Subject: unexpected tree conflict on merge for same source file
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

Hello,

imagine the following repository structure:

/branches/prj1/first.txt
/branches/prj1/second.txt
/branches/prj2/first.txt
/branches/testing/first.txt
/branches/testing/second.txt
/trunk/first.txt

All first.txt in /branches/* are from the same /trunk/first.txt
The file was only changed in /trunk and synced in /branches/prj1/

prj1 was merged into testing

Why is there a tree conflict when I try to merge prj2 into testing? It
is the same file.

Below is a .bat file for creating the repo with some more conflicts that
we do not understand. I would be happy if someone could explain these as
well.


What I try to achieve with the additional testing branch is to have some
kind of staging before going live.

The idea is to do this for new features:
1. Create branch from the latest live system /(trunk)
2. Work on branch
3. Merge branch into testing system (/branches/testing)
4a If everything is ok merge into /trunk and delete branch
4b If something is wrong return to 2.

Best regards
Sven.
