fix(upgrade): leave lazy tools that are not installed to their first run by ryanrhughes · Pull Request #14422 · jdx/mise

ryanrhughes · 2026-10-14T04:26:17Z

A bare mise install skips lazy tools, and since #14368 auto_update skips any tool with nothing installed. A bare mise upgrade still counted a lazy tool with nothing installed as outdated and installed it, so one mise up installed every lazy tool a config declares.

Now a bare mise upgrade leaves a lazy tool alone while no version of it is installed. It doesn't install the tool, list it in the note about versions outside the configured range, or warn about releases minimum_release_age holds back. Naming the tool still installs it, as mise install node does. A lazy tool with any version installed upgrades as before, and a missing lazy tool that an upgraded tool depends on is installed with it.

[tools]
claude = { version = "latest", lazy = true }
codex = { version = "latest", lazy = true }

Before: on a machine where neither has run, mise upgrade --dry-run prints Would install claude@… and Would install codex@…, and mise upgrade installs both. After: neither is mentioned or installed.

Found while testing omacom/omarchy#9596 on a fresh install. Omarchy declares 20 default tools this way, and omarchy update runs mise up, so the first system update would have installed all of them.

Changes

Upgrade::leave_missing_lazy removes a lazy request from a bare upgrade when the tool has no installed version. It then puts back any that a remaining entry depends on, using the same dependency declarations as the install graph. The out-of-range note and the minimum_release_age warning skip the same requests.
install_dependency_declarations and InstallDependencyDeclarations::matches are now pub, so the CLI can use them.
mise outdated marks a lazy tool with nothing installed as [MISSING] (lazy).
A bare mise upgrade --bump and the out-of-range note skip these tools too. A backend that fails to resolve is not treated as waiting for a first run, so its error still surfaces.
The lazy tools docs say what a bare mise upgrade does and what mise outdated shows.
New e2e/cli/test_upgrade_lazy_missing covers:
- a missing lazy tool in global and system config, --global, and a version range;
- naming the tool;
- an installed lazy tool upgrading, including when its request moves past what's installed;
- a tool that depends on a missing lazy tool;
- a missing non-lazy tool still installing;
- the release-age warning, using jq because the dummy backend has no release dates.
On mise 2026.10.9 the test fails at the first case.

mise outdated still lists these tools, since it reports state rather than acting on it, but now marks them so it is clear mise upgrade skips them:

claude  latest  [MISSING] (lazy)  …  /etc/mise/conf.d/defaults.toml

JSON output is unchanged.

Testing

On Linux:

These e2e tests pass: test_upgrade_lazy_missing, test_upgrade, test_upgrade_global, test_upgrade_latest_stale, test_upgrade_bump_multiple, test_upgrade_bump_keeps_prefix, test_upgrade_no_prune, test_install_before, test_lazy_tools, test_lazy_tools_depends, test_lazy_tools_system, test_lazy_tools_deferred_resolution, test_tool_update, test_tool_update_missing, test_tool_update_lazy_neighbors, and test_tool_update_global_auto.
The first commit's build fails the installed-request case. I checked the dependency case against that build and the warning case against 2026.10.9 separately: both behaved as the review comments describe.
cargo clippy --workspace --all-features --all-targets -- -D warnings is clean.
With Omarchy's 20 lazy declarations in /etc/mise/conf.d and an empty home, mise up reports "All tools are up to date" and installs nothing. mise upgrade codex installs codex.

unit-macos times out in shadow::tests::objects_at_finds_paths_across_several_git_calls, which times out on main at 5749c81 too. I haven't run the full unit or e2e suites, shellcheck, or shfmt, or tested on macOS or Windows.

Summary by CodeRabbit

Bug Fixes
- Running mise upgrade without naming a tool leaves missing lazy tools uninstalled, unless an upgraded tool depends on them. This also applies to global, version-range, and --bump upgrades.
- mise outdated marks missing lazy tools as [MISSING] (lazy).
- Naming a missing lazy tool in mise upgrade installs it. Bare upgrades continue to upgrade installed lazy tools, even when their current version falls outside the configured request.
- Missing lazy tools skipped by a bare upgrade are excluded from minimum release age warnings.

A bare `mise upgrade` counted a lazy tool with nothing installed as outdated and installed it, so one `mise up` installed every lazy tool a config declares. A bare `mise install` already skips them. Drop those from a bare upgrade and from its out-of-range note. Naming the tool still installs it, as `mise install node` does, and an installed lazy tool upgrades as before.

📝 Walkthrough

Bare mise upgrade skips missing lazy tools unless an upgraded tool depends on them. Explicitly naming a lazy tool can install it. mise outdated marks missing lazy tools as [MISSING] (lazy). Tests and documentation cover these behaviors.

Changes: Lazy tool upgrade behavior

Layer / File(s)	Summary
Filter missing lazy tools from upgrade checks `src/install_context.rs`, `src/cli/upgrade.rs`	Dependency declaration APIs are now public. Bare upgrades filter missing lazy tools unless they are explicitly selected or required by an upgraded tool. The command excludes skipped requests from out-of-range notices and minimum-release-age warnings.
Display and cover lazy upgrade behavior `src/toolset/outdated_info.rs`, `e2e/cli/test_upgrade_lazy_missing`, `docs/dev-tools/shims.md`	`mise outdated` displays `[MISSING] (lazy)` for uninstalled lazy tools. End-to-end tests cover selection, dependencies, non-lazy tools, and warning behavior. Documentation describes the install and upgrade behavior.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Suggested reviewers: jdx

Merge Risk: 🔵 Low · up to fc11f

Bare upgrades may still wait on or warn about backend lookups for lazy tools they will leave uninstalled. This bounded issue can be accepted for a follow-up; the bumped-request warning mismatch is fixed.

Summary

Bare mise upgrade leaves never-installed lazy tools for their first run, while keeping lazy dependencies needed by tools being upgraded.

Bare upgrades leave missing lazy tools alone unless another upgraded tool needs them.
Outdated lists mark missing lazy tools as [MISSING] (lazy).

_{Reviews (6) · Last reviewed commit: "Merge remote-tracking branch 'origin/mai..." · Reviewed by Greptile}

A lazy tool waits for its first run only while no version of it is installed, so changing an installed tool's request still upgrades it. A missing lazy tool that an upgraded tool depends on is installed with it, as before. A tool the upgrade leaves alone gets no minimum_release_age warning.

Filter missing lazy tools before outdated lookups.

When a bare upgrade includes a missing lazy tool, this line removes the tool only after the outdated check has queried its backend. A slow or failing backend can still delay the upgrade and emit lookup warnings for a tool that the upgrade will leave alone. Apply the lazy-tool exclusion when selecting candidates for the outdated check. Preserve candidates required by tools that will upgrade. (raw.githubusercontent.com)

Valid, but it needs a toolset-level change, so it's in a follow-up: #14444. A bare mise upgrade now defers resolution of missing lazy tools and skips their outdated lookup, keeping the ones an upgraded tool depends on.

🤖 Addressed by Claude Code

@jdx, thanks for the clarification. #14444 tracks the toolset-level fix, including dependency retention. This finding remains open for #14422 because the fix is in a separate PR.

Would you like a separate tracking issue, or is #14444 sufficient?
