#42468 [Asn]: Write lock on file_get_contents fails when using a compression stream

ID: 42468 User updated by: daan at react dot nl Reported By: daan at react dot nl Status: Assigned Bug Type: Streams related Operating System: * PHP Version: 5.2CVS-2007-08-29 Assigned To: iliaa New Comment: Ah it does not say so anywhere in the streams documentation that locking is (or is not) supported - or is this tied in with one of the stream attributes as listed on http://php.net/manual/en/wrappers.compression.php ? Previous Comments: ------------------------------------------------------------------------ [2007-08-29 11:46:18] jani@php.net Ilia, this should output an error when a wrapper does not support setting options. You shouldn't try locking if a wrapper doesn't support it. ------------------------------------------------------------------------ [2007-08-29 11:03:11] daan at react dot nl Description: ------------ When using the LOCK_EX flag for the file_put_contents function, and the filename is a compression stream, no data is written. Conversely, it does work when the flag is not added, or when no compression is used. Reproduce code: --------------- <?php file_put_contents('compress.zlib://test.txt', 'blabla', LOCK_EX); var_dump(file_get_contents('compress.zlib://test.txt')); Expected result: ---------------- The string 'blabla' Actual result: -------------- An empty string ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42468&edit=1
