#25037 [NEW]: SentText infinite loop

From: richard at bradders2000 dot co dot uk Operating system: Windows Server 2003 PHP version: 4.3.3RC3 PHP Bug Type: Mail related Bug description: SentText infinite loop Description: ------------ When a message is > 1024 bytes in size and therefore broken down into 1024 chunks, there is a 'goto send_chunk;' being called an infinite number of times because the conditional statement 'if ((parts * 1024) < data_cln_len)' is always true if it is ever true. This basically causes the function to just keep on sending data to the smtp server. Problem wasnt there in RC1, just RC2 and RC3. Reproduce code: --------------- int parts = (int) floor(data_cln_len / 1024); p = data_cln; for (i = 0; i < parts; i++) { strlcpy(Buffer, p, 1024); Buffer[1024] = '\0'; p += 1024; send_chunk: /* send chunk */ if ((res = Post(Buffer)) != SUCCESS) { efree(data_cln); return (res); } } if ((parts * 1024) < data_cln_len) { i = data_cln_len - (parts * 1024); strlcpy(Buffer, p, i); Buffer[i] = '\0'; goto send_chunk; } Expected result: ---------------- Data is sent in 1024 byte chunks. The remainder is then sent. Send is then terminated with '\r\n.\r\n' Actual result: -------------- Data is sent in 1024 byte chunks. The remainder is then sent...again and again and again and again. etc etc. Send is never terminated. -- Edit bug report at http://bugs.php.net/?id=25037&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25037&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25037&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25037&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25037&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25037&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25037&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25037&r=support Expected behavior: http://bugs.php.net/fix.php?id=25037&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25037&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25037&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25037&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25037&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25037&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25037&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25037&r=gnused
