The build wanted to create a Cargo.lock in the top-level source
directory (presumably because it is also a Cargo project), since we
were crating the lock file in sourceRoot (which was set to the example
project). This failed because the sources are read-only. Change the
test to create the lock file in the top-level crate directory, which
is Cargo's default behavior.
The test builds the PyO3 word_count example module using
maturinBuildHook. The motivation is to have a trivial test that does
not regress for reasons unrelated to maturin or hook updates.
continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
Changes the default fetcher in the Rust Platform to be the newer
`fetchCargoTarball`, and changes every application using the current default to
instead opt out.
This commit does not change any hashes or cause any rebuilds. Once integrated,
we will start deleting the opt-outs and recomputing hashes.
See #79975 for details.
pyo3-pack has been renamed to maturin version 0.7.0. Other larger
changes are:
- Mixed rust/python layout
- Added PEP 517 support
- Support settings all applicable fields from the python core
metadata specification in Cargo.toml
