(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 - ./vcpkg integrate install - ./vcpkg install glog - -The glog port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository. - - -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.

How To Use Google Logging Library (glog)

-(as of -) - -
- -

Introduction

- -

Google glog 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 severity level>), e.g. - -

-   #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";
-   }
-
- -

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 src/glog directory. - -

Severity Level

- -

-You can specify one of the following severity levels (in -increasing order of severity): INFO, WARNING, -ERROR, and FATAL. -Logging a FATAL 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 FATAL will be logged to the -logfiles of severity FATAL, ERROR, -WARNING, and INFO. - -

-The DFATAL severity logs a FATAL error in -debug mode (i.e., there is no NDEBUG macro defined), but -avoids halting the program in production by automatically reducing the -severity to ERROR. - -

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 -ERROR or FATAL to standard error (stderr) -in addition to log files. - -

Setting Flags

- -

Several flags influence glog's output behavior. -If the Google -gflags library is installed on your machine, the -configure 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 --logtostderr on, you can start -your application with the following command line: - -

-   ./your_application --logtostderr=1
-
- -If the Google gflags library isn't installed, you set flags via -environment variables, prefixing the flag name with "GLOG_", e.g. - -
-   GLOG_logtostderr=1 ./your_application
-
- - - -

The following flags are most commonly used: - -

-
logtostderr (bool, default=false) -
Log messages to stderr instead of logfiles.
-Note: you can set binary flags to true by specifying -1, true, or yes (case -insensitive). -Also, you can set binary flags to false by specifying -0, false, or no (again, case -insensitive). -
stderrthreshold (int, default=2, which -is ERROR) -
Copy log messages at or above this level to stderr in -addition to logfiles. The numbers of severity levels -INFO, WARNING, ERROR, and -FATAL are 0, 1, 2, and 3, respectively. -
minloglevel (int, default=0, which -is INFO) -
Log messages at or above this level. Again, the numbers of -severity levels INFO, WARNING, -ERROR, and FATAL are 0, 1, 2, and 3, -respectively. -
log_dir (string, default="") -
If specified, logfiles are written into this directory instead -of the default logging directory. -
v (int, default=0) -
Show all VLOG(m) messages for m less or -equal the value of this flag. Overridable by --vmodule. -See the section about verbose logging for more -detail. -
vmodule (string, default="") -
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., gfs* 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 the section about verbose logging. -
- -

There are some other flags defined in logging.cc. Please grep the -source code for "DEFINE_" to see a complete list of all flags. - -

You can also modify flag values in your program by modifying global -variables FLAGS_* . Most settings start working -immediately after you update FLAGS_* . The exceptions are -the flags related to destination files. For example, you might want to -set FLAGS_log_dir before -calling google::InitGoogleLogging . Here is an example: - -

-   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";
-
- -

Conditional / Occasional Logging

- -

Sometimes, you may only want to log a message under certain -conditions. You can use the following macros to perform conditional -logging: - -

-   LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-
- -The "Got lots of cookies" message is logged only when the variable -num_cookies 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. - -
-   LOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
-
- -

The above line outputs a log messages 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 combine conditional and occasional logging with the -following macro. - -

-   LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << google::COUNTER
-                                           << "th big cookie";
-
- -

Instead of outputting a message every nth time, you can also limit -the output to the first n occurrences: - -

-   LOG_FIRST_N(INFO, 20) << "Got the " << google::COUNTER << "th cookie";
-
- -

Outputs log messages for the first 20 times it is executed. Again, -the google::COUNTER identifier indicates which repetition is -happening. - -

Debug Mode Support

- -

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. - -

-   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";
-
- -

CHECK Macros

- -

It is a good practice to check expected conditions in your program -frequently to detect errors as early as possible. The -CHECK macro provides the ability to abort the application -when a condition is not met, similar to the assert macro -defined in the standard C library. - -

CHECK aborts the application if a condition is not -true. Unlike assert, it is *not* controlled by -NDEBUG, so the check will be executed regardless of -compilation mode. Therefore, fp->Write(x) in the -following example is always executed: - -

-   CHECK(fp->Write(x) == 4) << "Write failed!";
-
- -

There are various helper macros for -equality/inequality checks - CHECK_EQ, -CHECK_NE, CHECK_LE, CHECK_LT, -CHECK_GE, and CHECK_GT. -They compare two values, and log a -FATAL message including the two values when the result is -not as expected. The values must have operator<<(ostream, -...) defined. - -

You may append to the error message like so: - -

-   CHECK_NE(1, 2) << ": The world must be ending!";
-
- -

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: - -

-   CHECK_EQ(string("abc")[1], 'b');
-
- -

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. - -

-   CHECK_EQ(some_ptr, static_cast<SomeType*>(NULL));
-
- -

Better yet, use the CHECK_NOTNULL macro: - -

-   CHECK_NOTNULL(some_ptr);
-   some_ptr->DoSomething();
-
- -

Since this macro returns the given pointer, this is very useful in -constructor initializer lists. - -

-   struct S {
-     S(Something* ptr) : ptr_(CHECK_NOTNULL(ptr)) {}
-     Something* ptr_;
-   };
-
- -

Note that you cannot use this macro as a C++ stream due to this -feature. Please use CHECK_EQ described above to log a -custom message before aborting the application. - -

If you are comparing C strings (char *), a handy set of macros -performs case sensitive as well as case insensitive comparisons - -CHECK_STREQ, CHECK_STRNE, -CHECK_STRCASEEQ, and CHECK_STRCASENE. The -CASE versions are case-insensitive. You can safely pass NULL -pointers for this macro. They treat NULL and any -non-NULL string as not equal. Two NULLs are -equal. - -

Note that both arguments may be temporary strings which are -destructed at the end of the current "full expression" -(e.g., CHECK_STREQ(Foo().c_str(), Bar().c_str()) where -Foo and Bar return C++'s -std::string). - -

The CHECK_DOUBLE_EQ macro checks the equality of two -floating point values, accepting a small error margin. -CHECK_NEAR accepts a third floating point argument, which -specifies the acceptable error margin. - -

Verbose Logging

- -

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 -VLOG macro, which allows you to define your own numeric -logging levels. The --v command line option controls -which verbose messages are logged: - -

-   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";
-
- -

With VLOG, the lower the verbose level, the more -likely messages are to be logged. For example, if ---v==1, VLOG(1) will log, but -VLOG(2) will not log. This is opposite of the severity -level, where INFO is 0, and ERROR is 2. ---minloglevel of 1 will log WARNING and -above. Though you can specify any integers for both VLOG -macro and --v flag, the common values for them are small -positive integers. For example, if you write VLOG(0), -you should specify --v=-1 or lower to silence it. This -is less useful since we may not want verbose logs by default in most -cases. The VLOG macros always log at the -INFO log level (when they log at all). - -

Verbose logging can be controlled from the command line on a -per-module basis: - -

-   --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
-
- -

will: - -

    -
  • a. Print VLOG(2) and lower messages from mapreduce.{h,cc} -
  • b. Print VLOG(1) and lower messages from file.{h,cc} -
  • c. Print VLOG(3) and lower messages from files prefixed with "gfs" -
  • d. Print VLOG(0) and lower messages from elsewhere -
- -

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 command line flags. - -

There's also VLOG_IS_ON(n) "verbose level" condition -macro. This macro returns true when the --v is equal or -greater than n. To be used as - -

-   if (VLOG_IS_ON(2)) {
-     // do some logging preparation and logging
-     // that can't be accomplished with just VLOG(2) << ...;
-   }
-
- -

Verbose level condition macros VLOG_IF, -VLOG_EVERY_N and VLOG_IF_EVERY_N behave -analogous to LOG_IF, LOG_EVERY_N, -LOF_IF_EVERY, but accept a numeric verbosity level as -opposed to a severity level. - -

-   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;
-
- -

Failure Signal Handler

- -

-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. - -

-*** 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)
-
- -

-By default, the signal handler writes the failure dump to the standard -error. You can customize the destination by InstallFailureWriter(). - -

Miscellaneous Notes

- -

Performance of Messages

- -

The conditional logging macros provided by glog (e.g., -CHECK, LOG_IF, VLOG, ...) 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. - -

-   CHECK(obj.ok) << obj.CreatePrettyFormattedStringButVerySlow();
-
- -

User-defined Failure Function

- -

FATAL severity level messages or unsatisfied -CHECK condition terminate your program. You can change -the behavior of the termination by -InstallFailureFunction. - -

-   void YourFailureFunction() {
-     // Reports something...
-     exit(1);
-   }
-
-   int main(int argc, char* argv[]) {
-     google::InstallFailureFunction(&YourFailureFunction);
-   }
-
- -

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). - -

Raw Logging

- -

The header file <glog/raw_logging.h> 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 src/glog/raw_logging.h.in for detail. -

- -

Google Style perror()

- -

PLOG() and PLOG_IF() and -PCHECK() behave exactly like their LOG* and -CHECK equivalents with the addition that they append a -description of the current state of errno to their output lines. -E.g. - -

-   PCHECK(write(1, NULL, 2) >= 0) << "Write NULL failed";
-
- -

This check fails with the following error message. - -

-   F0825 185142 test.cc:22] Check failed: write(1, NULL, 2) >= 0 Write NULL failed: Bad address [14]
-
- -

Syslog

- -

SYSLOG, SYSLOG_IF, and -SYSLOG_EVERY_N 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. - -

Strip Logging Messages

- -

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: - -

If your application has code like this: - -

-   #define GOOGLE_STRIP_LOG 1    // this must go before the #include!
-   #include <glog/logging.h>
-
- -

The compiler will remove the log messages whose severities are less -than the specified integer value. Since -VLOG logs at the severity level INFO -(numeric value 0), -setting GOOGLE_STRIP_LOG to 1 or greater removes -all log messages associated with VLOGs as well as -INFO log statements. - -

Automatically Remove Old Logs

- -

To enable the log cleaner: - -

-google::EnableLogCleaner(3); // keep your logs for 3 days
-
- -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. - -

This feature can be disabled at any time (if it has been enabled) - -

-google::DisableLogCleaner();

Notes for Windows users

- -

Google glog defines a severity level ERROR, which is -also defined in windows.h . You can make glog not define -INFO, WARNING, ERROR, -and FATAL by defining -GLOG_NO_ABBREVIATED_SEVERITIES before -including glog/logging.h . Even with this macro, you can -still use the iostream like logging facilities: - -

-  #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";
-
- -

-However, you cannot -use INFO, WARNING, ERROR, -and FATAL anymore for functions defined -in glog/logging.h . - -

-  #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);
-
- -

-If you don't need ERROR defined -by windows.h, there are a couple of more workarounds -which sometimes don't work: - -

    -
  • #define WIN32_LEAN_AND_MEAN or NOGDI - before you #include windows.h . -
  • #undef ERROR after you #include - windows.h . -
- -

See -this issue for more detail. - -

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.
