For some reason, I'm encountering broken PBS venvs again (https://github.com/astral-sh/python-build-standalone/issues/380). Instead of showing the obscure error to the user, we point them to the PBS bug and ask them to run `uv venv`.
```

Caused by: Python is missing PYTHONHOME. If you are using a managed Python interpreter, this is a known bug (https://github.com/astral-sh/python-build-standalone/issues/380). You can recreate the virtual environment with `uv venv`.

## Summary
This PR explicitly sets the entry type for files in an sdist. This
changes the entry type from `AREGTYPE` (the 'legacy' regular file type)
to `REGTYPE` (the 'normal' regular file type) in the generated tar.
This change works around a bug in the python `tarfile` module that
causes all entries after a certain point in the tar to be silently
ignored if any entry matches some very specific conditions. In `maturin`
this was very visible since the `PKG-INFO` was written at the very end
so `twine check` would loudly complain that the `PKG-INFO` was missing
and that the sdist was invalid. In `uv` the `PKG-INFO` is written at the
beginning so this issue is unlikely to be caught.
Note that this change does mean that sdists created with newer versions
of the uv build backend will not be byte-for-byte identical with sdists
from an older version.
See https://github.com/PyO3/maturin/issues/2855#issuecomment-3546501132
## Test Plan
This is the same as the change that was made in maturin to work around
the same issue

Follows #16814 updating the test cases with Claude so that the
timestamps and durations are on the boundary of package versions so we
see actual version changes in the lockfile.

## Summary
Gate a few more tests on the `pypi` feature. All of these fail in
offline environments because they try to communicate with PyPI.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
<!-- How was it tested? -->
Applied as a patch to Fedora’s `uv` package, version 0.9.16.
Fixed https://github.com/astral-sh/uv/issues/16821
This is already explained in the guide, but it was missing from the
reference docs.

## Summary
Update the `UV_VERSION`, such that a `copy-to-clipboard` action and
pasting into a `.gitlab-ci.yml` is not 4 minor versions behind, as it
happened to me a couple of times.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
I ran `mkdocs serve` and it worked (I literally only changed one
character)
<!-- How was it tested? -->
Adds support for "friendly" durations like, 1 week, 7 days, 24 hours
using Jiff's parser. During resolution, we calculate this relative to
the current time and resolve it into a concrete timestamp for the
lockfile. If the span has not changed, e.g., to another relative value,
then locking again will not change the lockfile. The locked timestamp
will only be updated when the lockfile is invalidated, e.g., with
`--upgrade`. This prevents the lockfile from repeatedly churning when a
relative value is used.
Resolves#16777
## Summary
When a command fails, users sometimes add --verbose after the package
name (e.g., uvx foo --verbose) instead of before it (e.g., uvx --verbose
foo). This adds a hint that suggests moving --verbose before the
command.
The hint appears when a verbose flag is detected in the subcommand
arguments and the command fails to resolve. It works for both uvx and uv
tool run.
## Test Plan
Tested by running:
uvx foo-does-not-exist --verbose - shows the hint
uv tool run foo-does-not-exist --verbose - shows the hint
The hint only appears when verbose flags are detected, and the message
shows the correct command format.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Nushell activation now computes the venv root dynamically via path self
for relocatable venvs, while non-relocatable venvs still embed a quoted
absolute path
Still keep `activate.csh` (maybe delete is also an option)

<!-- How was it tested? -->
It'd be nice to avoid churn for contributors. This is a pretty frequent
cause of CI failures and I don't think we really need to have the
reference documentation committed.
## Summary
There are a class of outcomes whereby an index might not be included in
"allowed indexes", but could still correctly appear in a lockfile. In
the linked case, we have two `default = true` indexes, and one of them
is also named. We omit the second `default = true` index from the list
of "allowed indexes", but since it's named, a dependency can reference
it explicitly. We handle this correctly for `project.dependencies`, but
the handling was incorrectly omitting dependency groups.
Closes https://github.com/astral-sh/uv/issues/16843.
Error when a built wheel is for the wrong platform. This can happen
especially when using `--python-platform` or `--python-version` with `uv
pip install`.
Fixes#16019
Resolves https://github.com/astral-sh/uv/issues/16833
`uv self update` could error with a better message if it knows the user
has installed it with brew. This diff adds an `InstallSource` we can use
the detect where a `uv` binary comes from and augment error messages
with better context. We're only adding brew for now, but it could easily
be extend with other detection heuristics.
## Summary
Given `bump-workspace-crate-versions.py` will bump all crates, we also
need to update uv-trampoline lockfile references to those new versions
(for uv-static, uv-macros) after
https://github.com/astral-sh/uv/pull/16950.
## Test Plan
Ran release script manually and verify uv-trampoline lockfile is up to
date after the changes from bump-workspace-crate-versions.py
When a process is running and another calls `uv cache clean` or `uv
cache prune` we currently deadlock - sometimes until the CI timeout
(https://github.com/astral-sh/setup-uv/issues/588). To avoid this, we
add a default 5 min timeout waiting for a lock. 5 min balances allowing
in-progress builds to finish, especially with larger native
dependencies, while also giving timely errors for deadlocks on (remote)
systems.
Commit 1 is a refactoring.
This branch also fixes a problem with the logging where acquired and
released resources currently mismatch:
```
DEBUG Acquired lock for `https://github.com/tqdm/tqdm`
DEBUG Using existing Git source `https://github.com/tqdm/tqdm`
DEBUG Released lock at `C:\Users\Konsti\AppData\Local\uv\cache\git-v0\locks\16bb813afef8edd2`
```
This was discovered by https://github.com/astral-sh/uv/pull/16074, where
the wrong tag now fails the Pyston integration test.
I'm not sure what the exact schema of the cache tag is, but since the
project is dead, I don't expect any new non-matching versions to follow.
Clarify `--project` flag help text to indicate project discovery
Update the help text for `--project` from "Run the command within
the given project directory" to "Discover a project in the given
directory" to better reflect its actual behavior.
The `--project` flag affects file discovery (pyproject.toml, uv.toml,
etc.) but does not change the working directory. Users should use
`--directory` for changing the working directory.
Fixes#16718
## Summary
Inform users who encounter #16879 that `uv pip debug` is currently
intentionally not implemented.
## Test Plan
Added an integration test for the warning, ran the test suite.
## Summary
This change updates the guide about integration with pytorch to include
the CUDA 13.0 variant.
## Test Plan
I generated the documentation and verified that it looked correct.
