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


== Gotchas ==
* [[SVN_hosting|Where to host the SVN repository?]]
: '''''October 2007: It has been decided to open the SVN at OSGeo'''''


* 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.
== Basic ==


* 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 ...).
* The SVN command line interface is just like CVS, many tasks are identical - just change the program name from cvs to svn.
$ svn propset svn:keywords "Date" filename.txt
$ svn commit
 
* how to maintain timestamps of files? We want to keep the last modification date, not the date of local download

Migrate all directories or only actively used (grass, grass6, newsletter, web)?

NOTE 2008: The migration has be done - this page is archived for historical reasons

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

Meta

October 2007: It has been decided to open the SVN at OSGeo

Basic

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

GRASS CVS repository structure

/grass-cvs
|
+---/grass
|
+---/grass51
|
+---/grass6
|
+---/grass_doc
|
+---/libgrass
|
+---/newsletter
|
+---/programgrass50
|
+---/web

GRASS OSGeo SVN repository structure

See Discussion page for details. 

/grass-svn
|
+---/grass
|    |
|    +---/trunk (grass6 CVS HEAD)
|    |
|    +---/branches
|    |    |
|    |    +---/releasebranch_5_x (note: 5_5 based on grass5 CVS HEAD)
|    |    |
|    |    +---/releasebranch_6_x
|    |
|    +---/tags
|
|---/grass-addons
|
+---/grass-web
|    |
|    +---/trunk

Notes:

  • grass51, grass_doc, libgrass and programgrass50 are dead, will be not migrated
  • grass migrated as grass/branches/releasebranch_5_5
  • web migrated as grass-web
  • newsletter will be merged with OSGeo newsletter repository
  • wxPython GUI moved from grass-addons to grass code base (grass/gui/wxpython)
  • gui/wxpython/screenshots removed, can be part of grass-addons (e.g. grass-addons/screenshots/wxpython)

For text files are used keywords=Author Date Id Revision, in detail:

SVN hosting

There are two main options to host the new SVN repository.
