note 86155 added to function.readfile

There's a problem with the session mutex and file handling in PHP that can cause deadlocks and php to fail @ maximum execution time. This includes any kind of exec flavour, and also readfile. We had a problem where if the user tried to download a file from our server that was sent with readfile, but then cancelled and retried straight away, php would freeze and time out. The solution was to end_session() before sending the file, this fixed it. ---- Server IP: 92.48.74.199 Probable Submitter: 80.6.91.225 ---- Manual Page -- http://www.php.net/manual/en/function.readfile.php Edit -- https://master.php.net/note/edit/86155 Del: integrated -- https://master.php.net/note/delete/86155/integrated Del: useless -- https://master.php.net/note/delete/86155/useless Del: bad code -- https://master.php.net/note/delete/86155/bad+code Del: spam -- https://master.php.net/note/delete/86155/spam Del: non-english -- https://master.php.net/note/delete/86155/non-english Del: in docs -- https://master.php.net/note/delete/86155/in+docs Del: other reasons-- https://master.php.net/note/delete/86155 Reject -- https://master.php.net/note/reject/86155 Search -- https://master.php.net/manage/user-notes.php
