Renaming a profile moved profiles/<old>/ to profiles/<new>/, so the row DATA
travelled with the directory, but the profile name is also baked into
keys/values the move left untouched: session keys (agent:<old>:* namespace),
sessions.profile_name (fail-closed owner ladder / Desktop sidebar scope /
@session: deep links), sessions.origin_json.profile,
gateway_heartbeats.profile, delivery_obligations (session_key +
adapter_profile), telegram_dm_topic_* profile_name bindings, and the
gateway_routing index. Left stale, every inbound event on a chat keyed to the
old name resolved to a profile that no longer exists — flooding errors.log
with "Profile <old> does not exist ... falling back to global HERMES_HOME"
every few seconds — and renamed sessions dropped out of the sidebar / broke
their deep links.
The routing index is held in memory by a live multiplexer and written back
periodically, so a CLI-side DB rewrite alone is clobbered. Fix in layers:
- SessionDB.rekey_profile_state: atomic durable rewrite of the state.db
tables, matching the agent:<name>: namespace by exact prefix (substr, not
LIKE — '_' is a legal profile-name character and a LIKE wildcard), rewriting
the profile inside routing/origin JSON, and REFUSING on a target collision
(routing rows or telegram bindings) instead of silently merging.
- SessionStore.rekey_profile_routing: rekey the in-memory routing index
(keys + origin.profile) then persist — the half a DB write cannot reach.
Raises on a target-key collision before mutating.
- Control verb migrate-profile-identity (params-carrying; the socket passes
params only to handlers that declare them, bare handlers unchanged) so a
live gateway rekeys its in-memory copy AND both durable stores (routing home
+ the renamed profile's own state.db).
- rename_profile calls the verb when a multiplexer is live and, if it fails,
does NOT fall back to a racing CLI-side write: it prints a warning telling
the operator to restart the gateway and retry. With no live gateway it
performs the durable rewrite itself (safe: nothing else holds the store
open).
Checkpoints keyed by the profile's workdir path are a known related gap,
tracked separately, not addressed here.
Tests: rekey_profile_state (all tables, routing/origin JSON, collisions,
idempotent, no-op), rekey_profile_routing (namespace + origin, no-op, no
overwrite), control verb param passing, and rename end-to-end for both the
live-gateway (delegates, refuses unsafe fallback) and no-gateway (durable
rewrite) paths.
A `gateway.multiplex_profiles` gateway enumerated `profiles/` once at boot, so a profile
created afterwards (CLI, dashboard, Desktop, TUI) was never served until `hermes gateway
restart`; Desktop and the dashboard gave no reminder, so a new profile's bot simply never
connected.
The served set is now reconciled at runtime (`gateway/run_profile_reconcile.py`):
- `hermes_cli/profiles.py` create/delete ping the multiplexer over its control socket
(new `rescan-profiles` verb); a supervised watcher rescans every 30s as the safety net.
- A new profile gets its adapters under its own runtime scope from its config/.env
(`_start_one_profile_adapters`, same duplicate-credential guard as boot, now seeded
with the LIVE secondaries' claims), `served_profiles` in gateway_state.json is
updated, MCP discovery + log routing run for it. Other profiles' adapters are never
touched.
- A served profile whose config.yaml/.env changed is re-scanned so a token added after
create builds the adapter; already-live/queued platforms are skipped (no second poller).
- A deleted profile (tombstone) has its reconnects cancelled, adapters torn down,
pairing/busy bookkeeping and cached agents dropped, and this process's SQLite /
memory-store handles released so the deleter's rmtree succeeds.
- The in-process cron ticker takes a live enumerator so new profiles' jobs fire.
- PUT /api/messaging/platforms/<id>?profile=X returns `hot_served` when a live
multiplexer rebuilt X's adapters; Desktop/dashboard skip the restart banner then.
- `hermes profile create` confirms hot-serve; the restart reminder stays for a gateway
that did not pick the profile up (older build / signal failed).
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Windows updates forced a choice between 'gateway survives' and 'update
proceeds': the pause machinery's only tools were the planned-stop marker
poll and the force-kill ladder, so a mid-turn gateway was tree-killed and
its active turn lost. Step 2 of the socket migration adds the
pause-for-update verb: the updater ASKS the gateway to drain in-flight
turns and exit cleanly — releasing every venv file handle on the way out
— through the same request_restart(via_service=True) drain path SIGUSR1
and service restarts already use.
- gateway/run.py: pause-for-update verb handler registered on the
existing control server; marshals onto the loop thread, ACKs with
{pausing, already_stopping, pid, drain_timeout}.
- gateway/control_socket.py: pause_gateway_for_update() client — None on
no-answer (older gateway / no socket), so every caller keeps the
legacy path when the verb is missing.
- update_cmd.py (_pause_windows_gateways_for_update): socket-first ask
per mapped profile gateway before the drain wait; positive ACKs extend
the wait to the gateway's own declared drain budget (+ teardown grace)
so a mid-turn gateway isn't force-killed at the end of a too-short
local default. Marker write + force-kill ladder retained verbatim as
the fallback.
Live E2E: real gateway process (isolated HERMES_HOME), real socket:
identify -> pause ACK {pausing: true} -> gateway drained and exited on
its own (rc=75, zero signals) -> dead-gateway re-ask returns None.
A step-1 gateway without the verb answers ok:false -> client None ->
legacy path (pinned by test).
- bind under umask 0o177 so the socket is never world-connectable, even
pre-chmod (review pt 3)
- verb handlers run in an executor: state-file reads stay off the
adapter event loop (pt 2)
- inventory dedupes one multiplex gateway answering identify for several
homes — one runtime record per pid, with regression test (pt 1)
- v1 wire contract (one request per connection) documented in the module
docstring (pt 5); /tmp-unwritable skip in the short-home test
Live-verified: perms 600 at bind, identify 4.3ms via executor path, 20
rapid queries healthy.
CI runners put pytest tmp roots past sun_path, which routed every test
home through the fallback: two tests assumed in-home binding. Tests now
assert against the resolved bind location, and the fallback itself
prefers /tmp when tempfile.gettempdir() is too deep to fit sun_path.
The gateway now creates a local control socket at startup (Unix domain
socket at $HERMES_HOME/gateway.sock with a pointer-file fallback for
long paths; named pipe on Windows) and answers versioned JSON verbs:
- identify: pid, profile, hermes_home, code_sha/code_version (#91283
stamps, now queryable live), self-declared supervisor kind, start_time
- status: the live runtime-status payload, answered by the process itself
Bound immediately after the PID-file O_EXCL claim (the moment the
process becomes the authoritative gateway for its HERMES_HOME), removed
on clean shutdown; a successor clears any stale socket on bind. Strictly
non-fatal: bind failure only means consumers use the old path.
Consumers migrated (observability only, scan layer demoted to fallback,
never deleted):
- collect_fleet_versions() (post-update fleet matrix): prefers a live
identify answer over gateway_state.json; entries carry source=socket
- collect_runtime_inventory() (hermes update --plan): prefers the
socket, and takes the gateway's own supervisor declaration instead of
inferring it from PID scans
Old gateways mid-upgrade, crashed processes, and bind failures behave
exactly as before. Never a TCP port; filesystem/pipe ACLs are the auth
boundary (0600 socket).
Part of #91277 (fleet-update reliability). Design: #92091.
