uv pip sync requirements.txt does nothing on 0.2.6 with python_full_version specified

[sterliakov]

With the following requirements.txt:

annotated-types==0.7.0 ; python_full_version >= "3.11.7" and python_full_version < "3.12.0"

(generated by poetry export, with hashes removed manually because they change nothing in this report)

Runnning

uv pip sync requirements.txt

I get

Full repro script:

This repro's with uv 0.2.6 on Ubuntu 22.04 and in docker (public.ecr.aws/docker/library/python:3.11-slim-bookworm). Pinning to 0.2.5 resolves the issue.

This has nothing to do with the specific python versions: requiring

annotated-types==0.7.0 ; python_full_version >= "3.11.6" and python_full_version < "3.12.0"

(so that current version is strictly greater) or even

annotated-types==0.7.0 ; python_full_version < "3.12.0"
# or
annotated-types==0.7.0 ; python_full_version > "3.10.0"

does not help.

I can take a look. Not obvious to me what changed.

Ah ok, it's an issue that's specific to pip sync. pip install should work if you need a workaround. But I will fix it today.
