Bug #14056 Updated: Large amounts of fileuploads in a page cause segmentation fault

ID: 14056 Updated by: sniper Reported By: michiel@tincan.co.uk Status: Closed Bug Type: Reproducible crash Operating System: Redhat 7.0 PHP Version: 4.0.6 New Comment: The next release, 4.1.0 should work just fine. ( you can try the RC2 from http://www.php.net/~zeev/php-4.1.0RC2.tar.gz) Latest CVS has new code for handling file uploads and it's under development. I'm fixing this 'no file sent' to behave same as it does in 4.1.0. --Jani Previous Comments: ------------------------------------------------------------------------ [2001-11-15 05:55:52] bate@php.net Its now Fixed. ------------------------------------------------------------------------ [2001-11-15 05:53:12] michiel@tincan.co.uk Yes, it is fixed in the current CVS, I used, php4-200111150000 I could even increase max to 300 and it worked. However, when submitting my test script with no files inserted for upload, the values of the file uploads were not "none", but a temporary file. Unexpected behaviour which may lead to problems. The size of the (temp)files is 0, but the value of the variable should be "none" or "". ------------------------------------------------------------------------ [2001-11-14 13:13:00] mfischer@php.net Cannot reproduce with current CVS. ------------------------------------------------------------------------ [2001-11-14 12:30:14] derick@php.net Can you try a snapshot from snaps.php.net and report back if that fixes the problem?
