release notes for nbdkit 1.10

Description

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.

New features

  • 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).
