#32199 [Fbk->Opn]: php-cgi hanging

ID: 32199 User updated by: valenok at gmail dot com Reported By: valenok at gmail dot com -Status: Feedback +Status: Open Bug Type: CGI related Operating System: windows xp professional -PHP Version: 5CVS-2005-03-05 +PHP Version: 5.0.3 New Comment: The reason I am reporting is I am writing HTTP server. I have found that php pages sometimes do not 'return': browser shows the output, but spinner still spins, and php process is still running. It never happens with other CGIs - perl, python, native executables. I never happened on unix. So first thing I blamed was my server. But. I have found that it hangs directly from command line, also I have found other people reports about this kind of issue (hanging on IIS, Xitami, etc, never on Apache). This gave me a reason to suspect php itself.

Now, it hangs every first-second time I run it. on unix (tried on freebsd) this never happens. Also, I suspect, Apache handles php right, so it does not hang. could it be the environment issue? does php manipulate with some global resource (mutex or so)? what can I do to debug it ? ------------------------------------------------------------------------ [2005-03-06 16:13:12] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip ------------------------------------------------------------------------ [2005-03-06 14:34:48] valenok at gmail dot com basically, the best way to test it is to make a simple script that runs "php-cgi.exe test.php" in an infinite loop. Eventually, it will stuck. ------------------------------------------------------------------------ [2005-03-05 15:35:46] valenok at gmail dot com Description: ------------ i wrote a simple script, test.php which does echo 'hello world'. I start cmd.exe, and run "php-cgi test.php". It returns normal HTML output, as suspected. But if I do run the same line again and again, it occasionally hangs. It shows the output, right, but hangs so only task manager can kill php-cgi process. pressing Ctrl-C, Ctrl-Z does not help. This happens if I export CGI-specific variables as well. path to php-cgi is set to global Path environment variable. Why does it happen, and why does it happen unpredictably ? Also, the same situation is with php.exe from 4.3 branch. Reproduce code: --------------- #!php-cgi <html> <? echo 'hello words!'; ?> </html> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32199&edit=1
