Change default port #26

janek26 · 2022-01-04T09:50:45Z

Hey guys,

great work! While integrating this with Argent X we notices port 5000 is often already in use and the devnet doesn't check that and starts anyways (but doesn't work)
After a quick google search it seems like port 5000 is often used by the system on MacOS

would it be possible to change the default port to something less used?

Cheers, Janek

FabijanC · 2022-01-04T18:12:03Z

Can you use the --port option (as documented here)?
E.g.

starknet-devnet --port 5001

or

starknet-devnet -p 5001

Or is it just a matter of convenience?

janek26 · 2022-01-05T09:52:49Z

I do use it personally.
But while integrating with ArgentX we also needed to set some default port for localhost we want the network to be on, and I just feel like 5000 is too often used (many devs use macOS). In that case the developer would need to spin up the local dev testate with the -p port option AND also change the port inside ArgentX. I think choosing a less frequently used port could resolve this

@janek26 I don't understand. Does your program run starknet-devnet in the background?

JorikSchellekens · 2022-03-10T13:00:51Z

@FabijanC Macos has a system service called ControlCe that uses port 5000 but the devnet doesn't error out properly when it uses that port. I don't know how this works - it looks like it's running fine but only handles a subset of the requests. It would be nice if the default port wasn't one used by Macos and that it would fail gracefully in this condition. For now just moving the port would save a lot of frustration, it took me a while to realise what was going on.

@JorikSchellekens
I agree that this should be done. The fact is, this is the only breaking change in the project backlog, and I don't want to release v0.2.0 just to change the default port. So, it should either be argued why the port change is sufficient for a new major version, or suggest another breaking change 😃 .

JorikSchellekens · 2022-03-10T13:40:57Z

@FabijanC
Considering that starknet-devnet doesn't work on a major os without any clear error messages as to why I'd say 0.1.0 is already broken.

JorikSchellekens · 2022-03-10T13:42:25Z

I've opened some prs for it which could wait until another breaking change comes along.
More importantly perhaps starknet-devnet should check the port is free and fail early, I can look into that later.

FabijanC · 2022-03-10T15:26:11Z

@ccarnino You said you'd like to be pinged on MacOS issues, did you also experience this issue with an occupied port? I'm asking because I'm not sure if all mac users are experiencing this. E.g. the CI/CD pipeline starknet-hardhat-plugin includes some integration tests that run Devnet on a mac virtual machine, and it works fine with the default settings.

clacladev · 2022-03-10T15:41:00Z

I personally have not experienced this problem, unless I was trying to run another devnet in another terminal by mistake.

@JorikSchellekens @janek26 what kind of issues or how do you realise that devnet is failing behind the scenes because of this issue?

JorikSchellekens · 2022-03-10T16:05:01Z

@ccarnino this is a monterey specific issue

I am on Monterey too. And I have the Airplay Receiver option On. I am running starknet-devnet from console, not from docker.

And no my test don't throw that error.

More importantly perhaps starknet-devnet should check the port is free and fail early, I can look into that later.

@JorikSchellekens Update us when you can, from what I've seen this should be fairly simple in Python with resources being a part of the standard library.
