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.
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.
See https://github.com/zanieb/packse/pull/109
In the scenario tests, we want to make sure we're actually conforming to
the scenario's expectations, so we now have an extra assertion on
whether resolution failed or succeeded as well as that it includes the
given packages.
Closes#1112Closes#1030
Replaces https://github.com/astral-sh/puffin/pull/1068 and #1070 which
were more complicated than I wanted.
- Introduces a `.python-versions` file which defines the Python versions
needed for development
- Adds a Bash script at `scripts/bootstrap/install` which installs the
required Python versions from `python-build-standalone` to `./bin`
- Checks in a `versions.json` file with metadata about available
versions on each platform and a `fetch-version` Python script derived
from `rye` for updating the versions
- Updates CI to use these Python builds instead of the `setup-python`
action
- Updates to the latest packse scenarios which require Python 3.8+
instead of 3.7+ since we cannot use 3.7 anymore and includes new test
coverage of patch Python version requests
- Adds a `PUFFIN_PYTHON_PATH` variable to prevent lookup of system
Python versions for isolation during development
Tested on Linux (via CI) and macOS (locally) — presumably it will be a
bit more complicated to do proper Windows support.
e.g. for scenarios that test resolution _without_ installation.
This refactors the `update` script to generate scenario test files for
`pip compile` _and_ `pip install`. We don't overlap scenarios to save
time. We only generate `pip compile` test cases for scenarios we cannot
represent with `pip install` e.g. a `--python-version` override.
The _one_ scenario I added happened to reveal a bug in our resolver
where we were incorrectly filtering versions by the installed version
when wheels were available. Per the comment at
https://github.com/astral-sh/puffin/issues/883#issuecomment-1890773112,
we should _only_ need to check for a compatible installed Python version
when using a different _target_ Python version if we need to build a
source distribution.

resolves this by removing the excessive constraints — the correct Python
version incompatibilities are applied elsewhere.
Uses new metadata added in https://github.com/zanieb/packse/pull/61 to
assert that resolution succeeded or failed _and_ that the installed
package versions match the expected result.
Previously, we just pulled the latest commit from `main` on every
update. This causes problems when you do not intend to update the
scenarios as in #787.
This bumps to the latest `packse` commit without new scenarios.
Following #757, improves the script for generating scenario test cases
with:
- A requirements file
- Support for downloading packse scenarios from GitHub dynamically
- Running rustfmt on the generated test file
- Updating snapshots / running tests
