Broken/incompatible `--skip-missing-interpreters false` behavior since 4.1.2 #2811

scop · 2023-01-03T20:53:46Z

Issue

Since tox 4.1.2, tox --skip-missing-interpreters false -e someenv seems to want interpreters present also for envs that are not invoked.

Up to 4.1.1, since from I don't remember when (3.x a long time ago), this used to work the way I'd assume: fail on missing interpreters only for environments that are actually going to be used. 4.1.2..4.1.3 have the problem.

Environment

Provide at least:

OS: Linux
pip list of the host Python where tox is installed:

@q0w this could be a bug with #2793

q0w · 2023-01-03T22:19:46Z

I'll try to fix

q0w · 2023-01-03T23:52:53Z

why with use_develop tox ignores raise Skip exceptions and continues the execution?
upd: because it's handled in _build_pkg_env

q0w · 2023-01-04T00:19:27Z

I tested with tox<4.1.2 and with use_develop it continues the execution and then fails with:

...
AttributeError: 'NoneType' object has no attribute 'version_info'
  py33: FAIL code 2 (0.00 seconds)
  evaluation failed :( (0.24 seconds)

Something is wrong with an editable installation

Yes, that seems to be another bug, it apparently throws that for interpreters that are not present. But I thought I'd try to keep the report in scope and have just one thing in it.

* Update swift from branch 'master' to f77172e2ad6fef4b226637b8ae099a6faf810978 - CI: pin tox at the project level No sooner do we fix the gate than tox has a new release that breaks it again. Let's give them a bit to settle down; in the mean time, stick with 3.x. See tox-dev/tox#2811 Also simplify our warning suppressions. The message filter is a regex, so any prefix of the message will suffice. This allows us to also drop a new message seen on CentOS 8: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography (40.0) will be the last to support Python 3.6. As we've previously seen with cryptography warnings, this can slow down our probe tests to the point that they time out. Change-Id: I316170442c67c1b4a5b87f9a1168cc04ca2417b8

Patching like this would fix the problem with use_develop

     def child_pkg_envs(self, run_conf: EnvConfigSet) -> Iterator[PackageToxEnv]:
-        if run_conf["package"] == "wheel":
+        if run_conf["package"] in {"wheel", "editable"}:
             env = self._wheel_build_envs.get(run_conf["wheel_build_env"])
             if env is not None and env.name != self.name:
                 yield env

but tox would fail with default wheel_build_env cause NoInterpreterFound/Skip are not handled here

We now separate environments into either run or packaging environments [1]. As noted in 'tox.session.env_select.EnvSelector._defined_envs' [2], the name of the environment is not enough to determine what type of environment it is and we must actually build the environment and inspect it. This allows us to prevent users *running* these packaging environments (e.g. 'tox -e .pkg'). Part of this process of building an environment is validating the base python. If this validation fails (i.e. the Python version does not exist), we will raise 'tox.tox_env.python.api.NoInterpreter'. We were not handling this exception, and thus the process of determining the types of each environment would cause a failure if any environment requested a Python version we did not support, even if we weren't actually trying to run this environment. The fix for this is simple: handle the exception and simply ignore these unsupported environments. While we're here, fix some issues with an existing test that were noticed while adding new tests.
