Subversion repository part migration

svnadmin dump /srv/svn/old-repo | svndumpfilter include --drop-empty-revs --renumber-revs /directory-name > directory.svndump
svnadmin load /srv/svn/new-repo < directory.svndump

Please note, that if directory structure needs to be changed (for example, from /old-repo/projects/dir to /new-repo/dir) manual edit of dump file will not help. Instead, sed must be combined with svndumpfilter. Additional info regarding this topic can be found here.

Virtualbox 3.1.x Linux guest dead keyboard fix

After new release of Virtualbox was installed and my virtual machine with OpenSUSE on-board had started, I've ended up with a dead keyboard. It worked fine on Windows XP as host, but OpenSUSE VM was acting like there is no keyboard at all. Couple of minutes of brain activity and finger work I've found that /etc/X11/xorg.conf was replaced during Virtualbox Guest Additions update. Comparing xorg.conf between two latest VB releases, I was able to get the keyboard working. Here is a fix:

1. Restore old xorg.conf :

cp /etc/X11/xorg.conf.bak /etc/X11/xorg.conf

2. Add Option "CoreKeyboard" to InputDevice section of Keyboard[0]
3. Add Option "CorePointer" to InputDevice section of Mouse[1]
4. Add Option "SendCoreEvents" to InputDevice section of Mouse[2]
5. Rename Device option from InputDevice section of Mouse[2] from /dev/vboxadd to /dev/vboxguest

How to remove absolute path in svn+ssh

As you may or may not know there is a path difference between svn and svn+ssh links in case if subversion server is configured with default root directory:

/etc/sysconfig/svnserve

SVNSERVE_OPTIONS="-d -R -r /path-to-repos"

This way repository can be checked out using following commands (consider ssh is set up and working):

svn co svn://server.com/repository directory

or

svn co svn+ssh://server.com/path-to-repos/repository directory
