-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' file for
-instructions specific to this package.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system.
-
- Running `configure' might take a while. While running, it prints
- some messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
- 6. Often, you can also type `make uninstall' to remove the installed
- files again.
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that the
-`configure' script does not know about. Run `./configure --help' for
-details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you can use GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory. After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-Installation Names
-==================
-
-By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' cannot figure out automatically,
-but needs to determine by the type of machine the package will run on.
-Usually, assuming the package is built to be run on the _same_
-architectures, `configure' can figure that out, but if it prints a
-message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share, you
-can create a site shell script called `config.site' that gives default
-values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug. Until the bug is fixed you can use this workaround:
-
- CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-
-<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(<a
-particular <a href="#severity">severity level</a>>), e.g.
-
-<pre>
- #include <glog/logging.h>
-
- int main(int argc, char* argv[]) {
- // Initialize Google's logging library.
- google::InitGoogleLogging(argv[0]);
-
- // ...
- LOG(INFO) << "Found " << num_cookies << " 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/<program name>.<hostname>.<user name>.log.<severity level>.<date>.<time>.<pid>"
-(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="http://code.google.com/p/google-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 <module name>=<log level>.
-<module name>
-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).
-<log level> 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 > 10) << "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) << "Got the " << google::COUNTER << "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 > 1024), 10) << "Got the " << google::COUNTER
- << "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) << "Got the " << google::COUNTER << "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) << "Found cookies";
-
- DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-
- DLOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "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->Write(x)</code> in the
-following example is always executed:
-
-<pre>
- CHECK(fp->Write(x) == 4) << "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<<(ostream,
-...)</code> defined.
-
-<p>You may append to the error message like so:
-
-<pre>
- CHECK_NE(1, 2) << ": 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<SomeType*>(NULL));
-</pre>
-
-<p>Better yet, use the CHECK_NOTNULL macro:
-
-<pre>
- CHECK_NOTNULL(some_ptr);
- some_ptr->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) << "I'm printed when you run the program with --v=1 or higher";
- VLOG(2) << "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) << ...;
- }
-</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 > 1024))
- << "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)
- << "I'm printed every 10th occurrence, and when you run the program "
- "with --v=1 or more. Present occurence is " << google::COUNTER;
- VLOG_IF_EVERY_N(1, (size > 1024), 10)
- << "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 " << 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()

- @ 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) << 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(&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><glog/raw_logging.h></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) >= 0) << "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) >= 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 <glog/logging.h>
-</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=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 <windows.h>
- #include <glog/logging.h>
-
- // ...
-
- LOG(ERROR) << "This should work";
- LOG_IF(ERROR, x > y) << "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 <windows.h>
- #include <glog/logging.h>
-
- // ...
-
- // 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>
-

-this issue</a> for more detail.

-// 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.

-// Implementation note: the following code is a straightforward

-//
-// - Support GNU extensions not defined in the Itanium C++ ABI
-// - <prefix> and <template-prefix> are combined to avoid infinite loop
-// - Reorder patterns to shorten the code
-// - Reorder patterns to give greedier functions precedence
-// We'll mark "Less greedy than" for these cases in the code
-//
-// Each parsing function changes the state and returns true on
-// success. Otherwise, don't change the state and returns false. To
-// ensure that the state isn't changed in the latter case, we save the
-// original state before we call more than one parsing functions
-// consecutively with &&, and restore the state if unsuccessful. See
-// ParseEncoding() as an example of this convention. We follow the
-// convention throughout the code.
-//
-// Originally we tried to do demangling without following the full ABI
-// syntax but it turned out we needed to follow the full syntax to
-// parse complicated cases like nested template arguments. Note that
-// implementing a full-fledged demangler isn't trivial (libiberty's
-// cp-demangle.c has +4300 lines).
-//
-// Note that (foo) in <(foo) ...> is a modifier to be ignored.

-// 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.

-// Make a bunch of macros for logging. The way to log things is to stream
-// things to LOG(<a particular severity level>). E.g.,
-//
-// LOG(INFO) << "Found " << num_cookies << " cookies";
-//
-// You can capture log messages in a string, rather than reporting them
-// immediately:
-//
-// vector<string> errors;
-// LOG_STRING(ERROR, &errors) << "Couldn't parse cookie #" << cookie_num;
-//
-// This pushes back the new error onto 'errors'; if given a NULL pointer,
-// it reports the error via LOG(ERROR).
-//
-// You can also do conditional logging:
-//
-// LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-// You can also do occasional logging (log every n'th occurrence of an
-// event):
-//
-// LOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-//
-// The above will cause log messages to be output on the 1st, 11th, 21st, ...
-// times it is executed. Note that the special google::COUNTER value is used
-// to identify which repetition is happening.
-//
-// You can also do occasional conditional logging (log every n'th
-// occurrence of an event, when condition is satisfied):
-//
-// LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << google::COUNTER
-// << "th big cookie";
-//
-// You can log messages the first N times your code executes a line. E.g.
-//
-// LOG_FIRST_N(INFO, 20) << "Got the " << google::COUNTER << "th cookie";
-//
-// Outputs log messages for the first 20 times it is executed.
-//
-// Analogous SYSLOG, SYSLOG_IF, and SYSLOG_EVERY_N macros are available.
-// These log to syslog as well as to the normal logs. If you use these at
-// all, you need to be aware that syslog can drastically reduce performance,
-// especially if it is configured for remote logging! Don't use these
-// unless you fully understand this and have a concrete need to use them.
-// Even then, try to minimize your use of them.
-//
-// There are also "debug mode" logging macros like the ones above:
-//
-// DLOG(INFO) << "Found cookies";
-//

-// All "debug mode" logging is compiled away to nothing for non-debug mode
-// compiles.
-//
-// We also have
-//
-// LOG_ASSERT(assertion);
-// DLOG_ASSERT(assertion);
-//
-// which is syntactic sugar for {,D}LOG_IF(FATAL, assert fails) << assertion;
-//
-// There are "verbose level" logging macros. They look like
-//
-// VLOG(1) << "I'm printed when you run the program with --v=1 or more";
-// VLOG(2) << "I'm printed when you run the program with --v=2 or more";
-//
-// These always log at the INFO log level (when they log at all).
-// The verbose logging can also be turned on module-by-module. For instance,
-// --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
-// will cause:
-// a. VLOG(2) and lower messages to be printed from mapreduce.{h,cc}
-// b. VLOG(1) and lower messages to be printed from file.{h,cc}
-// c. VLOG(3) and lower messages to be printed from files prefixed with "gfs"
-// d. VLOG(0) and lower messages to be printed from elsewhere
-//
-// The wildcarding functionality shown by (c) supports both '*' (match
-// 0 or more characters) and '?' (match any single character) wildcards.
-//
-// There's also VLOG_IS_ON(n) "verbose level" condition macro. To be used as
-//
-// if (VLOG_IS_ON(2)) {
-// // do some logging preparation and logging
-// // that can't be accomplished with just VLOG(2) << ...;
-// }
-//
-// There are also VLOG_IF, VLOG_EVERY_N and VLOG_IF_EVERY_N "verbose level"
-// condition macros for sample cases, when some extra computation and
-// preparation for logs is not needed.
-// VLOG_IF(1, (size > 1024))
-// << "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)
-// << "I'm printed every 10th occurrence, and when you run the program "
-// "with --v=1 or more. Present occurence is " << google::COUNTER;
-// VLOG_IF_EVERY_N(1, (size > 1024), 10)
-// << "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 " << google::COUNTER;
-//
-// The supported severity levels for macros that allow you to specify one
-// are (in increasing order of severity) INFO, WARNING, ERROR, and FATAL.
-// 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 FATAL will be logged to the logfiles of
-// severity FATAL, ERROR, WARNING, and INFO.
-//
-// There is also the special severity of DFATAL, which logs FATAL in
-// debug mode, ERROR in normal mode.
-//
-// Very important: logging a message at the FATAL severity level causes
-// the program to terminate (after the message is logged).
-//
-// Unless otherwise specified, logs will be written to the filename
-// "<program name>.<hostname>.<user name>.log.<severity level>.", followed
-// by the date, time, and pid (you can't prevent the date, time, and pid
-// from being in the filename).
-//
-// The logging code takes two flags:
-// --v=# set the verbose level
-// --logtostderr log all the messages to stderr instead of to logfiles
-
-// LOG LINE PREFIX FORMAT
-//
-// Log lines have this form:
-//
-// Lmmdd hh:mm:ss.uuuuuu threadid file:line] msg...
-//
-// where the fields are defined as follows:
-//
-// L A single character, representing the log level
-// (eg 'I' for INFO)
-// mm The month (zero padded; ie May is '05')
-// dd The day (zero padded)
-// hh:mm:ss.uuuuuu Time in hours, minutes and fractional seconds
-// threadid The space-padded thread ID as returned by GetTID()
-// (this matches the PID on Linux)
-// file The file name
-// line The line number
-// msg The user-supplied message
-//
-// Example:
-//
-// I1103 11:57:31.739339 24395 google.cc:2341] Command line: ./some_prog
-// I1103 11:57:31.739403 24395 google.cc:2342] Process id 24395
-//
-// NOTE: although the microseconds are useful for comparing events on
-// a single machine, clocks on different machines may not be well
-// synchronized. Hence, use caution when comparing the low bits of
-// timestamps from different machines.

-// 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.

-// This library provides Symbolize() function that symbolizes program
-// counters to their corresponding symbol names on linux platforms.
-// This library has a minimal implementation of an ELF symbol table
-// reader (i.e. it doesn't depend on libelf, etc.).
-//
-// The algorithm used in Symbolize() is as follows.
-//
-// 1. Go through a list of maps in /proc/self/maps and find the map
-// containing the program counter.
-//
-// 2. Open the mapped file and find a regular symbol table inside.
-// Iterate over symbols in the symbol table and look for the symbol
-// containing the program counter. If such a symbol is found,
-// obtain the symbol name, and demangle the symbol if possible.
-// If the symbol isn't found in the regular symbol table (binary is
-// stripped), try the same thing with a dynamic symbol table.
-//
-// Note that Symbolize() is originally implemented to be used in
-// FailureSignalHandler() in base/google.cc. Hence it doesn't use
-// malloc() and other unsafe operations. It should be both
-// thread-safe and async-signal-safe.

-// 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.

-// Make a bunch of macros for logging. The way to log things is to stream
-// things to LOG(<a particular severity level>). E.g.,
-//
-// LOG(INFO) << "Found " << num_cookies << " cookies";
-//
-// You can capture log messages in a string, rather than reporting them
-// immediately:
-//
-// vector<string> errors;
-// LOG_STRING(ERROR, &errors) << "Couldn't parse cookie #" << cookie_num;
-//
-// This pushes back the new error onto 'errors'; if given a NULL pointer,
-// it reports the error via LOG(ERROR).
-//
-// You can also do conditional logging:
-//
-// LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-// You can also do occasional logging (log every n'th occurrence of an
-// event):
-//
-// LOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-//
-// The above will cause log messages to be output on the 1st, 11th, 21st, ...
-// times it is executed. Note that the special google::COUNTER value is used
-// to identify which repetition is happening.
-//
-// You can also do occasional conditional logging (log every n'th
-// occurrence of an event, when condition is satisfied):
-//
-// LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << google::COUNTER
-// << "th big cookie";
-//
-// You can log messages the first N times your code executes a line. E.g.
-//
-// LOG_FIRST_N(INFO, 20) << "Got the " << google::COUNTER << "th cookie";
-//
-// Outputs log messages for the first 20 times it is executed.
-//
-// Analogous SYSLOG, SYSLOG_IF, and SYSLOG_EVERY_N macros are available.
-// These log to syslog as well as to the normal logs. If you use these at
-// all, you need to be aware that syslog can drastically reduce performance,
-// especially if it is configured for remote logging! Don't use these
-// unless you fully understand this and have a concrete need to use them.
-// Even then, try to minimize your use of them.
-//
-// There are also "debug mode" logging macros like the ones above:
-//
-// DLOG(INFO) << "Found cookies";
-//
-// DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-// DLOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-//
-// All "debug mode" logging is compiled away to nothing for non-debug mode
-// compiles.
-//
-// We also have
-//
-// LOG_ASSERT(assertion);
-// DLOG_ASSERT(assertion);
-//
-// which is syntactic sugar for {,D}LOG_IF(FATAL, assert fails) << assertion;
-//
-// There are "verbose level" logging macros. They look like
-//
-// VLOG(1) << "I'm printed when you run the program with --v=1 or more";
-// VLOG(2) << "I'm printed when you run the program with --v=2 or more";
-//
-// These always log at the INFO log level (when they log at all).
-// The verbose logging can also be turned on module-by-module. For instance,
-// --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
-// will cause:
-// a. VLOG(2) and lower messages to be printed from mapreduce.{h,cc}
-// b. VLOG(1) and lower messages to be printed from file.{h,cc}
-// c. VLOG(3) and lower messages to be printed from files prefixed with "gfs"
-// d. VLOG(0) and lower messages to be printed from elsewhere
-//
-// The wildcarding functionality shown by (c) supports both '*' (match
-// 0 or more characters) and '?' (match any single character) wildcards.
-//
-// There's also VLOG_IS_ON(n) "verbose level" condition macro. To be used as
-//
-// if (VLOG_IS_ON(2)) {
-// // do some logging preparation and logging
-// // that can't be accomplished with just VLOG(2) << ...;
-// }
-//
-// There are also VLOG_IF, VLOG_EVERY_N and VLOG_IF_EVERY_N "verbose level"
-// condition macros for sample cases, when some extra computation and
-// preparation for logs is not needed.
-// VLOG_IF(1, (size > 1024))
-// << "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)
-// << "I'm printed every 10th occurrence, and when you run the program "
-// "with --v=1 or more. Present occurence is " << google::COUNTER;
-// VLOG_IF_EVERY_N(1, (size > 1024), 10)
-// << "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 " << google::COUNTER;
-//
-// The supported severity levels for macros that allow you to specify one
-// are (in increasing order of severity) INFO, WARNING, ERROR, and FATAL.
-// 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 FATAL will be logged to the logfiles of
-// severity FATAL, ERROR, WARNING, and INFO.
-//
-// There is also the special severity of DFATAL, which logs FATAL in
-// debug mode, ERROR in normal mode.
-//
-// Very important: logging a message at the FATAL severity level causes
-// the program to terminate (after the message is logged).
-//
-// Unless otherwise specified, logs will be written to the filename
-// "<program name>.<hostname>.<user name>.log.<severity level>.", followed
-// by the date, time, and pid (you can't prevent the date, time, and pid
-// from being in the filename).
-//
-// The logging code takes two flags:
-// --v=# set the verbose level
-// --logtostderr log all the messages to stderr instead of to logfiles
-
-// LOG LINE PREFIX FORMAT
-//
-// Log lines have this form:
-//
-// Lmmdd hh:mm:ss.uuuuuu threadid file:line] msg...
-//
-// where the fields are defined as follows:
-//
-// L A single character, representing the log level
-// (eg 'I' for INFO)
-// mm The month (zero padded; ie May is '05')
-// dd The day (zero padded)
-// hh:mm:ss.uuuuuu Time in hours, minutes and fractional seconds
-// threadid The space-padded thread ID as returned by GetTID()
-// (this matches the PID on Linux)
-// file The file name
-// line The line number
-// msg The user-supplied message
-//
-// Example:
-//
-// I1103 11:57:31.739339 24395 google.cc:2341] Command line: ./some_prog
-// I1103 11:57:31.739403 24395 google.cc:2342] Process id 24395
-//
-// NOTE: although the microseconds are useful for comparing events on
-// a single machine, clocks on different machines may not be well
-// synchronized. Hence, use caution when comparing the low bits of
-// timestamps from different machines.

-// 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.
