This page contains notes related to GRASS code migration (planned) from CVS to SVN.

Basic

  • The SVN command line interface is just like CVS, many tasks are identical- just change the program name from cvs to svn.

Gotchas

  • cvs2svn is known to break binary files (images) which were not imported into the CVS with the -kb flag. Luckily Glynn fixed most of these some months ago.
  • Files using keyword substitution, such as $Date$ in the description.html files, will have to have support for that enabled manually, once per file (or write a find routine with | xargs svn ...).
$ svn propset svn:keywords "Date" filename.txt
$ svn commit

or

$ find . -name '*.c' | xargs svn propset svn:keywords "Date" 
$ find . -name '*.html' | xargs svn propset svn:keywords "Date" 
$ svn commit
  • how to maintain timestamps of files? We want to keep the last modification date, not the date of local download
