// The intention of this file is to make possible using GMock actions in
// all of its syntactic beauty. Classes and helper functions can be used as
// more generic variants of Task and Callback classes (see base/task.h)
// Mutant supports both pre-bound arguments (like Task) and call-time
// arguments (like Callback) - hence the name. :-)
//
// DispatchToMethod/Function supports two sets of arguments: pre-bound (P) and
// call-time (C). The arguments as well as the return type are templatized.
// DispatchToMethod/Function will also try to call the selected method or
// function even if provided pre-bound arguments does not match exactly with
// the function signature hence the X1, X2 ... XN parameters in CreateFunctor.
// DispatchToMethod will try to invoke method that may not belong to the
// object's class itself but to the object's class base class.
//
// Additionally you can bind the object at calltime by binding a pointer to
// pointer to the object at creation time - before including this file you
// have to #define GMOCK_MUTANT_INCLUDE_LATE_OBJECT_BINDING.
//
// TODO(stoyan): It's yet not clear to me should we use T& and T&* instead
// of T* and T** when we invoke CreateFunctor to match the EXPECT_CALL style.
//
//
// Sample usage with gMock:
//
// struct Mock : public ObjectDelegate {
// MOCK_METHOD2(string, OnRequest(int n, const string& request));
// MOCK_METHOD1(void, OnQuit(int exit_code));
// MOCK_METHOD2(void, LogMessage(int level, const string& message));
//
// string HandleFlowers(const string& reply, int n, const string& request) {
// string result = SStringPrintf("In request of %d %s ", n, request);
// for (int i = 0; i < n; ++i) result.append(reply)
// return result;
// }
//
// void DoLogMessage(int level, const string& message) {
// }
//
// void QuitMessageLoop(int seconds) {
// MessageLoop* loop = MessageLoop::current();
// loop->PostDelayedTask(FROM_HERE, MessageLoop::QuitClosure(),
// 1000 * seconds);
// }
// };
//
// Mock mock;
// // Will invoke mock.HandleFlowers("orchids", n, request)
// // "orchids" is a pre-bound argument, and <n> and <request> are call-time
// // arguments - they are not known until the OnRequest mock is invoked.

How to update platform configuration files:
The gen/ directory contains pre-generated configuration header files.
Historically, all operating systems and architectures have generated
similar configurations except for Windows. This is why there's only
posix and win directories below gen/.
When rolling gflags to a newer version, it's a good idea to check if
new configuration files needs to be generated as well.
Do this by running ./configure in the newly checked out version of
gflags. Then diff the generated files with the ones below gen/.
If you notice a diff, update the files with the updated ones.
If you suspect platform dependend changes other than Windows, you'll
have to checkout gflags on the other platforms as well and run
./configure there too.

//
// This is the file that should be included by any file which declares
// or defines a command line flag or wants to parse command line flags
// or print a program usage message (which will include information about
// flags). Executive summary, in the form of an example foo.cc file:
//
// #include "foo.h" // foo.h has a line "DECLARE_int32(start);"
// #include "validators.h" // hypothetical file defining ValidateIsFile()
//
// DEFINE_int32(end, 1000, "The last record to read");
//
// DEFINE_string(filename, "my_file.txt", "The file to read");
// // Crash if the specified file does not exist.
// static bool dummy = RegisterFlagValidator(&FLAGS_filename,
// &ValidateIsFile);
//
// DECLARE_bool(verbose); // some other file has a DEFINE_bool(verbose, ...)
//
// void MyFunc() {
// if (FLAGS_verbose) printf("Records %d-%d\n", FLAGS_start, FLAGS_end);
// }
//
// Then, at the command-line:
// ./foo --noverbose --start=5 --end=100

// --- A note about thread-safety:
//
// We describe many functions in this routine as being thread-hostile,
// thread-compatible, or thread-safe. Here are the meanings we use:
//
// thread-safe: it is safe for multiple threads to call this routine
// (or, when referring to a class, methods of this class)
// concurrently.
// thread-hostile: it is not safe for multiple threads to call this
// routine (or methods of this class) concurrently. In gflags,
// most thread-hostile routines are intended to be called early in,
// or even before, main() -- that is, before threads are spawned.
// thread-compatible: it is safe for multiple threads to read from
// this variable (when applied to variables), or to call const
// methods of this class (when applied to classes), as long as no
// other thread is writing to the variable or calling non-const
// methods of this class.

// To actually define a flag in a file, use DEFINE_bool,
// DEFINE_string, etc. at the bottom of this file. You may also find
// it useful to register a validator with the flag. This ensures that
// when the flag is parsed from the commandline, or is later set via
// SetCommandLineOption, we call the validation function. It is _not_
// called when you assign the value to the flag directly using the = operator.
//
// The validation 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.
//
// This function is safe to call at global construct time (as in the
// example below).

// Now come the command line flag declaration/definition macros that

// for this is initialization: we want people to be able to access
// variables in global constructors and have that not crash, even if
// their global constructor runs before the global constructor here.
// (Obviously, we can't guarantee the flags will have the correct
// default value in that case, but at least accessing them is safe.)
// The only way to do that is have flags point to a static buffer.
// So we make one, using a union to ensure proper alignment, and
// then use placement-new to actually set up the flag with the
// correct default value. 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_<name>, we also
// preemptively define a junk variable, FLAGS_no<name>. 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. 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. We want this so we can put extra
// functionality (like sanity-checking) in DECLARE if we want, and
// make sure it is picked up everywhere.
//
// We also put the type of the variable in the namespace, so that
// people can't DECLARE_int32 something that they DEFINE_bool'd
// elsewhere.

//
// Implement helpful bash-style command line flag completions
//
// ** Functional API:
// HandleCommandLineCompletions() should be called early during
// program startup, but after command line flag code has been
// initialized, such as the beginning of HandleCommandLineHelpFlags().
// It checks the value of the flag --tab_completion_word. 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 \
'/usr/local/bin/gflags_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.

//
// #include "foo.h" // foo.h has a line "DECLARE_int32(start);"
// #include "validators.h" // hypothetical file defining ValidateIsFile()
//
// DEFINE_int32(end, 1000, "The last record to read");
//
// DEFINE_string(filename, "my_file.txt", "The file to read");
// // Crash if the specified file does not exist.
// static bool dummy = RegisterFlagValidator(&FLAGS_filename,
// &ValidateIsFile);
//
// DECLARE_bool(verbose); // some other file has a DEFINE_bool(verbose, ...)
//
// void MyFunc() {
// if (FLAGS_verbose) printf("Records %d-%d\n", FLAGS_start, FLAGS_end);

//
// Then, at the command-line:
// ./foo --noverbose --start=5 --end=100

// --- A note about thread-safety:
//
// We describe many functions in this routine as being thread-hostile,
// thread-compatible, or thread-safe. Here are the meanings we use:
//
// thread-safe: it is safe for multiple threads to call this routine
// (or, when referring to a class, methods of this class)
// concurrently.
// thread-hostile: it is not safe for multiple threads to call this
// routine (or methods of this class) concurrently. In gflags,
// most thread-hostile routines are intended to be called early in,
// or even before, main() -- that is, before threads are spawned.
// thread-compatible: it is safe for multiple threads to read from
// this variable (when applied to variables), or to call const
// methods of this class (when applied to classes), as long as no
// other thread is writing to the variable or calling non-const
// methods of this class.

// To actually define a flag in a file, use DEFINE_bool,

// it useful to register a validator with the flag. This ensures that

// Now come the command line flag declaration/definition macros that

// variables in global constructors and have that not crash, even if
// their global constructor runs before the global constructor here.
// (Obviously, we can't guarantee the flags will have the correct
// default value in that case, but at least accessing them is safe.)
// The only way to do that is have flags point to a static buffer.
// So we make one, using a union to ensure proper alignment, and
// then use placement-new to actually set up the flag with the
// correct default value. 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_<name>, we also
// preemptively define a junk variable, FLAGS_no<name>. 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. 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. We want this so we can put extra
// functionality (like sanity-checking) in DECLARE if we want, and
// make sure it is picked up everywhere.

// people can't DECLARE_int32 something that they DEFINE_bool'd
// elsewhere.

// Implement helpful bash-style command line flag completions
//
// ** Functional API:
// HandleCommandLineCompletions() should be called early during
// program startup, but after command line flag code has been
// initialized, such as the beginning of HandleCommandLineHelpFlags().
// It checks the value of the flag --tab_completion_word. 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 \
'/usr/local/bin/gflags_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.

// This file is needed for windows -- unittests are not part of the
// gflags dll, but still want to include config.h just like the
// dll does, so they can use internal tools and APIs for testing.
//
// The problem is that config.h declares GFLAGS_DLL_DECL to be
// for exporting symbols, but the unittest needs to *import* symbols
// (since it's not the dll).
//
// The solution is to have this file, which is just like config.h but
// sets GFLAGS_DLL_DECL to do a dllimport instead of a dllexport.
//
// The reason we need this extra GFLAGS_DLL_DECL_FOR_UNITTESTS
// variable is in case people want to set GFLAGS_DLL_DECL explicitly
// to something other than __declspec(dllexport). In that case, they
// may want to use something other than __declspec(dllimport) for the
// unittest case. For that, we allow folks to define both
// GFLAGS_DLL_DECL and GFLAGS_DLL_DECL_FOR_UNITTESTS explicitly.

// (or, when referring to a class, methods of this class)
// concurrently.
// thread-hostile: it is not safe for multiple threads to call this
// routine (or methods of this class) concurrently. In gflags,
// most thread-hostile routines are intended to be called early in,
// or even before, main() -- that is, before threads are spawned.
// thread-compatible: it is safe for multiple threads to read from
// this variable (when applied to variables), or to call const
// methods of this class (when applied to classes), as long as no
// other thread is writing to the variable or calling non-const
// methods of this class.

// (Obviously, we can't guarantee the flags will have the correct
// default value in that case, but at least accessing them is safe.)
// The only way to do that is have flags point to a static buffer.
// So we make one, using a union to ensure proper alignment, and
// then use placement-new to actually set up the flag with the
// correct default value. 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_<name>, we also
// preemptively define a junk variable, FLAGS_no<name>. 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. 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. We want this so we can put extra
// functionality (like sanity-checking) in DECLARE if we want, and
// make sure it is picked up everywhere.

// people can't DECLARE_int32 something that they DEFINE_bool'd
// elsewhere.

//
// Implement helpful bash-style command line flag completions
//
// ** Functional API:
// HandleCommandLineCompletions() should be called early during
// program startup, but after command line flag code has been
// initialized, such as the beginning of HandleCommandLineHelpFlags().
// It checks the value of the flag --tab_completion_word. 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.

// This module implements bash-style completions. It achieves this
// goal in the following broad chunks:
//
// 1) Take a to-be-completed word, and examine it for search hints
// 2) Identify all potentially matching flags
// 2a) If there are no matching flags, do nothing.
// 2b) If all matching flags share a common prefix longer than the
// completion word, output just that matching prefix
// 3) Categorize those flags to produce a rough ordering of relevence.
// 4) Potentially trim the set of flags returned to a smaller number
// that bash is happier with
// 5) Output the matching flags in groups ordered by relevence.
// 5a) Force bash to place most-relevent groups at the top of the list
// 5b) Trim most flag's descriptions to fit on a single terminal line

# - The command being used for completion
# - The word being completed
# - The word preceding the completion word.
#
# Here's an example of how you might use this script:
# $ complete -o bashdefault -o default -o nospace -C \
# '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \
# time env binary_name another_binary [...]

// HandleCommandLineHelpFlags(). (Well, actually, ShowUsageWithFlags(),
// ShowUsageWithFlagsRestrict(), and DescribeOneFlag() can be called
// externally too, but there's little need for it.) These are all
// declared in the main gflags.h header file.

// HandleCommandLineHelpFlags() will check what 'reporting' flags have
// been defined, if any -- the "help" part of the function name is a
// bit misleading -- and do the relevant reporting. It should be
// called after all flag-values have been assigned, that is, after

//
// A simple mutex wrapper, supporting locks and read-write locks.
// You should assume the locks are *not* re-entrant.
//
// To use: you should define the following macros in your configure.ac:
// ACX_PTHREAD
// AC_RWLOCK
// The latter is defined in ../autoconf.
//
// This class is meant to be internal-only and should be wrapped by an
// internal namespace. 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.

# Please DO NOT delete this file!

# NOTE: This file lives in /usr/sfw/lib on Solaris 10. Unfortunately,

# according to
# http://forum.java.sun.com/thread.jspa?threadID=5073150
# By passing LDFLAGS='-Lsrc/solaris' to configure, make will pick up

// #include "foo.h" // foo.h has a line "DECLARE_int32(start);"
// #include "validators.h" // hypothetical file defining ValidateIsFile()
//
// DEFINE_int32(end, 1000, "The last record to read");

// // Crash if the specified file does not exist.

//

// concurrently.
// thread-hostile: it is not safe for multiple threads to call this
// routine (or methods of this class) concurrently. In gflags,
// most thread-hostile routines are intended to be called early in,
// or even before, main() -- that is, before threads are spawned.
// thread-compatible: it is safe for multiple threads to read from
// this variable (when applied to variables), or to call const
// methods of this class (when applied to classes), as long as no
// other thread is writing to the variable or calling non-const
// methods of this class.

// To actually define a flag in a file, use DEFINE_bool,
// DEFINE_string, etc. at the bottom of this file. You may also find
// it useful to register a validator with the flag. This ensures that

// called when you assign the value to the flag directly using the = operator.
//
// The validation 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

//

// their global constructor runs before the global constructor here.
// (Obviously, we can't guarantee the flags will have the correct
// default value in that case, but at least accessing them is safe.)
// The only way to do that is have flags point to a static buffer.
// So we make one, using a union to ensure proper alignment, and
// then use placement-new to actually set up the flag with the
// correct default value. 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_<name>, we also
// preemptively define a junk variable, FLAGS_no<name>. 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. 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. We want this so we can put extra
// functionality (like sanity-checking) in DECLARE if we want, and
// make sure it is picked up everywhere.

// people can't DECLARE_int32 something that they DEFINE_bool'd
// elsewhere.

//
// Implement helpful bash-style command line flag completions
//
// ** Functional API:
// HandleCommandLineCompletions() should be called early during
// program startup, but after command line flag code has been
// initialized, such as the beginning of HandleCommandLineHelpFlags().
// It checks the value of the flag --tab_completion_word. 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.

Overview
--------
HappyHTTP is a simple C++ library for issuing HTTP requests and
processing responses.
- Simple to integrate - just drop in the [.h](happyhttp.h) and
[.cpp](happyhttp.cpp) files
- Easy-to-use interface ([example](#example))
- Non-blocking operation, suitable for use in game update loops
- Supports pipelining. You can issue multiple requests without waiting
for responses.
- Licensed under the [zlib/libpng
license](http://www.opensource.org/licenses/zlib-license.php).
- Cross-platform (Linux, OSX, Windows)
* * * * *
Download
--------
Latest Version is 0.1:
[happyhttp-0.1.tar.gz](http://www.scumways.com/happyhttp/happyhttp-0.1.tar.gz)
* * * * *
Usage
-----
The interface is based loosely on Python's
[httplib](http://docs.python.org/lib/module-httplib.html).
All HappyHTTP code is kept within the `happyhttp::` namespace
To issue and process a HTTP request, the basic steps are:
1. Create a connection object
2. Set up callbacks for handling responses
3. Issue request(s)
4. 'pump' the connection at regular intervals. As responses are
received, the callbacks will be invoked.
### Connection object methods
**`Connection( const char* host, int port )`**
Constructor. Specifies host and port, but connection isn't made until
request is issued or connect() is called.
**`~Connection()`**
Destructor. If connection is open, it'll be closed, and any outstanding
requests will be discarded.
**`void setcallbacks( ResponseBegin_CB begincb, ResponseData_CB datacb, ResponseComplete_CB completecb, void* userdata )`**
Set up the response handling callbacks. These will be invoked during
calls to pump().
`begincb` - called when the responses headers have been received\
`datacb` - called repeatedly to handle body data
`completecb` - response is completed
`userdata` - passed as a param to all callbacks.
**`void connect()`**
Don't need to call connect() explicitly as issuing a request will call
it automatically if needed. But it could block (for name lookup etc), so
you might prefer to call it in advance.
**`void close()`**
// close connection, discarding any pending requests.
**`void pump()`**
Update the connection (non-blocking) Just keep calling this regularly
to service outstanding requests. As responses are received, the
callbacks will be invoked.
**`bool outstanding() const`**
Returns true if any requests are still outstanding.
**`void request( const char* method, const char* url, const char* headers[], const unsigned char* body, int bodysize )`**
High-level request interface. Issues a request.
`method` - "GET", "POST" etc...
`url` - eg "/index.html"
`headers` - array of name/value pairs, terminated by a null-ptr
`body, bodysize` - specify body data of request (eg values for a form)
**`void putrequest( const char* method, const char* url )`**
(part of low-level request interface)
Begin a request
method is "GET", "POST" etc...
url is only path part: eg "/index.html"
**`void putheader( const char* header, const char* value )`**
**`void putheader( const char* header, int numericvalue )`**
(part of low-level request interface)
Add a header to the request (call after putrequest() )
**`void endheaders()`**
(part of low-level request interface)
Indicate that your are finished adding headers and the request can be
issued.
`void send( const unsigned char* buf, int numbytes )`
(part of low-level request interface)
send body data if any. To be called after endheaders()
### Callback types
**`typedef void (*ResponseBegin_CB)( const Response* r, void* userdata )`**
Invoked when all the headers for a response have been received.\
The Response object can be queried to determine status and header
values.
`userdata` is the same value that was passed in to
`Connection::setcallbacks()`.
**`typedef void (*ResponseData_CB)( const Response* r, void* userdata, const unsigned char* data, int numbytes )`**
This callback is invoked to pass out data from the body of the
response. It may be called multiple times, or not at all (if there is no
body).
**`typedef void (*ResponseComplete_CB)( const Response* r, void* userdata )`**
Once a response is completed, this callback is invoked. When the
callback returns, the respsonse object will be destroyed.
### Response object methods
When a callback is invoked, a response object is passed to it. The
following member functions can be used to query the response:
**`const char* getheader( const char* name ) const`**
retrieve the value of a header (returns 0 if not present)
**`int getstatus() const`**
Get the HTTP status code returned by the server
**`const char* getreason() const`**
Get the HTTP response reason string returned by the server
### Error Handling
If an error occurs, a `Wobbly` is thrown. The `Wobbly::what()` method
returns a text description.
* * * * *
Example
-------
For more examples, see [test.cpp](test.cpp).
static int count=0;
// invoked when response headers have been received
void OnBegin( const happyhttp::Response* r, void* userdata )
{
printf( "BEGIN (%d %s)\n", r-&gtgetstatus(), r-&gtgetreason() );
count = 0;
}
// invoked to process response body data (may be called multiple times)
void OnData( const happyhttp::Response* r, void* userdata, const unsigned char* data, int n )
{
fwrite( data,1,n, stdout );
count += n;
}
// invoked when response is complete
void OnComplete( const happyhttp::Response* r, void* userdata )
{
printf( "COMPLETE (%d bytes)\n", count );
}
void TestGET()
{
happyhttp::Connection conn( "www.scumways.com", 80 );
conn.setcallbacks( OnBegin, OnData, OnComplete, 0 );
conn.request( "GET", "/happyhttp/test.php" );
while( conn.outstanding() )
conn.pump();
}
* * * * *
TODO
----
- Proxy support
- Add helper functions for URL wrangling
- Improve error text (and maybe some more exception types?)
- HTTP 0.9 support
- Improved documentation and examples

Changes in 1.4.13-stable:
o If the kernel tells us that there are a negative number of bytes to read from a socket, do not believe it. Fixes bug 2841177; found by Alexander Pronchenkov.
o Do not allocate the maximum event queue and fd array for the epoll backend at startup. Instead, start out accepting 32 events at a time, and double the queue's size when it seems that the OS is generating events faster than we're requesting them. Saves up to 512K per epoll-based event_base. Resolves bug 2839240.
o Fix compilation on Android, which forgot to define fd_mask in its sys/select.h
o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec
o Rename our replacement compat/sys/_time.h header to avoid build a conflict on HPUX; reported by Kathryn Hogg.
o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian.
o Fix a problem with excessive memory allocation when using multiple event priorities.
o When running set[ug]id, don't check the environment. Based on a patch from OpenBSD.
Changes in 1.4.12-stable:
o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair.
o Fix an obscure timing-dependent, allocator-dependent crash in the evdns code.
o Use __VA_ARGS__ syntax for varargs macros in event_rpcgen when compiler is not GCC.
o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32).
o Fix another pair of fencepost bugs in epoll.c. [Patch from Adam Langley.]
o Do not break evdns connections to nameservers when our IP changes.
o Set truncated flag correctly in evdns server replies.
o Disable strict aliasing with GCC: our code is not compliant with it.
Changes in 1.4.11-stable:
o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen]
o Remove the limit on size of HTTP headers by removing static buffers.
o Fix a nasty dangling pointer bug in epoll.c that could occur after epoll_recalc(). [Patch from Kevin Springborn]
o Distribute Win32-Code/event-config.h, not ./event-config.h
Changes in 1.4.10-stable:
o clean up buffered http connection data on reset; reported by Brian O'Kelley
o bug fix and potential race condition in signal handling; from Alexander Drozdov
o rename the Solaris event ports backend to evport
o support compilation on Haiku
o fix signal processing when a signal callback delivers a signal; from Alexander Drozdov
o const-ify some arguments to evdns functions.
o off-by-one error in epoll_recalc; reported by Victor Goya
o include Doxyfile in tar ball; from Jeff Garzik

o Fix a merge problem in which name_from_addr returned pointers to the stack; found by Jiang Hong.
o Do not remove Accept-Encoding header
Changes in 1.4.7-stable:
o Fix a bug where headers arriving in multiple packets were not parsed; fix from Jiang Hong; test by me.
Changes in 1.4.6-stable:
o evutil.h now includes <stdarg.h> directly
o switch all uses of [v]snprintf over to evutil
o Correct handling of trailing headers in chunked replies; from Scott Lamb.
o Support multi-line HTTP headers; based on a patch from Moshe Litvin
o Reject negative Content-Length headers; anonymous bug report
o Detect CLOCK_MONOTONIC at runtime for evdns; anonymous bug report
o Fix a bug where deleting signals with the kqueue backend would cause subsequent adds to fail
o Support multiple events listening on the same signal; make signals regular events that go on the same event queue; problem report by Alexander Drozdov.
o Deal with evbuffer_read() returning -1 on EINTR|EAGAIN; from Adam Langley.
o Fix a bug in which the DNS server would incorrectly set the type of a cname reply to a.
o Fix a bug where setting the timeout on a bufferevent would take not effect if the event was already pending.
o Fix a memory leak when using signals for some event bases; reported by Alexander Drozdov.
o Add libevent.vcproj file to distribution to help with Windows build.
o Fix a problem with epoll() and reinit; problem report by Alexander Drozdov.

o Do not warn on accept when errno is either EAGAIN or EINTR
Changes in 1.4.5-stable:
o Fix connection keep-alive behavior for HTTP/1.0
o Fix use of freed memory in event_reinit; pointed out by Peter Postma
o Constify struct timeval * where possible; pointed out by Forest Wilkinson
o allow min_heap_erase to be called on removed members; from liusifan.
o Rename INPUT and OUTPUT to EVRPC_INPUT and EVRPC_OUTPUT. Retain INPUT/OUTPUT aliases on on-win32 platforms for backwards compatibility.
o Do not use SO_REUSEADDR when connecting
o Fix Windows build
o Fix a bug in event_rpcgen when generated fixed-sized entries
Changes in 1.4.4-stable:
o Correct the documentation on buffer printf functions.
o Don't warn on unimplemented epoll_create(): this isn't a problem, just a reason to fall back to poll or select.
o Correctly handle timeouts larger than 35 minutes on Linux with epoll.c. This is probably a kernel defect, but we'll have to support old kernels anyway even if it gets fixed.
o Fix a potential stack corruption bug in tagging on 64-bit CPUs.
o expose bufferevent_setwatermark via header files and fix high watermark on read
o fix a bug in bufferevent read water marks and add a test for them
o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents
o use libevent's internal timercmp on all platforms, to avoid bugs on old platforms where timercmp(a,b,<=) is buggy.
o reduce system calls for getting current time by caching it.
o fix evhttp_bind_socket() so that multiple sockets can be bound by the same http server.
o Build test directory correctly with CPPFLAGS set.
o Fix build under Visual C++ 2005.
o Expose evhttp_accept_socket() API.

o Patch from Tani Hosokawa: make some functions in http.c threadsafe.
o Do not free the kqop file descriptor in other processes, also allow it to be 0; from Andrei Nigmatulin
o make event_rpcgen.py generate code include event-config.h; reported by Sam Banks.
o make event methods static so that they are not exported; from Andrei Nigmatulin
o make RPC replies use application/octet-stream as mime type
o do not delete uninitialized timeout event in evdns
Changes in 1.4.2-rc:
o remove pending timeouts on event_base_free()
o also check EAGAIN for Solaris' event ports; from W.C.A. Wijngaards
o devpoll and evport need reinit; tested by W.C.A Wijngaards
o event_base_get_method; from Springande Ulv
o Send CRLF after each chunk in HTTP output, for compliance with RFC2626. Patch from "propanbutan". Fixes bug 1894184.
o Add a int64_t parsing function, with unit tests, so we can apply Scott Lamb's fix to allow large HTTP values.
o Use a 64-bit field to hold HTTP content-lengths. Patch from Scott Lamb.
o Allow regression code to build even without Python installed
o remove NDEBUG ifdefs from evdns.c
o update documentation of event_loop and event_base_loop; from Tani Hosokawa.
o detect integer types properly on platforms without stdint.h
o Remove "AM_MAINTAINER_MODE" declaration in configure.in: now makefiles and configure should get re-generated automatically when Makefile.am or configure.in chanes.
o do not insert event into list when evsel->add fails
Changes in 1.4.1-beta:
o free minheap on event_base_free(); from Christopher Layne
o debug cleanups in signal.c; from Christopher Layne
o provide event_base_new() that does not set the current_base global
o bufferevent_write now uses a const source argument; report from Charles Kerr
o better documentation for event_base_loopexit; from Scott Lamb.
o Make kqueue have the same behavior as other backends when a signal is caught between event_add() and event_loop(). Previously, it would catch and ignore such signals.
o Make kqueue restore signal handlers correctly when event_del() is called.
o provide event_reinit() to reintialize an event_base after fork
o small improvements to evhttp documentation
o always generate Date and Content-Length headers for HTTP/1.1 replies
o set the correct event base for HTTP close events
o New function, event_{base_}loopbreak. Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb
o Removed obsoleted recalc code
o pull setters/getters out of RPC structures into a base class to which we just need to store a pointer; this reduces the memory footprint of these structures.
o fix a bug with event_rpcgen for integers
o move EV_PERSIST handling out of the event backends
o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly.
o prefix {encode,decode}_tag functions with evtag to avoid collisions
o Correctly handle DNS replies with no answers set (Fixes bug 1846282)
o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings. (Nick has been building with these for a while, but they might be useful to other developers.)
o When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions.
o removed linger from http server socket; reported by Ilya Martynov
o allow \r or \n individually to separate HTTP headers instead of the standard "\r\n"; from Charles Kerr.
o demote most http warnings to debug messages
o Fix Solaris compilation; from Magne Mahre
o Add a "Date" header to HTTP responses, as required by HTTP 1.1.
o Support specifying the local address of an evhttp_connection using set_local_address
o Fix a memory leak in which failed HTTP connections would not free the request object
o Make adding of array members in event_rpcgen more efficient, but doubling memory allocation
o Fix a memory leak in the DNS server
o Fix compilation when DNS_USE_OPENSSL_FOR_ID is enabled
o Fix buffer size and string generation in evdns_resolve_reverse_ipv6().
o Respond to nonstandard DNS queries with "NOTIMPL" rather than by ignoring them.
o In DNS responses, the CD flag should be preserved, not the TC flag.
o Fix http.c to compile properly with USE_DEBUG; from Christopher Layne
o Handle NULL timeouts correctly on Solaris; from Trond Norbye
o Recalculate pending events properly when reallocating event array on Solaris; from Trond Norbye
o Add Doxygen documentation to header files; from Mark Heily
o Add a evdns_set_transaction_id_fn() function to override the default
transaction ID generation code.
o Add an evutil module (with header evutil.h) to implement our standard cross-platform hacks, on the theory that somebody else would like to use them too.
o Fix signals implementation on windows.
o Fix http module on windows to close sockets properly.
o Make autogen.sh script run correctly on systems where /bin/sh isn't bash. (Patch from Trond Norbye, rewritten by Hagne Mahre and then Hannah Schroeter.)
o Skip calling gettime() in timeout_process if we are not in fact waiting for any events. (Patch from Trond Norbye)
o Make test subdirectory compile under mingw.
o Fix win32 buffer.c behavior so that it is correct for sockets (which do not like ReadFile and WriteFile).
o Make the test.sh script run unit tests for the evpoll method.
o Make the entire evdns.h header enclosed in "extern C" as appropriate.
o Fix implementation of strsep on platforms that lack it
o Fix implementation of getaddrinfo on platforms that lack it; mainly, this will make Windows http.c work better. Original patch by Lubomir Marinov.
o Fix evport implementation: port_disassociate called on unassociated events resulting in bogus errors; more efficient memory management; from Trond Norbye and Prakash Sangappa
o support for hooks on rpc input and output; can be used to implement rpc independent processing such as compression or authentication.
o use a min heap instead of a red-black tree for timeouts; as a result finding the min is a O(1) operation now; from Maxim Yegorushkin
o associate an event base with an rpc pool
o added two additional libraries: libevent_core and libevent_extra in addition to the regular libevent. libevent_core contains only the event core whereas libevent_extra contains dns, http and rpc support
o Begin using libtool's library versioning support correctly. If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility.
o Fix evhttp.h compilation when TAILQ_ENTRY is not defined.
o Small code cleanups in epoll_dispatch().
o Increase the maximum number of addresses read from a packet in evdns to 32.
o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in.
o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated.
o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests.
o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes.
o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files.
o Remove the long-deprecated acconfig.h file.
o Do not require #include <sys/types.h> before #include <event.h>.
o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions.
o Fix many build issues when using the Microsoft C compiler.
o Remove a bash-ism in autogen.sh
o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL. Patch from Christopher Layne.
o Make the logic for active events work better with internal events; patch from Christopher Layne.
o We do not need to specially remove a timeout before calling event_del; patch from Christopher Layne.

# This is the point release for libevent. It shouldn't include any
# a/b/c/d/e notations.
RELEASE = 1.4
# This is the version info for the libevent binary API. It has three
# numbers:
# Current -- the number of the binary API that we're implementing
# Revision -- which iteration of the implementation of the binary
# API are we supplying?
# Age -- How many previous binary API versions do we also
# support?
#
# If we release a new version that does not change the binary API,
# increment Revision.
#
# If we release a new version that changes the binary API, but does
# not break programs compiled against the old binary API, increment
# Current and Age. Set Revision to 0, since this is the first
# implementation of the new API.
#
# Otherwise, we're changing the binary API and breaking bakward
# compatibility with old binaries. Increment Current. Set Age to 0,
# since we're backward compatible with no previous APIs. Set Revision
# to 0 too.
# History:
# Libevent 1.4.1 was 2:0:0
# Libevent 1.4.2 should be 3:0:0
# Libevent 1.4.5 is 3:0:1 (we forgot to increment in the past)

# This is the version info for the libevent binary API. It has three
# numbers:
# Current -- the number of the binary API that we're implementing
# Revision -- which iteration of the implementation of the binary
# API are we supplying?
# Age -- How many previous binary API versions do we also
# support?
#
# If we release a new version that does not change the binary API,
# increment Revision.
#
# If we release a new version that changes the binary API, but does
# not break programs compiled against the old binary API, increment
# Current and Age. Set Revision to 0, since this is the first
# implementation of the new API.
#
# Otherwise, we're changing the binary API and breaking bakward
# compatibility with old binaries. Increment Current. Set Age to 0,
# since we're backward compatible with no previous APIs. Set Revision
# to 0 too.
# History:
# Libevent 1.4.1 was 2:0:0
# Libevent 1.4.2 should be 3:0:0
# Libevent 1.4.5 is 3:0:1 (we forgot to increment in the past)

To build libevent, type
$ ./configure && make
(If you got libevent from the subversion repository, you will
first need to run the included "autogen.sh" script in order to
generate the configure script.)
Install as root via
# make install
You can run the regression tests by
$ make verify
Before, reporting any problems, please run the regression tests.
To enable the low-level tracing build the library as:
CFLAGS=-DUSE_DEBUG ./configure [...]

Name: libevent
URL: http://www.monkey.org/~provos/libevent/
Version: 1.4.13
License: BSD
Security Critical: yes
Local Modifications:
Rather than use libevent's own build system, we just build a Chrome
static library using GYP.
1) Run configure and "make event-config.h" on Linux, FreeBSD, Solaris,
and Mac and copy config.h and event-config.h to linux/, freebsd/,
solaris/, and mac/ respectively.
2) Add libevent.gyp.
3) chromium.patch is applied to allow libevent to be used without
being installed.
4) The directories WIN32-Code and WIN32-Prj are not included.
5) Apply r87338.
6) The configs for android were copied from Linux's which were very close to
android one with the exception of HAVE_FD_MASK and HAVE_STRLCPY.

/*
* This file defines five types of data structures: singly-linked lists,
* lists, simple queues, tail queues, and circular queues.
*
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A simple queue is headed by a pair of pointers, one the head of the
* list and the other to the tail of the list. The elements are singly
* linked to save space, so elements can only be removed from the
* head of the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the
* list. A simple queue may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.
