Very slow when go.mod contains a new go version (go1.23) than in athens image (go1.22) - not caching

[chlunde]

Describe the bug
A clear and concise description of what the bug is.

Inside the athens container, the following command takes 40s when go.mod for github.com/org/repo uses go1.23:

wget http://localhost:3000/github.com/org/repo/@v/hash.info -O -

Downgrading go.mod to to go1.22.8 and updating the hash to that commit results in a 3 second response time.

There are probably three issues here:

• Quick fix: Upgrade athens to go1.23
• Probably (not confirmed): SDK is downloaded but not cached in /var/lib/athens (when using disk cache)
• When a new Go toolchain is used, /var/lib/athens is not updated (when using disk cache)

To Reproduce

module github.com/org/repo

go 1.23.2

Expected behavior

• Fast download second time a new SDK is used (Newer SDKs cached, and module cached)

Environment (please complete the following information):

• OS: [e.g. Linux 64bit]
• Go version : 1.22.8/1.23
• Proxy version : 0.5.4
• Storage (fs/mongodb/s3 etc.) : fs

Proxy version : 0.5.4
Storage (fs/mongodb/s3 etc.) : fs

just to clarify, do you mean v0.15.4 with disk StorageType?

Anyway, I am able to reproduce what you've encountered with go version 1.22.8 on Athens v0.15.4 using StorageType "memory" and "disk"), but not when i am using s3

have you had a chance to try this with other StorageTypes, like s3, mongo, minio, etc.? it would be super helpful if you could give that a shot too

To Reproduce

1. module fetched: curl -v http://localhost:3000/github.com/planetscale/cli/@v/v0.214.0.info (which has go 1.23.2 directive in its go.mod)
2. go version: go version go1.22.8 darwin/arm64
3. config.dev.toml: StorageType = "disk" or memory

i'm trying to narrow down if this only happens specifically for memory/disk storage type
