## Summary
This PR takes a different approach to `--with` for `uv run`. Now,
instead of merging the requirements and re-resolving, we have two
phases: (1) sync the workspace requirements to the workspace
environment; then (2) sync the ephemeral `--with` requirements to an
ephemeral environment. The two environments are then layered by setting
the `PATH` and `PYTHONPATH` variables appropriately.
I think this approach simplifies a few things:
1. Once we have a lockfile, the semantics are much clearer, and we can
actually reuse it for the workspace. If we had to add arbitrary
dependencies via `--with`, then it's not really clear how the lockfile
would/should behave.
2. Caching becomes simpler, because we can just cache the ephemeral
environment based on the requirements.
The current version of this PR loses a few behaviors though that I need
to restore:
- `--python` support -- but I'm not yet sure how this is supposed to
behave within projects? It's also left unclear in `uv sync` and `uv
lock`.
- The "reuse the workspace environment if it already satisfies the
ephemeral requirements" behavior.
Closes#3411.
## Summary
This is universal environment variable used to determine the mac OS
deployment target. We now respect it in `--python-platform` -- so we
default to 12.0, but users can override it as needed.
## Summary
We already _don't_ discover a `pyproject.toml` in `~/.config/uv` -- it
must be `uv.toml`. This PR makes the same change for `--config-file` --
it _has_ to be a `uv.toml`.
I think this is reasonable and more consistent, though I'm not sure. A
`pyproject.toml` "means" something -- it defines a project itself, in
which case we should be using project configuration. But creating a
`pyproject.toml` outside the project and passing it via `--config-file`
seems like an anti-pattern.
## Summary
This PR follows Cargo's strategy for merging configuration, albeit in a
more limited way (we don't support as many configuration locations).
Specifically, we merge the user configuration with the workspace
configuration if both are present. The workspace configuration has
priority, such that we take values from the workspace configuration and
ignore those in the user configuration if both are specified for a given
setting -- with the exception of arrays and maps, which are
concatenated.
For now, if a user provides a configuration file with `--config-file`,
we _don't_ merge in the user settings.
See:
https://doc.rust-lang.org/cargo/reference/config.html#hierarchical-structure.
Closes#3420.
## Summary
This is annoying both locally in CI. If anyone wants to fuss with the
filters to fix it, that's fine too, but IMO it's better to disable than
leave it enabled on macOS for now.
When using `tool.uv.sources`, we warn that requirements have a bound,
i.e. at least a lower version constraint.
When using a library, the symbols you import were introduced in
different versions, creating an implicit lower bound. This warning makes
this explicit. This is crucial to prevent backtracking resolvers from
selecting an ancient versions that is not compatible (or worse, doesn't
build), and a performance optimization on top.
This feature is gated to `tool.uv.sources` (as it should have been to
begin with for #3263/#3443) to not unnecessarily break legacy workflows.
It is also helpful specifically when using a `tool.uv.sources` section
that contains constraints that are not published to pypi, e.g. for
workspace dependencies. We can adjust those later to e.g. not constrain
workspace dependencies with `publish = false`, but i think it's the
right setting to start with.
## Summary
These aren't intended for production use; instead, I'm just trying to
frame out the overall data flows and code-sharing for these commands. We
now have `uv sync` (sync the environment to match the lockfile, without
refreshing or resolving) and `uv lock` (generate the lockfile). Both
_require_ a virtual environment to exist (something we should change).
`uv sync`, `uv run`, and `uv lock` all share code for the underlying
subroutines (resolution and installation), so the commands themselves
are relatively small (~100 lines) and mostly consist of reading
arguments and such.
`uv lock` and `uv sync` don't actually really work yet, because we have
no way to include the project itself in the lockfile (that's a TODO in
the lockfile implementation).
Closes https://github.com/astral-sh/uv/issues/3432.
We would previously show the parsed version when erroring due to
trailing content after a valid version, which can look different than
the input. E.g. when encountering `0.1-bulbasaur`, we would display:
```
after parsing '0.1b0', found 'ulbasaur', which is not part of a valid version
```
With storing the input string instead of the input version, we now show:
```
after parsing '0.1-b', found 'ulbasaur', which is not part of a valid version
```
It turns out setuptools often uses Metadata-Version 2.1 in their
PKG-INFO:
4e766834d7/setuptools/dist.py (L64)
`Metadata23` requires Metadata-Version of at least 2.2.
This means that uv doesn't actually recognise legacy editable
installations from the most common way you'd actually get legacy
editable installations (works great for most legacy editables I make at
work though!)
Anyway, over here we only need the version and don't care about anything
else. Rather than make a `Metadata21`, I just add a version field to
`Metadata10`. The one slightly tricky thing is that only
Metadata-Version 1.2 and greater guarantee that the [version number is
PEP 440 compatible](https://peps.python.org/pep-0345/#version), so I
store the version in `Metadata10` as a `String` and only parse to
`Version` at time of use.
Also did you know that back in 2004, paramiko had a pokemon based
versioning system?
Pubgrub got a new feature where all unavailability is a custom, instead
of the reasonless `UnavailableDependencies` and our custom `String` type
previously (https://github.com/pubgrub-rs/pubgrub/pull/208). This PR
introduces a `UnavailableReason` that tracks either an entire version
being unusable, or a specific version. The error messages now also track
this difference properly.
The pubgrub commit is our main rebased onto the merged
https://github.com/pubgrub-rs/pubgrub/pull/208, i'll push
`konsti/main-rebase-generic-reason` to `main` after checking for rebase
problems.
## Summary
It's not clear to me that this should exist at all, but it's causing
errors in projects that don't use `tool.uv.sources`, so we should
definitely remove it for now.
## Summary
We already have a global `--isolated`, which means "ignore any on-disk
configuration". I think we should reuse this for the "ignore the
workspace" setting in `uv run`, rather than `--no-workspace`.
I've also merged the existing `--isolated` and `--no-workspace`
behaviors in `uv run` into a single flag. We may not need separate flags
for this, since the current intent seems to be "ignore the workspace
environment"? Though we could always re-add later.
Closes https://github.com/astral-sh/uv/issues/3421.
Resolves [#3419](https://github.com/astral-sh/uv/issues/3419)
## Summary
Add compatargs to pip install command and hint the user to create a venv
for --user arg.
## Test Plan
Tested it locally.
```bash
cargo run pip install --user flask
Compiling uv v0.1.39 (/home/ahmedilyas/uv/crates/uv)
Finished `dev` profile [unoptimized + debuginfo] target(s) in 8.96s
Running `target/debug/uv pip install --user flask`
error: pip install's `--user` is unsupported (use a virtual environment instead).
```
This change allows switching out the url type for requirements. The
original idea was to allow different types for different requirement
origins, so that core metadata reads can ban non-pep 508 requirements
while we only allow them for requirements.txt. This didn't work out
because we expect `&Requirement`s from all sources to match.
I also tried to split `pep508_rs` into a PEP 508 compliant crate and
into our extensions, but they are to tightly coupled.
I think this change is an improvement still as it reduces the hardcoded
dependence on `VerbatimUrl`.
We now correctly emit relative paths in `uv pip compile` with
`tool.uv.sources` path inputs.
`tool.uv.sources` is mainly intended to be used with the uv lock file
over requirements.txt, but it's good to have basic `uv pip` support
working.
Fixes#3366
## Summary
All of the resolver code is run on the main thread, so a lot of the
`Send` bounds and uses of `DashMap` and `Arc` are unnecessary. We could
also switch to using single-threaded versions of `Mutex` and `Notify` in
some places, but there isn't really a crate that provides those I would
be comfortable with using.
The `Arc` in `OnceMap` can't easily be removed because of the uv-auth
code which uses the
[reqwest-middleware](https://docs.rs/reqwest-middleware/latest/reqwest_middleware/trait.Middleware.html)
crate, that seems to adds unnecessary `Send` bounds because of
`async-trait`. We could duplicate the code and create a `OnceMapLocal`
variant, but I don't feel that's worth it.
## Summary
Users often find themselves dropped into environments that contain
`.egg-info` packages. While we won't support installing these, it's not
hard to support identifying them (e.g., in `pip freeze`) and
_uninstalling_ them.
Closes https://github.com/astral-sh/uv/issues/2841.
Closes#2928.
Closes#3341.
## Test Plan
Ran `cargo run pip freeze --python
/opt/homebrew/Caskroom/miniforge/base/envs/TEST/bin/python`, with an
environment that includes `pip` as an `.egg-info`
(`/opt/homebrew/Caskroom/miniforge/base/envs/TEST/lib/python3.12/site-packages/pip-24.0-py3.12.egg-info`):
```
cffi @ file:///Users/runner/miniforge3/conda-bld/cffi_1696001825047/work
pip==24.0
pycparser @ file:///home/conda/feedstock_root/build_artifacts/pycparser_1711811537435/work
setuptools==69.5.1
wheel==0.43.0
```
Then ran `cargo run pip uninstall`, verified that `pip` was uninstalled,
and no longer listed in `pip freeze`.
Fixes#3371
It seems like uv doesn't proactively enforce 3.8+ and in most cases just
issues a warning. This PR keeps that property, only adding the new check
when it is known to fail. I checked the imports in this file and the
other ones seem fine.
## Summary
Refreshes some of the activation scripts, and fixes some bugs in
`activate_this.py` that were likely the rest of some erroneous
copy-pasting.
Closes https://github.com/astral-sh/uv/issues/3346.

Only allow using `tool.uv.sources` with preview mode, the design isn't
finalized yet.
Not sure what to label this, do we want a preview section and label for
the release notes?
## Summary
We need to partition the editable and non-editable requirements. As-is,
`editable = true` requirements were still being installed as
non-editable.
## Summary
We were writing the build dependencies into the `--target` directory,
which both made builds fail and led to them leaking into the user's
directory.
Closes https://github.com/astral-sh/uv/issues/3349.
