30,xcache_get_for_update/xcache_lock/xcache_unlock (was Integrated locking system),Martyo,moo,"I would like x-cache to introduce an integrated locking system. Take for example this inefficient locking method:

{{{
while(xcache_get(""lock_test""))  { // check if lock exists
	usleep(10); // wait for 10ms
	$waittime += 10; // add wait time to variable
	if($waittime > 10000) { // check if we've been waiting for 10 seconds
		break;
	}
}
xcache_set(""lock_test"", true); // set the lock
$the_cache_test = xcache_get(""test""); // load the test cache into PHP
array_push($the_cache_test, ""a test""); // do some stuff here, change $the_cache_test
xcache_set(""test"", $the_cache_test);
xcache_set(""lock_test"", false); // unset the lock
}}}

Instead of this, I would suggest adding a locking value to xcache_get and xcache_set, like the following:

{{{
$new_method = xcache_get(""test"", true);
array_push($new_method, ""the new method"");
xcache_set(""test"", $new_method, false);
}}}

The ""true"" part in xcache_get sets the lock for ""test"". The ""false"" part in xcache_set sets the lock for ""test"" to false. If xcache_get is called and the lock is set, then xcache should sleep for 10ms and check again (this should be defined in the xcache PHP.ini settings)",enhancement,new,trivial,4.0.0,cacher,1.2-dev,,,,,,,0,,,,
