This release:

  • Enables unsafe shutdown and bad block detection on Linux
    on systems with libndctl >= 63. It is expected that systems with
    libndctl >= 63 has necessary kernel support (Linux >= 4.20).
    However, due to bugs in libndctl = 63 and Linux = 4.20, it is
    recommended to use libndctl >= 64.1 and Linux >= 5.0.4.
    On systems with libndctl < 63, PMDK uses old superuser-only
    interfaces. Support for old or new interfaces is chosen at BUILD
    time.
  • Introduces arena control interface in pmemobj, allowing applications
    to tweak performance and scalability of heap operations. See
    pmemobj_ctl_get man page ("heap" namespace) for details.
  • Introduces copy_on_write mode, which allows testing applications
    using pmemobj with pmreorder. See pmemobj_ctl_get man page
    ("copy_on_write" namespace) for details.

Other changes:

  • allocate file space when creating a pool on existing file
    (pmem/issues#167)
  • initial support for testing using fault injection
  • initial Python test framework
  • improve performance of pmemobj_pool_by_ptr

Bug fixes:

  • common: work around tmpfs bug during pool creation
    (pmem/issues#1018)
  • pool: race-free pmempool create --max-size
  • obj: don't modify remote pools in pmemobj_check
