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
