Three surfaces start updates against one checkout: a terminal
"hermes update", the dashboard's Update button (which spawns that same
command detached), and the desktop's, which hands off to the Tauri
updater. Only the Tauri updater published the in-progress marker, and
only Electron read it -- to gate backend startup, not to stop a second
updater. So a dashboard-spawned update and an installer-driven git
checkout could mutate the same tree concurrently, rewriting source under
a live interpreter.
Claim the same marker from cmd_update rather than adding a second
mechanism: same path, same pid+started_at payload the Rust and Electron
readers already parse. A marker only counts as live when its pid is alive
and it is inside the shared age ceiling, so a crashed updater self-heals
instead of wedging every future update. Release only removes a marker we
still own, leaving a handoff partner's claim intact.
Refusing exits 2, matching the existing concurrent-instance contract the
Tauri updater already recognizes.
Main's 243c9182b1/a16fd675df/7142dc4580 added load_config_readonly
sibling stubs across 38 files; our pruned versions of 11 of those files
kept only the load_config stubs. Re-applied the pairing at every
surviving site (26 patch()/setattr sites) — same return_value/
side_effect as the adjacent load_config stub. 494 tests green across
the 11 files.
hermes-setup.exe bakes its build-time commit into the binary
(BUILD_PIN_COMMIT) and passes it as -Commit on every install-mode run,
including the retry the desktop's "Update didn't finish" screen kicks
off. The repository stage checked that SHA out unconditionally, so an
installer built months earlier rewound a current managed checkout to its
build commit -- 9,160 commits in the reported case -- leaving ancient
source against a current venv. npm then failed on workspaces that did not
exist yet at that commit, and every later update ran against the wrong
tree.
Skip the pin when its target is already an ancestor of HEAD. Fresh clones
have no such ancestry so reproducible/CI pinning is unchanged, and
--force-commit / -ForceCommit still rolls back on purpose.
The #71637 prune fix cut one stage of -w startup, but the base-ref
resolution right after it still ran an uncapped-in-practice
'git fetch origin main' (timeout=30) on every launch — and on a flaky
smart-HTTP connection that fetch intermittently stalled to the full 30s,
then cascaded into step 2's SECOND 30s fetch. Measured: back-to-back
fetches of 0.9s, 1.0s, 63.5s on the same box with healthy TLS (~185ms).
_resolve_worktree_base now:
- skips the fetch entirely when FETCH_HEAD is < 5 min old and the
tracking ref exists (repeat launches pay zero network cost)
- caps the fetch at 5s and falls back to the locally-known tracking
ref (labelled 'cached') on timeout/failure instead of cascading into
a second fetch — genuine staleness stays backstopped by the pre-push
stale-base gate
- caps 'git remote show origin' the same way
Worst case drops ~60s -> ~5s; warm path is ~0.02s (was up to 30.8s).
sync_base=False and the offline HEAD fallback are unchanged.
The change watcher (#73673) missed one always-on-while-mounted timer: the
Messaging page polled /api/messaging/platforms every 6s for connection
status. The gateway already persists platform connect/disconnect/health to
gateway_state.json, so watch that file's mtime and broadcast
platforms.changed (floored to 5s — the gateway also rewrites the file for
in-flight-count bookkeeping), route it through live-sync like its
siblings, and refresh the page on the tick. Older backends keep the
legacy visible-tab poll verbatim.
Finishes the always-on poll sweep for #73618.
Final pass: per_model_threshold_init_ordering, memory_provider_init,
plugin_context_engine_init, api_max_retries_config,
invalid_context_length_warning, tool_call_guardrail_runtime all stub
agent_init config reads that now resolve through load_config_readonly().
Verified by running the complete 59-file suspect list (every test file
that stubs load_config in string or attribute form and intersects the
swapped modules): 3,063 tests, 0 failed.
Second stub shape the first sweep missed: monkeypatch.setattr(config_mod,
"load_config", ...) — attribute-form instead of string-form. Four files
(compression_max_attempts, preflight_compression_cap_e2e,
codex_gpt55_autoraise_notice, proactive_prune_config) stub agent_init
config reads that now go through load_config_readonly(). Swept the whole
tree for the attribute form; remaining hits stub modules that still use
the mutable loader. 1,210 tests green across the 19-file re-sweep.
The readonly swaps mean agent/ modules now read config through
load_config_readonly(); tests that stubbed only load_config stopped
intercepting those reads. Added sibling readonly stubs (same
return_value/side_effect/lambda) at every affected site across 11 test
files, found via a tree-wide sweep of load_config stubs cross-referenced
against the swapped modules. 3,915 tests green across the 38-file
sibling sweep.
agent_init's config reads now go through load_config_readonly(); 8
tests that stubbed only load_config stopped intercepting them. Each of
the 10 patch sites gains a sibling readonly patch with the same
return_value. 461/461 file-local tests green.
Pins the audit findings: normalizer never mutates its input
(api_key_env + camelCase forms), providers-dict round-trips leave a
cached config byte-identical, and the normalized models mapping does
not alias the caller's dict.
The normalizer writes alias keys into the entry it is given
(entry['key_env'] = entry['api_key_env'] and entry[snake] =
entry[camel]) while building its normalized copy. Two of its three
callers — get_compatible_custom_providers and
providers_dict_to_custom_providers — pass live sub-dicts straight
from load_config_readonly()'s shared cache (only
_custom_provider_entry_to_provider_config defends with dict(entry)).
A config written with the documented camelCase / api_key_env aliases
therefore gets its cached copy polluted with injected duplicate keys,
violating the cache's explicit no-mutation contract; every later
load_config() deepcopy inherits the duplicates, and any
save_config(load_config()) flow (setup wizard, dashboard writes,
model persist) writes them back to config.yaml. The aux-client TLS
resolution runs this on every auxiliary client build, so the
mutation also happens unlocked on worker threads against a shared
object.
Shallow-copy the entry up front; the function's return value is a
separately-built dict, so behavior is otherwise unchanged.
The 1.0s sleep between sequential tool calls has been present since the
initial commit with no documented rationale. It sleeps between local
tool executions — the next LLM request goes out only after the whole
batch — so it rate-limits nothing, and the parallel read-only path
already runs with no delay. Every multi-tool turn pays (N-1) seconds
of dead time. Remove the sleep, the internal tool_delay plumbing, and
dead test assignments. AIAgent.__init__ keeps tool_delay as a
deprecated no-op keyword for one release so existing programmatic
callers construct cleanly; passing it emits a DeprecationWarning.
- Remove tests/-shadowing sys.path.insert(dirname/'..') from 11 test files:
it prepended the tests/ dir itself to sys.path, so 'import agent' /
'import hermes_cli' resolved to the test packages and collection died
with ModuleNotFoundError depending on import order (2 files failed in
every full-suite run; 9 more were latent).
- Patch call_llm in 5 context-compressor tests that called compress()
unmocked: each burned ~50s attempting live LLM traffic through the
relay before falling back (572s file — the slowest in the suite, and
flaky under the 300s per-file timeout). File now runs in ~5s.
- agent/redact.py: fix two catastrophically-backtracking regexes hit by
the compressor's redaction pass on large payloads —
_STRICT_URL_USERINFO_RE anchors on the mandatory '//' (optional-scheme
prefix backtracked O(n^2): ~55s on a 320KB payload, now sub-ms;
output-equivalence fuzz-verified on 20k random strings), and the
_CFG_DOTTED_RE/_CFG_ANCHORED_RE subs gain an exact linear keyword
pre-gate so secret-free text skips the quadratic pattern entirely.
- tests/gateway/test_feishu.py: version-guard the extra_ua_tags SDK
signature check; the repo pins lark-oapi==1.6.8 but stale local
installs (1.5.3) fail the assertion — skip below the pin.
- tests/tools/test_managed_browserbase_and_modal.py: stub
agent.redact + agent.credential_persistence in the fake agent package
(empty __path__ blocks all real agent.* imports added since the fake
was written).
- tests/gateway/test_startup_restart_race.py: raise wait_for timeouts
2s -> 30s; 2s wall-clock on a loaded 40-worker box flaked in the
baseline run (passes instantly when the box is quiet).
_stop_mcp_loop() stopped and closed the background loop without reaping
the tasks still on it. A task left suspended is resumed later by the GC,
whose finalizer drives its cleanup against the now-closed loop:
Exception ignored in: <coroutine object MCPServerTask.run ...>
File "tools/mcp_tool.py", line 2947, in run
parked = await self._wait_for_reconnect_or_shutdown(
File "tools/mcp_tool.py", line 2161, in _wait_for_reconnect_or_shutdown
t.cancel()
RuntimeError: Event loop is closed
shutdown_mcp_servers() only reaps servers held in _servers, so a server
that parked after exhausting its initial-connect budget — never inserted
there, because start() raises _error before the caller registers it — has
no owner to signal it and stays suspended until the loop is gone.
Drain the loop the way asyncio.run() does: cancel the remaining tasks and
gather them while the loop is still open, so each runs its own finally.
Cancel alone is not enough — Task.cancel() only schedules the throw.
This resolves the reported traceback, but not the ownership bug that
strands the task in the first place; that needs a follow-up. Deliberately
not using "Fixes" so #60197 stays open for it.

Second, deeper pass over tools/gateway/hermes_cli plus first pass over
the trees wave 1 missed (acp, acp_adapter, skills, computer_use, docker,
dashboard, conformance, monitoring, secret_sources, hermes_state,
providers). Same rubric as wave 1 (AGENTS.md test policy); security,
alternation/caching invariants, issue-number regressions, and E2E kept.
Real test-quality fixes found and rooted out along the way:
- tests/tools/test_command_guards.py made real auxiliary-LLM HTTPS calls
(DEFAULT_CONFIG smart-approval leaked in) — pinned approval
mode=manual via autouse fixture: 17.4s → 0.4s.
- test_model_switch_custom_providers.py / test_user_providers_model_switch.py
silently probed live provider catalogs (~2s/test) — stubbed
cached_provider_model_ids/provider_model_ids/fetch_api_models.
- test_telegram_noise_filter.py: 15-platform copy-paste matrix over
shared gateway.run logic → 3 representative platforms (55s → 3.9s).
- test_gateway_shutdown.py: stop()'s 5s interrupt-deadline loop spun on
MagicMock agents — interrupt.side_effect now clears _running_agents
(22s → 1.0s).
- test_gateway_inactivity_timeout.py poll-harness timings shrunk 3-5x
(24s → 1.1s); test_mcp_stability.py backoff/SIGTERM-grace sleeps
patched (15.4s → 2.5s); test_async_delegation.py negative-drain wait
5s → 0.5s.
- test_telegram_init_deadline.py: loop-block margin restored to 1.0s
with rationale comment — the watchdog-dump assertion needs the loop
blocked well past deadline+grace under parallel load (flaked once in
the 40-worker verification run at a 0.2s margin).
Verification: full hermetic suite via scripts/run_tests.sh —
2,438 files, 21,718 tests passed, 0 failed, 293.9s wall.
Suite totals vs original baseline: 46,820 → 19,757 test functions
(−57.8%), wall 583.5s → 293.9s (−50%), subprocess CPU 13,564s → 11,623s.
Resolves the PR's conflict with main (2252 commits). Two conflicts, both
"each side added an independent block in the same place" — kept both:
- gateway/run.py — the housekeeping loop. This branch adds the Skill Sync
pulls inside the CURATOR_EVERY branch (12-space indent); main adds a
stale-session auto-archive as a sibling `if` at loop level (8-space).
Different scopes, so the naive union would have mis-nested the archive
block into the curator branch; kept each at its own indent level.
- tools/skill_manager_tool.py — the _edit_skill result dict. This branch
appends the org auto-propose note; main appends
_add_description_prompt_preview(). Independent, order-insensitive.
No behaviour dropped from either side.
Verified: 3552 passed / 0 failed across 63 suites (scope regenerated to
include main's new maybe_auto_archive / _add_description_prompt_preview
consumers) via scripts/run_tests.sh. `hermes sync` and `hermes sync status`
still work against a live token, resolving the production plane default.
The Pyright Optional-parameter warnings in skill_manager_tool.py are
pre-existing on main (`content: str = None` etc.), not introduced here.
Salvaged from #31671 (@Shizoqua). The config-cache half of that PR was
superseded on main (9b8b054c2d gave _load_config_safe a readonly path),
but this cron-scanner half is still live: _strip_cron_safe_constructs
used re.search + a single str.replace, which only scrubbed occurrences
IDENTICAL to the first match. A cron job loading several GitHub skills
carries heterogeneous auth-header curl forms (-H vs --header, quoting,
token var names) — every non-identical block tripped the
exfil_curl_auth_header detector on every tick, blocking legitimate
GitHub cron jobs.
Now re.sub scrubs every occurrence; the trailing [^\n]* consumes the
URL path so no dangling fragment remains. Sabotage-verified: the old
implementation false-blocks the heterogeneous two-skill prompt the new
regression test pins; exfil to a non-GitHub host is still blocked.
79/79 cron tool tests green.
A transport error during the post-terminal SSE drain (used only to let the
Relay transport finalize the attempt) was sharing exception handling with
the pre-terminal assembly path, so it discarded an already-completed,
already-billed response and opened a brand-new physical request. Give the
drain step its own non-fatal error handling: log a finalization warning
and still return the terminal response.
Closes#74310
Follow-up to the #68246 salvage. The backend permission-mode resolution
only checked the DB session_id the tool path passes, but gateway /yolo
keys approval bypass off the gateway session_key (contextvar). Consult
both namespaces so /yolo works on messaging platforms, not just CLI/TUI.
Adds a regression test driving the real approval contextvar + yolo
toggle path E2E.

The earlier scrub covered adapter.py; nine internal QA-campaign tracker IDs
remained in the two new test files, including a module docstring and an
assertion message. They mean nothing to a future reader — describe the
behavior instead. Comments only, no assertion changes.
Both relay Slack knobs read their value through bool(), while the native
adapter they mirror uses str(raw).strip().lower() in {"1","true","yes","on"}.
A YAML-quoted string diverges:
dm_top_level_threads_as_sessions: "false" → relay True, native False
Non-empty strings are truthy, so the escape hatch is silently ignored in
exactly the shape an operator writes to switch it OFF. reply_in_thread has the
same defect and gates reply placement, session keying and run.py's progress
resolver, so one quoted "false" misfires three ways.
Route both through a shared _coerce_flag mirroring native's predicate. Real
booleans pass through untouched; None falls back to the default. Contract §8
documents the accepted spellings.
Tests: both knobs parametrized over the true/false spellings native accepts,
plus the absent-key default.
The DM thread-anchor contract was resolved only in send(). _send_media() —
backing send_image, send_image_file, send_voice, send_video and send_document
— passed reply_to straight to the frame and never touched metadata, so
attachments egressing through the same connector-side Slack sender got both
failure shapes this branch set out to remove:
flat mode → reply_to survives, the image threads UNDER the user's DM
message (the original reported symptom)
thread mode → no metadata.thread_id, and threadTs() never reads reply_to,
so the image lands in the home channel instead of the
per-message thread
Both are reachable: gateway/run.py delivers agent artifacts through
send_voice/send_document.
Extract the three steps that must always happen together (mode gate, mirrored
reply_to_message_id strip, metadata promotion) into
_apply_slack_thread_anchor and route BOTH lanes through it, so text and media
cannot drift again. The media lane copies caller metadata rather than mutating
it — these helpers are called in loops with a shared mapping.
Also fold send_typing/stop_typing's duplicated status-anchor blocks into
_with_status_thread_anchor. They had already drifted (stop_typing omitted the
platform check) and the clear must target the thread the heartbeat set or the
status line sticks until Slack's own timeout.
Tests: media lane pinned in both modes plus the channel and
no-caller-mutation cases; verified as real by reverting the fix and watching
them fail.
Three provably-safe optimizations for O(n)-per-iteration history walks:
1. sanitize_tool_call_arguments: optional identity-keyed cursor (strong
refs to the exact validated message objects) skips re-json.loads-ing
already-validated history each loop iteration. Any list rewrite
(compression, repair, undo, steer) breaks the identity prefix match
and forces re-scan from the divergence point. Wired via a per-agent
cursor dict in conversation_loop.
2. estimate_messages_tokens_rough: per-message memo keyed on a deep
identity fingerprint (strings pinned by strong reference so id()
aliasing is impossible; scalars by value; dicts/lists structurally
with key order). Equal fingerprints imply identical str(shadow)
bytes, hence identical estimates. Unfingerprintable shapes fall
through to direct compute. Bounded FIFO cache (4096 entries).
3. _flush_messages_to_session_db_unlocked: bounded scan that skips the
identity-matched prefix of the previous successful flush's snapshot.
Snapshot only taken on full success; cleared on exception. Compression
rewrites use fresh copies, breaking identity and forcing full re-scan.
Parity proven in tests/agent/test_cursor_optimizations_parity.py:
500-message synthetic histories with tool calls, malformed args, unicode,
element-wise old==new across 3 iterations incl. simulated compression.
Measured (median of 5): sanitize 0.097ms->0.011ms, tokens 1.145ms->0.853ms,
persist-scan 179.5us->10.0us at 500 messages.
