Trying for multi-platform support (wait, again..?)

[goodboy]

Bc new users with fancy hw keep asking about it and i suppose once
we add support the project will prolly get popular with them "career
hackers" with "nice furniture" 😹

Immediately known (now solved) issues,

• our use of XDG_RUNTIME_DIR
  on linux in the UDS tpt backend
  for the selection of the UDSAddress.def_bindspace is problematic.

  • see this SO answer which
    indicates using DARWIN_USER_TEMP_DIR per,

    So the only difference is that Mac doesn't guarantee cleanup on
    log out. (For example, if you're putting a Unix domain socket
    in your runtime directory, when being portable to Mac you can't
    rely on that socket being automatically deleted for you if the
    user logs out but doesn't turn off their computer.)

  • ideally we use some (lib's) cross-platform approach for these
    kinds of problems? I know in the past i've copied
    click.utils.get_app_dir()
    impl for use, but not sure there's an equiv for all $XDG_ style
    vars?

    • SOLVED! with platformdirs in (macOS support (for the fancy peeps with nice furniture) #406) B)

  • SOLVED again via various workarounds in macOS support (for the fancy peeps with nice furniture) #406

    • file-name/path len limits on macos..

    pretty sure @jaredgoldman had a fix for the posix shm
    file-name len problem, but we may have lost that history?
    Either way think a collab has generated a soln with ol claudy
    Bo
    Fix: Shorten shm_list key for osx #341

• we now have Macos in ci #342 !!

Follow through after #406

• there's our outstanding list from long ago ,

• .ipc._shm._shorten_key_for_macos() may cause collisions for short names? #423 as a follow up tracking for symmetric shm-buf-keys
  compared to the linux API.

• we found out we need better daemon fixture syncing support

  • tests.conftest: we need a better daemon syncing approach, prolly via socket polling #424

• the test set should be better oriented around running
  against multiple tpt backends, namely to start 'uds'

  • Run (some) test suites in CI with --tpt-proto uds #422

• the final re-instatement of windows support isn't very
  far off now either B)

  • Windows compatibility fix #408
  • need to get it back in CI as well!
    • Disable win tests in CI #327
