ClearCase：如何使用分支类型创建分支

Question

I'm trying to use mkbranch command to create branch from main/abc branch.

I create branch type with following command:

mkbrtype –c "bugfix branch from abc" bugfixAbc

Now I need to create branch with that branch type.

How I'll create new branch from main/abc branch with branch type bugfixAbc?

Answer 1

You need to modify your config spec in order to create new versions starting from abc . see for example " Where do new elements appear when mkelem is used? ":

element * CHECKEDOUT
element * .../bugfixAbc/LATEST
element * .../abc -mkbranch(bugfixAbc)
element * /main/0 -mkbranch(bugfixAbc)
element * /main/LATEST

The ellipsis .../ in a selection rule allows for ClearCase to select that branch abc , from whatever branch it comes from: /main , or any other branch.

Using cleartool mkbranch is not the solution here: it won't scale if you have to do it for many files, and it creates a version 0 left in checked-out state, that you should checkin. (or cancel the checkout, which would delete the branch)

By using a config spec, you will create automatically that branch each time you checkout an element present in the abc branch. Any element, not just a given file.

Answer 2

I find out that I can give the path of the file like this:

mkbranch -c "bugfix branch from abc" bugfixAbc util.java@@/main/abc/27

So, this created branch from abc branch with branch type bugfixAbc
