3.243.0

Added

• Added auto_queue_splitting option for copy target. Set to true by
  mirrord up command
  to inform the operator that parameters of unsupported queue kinds shall be
  dismissed rather than
  rejected.

Changed

• Connections accepted by the layer now have TCP_NODELAY set to reduce
  latency.
• experimental.guard_std_fds is now enabled by default in OSS (still off by
  default in mfT). #4622

Fixed

• Stolen HTTP requests no longer wait out a retry backoff on a connection the
  local application has already closed. Connections were cached for reuse
  without checking whether they were still open, so a request that drew a
  closed one from the cache failed its first send attempt and waited 50
  milliseconds before making the connection it could have made immediately.
• getaddrinfo calls that pass AI_NUMERICHOST are no longer resolved
  remotely. That flag asks whether the given string is already a numeric
  address rather than for a name lookup, and must fail when it is not, so
  resolving it reported every hostname as a literal address.
