Hello 👋

Thank you for taking the time to open this issue with floccus. I know it's frustrating when software
causes problems. You have made the right choice to come here and open an issue to make sure your problem gets looked at
and if possible solved.
I'm Marcel and I created floccus and have been maintaining it ever since.
I currently work for Nextcloud which leaves me with less time for side projects like this one
than I used to have.
I still try to answer all issues and if possible fix all bugs here, but it sometimes takes a while until I get to it.
Until then, please be patient.
Note also that GitHub is a place where people meet to make software better together. Nobody here is under any obligation
to help you, solve your problems or deliver on any expectations or demands you may have, but if enough people come together we can
collaborate to make this software better. For everyone.
Thus, if you can, you could also have a look at other issues to see whether you can help other people with your knowledge
and experience. If you have coding experience it would also be awesome if you could step up to dive into the code and
try to fix the odd bug yourself. Everyone will be thankful for extra helping hands!
One last word: If you feel, at any point, like you need to vent, this is not the place for it; you can go to the forum,
to twitter or somewhere else. But this is a technical issue tracker, so please make sure to
focus on the tech and keep your opinions to yourself.

I look forward to working with you on this issue
Cheers 💙

Please make sure

• that all your Floccus instances on Chrome (or variants thereof, like Edge, Brave, Vivaldi etc.) are on v5.0.9
• that all your Floccus instances on Firefox are on v5.0.8

Judging from the chrome webstore statistics there are still around 800 Chrome instances on v5.0.6, which has this bug.

[Ganya-A]

请确保

• 您在 Chrome 上的所有 Floccus 实例（或其变体，如 Edge、Brave、Vivaldi 等）都在 v5.0.9 上
• Firefox 上的所有 Floccus 实例都在 v5.0.8 上

从 chrome 网店统计来看，v5.0.6 上还有大约 800 个 Chrome 实例，存在此 bug。

I've updated all device versions to 5.0.9, two EDGE, and one mobile browser, and I'm still having this problem.

[marcelklehr]

So, this should only really be a problem when syncing via WebDAV like @Ganya-A and @idzyr and @beyercj

@InfamousUser is syncing via Nextcloud Bookmarks, which should automatically timeout its lock. Is this still happening for you?

@traviss64 are you syncing via Nextcloud Bookmarks or via Nextcloud files (ie. webdav)?

[idzyr]

@marcelklehr
I have the same issue as the original post, but I'm using a PC with Chrome(v122.0.6261.112). I tried deleting the lock file, but after a while, it stops working again.

[marcelklehr]

This should be resolved with v5.0.10, please let me know if it works :)

[InfamousUser]

Updated to v5.0.10 on Chrome, no change.

[beyercj]

Updated to v5.0.10 on Firefox 115.8.0esr for Linux and to v5.0.11 on Android 11 on Samsung Galaxy A12, no change either on webdav.smartdrive.web.de (webspace almost full). However, synchronisation worked fine on webdav.vodafonemail.de (webspace almost empty), so might not have anything to do with floccus.

[marcelklehr]

So, this issue usually stems from a leftover lock file that prevents all clients from syncing. v5.0.10 should mitigate that by forcing floccus to sync anyway, if it has waited long enough. If this does not fix this for you all, then we might have a more serious issue of an interrupted sync process. This would be the case if for example if floccus does sometimes start to sync but then stops, likely after about 5mins, only to then show the "scheduled Sync" message one minute later, which again stems from the leftover lock file. On firefox I think you can also verify if this is the problem by opening the browser debug log. The browser will then no longer interrupt the sync process and thus floccus should sync correctly after some time waiting for the lock to expire and go back to an "All good" green status, while the debug window is open.

Here's how to open the debug window:

Firefox

• Go to about:debugging
• Go to This firefox
• click on debug button next to floccus entry to open the console

Not sure, if this will work in chrome, but you may try:

Chrome

• Go to chrome://extensions
• enable Developer mode
• click on dist/html/background.html button in floccus' entry next to "Inspect views: " to open the console

[InfamousUser]

I am receiving "QUEUING POST", "FETCHING POST", "Receiving response for POST" and then "Resource is locked, trying again soon" in the Floccus logs. I should note that it did sync the folders to the server, but none of the actual bookmarks are populated.

[marcelklehr]

@InfamousUser You will need to wait until the lock is cleared for the above thing with the debug window to work. Only unpopulated folders is a bad sign, though...

[InfamousUser]

How long do I need to wait? Sever has been off for the past few days, I just turned it on and still the same problem. Is there a way to force this or what am I supposed to do?

[marcelklehr]

Doesn't matter anymore, I've been able to reproduce this now and can debug from there. It looks like Chrome blatantly shuts down extension service workers after running some amount of minutes. There's not gonna be an easy fix for this, I think. Should still be doable though

[smth]

I also have this problem. Two Firefox browsers using v5.0.10 (though one was recently on 5.0.5). My server does have a lock file on it.

[truthsword]

Updated Firefox from 5.0.8 to 5.0.10 and within a short time the lock file imposed itself. Is rollback possible? I deleted the lock file, but can't do that regularly. I'm using WebDAV.

[truthsword]

I delete the lock file ,then remove my account and re-add it. You can try this too, no loss anyway

No need to remove account. Disable all Floccus extensions. Delete lock file. Enable all Floccus extensions. Not something one wants to do multiple times a day.

[marcelklehr]

I'm working on the fix for this. It's quite involved, but I should be able to provide a beta soon, for you to test 🚀

[marcelklehr]

Mh, probably best to disable the original extension instance, yeah

[InfamousUser]

I disabled the real extension in settings. It seems to be randomly syncing more bookmarks but this is not what I would call a working fix. It has synced another 100 or so bookmarks. When you press the sync it latches but then it keeps switching between syncing and scheduled. Bu then after a while it "finishes" and you have to trigger it again because it has not synced the bookmarks.

[marcelklehr]

@InfamousUser Can you confirm whether it syncs for roughly 5 minutes, at least, before it switches back to "scheduled"?

[marcelklehr]

Chrome version may be interesting as well, indeed. Chrome v110+ may be necessary for some of this to work properly

[InfamousUser]

I do not and cannot have Chrome v110+ due to Google blocking updates on older Windows so count me out for testing that...

[marcelklehr]

Oh Wow! So you do have pre v110 Chrome, so the fix I built may work after all. Sorry about the Chrome updates!

[InfamousUser]

Geez, never thought that'd be the issue! I can try it on a different PC, with newer browser, but I have a feeling that will work since it doesn't really help! Will get back to you with the results!

[marcelklehr]

It's not the root cause, but part of my fix only works post v110

[marcelklehr]

Alright, since it works for me I'll roll this out stage-wise in production now to get people to test it.

[marcelklehr]

Staged roll-out failed for some reason, so now this is on prod 100% 🙈
Anyway. @Ganya-A and @idzyr and @beyercj Are you on v5.0.12 already? Does it work now after removing the lock file manually once?

[InfamousUser]

Just to confirm the fix works for me, but everyone already knows I guess.

[marcelklehr]

Thank you @InfamousUser always good to get confirmation :)

[ivanjx]

where is the .lock file on nextcloud?

[marcelklehr]

@ivanjx please open a new discussion or a new issue

[joshqou]

This can still happen on version 5.2.7 if you start and immediately cancel a sync. i.e: accidentially double-click the sync now button. There should really be a button to manually remove the lock file so users don't have to open devtools just to get their bookmarks syncing again

[marcelklehr]

@joshqou Good idea! Can you open a feature request for this?
