Pull request overview
This PR aims to reduce redundant I/O syscalls in the async host ledger implementation by relying on atomic exclusive file creation and skipping an unnecessary truncate in some cases.
Changes:
- Replace pre-create
fs::exists()check with exclusive-createfopen(..., "x")and explicitEEXISThandling. - Skip
truncate()duringcomplete()when the ledger file is considered “fresh” (notfrom_existing_file).
