Pacemaker 2.0.4 - Release Candidate 1

• Features added since Pacemaker-2.0.3

  • build: Add support for glib-based unit tests.
  • controller: add new feature 'shutdown-locks'
    Optionally allow a gracefully shutdown node to have the resources
    locked to it for a configurable time.
    So that it can be restarted with exactly the same resources
    running as before.
  • controller/fencer/scheduler: add new feature 'priority-fencing-delay'
    Optionally derive the priority of a node from the resource-priorities
    of the resources it is running.
    In a fencing-race the node with the highest priority has a certain
    advantage over the others as fencing requests for that node are
    executed with an additional delay.
    controlled via cluster option priority-fencing-delay (default = 0)
  • stonith_admin: add --delay option (default = 0) to support enforced
    fencing delay
  • tools: Add --include= and --exclude= to crm_mon.
  • tools: Add --node= to filter crm_mon output for a node (or tag).
  • tools: Allow more fine grained filtering of fence-history in crm_mon.
  • tools: Allow crm_rule to check some date_specs.

• Changes since Pacemaker-2.0.3

  • build: improve checking headers for C++ fitness
  • build: restore build on latest OpenSUSE
  • libstonithd: Report an error getting history in output instead of
    empty history
  • libstonithd: Improve parameter handling for RHCS-style fence-agents
    - make parameter action shown as not required
  • controller: clear leaving node's transient attributes even if there is no DC
  • controller: don't ack same request twice

  • libcrmcommon, libpe: validate interval specs correctly
  • libcrmcommon: Add pcmk_str_is_infinity, pcmk_str_is_minus_infinity and
    pcmk__unregister_formats.
  • libcrmcommon: Extend what pcmk__split_range can do.
  • libfencing: Export formatted output functions.
  • libpe_status: Add node list arg to output messages preventing weird
    behavior + potential segfaults

  • libstonithd, tools: Fix arguments to stonith-event.
  • scheduler: don't incorporate dependencies' colocations multiple times
  • scheduler: ensure attenuated scores still have some effect
  • scheduler: ignore colocation constraints with 0 score
  • scheduler: make sure cluster-wide maintenance-mode=true overrides
    per-resource settings
  • scheduler: properly detect whether guest node is fenceable
  • scheduler: do not differentiate case where all the nodes have equal priority
  • tests: Add tests for pe_cron_range_satisfied.
  • tests: Add tests for the current behavior of pcmk__split_range.
  • tools, lib: Use standard pacemaker return codes in crm_rule.
  • tools: Correct stonith-event arguments in crm_mon.
  • tools: Fix man pages for crm_mon & crm_diff.
  • tools: Make crm_mon --interval understand more formats.
  • tools: Fix --html-title= in crm_mon.
  • tools: Print errors to stderr for crm_mon's legacy xml.
  • tools: use return codes consistently in stonith_admin
