For example, we don't support +// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and +// repetition count ("x{5,7}"), among others. +// +// Below is the syntax that we do support. We chose it to be a +// subset of both PCRE and POSIX extended regex, so it's easy to +// learn wherever you come from. In the following: 'A' denotes a +// literal character, period (.), or a single \\ escape sequence; +// 'x' and 'y' denote regular expressions; 'm' and 'n' are for +// natural numbers. +// +// c matches any literal character c +// \\d matches any decimal digit +// \\D matches any character that's not a decimal digit +// \\f matches \f +// \\n matches \n +// \\r matches \r +// \\s matches any ASCII whitespace, including \n +// \\S matches any character that's not a whitespace +// \\t matches \t +// \\v matches \v +// \\w matches any letter, _, or decimal digit +// \\W matches any character that \\w doesn't match +// \\c matches any literal character c, which must be a punctuation +// . matches any single character except \n +// A? matches 0 or 1 occurrences of A +// A* matches 0 or many occurrences of A +// A+ matches 1 or many occurrences of A +// ^ matches the beginning of a string (not that of each line) +// $ matches the end of a string (not that of each line) +// xy matches x followed by y +// +// If you accidentally use PCRE or POSIX extended regex features +// not implemented by us, you will get a run-time failure. In that +// case, please try to rewrite your regular expression within the +// above syntax. +// +// This implementation is *not* meant to be as highly tuned or robust +// as a compiled regex library, but should perform well enough for a +// death test, which already incurs significant overhead by launching +// a child process. +// +// Known caveats: +// +// A "threadsafe" style death test obtains the path to the test +// program from argv[0] and re-executes it in the sub-process. For +// simplicity, the current implementation doesn't search the PATH +// when launching the sub-process. This means that the user must +// invoke the test program via a path that contains at least one +// path separator (e.g. path/to/foo_test and +// /absolute/path/to/bar_test are fine, but foo_test is not).

Macros in -// this section tell Google Test what kind of environment it is being -// used in, such that Google Test can provide environment-specific -// features and implementations. -// -// Google Test tries to automatically detect the properties of its -// environment, so users usually don't need to worry about these -// macros. However, the automatic detection is not perfect. -// Sometimes it's necessary for a user to define some of the following -// macros in the build script to override Google Test's decisions. -// -// If the user doesn't define a macro in the list, Google Test will -// provide a default definition. After this header is #included, all -// macros in this list will be defined to either 1 or 0. -// -// Notes to maintainers: -// - Each macro here is a user-tweakable knob; do not grow the list -// lightly. -// - Use #if to key off these macros. Don't use #ifdef or "#if -// defined(...)", which will not work as these macros are ALWAYS -// defined. -// -// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2) -// is/isn't available. -// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions -// are enabled. -// GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular -// expressions are/aren't available. -// GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that -// is/isn't available. -// GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't -// enabled. -// GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that -// std::wstring does/doesn't work (Google Test can -// be used where std::wstring is unavailable). -// GTEST_HAS_SEH - Define it to 1/0 to indicate whether the -// compiler supports Microsoft's "Structured -// Exception Handling". -// GTEST_HAS_STREAM_REDIRECTION -// - Define it to 1/0 to indicate whether the -// platform supports I/O stream redirection using -// dup() and dup2(). -// GTEST_LINKED_AS_SHARED_LIBRARY -// - Define to 1 when compiling tests that use -// Google Test as a shared library (known as -// DLL on Windows). -// GTEST_CREATE_SHARED_LIBRARY -// - Define to 1 when compiling Google Test itself -// as a shared library. -// GTEST_DEFAULT_DEATH_TEST_STYLE -// - The default value of --gtest_death_test_style. -// The legacy default has been "fast" in the open -// source version since 2008. The recommended value -// is "threadsafe", and can be set in -// custom/gtest-port.h. - -// Platform-indicating macros -// -------------------------- -// -// Macros indicating the platform on which Google Test is being used -// (a macro is defined to 1 if compiled on the given platform; -// otherwise UNDEFINED -- it's never defined to 0.).

If you notice any problems on your platform, please notify -// googletestframework@googlegroups.com (patches for fixing them are -// even more welcome!). -// -// It is possible that none of the GTEST_OS_* macros are defined. - -// Feature-indicating macros -// ------------------------- -// -// Macros indicating which Google Test features are available (a macro -// is defined to 1 if the corresponding feature is supported; -// otherwise UNDEFINED -- it's never defined to 0.). Google Test -// defines these macros automatically. Code outside Google Test MUST -// NOT define them. -// -// These macros are public so that portable tests can be written. -// Such tests typically surround code using a feature with an #if -// which controls that code. For example: -// -// #if GTEST_HAS_DEATH_TEST -// EXPECT_DEATH(DoSomethingDeadly()); -// #endif -// -// GTEST_HAS_DEATH_TEST - death tests -// GTEST_HAS_TYPED_TEST - typed tests -// GTEST_HAS_TYPED_TEST_P - type-parameterized tests -// GTEST_IS_THREADSAFE - Google Test is thread-safe. -// GOOGLETEST_CM0007 DO NOT DELETE -// GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with -// GTEST_HAS_POSIX_RE (see above) which users can -// define themselves. -// GTEST_USES_SIMPLE_RE - our own simple regex is used; -// the above RE\b(s) are mutually exclusive. - -// Misc public macros -// ------------------ -// -// GTEST_FLAG(flag_name) - references the variable corresponding to -// the given Google Test flag. - -// Internal utilities -// ------------------ -// -// The following macros and utilities are for Google Test's INTERNAL -// use only. Code outside Google Test MUST NOT USE THEM DIRECTLY. -// -// Macros for basic C++ coding: -// GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning. -// GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a -// variable don't have to be used. -// GTEST_DISALLOW_ASSIGN_ - disables operator=. -// GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=. -// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used. -// GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is -// suppressed (constant conditional). -// GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127 -// is suppressed. -// -// Synchronization: -// Mutex, MutexLock, ThreadLocal, GetThreadCount() -// - synchronization primitives. -// -// Template meta programming: -// IteratorTraits - partial implementation of std::iterator_traits, which -// is not available in libCstd when compiled with Sun C++. -// -// -// Regular expressions: -// RE - a simple regular expression class using the POSIX -// Extended Regular Expression syntax on UNIX-like platforms -// GOOGLETEST_CM0008 DO NOT DELETE -// or a reduced regular exception syntax on other -// platforms, including Windows. -// Logging: -// GTEST_LOG_() - logs messages at the specified severity level. -// LogToStderr() - directs all log messages to stderr. -// FlushInfoLog() - flushes informational log messages. -// -// Stdout and stderr capturing: -// CaptureStdout() - starts capturing stdout. -// GetCapturedStdout() - stops capturing stdout and returns the captured -// string. -// CaptureStderr() - starts capturing stderr. -// GetCapturedStderr() - stops capturing stderr and returns the captured -// string. -// -// Integer types: -// TypeWithSize - maps an integer to a int type. -// Int32, UInt32, Int64, UInt64, TimeInMillis -// - integers of known sizes. -// BiggestInt - the biggest signed integer type. -// -// Command-line utilities: -// GTEST_DECLARE_*() - declares a flag. -// GTEST_DEFINE_*() - defines a flag. -// GetInjectableArgvs() - returns the command line as a vector of strings. -// -// Environment variable utilities: -// GetEnv() - gets the value of an environment variable. -// BoolFromGTestEnv() - parses a bool environment variable. -// Int32FromGTestEnv() - parses an Int32 environment variable. -// StringFromGTestEnv() - parses a string environment variable. -// -// Deprecation warnings: -// GTEST_INTERNAL_DEPRECATED(message) - attribute marking a function as -// deprecated; calling a marked function -// should generate a compiler warning - -#include // for isspace, etc -#include // for ptrdiff_t -#include -#include -#include -#include -#include - -#ifndef _WIN32_WCE -# include -# include -#endif // !_WIN32_WCE - -#if defined __APPLE__ -# include -# include -#endif - -#include // NOLINT -#include // NOLINT -#include // NOLINT -#include // NOLINT -#include -#include -#include // NOLINT - -// Copyright 2015, 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.

This limited -// implementation should be enough most of the time when writing -// death tests; though it lacks many features you can find in PCRE -// or POSIX extended regex syntax. For example, we don't support -// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and -// repetition count ("x{5,7}"), among others. -// -// Below is the syntax that we do support. We chose it to be a -// subset of both PCRE and POSIX extended regex, so it's easy to -// learn wherever you come from. In the following: 'A' denotes a -// literal character, period (.), or a single \\ escape sequence; -// 'x' and 'y' denote regular expressions; 'm' and 'n' are for -// natural numbers. -// -// c matches any literal character c -// \\d matches any decimal digit -// \\D matches any character that's not a decimal digit -// \\f matches \f -// \\n matches \n -// \\r matches \r -// \\s matches any ASCII whitespace, including \n -// \\S matches any character that's not a whitespace -// \\t matches \t -// \\v matches \v -// \\w matches any letter, _, or decimal digit -// \\W matches any character that \\w doesn't match -// \\c matches any literal character c, which must be a punctuation -// . matches any single character except \n -// A? matches 0 or 1 occurrences of A -// A* matches 0 or many occurrences of A -// A+ matches 1 or many occurrences of A -// ^ matches the beginning of a string (not that of each line) -// $ matches the end of a string (not that of each line) -// xy matches x followed by y -// -// If you accidentally use PCRE or POSIX extended regex features -// not implemented by us, you will get a run-time failure. In that -// case, please try to rewrite your regular expression within the -// above syntax. -// -// This implementation is *not* meant to be as highly tuned or robust -// as a compiled regex library, but should perform well enough for a -// death test, which already incurs significant overhead by launching -// a child process. -// -// Known caveats: -// -// A "threadsafe" style death test obtains the path to the test -// program from argv[0] and re-executes it in the sub-process. For -// simplicity, the current implementation doesn't search the PATH -// when launching the sub-process. This means that the user must -// invoke the test program via a path that contains at least one -// path separator (e.g. path/to/foo_test and -// /absolute/path/to/bar_test are fine, but foo_test is not).
