Merging a release back to the trunk

Example of merging the 1.5 release back to the trunk:

svn merge /Applications/MAMP/htdocs/joomla/trunk

The arguments are svn merge A B C where you want to change A in B and put it in C.

You may like to use the --dry-run option first just to test the command. Merging may take some time. It is a good idea to use the command line to perform this. If you are using Eclipse you will not be able to run this in the background.

See for an explanation of the concepts behind branching and merging.

Breaking a Lock on a File

On occasion you may get an error message like:

 svn: Commit failed (details follow):
 svn: PUT of '/svn/joomla/.../development/trunk/libraries/joomla/application/helper.php':   423 Locked (

To force unlock it remotely, navigate to the correct folder and run the following command:

 svn unlock --force helper.php

See for more information on locking.
