perf(go): speed up version discovery for modules with many releases - #13362
Conversation
`mise use go:mod@latest` listed every version of the module and then fetched a
release date for each one. On a module reached over VCS rather than a proxy —
any private module — each date is its own round trip, so a module with hundreds
of tags spent minutes there and usually hit the fetch timeout instead of
resolving at all.
Ask the module's route for `@latest` directly, the way `go install mod@latest`
does. That shortcut already existed for GOPRIVATE/GONOPROXY setups; it now also
covers modules reached through GOPROXY or over VCS, falling through from the
proxy to `go list` exactly as the version listing does.
When a full listing is still needed, cap how many versions get a release date:
the newest 100 through a module proxy, where dates are cheap concurrent
requests, and the newest 10 through `go list`, where each one is a VCS round
trip. Undated versions are already treated as installable by release-age
filters, so this only narrows how far back a `minimum_release_age` cutoff can
reach.
Measured against github.com/goreleaser/goreleaser (539 versions), cold cache:
GOPROXY=direct mise latest 20s timeout error -> 0.6s
GOPROXY=direct mise ls-remote 20s timeout error -> 9.0s
proxy mise latest 1.16s -> 0.12s
proxy mise ls-remote 1.33s -> 0.24s

The list this sorts has already dropped anything `Versioning` cannot parse, and go.dev/ref/mod#versions requires module versions to be semver, so nothing here falls back to arbitrary ordering. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The note scoped the dating cap to modules reached over VCS, which reads as if the default proxy route dates everything. It does not: it caps at the newest 100. Describe both caps and what each one means for a long `minimum_release_age` cutoff. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Go tools with hundreds of releases could time out during version discovery,
reporting
No versions found. mise fetched a release date for every version,which was especially slow when Go had to query VCS directly.
This change resolves
latestdirectly through the configured module proxy orgo list, extending the shortcut previously used forGOPRIVATEandGONOPROXYconfigurations. For example:When the latest stable release satisfies the configured release-age cutoff,
mise can select it without fetching the full version list. Private modules
still require the usual Go routing and VCS authentication.
Full listings, used by
mise ls-remoteand prefix requests such as@1, retainall versions but fetch release dates only for the newest 100 through a module
proxy or the newest 10 through
go list.Reported in discussion #13357.
Release-age limitation
minimum_release_ageallows versions with no known release date. If more than100 proxy versions or 10
go listversions fall within the configured agewindow, resolution may select an undated version that is newer than the cutoff.
This also affects
latestwhen its direct result is too recent and resolutionfalls back to the full list. The Go backend documentation explains this
limitation; #13364 addresses it in a
separate follow-up.
