Add `--dry-run` flag to `uv pip install` #1436

JacobCoffee · 2024-02-16T05:42:24Z

What

Adds a --dry-run flag that ejects out of the installation process early (but after resolution) and displays only what would have installed

Closes

Closes #1244

Out of Scope

I think it may be nice to include a dry-run flag for uninstall even though pip doesn't implement this... thinking Would uninstall X packages: ...

JacobCoffee · 2024-02-16T07:17:43Z

Sorry if this is a bad way to get the version? It felt bad, anyway...
I'm not sure if we do or can store version at resolution time and use it in dry_run, install, validate, etc.

JacobCoffee · 2024-02-16T07:41:27Z

Might be cool to have a dry-run flag for uninstalling although not native to pip

crates/uv/src/commands/pip_install.rs

JacobCoffee · 2024-02-16T07:59:08Z

On the failing CI, I had some failures do to order in stdout there... but I'm wondering how we keep it consistent?

zanieb · 2024-02-17T04:24:59Z

Hey @JacobCoffee, thanks for the pull request! I think we'll actually want to implement this a bit differently e.g. by passing the dry run flag into install

uv/crates/uv/src/commands/pip_install.rs

Line 477 in 896ab1c

async fn install(

then we can use our existing display which will also show which versions we would remove (and has a sorting implementation for deterministic output)

uv/crates/uv/src/commands/pip_install.rs

Line 642 in 896ab1c

for event in reinstalls

We'll just need to tweak the install function to avoid doing any downloads, uninstalls, builds, or installs when the flag is set.

zanieb · 2024-02-22T02:13:38Z

I'll give this a try tomorrow!

zanieb · 2024-02-23T00:28:23Z

Hey! I got a chance to play with this today. I'm thinking we should match our normal output much more closely.

I put up a commit for you to build off of at #1890

We still need more test coverage i.e. install a dependency of a package first then dry run install what do we show? or install an old version then dry run install with --upgrade

JacobCoffee · 2024-02-25T19:46:19Z

Just for my notes, i am running into an issue where in testing it passes with 2 $package==$version, but in CLI usage i get 4 ====

➜ ./target/debug/uv pip install litestar==2.0.0 --dry-run --strict
Resolved 17 packages in 974ms
Would download 2 packages
Would install 17 packages
 + anyio====4.3.0
 + litestar====2.0.0
 + faker====23.2.1
 + fast-query-parsers==1.0.3

But removing the == printer config from the +/- sections remove it from the testing :|

zanieb · 2024-02-28T18:35:10Z

@JacobCoffee I'm on vacation this week but let me know when this is ready for review again

JacobCoffee · 2024-03-01T03:54:25Z

sorry ive not wrapped this - i think my remaining issue is the 4 ====, but ive just had surgery so im down for a bit on my hard thinking 😅

zanieb · 2024-03-03T03:35:50Z

I can give it a look! Get better :)

zanieb · 2024-03-04T23:10:28Z

The issue is that InstalledVersion which comes from cached distributions includes == already (fixed by fee46b3).

I believe this is redundant as it is handled before this function is called

## Summary This proposes adding the command line option `uv pip uninstall --dry-run ...`, complementing the existing `uv pip install --dry-run ...` added for #1244 in #1436. This option does not exist in PyPA's `pip uninstall`, if adopted it would be unique to `uv pip`. The code should be considered PoC, it is baby's first Rust. The initial motivation was while investigating moreati/ansible-uv#2 - to allow Ansible module `moreati.uv.pip` to work with`state: absent` in "check_mode" (Ansible's equivalent of a dry run), without requiring `packaging` or `setuptools`. ## Test Plan One new unit test has been added. I pedge to add more if the feature is desired/accepted Example usage ```console ➜ uv git:(pip-uninstall--dry-run) rm -rf .venv ➜ uv git:(pip-uninstall--dry-run) ./target/debug/uv venv Using CPython 3.13.0 Creating virtual environment at: .venv Activate with: source .venv/bin/activate ➜ uv git:(pip-uninstall--dry-run) ./target/debug/uv pip install httpx Resolved 7 packages in 178ms Prepared 5 packages in 60ms Installed 7 packages in 15ms + anyio==4.6.2.post1 + certifi==2024.8.30 + h11==0.14.0 + httpcore==1.0.7 + httpx==0.28.0 + idna==3.10 + sniffio==1.3.1 ➜ uv git:(pip-uninstall--dry-run) ./target/debug/uv pip uninstall --dry-run httpx Would uninstall 1 package - httpx==0.28.0 ➜ uv git:(pip-uninstall--dry-run) ./target/debug/uv pip list Package Version -------- ----------- anyio 4.6.2.post1 certifi 2024.8.30 h11 0.14.0 httpcore 1.0.7 httpx 0.28.0 idna 3.10 sniffio 1.3.1 ``` --------- Co-authored-by: Charlie Marsh <charlie.r.marsh@gmail.com>
