feat(venv): make wheel scripts runnable in venv by rickeylev · Pull Request #3743 · bazel-contrib/rules_python

rickeylev · 2026-04-27T06:10:05Z

Currently, #!python based scripts in a wheel are put into the venv
as-is, so aren't actually runnable.

To fix, rewrite the scripts to re-exec themselves with the python3
binary in the same directory.

DO NOT MERGE: await #3726

ref https://packaging.python.org/en/latest/specifications/binary-distribution-format/#installing-a-wheel-distribution-1-0-py32-none-any-whl for generic data scheme: these are usually installed to the venv root, but that seems ill-advised. So we install into a data sub-directory of the venv.

…into whl.with.data

Uses os.name to correctly assert the Scripts/ and Include/ directory paths when creating the virtual environment on Windows.

Also add debug info to venvs_site_packages_libs_test to help diagnose Windows CI failures.

…rkspace

…addition These changes seemed to cause many regressions in WORKSPACE mode in CI.

Also revert redundant bazel_skylib additions to example WORKSPACE files.

The original target was intended to be internal-only, so it has been renamed and all references updated. No alias was added as per instructions.

…d because data files are always added

The `whl_from_dir_repo` repository rule previously relied on the Unix `zip` utility to create wheels. Because this command isn't natively available on Windows, any tests that depended on repositories generated by this rule had to be explicitly skipped on Windows hosts. To fix this and expand our test coverage, this adds a native Windows fallback. When running on Windows, the rule now invokes a helper PowerShell script that uses .NET compression APIs to create the archive. This script ensures the resulting wheel remains uncompressed and uses zeroed-out timestamps to match the deterministic behavior of the original `zip -0X` command. With this constraint removed, the Unix-only compatibility flags (`SUPPORTS_BZLMOD_UNIXY`) have been dropped, enabling several namespace package and wheel-related integration tests to finally run on Windows.

Code Review

This pull request ensures that wheel data files (bin, include, and data) are included as dependencies and correctly populated into virtual environments when --venv_site_packages=yes is enabled. It introduces a binary rewriter mechanism to adjust shebangs in wheel-provided scripts to use the venv's interpreter. Feedback identifies several critical issues: the rewriter scripts hardcode the interpreter name as python3, the PowerShell rewriter incorrectly generates POSIX shell wrappers, and the selection logic for the rewriter does not properly account for cross-compilation scenarios. Additionally, hardcoded script generation settings in the wheel installer may limit cross-platform compatibility.

+    if rewriter_file.path.endswith(".ps1"):
+        # powershell.exe is used for broader compatibility
+        # It is installed by default on most Windows versions
+        action_exe = "powershell.exe"
+        action_args.add_all([
+            "-ExecutionPolicy",
+            "Bypass",
+            "-NoProfile",

+        action_exe = ctx.attr._venv_bin_rewriter[DefaultInfo].files_to_run


The rewriter selection is based on the execution platform (cfg = "exec"), but the script it generates must be compatible with the target platform. When cross-compiling (e.g., Linux host to Windows target), the current logic will use the host's rewriter (shell script) to generate a script for the target, which will be incompatible. The rewriter logic should be aware of the target OS and the correct interpreter name (e.g. python.exe vs python3).

Oh neat, it looks like entry points already work? I'm guessing something in whl_library is generating something from the entry points config?

rickeylev · 2026-04-27T07:28:03Z

Hm, after poking around a bit, i'm guessing the entry points stuff is actually relying on repo-phase code generating the scripts. It shouldn't be too hard to replace that with a build-time generation rule.

aignas · 2026-04-27T09:49:08Z

I have actually removed the entry point parsing/generation at head with #3735. If you need the code feel free to restore some of it. Should be easy to do a partial revert and just plumb through the entry point script names to create py_console_script_binary targets for.

aignas · 2026-04-27T09:56:46Z

That said, I was thinking that it would be best to return the console scripts via the PyInfo provider (or some other provider) so that all we have to do in py_console_script_binary is get the file from the provider instead of parsing an entry_points.txt file.

I think it is very doable to also use the same provider to expand the console script template on the fly in the venv.

I just removed the entry points generated

😂 😭 lol, ah, what timing. But yeah, shouldn't be hard to re-add it. All it needs to do is read the entry points config and generate a platform-specific file.

return console scripts on PyInfo or some other provider for py_console_script_binary

Two questions:

What problem does that solve / functionality it enable?
Does it affect the py_console_script_binary API?

For (2), I think we had some hacky label-manipulation in the macro to pick the entry points script? A provider would allow figuring that out at analysis phase instead.
