## Summary
I noticed in #2769 that I was now stripping `.git` suffixes from Git
URLs after resolving to a precise commit. This PR cleans up the internal
caching to use a better canonical representation: a `RepositoryUrl`
along with a `GitReference`, instead of a `GitUrl` which can contain
non-canonical data. This gives us both better fidelity (preserving the
`.git`, along with any casing that the user provided when defining the
URL) and is overall cleaner and more robust.
## Summary
This PR leverages our lookahead direct URL resolution to significantly
improve the range of Git URLs that we can accept (e.g., if a user
provides the same requirement, once as a direct dependency, and once as
a tag). We did some of this in #2285, but the solution here is more
general and works for arbitrary transitive URLs.
Closes https://github.com/astral-sh/uv/issues/2614.
Originally a regression test for #2779 but we found out that there's
some weird behavior where different `anyio` versions were preferred
based on the platform.
Addresses panic introduced in #2596 and reported in
https://github.com/astral-sh/uv/issues/2763#issuecomment-2030674936
When there are multiple versions of a package available, we remove the
existing packages before installing the resolved version to "fix" the
environment. We must remove all of the package versions and reinstall
because removing _any_ of the package versions could break the others.
Since reinstalls require a pull from the remote, this broke a contract
between the resolver and the planner which must always agree on which
packages should come from the remote. This further demonstrates that we
should be constructing the install plan with more concrete knowledge
from the resolver (i.e. `ResolvedDist` instead of `Requirement`) to
avoid having to manually ensure logic matches.
## Test plan
Fails on `main` with panic succeeds on branch
```
uv venv --seed
source .venv/bin/activate
pip install anyio==3.7.0 --ignore-installed
pip install anyio==4.0.0 --ignore-installed
cargo run -- pip install anyio black -v
```
## Summary
Ensures that if we resolve any distributions before the resolver, we
cache the metadata in-memory.
_Also_ ensures that we lock (important!) when resolving Git
distributions.
## Summary
This fixes a potential bug that revealed itself in
https://github.com/astral-sh/uv/pull/2761. We don't run into this now
because we always use "allowed URLs", stores the "last" compatible URL
in the map. But the use of the "raw" URL (rather than the "canonical"
URL) means that other writers have to follow that same assumption and
iterate over dependencies in-order.
## Summary
This PR would enable us to support transitive URL requirements. The key
idea is to leverage the fact that...
- URL requirements can only come from URL requirements.
- URL requirements identify a _specific_ version, and so don't require
backtracking.
Prior to running the "real" resolver, we recursively resolve any URL
requirements, and collect all the known URLs upfront, then pass those to
the resolver as "lookahead" requirements. This means the resolver knows
upfront that if a given package is included, it _must_ use the provided
URL.
Closes https://github.com/astral-sh/uv/issues/1808.
With this change, all usages of `EXCLUDE_NEWER` are now in command
wrappers, not in the test functions themselves.
For the venv test, i refactored them into the same kind of test context
abstraction that the other test modules have in the second commit.
The third commit makes`"INSTA_FILTERS` "private", removing the last
remaining individual usage.
Pending windows CI 🤞
## Summary
We can access cache from `BuildContext`. This mirrors
`SourceDistCachedBuilder`, which doesn't accept `Cache` as an argument
and always accesses it through `BuildContext`.
## Summary
If the user provides `uv pip install pyproject.toml`, we now prompt them
to confirm that they meant the `pyproject-toml` package (as opposed to
`uv pip install -r pyproject.toml`).
## Summary
We iterate over the project "requirements" directly in a variety of
places. However, it's not always the case that an input "requirement" on
its own will _actually_ be part of the resolution, since we support
"overrides".
Historically, then, overrides haven't worked as expected for _direct_
dependencies (and we have some tests that demonstrate the current,
"wrong" behavior). This is just a bug, but it's not really one that
comes up in practice, since it's rare to apply an override to your _own_
dependency.
However, we're now considering expanding the lookahead concept to
include local transitive dependencies. In this case, it's more and more
important that overrides and constraints are handled consistently.
This PR modifies all the locations in which we iterate over requirements
directly, and modifies them to respect overrides (and constraints, where
necessary).
## Summary
This is a trimmed-down version of
https://github.com/astral-sh/uv/pull/2684 that only applies to local
source trees for now, which enables workspace-like workflows (whereby
local packages can depend on other local packages at arbitrary depth).
Closes#2699.

```
Previously, we did not consider installed distributions as candidates
while performing resolution. Here, we update the resolver to use
installed distributions that satisfy requirements instead of pulling new
distributions from the registry.
The implementation details are as follows:
- We now provide `SitePackages` to the `CandidateSelector`
- If an installed distribution satisfies the requirement, we prefer it
over remote distributions
- We do not want to allow installed distributions in some cases, i.e.,
upgrade and reinstall
- We address this by introducing an `Exclusions` type which tracks
installed packages to ignore during selection
- There's a new `ResolvedDist` wrapper with `Installed(InstalledDist)`
and `Installable(Dist)` variants
- This lets us pass already installed distributions throughout the
resolver
The user-facing behavior is thoroughly covered in the tests, but
briefly:
- Installing a package that depends on an already-installed package
prefers the local version over the index
- Installing a package with a name that matches an already-installed URL
package does not reinstall from the index
- Reinstalling (--reinstall) a package by name _will_ pull from the
index even if an already-installed URL package is present
- To reinstall the URL package, you must specify the URL in the request

It turns out that #2712 did _not_ fix#2711. After I put up #2712, I
started trying to track down the specific change that caused the
failure. I had assumed at first that it was related to one of our `rkyv`
types, but it actually ended up being one of our msgpack caches. I think
the failure mode is still fundamentally the same idea: the cached data
changed in a way that is still valid msgpack, but got interpreted
differently after deserializing.
The specific change that caused this was the [removal of a field] from
our
metadata type.
Ideally we would just undo the change and add the field back. But that
change has already been shipped out to users. So I believe the only
plausible choice at this point is to bump the `built-wheels` cache. This
will unfortunately mean that `uv` will need to re-build wheels.
Fixes#2711
[removal of a field]:
365c292525 (diff-e42586829f9c2cdbb909bedc5cf95691cc415247f2cbc2ebeb80d887020457bbL29)
It seems likely that we forgot to bump the version of the "simple" cache
in the 0.1.25 release. I'm still working on confirming it, but I figured
I'd get this bump up first.
The main problem here is that our "simple" cache is represented by
`rkyv`, and that in turn is tightly coupled to the representation of a
selection of data types in `uv`. Changing those data types without
bumping the cache version can result in cache deserialization errors
like this, or in the worst case, silent logic errors.
One possibility here is that the representation changed in a way that
permitted it to pass `rkyv` validation, but changed how the data itself
is interpreted. Our cache is robust with respect to `rkyv` validation
(if it fails, the cache will invalidate the entry and self-heal), but
being robust to higher level logical errors in interpretation of the
data is a much more significant challenge. Our best bet there is perhaps
some kind of checksum that we could do on top of `rkyv` validation (or
instead of it), and thus convert silent logical changes in how the data
is interpreted into failure modes that we're already robust to.
Fixes#2711
## Summary
This looks like a big change but it really isn't. Rather, I just split
`get_or_build_wheel` into separate `get_wheel` and `build_wheel` methods
internally, which made `get_or_build_wheel_metadata` capable of _not_
relying on `Tags`, which in turn makes it easier for us to use the
`DistributionDatabase` in various places without having it coupled to an
interpreter or environment (something we already did for
`SourceDistributionBuilder`).
## Summary
This PR enables the resolver to "accept" URLs, prereleases, and local
version specifiers for direct dependencies of path dependencies. As a
result, `uv pip install .` and `uv pip install -e .` now behave
identically, in that neither has a restriction on URL dependencies and
the like.
Closes https://github.com/astral-sh/uv/issues/2643.
Closes https://github.com/astral-sh/uv/issues/1853.
## Summary
This PR removes the custom `DistFinder` that we use in `pip sync`. This
originally existed because `VersionMap` wasn't lazy, and so we saved a
lot of time in `DistFinder` by reading distribution data lazily. But
now, AFAICT, there's really no benefit. Maintaining `DistFinder` means
we effectively have to maintain two resolvers, and end up fixing bugs in
`DistFinder` that don't exist in the `Resolver` (like #2688.
Closes#2694.
Closes#2443.
## Test Plan
I ran this benchmark a bunch. It's basically a wash. Sometimes one is
faster than the other.
```
❯ python -m scripts.bench \
--uv-path ./target/release/main \
--uv-path ./target/release/uv \
scripts/requirements/compiled/trio.txt --min-runs 50 --benchmark install-warm --warmup 25
Benchmark 1: ./target/release/main (install-warm)
Time (mean ± σ): 54.0 ms ± 10.6 ms [User: 8.7 ms, System: 98.1 ms]
Range (min … max): 45.5 ms … 94.3 ms 50 runs
Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet PC without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
Benchmark 2: ./target/release/uv (install-warm)
Time (mean ± σ): 50.7 ms ± 9.2 ms [User: 8.7 ms, System: 98.6 ms]
Range (min … max): 44.0 ms … 98.6 ms 50 runs
Warning: The first benchmarking run for this command was significantly slower than the rest (77.6 ms). This could be caused by (filesystem) caches that were not filled until after the first run. You should consider using the '--warmup' option to fill those caches before the actual benchmark. Alternatively, use the '--prepare' option to clear the caches before each timing run.
Summary
'./target/release/uv (install-warm)' ran
1.06 ± 0.29 times faster than './target/release/main (install-warm)'
```
I stumbled across this when writing tests for
`--emit-marker-expressions`. Namely, I observed that in CI, the `tzdata`
dependency of `pendulum` wasn't included in the `requirements.txt`
output on Windows.
@konstin [suggested] that this was a bug, so I've created a test for it.
In particular, it looks like [`tzdata` is an unconditional dependency of
`pendulum`][tzdata-unconditional].
[suggested]:
https://github.com/astral-sh/uv/pull/2651#discussion_r1539722464
[tzdata-unconditional]:

## Summary
In `pip sync`, we weren't properly handling cases in which a package
_only_ existed in `--find-links` (e.g., the user passed `--offline` or
`--no-index`).
I plan to explore removing `Finder` entirely to avoid these mismatch
bugs between `pip sync` and other commands, but this is fine for now.
Closes https://github.com/astral-sh/uv/issues/2688.
## Test Plan
`cargo test`
Unfortunately these tests are all gated on specific platforms because
the marker expressions they generate are, by design, platform specific.
I think we'll eventually want to figure out a more robust testing
strategy for multi-platform locking (of which this is just the tiniest
of first steps), but I don't think we really have the infrastructure for
that in place yet. That is, we don't yet have a way of generating a
marker expression _for_ a particular environment instead of just the one
that happens to _be_ the current environment.
When enabled, the marker expression for the pinned requirements
is written as a comment at the top of the output. It is disabled
by default *and* hidden because it's not clear whether 1) this is
useful to end users and 2) is an interface we want to commit to.
However, it is useful to expose it in some way so that it can be
tested.
For $reasons, we'll want to be able to clone a `Manifest` so
that it can be re-used to generate a marker expression.
There is likely a refactoring that could be done to avoid the
cloning, but a `Manifest` is likely to be small in practice, and
we'll only need to clone it once.
These are useful for converting lower level marker values types
to their corresponding values from a marker environment.
We'll use these for generating marker expressions based on both
the dependency graph and the current marker environment.
## Summary
Now that we're resolving metadata more aggressively for local sources,
it's worth doing this. We now pull metadata from the `pyproject.toml`
directly if it's statically-defined.
Closes https://github.com/astral-sh/uv/issues/2629.
The snapshot filtering situation has gotten way out of hand, with each
test hand-rolling it's own filters on top of copied cruft from previous
tests.
I've attempted to address this holistically:
- `TestContext.filters()` has everything you should need
- This was introduced a while ago, but needed a few more filters for it
to be generalized everywhere
- Using `INSTA_FILTERS` is **not recommended** unless you do not want
the context filters
- It is okay to extend these filters for things unrelated to paths
- If you have to write a custom path filter, please highlight it in
review so we can address it in the common module
- `TestContext.site_packages()` gives cross-platform access to the
site-packages directory
- Do not manually construct the path to site-packages from the venv
- Do not turn off tests on Windows because you manually constructed a
Unix path to site-packages
- `TestContext.workspace_root` gives access to uv's repository directory
- Use this for installing from `scripts/packages/`
- If you need coverage for relative paths, copy the test package into
the `temp_dir` don't change the working directory of the test fixture
There is additional work that can be done here, such as:
- Auditing and removing additional uses of `INSTA_FILTERS`
- Updating manual construction of `Command` instances to use a utility
- The `venv` tests are particularly frightening in their lack of a test
context and could use some love
- Improving the developer experience i.e. apply context filters to
snapshots by default
This is driving me a little crazy and is becoming a larger problem in
#2596 where I need to move more types (like `Upgrade` and `Reinstall`)
into this crate. Anything that's shared across our core resolver,
install, and build crates needs to be defined in this crate to avoid
cyclic dependencies. We've outgrown it being a single file with some
shared traits.
There are no behavioral changes here.
If you pass a `pyproject.toml` that use Hatch's context formatting API,
we currently fail because the dependencies aren't valid under PEP 508.
This PR makes the static metadata parsing a little more relaxed, so that
we appropriately fall back to PEP 517 there.
## Summary
Passing `pyproject.toml` or `setup.py` to `pip uninstall` is a bit
strange, since it will often require running a resolution to resolve the
dependencies (e.g., build the project), which means we also need to
accept `--index-url` and friends.
## Summary
Hatch allows for highly dynamic customization of metadata via hooks. In
such cases, Hatch
can't upload the PEP 517 contract, in that the metadata Hatch would
return by
`prepare_metadata_for_build_wheel` isn't guaranteed to match that of the
built wheel.
Hatch disables `prepare_metadata_for_build_wheel` entirely for pip.
We'll instead disable
it on our end when metadata is defined as "dynamic" in the
pyproject.toml, which should
allow us to leverage the hook in _most_ cases while still avoiding
incorrect metadata for
the remaining cases.
Closes: https://github.com/astral-sh/uv/issues/2130.
## Summary
When a user passes a `pyproject.toml` to `pip compile` (e.g., `uv pip
compile pyproject.toml`), we extract the requirements from the
`pyproject.toml` directly. However... that isn't always possible (as
seen in the linked issues). When it's _not_, we instead need to run the
PEP 517 build hooks to identify the metadata.

## Summary
`uv` was failing to install requirements defined like:
```
file://localhost/Users/crmarsh/Downloads/iniconfig-2.0.0-py3-none-any.whl
```
Closes https://github.com/astral-sh/uv/issues/2652.
While writing tests for a new flag (`--emit-marker-expression`) for `uv
pip compile`, I noticed that one of my test cases (`pendulum 3.0.0`)
was published in Dec 2023. I wanted to include this package in my
tests, but since it comes after our `EXCLUDE_NEWER` constant, it wasn't
visible to `uv`.
In this PR, I chose to resolve this by bumping `EXCLUDE_NEWER` to
`2024-03-25T00:00:00Z`. I also considered a couple other options:
* For a specific test, override and provide a custom `--exclude-newer`
flag. I felt like this would maybe be okay, but we could easily wind
up in a situation where we do this a lot and have a bunch of different
`--exclude-newer` flags in our tests. I'm not sure if this is a huge
problem in practice. Maybe it's fine.
* Find another package (or invent one) with a similarly interesting
configuration. It seemed easier to just bump `EXCLUDE_NEWER`.
The way I did this was to run `cargo insta test` after bumping
`EXCLUDE_NEWER`.
I then reviewed the snapshot diffs, and if they looked reasonable, I
accepted them.
There was only one case where I changed the test to preserve what I
thought it
was trying to test. That's isolated in its own commit.
With https://github.com/pubgrub-rs/pubgrub/pull/190, pubgrub attaches
all types to a dependency provider to reduce the number of generics. We
need a dummy dependency provider now to emulate this. On the plus side,
pep440_rs drops its pubgrub dependency.
This test was introduced in 42973cd9cb. It
looks like it compares some values against some platform specific code
that attempts to find the OS version. But the comparisons made some
assumptions about what kind of data is available. In this commit, we try
to make the test a little more flexible on Linux by not assuming that
`Option` values are `Some`.
## Summary
I don't see a great reason to allow this, and it adds a lot of
complexity, so `pyproject.toml` files are now limited to `pip compile`
and `pip install -r` -- they can't be passed as `-c` or `--override`.
## Summary
Closes Issue:
- https://github.com/astral-sh/uv/issues/2626
## Test Plan
```
cargo run -- pip install -r dev-requirements.txt -r requirements.txt
```
where both requirements files have same `--index-url`
We put a `.gitignore` with `*` at the top of our cache. When maturin was
building a source distribution inside the cache, it would walk up the
tree to find a gitignore, see that and ignore all python files. We now
add an (empty) `.git` directory one directory below, in the root of
built-wheels cache. This prevents ignore walking further up (it marks
the top level a git repository).
Deptry (from #2490) is a mid sized rust package with additional python
packages, so instead of using it in the test i've replaced it with a
small (44KB total) reproducer that uses cffi for faster building, the
entire test taking <2s on my machine.
Fixes#2490
## Summary
Ensures that (e.g.) installs from conda-forge, Homebrew, and other
distributions don't expose `uv self update` at all.
We'll still show `uv self update` for `pip install uv`, but it will fail
with a good error. Removing the `uv self update` from `pip`-installed
`uv` is more complicated, since we'd need to build separately for the
installer vs. for PyPI.
Closes#2588.
## Summary
This PR enables the source distribution database to be used with unnamed
requirements (i.e., URLs without a package name). The (significant)
upside here is that we can now use PEP 517 hooks to resolve unnamed
requirement metadata _and_ reuse any computation in the cache.
The changes to `crates/uv-distribution/src/source/mod.rs` are quite
extensive, but mostly mechanical. The core idea is that we introduce a
new `BuildableSource` abstraction, which can either be a distribution,
or an unnamed URL:
```rust
/// A reference to a source that can be built into a built distribution.
///
/// This can either be a distribution (e.g., a package on a registry) or a direct URL.
///
/// Distributions can _also_ point to URLs in lieu of a registry; however, the primary distinction
/// here is that a distribution will always include a package name, while a URL will not.
#[derive(Debug, Clone, Copy)]
pub enum BuildableSource<'a> {
Dist(&'a SourceDist),
Url(SourceUrl<'a>),
}
```
All the methods on the source distribution database now accept
`BuildableSource`. `BuildableSource` has a `name()` method, but it
returns `Option<&PackageName>`, and everything is required to work with
and without a package name.
The main drawback of this approach (which isn't a terrible one) is that
we can no longer include the package name in the cache. (We do continue
to use the package name for registry-based distributions, since those
always have a name.). The package name was included in the cache route
for two reasons: (1) it's nice for debugging; and (2) we use it to power
`uv cache clean flask`, to identify the entries that are relevant for
Flask.
To solve this, I changed the `uv cache clean` code to look one level
deeper. So, when we want to determine whether to remove the cache entry
for a given URL, we now look into the directory to see if there are any
wheels that match the package name. This isn't as nice, but it does work
(and we have test coverage for it -- all passing).
I also considered removing the package name from the cache routes for
non-registry _wheels_, for consistency... But, it would require a cache
bump, and it didn't feel important enough to merit that.
## Summary
Detects unused cache entries, which can come in a few forms:
1. Directories that are out-dated via our versioning scheme.
2. Old source distribution builds (i.e., we have a more recent version).
3. Old wheels (stored in `archive-v0`, but not symlinked-to from
anywhere in the cache).
Closes https://github.com/astral-sh/puffin/issues/1059.
Closes#2566
We were storing the username e.g. `charlie@astral.sh` as a
percent-encoded string `charlie%40astral.sh` which resulted in different
headers and broke JFrog's artifactory which apparently does not decode
usernames.
Tested with a JFrog artifactory and AWS CodeArtifact although it is
worth noting that AWS does _not_ have a username with an `@` — it'd be
nice to test another artifactory with percent-encoded characters in the
username and/or password.
## Summary
In `pip uninstall`, we shouldn't need to resolve unnamed requirements,
since we already index packages in `site-packages` by their URL.
This also changes `uninstall` to ignore editables, which matches pip's
behavior.
Part of: https://github.com/astral-sh/uv/issues/313.
## Test Plan
Run `cargo run pip install ./scripts/editable-installs/black_editable`,
followed by each of the following:
- `cargo run pip uninstall ./scripts/editable-installs/black_editable`
- `cargo run pip uninstall black`
- `cargo run pip uninstall ./scripts/editable-installs/black_editable
black`
## Summary
This PR ensures that if a package is already satisfied by the current
environment, we don't bother resolving the named requirement.
Part of: https://github.com/astral-sh/uv/issues/313.
## Test Plan
- `cargo run pip install ./scripts/editable-installs/black_editable`
- `cargo run pip install black --verbose`
## Summary
For example: `cargo run pip install .`
The strategy taken here is to attempt to extract the package name from
the distribution without executing the PEP 517 build steps. We could
choose to do that in the future if this proves lacking, but it adds
complexity.
Part of: https://github.com/astral-sh/uv/issues/313.
## Summary
This PR enables `uv pip install` to accept unnamed requirements, as long
as the requirement ends with the wheel or source distribution archive
name. For example: `cargo run pip install
~/Downloads/anyio-4.3.0.tar.gz`.
In subsequent PRs, I'll expand the scope of supported archives and
patterns.
Part of: https://github.com/astral-sh/uv/issues/313.
## Summary
First piece of https://github.com/astral-sh/uv/issues/313. In order to
support unnamed requirements, we need to be able to parse them in
`requirements-txt`, which in turn means that we need to introduce a new
type that's distinct from `pep508::Requirement`, given that these
_aren't_ PEP 508-compatible requirements.
Part of: https://github.com/astral-sh/uv/issues/313.
Scott schafer got me the idea: We can avoid repeating the path for
workspaces dependencies everywhere if we declare them in the virtual
package once and treat them as workspace dependencies from there on.
It is a common pattern to have an active conda base env (that sets
`CONDA_PREFIX`) and then create a venv on top of that (setting
`VIRTUAL_ENV`).
Previously, we would error when both `VIRTUAL_ENV` and `CONDA_PREFIX`
were set, now `VIRTUAL_ENV` takes precedence over `CONDA_PREFIX`.
Fixes#2028
## Summary
We would like to be able to configure the installer-name so that other
tools can co-exist with `uv`. In `pixi` we would like to use `pixi-uv`
as the installer name, for example, to be able to distinguish them from
packages installed by pure `uv`.
