with ClearCase UCM I can create a baseline in a snapshot view directory. When not all files are up-to-date, which version of a file is included in the baseline?

Example: version 3 of foo.txt is located in the snapshot view directory and there already exists a version 4 of this file. Which version of the file is referenced by the baseline?

Does this depends on the version of ClearCase (I am using ClearCase 7.1)? Do I have to consider something?

Background of the question: for a continuous integration build I want to use a snapshot view. When during creating or updating the snapshot view an other user checks in a file to the same stream this new version may or may not be part of the snapshot. At least I want be to be able to identify which files in my snapshot directory have been used by the build.

About Baselines: A mkbl depends on the selection mechanism (the config spec) of the local access mechanism (snapshot or dynamic view) providing said selection mechanism.

For each element in the component, the baseline records the version of that element selected by the stream's configuration at the time mkbl is executed.

So the -view parameter is only there to reference the Stream (and its associated config spec):

-vie/w view-tag

Specifies the view from which to create baselines. Baselines are created in the stream that the view is attached to.

For example, if you are working in coyne_dev_view, but want to create a baseline from the configuration specified by the view coyne_integration_view, use -view coyne_integration_view.
This option creates a baseline in the project's integration stream that includes all the checked-in versions contained in coyne_integration_view.
If you do not specify view-tag, the current view is used.

In your case, if your UCM view is supposed to select v4, but is currently selecting v3 because that snapshot view hasn't been updated yet, the baseline should reference v3 (what is currently selected by the view).

So for your background question, best to perform a cleartool update before the mkbl.
