Since this is a kernel module, this needs to be added
to be added to linux-kernels.nix so that it can be
built for specific kernel versions
Appended the kernel make flags.
Set a minimum kernel version of 5.15 since it's failing to build on
older kernels.
This adds `pkgs.translatelocally-models.*` providing machine
translation models which can be used with `pkgs.translatelocally`.
`translatelocally-models.is-en-tiny` is marked as broken because its
archive is missing.
In a9bf124 (PR #273232) winePackages.staging was upgraded from 8.20 to
9.0-rc1 after which WinBox refuses to run
This change downgrades wine to the stable release (8.20)
We have packages that use `meta.platforms = []` as a sort of synonym
for `broken = true`. Without this commit, the attrnames for those
jobs will end up in the list of attrnames which are expected to
build, even though they are not expected to build.
This file walks the entire nixpkgs tree and emits a superset of all
release attrnames in only 44 seconds on a 3ghz CPU, using 5 gbytes
of memory. By comparison, on the same CPU the `nix-env` hack used
by ofborg on every PR submission requires 41 *minutes* and peaks at
60 gbytes, even with checkMeta turned off. Full details below.
This is:
- 46x faster (or 2.1% of the elapsed time)
- 12.5x less memory (or 8.0% of the peak memory usage)
In order to replace the ofborg check, this list of attrnames must
then be post-filtered for platform-relevance. However, crucially,
the post-filtering can be done *in parallel* on multiple cores by
splitting the attrname list in to chunks. Generating the list of
attrnames cannot be parallelized because it is a single-threaded
cppnix task.
This PR also adds `recurseForDerivations` where necessary within
nixpkgs in order to make this possible -- it screens out various
non-tryEval-catchable failures and infinite recursions. Before
undraftifying, I will add an invocation of this command to the CI
tests, to ensure that the work performed here is not immediately
undone. My next PR will then add an additional CI check confirming
that the emitted attrpaths are in fact a superset of the release
attrpaths calculated by the slow-memory-hog ofborg method.
I have manually confirmed that this is the case at the tip commit of
this PR, but we need CI to make sure this remains true until ofborg
switches to this more-efficient method of calculation; at that point
the superset-check can be dropped.
