Add a hard process-level wall-clock bound on a test
known to wedge un-Ctrl-C-ably under an in-dev spawn
backend, so an unattended suite run can't hang
indefinitely.
Deats,
- New `testing` dep: `pytest-timeout>=2.3`.
- `test_stale_entry_is_deleted`:
`@pytest.mark.timeout(3, method='thread')`. The
`method='thread'` choice is deliberate —
`method='signal'` routes via `SIGALRM` which can be
starved by the same GIL-hostage path that drops
`SIGINT`, so it'd never actually fire in the
starvation case.
At timeout, `pytest-timeout` hard-kills the pytest
process itself — that's the intended behavior here;
the alternative is the suite never returning.

(cherry picked from commit 34d9d482e4)
(factored: kept only the pyproject dep-group parts of
"Raise `subint` floor to py3.14 and split dep-groups"; dropped
tractor/spawn/_spawn.py + tractor/spawn/_subint.py)
Since we're devving subints we require the 3.14+ stdlib API
and a couple compiled libs don't support it yet, namely:
- `cffi`, which we're only using for the `.ipc._linux` eventfd
stuff (now factored into `hotbaud` anyway).
- `greenback`, which requires `greenlet` which doesn't seem to be
wheeled yet
* on nixos the sdist build was failing due to lack of `g++` which
i don't care to figure out rn since we don't need `.devx` stuff
immediately for this subints prototype.
* [ ] we still need to adjust any dependent suites to skip.
Adjust `test_ringbuf` to skip on import failure.
Also project wide,
- pin us to py 3.13+ in prep for last-2-minor-version policy.
- drop `msgspec>=0.20.0`, the first release with py3.14 support.
(cherry picked from commit d2ea8aa2de)
Prep for a future sub-interpreter (PEP 734
`concurrent.interpreters`) spawn backend per issue
#379 — land just the py-version range bump and the
test-harness error-gating; the backend itself comes
later.
Deats,
- bump `pyproject.toml` `requires-python` to
`>=3.12, <3.15` and list the `3.14` classifier —
the new stdlib `concurrent.interpreters` module
only ships on 3.14
- `_testing.pytest.pytest_configure` wraps
`try_set_start_method()` in a `pytest.UsageError`
handler so an unsupported `--spawn-backend` on the
running py-version prints a clean banner instead
of a traceback

Thanks to the `tox`-dev community for such a lovely pkg which seems to
solves all the current cross-platform user-dir problems B)
Also this,
- now passes `platformdirs.user_runtime_dir(appname='tractor')`
and allows caller to pass an optional `subdir` under `tractor/`
if desired.
- drops the `.config._rtdir: Path` mod var.
- bumps the lock file with the new dep.
Namely to get a fix (i patched in) to `pdbp` and the latest
prompt-injection feats from `xonsh` B)
Also leave in a (masked) `.uv.sources.pdbp` section for easy
patch-test-submit in the future from my own fork and bump the lock file
to match!
Namely,
- `devx` for console debugging extras used in `tractor.devx`.
- `repl` for @goodboy's `xonsh` hackin utils.
- `testing` for harness stuffs.
- `lint` for whenever we start doing that; it requires special
separation on nixos in order to pull `ruff` from pkgs.
Oh and bump the lock file.
Oddly my env was borked bc a missing sub-dep (`typing-extensions`
apparently not added by `uv` for `stackscope`?) and then `stackscope`
was silently failing import and caused the shield-pause test to also
fail (since it couldn't match the expected `log.devx()` on console). The
import failure is not very explanatory due to the `log.warning()`;
change it to `.error()` level.
Also, explicitly import `_sync_pause_from_builtin` in
`examples/debugging/restore_builtin_breakpoint.py` to ensure the ref is
exported properly from `.devx.debug` (which it wasn't during dev of the
prior commit Bp).
Since it turns out there's a few gotchas moving to python 3.13,
- we need to pin to new(er) `trio` which now flips to strict exception
groups (something to be handled in a follow up patch).
- since we're now using `uv` we should (at least for now) prefer the
system `python` (over astral's distis) since they compile for
`libedit` in terms of what the (new) `readline.backend: str` will read
as; this will break our tab-completion and vi-mode settings in
the `pdbp` REPL without a user configuring a `~/.editrc`
appropriately.
- go back to using latest `pdbp` (not a local dev version) since it
should work fine presuming the previous bullet is addressed.
Lock bumps,
- for now use latest `trio==0.29.0` (which i gotta feeling might have
broken some existing attempts at strict-eg handling i've tried..)
- update to latest `xonsh`, `pdbp` and its dep `tabcompleter`
Other cleaning,
- put back in various deps "comments" from `poetry` content.
- drop the `xonsh-vox` and `xontrib-vox` dev deps; no `vox` support with
`uv` rn anyway..
Hasn't been needed for a while since the type-annots have been exposed
from core since `trio>=0.24`. Allows us to drop a buncha sub-deps as
well like,
- `async-generator`
- `importlib-metadata`
- `mypy-extensions`
- `typing-extensions`
- `zipp`
Yah, don't really know why i listed all those but..
Namely since i use `xonsh` for a main shell, this includes adding it as
well as related tooling. Obvi bump the `uv.lock`.
Some other stuff retained from `poetry` days,
- add usage-comments around various (optional) deps.
- add toml section separator lines.
- go with 2-space indent.
- add comment on `trio>0.27` needed for py3.13+
Since importing from our top level `conftest.py` is not scaleable
or as "future forward thinking" in terms of:
- LoC-wise (it's only one file),
- prevents "external" (aka non-test) example scripts from importing
content easily,
- seemingly(?) can't be used via abs-import if using
a `[tool.pytest.ini_options]` in a `pyproject.toml` vs.
a `pytest.ini`, see:
https://docs.pytest.org/en/8.0.x/reference/customize.html#pyproject-toml)
=> Go back to having an internal "testing" pkg like `trio` (kinda) does.
Deats:
- move generic top level helpers into pkg-mod including the new
`expect_ctxc()` (which i needed in the advanced faults testing script.
- move `@tractor_test` into `._testing.pytest` sub-mod.
- adjust all the helper imports to be a `from tractor._testing import <..>`
Rework `test_ipc_channel_break_during_stream()` and backing script:
- make test(s) pull `debug_mode` from new fixture (which is now
controlled manually from `--tpdb` flag) and drop the previous
parametrized input.
- update logic in ^ test for "which-side-fails" cases to better match
recently updated/stricter cancel/failure semantics in terms of
`ClosedResouruceError` vs. `EndOfChannel` expectations.
- handle `ExceptionGroup`s with expected embedded errors in test.
- better pendantics around whether to expect a user simulated KBI.
- for `examples/advanced_faults/ipc_failure_during_stream.py` script:
- generalize ipc breakage in new `break_ipc()` with support for diff
internal `trio` methods and a #TODO for future disti frameworks
- only make one sub-actor task break and the other just stream.
- use new `._testing.expect_ctxc()` around ctx block.
- add a bit of exception handling with `print()`s around ctxc (unused
except if 'msg' break method is set) and eoc cases.
- don't break parent side ipc in loop any more then once
after first break, checked via flag var.
- add a `pre_close: bool` flag to control whether
`MsgStreama.aclose()` is called *before* any ipc breakage method.
Still TODO:
- drop `pytest.ini` and add the alt section to `pyproject.py`.
-> currently can't get `--rootdir=` opt to work.. not showing in
console header.
-> ^ also breaks on 'tests' `enable_modules` imports in subactors
during discovery tests?
