How to create a branch in svn?

Question

subversion

There is a classic repository: trunk, branches, tags. You need to create a new branch from the trunk. I create a new directory mybranch in branches. I make svn copy https://svn.adv.ru/svn/project/trunk https://svn.adv.ru/svn/project/branches/mybranch. After that, the trunk directory itself appears in mybranch along with the contents, and in theory there should be only the contents of the trunk. What am I doing wrong?
Question 2: in further development, when changes occur in the trunk, will they be automatically uploaded to mybranch upon checkout, or do I need to merge trunk changes into mybranch myself?

Answer 1

The catalog did not need to be created. You can do it through svn copy or even svnmucc cp without creating a working copy.
I won’t write an example with svnmucc right away. With SVN 1.7, if I'm not mistaken, you can use the ^ character to indicate the root of the repository instead of the full URL when specifying the path.
After creating a branch, nothing will be automatically merged, you need to do it manually every time.
