Comparing two baselines in RTC / Jazz with plain java
I am trying to compare two snapshots from the same stream programmatically in simple java ...
Step 1: getting my thread (working)
IWorkspaceConnection stream = null;
List<IWorkspaceConnection> list = RtcAdapter.inst().getStreams(); //my library
for (IWorkspaceConnection connection: list){
if (connection.getName().equalsIgnoreCase("myStreamName") ){
stream = connection;
break;
}
}//now we have found our stream
Step 2: get baselines (working)
List<IBaselineSet> snapShotList =
RtcAdapter.inst().getSnapShotsFromStream(stream);
IBaselineSet snapShot0 = null;
IBaselineSet snapShot1 = null;
for (IBaselineSet snapShot: snapShotList){
if (snapShot.getName().equalsIgnoreCase("mySnapShotName0") ){
snapShot0 = snapShot;
}
if (snapShot.getName().equalsIgnoreCase("mySnapShotName1") ){
snapShot1 = snapShot;
}
}//now we've got also my two snapShots
Step 3: comparing each other (doesn't work)
IUpdateReport report =
workspaceManager.compareBaselineSetConfigurations(
snapShot0, snapShot0, stream.getComponents(), monitor);
my report is empty ... --annoying -
report=com.ibm.team.scm.common.internal.dto.impl.UpdateReportImpl@1de5a20 (stateBefore: <unset>, stateAfter: <unset>)
I also tried to get ChangeHistorySyncReport ...
IChangeHistorySyncReport report =
workspaceManager.compareBaselineSets(
snapShot0, snapShot1, componentList(stream), monitor);
also the report is empty ...
so how do i generate the correct report? or how can I compare the two original lines? (what am I doing wrong?
report.getAffectedComponents()
returns an empty array as well report.getModifiedComponents()
UPDATE as far as I know, now I have to check ChangeHistorySyncReport ... and when I print my report it says:
com.ibm.team.scm.common.internal.dto.impl.ChangeHistorySyncReportImpl@150f091 (localTime: <unset>, remoteTime: <unset>, compareFlags: <unset>)
this makes my question deeper - how can I set a better CompareFlags?

GOD it took me ages ...
but first first: it was perfectly correct to use IChangeHistorySyncReport
instead
IUpdateReport
...
so what happened?
IWorkspaceConnection stream; //is not null, already instantiated somewhere else
IBaselineSet bl0 = (IBaselineSet)
itemManager.fetchCompleteItem(baseLineHandle0, IItemManager.DEFAULT, monitor);
IBaselineSet bl1 = (IBaselineSet)
itemManager.fetchCompleteItem(baseLineHandle1, IItemManager.DEFAULT, monitor);
IChangeHistorySyncReport report =
workspaceManager.compareBaselineSets(bl0, bl1, getComponentHandles(stream), monitor);
simple code change solves the problem
//have a close look: 3.rd param is now null!!
IChangeHistorySyncReport report =
workspaceManager.compareBaselineSets(bl0, bl1, null, monitor);
By the way, there was another tricky part when I looked at the report:
System.out.println("report: "+report );
System.out.println("incoming: "+report.incomingChangeSets() );
output:
report = com.ibm.team.scm.common.internal.dto.impl.ChangeHistorySyncReportImpl@127c1ae (localTime: <unset>, remoteTime: <unset>, compareFlags: <unset>)
incoming []
looked empty at first glance - but digging deeper I found out that I was just asking report.outgoingChangeSets()
, which gives out a large amount of (expected) changes ...
but when I exchange the baseline workspaceManager.compareBaselineSets(bl1, bl0, null, monitor);
then
-
report.outgoingChangeSets()
empty and -
report.incomingChangeSets()
brings the right results!
update:
using the compare-compare method, I can now ensure full scatter across multiple components.
