Zanie Blue	3000a47fe8	Include file permissions in key for cached files (#5901) ... Reimplements https://github.com/astral-sh/ruff/pull/3104 Closes https://github.com/astral-sh/ruff/issues/5726 Note that we will generate the hash for a cache key twice in normal operation. Once to check for the cached item and again to update the cache. We could optimize this by generating the hash once in `diagnostics::lint_file` and passing the `u64` into `get` and `update`. We'd probably want to wrap it in a `CacheKeyHash` enum for type safety. ## Test plan Unit tests for Windows and Unix. Manual test with case from issue ``` ❯ touch fake.py ❯ chmod +x fake.py ❯ ./target/debug/ruff --select EXE fake.py fake.py:1:1: EXE002 The file is executable but no shebang is present Found 1 error. ❯ chmod -x fake.py ❯ ./target/debug/ruff --select EXE fake.py ```	2023-07-25 17:06:47 +00:00
Thomas de Zeeuw	1c638264b2	Keep track of when files are last seen in the cache (#5214) ... ## Summary And remove cached files that we haven't seen for a certain period of time, currently 30 days. For the last seen timestamp we actually use an `u64`, it's smaller on disk than `SystemTime` (which size is OS dependent) and fits in an `AtomicU64` which we can use to update it without locks. ## Test Plan Added a new unit test, run by `cargo test`.	2023-06-23 15:40:35 +02:00
Thomas de Zeeuw	17f1ecd56e	Open cache files in parallel (#5120) ... ## Summary Open cache files in parallel (again), brings the performance back to be roughly equal to the old implementation. ## Test Plan Existing tests should keep working.	2023-06-20 17:43:09 +02:00
