chore: Update redis-py<7 & python >= 3.9

[nsteinmetz]

• redis-py 6.x was released
  • redis-py 6.x covers all current supported version of redis and had some breaking changes - so 6.x is the new minimal requirement.
  • Removed the _disconnect_case related test as it no longer exists in redis-py
• python 3.8 is EOL
• Added python 3.13
• Bump dependencies versions

@samuelcolvin what is the strategy / best way to upgrade versions of components ? Such as ruff or pydantic-core ?

Fixed ✅

[nsteinmetz]

I don't know how to fix this one:

❯ make mypy             
mypy arq
arq/connections.py:104: error: Missing type parameters for generic type "ConnectionPool"  [type-arg]
arq/connections.py:244: error: Argument "sentinels" to "Sentinel" has incompatible type "str | list[tuple[str, int]]"; expected "Iterable[tuple[str, int]]"  [arg-type]
arq/connections.py:249: error: Redundant cast to "ArqRedis"  [redundant-cast]
arq/worker.py:873: error: "ArqRedis" has no attribute "aclose"  [attr-defined]
arq/worker.py:914: error: "ArqRedis" has no attribute "aclose"  [attr-defined]
Found 5 errors in 2 files (checked 12 source files)

Fixed ✅

@samuelcolvin : please review the changes, I'm not sure about all of them.

Due to all changes, it may be worth bumping to 0.27 ?

[nsteinmetz]

@JonasKs @samuelcolvin after reading #437 - is this PR worth ?

[nsteinmetz]

@JonasKs @samuelcolvin my previous comment is one month old - could you please comment and provide feedback so that we can know what we can expect on arq side ?

[skoolboar]

Can somebody take a look at this???
