Fixes <https://bugs.gnu.org/33046>.
* guix/build-system/python.scm (pypi-uri): Update the host URI to
"files.pythonhosted.org".
* guix/import/pypi.scm (make-pypi-sexp): Preserve the package name case when
the source URL calls for it.
* guix/import/pypi.scm (maybe-inputs): Add INPUT-TYPE argument, and use it.
(test-section?): New predicate.
(parse-requires.txt): Collect the optional test inputs, and return them as the
second element of the returned list.
(parse-wheel-metadata): Likewise.
(guess-requirements): Adapt.
(make-pypi-sexp): Likewise, and include the test inputs requirements as native
inputs in the returned package expression.
* tests/pypi.scm (test-requires.txt): Include a test section in the
test-requires.txt data.
(test-requires.txt-beaker): New variable.
("parse-requires.txt"): Adapt.
("parse-requires.txt - Beaker"): New test.
("parse-wheel-metadata, with extras"): Adapt.
("parse-wheel-metadata, with extras - Jedi"): Adapt.
("pypi->guix-package, no wheel"): Re-indent, and add the expected
native-inputs.
("pypi->guix-package, wheels"): Likewise.
With newer Wheel releases, there is no more metadata.json file; the METADATA
file should be used instead (see: https://github.com/pypa/wheel/issues/195).
This change updates our PyPI importer so that it uses the latter.
* guix/import/pypi.scm (define-module): Remove unnecessary modules and export
the PARSE-WHEEL-METADATA procedure.
(parse-wheel-metadata): Add procedure.
(guess-requirements): Use it.
* tests/pypi.scm (test-metadata): Test it.
This change enables the PyPI importer to look for requirements in a source
archive of a different type than "tar.gz" or "tar.bz2". Also, scan the source
archive to find a requires.txt file.
* guix/import/pypi.scm: (guess-requirements)[tarball-directory]: Remove procedure.
[guess-requirements-from-source]: Use COMRESSED-FILE? to determine if an
archive type is supported, and some file extension logic that chooses either
"tar" or "unzip" as the extractor. Search for the requires.txt file in the
archive instead of using a static, expected location.
(guess-requirements): Rename the TARBALL argument to ARCHIVE, to denote the
archive format is no longer bound specifically to the Tar format.
(compute-inputs): Likewise.
* tests/pypi.scm ("pypi->guix-package, no wheel"): Mock the requires.txt at a
non-standard location.
("pypi->guix-package, no usable requirement file."): New test.
The previous solution was fragile and could leave unwanted characters in a
requirement name, such as '[' or ']'.
Partially fixes <https://bugs.gnu.org/33047>.
* guix/import/pypi.scm (use-modules): Export SPECIFICATION->REQUIREMENT-NAME
(%requirement-name-regexp): New variable.
(clean-requirement): Rename to...
(specification->requirement-name): this, which now uses
%requirement-name-regexp to select the requirement name from the requirement
specification.
(parse-requires.txt): Adapt.
* guix/import/pypi.scm: Export PARSE-REQUIRES.TXT.
(clean-requirement): Move procedure to the top level.
(guess-requirements): Move the READ-REQUIREMENTS procedure to the top level,
and rename it to PARSE-REQUIRES.TXT. Move the CLEAN-REQUIREMENT procedure to
the top level. Move the COMMENT? functions inside the PARSE-REQUIRES.TXT
procedure.
(parse-requires.txt): Add a SECTION-HEADER? predicate, and use it to prevent
parsing optional requirements.
* tests/pypi.scm (test-requires-with-sections): New variable.
("parse-requires.txt, with sections"): New test.
The output of tar when creating archives for the purpose of tests is not
useful, so we mute it.
* tests/pypi.scm ("pypi->guix-package"): Mute the output of tar.
("pypi->guix-package, wheels"): Likewise.
PyPI packages are mandated to have a setup.py file, which contains a listing
of the required dependencies. The setuptools/distutils machinery embed
metadata in the archives they produce, which contains this information. There
is no need nor gain to collect the requirements from a "requirements.txt"
file, as it is not the true record of dependencies for PyPI packages and may
contain extraneous requirements or not exist at all.
* guix/import/pypi.scm (guess-requirements): Update comment.
[guess-requirements-from-source]: Do not attempt to parse the file
requirements.txt. Streamline logic.
* tests/pypi.scm (test-requires.txt): Rename from test-requirements, to hint
at the file being tested.
("pypi->guix-package"): Adapt so that the fake package contains a requires.txt
file rather than a requirements.txt file.
("pypi->guix-package, wheels"): Likewise.
* gnu/packages/make-bootstrap.scm (package-with-relocatable-glibc)[native-inputs]:
Add SEARCH-PATHS to CROSS-GCC, and NATIVE-SEARCH-PATHS to the native GCC.
These workarounds were removed in cf82643647 and
218eb6e611, but were needed for %BOOTSTRAP-TARBALLS.
* gnu/packages/make-bootstrap.scm (%static-inputs)[coreutils, tar]: Add
<#:configure-flags>.
* guix/import/crate.scm (maybe-cargo-inputs): Remove one level of lists.
* guix/import/crate.scm (maybe-cargo-development-inputs): Same.
* tests/crate.scm: (crate->guix-package)[package]<#:arguments>: Remove
one level of list nesting.
