ci(circleci): test Redis behavior against local Redis and print short tracebacks (#44062)
* ci(circleci): test Redis behavior against local Redis and print short tracebacks The redis_caching_unit_tests job ran three legacy files against the shared remote Redis. The DualCache and batch-read logic that never needed a server now lives in tests/unit/caching/test_dual_cache.py with a mocked RedisCache, and the behavior that does need one (the increment-with-floor Lua script, read-through, deletes, batch reads) moved to tests/integration, which starts a local Redis. test_returned_settings only read REDIS_PORT and is replaced by a unit test of Router.get_settings CircleCI pytest runs now use --tb=short so failure output stays readable in the test results tab * ci(integration): print short tracebacks from run.py and allow Redis in the sdk shard |

chore(lint): remove the LIT002 mutable-construction rule (#43971)
* chore(lint): remove the LIT002 mutable-construction rule
Drop LIT002 from scripts/check_type_discipline.py along with its helpers,
its budget entry, its unit tests, and the AGENTS.md and gate docstring
mentions. `# mutable-ok` now only suppresses LIT001, so the markers that
only existed to silence LIT002 became LIT013 stale suppressions and are
removed. The files whose layout depended on those trailing comments are
reformatted with ruff format.
Every other LIT rule count is unchanged and the ASTs of all touched
litellm/ files match main apart from one docstring.
* chore(lint): keep the leftover mutable-ok markers for a follow-up
Restore the ~1.4k `# mutable-ok` markers stripped in the previous commit
so this PR only touches the checker, its tests, the budget, and docs.
Those markers no longer suppress anything, so `# mutable-ok` is exempt
from LIT013 until a follow-up strips them.
* Revert "chore(lint): keep the leftover mutable-ok markers for a follow-up"
This reverts commit
