Fix some circular deps:
- move PromptValue into top level module bc both PromptTemplates and
OutputParsers import
- move tracer context vars to `tracers.context` and import them in
functions in `callbacks.manager`
- add core import tests
My thought is that the ==version would prevent pip from finding the
package on regular [pypi.org](http://pypi.org/), so it would look at
[test.pypi.org](http://test.pypi.org/) for that. Otherwise it'll pull
package from [pypi.org](http://pypi.org/) (e.g. sub deps)
Right now, the cli release is failing because it's going to
test.pypi.org by default, so it finds this incorrect FASTAPI package
instead of the real one: https://test.pypi.org/project/FASTAPI/
The new ruff version fixed the blocking bugs, and I was able to fairly
easily us to a passing state: ruff fixed some issues on its own, I fixed
a handful by hand, and I added a list of narrowly-targeted exclusions
for files that are currently failing ruff rules that we probably should
look into eventually.
I went pretty lenient on the docs / cookbooks rules, allowing dead code
and such things. Perhaps in the future we may want to tighten the rules
further, but this is already a good set of checks that found real issues
and will prevent them going forward.
PyPI trusted publishing wants to know which workflow is expected to do
the publish. We always want to publish from the same workflow, so we're
making `_test_release.yml` the only workflow that publishes to Test
PyPI.
This follows the principle of least privilege. Our `poetry build` step
doesn't need, and shouldn't get, access to our GitHub OIDC capability.
This is the same structure as I used in the already-merged PR for
refactoring the regular PyPI release workflow: #12578.
Best to review one commit at a time, since two of the commits are 100%
autogenerated changes from running `ruff format`:
- Install and use `ruff format` instead of black for code formatting.
- Output of `ruff format .` in the `langchain` package.
- Use `ruff format` in experimental package.
- Format changes in experimental package by `ruff format`.
- Manual formatting fixes to make `ruff .` pass.
Before making a new `langchain` release, we want to test that everything
works as expected. This PR lets us publish `langchain` to test PyPI,
then install it from there and run checks to ensure everything works
normally before publishing it "for real".
It also takes the opportunity to refactor the build process, splitting
up the build, release-creation, and PyPI upload steps into separate jobs
that do not share their elevated permissions with each other.
Adds a `langchain-location` param to lint, so we can properly locate it.
Regular langchain and experimental lint steps are passing, so default
value seems to be working.
