RE: Rolling back some components of a tag

Hi Erik

Thanks for your reply.

svn merge http://host/trunk -c -1859 .

The trouble is that this will bring in all changes at r1859, not just those made to pegtest.txt. I realise that in my example there are no other changes but I am looking for the general case.

Is there any other way of changing the revision of one file in a branch, where that revision has not existed in the branch before?

It has been suggested that I use peg revisions to solve this problem. However, I don't understand peg revision syntax.

As a test, I created a new text file in the trunk called pegtest.txt and then made changes to it:

r1855 commit pegtest.txt ver.1
r1856 commit pegtest.txt ver.2
r1857 commit pegtest.txt ver.3
r1858 create tag of trunk
r1859 commit pegtest.txt ver.4
r1861 create branch of tag
r1862 commit pegtest.txt ver.5

Now if I look at my branch, pegtest.txt is ver.3 i.e. r1857 as expected.

If, in my branch, I do:

svn update -r1856 pegtest.txt
I'm still on old subversion not having caret-functionality so I would do (in the branch):
svn merge http://host/trunk -c -1859 .
svn ci -m"reverted [1859] from branch"

pegtest.txt gets deleted. I guess this is because the branch did not exist in r1856.

How can I use a PEG revision to bring pegtest.txt r1856 from the trunk into the branch please?
