Problem

• A bare bun update exits 0 and removes a locked optional registry dependency from bun.lock when its manifest gets no answer (404, 503, --offline without a cached manifest). A later bun install --frozen-lockfile passes without it.
• Found by audit, no user report. Bun 1.4.3 does this too. Since 1.4.4 the package also leaves node_modules.
• Cause: an optional registry entry that bun update resolves again has no package until its manifest arrives (bind_row, src/install/PackageManager/PackageManagerEnqueue.rs:1959).

Fix

• refreshes_in_place gets a registry arm: the entry keeps its bun.lock package while its manifest is read again, like git, GitHub and tarball entries (Fix 7 regressions since 1.4.3 in bun install, bunx, bun patch, bun pm pack and bun: imports #46455). With no answer, bun update prints warn: name@version was not checked for updates.
• A manifest without a version in range still removes the package.
• Verified: test/cli/install/bun-install-retry.test.ts (67 new cases, 45 fail on main). Self-reviewed: 34 concerns raised, 34 addressed.

Background

• Scratch::refreshing has one bit per lockfile dependency: keep the package until the source answers.
• Earlier commits put the package back at each exit of bind_row, a second keep mechanism. This replaces them.

Downsides

• Exit codes: bun update --frozen-lockfile 1 to 0. An update that cannot download a required dependency of the kept package: 0 to 1, like bun install.
• Cost: .text +5,120 bytes, 3 instructions per resolved dependency in settle_without_manifest, about 1,100 per optional dependent in bun update <name>, 1 or 2 bitset allocations per update that has such an entry.
• Still removed: optional dependencies of a package that moves in the same update, catalog: entries, packages that an overrides rule names (list in Notes).

Notes

Why now, and who meets it

• Found by audit. No user has reported it. The bun.lock removal is in Bun 1.4.3 too. The removal from node_modules is new in 1.4.4 (1.4.3 leaves the installed package in place).
• The trigger is narrow: a registry entry in the project's own optionalDependencies, a bun update, and only that manifest without an answer. Example: an optional dependency on a scope registry, and a person or a job that runs bun update without the token of that registry (a 401, 403 or 404).
• The loss lasts until the next healthy bun update that selects the entry. No install of the unchanged project restores the package.
• A workaround exists on main: bun update '!old' leaves old alone and sends no request for it.
• The rule is already on main by two merges: install: pnpm parity — dedupe, prune, pm licenses, audit fix, add --filter/--catalog, nested overrides, transitive update, and workspace fixes #38333 keeps a transitive registry package with this warning, and Fix 7 regressions since 1.4.3 in bun install, bunx, bun patch, bun pm pack and bun: imports #46455 keeps an optional git, GitHub or tarball entry. Fix 7 regressions since 1.4.3 in bun install, bunx, bun patch, bun pm pack and bun: imports #46455 took fixes for regressions since 1.4.3 only. Its part for git, GitHub and tarball entries came from install: keep an optional git, GitHub or tarball dependency on its locked package while it is read again #46276, which lists registry ranges as still removed and names this PR for them.
• Open question for a maintainer, as in install: keep an optional git, GitHub or tarball dependency on its locked package while it is read again #46276: keep the package and exit 0, or fail the command. pnpm 12 and Yarn fail. This PR keeps, as main does for the other source kinds.

What each command prints and writes (root optionalDependencies: { "old": "^1.0.0" }, bun.lock has 1.1.0)

bun update, GET /old answers 404	exit 0, warn: GET <registry>/old - 404, old removed from bun.lock and node_modules	exit 0, warn: old@1.1.0 was not checked for updates: GET <registry>/old - 404, nothing written

later bun install --frozen-lockfile, healthy registry	exit 0, old is not installed	exit 0, old@1.1.0 installed

Exit codes that change

Command	main	this PR
bun update --frozen-lockfile, the optional manifest gets no answer, nothing else moves	1	0
bun update with an empty cache and no node_modules, the optional manifest gets no answer, and the tarball of a required dependency of that package cannot be downloaded	0 (the optional package is removed)	1, as bun install on the same tree
bun update --offline, a workspace has a peer dependency on the entry, manifest not cached	1 (--offline: no cached manifest)	0
bun update, a workspace has a peer dependency on the key of an npm: alias entry, the alias target answers 404	1 (the peer dependency asks the registry for the key)	0

Each row has a test. The last two are consequences of the design: the entry has its package while the peer dependencies are resolved.

Which entries keep their package

• An optional entry that asks for a range, *, an exact version, a dist-tag, or an npm: alias of one of these.
• Declared by the root, a workspace member, a file: folder, a registry package (for bun update <name>), or a git, GitHub or tarball package that is read again.
• The bun.lock package must have the name that the entry asks for. For a range it must also have a version that the range accepts. So an entry whose range was edited keeps its package if the new range still accepts the version. * and an alias without a range accept every version, also a prerelease that latest points to.
• Not only bun update: a tarball package whose bytes changed is read again by bun install --force and by bun add <the same tarball>. Its optional registry dependencies are kept there too. Main does the same for an optional GitHub dependency of such a package.

How it works

• Diff::keep_while_refreshing runs where bun update takes the package from entries: the root, a workspace member or file: folder that is read again, and a git, GitHub or tarball package that is read again. It gives an entry that refreshes_in_place its bun.lock package back and sets its bit. enqueue_named_updates does the same for bun update <name>. None of these four call sites changes.
• settle_without_manifest no longer treats an entry with a set bit as resolved, so the registry lane asks for its manifest as before. A manifest that arrives resolves the entry, and assign_resolution clears the bit.
• The exits of bind_row without a manifest (a failed request, a request that cannot be made, --offline) get no code. The entry still has its package and its bit.
• unbind_refreshing_without_version is the one exit with new code. A manifest that has no version for the entry removes the package, as on main. Under --offline that manifest is a cached copy that cannot be read again, so the package stays.
• At the end, warn_unchecked_sources prints one line per package that still has a set bit. warn_unchecked records what it printed, so a package that a plan also reports gets one line.
• refresh_children_of_named (bun update <name> --latest) skips a dependency that still has its bit. The planner (plan_edges) skips it too. Main does both for a dependency without a package.
• npm::accepts_locked is the * rule that rows_outside_overrides and is_as_yarn_resolves had inline. The arm uses it too.

Why package.json is not written for a kept entry

Without the kept list, bun update writes a new range for an entry that it did not check. Observed on a build without the skip: bun update old --offline changed "old": "^1.0.0" to "^1.1.0" in package.json and saved bun.lock, next to warn: old@1.1.0 was not checked for updates. Lockfile::entries_kept_without_refresh reads the set bits from the lockfile of before the clean, and edit_update_entries and edit skip those entries. The key is the workspace and the entry, so a workspace that has the same key for another package is still written. A peer range that another workspace has for the kept package is written as on a healthy run. Main does that too (bun update -r).

Choices for a maintainer

• Keep at exit 0, or fail (see above).
• A 404 keeps the package, like a tarball URL that answers 404 on main.
• A command that selects the entry fails only when a request fails: fail_update_requests on main, unchanged. Under --offline, and for a registry URL that bun cannot ask, no request is sent, so the package stays and the command exits 0 with the warning. Main does the same for a GitHub entry. An earlier version of this PR failed the command there (exit 1 with a new error text). The self-review asked to take that out, because it applied to registry entries only and no maintainer has answered keep or fail.
• A range entry keeps its package if the range accepts the locked version. The text of the range can differ from the text in bun.lock. The differ uses the same test on bun install.
• A registry package gets the one-line warning that a transitive package gets (name@version was not checked for updates: <failed request>). Git, GitHub and tarball packages keep their two lines.
• bun update <name> --latest no longer asks about the dependencies of a named package that got no answer. For a registry entry this keeps the one request that main sends. For a GitHub entry it removes the manifest requests that main sends for those dependencies before it exits 1 (measured: one request less in a fixture with one dependency).
• The entry of an overrides rule: the existing test of the predicate is kept (a rule that names the package, in any scope). The docs sentence now says "names" and not "sets". The self-review offered a narrower test for registry entries. It is not taken here.

Still removed, as on main

• The optional dependencies of a package that moves in the same update. They are new entries without a package of their own. Main prints was not checked for updates and leaves the dependency out. install: retry an optional dependency that an earlier install left unresolved #45942 asks again for such an entry on a later install.
• catalog: entries, and an entry whose package any overrides rule names.
• An entry that moved between dependency groups since the last install (for example from dependencies to optionalDependencies). The pairing is by group, also for git, GitHub and tarball entries.
• A workspace entry that follows an npm: alias that another package.json of the project has under the same key. The alias entry keeps the package, and the follower is saved as "unresolved".
• A request that rewrites the range to one that rejects the locked version: bun update old@^9.0.0 --offline writes ^9.0.0 and leaves old out at exit 0.
• A 200 answer that lists no version (for example {}). It counts as an answer.
• An optional file: folder or link: whose directory is gone. install: keep an optional git, GitHub or tarball dependency on its locked package while it is read again #46276 left these out on purpose: the linkers fail on a missing folder.
• Required dependencies. Only an optional dependency keeps its package.
• --offline with a cached manifest that is older than bun.lock and lists only a lower version in the range. bun takes it as an answer and moves the entry down.
• --prefer-offline with minimumReleaseAge, when the cached manifest does not list the version of bun.lock and the gate refuses every version that it lists. bun does not ask the registry again and leaves the entry out at exit 0. A required dependency fails with exit 1 in the same setup, so the cause is in the age gate and not in this change.
• With a bun.lock from Bun 1.4.3 or older, a tag entry that never resolved is bound to a package of its name. The arm keeps that package when no answer comes, as main does for a GitHub entry.
• Every one of these runs ends in (no changes) or Saved lockfile, and nothing names the removed package. That is a separate reporting change.

Related pull requests

In the update scenarios the range of one series is between 660,000 and 1,360,000 instructions. The bun update <name> difference also shows in the lowest run of each series (+56,992). bloaty, perf, valgrind and strace are not installed here.

The extra work in bun update <name> is refreshes_in_place plus the search for the package that declares the dependency, once per optional dependency on <name>. Main does the same for git, GitHub and tarball dependencies.

Checks

• 194 healthy fixtures: requests, output, bun.lock and package.json are identical to main in all 194. 50 have the entry in the root (a range, an alias, a dist-tag, an exact version, a range that an installed package shares) and run update, update --latest, update <name>, install --force and install. 144 have it in a workspace member, a file: folder or a GitHub package (four entry shapes) and run update, update --latest, update -r, update --filter, update <name> and install --force. Each runs with and without a newer version in the registry.
• 38 shapes in which the manifest gets no answer: main removes the package from a saved bun.lock at exit 0 in 34, this PR in 5. The 5 are a catalog: entry, an entry with an overrides rule, and three where the package that declares the entry moves in the same update. 18 control shapes (named requests, required entries, bun install, bun add, a registry that answers) are identical to main.
• The 102 cases of the earlier commits of this PR, run against this build: all 22 that pass on main pass. 42 more pass. 38 fail: they assert the earlier design (an entry that moves between groups or workspaces on bun install, catalog: and overrides entries, the dependencies of a package that moves, exit 1 for a selected entry under --offline).
• Each part of the diff was turned off in a local build, in two builds with several parts each. Every part fails at least one case: the exit with a manifest that has no version (three cases), the --offline exception of that exit, the pairing by range, the * rule (three cases), the skip in refresh_children_of_named, the skip in plan_edges, both write-back skips, the choice of the reason, the order of the lines, and the one-line record.

Tests

• test/cli/install/bun-install-retry.test.ts: the suite a locked optional dependency whose source cannot be read again gets a registry kind, so its existing it.each cases run for a registry entry declared by the root, a workspace member, a GitHub package and a registry package. 67 new cases, 275 in the file. With the src/ of main 45 of the new cases fail. The other 22 pin what must not change (a healthy update moves the entry and rewrites its range, a required entry fails, overrides and catalog entries, a manifest without a version in range or with only versions that are too new, named requests after a failed request).
• Also run with the debug build, 0 failures: bun-update-transitive (326), bun-update (175), bun-update-lockfile-sync (172), bun-lock (317), bun-audit (260), bun-install-offline (12), bun-install-offline-misses (35), catalogs (155), minimum-release-age (244). Of these only bun-update-lockfile-sync runs the new arm.

Self-review

34 concerns. Changes made for them: the end-of-resolve check that failed a selected entry under --offline is removed. && !failed became a skip of the dependency that got no answer. The exit with a manifest that has no version tests --offline and no longer the origin of the manifest. * and an alias without a range keep a prerelease. One record in warn_unchecked replaces the list that only one planner filled, which fixes a double line under bun update <name> --latest. The docs sentence is narrower. 26 cases were added for the parts that had none (peer dependencies, a registry package and a tarball package as declarer, tags, the age gate, the order and the reason of the lines). Not taken: a narrower overrides test for registry entries, a keep for the entry that follows an alias, and pairing across dependency groups. Each is listed under "Still removed".

Walkthrough

Optional dependency updates can retain eligible locked packages when a source cannot be reached or resolved. The update flow preserves matching package.json entries and reports warnings. CLI tests and update guidance cover fallback conditions and cases that remain errors.

Changes

Optional Dependency Fallback

Layer / File(s)	Summary
Resolve failures and retain eligible packages src/install/PackageManager/PackageManagerEnqueue.rs, src/install/lockfile.rs, src/install/npm.rs, src/install/lockfile/Package.rs, src/install/PackageManager/install_with_manager.rs	Optional npm and dist-tag dependencies can refresh in place. Eligible resolution errors unbind refreshing rows outside offline mode. Lockfile tracking and locked-version checks support this path.
Carry retained entries through update processing src/install/lockfile.rs, src/install/PackageManager/install_with_manager.rs, src/install/PackageManager/PackageJSONEditor.rs, src/install/PackageManager/package_json_write_back.rs, src/install/PackageManager/add_catalog.rs, src/install/PackageManager/add_remove_with_filter.rs	The update flow passes entries kept without refresh through package.json editing. Matching dependency entries are skipped rather than rewritten.
Report unchecked packages consistently src/install/PackageManager.rs, src/install/update_transitive.rs	Warning reporting tracks previously reported package-version pairs and matches registry manifest failures to fetch warnings. Update planning skips dependencies refreshing in place.
CLI regression coverage test/cli/install/bun-install-retry.test.ts, docs/pm/cli/update.mdx	Tests cover retry handling and optional registry dependency updates across aliases, workspaces, offline operation, selection, lockfile retention, and warnings. The update guide states fallback conditions and selected-dependency errors.

Status

• Reproduction: a loopback registry serves one optional dependency (old, locked on 1.1.0) and answers 404 or 503 for its manifest during a bare bun update. On main (5c6d4e2) the command exits 0 and removes old from bun.lock and node_modules. A later bun install --frozen-lockfile on a healthy registry exits 0 without it. With this branch the command keeps old@1.1.0, prints warn: old@1.1.0 was not checked for updates: GET <registry>/old - 404, and writes nothing.
• The branch now builds on the mechanism that Fix 7 regressions since 1.4.3 in bun install, bunx, bun patch, bun pm pack and bun: imports #46455 merged for git, GitHub and tarball dependencies. It replaces the earlier commits of this pull request. The branch no longer conflicts with main.
• Tests: bun bd test test/cli/install/bun-install-retry.test.ts. All 275 cases of the file pass with this branch at 3137926. With the src/ of main, 45 of the 67 new cases fail.
• Pull request: install: keep an optional registry dependency on its locked version while its manifest is read again #45966

[claude]

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.

Beyond the inline findings, I also checked two things in keep_locked and ruled them out: assert_kept_locked_in_range only runs under Environment::CI_ASSERT (install_with_manager.rs:688), so it is not a release-build panic on user input; and with two in-range versions of a package in bun.lock, DirectDependencies::package_of matches the row's prior package by name hash and behavior and had.filter(accepts) takes it first, so a failed request does not move the entry.

Extended reasoning...

The change restructures bind_row in src/install/PackageManager/PackageManagerEnqueue.rs so manifest failures, --offline misses, and cached NoMatchingVersion fall through to a new keep_locked tail that rebinds an optional row to an in-range bun.lock package, adds kept_locked/warned_unchecked/direct_before state on PackageManager, and wires a per-package warning plus package.json write-back skip through update_transitive.rs and PackageJSONEditor.rs. It touches no auth, crypto, or path-handling surface, but it changes exit codes and lockfile contents for plain bun install on flaky registries, which is a behavior decision the inline findings flag for a maintainer.

first clean_lockfile call in install_with_manager by assigning
DirectDependencies::default() to manager.direct_before. This prevents
keep_locked and later bind_row processing from comparing post-clean package IDs
against pre-clean data while preserving earlier direct_before consumers.

#46276 fixes the same loss for optional git, GitHub and tarball dependencies, which this PR lists under "Not covered, as on main".

It uses another mechanism: the dependency keeps its bun.lock package while it is resolved again, and a per-dependency bit (Scratch::refreshing) tells the resolver that it still has to resolve it. No failure arm binds the dependency again.

If a maintainer accepts that state, this PR can rebase on #46276:

• A registry range that is declared as in bun.lock can stay bound in the same way. Then keep_locked is only needed for a dependency that starts without a package.
• Both PRs then print one line for a kept package: warn: <name>@<version> was not checked for updates.
• The docs bullets of the two PRs in docs/pm/cli/update.mdx can then state one rule.

Both PRs need the same decision: keep and warn at exit 0, or fail the command.

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.

Commit 87b3ca3 addresses the earlier bun update <name> --offline concern: lacks_version_in_cache now fails a request only when the row is the package.json entry the request names (is_entry_of_update_request), so a transitive optional row of the same name no longer fails the command. Beyond the inline note, I also checked whether the was not checked for updates line loses the registry's reason when a cached manifest lacks the range and the online refetch then fails — the failed task's log is still attached, so the reason is printed.

Extended reasoning...

The change rewires bind_row's no-answer exits in PackageManagerEnqueue.rs into a keep_locked tail, moves the DirectDependencies snapshot onto the manager, and re-plumbs the transitive update planner, with ~1,280 lines of new tests; it touches no auth, crypto or injection surface but does change what bun.lock records after a failed manifest request. The latest push resolves the one high-severity finding from the previous run, leaving a single nit about alias write-back under --offline. The size and the resolution-semantics changes to plain bun install still warrant a maintainer's judgment.

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.

Beyond the inline finding, I also checked two spots in the reworked design: mark_refreshing now sizing the bitset by dependencies.capacity() — every id it sets is below len(), so set stays in bounds and entries_kept_without_refresh only visits set bits; and the kept-entries snapshot being read from lockfile_before_clean — clean_lockfile swaps the old lockfile out via mem::replace, so its Scratch::refreshing state is intact when edit_after_resolve consults it.

Extended reasoning...

The branch was squashed into a single new commit that replaces the earlier keep_locked design with an extension of the existing refresh-in-place path to Npm/DistTag rows, plus a kept-entries skip in the package.json editors; the two checks above were the newly introduced mechanics most likely to misbehave and neither does.
