## Summary
I think a better tradeoff here is to skip fetching metadata, even though
we can't validate the extras.
It will help with situations like
https://github.com/astral-sh/uv/issues/5073#issuecomment-2334235588 in
which, otherwise, we have to download the wheels twice.
(This is part of #5711)
## Summary
@BurntSushi and I spotted that the `derivative` crate is only used for
one enum in the entire codebase — however, it's a proc macro, and we pay
for the cost of (re)compiling it in many different contexts.
This replaces it with a private `Inner` core which uses the regular std
derive macros — inlining and optimizations should make this equivalent
to the other implementation, and not too hard to maintain hopefully
(versus a manual impl of `PartialEq` and `Hash` which have to be kept in
sync.)
## Test Plan
Trust CI?
This PR revives #6129, but is less bold:
* It doesn't rename anything. (I think the rename is probably right
though.)
* It doesn't change the _default_ `Debug` impl. Instead, it offers this
as a new `MarkerTree::debug_graph` method.
I found this pretty useful for debugging since it gives a display format
that is more faithful to the internal representation of a `MarkerTree`.
So I think it's worth having around. But making it available in `Debug`
is perhaps a bridge too far since it isn't as familiar as the typical
PEP 508 representation and isn't as succinct.
I did consider printing this when using `{:#?}` (i.e., the "alternate"
debug representation), but too many things use that (like `insta` I
think) to make it practical.
Closes#6129
## Summary
This has bothered me for a while and should be fairly impactful for
users. It requires a weird implementation, since the
distribution-building crate depends on the cache, and so the prune
operation can't live in the cache, since it needs to access internals of
the distribution-building crate.
Closes https://github.com/astral-sh/uv/issues/7096.
## Summary
Like `uv sync`, you can omit the current project (`--no-emit-project`),
a specific package (`--no-emit-package`), or the entire workspace
(`--no-emit-workspace`).
Closes https://github.com/astral-sh/uv/issues/6960.
Closes#6995.
Follow-up to #6959 and #6961: Use the reachability computation instead
of `propagate_markers` everywhere.
With `marker_reachability`, we have a function that computes for each
node the markers under which it is (`requirements.txt`, no markers
provided on installation) or can be (`uv.lock`, depending on the markers
provided on installation) included in the installation. Put differently:
If the marker computed by `marker_reachability` is not fulfilled for the
current platform, the package is never required on the current platform.
We compute the markers for each package in the graph, this includes the
virtual extra packages and the base packages. Since we know that each
virtual extra package depends on its base package (`foo[bar]` implied
`foo`), we only retain the base package marker in the `requirements.txt`
graph.
In #6959/#6961 we were only using it for pruning packages in `uv.lock`,
now we're also using it for the markers in `requirements.txt`.
I think this closes#4645, CC @bluss.
## Summary
We need to prioritize hashes for the distribution over hashes for the
related packages.
I think this needs to be redone entirely though. I can see other issues
with the current approach.
Closes https://github.com/astral-sh/uv/issues/7059.
## Summary
With #6917, there are a lot more PyPy downloads in `uv python list
--all-versions`. I find it clearer to have all the CPython downloads
listed, then all the PyPy downloads, rather than interspersing them. But
this is subjective, feel free to push back!
## Summary
This PR adds `--package` support to `uv build`, such that you can use
`--package` from anywhere in a workspace to build any member.
If a source directory is provided, we use that as the workspace root.
If a file is provided, we error.
For now, `uv build` only builds the current package, making it
semantically identical to `uv sync`.
## Summary
This PR allows users to run `uv build --wheel ./path/to/source.tar.gz`
to build a wheel from a source distribution. This is also the default
behavior if you run `uv build ./path/to/source.tar.gz`. If you pass
`--sdist`, we error.
## Summary
This PR exposes uv's PEP 517 implementation via a `uv build` frontend,
such that you can use `uv build` to build source and binary
distributions (i.e., wheels and sdists) from a given directory.
There are some TODOs that I'll tackle in separate PRs:
- [x] Support building a wheel from a source distribution (rather than
from source) (#6898)
- [x] Stream the build output (#6912)
Closes https://github.com/astral-sh/uv/issues/1510
Closes https://github.com/astral-sh/uv/issues/1663.
In the `lock_redact_https` test specifically, it prompts a link mode
warning from `uv` on my system. Debugging seems to suggest it is
provoked by attempting to hardlink between `/tmp` and `~/.local`. Since
these are on different file systems for me (with `/tmp` being a
ramdisk), it provokes the warning, and this turn spoils the snapshot
when running tests locally.
This PR adds a test specific filter rule to fix this.
## Summary
The error handlers now happen one level higher, matching on _any_ `Err`
that's returned from the lock-and-sync operations.
Closes https://github.com/astral-sh/uv/issues/7011.
`_virtualenv.py` doesn't need to import `__future__.annotations`, as it
has none.
Removing the import:
* Restores the action of the VIRTUALENV_PATCH on Python 3.6
* Eliminates 24 lines of error messages displayed by Python 3.6 when it
starts in an environment created by uv:
```plaintext
Error processing line 1 of /tmp/tmp.ENwqZ0oeyb/lib/python3.6/site-packages/_virtualenv.pth:
Traceback (most recent call last):
File "~/.pyenv/versions/3.6.15/lib/python3.6/site.py", line 168, in addpackage

from __future__ import annotations
^
SyntaxError: future feature annotations is not defined

```
(Python displays the errors above twice.)
I appreciate the Python team no longer support Python 3.6, but
RedHat-style Linux distributions will support Python 3.6 in their
`/usr/libexec/platform-python` until [releasever 8 expires in
2029](https://access.redhat.com/support/policy/updates/errata#RHEL8_Planning_Guide).
I'm happy for the community to move on, in general, but don't see the
harm in helping those who can't.
I'm not yet sure what in the “remainder of file ignored” is necessary
for my project's build, as I haven't yet finished digging that from
under Hatch. I'll follow up on #6426 when I do, so we can concentrate on
getting to the happy cow.
## Test Plan
```sh
( set -eu
export VIRTUAL_ENV="$(mktemp -d)"
./target/release/uv venv "$VIRTUAL_ENV" --python=python3.6
./target/release/uv pip install cowsay
$VIRTUAL_ENV/bin/python -m cowsay --text 'Look, a talking cow!' )
```
Happy output:

## Summary
Resolves issues mentioned in comments
* https://github.com/astral-sh/uv/issues/6699#issuecomment-2322515962
* https://github.com/astral-sh/uv/issues/6866#issuecomment-2322785906
Further investigation on the comments revealed that the pointer
arithmethic being performed in `let handle_start = unsafe {
crt_magic.offset(1 + handle_count) };` from [posy
trampoline](dda22e6f90/src/trampolines/windows-trampolines/posy-trampoline/src/bounce.rs (L146))
had some slight errors. Since `crt_magic` was a `*const u32`, doing an
offset by `1 + handle_count` would offset by too much, with some
possible out of bounds reads or attempts to call CloseHandle on garbage.
We needed to offset differently since we want to offset by
`handle_count` bytes after the initial offset as seen in
[launcher.c](888c48b568/PC/launcher.c (L578)).
Similarly, we needed to skip the first 3 handles, otherwise we'd still
be attempting to close standard I/O handles of the parent (in this case
the shell from `busybox.exe sh -l`).
I also added a few extra checks available from `launcher.c` which checks
if the handle value is `-2` just to match the distlib implementation
more closely and minimize differences.
## Test Plan
Manually compiled distlib's launcher with additional logging and
replaced `Lib/site-packages/pip/_vendor/distlib/t64.exe` with the
compiled one to log pointers. As a result, I was able to verify the
retrieved handle memory addresses in this function actually match in
both uv and distlib's implementation from within busybox.exe nested
shell where this behavior can be observed and manually tested.
I was also able to confirm this fixes the issues mentioned in the
comments, at least with busybox's shell, but I assume this would fix the
case with cmake.
## Open areas
`launcher.c` also [checks the
size](888c48b568/PC/launcher.c (L573-L576))
of `cbReserved2` before retrieving `handle_start` which this function
currently doesn't do. If we wanted to, we could add the additional check
here as well, but I wasn't fully sure why it wasn't added in the first
place. Thoughts?
```rust
// Verify the buffer is large enough
if si.cbReserved2 < (size_of::<u32>() as isize + handle_count + size_of::<HANDLE>() as isize * handle_count) as u16 {
return;
}
```
