[New Issue]: Seeing Two collaborative sessions warning occasionally when creating a new file #245

jzhang20133 · 2024-03-06T17:38:29Z

Description

We are occasionally observing an error dialog when opening up a new file that says there are two collaborative sessions are created for this file.

Reproduce

We haven't found a way to reproduce this reliably. It feels a bit flaky, though I have some suspicion on where this is coming from, mentioned below. Here is are the series of logs we need:

Expected behavior

Dialog should not be popped up when one user is accessing.

Context

Suspects

FileLoaderMapper dict is not thread safe. When there are concurrent calls to create file loader, two file loaders could be created and one of the file loader will be referenced from dict in FileLoaderMapper. Both file loaders could have watcher tasks running and for file loader which is not saved in dict, the last_modified field is incorrect and it will report out-of-band changes all the time.

This should only happen when two views of the same file are opened simultaneously (even for only one user), for instance a notebook file opened with the notebook editor and with the text editor.

We've seen this flaky message too in JupyterCAD. It has been especially annoying in our visual regression tests.

Given that the end-user cannot do much about it (except pressing "Ok") I would vote for only showing a warning in the console, not in a pop-up window. Pop-up windows should probably be avoided as much as possible.

The user is advised to close one view, so they can do that.

I would vote for only showing a warning in the console

I don't think end-users have the console opened, so in practice nobody will see this message.

But I agree that this behavior is not ideal (see #139 (comment)). Note that I reverted a change that was going even further in this direction.

I found another possible scenario that this could happen when user just has one view. When the first websocket request fail in line 105 in prepare(), basically if exception is thrown between line 87 to line 105, then this first websocket failed. After that, another websocket get request comes in for same file because UI will retry to establish a new websocket. For the second websocket, in prepare() method, we will find there is an existing fileLoader for this file_id, hence the warning sign will show up when user only have one view of the file. cc @davidbrochart

davidbrochart · 2024-03-08T07:59:12Z

Good point, could you write a test that reveals this behavior?

Closing as fixed by #289, please reopen if it is incorrect.
