#33349 [NEW]: imap_fetchstructure hangs on some mails

From: benjamin dot malynovytch at libertic dot fr Operating system: Linux (Mandrake 9.2) PHP version: 5.0.4 PHP Bug Type: IMAP related Bug description: imap_fetchstructure hangs on some mails Description: ------------ Calling imap_fetchstructure() on certain multi-part messages causes an indefinite hang (function never returns). Versions: Tried: PHP-5.0.3, PHP-5.0.4, PHP-5.0.5-dev c-client: imap-2004d Apache: httpd-2.0.53 I gave a look at other related bugs, and checkd that que imap link was still up when the function was called. I also tried to place a timer between two function calls. Nothing worked, the link is still up when que function hangs. Reproduce code: --------------- <?php $pop_user = "someuser"; $pop_pass = "somepassword"; $pop_host = "somehost.somewhere.com"; $mbox_path = "/path/to/failedmsg.1"; $pop_conn_string = "\{$pop_host:143/imap}$mbox_path"; $pop_conn = imap_open($pop_conn_string, $pop_user, $pop_pass); // Assuming message-of-death is first one in the mbox $mimeobj = imap_fetchstructure($pop_conn, 1); // Never gets here... imap_close($pop_conn); ?> Expected result: ---------------- imap_fetchstructure() should quickly return the structure of the message. Actual result: -------------- The function never returns on most mails, and page loading stops. -- Edit bug report at http://bugs.php.net/?id=33349&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33349&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33349&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33349&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33349&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33349&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33349&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33349&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33349&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33349&r=support Expected behavior: http://bugs.php.net/fix.php?id=33349&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33349&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33349&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33349&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33349&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33349&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33349&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33349&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33349&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33349&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33349&r=mysqlcfg
