Building a PEX for multiple platforms doesn't affect `sys.platform` in `extras_require`

9

I'm trying to build a cross-platform (Mac and Linux) PEX that contains the [`doit` library](https://github.com/pydoit/doit), but it seems as if `pex` is not doing anything to make the target platform...

Handle safe_copy failing to hardlink on Windows due to too many existing links

3

Windows does support hard links, and os.link() supports Windows as of Python 3.2. There is a specific error that can be thrown on Windows when you try to create too...

`--no-pre-install-wheels --requirements-pex .. --layout packed` gives `[Errno 21] Is a directory: '.../.deps/....whl'` errors

3

It seems pex emits "Is a directory" errors referring to wheels for invocations that use all three of `--requirements-pex ... --no-pre-install-wheels --layout packed`. For instance: ```shell curl -OLs https://github.com/pex-tool/pex/releases/download/v2.2.2/pex chmod...

Consider using uv as an optional alternate resolver.

Unlike a `pex3 lock update`, a `pex3 lock sync` can update any characteristic of an existing lock; not just individual top-level requirements. As such, changing options that affect accepted artifact...

Unify CLI options with Pip options when requirements files are parsed.

2

Current requirements file parsing skips over Pip options and just allows them to flow through to Pip. This is fine for cases where we only care about Pip's resolve results,...

Peeled out of https://github.com/pantsbuild/pex/issues/2312#issuecomment-1871722718 Thinking about it an external venv should copy files from the wheel cache instead of hardlinks / symlinks. In my case I use pex to create...

If we can round trip from a downloaded `.whl` to an installed wheel chroot and back with full fidelity, then we can fix a long existing latent bug and improve...

consume packed wheel cache in zipapp creation

25

*Closes #2158.* # Problem *#1675 has another repro.* Generating a `--compress --layout zipapp` (the default) regularly exhibits pathologically slow performance **(46s zip / 1m1s total)** on many real-world inputs (especially...
