Duocomm support in channel performance and view change tests
------------------------------------------------------------
Key: HEDERA-43
URL: https://forge.continuent.org/jira/browse/HEDERA-43
Project: Hedera
Type: Sub-task
Versions: Hedera 2.0
Reporter: Linas Virbalas
Assigned to: Robert Hodges
Duocomm semantics and configuration are a little different from JGroups and
Appia. We need to make the Hedera ViewChangeTest and
ChannelPerformanceMultiprocessTest to pass with Duocomm. Currently Duocomm
supports only 2 members, because of this we need to make at least 2 member
tests to pass:
ChannelPerformanceMultiprocessTest.testChannelPerformanceMultiprocess1 - 2
members
ChannelPerformanceMultiprocessTest.testChannelPerformanceMultiprocess2 - 4
members
ChannelPerformanceMultiprocessTest.testChannelPerformanceMultiprocessLong - 2
members
ViewChangeTest.testViewChange() - 2 members
ViewChangeTest.testViewChangeSafetyConditions() - 2 members
ViewChangeTest.testVirtualSynchrony() - 4 members
Changes needed:
1. Ability to pass a separate config file for every member. Duocomm specifies
the binding address with port in it, so we need to specify different addresses
for the members. E.g.:
-Dproperties=/hedera_duocomm0.properties:/hedera_duocomm1.properties
2. Make the ViewChangeTestThread.waitAllMembersToJoin() react to the
groupComposition(...) event. We need this because Duocomm sends
groupComposition event instead of the joinMember in some cases.
3. Wait for a master to join in the testViewChangeSafetyConditions. Duocomm
takes its time when a first member joins (not an issue with JGroups and Appia
though). We'll add a ViewChangeTestThread.waitSelfToJoin() method for that.
