Introduction, and Comparison to Other Commandline Flags Libraries

Commandline flags are flags that users specify on the command line when they run an executable. In the command

   fgrep -l -f /var/tmp/foo johannes brahms

-l and -f /var/tmp/foo are the two commandline flags. (johannes and brahms, which don't start with a dash, are commandline arguments.)

Typically, an application lists what flags the user is allowed to pass in, and what arguments they take -- in this example, -l takes no argument, and -f takes a string (in particular, a filename) as an argument. Users can use a library to help parse the commandline and store the flags in some data structure.

Gflags, the commandline flags library used within Google, differs from other libraries, such as getopt(), in that flag definitions can be scattered around the source code, and not just listed in one place such as main(). In practice, this means that a single source-code file will define and use flags that are meaningful to that file. Any application that links in that file will get the flags, and the gflags library will automatically handle that flag appropriately.

There's significant gain in flexibility, and ease of code reuse, due to this technique. However, there is a danger that two files will define the same flag, and then give an error when they're linked together.

The rest of this document describes how to use the commandlineflag library. It's a C++ library, so examples are in C++. However, there is a Python port with the same functionality, and this discussion translates directly to Python.

DEFINE: Defining Flags In Program

Defining a flag is easy: just use the appropriate macro for the type you want the flag to be, as defined at the bottom of gflags/gflags.h. Here's an example file, foo.cc:

   #include <gflags/gflags.h>

   DEFINE_bool(big_menu, true, "Include 'advanced' options in the menu listing");
   DEFINE_string(languages, "english,french,german",
                 "comma-separated list of languages to offer in the 'lang' menu");

DEFINE_bool defines a boolean flag. Here are the types supported:

  • DEFINE_bool: boolean
  • DEFINE_int32: 32-bit integer
  • DEFINE_int64: 64-bit integer
  • DEFINE_uint64: unsigned 64-bit integer
  • DEFINE_double: double
  • DEFINE_string: C++ string

Note that there are no 'complex' types like lists: the "languages" flag in our example is a list of strings, but is defined of type "string", not "list_of_string" or similar. This is by design. We'd rather use only simple types for the flags, and allow for complex, arbitrary parsing routines to parse them, than to try to put the logic inside the flags library proper.

All DEFINE macros take the same three arguments: the name of the flag, its default value, and a 'help' string that describes its use. The 'help' string is displayed when the user runs the application with the --help flag.

You can define a flag in any source-code file in your executable. Only define a flag once! If you want to access a flag in more than one source file, DEFINE it in one file, and DECLARE it in the others. Even better, DEFINE it in foo.cc and DECLARE it in foo.h; then everyone who #includes foo.h can use the flag.

Defining flags in libraries rather than in main() is powerful, but does have some costs. One is that a library might not have a good default value for its flags, for example if the flag holds a filename that might not exist in some environments. To mitigate such problems, you can use flag validators to ensure prompt notification (in the form of a crash) of an invalid flag value.

Note that while most functions in this library are defined in the google namespace, DEFINE_foo (and DECLARE_foo, below), should always be in the global namespace.

Accessing the Flag

All defined flags are available to the program as just a normal variable, with the prefix FLAGS_ prepended. In the above example, the macros define two variables, FLAGS_big_menu (a bool), and FLAGS_languages (a C++ string).

You can read and write to the flag just like any other variable:

   if (FLAGS_consider_made_up_languages)
     FLAGS_languages += ",klingon";   // implied by --consider_made_up_languages
   if (FLAGS_languages.find("finnish") != string::npos)
     HandleFinnish();

You can also get and set flag values via special functions in gflags.h. That's a rarer use case, though.

DECLARE: Using the Flag in a Different File

Accessing a flag in the manner of the previous section only works if the flag was DEFINE-ed at the top of the file. If it wasn't, you'll get an 'unknown variable' error.

The DECLARE_type macro is available when you want to use a flag that's defined in another file. For instance, if I were writing bar.cc but wanted to access the big_menu, flag, I would put this near the top of bar.cc:

   DECLARE_bool(big_menu);

This is functionally equivalent to saying extern FLAGS_big_menu.

Note that such an extern declaration introduces a dependency between your file and the file that defines the big_menu flag: foo.cc, in this case. Such implicit dependencies can be difficult to manage in large projects. For that reason we recommend the following guideline:

If you DEFINE a flag in foo.cc, either don't DECLARE it at all, only DECLARE it in tightly related tests, or only DECLARE it in foo.h.

You should go the do-not-DECLARE route when the flag is only needed by foo.cc, and not in any other file. If you want to modify the value of the flag in the related test file to see if it is functioning as expected, DECLARE it in the foo_test.cc file.

If the flag does span multiple files, DECLARE it in the associated .h file, and make others #include that .h file if they want to access the flag. The #include will make explicit the dependency between the two files. This causes the flag to be a global variable.

RegisterFlagValidator: Sanity-checking Flag Values

After DEFINE-ing a flag, you may optionally register a validator function with the flag. If you do this, after the flag is parsed from the commandline, and whenever its value is changed via a call to SetCommandLineOption(), the validator function is called with the new value as an argument. The validator function should return 'true' if the flag value is valid, and false otherwise. If the function returns false for the new setting of the flag, the flag will retain its current value. If it returns false for the default value, ParseCommandLineFlags will die.

Here is an example use of this functionality:

static bool ValidatePort(const char* flagname, int32 value) {
   if (value > 0 && value < 32768)   // value is ok
     return true;
   printf("Invalid value for --%s: %d\n", flagname, (int)value);
   return false;
}
DEFINE_int32(port, 0, "What port to listen on");
static const bool port_dummy = RegisterFlagValidator(&FLAGS_port, &ValidatePort);

By doing the registration at global initialization time (right after the DEFINE), we ensure that the registration happens before the commandline is parsed at the beginning of main().

RegisterFlagValidator() returns true if the registration is successful. It return false if the registration fails because a) the first argument does not refer to a commandline flag, or b) a different validator has already been registered for this flag.

Putting It Together: How to Set Up Flags

The final piece is the one that tells the executable to process the commandline flags, and set the FLAGS_* variables to the appropriate, non-default value based on what is seen on the commandline. This is equivalent to the getopt() call in the getopt library, but has much less overhead to use. In fact, it's just a single function call:

   google::ParseCommandLineFlags(&argc, &argv, true);

Usually, this code is at the beginning of main(). argc and argv are exactly as passed in to main(). This routine might modify them, which is why pointers to them are passed in.

The last argument is called "remove_flags". If true, then ParseCommandLineFlags removes the flags and their arguments from argv, and modifies argc appropriately. In this case, after the function call, argv will hold only commandline arguments, and not commandline flags.

If, on the other hand, remove_flags is false, then ParseCommandLineFlags will leave argc unchanged, but will rearrange the arguments in argv so that the flags are all at the beginning. For example, if the input is "/bin/foo" "arg1" "-q" "arg2" (which is legal but weird), the function will rearrange argv so it reads "/bin/foo", "-q", "arg1", "arg2". In this case, ParseCommandLineFlags returns the index into argv that holds the first commandline argument: that is, the index past the last flag. (In this example, it would return 2, since argv[2] points to arg1.)

In either case, the FLAGS_* variables are modified based on what was passed in on the commandline.

Setting Flags on the Command Line

The reason you make something a flag instead of a compile-time constant, is so users can specify a non-default value on the commandline. Here's how they might do it for an application that links in foo.cc:

   app_containing_foo --nobig_menu -languages="chinese,japanese,korean" ...

This sets FLAGS_big_menu = false; and FLAGS_languages = "chinese,japanese,korean", when ParseCommandLineFlags is run.

Note the atypical syntax for setting a boolean flag to false: putting "no" in front of its name. There's a fair bit of flexibility to how flags may be specified. Here's an example of all the ways to specify the "languages" flag:

  • app_containing_foo --languages="chinese,japanese,korean"
  • app_containing_foo -languages="chinese,japanese,korean"
  • app_containing_foo --languages "chinese,japanese,korean"
  • app_containing_foo -languages "chinese,japanese,korean"

For boolean flags, the possibilities are slightly different:

  • app_containing_foo --big_menu
  • app_containing_foo --nobig_menu
  • app_containing_foo --big_menu=true
  • app_containing_foo --big_menu=false

(as well as the single-dash variant on all of these).

Despite this flexibility, we recommend using only a single form: --variable=value for non-boolean flags, and --variable/--novariable for boolean flags. This consistency will make your code more readable, and is also the format required for certain special-use cases like flagfiles.

It is a fatal error to specify a flag on the commandline that has not been DEFINED somewhere in the executable. If you need that functionality for some reason -- say you want to use the same set of flags for several executables, but not all of them DEFINE every flag in your list -- you can specify --undefok to suppress the error.

As in getopt(), -- by itself will terminate flags processing. So in foo -f1 1 -- -f2 2, f1 is considered a flag, but -f2 is not.

If a flag is specified more than once, only the last specification is used; the others are ignored.

Note that flags do not have single-letter synonyms, like they do in the getopt library, nor do we allow "combining" flags behind a single dash, as in ls -la.

Changing the Default Flag Value

Sometimes a flag is defined in a library, and you want to change its default value in one application but not others. It's simple to do this: just assign a new value to the flag in main(), before calling ParseCommandLineFlags():

   DECLARE_bool(lib_verbose);   // mylib has a lib_verbose flag, default is false
   int main(int argc, char** argv) {
     FLAGS_lib_verbose = true;  // in my app, I want a verbose lib by default
     ParseCommandLineFlags(...);
   }

For this application, users can still set the flag value on the commandline, but if they do not, the flag's value will default to true.

Special Flags

There are a few flags defined by the commandlineflags module itself, and are available to all applications that use commandlineflags. These fall into three categories. First are the 'reporting' flags that, when found, cause the application to print some information about itself and exit.

--help shows all flags from all files, sorted by file and then by name; shows the flagname, its default value, and its help string
--helpfull same as -help, but unambiguously asks for all flags (in case -help changes in the future)
--helpshort shows only flags for the file with the same name as the executable (usually the one containing main())
--helpxml like --help, but output is in xml for easier parsing
--helpon=FILE   shows only flags defined in FILE.*
--helpmatch=S shows only flags defined in *S*.*
--helppackage shows flags defined in files in same directory as main()
--version prints version info for the executable

Second are the flags that affect how other flags are parsed.

--undefok=flagname,flagname,... for those names listed as the argument to --undefok, suppress the normal error-exit that occurs when --name is seen on the commandline, but name has not been DEFINED anywhere in the application

Third are the 'recursive' flags, that cause other flag values to be set: --fromenv, --tryfromenv, --flagfile. These are described below in more detail.

--fromenv

--fromenv=foo,bar says to read the values for the foo and bar flags from the environment. In concert with this flag, you must actually set the values in the environment, via a line like one of the two below:

   export FLAGS_foo=xxx; export FLAGS_bar=yyy   # sh
   setenv FLAGS_foo xxx; setenv FLAGS_bar yyy   # tcsh

This is equivalent to specifying --foo=xxx, --bar=yyy on the commandline.

Note it is a fatal error to say --fromenv=foo if foo is not DEFINED somewhere in the application. (Though you can suppress this error via --undefok=foo, just like for any other flag.)

It is also a fatal error to say --fromenv=foo if FLAGS_foo is not actually defined in the environment.

--tryfromenv

--tryfromenv is exactly like --fromenv, except it is not a fatal error to say --tryfromenv=foo if FLAGS_foo is not actually defined in the environment. Instead, in such cases, FLAGS_foo just keeps its default value as specified in the application.

Note it is still an error to say --tryfromenv=foo if foo is not DEFINED somewhere in the application.

--flagfile

--flagfile=f tells the commandlineflags module to read the file f, and to run all the flag-assignments found in that file as if these flags had been specified on the commandline.

In its simplest form, f should just be a list of flag assignments, one per line. Unlike on the commandline, the equals sign separating a flagname from its argument is required for flagfiles. An example flagfile, /tmp/myflags:

--nobig_menus
--languages=english,french

With this flagfile, the following two lines are equivalent:

   ./myapp --foo --nobig_menus --languages=english,french --bar
   ./myapp --foo --flagfile=/tmp/myflags --bar

Note that many errors are silently suppressed in flagfiles. In particular, unrecognized flagnames are silently ignored, as are flags that are missing a required value (e.g., a flagfile that just says --languages).

The general format of a flagfile is a bit more complicated than the simple, common case above. It is: a sequence of filenames, one per line, followed by a sequence of flags, one per line, repeated as many times as desired. Filenames in a flagfile can use wildcards (* and ?), and the sequence of flags located after a sequence of filenames is processed only if the current executable's name matches one of the filenames. It is possible to start the flagfile with a sequence of flags instead of a sequence of filenames; if such a sequence of flags is present, these flags are applied to the current executable no matter what it is.

Lines that start with a # are ignored as comments. Leading whitespace is also ignored in flagfiles, as are blank lines.

It is possible for a flagfile to use the --flagfile flag to include another flagfile.

Flags are always processed in the expected order. That is, processing begins by examining the flags specified directly on the command line. If a flagfile is specified, its contents are processed, and then processing continues with remaining flags from the command line.

The API

In addition to accessing FLAGS_foo directly, it is possible to access the flags programmatically, through an API. It is also possible to access information about a flag, such as its default value and help-string. A FlagSaver makes it easy to modify flags and then automatically undo the modifications later. Finally, there are somewhat unrelated, but useful, routines to easily access parts of argv outside main, including the program name (argv[0]).

For more information about these routines, and other useful helper methods such as google::SetUsageMessage() and google::SetVersionString, see gflags.h.

Miscellaneous Notes

If your application has code like this:

   #define STRIP_FLAG_HELP 1    // this must go before the #include!
   #include <gflags/gflags.h>

we will remove the help messages from the compiled source. This can reduce the size of the resulting binary somewhat, and may also be useful for security reasons.

It has increased flexibility, including built-in support for C++ types like string, and the ability to define flags in the source file in which they're used. gflags-2.0/packages/deb/compat0000644000076400116100000000000211710105677013252 000000000000004 gflags-2.0/packages/deb/libgflags-dev.dirs0000644000076400116100000000011411710105677015441 00000000000000usr/lib usr/lib/pkgconfig usr/include usr/include/google usr/include/gflags gflags-2.0/packages/deb/changelog0000644000076400116100000000661611710105700013722 00000000000000gflags (2.0-1) unstable; urgency=low * New upstream release. -- Google Inc. and others Wed, 25 Jan 2012 15:09:14 -0800 gflags (1.7-1) unstable; urgency=low * New upstream release. -- Google Inc.

In the same vein, we have to worry about // flag access in global destructors, so FlagRegisterer has to be // careful never to destroy the flag-values it constructs. // // Note that when we define a flag variable FLAGS_, we also // preemptively define a junk variable, FLAGS_no. This is to // cause a link-time error if someone tries to define 2 flags with // names like "logging" and "nologging". We do this because a bool // flag FLAG can be set from the command line to true with a "-FLAG" // argument, and to false with a "-noFLAG" argument, and so this can // potentially avert confusion. // // We also put flags into their own namespace. It is purposefully // named in an opaque way that people should have trouble typing // directly.

If this // flag is empty, nothing happens here. If it contains a string, // however, then HandleCommandLineCompletions() will hijack the // process, attempting to identify the intention behind this // completion. Regardless of the outcome of this deduction, the // process will be terminated, similar to --helpshort flag // handling. // // ** Overview of Bash completions: // Bash can be told to programatically determine completions for the // current 'cursor word'. It does this by (in this case) invoking a // command with some additional arguments identifying the command // being executed, the word being completed, and the previous word // (if any). Bash then expects a sequence of output lines to be // printed to stdout. If these lines all contain a common prefix // longer than the cursor word, bash will replace the cursor word // with that common prefix, and display nothing. If there isn't such // a common prefix, bash will display the lines in pages using 'more'. // // ** Strategy taken for command line completions: // If we can deduce either the exact flag intended, or a common flag // prefix, we'll output exactly that. Otherwise, if information // must be displayed to the user, we'll take the opportunity to add // some helpful information beyond just the flag name (specifically, // we'll include the default flag value and as much of the flag's // description as can fit on a single terminal line width, as specified // by the flag --tab_completion_columns). Furthermore, we'll try to // make bash order the output such that the most useful or relevent // flags are the most likely to be shown at the top. // // ** Additional features: // To assist in finding that one really useful flag, substring matching // was implemented. Before pressing a to get completion for the // current word, you can append one or more '?' to the flag to do // substring matching. Here's the semantics: // --foo Show me all flags with names prefixed by 'foo' // --foo? Show me all flags with 'foo' somewhere in the name // --foo?? Same as prior case, but also search in module // definition path for 'foo' // --foo??? Same as prior case, but also search in flag // descriptions for 'foo' // Finally, we'll trim the output to a relatively small number of // flags to keep bash quiet about the verbosity of output. If one // really wanted to see all possible matches, appending a '+' to the // search word will force the exhaustive list of matches to be printed. // // ** How to have bash accept completions from a binary: // Bash requires that it be informed about each command that programmatic // completion should be enabled for. Example addition to a .bashrc // file would be (your path to gflags_completions.sh file may differ): /* $ complete -o bashdefault -o default -o nospace -C \ '/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \ time env binary_name another_binary [...] */ // This would allow the following to work: // $ /path/to/binary_name --vmodule // Or: // $ ./bin/path/another_binary --gfs_u // (etc) // // Sadly, it appears that bash gives no easy way to force this behavior for // all commands. That's where the "time" in the above example comes in. // If you haven't specifically added a command to the list of completion // supported commands, you can still get completions by prefixing the // entire command with "env". // $ env /some/brand/new/binary --vmod // Assuming that "binary" is a newly compiled binary, this should still // produce the expected completion output. #ifndef BASE_COMMANDLINEFLAGS_COMPLETIONS_H_ #define BASE_COMMANDLINEFLAGS_COMPLETIONS_H_ // Annoying stuff for windows -- makes sure clients can import these functions // // NOTE: all functions below MUST have an explicit 'extern' before // them.

In the same vein, we have to worry about // flag access in global destructors, so FlagRegisterer has to be // careful never to destroy the flag-values it constructs. // // Note that when we define a flag variable FLAGS_, we also // preemptively define a junk variable, FLAGS_no. This is to // cause a link-time error if someone tries to define 2 flags with // names like "logging" and "nologging". We do this because a bool // flag FLAG can be set from the command line to true with a "-FLAG" // argument, and to false with a "-noFLAG" argument, and so this can // potentially avert confusion. // // We also put flags into their own namespace.

The idea is that DEFINE puts the flag in the weird // namespace, and DECLARE imports the flag from there into the current // namespace. The net result is to force people to use DECLARE to get // access to a flag, rather than saying "extern bool FLAGS_whatever;" // or some such instead.

If this // flag is empty, nothing happens here. If it contains a string, // however, then HandleCommandLineCompletions() will hijack the // process, attempting to identify the intention behind this // completion. Regardless of the outcome of this deduction, the // process will be terminated, similar to --helpshort flag // handling. // // ** Overview of Bash completions: // Bash can be told to programatically determine completions for the // current 'cursor word'. It does this by (in this case) invoking a // command with some additional arguments identifying the command // being executed, the word being completed, and the previous word // (if any). Bash then expects a sequence of output lines to be // printed to stdout. If these lines all contain a common prefix // longer than the cursor word, bash will replace the cursor word // with that common prefix, and display nothing. If there isn't such // a common prefix, bash will display the lines in pages using 'more'. // // ** Strategy taken for command line completions: // If we can deduce either the exact flag intended, or a common flag // prefix, we'll output exactly that. Otherwise, if information // must be displayed to the user, we'll take the opportunity to add // some helpful information beyond just the flag name (specifically, // we'll include the default flag value and as much of the flag's // description as can fit on a single terminal line width, as specified // by the flag --tab_completion_columns). Furthermore, we'll try to // make bash order the output such that the most useful or relevent // flags are the most likely to be shown at the top. // // ** Additional features: // To assist in finding that one really useful flag, substring matching // was implemented. Before pressing a to get completion for the // current word, you can append one or more '?' to the flag to do // substring matching. Here's the semantics: // --foo Show me all flags with names prefixed by 'foo' // --foo? Show me all flags with 'foo' somewhere in the name // --foo?? Same as prior case, but also search in module // definition path for 'foo' // --foo??? Same as prior case, but also search in flag // descriptions for 'foo' // Finally, we'll trim the output to a relatively small number of // flags to keep bash quiet about the verbosity of output. If one // really wanted to see all possible matches, appending a '+' to the // search word will force the exhaustive list of matches to be printed. // // ** How to have bash accept completions from a binary: // Bash requires that it be informed about each command that programmatic // completion should be enabled for. Example addition to a .bashrc // file would be (your path to gflags_completions.sh file may differ): /* $ complete -o bashdefault -o default -o nospace -C \ '/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \ time env binary_name another_binary [...] */ // This would allow the following to work: // $ /path/to/binary_name --vmodule // Or: // $ ./bin/path/another_binary --gfs_u // (etc) // // Sadly, it appears that bash gives no easy way to force this behavior for // all commands. That's where the "time" in the above example comes in. // If you haven't specifically added a command to the list of completion // supported commands, you can still get completions by prefixing the // entire command with "env". // $ env /some/brand/new/binary --vmod // Assuming that "binary" is a newly compiled binary, this should still // produce the expected completion output. #ifndef BASE_COMMANDLINEFLAGS_COMPLETIONS_H_ #define BASE_COMMANDLINEFLAGS_COMPLETIONS_H_ // Annoying stuff for windows -- makes sure clients can import these functions // // NOTE: all functions below MUST have an explicit 'extern' before // them.

If this // flag is empty, nothing happens here. If it contains a string, // however, then HandleCommandLineCompletions() will hijack the // process, attempting to identify the intention behind this // completion. Regardless of the outcome of this deduction, the // process will be terminated, similar to --helpshort flag // handling. // // ** Overview of Bash completions: // Bash can be told to programatically determine completions for the // current 'cursor word'. It does this by (in this case) invoking a // command with some additional arguments identifying the command // being executed, the word being completed, and the previous word // (if any). Bash then expects a sequence of output lines to be // printed to stdout. If these lines all contain a common prefix // longer than the cursor word, bash will replace the cursor word // with that common prefix, and display nothing. If there isn't such // a common prefix, bash will display the lines in pages using 'more'. // // ** Strategy taken for command line completions: // If we can deduce either the exact flag intended, or a common flag // prefix, we'll output exactly that. Otherwise, if information // must be displayed to the user, we'll take the opportunity to add // some helpful information beyond just the flag name (specifically, // we'll include the default flag value and as much of the flag's // description as can fit on a single terminal line width, as specified // by the flag --tab_completion_columns). Furthermore, we'll try to // make bash order the output such that the most useful or relevent // flags are the most likely to be shown at the top. // // ** Additional features: // To assist in finding that one really useful flag, substring matching // was implemented. Before pressing a to get completion for the // current word, you can append one or more '?' to the flag to do // substring matching. Here's the semantics: // --foo Show me all flags with names prefixed by 'foo' // --foo? Show me all flags with 'foo' somewhere in the name // --foo?? Same as prior case, but also search in module // definition path for 'foo' // --foo??? Same as prior case, but also search in flag // descriptions for 'foo' // Finally, we'll trim the output to a relatively small number of // flags to keep bash quiet about the verbosity of output. If one // really wanted to see all possible matches, appending a '+' to the // search word will force the exhaustive list of matches to be printed. // // ** How to have bash accept completions from a binary: // Bash requires that it be informed about each command that programmatic // completion should be enabled for.

Before you use this module, please give the // name of your internal namespace for this module. Or, if you want // to expose it, you'll want to move it to the Google namespace. We // cannot put this class in global namespace because there can be some // problems when we have multiple versions of Mutex in each shared object. // // NOTE: by default, we have #ifdef'ed out the TryLock() method. // This is for two reasons: // 1) TryLock() under Windows is a bit annoying (it requires a // #define to be defined very early). // 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG // mode. // If you need TryLock(), and either these two caveats are not a // problem for you, or you're willing to work around them, then // feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs // in the code below. // // CYGWIN NOTE: Cygwin support for rwlock seems to be buggy: // http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html // Because of that, we might as well use windows locks for // cygwin. They seem to be more reliable than the cygwin pthreads layer. // // TRICKY IMPLEMENTATION NOTE: // This class is designed to be safe to use during // dynamic-initialization -- that is, by global constructors that are // run before main() starts. The issue in this case is that // dynamic-initialization happens in an unpredictable order, and it // could be that someone else's dynamic initializer could call a // function that tries to acquire this mutex -- but that all happens // before this mutex's constructor has run. (This can happen even if // the mutex and the function that uses the mutex are in the same .cc // file.) Basically, because Mutex does non-trivial work in its // constructor, it's not, in the naive implementation, safe to use // before dynamic initialization has run on it. // // The solution used here is to pair the actual mutex primitive with a // bool that is set to true when the mutex is dynamically initialized. // (Before that it's false.) Then we modify all mutex routines to // look at the bool, and not try to lock/unlock until the bool makes // it to true (which happens after the Mutex constructor has run.) // // This works because before main() starts -- particularly, during // dynamic initialization -- there are no threads, so a) it's ok that // the mutex operations are a no-op, since we don't need locking then // anyway; and b) we can be quite confident our bool won't change // state between a call to Lock() and a call to Unlock() (that would // require a global constructor in one translation unit to call Lock() // and another global constructor in another translation unit to call // Unlock() later, which is pretty perverse). // // That said, it's tricky, and can conceivably fail; it's safest to // avoid trying to acquire a mutex in a global constructor, if you // can. One way it can fail is that a really smart compiler might // initialize the bool to true at static-initialization time (too // early) rather than at dynamic-initialization time. To discourage // that, we set is_safe_ to true in code (not the constructor // colon-initializer) and set it to true via a function that always // evaluates to true, but that the compiler can't know always // evaluates to true. This should be good enough. // // A related issue is code that could try to access the mutex // after it's been destroyed in the global destructors (because // the Mutex global destructor runs before some other global // destructor, that tries to acquire the mutex). The way we // deal with this is by taking a constructor arg that global // mutexes should pass in, that causes the destructor to do no // work. We still depend on the compiler not doing anything // weird to a Mutex's memory after it is destroyed, but for a // static global variable, that's pretty safe. #ifndef GOOGLE_MUTEX_H_ #define GOOGLE_MUTEX_H_ #include "config.h" // to figure out pthreads support #if defined(NO_THREADS) typedef int MutexType; // to keep a lock-count #elif defined(_WIN32) || defined(__CYGWIN32__) || defined(__CYGWIN64__) # ifndef WIN32_LEAN_AND_MEAN # define WIN32_LEAN_AND_MEAN // We only need minimal includes # endif # ifndef NOMINMAX # define NOMINMAX // Don't want windows to override min()/max() # endif # ifdef GMUTEX_TRYLOCK // We need Windows NT or later for TryEnterCriticalSection().

Here's how everything fits together // // * FlagRegistry owns CommandLineFlags owns FlagValue. // * FlagSaver holds a FlagRegistry (saves it at construct time, // restores it at destroy time). // * CommandLineFlagParser lives outside that hierarchy, but works on // CommandLineFlags (modifying the FlagValues). // * Free functions like SetCommandLineOption() work via one of the // above (such as CommandLineFlagParser). // // In more detail: // // -- The main classes that hold flag data: // // FlagValue holds the current value of a flag. It's // pseudo-templatized: every operation on a FlagValue is typed. It // also deals with storage-lifetime issues (so flag values don't go // away in a destructor), which is why we need a whole class to hold a // variable's value. // // CommandLineFlag is all the information about a single command-line // flag. It has a FlagValue for the flag's current value, but also // the flag's name, type, etc. // // FlagRegistry is a collection of CommandLineFlags. There's the // global registry, which is where flags defined via DEFINE_foo() // live. But it's possible to define your own flag, manually, in a // different registry you create. (In practice, multiple registries // are used only by FlagSaver). // // A given FlagValue is owned by exactly one CommandLineFlag. A given // CommandLineFlag is owned by exactly one FlagRegistry. FlagRegistry // has a lock; any operation that writes to a FlagValue or // CommandLineFlag owned by that registry must acquire the // FlagRegistry lock before doing so. // // --- Some other classes and free functions: // // CommandLineFlagInfo is a client-exposed version of CommandLineFlag. // Once it's instantiated, it has no dependencies or relationships // with any other part of this file. // // FlagRegisterer is the helper class used by the DEFINE_* macros to // allow work to be done at global initialization time. // // CommandLineFlagParser is the class that reads from the commandline // and instantiates flag values based on that. It needs to poke into // the innards of the FlagValue->CommandLineFlag->FlagRegistry class // hierarchy to do that. It's careful to acquire the FlagRegistry // lock before doing any writing or other non-const actions. // // GetCommandLineOption is just a hook into registry routines to // retrieve a flag based on its name. SetCommandLineOption, on the // other hand, hooks into CommandLineFlagParser.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 6. Often, you can also type `make uninstall' to remove the installed files again. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. gflags-2.0/NEWS0000644000076400116100000001512311710105700010230 00000000000000== 25 January 2012 == I've just released gflags 2.0. The `google-gflags` project has been renamed to `gflags`. I (csilvers) am stepping down as maintainer, to be replaced by Andreas Schuh. Welcome to the team, Andreas! I've seen the energy you have around gflags and the ideas you have for the project going forward, and look forward to having you on the team. I bumped the major version number up to 2 to reflect the new community ownership of the project. All the [http://gflags.googlecode.com/svn/tags/gflags-2.0/ChangeLog changes] are related to the renaming. There are no functional changes from gflags 1.7. In particular, I've kept the code in the namespace `google`, though in a future version it should be renamed to `gflags`. I've also kept the `/usr/local/include/google/` subdirectory as synonym of `/usr/local/include/gflags/`, though the former name has been obsolete for some time now. === 18 January 2011 === The `google-gflags` Google Code page has been renamed to `gflags`, in preparation for the project being renamed to `gflags`. In the coming weeks, I'll be stepping down as maintainer for the gflags project, and as part of that Google is relinquishing ownership of the project; it will now be entirely community run. The name change reflects that shift. === 20 December 2011 === I've just released gflags 1.7. This is a minor release; the major change is that `CommandLineFlagInfo` now exports the address in memory where the flag is located. There has also been a bugfix involving very long --help strings, and some other minor [http://code.google.com/p/google-gflags/source/browse/tags/gflags-1.7/ChangeLog changes]. === 29 July 2011 === I've just released gflags 1.6. The major new feature in this release is support for setting version info, so that --version does something useful. One minor change has required bumping the library number: `ReparseCommandlineFlags` now returns `void` instead of `int` (the int return value was always meaningless). Though I doubt anyone ever used this (meaningless) return value, technically it's a change to the ABI that requires a version bump. A bit sad. There's also a procedural change with this release: I've changed the internal tools used to integrate Google-supplied patches for gflags into the opensource release. These new tools should result in more frequent updates with better change descriptions. They will also result in future `ChangeLog` entries being much more verbose (for better or for worse). See the [http://code.google.com/p/google-gflags/source/browse/tags/gflags-1.6/ChangeLog ChangeLog] for a full list of changes for this release. === 24 January 2011 === I've just released gflags 1.5. This release has only minor changes from 1.4, including some slightly better reporting in --help, and an new memory-cleanup function that can help when running gflags-using libraries under valgrind. The major change is to fix up the macros (`DEFINE_bool` and the like) to work more reliably inside namespaces. If you have not had a problem with these macros, and don't need any of the other changes described, there is no need to upgrade. See the [http://code.google.com/p/google-gflags/source/browse/tags/gflags-1.5/ChangeLog ChangeLog] for a full list of changes for this release. === 11 October 2010 === I've just released gflags 1.4. This release has only minor changes from 1.3, including some documentation tweaks and some work to make the library smaller. If 1.3 is working well for you, there's no particular reason to upgrade. === 4 January 2010 === I've just released gflags 1.3. gflags now compiles under MSVC, and all tests pass. I *really* never thought non-unix-y Windows folks would want gflags, but at least some of them do. The major news, though, is that I've separated out the python package into its own library, [http://code.google.com/p/python-gflags python-gflags]. If you're interested in the Python version of gflags, that's the place to get it now. === 10 September 2009 == I've just released gflags 1.2. The major change from gflags 1.1 is it now compiles under MinGW (as well as cygwin), and all tests pass. I never thought Windows folks would want unix-style command-line flags, since they're so different from the Windows style, but I guess I was wrong! The other changes are minor, such as support for --htmlxml in the python version of gflags. === 15 April 2009 === I've just released gflags 1.1. It has only minor changes fdrom gflags 1.0 (see the [http://code.google.com/p/google-gflags/source/browse/tags/gflags-1.1/ChangeLog ChangeLog] for details). The major change is that I moved to a new system for creating .deb and .rpm files. This allows me to create x86_64 deb and rpm files. In the process of moving to this new system, I noticed an inconsistency: the tar.gz and .rpm files created libraries named libgflags.so, but the deb file created libgoogle-gflags.so. I have fixed the deb file to create libraries like the others. I'm no expert in debian packaging, but I believe this has caused the package name to change as well. Please let me know (at [mailto:google-gflags@googlegroups.com google-gflags@googlegroups.com]) if this causes problems for you -- especially if you know of a fix! I would be happy to change the deb packages to add symlinks from the old library name to the new (libgoogle-gflags.so -> libgflags.so), but that is beyond my knowledge of how to make .debs. If you've tried to install a .rpm or .deb and it doesn't work for you, let me know. I'm excited to finally have 64-bit package files, but there may still be some wrinkles in the new system to iron out. ===1 October 2008=== gflags 1.0rc2 was out for a few weeks without any issues, so gflags 1.0 is now released. This is much like gflags 0.9. The major change is that the .h files have been moved from `/usr/include/google` to `/usr/include/gflags`. While I have backwards-compatibility forwarding headeds in place, please rewrite existing code to say {{{ #include }}} instead of {{{ #include }}} I've kept the default namespace to google. You can still change with with the appropriate flag to the configure script (`./configure --help` to see the flags). If you have feedback as to whether the default namespace should change to gflags, which would be a non-backwards-compatible change, send mail to `google-gflags@googlegroups.com`! Version 1.0 also has some neat new features, like support for bash commandline-completion of help flags. See the [http://code.google.com/p/google-gflags/source/browse/tags/gflags-1.0rc2/ChangeLog ChangeLog] for more details. If I don't hear any bad news for a few weeks, I'll release 1.0-final. gflags-2.0/README_windows.txt0000644000076400116100000000232011710105677013011 00000000000000You can compile this under Windows, if you want. The solution file (for VC 7.1 and later) is in this directory. I've been told the following steps work to compile this under win64: 1) Open the provided solution file 2) Click on the Win32 target (on the right of Debug/Release) 3) Choose Configuration Manager 4) In Active Solution Platforms, choose New... 5) In "Type of select the new platform", choose x64. In "Copy settings from:" choose Win32. 6) Ok and then Close I don't know very much about how to install DLLs on Windows, so you'll have to figure out that part for yourself. If you choose to just re-use the existing .sln, make sure you set the IncludeDir's appropriately! Look at the properties for libgflags.dll. You can also create a static library of gflags. To do this, add /D GFLAGS_DLL_DECL= /D GFLAGS_DLL_DECLARE_FLAG= /D GFLAGS_DLL_DEFINE_FLAG= to the compile line of every gflags .cc file. If you create a static library that *uses* flags (that is, DEFINEs or DECLAREs flags), you will need to add the following to every .cc file that defines or declares a flag (it's safe to add them to every .cc file in your project): /D GFLAGS_DLL_DECLARE_FLAG= /D GFLAGS_DLL_DEFINE_FLAG= gflags-2.0/Makefile.am0000644000076400116100000002310111710105677011575 00000000000000## Process this file with automake to produce Makefile.in # Make sure that when we re-make ./configure, we get the macros we need ACLOCAL_AMFLAGS = -I m4 # This is so we can #include AM_CPPFLAGS = -I$(top_srcdir)/src # This is mostly based on configure options AM_CXXFLAGS = # These are good warnings to turn on by default, if GCC AM_CXXFLAGS += -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare endif # The -no-undefined flag allows libtool to generate shared libraries for # Cygwin and MinGW.
