Three inline context-manager classes shared the same __enter__/__exit__
boilerplate and differed only in the events yielded before the raise.
Also drop the unreachable 'or agent.base_url' fallback: every
anthropic_messages init path sets _anthropic_base_url, and the two
sibling call sites read it bare.
A tool_use block name recorded by a stream attempt that died before any
visible text survived into the next attempt: only the deltas_were_sent
mid-tool branch cleared result["partial_tool_names"]. When the retry then
streamed plain text and dropped, the partial stub blamed the stale tool
("Stream stalled mid tool-call (old_tool)") and the stale name could make
a later attempt look mid-tool-call when deciding whether the drop is
retryable. Reset it in _start_stream_attempt alongside
provider_tool_in_flight, which already has attempt-local semantics.
Regression: two-attempt stream (tool_use start + parse error, then text +
drop) — stub content and emitted deltas carry no stale tool name.
Follow-up to the cherry-picked fix: keep the classifier widening
("expected value at line" is now a transient stream parse error on the
main turn) but replace the messages.create() fallback with a retry on the
same stream wire.
Why not create(): the fallback ran outside Relay (lost request rewrites),
outside _handle_stream_error (could replace text already shown to the
user with a different generation), ticked no liveness events for the
whole buffered payload, and a bare identical retry still re-emits the same
malformed JSON.
Why not drop the fine-grained-tool-streaming beta (#108583/#109056): live
probe on claude-sonnet-4-5, ~500-line tool call - beta on: max inter-event
gap 1.6 s; beta off: 139 s zero-event gap while Anthropic buffers the
args, which the 180/240 s stale-stream detector kills on larger payloads
(the regression 80a899a8e2 fixed).
Instead, on a parse error the retry sets `eager_input_streaming: false`
on every tool for that request only (the SDK/API per-tool field overrides
the legacy beta header), so Anthropic returns buffered, server-validated
args while the happy path keeps fine-grained streaming. A tool_use that
started streaming is registered in partial_tool_names so the mid-tool
transient retry fires the same way it does on the chat_completions wire.
`scripts/run_tests.sh tests/<dir>/` is how a change gets its regression
coverage run, so a test filed under the wrong directory is a test nobody
runs when that code changes. Two kinds of drift had accumulated.
Parallel directories for one source package, folded into the mirror:
tests/acp -> tests/acp_adapter (its __init__/conftest move with it)
tests/cli -> tests/hermes_cli (prompt_toolkit fixture merged into
hermes_cli/conftest.py)
tests/run_agent -> tests/agent (backoff fixture becomes
agent/conftest.py)
tests/relay -> tests/gateway/relay
tests/state -> tests/hermes_state
246 loose files at tests/ root, routed by the package they import/patch:
hermes_cli, hermes_state, agent, gateway, tools, plugins, tui_gateway, cron.
Installer and desktop-update script tests go to tests/scripts/{install,
desktop_update}/. 43 tests of root-level modules (batch_runner, utils,
hermes_constants, packaging) stay at the root.
Filenames drop their issue numbers (95 files: test_89315_x.py -> test_x.py);
the number stays in the module docstring where it has context.
Collisions: test_cli_skin_integration.py existed in both tests/ and tests/cli
with different subsets — merged into one (10 tests, all kept);
run_agent/test_pre_compress_memory_context.py -> agent/..._handoff.py;
tests/test_account_usage.py -> agent/test_account_usage_fetch.py;
tests/test_web_server.py -> hermes_cli/test_web_server_ws_ping.py.
Deleted: test_minisweagent_path.py (empty since PR #2804),
test_model_picker_scroll.py (tested a private copy of the logic, imported
nothing), test_process_loop_event_loop_warning.py (asserted asyncio behaviour,
imported nothing from Hermes).
Repo-root path arithmetic (Path(__file__).parents[N], dirname chains) is
bumped for the 202 files that changed depth and verified by evaluating every
such expression against the new location. classify_changes' desktop-updater
lane prefix, tests-os.yml's ignore glob and every in-tree path comment follow
the moves. tests/test_tests_tree_layout.py keeps the tree from drifting back.
