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 only 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. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. 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. + +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=c89 CFLAGS=-O2 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 must use a version of `make' that +supports the `VPATH' variable, such as 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 `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have 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' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' 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 `--target=TYPE' option 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 + +will cause the specified gcc to be used as the C compiler (unless it is +overridden in the site shell script). + +`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. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..0111d0f --- /dev/null +++ b/Makefile.am @@ -0,0 +1,172 @@ +## Process this file with automake to produce Makefile.in + +# Make sure that when we re-make ./configure, we get the macros we need +ACLOCAL_AMFLAGS = -I m4 + +# This is so we can #include +AM_CPPFLAGS = -I$(top_srcdir)/src + +# This is mostly based on configure options +AM_CXXFLAGS = + +# These are good warnings to turn on by default +if GCC +AM_CXXFLAGS += -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare +endif + +# These are x86-specific, having to do with frame-pointers +if X86_64 +if ENABLE_FRAME_POINTERS +AM_CXXFLAGS += -fno-omit-frame-pointer +else + # TODO(csilvers): check if -fomit-frame-pointer might be in $(CXXFLAGS), + # before setting this. +AM_CXXFLAGS += -DNO_FRAME_POINTER +endif +endif + +glogincludedir = $(includedir)/glog +## The .h files you want to install (that is, .h files that people +## who install this package can include in their own applications.) +gloginclude_HEADERS = src/glog/log_severity.h src/glog/logging.h src/glog/raw_logging.h src/glog/vlog_is_on.h src/glog/stl_logging.h + +docdir = $(prefix)/share/doc/$(PACKAGE)-$(VERSION) +## This is for HTML and other documentation you want to install. +## Add your documentation files (in doc/) in addition to these +## top-level boilerplate files.

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 <google/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/google 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 influences 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. + +

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 " << COUNTER << "th cookie";
+
+ +

The above line outputs a log messages on the 1st, 11th, +21st, ... times it is executed. Note that the special +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 " << 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 " << COUNTER << "th cookie";
+
+ +

Outputs log messages for the first 20 times it is executed. Again, +the 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 " << COUNTER << "th cookie";
+
+ +

All "debug mode" logging is compiled away to nothing for non-debug mode +compiles. + +

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(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 returns 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 " << 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 " << COUNTER;
+
+ +

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 <google/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/google/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 <google/logging.h>
+
+ +

The compiler will remove the log messages whose severity 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. + +
