ClearCase UCM - How to get only latest versions from latest baseline

Question

How to get only latest versions from latest baseline -

For example, First time in ClearCase, developers check in for the first time, we would have a.zip, b.zip ; Cl

Answer 1

A baseline references all the files of a component, even if it is incremental.

Using an incremental baseline in a non-UCM snapshot view wouldn't work, because it applies a label only on the elements which are changing (which means the parent directories might not have that label, because they haven't changed, which results in a config spec incapable of selecting the changed files, since said parent directory isn't even selected).

If you are after a view able to show all the latest files, what you can do is:

• a sub-stream ST to stream S which produce those baselines
• a rebase of ST with the latest baseline from S:
  cleartool lsbl -fmt "%[latest_bls]p" -component C -stream S
• a diffbl with the previous baseline, in order to get all the new versions

But you also can:

• list only the changed/new files:
  cleartool diffbl -pred -ver latestBl@\aPVob
• access those files through a dynamic view with the extended pathnames returned by the diffbl -pred -ver command.

That would allow to list/access only the new/changed versions between 'latestBl' and its previous baseline (with latestBl obtained from the lsbl command shown above).
