The failure occurs in the test_pkginfo_to_metadatatest with the following error:
FAILED tests/test_metadata.py::test_pkginfo_to_metadata - assert
[('Metadata-V...win32"'), ...] == [('Metadata-V...win32"'), ...]
At index 3 diff: ('Requires-Dist', 'pip@
https://github.com/pypa/pip/archive/1.3.1.zip')
!= ('Requires-Dist', 'pip @
https://github.com/pypa/pip/archive/1.3.1.zip')
Root cause analysis:
The issue was introduced in wheel version 0.46.3, where the upstream
maintainers modified the test expectations in tests/test_metadata.py.
Specifically, they changed the expected @symbol spacing format:
Upstream change (in wheel 0.46.3):
- ("Requires-Dist", "pip@ https://github.com/pypa/pip/archive/1.3.1.zip";),
+ ("Requires-Dist", "pip @ https://github.com/pypa/pip/archive/1.3.1.zip";),
- ("Requires-Dist", 'foo@ http://host/foo.zip ; sys_platform == "win32"'),
+ ("Requires-Dist", 'foo @ http://host/foo.zip ; sys_platform == "win32"'),
- ("Requires-Dist", 'bar@ http://host/bar.zip ; extra == "extra"'),
+ ("Requires-Dist", 'bar @ http://host/bar.zip ; extra == "extra"'),
However, the actual implementation in wheel/metadata.pystill produces the old
format (pip@ https://...), creating a mismatch between test expectations and
code behavior.
The conflict:
Test expects: "pip @ https://...";(space before @)
Code produces: "pip@ https://...";(space after @)
While we could simply revert the test file to match the implementation, this
would nullify the upstream change without understanding its purpose. The
upstream commit message indicates "Fixed test failures due to metadata
normalization changes," suggesting this change was intentional.
I have already reported this inconsistency to the wheel upstream team
