nativelink-store/src/filesystem_store.rs line 583 at r1 (raw file):
let from_path = encoded_file_path.get_file_path(); // Internally tokio spawns fs commands onto a blocking thread anyways. // Since we are already on a blocking thread, we just need the `fs` wrapper to manage
maybe spell out std::fs::rename.
Given its the std::fs::rename it manages open-file permit (via FnOnce) or is the call_with_permit missing here?
nativelink-util/src/fs.rs line 246 at r1 (raw file):
/// Acquire a permit from the open file semaphore and call a raw function. #[inline] pub async fn call_with_permit<R>(func: impl FnOnce() -> Result<R, Error>) -> Result<R, Error> {
Defined but not used?

In a rare case where a file is uploaded, but while the rename() function is called the future is dropped the filesystem store can get into a bad state. fixes: #495
