Bug #52366 [Opn->Asn]: flock() fails on gzopen()'d file pointer

Edit report at http://bugs.php.net/bug.php?id=52366&edit=1 ID: 52366 Updated by: aharvey@php.net Reported by: richard at on-the dot net Summary: flock() fails on gzopen()'d file pointer -Status: Open +Status: Assigned Type: Bug -Package: Streams related +Package: Documentation problem Operating System: ubuntu PHP Version: 5.3.2 -Assigned To: +Assigned To: aharvey New Comment: flock() only works on file resources and userspace streams that implement the stream_lock() method. Internally, gzopen() actually returns a gzip stream, rather than a file stream. I'll update the flock() manual page to make the limitations on the stream types supported clearer.

Test script: --------------- <?php $fp = gzopen("filename",'wb'); if (!$fp) die("gzopen() failed\n"); if (!flock($fp,LOCK_EX)) die("flock() failed\n"); print "Success\n"; ?> Expected result: ---------------- Success Actual result: -------------- flock() failed ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52366&edit=1
