#49411 [NEW]: zlib.inflate Stream Filter Broken

From: alex at malexmedia dot net Operating system: Linux PHP version: 5.2.10 PHP Bug Type: Zlib Related Bug description: zlib.inflate Stream Filter Broken Description: ------------ The ZLib "inflate" stream filter appears to be broken in PHP 5.2.9 and 5.2.10. When trying to inflate a GZip file, or even a stream previously compressed with zlib.deflate, zlib.inflate returns no output. Reproduce code: --------------- <?php //zlibtest.php //Usage: // $ echo TEST TEST TEST | gzip | php zlibtest.php $input = fopen("php://stdin", "rb"); stream_filter_append($input, 'zlib.inflate', STREAM_FILTER_READ); while(!feof($input) && ($buffer = fread($input, 8192)) !== FALSE) fwrite(STDOUT, $buffer); fclose($input); //Inexplicably, this will produce no output on STDOUT. //Even the example at http://us3.php.net/filters.compression behaves incorrectly. ?> Expected result: ---------------- I expect to see "TEST TEST TEST" on the command line. Actual result: -------------- The zlib.inflate filter is clearly not producing decompressed results on fread() operations. By my reckoning, this is a problem. -- Edit bug report at http://bugs.php.net/?id=49411&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49411&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49411&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49411&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49411&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49411&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49411&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49411&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49411&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49411&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49411&r=support Expected behavior: http://bugs.php.net/fix.php?id=49411&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49411&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49411&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49411&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49411&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49411&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49411&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49411&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49411&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49411&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49411&r=mysqlcfg
