Beyond the inline findings, I also checked the pending-task accounting in on_optional_download_fail (Installer.rs:473): it stores Step::Done before resuming waiters and decrements exactly once per waiting entry, mirroring on_task_fail, so the install loop cannot hang on pendingTaskCount() == 0. The hoisted no-callback fallback in run_tasks emits the same single warning/error as before (the warning moved above the callback dispatch without duplicating), and the extract/integrity failure arm intentionally still passes is_required = true, matching the hoisted linker's error treatment.
Extended reasoning...
Four verified findings are posted inline (shared optional+required download edge, bun add --optional/bun update exit-code regression via the continue before fail_update_requests, dangling node_modules symlink after an optional download failure, and missing isolated coverage for the --offline arms), so this note only records what else was examined. I traced on_optional_download_fail against on_task_fail and on_task_complete in /home/claude/bun/src/install/isolated_install/Installer.rs: both callers (on_package_download_error and on_download_not_queued) store Step::Done before calling it, and it performs one decrement_pending_tasks plus resume_unblocked_tasks, so the pending-task slot is released exactly once and dependents are resumed. In /home/claude/bun/src/install/PackageManager/runTasks.rs the !is_required warning now fires before the callback branch and the old else warning was removed, so the hoisted (no-callback) path prints the same single diagnostic as the base; the extract-error, manifest, git, and github callback sites pass true, keeping those as hard errors consistent with hoisted. AsyncModule.rs ignores the new flag, which preserves its prior behavior apart from an extra manager-log warning for optional deps.
2 verified lower-impact observations (convention, logging or cleanup points) were not posted.
Findings marked 🟡 are optional suggestions and need no follow-up push.

On the extract and git failure sites in run_tasks: they pass is_required = true on purpose. The hoisted linker reports an extract failure (an integrity mismatch, a bad archive) and a git clone or checkout failure as an error for every dependency, optional or not. The isolated linker does the same with this PR. The download sites, where the hoisted linker warns for an optional dependency, pass the recorded flag. |

I re-reviewed the latest push (6ceed9b, d05e470) and found no new bugs; since this reshapes the isolated linker's failure handling across the main thread and worker tasks, a human look is still worthwhile before merging.
What was reviewed:
unlink_links_tonow walks every entry's dependency list (so a public-hoist root link is covered) and only touches Root/Workspace/Folder parents; global-store parents keep their links by design.on_optional_download_failordering:missingis set and links removed before theReleasestore ofStep::Donethatis_task_blockedacquires; the trailingunlink_missing_dependenciescovers a parent that relinked concurrently.run_tasksreordering: the non-callback (hoisted) path still emits the same warning/error andfail_update_requestsas before; the callback path now gets both plusis_required.--offlineoptional miss with a later required edge onto the same entry still ends inFailed to installwithout a named error — that is pre-existing on the base, not introduced here.
Extended reasoning...
Overview
The PR touches src/install/PackageManager/runTasks.rs (threads is_required through the download-error callbacks and moves the optional-dependency warning and fail_update_requests ahead of the callback dispatch), src/install/isolated_install.rs (new missing/required_entries fields, four not-queued arms routed through on_download_not_queued, a final unlink_missing_dependencies pass), src/install/isolated_install/Installer.rs (new on_download_not_queued, on_optional_download_fail, lazily built entry_is_required bitset, links_each_install, unlink_links_to, shared append_dependency_link_name), src/install/isolated_install/Symlinker.rs (extracts remove_link), a one-line signature update in src/jsc/AsyncModule.rs, and two new tests in test/cli/install/bun-install-retry.test.ts. Net ~430 lines across the package manager's link phase.
Security risks
None specific to this change. The only filesystem mutation added is remove_link on paths the installer itself computed from lockfile package names via the same append_dependency_link_name logic that creates the links, so no new user-controlled path is introduced. Errors from unlink/rmdir are ignored, which matches the pre-existing behavior in Symlinker.
Level of scrutiny
High. The installer coordinates main-thread bookkeeping with worker tasks via atomic step states; the new on_optional_download_fail releases a pending-task slot and resumes waiters on a path that previously counted as a hard failure, and symlink_dependencies now reads a new AtomicBool from worker threads. I traced the Release/Acquire pairing against is_task_blocked, confirmed the not-queued arms previously only bumped summary.fail (so the required branch of on_download_not_queued is behavior-preserving), and checked that unlink_links_to computes the same link name as symlink_dependencies. The bug-hunting run exited on a dry streak with no findings, and the prior inline findings from earlier pushes correspond to code that now exists (dependency-list walk instead of parents, optional-peer exclusion in entry_is_required, fail_update_requests before the callback, the Root/Workspace/Folder restriction). Still, concurrency plus exit-code semantics for bun install is a place where a maintainer familiar with the isolated linker should confirm the design choices (global-store parents intentionally keep dangling links; --offline optional misses are now silent for the isolated linker).
Other factors
The new tests exercise both linkers from a lockfile, assert the exact warning line, the absence of a node_modules/BaR entry via lstat, exit 1 for bun add --optional, and no changes on a repeat install, which covers the behaviors the PR claims. The PR description reports the change was checked against Windows via cargo check, which matters because remove_link has a #[cfg(windows)] arm that Linux builds do not type-check. Changed paths are not covered by CODEOWNERS. No third-party CHANGES_REQUESTED reviews are outstanding; coderabbit threads were resolved by a non-author.

🔴 Maintainers get a timing-dependent test: in the order where the required dependent's manifest resolves BaR first, the fresh install never writes bun.lock and line 663 rejects. The resolve phase enqueues BaR's tarball with the first resolving edge's behavior (PackageManagerEnqueue.rs:2483); when that edge is aneeds/zneeds's required one, the 404 is logged as an error and install_with_manager.rs:923 calls Global::crash() before save_lockfile at :958. Fix: make the first install deterministic for both orders, e.g. make BaR a root dependency so root's edge is always first in the manifest callback list, or write bun.lock yourself (or --lockfile-only) before the from-lockfile install, so each it.each case covers both the fresh and the lockfile path it claims.
Why this was flagged
Trigger: the it.each(["aneeds", "zneeds"]) case at test/cli/install/bun-install-retry.test.ts:657-665 where pkg (optionalDependencies BaR) and the required dependent are both root deps and only their manifests reach BaR. get_or_put_resolved_package enqueues the tarball on first resolution with behavior.is_required() of that edge (PackageManagerEnqueue.rs:2479-2484); the second dependent finds the existing package at :2360-2377 and enqueues nothing. When the required edge is first, the 404 reaches runTasks.rs:937-946 with is_required == true and no callback, so error: GET …/BaR-0.0.2.tgz - 404 is added to the manager log. install_with_manager.rs:658 captures had_errors_before_cleaning_lockfile; after the link phase :922-923 calls Global::crash() before save_lockfile at :958, the only save site. So bun.lock is never written and await access(join(package_dir, "bun.lock")) at line 663 rejects, failing the test; which of the two orders hits this depends on manifest response timing, so the case is flaky rather than covering 'both orders'.
Verification: The tarball's dedupe entry gets is_required from the FIRST edge that resolves BaR (src/install/PackageManager/PackageManagerEnqueue.rs:2483). install_with_manager.rs:922-923 calls Global::crash() before save_lockfile at :958. Therefore in the required-first order the fresh install exits 1 without writing bun.lock, and test/cli/install/bun-install-retry.test.ts:663 rejects.

🟣 pre-existing, not blocking: pre-existing: isolated-linker users running bun install --production (or --omit=dev, or --filter without the root) still get exit 1 when a tarball only optional edges reach in that install fails, while the hoisted linker warns and exits 0. entry_is_required at Installer.rs:497-505 reads every lockfile edge of each stored package, but the store build drops edges that fail is_placed(dep_features) or install_root_dependencies (Tree.rs:599-608), so a root devDependency edge marks the package required even though nothing in this install links it as required. Fix: apply the same placement filters the store build uses (is_filtered_dependency_or_workspace, or at least is_placed with the parent's features) when building required_packages, so only edges that are actually installed count.
A small fix can ride a push you are already making; otherwise a short reply is enough.
Why this was flagged
Trigger: linker = "isolated", root package.json has devDependencies { X } and dependencies { P } where P has optionalDependencies { X }; the user runs bun install --production and X's tarball 404s or is absent under --offline. The store build skips the root dev edge because !dep.behavior.is_placed(dep_features) (src/install/lockfile/Tree.rs:599-601), so X is only reached through P's optional edge. On failure run_tasks calls Installer::on_package_download_error with is_required = false (Installer.rs:281), or the AlreadyFailed arm calls on_download_not_queued (Installer.rs:459). Both call entry_is_required, which loops every stored package's lockfile dependency list and only excludes is_optional() and is_optional_peer() edges (Installer.rs:501-502); the root's DEV edge passes, required.set(res) marks X, and the entry takes the on_task_fail path: summary.fail += 1, exit 1. The hoisted linker in the same install only sees the enqueued optional edge and prints the warning with exit 0. The base branch also exited 1 here, so this is a gap the PR's fix leaves open rather than a regression.
Verification: pre-existing (base fails the same way by the same route; the PR's fix does not reach this variant, so it is a gap in the stated purpose, not a regression). src/install/lockfile/Tree.rs:599-608 filters the unplaced root edge from the store, but entry_is_required (Installer.rs:499-505) reads the full lockfile edge list and marks X required, so the entry takes on_task_fail and exit 1.

### What does this PR do?
It consolidates 597 open package manager pull requests into one reviewed
change for Bun 1.5. Each was ported, taken in part, or left out with a
reason. This is the complete change log: `X -> Y` = symptom on main ->
behaviour now; a line without `->` names a symptom that is gone; dep =
dependency.
| absorbed | in part | not taken | obsolete | total | issues closed |

699 files, +150,684 / -85,553 (src 221 files +41,383 / -46,459, net
-5,076).
#### Behaviour changes someone will notice
1. Unknown long flags are errors in every package manager command and
bunx (main: `bun install --network-timeout 100000` adds the package
`100000`). Drop the flag; bunx: tool flags go after the tool's name. In
`BUN_OPTIONS` they are skipped.
2. `bun ci`/`--frozen-lockfile` fail (`note: dependencies in
package.json changed since bun.lock was saved`) when a dep of the root
or a workspace was added, removed, re-grouped or re-ranged. Equivalent
spellings, `file:` directory rows (warning),
`trustedDependencies`/`patchedDependencies` edits pass. Run `bun
install`, commit (#41931; refs #22689).
3. `file:` folders are hard-linked real files (hoisted: was a symlink
per file, their deps did not resolve). The folder's own `node_modules`
is not taken, except `bundleDependencies`. Linked, and trusted scripts
run, once, not on every install. Declare or bundle what the folder
needs; `link:` / a workspace for a live link; `--force` reruns scripts
(#40628, #37127; fixes #13379).
4. Hoisted: what the previous `bun.lock` placed and the new one does not
leaves `node_modules`, with what only it needed and its bins; not under
`--filter`, not what no lockfile placed (`bun prune`) (#29794, #44406).
5. One-time re-downloads: registry metadata (cache format bump), `file:`
/ URL tarballs, packages of registries on a port, path or http; `bunx`
starts a new cache.
6. Retries wait: a registry that refuses connections costs about 9 s
before the install fails (main: at once).
`BUN_CONFIG_HTTP_RETRY_BACKOFF=<ms>` sets the first wait.
7. Dep names over 255 bytes per component are refused (main: a
4,100-byte name in a manifest aborts), as are the names under Security.
8. Workspace's symlinked `node_modules` is replaced by a real directory,
like links at `@scope`, `.bin`, `.bun/**` (main wrote and deleted
through them). Only the root `node_modules` link is followed: link the
root, not members (#42039).
9. `"trustedDependencies": []` kept the default trusted list off only on
the install that created `bun.lock` -> always, also in a checkout
without the workspace that declares it; written to `bun.lock` (one line;
Bun 1.4 honours it, drops it at its next save) (#44765).
10. `!dir/**` in `workspaces` also removes `dir`, as npm; negated
entries work in every spelling (`!./pkg`, `!pkg/`) and position, add no
members; `bun run --filter`/`--workspaces` follow them (#43401, #43400;
fixes #43399).
11. `bun pm ls` lists what is on disk, exits 1 without `node_modules`;
isolated: a dep of the root only if its link exists (#38923; fixes
#38909).
12. Linker sticks: while `node_modules/.bun` exists, a command that
names no linker keeps the isolated layout (main: lays hoisted over it).
Back: `--linker=hoisted` or delete `node_modules`.
13. `NODE_ENV=development`/`test`: `bun install` reads the `.env` files
`bun run` reads, not the production ones.
14. `--provenance`, `--provenance-file`, `publishConfig.provenance`,
`NPM_CONFIG_PROVENANCE`, `provenance=true` in `.npmrc` are errors (main:
published without it). Unset them or publish with npm (#30522; refs
#18611).
15. `packageExtensions` adds a key to `bun.lock`, a trailing section to
`bun.lockb`, only when an extension added something; older versions load
both.
16. Fresh resolves pick differently (locked versions stay): see
Resolver; Overrides. glibc hosts stop installing `-musl` variants
(`--libc='*'` for both).
17. New `warn:` lines: incorrect peers, deprecated versions, skipped
required deps, stale / misplaced `patchedDependencies`, unreadable
config files, retries, unusable hashes.
18. Dep's script finds its own `.bin`, then the inherited `PATH`, then
shared `.bin`s, so an untrusted package's `node` bin cannot run inside a
trusted script. Cost: a global `node-gyp` wins over the project's, for
dep scripts only (#44488).
19. If `bun install` itself is killed while a trusted dep's script runs,
the next install calls the package installed (registry packages: as
main; `file:` folders, local tarballs: the rerun on every install hid
it). `bun install --force` (#42001).
#### Decisions that need the maintainer's confirmation
- Frozen installs start failing (2). Of 241 `bun.lockb` files from this
repo's release tags, 6 that pass on main fail here (4 real drift).
- A frozen install with only a foreign lockfile writes nothing: no
`bun.lock`, no package.json edit, one note (#38804). Reverses #38333.
- Changes 1, 9 (teams on 1.4 and 1.5 see the `[]` line come and go), 10,
11, 12 (removing `linker = "isolated"` no longer switches a tree), 14,
18.
- The `packageExtensions` lockfile key (15): without it an edited or
removed extension cannot be told from the package's own deps. #43104 /
#43209 are out for needing a key.
- Scripts that run now and did not: #41803 (its opposite #41866 is out),
#41845, #39443, #43913, #42001, #38780, `bunx --trust`. No longer: root
scripts under `--dry-run`; under frozen, scripts of an installed package
trusted after the lockfile was saved (main: every frozen install; now a
plain install once, frozen never, silently).
- No state file, so a killed install goes unnoticed (19). The complete
fix is one bit or list per project, read once per install.
- Tarball cache entries named by integrity; full manifests by package
name for `libc`; #38813; +1 `renameat` per linked package (#38783); a
token survives only an http -> https redirect on one hostname (#38001);
#39603 flips a row of #38867.
- Hoisted thread pool on macOS: on; CI only, no stress run.
- Open: mask URLs in source excerpts under a diagnostic (not done);
should `bun pm pack` follow a symlinked `node_modules` (it does,
#41925).
#### New features and flags
- Yarn Berry migration (on main since): here package.json is written
just before `bun.lock` and only if that is saved; `link:` stays `link:`;
`libc` is honoured (#40057)
- `link:./dir`, `link:../x`, absolute paths: symlink to that directory,
relative to the declaring package.json, as Yarn / pnpm; `link:foo` stays
a `bun link` name (#40025; fixes #4719, #5045)
- `packageExtensions` in the root package.json adds missing deps / peers
to registry packages, can mark a peer optional (#40053)
- `bun pm cache pack <file>`/`unpack <file>`: the cache entries a
lockfile needs as one file (CI); unpack adds what is missing, refuses a
damaged pack whole (#40012)
- `bun pm cache prune [--max-age <days>] [--dry-run]`: drops cache
entries older than 30 days, not the global store (#42592)
- `bun pm fetch`: downloads all deps (pinned git too) into the cache; no
`node_modules`, scripts or lockfile write (#29509)
- `bun publish --recursive`/`--filter <pattern>`: packs the selected
workspaces, publishes deps first, skips private and already published
ones; the first failure ends the run (#41292)
- `bun update --depth 0`: direct deps only, transitive ones stay locked
(#41720; fixes #41625)
- `bun prune --check`: exit 1 when anything would be removed (#39216)
- `minimumReleaseAgeExcludes` takes `name@version`; new
`--minimum-release-age-excludes a,b@1.2.3`; `bun audit fix` honours the
list (#37909, #42803; fixes #28967, #42799)
- `minimumReleaseAge` accepts `90m`, `12 hours`, `3d`, `2 weeks`;
`nan`/`inf` are config errors; `0` no longer fetches full manifests
(#30529)
- `libc`: on Linux only the glibc or musl variant of an optional native
package is installed; recorded in `bun.lock`; `--libc` overrides
(#38797; fixes #16282)
- `bunx --cwd <dir>` (#28669; fixes #28668)
- `bunx --env-file <file>` (main: `unrecognised dependency format:
@.env`); not `bun --env-file F x pkg` (#35599; fixes #12430, #17759)
- `bunx --minimum-release-age`, part of its cache key (#30751; fixes
#30748)
- `--env-file`, `--no-env-file`, bunfig `env = false` for all package
manager commands (main: `--env-file ci.env` added the package `ci.env`)
(#36672; fixes #12011, #31450)
- `npm-shrinkwrap.json` is migrated like package-lock.json (#38861)
- Deprecated versions are reported: one line per direct dep, one for the
rest, all with `--verbose` (#35457; fixes #6883)
- `bun add -d | --optional | --peer <pkg>` moves a package another group
lists; `--save-prod` moves it back (#36284; fixes #4852, #5714)
- `bun audit fix` reports and rewrites the `overrides` rule that holds a
vulnerable version (#38785)
- `bun pm pkg set`/`delete`: arrays (append, index), bracketed names
(`exports[./package.json]`) (#38025; fixes #22035)
- `--dry-run` for `bun link`, `unlink`, `pm version`, `pm cache rm`, `pm
trust`, `pm pkg`, `pm migrate` (main: they wrote) (#41690)
- `bun publish` honours `publishConfig.registry` and
`publishConfig["@scope:registry"]` (#38322; fixes #18670)
- Auto-install reads registries and credentials from `.npmrc` (main:
`@corp/x` came from the default registry) (#44754)
- `NPM_CONFIG_USERCONFIG` names the user `.npmrc`, as
`actions/setup-node` sets it (#38047)
- `Cache-Control: no-cache`, `no-store`, `max-age` under 300 s on
registry metadata (#41644)
- Workspace can depend on the root package with `workspace:*`, also for
pack / publish (#36594; fixes #2773, #5176)
- `"gypfile": false` turns off the implicit `node-gyp rebuild`; a
trusted tarball, git, `file:` package with `binding.gyp` and no scripts
is built like a registry one (#43913; fixes #43903)
- Scripts get `npm_package_name`/`version`/`json` of their own package,
`npm_config_local_prefix`, `npm_package_config_*`,
`npm_lifecycle_event`, `npm_lifecycle_script`; inherited `npm_package_*`
are dropped (#36690, #38110; fixes #12752)
- Hoisted linker links packages on up to 8 threads, whatever
`node_modules` holds (nothing, a part, other versions, `--force`) and
after a download; not on Windows; `file:`/`link:` / workspace / trusted
deps, bins and scripts stay on the main thread; everything in today's
order, scripts too; a cold install is no faster (#29496)
#### Security
- Registry URL that is not http(s) (`htps://`, no scheme): `pm view`,
`whoami`, `publish`, `audit`, `pm diff` sent the token there over plain
TCP; a bad `BUN_CONFIG_REGISTRY` fell back to another registry with the
token -> error, no request, on every route (#41662, #41773)
- Token, `_auth`, user or password with CR, LF, NUL could inject
headers, as could `--otp`, `--user-agent` -> refused (#37458, #41661)
- `token = "$NPM_TOKEN"` with the variable unset sent the literal text
-> warning, nothing sent (#41049)
- Passwords and tokens in registry, tarball, git URLs were printed in
errors, warnings, summaries, `--verbose`, `pm ls`/`why`/`view`/`diff`,
`audit`, migrations -> masked (#38977, #38997, #38817)
- Control characters from manifests, lockfiles, registry answers reached
the terminal (`pm view`, `licenses`, `untrusted`, `audit`, resolutions,
bin names, errors) -> escaped (#38536, #38631, #39358, #38525)
- Dep names `.bin`, `node_modules`, a bare `@scope`, with control
characters, empty or scope-only were installed or requested -> refused;
skipped with a warning in a third party's manifest (#44439, #38615,
#43331, #41735)
- Registry, git or tarball package could `link:` a directory, use a
local `.tgz` of the project or a `file:` path that leaves it -> refused
at resolve and install time (#39023, #38986, #43101)
- Dep's own `npm:` alias could replace a same-named direct dep of the
root; an alias in a refused or stale lockfile kept redirecting -> the
root's dep wins; loaders register no aliases (#44412, #44294)
- Frozen install asked the registry for a range that `bun.lock` links to
a workspace missing on disk (dependency confusion) -> fails without a
request (#43471)
- Global store: a trusted package's script could modify shared deps; `pm
trust` ran scripts in the store, saw nothing under isolated -> its
closure is project-local (#40239, #35106)
- Failing script of an optional workspace / `link:` dep deleted that
folder -> only what the linker placed goes (#43226)
- `bun prune`, `update`, `dedupe` removed packages behind a symlinked
workspace `node_modules` -> prune refuses (exit 1), the others skip it
(#44484; fixes #44669)
- `bun add -g`, `link`, `unlink` replaced or deleted foreign files in
the global bin directory -> only what Bun made (#39745)
- `bun pm cache rm` could delete the project, home or Bun's directory
(an empty `BUN_INSTALL_CACHE_DIR` meant the project) -> refused (#39750)
- Project's bunfig.toml could point `globalDir`/`globalBinDir` anywhere
-> ignored with a warning (#41775)
- `bunx` installed into the shared temp directory, where another user's
`node_modules` / package.json was loaded -> `<cache>/.bunx-<uid>`, 0700
(#44393, #31447)
- Applying a patch followed symlinks and wrote through hard links ->
refused (#32677)
- Tarball could make Bun allocate the disk or memory its headers claim;
sparse members keep their holes (#36542)
- `minimumReleaseAge`: an exact version passed when only the abbreviated
manifest was cached; so did a publish time that is not a date (#38659,
#43307)
- `BUN_CONFIG_NO_VERIFY=0` turned verification off, `=1` did not -> off
only for `1` or `true` (#38310)
- Manifest hash Bun cannot use skipped verification silently -> warning
(#38484)
- `bun audit` took a malformed registry answer for a clean audit ->
failed audit; a scoped registry is named and skipped (#38557)
- Pack: keys of a bundled dep that are not package names pulled in
outside files; `**/a/b` patterns, a BOM, trailing spaces disabled ignore
rules; a symlinked README was sent (#44902, #41531, #41871)
- `bun publish` published with `"private": "true"` or `1` -> any truthy
value is private (#41664)
- Auto-install read a package.json version from the wrong buffer, an
alias could redirect other packages (#42839)
#### Install core
- Killed or failed install left a half-linked package that later
installs accepted -> linked in a staging directory, renamed into place
(#38783; fixes #43256)
- Switching hoisted <-> isolated left a mixed tree -> whole tree
replaced, workspaces' `node_modules` too (#38779)
- Each linker switch kept a copy of the old tree in
`node_modules/.old_modules-<hex>` -> deleted after the install; `bun
prune` collects old ones
- `--dry-run` ran root lifecycle scripts and wrote `yarn.lock` (#38830)
- bunfig `[install] dryRun = true` was ignored -> honoured, also by
publish, `pm pack`, prune, dedupe, `audit fix` (#34979)
- Empty package.json (root or member) deleted the lockfile, exit 0 ->
error, lockfile kept (#39666)
- Download that failed for an optional dep was skipped (exit 0) although
another dep or a non-optional peer needs it -> `error: failed to
download <name>@<version>`, exit 1 (#43197, #43219; fixes #43214)
- `--offline` failed on what is below an optional dep it had skipped ->
only misses still reachable are errors (#43185)
- `--offline` exited 0 without a required dep of an optional package
installed in one place, missing in another
- Required direct dep left out for `os`/`cpu` was silent -> warning;
`bun add` reports it as skipped (#41956)
- `--production`/`--omit=dev` failed on a `workspace:`, `link:`, `file:`
devDependency whose target is missing -> left out (#36704; fixes #14134,
#15102)
- `--production` installed, and ran scripts of, a devDependency that is
also an optional peer; `bun prune --production` removes it (#42040)
- Commands that only read package.json opened it for writing -> work on
a read-only file (#38745)
- `$TMPDIR` on another file system than the cache kept a probe file per
install (#38859)
- `bun add`, `remove`, `update`, `patch` rewrote a package.json in which
nothing changed
- `Infinity`/`NaN` were written into package.json -> `null` (#41743)
- Relative `--cwd` was applied twice by `bun update`, `link`, `unlink`,
`why` (#31154; fixes #31152)
- Warnings from native code appeared at exit -> flushed when printed,
also from Workers (#43004; fixes #42989)
- `bun --bun run` worked only for the first user of a shared machine ->
`node` shim directory per user (#35565; fixes #7504)
#### Resolver and version picking
- Range picked a deprecated version (`@types/*` stubs under `*`) ->
prefers one that is not, like npm; a locked version stays until `bun
update` (#36630; fixes #7571, #25314)
- `bun add pkg` installed a deprecated `latest` -> highest release that
is not deprecated; `pkg@latest` still follows the tag (#40317; fixes
#40310)
- Missing or dangling `dist-tags.latest` failed add, install, `update
--latest`, hid the package from `outdated`/`update -i` -> highest
release, with a warning (#36671; fixes #12041)
- `*`, `npm:pkg`, `npm:pkg@*` skipped a prerelease `latest` -> follow
the tag, like npm (#39774)
- Wide range (`*`, `>=1`) nested the newest version -> shares a resolved
version that satisfies it; `bun update` no longer re-adds what `bun
dedupe` removed (#38770)
- `1.0.0 || ^2.0.0`, `=2.5.0 <2` resolved as their first exact version
(#30076)
- `>=0.5 0` was read as alternatives -> intersection, like npm (#32993)
- `^`, `~`, x-ranges admitted prereleases of their upper bound
(`pkg@>=5.0.0-alpha.0 <8` overrode `^4`) -> end at `<X.Y.Z-0` (#43102;
fixes #41371)
- Exact prerelease met a range that does not admit it (`overrides` keys)
(#43150; fixes #43138)
- `>1` meant `>1.0.0` -> `>=2.0.0`; `>1.2` -> `>=1.3.0`, like
node-semver (#43253)
- `<x`, `<*`, `>x`, `>*` matched everything -> nothing; `^x`, `~x` match
any version (#43258)
- Version number above 2^64-1 was read as 0 -> invalid (#42458)
- `Bun.semver.satisfies()` was true for `""`, `1.2.3.4`, `1.2.3 junk`
(#32998)
- `satisfies("1.0.0+build-1", "^1.0.0")` was false; `< =1` was misread
- `pkg@2x`, `1beta`, `1.2x` were read as ranges -> dist-tags (#35259;
fixes #19065)
- Words starting with `ssh`/`http` were read as URLs -> dist-tags
(#37133)
- Leading whitespace in a version literal (tag, folder, tarball, `npm:`,
`catalog:`) broke the install, lost a pin in `bun add --catalog`, or
panicked (#38331, #38309)
- Version published after the manifest was cached failed for up to 5
minutes -> manifest fetched again once (#39790)
- Root dep edited to another package (`npm:` alias) under a range the
old version fits kept the old package (#41774)
- Plain dep got a same-named `npm:` alias's package outside its range
(#43267)
- New dep that follows an `npm:` alias asked for a garbled name (`GET
/1.0.0no-deps - 404`) (#43515; fixes #23264)
- `file:` and `link:` on one directory became one package (#38114)
- `file:` folder in both `dependencies` and `devDependencies` was
duplicated (#41833)
- Editing package.json re-downloaded GitHub / tarball deps, re-fetched
git ones that `bun.lock` resolves (#37142)
- Registry package that bundles a `file:../x` dep failed to install
(#43125)
- Bundled dep's dep took a slot the bundling package resolves through
(#38848; fixes #29263)
- `bundleDependencies` were kept from one dependency group of a manifest
only (#38857)
- Tarball, folder or git package whose own `name` is invalid was
installed under it -> refused (#38633)
- Folder, tarball, git packages without a `name` got broken lockfile
rows -> named after their source (#38681; fixes #17060)
- Dangling `node_modules` symlink was a resolver error -> missing
module; isolated: a failed optional dep goes with the links to it
(#38756)
#### Hoisted linker
- overlayfs: a replaced package of a lower layer kept its old files
beside the new ones, exit 0
- Install over an existing `node_modules` hung when the OS refused the
pool's first thread
- `bun prune` left the `.old-<random>` of a killed install
- macOS: clonefile kept a file already at the destination -> replaced (a
nested package could hold two versions' files)
- Package was hoisted next to an out-of-range version of its peer
(#36300; fixes #20376)
- Dep nested under a package with `bundledDependencies` resolved the
bundled version (#43377; fixes #43351)
- After a version bump the old version of a transitive dep stayed at the
root (#41053)
- Required peer that a migrated lockfile left unbound stayed unbound
(#39343)
- Tree saved after a ranged peer gained a higher candidate differed from
the next install's (#38767)
- `file:` override on a registry package's or transitive dep was not
linked or resolved from the wrong directory -> from the project root,
linked with its deps (#38994, #44339; fixes #44299)
- One `file:` folder that cannot be hard-linked (EXDEV) switched all
later packages to copyfile (#40663)
- Failed optional dep left its `.bin` links (#44931)
#### Isolated linker, global store
- `node_modules` or entry that is a mount point (Docker volume) is kept
and reset in place
- `bun add -g` never linked bins into the global bin directory (#30451;
fixes #28597, #30450)
- Optional dep whose tarball cannot be downloaded or is corrupt failed
the install -> skipped with a warning, also `--offline` (#43229; fixes
#43212)
- `node_modules/.bun/node_modules` changed between installs of one
lockfile with `npm:` aliases -> links named by the dep, one layout
(#40356; fixes #40355)
- Packages that are peers of each other were installed twice (#29345;
fixes #29343)
- Missing `link:` target was accepted -> install fails, as hoisted
(#38045)
- Registry package's own `file:./vendor/x` dep failed -> linked from
inside the package (#38856)
- Workspace's scripts ran before the root's deps and bins were there ->
after everything else; a bin such a script writes is linked for every
dependent (#44868)
- Empty directory, or one without package.json, in a link slot stayed
(#41453)
- Store names of non-ASCII paths were garbled (#40719)
- Package used under its name and an alias got bins for one dependent
only (#44446)
- `--omit=peer` dropped a peer an ancestor provides; `bun prune
--omit=peer` agrees (#41416)
- Files deleted from a `file:` folder stayed in its copy (#37138)
- Links of a renamed or removed workspace stayed in `node_modules` (both
linkers) (#38511)
- `bun prune` left dangling links to removed optional / peer deps in
store entries (#42625)
- Switching the global install's linker removed `bun link` registrations
(#43582)
- Global store: a package whose peer is typed by the project's
`@types/*` was shared, TypeScript missed the types -> project-local
(#36796; fixes #36795)
- Ranged peer whose auto-installed version drops out of the saved tree
was linked to nothing (#38768)
#### Bins
- Hoisted: with `--silent` a failed bin link exited 0 and saved the
lockfile -> 1, nothing saved (#44997, #44958)
- Every install recreated `.bin` links, failed with `EEXIST` on a
read-only up-to-date tree -> a right link is left alone (per bin: chmod
1 -> 0, unlink 1 -> 0, symlink 2 -> 1) (#36701, #20067; fixes #14736)
- Several packages with one bin name: an arbitrary one won -> direct
deps first, then registry / git / tarball before workspace, `file:`,
`link:` packages, then by name (#31416, #41867)
- Isolated made bin targets 0777 -> `0777 & ~umask` (#41509)
- One bin that fails to link stopped the rest (#38972)
- `bin` entry whose value is not a string dropped the package's other
commands (#43159; fixes #43148)
- File system that refuses symlinks (EACCES / EPERM) failed the install
-> one warning, no `.bin` links (#40161)
- Bare `bun update -g`/`bun ci -g` linked no bins; a reinstalled global
package gets its command back (#43384)
- `bun pm migrate`/`pm trust` wrote uninitialised bin bytes into
`bun.lockb` (#37581)
#### bun.lock, bun.lockb
- Corrupt or crafted `bun.lockb` crashed or hung install, `pm ls`,
`why`, `outdated` -> validated at load, refused with a warning; files by
Bun 0.x are normalised and keep loading (#32753, #39720)
- Two strings whose hashes collide became one in the lockfile (#41642)
- Root `file:` or registry dep named like a workspace made Bun write a
lockfile it refuses (`Duplicate package path`) -> the member beats
`file:`; a registry range it does not satisfy gets the root slot
(#37245, #37248)
- Root alias of the registry package named like a workspace dropped the
workspace (#43567)
- `file:` paths from the lockfile were resolved from the wrong directory
after `bun update` or an override removal (#38850)
- Re-resolving install dropped packages `bun.lock` holds only through
optional peers (#39002)
- Package printed at several paths got its edges from the wrong row
(#39347)
- Re-saving moved a bundled peer off its entry's version, and a peer
nothing satisfies (#38837, #38892)
- `bun add` installed nothing when `bun.lock` repeats a dependency line
(#43271)
- `--lockfile-only` saved after an error; `--silent` failed on a
`bun.lock` it ignores (#44364)
- `bun.lock`, `bun.lockb`, `yarn.lock` ignored the umask (`yarn.lock`
0666) (#41808)
- `bun <path>.lockb` printed the directory's lockfile, read `.env`,
needed package.json -> prints the given file (git textconv works)
(#44870)
- `git+git://` resolutions did not load back from `bun.lock` (#38798)
- `bun pm migrate`/`pm trust` wrote another
`configVersion`/`patchedDependencies` than install; yarn entries without
`#sha1` (#41908; fixes #38193)
- Absolute or over-long workspace path in `bun.lock` / pnpm-lock.yaml
crashed or counted as pruned (#43405)
- `bun install --yarn` rewrote an unchanged `yarn.lock` every time
#### --frozen-lockfile, bun ci
- `bun ci` failed in a workspace when nothing changed (member with a
script and a `latest` row); one member's edit moved pins elsewhere ->
members are compared row by row, keep their pins (#44919; fixes #26070)
- Version the lockfile pins was blocked by `minimumReleaseAge` (#40032;
fixes #40031)
- After a migration with a root postinstall, or `pm migrate` to
`bun.lockb`, the next frozen install failed on the meta hash (#44501)
- With both `overrides` and `resolutions` only `overrides` applied ->
both; a lockfile without those rules fails frozen, 1.4's too (#38811)
- Direct dep pinned outside its unchanged range (one-sided merge) was
installed, frozen passed -> re-resolved; frozen fails (#43375; fixes
#43795)
#### Migrations (npm, pnpm, Yarn v1)
- Yarn Berry: a range `yarn.lock` has no key for is the workspace that
satisfies it; Yarn's own `packageExtensions`; `resolutions` keyed on an
alias; a name in several groups of a workspace; `catalog:` in an
extension; `%xx` in a folder name; clearer refusals (#45052)
- Yarn v1, npm: a dep the lockfile has no entry for is reported (#45052)
- npm: a scope registry with a path and no trailing slash gave
`InvalidNPMLockfile` (#38698)
- npm: a package's own `file:` directory was resolved from the project;
one that climbs out is skipped (#38990)
- npm: a `file:` directory copied by `--install-links` failed with
EISDIR (#43103)
- pnpm: `pnpm-workspace.yaml` was read only with a migratable lockfile;
`bun patch --commit` then segfaulted (#38754)
- pnpm: the `pnpm` block was removed from package.json -> kept, fields
copied (#38775)
- pnpm: `onlyBuiltDependencies` was lost -> `trustedDependencies`;
isolated reports blocked scripts (#38780)
- pnpm: importer rows differed from a package.json parse, the next
install rewrote `bun.lock` (#38791)
- pnpm: only used catalog entries were migrated (#38829)
- pnpm: non-string keys / values in `pnpm-workspace.yaml` crashed ->
scalars copied as written (`react: 18` -> `"18"`) (#44470)
- Read-only commands and failed installs wrote a migrated lockfile and
package.json edits -> only a command that saves a lockfile (#38804)
- Yarn v1: workspace packages were dropped when the root has no deps
(#38878)
- Yarn v1: `npm:` alias packages were named after the tarball URL
(#38948)
- Yarn v1: registry entries without `resolved` failed (#38985)
- Yarn v1: an entry without a buildable resolution aborted the migration
-> skipped with a warning (#39001)
#### Workspaces, catalogs
- Member without a `name` failed the install -> skipped (#38781; fixes
#6317)
- Dist-tag (`latest`, `""`) on an unpublished sibling got a 404 -> links
the workspace (#35468; fixes #4830)
- Empty `workspace:` spec linked the project into itself -> error; a
glob like `../*` made the root its own member (#41653)
- Workspace globs skipped symlinked member directories (#41567)
- Range linked to a workspace stayed linked after the root dropped it
(#43468)
- Workspaces of a package.json in `/` (or `C:\`) were not found (#43404)
- `workspaces` glob that fails named no path (#43517)
- `bun update <name>` rewrote `workspace:^`, `file:` and other
non-registry entries (#38847)
- `bun add member@workspace:^` lost the spelling (#38866)
- `bun update` printed no row, or another catalog's version, for a moved
catalog entry (#38763)
- `bun update -i` updated one of several catalogs defining a package ->
a row per catalog (#36446)
- Failed `catalog:` dep always suggested `bun add --catalog` -> only
where that works (#44638)
- `npm run <script> -w <ws>`/`--workspaces` inside a script recursed
forever -> runs the workspace's script (#33800; fixes #22719, #24838,
#33796, #41543)
#### Overrides, peers
- Auto-installed peer took the newest version of one asker -> newest
that everyone asking accepts (#36646; fixes #8292, #15711)
- `*` peers resolved by manifest arrival order -> after their siblings;
unprovided peers in a fixed order (#37713)
- `incorrect peer dependency` was checked against any copy in the tree,
hoisted only, every install -> the copy each dependent resolves, both
linkers, only when something was resolved (#41936; fixes #7403)
- Peer that a `file:`, `link:`, tarball or git dep provides was looked
up in the registry (#33156)
- Peer dependency on `bun` downloaded the `bun` npm package (80-170 MB)
-> optional (#39757)
- `minimumReleaseAge` blocking a peer or optional pin failed the install
-> warning (#38995)
- `bun update name@version` bound a peer row to a stale lockfile
leftover (#38901)
- Override replaced the link to a member of that name (#37271)
- Changing `overrides` / catalogs re-resolved rows a package no longer
owns (#38849)
- `bun update <name>` left rows of a `$name` override stale, frozen
passed (#43981; fixes #43975)
- `bun update --latest` moved versions an override selects; `-r` wrote
`"latest"` into package.json (#44485)
- `overrides`/`resolutions` that are not objects were ignored -> error
(#40729)
- Keys `foo@catalog:`, `my-foo@npm:foo[@^1]` (Yarn) were ignored with a
warning
#### Registries, credentials, .npmrc, bunfig
- `.npmrc` credentials follow npm's key walk: `//host/` covers paths
below it, `_auth` sent as written, a line reaches registries named by
`--registry` / env / `$VAR`, a tarball on another https host gets that
host's line; a sibling or look-alike path inherits nothing; `:443`/`:80`
keys keep working (#40423; fixes #28233, #30311, #30513, #40549)
- Registry URL without a trailing slash lost its last path segment
(#36294; fixes #5368, #14017, #16185, #20373)
- `user:pass@` in a registry URL from an env var was dropped (#38834)
- `user@`/`user:@` sent nothing -> Basic auth with an empty password
(#39063)
- URL credentials were sent percent-encoded -> decoded (`p%40ss` sends
`p@ss`) (#39603)
- `.npmrc`: `;`/`#` comments were part of the value; `ignore-scripts=1`,
`=True`, empty did nothing -> as npm (#41916)
- `.npmrc` keys and values kept Unicode whitespace (#41714)
- `--ca`/`--cafile` were shadowed by a config file's `cafile` -> one
setting, a later layer replaces both (#41898)
- `-g` commands ignored `globalDir` from `--config` and `~/.bunfig.toml`
(#35454; fixes #4553; refs #12886)
- `~` in `cache.dir`, `globalDir`, `globalBinDir`, `cafile` was a
literal directory (#36667; fixes #10152, #26715)
- `[install.cache] disable = true` still cached manifests (#36219)
- Unreadable `.npmrc` / bunfig.toml was skipped silently -> warning
(#41693)
- `bun publish`, `pm whoami`, `audit`, `pm view`, `pm diff` ignored
`http_proxy` and `NODE_TLS_REJECT_UNAUTHORIZED=0` (#38075, #38093)
- `bun pm whoami` sent a stub CI name -> the real vendor
(`ci/github-actions`) (#40805)
#### Network, retries
- Retries came at once, one network error halved concurrency -> 250 ms
doubling to 10 s with jitter, `Retry-After`, 429 / 408 retried,
certificate errors not (#40009)
- Timed-out request was retried silently -> a warning per retry (#35168)
- `BUN_CONFIG_MAX_HTTP_REQUESTS` was ignored (#38744)
- Help and docs said `--network-concurrency` defaults to 48 -> 64
(#38759)
#### Cache, tarballs, extraction
- Process could exit before the manifests it fetched were cached:
`--offline` right after an install could fail
- `file:` / URL tarballs were cached by path or URL, two projects or
branches got each other's package -> by the integrity in `bun.lock`
(#39016)
- `file:` / URL tarball deps were reinstalled on every run (hoisted) ->
verified by a `.bun-tag` (#35576; fixes #8260)
- `--force`, `bun update`, re-adding the same path / URL kept old bytes
or the old hash -> direct tarball deps are fetched again (#31868; fixes
#31864)
- Re-extraction leaked the displaced cache folder; extraction
directories stayed in `$TMPDIR` (#38702, #33979; fixes #33977; refs
#28062)
- Two registries on one host (port, path, http) shared cache entries
(#41636)
- Concurrent installs sharing a cache deleted each other's entries
(ENOENT without `RENAME_EXCHANGE`, NFS) -> first writer wins (#36229;
fixes #36227)
- Gzip trailer was not verified (since 1.3.14) -> a damaged tarball
fails; also `Bun.Archive` (#41503)
- Body that is not gzip installed as an empty package; a tarball without
package.json stayed in the cache
- Query string / fragment of a tarball URL ended up in the extraction
folder name (#39011)
- `github:` tarballs extracted symlink entries -> skipped, like npm
(#31481)
- Rewriting a cached manifest unlinked it first -> atomic replace
(#38916)
- `--no-verify` cached unchecked bytes under the lockfile's hash, for
all projects -> own key; isolated kept such a copy
#### git, GitHub, folder deps
- Cached git dep never saw tags / branches pushed later; `bun update`
follows moved refs (#35566; fixes #11548, #13769, #15336, #18947)
- `git+ssh://git@host:2222/..` lost its port in the ssh fallback
(#36932; fixes #36931)
- `deploy@host:org/repo.git` became `git@deploy@host` (#35026)
- `bun add name@git+ssh://host/repo.git` lost the alias for hosts other
than GitHub (#36687; fixes #13891)
- `github:o/r#feat%2Fx` silently installed the default branch; an
escaped owner / repo is an error (#43172)
- Optional git dep that cannot be cloned or lacks the ref failed the
install -> skipped with a warning, also when locked (#43076, #43352;
fixes #43350)
- Several `github:` / git refs on one commit, or a `file:` folder
declared by several packages, failed with EEXIST or wrote a lockfile Bun
refuses -> one package (#42640, #42545)
- Concurrent cold installs replaced each other's git cache folder
(#42656)
- `GIT_DIR` (git hooks) made install and `bun create` work on another
repository -> 13 git variables are not passed on (#41715)
- `file:` folders declared by git / tarball packages were resolved from
the project (#38816)
- Bare word or `git@host/path` was handed to `git clone` as a local
path; a URL could be read as an option
- `bun link -g`/`unlink -g` failed; `bun link -g <name>` removed the
registration -> `-g` is ignored (#33142; fixes #21397, #33141)
#### Lifecycle scripts, trust
- Hoisted: beyond `--concurrent-scripts`, the next script waited for all
running ones to end -> for one
- Failed or unstartable script left other packages in place whose
scripts never ran, and never would -> removed
- `trustedDependencies` entry added to a member after the first install
did nothing -> its blocked scripts run once (#41803)
- Isolated: a package trusted after it was installed never ran its
scripts (#41845)
- Package installed through an `npm:` alias could not be trusted
consistently -> by its real name in package.json, `--trust`, `pm trust`,
`bun.lock` (#39443)
- `bun pm untrusted`/`trust`/`ls --trusted` followed a stale lockfile,
knew nothing with `bun.lockb` -> read package.json (#41933, #34327)
- `pm untrusted`/`trust` listed and reran workspace members (#41513)
- Failing script of a package both optional and required deleted the
package, exit 0 -> install fails (#43218; fixes #43211)
- `--concurrent-scripts` did not apply to the isolated linker (#42445;
fixes #42421)
- bunfig `concurrentScripts` beat `--concurrent-scripts` (#42422)
- Node-gyp shim was unreachable when the temp directory falls back to
the cache (#38098; fixes #38079)
- `--help` said dep scripts never run -> `--ignore-scripts` also skips
trusted ones (#38893)
- `bun pm -g untrusted` suggested `bun pm trust` -> `bun pm -g trust`
(#44663)
- After a failed script, a half-deleted git / tarball / patched package
counted as installed
#### Security scanner, audit
- Scanner saw registry packages only -> every resolved dep (git, GitHub,
tarball, `file:`, `link:`), URLs without userinfo / query; a fatal
advisory stops them before install and scripts (#37590)
- `--production`/`--omit=dev` failed when the scanner is a devDependency
(#31031; fixes #31028)
- Scanner process loaded `.env` itself -> gets the install's
environment, follows `--env-file`, `--no-env-file`, `env = false`
(#44845)
- `bun audit fix` could downgrade into an older major (#39317)
- `bun audit --help` lacked `--production`, `--omit`, `--dry-run`,
`--cwd` (#38836)
#### add, remove, update, outdated, link
- Hoisted: `bun remove foo` deleted the `node_modules/foo` another
workspace has for `"foo": "npm:bar"`
- `link`, `install <pkg>`, `install --analyze`, `update -i`, `remove`
exited 0 after `Failed to install N packages` -> 1 (#44989)
- `bun add ../path` from below package.json, `bun install -g .` resolved
from the wrong directory -> the cwd (#43348, #36623; fixes #5682)
- `bun add <folder | tarball | git url>` of a declared package wrote it
twice (#43380; fixes #8031)
- First `bun add -g` used a package.json above the global directory
(`~/package.json`) (#30659; fixes #40683)
- `bun add --dry-run` in an empty directory created package.json
(#36694; fixes #13244)
- `bun remove` reordered package.json keys -> order, tabs, final newline
kept (#35586; fixes #7215, #9351)
- `bun remove -g` left dangling links in the global `node_modules/.bin`,
deleted foreign dangling links in the bin directory (#43403)
- `bun update <name>` blanked an optional / peer range no version
satisfies (#43195)
- `bun update` that only rewrites package.json said `(no changes)`
(#38918; fixes #38908)
- `bun update -i` repeated its prompt on mouse clicks and in short
terminals (#39683)
- `update -i`/`outdated` tables were sized in bytes -> display width
(CJK, emoji), cells escaped (#43333, #43236)
- `outdated`/`update -i` used the lockfile's ranges -> package.json's
(#42005)
- `bun outdated a b` needed all patterns to match -> union; `!pattern`
removes (#43309)
- `outdated`/`why` knew an aliased dep by one name -> either, both
printed (#43338)
- Coloured version diff dropped the build tag, left a tag that only
grows (`rc.1` -> `rc.10`) dim; long prerelease tags were garbled
(#38688, #38649)
- `minimumReleaseAge` error swapped range and name (#37895)
- `bun link`/`unlink --help` described a wrong `--save` default (#38915)
#### bun pm, why, info
- `bun pm pkg get` of several values altered one with a `}` in it, left
a key unescaped (#45061)
- `bun pm cache rm --cache-dir <dir>` cleared the global cache ->
`<dir>`; project config still cannot redirect it
- `bun pm bin -g`/`pm ls -g` failed before any global install -> work,
write nothing (#36622; fixes #6382, #7501, #13019)
- `bun pm cache rm` says when the global store goes with the cache; docs
name `--force` for stale manifests (#43667)
- `bun pm version` saw no repository in worktrees / submodules (`.git`
is a file) (#41754)
- `bun pm version prerelease` overflowed above 2^32; versions npm calls
invalid were accepted (#42459)
- `bun pm view pkg@tag`/`pm diff` used `latest` for an unknown dist-tag
-> error listing the tags (#42063)
- `bun pm`, `pm --help`, an unknown subcommand printed three help texts,
unindented, without `pm diff` and `ls -g` -> one (#39487, #43314,
#43098; fixes #43310)
- `bun pm bin -g` said `not in $PATH` for an entry with a trailing slash
(#28773; refs #28771)
- `bun why` printed a package's dependents at every occurrence
(exponential) -> once, repeats `*deduped` (#37922)
- `bun why name@version` failed for exact / scoped names, ignored a
workspace's version (#43284, #43290; fixes #43288)
- `bun why`: no-match error on stdout -> stderr (#43287; fixes #43285)
- `bun why`: branch left open after the last visible workspace dependent
(#43292; fixes #43291)
- `bun why`: a cycle back to the queried package is `*circular` at its
first repeat (#43300; fixes #43295)
- `bun why`: a root package.json without `name` was missing as a
dependent (#43277)
- `bun why`: a peer dependent was shown under the wrong copy (#41941)
#### pack, publish
- `workspace:`/`catalog:` versions came from `bun.lock` (stale, or
failed without one) -> the package.json files; no lockfile is read
(#38813; fixes #20477, #20829)
- `workspace:` aliases and directories were published as written ->
`npm:` aliases; the workspace's version (#38788, #38835)
- `!pattern` in `.npmignore` could not re-include files below an
excluded directory (#36699; fixes #15602)
- Relative `--destination`, `--filename`, `bun publish ./x.tgz` were
resolved from the package root -> the cwd (#38739, #38704)
- Failed pack left a partial tarball, `publish --dry-run` deleted an
existing one, a FIFO `--filename` hung -> built in memory, written once
complete (#38721)
- File names that are not UTF-8 were mangled, two became one entry
(#38715)
- File systems whose readdir reports `DT_UNKNOWN` lost entries (#38716)
- `bin` paths naming no file, `..`, a trailing slash in
`directories.bin` broke pack; an empty `bin` hid `directories.bin`
(#38720)
- File under several `bin` names was packed several times (#41291)
- Directory, bin or bundled dep that is there but unreadable was left
out silently -> exit 1 (#44400, #44873)
- `bun publish` accepted a `version` that is not semver -> refused after
the scripts; `v1.0.0` goes out as `1.0.0` (#43142)
#### bun patch
- `--commit` from a workspace member flipped the root package.json's
final newline to the member's
- Patch adding a file in a new directory failed with `EACCES` for
non-root users (#33573; fixes #13330, #33571, #38569)
- Hunks were applied by line number, wrote wrong text when the file had
moved; `-U0` hunks landed a line off -> placed by context like `git
apply`; `hunk #N does not apply` fails the install (#41733, #41695;
fixes #38879)
- Old-style diffs whose hunks delete lines starting with `-- a/` were
misparsed (#34870)
- Failed copy, missing cache entry, missing git or failed `git diff`
left a partial or no `node_modules/<pkg>` -> staged copy, everything put
back (#43188, #43160; fixes #43164)
- `bun patch` dropped the package's bundled and nested deps, `--commit`
recorded them as deleted (#43178)
- `bun patch` of a bundled dep deleted the bundled copy -> refused
(#43199)
- `bun patch` of a `file:` folder, `link:` or workspace package damaged
`node_modules` -> refused (#43223; fixes #43200)
- `bun patch <path>` replaced a folder with another version -> refused
when the version is not locked (#43367; fixes #43353)
- `npm:` alias could not be named by its package; a second `bun patch
<alias>` lost the first patch (#43382)
- Isolated: `bun patch <transitive>` made a stray `node_modules/<name>`
-> edits the store entry (#43383)
- `bun patch` replaced workspace links and symlinks above the package,
could write into the global store -> links stay; anything under the
cache is refused (#43406)
- `--commit` on a patched package wrote `.bun-tag` files and cache paths
into the patch, read `/etc/gitconfig` (#44349; fixes #19327, #44320)
- `--commit`: a new binary file became empty, a changed one was skipped,
exit 0 -> commit fails
- Member's `patchedDependencies` were ignored silently -> warning
(#39869)
- Isolated: `bun patch` replaced `node_modules/<pkg>` by a directory
that could not load its deps -> edits a copy in the store entry, the
link stays; global store: `--commit` restores the link (#43365)
#### bunx
- `bunx pkg@latest` relinked everything each run, a day-old tree was
refreshed every run -> once; served with a warning when the registry
gives no answer (#41226; fixes #23597, #41211)
- Several `bunx <pkg>` at once corrupted the shared install -> file lock
(#37851; fixes #37830)
- `directories.bin` was resolved from the wrong directory (#39096)
#### bun create
- Windows: a GitHub template silently overwrote files (its conflict list
was always empty) and wrote through junctions -> listed; `--force`
replaces the link
- `bun create <local template> <dir>` deleted an existing directory ->
merges, lists conflicts (links in the destination too), overwrites only
with `--force` (#36351; fixes #27948, #36341)
- `git init` / commit raced tasks and install -> finished first; the
first commit holds exactly the template (#41342; fixes #36953)
- `bun-create` tasks ran without a shell, not at all without deps,
failures ignored -> run like package.json scripts, with
`npm_package_name`; a failing task stops with its exit code (#41598,
#38955)
- Failed nested `bun install` was ignored -> exits with its code
(#38485)
- Absolute template path crashed -> local folder; `.`, `..`, an empty
name are refused (#41770)
- `bun create ./Component.tsx` overwrote your stylesheet,
`styles/globals.css`, `lib/utils.ts` -> kept and listed; `--force`
overwrites (#44668)
- Template's package.json indentation was lost (#36965; fixes #36964)
- Missing-export hint printed `{{` `}}` (#37847)
#### Auto-install
- Timers and I/O callbacks ran inside `require()`, `import()`,
`Bun.resolveSync()` while a package was fetched -> the thread waits; git
deps are no longer cloned at run time (#36159; fixes #43842)
- Second version (`pkg@2` after `pkg@1`) with the manifest in the disk
cache failed with `Unexpected` (#36659; fixes #10411)
- Failed lookup failed until the process exited -> a 404 stands as long
as a cached manifest (5 min, or its `Cache-Control`); any other failure
is asked again once the event loop has gone around (#42883)
- Failed download limited `fetch()` to 4 concurrent requests for the
rest of the process (#42945)
- `--prefer-offline` still asked the registry -> cached manifest
(#36776)
- Resolve errors did not say why (#38180)
- bunfig `install.prefer` worked for `bun run <file>` only -> also `bun
<file>`, `bun test`
- Dep whose name or version has a JSON escape fell back to `latest`
#### Completions, installer
- Second completions line was added to a `.zshrc` that already sources
`~/.bun/_bun` (#35561; fixes #10897)
- fish completions went to `/etc` when `~/.config/fish/completions` is
missing (#41659)
- install.ps1: the `another bun.exe is already in PATH` check never
fired (#38567)
#### Crashes, panics, hangs
- Hang until out of memory on a dependency cycle -> `dependency cycle
cannot be laid out in node_modules`, exit 1; a bundled back-edge
installs (#38976)
- Hang: a dangling `node_modules/@scope` symlink (hoisted)
- Hang: `--concurrent-scripts=0` -> the default (#42379)
- Hang: isolated, a tarball URL that cannot be requested (`ftp://`)
(#39672)
- Hang: isolated, cold cache, a git dep that is scp-form, a peer, from
`overrides` or spelled differently in `bun.lock`; after a failed clone /
checkout (#44448, #37156, #43075)
- Panic: paths that do not fit the path buffer in both linkers' walks,
`link:` targets, long linked names, `<alias>/package.json` ->
`ENAMETOOLONG`/`Invalid dependency name` (#37424, #37400, #38369,
#38571, #38575)
- Panic: over-long `--cafile`, `--cwd`, `add --filter`;
`$BUN_INSTALL`/`$HOME` with `-g`; bunx bin names; pnpm `link:`/`file:`
paths; progress bar names (#41702, #38413, #37394, #43537, #38558)
- Abort of all package manager commands, `bun run`, `bunx` in a cwd
within 13 bytes of `PATH_MAX` -> `ENAMETOOLONG`, or the file counts as
unreadable (#42502)
- Panic: `outdated`, `update`, `update -i` on a `bun.lock` without
`packages` (#41647)
- Segfault: package.json nested ~8,400 levels; a deep YAML alias chain
in pnpm / Berry files
- Panic: all `bunx` install flags at once
- Use-after-free in `bun add --trust` and at the end of an isolated
install (#31245, #39640)
- `Bad system call` on Android / Termux (`openat2`, `fchmodat2` under
seccomp) (#39084)
#### Windows
- Bins whose shebang uses `env -S` did not run (#31391; refs #22422,
#27924, #31387)
- `.bunx` shims broke when the package is on another drive (#38018)
- `bun remove` left `.bunx`/`.exe` shims (#35585; refs #11970)
- `bun install` failed in the root of a drive (#43437; refs #29273)
- `EINVAL: Failed to replace old lockfile` on exFAT / FAT32 (#33029;
refs #10169)
- Concurrently published cache entry was deleted; renames failed while a
virus scanner holds a new file -> retried for 5 s
(`BUN_INSTALL_WINDOWS_RENAME_RETRY_MS`) (#33884, #35568; refs #11250,
#28062)
- `bunx.exe` was written when the hard link fails -> `bunx.cmd` (#35686)
#### Performance
User-space instructions of `bun install` (`perf stat`, median of 3,
millions), generated project of N packages, loopback registry; warm =
nothing to do, relink = cache + lockfile, no `node_modules`.
| | main N=400 | branch N=400 | main N=1600 | branch N=1600 |

System calls per package (`strace -c`, slope between 100 and 300
packages of 31 files). Per run: a few more `lstat` (change 8), one read
per `file:` directory dep.

#### Internal, no user-visible effect
- Earlier fold of 171 PRs is the first layer; 12 of them were taken out
again (#39403)
- One implementation each: trusted set, required-dep predicate,
failed-optional discard, bin linking, package.json walk, `--cwd`, cache
publish, specifier -> version (was 4), lockfile writer, registry request
- `pack()` consumes its context; one `binding.gyp` predicate; Yarn v1
migrator 2,032 -> 888 lines, no `unsafe` (#37670, #43912, #37539,
#38303, #37865)
- Debug builds: opt-in stack dump, `node` shim directory kept, manifest
cross-check deleted (#37335, #37384, #43170)
- Binary size pass (outlined helpers, shared flag tables, index sorts):
+464 KB -> see Performance; dead auto-install disk scan removed.
`unsafe` in src/install: 585 -> 540
#### Test-only PRs

#40198 #40450 #39956 #39740 #41110
- Exact output / lockfile / layout (nested-overrides, bun-add-filter,

#39648 #39746 #40452 #40454 #40456 #41118

cache, un-awaited matchers): #34175 #41401 #41591 #38858 #39190 #38627
#37333 #33279

#### Taken in part (what is in. Not: what is not)
- #19637: opt-in `bunx --trust` (runs the scripts of the package and its
whole closure). Not: trust by default

prune`)

equivalent spellings (refs #22689)

blocked. Not: change 18
- #42030: a plain install re-reads a `file:` directory's package.json.
Not: failing frozen (warns)
- #42039: change 8; `bun prune` refuses a linked `.bun`. Not: the root
link (on purpose); a package's own directory on a warm run
- #42052: `bun pm view`/`info`: no project needed, several fields, npm
paths (`maintainers[0].name`), semver-sorted `versions`, `bin:`,
`DEPRECATED`. Not: new `--json` errors (refs #20673)

materialising symlinked cache entries; #43788 unverified

another drive (never run). Not: a missing `%TEMP%` (warning) (refs
#44033)
- #44406: change 4. Not: a copy no loaded lockfile names
- #44488: a dep's script finds its own `.bin`, then `PATH`, then shared
`.bin`: another package's bin cannot shadow `node`/`sh`. Not: bins per
script owner
- #44641: its install test and docs hunk. Not: 13 HTTP / fetch test
files
- #44793: Windows: the launcher of a `.cmd`/`.bat` bin (any case)
refuses cmd.exe special characters. Not: `bun run <bin>.cmd`
- #44798: a `node_modules` a git dep commits is dropped unless it
bundles (then without links). Not: bundled closure only

### How did you verify your code works?
- Suite (offline, root): main's tests on main 146 files, 9,099 pass, 306
fail; this branch 174 files, 16,067 pass, 42 fail; 6,277 passing tests
are new, 268 that fail on main pass. Of the 42, 40 fail on main too; 1
needs Docker, 1 test deps.
- Absorbed = a test here covers the claim, passes here, fails on main.
Exceptions: test-only PRs, guards, performance PRs (measured); by
reading only: #39640 #37335 (no test possible), #34175 (Docker), #38858
#39190 #41401 #41591 (flakes), #40447 #39740, the refactors.
- Randomized differential: 600 generated projects (every dep kind, both
linkers, both lockfile formats) through installs, edits, prune, patch,
damage, kills; all output compared. First install succeeds: 545 -> 559.
Projects that violate an invariant:
| | main | this branch |
|---|---|---|
| repeated install rewrites files | 265 | 10 |
| repeated install reports work | 101 | 2 |
| repeated install changes the tree | 22 | 3 |
| lockfile depends on manifest arrival order | 57 | 0 |
| exit code depends on the linker | 20 | 0 |
| writes outside the project | 21 | 0 |
| declared dep cannot be resolved | 13 | 1 |
| dep resolves to a wrong version | 4 | 0 |
| frozen / relink / cold cache fails on its own lockfile | 7 | 0 |
| package.json rewritten with the same bytes | 7 | 0 |
| crash or hang | 3 | 0 |
| dangling symlink | 2 | 0 |
| bin not executable | 2 | 2 |
| leftovers in the temp directory | 230 | 1 |
| tree or exit code after kill + reinstall differs (timing) | 3 | 4 |
- Credentials: 805 requests with main, this branch, npm 11.17.0: 534 as
main; 170 wider (npm too in 140, 30 deliberate); 82 narrower; 19 another
credential. 142 non-http(s) registry URLs x 16 routes: no request (main:
66).
- Secrets: a secret in every input of 698 projects x 6,490 commands, not
masked: data asked for on stdout, source excerpts under a diagnostic,
echoed arguments.
- Lockfiles: 90,000 mutated `bun.lockb` x 7 commands: no crash or hang.
- Version picking: npm-pick-manifest 11.0.3 over 200,000 generated
pairs: differs only for a dangling written `latest` and `^1.0.0-a.0`.
- Debug + ASAN: 9 files (1,253 tests); 200 rounds of #31245's race. Two
installs at once, 252 packages: tree right in 150 of 150 rounds, 2 of
300 exit 1 (main: 35 of 40 wrong, 69 of 80).
- Hoisted thread pool vs main thread, one binary: 704 generated
projects, 8,800 fuzz cases, CPU starvation x 4 backends, 432 injected
I/O errors, thread and fd limits, script order: equal.
Not verified:
- Windows, macOS: CI only. Android (#39084): a seccomp filter on Linux,
no device.
- By script, no test: `--trust` with an alias, an aborted upgrade leaves
no holes, two installs at once. overlayfs: a simulated `EXDEV`.
- Known limits: change 19.

RequiredPackages, which walks the linked dependencies from the root, for both linkers.entry_is_requiredhere is the conservative form: it ORs the lockfile edges of every package in the store onto a package id, so an entry that a required edge reaches still fails, as on main. It cannot use the store's own edges: early dedupe in the store build gives a second dependent the first dependent's node, and that node keeps the first edge, which can be the optional one. install: --offline does not fail on what is below a skipped optional dependency #43185 changes the--offlinehandling of the same four arms.

The--offlinearms for the isolated linker are the subject of install: --offline does not fail on what is below a skipped optional dependency #43185. Round 3: a parent in the global store keeps its links to a missing entry, and an optional peer edge does not require an entry. Round 4:unlink_links_toscans the dependency lists (a public hoist adds the entry to the root's list only), and only root, workspace and folder entries drop the link, so a store entry's relink stays unchanged. Round 5:entry_is_requiredreads the lockfile edges per package instead of the store's edges, and three tests cover the shared download for the isolated linker, in both orders, fresh and from a lockfile (the hoisted linker has the same hole on main, install: fail when an optional and a required dependency share a failed download #43197 covers it).Checked 1 install across 2 packages (no changes). The one install is the root entry, which the isolated linker always counts as skipped. That line is the existing output for an isolated install where nothing needs a link.is_network_task_requiredreturns true for a task id that is not in the map (a local tarball). Those keep the error path.missingentry, insidenode_modules/.bun/<entry>/node_modules/.
