How to change a revision message

1) First we change the log message in the GiBUU repository. For this we go to the workingCode directory and type

svn propset --revprop -r "revisionNumber" svn:log "new log message"

Alternatively one can specify a file which contains the new log message:

svn propset --revprop -r "revisionNumber" svn:log -F some_file.txt

2) Now an admin (!!) needs to resync the TRAC project. For this purpose he logs in tp11 and goes to the /srv/www/htdocs/tracProject directory and types

trac-admin GiBUU resync
