#27423 [Opn->Bgs]: Session hang

ID: 27423 Updated by: irchtml@php.net Reported By: ypout at mail dot ru -Status: Open +Status: Bogus Bug Type: Session related Operating System: Linux 2.4.25 PHP Version: 4.3.4 New Comment: The problem is that the session files are locked to prevent concurrent writes so other requests for the same session while the provided code is still executing will not allow access. session_write_close() will write the session data and release the lock on the file, allowing subsequent requests access to it. There's a little more info on the session_write_close manual page (http://php.net/session_write_close). Status -> Bogus Previous Comments: ------------------------------------------------------------------------ [2004-02-27 23:46:54] irchtml@php.net Try a call to session_write_close() before the system()/popen() call. ------------------------------------------------------------------------ [2004-02-27 10:35:54] ypout at mail dot ru Description: ------------ PHP sessions will hang if an external command is executed either through system() or the popen() calls. The session restores as soon as the external command terminates. The problem is when I try to follow another link in a multiframed view. Reproduce code: --------------- session_start(); ..... ..... set_time_limit(0); ignore_user_abort(TRUE); system($cmd, $sys_res); // Takes very long ..... note (I tried popen aswell) Expected result: ---------------- does not matter Actual result: -------------- does not matter ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27423&edit=1
