## Summary
The main change is that we need to have an explicit list of protocols we
_do_ support (like `https`), so that when we see a Windows absolute path
(`C:\...`), we don't treat the `C` as a protocol itself.
Closes https://github.com/astral-sh/uv/issues/1539.
## Summary
When we read `--index-url` from a `requirements.txt`, we attempt to
respect the `--index-url` provided by the CLI if it exists.
Unfortunately, `--index-url` from the CLI has a default value... so we
_never_ respect the `--index-url` in the requirements file.
This PR modifies the CLI to use `None`, and moves the default into logic
in the `IndexLocations `struct.
Closes https://github.com/astral-sh/uv/issues/1692.
Uses `--find-links` to discover vendored scenario build dependencies and
allows us to use `--index-url` instead of `--extra-index-url` to avoid
hitting the real PyPI in scenario tests.
## Summary
This fixes https://github.com/astral-sh/uv/issues/1704 by removing the
version from the produced header.
## Test Plan
Checked with clippy, and tests are updated too.
## Summary
This PR adds the `--prompt` option to `venv` subcommand.
The default behavior for `uv venv` is to create a virtual environment in
the current directory with `.venv` name. This is different from `venv` /
`virtualenv` where a user always needs to provide the virtual
environment path. This allows us to define our own behavior in the
default scenario (`uv venv`). We've decided to use the current
directory's name in that case.
Workflows:
| Command | Virtual Environment Name | Prompt |
|--------|--------|--------|
| `uv venv` | `.venv` (default) | Current directory name |
| `uv venv project` | `project` | `project` |
| `uv venv --prompt .` | `.venv` | Current directory name |
| `uv venv --prompt foobar` | `.venv` | `foobar` |
| `uv venv project --prompt foobar` | `project` | `foobar` |
Fixes#1445
## Test Plan
This is my first Rust code and I don't know how to write tests yet.
I just checked the behavior manually:
```
$ cargo build
$ mkdir t
$ cd t
$ ../target/debug/uv venv -p 3.11
$ rg -w t .venv/bin/acti*
.venv/bin/activate.csh
13:setenv VIRTUAL_ENV '/Users/inada-n/work/uv/t/.venv'
20:if ('t' != "") then
21: setenv VIRTUAL_ENV_PROMPT 't'
23: setenv VIRTUAL_ENV_PROMPT "$VIRTUAL_ENV:t:q"
38: # in which case, $prompt is undefined and we wouldn't
.venv/bin/activate
48:VIRTUAL_ENV='/Users/inada-n/work/uv/t/.venv'
59: VIRTUAL_ENV_PROMPT="t"
.venv/bin/activate.fish
61:set -gx VIRTUAL_ENV '/Users/inada-n/work/uv/t/.venv'
73:if test -n 't'
74: set -gx VIRTUAL_ENV_PROMPT 't'
.venv/bin/activate.ps1
40:if ("t" -ne "") {
41: $env:VIRTUAL_ENV_PROMPT = "t"
.venv/bin/activate.nu
6:# but then simply `deactivate` won't work because it is just an alias to hide
35: let virtual_env = '/Users/inada-n/work/uv/t/.venv'
50: let virtual_env_prompt = (if ('t' | is-empty) {
53: 't'
```

This PR introduces more robust cache healing when `uv` fails to
deserialize an existing cache entry.
("Cache healing" in this context means that if `uv` fails to
deserialize a cache entry, then it will automatically invalidate that
entry and re-generate the data. Typically by sending an HTTP request.)
Previous to some optimizations I made around deserialization, we were
already doing this. After those optimizations, deserializing a cache
policy and the payload were split into two steps. While deserializing
a cache policy retained its cache healing behavior, deserializing the
payload did not. This became an issue when #1556 landed, which changed
one of our `rkyv` data types. This in turn made our internal types
incompatible with existing cache entries. One could work-around this
by clearing `uv`'s cache with `uv clean`, but we should just do it
automatically on a cache entry by entry basis.
This does technically introduce a new cost by pessimistically cloning
the HTTP request so that we can re-send it if necessary (see the commit
messages for the knot pushing me toward this approach). So I re-ran my
favorite ad-hoc benchmark:
```
$ hyperfine -w10 --runs 50 "uv-main pip compile --cache-dir ~/astral/tmp/cache-main ~/astral/tmp/reqs/home-assistant-reduced.in -o /dev/null" "uv-test pip compile --cache-dir ~/astral/tmp/cache-test ~/astral/tmp/reqs/home-assistant-reduced.in -o /dev/null" ; A bart

1.00 ± 0.04 times faster than uv-main pip compile --cache-dir ~/astral/tmp/cache-main ~/astral/tmp/reqs/home-assistant-reduced.in -o /dev/null
```
Which is about what I expected.
We should endeavor to have a better testing strategy for these kinds of
bugs, but I think it might be a little tricky to do. I created
https://github.com/astral-sh/uv/issues/1699 to track that.
Fixes#1571

## Summary
Adds cli command / flag (`generate-shell-completion <SHELL>` /
`--generate-shell-completion <SHELL>`) to generate the completion script
for the given shell. Implemented in exactly the same way as it is done
in ruff
(https://github.com/astral-sh/ruff/blob/main/crates/ruff/src/lib.rs#L197)
Closes https://github.com/astral-sh/uv/issues/1654
## Test Plan
I've normally tested the generated script manually only for bash shell
on Ubuntu 22.04.3
```bash
$ uv --generate-shell-completion bash > /usr/share/bash-completion/completions/uv
$ uv # <TAB>
-q -h --verbose --no-cache --version clean
-v -V --no-color --cache-dir pip generate-shell-completion
-n --quiet --color --help venv help
$ uv pip # <TAB>
-q -n -V --verbose --color --cache-dir --version sync uninstall help
-v -h --quiet --no-color --no-cache --help compile install freeze
```
Resolves#1292.
## Summary
Move the yanked warnings for `uv pip sync` and `uv pip install` to the
end of the commands, as per #1292.
## Test Plan
I ran the unit tests: `cargo nextest run`
## Summary
Just as we mark virtualenvs as `gitignore`d by default, we should also
mark them as `CACHEDIR.TAG`, to ensure that they aren't included in
backups, etc.
Closes https://github.com/astral-sh/uv/issues/1648.
## Test Plan
Ran `cargo run venv` and:
```
❯ ls .venv
CACHEDIR.TAG bin lib pyvenv.cfg
```
## Summary
Added `uv` to the list of the preserved packages when building the
installer plan. In that case `uv` is not going to be removed when, for
example, using `python -m uv pip sync requirements.txt` when
requirements.txt does not contain `uv`, but `uv` is installed in that
venv.
Closes#1631
## Test Plan
Got through the example attached to
https://github.com/astral-sh/uv/issues/1631 and did see the uv deletion
in the output
```
$ python -m uv pip sync requirements.txt
Installed 1 package in 20ms
+ ruff==0.2.2
```
## Sumamry
This PR adds the `activation.bat`, `deactivation.bat` and `pyenv.bat`
files to add support for using uv from CMD.
This PR further fixes an issue with our trampoline implementation where
calling an executable like `black` failed:
```
(venv) C:\Users\Micha\astral\test>where black
C:\Users\Micha\astral\test\.venv\Scripts\black.exe
(venv) C:\Users\Micha\astral\test>black
C:\Users\Micha\AppData\Local\Programs\Python\Python312\python.exe: can't open file 'C:\\Users\\Micha\\astral\\test\\black': [Errno 2] No such file or directory
```
The issue was that CMD doesn't extend `black` to its full path before
passing it to the trampoline and our trampoline generated the command
`<python> black` instead of `<python> .venv/Scripts/black`, and Python
can't find `black` in the project directory.
This PR fixes this by using the full executable name (that we already
parsed out to discover the Python version). This adds one complication,
we need to preserve the arguments without repeating the executable name
that is the first argument.
One option is to use
[`CommandLineToArgvW`](https://learn.microsoft.com/de-de/windows/win32/api/shellapi/nf-shellapi-commandlinetoargvw)
and then serialize the arguments 1.. to a string again. I decided
against that. Win32 API calls are easy to get wrong. That's why I
implemented the parsing rules specified in
[`CommandLineToArgvW`](https://learn.microsoft.com/de-de/windows/win32/api/shellapi/nf-shellapi-commandlinetoargvw)
to skip the first argument.

## Summary
If an editable package declares a direct URL requirement, we currently
error since it's not considered an "allowed" requirement. We need to add
those URLs to the allow-list.
Closes https://github.com/astral-sh/uv/issues/1603.
## Summary
It's incorrect to pass the resolution and dependency mode down to the
`BuildDispatch`, since it means that we'll use `--no-deps` when building
source distributions. If you set resolution to `lowest`, it also means
we end up using (e.g.) the lowest version of `wheel`, which also doesn't
make sense.
It's fine to pass `--exclude-newer`.
Closes https://github.com/astral-sh/uv/issues/1355.
Closes https://github.com/astral-sh/uv/issues/1563.
This PR fixes the bug where the `BIN_NAME` replacement field wasn't
being used in the activator scripts.

As I don't have a Windows machine, I switched the `bin_name` value here
to point to `Scripts` on `unix` platform:

## Summary#1562
It turns out that `hexdump` uses an invalid source distribution format
whereby the contents aren't nested in a top-level directory -- instead,
they're all just flattened at the top-level. In looking at pip's source
(51de88ca64/src/pip/_internal/utils/unpacking.py (L62)),
it only strips the top-level directory if all entries have the same
directory prefix (i.e., if it's the only thing in the directory). This
PR accommodates these "invalid" distributions.
I can't find any history on this method in `pip`. It looks like it dates
back over 15 years ago, to before `pip` was even called `pip`.
Closes https://github.com/astral-sh/uv/issues/1376.
## Summary
This was just a missing line -- we have `dependencies.remove(&package);`
in the ~identical branch above, but it must've been an oversight to omit
it here.
Closes https://github.com/astral-sh/uv/issues/1467.
## Test Plan
`cargo test`
## Summary
It turns out that it's not uncommon to end up with repeated packages in
requirements files when running `pip-sync`, e.g., you might have
`anyio==4.0.0` specified multiple times. This PR relaxes our assertions
in the install plan to allow such repeated packages, as long as the
requirement markers are exactly the same (i.e., they are truly
duplicates).
Closes https://github.com/astral-sh/uv/issues/1552.
## Summary
If you're developing on a package like `attrs` locally, and it has a
recursive extra like `attrs[dev]`, it turns out that we then try to find
the `attrs` in `attrs[dev]` from the registry, rather than recognizing
that it's part of the editable.
This PR fixes the issue by making editables slightly more first-class
throughout the resolver. Instead of mocking metadata, we explicitly
check for extras in various places. Part of the problem here is that we
treated editables as URL dependencies, but when we saw an _extra_ like
`attrs[dev]`, we didn't map that back to the URL. So now, we treat them
as registry dependencies, but with the appropriate guardrails
throughout.
Closes https://github.com/astral-sh/uv/issues/1447.
## Test Plan
- Cloned `attrs`.
- Ran `cargo run venv && cargo run pip install -e ".[dev]" -v`.
## Summary
This _could_ fix https://github.com/astral-sh/uv/issues/1454, but I'm
not sure. I was able to replicate by forcing a bunch of error states.
But, in short, if we fail to hardlink on the initial copy due to a file
existing, and then fail _again_, we fallback to copying. But if we copy,
then the tempfile doesn't exist, and so the `fs_err::rename(&tempfile,
&out_path)?;` will fail with "File not found".
This PR just ensures that the cases are explicitly mutually exclusive:
we only attempt to rename if the hardlink succeeded.
This PR fixes the OS detection for Alpine Linux such that the version
of musl available is correctly determined. The issue boiled down to
a regex that required 2 digits for each version component. But a
valid musl version is 1.2.4, which only has a single digit for each
component.
It's unclear how this was working for musl before this change. My
theory is that our other methods of OS detection were somehow working.
The first commit in this PR cleans up our Linux detection logic and adds
lots of tracing calls to make debugging issues like this easier in the
future. To do so, one can run:
$ RUST_LOG=trace uv pip install -v whatever
The second commit has the actual fix.
Fixes#1427
## Summary
By using the display representation of `Version` to form a `PackageId`,
we run the risk (as seen in the linked issue) of thinking that versions
like `2021.1` and `2021.1.0` are not equivalent.
Closes https://github.com/astral-sh/uv/issues/1536
This fixes a bug where `uv pip install` failed to install `polars`:
```
$ uv pip install polars==0.14.0
error: Failed to download: polars==0.14.0
Caused by: Couldn't parse metadata of polars-0.14.0-cp37-abi3-manylinux_2_12_x86_64.manylinux2010_x86_64.whl from 749022b096cb7c1c2cc32b7f433c4f/polars-0.14.0-cp37-abi3-manylinux_2_12_x86_64.manylinux2010_x86_64.whl
Caused by: Operator >= cannot be used with a wildcard version specifier
pyarrow>=4.0.*; extra == 'pyarrow'
^^^^^^^
```
Since `pyarrow>=4.0.*; extra == 'pyarrow'` is invalid *and* it comes
from the metadata of a dependency (that isn't under the control of the
end user), we actually attempt to "fix" it. Namely, wildcard
dependency specifications are only allowed with `==` and `!=`, as per
the [Version Specifiers spec]. (They aren't explicitly forbidden in
these cases, but instead only have specified behavior for the `==` and
`!=` operators.)
This is all fine, but it turns out that when we fix the `>=4.0.*`
component, we also strip the quotes around `pyarrow`. (Because some
dependency specifications include stray quotes.) We fix this by making
our quote stripping a bit more selective. (We require that it appear
adjacent to a digit or a `*`.)
Note that #1477 also reports this error:
```
$ uv pip install 'requests>=2.30.*'
error: Failed to parse `requests>=2.30.*`
Caused by: Operator >= cannot be used with a wildcard version specifier
requests>=2.30.*
```
However, we specifically keep that error message since it's something
under the end user's control. And similarly for a dependency
specification in a `requirements.txt` file.
Fixes#1477
[Version Specifiers spec]:
https://packaging.python.org/en/latest/specifications/version-specifiers/
It turns out that /bin/ls can sometimes be plain text file. For
example, in Rocky Linux 9:
```
$ cat /bin/ls
#!/usr/bin/coreutils --coreutils-prog-shebang=ls
```
However, `/bin/sh` is an ELF binary:
```
$ file /bin/sh
/bin/sh: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=7acbb41bf6f1b7d977f1b44675bf3ed213776835, for GNU/Linux 3.2.0, stripped
```
In a related issue (#1433), @zanieb fixed#1395 where, on NixOS,
`/bin/ls` doesn't exist but `/bin/sh` does. However, the fix attempts
`/bin/ls` first and only tries `/bin/sh` if `/bin/ls` doesn't exist. If
`/bin/ls` exists but isn't a valid ELF file, then the entire enterprise
gives up and `uv` fails to detect the version of `libc` that is
installed.
Instead of tweaking the logic to keep trying `/bin/ls` and then
`/bin/sh` after even if parsing `/bin/ls` fails, we just switch over to
reading `/bin/sh` only. It seems like a more fundamental thing to sniff
and likely less error prone.
We can adjust this heuristic as needed if it provdes to be problematic.
I tested this fix manually on Rocky Linux 9 via Docker:
```
$ cross b -r -p uv --target x86_64-unknown-linux-musl
$ cp target/x86_64-unknown-linux-musl/release/uv ~/astral/issues/uv/i1486/uv
$ docker run --rm -it --mount type=bind,src=/home/andrew/astral/issues/uv/i1486,dst=/host rockylinux:9 bash

Using Python 3.9.18 interpreter at /usr/bin/python3.9
Creating virtualenv at: .venv
[root@df2baa65d2f8 /]#
```
Fixes#1486, Ref #1433
I'm not sure if we should just switch to _always_ reading from sh
instead? I don't love that all these errors are strings and I if
`/bin/ls` exists but can't be parsed we still won't try `/bin/sh`. We
may want to address these things in the future.
Closes https://github.com/astral-sh/uv/issues/1395
## Summary
It looks like `devpi` might add an empty fragment (`#`) at the end of
the URL. We expect it to contain the hash; this just makes
empty-fragment map to "no hash".
Closes https://github.com/astral-sh/uv/issues/1441.
## Summary
If a distribution contains a `+`, it'll be HTML-escaped; so when we try
to identify the `#`, we'll split in the wrong location.
Closes https://github.com/astral-sh/uv/issues/1338.
Closes https://github.com/astral-sh/uv/issues/1388
Fixes incorrect handling of relative paths returned by indexes without
an explicit `<base>`.
`Url.join` will drop the last segment in an url e.g. `http://foo/bar` ->
`http://foo/baz` if there is not a trailing slash but what we want is
`http://foo/bar/baz`. We don't add the trailing `/` in
`base_url_join_relative` because flat indexes are `http://foo/bar.html`
and we _want_ `bar.html` to be replaced.
## Summary
In a `requirements.txt` file, it turns out that the `-c` and `-r`
entries should be interpreted as relative to the file in which they're
declared, while the `-e` entries should be interpreted as relative to
the current working directory, no matter where they're defined.
Previously, we always used the current working directory; now, we use
the declaring file's directory for `-c` and `-r`.

This PR removes the duplication and `DirEntry` internals so that the
error message is easier to grasp:
```
$ uv pip install hexdump==3.3
error: Failed to download and build: hexdump==3.3
Caused by: Failed to extract source distribution
Caused by: The top level of the archive must only contain a list directory, but it contains: ["__main__.py", "hexdump.py", "data", "PKG-INFO", "setup.py", "README.txt"]
```
It's a little picky about the value, but that seems okay.
```

Closes#1382
First, replace all usages in files in-place. I used my editor for this.
If someone wants to add a one-liner that'd be fun.
Then, update directory and file names:
```
# Run twice for nested directories
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
# Update files
find . -type f -print0 | xargs -0 rename s/puffin/uv/g
```
Then add all the files again
```
# Add all the files again
git add crates
git add python/uv
# This one needs a force-add
git add -f crates/uv-trampoline
```
Instead of dropping versions without a compatible distribution, we track
them as incompatibilities in the solver. This implementation follows
patterns established in https://github.com/astral-sh/puffin/pull/1290.
This required some significant refactoring of how we track incompatible
distributions. Notably:
- `Option<TagPriority>` is now `WheelCompatibility` which allows us to
track the reason a wheel is incompatible instead of just `None`.
- `Candidate` now has a `CandidateDist` with `Compatible` and
`Incompatibile` variants instead of just `ResolvableDist`; candidates
are not strictly compatible anymore
- `ResolvableDist` was renamed to `CompatibleDist`
- `IncompatibleWheel` was given an ordering implementation so we can
track the "most compatible" (but still incompatible) wheel. This allows
us to collapse the reason a version cannot be used to a single
incompatibility.
- The filtering in the `VersionMap` is retained, we still only store one
incompatible wheel per version. This is sufficient for error reporting.
- A `TagCompatibility` type was added for tracking which part of a wheel
tag is incompatible
- `Candidate::validate_python` moved to
`PythonRequirement::validate_dist`
I am doing more refactoring in #1298 — I think a couple passes will be
necessary to clarify the relationships of these types.
Includes improved error message snapshots for multiple incompatible
Python tag types from #1285 — we should add more scenarios for coverage
of behavior when multiple tags with different levels are present.
Mostly throwing this up here as a discussion topic. Having something
like this is primarily useful for enabling use cases similar to `rye
add` where I want to use this currently. One can accomplish something
similar with `unearth` today or by abusing regular `pip install`:
```
$ ~/.rye/self/bin/pip install --no-deps --dry-run flask --report - -q | jq '.install[0].metadata | {name, version}'
{
"name": "Flask",
"version": "3.0.2"
}
```
Another option would be to have a `puffin resolve` command or similar
that works like `pip compile` without dependencies, takes the
requirements as arguments and returns a line for each resolution. That
would be a larger change.
This rollbacks the optimization in the previous commit to be more
general. That is, instead of specializing the case of a range for a
singleton version, we make iteration over the distributions in a
`VersionMap` more explicitly lazy. Iteration now provides a `Version`
(like it did previously) and a _handle_ to a distribution that can be
turned into a `ResolvableDist`.
Doing things this way permits callers to iterate over the versions and
only materialize a distribution if they actually need one. In cases like
candidate selection, one can often rule out use of a distribution
through its version alone, and thus skip construction of that
distribution entirely.
In many cases, version ranges are actually just pins to a
specific and single version. And we can detect that statically
by examining the range. If we do have a range that is just one
version, then we can ask a `VersionMap` for just that version
instead of iterating over what's in the map until we find one
that satisfies the range.
I had tried this before making `VersionMap` construction lazy,
but it didn't seem to matter much. But helps a lot more now
with a lazy `VersionMap` because it lets us avoid creating a
lot of distributions in memory that we won't ultimately use.
That is, a `PrioritizedDistribution` for a specific version of a
package is not actually materialized in memory until a corresponding
`VersionMap::get` call is made for that version. Similarly, iteration
lazily materializes distributions as it moves through the map. It
specifically does not materialize everything first.
The main reason why this is effective is that an
`OwnedArchive<SimpleMetadata>` represents a zero-copy (other than
reading the source file) version of `SimpleMetadata` that is really just
a `Vec<u8>` internally. The problem with `VersionMap` construction
previously is that it had to eagerly materialize a `SimpleMetadata` in
memory before anything else, which defeats a large part of the purpose
of zero-copy deserialization. By making more of `VersionMap`
construction itself lazy, we permit doing some parts of resolution
without necessarily fully deserializing a `SimpleMetadata` into memory.
Indeed, with this commit, in the warm cached case, a `SimpleMetadata` is
itself never materialized fully in memory.
This does not completely and totally fully realize the benefits of
zero-copy deserialization. For example, we are likely still building
lots of distributions in memory that we don't actually need in some
cases. Perhaps in cases where no resolution exists, or when one needs to
iterate over large portions of the total versions published for a
package.
This commit adds some logging to candidate selection during
resolution. The idea with these logs is to get a signal on
how much "exploring" the resolver does in specific examples.
For example, this logs helped me realize that at least in
some cases, candidate selection was looking through a long list
of versions even when its range consisted of exactly one
version. We'll use this fact in a later commit.
This makes cloning and thus sharing across multiple threads much
cheaper. Since Tags is conceptually immutable once it is constructed,
this doesn't pose an issue and shouldn't introduce any additional
costs.
This is really annoying, but the snapshots keep changing indentation
when updated.
I could not get insta to update them. So I added a print statement to
`main` and updated the snapshots, then removed the statement and updated
the snapshots again to force them all to refresh.
We use
- An arbitrary ABI hash: `MMMMMM` (six base64 characters)
- An unlikely Jython27 Python tag
For cases that are valid but are never going to be available during
tests.

Moves yanked version filtering from `VersionMap::from_metadata` to the
resolver and tracks it as a PubGrub unavailable incompatibility so
yanked versions are reflected in error messages.
e.g. before
```
╰─▶ Because only albatross<=0.1.0 is available and you require albatross>0.1.0,
we can conclude that the requirements are unsatisfiable.
```
after
```
╰─▶ Because only the following versions of albatross are available:
albatross<=0.1.0
albatross==1.0.0
and albatross==1.0.0 is unusable because it was yanked, we can conclude that albatross>0.1.0 cannot be used.
And because you require albatross>0.1.0, we can conclude that the requirements are unsatisfiable.
```
## Summary
This PR adds an `--offline` flag to Puffin that disables network
requests (implemented as a Reqwest middleware on our registry client).
When `--offline` is provided, we also allow the HTTP cache to return
stale data.
Closes#942.
