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.

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 <TAB> 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<TAB> Show me all flags with names prefixed by 'foo' -// --foo?<TAB> Show me all flags with 'foo' somewhere in the name -// --foo??<TAB> Same as prior case, but also search in module -// definition path for 'foo' -// --foo???<TAB> 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<TAB> -// Or: -// $ ./bin/path/another_binary --gfs_u<TAB> -// (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<TAB> -// Assuming that "binary" is a newly compiled binary, this should still -// produce the expected completion output. - - -#ifndef GFLAGS_COMPLETIONS_H_ -#define GFLAGS_COMPLETIONS_H_ - -namespace google { - -extern void HandleCommandLineCompletions(void); - -} - -#endif // GFLAGS_COMPLETIONS_H_ diff --git a/extern/libmv/third_party/gflags/gflags/gflags_declare.h b/extern/libmv/third_party/gflags/gflags/gflags_declare.h deleted file mode 100644 index 9b85f46cfdc..00000000000 --- a/extern/libmv/third_party/gflags/gflags/gflags_declare.h +++ /dev/null @@ -1,141 +0,0 @@ -// Copyright (c) 1999, Google Inc. -// All rights reserved. -// -// Redistribution and use in source and binary forms, with or without -// modification, are permitted provided that the following conditions are -// met: -// -// * Redistributions of source code must retain the above copyright -// notice, this list of conditions and the following disclaimer. -// * Redistributions in binary form must reproduce the above -// copyright notice, this list of conditions and the following disclaimer -// in the documentation and/or other materials provided with the -// distribution. -// * Neither the name of Google Inc. nor the names of its -// contributors may be used to endorse or promote products derived from -// this software without specific prior written permission. -// -// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -// A PARTICULAR PURPOSE ARE DISCLAIMED.

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 GFLAGS_MUTEX_H_ -#define GFLAGS_MUTEX_H_ - -#include "gflags_declare.h" // to figure out pthreads support - -#if defined(NO_THREADS) - typedef int MutexType; // to keep a lock-count -#elif defined(OS_WINDOWS) -# 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().

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.
