## Summary
Before:
```console
$ cargo run -- --version
uv 0.5.7 (b17902da0 2024-12-09)
```
After:
```console
$ cargo run -- --version
uv 0.5.7+14 (7cd0ab77a 2024-12-09)
```
Currently `cargo run -- --version` does not includes the number of
commits since last tag, because `cargo-dist` create non-annotated tag,
and
`git log -1 --date=short --abbrev=9 --format='%H %h %cd %(describe)'`
use only annoated tags by default.
```console
$ git log -1 --date=short --abbrev=9 --format='%H %h %cd %(describe)'
7cd0ab77a97cd0ab77a 2024-12-09
```
To include these tags, use `git log -1 --date=short --abbrev=9
--format='%H %h %cd %(describe:tags)'`, which will display:
```console
$ git log -1 --date=short --abbrev=9 --format='%H %h %cd %(describe:tags)'
7cd0ab77a97cd0ab77a 2024-12-09 0.5.7-14-g7cd0ab77a
```
## Summary
Sort of ridiculous, but today this passes, when it should fail:
```toml
[project]
name = "foo"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.13.0"
dependencies = []
[project.optional-dependencies]
async = [
"foo[async]==0.2.0",
]
```
## Summary
In the end, the problem is that `relative_to` has incorrect behavior if
either path is non-normalize (e.g., `foo/bar/../project`). So I've fixed
that method, but we _also_ now normalize `project` upfront, which _also_
fixes the issue.
Closes https://github.com/astral-sh/uv/issues/9692.
## Summary
Small thing I noticed while working on another change: if we error when
extracting `requires-dist`, we go through the full metadata build. We
need to distinguish between fatal errors and "the data isn't static".
## Summary
This is an alternative to #9344. If accepted, I need to audit the
codebase and call sites to apply it everywhere, but the basic idea is:
rather than encoding mutually-incompatible pairs of markers in the
representation itself, we have an additional method on `MarkerTree` that
expands the false-y definition to take into account assumptions about
which markers can be true alongside others. We then check if the the
current marker implies that at least one of them is true.
So, for example, we know that `sys_platform == 'win32'` and
`platform_system == 'Darwin'` are mutually exclusive. When given a
marker expression like `python_version >= '3.7'`, we test if
`python_version >= '3.7'` and `sys_platform != 'win32' or
platform_system != 'Darwin'` are disjoint, i.e., if the following can't
be satisfied:
```
python_version >= '3.7' and (sys_platform != 'win32' or platform_system != 'Darwin')
```
Since, if this can't be satisfied, it implies that the left-hand
expression requires `sys_platform == 'win32'` and `platform_system ==
'Darwin'` to be true at the same time.
I think the main downsides here are:
1. We can't _simplify_ markers based on these implications. So we'd
still write markers like `sys_platform == 'win32' and platform_system !=
'Darwin'`, even though we know the latter expression is redundant.
2. It might be expensive? I'm not sure. I don't think we test for
falseness _that_ often though.
Closes#7760.
Closes#9275.
See #9686

Instead of modifying the error to replace a dummy derivation chain from
construction with the real one, build the error with the real derivation
chain directly.
This came up when trying to improve the build error reporting.
Introduces `DistErrorKind` to avoid error variants for each case that
are only different in one line of the message.
Add a preview option `uv init --build-backend uv --preview` that uses
the uv build backend when generating the project. The uv build backend
is in preview, so the option is also guarded by preview and hidden from
the help message and docs.
For https://github.com/astral-sh/uv/issues/3957#issuecomment-2518757563
In https://github.com/astral-sh/uv/issues/8155#issuecomment-2508969900,
resolution lowest was complaining about missing lower bounds for a
pacakge, even though the package had a URL, too:
```
uv pip install dist/pymatgen-2024.10.3.tar.gz pymatgen[ci,optional] --resolution=lowest
```
The error was raised from `pymatgen[ci,optional]`, because we were
looking at it before looking at the "URL"
`dist/pymatgen-2024.10.3.tar.gz`.
I've also added constraints and overrides to the bounds lookup, since
they are missing from the dependency graph.
Fixes#8155 (again)
## Summary
Closes#9643.
I modified the `commit` fn so this applies to `uv compile --output-file`
too. But I can move it to the export module if we want to restrict this
to `uv export` only.
## Test Plan
`cargo test`
This is like #9556, but at the level of all other builds, including the
resolver and installer. Going through PEP 517 to build a package is
slow, so when building a package with the uv build backend, we can call
into the uv build backend directly instead: No temporary virtual env, no
temp venv sync, no python subprocess calls, no uv subprocess calls.
This fast path is gated through preview. Since the uv wheel is not
available at test time, I've manually confirmed the feature by comparing
`uv venv && cargo run pip install . -v --preview --reinstall .` and `uv
venv && cargo run pip install . -v --reinstall .`. When hacking the
preview so that the python uv build backend works without the setting
the direct build also (wheel built with `maturin build --profile
profiling`), we can see the perfomance difference:
```
$ hyperfine --prepare "uv venv" --warmup 3 \
"UV_PREVIEW=1 target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --preview" \
"target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --find-links target/wheels/"
Benchmark 1: UV_PREVIEW=1 target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --preview
Time (mean ± σ): 33.1 ms ± 2.5 ms [User: 25.7 ms, System: 13.0 ms]
Range (min … max): 29.8 ms … 47.3 ms 73 runs
Benchmark 2: target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --find-links target/wheels/
Time (mean ± σ): 115.1 ms ± 4.3 ms [User: 54.0 ms, System: 27.0 ms]
Range (min … max): 109.2 ms … 123.8 ms 25 runs
Summary
UV_PREVIEW=1 target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --preview ran
3.48 ± 0.29 times faster than target/profiling/uv pip install --no-deps --reinstall scripts/packages/built-by-uv --find-links target/wheels/
```
Do we need a global option to disable the fast path? There is one for
`uv build` because `--force-pep517` moves `uv build` much closer to a
`pip install` from source that a user of a library would experience (See
discussion at #9610), but uv overall doesn't really make guarantees
around the build env of dependencies, so I consider the direct build a
valid option.
Best reviewed commit-by-commit, only the last commit is the actual
implementation, while the preview mode introduction is just a
refactoring touching too many files.
When building a wheel from a source distribution or both a source
distribution and a wheel, the versions in their filenames must be the
same.
By inspecting the filenames, we also assert that the filenames from the
build a valid (we don't enforce normalization though, just that uv can
parse them).
Note that we're not yet checking that also the `pyproject.toml` version,
if declared, and METADATA version matches.
When running `lock_requires_python_exact`, we would download CPython
3.12.0 each time. By instead downloading CPython 3.13.0 ahead of time
and passing it in, we speed the test up and avoid timeouts. Locally in
pycharm, the test goes from 6.5s to 500ms.
When encountering `dynamic = ["version"]` in the pyproject.toml of a
source dist, we can ignore that and treat it as a statically known
metadata distribution, since the filename tells us the version and that
version must not change on build.
This fixed locking PyGObject 3.50.0 from `pygobject-3.50.0.tar.gz`
(minimized):
```toml
[project]
name = "PyGObject"
description = "Python bindings for GObject Introspection"
requires-python = ">=3.9, <4.0"
dependencies = [
"pycairo>=1.16"
]
dynamic = ["version"]
```
Afterwards, `uv add --no-sync toga` passes on Ubuntu 24.04 without the
pygobject build deps, when previously it needed `{ name = "pygobject",
version = "3.50.0", requires-dist = [], requires-python = ">=3.9" }`.
I've added a check that source distribution versions are respected after
build.
Fixes#9548
Add the `uv build --list`, a "subcommand" to list the files that would
be included when building a distribution. It does not build the
distribution, except when a source dist is required for source dist ->
wheel. This is an important debugging tool for the include and exclude
options: Did i actually include the files I wanted, or am i shipping a
broken distribution? Are there any temporary files I still need to
exclude?
Cargo offers this as `cargo package --list`.
`--list` is preview-exclusive, since it requires the fast path, which I
also put into preview.
Examples:
I'll fix the error handling in a follow-up.
Tagging as enhancement because it changes the stable output slightly
(two lines instead of one).
CC @charliermarsh for uv-wide consistency in the stdout/stderr handling.
## Summary
I added `crates/uv-python/create-mirror.py` to make it easy to download
all the needed files to create a mirror for Python distributions in an
offline environment.
the script also has an option to iterate over the git history of the
`download-metadata.json` to make sure we have all the files needed for
all the uv versions
## Test Plan
```

## Summary
This change introduces the `UV_NO_INSTALLER_METADATA` environment
variable
as a way to opt out of the extra installer metadata files that `uv` is
creating.
This is important to achieve reproducible builds in distribution
packaging, allowing to replace usage of
[installer](https://pypi.org/project/installer) with `uv pip install`.
At the time of writing these files are:
- `uv_cache.json`
Contains timestamps which are non-reproducible.
These hashes also leak in to the `RECORD` file.
- `direct_url.json`
Contains the path to the installed wheel.
While not non-reproducible it's not required for distribution packaging.
- `INSTALLER`
Again, not non-reproducible, but of no value in distribution packaging.
## Test Plan
Automated test added.

## Summary
Today, our dependency group implementation is a little awkward... For
each package `P`, we check if `P` contains dependencies for each enabled
group, then add a dependency on `P` with the group enabled. There are a
few issues here:
1. It's sort of backwards... We add a dependency from the base package
`P` to `P` with the group enabled. Then `P` with the group enabled adds
a dependency on the base package.
2. We can't, e.g., enable different groups for different packages. (We
don't have a way for users to specify this on the CLI, but there's no
reason that it should be _impossible_ in the resolver.)
3. It's inconsistent with how extras work, which leads to confusing
differences in the resolver.
Instead, our internal requirement type can now include dependency
groups, which makes dependency groups look much, much more like extras
in the resolver.
## Summary
Update the docs for the GitLab integration, to make it clear that an
entrypoint has to be specified, when a distroless image is being used.
## Test Plan
Without specifying an entrypoint when using a distroless image:
<img
src=https://github.com/user-attachments/assets/35499bd5-51d8-4016-b1d0-2d56956f82e6
width=500>
_It works if you either specify the entrypoint or if the image used in
not a distroless one._
