fix(backend): suppress no-versions warning for unresolved-latest backends by jdx · Pull Request #9548 · jdx/mise

jdx · 2026-05-02T16:51:19Z

Summary

Backends that opt into installing an unresolved latest selector (today only pipx for git-backed requests) legitimately return an empty remote version list when their source has no discoverable versions — e.g. a GitHub repo with no releases (only tags). The hard-error path was already addressed in #9401 by falling back to the unresolved selector.

What's still left is noise: every command that touches such a tool emits 3–12 repeated mise WARN No versions found for … warnings. The repetition comes from #9444 (don't cache empty version lists) — every separate call site that asks for remote versions in the same process re-fetches and re-warns. Underlying GitHub API calls are still deduplicated by RELEASE_CACHE, so this is purely log noise, not extra HTTP traffic.

This change suppresses the warning when the backend opts into unresolved_latest_version(). For those backends an empty list is the expected steady state, not an error worth flagging. Other backends still warn as before, so the warning continues to catch real problems (typo'd repos, configs pointing at the wrong place).

Refs #9381.

Reproduction

```toml

~/.config/mise/conf.d/tools.toml

[tools]
"pipx:a13xp0p0v/kernel-hardening-checker" = "latest"
```

a13xp0p0v/kernel-hardening-checker has 0 GitHub releases (14 tags). Before this PR:

```
$ mise current
mise WARN No versions found for pipx:a13xp0p0v/kernel-hardening-checker
mise WARN No versions found for pipx:a13xp0p0v/kernel-hardening-checker
mise WARN No versions found for pipx:a13xp0p0v/kernel-hardening-checker
pipx:a13xp0p0v/kernel-hardening-checker latest
```

After:

```
$ mise current
pipx:a13xp0p0v/kernel-hardening-checker latest
```

mise ls, mise outdated, and mise install are similarly quiet now.

Test plan

Manual repro with the discussion's tool — all warnings gone for mise ls, mise current, mise outdated, mise install
mise run lint
cargo build

Note

Low Risk
Low risk: only changes warning emission logic when a backend opts into unresolved_latest_version(), with no effect on version fetching or installation behavior.

Overview
Suppresses repeated No versions found warnings when list_remote_versions_with_info returns an empty list for backends that support installing an unresolved latest selector (via unresolved_latest_version()). Other backends still warn on empty remote version lists as before.

…ends Backends that opt into unresolved-latest installation (pipx git tools today) legitimately return an empty remote version list when their source has no discoverable releases (e.g. a GitHub repo with only tags). Skip the "No versions found" warning in that case so commands stay quiet for the intended steady state. Other backends still warn as before. Refs #9381

Greptile Summary

This PR suppresses the repeated No versions found for … warning when a backend opts into unresolved_latest_version() (currently only pipx for git-backed requests), where an empty remote version list is the expected steady state rather than a real error. The fix is a minimal, well-scoped three-condition guard; other backends continue to warn as before.

Confidence Score: 5/5

Safe to merge — single-line logic change with no behavioral impact on other backends.

The change is minimal (3 added lines), the opt-in is narrowly scoped (only git-backed pipx today), and the pipx unresolved_latest_version() already guards on PipxRequest::Git before returning Some, so PyPI-backed tools are unaffected. No data path, caching, or install logic is changed.

No files require special attention.

Important Files Changed

Filename	Overview
src/backend/mod.rs	Adds a third guard to the "no versions" warning: suppress it when the backend opts into `unresolved_latest_version()`, indicating an empty list is the expected steady state for that backend/tool.

Code Review

This pull request updates the version discovery logic in src/backend/mod.rs to suppress 'No versions found' warnings when an unresolved latest version is present. The review feedback suggests extending this logic to exclude BackendType::S3 from the warning as well, ensuring consistency with how Http backends are handled and reducing log noise.

gemini-code-assist · 2026-05-02T16:56:35Z

+                if versions.is_empty()
+                    && self.get_type() != BackendType::Http
+                    && self.unresolved_latest_version().is_none()
+                {


The check for BackendType::Http appears to be missing BackendType::S3, which is typically handled similarly in this module (e.g., line 723). Since S3 backends can also function without a remote version list (e.g., when using direct URLs), they should likely also be excluded from this warning to avoid unnecessary log noise.

Suggested change

if versions.is_empty()

&& self.get_type() != BackendType::Http

&& self.unresolved_latest_version().is_none()

{

if versions.is_empty()

&& !matches!(self.get_type(), BackendType::Http | BackendType::S3)

&& self.unresolved_latest_version().is_none()
