Why would you want to allow opening same mailbox by two simultaneous processes? Previous Comments: ------------------------------------------------------------------------ [2006-01-05 04:13:45] jik at kamens dot brookline dot ma dot us Please look carefully at the output. The notices are not "harmless". Note that the message "successfully opened mailbox" only appears *once*. It should appear twice, because there are two processes who both want to open the mailbox. It only appears once because one of the two processes is killed by a USR2 signal as I've described. I don't know why the patch I sent didn't help for you. It reliably solves the problem for me. Perhaps I picked bad preprocessor symbols and it's not actually getting compiled into the object code on your system. Can you put debugging code in to see if the arm_signal calls are actually happening? Thanks. ------------------------------------------------------------------------ [2006-01-05 01:01:06] [EMAIL PROTECTED] I get the same notices, which seem quite harmless anyway. And your patch did not make any difference whatsoever. ------------------------------------------------------------------------ [2006-01-04 21:53:23] jik at kamens dot brookline dot ma dot us libc-client-2002e-18.1 RPM from Fedora Core. I checked the current c-client sources from washington.edu and they seem susceptible to this problem as well, judging from an examination of the source code. The USR2 functionality has been in c-client since 1993, as far as I can tell. ------------------------------------------------------------------------ [2006-01-04 21:49:48] [EMAIL PROTECTED] Exactly what c-client version you linked PHP with? And how was it compiled? ------------------------------------------------------------------------ [2006-01-04 21:14:14] jik at kamens dot brookline dot ma dot us There's a patch which makes this problem go away at http://stuff.mit.edu/~jik/php-5.1.1-imap-usr2.patch.txt. However, rather than using the #if statement I used to figure out whether to enable the relevant code, you may want to insert a check for the function arm_signal in the c-client library in the configure script, define a cpp symbol if the function exists, and use my code if that cpp symbol is defined. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
