#36526 [NEW]: compressed data corruption when passed to another script via _REQUEST

From: terry at kryogenic dot co dot uk Operating system: Debian PHP version: 5.1.2 PHP Bug Type: *Compression related Bug description: compressed data corruption when passed to another script via _REQUEST Description: ------------ serializing, compressing and bzcompress/gzcompress an object then sending to another script via _REQUEST seems to cause corruption. bzdecompress returns error code -4. This following code works in php4 & php5.0.x but not 5.1.2. gzcompress also returns a very similar error. Reproduce code: --------------- script a) $compStr = bzcompress(serialize($an_array)); $base64Str = base64_encode($compStr); /* send this to script b like so: * http://somehost/script_b.php?object=$base64Str */ script b) $decStr = bzdecompress(base64_decode($_REQUEST['error'])); $array = unserialize($decStr); Expected result: ---------------- bzdecompress should succeed and after unserialization I should end up with the original array from script a. Actual result: -------------- bzdecompress returns -4 (data error) and unserialize would of course fail in the code above. -- Edit bug report at http://bugs.php.net/?id=36526&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36526&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36526&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36526&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36526&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36526&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36526&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36526&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36526&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36526&r=support Expected behavior: http://bugs.php.net/fix.php?id=36526&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36526&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36526&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36526&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36526&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36526&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36526&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36526&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36526&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36526&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36526&r=mysqlcfg
