Two coupled changes that let downstream projects (eg. `modden`) inherit
the test-harness loglevel plumbing for free via
`tractor._testing.pytest`:
Plugin lift (`tests/conftest.py` → `_testing/pytest.py`),
- mv `pytest_addoption(--ll)`, the `loglevel` autouse
fixture, and `test_log` fixture out of the test-suite-
local conftest into the reusable plugin.
- add `--tl`/`--tractor-loglevel` as a DISTINCT flag from
`--ll`: `--ll` is the consuming-project's OWN app
loglevel (scoped to its pkg-hierarchy), `--tl` is the
`tractor.*` runtime loglevel. `--tl` falls back to
`--ll` when unset (preserves current `tractor`-suite
behavior).
- add `testing_pkg_name` session fixture (default
`'tractor'`) — downstream projects override to e.g.
`'modden'` so `--ll` scopes to their own hierarchy
instead of `tractor.*`.
- `loglevel` fixture now yields the resolved
tractor-runtime level (passed to
`open_root_actor(loglevel=<.>)` by `@tractor_test`)
AND separately applies `--ll` to the
`testing_pkg_name` hierarchy when that isn't
`tractor`. `test_log` scopes the per-test logger to
`testing_pkg_name`.
`tractor.log` "logging-spec" mini-DSL,
- `LogSpec = str|bool`. Accepted forms:
- `True` → enable `pkg_name` root at `default_level`
(fallback `'cancel'`).
- `False` → no-op.
- bare level eg. `'info'` → root-logger at that level.
- `'sub:info,x:cancel'` → per-sub-logger filter-spec;
each `<name>` is RELATIVE to `pkg_name` (must NOT
include the pkg-token).
- `parse_logspec()` → `{sublog|None: level}` mapping.
`None` key = root-logger. Mixed bare-level + filters
in one spec is rejected w/ a helpful err msg; so is
embedding the `pkg_name` token in a sub-name.
- `apply_logspec()` → `(primary_level, {name: log})`:
parses then enables a `colorlog` stderr handler per
named (sub)logger. Authoritative sub-logger filters
get `propagate=False` so they don't double-emit
through a parallel root-level handler.
- !GRANULARITY CAVEAT! sub-logger names match at
sub-pkg granularity, not leaf-module — so `devx.debug`
collapses to the same `tractor.devx` logger as a bare
`devx`, and top-level lib modules (eg.
`tractor.to_asyncio`) emit under the *root* logger
rather than a phantom `to_asyncio` child. Documented
inline on `LogSpec`.
Other,
- `tests/conftest.py` keeps a NOTE pointing to the
plugin for future-debugging clarity (don't remove
silently — the lift is the relevant signal).
