Prior to this PR, there were numerous places where uv would leak
credentials in logs. We had a way to mask credentials by calling methods
or a recently-added `redact_url` function, but this was not secure by
default. There were a number of other types (like `GitUrl`) that would
leak credentials on display.
This PR adds a `DisplaySafeUrl` newtype to prevent leaking credentials
when logging by default. It takes a maximalist approach, replacing the
use of `Url` almost everywhere. This includes when first parsing config
files, when storing URLs in types like `GitUrl`, and also when storing
URLs in types that in practice will never contain credentials (like
`DirectorySourceUrl`). The idea is to make it easy for developers to do
the right thing and for the compiler to support this (and to minimize
ever having to manually convert back and forth). Displaying credentials
now requires an active step. Note that despite this maximalist approach,
the use of the newtype should be zero cost.
One conspicuous place this PR does not use `DisplaySafeUrl` is in the
`uv-auth` crate. That would require new clones since there are calls to
`request.url()` that return a `&Url`. One option would have been to make
`DisplaySafeUrl` wrap a `Cow`, but this would lead to lifetime
annotations all over the codebase. I've created a separate PR based on
this one (#13576) that updates `uv-auth` to use `DisplaySafeUrl` with
one new clone. We can discuss the tradeoffs there.
Most of this PR just replaces `Url` with `DisplaySafeUrl`. The core is
`uv_redacted/lib.rs`, where the newtype is implemented. To make it
easier to review the rest, here are some points of note:
* `DisplaySafeUrl` has a `Display` implementation that masks
credentials. Currently, it will still display the username when there is
both a username and password. If we think is the wrong choice, it can
now be changed in one place.
* `DisplaySafeUrl` has a `remove_credentials()` method and also a
`.to_string_with_credentials()` method. This allows us to use it in a
variety of scenarios.
* `IndexUrl::redacted()` was renamed to
`IndexUrl::removed_credentials()` to make it clearer that we are not
masking.
* We convert from a `DisplaySafeUrl` to a `Url` when calling `reqwest`
methods like `.get()` and `.head()`.
* We convert from a `DisplaySafeUrl` to a `Url` when creating a
`uv_auth::Index`. That is because, as mentioned above, I will be
updating the `uv_auth` crate to use this newtype in a separate PR.
* A number of tests (e.g., in `pip_install.rs`) that formerly used
filters to mask tokens in the test output no longer need those filters
since tokens in URLs are now masked automatically.
* The one place we are still knowingly writing credentials to
`pyproject.toml` is when a URL with credentials is passed to `uv add`
with `--raw`. Since displaying credentials is no longer automatic, I
have added a `to_string_with_credentials()` method to the `Pep508Url`
trait. This is used when `--raw` is passed. Adding it to that trait is a
bit weird, but it's the simplest way to achieve the goal. I'm open to
suggestions on how to improve this, but note that because of the way
we're using generic bounds, it's not as simple as just creating a
separate trait for that method.
Rustfmt introduces a lot of formatting changes in the 2024 edition. To
not break everything all at once, we split out the set of formatting
changes compatible with both the 2021 and 2024 edition by first
formatting with the 2024 style, and then again with the currently used
2021 style.
Notable changes are the formatting of derive macro attributes and lines
with overly long strings and adding trailing semicolons after statements
consistently.

Fixes#11970.
## Test Plan
<!-- How was it tested? -->
Ran `cargo nextest`
uv’s default index strategy was designed with dependency confusion
attacks in mind. [According to the
docs](https://docs.astral.sh/uv/configuration/indexes/#searching-across-multiple-indexes),
“if a package exists on an internal index, it should always be installed
from the internal index, and never from PyPI”. Unfortunately, this is
not true in the case where authentication fails on that internal index.
In that case, uv will simply try the next index (even on the
`first-index` strategy). This means that uv is not secure by default in
this common scenario.
This PR causes uv to stop searching for a package if it encounters an
authentication failure at an index. It is possible to opt out of this
behavior for an index with a new `pyproject.toml` option
`ignore-error-codes`. For example:
```
[[tool.uv.index]]
name = "my-index"
url = "<index-url>"
ignore-error-codes = [401, 403]
```
This will also enable users to handle idiosyncratic registries in a more
fine-grained way. For example, PyTorch registries return a 403 when a
package is not found. In this PR, we special-case PyTorch registries to
ignore 403s, but users can use `ignore-error-codes` to handle similar
behaviors if they encounter them on internal registries.
Depends on #12651Closes#9429Closes#12362
Some registries (like Azure Artifact) can require you to authenticate
separately for every package URL if you do not authenticate for the
/simple endpoint. These changes make the auth middleware aware of index
URL endpoints and attempts to fetch keyring credentials for such an
index URL when making a request to any URL it's a prefix of.
The current uv behavior is to cache credentials either at the request
URL or realm level. But with these changes, we also need to cache
credentials at the index level. Note that when uv does not detect an
index URL for a request URL, it will continue to apply the old behavior.
Addresses part of #4056Closes#4583Closes#11236Closes#11391Closes#11507
This PR restores the `bogus_redirect` test that was
non-deterministically hanging (reverting #13076).
Mismatched package and distribution names were causing uv to hang prior
to #12917 (which added the `bogus_redirect` test). But with that fix, uv
was only checking for mismatched package names on the main thread (and
not the resolver thread). This allowed for a race condition which would
prevent uv from ever doing the check, triggering the original hang
condition. This PR adds the check to the resolver thread to prevent this
race condition.
## Summary
We accept `pylock.toml` as a requirements file (e.g., `uv sync
pylock.toml` or `uv pip install -r pylock.toml`). When you provide a
`pylock.toml` file, we don't allow you to provide other requirements, or
constraints, etc. And you can only provide one `pylock.toml` file, not
multiple.
We might want to remove this from `uv pip install` for now, since `pip`
may end up with a different interface (whereas `uv pip sync` is already
specific to uv), and most of the arguments aren't applicable (like
`--resolution`, etc.). Regardless, it's behind `--preview` for both
commands.
This will in principle fix the problem reported in #12611 that
`authenticate = "always"` is ignored for an index when `explicit =
true`. This change ensures all indexes are added to the URL auth
policies list passed to our auth middleware.

## Summary
This PR extends `[[tool.uv.index]]` to support `--find-links`-style
"flat" indexes, so that users can point to such indexes without using
`--find-links` _and_ get access to the full functionality of
`[[tool.uv.index]]` (e.g., they can now pin packages to
`--find-links`-style indexes).
Note that, at present, `--find-links` indexes actually have some quirky
behavior, in that we combine them into a single entity and then merge
the discovered distributions into each Simple API-style index. The
motivation here, IIRC, was to match pip's behavior quite closely. I'm
interested in _removing_ that behavior, but it'd be breaking (and may
also be inconvenient for some use-cases). So, the behavior for indexes
passed in via `--find-links` remains completely unchanged. However,
`[[tool.uv.index]]` entries with `format = "flat"` are now treated
identically to those defined with `format = "simple"` (the default), in
that we stop after we find the first-matching index, etc.
Closes https://github.com/astral-sh/uv/issues/11634.
## Summary
I don't know if I actually want to commit this, but I did it on the
plane last time and just polished it off (got it to compile) while
waiting to board.
## Summary
This PR modifies the requirement source entities to store a (new)
container struct that wraps `IndexUrl`. This will allow us to store
user-defined metadata alongside `IndexUrl`, and propagate that metadata
throughout resolution.
Specifically, I need to store the "kind" of the index (Simple API vs.
`--find-links`), but I also ran into this problem when I tried to add
support for overriding `Cache-Control` headers on a per-index basis: at
present, we have no way to passing around metadata alongside an
`IndexUrl`.
## Summary
We respect `--exclude-newer` during resolution, but we weren't applying
it to individual _files_ when writing the lockfile. As a result, if
wheels were added to a distribution after its initial release, we'd end
up including them in the lockfile, even if they were uploaded after the
`--exclude-newer` date.
Closes https://github.com/astral-sh/uv/issues/12296.
## Summary
This crate is for standards-compliant types, but this is explicitly a
type that's custom to uv. It's also strange because we kind of want to
reference `IndexUrl` on the registry type, but that's in a crate that
_depends_ on `uv-pypi-types`, which to me is a sign that this is off.
## Summary
This is a prototype that I'm considering shipping under `--preview`,
based on [`light-the-torch`](https://github.com/pmeier/light-the-torch).
`light-the-torch` patches pip to pull PyTorch packages from the PyTorch
indexes automatically. And, in particular, `light-the-torch` will query
the installed CUDA drivers to determine which indexes are compatible
with your system.
This PR implements equivalent behavior under `--torch-backend auto`,
though you can also set `--torch-backend cpu`, etc. for convenience.
When enabled, the registry client will fetch from the appropriate
PyTorch index when it sees a package from the PyTorch ecosystem (and
ignore any other configured indexes, _unless_ the package is explicitly
pinned to a different index).
Right now, this is only implemented in the `uv pip` CLI, since it
doesn't quite fit into the lockfile APIs given that it relies on feature
detection on the currently-running machine.
## Test Plan
On macOS, you can test this with (e.g.):
```shell
UV_TORCH_BACKEND=auto UV_CUDA_DRIVER_VERSION=450.80.2 cargo run \
pip install torch --python-platform linux --python-version 3.12
```
On a GPU-enabled EC2 machine:
```shell

```
## Summary
This ended up being more involved than expected. The gist is that we
setup all the packages we want to reinstall upfront (they're passed in
on the command-line); but at that point, we don't have names for all the
packages that the user has specified. (Consider, e.g., `uv pip install
.` -- we don't have a name for `.`, so we can't add it to the list of
`Reinstall` packages.)
Now, `Reinstall` also accepts paths, so we can augment `Reinstall` based
on the user-provided paths.
Closes#12038.
This is a minimal redux of #10861 to be compatible with `uv pip`.
This implements the interface described in:
https://github.com/pypa/pip/pull/13065#issuecomment-2544000876 for `uv
pip install` and `uv pip compile`. Namely `--group <[path:]name>`, where
`path` when not defined defaults to `pyproject.toml`.
In that interface they add `--group` to `pip install`, `pip download`,
and `pip wheel`. Notably we do not define `uv pip download` and `uv pip
wheel`, so for parity we only need to implement `uv pip install`.
However, we also support `uv pip compile` which is not part of pip
itself, and `--group` makes sense there too.
----
The behaviour of `--group` for `uv pip` commands makes sense for the
cases upstream pip supports, but has confusing meanings in cases that
only we support (because reading pyproject.tomls is New Tech to them but
heavily supported by us). **Specifically case (h) below is a concerning
footgun, and case (e) below may get complaints from people who aren't
well-versed in dependency-groups-as-they-pertain-to-wheels.**
## Only Group Flags
Group flags on their own work reasonably and uncontroversially, except
perhaps that they don't do very clever automatic project discovery.
a) `uv pip install --group path/to/pyproject.toml:mygroup` pulls up
`path/to/project.toml` and installs all the packages listed by its
`mygroup` dependency-group (essentially treating it like another kind of
requirements.txt). In this regard it functions similarly to
`--only-group` in the rest of uv's interface.
b) `uv pip install --group mygroup` is just sugar for `uv pip install
--group pyproject.toml:mygroup` (**note that no project discovery
occurs**, upstream pip simply hardcodes the path "pyproject.toml" here
and we reproduce that.)
c) `uv pip install --group a/pyproject.toml:groupx --group
b/pyproject.toml:groupy`, and any other instance of multiple `--group`
flags, can be understood as completely independent requests for the
given groups at the given files.
## Groups With Named Packages
Groups being mixed with named packages also work in a fairly
unsurprising way, especially if you understand that things like
dependency-groups are not really supposed to exist on pypi, they're just
for local development.
d) `uv pip install mypackage --group path/to/pyproject.toml:mygroup`
much like multiple instances of `--group` the two requests here are
essentially completely independent: pleases install `mypackage`, and
please also install `path/to/pyproject.toml:mygroup`.
e) `uv pip install mypackage --group mygroup` is exactly the same, but
this is where it becomes possible for someone to be a little confused,
as you might think `mygroup` is supposed to refer to `mypackage` in some
way (it can't). But no, it's sourcing `pyproject.toml:mygroup` from the
current working directory.
## Groups With Requirements/Sourcetrees/Editables
Requirements and sourcetrees are where I expect users to get confused.
It behaves *exactly* the same as it does in the previous sections but
you would absolutely be forgiven for expecting a different behaviour.
*Especially* because `--group` with the rest of uv *does* do something
different.
f) `uv pip install -r a/pyproject.toml --group b/pyproject.toml:mygroup`
is again just two independent requests (install `a/pyproject.toml`'s
dependencies, and `b/pyproject.toml`'s `mygroup`).
g) `uv pip install -r pyproject.toml --group mygroup` is exactly like
the previous case but *incidentally* the two requests refer to the same
file. What the user wanted to happen is almost certainly happening, but
they are likely getting "lucky" here that they're requesting something
simple.
h) `uv pip install -r a/pyproject.toml --group mygroup` is again exactly
the same but the user is likely to get surprised and upset as this
invocation actually sources two different files (install
`a/pyproject.toml`'s dependencies, and `pyproject.toml`'s `mygroup`)! I
would expect most people to assume the `--group` flag here is covering
all applicable requirements/sourcetrees/editables, but no, it continues
to be a totally independent reference to a file with a hardcoded
relative path.

Fixes https://github.com/astral-sh/uv/issues/8590
Fixes https://github.com/astral-sh/uv/issues/8969
Adds a new optional key `auth-policy` to `[tool.uv.index]` that sets the
authentication policy for the index URL.
The default is `"auto"`, which attempts to authenticate when necessary.
`"always"` always attempts to authenticate and fails if the endpoint is
unauthenticated. `"never"` never attempts to authenticate.
These policy address two kinds of cases:
* Some indexes don’t fail on unauthenticated requests; instead they just
forward to the public PyPI. This can leave the user confused as to why
their package is missing. The "always" policy prevents this.
* "never" allows users to ensure their credentials couldn't be leaked to
an unexpected index, though it will only allow for successful requests
on an index that doesn't require credentials.
Closes#11600
Three edition 2021 compatible sets of changes in preparation for the
edition 2025 split out from #11724.
In edition 2025, `gen` is a keyword, so we escape it as `r#gen`. `ref`
and `ref mut` are not allowed anymore for `&T` and `&mut T`, so we
remove them. `cargo fmt` now formats inside of macros, which the 2021
formatter doesn't undo.
## Summary
This is the pattern I see in a variety of crates, and I believe this is
preferred if you don't _need_ an owned `String`, since you can avoid the
allocation. This could be pretty impactful for us?
## Summary
* Upgrade the rust toolchain to 1.85.0. This does not increase the MSRV.
* Update windows trampoline to 1.86 nightly beta (previously in 1.85
nightly beta).
## Test Plan
Existing tests
Solving spent a chunk of its time just converting resolutions, the left
two blocks:

These blocks are `ResolverOutput::from_state` with 1.3% and
`ForkState::into_resolution` with 4.1% of resolver thread runtime for
apache airflow universal.
We reduce the overhead spent in those functions, to now 1.1% and 2.1% of
resolver time spend in those functions by:
Commit 1: Replace the hash set for the edges with a vec in
`ForkState::into_resolution`. We deduplicate edges anyway when
collecting them, and the hash-and-insert was slow.
Commit 2: Reduce the distribution clonign in
`ResolverOutput::from_state` by using an `Arc`.
The same profile excerpt for the resolver with the branch (note that
there is now an unrelated block between the two we optimized):

Wall times are noisy, but the profiles show those changes as
improvements.

Initially, we were limiting Git schemes to HTTPS and SSH as only
supported schemes. We lost this validation in #3429. This incidentally
allowed file schemes, which apparently work with Git out of the box.
A caveat for this is that in tool.uv.sources, we parse the git field
always as URL. This caused a problem with #11425: repo = { git =
'c:\path\to\repo', rev = "xxxxx" } was parsed as a URL where c: is the
scheme, causing a bad error message down the line.
This PR:
* Puts Git URL validation back in place. It bans everything but HTTPS,
SSH, and file URLs. This could be a breaking change, if users were using
a git transport protocol were not aware of, even though never
intentionally supported.
* Allows file: URL in Git: This seems to be supported by Git and we were
supporting it albeit unintentionally, so it's reasonable to continue to
support it.
* It does not allow relative paths in the git field in tool.uv.sources.
Absolute file URLs are supported, whether we want relative file URLs for
Git too should be discussed separately.
Closes#3429: We reject the input with a proper error message, while
hinting the user towards file:. If there's still desire for relative
path support, we can keep it open.

We want to build `uv-build` without depending on the network crates. In
preparation for that, we split uv-git into uv-git and uv-git-types,
where only uv-git depends on reqwest, so that uv-build can use
uv-git-types.
## Summary
This PR revives https://github.com/astral-sh/uv/pull/10017, which might
be viable now that we _don't_ enforce any platforms by default.
The basic idea here is that users can mark certain platforms as required
(empty, by default). When resolving, we ensure that the specified
platforms have wheel coverage, backtracking if not.
For example, to require that we include a version of PyTorch that
supports Intel macOS:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.11"
dependencies = ["torch>1.13"]
[tool.uv]
required-platforms = [
"sys_platform == 'darwin' and platform_machine == 'x86_64'"
]
```
Other than that, the forking is identical to past iterations of this PR.
This would give users a way to resolve the tail of issues in #9711, but
with manual opt-in to supporting specific platforms.
## Summary
We need to add indexes in the order in which they're respected by the
resolver. Otherwise, we risk writing an index to the `pyproject.toml`
that is canonically equal (but not verbatim equivalent) to the index we
use during resolutin.
Closes https://github.com/astral-sh/uv/issues/11312.
## Summary
This lets us drop a dependency entirely. `percent-encoding` is used by
`url` and so is already in the graph, whereas `urlencoding` isn't used
by anything else.
## Summary
This PR adds an additional normalization step to `CanonicalUrl` whereby
we now percent-decode the path, to ensure that (e.g.)
`torch-2.5.1%2Bcpu.cxx11.abi-cp39-cp39-linux_x86_64.whl` and
`torch-2.5.1+cpu.cxx11.abi-cp39-cp39-linux_x86_64.whl` are considered
equal. Further, when generating the "reinstall" report, we use the
canonical URL rather than the verbatim URL.
In making this change, I also learned that we don't apply any of the
normalization passes to `file://` URLs. I inadvertently removed it in
93d606aba2,
since setting the password or URL on ` file://` URL errors -- but now
suppress those errors anyway.
Closes https://github.com/astral-sh/uv/issues/11082.
## Test Plan
- Downloaded a [PyTorch
wheel](https://download.pytorch.org/whl/cpu-cxx11-abi/torch-2.5.1%2Bcpu.cxx11.abi-cp39-cp39-linux_x86_64.whl)
- `python3.9 -m pip install
torch-2.5.1+cpu.cxx11.abi-cp39-cp39-linux_x86_64.whl --platform
linux_x86_64 --target foo --no-deps`
- `cargo run pip install
torch-2.5.1+cpu.cxx11.abi-cp39-cp39-linux_x86_64.whl --python-platform
linux --python-version 3.9 --target foo --no-deps`
- Verified that the package had the `~` symbol for the reinstall.
## One-liner
Relative find-links configuration to local path from a pyproject.toml or
uv.toml is now relative to the config file
## Summary
### Background
One can configure find-links in a `pyproject.toml` or `uv.toml` file,
which are located from the cli arg, system directory, user directory, or
by traversing parent directories until one is encountered.
This PR addresses the following scenario:
- A project directory which includes a `pyproject.toml` or `uv.toml`
file
- The config file includes a `find-links` option. (eg under `[tool.uv]`
for `pyproject.toml`)
- The `find-links` option is configured to point to a local subdirectory
in the project: `packages/`
- There is a subdirectory called `subdir`, which is the current working
directory
- I run `uv run my_script.py`. This will locate the `pyproject.toml` in
the parent directory
### Current Behavior
- uv tries to use the path `subdir/packages/` to find packages, and
fails.
### New Behavior
- uv tries to use the path `packages/` to find the packages, and
succeeds
- Specifically, any relative local find-links path will resolve to be
relative to the configuration file.
### Why is this behavior change OK?
- I believe no one depends on the behavior that a relative find-links
when running in a subdir will refer to different directories each time
- Thus this change only allows a more common use case which didn't work
previously.
## Test Plan
- I re-created the setup mentioned above:
```
UvTest/
├── packages/
│ ├── colorama-0.4.6-py2.py3-none-any.whl
│ └── tqdm-4.67.1-py3-none-any.whl
├── subdir/
│ └── my_script.py
└── pyproject.toml
```
```toml
# pyproject.toml
[project]
name = "uvtest"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = [
"tqdm>=4.67.1",
]
[tool.uv]
offline = true
no-index = true
find-links = ["packages/"]
```
- With working directory under `subdir`, previously, running `uv sync
--offline` would fail resolving the tdqm package, and after the change
it succeeds.
- Additionally, one can use `uv sync --show-settings` to show the
actually-resolved settings - now having the desired path in
`flat_index.url.path`
## Alternative designs considered
- I considered modifying the `impl Deserialize for IndexUrl` to parse
ahead of time directly with a base directory by having a custom
`Deserializer` with a base dir field, but it seems to contradict the
design of the serde `Deserialize` trait - which should work with all
`Deserializer`s
## Future work
- Support for adjusting all other local-relative paths in `Options`
would be desired, but is out of scope for the current PR.

## Summary
We can retain the small-size advantage of our new tags by moving the
"unknown tag" case into `WheelTagLarge`. This ensures that we can still
represent unknown tags, but avoid paying the cost for them.
