security(brew-cask): fingerprint an app target through the directory descriptor - #13294
Conversation
…ate root install_app took four positional booleans, two of which were both spelled `!cask.auto_updates` at the only call site, so the meaning of each argument was carried entirely by position. Bundle them into AppInstallOptions with named, documented fields. Also give the Caskroom path a named accessor, cask_state_root, so the root that holds mise's per-token install records is stated in one place rather than spelled inline.

Adds a macos-app package manager that installs a macOS .app bundle from a
declared URL, for apps with no Homebrew cask:
[bootstrap.packages]
"macos-app:nuvio" = { version = "1.1.20", url = "https://example.com/Nuvio-{{version}}-arm64.dmg", sha256 = "...", artifact = "Nuvio.app" }
mise already implements the cask installer natively, so macos-app is the same
installer with an inline declaration in place of Homebrew metadata: it reuses
the download, checksum verification, dmg/zip extraction, trusted-appdir swap,
and adopt semantics unchanged. BrewCaskManager now carries which manager it is
driving, in the same shape as FlatpakManager::new/new_user.
The two managers differ where they should:
- macos-app is macOS-only; brew-cask also serves Linux font casks
- macos-app supports version pins, because an inline url is a pin; a cask
exists only at its current version
- macos-app records ownership under mise's state directory rather than
Homebrew's Caskroom, so the two never contend for one token directory and
no non-Homebrew state lands in a Homebrew-shaped path
- the Homebrew ownership probe runs only for the manager that shares the
Caskroom

…d CLI specs Five defects found in review, all in the seam between the inline declaration and the shared cask pipeline. The declaration reached only `install_with_options`, so `installed()` and `upgrade()` still called `fetch_cask` and looked the token up in Homebrew — for the no-cask case this is exactly the lookup that fails, and status failing meant apply never reached the installer. Both now take manager options, mirroring `install_with_options`, and a single `resolve_cask` decides where metadata comes from. A macos-app request with no declaration is reported as a config error rather than sent to Homebrew. `packages_from_specs_with_config_files` likewise never attached the declaration, so `mise bootstrap packages apply macos-app:nuvio` could not build a Cask. It now resolves the entry from config and carries the pinned version onto the request. Also: - `ensure_homebrew_did_not_take_ownership` ran for every install, so a macos-app token that happened to exist in Homebrew's Caskroom failed after download despite the separate state roots - transaction journals were keyed `STATE/brew-cask/<token>` for both managers, letting one manager's pending or failed transaction hide or clean up the other's; they are now per-manager, and brew-cask's path is unchanged - `version` is joined into record and journal paths but was never validated, unlike fetched cask metadata, so a traversing version could place records outside the state root Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`no_check` is a Homebrew sentinel that makes the shared archive fetcher skip verification, for casks whose URL serves a moving target. An inline macos-app declaration names one pinned artifact, so accepting it there silently dropped the integrity check the manager documents as mandatory. AppSpec::parse now requires a well-formed 64-character hex digest, which also catches a truncated or mistyped one before the download rather than after. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
package_state consulted homebrew_installed_version before mise's own records, so a macos-app entry whose token also exists as a Homebrew cask reported Homebrew's version as its state — or failed the whole status query with a brew-cask error raised from leftover Caskroom metadata. The two managers keep separate state roots, so the probe now runs only for the one that shares the Caskroom, as it already does on the install path. Also label the linux platform-support error with the manager driving the install rather than always "brew-cask". Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
brew-cask avoids clobbering a Homebrew-owned app by checking whether Homebrew owns the token. macos-app cannot use that check, and the token is the wrong granularity anyway: /Applications is shared, and a declaration may name any bundle, so `macos-app:nuvio` can target an app a differently-named cask installed. Separate receipt roots keep install records apart but do not prevent a conflict at the app itself. macos-app now refuses to install over an app it has no record of owning, whatever installed it, and points at `adopt = true` to take it over in place. This is stricter than brew-cask's warn-and-replace on purpose: replacing a bundle strands the other owner's record and makes macOS revoke the app's Privacy & Security grants, which is the outcome adoption exists to avoid. The check runs before the download, so a conflict costs nothing, and before the dry-run return, so a plan reports it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…wnload The ownership guard ran before the archive was fetched, leaving the whole download window for Homebrew, another declaration, or a person to create the shared app target; activation would then replace a bundle that appeared in the meantime. install_app now carries the requirement and rechecks immediately before the swap, using the same fd-relative `exists_at` against the verified directory descriptor that the adopt path uses, so the check cannot be redirected by a replaced path component. Both call sites raise one shared error so they cannot drift apart. The early check stays: it fails fast and costs no download. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
mise_installed_cask_version returns None while a transaction journal is pending, so the unowned-app guard read an interrupted install as someone else's app: a crash or Ctrl-C after install_app had placed the bundle left the retry refusing with "not managed by this entry", and completing the install required deleting the app or setting adopt = true, for a leftover this entry created. A pending journal is positive evidence that this entry owns what is at the target, so requires_unowned_targets now consults it. Journals are per-manager, so a pending brew-cask transaction does not excuse a macos-app entry. The condition is extracted into one function that drives both the pre-download check and the swap-time recheck, so the two cannot disagree. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…acing it The previous commit treated any pending journal as proof this entry owned the app target. It is not: the journal is written before install_app, so an interruption during staging or preflight leaves one behind having created nothing. A retry then skipped both unowned-target checks and replaced whatever was at the path — including an app that appeared during the first download, or one installed by hand after the failure. That is the outcome the guard exists to prevent. The `app[..]` action is recorded only after install_app returns, so it is positive evidence that this entry placed the bundle. requires_unowned_targets now looks for that action rather than for a pending journal, which keeps an interrupted-after-placement install retryable without claiming a target this entry never wrote. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two findings in the last commit's predicate pull in opposite directions: a stale journal from an older version claims a target it no longer owns, and the window between install_app placing a bundle and record_cask_action recording it leaves an install unretryable. Both are inherent — a journal is written before the bundle exists, and the gap between placing one and recording it can never be zero — so no journal-derived predicate answers the question. The question is whether the bundle at the target is the one being installed, so ask that directly. install_app now compares the target against the staged artifact with cask_target_fingerprint, the same check adopt already uses: identical means this entry placed it (an attempt interrupted before its receipt landed) and the retry proceeds; anything else belongs to Homebrew, another declaration, or a person, and is refused. A receipt still short-circuits the whole check, so upgrades replace as before. This drops the journal-ownership machinery and the pre-download check, which could not compare content and so would have rejected exactly the retry this permits. Journals stay per-manager; they are no longer consulted for ownership. The accept path copies the bundle and so needs ditto; its test is macOS-only. The refusal path runs everywhere. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Treating a matching fingerprint as licence to replace was wrong: a swap revokes the app's TCC grants even when the replacement is byte-identical, because the grants follow the bundle's identity at the path rather than its content, and it strands the other owner's record if the bundle was not ours. The fingerprint says the content matches, not who put it there. So macos-app no longer swaps a bundle it holds no receipt for. An identical one is taken over in place, which completes an install interrupted before its receipt landed and stays safe when the bundle turns out to be someone else's copy of the same release, since nothing is moved, replaced or deleted. A differing one is still refused. A dry run has downloaded nothing to compare against, so it cannot tell the two apart. Rather than imply a clean install, it now warns that an app is already at the target and names both outcomes. The accept path returns before the copy, so it no longer needs ditto and its test runs everywhere rather than on macOS alone. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…dance Three CI failures and one review finding, all in what the last commit added. markdownlint rejected the new docs section for skipping a heading level, and prettier wanted the section reflowed. The Windows build failed because `app_fields` was only ever called from `#[cfg(unix)]` blocks, making it and the `url`/`sha256`/`artifact` fields dead there. The shape checks are now platform-independent, which is also the better behaviour: a config shared across machines should report a misplaced or incomplete declaration wherever it is read, not only where macos-app can run. Only the AppSpec parse stays unix-gated. The intra-doc link to the unix-only AppSpec is now plain text so rustdoc does not break on Windows. Finally, the docs and the dry-run warning told users `adopt = true` would take over a differing app. It will not: adopt requires no recorded version, which is the same precondition as the automatic in-place adoption, and auto_updates is always false for this manager so verification always runs. `adopt` therefore has no additional effect for macos-app. The messages now say to remove the app instead, and the docs say why adopt is meaningful for brew-cask but not here. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…ten schema `exists_at` finds the target through the verified directory descriptor, but both fingerprint comparisons then re-resolved it by pathname, so a component replaced after `ensure_trusted_appdir` could have them measure a different file from the one that was found. They now resolve through the descriptor. On linux that is fully bound via /proc/self/fd; on macOS F_GETPATH yields the directory's current path, so the binding is weaker there. This applies to the adopt comparison as well, which predates this PR and sits one line away from the new one — hardening only the new one would have read as an oversight. The schema now states the contract AppSpec::parse already enforces: url requires sha256, artifact and an explicit version via dependentRequired, and sha256 must be 64 hex characters, which also rejects Homebrew's no_check sentinel in an editor rather than at install time. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The shape checks were made platform-independent last round for a reason that applies equally to the field checks, but those stayed behind AppSpec::parse, which is unix-only. A macos-app entry with a malformed or missing checksum, artifact or version therefore passed unvalidated on Windows and was later discarded with a generic unknown-manager warning, diagnosing the wrong thing for a config shared across machines. The rules move into validate_app_declaration, which runs everywhere; only the AppSpec value, which nothing off unix consumes, stays gated. AppSpec::parse calls it, so there is one definition of what a valid declaration is. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…oads `app_fields` treated a value as present by Option alone, so `url = " "`, `artifact = " "` and a blank `version` all passed validation and failed later with a confusing error — a blank version is also joined into install-record paths. Blank values are now treated as absent: a blank url gets the "needs url, sha256, artifact and version" diagnosis, and blank artifact or version are rejected by name. A non-https url now warns rather than fails. `sha256` is mandatory and verified for this manager, so an http download is still integrity-checked, and an internal mirror over http is a real case for exactly the audience this feature serves. Refusing it would block them for no integrity gain. Not addressed here: mise's download client applies no redirect policy, so an https url that redirects to http is not stopped. `ClientKind::Fetch` has `fetch_redirect_policy` and `ClientKind::Http` does not, which affects every download in mise rather than this manager, and predates this PR. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two follow-ups to the previous commit. A padded value such as `version = " latest "` passed: the blank check trims, but the `latest` comparison does not, so the padded form was interpolated into `url` and joined into install-record paths. Padded versions are now rejected rather than trimmed, so the value that validates is exactly the value used — trimming would leave the validated and the on-disk forms free to diverge. The non-https warning also fired twice on unix, because the config loop called validate_app_declaration and then AppSpec::parse ran the same checks again. Off unix no spec is built, so the validator is called directly there and through AppSpec::parse everywhere else: one validation, one warning, on every platform. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two cosmetic issues found while validating macos-app on a real Mac. A dry run printed the declared app target rather than the resolved one, so a cask with an absolute target showed `link app /Applications/<name>.app` even when MISE_BREW_CASK_OPT_APPDIR relocates the install elsewhere — naming a path the install never touches. It now prints what app_target_path resolves. A refused install also left an empty `.mise-tmp-<hash>` directory under the manager's state root. The refusal happens before anything is staged, so the directory is removed with remove_dir, which fails on a non-empty directory and therefore preserves the partial state a genuine mid-install failure leaves for recovery. Neither is unit-testable here: the print goes through miseprintln, and the cleanup sits on the install path, which needs a real download. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The stack split looks sensible: #13278 isolates the mechanical cleanup, #13279 reuses the existing installer with separate state, and #13294 hardens fingerprinting while preserving receipt digests. I agree with accepting the documented residual same-user race rather than trying to make a mutable directory walk atomic. Before merging the feature, I would address these two ownership points in #13279 (posting here for the full stack): Blocker: replacement permission needs to be scoped to the app target, not just the package token. At the reviewed head,
The old receipt remains valid while Please require the current resolved target to appear in the previous ownership receipt before allowing replacement. An unrecorded target should go through the foreign-target policy even when the token has an installed version. Add regression coverage for both artifact-name changes and app-directory changes, asserting that an unrelated existing target remains untouched. Design decision: require explicit adoption of an existing identical app. Automatic in-place adoption preserves the bundle initially, but it creates overlapping ownership when Homebrew or another declaration already owns that app. A later mise version bump can then replace it while the other manager still claims it. After discussing this tradeoff, the requested policy is to refuse an existing unowned app by default and require explicit Document that adoption authorizes future mise replacements and that users should reconcile the other manager's ownership. For crash recovery, an identical bundle without a completed ownership receipt should follow the same explicit-adoption policy; a pending journal alone must not authorize takeover. This is a source-review finding against a39803f, not a locally executed reproduction. AI-assisted — Tool: Codex; model: openai/unavailable; version: unavailable. |
…plicit adopt Two ownership points from review of the stack. **Replacement was authorized by the token, not the target.** The guard was disabled whenever the token had an installed version, but the receipt records the paths it owned, not any path the declaration later names. Changing `artifact`, or changing the app directory, pointed the entry at a target no receipt covered while the stale receipt still made the token look installed — so an unrelated app at the new target would have been replaced. Ownership is now resolved per app against the previous receipt's `apps` and `metadata_only_apps`, and an unrecorded target goes through the foreign-target policy even when the package is installed. **Adoption is now explicit.** An identical bundle at an unowned target was taken over automatically. That creates overlapping ownership when Homebrew or another declaration still owns the app, and a later version bump would then replace a bundle the other manager believes it controls. `adopt = true` is now required to take over an existing app, and a differing bundle is still refused with it. This also gives `adopt` a meaning for macos-app, where it previously had no effect. An interrupted install is covered by the same rule: a bundle with no completed receipt needs explicit adoption, and a pending transaction never authorizes takeover. Docs state that adoption authorizes later replacements and that the other manager's record should be reconciled. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…descriptor install_app finds an existing target with fstatat against a verified directory descriptor and swaps through that same descriptor, but both fingerprint comparisons re-resolved it by pathname. A component replaced after ensure_trusted_appdir could have them measure a different tree from the one found and the one the swap touches. cask_target_fingerprint_at walks entirely through descriptors — fstatat, openat and readlinkat relative to the parent, recursing into child descriptors — so no pathname is resolved at any depth. This also covers the adopt comparison, which predates the macos-app work. Each open is confirmed to be the entry that was classified: O_NOFOLLOW refuses a symlink but not a same-kind replacement, so open_verified_at compares device and inode from the descriptor, as remove_staging_dir_at already does. Symlinks cannot be pinned this way — macOS has neither O_PATH nor AT_EMPTY_PATH — so read_link_verified_at re-stats after the read. That detects a replacement rather than preventing one, and is defeatable by renaming the original aside and back; what bounds it is open_trusted_directory refusing an app directory writable by anyone but root or the invoking user. The digest is unchanged, which is the constraint that matters: receipts record these, so a divergence would make every installed cask look modified. An equivalence test asserts both forms agree over nested and empty directories, an empty file, NUL bytes, a symlink, a dangling symlink, and names that sort differently as bytes than as path components. Rebased onto the target-scoped ownership change; the refusal path there needs no fingerprint, so only the adopt comparison uses these. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…llision The previous commit wrapped every activate_app_at failure as an unowned-target refusal and deleted both staged copies. That was wrong twice over: a brew-cask replacement failing for any reason was reported as "not owned by this entry", and a failure after the swap had already succeeded — where only the caskroom symlink was left — discarded the durable copy that path exists to keep. The collision now has its own error type. Only it triggers the cleanup, because only it means nothing was activated; every other failure propagates unchanged with both copies intact for recovery. Separately, when the no-replace claim succeeded but the rename after it failed, the empty placeholder directory stayed at the target, and a later apply would read it as a foreign app and refuse indefinitely. It is now removed on that path. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…urity/cask-fingerprint-descriptor-bound
Adding allow_replace to swap_app_at missed a call site inside a cfg(target_os = "macos") test, so the macOS build failed to compile while linux stayed green. The ACL repro replaces an app it owns, so it passes true; the no-replace path is covered separately. Swept every cfg(target_os = "macos") region in the cask tests for calls to the signatures changed in this branch. This was the only stale one — the AppInstallOptions literals in the other gated regions already carry the new fields. Caught by trusted / unit-macos. Cross-compiling to aarch64-apple-darwin fails in this environment on a zstd-sys C build, so macOS-gated code cannot be type-checked locally and that job is the only signal for it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…urity/cask-fingerprint-descriptor-bound
Instruction countsNothing 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: Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run. Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes.

…s' into feat/macos-app-manager
…tures main gained a prefetch pass (#13282) that decides which casks to download ahead of the serial install. It calls installed_versions and installed_skip_reason, both of which this branch changed: the first takes the manager, because install records are now per-manager, and the second takes the previous receipt, because ownership is per target rather than per token. Git merged the two changes without a textual conflict and the result did not compile. The prefetch now passes both, and treats an unreadable receipt the way the surrounding code treats an unreadable version — defer to the serial pass rather than guess.

The concurrent prewarm called fetch_cask directly, so for a macos-app entry it asked Homebrew about the token instead of reading the inline declaration. A token that also exists as a Homebrew cask meant downloading that unrelated archive, under brew-cask progress, before the serial pass fetched the declared vendor artifact. resolve_cask moves to a free function that both paths call, so the two cannot resolve differently. Prewarm now benefits macos-app rather than working against it: several declared apps download concurrently. The Homebrew ownership probe in the same loop is now gated on the manager that shares the Caskroom, matching the install path. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…al journals macos-app called prefix::bootstrap and locked $HOMEBREW_PREFIX/Caskroom, both of which create a Homebrew prefix this manager never writes to — on a machine without one that means elevating to create it, or failing outright, for records that live in mise's state directory. The bootstrap is now gated on the manager that shares the Caskroom, and the install lock lives in each manager's own state root. Separately, an unowned-target refusal left its transaction journal behind. A pending journal makes mise_installed_cask_version report not installed, so a later apply skips the already-installed fast path; if the declaration was reverted meanwhile, the original target is still owned, replacement is allowed, and an identical bundle gets swapped — revoking its Privacy & Security grants after a refusal that changed nothing. The journal is now removed when it records no completed actions, which is exactly the case where nothing durable happened. A failure after a hook or an artifact has run keeps its journal for recovery. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Prewarm now resolves macos-app declarations as well as casks, but its progress lines still said brew-cask, naming a manager the download has nothing to do with. The label comes from the resolved cask instead. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…urity/cask-fingerprint-descriptor-bound
Moving macos-app off the Caskroom lock fixed it creating a Homebrew prefix it never writes to, but left the two managers free to rename the same bundle in /Applications at once: separate records do not help when the resource being mutated is shared. A second lock, in mise's state directory, now covers every app-directory mutation and is taken by both managers and by prune. It is always acquired before the per-manager records lock, so the order is identical on every path. brew-cask's records lock returns to the Caskroom, so a concurrently running older mise still excludes it. Also gate prefix::bootstrap on the dry-run path. The real install stopped creating a Homebrew prefix for macos-app, but the preview still did, so on a machine without Homebrew `apply --dry-run` proposed work that applying would not perform.

…lled Three defects in the `macos-app` install path, all reported by Bugbot on #13279. An interrupted run leaves a pending transaction journal, which masks the receipt's recorded version. The next apply therefore skips the "already installed" check while the receipt still proves ownership, so the unowned-target refusal does not fire either, and the bundle is swapped. Replacing a bundle that already matches the staged artifact resets the app's macOS Privacy & Security grants for nothing — the exact harm this manager exists to avoid. An owned target whose contents are identical is now kept in place; one whose contents differ is still replaced. A `url` ending in `.git` was cloned rather than downloaded, so it never reached the checksum step. The declaration still required a 64-hex `sha256`, so a shared config could install an unverified bundle while looking checksum-pinned. Such a URL is now rejected, checked against the interpolated form because that is what the fetcher dispatches on. Staging directories were keyed only on token and version, so `brew-cask` and `macos-app` installing the same token at the same version could remove each other's extract tree and stage the wrong payload. Staging runs before the app-mutation lock, so the key now includes the manager, as install records already do. The downloaded archive needs no split: its name already includes a hash of the URL.

…riptor The identical-bundle check merged up from the layer below compared the target by pathname, which is what this branch exists to remove. Reuse the descriptor-bound fingerprint closures instead, so the comparison that decides whether to keep the installed app cannot be redirected by a component swapped after `ensure_trusted_appdir`.

…hip (#13298) The bootstrap packages overview mixed first-install instructions, manager selection, command reference, and detailed macOS ownership rules. Reorganize the entire page so readers can choose a manager, declare packages, and find the command they need, with direct macOS app downloads in a dedicated section. Stacked on #13294 (after #13278 and #13279). This PR changes only `docs/bootstrap/packages/index.md`, the stack's only modified Markdown file, and reviews the full page rather than only the newly added section. The revised app guide uses a multiline declaration with clearly identified placeholder download values and an architecture selector. It explains explicit adoption, future replacement ownership, interrupted-install recovery, and the unsupported prune operation. It also corrects two misleading claims: `upgrade` can apply a manually updated app declaration even though it cannot discover releases, and replacing a bundle may require renewed macOS permissions rather than invariably revoking every grant. The general guide clarifies cask self-updater adoption, configuration merging, platform selection, removal, and CI status checks. This is documentation only. The activation collision reported on #13279 remains a separate implementation issue. Validation: focused safe hk formatting/Markdown checks passed; all six TOML examples parse; all 55 internal links in the rendered article resolve, including fragment anchors. `mise run docs:build` passed, including eight social-image tests and image/metadata validation for 400 pages. *AI-assisted — Tool: Codex; model: openai/unavailable; version: unavailable.* <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > Documentation-only edits to the bootstrap packages guide and LLM index blurb; no runtime or CLI behavior changes in this diff. > > **Overview** > **Reorganizes** the bootstrap packages overview so readers follow a clearer path: quick start, host packages vs `[tools]`, manager table, declaration options, semantics, then command reference (apply/use, upgrade, where, import/prune), manager selection, sudo, and CI. > > **Moves and expands** direct **`macos-app`** guidance into its own section with a multiline placeholder declaration, field table, adoption rules, staging collision messaging, manual update steps, and an explicit note that **`macos-app` does not support pruning**.

Follow-up from review on #13279, stacked on it because it changes call sites that live there. Review #13278 → #13279 → this.
The problem
install_appfinds an existing app target withfstatatagainst a verified directory descriptor, and performs the swap through that same descriptor. Between those two, both fingerprint comparisons re-resolved the target by pathname.A component replaced after
ensure_trusted_appdircould therefore make the fingerprint measure a different tree from the one that was found and the one the swap will touch — so an app could be adopted, or refused, on the strength of contents that were never the target's. With a user-owned app directory (~/ApplicationsviaMISE_BREW_CASK_OPT_APPDIR) a same-user process can do that.#13279 routed both comparisons through
parent.path(), which is/proc/self/fdon Linux and fully bound, butF_GETPATHon macOS — a pathname, so macOS was left as it was. That is the platform this matters on.The change
cask_target_fingerprint_atwalks entirely through descriptors:fstatat,openatandreadlinkatrelative to the parent, recursing into child descriptors rather than joining paths. No pathname is resolved at any depth. Both comparisons ininstall_appuse it.This is not only the new manager's path — the
adoptcomparison it also covers predates #13279 and is howbrew-caskhas always verified an app before adopting it.The digest is unchanged, and that is the constraint that matters
Receipts on disk record these digests, so any divergence would make every installed cask look modified.
descriptor_bound_fingerprint_matches_the_path_based_oneasserts the two forms agree exactly over a tree containing:plus each kind at the top level, a missing entry erroring rather than digesting nothing, and a change to a nested leaf still moving the digest.
Tradeoff
The descriptor form always hashes in process, where the path-based form shells out to
sha256sumfor files above 50MB. The digest is identical either way; only that large-file shortcut is lost, and it cannot be kept without naming a path. App bundles do contain large binaries, so this costs some time on a fingerprint — it runs on adoption and on the unowned-target check, not on an ordinary install.The path-based
cask_target_fingerprintstays, for callers that hold no descriptor.Validation

cask_shim_*tests fail on the dev machine for lack of Ruby and fail identically onmain.The equivalence test runs on Linux, which is what makes this change checkable at all — the digest agreement is filesystem behaviour, not platform behaviour. What CI cannot reach is the same thing as in #13279: an actual app swap on macOS. The manual plan used to validate that PR covers the adopt and refuse paths this touches, and is worth re-running on a Mac before merging.

Overview
Adopt and keep identical bundle checks in
install_appno longer fingerprint the on-disk app by re-resolving a pathname (including macOSF_GETPATHfrom the verified appdir fd). They now callcask_target_fingerprint_at, which walks the tree withfstatat/openat/readlinkatrelative to the same directory descriptor used forexists_atand the swap, so a same-user swap of a path component mid-check cannot compare or adopt against a different tree than the one being installed.The new implementation lives in
state.rs: descriptor walks with inode rechecks after classify/open/readlink (open_verified_at,read_link_verified_at), in-process file hashing (replacing the path-basedsha256sumshortcut for large files), anddigest_from_entriesaligned with existing receipt digests.cask_target_fingerprintremains for callers without a fd.Tests assert byte-for-byte digest parity with the path-based fingerprint and that post-classification replacement of directories/symlinks fails closed.
