nbdkit-release-notes-1.10 - release notes for nbdkit 1.10

These are the release notes for nbdkit stable release 1.10. This describes the major changes since 1.8.

nbdkit 1.10.0 was released on 18th January 2019.

  • Implemented "NBD_FLAG_CAN_MULTI_CONN" which greatly improves performance for clients that support it.
  • Implemented "NBD_OPT_INFO" (Eric Blake).
  • nbdkit-data-plugin(1) and nbdkit-memory-plugin(1): By adding fine-grained locking, these plugins now use the fully parallel thread model.
  • nbdkit-cache-filter(1): The size of the cache can now be limited, and the cache reclaims space using an LRU algorithm. It has also been enhanced to support cache-on-read mode. The filter now uses a fully parallel thread model.
  • nbdkit-cow-filter(1): Use a fully parallel thread model.
  • nbdkit-sh-plugin(1): Inline scripts: https://rwmj.wordpress.com/2018/12/15/nbdkit-inline-scripts/
  • nbdkit-sh-plugin(1): Full API version 2 is now supported.
  • nbdkit-ocaml-plugin(3): Full API version 2 is now supported.
  • nbdkit-delay-filter(1) allows you to specify the read, write, zero and trim delays individually.
  • nbdkit-curl-plugin(1): Add support for connecting to servers over Unix domain sockets.
  • Bash tab completion has been improved: Partial plugin names are expanded correctly, and plugin parameters containing "-" work.
  • Public header files can now be consumed by ISO C90 compilers (but GCC or Clang is still required to compile nbdkit itself).
  • A better non-cryptographically secure pseudo-random number generator (xoshiro256** 1.0) is now used on all platforms, replacing previous uses of random(3).
  • Fuzzing using American Fuzzy Lop is now supported, and was carried out, resulting in one error being found in the server (not security related).
  • New nbdkit-xz-filter(1): This replaces nbdkit-xz-plugin which will be removed in nbdkit 1.12.
  • New nbdkit-loop(1) man page documenting how to use nbdkit for loop mounts. See also: https://fosdem.org/2019/schedule/event/nbdkit/
  • New nbdkit-full-plugin(1): Returns "ENOSPC" on every request.
  • "attribute((format))", "attribute((nonnull))" and "attribute((sentinel))" are used in internal header files to improve code quality.
  • Logging using %m now works on all platforms, not just on Linux with glibc (Eric Blake).
  • VPATH builds partially supported (Eric Blake).
