* test: deflake CI and dev-machine flaky tests in bulk
Fixes ten distinct flake sources found by mining recent CI failures and
running the full suite on a dev machine with real user state:
CI-observed races:
- tests/conftest.py live-system guard: allow signal 0 (pure liveness
probe) through _guarded_kill/_guarded_killpg. psutil.pid_exists()
probes a just-killed grandchild reparented to init; the subtree check
fails for it and the guard RuntimeError'd
test_entire_tree_is_sigkilled_not_just_parent intermittently on
unrelated PRs.
Hermeticity flakes (fail on dev machines with real state, pass on CI):
- agent/coding_context.py: _marker_root() now skips the shared temp
root (tempfile.gettempdir()) like it skips $HOME — a stray
/tmp/package.json flipped every tmp_path test into the coding
posture (9 failures in test_coding_context.py).
- test_agent_guardrails.py: pin MAX_CONCURRENT_CHILDREN=3 via autouse
monkeypatch instead of freezing the user's real config value at
import time (import-time vs call-time config mismatch).
- test_web_tools_config.py: TestCheckWebApiKey now neutralizes the
ddgs package probe and registry providers — the optional ddgs
package in a dev venv lit up the fallback backend.
- test_credential_pool.py: block claude_code/hermes-oauth credential
autodiscovery in the two pool-merge tests that assert exact id
lists (a real ~/.claude/.credentials.json seeded an extra entry).
- test_modal_sandbox_fixes.py: clear _permanent_approved /
_session_approved — the user's real command_allowlist silently
approved the guard-escalation commands under test.
- test_setup_irc.py: stub prompt_checklist to select only the IRC row;
the non-TTY cancel fallback re-ran the real configured platforms'
interactive setup_fn, which hit input() under captured stdin.
- test_doctor.py: TestGitHubTokenCheck now patches the module-level
HERMES_HOME constant (the file's established pattern) instead of
only setenv — doctor was running PRAGMA integrity_check against the
real multi-GB state.db and blowing the 300s per-file budget.
Latent atexit-duplication (same _enter_buffered_busy class as #34217):
- test_undo_command.py: drop importlib.reload(tui_gateway.server) in
fixture teardown; reload re-registers the module's atexit hooks.
- test_session_platform_resolution.py: drop per-test reload of
tui_gateway.server; every resolver reads env at call time.
* test: sentinel model value in ignore-user-config fallback assertion
With HERMES_IGNORE_USER_CONFIG=1, load_cli_config() falls back to the
repo-root cli-config.yaml (untracked, gitignored). On a dev machine that
file can legitimately set the same popular model the test hardcoded
(anthropic/claude-sonnet-4.6), flipping the != assertion locally while
CI (no cli-config.yaml) stayed green. Use an impossible sentinel model
name instead.
_sanitize_api_messages() compared raw tool_call_id strings without
stripping whitespace. When assistant-side IDs and tool-result IDs
diverged due to surrounding whitespace, valid tool results were treated
as orphaned and replaced with [Result unavailable] stub placeholders.
Strip whitespace in _get_tool_call_id_static() (both call_id/id paths,
dict and object) and at the two result_call_id comparison sites in
sanitize_api_messages(). Adds regression tests for preserved-whitespace
results and orphaned-whitespace removal.
Closes#9999
Gemini's OpenAI-compatibility endpoint strictly requires the `name` field
on `role: tool` messages — it returns HTTP 400 ("Request contains an
invalid argument") when the function name is missing. OpenAI/Anthropic/
ollama tolerate the absence, so the gap stays invisible until the
conversation accumulates a tool turn and the user routes it through Gemini
(direct API or via ollama-cloud proxy).
Fix: add a `_get_tool_call_name_static()` helper alongside the existing
`_get_tool_call_id_static()`, and populate `name` at every site that
constructs a `role: tool` message — the pre-call sanitizer stub, the
tool-call args repair marker, both interrupt-skip paths, both
result-append paths (parallel + sequential), the invalid-tool-name
recovery, the invalid-JSON-args recovery, and the exception fallback.
Each call site was already in scope of the function name (`function_name`,
`skipped_name`, `name`, or a dict tool_call), so the change is local —
no new lookups, no behavior change for providers that already worked.
Fixes#16478
`delegate_task` silently truncated batch tasks to 3 — the model sends
5 tasks, gets results for 3, never told 2 were dropped. Now returns a
clear tool_error explaining the limit and how to fix it.
The limit is configurable via:
- delegation.max_concurrent_children in config.yaml (priority 1)
- DELEGATION_MAX_CONCURRENT_CHILDREN env var (priority 2)
- default: 3
Uses the same _load_config() path as the rest of delegate_task for
consistent config priority. Clamps to min 1, warns on non-integer
config values.
Also removes the hardcoded maxItems: 3 from the JSON schema — the
schema was blocking the model from even attempting >3 tasks before
the runtime check could fire. The runtime check gives a much more
actionable error message.
Backwards compatible: default remains 3, existing configs unchanged.
* refactor: re-architect tests to mirror the codebase
* Update tests.yml
* fix: add missing tool_error imports after registry refactor
* fix(tests): replace patch.dict with monkeypatch to prevent env var leaks under xdist
patch.dict(os.environ) can leak TERMINAL_ENV across xdist workers,
causing test_code_execution tests to hit the Modal remote path.
* fix(tests): fix update_check and telegram xdist failures
- test_update_check: replace patch("hermes_cli.banner.os.getenv") with
monkeypatch.setenv("HERMES_HOME") — banner.py no longer imports os
directly, it uses get_hermes_home() from hermes_constants.
- test_telegram_conflict/approval_buttons: provide real exception classes
for telegram.error mock (NetworkError, TimedOut, BadRequest) so the
except clause in connect() doesn't fail with "catching classes that do
not inherit from BaseException" when xdist pollutes sys.modules.
* fix(tests): accept unavailable_models kwarg in _prompt_model_selection mock
