Support multiple root modules in namespace packages by enumerating them:
```toml
[tool.uv.build-backend]
module-name = ["foo", "bar"]
```
This allows applications with multiple root packages without migrating to workspaces. Since those are regular module names (we iterate over them an process each one like a single module names), it allows combining dotted (namespace) names and regular names. It also technically allows combining regular and stub modules, even though this is even less recommends.
We don't recommend this structure (please use a workspace instead, or structure everything in one root module), but it reduces the number of cases that need `namespace = true`.
Fixes#14435Fixes#14438
The uv build backend has gone through some feedback cycles, we expect no
more major configuration changes, and we're ready to take the next step:
The uv build backend in stable.
This PR stabilizes:
* Using `uv_build` as build backend
* The documentation of the uv build backend
* The direct build fast path, where uv doesn't use PEP 517 if you're
using `uv_build` in a compatible version.
* `uv build --list`, which is limited to `uv_build`.
It does not:
* Make `uv_build` the default on `uv init`
* Make `--package` the default on `uv init`
We do not currently support passing index names to `--index` for
installing packages. However, we do accept relative paths that can look
like index names. This PR adds the requirement that `--index` values
must be disambiguated with a prefix (`./` or `../` on Unix and Windows
or `.\\` or `..\\` on Windows). For now, if an ambiguous value is
provided, uv will warn that this will not be supported in the future.
Currently, if you provide an index name like `--index test` when there
is no `test` directory, uv will error with a `Directory not found...`
error. That's not very informative if you thought index names were
supported. The new warning makes the context clearer.
Closes#13921
> NOTE: The PRs that were merged into this feature branch have all been
independently reviewed. But it's also useful to see all of the changes
in their final form. I've added comments to significant changes
throughout the PR to aid discussion.
This PR introduces transparent Python version upgrades to uv, allowing
for a smoother experience when upgrading to new patch versions.
Previously, upgrading Python patch versions required manual updates to
each virtual environment. Now, virtual environments can transparently
upgrade to newer patch versions.
Due to significant changes in how uv installs and executes managed
Python executables, this functionality is initially available behind a
`--preview` flag. Once an installation has been made upgradeable through
`--preview`, subsequent operations (like `uv venv -p 3.10` or patch
upgrades) will work without requiring the flag again. This is
accomplished by checking for the existence of a minor version symlink
directory (or junction on Windows).
### Features
* New `uv python upgrade` command to upgrade installed Python versions
to the latest available patch release:
```
# Upgrade specific minor version
uv python upgrade 3.12 --preview
# Upgrade all installed minor versions
uv python upgrade --preview
```
* Transparent upgrades also occur when installing newer patch versions:
```
uv python install 3.10.8 --preview
# Automatically upgrades existing 3.10 environments
uv python install 3.10.18
```
* Support for transparently upgradeable Python `bin` installations via
`--preview` flag
```
uv python install 3.13 --preview
# Automatically upgrades the `bin` installation if there is a newer patch version available
uv python upgrade 3.13 --preview
```
* Virtual environments can still be tied to a patch version if desired
(ignoring patch upgrades):
```
uv venv -p 3.10.8
```
### Implementation
Transparent upgrades are implemented using:
* Minor version symlink directories (Unix) or junctions (Windows)
* On Windows, trampolines simulate paths with junctions
* Symlink directory naming follows Python build standalone format: e.g.,
`cpython-3.10-macos-aarch64-none`
* Upgrades are scoped to the minor version key (as represented in the
naming format: implementation-minor version+variant-os-arch-libc)
* If the context does not provide a patch version request and the
interpreter is from a managed CPython installation, the `Interpreter`
used by `uv python run` will use the full symlink directory executable
path when available, enabling transparently upgradeable environments
created with the `venv` module (`uv run python -m venv`)
New types:
* `PythonMinorVersionLink`: in a sense, the core type for this PR, this
is a representation of a minor version symlink directory (or junction on
Windows) that points to the highest installed managed CPython patch
version for a minor version key.
* `PythonInstallationMinorVersionKey`: provides a view into a
`PythonInstallationKey` that excludes the patch and prerelease. This is
used for grouping installations by minor version key (e.g., to find the
highest available patch installation for that minor version key) and for
minor version directory naming.
### Compatibility
* Supports virtual environments created with:
* `uv venv`
* `uv run python -m venv` (using managed Python that was installed or
upgraded with `--preview`)
* Virtual environments created within these environments
* Existing virtual environments from before these changes continue to
work but aren't transparently upgradeable without being recreated
* Supports both standard Python (`python3.10`) and freethreaded Python
(`python3.10t`)
* Support for transparently upgrades is currently only available for
managed CPython installations

This allows you to specify requires-python on individual dependency-groups,
with the intended usecase being "oh my dev-dependencies have a higher
requires-python than my actual project".
This includes a large driveby move of the RequiresPython type to
uv-distribution-types to allow us to generate the appropriate markers at
this point in the code. It also migrates RequiresPython from
pubgrub::Range to version_ranges::Ranges, and makes several pub(crate)
items pub, as it's no longer defined in uv_resolver.
Fixes#11606
Unlike regular packages, specifying all `__init__.py` directories for a
namespace package would be very verbose There is e.g.
https://github.com/python-poetry/poetry/tree/main/src/poetry, which has
18 modules, or https://github.com/googleapis/api-common-protos which is
inconsistently nested. For both the Google Cloud SDK, there are both
packages with a single module and those with complex structures, with
many having multiple modules due to versioning through `<module>_v1`
versioning. The Azure SDK seems to use one module per package (it's not
explicitly documented but seems to follow from the process in
https://azure.github.io/azure-sdk/python_design.html#azure-sdk-distribution-packages
and
ccb0e03a3d/doc/dev/packaging.md).
For simplicity with complex projects, we add a `namespace = true` switch
which disabled checking for an `__init__.py`. We only check that there's
no `<module_root>/<module_name>/__init__.py` and otherwise add the whole
`<module_root>/<module_name>` folder. This comes at the cost of
`namespace = true` effectively creating an opt-out from our usual checks
that allows creating an almost entirely arbitrary package.
For simple projects with only a single module, the module name can be
dotted to point to the target module, so the build still gets checked:
```toml
[tool.uv.build-backend]
module-name = "poetry.core"
```
## Alternatives
### Declare all packages
We could make `module-name` a list and allow or require declaring all
packages:
```toml
[tool.uv.build-backend]
module-name = ["cloud_sdk.service.storage", "cloud_sdk.service.storage_v1", "cloud_sdk.billing.storage"]
```
Or for Poetry:
```toml
[tool.uv.build-backend]
module-name = [
"poetry.config",
"poetry.console",
"poetry.inspection",
"poetry.installation",
"poetry.json",
"poetry.layouts",
"poetry.masonry",
"poetry.mixology",
"poetry.packages",
"poetry.plugins",
"poetry.publishing",
"poetry.puzzle",
"poetry.pyproject",
"poetry.repositories",
"poetry.toml",
"poetry.utils",
"poetry.vcs",
"poetry.version"
]
```
### Support multiple namespaces
We could also allow namespace packages with multiple root level module:
```toml
[tool.uv.build-backend]
module-name = ["cloud_sdk.my_ext", "local_sdk.my_ext"]
```
For lack of use cases, we delegate this to creating a workspace with one
package per module.
## Implementation
Due to the more complex options for the module name, I'm moving
verification on deserialization later, dropping the source span we'd get
from serde. We also don't show similarly named directories anymore.

## Summary
I follow the advices from the IDE spell checker and grammar checker, fix
some typos, and improve the docs.
Extends https://github.com/astral-sh/uv/pull/13841 — I'll drop that
commit later after that pull request merges but it's small.
I find the split into a "Configuration" section awkward and don't think
it's helping us. Everything moved into the "Concepts" section, except
the "Environment variables" page which definitely belongs in the
reference and the "Installer" page which is fairly niche and seems
better in the reference.

This includes some initial work on adding Pyodide support (issue
#12729). It is enough to get
```
uv pip compile -p /path/to/pyodide --extra-index-url file:/path/to/simple-index
```
to work which should already be quite useful.
## Test Plan
* added a unit test for `pyodide_platform`
* integration tested manually with:
```
cargo run pip install \

## Summary
Implemented as suggested in #13761
eg.
```
$ uv tool install 'harlequin[postgres]'
$ uv tool list --show-extras
harlequin v2.1.2 [extras: postgres]
- harlequin
```
## Test Plan
Added a new test with the argument along with the others from the `uv
tool list` cli.
By default, uv uses only a lower bound in `uv add`, which avoids
dependency conflicts due to upper bounds. With this PR, this cna be
changed by setting a different bound kind. The bound kind can be
configured in `uv.toml`, as a user preference, in `pyproject.toml`, as a
project preference, or on the CLI, when adding a specific project.
We add two options that add an upper bound on the constraint, one for
SemVer (`>=1.2.3,<2.0.0`, dubbed "major", modeled after the SemVer
caret) and another one for dependencies that make breaking changes in
minor version (`>=1.2.3,<1.3.0`, dubbed "minor", modeled after the
SemVer tilde). Intuitively, the major option bumps the most significant
version component, while the minor option bumps the second most
significant version component. There is also an exact bounds option
(`==1.2.3`), though generally we recommend setting a wider bound and
using the lockfile for pinning.
Versions can have leading zeroes, such as `0.1` or `0.0.1`. For a single
leading 0, we shift the the meaning of major and minor similar to cargo.
For two or more leading zeroes, the difference between major and minor
becomes inapplicable, instead both bump the most significant component:
- major: `0.1` -> `>=0.1,<0.2`
- major: `0.0.1` -> `>=0.0.1,<0.0.2`
- major: `0.0.1.1` -> `>=0.0.1.1,<0.0.2.0`
- major: `0.0.0.1` -> `>=0.0.0.1,<0.0.0.2`
- minor: `0.1` -> `>=0.1,<0.1.1`
- minor: `0.0.1` -> `>=0.0.1,<0.0.2`
- minor: `0.0.1.1` -> `>=0.0.1.1,<0.0.2.0`
- minor: `0.0.0.1` -> `>=0.0.0.1,<0.0.0.2`
For a consistent appearance, we try to preserve the number of components
in the upper bound. For example, adding a version `2.17` with the major
option is stored as `>=2.17,<3.0`. If a version uses three components
and is greater than 0, both bounds will also use three components
(SemVer versions always have three components). Of the top 100 PyPI
packages, 8 use a non-three-component version (docutils, idna, pycparser
and soupsieve with two components, packaging, pytz and tzdata with two
component, CalVer and trove-classifiers with four component CalVer).
Example `pyproject.toml` files with the top 100 packages: [`--bounds
major`](https://gist.github.com/konstin/0aaffa9ea53c4834c22759e8865409f4)
and [`--bounds
minor`](https://gist.github.com/konstin/e77f5e990a7efe8a3c8a97c5c5b76964).
While many projects follow version scheme that roughly or directly
matches the major or minor options, these compatibility ranges are
usually not applicable for the also popular CalVer versioning.
For pre-release versions, there are two framings we could take: One is
that pre-releases generally make no guarantees about compatibility
between them and are used to introduce breaking changes, so we should
pin them exactly. In many cases however, pre-release specifiers are used
because a project needs a bugfix or a feature that hasn't made it into a
stable release, or because a project is compatible with the next version
before a final version for that release is published. In those cases,
compatibility with other packages that depend on the same library is
more important, so the desired bound is the same as it would be for the
stable release, except with the lower bound lowered to include
pre-release.
The names of the bounds and the name of the flag is up for bikeshedding.
Currently, the option is call `tool.uv.bounds`, but we could also move
it under `tool.uv.edit.bounds`, where it would be the first/only entry.

Stubs packages are different in that their name ends with `-stubs`,
their module is `<module name>-stubs` (with a dash, not the generally
legal underscore) and their modules contain a `__init__.pyi` instead of
an `__init__.py`
(https://typing.python.org/en/latest/spec/distributing.html#stub-only-packages).
We add support in the uv build backend by detecting the `-stubs` suffix.

This adopts the logic from `uv remove` for locking and syncing, as the
scope of the changes made are ultimately similar. Unlike `uv remove`
there is no support for modifying PEP723 scripts, as these are not
versioned.
In doing this the `version` command gains a truckload of args for
configuring lock/sync behaviour. Presumably most of these are passed via
settings or env files, and not of particular concern.
The most interesting additions are:
* `--frozen`: makes `uv version` work ~exactly as it did before this PR
* `--locked`: errors if the lockfile is out of date
* `--no-sync`: updates the lockfile, but doesn't run the equivalent of
`uv sync`
* `--package name`: a convenience for referring to a package in the
workspace
Note that the existing `--dry-run` flag effectively implies `--frozen` for sets and bumps.
Fixes#13254Fixes#13548
This also omits bounds on constraints, and is useful for that. This
retains `--raw-sources` as an alias. I've had this on my mind for a
while, but https://github.com/astral-sh/uv/pull/12946 reminded me of it
again.
## Summary
Add a `--show-extras` argument to the `uv tool list` cli, to show which
extra dependencies were installed with the tool.
i.e.
```bash
$ uv tool install fastapi --with requests --with typer==0.14
```
```bash
$ uv tool list --show-extras
fastapi v0.115.12 [extras: requests, typer==0.14]
- fastapi
```
## Test Plan
Added a new test function based on the others in the same file, with the
other arguments tested with the new argument as well.
See commentary at
https://github.com/astral-sh/uv/issues/9828#issuecomment-2537542100

## Summary
Part of #12838. Allow users to configure `python-downloads-json-url` in
`uv.toml` and not just from env.
I followed similar PR #8695, so same as there it's also available in the
CLI (I think maybe it's better not to be configurable from the CLI, but
since the mirror parameters are, I think it's better to do the same)
## Test Plan
<!-- How was it tested? -->
This is a reimplementation of #7248 with a new CLI interface.
The old `uv version` is now `uv self version` (also it has gained a
`--short` flag for parity).
The new `uv version` is now an interface for getting/setting the project
version.
To give a modicum of support for migration, if `uv version` is run and
we fail to find/read a `pyproject.toml` we will fallback to `uv self
version`. `uv version --project .` prevents this fallback from being
allowed.
The new API of `uv version` is as follows:
* pass nothing to read the project version
* pass a version to set the project version
* `--bump major|minor|patch` to semver-bump the project version
* `--dry-run` to show the result but not apply it
* `--short` to have the final printout contain only the final version
* `--output-format json` to get the final printout as json
```
$ uv version
myfast 0.1.0
$ uv version --bump major --dry-run
myfast 0.1.0 => 1.0.0
$ uv version 1.2.3 --dry-run
myfast 0.1.0 => 1.2.3
$ uv version 1.2.3
myfast 0.1.0 => 1.2.3
$ uv version --short
1.2.3
$ uv version --output-format json
{
"package_name": "myfast",
"version": "1.2.3",
"commit_info": null
}
```

Just a small PR to add mentions to `pylock.toml` in the CLI manual where
appropriate.
I tried to say "PEP-751 compatible lock files" when appropriate to also
include the case `r"^pylock\.([^.]+)\.toml$"`. Feel free to change that
if you think it's cluttery.
I also tried to include the "single-use" wording when it made sense.
I also have almost never used the `uv pip` interface, so maybe there are
some other minor things to add here and there about the usage of
`pylock.toml` that I missed.

## Summary
Fixes several occurrences of the minor typo “This options” for “This
option.”
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
<!-- How was it tested? -->
Since this is just a typo fix in documentation and comment strings, no
particular testing was conducted.
## Notes
The typo fixes in `crates/uv-cli/src/lib.rs` would affect
`docs/reference/cli.md`. I assumed you might want to just re-generate
the reference documention, but fixing it up manually would look like:

## Summary
This PR adds `uv export` support for [PEP
751](https://peps.python.org/pep-0751). We don't yet expose a way to
consume the generated lockfile, but it's a first step.
The logic to go from `uv.lock` to "flat set of packages to include, with
markers telling us when to include them" is all shared with the
`requirements.txt` export (and extracted in
https://github.com/astral-sh/uv/pull/12956). So most of the code is just
converting from our internal types to the PEP 751 schema.
"Only show Python downloads, exclude installed distributions." might be
misunderstood as excluding installed distributions from `uv python list
--only-downloads`, implying that versions already installed won’t be
shown.

@jtfmumm mentioned a desire for this. I'm not sure how we should do
this. I kind of want to change this to something like...
```
$ uv python find
CPython 3.13 @ <path>
$ uv python find --only-path
<path>
$ uv python find --short
<path>
$ uv python find --only-version
3.13
```
The change in defaults would be breaking though.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Support the `UV_PROJECT` environment variable to set the project
directory.
#11946
## Test Plan
<!-- How was it tested? -->
`cargo nextest run` passed except the cache_prune.
```
export UV_PROJECT=/path/to/project
uv sync
```
works.
