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.

By default, Rust does not support safe cast from `&U` to `&T` for
`#[repr(transparent)] T(U)` even if the newtype opts in. The dtolnay
ref-cast crate fills this gap, allowing to remove `DisplaySafeUrlRef`.
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.

[Compare
Source](https://redirect.github.com/BurntSushi/jiff/compare/0.2.13...0.2.14)
\===================
This release includes a smattering of bug fixes, and hopefully a small
improvement to the time it takes to compile Jiff. Also, in this release,
when
`TZ` is set to a non-empty but invalid value, Jiff will always fall back
to
`Etc/Unknown` when using `TimeZone::system()`. This differs from
previous
behavior where Jiff would, in this case, attempt to read the system's
default
time zone. This change brings Jiff into consistency with existing Unix
tooling
like `date`, and is also arguably a better failure mode. That is, when
`TZ` is
set but invalid, we shouldn't silently fall back to the default system
time
zone, but instead do something that indicates something has potentially
gone
wrong.
Enhancements:
- [#​364](https://redirect.github.com/BurntSushi/jiff/issues/364):
Jiff now falls back to `Etc/Unknown` for invalid `TZ` values.
- [#​379](https://redirect.github.com/BurntSushi/jiff/pull/379):
Improve compilation times.
Bug fixes:
- [#​365](https://redirect.github.com/BurntSushi/jiff/issues/365):
Fixes a compile error in Jiff when only the `tzdb-concatenated` feature
was
enabled.
- [#​366](https://redirect.github.com/BurntSushi/jiff/issues/366):
Fixes slow initial `Zoned::now()` in environments where
`/usr/share/zoneinfo`
is on a very slow file system (like CI environments).
- [#​376](https://redirect.github.com/BurntSushi/jiff/issues/376):
Avoids searching for a tzdb at `/usr/share/zoneinfo` on Windows.

This PR redacts credentials in displayed URLs.
It mostly relies on a `redacted_url` function (and where possible
`IndexUrl::redacted`). This is a quick way to prevent leaked credentials
but it's prone to programmer error when adding new trace statements. A
better follow-on would use a `RedactedUrl` type with the appropriate
`Display` implementation. This would allow us to still extract
credentials from the URL while displaying it securely. On the plus side,
the sites where the `redacted_url` function are used serve as easy
signposts for where to use the new type in a future PR.
Closes#1714.

## Summary
If a set of wheel tags includes a dot, this code is treating the part
_after_ the dot as an extension, and thereby failing to detect that the
entry is a symlink to an archive (and thereby removing the archive).
This is all an optimization, so this code just makes it a little
targeted: we skip specific known extensions, rather than anything with
any extension.
Closes https://github.com/astral-sh/uv/issues/13270.
PEP 639 does not allow any characters that aren't in either their
limited glob syntax or the alphanumeric Unicode characters. This means
there's no way to express a glob such as `**/@test` for the excludes.
We extend the glob syntax from PEP 639 by introducing backslash escapes,
which can escape all characters but path separators (forward and
backwards slashes) to be parsed verbatim.
This means we have two glob parsers: The strict PEP 639 parser for
`project.license-files`, and our extended parser for `tool.uv`, with a
slight difference if you need to use special characters, to both adhere
to PEP 639 and to support cases such as #13280.
Fixes#13280

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
## Summary
If you use `--torch-backend=auto`, we want to avoid selecting (e.g.) a
`+cu124` build of `torch` alongside a `+cu126` build of `torchvision`.
This PR restores #13041 and integrates two PRs from @zanieb:
* #13038
* #13040
It also adds tests for relative URI and fragment handling.
Closes#13037.
