install: re-resolve a dependency that bun.lock binds outside its range, and fail --frozen-lockfile on it - #48557
A merged bun.lock can bind a package's dependency outside its range: make-dir@4.0.0 needs semver ^7.5.3, its make-dir/semver row is gone, and the row binds to the root's semver@6.3.1. --frozen-lockfile exits 0 and bun install reports no changes.
The loader binds rows by name with no range check (find_resolution, bun.lock.rs). The differ checks root and workspace rows only, rows_outside_overrides only rows that a rule names.
Fix
rows_outside_ranges checks every row against its effective range: the rule that applies, else the catalog entry, else the declared range. bun install resolves such a row again. Rows that shared its old package stay.
Self-reviewed: 13 concerns raised, 9 addressed. Rejected: a frozen exemption per applied rule, and rows bound to a workspace or tarball copy (Notes).
Downsides
A committed bun.lock with such a row fails --frozen-lockfile until bun install repairs it.
Every install with a lockfile runs the scan: 2,647 rows for test/bun.lock, one rule probe, one name compare and one satisfies per row, no allocation. No perf or valgrind here, so instructions are not measured.
Release bun_install rlib: text +2,928 bytes, data +120 bytes.
Notes
Reproduced on main 89452d2ac13 (debug build) and Bun 1.4.3 with the report's steps: bun install --lockfile-only, delete the make-dir/semver row, bun install --frozen-lockfile exits 0, bun install prints Checked 2 installs across 3 packages (no changes), node_modules/make-dir/node_modules/semver does not exist.
npm ci rejects the same edit of package-lock.json (Missing: semver@7.8.6 from lock file), and npm install restores the nested entry.
The leaf of the check, dedupe::version_outside_range (same name, not an empty or * range, satisfies), is shared by the differ's locked_version_is_out_of_range and the scan.
Why peer and optional rows without a rule stay: a peer takes the installed version when none fits its range, and an optional row that never resolved loads bound to a copy of its name. bun add no-deps@1.5.0 on a peerDependencies entry, with 1.5.0 unpublished, keeps the installed 1.1.0 and warns. The scan must not undo that. The "keeps the installed copy" tests in bun-update-transitive.test.ts cover it.
The other exemptions are the ones the override check had: bundled rows, optional peers, a row that follows an npm: alias under another name, an empty or * range (resolves to latest, which can be a prerelease), a name in two dependency groups, and yarn's reading of resolutions in a migrated lockfile.
Not covered: a row bound to a workspace, tarball or git copy of its name (resolution tag other than Npm). The same merge can leave one. A fresh resolve links a range to a workspace only when the version fits, so the binding is stale, but re-resolving it sends the name to the registry, and a private workspace name fails there. That is a separate change with its own rule per resolution tag.
The differ's locked_version_is_out_of_range keeps its prerelease exemption and its name-level rule exemption. The scan after the clean checks every row with the shared leaf, so a direct row bound to a prerelease outside a range that is not * is refused by the scan, with the scan's note. The resolver takes latest only for an empty or * range, or when the range accepts it, so such a binding is stale.
redirect_moved_edges is what bun update <name> and a rule use: every row that shared the old package follows when its range accepts the new one. For a row that only its own range moved, that pulled the root's own row down (no-deps ^1.0.0 locked at 1.1.0 followed a repaired one-fixed-dep/no-deps@1.0.0). The repair now passes only the rows a rule applies to.
warn_orphaned_patches ran before the scan and reported the patch for the version that the repair brings back as orphaned. It runs after the scan now.
The !dry_run gate on the re-resolve dates from install: consolidate the open package manager pull requests #44968, where it was chained to the package.json write-back. bun pm fetch sets dry_run, so it fetched two packages for the stale lockfile and bun install --offline then failed on the missing manifest. Nothing in the re-resolve writes: Do::SAVE_LOCKFILE is off under dry_run and the security scanner returns early.
A lockfile that Bun 1.4.3 wrote with a range that main's semver parser reads differently (>x, which 1.4.3 read as everything) is the one way to hit the frozen failure without an edit.

…range, and fail --frozen-lockfile on it
The post-clean check that resolved a row outside its overrides rule
again now checks every row against its effective range: the rule that
applies to it, else its catalog entry, else the range it declares. A
merged or edited bun.lock that binds a package's dependency to a
hoisted copy outside that range is repaired by bun install, and refused
by --frozen-lockfile and bun ci with a note that names the row. Rows
that a rule names keep the frozen exemption for lockfiles that Bun 1.4
wrote. Peer and optional rows without a rule stay as the resolver leaves
them.
…lace, and run the scan under --dry-run
The leaf of the check (same name, not an empty or * range, satisfies)
moves to dedupe::version_outside_range, which the differ's
locked_version_is_out_of_range and rows_outside_ranges both call. A row
that only its own range moved no longer drags the rows that shared its
old package along through redirect_moved_edges: only a rule does that.
The scan runs under --dry-run and bun pm fetch, which write nothing.
warn_orphaned_patches runs after the scan, so a patch for the version
that a repaired row brings back is not reported as orphaned.
Install now detects dependency resolutions outside applicable ranges. Non-frozen installs re-resolve eligible rows, while frozen installs report a rejected row. The change also adds lockfile range checks and CLI tests for both linkers.
Changes
Out-of-range lockfile resolution
Layer / File(s)
Summary
Shared range validation src/install/dedupe.rs, src/install/lockfile/Package.rs
A shared predicate checks whether an npm resolution satisfies its applicable range. Lockfile validation calls this predicate and retains guards for peer, optional, prerelease, and override cases.
Out-of-range row selection and re-resolution src/install/PackageManager/install_with_manager.rs
The install flow identifies rows outside effective ranges and filters rows whose lockfile bindings should remain. Edge redirection now applies only to moved rows with an override.
Frozen and non-frozen install outcomes src/install/PackageManager/install_with_manager.rs
Non-frozen installs re-resolve eligible rows. Frozen installs report a recorded out-of-range row when no changed section explains the failure. Orphaned-patch warnings run after row handling.
Tests cover stale lockfile entries with hoisted and isolated linkers, frozen and dry-run behavior, plain-install repair, patch placement, and accepted peer and override cases.

Severity of issue fixed: Medium
Merge Risk: Moderate · up to c0845
Frozen installs may accept a lockfile whose root catalog row resolves outside its declared range. Regular installs may also re-resolve some peer or optional rows that no override applies to. Resolve both before merging; the remaining test-assertion gaps are minor.

Full details: Linked Issues check
Explanation
Issue #48528 requires rejection of a lockfile row that binds a package dependency outside its range, repair during regular install, and retention of the root package. The implementation scans rows using the effective override, catalog, or declared range. Frozen installs record and report the first non-rule row outside its range. Regular installs re-resolve those rows and redirect only rule-driven rows. The added tests cover frozen install, bun ci, dry-run output, both linkers, nested resolution, root resolution, and patch placement.
Full details: Out of Scope Changes check
Explanation
The changes stay within the linked issue scope. The shared range predicate, frozen-lockfile flow, re-resolution behavior, edge-redirection correction, orphaned-patch ordering, and tests directly support stale dependency-row handling. Peer, optional, override, catalog, and linker cases validate required lockfile behavior. The description identifies workspace, tarball, and git bindings as excluded follow-up work, and the reviewed changes do not add unrelated functionality.

Preserve the stale root row for frozen validation.
If a root catalog: row points outside its range and a compatible version is already loaded under an alias, resolution can reuse that version and redirect the original row. The frozen scan and equality check can then accept the repaired binding instead of rejecting the committed lockfile.
Preserve the original rejected row before resolution and use it for frozen validation.

Require an applied rule before moving a peer or optional row.
If a scoped override names a package only under one owner, has_rule_for_name also admits that package's peer or optional row under another owner. That row has no applied override. If no other row holds its out-of-range package, retain_rows_to_resolve_again keeps it and a regular install re-resolves it. Use applied_override(lockfile, row as DependencyID, dependency).is_some() for this gate.

Assert the package’s peer binding.
The root pin can satisfy pinned even if peer-deps-fixed uses a separate in-range version. Assert that its lockfile peer binding resolves to no-deps@2.0.0 and that the package loads that version. This ensures the test exercises the peer exception.

Beyond the inline findings, I also checked the differ refactor in src/install/lockfile/Package.rs (locked_version_is_out_of_range now delegating to dedupe::version_outside_range) for behavior drift: the added empty/* range guards are no-ops there because * satisfies every non-prerelease version and prerelease pins are already excluded by the kept has_pre() check, and the ResolutionTag::Npm test still precedes the .npm() call. The re-resolve under --dry-run was also examined and ruled out as a regression, since the dry run writes no lockfile and the test asserts that.
Not run here: the REVIEW.md checks that need a build or test run (that deleting each clause of the fix breaks a test, and the suites listed in the PR notes).
Extended reasoning...
The change touches the Rust package manager's post-clean lockfile scan in src/install/PackageManager/install_with_manager.rs, extending the override-only range check to every dependency row, adding a --frozen-lockfile refusal path with a new note, moving the orphaned-patch warning after the re-resolve, and sharing a new dedupe::version_outside_range leaf with the lockfile differ in Package.rs; it touches no auth, crypto, or injection surface. Seven inline findings were posted (frozen-lockfile regressions on migrated or older-Bun lockfiles, a misleading summary line, a lost patch warning under a fatal scanner, and remaining gaps for optional and npm-alias rows), so a human look is already signalled; this body only records the differ refactor and dry-run re-resolve as examined and ruled out by reading.
Findings marked 🟡 are optional suggestions and need no follow-up push.
Additional findings (outside the current diff — GitHub can't attach inline comments there):
🟡 src/install/PackageManager/install_with_manager.rs — Users whose bun install repairs a stale transitive row see a summary line claiming their direct dependency moved, e.g. ↑ no-deps 2.0.0 → 1.1.0, while the root's no-deps@ 2.0.0 is still installed. install_with_manager.rs:2633 passes every repaired row to enqueue_peer_rows, whose register_moved records the row's old package as the original of the whole name. The old package stays, because by_rule now keeps sibling rows on it, so print_transitive_updates reports the new nested copy as an update of the name. Fix: register as moved only the rows a rule moved (the by_rule set) or report self-range repairs with their own wording, so a repair never prints an update row for a package that is still installed; the frozen note and the dry-run listing are unaffected.
Why this was flagged
Trigger: the test's first shape, root pins no-deps 2.0.0 and one-range-dep@ 1.0.0 needs no-deps ^1.0.0, with the one-range-dep/no-deps row deleted from bun.lock, then a plain bun install. reresolve_rows_outside_ranges pushes the row with its old package into moved at install_with_manager.rs:2629-2630 and calls enqueue_peer_rows at install_with_manager.rs:2633. enqueue_peer_rows always runs update_transitive.rs:466-469, so register_moved stores no-deps with original 2.0.0 in updating_packages. The root's row is not redirected, since by_rule at install_with_manager.rs:2643-2652 excludes rows no rule names, so no-deps@ 2.0.0 remains the root's resolution. print_transitive_updates (tree_printer.rs:473-509) finds the newly installed nested no-deps@ 1.1.0, which is not a root target, and original 2.0.0 != 1.1.0, so it writes ↑ no-deps 2.0.0 → 1.1.0. On the base branch only override rows reached this code and redirect_moved_edges moved every row of the name, so the old package was gone and the row was accurate. The new test only asserts stderr and never checks stdout, so it does not catch this.
Verification: nit — triggered whenever a plain bun install repairs a row that only its own range moved while another row keeps the old package. reresolve_rows_outside_ranges pushes the row into moved (install_with_manager.rs:2629-2630) and enqueue_peer_rows calls register_moved (update_transitive.rs:466-469); the by_rule filter at :2643-2652 keeps the old package, so print_transitive_updates prints ↑ no-deps 2.0.0 → 1.1.0. The PR's test does not assert on plain.stdout.

🔴 If any team migrates a yarn.lock whose bindings a hook or an unsupported resolutions pattern placed outside the package.json range, bun install --frozen-lockfile now exits 1 where the base installed it. rows_outside_ranges at install_with_manager.rs:707 flags every row with no rule, and first_row_frozen_refuses at :714 refuses it; only the yarn tolerance in retain_rows_to_resolve_again at :2502 is exempt. Fix: skip the frozen refusal (or treat as the base did) for rows a migrated lockfile bound, i.e. when load_result.migrated_from() is Some, for every migration source.
Why this was flagged
Trigger: bun install --frozen-lockfile on a repo whose lockfile is migrated from yarn.lock (the frozen path accepts migrated lockfiles, install_with_manager.rs:871-874 notes them). pnpm's readPackage hooks and yarn's packageExtensions/nested resolutions keys leave a dependency bound to a version outside the range the dependent's manifest declares, with no overrides rule Bun reads (pnpm.rs:1790 copies only pnpm.overrides; migration.rs:306 reads only overrides/resolutions). The scan at install_with_manager.rs:707 applies version_outside_range (dedupe.rs:745) to every such row; has_rule_for_name (OverrideMap.rs:452) is false, so first_row_frozen_refuses (:2569) returns it and the install crashes at :867. The base branch only scanned rows that an override rule named, so these installs passed. The finder could not size it; the population is every migrated monorepo with a hook, which the checkout cannot rule out. Remedy: exempt rows of a migrated lockfile from the frozen refusal, or gate the refusal on the lockfile being Bun-written.
Verification: Triggered when a yarn v1 yarn.lock is installed with --frozen-lockfile and a resolutions rule that Bun does not translate bound an entry. rows_outside_ranges (install_with_manager.rs:2457-2486) no longer requires has_rule_for_name; first_row_frozen_refuses returns the row. On the base, the same row never reached the scan, so --frozen-lockfile on that yarn.lock installed.
The reason will be displayed to describe this comment to others. Learn more.
🟡 (optional) Teams whose committed lockfile was written by an earlier Bun can see bun ci / --frozen-lockfile exit 1 after upgrading, with no package.json or lockfile edit, where the base passes. The frozen refusal in first_row_frozen_refuses (install_with_manager.rs:2569-2573) exempts only rule-named rows; any transitive row bound to a version that main's satisfies rejects is refused, including rows in bun.lockb, which no merge can rebind, so there every refusal is of a binding Bun itself wrote. Fix: limit the frozen failure to the condition the purpose targets (a bun.lock row the loader rebound through a missing nested entry), or warn rather than fail for rows a previous resolver could have produced.
Why this was flagged
A project has a committed bun.lock or bun.lockb written by an earlier Bun whose semver reader accepted a transitive dependency range differently from main (the PR itself names >x, which test/cli/install/semver.test.ts:961-998 shows main now reads as satisfied by nothing). CI runs bun ci or bun install --frozen-lockfile on the new Bun. rows_outside_ranges (install_with_manager.rs:2457-2486) flags the row because dedupe::version_outside_range (dedupe.rs:746-763) applies main's satisfies to the recorded binding, and first_row_frozen_refuses (install_with_manager.rs:2569-2573) exempts only rows whose name an overrides rule names. The frozen block at install_with_manager.rs:803 then skips the Lockfile::eql acceptance and prints lockfile had changes, but lockfile is frozen plus note_row_outside_range, then Global::crash() at 867. On the base branch the frozen check compares only root and workspace rows to package.json, so the same lockfile passes.
Verification:first_row_frozen_refuses in src/install/PackageManager/install_with_manager.rs (lines 2565-2573) exempts only rows where lockfile.overrides.has_rule_for_name(...); there is no tolerance for a binding an earlier Bun wrote. On the base, this path only existed for rule-named rows and was additionally gated by !dry_run && !is_frozen, so the base passes bun ci on the same lockfile.
The reason will be displayed to describe this comment to others. Learn more.
🟡 (optional) Users running bun install with a security scanner that fails the install no longer see the orphaned-patch warning the base printed before resolve. warn_orphaned_patches moved from before clean_lockfile to install_with_manager.rs:744, after run_security_scanner at :730, which can exit the process. Fix: keep the warning reachable on every exit path of the resolve step, e.g. print it before the scanner runs but after reresolve_rows_outside_ranges, or compute the orphan list before the scanner and emit it after.
Why this was flagged
Trigger: a project with a patchedDependencies entry whose version is no longer in the lockfile and a configured security scanner (manager.options.security_scanner.is_some()) that returns a fatal advisory. On the base branch warn_orphaned_patches ran right after clean_lockfile (old :680-682), before the scanner, so the warning always printed. In the diff it runs at install_with_manager.rs:744, after run_security_scanner at :730-738, which prints advisories and exits; the warning is lost on that path. Seven finders raised it and let it go as advisory; the population is every install with a scanner and a stale patch, at every install. Remedy: emit the warning before the scanner (after the re-resolve) so a repaired row's patch is still excluded.
Verification: Trigger: a root patchedDependencies key whose version is no longer in the lockfile, plus a security scanner that returns a fatal advisory. On the base, warn_orphaned_patches ran directly after clean_lockfile. In the PR it moved to install_with_manager.rs:744-747, after run_security_scanner at :730, which terminates the process with Global::exit(1) at :2717, so the warning is never printed.

🟣 pre-existing, not blocking: pre-existing: a merge that binds a package's optionalDependencies row to the wrong version still passes --frozen-lockfile and bun install still reports no changes. install_with_manager.rs:2470-2471 drops every is_optional() row that no rule names before the range test, and the differ at Package.rs:1862 skips them too. Fix: scan a bound optional row like a dependency row (keep the peer and never-resolved exemptions), since the loader already leaves never-resolved optional rows at invalid_package_id (bun.lock.rs:3029-3031); the stated reason for the exemption only holds for lockfiles without the "unresolved" list. Exact-pinned optional platform binaries (esbuild, sharp, swc, rollup) are the commonest real shape of issue #48528. A small fix can ride a push you are already making; otherwise a short reply is enough.
Why this was flagged
A bun.lock merged from two branches keeps esbuild@ 0.21.5 but the entry "@ esbuild/linux-x64": ["@ esbuild/linux-x64@ 0.20.2", ...]; the row esbuild -> @ esbuild/linux-x64 0.21.5 (an optionalDependencies row) is bound by the loader's name walk to the 0.20.2 package. rows_outside_ranges at install_with_manager.rs:2470-2471 excludes the row because dependency.behavior.is_optional() is true and lockfile.overrides.has_rule_for_name is false, so version_outside_range (dedupe.rs:746) is never run on it. first_row_frozen_refuses at install_with_manager.rs:2569 therefore returns None and bun install --frozen-lockfile / bun ci exit 0; a plain bun install re-resolves nothing and prints no changes; esbuild then fails at runtime with its version-mismatch error. The base branch behaves the same (the differ at src/install/lockfile/Package.rs:1862 also skips optional rows), so this is a path the partial fix leaves open.
Verification: pre-existing. A merged bun.lock keeps a package whose optionalDependencies row is bound by the loader's name walk to a package of another version. src/install/PackageManager/install_with_manager.rs:2470-2471 drops every optional row that no override names before version_outside_range runs, so --frozen-lockfile exits 0. The differ at src/install/lockfile/Package.rs:1862 skips the same rows.

🟣 pre-existing, not blocking: pre-existing: a merged bun.lock that rebinds a package's dependency to an npm: alias of another package still passes --frozen-lockfile and bun install reports no changes. src/install/dedupe.rs:757 returns false when the bound package's name differs from the range's npm name, so the new scan never lists the row. This is the #48528 shape whenever the nearest surviving key of that name is an alias (root "react": "npm:@ preact/compat@^17" with a transitive react@^18 row), or an alias row rebound to a plain package. Fix: in rows_outside_ranges, count a bound package whose name is not the one the effective range names as outside (both directions), while keeping rule-named rows on their existing frozen exemption. A small fix can ride a push you are already making; otherwise a short reply is enough.
Why this was flagged
Root package.json has "react": "npm:@ preact/compat@^17" and depends on some-lib, whose manifest declares "react": "^18". A fresh install writes keys "react" (package @ preact/compat@ 17.x) and "some-lib/react" (react@ 18.x). A merge drops the "some-lib/react" entry. On load, src/install/lockfile/bun.lock.rs:1604 walks up by key only and binds the some-lib row to the "react" entry. In src/install/PackageManager/install_with_manager.rs:2473-2482 the row reaches version_outside_range with npm.name "react"; src/install/dedupe.rs:757 compares "react" to "@ preact/compat", is false, and short-circuits before satisfies. The row is absent from outside, so install_with_manager.rs:714 leaves frozen_refused_row None and install_with_manager.rs:715 never re-resolves it. bun install --frozen-lockfile exits 0, bun install prints no changes, and some-lib loads @ preact/compat as react. The base branch fails the same way (its scan only looked at rule-named rows).
Verification: pre-existing (the base's override-only scan never reached this row either). Trigger: a bun.lock whose nearest surviving key for a plain-range row is an npm: alias entry of another package. src/install/dedupe.rs:757 npm.name.slice(range_buf) == name.slice(resolution_buf) is false, so version_outside_range returns false and rows_outside_ranges never lists the row; --frozen-lockfile exits 0.

🟣 pre-existing, not blocking: CI users whose package.json holds any scoped rule for a name (foo>no-deps) still get the wrong version installed under --frozen-lockfile when a merge rebinds an unrelated row of that name outside its range. first_row_frozen_refuses at install_with_manager.rs:2569 exempts by has_rule_for_name, which is true for scoped rules that do not apply to the row, so the detection the PR adds is silently off for that whole name. Fix: exempt only rows that applied_override reports a rule for, and refuse the rest, so sibling rows the rule does not select are checked like any other row. A small fix can ride a push you are already making; otherwise a short reply is enough.
Why this was flagged
Trigger: package.json overrides contains foo>no-deps: 2.0.0; a merge removes the one-fixed-dep/no-deps row so its no-deps 1.0.0 edge binds to root no-deps@ 1.1.0; bun ci runs. rows_outside_ranges (install_with_manager.rs:707) lists the row because applied_override finds no rule for it and version_outside_range (dedupe.rs:745) is true. first_row_frozen_refuses (:2569) then checks has_rule_for_name (OverrideMap.rs:452-454), which includes scoped_names, so the row is exempt and frozen_refused_row stays None; the install exits 0 with no-deps@ 1.1.0 where 1.0.0 was asked. The author says the name-level exemption is for Bun 1.4 lockfiles that disobeyed a rule; the sibling case here is a row no rule selects. A plain install does re-resolve it (:715), so frozen and non-frozen disagree for this population. Remedy: exempt a row only when applied_override(lockfile, row, dependency) is Some (as reresolve_rows_outside_ranges already does at :2645).
Verification: Pre-existing: the base never checks any row under --frozen-lockfile; this change does not reach names that a scoped rule targets, so merging makes nothing worse. Acknowledged in diff: the doc comment on first_row_frozen_refuses (src/install/PackageManager/install_with_manager.rs:2561-2564) says "The name is enough", so the trade-off is deliberate, but no test pins the scoped-rule shape.

Fixes #48528
Problem
bun.lockcan bind a package's dependency outside its range:make-dir@4.0.0needssemver ^7.5.3, itsmake-dir/semverrow is gone, and the row binds to the root'ssemver@6.3.1.--frozen-lockfileexits 0 andbun installreports no changes.find_resolution,bun.lock.rs). The differ checks root and workspace rows only,rows_outside_overridesonly rows that a rule names.Fix

Rows that shared its old package stay.--frozen-lockfileandbun cifail withnote: bun.lock resolves semver ^7.5.3 of make-dir@4.0.0 to semver@6.3.1.

bun.lockrecords placements, not ranges, so a missing nested entry rebinds the row in silence.bun.lockonly. A first-wave scan (install: re-resolve a dependency that bun.lock binds to a package it does not accept #43375) needs reachability and alias fixpoints.Downsides

The scan must not undo that. The "keeps the installed copy" tests inbun-update-transitive.test.tscover it.npm:alias under another name, an empty or*range (resolves tolatest, which can be a prerelease), a name in two dependency groups, and yarn's reading ofresolutionsin a migrated lockfile.Npm). The same merge can leave one. A fresh resolve links a range to a workspace only when the version fits, so the binding is stale, but re-resolving it sends the name to the registry, and a private workspace name fails there. That is a separate change with its own rule per resolution tag.locked_version_is_out_of_rangekeeps its prerelease exemption and its name-level rule exemption. The scan after the clean checks every row with the shared leaf, so a direct row bound to a prerelease outside a range that is not*is refused by the scan, with the scan's note. The resolver takeslatestonly for an empty or*range, or when the range accepts it, so such a binding is stale.redirect_moved_edgesis whatbun update <name>and a rule use: every row that shared the old package follows when its range accepts the new one. For a row that only its own range moved, that pulled the root's own row down (no-deps ^1.0.0locked at 1.1.0 followed a repairedone-fixed-dep/no-deps@1.0.0). The repair now passes only the rows a rule applies to.warn_orphaned_patchesran before the scan and reported the patch for the version that the repair brings back as orphaned.
