Does uv honor the no-manylinux install flags?

[harmstyler]

PIP honors a flag for disabling the use of manylinux pre-built whl files. When I use uv and the no-manylinux package, my build finishes in seconds (yay), but that makes me think that uv is not building the manylinux whl files itself, as my normal pip install takes an hour.

https://peps.python.org/pep-0600/
https://github.com/asottile-archive/no-manylinux/blob/main/_manylinux.py

What? Why?
The manylinux spec requires compliant packages to vendor binary dependencies inside the wheel that is distributed. Take for example a library which would (prior to manylinux) dynamically link against libssl. As libssl received security patches, the system binaries would received updates from the OS's package manager. The python library which dynamically links would receive these updates for free without need to recompile, reinstall, etc. Under manylinux, libssl is vendored inside the wheel. To receive security updates, you have to wait for the upstream to produce a new wheel and need to know to install a new version of that library. There's almost no visibility about these vendored wheels which makes managing them at scale impossible. As such, some may choose to ignore this standard.

[zanieb]

The relevant section of the PEP is

In addition, we follow previous specifications, and allow for Python distributors to manually override this check by adding a _manylinux module to their standard library. If this package is importable, and if it defines a function called manylinux_compatible, then package installers should call this function, passing in the major version, minor version, and architecture from the manylinux tag, and it will either return a boolean saying whether wheels with the given tag should be considered compatible with the current system, or else None to indicate that the default logic should be used.

As far as I know, we don't support this yet.

[harmstyler]

As far as I know, we don't support this yet.

Thank you for the quick response and confirmation!

[zanieb]

We can consider supporting it!

[zanieb]

Actually, I think I'm wrong — we do have code to check for this

uv/crates/uv-python/python/packaging/_manylinux.py

Lines 181 to 204 in dd7da6a

	def _is_compatible(arch: str, version: _GLibCVersion) -> bool:
	sys_glibc = _get_glibc_version()
	if sys_glibc < version:
	return False
	# Check for presence of _manylinux module.
	try:
	import _manylinux
	except ImportError:
	return True
	if hasattr(_manylinux, "manylinux_compatible"):
	result = _manylinux.manylinux_compatible(version[0], version[1], arch)
	if result is not None:
	return bool(result)
	return True
	if version == _GLibCVersion(2, 5):
	if hasattr(_manylinux, "manylinux1_compatible"):
	return bool(_manylinux.manylinux1_compatible)
	if version == _GLibCVersion(2, 12):
	if hasattr(_manylinux, "manylinux2010_compatible"):
	return bool(_manylinux.manylinux2010_compatible)
	if version == _GLibCVersion(2, 17):
	if hasattr(_manylinux, "manylinux2014_compatible"):
	return bool(_manylinux.manylinux2014_compatible)
	return True

I'm not sure if we're not properly enforcing it. Is it possible you're getting a cached build?

[charliermarsh]

@zanieb -- I think that's pulled in from the vendored packaging code. It doesn't look like we actually call it though.

[zanieb]

Ah we generate the compatible platform tags directly in Rust?

[charliermarsh]

Yeah, we wrote a platform-tags crate. So we probably need to (1) propagate manylinux_compatible back to Interpreter in get_interpreter_info.py, then (2) respect it in platform-tags.

[charliermarsh]

Agree we should support it per the spec though.

[zanieb]

Thanks for investigating.

I ran an install of cryptography as a proof. Feel free to clean up/remove this comment if it muddies it any.

@harmstyler do you happen to know a package that's faster to build than cryptography with this problem? trying to write a test 🌵

actually, nvm seems like cffi would do the trick.

actually 2x, not sure if there's an easy way to test this based on the output 😢

[harmstyler]

Maybe uamqp?

We might just want to write a unit test instead of an integration test. I think we need to test various _manylinux definitions and assert that our platform tag list is correct.

good call - added a unit test 🌵
