This is a small expansion on an earlier post about svn merging.
The svn Red Book gives the typical scenarios for merging including supporting work in development branches.
Create the branch:
svn cp https://svnserver.com/app/trunk https://svnserver.com/app/development
Check it out
svn co https://svnserver.com/app/development
Do work and keep the local copy updated based on updates to branch, trunk
blah svn up svn merge [--dry-run] ^/trunk
Commit changes (including those merged from trunk
When done, merge back to trunk, delete branch, remake branch
svn merge [--dry-run] --reintegrate ^/branches/development svn ci svn delete ^/branches/development svn cp https://svnserver.com/app/trunk https://svnserver.com/app/branches/new-development
In chapter 4 of the RedBook is a section called “Reintegrating” where the authors discuss why one should delete the development branch (and if necessary recreate it).
