Expected Behavior

Sync should terminate.

To Reproduce

I might be specific to my bookmarks, but generate a bunch of bookmarks and they try to query them? I'm not sure. If there were logs of failed requests, I could be more specific. But I have no idea which request is failing. I tried calling every request listed in the logs, but they all succeed.

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 a few years ago, 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!
To continue the development and maintenance of this project in a sustainable way it is expected that you donate to the project when opening a ticket,
if you're not a donor already. You can find donation options at https://floccus.org/donate/. Thank you!

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 Nextcloud 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 💙

Hey @LoveIsGrief
https://nextcloud.internal/index.php/apps/bookmarks/public/rest/v2/folder/-1/children?layers=1 seems to be the request that times out, that shouldn't happen, but can happen when the folder is not cached on the server yet. Since all requests are succeeding when you run them manually now it's strange that the requests from the app timeout. Do you have all your bookmarks in one folder?

Hi @marcelklehr

Many bookmarks are indeed in one folder. I moved them out of folders because firefox would slow down immensely when opening the bookmarks with many folders and subfolders. I use tagging extensively.

The request is ~18MB gzipped and transfers in 10-20s (~1MB/s). Maybe the timeout could be configurable?

I checked the API and the bookmarks aren't paged, but the bigger problem is that the bookmarks have a textContent and htmlContent field, which seems to contain the entirety of the bookmark ☹️

It's weird because "Auto Archiving" isn't on

Maybe using the GET /public/rest/v2/bookmark, filtering by folder and paging the results could help too?

Edit: If indeed folders/.../children is the one timing out, then it's only called by this function, which could probably use /folder/ to get the tree and /bookmark/ to page through each folder.

I wouldn't know how to test it though :/ Is the code used for both the android and the browser app?

Yeah, it's the same code. Thanks for looking into possible fixes!

That's a good idea! Since you say the request is only 10-20s I'm not sure if the client-side timeout is the issue. it's set to 300s seconds at the moment.

If that request is not timing out, then I wonder, would it make sense to log the stack? Or is there some other way to find out which request is timing out?

I'm also wondering if there error is actually correct. Maybe it's running out of memory as it's 22MB of JSON, but that's just an assumption. For some reason this does work in the browser, but not on Android.

I'm pretty certain it's this request, because all other requests have a log entry that says "receiving response".

For some reason this does work in the browser, but not on Android.

That's peculiar indeed.
