Bug #10744 Updated: session_start() "serializes" exec

ID: 10744 Updated by: derick Reported By: fperillo@katamail.com Old-Status: Open Status: Closed Bug Type: *Session related Operating system: PHP Version: 4.0.4pl1 Assigned To: Comments: That is by design (for file based session storage at least). See http://www.php.net/bugs.php?id=6287&edit=1 and http://bugs.php.net/?id=10675&edit=1 All access to session variables in PHP4 is serialized. If you want to start some daemon from inside your php script make it to close all unused file handles at startup or close the session before exec(). oleg Previous Comments: --------------------------------------------------------------------------- [2001-05-09 04:39:31] fperillo@katamail.com Try this in a script: <?php exec( "/bin/sleep 30 >/dev/null 2>&1 </dev/null &" ) ; echo "Done !!" ; ?> Now call it from the browser several time (Reload button). If you type a ps ax command you will see several "sleep 30" processes. Wait all the processes to stop. Now put session_start() as the first line. Press RELOAD: it completes OK. Now press RELOAD again: it hangs !!! It waits for the sleep to terminate before starting the next !! So if you press RELOAD 10 times you need to wait 300 seconds !! Is it a normal behaviour ? How can I have a process completely in the background ? Francesco PS: I tried to put the nohup in the exec string with no success --------------------------------------------------------------------------- ATTENTION! Do NOT reply to this email!
