Getting development information and code history from SVN

• "ChangeLog" style file: install and run ​svn2cl
• File history in SVN:

    cd path/to/directory/
    svn log [file.c]

    # or time reverted:
    svn log [file.c] | tac

• Bug: svn2cl ChangeLog loses file names branch point

Switch the repository

To switch from SVN 'trunk' (now GRASS 7 development) to 'develbranch_6' (now GRASS 6.4 development) use

    cd /path/to/your/local/copy/trunk
    svn switch https://svn.osgeo.org/grass/grass/branches/develbranch_6 .

The switch command preserves local, uncommited changes.

Merge between branches (backporting)

Run the command from within the target branch.

• Example 1: pull a change from trunk into the 6.3 release branch:

      cd releasebranch_6_3/
      svn merge -c 30749 https://svn.osgeo.org/grass/grass/trunk
  

where 30749 is the revision number of the changeset you wish to backport.

• Example 2: merge a change from the 6.4 development branch into GRASS 7 (trunk):

      cd trunk/
      svn merge -c 31154 https://svn.osgeo.org/grass/grass/branches/develbranch_6
