Merge two branch revisions using Subversion

Question

I'd like to merge all the changes that took place between rev 10 & the HEAD rev on http://url-of-branch-a and apply them to http://url-of-branch-b.

Something like...

svn merge -r 10:HEAD http://url-of-branch-a 

Is this possible? If so, what is the syntax?

I am running the SVN client from the unix command line. The SVN client version is 1.4

EDIT: Yes, my specific solution was...

1. change directory to the location of my working copy that wants to receive the changes (branch-b)
2. svn merge -r 10:HEAD http://url-of-branch-a

This merges the changes from 'branch-a' into 'branch-b'

Answer 1

Mostly confuse merge by trying to do in svn repo, we can not directly merge to svn repo, we can merge to working copy of local machine as follows:

• This working copy should be destination URL of merge(i.e. checkout destination).

• merge working copy with source URL of merge.

• commit to destination.

Best Practice : Merge In , Merge Out.

Answer 2

The process is as follows:

1. Establish a working copy of branch B (svn checkout http://branch-b)
2. Merge changes from branch A into working copy of B (svn merge -r 10:HEAD http://branch-a .)
3. Commit (after resolving conflicts) working copy B to branch b (svn commit)

Check the man page (help file) for svn merge semantics. It shows you that svn merge always dumps the results into a working copy.

Check out the SVNBook for all the details.

Answer 3

Checkout URL A. Use SVN merge to merge URL B to your working copy of A. Commit A.

Or vice versa of course :)
