flock(): Illegal operation argument

[samijnih]

ErrorException in Stream.php line 176: flock(): Illegal operation argument

1. in Stream.php line 176
2. at HandleExceptions->handleError('2', 'flock(): Illegal operation argument', '/Applications/AMPPS/www/inMindBO/vendor/antecedent/patchwork/src/Preprocessor/Stream.php', '176', array('operation' => '0'))
3. at flock(resource, '0') in Stream.php line 176
4. at Stream->stream_lock('0')

I can fix this error by setting LOCK_EX

Hello,

I assume you get this by calling flock() from your own code. If so, which $operation do you use when it is not LOCK_EX? Perhaps you are missing the second argument of flock(), which is mandatory?

Hello,

I never called flock from my own code (or the Laravel framework does it for me) but I fixed it by always setting the LOCK_EX constant

I use this lib on WordPress instalations. After update to 1.4 the language system is broken.
For now, I need to steek on 1.3.*

Any help on it?

I have found a similar issue with flock on line 192 - the issue manifested because - somehow - this module conflicts with the php codesniffer module.

The main issue seems to be that the stream_lock method assumes that the $operation parameter is going to be a string representation of operation - which is strange because the operation constants should theoretically be available. What I found was that checking the numerical equivalent resolved the issue - however stream_lock doesn't seem to be validating the operation.

I'll check this out when I get to the office tomorrow - but I think the internals of this function could pass in operation as an integer, and that would allow consumers to call it using more appropriate methods - for example stream_lock(LOCK_EX)
