#48725 [NEW]: Support for flushing in zlib stream(?)

From: slusarz at curecanti dot org Operating system: Linux PHP version: 5.2.10 PHP Bug Type: Streams related Bug description: Support for flushing in zlib stream(?) Description: ------------ There does not seem to be any support for flushing data in a zlib compression stream. Not sure if this is an omission, something obvious that I am missing (and may not be in the documentation), or the fact that the zlib stream filter does not support socket operation. Reproduce code: --------------- $stream = stream_socket_client([...]); // Login to remote server & enable compression remotely (e.g. implementation of IMAP COMPRESS extension - RFC 4978) stream_filter_append($stream, 'zlib.deflate', STREAM_FILTER_WRITE); stream_set_write_buffer($stream, 0); fwrite($stream, 'Testing'); fflush($stream); // tcpdump confirms that nothing is sent from the PHP server to the remote server. Can confirm that upon socket timeout, the pending data is sent. // Similarly, compressed data from incoming stream is not available either. stream_filter_append($stream, 'zlib.inflate', STREAM_FILTER_READ); $in = fread($stream, 8192); // fread() on $stream will timeout. -- Edit bug report at http://bugs.php.net/?id=48725&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48725&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48725&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48725&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48725&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48725&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48725&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48725&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48725&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48725&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48725&r=support Expected behavior: http://bugs.php.net/fix.php?id=48725&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48725&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48725&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48725&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48725&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48725&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48725&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48725&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48725&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48725&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48725&r=mysqlcfg
