DDC-1909: Getting Fatal error Call to undefined method Doctrine\ORM\Mapping\ClassMetadata::getSqlExecutor() #2576
Comments
Comment created by @Ocramius: Can you try namespacing your caches (metadata/query/results) and see if the problem persists? |
Comment created by @beberlei: We need the complete bootstrap configuratino and options. |
Comment created by gamesh: DoctrineCache.php is a controller plugin that runs first and initializes doctrine cache usually memcache servers Bisna initializes Doctrine based on options and integrates it into ZF as you can see all caches are namespaced, and i'm currently the only one using system locally so no cache conflicts should occur even without namespaces |
Comment created by @beberlei: Can you show one of your controller actions/model services where this error occurs, explicitly the code that generates the ResultCache keys. |

Comment created by @Ocramius: You should definitely namespace your cache (with something like Doctrine\Common\Cache\ApcCache#setNamespace() for example), since you're manually defining your cache key here... Is the explicit usage of the cache ID intended? [~beberlei], should the fetched cache items be checked for their type? |
Comment created by @beberlei: What are the contents of $urls and $possible_match? You should namespace them even further in your code:

Comment created by @beberlei: This isn't related to the result cache, but to the query cache though i just realized. However i don't see any way this is possible, the DQL Query Cache key is generated as a hash, the Metadata cache entry is generated using the ClassName as key. I don't udnerstand how the Metadata could end up in a Query Cache key. @Ocramius As a fix, in AbstractQuery and ClassMetadataFactory, we should check if the return value is really instanceof ClassMetadata or ParserResult. And if that happens throw an error. Also we should prefix the metadata and DQL queries ourself. |
Comment created by gamesh: $urls is an array of URIs array('/tv/samsung/lcd', '/tv/samsung', '/tv'); i'm setting the namespace in the configuration, and providing a unique id for each result cache. the documentation isn't clear |
Comment created by @beberlei: can you try setting different namespace for Query and Metadata cache? They seem to use the same prefix. Only the Result cache uses its own prefix. |
Comment created by @Ocramius: [gamesh], setting different caches for query, results and metadata allows you to have, as an example, 3 caches writing/reading from APC. If you set a namespace for those caches, those won't collide (everything is handled transparently). Anyway [beberlei] is correct when he states that this shouldn't happen here. Even if your approach isn't correct (you don't need to explicitly set any cache key here, plus you should be using namespaced caches) the issue seems to be valid... Does this happen also with a clean cache? |
Comment created by gamesh: i'm not sure, about the clean cache, it just doesn't happen all the time so it's hard to check. If i remember correctly i flushed the cache, and the error appeared, after a few refreshes it disappeared, without flushing cache. it sorta appears and disappears from time to time. even if i don't set the namespace for my caches i have a local memcache, so no cache collision from other projects shouldn't occur |
Comment created by @beberlei: Added a guard to avoid this problem. Its not a real fix, but i cannot come up with the a way to reproduce the problem that you have exactly. |
