## Summary
Allow using http(s) urls for constraints and requirements files handed
to the CLI, by handling paths starting with `http://` or `https://`
differently. This allows commands for such as: `uv pip install -c
https://raw.githubusercontent.com/apache/airflow/constraints-2.8.1/constraints-3.8.txt
requests`.
closes#1332
## Test Plan
Testing install using a `constraints.txt` file hosted on github in the
airflow repository:
fbdc2eba8e/crates/uv/tests/pip_install.rs (L1440-L1484)
## Advice Needed
- filesystem/http dispatch is implemented at a relatively low level (at
`crates/uv-fs/src/lib.rs#read_to_string`). Should I change some naming
here so it is obvious that the function is able to dispatch?
- I kept the CLI argument for -c and -r as a PathBuf, even though now it
is technically either a path or a url. We could either keep this as is
for now, or implement a new enum for this case? The enum could then
handle dispatch to files/http.
- Using another abstraction layer like
https://docs.rs/object_store/latest/object_store/ for the
files/urls/[s3] could work as well, though I ran into a bug during
testing which I couldn't debug
## Summary
Follow up from discussion in https://github.com/astral-sh/uv/pull/2223
Detect CMD.exe by checking if `PROMPT` env var is set on windows,
otherwise assume it's PowerShell.
Note, this will not work if user modifies their system env vars to
include `PROMPT` by default or if they launch nested PowerShell from
Command Prompt (e.g. `Developer PowerShell for VS 2022`).
## Test Plan
Only tested locally, although we try to add some CI tests that
specifically use CMD.exe

## Summary
Implementation for https://github.com/astral-sh/uv/issues/1594
The output will contain only the name, version and location of the
packages for now but it should be extendable to include other
information in the future.
Quite inexperienced with Rust, so please forgive me if there are things
that obviously don't make sense 😭
## Test Plan
Added a bunch of unit tests. The exit code behavior matches `pip`'s
behavior:
- When the package is found -> exit code 0
- When the package isn't found -> exit code 1
- When one package is found but another isn't -> exit code 0
Implements `pip list --format=freeze` and `pip list --format=json`
Closes https://github.com/astral-sh/uv/issues/1970
## Test Plan
Extended existing `pip list` tests to match output.
Need to look at escaping in the Windows test 🪟
## Summary
`pip` uses `sysconfig` for Python 3.10 and later by default; however, it
falls back to `distutils` for earlier Python versions, and distros can
actually tell `pip` to continue falling back to `distutils` via the
`_PIP_USE_SYSCONFIG` variable.
By _always_ using `sysconfig`, we're doing the wrong then when
installing into some system Pythons, e.g., on Debian prior to Python
3.10.
This PR modifies our logic to mirror `pip` exactly, which is what's been
recommended to me as the right thing to do.
Closes https://github.com/astral-sh/uv/issues/2113.
## Test Plan
Most notably, the new Debian tests pass here (which fail on main:
https://github.com/astral-sh/uv/pull/2144).
I also added Pyston as a second stress-test.
## Summary
This PR migrates our virtualenv creation from a setup that assumes prior
knowledge of the correct paths, to a technique borrowed from
`virtualenv` whereby we use `sysconfig` and `distutils` to determine the
paths. The general trick is to grab the expected paths with `sysconfig`,
then make them all relative, then make them absolute for a given
directory.
Closes#2095.
Closes#2153.
## Summary
This makes `--python python3` and `--python 3.10` more consistent on
Windows.
Closes https://github.com/astral-sh/uv/issues/2213.
## Test Plan
Ran `cargo run venv --python python3.12` with the Windows Store Python.
## Summary
We have logic in `python_query.rs` to filter out Windows Store shims
when you use invocations like `-p 3.10`, but not `--python python3`,
which is uncommon but allowed on Windows.
Closes#2211.
## Summary
Our Windows shim detection wasn't catching shims like `python3.12.exe`.
Closes#2208.
## Test Plan
Installed Python 3.12 via the Windows Store; verified that `cargo run
venv --python 3.12` failed before but passes after this change.
## Summary
When determining "direct" dependencies, we need to ensure that we
respect markers. In the linked issue, the user had an optional
dependency like:
```toml
[project.optional-dependencies]
dev = [
"setuptools>=64",
"setuptools_scm>=8"
]
```
By not respecting markers, we tried to resolve `setuptools` to the
lowest-available version. However, since `setuptools>=64` _isn't_
enabled (since it's optional), we won't respect _that_ constraint.
To be consistent, we need to omit optional dependencies just as we will
at resolution time.
Closes https://github.com/astral-sh/uv/issues/2203.
## Test Plan
`cargo test`
Follow-up to #2086: Don't use timeouts for the entire workers, but only
for the section that's about communicating with the (potentially broken)
`python` subprocess. I've also raised the timeout to 60s.
Add a `--compile` option to `pip install` and `pip sync`.
I chose to implement this as a separate pass over the entire venv. If we
wanted to compile during installation, we'd have to make sure that
writing is exclusive, to avoid concurrent processes writing broken
`.pyc` files. Additionally, this ensures that the entire site-packages
are bytecode compiled, even if there are packages that aren't from this
`uv` invocation. The disadvantage is that we do not update RECORD and
rely on this comment from [PEP 491](https://peps.python.org/pep-0491/):
> Uninstallers should be smart enough to remove .pyc even if it is not
mentioned in RECORD.
If this is a problem we can change it to run during installation and
write RECORD entries.
Internally, this is implemented as an async work-stealing subprocess
worker pool. The producer is a directory traversal over site-packages,
sending each `.py` file to a bounded async FIFO queue/channel. Each
worker has a long-running python process. It pops the queue to get a
single path (or exists if the channel is closed), then sends it to
stdin, waits until it's informed that the compilation is done through a
line on stdout, and repeat. This is fast, e.g. installing `jupyter
plotly` on Python 3.12 it processes 15876 files in 319ms with 32 threads
(vs. 3.8s with a single core). The python processes internally calls
`compileall.compile_file`, the same as pip.
Like pip, we ignore and silence all compilation errors
(https://github.com/astral-sh/uv/issues/1559). There is a 10s timeout to
handle the case when the workers got stuck. For the reviewers, please
check if i missed any spots where we could deadlock, this is the hardest
part of this PR.
I've added `uv-dev compile <dir>` and `uv-dev clear-compile <dir>`
commands, mainly for my own benchmarking. I don't want to expose them in
`uv`, they almost certainly not the correct workflow and we don't want
to support them.
Fixes#1788Closes#1559Closes#1928
## Summary
We have at least one reported case of this happening. It's preferable
IMO to move on rather than fail hard despite sub-pbar registry behavior.
Closes https://github.com/astral-sh/uv/issues/2099.
## Summary
This will make it easier to use the paths returned by `distutils.py`
(for some cases). No code or behavior changes; just removing some fields
we don't need.
## Summary
Closes#1977
This allows us to send uv's version in the `uv-client` User Agent
header.
Here's how request headers look like to a server now:
```
...
Accept: application/vnd.pypi.simple.v1+json, application/vnd.pypi.simple.v1+html;q=0.2, text/html;q=0.01
User-Agent: uv/0.1.13
...
```
~~I went for a mix of Option 1 and 2 from #1977.~~ Open to alternative
naming as well, not tied too strongly here to the names picked.
~~Another possibility for this new crate is that we can use it to
consolidate metadata that exists across crates to ultimately be able to
create linehaul information described in #1958, but I haven't looked
into what those changes might look like.~~
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
<!-- How was it tested? -->
Added initial tests in the new crate to exercise its public API and
added a new test to uv-client to validate the headers using a 1-time
disposable server.
## Summary
Ensures that local dependencies function similarly to editables, in that
if they're `uv pip install`ed, we invalidate them.
Closes https://github.com/astral-sh/uv/issues/1651.
## Summary
Internal-only refactor to consolidate multiple codepaths we have for
checking whether a cached or installed entry is up-to-date with a local
requirement.
Error for `uv pip compile scripts/requirements/jupyter.in` without
internet:
**Before**
```
error: error sending request for url (https://pypi.org/simple/jupyter/): error trying to connect: dns error: failed to lookup address information: No such host is known. (os error 11001)
Caused by: error trying to connect: dns error: failed to lookup address information: No such host is known. (os error 11001)
Caused by: dns error: failed to lookup address information: No such host is known. (os error 11001)
Caused by: failed to lookup address information: No such host is known. (os error 11001)
```
**After**
```
error: Could not connect, are you offline?
Caused by: error sending request for url (https://pypi.org/simple/django/): error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution
Caused by: error trying to connect: dns error: failed to lookup address information: Temporary failure in name resolution
Caused by: dns error: failed to lookup address information: Temporary failure in name resolution
Caused by: failed to lookup address information: Temporary failure in name resolution
```
On linux, it would be "Temporary failure in name resolution" instead of
"No such host is known. (os error 11001)".
The implementation checks for "dne error" stringly as hyper errors are
opaque. The danger is that this breaks with a hyper update. We still get
the complete error trace since reqwest eagerly inlines errors
(https://github.com/seanmonstar/reqwest/issues/2147).
No test since i wouldn't know how to simulate this in cargo test.
Fixes#1971
## Summary
This PR expands environment variables in `-r` and `-c` paths _within_
requirements files. We already do this for `@` URL references and
others.
Closes https://github.com/astral-sh/uv/issues/1473.
## Summary
After https://github.com/astral-sh/uv/pull/2121, the only remaining
issue is that calling `canonicalize` on these Pythons returns an error.
Closes https://github.com/astral-sh/uv/issues/2105.
## Test Plan
Uninstalled all python.org Pythons on my Windows machine, then created a
virtualenv. The resulting config file:
```
Using Python 3.11.8 interpreter at: C:\Users\crmar\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.11_qbz5n2kfra8p0\python.exe
Creating virtualenv at: .venv
Activate with: .venv\Scripts\activate
PS C:\Users\crmar\workspace\puffin> cat .\.venv\pyvenv.cfg
home = C:\Users\crmar\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.11_qbz5n2kfra8p0
implementation = CPython
version_info = 3.11.8
include-system-site-packages = false
uv = 0.1.13
prompt = puffin
```
Prior to this PR, it would fail with a canonicalization error.
Prior to #2121, it would leave a "bad" Python in the config file:
```
Using Python 3.11.8 interpreter at: C:\Users\crmar\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.11_qbz5n2kfra8p0\python.exe
Creating virtualenv at: .venv
Activate with: .venv\Scripts\activate
PS C:\Users\crmar\workspace\puffin> cat .\.venv\pyvenv.cfg
home = C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.11_3.11.2288.0_x64__qbz5n2kfra8p0
implementation = CPython
version_info = 3.11.8
include-system-site-packages = false
uv = 0.1.13
prompt = puffin
```
Which, once activated, would fail with:
```
(venv) PS C:\Users\crmar\workspace\puffin> python
No Python at '"C:\Users\crmar\AppData\Local\Programs\Python\Python312\python.exe'
```
## Summary
When I install via the Windows Store, `interpreter.base_prefix` contains
a bunch of resolved information that leads to a broken environment.
Instead, we now use `sys._base_executable` on Windows by default,
falling back to `sys.base_prefix` if it doesn't exist. (There are some
issues with `sys.base_executable` that lead to complexity in
`virtualenv`, but they only affect POSIX.) Admittedly, I don't know when
`sys._base_executable` wouldn't exist. It exists in all the environments
I've tested.
Additionally, we use the system interpreter directly if we're outside of
a virtualenv.
## Summary
Closes#2012
This changes `RequirementsTxtParserError::Parser` to take a line, column
instead of cursor location to improve reporting of parser errors. A new
function was added to compute the line and column based on the content
and cursor location when a parser error occurs for simplicity.
Given `uv pip compile .\requirements.txt` of below
```
numpy>=1,<2
--borken
tqdm
```
Before:
```
error: Unexpected '-', expected '-c', '-e', '-r' or the start of a requirement in `.\requirements.txt` at position 14
```
After:
```
error: Unexpected '-', expected '-c', '-e', '-r' or the start of a requirement in `.\requirements.txt` at position 2:3
```
Open Question: Do we want to support `line:column` for other types of
errors? I didn't look dig other potential error types where this might
be desired.
## Test Plan
New test was added to `requirements-txt` crate with this example.
## Summary
It looks like these have been included since the very first gourgeist
commit, but `virtualenv` and `venv` don't include them, and they only
add complexity AFAICT.
## Summary
I think Camino is nice but it makes it much harder to work in
`uv-virtualenv`, since it's the _only_ crate that uses it. If we want to
use Camino, we should use it everywhere IMO.
