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.

## Summary
This PR adds `--install-dir` argument for the following commands:
- `uv python install`
- `uv python uninstall`
The `UV_PYTHON_INSTALL_DIR` env variable can be used to set it
(previously it was also used internally).
Any more commands we would want to add this to?
## Test Plan
For now just manual test (works on my machine hehe)
```
❯ ./target/debug/uv python install --install-dir /tmp/pythons 3.8.12
Searching for Python versions matching: Python 3.8.12
Installed Python 3.8.12 in 4.31s

```
Open to add some tests after the initial feedback.

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.
