The api is sometimes unresponsive when running in electron

[Powersource]

How to reproduce:

1. Clone https://github.com/Powersource/ipfsd-ctl-no-start
2. Make sure you're running a compatible node version.
3. npm install
4. node index.js id() should print every time.
5. npm start (i.e. electron) and open the console. id() prints around 25%-50% of the time.

Been haunted by this bug or variations of it for quite some time.

I haven't been able to reproduce the issue. What os are you on?

[Powersource]

Arch Linux

Anything I should try/any debug info that would be helpful? I'd be willing to help out with fixing this if I only knew where to begin :P

[dryajov]

@Powersource that would be awesome, any help is always welcome!

• Could you please verify that both your original implementation and your sample repo are using non-disposable repos (disposable: false).
• Can you also run with debug enabled - DEBUG='ipfsd-ctl:*' npm run start, and attach the output of a failed run here? The debug output should show up in the console in your electron window.

About to go to bed but I can already say that I haven't tried with a non-disposable repo for quite a while. Both the app and the linked example are set to disposable.

Tried to replicate on my laptop (arch too, disposable nodes for now). I didn't manage to break it completely, but the 50% chance of it working correctly is still there. When it didn't work instantly it instead, very consistently, took very close to 1 minute (just below) to print id():

I'll try a non-disposable setup later.

I tried with a non-disposable node iirc but that didn't help.

However, I just now upgraded from electron 1.8.4 to electron 2.0.2 and it works great now! Most of the time instantly, sometimes takes a few seconds but probably not more than 10 at most. So happy this is fixed, I was going crazy 😂 🎉 🎉 🎉

There are a lot of bug fixes in the electron 2 announcement, not sure which one would have helped. There are 2 mentioning custom protocols but that seems to have been backported to 1.8.4. There's one about graceful shutdown on linux, might have been that one if the laptop in your profile pic @dryajov is a mac :P
