## 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.
## Summary
Adds regular expression based version filter to python mirror script.
## Test Plan
Manually using `uv run ./scripts/create-python-mirror.py --name cpython
--arch x86_64 --os linux --version "3.13.\d+$"`
## Summary
The architecture details in `crates/uv-python/download-metadata.json` is
now a dictionary with family and variant data, whereas it used to be a
string. This patches the architecture filter in
`scripts/create-python-mirror.py` to support both scenarios.
## Test Plan
Tested manually using `uv run ./scripts/create-python-mirror.py --name
cpython --arch x86_64 --os linux --from-all-history`
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.
From PEP 517:
> All command-line scripts provided by the build-required packages must
be present in the build environment’s PATH. For example, if a project
declares a build-requirement on flit, then the following must work as a
mechanism for running the flit command-line tool:
>
> ```python
> import subprocess
> import shutil
> subprocess.check_call([shutil.which("flit"), ...])
> ```

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
```
