SVN on Windows

SVN Server

Download windows installer

Choose an installation path without white space in it to make things easier (or remember to escape spaces in the path)

Go for svnserve for an easy setup

Run install with the above choices

Open firewall poer 3690

Verify that the user the service is running as has write access to the repository folder

Create repository (command line)

Edit ./conf/svnserve.conf and ./conf/passwd

Tortoise SVN Client

Download tortoise svn client (explorer shell extension)

Install

Exclude folders not used for workspaces (ie Exclude paths: , Include paths: C:\svnwc\)

Tweaks

Started with a repository under N:\Development\SVN_Rep and in that the folder structure like pbweb/trunk/.... I.e. the repository was supposed to store several projects.

Since trac wants to match it’s projects with a specific svn repository I changed the repository layout to only one project in each repository. So now the repository is in N:\Development\SVN_Rep\projectname. And the folder structure starts with trunk/....

The server serves all repositories under N:\Development\SVN_Rep.

Some CentOS basics

First try
Some basic app admin

chkconfig, activate/deactivate services,

service, start and stop services

system-config-securitylevel

Get VNC up and running

Follow the instructions.

If you get an error that says bad display name when starting the vgcnserver at the end make sure that the machine recognizes it’s name. If not add it to /etc/hosts.

Open up the firewall for 5901 (and perhaps more) by running system-config-securitylevel

Apache

service httpd start

chkconfig httpd on

Works to connect from my windows machine after this

PostgreSQL

Followed the instructions approximately.

Got an error at the Starting postgresql service: prompt.

Read something about SELinux causing problems so I shut it down and rebooted and the server seems to be running. Don’t know if it was related with SELinux though.

Second try

During installation
For tasks, choose “Desktop – Gnome” and Server
Disable firewall and SELinux

Installed software
Perl 5.8.8
mod_perl 2.0.4
httpd 2.2.3
PostgreSQL not installed
Check installed version:

# rpm -q

VNC
As above.

PostgreSQL
8.3.6 install
# rpm -Uvh http://yum.pgsqlrpms.org/reporpms/8.3/pgdg-centos-8.3-6.noarch.rpm
# yum install postgresql-server
Followed the book then a bit for initdb:

# su - postgres
-bash-3.2$ initdb
...
-bash-3.2$ exit
Start service and autostart at reboot:

# service postgresql start
# chkconfig postgresql on

Ended up with 8.3.9 but that should be ok.

Createuser and db:

# su - postgres
-bash-3.2$ createuser XYZ
-bash-3.2$ createdb -O XYZ XYZ

ftp
service vsftpd start
chkconfig vsftpd on

Add data to db
# psql -U XYZ < XYZ.sql

Apache
As above.

Perl stuff

Started with:

# yum install postgresql-devel.x86_64
# yum install gcc
since pg_config and gcc is needed when running:

# cpan install Bundle::DBD::Pg
When checking things out with get_datasources.pl (from the book) make sure to use a user that can read db and script. I added XYZ as a unix user and copied the script to ~ before getting it to work. Don’t know why though.

# cpan install Catalyst::Devel
Results in a million dependencies, just said yes to everything. Something was installed.

Seadragon AJAX

There are plenty of times when you want to see something closer, to get a good look at the texture of a sculpture, or find out if that's a reflection or a scratch on that used car you're looking at.

Seadragon, implemented as the Deep Zoom feature of Silverlight, allows you to do that. But what if you're not using the Silverlight platform? That's what Seadragon Ajax is for.

PS
Seadragon Mobile is available for the iPhone as well!
