* fix(watcher): keep macOS FSEvents paths under the subscribed worktree root
macOS FSEvents reports OS-canonical paths: symlinks resolved and every
directory in its on-disk spelling. Linux (inotify) and Windows both rebuild
event paths from the directory that was subscribed, so only macOS observes
the mismatch.
Orca's watcher contract is "event paths live under worktreePath". Consumers
derive a worktree-relative path with relativePathInsideRoot(), which returns
null when the event falls outside the root -- and a null relative path drops
the event silently. So on a Mac whose worktree or folder path traverses a
symlink (~/code -> /Volumes/..., anything under /tmp or /var), or is spelled
with different casing than disk on a case-insensitive volume, every watcher
event was discarded: the editor never reloaded an agent's edit, the File
Explorer never refreshed, and Source Control never re-ran status. Nothing
errored, which is why this looked like "the file watcher stopped working"
on some machines and not others.
Rewrite event paths back onto the subscribed root inside
subscribeThroughWatcherSupervisor -- the single boundary every desktop,
runtime-environment, and SSH-relay watch passes through -- so one change
covers all three transports.
The resolution runs alongside the subscribe rather than before it: an await
ahead of the subscribe call lets a caller's abort land in a window where no
watcher-process subscription exists to cancel, which hangs the existing
cancellation contracts. The subscribe promise settles only after the rewrite
is installed, and only after the subscription itself is recorded, so
teardown never waits on a realpath.
Matching folds per path segment (NFC + case) instead of by prefix length,
because both folds change length and a folded-prefix length would slice the
raw event path mid-character. Byte-exact fast paths run first, so unaliased
roots -- every Linux and Windows watch, and most macOS ones -- cost one
string comparison per event and allocate nothing.
* fix(watcher): watch the resolved root so symlinked worktrees work on Linux too
Verified on a real Linux host: @parcel/watcher passes IN_DONT_FOLLOW |
IN_ONLYDIR to inotify_add_watch, so a symlinked worktree root fails outright
with ENOTDIR ('Not a directory'). The watch never installs and Orca caches the
root in unwatchableRoots, so it is never retried for that session. That is a
worse symptom than the macOS path-spelling mismatch and hits Linux users of
symlinked checkouts on every machine.
Hand the backend the resolved directory instead of the caller's spelling, and
keep mapping delivered paths back. Resolving the root also lets
@parcel/watcher's own ignore paths match again on macOS, where they were
computed from the unresolved root and silently excluded nothing.
The resolve is synchronous on purpose. Every caller reserves and forks its
watcher child in the same tick as the subscribe call -- capacity accounting and
cancellation ordering both depend on it, and 30+ existing tests encode it -- so
an await here would open a window where a subscribe is issued but no
cancellable child exists.
* test(watcher): use a directory junction on Windows so the alias repro runs there
Creating a directory symlink on Windows needs elevation or Developer Mode, so
the alias tests failed with EPERM on a real Windows host. A junction needs
neither, is what users actually have (a junctioned C:\dev), and realpath
resolves it identically -- so one fixture now covers all three platforms and the
end-to-end repro no longer skips outside Linux and macOS.
* test(watcher): pin the fabricated-path failure modes of the root rewrite
A rewrite that returns a WRONG path is worse than no fix -- a consumer would
act on the wrong file -- so pin the cases that could produce one: sibling
directories that share a prefix with the root (POSIX and UNC), the root itself
versus a shorter path, drive-letter casing, a root-only canonical path, and a
script where toLowerCase changes length. Found by running the rewrite over an
adversarial table; all already passed, so these lock in behaviour rather than
fix it.
* docs(watcher): drop an unverified claim about ignore paths
I claimed resolving the root also repairs @parcel/watcher's ignore-path
matching for aliased roots. Probing it on macOS shows the node_modules write is
excluded either way: FSEvents resolves symlinks in its own exclusion paths, so
the daemon filters at the source regardless of which spelling we subscribe with.
On Linux the exclusions are userspace globs relative to the watched directory
and there was no watch at all before this change, so there is nothing to
compare. Removing the claim rather than leaving a plausible-but-wrong rationale
in the module header.
* refactor(watcher): simplify root path rewriter
* test(palette): build searchable fixture documents
