Using latest version of FastAPI, it refuses to start and wants to be
re-installed via pip. This does not seem right?


# dpkg -l | grep fastapi
ii  python3-fastapi                 0.115.5-2                   all
      modern, fast, web framework for building APIs, based on type
hints

# which fastapi
/usr/bin/fastapi

# fastapi version
To use the fastapi command, please install "fastapi[standard]":
pip install "fastapi[standard]"
Traceback (most recent call last):
  File "/usr/bin/fastapi", line 8, in <module>
    sys.exit(main())
             ^^^^^^
  File "/usr/lib/python3/dist-packages/fastapi/cli.py", line 12, in main
    raise RuntimeError(message)  # noqa: B904
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^
RuntimeError: To use the fastapi command, please install "fastapi[standard]":
pip install "fastapi[standard]"

This looks like a missing dependency on fastapi-cli (unpackaged)

https://github.com/fastapi/fastapi-cli

Both packages declare an entrypoint script for fastapi; the one in the
fastapi package doesn't seem useful for Debian.

regards
Stuart

Ah, see https://github.com/fastapi/fastapi/discussions/11525 for why
fastapi-cli was moved to a separate package, so avoid having fastapi
depend on such a large set of packages.

So as Stuart Prescott points out in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1090781#10
it would make more sense for these dependencies to be part of a new
fastapi-cli package and to drop the /usr/bin/fastapi command from
python3-fastapi.

Best wishes,

   Julian

closing #1093046 as there's nothing to be done for src:fastapi, and
even if there was, no optional dependency belongs in the Depends
field, but instead in the Recommended/Suggests fields depending on
their importance in the optional features they enable when present.

We believe that the bug you reported is fixed in the latest version of
fastapi, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1090781@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Changes:
 fastapi (0.141.1-2) unstable; urgency=medium
 .
   * debian/control
     - bump debhelper compat to 14; add dh-sequence-python3 and
       dh-sequence-single-binary to b-d
     - drop the manual Depends on pydantic and starlette, and the substvars;
       dh_python3 generates the versioned dependencies from the upstream
       metadata
     - bump versioned b-d on pydantic, starlette and typing-extensions to the
       upstream minimums; add versioned b-d on annotated-doc and
       typing-inspection
     - drop aiofiles, aiosqlite, databases, passlib, peewee and requests from
       b-d, no longer needed by tests
     - add sqlalchemy to b-d, needed by tests and previously pulled in by
       databases
     - drop Priority, optional is now the default
     - bump Standards-Version to 4.7.4.1 (no further changes needed)
     - point Homepage to the new upstream location
     - fix the bullet list formatting in the long description; drop the
       outdated minimum Python version
   * debian/rules
     - drop --with python3, replaced by dh-sequence-python3
     - run test_response_by_alias, test_root, test_async_testing,
       test_dependency_gets_exception and test_path_operation_img, now passing
     - install the upstream changelog; patch by Julian Gilbey; Closes: #1093472
     - don't install the fastapi command, it requires fastapi-cli which is not
       available in Debian; Closes: #1090781
   * debian/pybuild.testfiles
     - install favicon.png at the path expected by test_path_operation_img;
       the docs/en/docs/img/ entry was not copying anything
   * debian/python3-fastapi.pyremove
     - remove the .agents directory, containing the upstream AI agent skill
   * debian/source/options
     - remove, pdm-backend doesn't generate egg-info
   * debian/copyright
     - update upstream source URL; add stanza for termynal; extend packaging
       copyright years
   * debian/watch
     - convert to version 5, using the GitHub template
   * debian/upstream/metadata
     - update to the new upstream location; add Changelog and Documentation
