Problem

  • bun pm diff reads a local folder as bun pm pack would publish it, but inserts its package.json as the raw bytes on disk (src/runtime/cli/pm_diff_command.rs:616). Pack first replaces workspace: and catalog: dependency versions (edit_root_package_json in pack_command.rs).
  • So a workspace package never matches its published copy. bun pm diff pkg.tgz . right after bun pm pack reports a package.json change and ! dependencies pmdiff-b: ^1.0.1 → workspace:^. The default bun pm diff does the same.

Fix

  • The resolution moves out of edit_root_package_json into published_version(lockfile, name, spec). Pack and bun pm diff both call it. Pack keeps its three error messages.
  • Against a tarball or a registry version, bun pm diff replaces only those version string tokens in the folder's manifest. A version that does not resolve stays as written. Two folders compare as written, so the patch between them applies to the files on disk.
  • The lockfile is the nearest bun.lock above the folder that lists it as a workspace, else the folder's own. That is the lockfile pack reads in that folder. It loads only when the manifest contains workspace:, catalog: or a JSON escape.
  • Verified: test/cli/install/bun-pm-diff.test.ts (the new case fails on 1.4.3, passes with the debug build). Also bun-pack.test.ts, bun-publish.test.ts, catalogs.test.ts. Self-reviewed: 3 concerns raised, 2 addressed, 1 listed under Notes as out of scope. The four bot review comments (JSON escapes, path normalization, lockfile precedence twice) are addressed.

Background

  • workspace:^ publishes as ^<the sibling workspace's version>. catalog: publishes as the range the root package.json defines. Registry consumers have neither, so pack rewrites both.
  • bun.lock records both (lockfile.workspace_versions, lockfile.catalogs).
  • A lockfile load resets the thread-local AST store, so read_dir_tree loads the lockfile before it parses package.json.
Notes

Repro (1.4.3 and main):

mkdir -p /tmp/pmdiff/packages/a /tmp/pmdiff/packages/b && cd /tmp/pmdiff
echo '{"name":"root","private":true,"workspaces":["packages/*"]}' > package.json
echo '{"name":"pmdiff-a","version":"1.0.0","dependencies":{"pmdiff-b":"workspace:^"}}' > packages/a/package.json
echo 'module.exports = 1' > packages/a/index.js
echo '{"name":"pmdiff-b","version":"1.0.1"}' > packages/b/package.json
bun install
cd packages/a && bun pm pack --quiet --destination ../../out
bun pm diff ../../out/pmdiff-a-1.0.0.tgz .
#   ! dependencies pmdiff-b: ^1.0.1 → workspace:^

Scope: dependency versions only. This PR makes the two commands share one resolver for dependency versions. It does not make pack-then-diff empty in every case. Three differences remain, and all three exist on 1.4.3:

  • Pack re-prints package.json (guessed indentation, expanded objects, decoded escapes). A minified or hand-formatted manifest still shows as formatting only on a terminal, and as a hunk in piped or --raw output, against its own tarball. Two existing tests rely on a local manifest being compared as written: a reformat-only release collapses to 'formatting only' and --json is one stable document. So this PR changes only the version tokens. A manifest in the printer's own format (2-space JSON.stringify) prints No differences.
  • Pack sets the executable bits on bin files in the tarball (add_archive_entry). The folder side keeps the mode on disk, so a bin file that is 0644 on disk shows old mode 100755 / new mode 100644.
  • Pack adds the files of bundledDependencies. The folder side does not, so they show as removed.

How a token is replaced. The JSON parser records the offset of each value. with_published_versions takes the string token at that offset, decodes it, checks that it is the value the parser returned, and writes the JSON-quoted published version in its place. A version spelled with a JSON escape ("workspace:\u005e") resolves too, as in pack (52c0511). A token that does not decode to the value stays as written.

Two folders. The first commit converted every folder. With two folders of which only one resolved (a second checkout, a git worktree), identical folders showed ! dependencies ws-b: workspace:^ → ^1.0.1, and 1.4.3 prints No differences. 9b4a2c5 tried a rule per dependency (skip a version that both folders spell the same way). Review showed that it mixes published and written versions in one hunk, so bun pm diff ./old/a ./packages/a > changes.patch no longer reproduced the right folder. 00d19c1 replaces it: two folders compare as written, exactly as in 1.4.3. An extracted tarball against the source folder therefore still shows ^1.0.1 → workspace:^, as on 1.4.3. Use the tarball itself for that comparison.

Which lockfile. lockfile_for walks up from the folder's parent and takes the nearest bun.lock or bun.lockb that lists the folder as a workspace. It goes past a lockfile that does not load or does not list the folder. When no lockfile above lists the folder, it uses the folder's own lockfile (the folder is a project root). A stray or broken bun.lock inside a workspace folder, or between it and the root, therefore does not shadow the project's, as in pack (a7dcd02, 0ea16f5). The result does not depend on the folder the command runs in: cd /tmp && bun pm diff pkg.tgz /abs/path/packages/a prints No differences. A folder that the nearest lockfile does not list (a vendored copy, a new workspace before bun install) keeps workspace:^ as written. workspace:1.x becomes 1.x in any folder, because pack needs no lockfile for it. A symlink that points at a member from outside the project stays as written, because the walk starts from the path as given.

Known limit: a stale bun.lock. "A workspace it lists" trusts the lockfile, not the root workspaces globs. If the root package.json stops matching packages/a and bun install has not run since, bun pm diff pkg.tgz ./packages/a still resolves workspace:^, while bun pm pack in packages/a fails. One bun install clears that state.

Cases checked by hand with the debug build (00d19c1): the member from inside (.), from the root (./packages/a/), from a sibling (../a), from /tmp with no project, from another project, the project root itself, a folder outside the workspaces globs, a symlinked path, a clone against the project, an extracted tarball against the source folder, two members with different spellings (workspace:^ → workspace:~). Checked on earlier commits and unchanged by the later ones: no lockfile, a corrupt lockfile (both stay as written, exit 0), a manifest with a BOM, a CRLF manifest, a key equal to its value ("workspace:^": "workspace:^"). On 52c0511: a manifest with no literal workspace: text (all four spelled work\u0073pace:). On 8ab8d69: absolute paths that are not normalized (/proj/packages/b/../a, /proj//packages/./a/, the root as /proj/packages/../).

Pack behaviour is unchanged. published_version holds the same rules in the same order: a bare ^, ~ or * takes the workspace's version from lockfile.workspace_versions, any other workspace: range is published as written, catalog: reads lockfile.catalogs. The three error messages keep their text. bun-pack.test.ts (86), catalogs.test.ts (89) and bun-publish.test.ts (46) pass.

Platforms. The new test passed on Windows x64 with the first commit's code. The later commits ran on Linux x64 only on my side (bun-pm-diff.test.ts: 47 pass, 1 skip). CI is green on 0ea16f5 on all lanes, Windows included (build 114565).

Related: #38813 changes where pack reads these versions from (the package.json files, not bun.lock). published_version is then the one place to switch for both commands.

…publishes them

A local folder's package.json went into the diff as the bytes on disk.
`bun pm pack` and `bun publish` replace `workspace:` and `catalog:`
dependency versions before they write the manifest, so every workspace
package showed a package.json change and a dependency note against its
own published copy.

The resolution moves out of `edit_root_package_json` into
`published_version`, which pack and pm diff both call. pm diff loads the
project's lockfile when the manifest uses either protocol and the folder
is the invoking package, the project root, or a workspace the lockfile
lists. It replaces only those string tokens. The rest of the file stays
as written, and so does a version that does not resolve.

Walkthrough

bun pm diff now compares package directories using packed representations when appropriate. It resolves workspace: and catalog: dependencies through applicable lockfiles, while directory-to-directory comparisons retain written contents. Workspace tests and documentation cover the behavior.

Changes

Published package comparison

Layer / File(s) Summary
Dependency version resolution
src/runtime/cli/pack_command.rs, src/parsers/json.rs
published_version centralizes resolution for workspace: and catalog: specifications. It reports distinct unresolved-version cases and exposes the JSON string-token helper.
Publication-aware diff materialization
src/runtime/cli/pm_diff_command.rs
bun pm diff selects publication mode, discovers applicable lockfiles, and rewrites dependency versions during package-directory materialization.
Workspace comparison validation
test/cli/install/bun-pm-diff.test.ts, docs/pm/cli/pm.mdx
Tests cover workspace and catalog transformations, lockfile locations, vendored packages, and folder comparisons. Documentation describes the published-version behavior.

Status: ready for review. CI is green on 0ea16f5 (build 114565).

Reproduced on bun 1.4.3-canary.1+4ff919377 (Linux x64) with the steps under Notes in the description. After bun install and bun pm pack in packages/a (which has "pmdiff-b": "workspace:^"), bun pm diff ../../out/pmdiff-a-1.0.0.tgz . shows "pmdiff-b":"workspace:^" on the folder side of the package.json hunk and the note ! dependencies pmdiff-b: ^1.0.1 → workspace:^. With this branch's debug build the folder side reads "pmdiff-b":"^1.0.1" and the note is gone. The same holds when the command runs from the workspace root, from a sibling package, or from a folder outside the project.

What this does not change: pack re-prints package.json, sets the executable bits on bin files and adds bundledDependencies files. bun pm diff still shows those three differences between a folder and its own tarball, as 1.4.3 does. The description lists them under Notes.

Self-review raised two changes after the PR opened, both in 00d19c1 (52c0511, 8ab8d69, a7dcd02 and 0ea16f5 address the bot review comments: JSON escapes, path normalization, lockfile precedence): two folders compare as written again (as in 1.4.3), and the lockfile is found from the folder, not from the folder the command runs in. Local runs on the debug build: bun-pm-diff.test.ts (47 pass, 1 skip; the new case fails on 1.4.3), bun-pack.test.ts, bun-publish.test.ts, catalogs.test.ts.

Follow-up to the status above. Self-review after opening found one behaviour change against 1.4.3 that the description does not mention. Reproduced with this branch's debug build (Linux x64).

Two folders, only one inside the invoking project:

mkdir -p /tmp/p/proj/packages/a /tmp/p/proj/packages/b && cd /tmp/p/proj
echo '{"name":"ws-root","private":true,"workspaces":["packages/*"]}' > package.json
printf '{\n  "name": "ws-a",\n  "version": "1.0.0",\n  "dependencies": {\n    "ws-b": "workspace:^"\n  }\n}\n' > packages/a/package.json
echo 'module.exports = 1;' > packages/a/index.js
echo '{"name":"ws-b","version":"1.0.1"}' > packages/b/package.json
bun install
cp -r /tmp/p/proj /tmp/p/clone
diff -r /tmp/p/clone/packages/a ./packages/a      # identical
bun pm diff /tmp/p/clone/packages/a ./packages/a
  • 1.4.3 prints No differences (2 files).
  • This branch prints a package.json hunk (-"ws-b": "workspace:^", +"ws-b": "^1.0.1") and ! dependencies ws-b: workspace:^ → ^1.0.1. With the sides swapped the note is reversed. Piped to a file, the hunk applies with patch -p1 and writes ^1.0.1 over workspace:^.

Cause. project_lockfile covers ./packages/a (a workspace in this project's lockfile) and does not cover the clone, so only one side is rewritten. A git worktree or a second checkout behaves the same way. No test diffs two folders that have workspace: versions.

Two ways to close it. Neither is in this PR yet.

  1. Resolve each folder against its own project root (walk up from the folder to its bun.lock).
  2. Run the rewrite in exec() after both sides are read, and leave a dependency alone when its version is the same text on both sides. A tarball or registry copy still differs as written (^1.0.1 against workspace:^), so the case this PR fixes keeps working.

Also re-ran bun bd test test/cli/install/bun-pm-diff.test.ts on 1df42ad: 47 pass, 1 skip, 0 fail (Linux x64 only; I did not re-run Windows).

I reviewed this and didn't find any bugs. Because the published_version extraction is now shared by bun pm pack/bun publish and the byte-splice path in pm diff is new, a human pass on the pack refactor would still be worthwhile.

What was reviewed:

  • published_version vs. the inlined original in edit_root_package_json — same branch order (^/~/* → lockfile lookup, other workspace: ranges published as-is, catalog: trimmed then looked up), all three error strings preserved verbatim; the dropped expected string value for dependency name crash path now falls through to continue, which is strictly safer.
  • with_published_versions — token replacement is guarded by manifest[at+1..end-1] == *spec so escaped forms stay as written, edits are sorted+deduped so splices can't overlap, and format_json_string_utf8 defaults to quote: true so the replacement re-emits the surrounding quotes.
  • project_lockfile — lockfile load happens before parse_utf8 (per the AST-store reset note), path comparison goes through join_abs_string_buf on both sides, and uses path_buffer_pool::get(); the strings::contains prefilter can false-positive but only costs a lockfile load.
  • Test — extends the existing file, uses the local registry, tempDir/await using/concurrent drain, asserts {stdout, stderr, exitCode} before exit, and covers all four dependency groups plus the negative (vendor/a outside the workspace globs keeps its raw specifiers).
Extended reasoning...

Overview

This PR makes bun pm diff compare a local folder's workspace:/catalog: dependency versions as bun pm pack would publish them. It extracts the resolution logic from edit_root_package_json in pack_command.rs into a shared pub(crate) fn published_version(...) -> Option<Result<Vec<u8>, UnresolvedVersion>> (with an UnresolvedVersion enum carrying the three existing error messages), and has pm_diff_command.rs call it from a new with_published_versions that byte-splices resolved versions into the raw manifest. A new project_lockfile helper loads bun.lock only when the manifest contains workspace:/catalog: and the folder is the cwd package, project root, or a listed workspace. skip_string_token in src/parsers/json.rs is made pub. Docs get one sentence and bun-pm-diff.test.ts gains a test covering ^/~/*/literal-range workspace specs, default and named catalogs, all four dependency groups, and a negative case for a folder outside the workspace globs.

Security risks

None identified. Inputs are the local package.json and bun.lock; there is no network I/O introduced, no path traversal (paths are normalized via join_abs_string_buf and only compared for equality, never opened based on lockfile content), and no shell/command construction. The byte-splice only replaces a token whose raw bytes exactly match the parsed value, so malformed or escape-laden tokens are left untouched rather than mis-spliced.

Level of scrutiny

Moderate. The published_version extraction is now on the bun pm pack / bun publish path, so a behavior drift there would affect what users publish — I diffed the new function against the removed inline code branch-by-branch and the three error strings and all resolution rules are byte-identical (the one dropped path is the Global::crash() on a non-string dependency key, now a continue, which is a strict relaxation). The pm diff side is new logic (lockfile load ordering, path equality across ./packages/a/ vs packages/a, JSON token offset arithmetic) that warrants a human once-over even though I found nothing wrong.

Other factors

The test is thorough and follows repo conventions (existing file, tempDir, local registry, await using, concurrent pipe drain, whole-object .toEqual, stderr/stdout asserted before exit code). The PR description states bun-pack.test.ts, bun-publish.test.ts, and catalogs.test.ts still pass, which is the right coverage for the shared extraction. No CODEOWNERS entries cover the changed paths. The bug hunt ran to dry_streak with no findings. Given ~290 lines including a refactor of code that pack/publish depend on, this doesn't meet the "no human needs to look" bar for auto-approval, hence defer.

With two folders, only the one this project's lockfile covers had its
`workspace:` and `catalog:` versions replaced. Two checkouts of one
package then showed a package.json change that 1.4.3 did not show.

The folder read now records each such version with what pack publishes
for it. `exec` applies them once both sides are read, and skips a
version that the other folder spells the same way. A tarball or a
registry copy spells it differently, so that comparison still uses the
published version.

The gap in the comment above (two folders, only one inside the invoking project) is closed in 9b4a2c5. It uses the second option.

  • Reading a folder now records each workspace: and catalog: version with the version pack publishes for it. It does not edit the manifest at that point.
  • exec applies them after both sides are read. It skips a dependency that the other folder spells the same way in the same section.
  • bun pm diff /tmp/p/clone/packages/a ./packages/a from the repro prints No differences (2 files), in both orders and from inside the clone. This matches 1.4.3.
  • A tarball or a registry copy spells the version differently (^1.0.1 against workspace:^), so that comparison still resolves. bun pm diff pkg.tgz . prints No differences. An extracted tarball against the source folder does too.
  • Two members that spell a dependency differently (workspace:^ against workspace:~) show dependencies ws-b: ^1.0.1 → ~1.0.1.

The new test now also diffs the copy outside the workspaces globs against the member and expects No differences. 71ff501 only shortens the comments that the comment check flagged. The description covers the current state.

Review of the previous commit:

- The same-spelling rule mixed published and written versions in one
  hunk for two folders, so the patch between them no longer applied to
  the files on disk. Two folders now compare as written, as in 1.4.3.
  A folder is converted only against a tarball or a registry version.
- The lockfile was the one of the project the command runs in, so
  `bun pm diff pkg.tgz /abs/path/packages/a` from another folder still
  showed `workspace:^`. The lockfile is now the nearest one at or above
  the folder, when the folder is that project's root or a workspace in
  it. That is the lockfile `bun pm pack` reads in that folder.

00d19c1 replaces the rule from 9b4a2c5. A further review pass found two problems. I reproduced both on the branch build.

  1. The per-dependency rule mixed two spellings in one hunk. With two folders, a dependency that both spell the same way stayed workspace:^, and one that differs became ^2.3.4. bun pm diff ./old/a ./packages/a > changes.patch then no longer reproduced the right folder. Now two folders compare as written, exactly as in 1.4.3. A folder is converted only when the other side is a tarball or a registry version. The clone repro above still prints No differences (2 files).
  2. The lockfile depended on where the command runs. cd /tmp && bun pm diff pkg.tgz /abs/path/packages/a still printed ! dependencies ws-b: ^1.0.1 → workspace:^, because the lockfile was the one of the invoking project. lockfile_for now walks up from the folder to the nearest bun.lock, and uses it when the folder is that project's root or a workspace in it. This also removes the PackageManager argument from read_dir_tree.

One consequence: an extracted tarball against the source folder shows ^1.0.1 → workspace:^ again, as on 1.4.3. Use the tarball itself for that comparison.

The test now runs bun pm diff pkg.tgz ../../packages/a from a folder outside the workspace and expects No differences. The docs sentence and the description are updated. The description also lists what this PR does not cover (pack's re-print, the bin mode bits, bundledDependencies).

Pack resolves what the string decodes to, so `"workspace:\u005e"` is
published as `^1.0.1`. The folder side compared the raw token text and
left such a version as written. It now decodes the token. A manifest
with a backslash in it also loads the lockfile, because an escape can
spell the protocol name.

`join_abs_string_buf` returns its first argument unchanged when there are
no parts, so an absolute path typed with `..` or with mixed separators
never matched a workspace path. The folder now goes through the join as
a part.

…roject's

`lockfile_for` stopped at the nearest lockfile, the folder's own
included. Pack finds the project root first, so a workspace that has a
stray or broken `bun.lock` of its own is still packed with the root's
lockfile. The lookup now takes the first lockfile above the folder when
it lists the folder as a workspace, and the folder's own otherwise.

On the review note about lockfile_for (a lockfile that does not load, "outside diff range" on 8ab8d69): a7dcd02 changes the lookup order.

  • bun pm pack finds the project root first. A workspace is packed with the root's lockfile, even when the workspace folder has a bun.lock of its own.
  • lockfile_for now does the same. It takes the first lockfile above the folder when that lockfile lists the folder as a workspace. Otherwise it takes the folder's own lockfile.
  • A workspace with a stray or broken bun.lock in its own folder therefore still resolves from the project lockfile. The test fixture now has packages/a/bun.lock with invalid content, and every comparison still prints No differences.
  • When the project root's lockfile itself does not load, the versions stay as written and the exit code is 0. bun pm pack fails in that state (failed to parse lockfile), so there is no published form to show. The description says so under Notes.

- Line 771: Update the ancestor lockfile search around the unconditional break
so it exits only when the loaded lockfile reports is_workspace as true; continue

test covering an intermediate ancestor lockfile and a higher ancestor lockfile
that lists the workspace, without relying on the workspace directory’s

Comment thread src/runtime/cli/pm_diff_command.rs Outdated
The walk stopped at the first lockfile above the folder. A lockfile
between a workspace and its project root (someone ran `bun install` in
`packages/`) then hid the root's lockfile, and pack does not look at it.
The walk now continues until a lockfile lists the folder as a workspace.
