From: Operating system: RHEL/CentOS PHP version: 5.3.6 Package: Session related Bug Type: Bug Bug description:Unable to open sessions while MySQL DB connection is open
Description: ------------ On RHEL(or Centos) 5.6 running any available PHP package thru RedHat and the latest version of PHP (5.3.6). Run first script provided in a browser, then while that is running, fire up the second script. The second script will not finish until the first one calls the session_write_close() function. Test script: --------------- === 1.php === <?php $counter=1; $DB= mysql_connect(localhost,$user,$pass,true); mysql_select_db("database"); session_start(); echo "Starting...\n"; while ( $counter <= 5 ) { echo "$counter ... \n"; sleep(2); $counter++; } echo "Done!... \n"; session_write_close(); ?> === 2.php === <?php session_start(); echo "TESTING!\n"; session_write_close(); ?> Expected result: ---------------- When both scripts are run at the same time, the second script should exit (nearly) immediately after opening a session, echoing the TESTING line, then closing the session. After the while loop is done in the first script, it should exit as expected. Actual result: -------------- When the both scripts are executed at the same time (or one right after the other), the second script hangs at the 'session_start()' line until the first script is done. -- Edit bug report at https://bugs.php.net/bug.php?id=55151&edit=1 -- Try a snapshot (PHP 5.2): https://bugs.php.net/fix.php?id=55151&r=trysnapshot52 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55151&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55151&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55151&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55151&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55151&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55151&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55151&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55151&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55151&r=support Expected behavior: https://bugs.php.net/fix.php?id=55151&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55151&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55151&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55151&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55151&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55151&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55151&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55151&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55151&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55151&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55151&r=mysqlcfg Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55151&r=trysnapshot54
