zombienet: test parachain upgrades

[pepyakin]

one common thing that I have to do from time to time locally is testing that upgrading a parachain works. It would be great if that was automated away.

Currently, I am using this script currently to automate the process locally: https://gist.github.com/pepyakin/2583ff3348c0188dc3b25cf3537f5f70

Hi @pepyakin, Thanks for the gist! Let me work in the upgrade feature in zombienet and I will ping you to test.

Hi @pepyakin, I have an initial implementation here using the simple smoke-test as base. Can you send me an upgrade file to test since I tested locally with one generated by another zombienet instance and I get this error from the api

  zombie::network-node blockNumber : 10 +2s
2021-12-24 16:27:47        RPC-CORE: subscribeRuntimeVersion(): RuntimeVersion:: -32603: Unknown error occurred: Client, Application, VersionInvalid, RuntimeConstruction, Other, \"cannot deserialize module: InvalidMagic\

Thanks!

[pepyakin]

that's weird. Can you send me the file you are trying to send as an upgrade?

Do you have access to the built version of cumulus? If so, a valid wasm upgrade should be available target/release/wbuild/rococo-runtime/rococo_runtime.compact.compressed.wasm

[pepyakin]

Ah perhaps that's a bad idea, we should maybe modify the binary there to avoid having the same code hash, see paritytech/cumulus#863

[ordian]

Having same code hash would also make it harder to test upgrade succeeded.

Ah my bad, I was using the wasm generated by zombienet and not the one from cumulus. I will try with the right one and post the result here 👍.

update: Now the upgrade is ok but stop producing blocks.

@ordian / @pepyakin did you have a different config to test?

Thanks!

[pepoviola]

@pepyakin, upgrade test implemented in #4660.
Thanks!
