Bug description

Since all serialization-deadlock issues (like #22482 or #27904) are closed or blocked, preventing new comments, I need to open a new issue to add some information.

I've set up a new Nextcloud-instance and during the process of initial upload I run into lots of serialization-errors as described in the issues. The next time the sync runs I occasionally run into conflicts which should be impossible because - as mentioned - this is an initial upload of files from one client, so it's impossible that a second client uploaded a different version of a file at the same time. I don't have many measure points but it looks like the files on the server are always smaller than the local ones, giving me the impression that they are incomplete uploads not recognizes as such on the server side. The deadlock-messages are the only messages that happened during upload so I think these two issues might be related.

If that's the case, the view "nothing serious, the process just repeats the next time" isn't 100% correct because there seem to be cases where corrupt data resides on the server after such an error that might be downloaded by other clients before the fixing reupload starts.

Steps to reproduce

See reproducing steps in the other issues about this issue.

Expected behavior

An incomplete upload should be recognized by the server (if that's what's happening leading to the effect)

Can report the same, #29985 is another one. Simply unpack something like ghidra (easy example), and upload it through the desktop client ("Network Error:99") or through the webui ("An exception occurred while executing a query: SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock;").

@kimmerin There is an open one #6899 - and my solution to reduce deadlocks by changing indices on table oc_filecache. Can you check https://github.com/nextcloud/server/issues/6899#issuecomment-1377954159 and leave a thumb up if it works?

Feb 16 '23 19:02 obel1x

Hi, please update to 25.0.7 or better 26.0.2 and report back if it fixes the issue. Thank you!

My goal is to add a label like e.g. 26-feedback to this ticket of an up-to-date major Nextcloud version where the bug could be reproduced. However this is not going to work without your help. So thanks for all your effort!

If you don't manage to reproduce the issue in time and the issue gets closed but you can reproduce the issue afterwards, feel free to create a new bug report with up-to-date information by following this link: https://github.com/nextcloud/server/issues/new?assignees=&labels=bug%2C0.+Needs+triage&template=BUG_REPORT.yml&title=%5BBug%5D%3A+

@szaimen Hi Simon, please at first have a look at my explanation here: https://github.com/nextcloud/server/issues/29985#issuecomment-1531535714

As long, as filehandling while uploading is not changed, that error will persist. I would rate it mayor as it affects basic functionality and occurs very often doing some trouble (e.g. needs to upload files again, show errors that are not inituitve). I dont' think anyone did take a look in neither version, so this will not change either (or had someone?).

There are some ways to reduce occurence, like:

Use Postgres
Remove Indices (as explained here: https://github.com/nextcloud/server/issues/6899#issuecomment-1377954159)
Try some DB-Tweaks in config

But they ALL do not solve the Problem itself (while 2. would dramatically reduce database size by half for the caching table without loosing functionality)

Please do not close those issues, as this only makes more "paperwork". The problem will not solve without adjusting the code, so only way to get rid of issues is to changed that part. I would love someone to take a look at those directory- size- calculations and make it fast and relyable for the future. Imo Nextcloud is just too good for those nasty bugs :) hf and gl

Hi, there have been patches to address this issue that will land in 26.0.3. Can you please verify if 26.0.3-rc1 improves the situation around this issue?

Jun 17 '23 07:06 szaimen

I'm on 27.0.0 and the error persists

This issue has been automatically marked as stale because it has not had recent activity and seems to be missing some essential information. It will be closed if no further activity occurs. Thank you for your contributions.

As written before, the problem is still there will be there until filesize calculations are rewritten. For a full explanation about this see https://github.com/nextcloud/server/issues/34697#issuecomment-1556975080

Maybe the same...

Happens here too, using the Helm Chart and it happens with sqlite, mariaDB and PostgreSQL.

Postgres spews a lot of:

ERROR:  duplicate key value violates unique constraint "files_versions_uniq_index"

After that.

Also with and without Redis for locking.

Versions:

28.0.4.1
