cabal-cli

cabal-cli copied to clipboard

After roughly a 24-48 hours it will always crash with a javascript out of heap space error (memory leak). This is with one cabal open (the default one) and not much activity.

It's been happening for the last few versions (at least). Fixing this ought to be the top priority, even if it's something in an upstream library.

I continue to get this as well.

This seems to be cli-only, the desktop app does not have a memory leak.

Is there special library that cabal-cli is using to render things that might need investigation/updating?

Is anyone running a cli with --seed that is also crashing? If yes, it would clarify whether it's related to rendering.

@noffle I looked on my vps, looks like I'm getting

 (node:29410) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 error listeners added to HypercoreProtocolStream(

But it is not crashing, it seems to be just a warning.

A crash report here. I couldn't get all of it because the screen froze. Version is 13.1.6

data point: I am not. Both of my instances that are crashing are Linux (Ubuntu and Debian) with just "cabal" as the command.

i just started a separate process on a vps, seeding the public cabal without the cli rendering. i'll post again in a few days sharing if it crashed
