[jira] [Commented] (LOG4PHP-187) Logging does not work in shutdown
function
[ https://issues.apache.org/jira/browse/LOG4PHP-187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447764#comment-13447764 ]
Ivan Habunek commented on LOG4PHP-187:
--------------------------------------
Hello Till,
I noticed this behaviour some weeks ago and fixed it. The cause of the problem was that log4php appenders were using register_shutdown_function, instead of using a destructor, in hope of exiting gracefully in case of a fatal error. Shutdown functions are executed even if a fatal error occurs, and destructors are not. However, it caused the bug you are now reporting.
Luckily, this is fixed in trunk. I have tried it out, and the ouput is:
ihabunek@vs1779:~/tmp$ cat test.log
Tue Sep 4 17:38:38 2012,715 [30453] TRACE ShutdownTest - function main() called
Tue Sep 4 17:38:39 2012,187 [30453] INFO ShutdownTest - *** start shutdown test ***
Tue Sep 4 17:38:40 2012,187 [30453] TRACE ShutdownTest - function shutdown() called
Tue Sep 4 17:38:40 2012,187 [30453] INFO ShutdownTest - *** exiting shutdown test ***
Please try for yourself and let me know if it works. To get the latest code, just run:
svn checkout https://svn.apache.org/repos/asf/logging/log4php/trunk/src/main/php log4php
Thanks for reporting.
