## Summary
Add a note in the documentation to clarify that `uv.toml` files take
precedence over `[tool.uv]` section in `pyproject.toml`, based on the
warning shown in the CLI:
```console
$ uv version
warning: Found both a `uv.toml` file and a `[tool.uv]` section in an adjacent `pyproject.toml`. The `[tool.uv]` section will be ignored in favor of the `uv.toml` file.
uv 0.4.2 (Homebrew 2024-09-01)
```
## 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
Remainder of file ignored
```
(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;
}
```

When a package is included under a platform-specific marker, we know
that wheels that mismatch this marker can never be installed, so we drop
them from the lockfile.
In transformers, we have:
* `tensorflow-text`: `tensorflow-macos; python_full_version >= '3.13'
and platform_machine == 'arm64' and platform_system == 'Darwin'`
* `tensorflow-macos`: `tensorflow-cpu-aws; (python_full_version < '3.10'
and platform_machine == 'aarch64' and platform_system == 'Linux') or
(python_full_version >= '3.13' and platform_machine == 'aarch64' and
platform_system == 'Linux') or (python_full_version >= '3.13' and
platform_machine == 'arm64' and platform_system == 'Linux')`
* `tensorflow-macos`: `tensorflow-intel; python_full_version >= '3.13'
and platform_system == 'Windows'`
This means that `tensorflow-cpu-aws` and `tensorflow-intel` can never be
installed, and we can drop them from the lockfile.
## Summary
I'm not convinced that the behavior is correct as-implemented. When the
user passes a `--python >=3.8` or we discover a `requires-python` from
the workspace, we're currently writing that request out to
`.python-version`. I would probably rather that we write the resolved
patch version?
Closes https://github.com/astral-sh/uv/issues/6821.
The key change here is to use raw strings so that we don't need to
double-escape things like `\d`. And in particular, we rely on the fact
that `"\n"` and `r"\n"` are precisely equivalent when fed to
`Regex::new` in the `regex` crate.
Previously we were using `[+-~]`, but this includes the full range of
characters from `+` to `~`. Incidentally, this does include `-`. We
instead rewrite this as `[-+~]`, which probably matches the intent.
Unlike the previous update, this message is specifically referring to a
fork's markers inside the resolver. We probably *could* massage the
message to be simplified with respect to requires-python, but it's not
obvious to me that that is the right thing to do.
It is not clear whether this update is correct or not. Moreover, it's
not clear whether the status quo is correct or not. The problem is that
`transformers` is so big that it's very hard to understand what the
right output is without a deeper investigation.
One thing that is interesting is if fork prioritization is removed in
this PR *and* on `main`, then the differences in this ecosystem test go
away.
We've decided for now to move forward with this update even though we're
uncertain because this PR fixes a few outstanding correctness issues.
This update changes the error message to one that is worse than the
status quo, but it is still correct because `datasets >= 2.19` doesn't
actually exist given our `EXCLUDE_NEWER` in tests at present.
The underlying cause here seems to be in how PubGrub deals with
reporting incompatibilities. Namely, when it has `foo < 1` and
`foo >= 1`, it reports an incompatibility immediately before looking for
versions. But when it has `foo < 1` and `foo >= 1 ; marker`, then
because they aren't both pubgrub "packages," it starts requesting
versions first and hits the "not available" error path instead of the
"incompatible" error path.
Since this is more of an underlying issue with how we setup
`PubGrubPackage` and our interaction with pubgrub, we ended up deciding
to move forward here with the regression since this PR is fixing a
correctness issue. In particular, if one changes the `requires-python`
to `>=3.8`, then both `main` and this PR produce similarly bad error
messages.
This commit refactors how deal with `requires-python` so that instead of
simplifying markers of dependencies inside the resolver, we do it at the
edges of our system. When writing markers to output, we simplify when
there's an obvious `requires-python` context. And when reading markers
as input, we complexity markers with the relevant `requires-python`
constraint.
When I first wrote this routine, it was intended to only emit a trace
for the final "unioned" resolution. But we actually moved that semantic
operation to the construction of the resolution *graph*. So there is no
unioned `Resolution` any more.
But this is still useful to see. So I changed this to just emit a trace
of *every* resolution right before constructing the graph.
It might be nice to also emit a trace of the unioned graph too. Or
perhaps we should do that instead if this proves too noisy. (Although
this is only emitted at TRACE level.)
These are regression tests for #6269, #6412 and #6836. In this commit,
their test outputs are all wrong. We'll update these snapshots after
fixing the underlying bug by refactoring how `requires-python`
simplification works.
- Respect `UV_PROJECT_ENVIRONMENT` when in project root
- Add `--no-project` and `--no-workspace` to opt-out of above and
`requires-python` detection
- Rename `[NAME]` to `[PATH]` in CLI
