@fzakaria:one.ems.hostfzakaria how do I go from Store to BinaryCacheStore21:55:59
@fzakaria:one.ems.hostfzakariathe config only return ref<Store>21:56:04

Sergei Zimmerman (xokdvium): writing a unit test for that issue you sent me is a bit harder because I think it's S3 specific (needs a store that uses query params)

For now I have https://github.com/NixOS/nix/pull/14266

One option: write a store just for tests that is simiilar to HttpBinaryCacheStore but sends the derivation path as a query parameter to test the encoding?

The S3 stuff is no longer relying on custom logic (since a couple hours ago) tho

@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Did that maybe just fix the issue entirely?23:39:01
@fzakaria:one.ems.hostfzakariait might have ; i included some change to src/libstore/binary-cache-store.cc that I think is "correct" but it doesn't have a unit test.23:39:42
@fzakaria:one.ems.hostfzakaria* it might have23:40:47
@fzakaria:one.ems.hostfzakariaAnyways; i pushed a unit test... took me a while to right. 🫠23:41:05
@fzakaria:one.ems.hostfzakaria* Anyways; i pushed a unit test... took me a while to write. 🫠23:41:09

@fzakaria:one.ems.hostfzakaria
