#37574 [NEW]: Add warning about session on the documentation page for Program Execution

From: dr at sweety dot li Operating system: Win NT PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Add warning about session on the documentation page for Program Execution Description: ------------ I'm referring to the "bug" descriped here : http://bugs.php.net/bug.php?id=10675&edit=1 . I would recommend that you add a warning on the "Program Execution Functions" documentation page which basically advises the programmer to close any open session before calling exec() or other related functions as otherwise the PHP script may hang! Reproduce code: --------------- session_start(); exec('ls'); // Save this, open the page in a browser and reload repeatedly. After several successful reloads, the page will just hang Expected result: ---------------- nothing, the correct code seems to be: session_start(); /* .... code ... */ session_write_close(); exec('ls'); @session_start(); // There's no locking in this code -- Edit bug report at http://bugs.php.net/?id=37574&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37574&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37574&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37574&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37574&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37574&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37574&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37574&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37574&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37574&r=support Expected behavior: http://bugs.php.net/fix.php?id=37574&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37574&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37574&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37574&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37574&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37574&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37574&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37574&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37574&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37574&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37574&r=mysqlcfg
