Issue - R27 - Faults and Parallelism in Termination Handlers
Status: received

Date added: 30 Oct 2006

Date submitted: 27 October 2006

Submitter: Dieter Koenig

Description: Consider the following examples of parallelism inside of
termination handlers.

Example 1. Assume that a custom termination handler contains a parallel
forEach activity or a flow activity. In either case, assume that
multiple concurrent branches are active. If one branch faults, the
specification does not tell whether the other branches are allowed to
complete or terminated.

Example 2. Assume that a default termination handler that compensates a
compensation handler instance group. If one compensation handler
instance faults, the specification does not tell whether the other
compensation handler instances are allowed to complete or terminated.

Submitter's proposal: Add the following to the end of section 12.6.:

"If a custom termination handler contains parallel activities and one of
these activities propagates a fault then all concurrent activities in
the termination handler MUST be terminated. Likewise, if a default
termination handler compensates a compensation handler instance group
and one of the compensation handler instances propagates a fault then
the other compensation handler instances of the compensation handler
instance group MUST be terminated."
