fix(install): keep incomplete-install markers out of the cache - #14051
Merged
Merged
Conversation
A version whose install never finished is marked incomplete so nothing selects it. The marker lived under MISE_CACHE_DIR, so `mise cache clear` or cache pruning deleted it and the half-done version then counted as installed. Markers now live in MISE_STATE_DIR/incomplete-installs; a marker an older mise left in the cache still counts. The tool-version lock keeps its old identity so old and new mise processes still share it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Entire-Checkpoint: 01M4AYDR22FEMVJ7VTVY5P96VP

Resolves conflicts with #14037: the postinstall token check now keys its lock on the tool-version lock identity, and the active-postinstall exception reads the marker through `is_incomplete`. Adds a one-time migration that moves markers an older mise left in the cache to the state dir, and `remove_by!`, a compile-time guard that fails the build at 2027.1.0 so the migration and the legacy-marker fallback get removed. The e2e test now also covers a failed postinstall hook and the migration. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Entire-Checkpoint: 01M4AZ93REQN3J7F34GF82X1HS

After the first migration writes .migrated, later processes stop checking legacy markers and skip the migration. If an older mise then leaves another failed install, newer mise lists and selects that unfinished version, even without clearing the cache.
Keep checking legacy markers throughout the compatibility window, and migrate newly created markers before clearing the cache.

An install that held the lock may have finished and cleared the marker while the migration waited; marking it incomplete again would hide a completed install. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Entire-Checkpoint: 01M4AZSXYQ0CH6XCTZTD93590T

all_moved to false and continue to later entries instead of propagating those
errors with ?. Preserve the existing behavior for successfully scanned
directories and unavailable locks.

skipped by the migration’s `LockFile::new(&legacy).try_lock()` path: preserve

Preserve skipped legacy markers during cache cleanup.
When an older installer holds the version lock, startup migration skips its legacy marker and does not write .migrated. A reachable mise cache clear node then removes the marker under CACHE/node while the version lock remains under CACHE/lockfiles; the install directory remains under INSTALLS. If the install is still in progress at the next startup, tool loading scans it before migration, and scan_versions can list it without the marker. The later migration can then write .migrated despite never moving that marker. Preserve skipped markers during cache clear and pruning until migration moves them under the version lock.

These tests simulated an interrupted install by writing the marker at the old cache path. Once a startup has migrated, that path is no longer read, so they now write where mise does. Clearing a marker also removes its version directory, so a second touch needs mkdir -p. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Entire-Checkpoint: 01M4B0YA7JTGFFAX07N4QVAQ8Z
A tool dir that cannot be read, or a lock that cannot be taken, now leaves that marker for a later run instead of aborting the migration. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Entire-Checkpoint: 01M4B0YC335FQXFM6XC19GRAN9

When an install doesn't finish, mise marks that version incomplete so nothing selects it until a later install repairs it. That covers an install that fails partway and, since #14037, a failed tool-level
postinstallhook. The marker was stored in the cache directory, somise cache clearor cache pruning deleted it. After that, the half-installed version counted as installed:mise ls --installedlisted it and fuzzy requests resolved to it.Here is how to reproduce it with
halfdone = { version = "1", postinstall = "exit 1" }configured and 1.0.0 already installed:With this PR,

Summary by CodeRabbit
Note
Medium Risk
Changes core install bookkeeping and version listing/selection; migration and legacy fallback reduce upgrade risk but behavior around incomplete installs affects many commands.
Overview
Incomplete-install markers no longer live under the cache. They are written to
$MISE_STATE_DIR/incomplete-installs/<tool>/<version>/incomplete, somise cache clear/ cache pruning cannot drop them and half-finished installs stay non-selectable.Call sites switch from per-backend
incomplete_file_pathtoinstall_state::{mark_incomplete,is_incomplete,clear_incomplete_marker}; uninstall and plugin purge explicitly remove markers. Startup migration moves any legacy cache markers into the state dir (respecting in-progress install locks) and recordsincomplete-installs/.migrated. Until that file exists, cache markers still count as incomplete.Tool-version lock identity stays on the old cache path so mixed old/new mise processes stay serialized.
remove_by!(plusversion_ltfor compile-time mise version checks) gates migration/fallback code for removal by 2027.1.0; AGENTS.md documents the macro.E2E and unit tests are updated for the new paths;
