Bug description:REQUIRE_ONCE,REQUIRE,INCLUDE & INCLUDE_ONCE do not handle flock
correctly
Description:
------------
When an exclusive lock is set on a file (flock) importing the file from any
script (including the script itself) with require,require_once,include or
.
include_once silently fails and imports nothing.
Trying to lock the file from the same script works as expected.
Test script:
---------------
<?php //setLock.php
$theFile = fopen('thefile.html', 'rb'); //template file
flock($theFile, LOCK_EX); //accuire an exclusive lock on the file
sleep(10);
echo(require('someFile')); <-- this silently fails
flock($theFile, LOCK_UN );//release the lock
echo(require('someFile')); <-- this succeeds
phpinfo(); ?>
//////////////////////////////////////////////////////////////////////////////
<?php //getTheLockedFile.php
echo(require('someFile');) <-- this silently fails
?>
Expected result:
----------------
When excecuting setlock.php I expect it to succeed on both instances or die
with the first require attempt
when simultaneously excecuting getTheLockedFile.php I expect excecution to
be halted untill the setLock.php file completes or to die with an error.
Actual result:
--------------
When excecuting setlock.php the first require attempt fails silently
(return
value 1, no error) the seccond attempt succeeds as normal.
when simultaneously excecuting getTheLockedFile.php the require attempt
fails silently (return value 1, no error)
