#32301 [NEW]: PHP hangs during decompression

From: ralph at cs dot cf dot ac dot uk Operating system: MacOS X 10.3.x PHP version: 5.0.3 PHP Bug Type: *Compression related Bug description: PHP hangs during decompression Description: ------------ Running the following compression / decompression code on MacOS X results in php hanging, and control never being retuyrned to the user. One particular side effect is that doing sudo pear upgrade-all does not install the upgrades and hangs. However, this problem appears to be in php itself, not pear. Reproduce code: --------------- <?php $fd = gzopen('temp.gz', 'wb9'); for ($i=0; $i<5000; $i++) gzwrite($fd, "hello world !"); gzclose($fd); $fd = gzopen('temp.gz', 'rb'); while (strlen($v_binary_data = gzread($fd, 512)) != 0) { } gzclose($fd); echo "OK Done !"; ?> Expected result: ---------------- OK Done! on completion. Actual result: -------------- Never returns. -- Edit bug report at http://bugs.php.net/?id=32301&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32301&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32301&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32301&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32301&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32301&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32301&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32301&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32301&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32301&r=support Expected behavior: http://bugs.php.net/fix.php?id=32301&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32301&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32301&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32301&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32301&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32301&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32301&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32301&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32301&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32301&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32301&r=mysqlcfg
