#33623 [NEW]: History buffer in gzinflate

From: vincent dot lascaux at centraliens dot net Operating system: PHP version: 5.0.4 PHP Bug Type: Feature/Change Request Bug description: History buffer in gzinflate Description: ------------ Hi, I'm the autor of File_Archive (http://pear.php.net/package/File_Archive) and I'm adding a CAB file reader to it. This format can store deflated data, that can be uncompressed with gzinflate. Unfortunately, the data is cut blocks. The doc specifies that "Each block is flushed out of the compressor before the next block begins, so the last sub-block in each block will be marked as the ‘end’ of the stream. Any decoding trees are discarded after each block, with only the history buffer surviving from one block to the next." My feature request is to be able to give to gzinflate the history buffer to use, and to retrieve from it the history buffer after the compression of the data. A possible syntax would be string gzinflate(string data[, int length[, array options]]) The array could store a reference to a history buffer that would be used (if not null) to uncompress the data and that would be updated after the data has been uncompressed. -- Edit bug report at http://bugs.php.net/?id=33623&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33623&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33623&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33623&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33623&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33623&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33623&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33623&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33623&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33623&r=support Expected behavior: http://bugs.php.net/fix.php?id=33623&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33623&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33623&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33623&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33623&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33623&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33623&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33623&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33623&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33623&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33623&r=mysqlcfg
