== Sprint Goals ==

 1. Migrate old SVN projects to new SVN instance
 2. Develop framework to organize existing code
 3. How to use wiki to reference/shortcut/organize/manage SVN


== Sprint Tasks ==
...to meet above goals
 * Overview of wiki formatting
 * Overview/best practices of SVN
 * List available code
 * Decide on components and projects to organize above code
 * start placing code in SVN
 * Start wiki pages to point to code of interest


== Available Projects ==

[http://trac.nccoos.org Top Level project tree]

Projects give control over areas of work and responsible people. Each project has a number of components which are deployable source trees within a given project.  The following outline is a brain dump of current code pieces that are maintained and stored by Sara, Jesse, and Chris to see how they fit into the framework of Projects. The "production" processes live and run on various computers. 

Some possible projects are:

 * Platforms
   * Sara 
     * data_acquisition (eVB)
     * daqLib (eVC)
     * data_transfer (eVB)
     * commLib (eVC)

 * Telemetry
 * Repository 
 * [http://trac.nccoos.org/datamgmt Data Management] '''change this project name to Data Processing'''
   * Jesse
     * GDP drifters (via AOML) to Xenia DB (seacoos)
     * CODAR to shapefile (seacoos)
     * QuikSCAT (seacoos)
   * Sara (buoy, tower) (met, ctd, adcp)
     * populate level0 (realtime and manual) (push and get) 
     * raw2proc (level0 to level1) 
     * proc2ndbc (push fm13 and fm64 to NDBC)
     * proc2latest (provide SEACOOS netCDF of latest data)
     * generate html tables (realtime)
   * Sara (codar) (surface currents)
     * tar2ms.pl (tar monthly CODAR raw spectra and rangefiles and and scp to mass-storage)
     * combine radial sites to total surface currents
     * radials proc2latest (provide SEACOOS netCDF of latest data)
     * totals proc2latest (provide SEACOOS netCDF of latest data)

 * Database
   * nccoos_obs DB
   
 * Visualization
   * Jesse
     * Chameleon application
     * NCCOOS interactive map application
     * Base mapfiles
     * OGC CGI wrappers
     * OGC mapfiles - parallel to SC feeds
     * Sandbox WMS applications
   * Sara 
     * proc2tsplot (last 24 hours, last 7 days, last 30 days timeseries plots)
     * lastest2map (latest obs and various model maps)

= SVN and Trac Demonstration =

A demostration of how to implement our framework of Projects and code components in SVN and Trac.  We will be creating the Platforms repository and project and component daqLib under the Platforms.

Keep in mind that a Trac Project corresponds to an SVN Repository and a Trac Component corresponds to an SVN folder in Repository

== Create Subversion Repository and Folder ==

login as root to coriolis.marine.unc.edu 
% ssh root@coriolios.marine.unc.edu
passwd:

% cd /var/srv
% ls
svn trac

instances of svn on coriolis
% ls svn
nccoos seacoos

% which svnadmin
/usr/bin/svnadmin

list help commands and help on specific command usage
% svnadmin help
% svnadmin help create

% svnadmin --fs-type fsfs 

list repositories of nccoos
% ls svn/nccoos
datamgmt portal scratch

Create the SVN repository
% svnadmin create --fs-type fsfs /var/srv/svn/nccoos/platforms
NOTE: specify fsfs because doc lies.  It is not default

% ls svn/nccoos
datamgmt platforms portal scratch
% ls snv/nccoos/platforms
conf dav db format hooks locks README.txt

Change permissions on SVN repository
% cd /var/srv/svn/nccoos
% chmod -R apache:root platforms


== Create Trac Project and Compenent ==

Just type to see possible commands that you can use to administer project
% trac-admin 

Interactive 
% trac-admin /var/srv/trac/nccoos/platforms initenv

Project Name [My Project]: NCCOOS Observing Platforms
Database connection string [sqlite:db/trac.db]> use default
Path to repository [/srv/svn]> /var/srv/svn/nccoos/platforms
Templates directory [/usr/share/trac/templates]> use default
more stuff
Congratulations!

more stuff created for trac like svn
% ls trac/nccoos
datamgmt platforms portal scratch

More work to configure Trac
% cd /var/srv/trac/nccoos/platforms/conf
% ls
trac.ini
% vi trac.ini

remove all the default stuff
insert the following stuff for an already good configuration from seacoos
insert ../../portal/conf/trac.ini
edit/change all "portal" stuff that was copied to apply for "platforms"
(need an example or template here) 

Copy existing htdocs from portals for logo and facoicon.ico
% cd ../htdocs
% cp -a ../../portal/htdocs/* .

Change permissions on Trac project
% cd /var/srv/trac/nccoos
% chmod -R apache:root platforms

What to modify for Apache
% cd /etc/httpd/conf.d
% ls
should see "nccoos.conf" in listing

% vi nccoos.conf
duplicate <Location /portal> and change 3 occurences of "portals" to "platforms"

Let Apache know that you changed the configuration
% service httpd restart
Stopping httpd
Starting httpd ...

Add/Set permissions dot-access of SVN 
% cd /var/srv/svn/nccoos
% ls -a
. .. .access datamgmt platforms portal scratch
% vi .access
insert under [groups] who will work on this code
add line "platform-developers = haines"
insert under [scratch:/]
add line "@platforms-develops = rw"

Allow all developers to create new components 
[portal:/] as [platforms:/]
@platforms-developers = rw
cbc = rw
* = r

If want to refine who works on a specific component be specific in .access for example
[platforms:/daqLib]
cbc = rw
haines = rw
* = r
