Difference between revisions of "Adding Information To pluto media"

Revision as of 13:01, 9 September 2009

pluto_media contains a mix of media information relevant for the local install, and configuration information relevant for the building of packages. pluto_media updates to the configuration, like the MediaSource table, needs to be re-done on the main mysql server (currently located at schema.linuxmce.org).

After amending the MySQL database pluto_media on schema.linuxmce.org, sqlCVS needs to be run on schema and the psc IDs need to be updated by selecting update-psc

sqlCVS -D pluto_media update-psc

Example of adding a record to pluto_media.MediaSource

Adding the record on the main MySQL server (schema.linuxmce.org as of this writing)

We need to add a new type of MediaSource to the system. This is, how it was done:

[root@lmce-svn ~]# mysql pluto_media
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 68301
Server version: 5.0.45 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> select * from MediaSource;

Update SVN to know about this new media source

On our builder, we do an import of the database

/usr/local/lmce-build/build-scripts/import-databases.sh

Now we have the updated databases on the builder. Let's verify

root@Ubuntu-904-jaunty-64-minimal:/usr/local/lmce-build#  mysql pluto_media -e "select * from MediaSource;"

That looks good. Now, we need to update the codebase to reflect the new MediaSource. We use sql2cpp for this.

LD_LIBRARY_PATH=/var/lmce-build/MakeRelease /var/lmce-build/svn/branches/LinuxMCE-0810/src/sql2cpp/sql2cpp -i \
/var/lmce-build/svn/branches/LinuxMCE-0810/src/sql2cpp/ -o /var/lmce-build/svn/branches/LinuxMCE-0810/src/pluto_media \
-D pluto_media -h localhost
