<title>Concepts and Reference</title>
<para>
In order to configure and use Toaster, you should understand some
concepts and have some basic command reference material available.
This final chapter provides conceptual information on layer sources,
releases, and JSON configuration files.
Also provided is a quick look at some useful
<filename>manage.py</filename> commands that are Toaster-specific.
Information on <filename>manage.py</filename> commands does exist
across the Web and the information in this manual by no means
attempts to provide a command comprehensive reference.
</para>
<section id='layer-source'>
<title>Layer Source</title>
<para>
In general, a "layer source" is a source of information about
existing layers.
In particular, we are concerned with layers that you can use
with the Yocto Project and Toaster.
This chapter describes a particular type of layer source called
a "layer index."
</para>
<para>
A layer index is a web application that contains information
about a set of custom layers.
A good example of an existing layer index is the
OpenEmbedded Metadata Index.
A public instance of this layer index exists at
<ulink url='http://layers.openembedded.org'></ulink>.
You can find the code for this layer index's web application at
<ulink url='http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/'></ulink>.
</para>
<para>
When you tie a layer source into Toaster, it can query the layer
source through a
<ulink url='http://en.wikipedia.org/wiki/Representational_state_transfer'>REST</ulink>
API, store the information about the layers in the Toaster
database, and then show the information to users.
Users are then able to view that information and build layers
from Toaster itself without worrying about cloning or editing
the BitBake layers configuration file
<filename>bblayers.conf</filename>.
</para>
<para>
Tying a layer source into Toaster is convenient when you have
many custom layers that need to be built on a regular basis by
a community of developers.
In fact, Toaster comes pre-configured with the OpenEmbedded
Metadata Index.
<note>
You do not have to use a layer source to use Toaster.
Tying into a layer source is optional.
</note>
</para>
<section id='layer-source-using-with-toaster'>
<title>Setting Up and Using a Layer Source</title>
<para>
To use your own layer source, you need to set up the layer
source and then tie it into Toaster.
This section describes how to tie into a layer index in a manner
similar to the way Toaster ties into the OpenEmbedded Metadata
Index.
</para>
<section id='understanding-your-layers'>
<title>Understanding Your Layers</title>
<para>
The obvious first step for using a layer index is to have
several custom layers that developers build and access using
the Yocto Project on a regular basis.
This set of layers needs to exist and you need to be
familiar with where they reside.
You will need that information when you set up the
code for the web application that "hooks" into your set of
layers.
</para>
<para>
For general information on layers, see the
"<ulink url='&YOCTO_DOCS_BSP_URL;#bsp-layers'>BSP Layers</ulink>"
and
"<ulink url='&YOCTO_DOCS_BSP_URL;#using-the-yocto-projects-bsp-tools'>Using the Yocto Project's BSP Tools</ulink>"
sections in the Yocto Project Board Support Package (BSP)
Developer's Guide.
</para>
</section>
<section id='configuring-toaster-to-hook-into-your-layer-source'>
<title>Configuring Toaster to Hook Into Your Layer Index</title>
<para>
If you want Toaster to use your layer index, you must host
the web application in a server to which Toaster can
connect.
You also need to give Toaster the information about your
layer index.
In other words, you have to configure Toaster to use your
layer index.
This section describes two methods by which you can
configure and use your layer index.
</para>
<para>
In the previous section, the code for the OpenEmbedded
Metadata Index (i.e.
<ulink url='http://layers.openembedded.org'></ulink>) was
referenced.
You can use this code, which is at
<ulink url='http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/'></ulink>,
as a base to create your own layer index.
</para>
<section id='use-the-administration-interface'>
<title>Use the Administration Interface</title>
<para>
Access the administration interface through a
browser by entering the URL of your Toaster instance and
adding "<filename>/admin</filename>" to the end of the
URL.
As an example, if you are running Toaster locally, use
the following URL:
<literallayout class='monospaced'>
http://127.0.0.1:8000/admin
</literallayout>
</para>
<para>
The administration interface has a "Layer sources"
section that includes an "Add layer source" button.
Click that button and provide the required information.
Make sure you select "layerindex" as the layer source type.
</para>
</section>
<section id='select-the-toasterconf-json-file'>
<title>Use the <filename>toasterconf.json</filename> File</title>
<para>
If you do not want to use the Administration
Interface, you can edit the
<link linkend='toaster-json-files'><filename>toasterconf.json</filename></link>
file and reload it to Toaster.
</para>
<para>
When you set up Toaster in Build Mode, you are prompted
to select a Toaster configuration file.
This configuration file is used to set up the initial
configuration values within the Toaster database
including the layer sources.
Three versions of the configuration file exist:
<itemizedlist>
<listitem><para>
The first version of the file is found in the
<filename>conf</filename> directory of the
<filename>meta-yocto</filename> layer
(i.e.
<filename>meta-yocto/conf/toasterconf.json</filename>).
This version contains the default Yocto Project
configuration for Toaster.
You are prompted to select this file during the
Toaster set up process if you had cloned the
<filename>poky</filename> repository (i.e.
<filename>git://git.yoctoproject.org/poky</filename>).
</para></listitem>
<listitem><para>
The second version of the file is in the
<filename>conf</filename> directory of the
<filename>openembedded-core</filename> layer
(i.e. <filename>meta/conf/toasterconf.json</filename>).
This version contains the default OpenEmbedded
configuration for Toaster.
You are prompted to select this file during the
Toaster set up process if you had cloned the
<filename>openembedded-core</filename> repository
(i.e.
<filename>git://git.openembedded.org/openembedded-core</filename>).
</para></listitem>
<listitem><para>
The third version is a sample configuration
useful for when you want to set up a hosted
service in Build Mode.
You can find this version on the
<ulink url='https://wiki.yoctoproject.org/wiki/File:Toasterconf.json.txt.patch'>File:Toasterconf.json.txt.patch</ulink>
wiki page.
</para></listitem>
</itemizedlist>
</para>
</section>
<section id='edit-the-configuration-file'>
<title>Edit the Configuration File</title>
<para>
Edit the version of the
<filename>toasterconf.json</filename> file you
used to set up your Toaster instance.
In the file, you will find a section for layer sources
such as the following:
<literallayout class='monospaced'>
"layersources": [
{
"name": "Local Yocto Project",
"sourcetype": "local",
"apiurl": "../../",
"branches": ["HEAD", "master", "fido", "dizzy"],
"layers": [
{
"name": "openembedded-core",
"local_path": "meta",
"vcs_url": "remote:origin",
"dirpath": "meta"
},
{
"name": "meta-yocto",
"local_path": "meta-yocto",
"vcs_url": "remote:origin",
"dirpath": "meta-yocto"
},
{
"name": "meta-yocto-bsp",
"local_path": "meta-yocto-bsp",
"vcs_url": "remote:origin",
"dirpath": "meta-yocto-bsp"
}
]
},
{
"name": "OpenEmbedded",
"sourcetype": "layerindex",
"apiurl": "http://layers.openembedded.org/layerindex/api/",
"branches": ["master", "fido", "dizzy"]
},
{
"name": "Imported layers",
"sourcetype": "imported",
"apiurl": "",
"branches": ["master", "fido", "dizzy", "HEAD"]
}
],
</literallayout>
You should add your own layer source to this section by
following the same format used for the "OpenEmbedded"
layer source shown above.
</para>
<para>
Give your layer source a name, provide the URL of your
layer source API, use the source type "layerindex", and
indicate which branches from your layer source you want
to make available through Toaster.
For example, the OpenEmbedded layer source makes
available only its "master", "fido", and "dizzy"
branches.
</para>
<para>
The branches must match the branch you
set when configuring your releases.
For example, if you configure one release in Toaster
by setting its branch to "branch-one" and you configure
another release in Toaster by setting its branch to
"branch-two", the branches in your layer source should
be "branch-one" and "branch-two" as well.
Doing so creates a connection between the releases
and the layer information from your layer source.
Thus, when users create a project with a given
release, they will see the appropriate layers from
your layer source.
This connection ensures that only layers that are
compatible with the selected project release can be
selected for building.
</para>
<para>
Once you have added this information to the
<filename>toasterconf.json</filename> file, save your
changes.
</para>
<para>
In a terminal window, navigate to the directory that
contains the Toaster database, which by default is the
root of the Yocto Project
<ulink url='&YOCTO_DOCS_DEV_URL;#source-directory'>Source Directory</ulink>.
Once you are located in that directory, run the
"<filename>loadconf</filename>" command, which takes as
an argument the full path to the
<filename>toasterconf.json</filename> file you just edited.
For example, if you cloned the
<filename>poky</filename> repository and you edited the
<filename>meta-yocto/conf/toasterconf.json</filename> file,
you would type something like the following:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py loadconf /home/scottrif/poky/meta-yocto/conf/toasterconf.json
</literallayout>
After entering this command, you need to update the
Toaster database with the information coming from your
new layer source.
To do that, you should run the
"<filename>lsupdates</filename>" command from the directory
that contains the Toaster database.
Here is an example:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py lsupdates
</literallayout>
If Toaster can reach the API URL, you should see a message
telling you that Toaster is updating the layer source
information.
</para>
<para>
Once the information has been updated, verify the new layer
information is available by using the Toaster web interface.
To do that, visit the "All compatible layers" page inside a
Toaster project.
The layers from your layer source should be listed there.
</para>
</section>
</section>
</section>
</section>
<section id='toaster-releases'>
<title>Releases</title>
<para>
When you create a Toaster project using the web interface,
you are asked to choose a "Release."
In the context of Toaster, the term "Release" refers to a set of
layers and a BitBake version the OpenEmbedded build system uses
to build something.
As shipped, Toaster is pre-configured with releases that
correspond to Yocto Project release branches.
However, you can modify, delete, and create new releases
according to your needs.
This section provides some background information on releases.
</para>
<section id='toaster-releases-supported'>
<title>Pre-Configured Releases</title>
<para>
As shipped, Toaster is configured to use a specific set of
releases.
Of course, you can always configure Toaster to use any
release.
For example, you might want your project to build against a
specific commit of any of the "out-of-the-box" releases.
Or, you might want your project to build against different
revisions of OpenEmbedded and BitBake.
</para>
<para>
As shipped, Toaster is configured to work with the following
releases:
<itemizedlist>
<listitem><para><emphasis>Yocto Project 1.7 "Dizzy" or OpenEmbedded "Dizzy":</emphasis>

<section id='toaster-releases-comprised-of'>
<title>What Makes Up a Release?</title>
<para>
A release consists of the following:
<itemizedlist>
<listitem><para><emphasis>Name:</emphasis>
The name of the release (<filename>name</filename>).
This release name never appears in the the Toaster
web interface.
Consequently, a user never sees the release name.
</para></listitem>
<listitem><para><emphasis>Description:</emphasis>
The textual description of the release
(<filename>description</filename>).
This description is what users encounter when creating
projects with the Toaster web interface.
When you configure your release, be sure to use
a description that sufficiently describes and is
understandable.
If Toaster has more than one release configured, the
release descriptions appear listed in a drop down menu
when a user creates a new project.
If Toaster has only one release configured, all
projects created using the web interface take that
release and the drop down menu does not display in the
Toaster web interface.
</para></listitem>
<listitem><para><emphasis>BitBake:</emphasis>
The Bitbake version (<filename>bitbake</filename>)
used to build layers set in the current release.
This version is described by a name, a Git URL, a
branch in the Git URL, and a directory path in the
Git repository.
As an example, consider the following snippet from
a Toaster JSON configuration file.
This BitBake version uses the master branch from the
OpenEmbedded repository:
<literallayout class='monospaced'>
"bitbake" : [
{
"name": "master",
"giturl": "git://git.openembedded.org/bitbake",
"branch": "master",

Here is more detail on each of the items that comprise
the BitBake version:
<itemizedlist>
<listitem><para><emphasis>Name:</emphasis>
A string
(<filename>name</filename>) used to refer to
the version of BitBake you are using with
Toaster.
This name is never exposed through Toaster.
</para></listitem>
<listitem><para><emphasis>Git URL:</emphasis>
The URL (<filename>giturl</filename>)
for the BitBake Git repository cloned
for Toaster projects.
</para></listitem>

The Git branch, or revision,
(<filename>branch</filename>) of the BitBake
repository used with Toaster.
</para></listitem>
<listitem><para><emphasis>Directory Path:</emphasis>
The sub-directory of the BitBake repository
(<filename>dirpath</filename>).
If the Git URL includes more than one
repository, you need to set this directory.
If the URL does not include more than a single
repository, you can set
<filename>dirpath</filename> to a null string
(i.e. "").
</para></listitem>
</itemizedlist>
</para></listitem>
<listitem><para><emphasis>Branch:</emphasis>
The branch for the layer source

<listitem><para><emphasis>Layer Source Priorities</emphasis>
A specification of
<link linkend='layer-source'>layer source</link>
priorities (<filename>layersourcepriority</filename>).
In order for Toaster to work as intended, the
"Imported layers" layer source should have the highest
priority, which means that layers manually imported by
users with the "Import layer" functionality will
always be visible and available for selection.
</para></listitem>
<listitem><para><emphasis>Help Text:</emphasis>
Help text (<filename>helptext</filename>) that explains
what the release does when selected.
This help text appears below the release drop-down

project.
</para></listitem>
</itemizedlist>
</para>
<para>
To summarize what comprises a release, consider the following
example from a Toaster JSON file.
The configuration names the release "master" and uses the
"master" branch provided by the layer source of type
"layerindex", which is called "OpenEmbedded", and sets
the <filename>openembedded-core</filename> layer as the one
to be added by default to any projects created in Toaster.
The BitBake version used would be defined as shown earlier
in the previous list:
<literallayout class='monospaced'>
"releases": [
{
"name": "master",
"description": "OpenEmbedded master",
"bitbake": "master",
"branch": "master",
"defaultlayers": [ "openembedded-core" ],
"layersourcepriority": { "Imported layers": 99, "Local OpenEmbedded" : 10, "OpenEmbedded" : 0 },
"helptext": "Toaster will run your builds using the OpenEmbedded master branch, where active development takes place. This is not a stable branch, so your builds might not work as expected."
}
]

</para>
</section>
</section>
<section id='toaster-json-files'>
<title>JSON Files</title>
<para>
If you are going to be using Toaster in Build Mode, it must
be initially configured before use.
Configuration customizes layer source settings and Toaster defaults
for all users and is performed by the person responsible for
Toaster Configuration (i.e the Toaster Administrator).
The Toaster Administrator performs this configuration through the
Django administration interface.
</para>
<para>
To make it easier to initially start Toaster, you can import a
pre-defined configuration file using the
<link linkend='toaster-command-loadconf'><filename>loadconf</filename></link>
command.
<note>
The configuration file is a JSON-formatted text file with
specific fields that Toaster recognizes.
It is not a data dump from the database, so it cannot be
loaded directly in the database.
</note>
</para>
<para>
By convention, the supplied configuration files are named
<filename>toasterconf.json</filename>.
The Toaster Administrator can customize the file prior to loading
it into Toaster.
When you set up Toaster locally to run in Build Mode, the system
startup script actively looks for compatible configuration files
and prompts you to select a file to load if it detects that the
database has not been configured.

<title>Useful Commands</title>
<para>
In addition to the web user interface and the scripts that start
and stop Toaster, command-line commands exist through the
<filename>manage.py</filename> management script.
You can find general documentation on
<filename>manage.py</filename> at the
<ulink url='https://docs.djangoproject.com/en/1.7/topics/settings/'>Django</ulink>
site.
However, several <filename>manage.py</filename> commands have been
created that are specific to Toaster and are used to control
configuration and back-end tasks.
You can locate these commands in the
<ulink url='&YOCTO_DOCS_DEV_URL;#source-directory'>Source Directory</ulink>
(e.g. <filename>poky</filename>) at
<filename>bitbake/lib/manage.py</filename>.
This section documents those commands.
<note>
<para>
When using <filename>manage.py</filename> commands given
a default configuration, you must be sure that your
working directory is set to the
<ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink>.
Using <filename>manage.py</filename> commands from the
Build Directory allows Toaster to find the
<filename>toaster.sqlite</filename> file, which is located
in the Build Directory.
</para>
<para>
For non-default database configurations, it is possible
that you can use <filename>manage.py</filename> commands
from a directory other than the Build directory.
To do so, the
<filename>toastermain/settings.py</filename> file must be
configured to point to the correct database backend.
</para>
</note>
</para>
<section id='toaster-command-buildslist'>
<title><filename>buildslist</filename></title>
<para>
The <filename>buildslist</filename> command lists all builds
that Toaster has recorded.
Access the command as follows:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py buildslist
</literallayout>
The command returns a list, which includes numeric
identifications, of the builds that Toaster has recorded in the
current database.
</para>
<para>
You need to run the <filename>buildslist</filename> command
first to identify existing builds in the database before
using the
<link linkend='toaster-command-builddelete'><filename>builddelete</filename></link>
command.
Here is an example that assumes default repository and build
directory names:
<literallayout class='monospaced'>
$ cd ~/poky/build
$ python ../bitbake/lib/toaster/manage.py buildslist
</literallayout>
If your Toaster database had only one build, the above
<filename>buildslist</filename> command would return something
like the following:
<literallayout class='monospaced'>
1: qemux86 poky core-image-minimal
</literallayout>
</para>
</section>
<section id='toaster-command-builddelete'>
<title><filename>builddelete</filename></title>
<para>
The <filename>builddelete</filename> command deletes data
associated with a build.
Access the command as follows:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py builddelete <replaceable>build_id</replaceable>
</literallayout>
The command deletes all the build data for the specified
<replaceable>build_id</replaceable>.
This command is useful for removing old and unused data from
the database.
</para>
<para>
Prior to running the <filename>builddelete</filename>
command, you need to get the ID associated with builds
by using the
<link linkend='toaster-command-buildslist'><filename>buildslist</filename></link>
command.
</para>
</section>
<section id='toaster-command-perf'>
<title><filename>perf</filename></title>
<para>
The <filename>perf</filename> command measures Toaster
performance.
Access the command as follows:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py perf
</literallayout>
The command is a sanity check that returns page loading
times in order to identify performance problems.
</para>
</section>
<section id='toaster-command-checksettings'>
<title><filename>checksettings</filename></title>
<para>
The <filename>checksettings</filename> command verifies
existing Toaster settings.
Access the command as follows:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py checksettings
</literallayout>
In Build Mode, Toaster uses settings that are based on the
database to configure the building tasks.
The <filename>checksettings</filename> command verifies that
the database settings are valid in the sense that they have
the minimal information needed to start a build.
</para>
<para>
In order for the <filename>checksettings</filename> command
to work, the database must be correctly set up and not have
existing data.
To be sure the database is ready, you can run the following:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/mana​ge.py syncdb
$ bitbake/lib/toaster/mana​ge.py migrate orm
$ bitbake/lib/toaster/mana​ge.py migrate bldcontrol
</literallayout>
After running these commands, you can run the
<filename>checksettings</filename> command.
</para>
</section>
<section id='toaster-command-loadconf'>
<title><filename>loadconf</filename></title>
<para>
The <filename>loadconf</filename> command loads an
existing Toaster configuration file (JSON file).
You must run this on a new database that does not have any
data.
Running this command on an existing database that has data
results in errors.
Access the command as follows:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py loadconf <replaceable>filepath</replaceable>
</literallayout>
The <filename>loadconf</filename> command configures a database
based on the supplied existing
<filename>toasterconf.json</filename> file.
For information on the <filename>toasterconf.json</filename>,
see the
"<link linkend='toaster-json-files'>JSON Files</link>"
section.
</para>
</section>
<section id='toaster-command-runbuilds'>
<title><filename>runbuilds</filename></title>
<para>
The <filename>runbuilds</filename> command launches
scheduled builds.
Access the command as follows:
<literallayout class='monospaced'>
$ bitbake/lib/toaster/manage.py runbuilds
</literallayout>
The <filename>runbuilds</filename> command checks if
scheduled builds exist in the database and then launches them
per schedule.
The command returns after the builds start but before they
complete.
The Toaster Logging Interface records and updates the database
when the builds complete.
