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. Additionally, wheel entry points
aren't installed into the venv.

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

Also adds support for wheel entry points in venvs. This is done by
having the repo-phase parse entry_points.txt and defining a target for
each entry point. These targets run during build phase, so are able
to generate platform-specific outputs.

Cross-building with Windows is also added, supporting both Windows
as a target or exec platform to generate outputs for the target
platform.

Fixes #3202

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

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.

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.

1. What problem does that solve / functionality it enable?

Currently the py_console_script_binary is building a full runfiles tree and for the usecase that you are implementing in here - a py_binary is just calling utilities within the same venv that is a little bit too heavy. I want to separate the usecases for py_console_script_binary to be only something where we actually want to build a full separate venv for the said scripts.

2. 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.

It should not affect the external API and I agree, the implementation would be way cleaner as we would only depend on the :pkg py_library or py_whl_library target.

Is this compatible with nix? I remember that /bin/bash should be replaced with /usr/bin/env bash on those setups, so I am wondering if it is similar for sh.

We could just verify this assumption and print warnings or fail.

With this, we may remove the wheel.py file because we have the right fallbacks.
