Adding Git repo at subdirectory that points to source in same repo does not work

[Lauszus]

I have a mono repo with two Python packages:

.
├── package1
│   ├── pyproject.toml
│   ├── README.md
│   ├── src
│   │   └── package1
│   │       └── __init__.py
│   └── uv.lock
├── package2
│   ├── pyproject.toml
│   ├── README.md
│   ├── src
│   │   └── package2
│   │       └── __init__.py
│   └── uv.lock
└── README.md

package2 has package1 as a dependency:

dependencies = [
    "package1",
]

[tool.uv.sources]
package1 = { path = "../package1" }

Now create an application that has package2 as a dependency:

mkdir uv-bug
cd uv-bug
uv init
uv add "package2 @ git+https://git@github.com/Lauszus/uv-test.git@main#egg=package2&subdirectory=package2"

This will create a dependency that looks like this:

dependencies = [
    "package2",
]

[tool.uv.sources]
package2 = { git = "https://github.com/Lauszus/uv-test.git", subdirectory = "package2", rev = "main" }

The uv.lock entry for package2 looks fine, as it is pointing to the Git repo:

[[package]]
name = "package2"
version = "0.1.0"
source = { git = "https://github.com/Lauszus/uv-test.git?subdirectory=package2&rev=main#36276098fbaacadf88275f492a457c51c9dffe66" }
dependencies = [
    { name = "package1" },
]

But the source entry for package1 is pointing to the local cache:

[[package]]
name = "package1"
version = "0.1.0"
source = { directory = "../.cache/uv/git-v0/checkouts/64fbda8353baefb8/3627609/package1" }

This means that the CI can not run uv sync it and will fail with something like:

I would expect that it should look something like this:

source = { git = "https://github.com/Lauszus/uv-test.git?subdirectory=package1&rev=main#36276098fbaacadf88275f492a457c51c9dffe66" }

In fact manually changing uv.lock to that makes it work!

A minimal example can be found at:

• https://github.com/Lauszus/uv-bug

Link to successful CI with manually modified uv.lock: https://github.com/Lauszus/uv-bug/actions/runs/12084725612/job/33700499893

My guess is that this is solved by #9388 and is equivalent to #8887?

Yes looks like it. I can test and verify it once #9388 is merged and in a release.

It turns out this is a separate bug, but I'll fix it. Thanks for the clear repro.

Thanks for the quick fix and thanks for uv. It's awesome! :)
