java - 将 RTC/Jazz 中的两个基线与纯 Java 进行比较

Question

我尝试在纯 Java 中以编程方式比较来自一个流的两个快照...

第 1 步:获取我的流(工作)

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

第 2 步:获取基线(工作)

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

第三步:相互比较(无效)

IUpdateReport report = 
    workspaceManager.compareBaselineSetConfigurations(
        snapShot0, snapShot0, stream.getComponents(), monitor);

我的报告是空的... --烦人--

report=com.ibm.team.scm.common.internal.dto.impl.UpdateReportImpl@1de5a20 (stateBefore: <unset>, stateAfter: <unset>)

我还尝试获取 ChangeHistorySyncReport...

IChangeHistorySyncReport report = 
    workspaceManager.compareBaselineSets(
        snapShot0, snapShot1, componentList(stream), monitor);

报告也是空的...

那么我该如何创建一个合适的报告呢？或者我如何比较两个基线？ (我做错了什么？

report.getAffectedComponents()返回一个空数组，report.getModifiedComponents() 也是如此

更新据我所知，我现在必须检查 ChangeHistorySyncReport... 当我打印我的报告时，它说:

com.ibm.team.scm.common.internal.dto.impl.ChangeHistorySyncReportImpl@150f091 (localTime: <unset>, remoteTime: <unset>, compareFlags: <unset>)

这让我的问题更深了 - 我怎样才能设置更好的 CompareFlags？

Answer 1

上帝我花了很长时间....

但首先要做的是:使用 IChangeHistorySyncReport 而不是IUpdateReport...

那到底是哪里出了问题？

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);

只需更改代码即可解决问题

//have a close look: 3.rd param is now null!!
IChangeHistorySyncReport report = 
    workspaceManager.compareBaselineSets(bl0, bl1, null, monitor); 

顺便说一句，还有一个棘手的部分，当我浏览报告时:

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 []

乍一看是空的 - 但深入挖掘后我发现我只需要请求 report.outgoingChangeSets() 即可带来大量(预期的)变化...

但是当我交换基线时 workspaceManager.compareBaselineSets(bl1, bl0, null, monitor); 然后

• report.outgoingChangeSets() 为空且
• report.incomingChangeSets() 带来正确的结果!!

更新:

使用比较基线方法，我现在可以提供多个组件的完整差异!!!
