PMDK Version 2.1.0

This release :

• Introduces the new logging subsystem in the release build for all libraries.
  • Messages by default are printed to syslog and stderr but might be redirected to a user-defined function, see pmem(obj)_log_set_function() for details.
  • Log level thresholds are controlled via new API, see pmem(obj)_log_set_treshold() for details.
  • These new APIs are not available for LIBPMEM2 and LIBPMEMPOOL at the moment.
  • The new logging subsystem is suppressed in the debug build when any of the legacy debug logging environment variables is set:
    • PMEM_LOG_LEVEL_FILE
    • PMEM2_LOG_LEVEL_FILE
    • PMEMOBJ_LOG_LEVEL_FILE
    • PMEMPOOL_LOG_LEVEL_FILE
  • The debug logging subsystem becomes DEPRECATED.
• Introduces fuses against ill-considered use of NDCTL_ENABLE=n.
  • PMEMOBJ_IGNORE_DIRTY_SHUTDOWN and PMEMOBJ_IGNORE_BAD_BLOCKS are required to acknowledge the understanding of what production-critical functions are missing for the build without NDCTL.
• Does not allow create PMEMOBJ pool without unsafe shutdown counter (USC) if not explicitly disabled. (#5968)
  • use PMEMOBJ_CONF="sds.at_create=0" to disable USC when working without PMem (emulated PMem, Docker, etc.).
• Drops support for building without libpthread (NO_LIBPTHREAD build-time define).

PMDK Version 1.13.0

This release:

• Removes (previously deprecated) librpmem. Those interested
  in remote persistent memory support should use the rpma library
  (https://github.com/pmem/rpma).
• Removes libpmemset - it was an experimental library.
• Sets libpmemblk as deprecated, to be removed in the next release.
• Sets libpmemlog as deprecated, to be removed in the next release.
• Sets btt support as deprecated, to be removed in the next release.
• Sets async as deprecated, to be removed in the next release.
• Sets FreeBSD support as deprecated, to be removed in the next release.
• Sets Windows support as deprecated, to be removed in the next release.

Deprecations and removals are done accordingly to the support strategy
outlined in the blog post:
https://pmem.io/blog/2022/11/update-on-pmdk-and-our-long-term-support-strategy.

Other changes and notable bug fixes:

• core: handle ENOMEM gracefully during logging (#5515)
• pool: fix dependencies with pmempool (#5521)
• test: add more security checks for pmempool input
• pmreorder: share markers from an application through env variable (#5419)
• examples: fix potential buffer overflow in pmemobjfs example (#5472)
• several fixes to support ppc64le architecture
• several fixes for issues found by Coverity tool

Known issues:

• The latest validation cycle exposed previously unknown persistency issues
  related to pmem2 async functions (DEPRECATED) and miniasync (EXPERIMENTAL):
  #5596 and #5597. Both will be removed in the PMDK 1.14 release. These issues
  do NOT affect any other PMDK library.
