Yes. The difference was because of caching. I forgot to mention that. This is due to the way our CI image docker optimisation works
The way how the image is constructed is that it first installs dependencies from https://github.com/apache/airflow to save on any future re-installs - using docker caching mechanism (it works the same for `pip` and `uv pip`. It works roughly like this: LAYER 1: pip install "apache-airflow[devel-ci] @ https://github.com/apache/airflow/archive/main.tar.gz <- here we install all airflow dependencies in the main AT THE MOMENT THIS LAYER WAS BUILT LAYER 2: COPY pyproject.toml LAYER 3: pip install ".[devel-ci]" --constraints https://..... It is a very nice way of caching and speeding up adding new dependencies I introduced years ago that works very nicely for us for remote builds (so local breeze builds are making use of it as well) - this means that ALL dependencies of airflow will be pre-installed as a cached layer in the image, regardless of modification in pyproject.toml. So whenever someone modifies pyproject.toml and adds new dependencies or modifies the existing ones - LAYER 1 will NOT be invalidated, but LAYER 2 (and LAYER 3) will - which means that the LAYER 3 pip install will only install new dependencies (and it will use latest constraints for that). LAYER 1 is only modified when: a) Python base image changes (every few weeks) b) Docker scripts change (those scripts that are COPIED before that layer - so for example airlfow installation scripts). c) DEPENDENCY_EPOCH change -> we can manually bump it to force the reinstallation after we remove some dependency, to make sure it is regenerated This has the side effect that when you add or modify a dependency, it is very fast - instead of reinstalling all 600+ dependencies, they are already installed and you only get dif Another side effect of it that the image (between Python base image updates or epoch/docker script changes) is that the image gets ever so bigger - every time new constraints are update and cache rebuilt and constraints updated, the image gets updated with new dependencies in main, incrementally adding changed (and only those changed ones) dependencies in LAYER 3. So I was comparing an image where LAYER 1 was created some time ago with pip (and LAYER 3 got bigger) with pretty much "From the scratch" image where LAYER 1 was "latest deps" and LAYER 3 has almost no updated/ new dependencies. That explains the difference. The new image will also get slightly bigger in the next few days or weeks, until a new Python base image is released or we will update the scripts. Also - all tests pass and that's most important. The CI image is exclusively used to run tests, it's not used in production. The production image is still using `pip` (I had some problems with PROD image building with uv - because it expects virtualenv. rather than --user installation of ours) . We might want to fix it some time in the future (and uv might add it as a feature in the meantime) - let's give `uv` some time to settle :). So - it has no impact on the user-facing side (at all). Re: dependencies after `uv` was successful have been updated here: https://github.com/apache/airflow/commit/fd64235a481adb4aaff1b2f432eaceb9d0b5c53c in our constraints 2 hrs ago. As you can see - the changes are "as expected" - there are a few dependencies bumped since yesterday (correctly picked up by uv --highest resolution mechanism). The `uv pip freeze` command of uv for now uses original, non-canonical names of packages - but the original now (underscores instead of dashes) - but that's perfectly fine, those packages get canonical names. This will likely get changed in the future. J.
