    parameters.
  • fix serialization of the default value of the 'name' parameter in
    the opcodes related to tags when tag kind is 'cluster'
  • revert changes to 'pShutdownTimeout'' and its references because the...

Update Harep, Query server, and tests

Update Harep, Haskell query server, and tests concerning Luxi and
opcodes to reflect the changes to Haskell to Python opcode
generation. This change is necessary because TagObject is replaced by
TagKind and some types in opcodes and parameters changed to be...

Add cleanup parameter to instance failover

Most of the code is shared with instance migrate, so we actually only need
to add the parameter and pass its value along the the common code.

Also, tests and harep are updated to support the right set of options to...

Index instances by their UUID

No longer index instances by their name but by their UUID in the cluster
config. This change changes large parts of the code, as the following
adjustments were necessary: * Change the index key to UUID in the configuration and the...

harep: finish execution with a summary of instance states

The harep tool prints messages for every action that it performs (or that
it doesn't perform). In case nothing is to be done at all, always print
some statistics of the current state of the cluster....

harep: do not wait for repair job completion to set tags

Because of instance locks, after submitting a repair job we weren't able to
set the "pending" tag until at least the first opcode of the job finished.
Introduce a small delay in the repair job so as to allow the subsequent...

harep: create repair jobs

Implement 'doRepair' to create a repair job from a list of opcodes if
the instance's policy allows it (otherwise set an ENOPERM result label),
and the instance was previously healthy (i.e. not in ArFailed or
ArPendingRepair).

harep: pure function to detect brokeness with instances

Add a 'detectBroken' function that determines whether an instance is in an
unhealthy state, and what's needed to repair it. The repair is specified as
an AutoRepairType constant, and a list of opcodes. The opcodes will only be...

harep: check for completed jobs at the start of the program

As a first step before detecting any brokeness with instances, see if any
of our previous repairs have completed, and move instances to ArFailed or
ArHealthy accordingly. Do nothing if there are still running jobs for the...

harep: initial parsing of tags

Parse auto-repair tags to set each instance in one of ArHealthy, ArFailed,
or ArPendingRepair. The implementation tries to be well behaved when old
tags have been left behind, which future patches will still try not to do....
