From: wharmby at uk dot ibm dot com Operating system: Windows XP PHP version: 6CVS-2009-01-21 (snap) PHP Bug Type: Zlib Related Bug description: gzuncompress does not report expcted error Description: ------------ gzuncompress() does not report error if $limit > 0 but too short for data being uncompressed. Problem is PHP specific; test OK on latest php 5.2 and 5.3 snaps. I will be dropping new PHPT shortly for gzuncompress(); the PHP 6 tests will be tagged with a XFAIL because of this defect. Reproduce code: --------------- <?php $data = b'string_val'; $compressed = gzcompress($data); var_dump(gzuncompress($compressed, strlen($data))); var_dump(gzuncompress($compressed, 1)); ?> Expected result: ---------------- Expected output (based on output for same script when run on 5.2/5.3) string(10) "string_val" Warning: gzuncompress(): buffer error in <...> on line 5 bool(false) Actual result: -------------- string(10) "string_val" string(10) "string_val" -- Edit bug report at http://bugs.php.net/?id=47179&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47179&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47179&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47179&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47179&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47179&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47179&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47179&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47179&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47179&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47179&r=support Expected behavior: http://bugs.php.net/fix.php?id=47179&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47179&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47179&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47179&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47179&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47179&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47179&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47179&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47179&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47179&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47179&r=mysqlcfg
