RE: Strange behavior

Thanks for the quick merge lesson. I would need to use the same directory for the branch as the trunk since there is a rather large infrastructure required to run the project (It is an ERP application). So I would plan on using switch. As long there are no hidden gotchas I should be OK.

You're overthinking this. You can use OS level commands to trim down the files to import. Copy the files to a temp directory, delete the files you don't want imported, and then run 'svn import' on the tmp dir. Even if you have mistakes in the import, you can use 'svn rm' and 'svn add' to clean things up.

It would be nice if you could pass 'svn import' a list of filenames/regexes to include or exclude, but modern shells already have the tools to filter and delete files, so there's little need to add those wheels to 'svn import'. Especially since the import is normally a one-time event.

Are you using 'svn import' multiple times? (Such as to create additional branches of the code?) If so, that would be bad, as in wrong paradigm/workflow.

As for branching, here's the short version for the 1.8 svn client:
0) Use 'svn import' to create the initial baseline, say /trunk.
1) Create the branch: 'svn copy svn:/server/trunk svn:/server/branches/foo.2.0.0'
2) Create branch workspace: cd /myworkspaces && svn co svn:/server/branches/foo.2.0.0' && cd foo.2.0.0

3) Work on foo.2.0.0
3.1) 'svn add' to add new files (svn:ignore will help here.)
3.2) 'svn ci' to commit the files
3.2) Periodically merge trunk changes up to foo.2.0.0: svn merge ^/trunk
    Note: makes sure your foo.2.0.0 changes are checked in before merging up from trunk, 'svn status'

When foo.2.0.0 is "done", first merge trunk up to foo.2.0.0 to make sure that foo.2.0.0 has the current trunk changes
4) 'svn merge ^/trunk'
4.1) Resolve any conflicts.

Now merge foo.2.0.0 down to trunk.
5) Create a clean merge workspace
    cd /myworkspaces && 'svn co svn:/server/trunk' && cd trunk
    Note: if you are reusing a workspace, then 'svn status' and 'svn update' to make sure it's clean and ready for a merge.
6) 'svn merge ^/branches/foo.2.0.0'
6.1) Resolve any conflicts.
7) 'svn ci'
