[Bug 2067361] Re: Programs using netrc with containing an entry without a password fail with an exception "malformed machine entry <> terminated by ''"

[Lucas Kanashiro]

Thanks for the updated patch Eero!

As Dan mentioned, I wouldn't be comfortable sponsoring this upload
without a automated test case. I believe it is a good idea to make sure
the code changes are doing what we expect them to do. The upstream
commit has some tests, couldn't you use some of that in your patch?

Title:
  Programs using netrc with containing an entry without a password fail
  with an exception "malformed machine entry <> terminated by ''"

Status in python3.10 package in Ubuntu:
  Incomplete
Status in python3.10 source package in Jammy:
  New

Bug description:
  Some services use provide token authentication, where the users token is input as the "username" field, resulting in a netrc entry containing
  ```
  machine SOME_ADDRESS
  login SOME_TOKEN
  ```

  but no password entry.

  Trying to run some python based program, that uses netrc, such as
  ```
  ansible-galaxy collection install SOME_PACKAGE
  ```

  with this such a netrc file will fail with an exception
  "malformed machine entry SOME_ADDRESS terminated by ''".

  This is upstream bug https://bugs.python.org/issue34908 fixed in
  python3.11.

  [ Impact ]

   * Users are not able to run Python based programs using netrc
  credentials, such as ansible.

  [ Test Plan ]

   * Install ansible with `sudo apt install ansible`

   * Add an entry to ~/.netrc containing only the "machine" and "login"
  tokens

   * observe failure when trying to run `ansible-galaxy collection
  install community.crypto`

  [ Where problems could occur ]

   * Some over specific test suite relying on current overly strict
  parsing. However such a test suite would have to be fixed for
  python3.11 anyway.
