AI Summary

This release introduces a change to file handle semantics to prevent failures when re-opening closed files, although it invalidates duplicate references. It also refines logging metrics to better track cache performance.

Key Highlights

  • Fixed issue where re-opening a closed file would fail
  • Duplicate references to closed file handles are now invalidated
  • Added cache hit rate metrics to logs
  • Added cache metrics for OTLP export
  • Refined and removed redundant cache metrics

Breaking Changes

  • Re-opening a file after closing now succeeds and triggers deferred uploads if required, but duplicate references to the old handle become invalid and operations on them will fail

New Features

  • Cache hit rate tracking in logs
  • Cache metrics for OTLP export

Full Release Notes

### Breaking changes

* Address an issue where opening a file for reading/writing immediately after the file had been closed would occasionally fail. Since this release, opening a new file handle after close will succeed and trigger the completion of a deferred upload if required. As a consequence, duplicate references to the closed file handle will become invalid and read or write operations on them will fail. See [this section in the semantics documentation](https://github.com/awslabs/mountpoint-s3/blob/main/doc/SEMANTICS.md#close-and-re-open) for details. ([#1704](https://github.com/awslabs/mountpoint-s3/pull/1704))
