== Basic ==
== Meta ==


* The SVN command line interface is just like CVS, many tasks are identical- just change the program name from cvs to svn.
* [[SVN_hosting|Where to host the SVN repository?]]
: '''''October 2007: It has been decided to open the SVN at OSGeo'''''


== Gotchas ==
== Basic ==


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

* grass/grass should be renamed to grass/grass5
 
'''Question:'''
* Migrate all directories or only actively used (grass, grass6, newsletter, web)?
* Create separate repositories (grass5, grass6, grassweb, grassnewsletter, grass7) or one repository (grass-svn)?
 
=== Proposed structure ===
 
Note: grass6 was created by copying files from grass5 in 2000. Development of GRASS 7 will start after migration.

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
|
+---/grass

|
+---/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)

|    |
|    +---/tags

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)
