Not a performance optimization, but the function had become too large.
No logic changes, just code moving around. Looks slightly better when
ignoring whitespace changes.
It's still too complex but i haven't found an apt simplification.
## Summary
This allows, e.g., `uv remove flask[dotenv]` to remove `flask`. Like
`pip install` and `uv pip install`, the content after the package name
has no effect.
Closes https://github.com/astral-sh/uv/issues/9764.

## Summary
https://docs.rs/serde_json/latest/serde_json/fn.from_reader.html
suggests that
> When reading from a source against which short reads are not
efficient, such as a
[File](https://doc.rust-lang.org/std/fs/struct.File.html), you will want
to apply your own buffering because serde_json will not buffer the
input. See
[std::io::BufReader](https://doc.rust-lang.org/std/io/struct.BufReader.html).
Without this buffering, we observe a sequence of single byte reads which
can be quite inefficient depending on the underlying filesystem.
This adds buffering with `std::io::BufReader` to resolve this.

## Summary
When `--upgrade` is provided, we should retain already-installed
packages _if_ they're newer than whatever is available from the
registry.
Closes https://github.com/astral-sh/uv/issues/10089.
## Summary
Sort of undecided on this. These are already stored as `dyn Reporter` in
each struct, so we're already using dynamic dispatch in that sense. But
all the methods take `impl Reporter`. This is sometimes nice (the
callsites are simpler?), but it also means that in practice, you often
_can't_ pass `None` to these methods that accept `Option<impl
Reporter>`, because Rust can't infer the generic type.
Anyway, this adds more consistency and simplifies the setup by using
`Arc<dyn Reporter>` everywhere.

## Summary
This PR extends #10046 to also handle architectures, which allows us to
correctly include `2.5.1` on the `cu124` index for ARM Linux.
Closes https://github.com/astral-sh/uv/issues/9655.
## Summary
This should address the comment here:
https://github.com/astral-sh/uv/pull/10179#issuecomment-2569189265. We
don't compute implied markers if the marker is already `TRUE`, and we
set it to `TRUE` as soon as we see a source distribution. So if we visit
the source distribution before the wheels, we'll avoid computing these
for any irrelevant distributions.
The uv-performance-memory-allocator is currently optimized out at least
on musl due to the crate being otherwise unused
(https://github.com/rust-lang/rust/issues/64402), causing musl to not
use jemalloc and being slow.
Command:
```
cargo build --target x86_64-unknown-linux-musl --profile profiling
hyperfine --warmup 1 --runs 10 --prepare "uv venv -p 3.12" "target/x86_64-unknown-linux-musl/profiling/uv pip compile scripts/requirements/airflow.in"
```
Before:
```
Time (mean ± σ): 1.149 s ± 0.013 s [User: 1.498 s, System: 0.433 s]
Range (min … max): 1.131 s … 1.173 s 10 runs
```
After:
```
Time (mean ± σ): 552.6 ms ± 4.7 ms [User: 771.7 ms, System: 197.5 ms]
Range (min … max): 546.4 ms … 561.6 ms 10 runs
The `cdylib` was used for the pyo3 bindings to uv-pep508, which don't
exist anymore. It was now creating warnings on musl due to musl
(statically linked) no supporting shared libraries.
## Summary
This follows Ruff's design exactly: you can provide a version specifier
(like `>=0.5`), and we'll enforce it at runtime.
Closes https://github.com/astral-sh/uv/issues/8605.
## Summary
Allows uv to recognize the ARMv5TE platform. This platform is currently
supported on Debian distributions. It is an older 32 bit platform mostly
used in embedded devices, currently in rust tier 2.5 so it requires
cross compilation.
Fixes#10157 .
## Test Plan
Tested directly on device by applying a slightly different patch to tag
0.5.4 which is used by the current Home Assistant version (2024.12.5).
After the patch Home Assistant is able to recognize the Python venv and
setup its dependencies.
Patched uv was built with
```
$ CARGO_TARGET_ARMV5TE_UNKNOWN_LINUX_GNUEABI_LINKER="/usr/bin/arm-linux-gnueabi-gcc" maturin build --release --target armv5te-unknown-linux-gnueabi --manylinux off
```
The target wheel was then moved on the device and installed via pip
install.
## Summary
Closes#7913 by adding an optional `--description` argument to `uv init`
that fills the description field in the pyproject.toml with the supplied
arg value.
Updated `uv init` docs to describe this new optional argument.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Added snapshot tests in `uv/crates/uv/tests/it/init.rs` to test this
functionality.
<!-- How was it tested? -->

## Summary
This PR solves an issue on Windows that platform-specific paths are
written to the `RECORD` file when installing, which is inconsistent with
PEP 376, quoting:
> Each record is composed of three elements:
>
>the file’s path
> * a ‘/’-separated path, relative to the base location, if the file is
under the base location.
> * a ‘/’-separated path, relative to the base location, if the file is
under the installation prefix AND if the base location is a subpath of
the installation prefix.
> * an absolute path, using the local platform separator

## Summary
This PR introduces a `LockTarget`, which is peer to `InstallTarget` and
enables us to capture the common functionality necessary to support
locking.
For now, to minimize changes, only the `Workspace` target is
implemented. In a future PR, I'll add a `Script` target for both locking
and installing.
## Summary
The proximate motivation is that I want to add new variant for scripts,
but `uv-resolver` can't depend on `uv-scripts` without creating a
circular dependency. However, I think this _does_ just make more sense
-- the resolver crate shouldn't be coupled to the various kinds of
workspaces, and these details are mostly encoded in `projects/lock.rs`
and similar files.
## Summary
This is necessary for some future improvements to non-`[project]`
workspaces and PEP 723 scripts. It's not "breaking", but it will
invalidate lockfiles for non-`[project]` workspaces. I think that's
okay, since we consider those legacy right now, and they're really rare.
## Summary
We had the right logic for determining whether the list is already
sorted, but we forgot to apply the same logic when deciding where to
insert the requirement, which made the list _unsorted_ for future
operations.
Closes https://github.com/astral-sh/uv/issues/10076.
## Summary
A few places where there are extra conversions to and from string that
seem unnecessary; a few places where we're using `PathBuf` instead of
`PortablePathBuf`.
## Summary
This is yet another variation on
https://github.com/astral-sh/uv/pull/9928, with a few minor changes:
1. It only applies to local versions (e.g., `2.5.1+cpu`).
2. It only _considers_ the non-local version as an alternative (e.g.,
`2.5.1`).
3. It only _considers_ the non-local alternative if it _does_ support
the unsupported platform.
4. Instead of failing, it falls back to using the local version.
So, this is far less strict, and is effectively designed to solve
PyTorch but nothing else. It's also not user-configurable, except by way
of using `environments` to exclude platforms.
## Summary
We had a bug in our handling of escape sequences that caused us to
duplicate backslashes. If you installed repeatedly, we'd keep doubling
them, leading to an exponential blowup.
Closes#10060.
uv gives priorities to packages by package name, not by virtual package
(`PubGrubPackage`). pubgrub otoh when prioritizing order the virtual
packages. When the order of virtual packages changes, uv changes its
resolutions and error messages. This means uv was depending on
implementation details of pubgrub's prioritization caching.
This broke with https://github.com/pubgrub-rs/pubgrub/pull/299, which
added a tiebreaker term that made pubgrub's sorting deterministic given
a deterministic ordering of allocating the packages (which happens the
first time pubgrub sees a package).
The new custom tiebreaker decreases the difference to upstream pubgrub.
Previously, the batch prefetcher was part of the solver loop, used
across forks. This would lead to each preference in a fork being counted
as a tried version, so that after 5 forks with the identical version, we
would start batch prefetching. The reported numbers of tried versions
are also reported. By tracking the batch prefetcher on the fork the
numbers are corrected.
An alternative would be tracking the actually tried versions, but that
would mean more overhead in the top level solver loop when the current
heuristic works.
In `ecosystem/transformers`:
```

Hello! 🙂
## Summary
After submitting retry mechanisms on scripts installation for windows:
#9543 , I noticed that some other functions were using the same
`persist` features of temporary files. This could lead to the same issue
spotted before (temporary lock by AV/EDR software). I validated that it
was possible.
So I updated them to go through the same function on Windows, which is
using the retry mechanisms if needed.
In order to do so, I add to add an async version of the
`persist_with_retry`.
There is a little trick to make the borrow-checker happy line 306,
curious of your opinion on it? This is just a pointer move so it should
not induce some performance regression if I'm not mistaking.
I also updated them to use `fs_err` on Unix for better error messages.
Also, one of the error messages I introduced was badly formatted, I
fixed it. 🙂
## Test Plan
The changes should be iso functional and covered with the existing
test-suite.
## Summary
With the advent of `--fork-strategy requires-python` (the default), we
actually _want_ to solve higher lower-bound forks before lower
lower-bound forks. The former ensures we get the most compatible
versions, while the latter ensures we get fewer overall versions. These
two strategies match up with `--fork-strategy`, but need to be respected
as such.
Closes https://github.com/astral-sh/uv/issues/9998.
From PEP 517:
```python
def prepare_metadata_for_build_wheel(metadata_directory, config_settings=None):
...
```
> Must create a .dist-info directory containing wheel metadata inside
the specified metadata_directory (i.e., creates a directory like
{metadata_directory}/{package}-{version}.dist-info/).
```python
def build_wheel(wheel_directory, config_settings=None, metadata_directory=None):
...
```
> If the build frontend has previously called
prepare_metadata_for_build_wheel and depends on the wheel resulting from
this call to have metadata matching this earlier call, then it should
provide the path to the created .dist-info directory as the
metadata_directory argument.
Notice that the `metadata_directory` is different for the both hooks:
For `prepare_metadata_for_build_wheel` is doesn't contain the
`.dist-info` directory as final segment, for `build_wheel` it does.
Previously, the code assumed that both directories didn't contain the
`.dist-info` for both cases.
Checked with:
```
maturin build
uv init test-uv-build-backend --build-backend uv
cd test-uv-build-backend
uv build --sdist --preview
cd ..
UV_PREVIEW=1 pip install test-uv-build-backend/dist/test_uv_build_backend-0.1.0.tar.gz --no-index --find-links target/wheels/ -v --no-cache-dir

## Summary
Override XDG_CONFIG_DIRS in show_settings tests, in order to ensure that
they don't pick system configuration, and therefore fail due to value
mismatches. This specifically addresses test failures on Gentoo where a
default `/etc/xdg/uv/uv.toml` is installed, and users are free to modify
it.
Prior to #9914, we used to set `XDG_CONFIG_DIRS` locally before running
the test suite. However, since the test now wipes the environment, the
problem can no longer be resolved downstream.
## Test Plan
`cargo test` on a Gentoo system (with `/etc/xdg/uv/uv.toml` present).

## Summary
A revival of an old idea (#9344) that I have slightly more confidence in
now. I abandoned this idea because (1) it couldn't capture that, e.g.,
`platform_system == 'Windows' and sys_platform == 'foo'` (or some other
unknown value) are disjoint, and (2) I thought that Android returned
`"android"` for one of `sys_platform` or `platform_system`, which
would've made this logic incorrect.
However, it looks like Android... doesn't do that? And the values here
are almost always in a small, known set. So in the end, the tradeoffs
here actually seem pretty good.
Vis-a-vis our current solution, this can (e.g.) _simplify out_
expressions like `sys_platform == 'win32' or platform_system ==
'Windows'`.

Since the `backoff` dependency is only *used* on Windows in practice,
this PR would ensure that it is only *compiled* on Windows, too. This is
helpful because it appears to be unmaintained upstream,
https://github.com/astral-sh/uv/issues/10001, and it would be nice to be
able to [drop it from
Fedora](https://bugzilla.redhat.com/show_bug.cgi?id=2329729).

There are two changes here
1. We now exclude pre-releases (if they are not allowed) from the
available versions set when simplifying ranges, this means the
simplified range reflects the _allowed_ available versions — which is
what we want. We no longer segment ranges into arbitrary looking
segments..
2. We improve on #9885, expanding the scope to avoid regressions where
we would now otherwise enumerate a bunch of versions

Build failures are one of the most common user facing failures that
aren't "obivous" errors (such as typos) or resolver errors. Currently,
they show more technical details than being focussed on this being an
error in a subprocess that is either on the side of the package or -
more likely - in the build environment, e.g. the user needs to install a
dev package or their python version is incompatible.
The new error message clearly delineates the part that's important (this
is a build backend problem) from the internals (we called this hook) and
is consistent about which part of the dist building stage failed. We
have to calibrate the exact wording of the error message some more. Most
of the implementation is working around the orphan rule, (this)error
rules and trait rules, so it came out more of a refactoring than
intended.
Example:
Enable `lzma-sys/static` through the performance feature not only in uv,
but in uv-dev and uv-bench too, to avoid the system dependency on
`liblzma-dev`.
Ref #9880
In a message like
```
❯ echo "numpy>2" | uv pip compile -p 3.8 -
× No solution found when resolving dependencies:
╰─▶ Because the requested Python version (>=3.8.0) does not satisfy Python>=3.10 and the requested
Python version (>=3.8.0) does not satisfy Python>=3.9,<3.10, we can conclude that Python>=3.9 is incompatible.
And because numpy>=2.0.1,<=2.0.2 depends on Python>=3.9 and only the following versions of numpy are available:
numpy<=2.0.2
```
I'm surprised that `-p 3.8` leads to expressions like `>=3.8.0` (I
understand it, of course, but it's not intuitive) and then all the
_other_ Python versions in the message omit the trailing zero. This
updates the `PythonRequirement` parsing to drop the trailing zeros. It's
easier to do there because the version is not yet abstracted.
When using a 32-bit OS on 64-bit host, almost all Python std methods
will report a 64-bit aarch64, but we most not install 64-bit executables
since Python is actually 32-bit, identifiable through
`struct.calcsize("P") == 4`.

For publishing, we want to allow all simple `[[tool.uv.index]]` entries,
whether they are explicit or not. We don't allow flat indexes here,
assuming that an index you can upload to has a simple index URL (and
generally doesn't have a flat index URL, at least I don't know any case
that has).
The `no_index` branch isn't used atm, but I left it in case the method
gathers more users.

Background reading: https://github.com/astral-sh/uv/issues/8157
Companion PR: https://github.com/astral-sh/pubgrub/pull/36
Requires for test coverage: https://github.com/astral-sh/packse/pull/230
When two packages A and B conflict, we have the option to choose a lower
version of A, or a lower version of B. Currently, we determine this by
the order we saw a package (assuming equal specificity of the
requirement): If we saw A before B, we pin A until all versions of B are
exhausted. This can lead to undesirable outcomes, from cases where it's
just slow (sentry) to others cases without lower bounds where be
backtrack to a very old version of B. This old version may fail to build
(terminating the resolution), or it's a version so old that it doesn't
depend on A (or the shared conflicting package) anymore - but also is
too old for the user's application (fastapi). #8157 collects such cases,
and the `wrong-backtracking` packse scenario contains a minimized
example.
We try to solve this by tracking which packages are "A"s, culprits, and
"B"s, affected, and manually interfering with project selection and
backtracking. Whenever a version we just chose is rejected, we give the
current package a counter for being affected, and the package it
conflicted with a counter for being a culprit. If a package accumulates
more counts than a threshold, we reprioritize: Undecided after the
culprits, after the affected, after packages that only have a single
version (URLs, `==<version>`). We then ask pubgrub to backtrack just
before the culprit. Due to the changed priorities, we now select package
B, the affected, instead of package A, the culprit.
To do this efficiently, we ask pubgrub for the incompatibility that
caused backtracking, or just the last version to be discarded (due to
its dependencies). For backtracking, we use the last incompatibility
from unit propagation as a heuristic. When a version is discarded
because one of its dependencies conflicts with the partial solution, the
incompatibility tells us the package in the partial solution that
conflicted.
We only backtrack once per package, on the first time it passes the
threshold. This prevents backtracking loops in which we make the same
decisions over and over again. But we also changed the priority, so that
we shouldn't take the same path even after the one time we backtrack (it
would defeat the purpose of this change).
There are some parameters that can be tweaked: Currently, the threshold
is set to 5, which feels not too eager with so me of the conflicts that
we want to tolerate but also changes strategies quickly. The relative
order of the new priorities can also be changed, as for each (A, B) pair
the priority of B is afterwards lower than that for A. Currently,
culprits capture conflict for the whole package, but we could limit that
to a specific version. We could discard conflict counters after
backtracking instead of keeping them eternally as we do now. Note that
we're always taking about pairs (A, B), but in practice we track
individual packages, not pairs.
A case that we wouldn't capture is when B is only introduced to the
dependency graph after A, but I think that would require cyclical
dependency for A and B to conflict? There may also be cases where
looking at the last incompatibility is insufficient.
Another example that we can't repair with prioritization is
urllib3/boto3/botocore: We actually have to check all the newer versions
of boto3 and botocore to identify the version that allows with the older
urllib3, no shortcuts allowed.
```
urllib3<1.25.4
boto3
```
All examples I tested were cases with two packages where we only had to
switch the order, so I've abstracted them into a single packse case.
This PR changes the resolution for certain paths, and there is the risk
for regressions.

## Summary
If the shell is currently in a directory that no longer exists, uv will
panic from any command. Panicking is a confusing behavior to those
unfamiliar with Rust and can sometimes make it hard to determine the
true issue.
Closes#9875
## Test Plan
The reproduction steps in the issue report were followed and uv no
longer panics. `uv version` can still successfully print the version if
the directory does exist.

## Summary
This PR makes the behavior in https://github.com/astral-sh/uv/pull/9827
the default: we try to select the latest supported package version for
each supported Python version, but we still optimize for choosing fewer
versions when stratifying by platform.
However, you can opt out with `--fork-strategy fewest`.
Closes https://github.com/astral-sh/uv/issues/7190.
## Summary
This PR addresses a significant limitation in the resolver whereby we
avoid choosing the latest versions of packages when the user supports a
wider range.
For example, with NumPy, the latest versions only support Python 3.10
and later. If you lock a project with `requires-python = ">=3.8"`, we
pick the last NumPy version that supported Python 3.8, and use that for
_all_ Python versions. So you get `1.24.4` for all versions, rather than
`2.2.0`. And we'll never upgrade you unless you bump your
`requires-python`. (Even worse, those versions don't have wheels for
Python 3.12, etc., so you end up building from source.)
(As-is, this is intentional. We optimize for minimizing the number of
selected versions, and the current logic does that well!)
Instead, we know recognize when a version has an elevated
`requires-python` specifier and fork. This is a new fork point, since we
need to fork once we have the package metadata, as opposed to when we
see the dependencies.
In this iteration, I've made this behavior the default. I'm sort of
undecided on whether I want to push on that... Previously, I'd suggested
making it opt-in via a setting
(https://github.com/astral-sh/uv/pull/8686).
Closes https://github.com/astral-sh/uv/issues/8492.
## Summary
This PR reimplements
[`sysconfigpatcher`](https://github.com/bluss/sysconfigpatcher) in Rust
and applies it to our Python installations at install-time, ensuring
that the `sysconfig` data is more likely to be correct.
For now, we only rewrite prefixes (i.e., any path that starts with
`/install` gets rewritten to the correct absolute path for the current
machine).
Unlike `sysconfigpatcher`, this PR does not yet do any of the following:
- Patch `pkginfo` files.
- Change `clang` references to `cc`.
A few things that we should do as follow-ups, in my opinion:
1. Rewrite
[`AR`](c1ebf8ab92/src/sysconfigpatcher.py (L61)).
2. Remove `-isysroot`, which we already do for newer builds.
## Summary
Very tricky problem whereby `workspace_root.join(path)` returns the
workspace root with a trailing slash if `path` is empty... This caused
us to accidentally _include_ excluded members during workspace
discovery, since (e.g.) `packages/seeds` doesn't match
`packages/seeds/`.
Closes
https://github.com/astral-sh/uv/issues/9832#issuecomment-2539121761.
## Summary
In CPython, it appears that `/` is not considered as a valid path in
`search_up`:
```c
static PyObject *
getpath_dirname(PyObject *Py_UNUSED(self), PyObject *args)
{
PyObject *path;
if (!PyArg_ParseTuple(args, "U", &path)) {
return NULL;
}
Py_ssize_t end = PyUnicode_GET_LENGTH(path);
Py_ssize_t pos = PyUnicode_FindChar(path, SEP, 0, end, -1);
if (pos < 0) {
return PyUnicode_FromStringAndSize(NULL, 0);
}
return PyUnicode_Substring(path, 0, pos);
}
```
```python
def search_up(prefix, *landmarks, test=isfile):
while prefix:
if any(test(joinpath(prefix, f)) for f in landmarks):
return prefix
prefix = dirname(prefix)
```
Closes https://github.com/astral-sh/uv/issues/9818.
Make the local packse workflow work again:
```
# In packse:

# In uv:

```
Bugs fixed:
* The default scenario pattern didn't match anything.
* The snapshot update test command was wrong since the test
centralization
* Snapshot update failures would not be reported
I somehow got in a state where we'd fail to install with

but `python` / `python3` _were_ managed by uv, they just were linked to
an installation that was deleted.
This updates the logic to replace broken executables that are broken
symlinks. We apply this to broken links regardless of whether or not we
think the target is managed by uv.
## Summary
This has been bothering me a bit: `uv pip install "foo @
https://github.com/user/foo"` fails, telling you that it doesn't end in
a supported extension. But we should be able to tell you that it looks
like a Git repo.
When publishing, we currently ask the user to set `--publish-url` to the
upload URL and `--check-url` to the simple index URL, or the equivalent
configuration keys. But that's redundant with the `[[tool.uv.index]]`
declaration. Instead, we extend `[[tool.uv.index]]` with a `publish-url`
entry and allow passing `uv publish --index <name>`.
`uv publish --index <name>` requires the `pyproject.toml` to be present
when publishing, unlike using `--publish-url ... --check-url ...` which
can be used e.g. in CI without a checkout step. `--index` also always
uses the check URL feature to aid upload consistency.
The documentation tries to explain both approaches together, which
overlap for the check URL feature.

## Summary
This PR improves our "don't fully resolve symlinks" behavior for
`python-build-standalone` builds based on learnings from
https://github.com/indygreg/python-build-standalone/issues/380#issuecomment-2526575235.
Specifically, we can now robustly detect whether a target executable
will lead to a valid `prefix` or not, and iteratively resolve symlinks
until we find a valid target executable.
## Test Plan
### Direct symlink to `python`
Correctly resolves to the symlink target, rather than the symlink
itself.
```
❯ ln -s /Users/crmarsh/.local/share/uv/python/cpython-3.12.6-macos-aarch64-none/bin/python foo
❯ cargo run venv --python ./foo
❯ cat .venv/pyvenv.cfg
home = /Users/crmarsh/.local/share/uv/python/cpython-3.12.6-macos-aarch64-none/bin
implementation = CPython
uv = 0.5.7
version_info = 3.12.6
include-system-site-packages = false
prompt = uv
❯ .venv/bin/python -c "import sys"
```
### Symlink to the Python installation
Correctly does _not_ resolve the symlink.
```
❯ ln -s /Users/crmarsh/.local/share/uv/python/cpython-3.12.6-macos-aarch64-none bar
❯ cargo run venv --python ./bar
❯ cat .venv/pyvenv.cfg
home = /Users/crmarsh/workspace/uv/bar/bin
implementation = CPython
uv = 0.5.7
version_info = 3.12.6
include-system-site-packages = false
prompt = uv
❯ .venv/bin/python -c "import sys"
```
### Direct symlink to `python` in a symlinked Python installation
Correctly resolves the direct symlink, but not the symlink of the Python
installation.
```
❯ ln -s bar/bin/python baz
❯ cargo run venv --python ./baz
❯ cat .venv/pyvenv.cfg
home = /Users/crmarsh/workspace/uv/bar/bin
implementation = CPython
uv = 0.5.7
version_info = 3.12.6
include-system-site-packages = false
prompt = uv
❯ .venv/bin/python -c "import sys"
```
Addresses #6805
## Summary
This PR adds a `--gui-script` flag to `uv run` that allows running
Python scripts with `pythonw.exe` on Windows, regardless of file
extension. This solves the issue where users need to maintain duplicate
`.py` and `.pyw` files to run the same script with and without a console
window.
The implementation follows the pattern established by the existing
`--script` flag, but uses `pythonw.exe` instead of `python.exe` on
Windows. On non-Windows platforms, the flag is present but returns an
error indicating it's Windows-only functionality.
Changes:
- Added `--gui-script` flag (Windows-only)
- Added Windows test to verify GUI script behavior
- Added non-Windows test to verify proper error message
- Updated CLI documentation
## Test Plan
The changes are tested through:
1. New Windows-specific test that verifies:
- Script runs successfully with `pythonw.exe` when using `--gui-script`
- Console output is suppressed in GUI mode but visible in regular mode
- Same script can be run both ways without modification
2. New non-Windows test that verifies:
- Appropriate error message when `--gui-script` is used on non-Windows
platforms
3. Documentation updates to clearly indicate Windows-only functionality

Supersedes https://github.com/astral-sh/uv/pull/8517 with an alternative
approach of making all the variants available instead of replacing the
x86_64 (v1) variant with x86_64_v2.
Doesn't add automatic inference of the supported instructions, but that
should be doable per @charliermarsh's comment there. Going to do it as a
follow-up since this has been pretty time consuming.
e.g.,
```
❯ cargo run -q -- python install cpython-3.12.8-linux-x86_64_v3-gnu
Installed Python 3.12.8 in 2.72s
+ cpython-3.12.8-linux-x86_64_v3-gnu

❯ uv python install foo
error: Cannot download managed Python for request: directory `foo`
❯ cargo run -q -- python install foo
error: `foo` is not a valid Python download request; see `uv python help` for supported formats and `uv python list --only-downloads` for available versions
```
## Summary
This optimization isn't quite right, because we can successfully extract
metadata without having to build from source. (The builder itself will
error if we reach the point at which we need to build, but builds are
disabled.)
Closes https://github.com/astral-sh/uv/issues/9776.
## Summary
If you look at Ed's reply
[here](https://github.com/toml-rs/toml/issues/818#issuecomment-2532626305),
it sounds like we're being too heavy-handed in applying `.fmt()`. I
think I added this to handle an issue with inline tables whereby we were
inserting a space after a trailing comma? So now I'm just applying
`.fmt()` to inline tables, which don't allow comments between elements
anyway.
Closes https://github.com/astral-sh/uv/issues/9758.
Since we don't (currently) include conflict markers with our
`resolution-markers` in the lock file, it's possible that we end up
with duplicate markers. This happens when the resolver creates more
than one fork with the same PEP 508 markers but different conflict
markers, _and_ where those PEP 508 markers don't simplify to "always
true" after accounting for `requires-python`.
This change should be a strict improvement on the status quo. We aren't
removing any information. It is possible that we should be writing
conflict markers here (like we do for dependency edges), but I haven't
been able to come up with a case or think through a scenario where they
are necessary.

The resolver methods are already too large and complex, especially
`choose_version*`, so i wanted to shrink and simplify them a bit before
adding new methods to them.
I've split `MetadataResponse` into three variants: success, non-fatal
error (reported through pubgrub), fatal error (reported as error trace).
The resulting non-fatal `MetadataUnavailable` type is equivalent to the
`IncompletePackage` type, so they are now merged. (`UnavailableVersion`
is a bit different since, besides the extra `IncompatibleDist` variant,
it have no error source attached). This shows that the missing metadata
variant was unused, which I removed.
Tagging as error messages for the logging format changes.
This PR adds a notion of "conflict markers" to the lock file as an
attempt to address #9289. The idea is to encode a new kind of boolean
expression indicating how to choose dependencies based on which extras
are activated.
As an example of what conflict markers look like, consider one of the
cases
brought up in #9289, where `anyio` had unconditional dependencies on
two different versions of `idna`. Now, those are gated by markers, like
this:
```toml
[[package]]
name = "anyio"
version = "4.3.0"
source = { registry = "https://pypi.org/simple" }
dependencies = [
{ name = "idna", version = "3.5", source = { registry = "https://pypi.org/simple" }, marker = "extra == 'extra-7-project-foo'" },
{ name = "idna", version = "3.6", source = { registry = "https://pypi.org/simple" }, marker = "extra == 'extra-7-project-bar' or extra != 'extra-7-project-foo'" },
{ name = "sniffio" },
]
```
The odd extra values like `extra-7-project-foo` are an encoding of not
just the conflicting extra (`foo`) but also the package it's declared
for (`project`). We need both bits of information because different
packages may have the same extra name, even if they are completely
unrelated. The `extra-` part is a prefix to distinguish it from groups
(which, in this case, would be encoded as `group-7-project-foo` if `foo`
were a dependency group). And the `7` part indicates the length of the
package name which makes it possible to parse out the package and extra
name from this encoding. (We don't actually utilize that property, but
it seems like good sense to do it in case we do need to extra
information from these markers.)
While this preserves PEP 508 compatibility at a surface level, it does
require utilizing this encoding scheme in order
to evaluate them when they're present (which only occurs when
conflicting extras/groups are declared).
My sense is that the most complex part of this change is not just adding
conflict markers, but their simplification. I tried to address this in
the code comments and commit messages.
Reviewers should look at this commit-by-commit.
Fixes#9289, Fixes#9546, Fixes#9640, Fixes#9622, Fixes#9498, Fixes
#9701, Fixes#9734
## Summary
So the error here is:
```rust
ExtractError("cpython-3.11.11%2B20241206-aarch64-apple-darwin-install_only_stripped.tar.gz", Io(Custom { kind: UnexpectedEof, error: TarError { desc: "failed to unpack `/Users/crmarsh/.local/share/uv/python/.cache/.tmpkqFzqE/python/lib/libpython3.11.dylib`", io: Custom { kind: UnexpectedEof, error: TarError { desc: "failed to unpack `python/lib/libpython3.11.dylib` into `/Users/crmarsh/.local/share/uv/python/.cache/.tmpkqFzqE/python/lib/libpython3.11.dylib`", io: Custom { kind: UnexpectedEof, error: "unexpected end of file" } } } } }))
```
This isn't a Reqwest error, so we miss it in
`is_extended_transient_error`.
We could add `TarError` or `ExtractError` here, but... should we? This
PR just extends it to any error that has an IO source. I don't see much
of a downside.
Closes https://github.com/astral-sh/uv/issues/9747.
## Test Plan
First, ran: `uv run ./scripts/create-python-mirror.py --name cpython
--arch aarch64 --os darwin`.
Then, dropped this into `./scripts/mirror/server.py`:
```python
import os
import random
from http.server import SimpleHTTPRequestHandler, HTTPServer
class GlitchyStaticServer(SimpleHTTPRequestHandler):
def do_GET(self):
"""Handle GET request."""
file_path = self.translate_path(self.path)
if not os.path.exists(file_path):
self.send_error(404, "File not found")
return
try:
with open(file_path, 'rb') as f:
file_content = f.read()
# Introduce an "unexpected end of file" glitch randomly
if random.random() < 0.75: # 75% chance of glitch
glitch_point = random.randint(1, len(file_content) - 1)
file_content = file_content[:glitch_point]
self.send_response(200)
self.send_header("Content-type", self.guess_type(file_path))
self.send_header("Content-Length", len(file_content))
self.end_headers()
self.wfile.write(file_content)
except Exception as e:
self.send_error(500, f"Internal Server Error: {e}")
def run(server_class=HTTPServer, handler_class=GlitchyStaticServer, port=8080):
"""Run the server."""
server_address = ('', port)
httpd = server_class(server_address, handler_class)
print(f"Serving on port {port} with glitchy behavior")
httpd.serve_forever()
if __name__ == "__main__":
run()
```
Then ran `python server.py` from that directory.
From there, ran `UV_PYTHON_INSTALL_MIRROR="http://localhost:8080" cargo
run python install 3.11 --reinstall --verbose` to reliably test retries.
## Summary
I'm not sure why this hasn't come up before... But it looks like this
method is only looking at `python.exe` and `python3.exe`? From the user
screenshots, the `python3.12.exe` and `python3.13.exe` are also present,
though.
Closes https://github.com/astral-sh/uv/issues/9667.
I don't see any real reason to forbid executing these in a
cross-platform way
```
❯ echo "print('hello world')" > test.pyw
❯ uv run test.pyw
error: Failed to spawn: `test.pyw`
Caused by: No such file or directory (os error 2)
❯ cargo run -q -- run test.pyw
hello world
```
Closes https://github.com/astral-sh/uv/issues/9757
## Summary
On `main`, if you ask for a source but name a missing subdirectory, you
just get:
```
{source} does not appear to be a Python project, as neither `pyproject.toml` nor `setup.py` are present in the directory
```
But, in reality, the directory doesn't exist at all.
## Summary
We were reading an `.egg-info` file from the root directory that didn't
apply to the root member -- it was for another workspace member. I think
this is driven from some idiosyncracies in the `setuptools` setup for
that workspace member, but it's still wrong to fail.
This PR adds a few measures to fix this:
1. We validate the `egg-info` filename against the package metadata.
2. We skip, rather than fail, if we see incorrect metadata in an
`egg-info` file or similar. This is an optimization anyway; worst case,
we try to build the package, then fail there.
Closes https://github.com/astral-sh/uv/issues/9743.
The `SysVersion` registry entry may or may not include the patch
version, so if we encounter a registry entry without a patch version, we
must not assume that the patch version is 0.

## Summary
This PR allows users to specify a source both in `project.dependencies`
("production") and `tool.uv.sources` ("development"). It's not intended
as a holistic fix for "production" vs. "development" dependencies, but
in some cases this is good enough with `--no-sources`, and I don't see a
great reason for enforcing it right now.
Closes: https://github.com/astral-sh/uv/issues/9682
Ref: https://github.com/astral-sh/uv/issues/7945 (but I'll leave this
open?)
## 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.
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
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.
Using the directory writer trait, we can collect the files instead of
writing them to a real sink. This builds up to a `uv build --list`
similar to `cargo package --list`. It is not connected to the cli yet.
## Summary
Discovered while working on https://github.com/astral-sh/uv/issues/9516.
In the linked repo, the root uses a `../dependency` path for the
workspace member, which we weren't normalizing.
## Summary
If a Git repository uses a `path` dependency (rather than a
`workspace`), we need to expand the path to make it relative to the Git
root.
Closes https://github.com/astral-sh/uv/issues/9516.
## Summary
Include the `git_member` when fetching metadata from cache.

Adds a `--default` flag to `uv python install` in preview. This includes
a `python` and `python{major}` executable in addition to the
`python{major}.{minor}` executable. We will replace uv-managed
executables, but externally managed executables require the `--force`
flag to overwrite.
If you run `uv python install` (without arguments), we include the
`--default` flag implicitly to populate `python` and `python3` for the
"default" install version.
In the future, we should add a warning if the installed executable isn't
at the front of the PATH.
## Summary
Fixes#9027
Minor enhancement on top of #8531 that makes the CLI parameter
`--check-url` also available as the setting `check-url` in configuration
files.
## Test Plan
Updates existing tests to take the new setting into account.
Within publish command testing I didn't see existing tests covering
settings from toml files (instead of from CLI params), so I didn't add
anything of that sort.
## Summary
On Windows, non-virtual environments put the `python.exe` in the
top-level of the installation directory, rather than in `Scripts`. This
PR adds those paths to `PATH` in `uv run` and `uv tool run`.
Closes
https://github.com/astral-sh/uv/issues/9574#issuecomment-2512217110.
This _partially_ unwinds the optimization in #9540 by adding back the
base package dependency as a sibling to the extra package dependency
in some cases. Specifically, this occurs when _any_ of the extras are
declared as conflicting.
This is believed to be necessary (until another method is found) to
handle the forking logic based on conflicts. Namely, the forking logic
depends on the base and extra packages being sibling dependencies. If
only the extra is present, then it won't be included in the fork that
excludes all conflicting extras. And that means the base package won't
either, even though it should be included in that fork in some cases. If
the base package dependency is deferred, then it will never be reached.
This also adds another test and updates the snapshots that would have
caught the regression in #9540 if the conflict tests had been enabled.
Embarrassingly, PR #9474 moved the conflicting extras/groups tests into
their own module, but never actually included the module in
`it/main.rs`.
This adds `lock_conflict` to `main.rs` and fixes the fallout.
For listing files, we first use a directory writer for source dists,
which we will use for collecting the filenames instead of writing the
archive in the future. I've split breaking `lib.rs` of uv-build-backend
into modules into the next PR.
No logic changes, only restructuring.
