Conversation
The install phase parks a waiter on the clone of a git repository that is not in the cache. The waiter was a dependency, and when the clone ended the checkout was derived from it: the hoisted linker read the package the dependency resolves to, the isolated linker sent the dependency through the resolver again. The isolated linker keeps one dependency per store entry, and that one can be a peer dependency, or a dependency that an override redirects. Neither is a git dependency, and a peer dependency can resolve to another package. No checkout started for the entry and the install never exited. The waiter is now TaskCallbackContext::GitCheckout with the package id. Both linkers start, or fail, the checkout of that package when the clone ends.
enqueue_git_checkout looked up the package to patch by the name of the dependency. An alias does not share its name with the package, so the lookup found nothing: panic: Package not found. When two packages share a name, it took the first one. enqueue_git_for_checkout now passes the package id with the patch hash.
It existed for the isolated linker, which sent a resolved dependency through the resolver again when a clone ended. The linker no longer does that, and no resolve-phase caller reaches the arm with a resolved git dependency.
…om the dependency The isolated linker cloned the repository a second time, under the dependency's spelling, and left the package waiting. The typed clone waiter starts the checkout of the package in bun.lock.

… adds another package of its repository A plain bun install hits the same panic as bun add: the resolve phase clones the repository for the new dependency, and the patched package then takes the checkout that applies the patch.

The override test said the dependency was no git dependency. The install hung because the resolver found the package of the pinned commit already loaded. Also guard the URL spelling test against a replace that matches nothing.

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.
Beyond the inline nit, I also checked the removal of the pinned branch in the resolver's git arm (the re-entry after git log reads the same SHA from git_commits, so the checkout id is unchanged), the clone-failure drain in run_tasks (every GitCheckout waiter now gets on_package_download_error_store with its own package's checkout id, replacing the single clone.res fallback), and the .git() reads on items_resolution()[package_id] without a tag check (both call sites only push GitCheckout waiters from enqueue_git_for_checkout, which is reached only for git resolutions). Since the change rewires the clone-waiter and patch-lookup flow for both linkers, a human familiar with the install task queue should still take a look.
Extended reasoning...
The change replaces the dependency-keyed waiter on shared git clone tasks with a typed GitCheckout { dependency_id, package_id } variant across the hoisted and isolated install paths in the bun_install crate, removes the GitCloneRequest.res fallback, and moves the patch target lookup from a name-hash index to an explicit package id; it touches no auth, crypto, or input-parsing surface. The core waiter flows and the dropped-tag-check union reads were traced and look consistent, but the change alters hang/failure semantics in the install loop for both linkers, so a human look is still worthwhile.
Each case runs two installs and takes under a second on a debug build. The explicit 30 s also lowered the limit that the CI runner sets.

- Around line 1391-1420: Update the Git dependency resolution path in the branch
using `this.git_commits.get(&commit_id)` to prefer the stored resolved SHA from
the lockfile when the dependency already has a Git resolution and no context is
needed. Fall back to `git_commits` and enqueue `GitCommit` only when no stored
SHA is available, so checkout uses the pinned commit rather than a moved branch
target.

Thanks for dropping the per-test timeouts in e1a7d18 — that resolves my earlier nit. I re-reviewed the updated branch and found no bugs, but since this reworks the install-phase clone-waiter machinery and deletes two fallbacks (the clone-failure drain's clone.res path and the resolver's pinned branch), a maintainer familiar with src/install should still take a look.
What was reviewed:
- The
GitCheckoutwaiter end to end: pushed inenqueue_git_for_checkout(PackageManagerEnqueue.rs:329), consumed in bothrunTasks.rsclone arms; the checkout-id entry still carries the original install context, so the post-clone checkout completes the same entry it did before. - The
has_on_extractgate relaxation: onlyHoistedRunTasksCallbacksandStoreRunTasksCallbackssetHAS_ON_EXTRACT = true, so the resolve phase still goes throughprocess_dependency_list, and the newdebug_assertthere covers a mis-routedGitCheckoutwaiter. - Patch
Nonein the post-clone checkout path (runTasks.rs:1427) — pre-existing, not a regression from the signature change. - Other
TaskCallbackContextmatch sites (Installer.rs,PackageInstaller.rs,auto_installer.rs) uselet ... else/ single-variant matches and are unaffected by the new variant.
Extended reasoning...
The change touches the install-phase git clone/checkout task plumbing in src/install (lib.rs enum, PackageManagerEnqueue.rs, runTasks.rs, processDependencyList.rs, the two linkers' call sites) and adds eight tests to test/cli/install/bun-install-git-deps.test.ts; it touches no auth, crypto, or input-validation surface beyond lockfile-driven package ids. The bug hunt ran dry with no findings and the single commit since the prior review removed the per-test timeouts that review flagged. Deferring rather than approving because the change deletes a fallback in the clone-failure arm and the resolver's pinned-commit branch, both of which are behavior the author justifies by measurement rather than by a compile-time invariant, and the install task queue is core, maintainer-owned logic.

Problem
bun installnever exits when a git dependency is the peer of a package that sorts before it. A gitoverridesentry or a differently spelledbun.lockURL does the same.PackageManagerEnqueue.rs:328). When the clone ended, the isolated linker resolved it again (runTasks.rs:1465). For a's peerb: "*"no checkout started.panic: Package not found.Fix
TaskCallbackContext::GitCheckout { dependency_id, package_id }. Both linkers start that package's checkout when the clone ends. The isolated linker fails each waiter when the clone fails.enqueue_git_checkoutgets the package to patch from its caller. Removed:pinnedin the resolver's git arm,GitCloneRequest.res, the clone-failure fallback.test/cli/install/bun-install-git-deps.test.ts, 8 new tests. Without the fix 6 time out and 2 panic.Background

Notes
Repro (offline, from the report): a workspace member depends on
b=git+file://.../b.git#mainand on registry packagea@1.0.0withpeerDependencies: { "b": "*" }. The namebis on the registry too. Runbun install, removenode_modulesand the cache, and runbun installagain. The second install exits 124 undertimeout 10on main4b02e1031d. It exits 0 with--linker hoistedor whenais namedz. bun.lock resolves a's peer to the registryb(a/b), and the isolated store linksato the workspace's gitb.Why the hoisted branch is not enough. It starts the checkout of
resolutions[dep_id]. For the store entry of the gitb,dep_idis a's peer dependency, andresolutions[dep_id]is the registryb. An optional peer has no resolution at all.The panic. A patch is applied right after the checkout when the repository was cloned earlier in the same process. The package to patch was looked up by the name of the dependency. Repro: a patched git dependency under an alias, bun.lock, an empty cache, and a second package of the same repository that the install must resolve first. The second package can come from
bun add <url>or from an edit of package.json followed by a plainbun install. Both exit 134 without the fix and exit 0 here with the patch applied. Without the alias, without the patch, or with no new package to resolve, the install exits 0 before and after.bun addwas checked by script with both linkers.
