## 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:
```

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.

## 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.
## Summary
This PR formalizes some of the concepts we use in the cache for
"pointers to things".
In the wheel cache, we have files like
`annotated_types-0.6.0-py3-none-any.http`. This represents an unzipped
wheel, cached alongside an HTTP caching policy. We now have a struct for
this to encapsulate the logic: `HttpArchivePointer`.
Similarly, we have files like `annotated_types-0.6.0-py3-none-any.rev`.
This represents an unzipped local wheel, alongside with a timestamp. We
now have a struct for this to encapsulate the logic:
`LocalArchivePointer`.
We have similar structs for source distributions too.
## Summary
This PR adds support for hash-checking mode in `pip install` and `pip
sync`. It's a large change, both in terms of the size of the diff and
the modifications in behavior, but it's also one that's hard to merge in
pieces (at least, with any test coverage) since it needs to work
end-to-end to be useful and testable.
Here are some of the most important highlights:
- We store hashes in the cache. Where we previously stored pointers to
unzipped wheels in the `archives` directory, we now store pointers with
a set of known hashes. So every pointer to an unzipped wheel also
includes its known hashes.
- By default, we don't compute any hashes. If the user runs with
`--require-hashes`, and the cache doesn't contain those hashes, we
invalidate the cache, redownload the wheel, and compute the hashes as we
go. For users that don't run with `--require-hashes`, there will be no
change in performance. For users that _do_, the only change will be if
they don't run with `--generate-hashes` -- then they may see some
repeated work between resolution and installation, if they use `pip
compile` then `pip sync`.
- Many of the distribution types now include a `hashes` field, like
`CachedDist` and `LocalWheel`.
- Our behavior is similar to pip, in that we enforce hashes when pulling
any remote distributions, and when pulling from our own cache. Like pip,
though, we _don't_ enforce hashes if a distribution is _already_
installed.
- Hash validity is enforced in a few different places:
1. During resolution, we enforce hash validity based on the hashes
reported by the registry. If we need to access a source distribution,
though, we then enforce hash validity at that point too, prior to
running any untrusted code. (This is enforced in the distribution
database.)
2. In the install plan, we _only_ add cached distributions that have
matching hashes. If a cached distribution is missing any hashes, or the
hashes don't match, we don't return them from the install plan.
3. In the downloader, we _only_ return distributions with matching
hashes.
4. The final combination of "things we install" are: (1) the wheels from
the cache, and (2) the downloaded wheels. So this ensures that we never
install any mismatching distributions.
- Like pip, if `--require-hashes` is provided, we require that _all_
distributions are pinned with either `==` or a direct URL. We also
require that _all_ distributions have hashes.
There are a few notable TODOs:
- We don't support hash-checking mode for unnamed requirements. These
should be _somewhat_ rare, though? Since `pip compile` never outputs
unnamed requirements. I can fix this, it's just some additional work.
- We don't automatically enable `--require-hashes` with a hash exists in
the requirements file. We require `--require-hashes`.
Closes#474.
## Test Plan
I'd like to add some tests for registries that report incorrect hashes,
but otherwise: `cargo test`
## Summary
Right now, we have a `Hashes` representation that looks like:
```rust
/// A dictionary mapping a hash name to a hex encoded digest of the file.
///
/// PEP 691 says multiple hashes can be included and the interpretation is left to the client.
#[derive(Debug, Clone, Eq, PartialEq, Default, Deserialize)]
pub struct Hashes {
pub md5: Option<Box<str>>,
pub sha256: Option<Box<str>>,
pub sha384: Option<Box<str>>,
pub sha512: Option<Box<str>>,
}
```
It stems from the PyPI API, which returns a dictionary of hashes.
We tend to pass these around as a vector of `Vec<Hashes>`. But it's a
bit strange because each entry in that vector could contain multiple
hashes. And it makes it difficult to ask questions like "Is
`sha256:ab21378ca980a8` in the set of hashes"?
This PR instead treats `Hashes` as the PyPI-internal type, and uses a
new `Vec<HashDigest>` everywhere in our own APIs.
## Summary
Right now, the path-based wheel cache just looks at the symlink to the
archives directory, checks the timestamp on it, and continues with that
symlink as long as the timestamp is up-to-date.
The HTTP-based wheel meanwhile, uses an intermediary `.http` file, which
includes the HTTP caching information. The `.http` file's payload is
just a path pointing to an entry in the archives directory.
This PR modifies the path-based codepaths to use a similar cache file,
which stores a timestamp along with a path to the archives directory.
The main advantage here is that we can add other data to this cache file
(namely, hashes in the future).
## Test Plan
Beyond existing tests, I also verified that this doesn't require a
version bump:
```
git checkout main
cargo run pip install ~/Downloads/zeal-0.0.1-py3-none-any.whl --cache-dir baz --reinstall
git checkout charlie/manifest
cargo run pip install ~/Downloads/zeal-0.0.1-py3-none-any.whl --cache-dir baz --reinstall
cargo run pip install ~/Downloads/zeal-0.0.1-py3-none-any.whl --cache-dir baz --reinstall --refresh
```
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
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
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.
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.
## Summary
I tried out `cargo shear` to see if there are any unused dependencies
that `cargo udeps` isn't reporting. It turned out, there are a few. This
PR removes those dependencies.
## Test Plan
`cargo build`
## Summary
This PR attempts to use a similar trick to that we added in
https://github.com/astral-sh/uv/pull/1878, but for post-releases.
In https://github.com/astral-sh/uv/pull/1878, we added a fake "minimum"
version to enable us to treat `< 1.0.0` as _excluding_ pre-releases of
1.0.0.
Today, on `main`, we accept post-releases and local versions in `>
1.0.0`. But per PEP 440, that should _exclude_ post-releases and local
versions, unless the specifier is itself a pre-release, in which case,
pre-releases are allowed (e.g., `> 1.0.0.post0` should allow `>
1.0.0.post1`).
To support this, we add a fake "maximum" version that's greater than all
the post and local releases for a given version. This leverages our last
remaining free bit in the compact representation.
## Summary
This may be required elsewhere, but all the traces in that issue are
related to persisting the temporary directory to our persistent cache,
so lets start there.
See: https://github.com/astral-sh/uv/issues/1491.
## Summary
Internal-only refactor to consolidate multiple codepaths we have for
checking whether a cached or installed entry is up-to-date with a local
requirement.
## Summary
This also preserves the environment variables in the output file, e.g.:
```
Resolved 1 package in 216ms
# This file was autogenerated by uv via the following command:
# uv pip compile requirements.in --emit-index-url
--index-url https://test.pypi.org/${SUFFIX}
requests==2.5.4.1
```
I'm torn on whether that's correct or undesirable here.
Closes#2035.
Address a few pedantic lints
lints are separated into separate commits so they can be reviewed
individually.
I've not added enforcement for any of these lints, but that could be
added if desirable.
## Summary
Instead of looking at _either_ `pyproject.toml` or `setup.py`, we should
just be conservative and take the most-recent timestamp out of
`pyproject.toml`, `setup.py`, and `setup.cfg`. That will help prevent
staleness issues like those described in
https://github.com/astral-sh/uv/issues/1913#issuecomment-1961544084.
## Summary
Even when pre-releases are "allowed", per PEP 440, `pydantic<2.0.0`
should _not_ include pre-releases. This PR modifies the specifier
translation to treat `pydantic<2.0.0` as `pydantic<2.0.0.min0`, where
`min` is an internal-only version segment that's invisible to users.
Closes https://github.com/astral-sh/uv/issues/1641.
## Summary
If a `pyproject.toml` or similar is changed within an editable, we
should avoid passing our audit check (and thus re-install the package).
Closes https://github.com/astral-sh/uv/issues/1913.
A couple moons ago, I introduced an optimization for version comparisons
by devising a format where *most* versions would be represented by a
single `u64`. This in turn meant most comparisons (of which many are
done during resolution) would be extremely cheap.
Unfortunately, when I did that, I screwed up the preservation of
ordering as defined by the [Version Specifiers spec]. I think I messed
it up because I had originally devised the representation so that we
could pack things like `1.2.3.dev1.post5`, but later realized it would
be better to limit ourselves to a single suffix. However, I never
updated the binary encoding to better match "up to 4 release versions
and up to precisely 1 suffix." Because of that, there were cases where
versions weren't ordered correctly. For example, this fixes a bug where
`1.0a2 < 1.0dev2`, even though all dev releases should order before
pre-releases.
We also update a test so that it catches these kinds of bugs in the
future. (By testing all pairs of versions in a sequence instead of just
the adjacent versions.)

## Summary
Some packages encode logic to embed the current commit SHA in the
version tag, when built within a Git repo. This typically results in an
invalid (non-compliant) version. Here's an example from `pylzma`:
ccb0e7cff3/version.py (L45).
This PR adds a phony, empty `.git` to the cache root, to ensure that any
`git` commands fail.
Closes https://github.com/astral-sh/uv/issues/1768.
## Test Plan
- Create a tag on the current commit, like `v0.5.0`.
- Build `pylzma`, using a cache _within_ the repo:
```
rm -rf foo
cargo run venv
cargo run pip install "pylzma @ 10ef072c3c3b9ea77ebe9546499975/pylzma-0.5.0.tar.gz" --verbose --cache-dir bar
```
It's a little picky about the value, but that seems okay.
```
❯ ./target/debug/uv pip install trio
Audited 1 package in 4ms
❯ UV_NO_CACHE=true ./target/debug/uv pip install trio
Audited 1 package in 50ms
```
Closes#1382
First, replace all usages in files in-place. I used my editor for this.
If someone wants to add a one-liner that'd be fun.
Then, update directory and file names:
```
# Run twice for nested directories
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
# Update files
find . -type f -print0 | xargs -0 rename s/puffin/uv/g
```
Then add all the files again
```
# Add all the files again
git add crates
git add python/uv
# This one needs a force-add
git add -f crates/uv-trampoline
```
