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)
