- applyWorkspaceHooks: an "unknown" probe that is not near a stalled path
(refused by the stall cap, or an unexpected stat error) no longer reads as
"go ahead". It checks existence with pathExistsForWrite first, so a deleted
workspace is not recreated by the mkdir -p in ensureCodemanHooks.
- pastCap gets a hard ceiling, PATH_PROBE_STALL_CEILING = UV_THREADPOOL_SIZE
(default 4) minus one, so explicit requests against several dead paths can
never take the last libuv worker. The bulk cap now defaults to one below the
ceiling (2 with the default pool), leaving a slot for an explicit request.
- A stall widens to its mount only for network and FUSE filesystem types read
from /proc/self/mounts; on a local mount (a path typed under a local /home
that reaches a NAS through a symlink) it narrows to the stalled path.
- GET /api/cases/:name probes CLAUDE.md with pastCap, like the folder probe.
- Comment in config/path-probe.ts describes the mount-scoped stall.
The bounded path probe answered "absent" both when a path did not exist and
when it simply did not answer, so a stalled linked case 404'd and the Run
button scaffolded a stray local case over it, and two stalled paths anywhere
made every unrelated path read as absent (hooks skipped, statusLine
overridden, the clone warning lost).
- probePath()/probePathKind() are tri-state: present (or directory/file),
absent (ENOENT/ENOTDIR only) and unknown (timeout, other errors, refusal).
boundedPathExists() stays as the display-only boolean.
- A stalled path takes only its own mount out of probing (deepest mount
point from /proc/self/mounts, never /; just the path itself when there is
no mount table). Unrelated paths keep probing. The process-wide cap is a
backstop that answers unknown, and a single-path user request can probe
past it ({ pastCap: true }), still bounded and still recorded as stalled.
One console.warn when a path first stalls and one when the cap engages.
- GET /api/cases/:name keeps NOT_FOUND for definite absence only. An
unreachable linked case answers with its registered path and
unreachable: true; a local one answers OPERATION_FAILED. runClaude and
runShell create a case only on errorCode NOT_FOUND. The case list keeps an
unreachable linked case, marked unreachable, instead of dropping it, and
fix-plan reports an unreadable plan as an error, not "no plan".
- applyWorkspaceHooks and the statusLine helpers skip only a workspace that
is absent or on the stalled mount; a capacity refusal no longer stops
hooks being installed elsewhere, and an unreadable settings file never
lets the exporter override a user's own statusLine.
- The clone flow's repo-settings warning is back on its synchronous check,
and stripCaseEnvKeys uses pathExistsForWrite.
- POST /api/sessions (workingDir) and POST /api/quick-start (case folder)
probe with the bounded probe instead of statSync/existsSync. Missing and
non-directory keep INVALID_INPUT; unknown is OPERATION_FAILED, and
quick-start never scaffolds over a folder that did not answer.
- PATH_PROBE_TIMEOUT_MS and MAX_STALLED_PATH_PROBES move to
src/config/path-probe.ts, overridable via CODEMAN_PATH_PROBE_TIMEOUT_MS
(default 1500) and CODEMAN_PATH_PROBE_MAX_STALLED (default 3), and are
documented in the Settings Reference.
- The probe is exported from the utils barrel and imported from there.
A linked case can live on a network mount. When that mount goes away, a
hard mount makes stat() wait indefinitely, and the existsSync() probes in
the case routes and the workspace hook/statusline helpers ran on the event
loop, so a single GET /api/cases (or a session create in that workspace)
froze the whole web server until the mount came back.
Add boundedPathExists() (src/utils/bounded-path-probe.ts): an async stat
that answers "absent" after 1.5 s, shares one in-flight probe per path,
remembers a timed-out path until its stat finally settles, and refuses to
start new probes while two stalled ones still hold libuv threadpool
workers. Route the read-side probes in case-routes.ts and hooks-config.ts
through it. The settings writers in hooks-config.ts use an async lstat
that treats only ENOENT as missing, so an unreachable workspace is never
mistaken for an empty one and has its settings recreated.
