PMDK Version 1.8-rc1

PMDK Version 1.8-rc1

PMDK Version 1.7

This release:

• Introduces new APIs in libpmemobj for managing space used by transactions.
  (see pmemobj_tx_log_append_buffer man page for details)
• Introduces new APIs in librpmem, splitting rpmem_persist into rpmem_flush
  and rpmem_drain, allowing applications to use the flush + drain model
  already known from libpmem. (libpmemobj does not use this feature yet)
• Optimizes large libpmemobj transactions by significantly reducing
  the amount of memory modified at the commit phase.
• Optimizes tracking of libpmemobj reservations.
• Adds new flags for libpmemobj's pmemobj_tx_xadd_range[_direct] API:
  POBJ_XADD_NO_SNAPSHOT and POBJ_XADD_ASSUME_INITIALIZED, allowing
  applications to optimize how memory is tracked by the library.

To support some of the above changes the libpmemobj on-media layout had
to be changed, which means that old pools have to be converted using
pmdk-convert >= 1.7.

Other changes:

• obj: fix merging of ranges when NOFLUSH flag is used (pmem/issues#1100)
• rpmem: fix closing of ssh connection (pmem/issues#995, pmem/issues#1060)
• obj: abort transaction on pmemobj_tx_publish failure

Internal changes:

• test: fault injection tests for pmemblk, pmemlog, and pmemobj
• test: improved Python testing framework
• test: support real pmem in bad blocks tests
• common: allow not building examples and benchmarks

PMDK Version 1.6

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
