Subversion (SVN) 1.4 on Ubuntu Edgy Howto
I recently updated my the version of SubClipse to a version which used svn 1.4 - which has some incompatible improvements to the working copy format.
WARNING: if a Subversion 1.4 client encounters a pre-1.4 working copy, it will automatically upgrade the working copy format as soon as it touches it, making it unreadable by older Subversion clients. If you are using several versions of Subversion on your machine, you need to be careful about which version you use in which working copy, to avoid accidentally upgrading the working copy format. This "auto upgrade" feature, however, does not occur with the new repository format.
Here is a small howto on installing SVN 1.4 on Ubuntu as there are no packages for Edgy yet (if ever).
Download the following two files:
http://subversion.tigris.org/downloads/subversion-1.4.2.tar.bz2
http://subversion.tigris.org/downloads/subversion-deps-1.4.2.tar.bz2
Wait a bit... http://subversion.tigris.org/downloads/subversion-deps-1.4.2.tar.bz2
Extract the files on your machine and configure:
tar xjvf subversion-1.4.2.tar.bz2
tar xjvf subversion-deps-1.4.2.tar.bz2
cd subversion-1.4.2
./configure --enable-ssl
Wait a bit more... tar xjvf subversion-deps-1.4.2.tar.bz2
cd subversion-1.4.2
./configure --enable-ssl
Compile the application:
make
Go and get lunch - or write a blog entry. Install the application:
sudo make install
Subversion should now be installed in /usr/local/bin and you can verify that it will be used on the path by doing the following:
svn --version --quiet
1.4.2
1.4.2
If you get an earlier version then you may need to close and reopen your terminal to update the path info.
Optional javahl config - untested
If you are using subclipse you may also want to install the javahl bindings the process would be:./configure --enable-ssl --enable-javahl --with-jdk=$JAVA_HOME --with-jikes=$JAVA_HOME/bin/javac
make
make javahl
make install
make install-javahl
Note: you will need a java jdk installed instead of just a jre eg: sudo apt-get install sun-java5-jdk make
make javahl
make install
make install-javahl

Also, in the steps you performed, you will not have SSL support because you did not pass --enable-ssl to configure. I could be wrong, maybe configure is smart enough to detect it itself. If you run svn version without the --quiet switch you would see the ra methods you have built. I am guessing you will not see https included in the list.
Is my understanding correct: with JavaHL subclipse will use the installed version of svn instead of relying on it's on pure java version. This would certainly avoid this problem.
Is that the only reason for your preference or are there other reasons too?
You are right about the enable ssl switch - I'll update the instructions.
Speaking generally, there are no advantages to one interface versus the other, but there are specific scenarios where one can be a better option. For example, SVNKit uses Java for all of its http communication. By default, Java cannot support the SSL of most sites because of encryption export standards. You can update the JCE to a higher strength, but even then I have found it cannot handle the certs from some sites. That is just an example, there are cases where SVNKit has better options too.
Personally, I just prefer to be using the same Subversion code that the command line uses as you know that multiple clients will then all behave the same.
What are "the necessary steps so that it can be found via a JNI call" - can you point me to some instructions on this?
Also - I tried to build it will --enable-ssl and it doesn't work - I presume I need the openssl source or similar but can't find any documentation on this - any pointers?
Thanks for you feedback.
Cheers,
Mark

As for SSL, yes you need OpenSSL installed (odd that it wouldn't be) and normally configure should just detect it and setup the necessary linkage.
