#40437 [NEW]: decompress.bzip2 is broken

From: phpbugger dot 5 dot n1 at spamgourmet dot com Operating system: Linux PHP version: 5.2.1 PHP Bug Type: Bzip2 Related Bug description: decompress.bzip2 is broken Description: ------------ (See example code) - when using the bzip2.decompress filter on a http://-stream, php uses a lot of CPU resources and hangs. Decompressing with bzdecompress works, however, as does using zlib.decompress filters on .gz files via HTTP. Reproduce code: --------------- <?php $url = 'http://php.net/backend/notes/all.bz2'; $url = 'http://de.archive.ubuntu.com/ubuntu/dists/edgy/restricted/binary-i386/Packages.bz2'; /* this works: */ $data = bzdecompress(file_get_contents($url)); echo "bzdecompress is finished!\n"; /* however, file_get_contents will block while PHP uses a lot of CPU time */ $fp = fopen($url,'rb'); stream_filter_append($fp, 'bzip2.decompress'); stream_get_contents($fp); echo "stream_get_contents is finished!\n" ?> -- Edit bug report at http://bugs.php.net/?id=40437&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40437&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40437&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40437&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40437&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40437&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40437&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40437&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40437&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40437&r=support Expected behavior: http://bugs.php.net/fix.php?id=40437&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40437&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40437&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40437&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40437&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40437&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40437&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40437&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40437&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40437&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40437&r=mysqlcfg
