## Summary
`uv cache prune --ci` will remove the source distribution directory. If
we then need to build a _different_ wheel (e.g., you're building a
package that has Python minor version-specific wheels), we fail, because
we expect the source to be there.
Now, if the source is missing, we re-download it. It would be slightly
easier to just _ignore_ that revision, but that would mean we'd also
lose the already-built wheels -- so if you ran against many Python
versions, we'd continuously lose the cached data.
Closes https://github.com/astral-sh/uv/issues/7543.
## Test Plan
We can add tests, but they _need_ to build non-pure Python wheels, which
tends to be expensive...
For reference:
```console
$ cargo run venv --python 3.12
$ cargo run pip install mercurial==6.8.1 --verbose
$ cargo run cache prune --ci
$ cargo run venv --python 3.11
$ cargo run pip install mercurial==6.8.1 --verbose
```
I also did this with a local `.tar.gz` that I downloaded from PyPI.
## Summary
Both of these can contain rkyv data in their HTTP cache envelopes. As
such, the entries aren't readable by earlier versions of uv, and `uv
cache prune` can break. I should make `uv cache prune` robust to this,
but this feels safest.
Recently, rkyv 0.8 was released. Its API is a fair bit simpler now for
higher level uses (like for us in `uv`) and results in us being able to
delete a fair bit of code. This also removes our last dependency on `syn
1.0`, and thus drops that dependency.
Performance (via testing on the `transformers` example) seems to remain
about the same, which is what was expected:
```
$ hyperfine -w5 -r100 'uv lock' 'uv-ag-rkyv-update lock'
Benchmark 1: uv lock
Time (mean ± σ): 55.6 ms ± 6.4 ms [User: 30.4 ms, System: 35.1 ms]
Range (min … max): 43.0 ms … 73.1 ms 100 runs
Benchmark 2: uv-ag-rkyv-update lock
Time (mean ± σ): 56.5 ms ± 7.2 ms [User: 30.5 ms, System: 36.3 ms]
Range (min … max): 39.1 ms … 71.5 ms 100 runs
Summary
uv lock ran
1.02 ± 0.18 times faster than uv-ag-rkyv-update lock
```
Closes#7415
## Summary
It's very unlikely that retaining these is beneficial, since you tend to
partition the cache by platform anyway.
Closes https://github.com/astral-sh/uv/issues/7394.
## Summary
This PR adds a more flexible cache invalidation abstraction for uv, and
uses that new abstraction to improve support for dynamic metadata.
Specifically, instead of relying solely on a timestamp, we now pass
around a `CacheInfo` struct which (as of now) contains
`Option<Timestamp>` and `Option<Commit>`. The `CacheInfo` is saved in
`dist-info` as `uv_cache.json`, so we can test already-installed
distributions for cache validity (along with testing _cached_
distributions for cache validity).
Beyond the defaults (`pyproject.toml`, `setup.py`, and `setup.cfg`
changes), users can also specify additional cache keys, and it's easy
for us to extend support in the future. Right now, cache keys can either
be instructions to include the current commit (for `setuptools_scm` and
similar) or file paths (for `hatch-requirements-txt` and similar):
```toml
[tool.uv]
cache-keys = [{ file = "requirements.txt" }, { git = true }]
```
This change should be fully backwards compatible.
Closes https://github.com/astral-sh/uv/issues/6964.
Closes https://github.com/astral-sh/uv/issues/6255.
Closes https://github.com/astral-sh/uv/issues/6860.
## 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.
As suggested by @samypr100 on #6680:

## Summary
Instead of using `UV_INTERNAL__TEST_DIR`, it simply exports `TEMP` when
running Windows jobs.
## Test Plan
I'm going to run this manually under ProcMon on my Windows machine and
see where uv writes temp files, hopefully to the dev drive and not
`%(LOCAL)APPDATA%` or something.
I'm going to commit a dummy code change and look at build time changes
in CI.
## Summary
This PR makes `cargo test | windows` faster in CI.
### Before
### After
## Also
This PR disables the `brotli` feature of `async-compression` since it's
not strictly needed, but this has little to do with the improvements
(it's still less code to build).
This PR introduces additional code in uv tool uninstall to ignore errors
(that only seem to happen on ReFS, ie. on Dev Drives) akin to "the thing
we're trying to delete cannot be deleted because it's already being
deleted".
If `raw_os_error` was stable we could do u32 matching instead of that
`.to_string().contains()` abomination.
## Summary
We accidentally changed the Windows cache directory from
`C:\Users\User\AppData\Local\uv\cache` to
`C:\Users\User\AppData\Local\uv` in v0.3.0. We're considering this a
bug, since it does _not_ match the documentation, and prior to v0.3.0,
we always used the former. This PR migrates back to the previous
location. It should be seamless for users, as we move the cache items to
the new location on startup.
Closes https://github.com/astral-sh/uv/issues/6417.
This PR moves us to the Linux strategy for our global directories on
macOS. We both feel on the team _and_ have received feedback (in Issues
and Polls) that the `Application Support` directories are more intended
for GUIs, and CLI tools are correct to respect the XDG variables and use
the same directory paths on Linux and macOS.
Namely, we now use:
- `/Users/crmarsh/.local/share/uv/tools` (for tools)
- `/Users/crmarsh/.local/share/uv/python` (for Pythons)
- `/Users/crmarsh/.cache/uv` (for the cache)
The strategy is such that if the `/Users/crmarsh/Library/Application
Support/uv` already exists, we keep using it -- same goes for
`/Users/crmarsh/Library/Caches/uv`, so **it's entirely backwards
compatible**.
If you want to force a migration to the new schema, you can run:
- `uv cache clean`
- `uv tool uninstall --all`
- `uv python uninstall --all`
Which will clean up the macOS-specific directories, paving the way for
the above paths. In other words, once you run those commands, subsequent
`uv` operations will automatically use the `~/.cache` and `~/.local`
variants.
Closes https://github.com/astral-sh/uv/issues/4411.

## Summary
Passing `--upgrade` to `tool run` is confusing, because it doesn't
upgrade the installed tool. It just causes us to use an isolated tool
environment, which seems wrong.
## Summary
This PR adds a `DistExtension` field to some of our distribution types,
which requires that we validate that the file type is known and
supported when parsing (rather than when attempting to unzip). It
removes a bunch of extension parsing from the code too, in favor of
doing it once upfront.
Closes https://github.com/astral-sh/uv/issues/5858.
## Summary
I think this seems reasonable... Otherwise, we might not go back to PyPI
to revalidate the list of available versions despite the user passing
`--upgrade`.
The comment in the code explains the bulk of this:
```rust
// We previously computed this heuristic freshness lifetime by
// looking at the difference between the last modified header and
// the response's date header. We then asserted that the cached
// response ought to be "fresh" for 10% of that interval.
//
// It turns out that this can result in very long freshness
// lifetimes[1] that lead to uv caching too aggressively.
//
// Since PyPI sets a max-age of 600 seconds and since we're
// principally just interacting with Python package indices here,
// we just assume a freshness lifetime equal to what PyPI has.
//
// Note though that a better solution here is for the index to
// support proper HTTP caching headers (ideally Cache-Control, but
// Expires also works too, as above).
```
We also remove the `heuristic_percent` field on `CacheConfig`. Since
that's actually part of the cache itself, we bump the simple cache
version.
Finally, we add some more `trace!` calls that should hopefully make
diagnosing issues related to the freshness lifetime a bit easier in the
future.
Fixes#5351
## Summary
If you have an executable path on a network share path (like
`\\some-host\some-share\...\python.exe`), canonicalizing it adds the
`\\?` prefix, but dunce cannot safely strip it.
This PR changes the Windows logic to avoid canonicalizing altogether. We
don't really expect symlinks on Windows, so it seems unimportant to
resolve them.
Closes: https://github.com/astral-sh/uv/issues/5440.
## Summary
Users can now run `uv cache prune --ci` (open to feedback on the name of
that flag) to remove all pre-built wheels from the cache, leaving behind
zipped, built wheels (which tend to be the most expensive assets to
re-create). This should greatly increase cache performance in CI
environments, since uploading unzipped wheels can actually hurt
performance if you're persisting the uv cache.
Closes https://github.com/astral-sh/uv/issues/5282.
This name should lead to less confusion. Unfortunately this is a
"breaking cache change" so everyone's cache will be invalidated. I'm not
sure if we should support a rename-on-upgrade.
edit: We can make the breaking change next time we bump the version
## Summary
The basic strategy:
- When the user does `uv tool run`, we resolve the `from` and `with`
requirements (always).
- After resolving, we generate a hash of the requirements. For now, I'm
just converting to a lockfile and hashing _that_, but that's an
implementation detail.
- Once we have a hash, we _also_ hash the interpreter.
- We then store environments in
`${CACHE_DIR}/${INTERPRETER_HASH}/${RESOLUTION_HASH}`.
Some consequences:
- We cache based on the interpreter, so if you request a different
Python, we'll create a new environment (even if they're compatible).
This has the nice side-effect of ensuring that we don't use environments
for interpreters that were later deleted.
- We cache the `from` and `with` together. In practice, we may want to
cache them separately, then layer them? But this is also an
implementation detail that we could change later.
- Because we use the lockfile as the cache key, we will invalidate the
cache when the format changes. That seems ok, but we could improve it in
the future by generating a stable hash from a lockfile that's
independent of the schema.
Closes https://github.com/astral-sh/uv/issues/4752.
## Summary
The build tags in this case are like, e.g., `202206090410`. That's
larger than a `u32`, so we're rejecting the wheel. In theory build tags
could be even larger, but we already use `u64` for version segment so I
think it's fine to keep that constraint here.
I'm going to look into surfacing these errors separately.
Closes https://github.com/astral-sh/uv/issues/4252.
## Test Plan
`cargo run pip install monailabel`
## Summary
We may choose to persist these eventually, but for now, it's useful to
have them colocated with the cache, and in their own dedicated bucket
(so, at the very least, we can keep track of the use-cases).
Closes https://github.com/astral-sh/uv/issues/4219.
## Summary
There are a few behavior changes in here:
- We now enforce `--require-hashes` for editables, like pip. So if you
use `--require-hashes` with an editable requirement, we'll reject it. I
could change this if it seems off.
- We now treat source tree requirements, editable or not (e.g., both `-e
./black` and `./black`) as if `--refresh` is always enabled. This
doesn't mean that we _always_ rebuild them; but if you pass
`--reinstall`, then yes, we always rebuild them. I think this is an
improvement and is close to how editables work today.
Closes#3844.
Closes#2695.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
It removes the unused result when creating the Cache with the
`from_path` constructor. I don't believe it does any io operations any
more at least.
## Summary
It turns out that in the
[spec](https://packaging.python.org/en/latest/specifications/binary-distribution-format/#file-name-convention),
if a wheel filename includes a build tag, then we need to use it to
break ties. This PR implements that behavior. (Previously, we dropped
the build tag entirely.)
Closes#3779.
## Test Plan
Run: `cargo run pip install -i https://pypi.anaconda.org/intel/simple
mkl_fft==1.3.8 --python-platform linux --python-version 3.10`. This now
resolves without error. Previously, we selected build tag 63 of
`mkl_fft==1.3.8`, which led to an incompatibility with NumPy. Now, we
select build tag 70.
## Summary
I don't love this, but it turns out that setuptools is not robust to
parallel builds: https://github.com/pypa/setuptools/issues/3119. As a
result, if you run uv from multiple processes, and they each attempt to
build the same source distribution, you can hit failures.
This PR applies an advisory lock to the source distribution directory.
We apply it unconditionally, even if we ultimately find something in the
cache and _don't_ do a build, which helps ensure that we only build the
distribution once (and wait for that build to complete) rather than
kicking off builds from each thread.
Closes https://github.com/astral-sh/uv/issues/3512.
## Test Plan
Ran:
```sh
#!/bin/bash
make_venv(){
target/debug/uv venv $1
source $1/bin/activate
target/debug/uv pip install opentracing --no-deps --verbose
}
for i in {1..8}
do
make_venv ./$1/$i &
done
```
## Summary
I think this is overall good change because it explicitly encodes (in
the type system) something that was previously implicit. I'm not a huge
fan of the names here, open to input.
It covers some of https://github.com/astral-sh/uv/issues/3506 but I
don't think it _closes_ it.
## Summary
If you run the script included in the linked issue, then `uv cache
clean`, we hit permissions errors on certain directories created by
`setuptools`. The permissions on those directories look like:
```
❯ sudo ls -l /Users/crmarsh/Library/Caches/uv/built-wheels-v3/pypi/opentracing/2.4.0/M-fYsaHAaQQvedmPMUl9D/opentracing-2.4.0.tar.gz/build/bdist.macosx-14.2-arm64/wheel/opentracing
Password:
total 0
drwxr-xr-x 3 crmarsh staff 96 May 11 12:51 harness
```
This PR adds logic to make those directories readable by the current
user.
Closes https://github.com/astral-sh/uv/issues/3515.
When running
```
set UV_CACHE_DIR=%LOCALAPPDATA%\uv\cache-foo && uv venv venv
```
in windows CMD, the error would be just
```
error: The system cannot find the path specified. (os error 3)
```
The problem is that the first action in the cache dir is adding the tag,
and the `cachedir` crate is using `std::fs` instead of `fs_err`. I've
copied the two functions we use from the crate and changed the import
from `std::fs` to `fs_err`.
The new error is
```
error: failed to open file `C:\Users\Konstantin\AppData\Local\uv\cache-foo \CACHEDIR.TAG`
Caused by: The system cannot find the path specified. (os error 3)
```
which correctly explains the problem.
Closes#3280
## Summary
This was unintended. We ended up reverting `Option<bool>` everywhere,
but I missed this once since it's in a separate file.
(If you use `Option<bool>`, Clap requires a value, like `--no-cache
true`.)
## Test Plan
`cargo run pip install flask --no-cache`
## Summary
This PR adds the structs and logic necessary to respect settings from
the workspace. It's a ton of code, but it's mostly mechanical. And,
believe it or not, I pulled out a few refactors in advance to trim down
the code and complexity.
The highlights are:
- All CLI arguments are now `Option`, so that we can detect whether they
were provided (i.e., we can't let Clap fill in the defaults).
- We now have a `*Settings` struct for each command, which merges the
CLI and workspace options (e.g., `PipCompileSettings`).
I've only implemented `PipCompileSettings` for now. If approved, I'll
implement the others prior to merging, but it's very mechanical and I
both didn't want to do the conversion prior to receiving feedback _and_
realized it would make the PR harder to review.
freethreaded python reintroduces abiflags since it is incompatible with
regular native modules and abi3.
Tests: None yet! We're lacking cpython 3.13 no-gil builds we can use in
ci.
My test setup:
```
PYTHON_CONFIGURE_OPTS="--enable-shared --disable-gil" pyenv install 3.13.0a5
cargo run -q -- venv -q -p python3.13 .venv3.13 --no-cache-dir && cargo run -q -- pip install -v psutil --no-cache-dir && .venv3.13/bin/python -c "import psutil"
```
Fixes#2429
## Summary
Similar to `Revision`, we now store IDs in the `Archive` entires rather
than absolute paths. This makes the cache robust to moves, etc.
Closes https://github.com/astral-sh/uv/issues/2908.
