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.
