This adds RHEL8's `/usr/libexec/platform-python` to Spack's list of preferred
pythons. It will only be used if no other `python` is available in the `PATH`.
We have been testing with this python for a while now, and it seems to do all
that we need. If Spack one day isn't able to work with it, we'll take it out,
but for now it is useful to allow Spack to be used on RHEL8 without a dedicated
`python` installation.
Clingo has been released on PyPI, so there
are no more concerns on our CI depending
on pypy.test for installing the wheel.
Apparently we have parts of Spack which
are not compatible with kcov > 3.4
* QA: reduce number of unit tests for jobs not in the matrix
* Fixup for CentOS6 dependencies
* Put correct conditions back in place
* Add dependency on changes
PRs that change only package recipes will only run tests under "package_sanity.py" and without coverage. This should result in a huge drop the cpu-time spent in CI for most PRs.
* unit tests: mark slow tests as "maybeslow"
This commit also removes the "network" marker and
marks every "network" test as "maybeslow". Tests
marked as db are maintained, but they're not slow
anymore.
* GA: require style tests to pass before running unit-tests
* GA: make MacOS unit tests fail fast
* GA: move all unit tests into the same workflow, run style tests as a prerequisite
All the unit tests have been moved into the same workflow so that a single
run of the dorny/paths-filter action can be used to ask for coverage based
on the files that have been changed in a PR. The basic idea is that for PRs
that introduce only changes to packages coverage is not necessary, this
resulting in a faster execution of the tests.
Also, for package only PRs slow unit tests are skipped.
Finally, MacOS and linux unit tests are now conditional on style tests passing
meaning that e.g. we won't waste a MacOS worker if we know that the PR has
flake8 issues.
* Addressed review comments
* Skipping slow tests on MacOS for package only recipes
* QA: make tests on changes correct before merging
