I previously made a minor documentation fix in
https://github.com/google/glog/pull/747. According to README, this
commit adds myself to AUTHORS and CONTRIBUTORS.
When a `-DCMAKE_INSTALL_PREFIX` is given, this could result in paths like:
/path/to/prefix//path/to/prefix/lib/cmake/glog/glog-modules.cmake
which was incorrect.
If a relative `DESTINATION` is given, it's assumed to be relative to the install prefix.
Use <chrono> and <atomic> for C++11 or greater.
For non-Windows pre-C++11 systems, use <time.h> and built-in atomic operations.
For Windows pre-C++11, use the Windows implementations for time and atomic operations.
* Add support for automatic removal of old logs
GetOverdueLogNames(string log_directory, int days) will check all
filenames under log_directory, and return a list of files whose last modified time is
over the given days (calculated using difftime()).
So that we can easily for unlink all files stored in the returned vector.
* Replaced the lines that require C++11
* embed dirent.h in project
* Add support for automatic removal of old logs
In this commit, at the end of LogFileObject::Write,
it will perform clean up for old logs.
It uses GetLoggingDirectories() and for each file in each
directory, it will check if a file is a log file produced by glog.
If it is, and it is last modified 3 days ago, then it will unlink()
this file. (It will only remove the project's own log files,
it won't remove the logs from other projects.)
Currently it is hardcoded to 3 days, I'll see if this can be
implemented in a more flexible manner.
* Implement old log cleaner
The log cleaner can be enabled and disabled at any given time.
By default, the log cleaner is disabled.
For example, this will enable the log cleaner and delete
the log files whose last modified time is >= x days
google::EnableLogCleaner(x days);
To disable it, simply call
google::DisableLogCleaner();
Please note that it will only clean up the logs produced for
its own project, the log files from other project will be untouched.
* logging: log_cleaner: Use blackslash for windows dir delim
* logging: log_cleaner: remove the range-based loops
Also replaced the hardcoded overdue days with the correct variable.
* Add Marco Wang to AUTHORS and CONTRIBUTORS
* logging: log_cleaner: Remove redundant filename stripping
Previously the full path to a file is passed into IsGlogLog(),
and then std::string::erase() is used to get the filename part.
If a directory name contains '.', then this function will be unreliable.
Now only the filename it self is passed into IsGlogLog(),
so this problem will be eradicated.
* logging: log_cleaner: improve readability
* Add google::EnableLogCleaner() to windows logging.h
* logging: log_cleaner: Remove perror message
* logging: IsGlogLog: match filename keyword by keyword
Splitting a filename into tokens by '.' causes problems
if the executable's filename contains a dot.
Filename should be matched keyword by keyword in the following
order:
1. program name
2. hostname
3. username
4. "log"
