FIX #38801: Missing metadata for chunked upload #41149

@cfiehe cfiehe commented Oct 27, 2023

Summary

This commit fixes the problem with missing metadata for chunked uploads, reported in #38801.

The problem is caused because the directory name e.g. web-file-upload-2802b0e2a4ef8eeea70f258257d03b7-1698172388825 is used as key for the cache entry that contains the upload id, the upload target path and the upload target id. Refer to:

$this->cache->set($this->uploadFolder->getName(), [
self::UPLOAD_ID => $this->uploadId,
self::UPLOAD_TARGET_PATH => $this->uploadPath,
self::UPLOAD_TARGET_ID => $targetFile->getId(),
], 86400);

In later calls, when the cache entry should be retrieved a relative path like uploads/c.fiehe-local/web-file-upload-82802b0e2a4ef8eeea70f258257d03b7-1698172388825 gets used as key. Refer to:

$this->prepareUpload(dirname($request->getPath()));

This retrieval results in a cache miss, that causes the upload to fail with files larger than the configured upload chunk size (defaults to 10 MB). When the log level was set to debug, the log contains the error message Missing metadata for chunked upload.

I think this would break getting the actual upload folder in prepareUpload. I also cannot see this bug happening on my s3 test setup.

The directory name is already being used within the prepareUpload method https://github.com/cfiehe/server/blob/fix_missing_metadata_for_chunked_upload/apps/dav/lib/Upload/ChunkingV2Plugin.php#L314C51-L314C51

Just a question for checking an idea: Do you have either redis or apcu setup for caching? Can you maybe share your occ config:list output?

My guess is that you don't have a proper cache and therefore getting the metadata fails. With your patch getting the upload folder fails but the NotFound exception is catched and returning early which leads to the regular chunking plugin to be taken as the fallback.

} catch (StorageInvalidException|BadRequest|NotFound $e) {
return true;

The strange is, that the problem arises when you have multiple Nextcloud servers. We have an active-active loadbalanced cluster which consists of three Nextcloud servers. When you have only one server, the upload succeeds, but in a multi-node setup it fails.

This is our configuration. We use a small NFS share, where the Nextcloud sources are stored, so the three servers share the same configuration. Is there any issue here?

Is the redis server shared between both instances?

Yes, we are using a virtual IP in order to access the Redis Sentinel Cluster. This IP always points to the primary node. The Redis cluster runs on three dedicated virtual machines.

I have found the problem. It was a typo in the configuration file 🙈. I wrote memcache.disributed instead of memcache.distributed. Everything is working now and large files are being uploaded without any issue.

@juliushaertl Thanks a lot for the caching hint and my sincerest apology for generating efforts.

No worries I think this still needs a proper fix to not fail if no distributed cache is available, I can check that next week.
