Follow-up to #13362, now rebased onto main.

A tool version with no release date counts as old enough to install. That is the
right default for a backend whose source has no release dates at all, but it
means a backend that can only afford to date part of its listing quietly stops
honoring minimum_release_age
past that point — it will happily select an undated version that is in fact
newer than the cutoff.

#13362 introduced exactly that shape: dating a private Go module's versions
costs a VCS round trip apiece, so its listing dates only the ten newest (one
hundred through a module proxy). This makes the cutoff exact again without
giving that cost back.

What changed

Backend::fetch_version_created_at dates a single version. Before resolution
settles on a candidate that arrived undated, it asks for that one version's date
and moves further back while the answer says the candidate is newer than the
cutoff. The default returns None, so every backend that has no dates to give
behaves exactly as it does today.

The walk lives in list_versions_matching_with_selection_options, the shared
path behind latest, prefix and partial-version resolution — each of those
callers takes the last entry of the ordered candidate list itself, so the cutoff
has to be exact before the list is returned.

go: implements the hook through whichever route the listing used: a pass over
the module-path candidates against the proxy, then a pass through
go list -m -json mod@version. A private module under the default
proxy,direct GOPROXY is not on the proxy, so without that fall-through it
would be the one module class the hook could not date.

Dates read this way are remembered for the run, keyed by resolved backend and
version, so the second resolution does not repeat the round trips and the
"no versions found" message can still name the versions the cutoff hid. Only
answers are kept — "no date" is what an offline run or an unreachable source
reports, and holding onto that would leave a version unchecked.

Concretely

github.com/goreleaser/goreleaser has 539 versions; over VCS (GOPROXY=direct)
mise dates the newest ten, back to 1.21.2 (Oct 2023). With a cutoff older than
that, the boundary falls in the undated part of the list:

$ GOPROXY=direct MISE_MINIMUM_RELEASE_AGE=2023-06-01 mise latest go:github.com/goreleaser/goreleaser
1.18.2

1.18.2 is 2023-05-07 and the next release, 1.19.0, is 2023-06-28 — so that is
the newest version the cutoff allows. Before this change it returned 1.21.1,
released four months after the cutoff, because it was the newest undated entry
and nothing checked it. The same holds for a package path and for a prefix
request:

$ MISE_MINIMUM_RELEASE_AGE=2023-06-01 mise latest go:github.com/golang-migrate/migrate/v4/cmd/migrate
4.16.0

Cost and limits

  • Zero extra queries when the cutoff lands inside the dated part of a listing,
    which is where the 24h default lands.
  • One query per version the cutoff hides beyond it. The run above took ~30s
    cold, dating eleven versions one at a time over VCS. That is the price of a
    deep cutoff on a VCS-routed module; it was previously paid by being wrong.
  • A date that cannot be read at all is not fatal. The version is allowed, as a
    backend with no dates would be, and mise warns that it went in unchecked —
    one slow proxy should not turn a request that resolved before into an install
    error. A version can therefore still slip past the cutoff on a bad network;
    the go backend docs say so.
  • Verifying the version that gets selected is exact. Selecting the newest
    eligible version is best-effort: a backend whose version order is not
    chronological can stop on an older version than it strictly had to, which is
    the safe direction for a supply-chain cutoff.
  • Scoped to the shared fuzzy/latest resolution path. The npm semver-range path
    in tool_version.rs filters dates separately and is untouched.

Validation

  • eight new unit tests over the LatestBackend harness, covering: a partially
    dated listing skips an undated version the cutoff hides; the same for a prefix
    request; a backend that cannot date anything keeps today's behavior; versions
    the listing already dated are not re-queried; a known date is read once across
    two resolutions; a version that could not be dated is asked about again; a
    failing lookup allows the version instead of failing the resolution; and the
    remembered-date record evicts oldest-first
  • cargo test --bin mise — 4288 passed, 29 failed, all pre-existing sandbox
    failures in system::*, task::deps, tera and uv; none in backend::
  • cargo clippy --workspace --all-features --all-targets -- -D warnings,
    mise run lint
  • the commands above, against real modules over the network

📝 Walkthrough

Walkthrough

The backend now supports lazy release-date lookups for undated versions. Go propagates proxy and metadata errors. Version selection applies cutoffs to list and latest paths, memoizes successful dates, bounds memo growth, and tolerates failed lookups.

Changes

Go release-date filtering

Layer / File(s) Summary
Lazy date lookup contract and Go implementation
src/backend/mod.rs, src/backend/go.rs
Adds Backend::fetch_version_created_at. The Go backend queries proxy and Go metadata sources and returns lookup failures instead of treating them as missing dates.
Cutoff filtering and memoization
src/backend/mod.rs
Version selection lazily dates undated candidates for list and latest fallback paths. Successful dates use backend-specific keys and are evicted oldest-first after the 1024-entry limit. Failed or inconclusive lookups are not memoized.
Cutoff behavior tests and documentation
src/backend/mod.rs, docs/dev-tools/backends/go.md
Tests cover lazy dates, retries, failures, memoization, eviction, and already-dated versions. The Go documentation describes per-version date reads and unreachable sources.

Instruction counts

Nothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does.

New, nothing to compare against: env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, hook-env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, ls on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, registry on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, startup on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143

Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run.

A version with no release date counts as old enough to install. That is right
for a backend whose source has no dates at all, but it lets a cutoff lapse for
one that could only afford to date part of its listing: past that point
`minimum_release_age` stops hiding anything.

Add `Backend::fetch_version_created_at`, which dates a single version, and call
it before settling on a candidate that arrived undated — walking further back
for as long as the dates say the candidate is newer than the cutoff. The
default returns `None`, so a backend that genuinely has no dates keeps today's
behavior.

Implement it for `go:`, whose listing dates only the newest ten versions when
it has to reach the module over VCS. A cutoff deep enough to reach past those
ten now costs one query per version it skips instead of silently selecting the
first undated one.

Verifying the selected version is exact; selecting the *newest* eligible one is
best-effort, since a backend whose version order is not chronological can stop
on an older version than it had to. That is the safe direction for a supply
chain cutoff.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two gaps in the first cut of this change:

`fetch_version_created_at` only queried the module proxy when one was
configured, while listing and `@latest` both fall through to `go list` on a
proxy miss. A private module under the default `proxy,direct` GOPROXY is not on
the proxy, so the lookup reported no date — handing the cutoff exactly the
undated version it exists to check.

The cutoff walk only ran in `latest_version_for_query_with_selection_options`,
but prefix and partial-version requests resolve through
`list_versions_matching_with_opts` and take the last match themselves. Move the
walk into the shared matching path so every one of those callers gets it.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The cutoff walk propagated any error from `fetch_version_created_at`, so a
lookup that timed out — one network round trip per undated candidate, against a
slow proxy or VCS host — aborted the whole resolution. Requests that resolved
fine before the cutoff could be checked here at all would start failing on a
flaky network.

Allow a version whose date cannot be read, matching how a backend with no dates
at all is treated, and warn that it went in unchecked.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Three problems with the on-demand dating added here:

A version the walk dropped was invisible to `versions_hidden_by_before_date`,
which re-reads the cached listing where that version is still undated. Emptying
the candidate list therefore produced a bare "no versions found" instead of the
message naming what the cutoff hid and how to proceed. Remember the dates read
during a run so both the walk and that message can see them — which also stops
the second resolution in a run from paying for the same round trips again.

The Go lookup interleaved a proxy query and `go list` per module-path candidate
under one timeout, so a package path could spend the whole budget on `go list`
for a prefix that is not the module root, before the proxy was ever asked about
the path listing had already resolved. Run one pass per route instead, the way
listing and `@latest` do.

The docs claimed the cutoff "applies exactly", which overstates it: a date that
cannot be read at all allows the version with a warning. Say so.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The per-run record of on-demand release dates kept "no date" answers too. A
backend reports that for an offline run, a source it could not reach and
metadata it could not parse, so one transient failure left that version
unchecked against the cutoff for the rest of the process.

Keep only dates that were actually read. Those describe a release that already
happened and cannot change, so they stay safe to reuse; anything else is asked
again.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`fetch_version_created_at` folded a proxy that errored and a `go list` that
failed into the same `Ok(None)` as a version that genuinely has no date. The
cutoff walk cannot tell those apart: it took the version as checked and let it
past `minimum_release_age` without a word, which is neither what the docs
describe nor what `proxy_latest_stable` and `go_latest_stable` do with the same
proxy outcomes.

Keep the first real failure across both route passes and return it when nothing
produced a date. Only versions the listing already produced get here, so the
module does resolve, and nothing answering for it means something was broken
rather than undated — the caller then warns and allows the version, as
documented.

Also bound the per-run record of resolved dates. A CLI run cannot approach the
limit, but a daemon or embedded use would otherwise grow it without end, and
forgetting an entry only costs a repeated lookup.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`Backend::id()` is the registry shorthand, and one shorthand can resolve to
different backends. A date read for one of them would then be reused for the
same version of another, letting `minimum_release_age` judge a release it never
looked at. Key on `BackendArg::full()` instead.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Crossing the bound cleared the whole map, so one resolution could drop dates
another was still relying on to say which versions its cutoff hid. Drop the
oldest entry instead.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Rewrite the note around what this branch changes: a version with no release
date is now checked on demand rather than allowed, so the limits cost extra
queries instead of weakening `minimum_release_age`. The one case that still
lets a version through — a source that cannot be reached — keeps a warning of
its own.
