Description Charles Dennett 2014-04-22 13:14:49 UTC 
Description of problem:  Rotation via logrotate of boinc log files fails to restart boinc-client in order to pick up new log file.  Logging continues to old log file.


Version-Release number of selected component (if applicable):  boinc-client-7.2.42-1.gitdd0d630.fc20.x86_64 although problem also existed in previous verions.


How reproducible:  Always happens


Steps to Reproduce:
1.Run boinc-client for a while to allow log records to appear in /var/log/boinc.log
2.Run logrotate

Actual results:  Note that after running logrotate original log file is now named /var/log/boinc.log-<DATE>. New empty log file created as /var/log/boinc.log.  Logging continues to /var/log/boinc.log-<DATE>.  Similar for /var/log/boincerr.log


Expected results: After rotation writing should stop to rotated log file and start in new log file.


Additional info:  /etc/logrotate.d/boinc-client performs rotation of log files.  It also looks for the file /var/lib/boinc/lockfile to determine if boinc-client is running and if so, it restarts boinc-client so it can close rotated log files and start writing to new log files.  Such a lockfile does not exist.  Cannot find any such related lockfile anywhere.  Unknown if the boinc-client process is supposed to create it or if it should be created by /usr/lib/systemd/system/boinc-client.service.
Comment 1 Charles Dennett 2014-04-22 17:25:40 UTC 
Discovered that the use of the option --allow_multiple_clients in /usr/bin/boinc causes boinc-client not to create the lockfile.  boinc-client seems to run ok without it.  Is it really needed/
Comment 2 Charles Dennett 2015-01-19 12:12:45 UTC 
Problem continues to exist in Fedora 21
Comment 3 Charles Dennett 2015-07-07 23:20:02 UTC 
Problem continues to exist if Fedora 22

Still in my FC21 too

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Comment 7 DaveG 2016-01-29 13:16:50 UTC 
The BOINC client does not have a facility to close/reopen it's log files.

The current log rotation script attempts to re-start the service but relies on initscripts service lock files that are not created by the systemd unit.

The result is that there is no effective log rotation.

Re-starting the BOINC client can cause problems with some projects and risks losing results in long-running models.

The fall-back solution (that I have used for a few months now) is to rotate the log files with copy/truncate and allow the client to keep running. The log files are simply the redirected standard error and output of the process.

There is a *small* risk of losing log output during the copy/truncate but I consider that preferable to uncontrolled file growth.

My working log rotation script is attached.
