<h1 class="title">Koji - Packagedb Interaction</h1>
<p>For F7, we're going to have packagers interact with the packagedb.  The packagedb will spawn actions in koji.  For F8, we'll work on integrating the database for the packagedb and the database for koji and a unified front end to access everything.</p>
<div class="section">

<p>These are the tables where koji and the packagedb meet and the differences between them:</p>

-- here we track the built packages

PackageDB:

-- Specific version of a package to be built.

-- :id: Easily referenced primary key
-- :packageId: The package this is a specific build of.

Koji:

CREATE TABLE changelogs (

build_id INTEGER NOT NULL REFERENCES build (id),
date TIMESTAMP NOT NULL,
author TEXT NOT NULL,

The PackageDB logs changes to most tables. Here's the portion that logs changes to the packages:

PackageDB:

-- Log a change to the packageDB.
--
-- Fields:
-- :id: Primary key
-- :userId: Who made the change.
-- :changeTime: Time that the change occurred.
-- :description: Additional information about the change.
create table Log (
id serial primary key,
userId integer not null,
changeTime timestamp default now() not null,
description text
);

-- Log a change made to the Package table.
--
-- Fields:
-- :logId: The id of the log entry.
-- :packageId: The package that changed.
-- :action: What happened to the package.
create table PackageLog (
logId integer primary key,
packageId integer not null,
action integer not null,
foreign key (logId) references Log(id)
on delete cascade on update cascade,
foreign key (packageId) references Package(id)
on delete restrict on update cascade,
foreign key (action) references PackageLogStatusCode (statusCodeId)
on delete restrict on update cascade
);

<a id="tags-collections" name="tags-collections">Tags/Collections</a>

Koji has several tables with information about tags. Need to fill in information about what they do.

The PackageDB has a table for Collections. Then it has Listing tables to associate entities with a collection.

This area needs to be fully looked into.

<a id="notes" name="notes">Notes</a>

These should eventually be better organized.

Koji's primary purpose is to support a buildsystem. It has more information related to that. The PackageDB's primary purpose is to define ownership and permissions related to the Package Sources. The two pieces have some overlap where the sources are handed off to the buildsystem but there doesn't lok to be a whole lot of conflict, rather each piece is concerned with different information about the packages.

We will want to look into replacing Koji's concept of users, groups, and permissions in the long term. The PackageDB ties into the FAS and koji will need to as well. When we do that, we'll need to talk with mikem about how to do it in a generic manner.

Koji has groups that interact with comps -- but I believe it's comps specific to the build system. (ie: not what anaconda sees.) We'll need to look at how that interacts with our plans to use categories for packages and build anaconda comps files from that.
