The end-to-end tests that check whether `pip_library` correctly applies the `py:zip-unsafe` label to a zip-unsafe target depend on two third-party Python modules, PyYAML and grpcio. The pre-built wheels on PyPI are architecture-specific, so their versions have to be kept in line with ones for which pre-built wheels are available on PyPI (otherwise pip will take > 10 minutes and a lot of resources to build them from source); even when a pre-built wheel is available for the SOABI in question, the download is disproportionately large for such a simple test (7-12MB for grpcio, depending on the SOABI). Replace the `pip_library` zip safety tests with a single, fully self-contained e2e test that occurs within an e2e-specific Please repo, requiring no downloads from PyPI.

The Python 3.14/stable please_pex test is several orders of magnitude faster now, which was the impetus for making this change - previously this test would take over 10 minutes to execute and would occasionally time out while pip built grpcio from source. |
