install: keep an optional git, GitHub or tarball dependency on its locked package while it is read again by robobun · Pull Request #46276 · oven-sh/bun

Problem

bun update removes a locked optional git, GitHub or tarball dependency from bun.lock when it cannot read the source. It exits 0 with only warn: GET <url> - 503, and a frozen install passes.
The differ unbinds the dependency before the read (src/install/lockfile/Package.rs:1221). A failed optional read is only a warning, so clean_lockfile drops the package.

Fix

The dependency keeps its package during the read. Scratch::refreshing, one bit per dependency, marks it as not yet resolved.
enqueue::refreshes_in_place picks the dependencies. bun update prints warn: <name>@<resolution> was not checked for updates per kept package.
enqueue_tarball_for_reading fails fast for a read that already failed, as enqueue_download does. The isolated linker waited forever there (main too, with --force).
Verified: test/cli/install/bun-install-retry.test.ts (72 new cases, 34 fail on main), and all 100 suites of test/cli/install. Self-reviewed: 19 concerns raised, 17 addressed.

Background

A dependency has a slot with the id of its package. clean_lockfile removes each package that no slot holds.
Considered: put the package back in each failure arm. Every exit needs that edit.
Open for a maintainer: keep at exit 0, or fail. npm 11 and pnpm 12 drop the entry. install: keep an optional registry dependency on its locked version while its manifest is read again #45966 asks the same.

Downsides

bun update --frozen-lockfile now exits 0 here (main: 1, the lockfile changed).
On an empty cache, a failed download below the kept package makes bun update exit 1 (main: 0).
Cost: .text +7,936 bytes and 3 instructions per assign_resolution call.

Notes

Cells. One locked optional dependency in the root package.json. Its source then answers 503, or the repository or the file is gone.

Cell	1.4.3 (`c6da4a4`)	main	this PR
tarball URL, `bun update`	exit 0, dropped	exit 0, dropped	exit 0, kept
GitHub, `bun update`	exit 0, dropped	exit 0, dropped	exit 0, kept
git, `bun update`	exit 1, kept	exit 0, dropped	exit 0, kept
`file:` tarball, `bun update`	exit 1, kept	exit 0, dropped	exit 0, kept
tarball URL, `bun install --force`	not read, kept	exit 0, dropped	exit 0, kept
`file:` tarball, `bun install --force`	not read, kept	exit 0, dropped	exit 0, kept

"Dropped" means that the package leaves bun.lock and node_modules. After that, bun install --frozen-lockfile exits 0 without it, and a plain bun install does not bring it back. The git and file: tarball rows are new on main (#44968, #45307). Main has the same loss for a dependency of a workspace, for an optional dependency of a git or GitHub package, with --latest, with --lockfile-only, and for GitHub with --offline. In a matrix of 87 such cells, main drops the package at exit 0 in 52. This PR does so in 8, which are the controls where the entry asks for another source. No exit code differs in that matrix.

Decisions for a maintainer.

Keep and warn at exit 0, or fail the command? install: consolidate the open package manager pull requests #44968 made these failures warnings. npm 11 and pnpm 12 exit 0 and drop the entry. This PR keeps the package, because a frozen install of Bun accepts the smaller lockfile and no later install restores the entry. install: keep an optional registry dependency on its locked version while its manifest is read again #45966 lists the same choice for registry ranges.
Scratch::refreshing is a new state of a dependency: it has a package, and the resolver still has to resolve it. Scratch::unplaced_subtree is the nearest precedent. assign_resolution clears the bit on every bind. Two other shapes are possible. Without the bit, the places that replace dependencies keep the slot, and the two gates that read the slot also pass under bun update. The self-review put that variant at 40 to 50 lines for the cells in the table. It is not built. If the answer to 1 is "fail", one check before clean_lockfile is enough, and no state is needed.

What decides that a dependency keeps its package. enqueue::refreshes_in_place needs all of these:

The dependency is optional, and it is a git, GitHub or tarball dependency.
bun.lock has a dependency of the same package with the same name, group and specifier.
The package in the slot comes from the source that the specifier names: the same owner and repository, repository URL, URL or path. A bun.lock from 1.4.3 or older binds a dependency that never resolved to any package of its name. bun.lock has the commit and not the ref, so the ref is not compared.
No overrides rule exists for the key or for the name of the package, in bun.lock or in package.json. A rule for the name that the source has after the read also ends the keep: bind_row then resolves the dependency as main does.
The resolver would not refuse the dependency: the key is a safe folder name, and a file: tarball is named by a package.json of the project. The resolver and the predicate call the same two functions for this.

The four places that start such a read call it: the root after the differ, Diff::keep_resolutions for a workspace that is read again, append_extracted_package for the dependencies of a git, GitHub or tarball package that is read again, and enqueue_named_updates.

The linker change. A read of a file: tarball that failed while dependencies were resolved leaves no task. enqueue_download already answers AlreadyFailed for a download in that state. enqueue_tarball_for_reading did not, and put the linker on a list that nothing serves. With the isolated linker, an empty cache and no node_modules, the command then never ends. On main that happens for bun install --force when the root and a workspace have the same optional file: tarball, the file is gone, and the workspace gets its turn after a new registry dependency. A kept package makes more commands reach that state, so the fix is part of this PR.

Still dropped, as on main.

A dependency that bun.lock has no package for.
A dependency with an overrides rule, and one that is catalog:.
An optional dependency of a git or GitHub package whose ref moved in the same bun update, and of an npm package that moved to another version. The dependencies are paired only when the package is the same.
An optional file: tarball that a file: folder of the project declares.
A git dependency whose ref no longer exists while the repository does. That is an answer, not a failed read. With --offline the cached clone gives that answer.
A bun.lock from 1.4.3 that records a gitlab: or bitbucket: shorthand, until a bun update with a readable source writes it again.
file: folders and link: dependencies. The linkers fail on a missing folder, so a kept package turns exit 0 into exit 1. That needs a change in the linkers first.
Registry ranges: install: keep an optional registry dependency on its locked version while its manifest is read again #45966.

Other changes in behaviour.

An empty cache and no node_modules: the linker has to install what bun.lock keeps, as bun install does with the same lockfile. A required dependency of the kept package that cannot be downloaded is an error there. So is an answer that is not the archive that bun.lock pins (integrity). A request that names the package by its name, when the key of the entry is another, fails too. Main exits 0 in these cases, because it dropped the packages. bun add and bun remove with --force reach the same rule when only the cache is empty.
In that state the kept package is asked for once more by its commit, and the failure is printed once more. A later bun install asks again, and installs the package when the source is back.
bun update --no-save no longer removes the installed package of a GitHub or git dependency that it could not read.
A workspace has a peer dependency on the name of the optional dependency: main asks the registry for that name, and exits 1 or installs the registry package. This PR keeps the package and asks nothing.
bun update <name> where <name> is the name of the package and the entry has another key: main exits 0 and drops the package. This PR exits 0 and keeps it. A pattern behaves like that name unless the key of the entry is also the name of the package.
A command that selects the dependency by its key, with --production or with --depth 0 exits 1 and saves nothing, as on main. A command that has failed before the lockfile is cleaned does not print the new line.
With the isolated linker, --force and an empty cache, the installed copy of the kept package is removed and cannot be installed again until the source is back. That is what --force does for a git or GitHub package on main.
--silent prints nothing, as on main. --offline prints only the new line for a GitHub dependency.

Related PRs.

install: keep an optional registry dependency on its locked version while its manifest is read again #45966 keeps the locked version of an optional registry range. If this state is accepted, it can rebase on it: a dependency that is declared as in bun.lock stays bound, and its lookup by name and range is only needed for a dependency that starts without a package. Both PRs print the same line.
install: key overrides by the name a dependency is declared under #45750 changes the key of the overrides lookup and edits the same bind sites in bind_row_without_manifest and assign_resolution. The second one to land has a small rebase. refreshes_in_place only asks whether a rule exists for a name, so it does not depend on that key.
install: retry an optional dependency that an earlier install left unresolved #45942 retries an optional dependency that an earlier install left without a package. That is the other way into the same state of bun.lock.

Not in scope. A bare bun update in a workspace directory, or with --filter, also reads the sources of dependencies outside that scope. The new cases show it: the package is kept there too. The missing scope check is a separate change.

Tests. 72 new cases in test/cli/install/bun-install-retry.test.ts. 34 fail on a build of main's src/install, one of them by the 5 minute timeout of the file (the --force hang). The other 38 are controls that pass on both: a healthy source, a required dependency, a changed entry, a selected entry, an entry with an overrides rule, a ref that is gone, a tarball URL that is not read again, and two bun.lock files in the format of 1.4.3.

The gates in the resolver were reverted on a debug build of an earlier revision. Without the look-ahead gate, 2 cases fail. Without the filter in fail_update_requests, 1 case fails. needs_ctx, the gate for a package that is already appended and the unbind for a git ref that is gone were reverted together: 12 cases fail.

All 100 suites of test/cli/install ran on a release build of this PR: 12,187 tests pass. semver.test.ts cannot load the semver package in this container, on main too. Eight suites needed --timeout 120000, because this container is slow: bun-install-git-deps, bun-install-registry, bun-install-security-provider, bun-pack, bun-pm-diff, bun-publish and the two bun-security-scanner-matrix suites. With the default 5 s, a varying set of their tests times out here. Main's build shows the same timeouts in the five of these suites that were compared.

Measurements. Release builds of main's src/install and of this PR, on the same base (ea6a2c7).

Size (size -A): .text +7,936 bytes, .rodata, .data and .bss +0.
assign_resolution (objdump -d): 106 instructions on main, 128 here. A call runs 3 more while no dependency is refreshed: one load, one compare, one branch.
User instructions (perf_event_open, 15 interleaved runs, median): a no-change bun install of 220 packages takes 12,956,850 on main and 12,957,417 here (standard deviation 66,588 and 64,479). A fresh bun install --lockfile-only takes 15,779,626 and 15,774,816 (standard deviation 5,378 and 8,632).
A healthy bare bun update in a workspace of 200 members (12 interleaved runs, median): 33,571,190 on main and 33,637,975 here, +0.20%. Two runs of main's build differ by 113,021. With one optional tarball URL in each member, which makes 200 dependencies that are refreshed: 39,511,450 and 39,686,343, +0.44%.
A healthy refresh sends the same requests in the same order, starts the same git processes, prints the same lines and writes the same bun.lock on both builds, in 66 of 66 fixtures (3 declarers, 4 kinds, a changed and an unchanged source, bun update, --latest, install --force). A wider comparison of about 18,000 healthy fixtures on an earlier revision found no difference that either build reproduces.
20 failing runs with a random delay per route give one bun.lock here, equal to the one before.
Allocation counts are not measured: valgrind, perf and strace are not in this container. By the code, the bitset allocates at the first dependency that is marked in a run, and DiffSummary::overridden_names is a copy of a list that is empty unless overrides changed.

Self-review. Two passes. The first found these, and all are addressed: the mark did not look at the package in the slot, the predicate copied the rule lookup of the resolver, a dependency that the resolver refuses kept its package, a kept dependency changed which request a failed download fails, the root and a workspace paired dependencies by different rules, a git ref that is gone was treated as a failed read, the list of changes in behaviour was incomplete, the cases did not pin each gate, file: folders and link: were fixed in the wrong layer (now out of this PR), a name clashed with the meaning of "unresolved" in bun.lock, the list of what is still dropped was incomplete, and the reason for the new state was overstated.

The second found seven more. Five are addressed: the linker waited for a failed file: tarball read, a rule for the name that the source has now left the dependency on the old package, the git fixture used the signing config of the machine, no case covered the overrides conditions, and the docs bullet claimed more than the command does. Two are not changed: the two exit codes on an empty cache in the list above. They are the rules that bun install applies to the same lockfile.

…cked package while it is read again `bun update` reads the source of a git, GitHub or tarball dependency again, and `bun install --force` does so for a tarball. The dependency had no package during that read. A failed read of an optional dependency is a warning, so the package left bun.lock and node_modules at exit 0, and a later `bun install --frozen-lockfile` passed without it. The dependency now keeps the package that bun.lock has for it. A bit per dependency, `Scratch::refreshing`, tells the resolver that it still has to resolve the dependency, and `assign_resolution` clears it. `enqueue::refreshes_in_place` decides which dependencies qualify, at the four places that start such a read: the root after the differ, a workspace that is read again, the dependencies of a git, GitHub or tarball package that is read again, and a named update. A dependency qualifies if it is optional, if bun.lock has the same entry with a package from the source that the entry names, if no `overrides` rule exists for its key or for the name of that package, and if the resolver would not refuse it. A rule for the name that the source has after the read ends the keep. A git ref that the repository no longer has is an answer, and the package leaves as before. `bun update` prints `warn: <name>@<resolution> was not checked for updates` for each package that was kept. `enqueue_tarball_for_reading` now answers `AlreadyFailed` for a `file:` tarball whose read has failed, as `enqueue_download` does for a download. The isolated linker waited for such a read forever. On main that happens with `bun install --force` and an empty cache when the root and a workspace have the same optional `file:` tarball and the file is gone.

Status

Reproduction: a loopback server serves one locked optional dependency (a tarball URL, a GitHub repository, a git repository or a file: tarball). During a bare bun update it answers 503, or the repository or the file is gone. On main (9b4284f) the command exits 0 and removes the package from bun.lock and node_modules. A later bun install --frozen-lockfile exits 0 without it. The new cases in test/cli/install/bun-install-retry.test.ts run this for each kind, in the root, in a workspace and below a GitHub package.

Walkthrough

The update flow now retains eligible locked optional Git, GitHub, and tarball dependencies while attempting source refreshes. It handles refresh failures and reports sources that were not checked. CLI tests and update documentation cover the behavior.

Changes

Optional dependency source refresh

Layer / File(s)	Summary
Refresh eligibility and lockfile state `src/install/lockfile/Package.rs`, `src/install/lockfile.rs`, `src/install/PackageManager/PackageManagerEnqueue.rs`	The lockfile tracks dependencies undergoing refresh. In-place refresh eligibility checks dependency type, source matching, local-tarball rules, overrides, and aliases.
Refresh execution and failure handling `src/install/PackageManager/install_with_manager.rs`, `src/install/PackageManager/processDependencyList.rs`, `src/install/PackageManager/PackageManagerResolution.rs`, `src/install/PackageManager/PackageManagerEnqueue.rs`, `src/install/PackageManager/runTasks.rs`, `src/install/PackageManager/PopulatePackageCache.rs`, `src/install/PackageInstaller.rs`, `src/install/isolated_install.rs`	Named updates preserve eligible rows while refreshing. Enqueue paths propagate failed-task results, and resolution and task-failure handling update refresh state.
Unchecked-source reporting and coverage `src/install/update_transitive.rs`, `src/install/PackageManager/install_with_manager.rs`, `test/cli/install/bun-install-retry.test.ts`, `docs/pm/cli/update.mdx`	Updates warn when eligible locked packages are kept without refreshing their sources. CLI tests cover source failures and update behavior; the documentation describes the fallback and failure conditions.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 2b01c

The change preserves locked optional git, GitHub, and tarball dependencies when their sources are unreadable during updates. One narrow case misbehaves: an optional peer dependency with such a source can cause bun update to print a misleading "was not checked for updates" warning and keep its old binding. The fix is a one-line exclusion and should be applied before merge.

The one review finding (an optional peer dependency is kept in place and gets the new warning) does not apply, so there is no change for it.

may_refresh_in_place tests Behavior::is_optional(), which is false for an optional peer (src/install_types/resolver_hooks.rs:210-212). A run on a release build of this branch agrees: an optional peer with a GitHub specifier gets no package and no warning under bun update, as on main. The details are in the resolved thread: #46276 (comment)

claude

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

Beyond the inline findings, I also checked the refactors in this diff for behavior drift: the may_name_local_tarball extraction in PackageManagerEnqueue.rs is equivalent to the inlined condition it replaces (the parent lookup is already required on both sides), the keep_resolutions reorder in lockfile/Package.rs leaves the non-to_update path unchanged, and all three callers of enqueue_tarball_for_reading now propagate its Result. The new Scratch::refreshing bitset is never reset, which matches the existing unplaced_subtree precedent.

Extended reasoning...

The change adds a per-dependency "refreshing" state to the Bun package manager's lockfile scratch so that optional git, GitHub and tarball dependencies keep their locked package while the source is re-read during bun update, touching the differ, enqueue, resolution and task-failure paths across 12 source files plus a large test addition. It touches no auth, crypto or injection surface, though it changes which packages survive clean_lockfile. Three verified findings are posted inline, and the change is a non-trivial state-machine addition to a core resolver path, so a human maintainer should also review it; this body only records the additional refactor checks that were examined and ruled out.

Additional findings (outside the current diff — GitHub can't attach inline comments there):

🟣 src/install/PackageManager/PackageManagerEnqueue.rs — Users running bun update with an optional git dependency whose clone fails now see the clone attempted twice and the failure printed twice for a row the PR deliberately keeps. The look-ahead at PackageManagerEnqueue.rs:1360 now runs for refreshing rows (awaits_resolve is true), its clone fails, forget_failed_git_task at runTasks.rs:1418 drops the dedupe entry, and has_created_network_task at PackageManagerEnqueue.rs:2357 then starts a second clone at the row's turn. Fix: keep the failed clone recorded (do not forget the network_dedupe_map entry, or check network_task_has_failed before enqueue_git_clone) so every refreshing or unbound git row is cloned once and warned once.

Why this was flagged

Trigger: bun update on a project whose root package.json has an optional git+https://... dependency locked in bun.lock, and the host answers an error or is unreachable. The differ keeps the row via keep_while_refreshing (lockfile/Package.rs:1774) and enqueues it. request_remote_package_ahead at PackageManagerEnqueue.rs:1360 no longer returns early because awaits_resolve(id) is true for a refreshing row, so a clone task starts. On failure runTasks.rs:1418 calls forget_failed_git_task, which removes the dedupe entry. When advance() reaches the row, bind_row_without_manifest at PackageManagerEnqueue.rs:2357 sees no created task and enqueues a second clone (2364), which fails again and prints the warning again. The PR adds a new population (kept rows under update and --force). The remedy is to record the failed clone instead of forgetting it, so a second attempt is refused like a failed tarball download is by has_already_failed (PackageManagerEnqueue.rs:478).

Verification: pre-existing: the double clone and doubled "cloning repository for" warning are real, but the base branch does the same thing by the same route for the same rows; this PR does not introduce or widen it. The old gate resolution != invalid_package_id at PackageManagerEnqueue.rs:1360 also let the look-ahead run, and forget_failed_git_task at runTasks.rs:1418 is unchanged from base.

        version_was_replaced,
    } = asked;
+    // A rule for the name that its source has now replaces what the dependency asks for.
+    let resolution = if version_was_replaced && this.lockfile.is_refreshing(id) {


🟡 (optional) A refreshing row whose replaced version carries an unsafe install name stays bound to its locked package with the refreshing bit set, so bun update keeps the stale package and prints was not checked for updates for it, where the base dropped the row. unsafe_name at PackageManagerEnqueue.rs:1975 returns Row::Done before the version_was_replaced unbind at PackageManagerEnqueue.rs:1992 runs. Fix: move the unbind_refreshing for version_was_replaced ahead of the unsafe_name check, so every early exit of bind_row that abandons a replaced row also drops the kept package.

Why this was flagged

A row marked refreshing by keep_while_refreshing or enqueue_named_updates reaches bind_row. asked_version (src/install/PackageManager/PackageManagerEnqueue.rs:1841) applies an override rule keyed by the realname hash, which for a lockfile-loaded row whose package_name is filled can differ from both dependency.name_hash and the locked package's name hash that refreshes_in_place checks at PackageManagerEnqueue.rs:1147-1148. If the rule's target has a name that alias_is_safe_install_target rejects, unsafe_name returns it and bind_row exits at PackageManagerEnqueue.rs:1982 with Row::Done, before the unbind at PackageManagerEnqueue.rs:1992-1994. The row keeps the locked package and its refreshing bit; nothing else clears it, so kept_without_refresh (lockfile.rs:2574) lists the package and warn_unchecked_sources prints a misleading was not checked for updates line. On the base branch the row was invalid and clean_lockfile dropped the package.

Verification: When that rule's target is unsafe, unsafe_name (src/install/PackageManager/PackageManagerEnqueue.rs:1915-1923) returns Some, and line 1975-1982 returns Row::Done BEFORE line 1992-1994. The row therefore stays bound to the locked package with refreshing set. On the base the row was unbound to invalid_package_id before the read, so the same Row::Done dropped the package via clean_lockfile.

+                    }


🟣 pre-existing, not blocking: pre-existing: a user running bun update --offline with a stale cached clone still loses an optional git dependency from bun.lock at exit 0. The GitCommit failure arm at runTasks.rs:1567-1571 calls unbind_refreshing for every waiter, treating "no commit matching" as an authoritative answer. Under --offline the bare clone is reused without a fetch (git_runner.rs:938-945), so a ref added upstream after the clone is simply absent locally, not gone. Fix: keep the locked package (skip unbind_refreshing) when options.offline == OfflineMode::Offline, so an unfetched clone's miss is treated like an unreadable source rather than a confirmed removal.
A small fix can ride a push you are already making; otherwise a short reply is enough.

Why this was flagged

A project has an optional git dependency foo: git+https://host/foo.git#v2 locked in bun.lock, and the user's cache holds a bare clone of foo.git made before tag v2 existed. The user runs bun update --offline. The differ unbinds the row, keep_while_refreshing rebinds it as refreshing, bind_row_without_manifest enqueues the clone, and begin_clone (git_runner.rs:927-945) returns the cached repo without fetching because offline is set. The row re-enters, finds no git_commits entry, and enqueues a GitCommit task that fails because the stale clone has no v2. The GitCommit fail arm at runTasks.rs:1567-1571 calls unbind_refreshing for the Dependency waiter, so the row goes back to invalid_package_id, only a warning is logged, and clean_lockfile drops the package: bun.lock and node_modules lose foo at exit 0. The base branch drops it the same way, so this is a path the fix leaves failing; the PR description calls the offline miss "an answer", but the clone was never fetched, so it is not one.

Verification: pre-existing; acknowledged in diff. Trigger: bun update --offline with an optional git dependency locked in bun.lock to a ref that the cached bare clone predates. git_runner.rs:927-944 reuses the cached clone and skips fetch_next when offline; the GitCommit fail arm at runTasks.rs:1566-1571 calls manager.lockfile.unbind_refreshing(id), so the optional dep is dropped at exit 0. The base branch fails by the same route.

… pack and bun: imports (oven-sh#46455) ### What does this PR do? Brings 7 open pull requests together on current `main`. Each fixes something that `main` does and Bun 1.4.3 does not. Nothing is rewritten: each is the squashed diff of that pull request's head, and each description lists its own downsides. | PR | What it changes | |---|---| | oven-sh#46372 | install: read the value of an alias-keyed override under the alias name | | oven-sh#46367 | install: rebind cached package ids before the second resolve pass | | oven-sh#46276 | install: keep an optional git, GitHub or tarball dependency on its locked package while it is read again | | oven-sh#46406 | bun patch: keep the checkout that `bun link` linked into node_modules | | oven-sh#45697 | install: make a bin that loses its .bin name executable. bunx: stop when the project's copy cannot run | | oven-sh#46361 | pack: apply the ignore files of a bundled linked folder whose package.json does not load | | oven-sh#44878 | Keep the `bun:` prefix of an import that names no builtin, in bundles and at run time | The later commits add and then take out pull requests for faults that 1.4.3 has too. The tree is the same as after the seventh commit. ### Conflicts | File | Between | Resolution | |---|---|---| | `src/install/PackageManager/install_with_manager.rs` | oven-sh#46276 and oven-sh#46367 | both add a name to one `use` list. Both are kept | | `src/jsc/RuntimeTranspilerCache.rs` | oven-sh#44878 and `main` | `main` is at cache version 42, so this change is version 43 | ### Behavior changes | PR | Before | After | |---|---|---| | oven-sh#45697 | `bunx <pkg>` runs the registry's copy when the project's own bin file is missing or not executable | it stops: exit 126, or exit 1 | | oven-sh#46372 | `"my-alias@npm:pkg@^1": "catalog:"` reads the catalog entry of `pkg` | it reads the entry of `my-alias`. The same for `workspace:*` | | oven-sh#44878 | an unknown `bun:name` is looked up as `name` | it stays `bun:name` | ### How did you verify your code works? - Not built locally. CI is the first build of the combination. - Every test of the 7 pull requests comes along. - Four files are touched by two of them. Outside the `use` list above, their hunks are in different functions, or far apart in `install_with_manager()`. - No conflict markers are left, and Prettier passes on every changed file. Closes oven-sh#46372 Closes oven-sh#46367 Closes oven-sh#46276 Closes oven-sh#46406 Closes oven-sh#45697 Closes oven-sh#46361 Closes oven-sh#44878 --------- Co-authored-by: robobun <117481402+robobun@users.noreply.github.com>

The earlier commits of this branch gave an optional registry dependency a package again at the end of `bind_row`, with a record of kept rows on the manager. main now keeps an optional git, GitHub or tarball dependency on its locked package while its source is read again (#46276). The registry case is built on that mechanism in the commits that follow, so this merge takes the tree of main as it is.
