Review found three ways the takeover could let two writers overlap.
- A claimant that read an exited PID could remove the lock of a new
holder that reused that PID before the claim. The claimant now probes
the PID again under the claim, after re-reading the record.
- The browser Worker's process shim reports its own PID as absent, so a
second writer in the Worker took over the first one's live lock. A
record naming the contender's own process is never taken over.
- Takeover proves only that the holder exited, while a pnpm run it
started can still be writing the profile. Each profile operation now
records its pnpm run in .plugin-manager/run.json and removes the record
when the run ends; an operation that finds a record waits for the run
within the existing tree bound and otherwise refuses, naming the
process and the record, without running pnpm.
A failed removal of the exited holder's lock now waits instead of
failing the acquisition, the probe range is stated as int32, and the
tests inject exited PIDs instead of reusing real ones, which Windows
reissues at once.
The hostname guarded only writers on several hosts sharing one file,
which no supported deployment does, and macOS changes its hostname when
networks change, so locks from before the change could not be taken
over. The nonce closed a race that needs the PID space to wrap between
two reads. Keeping the `<pid>\n` record lets processes of both releases
interoperate.
A process that ends without running withFileLock's finally left
<file>.lock behind, and every later writer timed out until an operator
deleted it. `dsh plugin` interrupted with Ctrl-C, `dsh web` exiting
right after disposal while a cancelled install still restores files,
and any crash all left the profile package lock this way.
The lock now records its holder's PID, hostname, and a nonce. A
contender that finds a record from this host whose PID a signal probe
reports absent claims that record through a wx-created claim file,
re-reads the lock, removes it only while it still holds the record, and
retries at once. A PID-only record from an earlier release counts as
written on this host, so locks left before this change are taken over
too. Empty, incomplete, foreign-host, and live-holder records are still
waited for.
How long a contender waits is a property of the operation the lock holder
runs, not of the write protocol. The 2s default was sized for the
render-and-rename cycle every call site had; a credential mutation that
refreshes an expired token performs a network round trip while holding the
lock, and leaving the default in place would fail every other writer of that
file for the duration.
`withFileLock` takes an optional `waitMs`; the retry cadence stays fixed
because it governs how often a contender asks, which no caller varies. Every
existing call site keeps the default.
Machine-produced by `pnpm run rescope-vendor --apply` plus the regeneration it
prints: `pnpm install` for the lockfile, `pnpm run gen-third-party-notices`,
`verify-translation-pairing --write` for the touched bilingual pairs,
`gen-doc-graphs`, and one typert snapshot whose ids embed character offsets.
`pnpm run rescope-vendor --check` verifies the result.
Renames nine vendored packages (cordis, cosmokit, schemastery and the six
@cordisjs plugins) and every reference that resolves them: manifest names and
dependency keys, module specifiers including declare-module merges, cordis.yml
plugin names, tsconfig paths, every Markdown fence, and `docs/` prose.
Directory names, upstream versions, and dependency ranges are unchanged, so
vendor/README.md still reads as an upstream snapshot; its manifest table gains
an upstream-name column so THIRD_PARTY_NOTICES keeps MIT attribution pointed
at each fork's origin.
The tutorial tier follows the rename end to end: its yaml fences named plugins
the Loader can no longer resolve, its `ts ignore-check` fences disagreed with
the compiled fences beside them, and its prose quoted both. The contracts that
told readers to keep upstream names — the root convention and the vendoring
cookbook's tree comment and manifest invariant — now say to rescope instead.
Two rules read `@deepseek-ai/` as "another workspace plugin": the client bundle
purity gate now names the vendored libraries a browser bundle inlines, and the
files where a bare `cordis` is an agent-preset id keep that product data.
writeFileAtomic: exclusive-create random-suffix temp + rename carrying the
caller-stated mode; settings-local persistSection now consumes it. The
credentials-local store shares it next.
