Google Logging Library
======================
|Linux Github actions| |Windows Github actions| |macOS Github actions| |Total alerts| |Language grade: C++| |Codecov|
Google Logging (glog) is a C++98 library that implements application-level
logging. The library provides logging APIs based on C++-style streams and
various helper macros.
.. role:: cmake(code)
:language: cmake
.. role:: cmd(code)
:language: bash
.. role:: cpp(code)
:language: cpp
.. role:: bazel(code)
:language: starlark
Getting Started
---------------
You can log a message by simply streaming things to ``LOG``\ (<a
particular `severity level <#severity-levels>`__>), e.g.,
.. code:: cpp
#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";
}
For a detailed overview of glog features and their usage, please refer
to the `user guide <#user-guide>`__.
.. contents:: Table of Contents
Building from Source
--------------------
glog supports multiple build systems for compiling the project from
source: `Bazel <#bazel>`__, `CMake <#cmake>`__, and `vcpkg <#vcpkg>`__.
Bazel
~~~~~
To use glog within a project which uses the
`Bazel <https://bazel.build/>`__ build tool, add the following lines to
your ``WORKSPACE`` file:
.. code:: bazel
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "com_github_gflags_gflags",
sha256 = "34af2f15cf7367513b352bdcd2493ab14ce43692d2dcd9dfc499492966c64dcf",
strip_prefix = "gflags-2.2.2",
urls = ["https://github.com/gflags/gflags/archive/v2.2.2.tar.gz"],
)
http_archive(
name = "com_github_google_glog",
sha256 = "21bc744fb7f2fa701ee8db339ded7dce4f975d0d55837a97be7d46e8382dea5a",
strip_prefix = "glog-0.5.0",
urls = ["https://github.com/google/glog/archive/v0.5.0.zip"],
)
You can then add :bazel:`@com_github_google_glog//:glog` to the deps section
of a :bazel:`cc_binary` or :bazel:`cc_library` rule, and :code:`#include
<glog/logging.h>` to include it in your source code. Here’s a simple example:
.. code:: bazel
cc_binary(
name = "main",
srcs = ["main.cc"],
deps = ["@com_github_google_glog//:glog"],
)
CMake
~~~~~
glog also supports CMake that can be used to build the project on a wide
range of platforms. If you don’t have CMake installed already, you can
download it for from CMake’s `official
website <http://www.cmake.org>`__.
CMake works by generating native makefiles or build projects that can be
used in the compiler environment of your choice. You can either build
glog with CMake as a standalone project or it can be incorporated into
an existing CMake build for another project.
Building glog with CMake
^^^^^^^^^^^^^^^^^^^^^^^^
When building glog as a standalone project, on Unix-like systems with
GNU Make as build tool, the typical workflow is:
1. Get the source code and change to it. e.g., cloning with git:
.. code:: bash
git clone https://github.com/google/glog.git
cd glog
2. Run CMake to configure the build tree.
.. code:: bash
cmake -S . -B build -G "Unix Makefiles"
CMake provides different generators, and by default will pick the most
relevant one to your environment. If you need a specific version of Visual
Studio, use :cmd:`cmake . -G <generator-name>`, and see :cmd:`cmake --help`
for the available generators. Also see :cmd:`-T <toolset-name>`, which can
be used to request the native x64 toolchain with :cmd:`-T host=x64`.
3. Afterwards, generated files can be used to compile the project.
.. code:: bash
cmake --build build
4. Test the build software (optional).
.. code:: bash
cmake --build build --target test
5. Install the built files (optional).
.. code:: bash
cmake --build build --target install
Consuming glog in a CMake Project
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you have glog installed in your system, you can use the CMake command
:cmake:`find_package` to build against glog in your CMake Project as follows:
.. code:: cmake
cmake_minimum_required (VERSION 3.16)
project (myproj VERSION 1.0)
find_package (glog 0.6.0 REQUIRED)
add_executable (myapp main.cpp)
target_link_libraries (myapp glog::glog)
Compile definitions and options will be added automatically to your
target as needed.
Incorporating glog into a CMake Project
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You can also use the CMake command :cmake:`add_subdirectory` to include glog
directly from a subdirectory of your project by replacing the
:cmake:`find_package` call from the previous example by
:cmake:`add_subdirectory`. The :cmake:`glog::glog` target is in this case an
:cmake:`ALIAS` library target for the ``glog`` library target.
Again, compile definitions and options will be added automatically to
your target as needed.
vcpkg
~~~~~
You can download and install glog using the `vcpkg
<https://github.com/Microsoft/vcpkg>`__ dependency manager:
.. code:: bash
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.
User Guide
----------
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, customize the prefix attached to log messages, and more.
Following sections describe the functionality supported by glog. Please note
this description may not be complete but limited to the most useful ones. If you
want to find less common features, please check header files under `src/glog
<src/glog>`__ directory.
Severity Levels
~~~~~~~~~~~~~~~
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
<https://github.com/gflags/gflags>`__ is installed on your machine, the build
system will automatically detect and use it, allowing you to pass flags on the
command line. For example, if you want to turn the flag :cmd:`--logtostderr` on,
you can start your application with the following command line:
.. code:: bash
./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.,
.. code:: bash
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 :cmd:`--vmodule`. See `the section about
verbose logging <#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 :cmd:`--v`.
See also `the section about verbose logging <#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 :cpp:`google::InitGoogleLogging` . Here is an example:
.. code:: cpp
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:
.. code:: cpp
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.
.. code:: cpp
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.
.. code:: cpp
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:
.. code:: cpp
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.
Other times, it is desired to only log a message periodically based on a time.
So for example, to log a message every 10ms:
.. code:: cpp
LOG_EVERY_T(INFO, 0.01) << "Got a cookie";
Or every 2.35s:
.. code:: cpp
LOG_EVERY_T(INFO, 2.35) << "Got a cookie";
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.
.. code:: cpp
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:
.. code:: cpp
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 :cpp:`operator<<(ostream, ...)` defined.
You may append to the error message like so:
.. code:: cpp
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:
.. code:: cpp
CHECK_EQ(string("abc")[1], ’b’);
The compiler reports an error if one of the arguments is a pointer and the other
is :cpp:`NULL`. To work around this, simply :cpp:`static_cast` :cpp:`NULL` to
the type of the desired pointer.
.. code:: cpp
CHECK_EQ(some_ptr, static_cast<SomeType*>(NULL));
Better yet, use the ``CHECK_NOTNULL`` macro:
.. code:: cpp
CHECK_NOTNULL(some_ptr);
some_ptr->DoSomething();
Since this macro returns the given pointer, this is very useful in
constructor initializer lists.
.. code:: cpp
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 (:cpp:`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 :cpp:`NULL` pointers for this macro. They
treat :cpp:`NULL` and any non-:cpp:`NULL` string as not equal. Two :cpp:`NULL`\
s are equal.
Note that both arguments may be temporary strings which are destructed
at the end of the current "full expression" (e.g.,
:cpp:`CHECK_STREQ(Foo().c_str(), Bar().c_str())` where ``Foo`` and ``Bar``
return C++’s :cpp:`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 :cmd:`--v` command line option
controls which verbose messages are logged:
.. code:: cpp
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 :cmd:`--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. :cmd:`--minloglevel` of 1 will log ``WARNING`` and above. Though
you can specify any integers for both ``VLOG`` macro and :cmd:`--v` flag, the
common values for them are small positive integers. For example, if you write
``VLOG(0)``, you should specify :cmd:`--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:
.. code:: bash
--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 <#setting-flags>`__.
There’s also ``VLOG_IS_ON(n)`` "verbose level" condition macro. This
macro returns true when the :cmd:`--v` is equal or greater than ``n``. To
be used as
.. code:: cpp
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.
.. code:: cpp
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;
Custom Log Prefix Format
~~~~~~~~~~~~~~~~~~~~~~~~
glog supports changing the format of the prefix attached to log messages by
receiving a user-provided callback to be used to generate such strings. That
feature must be enabled at compile time by the ``WITH_CUSTOM_PREFIX`` flag.
For each log entry, the callback will be invoked with a ``LogMessageInfo``
struct containing the severity, filename, line number, thread ID, and time of
the event. It will also be given a reference to the output stream, whose
contents will be prepended to the actual message in the final log line.
For example:
.. code:: cpp
/* This function writes a prefix that matches glog's default format.
* (The third parameter can be used to receive user-supplied data, and is
* NULL by default.)
*/
void CustomPrefix(std::ostream &s, const LogMessageInfo &l, void*) {
s << l.severity[0]
<< setw(4) << 1900 + l.time.year()
<< setw(2) << 1 + l.time.month()
<< setw(2) << l.time.day()
<< ' '
<< setw(2) << l.time.hour() << ':'
<< setw(2) << l.time.min() << ':'
<< setw(2) << l.time.sec() << "."
<< setw(6) << l.time.usec()
<< ' '
<< setfill(' ') << setw(5)
<< l.thread_id << setfill('0')
<< ' '
<< l.filename << ':' << l.line_number << "]";
}
To enable the use of ``CustomPrefix()``, simply give glog a pointer to it
during initialization: ``InitGoogleLogging(argv[0], &CustomPrefix);``.
Optionally, ``InitGoogleLogging()`` takes a third argument of type ``void*``
to pass on to the callback function.
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 :cpp:`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 :cpp:`InstallFailureWriter()`.
Performance of Messages
~~~~~~~~~~~~~~~~~~~~~~~
The conditional logging macros provided by glog (e.g., ``CHECK``,
``LOG_IF``, ``VLOG``, etc.) 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.
.. code:: cpp
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 :cpp:`InstallFailureFunction`.
.. code:: cpp
void YourFailureFunction() {
// Reports something...
exit(EXIT_FAILURE);
}
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
<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.
.. code:: cpp
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:
.. code:: cpp
#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 ``VLOG``\ s as well as
``INFO`` log statements.
Automatically Remove Old Logs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To enable the log cleaner:
.. code:: cpp
google::EnableLogCleaner(3); // keep your logs for 3 days
And then 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)
.. code:: cpp
google::DisableLogCleaner();
Notes for Windows Users
~~~~~~~~~~~~~~~~~~~~~~~
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:
.. code:: cpp
#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`` .
.. code:: cpp
#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 <http://code.google.com/p/google-glog/issues/detail?id=33>`__ for
more detail.
Installation Notes for 64-bit Linux Systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The glibc built-in stack-unwinder on 64-bit systems has some problems with glog.
(In particular, if you are using :cpp:`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
:cpp:`InstallFailureSignalHandler()`, we strongly recommend you install
``libunwind`` before trying to configure or install google glog.
libunwind can be found
`here <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
:cmd:`-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 :cmd:`-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 :cpp:`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.
How to Contribute
-----------------
We’d love to accept your patches and contributions to this project.
There are a just a few small guidelines you need to follow.
Contributor License Agreement (CLA)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Contributions to any Google project must be accompanied by a Contributor
License Agreement. This is not a copyright **assignment**, it simply
gives Google permission to use and redistribute your contributions as
part of the project.
* If you are an individual writing original source code and you’re sure
you own the intellectual property, then you’ll need to sign an
`individual
CLA <https://developers.google.com/open-source/cla/individual>`__.
* If you work for a company that wants to allow you to contribute your
work, then you’ll need to sign a `corporate
CLA <https://developers.google.com/open-source/cla/corporate>`__.
You generally only need to submit a CLA once, so if you’ve already
submitted one (even if it was for a different project), you probably
don’t need to do it again.
Once your CLA is submitted (or if you already submitted one for another
Google project), make a commit adding yourself to the
`AUTHORS <./AUTHORS>`__ and `CONTRIBUTORS <./CONTRIBUTORS>`__ files. This
commit can be part of your first `pull
request <https://help.github.com/articles/creating-a-pull-request>`__.
Submitting a Patch
~~~~~~~~~~~~~~~~~~
1. It’s generally best to start by opening a new issue describing the
bug or feature you’re intending to fix. Even if you think it’s
relatively minor, it’s helpful to know what people are working on.
Mention in the initial issue that you are planning to work on that
bug or feature so that it can be assigned to you.
2. Follow the normal process of
`forking <https://help.github.com/articles/fork-a-repo>`__ the
project, and setup a new branch to work in. It’s important that each
group of changes be done in separate branches in order to ensure that
a pull request only includes the commits related to that bug or
feature.
3. Do your best to have `well-formed commit
messages <http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html>`__
for each change. This provides consistency throughout the project,
and ensures that commit messages are able to be formatted properly by
various git tools.
4. Finally, push the commits to your fork and submit a `pull
request <https://help.github.com/articles/creating-a-pull-request>`__.

// We put flags into their own namespace. It is purposefully
// named in an opaque way that people should have trouble typing

// 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.

//
// 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.

// this header to be included before apparently independent other headers.
//
// For example, base/logging.h defines various template functions to implement

// find these operator definitions via ADL.
//
// Even this solution has problems -- it may pull unintended operators into the
// namespace as well, allowing them to also be found via ADL, and creating code
// that only works with a particular order of includes. Long term, we need to
// move all of the *definitions* into namespace std, bet we need to ensure no

// 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.

// time, multiple WaitTillSent() calls (along with the one send() call) may
// be running simultaneously, we ensure thread-safety of the exchange between
// send() and WaitTillSent(), and that for each message, LOG(), send(),

//
// 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.
