Confluent_1.1_Release_Notes

New features/Modified behavior

  • CLI clients now stay 'connected' through a server restart (confetty at prompt or running console).
  • Sensor data is now available (/nodes/<node>/sensors/)</node>
  • Noderanges are (mostly) implemented
    • Can do multi-numbered ranges, e.g. 'r1u1-r10u10', which xCAT can not do
    • Also added pagination: <n skips="" 'n'="" nodes="" into="" the="" range,="">x limits matches to x</n>
    • Implemented in the API tree as '/noderange/' with members that auto-vivify (sort of like automount)
      • /noderange/n1-n8/ (n1 through n8)
      • /noderange/n[1-8]/ (same as above)
      • /noderange/compute@rack1/ (nodes both in compute and rack1)
      • /noderange/rack1,rack2/ (rack1 and rack2, multiple groups)
      • /noderange/compute<50>25/ (skip first 50, show 25 nodes in compute group)
  • Dynamic nodegroups, members defined as a noderange evaluated on the fly
  • xCAT style commands that go straight to confluent (named so as not to conflict)
    • nodepower (like rpower)
    • nodesetboot (like rsetboot)
    • nodeidentify (like rbeacon)
    • nodehealth (new concept, summarize health of nodes)
  • nodesensors offers more powerful tools for gathering data
    • Can specify interval and data points for controlled data collection
    • Can specify csv output
    • Default behavior is similar to 'rvitals'
  • Valid PAM users are no longer allowed unless they also have a /users/ entry in confluent. No password is needed for the entry, password is verified by PAM and not confluent in this mode.
  • stdout/stderr logs now report the source of any data that comes in
  • Set identify LED is implemented
  • node collections are now sorted when enumerated

Fixes

  • Various issues with handling UTF-8 data
  • More robust handling of shellmodule plugins
  • Address some errors that were logged but no failure sent to client
  • nodegroup requests without trailing '/' no longer fail
  • Improved handling of console plugin exceptions
  • Connected client count no longer goes negative
  • Fix confetty behavior when not outputting straight to terminal
  • Confluent no longer fails to work on ppc64
  • More specifically indicate a remote system 'timeout' condition to client
  • HTTP API now tolerates invalid cookies that may leak in from another site in the same domain
  • Configuration change handlers could induce errors to clients that aren't trying to care about the handlers. This is addressed by redirecting those errors to the trace log.
