Desktop client not syncing changes

[hriekehof]

I updated Nextcloud and Groupfolders recently to 16.0.4 and 4.1.0. With GF 4.1.0 the sync of files by the desktop client is only working in some cases. These are the cases i observe.

1. When i create a file locally it gets synced by the desktop client to the server. But not to other clients automatically.
2. When i create a file in a groupfolder on the server its not getting synced automatically by any desktop client
3. Files get synced when i start a manual sync in the desktop client.

I downgrated GF to 4.0.5 and the sync problem is gone. Everything is synced quickly after it is changed in the browser or locally by the desktop app.

There was also a short discussion in #590 but it was bascially another problem.

I also have this major issue. First I was under the impression that it was the desktop client because I do not have this bug using the Mac client. But it might be related to something else.

Here's the full log and discussion about it:
nextcloud/desktop#1430

I am sending a notification to all my users to use the force sync for now.

[patricksebastien]

Would it be possible to have a label on this. Surely we are not alone using group folder + desktop client. Downgrading to 4.0.5 is not ideal (I fear this move, I am using group folder with advanced permission).

I also can add that my observation was only with the windows desktop client. I didn't do any test with the mac client.

[gvansanden]

Sound like my issue indeed but it did work with 4.1.0.
I tested Mac, Windows and Linux clients, versions 2.5.2, 2.5.3 and 2.6.0, I also tested with the OwnCloud client, the issue was present in all versions across platforms

[gvansanden]

@hriekehof How did you do the downgrade? I think I'll also have to do that

[hriekehof]

@gvansanden basically the following

1. Maintenance mode or something which makes your Nextcoud inaccessible by users
2. Deactivate the current Groupfolder App in Adminarea
3. Download the Version you want from the Store
4. Unpack it in the custom_apps folder and overwrite the current version
5. Active the Groupfolder App in Nextcloud
6. Go out of Maintenance mode

[gvansanden]

@hriekehof I did the same steps earlier, but the app still shows as 4.1.3 in the list, do you also have that?

[gvansanden]

@hriekehof Downgrade worked. But I went to 4.1.0 which was working before. The issue stays...

[gvansanden]

Downgraded to 4.0.5 and everything started working again... Not fun

[gvansanden]

I'm going to move away from groupfolders in favor of folders shared by a non-active user. Too many sync issues with them and activities are broken. Nice concept but not worth it.

[derdershat]

have same problem here... with downgrade to 4.0.5 it is back working.
I use old Windows Client 2.3.3 (because of missing notification in newer versions).

this is a big issue. could this be taken on a higher priority?

[hriekehof]

is this fixed with the new desktop client version 2.6 ?

[gvansanden]

@hriekehof No, it is server side

[patricksebastien]

@gvansanden Meaning nextcloud 16.0.4 or the groupfolder plugin? Since it's working for 4.0.5, I think it is safe to say that the bug is in the groupfolder plugin.

@icewind1991 Did you had the time to look at it. Do you have an idea?

[gvansanden]

@patricksebastien It's a bug in the groupfolder plugin for sure. Not the client or Nextcloud core. Groupfolders and sync are a headache that's not worth it

[TP75]

NC-Server 16.0.4.1, groupfolders 4.1.3, Debian 10.1, PHP 7.3.9
NC-client version 2.6.0stable (build 20190927), MacOS X / macOS Sierra 10.12.6 & Mojave 10.14.6

I updated Nextcloud and Groupfolders recently to 16.0.4 and 4.1.0. With GF 4.1.0 the sync of files by the desktop client is only working in some cases. These are the cases i observe.

same here

1. When i create a file locally it gets synced by the desktop client to the server. But not to other clients automatically.

almost same. However, an addendum to (1.) should be:

• any unknown server content syncs to the client if a new local file gets synced to the resp folder
• folder content gets synced after the client re-connects & syncs e.g., after WLAN de-activation/re-activation

2. When i create a file in a groupfolder on the server its not getting synced automatically by any desktop client

same here

3. Files get synced when i start a manual sync in the desktop client.

same here

4. A fresh established client account gets a one-time sync if another client syncs. Apparently falls back to (1.) afterwards.

Hope this helps.

[patricksebastien]

The bug is somewhere between 4.0.5 and 4.1.0:
v4.0.5...v4.1.0
11 .php files changed - I am looking to help as much as I can.

Is this file use for the sync process:
https://github.com/nextcloud/groupfolders/blob/ae0794945b0170fa2ea6f56b7c3931af4a5a800b/lib/Mount/MountProvider.php
getMountsForUser()

Groupfolder is an important app for nextcloud (without it I cannot use nextcloud (advanced permission)). But the desktop client is also very important to my users. I am sure I'm not alone using both.

[gvansanden]

@patricksebastien I agree, but it causes so many issues. Activities are broken on GF, putting items in trash locks up clients often as they still have a reference to a file they can no longer access. I'm sharing folders from a meta user for now.

[thoro]

Also affected, is there a work around instead of downgrading the app - which seems to break my instance somehow ..

Has anyone figured out what is happening?

[wiswedel]

Could you please try reproducing once again with

• Server 16.0.5
• Group Folder 4.1.3
• Desktop client 2.6.0

[gvansanden]

@wiswedel I had the issue on that combination (now rolled back)

[wiswedel]

Alright. Reproduced it now also on

• Server 16.0.5
• Group Folders 4.1.3
• Desktop client 2.6.0 (and 2.6.1 RC1)

and also on

• Server 17.0.0
• Group Folders 5.0.3
• Desktop client 2.6.0 (and 2.6.1 RC1)

Extra info: once any change is made to a normal folder on the server (or another connected client), the group folder sync gets triggered also - but not if changes on the server have been made within a group folder only.

[rullzer]

Sounds like somehow somewhere an etag is not propagated.

[thoro]

I have setup a testing instance now, but I have the same issue with 16.0.5 and 4.0.5. Possibly the issue is different from the other guys.

For me the local sync NEVER happens, even if I Force Sync. Only when I uncheck and recheck in the client it will sync.

It's a multiple times nested groupfolder, I assume this might be the issue.

It's 5x nested. With a group folder nested only 3x it works completely fine. (with GF 4.0.5)
And was not working either with the 3x nesting with GF 4.1.3

During testing I only had the relevant folders checked as to be synced

[TP75]

Have a look at:

Hey,

we've just released 2.6.1 RC1 which is built with Qt 5.12.5 on all platforms (also has OpenSSL 1.1.1d, so it features TLS 1.3).

You may give it a try:
https://github.com/nextcloud/desktop/releases/tag/v2.6.1-rc1

copied from comment NC 2.6.0 client shows an unstable GUI window on Mac OS X after first config
#1501

Maybe the task of improving the RC1+ relates to the above?

[TP75]

It's a multiple times nested groupfolder, I assume this might be the issue.

@thoro Please clarify the technical nature of "a multiple times nested groupfolder" if possible.

[thoro]

@TP75 The group folder mountpoints are nested i.e.

each line represents one group folder:

/Level1
/Level1/Level2
/Level1/Level2/Level3
/Level1/Level2/Level3/Level4
/Level1/Level2/Level3/Level4/Level5

Each level contains various different permissions.

With the new permissions features this could be solved easier - once it's stable.

[patricksebastien]

@thoro Are you using advanced permission?

[thoro]

@patricksebastien not yet, plain old group folders

[rullzer]

So, I think we found it. #647 fixes this. (it causes #648 again but we have to find another way to fix it then).

We'll release a new patch release soon.

[juliusknorr]

Fix release with 4.1.4 and 5.0.4

[Patrock]

on my system i have sync issues with groupfolders , too...

NC-Version: 24.0.5 (and previous 23.X) -> running on docker(Compose)
Group folder version: 12.0.2
Desktopclient Version: 3.6.2 (Windows)

The problem:

1. create groupfolder for group with User A & B
2. add files to webui (A)
3. no sync for user A & B
4. force sync by client A&B -> files appear
5. add files to desktop folder for A
6. files are synced to server but not to User B
7. wait .. .wait ... wait. ... nothing
8. force sync on B -> files appear

also on nested groupfolder setups, in one case (our working structure with nested group folders) even a forced synced does not work...

there are no logs to this issue.

What always works: untick folder in client and retick -> everything in sync...

normal syncs (with shared and owned files) are working fine

is there something i could test further ? Someone with similar problems ?

Thx

@Patrock - Presumably you should file a new bug report i.e. new issue for this if your a.m. problem persists.
