Why does Clearcase diffbl include activities from

We are using Clearcase UCM and have one Integration stream and each developer has a development stream. When I do a baseline compare, activities from the development stream are sometimes included. Is there any way to get a simple list of activities in the integration stream since a particular baseline?

回答1:

Note: in the integration stream, you will mostly get deliver activities, ie activities recording the merges done during delivers from the development stream.

So if you want activities from two baselines done on the integration Stream, a simple

cleartool diffbl -nmerge -act bl1 bl2

should be enough.
If you somehow see activities from the development stream, that should mean you are comparing bl1 from integration stream with bl2 from a development stream or two baselines from integration with merges, ie with contributing activities.

Hence the –nmerge

Compares two baselines on the same stream and reports only activity and version changes made on that stream.

To illustrate why you see those activities without the -nmerge, see "List the contributing activities in the change set of a baseline or an integration activity"

An activity from the integration Stream will look like this:

Integration activities track work completed as a result of a deliver or rebase operation, and they are named accordingly with a prefix of either deliver or rebase to help distinguish them from user created activities.

If you right-click the activity and select Show Contributing Activities, you will see:

Which is the same than:

 cleartool lsactivity -contrib <deliver baseline>@\pvob

 cleartool lsact -fmt "%[contrib_acts]p" <deliver baseline>@\pvob

Again, the -nmerge option avoids the diffbl to list those contributing activities.

That's because the contributing activities that come from child streams... Try

diffbl -nmerge
