A bit more information. This is particular to the access log (Z2.log). When z2.py starts the access log, it successfully saves the file_logger instance to sys.__lg: lg = logger.file_logger(LOG_PATH) zLOG.LOG('z2', zLOG.BLATHER, 'Using access log file %s' % LOG_PATH) sys.__lg = lg However, when Signals.py handles SIGUSR2 and tries to recover the file_logger instance with "getattr(sys, '__lg', None)" it can't find it and silently fails. I can't find this in the collector, which makes me think the platform might be platform-specific. Is anyone successfully using SIGUSR2 to rotate Z2.log? Steve McMahon wrote:

I've been trying to figure out how to use SIGUSR2 for log rotation with Zope 2.6.1, and am having no luck. The transcript below shows a sample attempt to move Z2.log, create a new one, then use SIGUSR2 to get Zope to reopen the log, hopefully with the new file. My event log indicates that Zope's received the signal and it claims to have reopened the logs, but the old, moved log is still being updated.

Note that using SIGHUP works. All this is happening on Zope 2.6.1, FreeBSD 4.5, Python 2.1.3. Any ideas?

/var/db/zope261/var #mv Z2.log Z2.log.rotate /var/db/zope261/var #touch Z2.log; chmod 664 Z2.log /var/db/zope261/var #kill -USR2 `cat Z2.pid` /var/db/zope261/var #tail event.log ------ 2003-02-24T08:47:20 INFO(0) Z2 Caught signal SIGUSR2 ------ 2003-02-24T08:47:20 INFO(0) Z2 Reopening log files ------ 2003-02-24T08:47:20 INFO(0) Z2 Log files reopened successfully

[Zope activity] /var/db/zope261/var #ls -l Z2.log -rw-rw-r-- 1 zope 0 Feb 24 08:46 Z2.log [note: old log file is still being updated.]

[now try SIGHUP, which works] /var/db/zope261/var #kill -HUP `cat *.pid` [Zope activity] /var/db/zope261/var #ls -l Z2.log -rw-rw-r-- 1 zope 1545 Feb 24 08:48 Z2.log
