How to update the property for all member baseline

问题:

We have composite baseline for our components.

Whenever we release the product after recommend the baseline, I would change the property of baseline to change the promotion level.

By default the promotion level is "INITIAL".
While we release the product i would change the Promotion property as "EXTERNAL RELEASE".

But to do this, I have to go and edit each any every member baseline property.
Is there any way to make changes in composite baseline properties to replicate in it's member?

回答1:

No, the re is no "inheritance" between the custom values of a composite baseline and its baseline member.

It is best to script the operation, by describing the composite baseline, extract the baseline members name, and do a cleartool mkattr -replace on each one with the new value.
(cleartool mkattr has a -recurs - recursive - option, but it would be for directory only, it doesn't work for non-file-system objects)

cleartool descr -fmt "%[depends_on]Cp\n" aCompositeBaseline@\aPVob
# for each member baselines
cleartool mkattr -replace PromotionLevel "EXTERNAL RELEASE" baseline:aBaseline@\aPVob

Note how I use the fully qualifed name of the object on which I want to modify the custom attribute value: baseline:aBaseline@\aPVob.

Since "EXTERNAL_RELEASE" isn't a default promotion level, you need to define it first: see "About creating custom promotion levels and attribute types for UCM baselines".
