#29100 [NEW]: fread ignores memory_limit

From: pickleman78 at sbcglobal dot net Operating system: WIndows XP PHP version: 4.3.6 PHP Bug Type: Reproducible crash Bug description: fread ignores memory_limit Description: ------------ I am getting a crash from PHP when I mistakenly attempt to read 1,761,607,681 bytes from an incoming socket. Now I would reasonably assume that since this is far above the memory limit set in my PHP.ini file memory_limit = 8M I would expect it to stop before even attempting to allocate such a rediculous ammount of memory for the script. In this case it fails with a FATAL: emalloc() unable to allocate 1761607681 bytes. Should this be what it does? I would expect it to issue an ERROR as opposed to crashing. Reproduce code: --------------- <?php $fp=fsockopen("http://php.net"); $data=fread($fp,1761607681); ?> Expected result: ---------------- It would be expected to receive an error as opposed to PHP trying to allocate this memory Actual result: -------------- Stated above, causes FATAL: emalloc() could not...... -- Edit bug report at http://bugs.php.net/?id=29100&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=29100&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=29100&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=29100&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=29100&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=29100&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=29100&r=needscript Try newer version: http://bugs.php.net/fix.php?id=29100&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=29100&r=support Expected behavior: http://bugs.php.net/fix.php?id=29100&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=29100&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=29100&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=29100&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=29100&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=29100&r=dst IIS Stability: http://bugs.php.net/fix.php?id=29100&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=29100&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=29100&r=float
