Move a project from an SVN repository to another one

Today, I need to move a project from a first subversion repository to a second one. To do that, you need to have an access to your SVN server.

So, we will use the following commands :
svnadmin dump to backup the repositories (I insist on 'repositories'. I think it's important to have backups of all repos before doing such operations)svndumpfilter to reduce the backup scope to a single project because the dump can only be done on the entire SVN repositorysvnadmin load (I think you can guess what this wonderful command does)To understand this commands, it's important to know that svnadmin uses standard inputs and outputs. Thus, we can combine commands with pipes.


Let's save our project (with all its history, tags, branches...)

svnadmin dump /home/subversion/svn/repo/ | svndumpfilter include myproject > svn.myproject.dump

Now, let's backup our target repository :

svnadmin dump /home/subversion/svn/new_repo/ > svn.new_repo.dump

And let's import the project on th…

Modify your host networking interface with Virtual Box OSE 2.0.4

In the previous post, I talked about how to start a Windows XP image downloaded from Microsoft to be able to test your web application with Internet Explorer.

On Ubuntu 8.04 and Virtual Box OSE (Open Source Edition) 2.0.4, there are some fixes to do before being able to work with the hosted mode network interface.

I took the following instructions from the french Ubuntu forum (http://forum.ubuntu-fr.org/viewtopic.php?id=217680).

1) install bridge-utils and uml-utilities (sudo apt-get)
2) add the vboxusers usergroup to your user :

$ sudo usermod -a -G vboxusers

3) Create a bridge by modifying you /etc/network/interfaces file

For DHCP conf

$ sudo gedit /etc/network/interfaces
auto eth0
iface eth0 inet manual

auto breth0
iface breth0 inet dhcp
bridge_ports eth0

# The loopback network interface
auto lo
iface lo inet loopback

For static IP conf

$ sudo gedit /etc/network/interfaces
auto eth0
iface eth0 inet manual

auto breth0
iface breth0 inet static
bridge_ports eth0
address 192.168.0.2
netmask 255.25…

Internet Explorer free under Ubuntu Linux with VirtualBox

This is a title I found on a blog (http://www.railsgeek.com/). You all know this kind of crisis when delivering a web application developed on your favourite Linux with FireFox : your piece of software crashes on Internet Explorer. You also know how it's difficult to have a IE quickly running on your Ubuntu. Perhaps you tested IE4Linux but it's an old projet. Thanks to Microsoft (yes, I can say this), you have a solution from now.

1) Go to the Microsoft download website : http://www.microsoft.com/downloads
2) Enter 'vpc images' in the search text field
3) You will have an answer titled :

IE App Compat VHD
VPC Hard Disk Images for testing websites with different Internet Explorer versions on Windows XP and Windows Vista

4) Click on the link and download an image (I took IE7-XPSP3.exe)
5) Rename it with the rar extension (ie IE7-XPSP3.rar) and unrar it
6) Install VirtualBox with Synaptic. This excellent software is able to read Microsoft Virtual PC image disk (VHD)
7) The first …
