[Javabdd-devel] Moving joeq/JavaBDD/bddbddb from CVS to Subversion

[John W. <joe...@gm...>]

Hello all,

Now that Sourceforge has Subversion support, I'm planning to move the
Java project repositories on Sourceforge from using CVS over to
Subversion.

Subversion is better that CVS in just about every possible way.  First
of all, actions on a repository are atomic.  Second, it supports
operations like renames and copies natively.  Third, it does a much
better job of working disconnected.  Fourth, with Subversion there is
no more lag between the anonymous and developer repositories.  Fifth,
it communicates using the standard https port rather than the ssh
port, so it is more firewall-friendly.  Sixth, the Eclipse Subversion
plugin (Subclipse) appears to allow you to use both the command-line
'svn' command and the Subversion commands from the UI, whereas Eclipse
CVS was incompatible with the command line 'cvs' command.  And the
list goes on and on...

The downsides to switching over to Subversion are that everyone will
have to check out a new copy of the source tree, the existing maven
scripts for autogenerating the website will break, and you can no
longer use it with Eclipse out of the box - you will need to install
Subclipse.

I've already ported over the repositories and I've tested out
committing, Eclipse integration, etc.  I've given SVN commit access to
everyone who had CVS commit access.

For the time being, the repositories are available from both CVS and
Subversion.  But at some point next week, I want to turn off CVS
access and transition entirely to Subversion.

Steps to moving over to Subversion:

 1. If you are using Eclipse, install the Subclipse plugin by going to
"Help -> Software Updates -> Find and Install", then clicking "Search
for new features to install" and "Add new remote site".  Add the site
"http://subclipse.tigris.org/update_1.0.x" and continue, then select
Subclipse to be installed.

 2. If you are using cygwin, run the cygwin setup utility and install
the subversion package.

 3. Run CVS update on your existing checkout to update to the latest
version and find any modifications you want to keep.

 4. Check out a clean copy of the tree using Eclipse.  Click on the
"Open Perspective" button, then on "SVN Repository Exploring".  Right
click and add these repositories:
    https://svn.sourceforge.net/svnroot/bddbddb
    https://svn.sourceforge.net/svnroot/javabdd
    https://svn.sourceforge.net/svnroot/joeq
Browse into the trunk directory of each repository and right-click to
"Checkout..." the projects that you need.  (If you have changes in the
existing project you want to keep, you might want to move the project
directory out of the way first.)
    You can also do it from the command line by using this command:
     svn co https://svn.sourceforge.net/svnroot/joeq/trunk joeq_core
    (Change 'joeq' to 'javabdd' or 'bddbddb' as necessary.)

 5. Move any modified files you want to keep into the newly checked
out tree, and commit them if necessary.

Command-line subversion works much like command-line CVS.  The major
difference is to see what files you have modified, you can type "svn
status" rather than "cvs update -Pd".

If you could send an email when you've successfully made the
transition, that would be great.
