I am new clearcase I am trying to rebase the branch m_tool. Could you please tell me how should i go about rebasing for the following config spec?

element * CHECKEDOUT
element * DATASOURCE
element /entities/... /main/LATEST 
element * .../m_tool/LATEST 

mkbranch m_tool
element * .../branch2011/LATEST 
element * TAG_2010_OCT_02
element * .../m_dd_lt_hfix/LATEST 
element * TAG_2010_02_DEV_BASE
element * /main/LATEST 
end mkbranch m_tool

Thank you, Dennis

"Rebasing" is a merge between a parent UCM stream and a direct child Stream.

What you show is a base ClearCase config spec, not an UCM one.

That config spec would show the latest on m_tool branch, and, for version which haven't yet any m_tool branch:

  • the latest of branch2011
  • or, if no branch2011, the tag TAG_2010_OCT_02
  • or if no tag TAG_2010_OCT_02, the latest of branch m_dd_lt_hfix
  • or, if no branch m_dd_lt_hfix, the tag TAG_2010_02_DEV_BASE
  • or, as a stop rule, the latest of main branch

In each case, if a version is done, you would create it on the m_tool branch.

If that is what you mean by "rebasing", then it is correct.

I want m_tool to have everything, instead of looking at each tags/branch.

Then you would need to merge a view which display only non m_tool versions:

element * .../branch2011/LATEST 
element * TAG_2010_OCT_02
element * .../m_dd_lt_hfix/LATEST 
element * TAG_2010_02_DEV_BASE
element * /main/LATEST

And merge that view an m_tool-only view:

element * .../m_tool/LATEST 
element * /main/0 -mkbranch m_tool
element * /main/latest -mkbranch m_tool

  • Hi VonC, Thanks for your explanation. I want m_tool to have everything, instead of looking at each tags/branch. Do you know how is it done? Thank you, Dennis – dwong Nov 13 '13 at 18:50
  • @DennisWong Then possibly do a merge of non-m_tool versions into an m_tool view. I have edited my answer. – VonC Nov 13 '13 at 19:46
  • Hi VonC,I don't quite understand the concept of stop rule. Can you please explain a little more? I saw the link you have attached. – dwong Nov 13 '13 at 21:11
  • @DennisWong a stop rule is a selection rule that will *always* be used, because there is *always* a `/main` branch, and *always* at least one version (the version 0). So any rule you put *after* that `element * /main/LATEST` will *always* be *ignored*, because the selection process *stopped* at the "stop rule". – VonC Nov 13 '13 at 22:00
  • I just tried to rebase each branch and tag one by one. I got an error saying that this config spec only support branch to brach rebase. Do you happen to know why? Thanks! – dwong Nov 14 '13 at 01:31
  • @DennisWong what do you mean "rebase"? Are you actually using UCM? Can you edit your question with a screenshot of the error? – VonC Nov 14 '13 at 06:12
