Subversion edu instructions

How to provide and manage your educational material on osgeo svn
Find out what is there so far: http://svn.osgeo.org/osgeo/education/

Install the svn client software (you may already have it)
Linux:  * 'subversion' package (deb or RPM for your distro, should be on the CDROMs/DVD)

MacOSX: * http://subversion.tigris.org/ -> Downloads

Windows: * http://tortoisesvn.tigris.org/ -> Downloads If you want a pretty graphical user interface, 'TortoiseSVN' integrates nicely with the Windows Explorer.

For a comparison of (graphical user interface and command line) subversion clients, see here.

Checkout the material from the SVN repository into local directory
Command line: svn co http://svn.osgeo.org/osgeo/education/UnderDevelopment/ UnderDevelopment

TortoiseSVN: Just enter this url: http://svn.osgeo.org/osgeo/education/UnderDevelopment/

This will check all the material in UnderDevelopment/ into the local directory UnderDevelopment/

Now add your material....(you need to have commit access - you will be asked for OSGeoID/passwd): cd UnderDevelopment/

If you are just starting, add a directory for your institution (svn add is for adding, but you also need to committ by svn ci)

mkdir MyUniversity svn add MyUniversity svn ci -m "MyUniversity added - some useful comment" MyUniversity

cd MyUniversity create or copy your material here and then add the relevant subdirectories and files to the repository

svn add directory svn ci -m "MyTutorial for beginners added" directory

svn add file svn ci -m "Introduction text added" file

Your group can now work on the material

Before starting the work update to latest version

svn up

Modify/fix/enhance the material and commit the change

svn ci -m "Introduction modified, grammar fixed" file

Brief SVN reference
Help: svn help svn help up   svn help mv    ...

Update from SVN server: svn up

This can happen: A Added D Deleted U Updated C Conflict - ZAP! In this case check for problems G merGed ? file not under version control (e.g. images)

Find out if you have uncommitted changes in your local version: svn status

If no output, everything was uploaded to SVN. Congrats.

Verify changes before submitting: svn diff

Commit changes to SVN server: individual file commit: svn ci -m "Some useful comment" file1 [file2 ...]

or (for global commit of all changes), simply: svn ci -m "Some useful comment"

Add new file/directory to SVN repository: svn add file svn ci -m "Some useful comment" file

svn add directory svn ci -m "Some useful comment" directory

Remove file from SVN server (careful!): svn rm file svn ci -m "Some useful comment" file

Move file to another directory (this is the cool feature of SVN): svn mv file ../some_dir/ cd .. svn ci -m "file moved because ..."

Make new directory (see also svn add above for simplicity): svn mkdir newdirectory svn ci -m "we need a new directory" newdirectory

Oops - submitted a wrong change? Revert! svn revert file

See last changes after updating: (BASE: the revision you updated to, PREV: previous) svn diff -r PREV:BASE svn diff -r PREV:BASE file

Check history of changes (see here for details): svn log file

... on all files: svn log

... create ChangeLog file: svn log > ChangeLog

Handling SVN conflicts (please read the svnbook if unsure!): http://svnbook.red-bean.com/en/1.1/ch03s05.html

Whenever a conflict occurs, three things typically occur to assist you in noticing and resolving that conflict: $ svn commit --message "Add a few more things" svn: Commit failed (details follow): svn: Aborting commit: '/home/sally/svn-work/sandwich.txt' remains in conflict
 * Subversion prints a C during the update, and remembers that the file is in a state of conflict.
 * For every conflicted file, Subversion places up to three extra unversioned files in your working copy
 * At this point, Subversion will not allow you to commit the file until the three temporary files are removed.
 * If you get a conflict, you need to do *one* of three things:
 * Merge the conflicted text 'by hand' (by examining and editing the conflict markers (<<<< >>>>) within the file).
 * or: Copy one of the temporary files on top of your working file.
 * or: Run svn revert to throw away all of your local changes.

Once you've resolved the conflict, you need to let Subversion know by running svn resolved. This removes the three temporary files and Subversion no longer considers the file to be in a state of conflict:

$ svn resolved sandwich.txt Resolved conflicted state of 'sandwich.txt'
