# How to contribute #
We'd love to accept your patches and contributions to this project. There are
a just a few small guidelines you need to follow.
## Contributor License Agreement ##
Contributions to any Google project must be accompanied by a Contributor
License Agreement. This is not a copyright **assignment**, it simply gives
Google permission to use and redistribute your contributions as part of the
project.
* If you are an individual writing original source code and you're sure you
own the intellectual property, then you'll need to sign an [individual
CLA][].
* If you work for a company that wants to allow you to contribute your work,
then you'll need to sign a [corporate CLA][].
You generally only need to submit a CLA once, so if you've already submitted
one (even if it was for a different project), you probably don't need to do it
again.
[individual CLA]: https://developers.google.com/open-source/cla/individual
[corporate CLA]: https://developers.google.com/open-source/cla/corporate
Once your CLA is submitted (or if you already submitted one for
another Google project), make a commit adding yourself to the
[AUTHORS][] and [CONTRIBUTORS][] files. This commit can be part
of your first [pull request][].
[AUTHORS]: AUTHORS
[CONTRIBUTORS]: CONTRIBUTORS
## Submitting a patch ##
1. It's generally best to start by opening a new issue describing the bug or
feature you're intending to fix. Even if you think it's relatively minor,
it's helpful to know what people are working on. Mention in the initial
issue that you are planning to work on that bug or feature so that it can
be assigned to you.
1. Follow the normal process of [forking][] the project, and setup a new
branch to work in. It's important that each group of changes be done in
separate branches in order to ensure that a pull request only includes the
commits related to that bug or feature.
1. Do your best to have [well-formed commit messages][] for each change.
This provides consistency throughout the project, and ensures that commit
messages are able to be formatted properly by various git tools.
1. Finally, push the commits to your fork and submit a [pull request][].

Glog-Specific Install Notes
================================
*** NOTE FOR 64-BIT LINUX SYSTEMS
The glibc built-in stack-unwinder on 64-bit systems has some problems
with the glog libraries. (In particular, if you are using
InstallFailureSignalHandler(), the signal may be raised in the middle
of malloc, holding some malloc-related locks when they invoke the
stack unwinder. The built-in stack unwinder may call malloc
recursively, which may require the thread to acquire a lock it already
holds: deadlock.)
For that reason, if you use a 64-bit system and you need
InstallFailureSignalHandler(), we strongly recommend you install
libunwind before trying to configure or install google glog.
libunwind can be found at
http://download.savannah.nongnu.org/releases/libunwind/libunwind-snap-070410.tar.gz
Even if you already have libunwind installed, you will probably still
need to install from the snapshot to get the latest version.
CAUTION: if you install libunwind from the URL above, be aware that
you may have trouble if you try to statically link your binary with
glog: that is, if you link with 'gcc -static -lgcc_eh ...'. This
is because both libunwind and libgcc implement the same C++ exception
handling APIs, but they implement them differently on some platforms.
This is not likely to be a problem on ia64, but may be on x86-64.
Also, if you link binaries statically, make sure that you add
-Wl,--eh-frame-hdr to your linker options. This is required so that
libunwind can find the information generated by the compiler required
for stack unwinding.
Using -static is rare, though, so unless you know this will affect you
it probably won't.
If you cannot or do not wish to install libunwind, you can still try
to use two kinds of stack-unwinder: 1. glibc built-in stack-unwinder
and 2. frame pointer based stack-unwinder.
1. As we already mentioned, glibc's unwinder has a deadlock issue.
However, if you don't use InstallFailureSignalHandler() or you don't
worry about the rare possibilities of deadlocks, you can use this
stack-unwinder. If you specify no options and libunwind isn't
detected on your system, the configure script chooses this unwinder by
default.
2. The frame pointer based stack unwinder requires that your
application, the glog library, and system libraries like libc, all be
compiled with a frame pointer. This is *not* the default for x86-64.
If you are on x86-64 system, know that you have a set of system
libraries with frame-pointers enabled, and compile all your
applications with -fno-omit-frame-pointer, then you can enable the
frame pointer based stack unwinder by passing the
--enable-frame-pointers flag to configure.
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.md' 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.md' 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.
Building glog - Using vcpkg
===========================
The url of vcpkg is: https://github.com/Microsoft/vcpkg
You can download and install glog using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh

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.md' 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.

This project has been ported to Windows, including stack tracing, signal
handling, and unit tests.
A Visual Studio solution file is explicitly not provided because it is not
maintainable. Instead, a CMake build system exists to generate the correct
solution for your version of Visual Studio.
In short,
(1) Install CMake from: https://cmake.org/download/
(2) With CMake on your PATH, run `cmake .` to generate the build files
(3) Either use `cmake --build`, or open the generated solution
CMake provides different generators, and by default will pick the most relevant
one to your environment. If you need a specific version of Visual Studio, use
`cmake . -G <generator-name>`, and see `cmake --help` for the available
generators. Also see `-T <toolset-name>`, which can used to request the native
x64 toolchain with `-T host=x64`.

# Glog - CMake Support
Glog comes with a CMake build script ([CMakeLists.txt](../CMakeLists.txt)) that can be used on a wide range of platforms.
If you don't have CMake installed already, you can download it for free from <http://www.cmake.org/>.
CMake works by generating native makefiles or build projects that can be used in the compiler environment of your choice.
You can either build Glog with CMake as a standalone project or it can be incorporated into an existing CMake build for another project.
## Table of Contents
- [Building Glog with CMake](#building-glog-with-cmake)
- [Consuming Glog in a CMake Project](#consuming-glog-in-a-cmake-project)
- [Incorporating Glog into a CMake Project](#incorporating-glog-into-a-cmake-project)
## Building Glog with CMake
When building Glog as a standalone project, on Unix-like systems with GNU Make as build tool, the typical workflow is:
1. Get the source code and change to it.
e.g. cloning with git:
```bash
git clone git@github.com:google/glog.git
cd glog
```
2. Run CMake to configure the build tree.
```bash
cmake -H. -Bbuild -G "Unix Makefiles"
```
note: To get the list of available generators (e.g. Visual Studio), use `-G ""`
3. Afterwards, generated files can be used to compile the project.
```bash
cmake --build build
```
4. Test the build software (optional).
```bash
cmake --build build --target test
```
5. Install the built files (optional).
```bash
cmake --build build --target install
```
## Consuming Glog in a CMake Project
If you have Glog installed in your system, you can use the CMake command
`find_package()` to include it in your CMake Project.
```cmake
cmake_minimum_required(VERSION 3.0.2)
project(myproj VERSION 1.0)
find_package(glog 0.4.0 REQUIRED)
add_executable(myapp main.cpp)
target_link_libraries(myapp glog::glog)
```
Compile definitions and options will be added automatically to your target as
needed.
## Incorporating Glog into a CMake Project
You can also use the CMake command `add_subdirectory()` to include Glog directly from a subdirectory of your project.
The **glog::glog** target is in this case an ALIAS library target for the **glog** library target.
```cmake
cmake_minimum_required(VERSION 3.0.2)
project(myproj VERSION 1.0)
add_subdirectory(glog)
add_executable(myapp main.cpp)
target_link_libraries(myapp glog::glog)
```
Again, compile definitions and options will be added automatically to your target as
needed.

<h1>How To Use Google Logging Library (glog)</h1>
<small>(as of
<script type=text/javascript>
var lm = new Date(document.lastModified);
document.write(lm.toDateString());
</script>)
</small>
<br>
<h2> <A NAME=intro>Introduction</A> </h2>
<p><b>Google glog</b> is a library that implements application-level
logging. This library provides logging APIs based on C++-style
streams and various helper macros.
You can log a message by simply streaming things to LOG(&lt;a
particular <a href="#severity">severity level</a>&gt;), e.g.
<pre>
#include &lt;glog/logging.h&gt;
int main(int argc, char* argv[]) {
// Initialize Google's logging library.
google::InitGoogleLogging(argv[0]);
// ...
LOG(INFO) &lt;&lt; "Found " &lt;&lt; num_cookies &lt;&lt; " cookies";
}
</pre>
<p>Google glog defines a series of macros that simplify many common logging
tasks. You can log messages by severity level, control logging
behavior from the command line, log based on conditionals, abort the
program when expected conditions are not met, introduce your own
verbose logging levels, and more. This document describes the
functionality supported by glog. Please note that this document
doesn't describe all features in this library, but the most useful
ones. If you want to find less common features, please check
header files under <code>src/glog</code> directory.
<h2> <A NAME=severity>Severity Level</A> </h2>
<p>
You can specify one of the following severity levels (in
increasing order of severity): <code>INFO</code>, <code>WARNING</code>,
<code>ERROR</code>, and <code>FATAL</code>.
Logging a <code>FATAL</code> message terminates the program (after the
message is logged).
Note that messages of a given severity are logged not only in the
logfile for that severity, but also in all logfiles of lower severity.
E.g., a message of severity <code>FATAL</code> will be logged to the
logfiles of severity <code>FATAL</code>, <code>ERROR</code>,
<code>WARNING</code>, and <code>INFO</code>.
<p>
The <code>DFATAL</code> severity logs a <code>FATAL</code> error in
debug mode (i.e., there is no <code>NDEBUG</code> macro defined), but
avoids halting the program in production by automatically reducing the
severity to <code>ERROR</code>.
<p>Unless otherwise specified, glog writes to the filename
"/tmp/&lt;program name&gt;.&lt;hostname&gt;.&lt;user name&gt;.log.&lt;severity level&gt;.&lt;date&gt;.&lt;time&gt;.&lt;pid&gt;"
(e.g., "/tmp/hello_world.example.com.hamaji.log.INFO.20080709-222411.10474").
By default, glog copies the log messages of severity level
<code>ERROR</code> or <code>FATAL</code> to standard error (stderr)
in addition to log files.
<h2><A NAME=flags>Setting Flags</A></h2>
<p>Several flags influence glog's output behavior.
If the <a href="https://github.com/gflags/gflags">Google
gflags library</a> is installed on your machine, the
<code>configure</code> script (see the INSTALL file in the package for
detail of this script) will automatically detect and use it,
allowing you to pass flags on the command line. For example, if you
want to turn the flag <code>--logtostderr</code> on, you can start
your application with the following command line:
<pre>
./your_application --logtostderr=1
</pre>
If the Google gflags library isn't installed, you set flags via
environment variables, prefixing the flag name with "GLOG_", e.g.
<pre>
GLOG_logtostderr=1 ./your_application
</pre>
<!-- TODO(hamaji): Fill the version number
<p>By glog version 0.x.x, you can use GLOG_* environment variables
even if you have gflags. If both an environment variable and a flag
are specified, the value specified by a flag wins. E.g., if GLOG_v=0
and --v=1, the verbosity will be 1, not 0.
-->
<p>The following flags are most commonly used:
<dl>
<dt><code>logtostderr</code> (<code>bool</code>, default=<code>false</code>)
<dd>Log messages to stderr instead of logfiles.<br>
Note: you can set binary flags to <code>true</code> by specifying
<code>1</code>, <code>true</code>, or <code>yes</code> (case
insensitive).
Also, you can set binary flags to <code>false</code> by specifying
<code>0</code>, <code>false</code>, or <code>no</code> (again, case
insensitive).
<dt><code>stderrthreshold</code> (<code>int</code>, default=2, which
is <code>ERROR</code>)
<dd>Copy log messages at or above this level to stderr in
addition to logfiles. The numbers of severity levels
<code>INFO</code>, <code>WARNING</code>, <code>ERROR</code>, and
<code>FATAL</code> are 0, 1, 2, and 3, respectively.
<dt><code>minloglevel</code> (<code>int</code>, default=0, which
is <code>INFO</code>)
<dd>Log messages at or above this level. Again, the numbers of
severity levels <code>INFO</code>, <code>WARNING</code>,
<code>ERROR</code>, and <code>FATAL</code> are 0, 1, 2, and 3,
respectively.
<dt><code>log_dir</code> (<code>string</code>, default="")
<dd>If specified, logfiles are written into this directory instead
of the default logging directory.
<dt><code>v</code> (<code>int</code>, default=0)
<dd>Show all <code>VLOG(m)</code> messages for <code>m</code> less or
equal the value of this flag. Overridable by --vmodule.
See <a href="#verbose">the section about verbose logging</a> for more
detail.
<dt><code>vmodule</code> (<code>string</code>, default="")
<dd>Per-module verbose level. The argument has to contain a
comma-separated list of &lt;module name&gt;=&lt;log level&gt;.
&lt;module name&gt;
is a glob pattern (e.g., <code>gfs*</code> for all modules whose name
starts with "gfs"), matched against the filename base
(that is, name ignoring .cc/.h./-inl.h).
&lt;log level&gt; overrides any value given by --v.
See also <a href="#verbose">the section about verbose logging</a>.
</dl>
<p>There are some other flags defined in logging.cc. Please grep the
source code for "DEFINE_" to see a complete list of all flags.
<p>You can also modify flag values in your program by modifying global
variables <code>FLAGS_*</code> . Most settings start working
immediately after you update <code>FLAGS_*</code> . The exceptions are
the flags related to destination files. For example, you might want to
set <code>FLAGS_log_dir</code> before
calling <code>google::InitGoogleLogging</code> . Here is an example:
<pre>
LOG(INFO) << "file";
// Most flags work immediately after updating values.
FLAGS_logtostderr = 1;
LOG(INFO) << "stderr";
FLAGS_logtostderr = 0;
// This won't change the log destination. If you want to set this
// value, you should do this before google::InitGoogleLogging .
FLAGS_log_dir = "/some/log/directory";
LOG(INFO) << "the same file";
</pre>
<h2><A NAME=conditional>Conditional / Occasional Logging</A></h2>
<p>Sometimes, you may only want to log a message under certain
conditions. You can use the following macros to perform conditional
logging:
<pre>
LOG_IF(INFO, num_cookies &gt; 10) &lt;&lt; "Got lots of cookies";
</pre>
The "Got lots of cookies" message is logged only when the variable
<code>num_cookies</code> exceeds 10.
If a line of code is executed many times, it may be useful to only log
a message at certain intervals. This kind of logging is most useful
for informational messages.
<pre>
LOG_EVERY_N(INFO, 10) &lt;&lt; "Got the " &lt;&lt; google::COUNTER &lt;&lt; "th cookie";
</pre>
<p>The above line outputs a log messages on the 1st, 11th,
21st, ... times it is executed. Note that the special
<code>google::COUNTER</code> value is used to identify which repetition is
happening.
<p>You can combine conditional and occasional logging with the
following macro.
<pre>
LOG_IF_EVERY_N(INFO, (size &gt; 1024), 10) &lt;&lt; "Got the " &lt;&lt; google::COUNTER
&lt;&lt; "th big cookie";
</pre>
<p>Instead of outputting a message every nth time, you can also limit
the output to the first n occurrences:
<pre>
LOG_FIRST_N(INFO, 20) &lt;&lt; "Got the " &lt;&lt; google::COUNTER &lt;&lt; "th cookie";
</pre>
<p>Outputs log messages for the first 20 times it is executed. Again,
the <code>google::COUNTER</code> identifier indicates which repetition is
happening.
<h2><A NAME=debug>Debug Mode Support</A></h2>
<p>Special "debug mode" logging macros only have an effect in debug
mode and are compiled away to nothing for non-debug mode
compiles. Use these macros to avoid slowing down your production
application due to excessive logging.
<pre>
DLOG(INFO) &lt;&lt; "Found cookies";
DLOG_IF(INFO, num_cookies &gt; 10) &lt;&lt; "Got lots of cookies";
DLOG_EVERY_N(INFO, 10) &lt;&lt; "Got the " &lt;&lt; google::COUNTER &lt;&lt; "th cookie";
</pre>
<h2><A NAME=check>CHECK Macros</A></h2>
<p>It is a good practice to check expected conditions in your program
frequently to detect errors as early as possible. The
<code>CHECK</code> macro provides the ability to abort the application
when a condition is not met, similar to the <code>assert</code> macro
defined in the standard C library.
<p><code>CHECK</code> aborts the application if a condition is not
true. Unlike <code>assert</code>, it is *not* controlled by
<code>NDEBUG</code>, so the check will be executed regardless of
compilation mode. Therefore, <code>fp-&gt;Write(x)</code> in the
following example is always executed:
<pre>
CHECK(fp-&gt;Write(x) == 4) &lt;&lt; "Write failed!";
</pre>
<p>There are various helper macros for
equality/inequality checks - <code>CHECK_EQ</code>,
<code>CHECK_NE</code>, <code>CHECK_LE</code>, <code>CHECK_LT</code>,
<code>CHECK_GE</code>, and <code>CHECK_GT</code>.
They compare two values, and log a
<code>FATAL</code> message including the two values when the result is
not as expected. The values must have <code>operator&lt;&lt;(ostream,
...)</code> defined.
<p>You may append to the error message like so:
<pre>
CHECK_NE(1, 2) &lt;&lt; ": The world must be ending!";
</pre>
<p>We are very careful to ensure that each argument is evaluated exactly
once, and that anything which is legal to pass as a function argument is
legal here. In particular, the arguments may be temporary expressions
which will end up being destroyed at the end of the apparent statement,
for example:
<pre>
CHECK_EQ(string("abc")[1], 'b');
</pre>
<p>The compiler reports an error if one of the arguments is a
pointer and the other is NULL. To work around this, simply static_cast
NULL to the type of the desired pointer.
<pre>
CHECK_EQ(some_ptr, static_cast&lt;SomeType*&gt;(NULL));
</pre>
<p>Better yet, use the CHECK_NOTNULL macro:
<pre>
CHECK_NOTNULL(some_ptr);
some_ptr-&gt;DoSomething();
</pre>
<p>Since this macro returns the given pointer, this is very useful in
constructor initializer lists.
<pre>
struct S {
S(Something* ptr) : ptr_(CHECK_NOTNULL(ptr)) {}
Something* ptr_;
};
</pre>
<p>Note that you cannot use this macro as a C++ stream due to this
feature. Please use <code>CHECK_EQ</code> described above to log a
custom message before aborting the application.
<p>If you are comparing C strings (char *), a handy set of macros
performs case sensitive as well as case insensitive comparisons -
<code>CHECK_STREQ</code>, <code>CHECK_STRNE</code>,
<code>CHECK_STRCASEEQ</code>, and <code>CHECK_STRCASENE</code>. The
CASE versions are case-insensitive. You can safely pass <code>NULL</code>
pointers for this macro. They treat <code>NULL</code> and any
non-<code>NULL</code> string as not equal. Two <code>NULL</code>s are
equal.
<p>Note that both arguments may be temporary strings which are
destructed at the end of the current "full expression"
(e.g., <code>CHECK_STREQ(Foo().c_str(), Bar().c_str())</code> where
<code>Foo</code> and <code>Bar</code> return C++'s
<code>std::string</code>).
<p>The <code>CHECK_DOUBLE_EQ</code> macro checks the equality of two
floating point values, accepting a small error margin.
<code>CHECK_NEAR</code> accepts a third floating point argument, which
specifies the acceptable error margin.
<h2><A NAME=verbose>Verbose Logging</A></h2>
<p>When you are chasing difficult bugs, thorough log messages are very
useful. However, you may want to ignore too verbose messages in usual
development. For such verbose logging, glog provides the
<code>VLOG</code> macro, which allows you to define your own numeric
logging levels. The <code>--v</code> command line option controls
which verbose messages are logged:
<pre>
VLOG(1) &lt;&lt; "I'm printed when you run the program with --v=1 or higher";
VLOG(2) &lt;&lt; "I'm printed when you run the program with --v=2 or higher";
</pre>
<p>With <code>VLOG</code>, the lower the verbose level, the more
likely messages are to be logged. For example, if
<code>--v==1</code>, <code>VLOG(1)</code> will log, but
<code>VLOG(2)</code> will not log. This is opposite of the severity
level, where <code>INFO</code> is 0, and <code>ERROR</code> is 2.
<code>--minloglevel</code> of 1 will log <code>WARNING</code> and
above. Though you can specify any integers for both <code>VLOG</code>
macro and <code>--v</code> flag, the common values for them are small
positive integers. For example, if you write <code>VLOG(0)</code>,
you should specify <code>--v=-1</code> or lower to silence it. This
is less useful since we may not want verbose logs by default in most
cases. The <code>VLOG</code> macros always log at the
<code>INFO</code> log level (when they log at all).
<p>Verbose logging can be controlled from the command line on a
per-module basis:
<pre>
--vmodule=mapreduce=2,file=1,gfs*=3 --v=0
</pre>
<p>will:
<ul>
<li>a. Print VLOG(2) and lower messages from mapreduce.{h,cc}
<li>b. Print VLOG(1) and lower messages from file.{h,cc}
<li>c. Print VLOG(3) and lower messages from files prefixed with "gfs"
<li>d. Print VLOG(0) and lower messages from elsewhere
</ul>
<p>The wildcarding functionality shown by (c) supports both '*'
(matches 0 or more characters) and '?' (matches any single character)
wildcards. Please also check the section about <a
href="#flags">command line flags</a>.
<p>There's also <code>VLOG_IS_ON(n)</code> "verbose level" condition
macro. This macro returns true when the <code>--v</code> is equal or
greater than <code>n</code>. To be used as
<pre>
if (VLOG_IS_ON(2)) {
// do some logging preparation and logging
// that can't be accomplished with just VLOG(2) &lt;&lt; ...;
}
</pre>
<p>Verbose level condition macros <code>VLOG_IF</code>,
<code>VLOG_EVERY_N</code> and <code>VLOG_IF_EVERY_N</code> behave
analogous to <code>LOG_IF</code>, <code>LOG_EVERY_N</code>,
<code>LOF_IF_EVERY</code>, but accept a numeric verbosity level as
opposed to a severity level.
<pre>
VLOG_IF(1, (size &gt; 1024))
&lt;&lt; "I'm printed when size is more than 1024 and when you run the "
"program with --v=1 or more";
VLOG_EVERY_N(1, 10)
&lt;&lt; "I'm printed every 10th occurrence, and when you run the program "
"with --v=1 or more. Present occurence is " &lt;&lt; google::COUNTER;
VLOG_IF_EVERY_N(1, (size &gt; 1024), 10)
&lt;&lt; "I'm printed on every 10th occurence of case when size is more "
" than 1024, when you run the program with --v=1 or more. ";
"Present occurence is " &lt;&lt; google::COUNTER;
</pre>
<h2> <A name="signal">Failure Signal Handler</A> </h2>
<p>
The library provides a convenient signal handler that will dump useful
information when the program crashes on certain signals such as SIGSEGV.
The signal handler can be installed by
google::InstallFailureSignalHandler(). The following is an example of output
from the signal handler.
<pre>
*** Aborted at 1225095260 (unix time) try "date -d @1225095260" if you are using GNU date ***
*** SIGSEGV (@0x0) received by PID 17711 (TID 0x7f893090a6f0) from PID 0; stack trace: ***
PC: @ 0x412eb1 TestWaitingLogSink::send()
@ 0x7f892fb417d0 (unknown)
@ 0x412eb1 TestWaitingLogSink::send()
@ 0x7f89304f7f06 google::LogMessage::SendToLog()
@ 0x7f89304f35af google::LogMessage::Flush()
@ 0x7f89304f3739 google::LogMessage::~LogMessage()
@ 0x408cf4 TestLogSinkWaitTillSent()
@ 0x4115de main
@ 0x7f892f7ef1c4 (unknown)
@ 0x4046f9 (unknown)
</pre>
<p>
By default, the signal handler writes the failure dump to the standard
error. You can customize the destination by InstallFailureWriter().
<h2> <A name="misc">Miscellaneous Notes</A> </h2>
<h3><A NAME=message>Performance of Messages</A></h3>
<p>The conditional logging macros provided by glog (e.g.,
<code>CHECK</code>, <code>LOG_IF</code>, <code>VLOG</code>, ...) are
carefully implemented and don't execute the right hand side
expressions when the conditions are false. So, the following check
may not sacrifice the performance of your application.
<pre>
CHECK(obj.ok) &lt;&lt; obj.CreatePrettyFormattedStringButVerySlow();
</pre>
<h3><A NAME=failure>User-defined Failure Function</A></h3>
<p><code>FATAL</code> severity level messages or unsatisfied
<code>CHECK</code> condition terminate your program. You can change
the behavior of the termination by
<code>InstallFailureFunction</code>.
<pre>
void YourFailureFunction() {
// Reports something...
exit(1);
}
int main(int argc, char* argv[]) {
google::InstallFailureFunction(&amp;YourFailureFunction);
}
</pre>
<p>By default, glog tries to dump stacktrace and makes the program
exit with status 1. The stacktrace is produced only when you run the
program on an architecture for which glog supports stack tracing (as
of September 2008, glog supports stack tracing for x86 and x86_64).
<h3><A NAME=raw>Raw Logging</A></h3>
<p>The header file <code>&lt;glog/raw_logging.h&gt;</code> can be
used for thread-safe logging, which does not allocate any memory or
acquire any locks. Therefore, the macros defined in this
header file can be used by low-level memory allocation and
synchronization code.
Please check <code>src/glog/raw_logging.h.in</code> for detail.
</p>
<h3><A NAME=plog>Google Style perror()</A></h3>
<p><code>PLOG()</code> and <code>PLOG_IF()</code> and
<code>PCHECK()</code> behave exactly like their <code>LOG*</code> and
<code>CHECK</code> equivalents with the addition that they append a
description of the current state of errno to their output lines.
E.g.
<pre>
PCHECK(write(1, NULL, 2) &gt;= 0) &lt;&lt; "Write NULL failed";
</pre>
<p>This check fails with the following error message.
<pre>
F0825 185142 test.cc:22] Check failed: write(1, NULL, 2) &gt;= 0 Write NULL failed: Bad address [14]
</pre>
<h3><A NAME=syslog>Syslog</A></h3>
<p><code>SYSLOG</code>, <code>SYSLOG_IF</code>, and
<code>SYSLOG_EVERY_N</code> macros are available.
These log to syslog in addition to the normal logs. Be aware that
logging to syslog can drastically impact performance, especially if
syslog is configured for remote logging! Make sure you understand the
implications of outputting to syslog before you use these macros. In
general, it's wise to use these macros sparingly.
<h3><A NAME=strip>Strip Logging Messages</A></h3>
<p>Strings used in log messages can increase the size of your binary
and present a privacy concern. You can therefore instruct glog to
remove all strings which fall below a certain severity level by using
the GOOGLE_STRIP_LOG macro:
<p>If your application has code like this:
<pre>
#define GOOGLE_STRIP_LOG 1 // this must go before the #include!
#include &lt;glog/logging.h&gt;
</pre>
<p>The compiler will remove the log messages whose severities are less
than the specified integer value. Since
<code>VLOG</code> logs at the severity level <code>INFO</code>
(numeric value <code>0</code>),
setting <code>GOOGLE_STRIP_LOG</code> to 1 or greater removes
all log messages associated with <code>VLOG</code>s as well as
<code>INFO</code> log statements.
<h3><A NAME=strip>Automatically Remove Old Logs</A></h3>
<p>To enable the log cleaner:
<pre>
google::EnableLogCleaner(3); // keep your logs for 3 days
</pre>
And then Google glog will check if there are overdue logs whenever
a flush is performed. In this example, any log file from your project whose
last modified time is greater than 3 days will be unlink()ed.
<p>This feature can be disabled at any time (if it has been enabled)
<pre>
google::DisableLogCleaner();
</pre>
<h3><A NAME=windows>Notes for Windows users</A></h3>
<p>Google glog defines a severity level <code>ERROR</code>, which is
also defined in <code>windows.h</code> . You can make glog not define
<code>INFO</code>, <code>WARNING</code>, <code>ERROR</code>,
and <code>FATAL</code> by defining
<code>GLOG_NO_ABBREVIATED_SEVERITIES</code> before
including <code>glog/logging.h</code> . Even with this macro, you can
still use the iostream like logging facilities:
<pre>
#define GLOG_NO_ABBREVIATED_SEVERITIES
#include &lt;windows.h&gt;
#include &lt;glog/logging.h&gt;
// ...
LOG(ERROR) &lt;&lt; "This should work";
LOG_IF(ERROR, x &gt; y) &lt;&lt; "This should be also OK";
</pre>
<p>
However, you cannot
use <code>INFO</code>, <code>WARNING</code>, <code>ERROR</code>,
and <code>FATAL</code> anymore for functions defined
in <code>glog/logging.h</code> .
<pre>
#define GLOG_NO_ABBREVIATED_SEVERITIES
#include &lt;windows.h&gt;
#include &lt;glog/logging.h&gt;
// ...
// This won't work.
// google::FlushLogFiles(google::ERROR);
// Use this instead.
google::FlushLogFiles(google::GLOG_ERROR);
</pre>
<p>
If you don't need <code>ERROR</code> defined
by <code>windows.h</code>, there are a couple of more workarounds
which sometimes don't work:
<ul>
<li>#define <code>WIN32_LEAN_AND_MEAN</code> or <code>NOGDI</code>
<strong>before</strong> you #include <code>windows.h</code> .
<li>#undef <code>ERROR</code> <strong>after</strong> you #include
<code>windows.h</code> .
</ul>
<p>See <a href="http://code.google.com/p/google-glog/issues/detail?id=33">
this issue</a> for more detail.

dnl @summary figure out how to build C programs using POSIX threads
dnl
dnl This macro figures out how to build C programs using POSIX threads.
dnl It sets the PTHREAD_LIBS output variable to the threads library and
dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
dnl C compiler flags that are needed. (The user can also force certain
dnl compiler flags/libs to be tested by setting these environment
dnl variables.)
dnl
dnl Also sets PTHREAD_CC to any special C compiler that is needed for
dnl multi-threaded programs (defaults to the value of CC otherwise).
dnl (This is necessary on AIX to use the special cc_r compiler alias.)
dnl
dnl NOTE: You are assumed to not only compile your program with these
dnl flags, but also link it with them as well. e.g. you should link
dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
dnl $LIBS
dnl
dnl If you are only building threads programs, you may wish to use
dnl these variables in your default LIBS, CFLAGS, and CC:
dnl
dnl LIBS="$PTHREAD_LIBS $LIBS"
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
dnl CC="$PTHREAD_CC"
dnl
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
dnl default action will define HAVE_PTHREAD.
dnl
dnl Please let the authors know if this macro fails on any platform, or
dnl if you have any other suggestions or comments. This macro was based
dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
dnl We are also grateful for the helpful feedback of numerous users.

# lt~obsolete.m4 -- aclocal satisfying obsolete definitions. -*-Autoconf-*-

# serial 5 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

// This file is a compatibility layer that defines Google's version of
// command line flags that are used for configuration.
//
// We 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_logtostderr;
// 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.

// 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.

// This file is needed for windows -- unittests are not part of the
// glog 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 GOOGLE_GLOG_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 GOOGLE_GLOG_DLL_DECL to do a dllimport instead of a dllexport.
//
// The reason we need this extra GOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS
// variable is in case people want to set GOOGLE_GLOG_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
// GOOGLE_GLOG_DLL_DECL and GOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS explicitly.
//
// NOTE: This file is equivalent to config.h on non-windows systems,
// which never defined GOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS and always
// define GOOGLE_GLOG_DLL_DECL to the empty string.

// An async-signal-safe and thread-safe demangler for Itanium C++ ABI
// (aka G++ V3 ABI).
// The demangler is implemented to be used in async signal handlers to
// symbolize stack traces. We cannot use libstdc++'s
// abi::__cxa_demangle() in such signal handlers since it's not async
// signal safe (it uses malloc() internally).
//
// Note that this demangler doesn't support full demangling. More
// specifically, it doesn't print types of function parameters and
// types of template arguments. It just skips them. However, it's
// still very useful to extract basic information such as class,
// function, constructor, destructor, and operator names.
//
// See the implementation note in demangle.cc if you are interested.
//
// Example:
//
// | Mangled Name | The Demangler | abi::__cxa_demangle()
// |---------------|---------------|-----------------------
// | _Z1fv | f() | f()
// | _Z1fi | f() | f(int)
// | _Z3foo3bar | foo() | foo(bar)
// | _Z1fIiEvi | f<>() | void f<int>(int)
// | _ZN1N1fE | N::f | N::f
// | _ZN3Foo3BarEv | Foo::Bar() | Foo::Bar()
// | _Zrm1XS_" | operator%() | operator%(X, X)
// | _ZN3FooC1Ev | Foo::Foo() | Foo::Foo()
// | _Z1fSs | f() | f(std::basic_string<char,
// | | | std::char_traits<char>,
// | | | std::allocator<char> >)
//
// See the unit test for more examples.
//
// Note: we might want to write demanglers for ABIs other than Itanium
// C++ ABI in the future.

// found via ADL, they must be #included before they're used, which requires
// this header to be included before apparently independent other headers.
//
// For example, base/logging.h defines various template functions to implement
// CHECK_EQ(x, y) and stream x and y into the log in the event the check fails.
// It does so via the function template MakeCheckOpValueString:
// template<class T>
// void MakeCheckOpValueString(strstream* ss, const T& v) {
// (*ss) << v;
// }
// Because 'glog/logging.h' is included before 'glog/stl_logging.h',
// subsequent CHECK_EQ(v1, v2) for vector<...> typed variable v1 and v2 can only
// find these operator definitions via ADL.
//
// Even this solution has problems -- it may pull unintended operators into the
// namespace as well, allowing them to also be found via ADL, and creating code
// that only works with a particular order of includes. Long term, we need to
// move all of the *definitions* into namespace std, bet we need to ensure no
// one references them first. This lets us take that step. We cannot define them
// in both because that would create ambiguous overloads when both are found.

// Defines the VLOG_IS_ON macro that controls the variable-verbosity
// conditional logging.
//
// It's used by VLOG and VLOG_IF in logging.h
// and by RAW_VLOG in raw_logging.h to trigger the logging.
//
// It can also be used directly e.g. like this:
// if (VLOG_IS_ON(2)) {
// // do some logging preparation and logging
// // that can't be accomplished e.g. via just VLOG(2) << ...;
// }
//
// The truth value that VLOG_IS_ON(level) returns is determined by
// the three verbosity level flags:
// --v=<n> Gives the default maximal active V-logging level;
// 0 is the default.
// Normally positive values are used for V-logging levels.
// --vmodule=<str> Gives the per-module maximal V-logging levels to override
// the value given by --v.
// E.g. "my_module=2,foo*=3" would change the logging level
// for all code in source files "my_module.*" and "foo*.*"
// ("-inl" suffixes are also disregarded for this matching).
//
// SetVLOGLevel helper function is provided to do limited dynamic control over
// V-logging by overriding the per-module settings given via --vmodule flag.
//
// CAVEAT: --vmodule functionality is not available in non gcc compilers.
