Summary: PECL sync readerwriter lock problem
Status: Feedback
Type: Bug
Package: PECL
Operating System: centos 6.2
PHP Version: 7.1.10

New Comment:
As the author of the extension, I agree. The first write lock call fails
because there is still a read lock. The second write lock call succeeds since
there are no read locks. The third write lock call fails since there is
already a write lock.
The test suite is carefully calibrated to cover the widest range of
locking/unlocking scenarios with as little code as possible within a single
process space (i.e. if something is locked, then it will not wait and will
immediately return false). Are you encountering a test suite validation error
when running the tests?

No? The first writelock was denied because there was still a readlock in place.
var_dump($readwrite->readlock(0)); // shared lock #1 - true
var_dump($readwrite->readlock(0)); // shared lock #2 - true
var_dump($readwrite->readunlock()); // unlocked #2 - true
var_dump($readwrite->writelock(0)); // still locked by #1 - false <<<
var_dump($readwrite->readunlock()); // unlock #1 - true
var_dump($readwrite->readunlock()); // not locked - false
var_dump($readwrite->writelock(0)); // exclusive lock #1 - true
var_dump($readwrite->writelock(0)); // locked by #1 - false
var_dump($readwrite->readlock(0)); // locked by #1 - false
var_dump($readwrite->writeunlock()); // unlock #1 - true

Description:
------------
In the tests\014.phpt, the last fourth expect result should be bool(false), not
bool(true), because the fourth writelock has not unlocked.
var_dump($readwrite->readlock(0));
var_dump($readwrite->readlock(0));
var_dump($readwrite->readunlock());
var_dump($readwrite->writelock(0));
var_dump($readwrite->readunlock());
var_dump($readwrite->readunlock());
var_dump($readwrite->writelock(0));
var_dump($readwrite->writelock(0));
var_dump($readwrite->readlock(0));
var_dump($readwrite->writeunlock());
?>
--EXPECT--
bool(true)
bool(true)
bool(true)
bool(false)
bool(true)
bool(false)
bool(true) <----Here should be false
bool(false)
bool(false)
bool(true)
