and have not detect any problem, you can then keep relying on your old backups. This bug also expressed when merging archives: dar aborted and reported that a merged file had a different CRC than the one stored in the archive of reference. from 2.4.8 to 2.4.9 - fixed bug: during differential backup dar saved unchanged hard linked inode when a hard link on that inode was out of the -R root directory. This also has the effect to always save files with long names on NTFS filesystems (!) - Adapted patch provided by Kevin Wormington (new messages displayed) - Fixed syntax error in configure script about execinfo detection - Removed unused AM_ICONV macro from configure script - fixed bug met under Cygwin when auxiliary test command failed to link when libgcrypt was not available. - updated mini-howto by Grzegorz Adam Hankiewicz - updating French message translations - restricted security warning for plain files and hard linked plain files - fixed display bug in dar_cp when manipulating files larger than 2 GB - fixed SEGFAULT met when adding to a dar_manager database an archive which base name is an empty string - improved error message, reporting the -B included file in which a syntax error has been met - modified dar_manager database to consider both ctime and mtime as timestamp value for data of saved files. This suppresses the warning about badly ordered archives in database when at some files have been restores from a old backup. from 2.4.7 to 2.4.8 - documentation fixes and updates - improved database listing efficiency - reduced memory usage of the caching layer in libdar - fixed self reported bug caused by memory allocation failure - fixed a SIGSEGV caused by double free in dar_xform when syntax error is met on command-line - dar_xform was not able to properly transform archive generated by dar older than release 2.4.0 - fixed bug that lead dar be unable to remove a directory at restoration time - replaced old remaining "bcopy" occurrence by a call to memcpy - fixed compilation warning under ArchLinux - fixed crash met while creating a backup with on-fly isolation - fixed libdar behavior when reading a strongly corrupted encrypted archive from 2.4.6 to 2.4.7 - fixing memory allocation bug in crc class, that lead glibc aborting dar - reviewed code and replaced some remaining occurences of bzero/bcopy by their recommended replacement version - fixed compilation problem under Solaris - fixed bug that could lead a file to be wrongly reported as different from the one on filesystem, when that file has been changed while it was saved, then saved a second time but has its size modified since the first time it was saved. from 2.4.5 to 2.4.6 - fixed bug met while interrupting compressed archive creation, the resulting archive was only readable in --sequential-read mode - fixed bug met while reading an interrupted archive in sequential reading mode. It lead dar to not release some objects from memory at the end of the operation, which displayed an ugly error message from libdar selfcheck routine. - fixed message reporting unknown system group when converting gid to name (was reporting unknow "user" instead of unknown "group") - removing the $Id:$ macro from file as we moved from CVS to GIT - updating package to distribute Patrick Nagel's scripts and documentation - updated URL pointing to Patrick Nagel's web site - updating documentation describing how to get source code from GIT (no more from CVS) - fixed typo in configure.ac - added info on how to build a brand-new dar tarball from source in GIT - modifies the end of messages shown by -h option to point to man page for more _options_ rather than _details_ - replaced − in the HTML generated documentation by a standard ASCII dash - fixed alignement bug in CRC calculation that lead libdar based application to crash on sparc-based systems. from 2.4.4 to 2.4.5 - updated sample scripts to be compatible with dar's --min-digit option - added missing included file to be able to compile with gcc-4.7.0 - removing an unused variable in filtre.cpp - fixed a display bug when comparing archive with filesystem, leading to a segmentation fault (%S in place of %i in mask) - fixed bug leading dar to not restore some directories from differential backups when they are absent in the filesystem - fixed bug that show a "uncaught exception" message at the end of archive listing for dar shared binaries only, compiled in infinint mode, under ArchLinux - updated the configure script to link with libexecinfo when available - added possibility to disable the use of execinfo in libdar thanks to the new --disable-execinfo option for the ./configure script - added Andreas Wolff patch to fix bug under Cygwin (segfault on program termination). from 2.4.3 to 2.4.4 - fixed man pages in the NAME section: added whatis entry - fixed segfault: in the internal error reporting code (delete[] in place of free()) - fixed bug: dar_manager was not able to read properly the latest generated databases version when having Extended Attributes recorded for some files - avoided reporting unreleased memory block when compilation optimization have been used (dar, dar_manager, dar_cp, dar_slave, dar_xform do all reported unreleased memory when gcc optimization was used in "infinint" mode) from 2.4.2 to 2.4.3 - fixed absurd compilation warning about possibly uninitialized variable - added -ai switch to dar_manager to disable warning about improper file order in database. - fixed bug met while changing order of archives in a dar_manager database - avoiding concurrent use of -p and -Q options, error message shown in that situation. - modified slice overwriting detection code to use a single atomic system call to create a new slice - replaced delete by delete[] for conversion routine of user/group to uid/gid - added the possibility to disable speed optimization for large directories - added memory troubleshooting option --enable-debug-memory - simplified class CRC implementation - fixed failed memory release upon exception thrown in class deci - modified tlv, tlv_list classes and ea_filesystem routines to not require any corresponding temporary objects in libdar (saves a few new/delete calls) - fixed silent bug in tlv class: due to the absence of copy constructor and destructor, some memory was not released and referred after the corresponding object's destruction - modified generic_file class to avoid temporary crc objects - fixed bug in header class that lead unreleased field (this class lacked a destructor), memory impact was however little: 10 bytes per slice - fixing bug in class tlv: unreleased memory - added protection code in class deci to properly release memory against exception thrown from called routines when user interrupts the operation. - replace previous internal stack report code by backtrace()/backtrace_symbols() - complete change of the implementation of the 'special-alloc' feature: the old code eat too much memory not to be adapted to new features added in release 2.4.0. This new implementation also bring some speed improvement from 2.4.1 to 2.4.2 - fixing bug met when reading an archive in sequential-read mode - fixing bug while filtering in sequential-read mode - fixing backward compatibility in dar_manager with old archives (wrong dates for deleted files). - fixing compilation problem on certain systems (missing #include statement) - fixing documentation syntax and spelling from 2.4.0 to 2.4.1 - adding information about "Cache Directory Tagging Standard" in doc/Feature.html - fixing typo in doc/presentation.html - fixing incomplete information in doc/usage_notes.html - rewriting sample scripts from tcsh to bash in doc/usage_notes.html - updating Swedish translation with the last version from Peter Landgren which has been forgotten for 2.4.0, sorry. - fixing installation problem, where src/libdar/nls_swap.hpp was not installed - fixing version returned by libdar_4_4::get_version to let kdar (or other external program relying on the backward compatible API) working as expected - fixed bug in the code determining whether a directory is a subdirectory of another. This bug could lead dar to restore more files that just the one that were specified with -g option. - added -k option to dar_manager for backward compatible behavior of dar_manager - fixed bug in dar_manager, was recording the wrong date of EA removal (when an inode has dropped all its EA since the archive of reference was done). - adapted dar_par_test.duc sample script to dar-2.4.x new behavior - adapted libdar to MacOS X to restore mtime date after EA, as on this system, modifying some system specific EA implies updating the mtime. But dar cannot yet store and restore the "creation date", it needs specific MacOS X code, as this value is not available through Posix EA. - fixed backward compatibility bug where dar 2.4.0 was not able to read archive containing only a catalogue (differential backup when no change occurred, snapshot backup, extracted catalogue) generated by dar 2.3.x or older. - fixed self reported internal error met when dar is merging archives generated by dar 2.3.x versions. from 2.3.x to 2.4.0 - hard links support for pipes, soft links, char and block devices has been added (so far, only hard links on plain files were supported) - added rich overwriting feature for merging archives (-/ option) - changed default behavior of dar: it no more tries to preserve the atime of read files, which had as side effect to modify the ctime. See man page for -aa and -ac options for details - simplified the use of the "sed" command in Makefiles.am files - integrated Wiebe Cazemier's patch for man page - -E option has been extended to work also when generating a single sliced archive (no need to have -s option to be able to use -E option). - slice header has been extended to store additional information (slice layout is now redundant in each each slice and may be used as backup from a slice to another in case of corruption). - dar does no more need to read the first then the last slice of an archive to get its contents, it now instead only needs the last slice. - an isolated catalogue can now be used as backup of the original archive's internal catalogue (-A option in conjunction with -x option for example) - added directory look-up optimization (adaptation of Erik Wasser's patch) - added -e option support (aka dry-run) to archive testing - added the possibility to set permission and ownership of generated slices - re-designed the libdar API to have all optional parameters carried by class object in a single argument, the aim to not break backward compatibility of the API upon each new feature addition. The libdar_4_4 namespace can be used for backward compatibility with older applications (see API documentation) - added retry on change feature (-_ option). - changed storage for UID and GID from U_16 to infinint to support arbitrarily larger UID and GID - added lzo compression support - dar_manager now uses an anonymous pipe to send configuration to dar, this solves the problem due to command-line limitation. - dar now stores a "removal date" when a file disappeared since the archive of reference was done (so far only the information that a file was removed was stored). This is needed for dar_manager (see next new feature) - dar_manager can now better restore the status of a set of files exactly as it was at any given time from a set of full and differential backups. In particular, it does no more restore files that were removed at the requested date. - added check in dar_manager to detect conditions where a file has a modification date that has been set to the past. Two objectives are at the root of this feature: proper restoration of files and detection of possible rootkit - added mode for restoration that avoid restoring directory tree which do not contain any saved files (in particular when restoring a differential backup) see man page for -D option for more details. - reviewed implementation of code managing Extended Attributes (much faster now) - added batch feature (-@ option) to dar_manager - added Furtive Read Mode support (O_NOATIME + fdopendir): when the system supports it, while reading data, dar does not modify any date (ctime or atime) - added the possibility to have sequential reading of archives (ala tar) see option --sequential-read - added the possibility to read from a pipe (single pipe, without dar_slave) (use '-' as filename in conjunction with --sequential-read) - added -P -g -[ and -] options to archive listing (-l option) - added sparse file detection mechanism (can save and restore sparse files) - added dirty flag in archive for file that changed while being saved. By default a warning is issued when the user is about to restore a dirty file, this can be changed thanks to the --dirty-behavior option - -R option can receive an arbitrary string (still is excepted an empty string) In particular dar will no more complain if the given path contains // or \\ however it must in a way or another point to something that exists! - added a short listing feature (listing only the summary), (using both -l and -q options) - extended conditional statements in included files (DCF) with user defined targets (see user target paragraph at the end of dar man page) User targets let the user add a set of options using a single keyword on command-line. - a sample /etc/darrc is now proposed with some user targets for common operation like compression without compressing already compressed files. - dar now releases filedescriptors of archive of reference(s) before proceeding to the operation (differential backup, archive isolation, etc.) - user can add a comment in archive header some macro are provided for common options (see --user-comment in man page). This comment can be seen when listing an archive in verbose mode (-l -v) or when displaying the archive's summary (-l -v -q). - added a "security warning" feature if ctime has changed in filesystem while inode has not changed at all (-asecu disables this feature). This is to target possible rootkit files. Note that this may toggle false positive, if for example you change EA of a file. - added feature: DAR_DUC_PATH environment variable, which let dar look for a DUC file (see -E and -F options) in the given path. - added feature: DAR_DCF_PATH environment variable, same as previously but for DCF files (see -B option). - added two targets for conditional syntax: "reference:" and "auxiliary:" - weak blowfish implementation has been removed (no backward compatibility as it suffered of a weak Initial Vector (IV) initialization), but the normal blowfish encryption stays in place. - Due to openssh licensing, replaced openssh by libgcrypt dependancy (which stays optional). - added new cyphers aes256, twofish256, serpent256 and camellia256 - added the hash feature (--hash option), supporting md5 and sha1 algorithms. The hash is calculated on the fly for each slice, before its data is even written to disk. This let one to check for media corruption even before a multi-sliced archive is finished. However this does not prevent an archive to be corrupted due to a software bug (in dar, libdar or in a external library), so it is always recommended to test the archive using dar's -t option. - -G option (on-fly isolation) has been replaced by -@ when creating an archive, to reduce the number of letter used for options. This also let available the usual switches associated to -@ option to define an encryption algorithm and passphrase for the on-fly isolated catalogue. - slices number may be padded with zeros (--min-digits option) Note that if using this option when creating an archive, this same option is required for any operation on this archive - added -konly feature to only remove files recorded as suppressed at differential backup restoration time. - dar and libdar now store keys in secure memory (with the exception that a DCF is parsed in unlocked memory, having a key in a DCF file is not as secure as having dar asking for password at execution time using the "-K :" syntax) - added hook for backup: a user command or script can be run before saving and after backing up files that match a given mask all along the backup process (see -<, -> and -= options). - added feature: -alist-ea let the user see the Extended Attributes of files while listing an archive contents. - dar_manager can receive negative numbers to point to archive counting by the end of the database. - dar and libdar stay released under GPL 2.1 (not under GPL 3, and not lesser GPL, neither) - setting the "little/big endian" to usual meaning (it was inverted in the code) this does not change the dar's behavior nor its compatibility with different systems or older libdar versions. - added -ai option to avoid warning for unknown inode types - added support for Solaris's Door files - added feature: decremental backup from 2.3.11 to 2.3.12 - avoiding concurrent use of -p and -Q options, error message shown in that situation. version 2.3.10 to 2.3.11 - fixed bug in the detection code of an existing archive of the same name when creating a new archive (improperly considered some files sharing a part of the archive basename as old slices of an archive of the same base name). - fixed a display bug. When using -v to see which arguments get passed to dar by mean of configuration file (DCF file, ~/.darrc or /etc/darrc) the last argument found in file was not displayed. - fixed two bugs (one in decompression routine, the other in decryption routine) that lead dar to segfault or run into an endless loop when reading a very corrupted archive. - added -H option with -d option - fixed bug leading Dar to report some files to be removed at restoration time to be of different type than the expected one when the reference used for that archive (difference backup) was an extracted catalogue. - fixed bug in dar's command_line parsing leading dar to free twice the same block of memory when an argument containing a double slash was given to -G [SF 3162716]. - probable fix (problem difficult to reproduce) for double memory release in the storage class [SF 3163389] version 2.3.9 to 2.3.10 - added patch by Jan-Pascal van Best to have -[ and -] options working with archive merging - fixed bug in displaying dates [SF 2922417] - enhanced pseudo random number generation used in dar - added an error message when an include/exclude file listing does not contains an invalid path (instead of a self reported bug message). - modified message displayed when some slice of an old archive having the same name are present in the destination directory (backup, isolation, merging, dar_xform) from 2.3.8 to 2.3.9 - fixed bashism in doc/examples/pause_every_n_slice.duc sample script [SF 2020090] - added Jason Lewis's script "dar_backups.sh" which is an enhanced version of n the script done by Roi Rodriguez Mendez & Mauro Silvosa Rivera. - added message asking software upgrade to handle case when new archive format (used by dar >= 2.4.0) is provided to dar - very little optimization of the reading process of EA - updated FAQ - replaced "Catalogue" by "Archive Contents" in output message (-l -v). - added Sergey Feo's patch to dar_par.dcf - added check against stddef.h header file presence in configure script - fixed spelling - added Charles's Script in doc/sample - added -q option to dar - added licensing exception to allow distribution of dar beside OpenSSL library - Bug fix: during archive diff (only), dar restore atime of file in the backup instead of file in the system before opening it for reading. - tested dar with valgrind from 2.3.7 to 2.3.8 - fixed bug in libdar met when user supply an empty file as a list of file to include or exclude ( -[ and -] options ) - fixed bug concerning elastic buffers used beside strong encryption. No security issue here, just in some almost rare situations the generated archive was not readable (testing your archive prevents you loosing data in this situation) - added some speed optimizations - avoided warning to appear without -v option set, when an error is met while fetching value of nodump flag (flag not supported on filesystem for example). from 2.3.6 to 2.3.7 - fixed bug in dar_manager about the localization of the archive in which to find the latest EA - fixed bug in configure script to properly report full blowfish encryption support - fixed a bug in the statistics calculus of dar_manager for most recent files per archive - removed inappropriate internal error check - added --disable-libdl-linking option - fixed mistake in API tutorial - updated Swedish translation by Peter Landgren - fixed bug in the file filtering based on listing file ( -[ option ) - fixed typo and spelling errors in documentation - updated code for clean compilation with gcc-4.2.3 - updated code for clean compilation with gcc-4.3 20080208 (experimental gcc) from 2.3.5 to 2.3.6 - fixed Makefile.am in src/dar_suite (removed "/" after $(DESTDIR)) - fixed bug in regex mask building when not using ordered masks - fixing bug that led dar_manager to report no error while some files failed to be restored due to command-line for dar being too large. - fixed bug met when user aborts operation while dar is finalizing archive creation [SF #1800507] - fixed problem with execvp when dar_manager launches dar from 2.3.4 to 2.3.5 - changed displayed message when adding a hard link to an archive while performing a differential backup - added back the possibility to use old blowfish implementation (bfw cipher) - integrated optimization patch from Sonni Norlov - updated Swedish translation by Peter Landgren - updated French translation - fixed broken Native Language Support in 2.3.x (where x<5) from 2.3.3 to 2.3.4 - fixed behavior when differential backup is interrupted (no more store file that would have been read if no interruption had been done as "deleted" since the archive of reference) [SF #1669091]. - added official method to access catalogue's statistics through the API (for kdar next version). - Fixed syntax error in dar_par_create.duc and dar_par_test.duc files (Parchive integration with dar). - minor spelling fix in error message (compressor.cpp) - added Wiebe Cazemier's two patches for dar man page - integrated patch from Dwayne C. Litzenberger to fix weakness in dar's implementation of the blowfish encryption. - improved the returned message when an invalid path is given as argument - updated doc/sample/sample1.txt script file from 2.3.2 to 2.3.3 - avoid using getpwuid() and getgrgid() for static linking. - fixed typo in dar's man page - update FAQ - fixed bug: uncaught exception thrown when CTRC-C was hit while dar waits an answer from the user [SF #1612205] - fixed bug: unusable archive generated when CTRC-C was hit and blowfish encryption used [SF #1632273] - added a check to verify that the libdar used is compatible with the current dar suite programs [SF #1587643] - fixed bug: added workaround for the right arithmetic shift operator (the binary produced by gcc-3.4.2 produces computes "v>>s" equal to "v" when when v is a integer field composed of s exactly bits. It should rather compute it to zero...). this problem leads 32 bits generated archive incompatible with 64 bits generated archive only when blowfish is used. - fixed bug met when the inode space is exhausted, thanks to "Jo - Ex-Bart" for this new feedback. [SF #1632738] - replaced &, <, >, ' and " in XML listing by &...; corresponding sequence. [SF #1597403] - dar_manager can receive arguments after stick to -o options (it is an error in regard to documentation, but no warning was issued in that case, leading to confusion for some users) [SF #1598138] - updated Veysel Ozer's automatic_backup script - fixed hard link detection problem [SF #1667400] - verbose output did not displayed hard links information - merged patch on dar_cp by Andrea Palazzi to have it to return EXIT_DATA_ERROR when some data have been reported [SF #1622913] from 2.3.2 to 2.3.3 - avoid using getpwuid() and getgrgid() for static linking. - fixed typo in dar's man page - update FAQ from 2.3.1 to 2.3.2 - fixed bug in Native Language Support when --enable-locale-dir was not set (Thomas Jacob's patch) - updated Swedish translation by Peter Landgren - --verbose=skipped was not available (only the short -vs form was available) - reviewed regex with ordered mask for the feature to better fits user's need (Dave Vasilevsky's feedback) - fixed bug where compression algorithm was changed to maximum (fixed with Richard Fish's adequate patch) - fixed tutorial with command line evolution (dar's -g option in particular) - latest version of Grzegorz Adam Hankiewicz's mini-howto - fixed bug concerning restoration of only more recent files from 2.3.0 to 2.3.1 - set back Nick Alcock's patch which has been dropped from 2.2.x to 2.3.x (patch name is "Do not moan about every single file on a non-ext2 filesystem") - fixed compilation problem when thread-safe code is disabled - integrated Wiebe Cazemier's patch for dar's man page - fixed bug in listing: -as option also listed files that had EA even when these were not saved in the archive - file permission of installed sample scripts lacked the executable bit - fixed a bug that appeared when a file is removed while at the time it is saved by dar - avoid having an unnecessary warning appearing when restoring a file in a directory that has default EA set - Cygwin has changed and does not support anymore the path in the form "c:/some/where", you have to use "/cygdrive/c/some/where" instead. Documentation has been updated in consequence. from 2.2.x to 2.3.0 - added user_interaction::pause2() method - added the snapshot feature - added the Cache Directory Tagging detection feature - adapted Wesley's patch for a pkgconfig for libdar - added -[ and -] options (file selection from file listing) Important consequence for libdar user programs: the fs_root argument is now expanded to full absolute path inside libdar, thus the mask you will give for path inclusion/exclusion (the "subtree" argument)will be used against full absolute path of files under consideration for the operation. Assuming you have fs_root=tmp/A and the current directory is /tmp, your mask will be used against strings like /var/tmp/A/some/file. (instead of tmp/A/some/file as in the previous API version). Things are equal if the fs_root is given an absolute path. - changed archive format to "05". Due to complete review of EA management. - upon some signal reception, dar aborts the backup nicely, producing a completely formatted archive will all the file saved so far. This archive can be take as reference for a further backup to continue the operation at a later time. - dar_manager aborts properly upon certain signal reception (do not let the database partially updated). - dar_slave and dar_xform now recognize when a slicename is given in place of a basename - reviewed thread_cancellation (API change) for it be possible to cancel several thread at the same time - prevent some dead-lock situation that can occur when a signal is received inside a critical section - dar_cp, dar_xform and dar_slave also abort nicely upon signal reception - dar_manager can now restore files based on a given date (not always the most recent version) - dar_manager now has an interactive mode (-i option) - change in API, the warning() method need not be overwritten, but the new protected method inherited_warning() must be inherited in its place (same function, same prototype as the original warning() method). - dar_manager features are now part of libdar. API has been completed with these new features - added the "last_slice" context (%c with -E option) when creating an archive - dar now check a file has not been modified while it was reading it, if so it reports a warning and returns a specific exit code - remove included gettext from the package (it is more a source of conflict with external gettext and if somebody needs internationalization better is to install libintl/gettext on its own). - added George Foot feedback about the good backup practice sort guide. - added -e option to dar_manager - added the progressive_report feature in the API - dar can now pause every N slice where N >= 1 - integrated Dave Vasilevsky's patch to support Extended Attributes and file forks under MacOS X - added method in API for external program be able to list dar_manager databases, their file contents and the statistics - added the merge/sub-archive feature - remove [list of path] from command line (-g option is now mandatory) - added regex expression in filters (-ar/-ag options) - added -ak option - added the --comparison-field option (extension of the --ignore-owner option aka -O option) - added the -af option (backup files more recent than a given date, others are keept as already saved) - dar now take care that an escape character can be sent when pressing the arrow keys and avoid considering them in this situation - dar will no refuse to abort if user presses escape when dar asks the user to be ready to write to a new slice - adapted Wesley Legette's patch for an xml archive listing - added 'InRef' status for EA (same meaning as the one for file's data) from 2.2.6 to 2.2.7 - updated Swedish translation by Peter Landgren - fixed bug #37 - added old function (modified in 2.2.6) for backward compatibility - added German translation by Markus Kamp from 2.2.5 to 2.2.6 - fixed bug #36 - avoid removing slices when creating archive in dry-run mode (-e option) - fixed display problem in dar_cp that lead uncaught exception just before exiting from 2.2.4 to 2.2.5 - limited size of internal buffers allocated on the stack to not be greater than SSIZE_MAX when this macro is defined. This comes from feedback from "Steffe" at sourceforge after he ported dar to HPnonStop. - integrated Andrey Yasniy's patch: fixed differential backup problem with ru_RU.koi8-r locale. - integrated Nick Alcock's patch: no warning shown when not on EXT2 filesystem and nodump feature has been activated. - avoid having arrow key be interpreted as escape key (while they remains an escape key + one char, as received from the tty). - added part of Kyler Klein's patch for OSX (Tiger) (only concerns included gettext) from 2.2.3 to 2.2.4 - fixed #35 - added in doc/samples the backup Script of Rodriguez Mendez & Mauro Silvosa Rivera - updated Swedish translation by Peter Landgren from 2.2.2 to 2.2.3 - error in TUTORIAL (-P only receives relative paths) - updated FAQ with memory requirement questions/problem - added Bob Barry's script for determining memory requirement - added documentation about NLS in doc/NOTES - fixed bug concerning the << operator of infinint class.

-Q option now forces the non terminal mode even when dar is run from a terminal (tty) this makes dar possible to run in background without having the shell stopping it upon text output. - removed unused control code for dar's command line syntax - spelling fix of the tutorial by Ralph Slooten - added the pertinent part of the memory leak patch from Wesley Leggette (there is no bug here as the function where could occur the memory leak is not used in dar (!) ). - updated FAQ - updated man page information about optional argument's syntax to options like -z9 or --zip 9 - avoid calls to textdomain() when --disable-nls is set - updates doc/NOTES - fixed potential memory leakage on some system (to a "new[]" was corresponding a "delete" in place of a "delete[]" (Wesley's patch)) In consequences, for API users, note that the following calls - tools_str2charptr - tools_extract_basename - libdar_str2charptr_noexcept all return a char * pointer which area must be released by the caller using the delete[] operator - partially integrated Wesley's api_tutorial patch (added explanations) -

(Thanks to Jerome Zago) (conform to Filesystem Hierarchy Standard) - added scrambling features (-J and -K options) - added selective compression (-Y and -Z options) - added third state for saved data to keep trace in an extracted catalogue of what is saved in the reference archive (this opens the door to the archive manager) - added the ability to read configuration file (-B option, -B like "batch"). - if a slice name is given in place of a base name, dar proposes to change to the correct base name (strips the extension number and dots). - fixed bug #8 - added dar_manager command-line program - replaced integer types by macro that can be adapted to have correct behavior on 64 bits platform (in particular to read archive from other platforms). from version 1.0.0 to version 1.1.0 - added feature: now ignored directory are not stored at all in the archive unless -D option is used, in which case ignored directory are recorded as empty directory (as it was in 1.0.x) - added support for hard links. Generated archive format version is now 02, but format 01 can still be read, and use as reference. - fixed bug #1 - fixed bug #2 - fixed bug #3 - added feature: restore only more recent file than existing one (-r option) - added feature: support for Extended Attributes (activated at compilation) - added feature: verbose option (-v) with -l (add archive contents) - modified behavior: -l option without -v is no more interactive - added feature: archive integrity test (option -t). CRC have been added in the archive (format 02), thus even without compression Dar is able to detect errors. - added feature: comparison with filesystem (difference) (option -d) - modified behavior: non interactive messages goes to stdout, while those asking user, goes to stderr (all goes to stderr if stdout is used for producing the archive, or for sending orders do dar_slave. - added feature: DAR automatically goes in non interactive mode if no terminal is found on standard input (for example when run from crontab). In that case any question make DAR to abort. - added feature: catalogue extraction to small file: "isolation" (-C option) - added feature: archive produced on stdout when using -c or -C with "-" as filename - added feature: -V option summarizes version of the binary - added feature: additional command "dar_xform" to "re-slice" an archive - added feature: read archive trough a pair of pipes with the help of dar_slave - added feature: long option are now available (see man page) - fixed bug #5 - a lot of speed optimization in algorithm - changed exit codes to positive values in case of error - dar returns an new error code when an operation is partially successful (some filed missed to be saved / restored / tested / compared). - replace the use of vform() method by a customized simple implementation in the ui_printf() routine, this should now allow compilation with gcc-3 - changed long option that used an underscore character (`_') by a dash ('-') - added -O option to have a better behavior when used with non root user - added 'make doc' option in the makefile from version 1.0.2 to version 1.0.3 - bug #5 fixed from version 1.0.1 to version 1.0.2 - bug #2 fixed - bug #3 fixed from version 1.0.0 to version 1.0.1 - correction of few mistakes that lead the compilation to fail with certain C++ compilers - bug #1 fixed. dar-2.5.3/COPYING0000644000175000017430000004330212610404647010253 00000000000000 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. dar-2.5.3/ABOUT-NLS0000644000175000017520000026713312642474463010471 000000000000001 Notes on the Free Translation Project *************************************** Free software is going international! The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that free software will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this `ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU `gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU `gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work on translations can contact the appropriate team. 1.1 INSTALL Matters =================== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU `gettext'. Other packages have their own ways to internationalization, predating GNU `gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU `gettext' functions. Installers may use special options at configuration time for changing the default behaviour. The command: ./configure --disable-nls will _totally_ disable translation of messages. When you already have GNU `gettext' installed on your system and run configure without an option for your new package, `configure' will probably detect the previously built and installed `libintl' library and will decide to use it. If not, you may have to to use the `--with-libintl-prefix' option to tell `configure' where to look for it. Internationalized packages usually have many `po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at `configure' time by using the `--disable-nls' switch, all available translations are installed together with the package. However, the environment variable `LINGUAS' may be set, prior to configuration, to limit the installed set. `LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. 1.2 Using This Package ====================== As a user, if your language has been installed for this package, you only have to set the `LANG' environment variable to the appropriate `LL_CC' combination. If you happen to have the `LC_ALL' or some other `LC_xxx' environment variables set, you should unset them before setting `LANG', otherwise the setting of `LANG' will not have the desired effect. Here `LL' is an ISO 639 two-letter language code, and `CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute `setenv LANG de_DE' (in `csh'), `export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). This can be done from your `.login' or `.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The country code serves to distinguish the dialects. The locale naming convention of `LL_CC', with `LL' denoting the language and `CC' denoting the country, is the one use on systems based on GNU libc. On other systems, some variations of this scheme are used, such as `LL' or `LL_CC.ENCODING'. You can get the list of locales supported by your system for your language by running the command `locale -a | grep '^LL''. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called `LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' for the purpose of message handling, but you still need to have `LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. Special advice for Norwegian users: The language code for Norwegian bokma*l changed from `no' to `nb' recently (in 2003). During the transition period, while some message catalogs for this language are installed under `nb' and some older ones under `no', it's recommended for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and older translations are used. In the `LANGUAGE' environment variable, but not in the `LANG' environment variable, `LL_CC' combinations can be abbreviated as `LL' to denote the language's main dialect. For example, `de' is equivalent to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' (Portuguese as spoken in Portugal) in this context. 1.3 Translating Teams ===================== For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, `http://translationproject.org/', in the "Teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has `-request' appended. For example, speakers of Swedish can send a message to `sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to `coordinator@translationproject.org' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skills are praised more than programming skills, here. 1.4 Available Packages ====================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of June 2010. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

matrix are higher than the number of visible blocks let us expect. This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If June 2010 seems to be old, you may fetch a more recent copy of this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at `http://translationproject.org/extra/matrix.html'. 1.5 Using `gettext' in new packages =================================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU `gettext' in your package. Of course you have to respect the GNU Library General Public License which covers the use of the GNU `gettext' library. This means in particular that even non-free programs can use `libintl' as a shared library, whereas only free software can use `libintl' as a static library or use modified versions of `libintl'. Once the sources are changed appropriately and the setup can handle the use of `gettext' the only thing missing are the translations. The Free Translation Project is also available for packages which are not developed inside the GNU project. Therefore the information given above applies also for every other Free Software Project. Contact `coordinator@translationproject.org' to make the `.pot' files available to the translation teams. dar-2.5.3/po/0000755000175000017520000000000012642474573007726 500000000000000dar-2.5.3/po/fr.po0000644000175000017520000101163112642474573010620 00000000000000# French translations for DAR package. # Copyright (C) 2011 Free Software Foundation, Inc. # This file is distributed under the same license as the DAR package. # Denis Corbin , 2011. # msgid "" msgstr "" "Project-Id-Version: DAR 2.5.0\n" "Report-Msgid-Bugs-To: http://sourceforge.net/tracker/?"

It computes the factorial of the given integer. If compiled without --enable-mode=... option given to configure, it will always (should at least), return the decimal representation of the asked decimal. The problem is more the time it will take to compute it. And using --enable-mode=... you may get a message reporting that an integer overflow has occurred. prime tests if the given number is a prime factor. It relies on infinint.

Source code for dar suite program. libdar directory contains all code of dar that have been moved since version 2.0.0 to a separated library known as libdar. dar_suite directory contains all the rest of the code of dar, which is command-line specific examples directory contains few programs that illustrate the use of infinint, they are built when using --enable-examples with the configure script. testing directory contains a plethora of very simple program that helped validate each C++ module of dar. They are to be used in step by step debugging and in conjunction with variable watch. Theses programs are intended to be used only by developers, they are built when using --enable-examples with the configure script. check contains the global validation routine that are run when calling "make check". Note that running 'make check' may take several days to complete depending on the power of your computer, this is also due to the fact that these routine are very basic but robust, they are not especially optimized for speed. dar-2.5.3/src/dar_suite/0000755000175000017520000000000012642474572012055 500000000000000dar-2.5.3/src/dar_suite/line_tools.cpp0000644000175000017430000005070612641772777014667 00000000000000/*********************************************************************/ // dar - disk archive - a backup/restoration program // Copyright (C) 2002-2052 Denis Corbin // // This program is free software; you can redistribute it and/or // modify it under the terms of the GNU General Public License // as published by the Free Software Foundation; either version 2 // of the License, or (at your option) any later version. // // This program is distributed in the hope that it will be useful, // but WITHOUT ANY WARRANTY; without even the implied warranty of // MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
