Long Pauses Rendering Notebooks On Initial Load with Code-Server

[jlewi]

I started noticing that when I would try to open a notebook it would take a really long time to render or might not render at all.
I'll have a couple notebooks open and then try to open a new notebook and it will take a long time (10s of seconds -minutes) to render.

I'm running runme in code-server and then accessing it in the browser. So it could be particular to that setup. I haven't tried to see if this problem occurs in other settings.

It seemed to be working fine for most of the day and then this problem started occurring.

I can open the file in the markdown editor just fine. So my suspicion is it has something to do with serialization.
The next time I observe this I'll try clearing the app data in the browser and seeing what happens.

I've tried reloading the window and that doesn't seem to help.

Would you mind adding a video clip @jlewi? I just tried it myself, and it opened instantly.

The very first open (and every 30d) might take a few seconds longer (entropy for pk) because Runme is rotating its CA. Sounds like that is not it in your case.

Will do. FWIW, I recognize this is an unhelpful bug report and don't know how to reproduce it. I think its reasonable to close it as unactionable. I mainly wanted to start a record where I could start to log information.

Here's a video; I had to record with GVC so its not as nice as with screen recorder.

Here's what the video is showing

• I just opened a brand new notebook build_tensorrt.md and its "spinning" trying to load it
• I try to click on the buttons to add a code cell or markdown cell and nothing happens
• I click on the M window and instead of seeing the markdown for the new notebook I get a different file
• I then right click and say open in text editor for build_Tensorrt.md
• Interestingly, the raw markdown shows a bunch of code cells
  • Presumably these are the result of click on the add code cell button; but they aren't rendering.

Here's another example.

• When the video starts I have an open file build_tensorrtllm.md which isn't rendering
• I click on M and it doesn't show up
• I then close it and reopen it and it doesn't render
• When I look at the RunMe logs we see a bug from the GrpcProgramRunner about not being to write to a closed program session
• I reset the session and try again and it seems to render.

Are there any suspicious-looking logs in Output->Runme (bottom panel)? My guess is that they're related to task discovery, where we traverse the repo's tree for markdown files.

Perhaps related to this #646.

I just remember that I've seen issue like this on Remote Workspace when I have a local runme binary set in my extension settings, such as:

"runme.server.binaryPath": "/Users/sourishkrout/Projects/stateful/oss/runme/runme"
