Hi All,
Link:
http://stackoverflow.com/questions/34037325/problems-with-file-rotation-after-adding-append-flag-in-boost-1-59-log-v2
After adding append flag "keywords::open_mode = std::ios_base::app" to file
sink the normal file rotation is not happening when the file reaches Max size,
as specified in below code:
typedef sinks::synchronous_sink< sinks::text_file_backend > file_sink;
boost::shared_ptr< logging::core > core = logging::core::get();
boost::shared_ptr< file_sink > sink(new file_sink(
keywords::file_name = "test.log",
keywords::open_mode = std::ios_base::app,
keywords::rotation_size = 5000000
));
sink->locked_backend()->set_file_collector(sinks::file::make_collector(
keywords::target = "tmp",
keywords::max_size = 10000,
keywords::min_free_space = 1000
));
sink->locked_backend()->scan_for_files();
sink->locked_backend()->auto_flush(true);
core->add_sink(sink);
Boost Log version: 1.59
Behavior observed: After every time the process using boost logger starts; the
log messages are getting appended to existing log file instead of creating new
log file. But when the log file reaches it max size then boost file rotation
policy is not happening and new log file is getting created without moving old
log file to target directory.
Expected behavior: The log file should be appended with log messages and when
reaches max size it should be rotated properly.
Any help.
Thanks in advance,
arun.
