Errors and Problems don't update from /lib/bs/compiler.log

[marcoemrich]

this might be a duplicate of #34. I post it as a new issue since it has nothing to do with Angular or a specific project.

Description: VS Code does not update errors (or the lack of) from the complier-log. Neither Problem-View nor "red underlines".

Since this a very basic function, I suspect it has to do with my environment which is Node 14, Ubuntu 20.04 and VSCode 1.52. I used a new clean build of VSCode and only installed rescript-vscode 1.0.2.

Steps: See the the Video to reproduce

update_issue.mp4

Observations:

• The Compiler-Log is always correct
• Restarting VSCode updates the VSCode views, but it still does not update again

Thanks so much for all your hard work. Let me know, if I can do anything to help track down the issue. (I'm very dedicated, this is the only issue that prevents my team to switch to ReScript).

It gets weirder :( I tried to debug the extension. When I set a breakpoint at the beginning of "sendUpdatedDiagnostics" in the server.ts - and press "continue", it just works. As soon as I remove the breakpoint, it stops working :(

Update: I found the issue! It is a race condition with chokidar and fs.readFileSync. It can be fixed by provideing an option to chokidar.watch like described here https://stackoverflow.com/questions/60460751/getting-empty-string-from-fs-readfile-inside-chokidar-watchpath-file-onchang

I experimented and found out that a treshhold of 1 millisecond is enough:

awaitWriteFinish: {stabilityThreshold: 1}

PR will follow!
