[FIXED JENKINS-27708][FIXED JENKINS-27871] Ensure that identification of
blocked tasks is using the live state.
- The creation of a snapshot itself should be relatively cheap given the
expected rate of
job execution. You probably would need 100's of jobs starting execution every
iteration
of maintain() before this could even start to become an issue and likely the
calculation
of isBuildBlocked(p) will become a bottleneck before updateSnapshot() will.
Additionally
since the snapshot itself only ever has at most one reference originating
outside of the stack
it should remain in the eden space and thus be cheap to GC.
- JENKINS-27708 comments 225819 and 225906 provide more complex but logically
equivalent fixes of
this issue. I am favouring this approach as it is simpler and provides less
scope for error as any
new helper methods can just rely on the snapshot being up to date whereas
with the other
two candidates if a new helper method is introduced there is the potential to
miss adding support
for the live view. The comment 225819 has the risk of introducing extra lock
contention while
the comment 225906 version forces every access to the helper methods to pass
a second memory
barrier
