Bug description:fwrite returns 1 when trying to write to a locked file
Description:
------------
When I try to write any length string with fwrite using a file handle I
previously
locked with flock, fwrite is of course unable to write, but will return
unexplicable value 1 instead of false.
Test script:
---------------
/*
Run two instances of this script in a rapid sequence
*/
$fp1 = fopen("/cache/lockable.txt","w");
if(flock($fp1, LOCK_EX | LOCK_NB)){
echo "locked fp1\n";
sleep(20);
}else{
$res = fwrite($fp1, "ABCDE");
if(false === $res){
echo "failed the write\n";
}
echo "I managed! fwrite returned: "; print_r($res);
}
Expected result:
----------------
I expect to read "failed to write" when a second instance of the script is
run,
since fwrite should return false as documentation says when fwrite is not
able to
write.
Actual result:
--------------
fwrite returns integer 1.
