James Bardin	bfa6ab4617	Fix removeEdge test failures ... The removeEdge test could fail intermittently with the wrong order. The precondition of a 1->2->3 order wasn't met, because there was no edge from 1->3, so 3->1->2 was also a valid ordering. The other failure was a bookkeeping error, were the recorded order may not match the visited order. What happened in this case was the gateCh was closed by V2, allowing V3 to run which could beat V2 to recording its visit. Now the visit is recorded as part of the vertex walk, and the gate is released as the final operation. The order is deterministic now, so remove the brute-force test loop.	9 years ago
James Bardin	d01b0b0647	Remove intermittent failure from newEdge test ... Because the vertex visit was record after the Update call, Updated vertices may have been visited before the visit was recorded, causing occasional test failures. The order is now deterministic, and we can remove the brute-force loop.	9 years ago
James Bardin	7bf33c2a7f	Remove loop from TestWalker_removeVertex ... There's no timing dependent behavior here, since V1 must be visited before V2, Remove and Update must be called before V2 is visited.	9 years ago
James Bardin	0fb24c1a7a	Remove sleep-based concurrency from newVertex test ... Add a synchronization channel for the TestWalker_newVertex test, rather than using a sleep and running it multiple times.	9 years ago
