Description

Hello everybody,

we have a really big problem with our TYPO3 6.2 system. If I try to update, install, enable or disable an extension, the process break with random error messages. Always some classes can not found. We found out, that the generation of temporary classes in typo3temp/Cache/Data/cache_classes not generated completely or correctly, if the frontend website is calling in the same time. Every action (update, install, enable or disable an extension) in the extension manager is really slow (up to 1 minute). It looks like the extension manager generate all the cache classes new and if someone else calling the website in this time (like on a live system), the class cache is broken. The backend and the frontend is down. Only class not found error messages displayed. It is really hard to bring the system up. The only way is to stop all access to the frontend by a firewall for example, clear all cache files in typo3temp and call the backend and waiting for a successful request. Then everything runs fine.

Our system setup:

TYPO3 6.2.3
PHP 5.3.28

We enable and disable APC. No difference in the behaviour.

Sounds a little bit related to my issue here: #59662
where LocalConfiguration.php is not written while read in again

  • Target version deleted (next-patchlevel)
  • Complexity set to nightmare

Well this seems to be exactly the problem we were trying to solve before the 6.2 release. I invested a week or so in the topic of locking/process synchronization.
The bad news: It can't be done reliably in PHP on a general implementation. I'm sorry.

I could be done, if some system requirements are fulfilled.
If you're interested, read my blueprint: http://wiki.typo3.org/Blueprints/LockingForCaches

Also if we save the extension settings, all cached classes are regenerated and if you do it on a live system, the complete system crashes with class not found error messages. What are the plans to fix this nightmare issue?

Why is this necessary to regenerate all cached classes by updating the extension settings? From a performance perspective it is really slow.

Ok that is strange. Saving extension settings shouldn't actually clear the classes cache. That does not make sense.

We should move the "extension setting" thing to another issue to stay clean on this one.

The main issue on this one seams that to much time is needed between "clearing the cache and rebuilding" maybe something scary happens (up to 1 minute? Realy?).

We should take a look again, if EM looks the cache generation while he clears and rebuilds the cache. I think thats the thing where the nightmare begin and on the other side, thats one point which isn't supported by the caching FW (we should consider in the rewrite, that we need something like "flushAndRewrite()").

It could take days to get a somewhat "hacky" solution. :-(

There are even more thread collisions on extension updates.

The issue with "extension setting" was moved into #59966
The added patch was also moved there as it only fixed the "extension setting" point.

Tobias, I created a separate ticket #59966 for the extension configuration setting problem and pushed a patch.

Regarding your initial problem: I had a look again at that code too and I'm a bit confused, since what you describe should actually be fixed and that would mean that locking fails on your site. Can you please take a look into your log module and search for messages like:
"Waiting for a different process to release the lock" or "Unlinking stale lockfile"

I tried to reproduce the error on our test server, but the result is different. If I deactivate an extension for example and call the website in the same moment, I get the following error:

There is nothing in the log module, because the request in the backend or frontend stops the process with an PHP error message.

So you're sharing typo3temp via NFS?

Yes. The complete webroot is shared via NFS.

Then you've the root cause. Locking very often does not work over NFS.

#1394480725: Could not acquire lock for ClassLoader cache creation.

Usually the solution is to let each server have it's own typo3temp folder, such that caches (and locks) remain local.

@Tobias

How many files do you have in typo3temp/locks ?
Is NFS Caching deactivated?

NFS isn't the best FS for this job you may need to think about a Distributed FS (like DRBD), Cluster or SharedStorage.

Updated by Tobias Klepp over 10 years ago

If each server has it's own typo3temp folder on the local harddrive, will the system be stable with a shared database? Is there a connection between existing cache files and the database?

We did a lot of testing with different maschines. The result is, that we only have this problems on the NFS maschines. TYPO3 4.5 works fine with NFS. Now with TYPO3 6.2 we run into this problem. In the typo3temp/locks directory we found up to 3 lock files always available.

These are the test results (enable/disable extension in extension manager and request frontend in the same moment):

On the windows boxes I can't help.

#1334756737: The temporary cache file "C:/Daten/arbeit/www/typo3_62/typo3temp/Cache/Data/cache_classes/53b275354a026.temp" could not be written.

You need to find out why he can't write the temp file.

On the Linux NFS issue. I meant you need to deactivate the NFS caching. IMHO it should be enough to use lookupcache=none on the client, but I don't have such a system at the moment. More information on performance lose by disabling NFS caching: http://www.sebastien-han.fr/blog/2012/12/18/noac-performance-impact-on-web-applications/
But it might be, that it won't resolve the issue in every situation.

Moving the cache into memcached/redis won't help you as the cache looking only works with "SimpleFile" looking yet.

 #18

Updated by Björn Schmitt over 9 years ago

Don't know if it helps, we had a similar issue with 4.7 which sounds like this one here. TYPO3 crashes when re-building the cache in case the typo3temp folder is shared to many servers because of Fatals caused by competing write requests to the NFS share.

We solved it by linking the typo3temp/Cache folder to a local folder on each server.

Please let me know if it helps.
