Bug #61201 [NEW]: LOCK_EX in file_put_contents with custom streamwrapper fails

From: Operating system: Win7/64 PHP version: 5.3.10 Package: Filesystem function related Bug Type: Bug Bug description:LOCK_EX in file_put_contents with custom streamwrapper fails Description: ------------ Currently I'm using a custom Streamwrapper for memcached access. The wrapper works fine unless I'm using the LOCK_EX parameter for file_put_contents. If the parameter is given the function does neither write the file nor calls a method of the streamwrapper. I included simple echo statements in all methods of the streamwapper but no output is shown. I have done this because there is no documentation about which streamwrapper methods are called during file_put_contents. I ASSUME that it should call stream_lock like flock() does - but as mentioned before there is no output at all. Test script: --------------- class MyWrapper { // Assume other methods are implemented // Just for demonstration public function stream_lock($operation) { echo "I've been called"; } } stream_register_wrapper('myWrapper, 'MyWrapper'); $result = file_put_contents('myWrapper://myFile','content',LOCK_EX); echo $result; Expected result: ---------------- true (file is written) Actual result: -------------- false (file is not written) -- Edit bug report at https://bugs.php.net/bug.php?id=61201&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61201&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61201&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61201&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61201&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61201&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61201&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61201&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61201&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61201&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61201&r=support Expected behavior: https://bugs.php.net/fix.php?id=61201&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61201&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61201&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61201&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61201&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61201&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61201&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61201&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61201&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61201&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61201&r=mysqlcfg
