-****************************
-Setting Up and Using Toaster
-****************************
-
-Starting Toaster for Local Development
-======================================
-
-Once you have set up the Yocto Project and installed the Toaster system
-dependencies as described in the ":ref:`toaster-manual/toaster-manual-start:Preparing to Use
-Toaster`" chapter, you are ready to start
-Toaster.
-
-Navigate to the root of your
-:term:`Source Directory` (e.g. ``poky``)::
-
- $ cd poky
-
-Once in that directory, source the build environment script::
-
- $ source oe-init-build-env
-
-Next, from the build directory (e.g.
-``poky/build``), start Toaster using this command::
-
- $ source toaster start
-
-You can now run your builds from the command line, or with Toaster
-as explained in section
-":ref:`toaster-manual/toaster-manual-setup-and-use:using the toaster web interface`".
-
-To access the Toaster web interface, open your favorite browser and
-enter the following::
-
- http://127.0.0.1:8000
-
-Setting a Different Port
-========================
-
-By default, Toaster starts on port 8000. You can use the ``WEBPORT``
-parameter to set a different port. For example, the following command
-sets the port to "8400"::
-
- $ source toaster start webport=8400
-
-Setting Up Toaster Without a Web Server
-=======================================
-
-You can start a Toaster environment without starting its web server.
-This is useful for the following:
-
-- Capturing a command-line build's statistics into the Toaster database
- for examination later.
-
-- Capturing a command-line build's statistics when the Toaster server
- is already running.
-
-- Having one instance of the Toaster web server track and capture
- multiple command-line builds, where each build is started in its own
- "noweb" Toaster environment.
-
-The following commands show how to start a Toaster environment without
-starting its web server, perform BitBake operations, and then shut down
-the Toaster environment. Once the build is complete, you can close the
-Toaster environment. Before closing the environment, however, you should
-allow a few minutes to ensure the complete transfer of its BitBake build
-statistics to the Toaster database. If you have a separate Toaster web
-server instance running, you can watch this command-line build's
-progress and examine the results as soon as they are posted::
-
- $ source toaster start noweb
- $ bitbake target
- $ source toaster stop
-
-Setting Up Toaster Without a Build Server
-=========================================
-
-You can start a Toaster environment with the "New Projects" feature
-disabled. Doing so is useful for the following:
-
-- Sharing your build results over the web server while blocking others
- from starting builds on your host.
-
-- Allowing only local command-line builds to be captured into the
- Toaster database.
-
-Use the following command to set up Toaster without a build server::
-
- $ source toaster start nobuild webport=port
-
-Setting up External Access
-==========================
-
-By default, Toaster binds to the loop back address (i.e. ``localhost``),
-which does not allow access from external hosts. To allow external
-access, use the ``WEBPORT`` parameter to open an address that connects
-to the network, specifically the IP address that your NIC uses to
-connect to the network. You can also bind to all IP addresses the
-computer supports by using the shortcut "0.0.0.0:port".
-
-The following example binds to all IP addresses on the host::
-
- $ source toaster start webport=0.0.0.0:8400
-
-This example binds to a specific IP address on the host's NIC::
-
- $ source toaster start webport=192.168.1.1:8400
-
-The Directory for Cloning Layers
-================================
-
-Toaster creates a ``_toaster_clones`` directory inside your Source
-Directory (i.e. ``poky``) to clone any layers needed for your builds.
-
-Alternatively, if you would like all of your Toaster related files and
-directories to be in a particular location other than the default, you
-can set the ``TOASTER_DIR`` environment variable, which takes precedence
-over your current working directory. Setting this environment variable
-causes Toaster to create and use ``$TOASTER_DIR./_toaster_clones``.
-
-The Build Directory
-===================
-
-Toaster creates a build directory within your Source Directory (e.g.
-``poky``) to execute the builds.
-
-Alternatively, if you would like all of your Toaster related files and
-directories to be in a particular location, you can set the
-``TOASTER_DIR`` environment variable, which takes precedence over your
-current working directory. Setting this environment variable causes
-Toaster to use ``$TOASTER_DIR/build`` as the build directory.
-
-Creating a Django Superuser
-===========================
-
-Toaster is built on the `Django
-framework <https://www.djangoproject.com/>`__. Django provides an
-administration interface you can use to edit Toaster configuration
-parameters.
-
-To access the Django administration interface, you must create a
-superuser by following these steps:
-
-#. If you used ``pip3``, which is recommended, to set up the Toaster
- system dependencies, you need be sure the local user path is in your
- ``PATH`` list. To append the pip3 local user path, use the following
- command::
-
- $ export PATH=$PATH:$HOME/.local/bin
-
-#. From the directory containing the Toaster database, which by default
- is the :term:`Build Directory`,
- invoke the ``createsuperuser`` command from ``manage.py``::
-
- $ cd ~/poky/build
- $ ../bitbake/lib/toaster/manage.py createsuperuser
-
-#. Django prompts you for the username, which you need to provide.
-
-#. Django prompts you for an email address, which is optional.
-
-#. Django prompts you for a password, which you must provide.
-
-#. Django prompts you to re-enter your password for verification.
-
-After completing these steps, the following confirmation message
-appears::
-
- Superuser created successfully.
-
-Creating a superuser allows you to access the Django administration
-interface through a browser. The URL for this interface is the same as
-the URL used for the Toaster instance with "/admin" on the end. For
-example, if you are running Toaster locally, use the following URL::
-
- http://127.0.0.1:8000/admin
-
-You can use the Django administration interface to set Toaster configuration
-parameters such as the build directory, layer sources, default variable
-values, and BitBake versions.
-
-Setting Up a Production Instance of Toaster
-===========================================
-
-You can use a production instance of Toaster to share the Toaster
-instance with remote users, multiple users, or both. The production
-instance is also the setup that can handle heavier loads on the web
-service. Use the instructions in the following sections to set up
-Toaster to run builds through the Toaster web interface.
-
-Requirements
-------------
-
-Be sure you meet the following requirements:
-
-.. note::
-
- You must comply with all Apache, ``mod-wsgi``, and Mysql requirements.
-
-- Have all the build requirements as described in the ":ref:`toaster-manual/toaster-manual-start:Preparing to
- Use Toaster`" chapter.
-
-- Have an Apache webserver.
-
-- Have ``mod-wsgi`` for the Apache webserver.
-
-- Use the Mysql database server.
-
-- If you are using Ubuntu, run the following::
-
- $ sudo apt-get install apache2 libapache2-mod-wsgi-py3 mysql-server python3-pip libmysqlclient-dev
-
-- If you are using Fedora or a RedHat distribution, run the
- following::
-
- $ sudo dnf install httpd python3-mod_wsgi python3-pip mariadb-server mariadb-devel python3-devel
-
-- If you are using openSUSE, run the following::
-
- $ sudo zypper install apache2 apache2-mod_wsgi-python3 python3-pip mariadb mariadb-client python3-devel
-
-Installation
-------------
-
-Perform the following steps to install Toaster:
-
-#. Create toaster user and set its home directory to
- ``/var/www/toaster``::
-
- $ sudo /usr/sbin/useradd toaster -md /var/www/toaster -s /bin/false
- $ sudo su - toaster -s /bin/bash
-
-#. Checkout a copy of ``poky`` into the web server directory. You will
- be using ``/var/www/toaster``::
-
- $ git clone git://git.yoctoproject.org/poky
- $ git checkout &DISTRO_NAME_NO_CAP;
-
-#. Install Toaster dependencies using the --user flag which keeps the
- Python packages isolated from your system-provided packages::
-
- $ cd /var/www/toaster/
- $ pip3 install --user -r ./poky/bitbake/toaster-requirements.txt
- $ pip3 install --user mysqlclient
-
- .. note::
-
- Isolating these packages is not required but is recommended.
- Alternatively, you can use your operating system's package
- manager to install the packages.
-
-#. Configure Toaster by editing
- ``/var/www/toaster/poky/bitbake/lib/toaster/toastermain/settings.py``
- as follows:
-
- - Edit the
- `DATABASES <https://docs.djangoproject.com/en/2.2/ref/settings/#databases>`__
- settings:
-
- .. code-block:: python
-
- DATABASES = {
- 'default': {
- 'ENGINE': 'django.db.backends.mysql',
- 'NAME': 'toaster_data',
- 'USER': 'toaster',
- 'PASSWORD': 'yourpasswordhere',
- 'HOST': 'localhost',
- 'PORT': '3306',
- }
- }
-
- - Edit the
- `SECRET_KEY <https://docs.djangoproject.com/en/2.2/ref/settings/#std:setting-SECRET_KEY>`__:
-
- .. code-block:: python
-
- SECRET_KEY = 'your_secret_key'
-
- - Edit the
- `STATIC_ROOT <https://docs.djangoproject.com/en/2.2/ref/settings/#std:setting-STATIC_ROOT>`__:
-
- .. code-block:: python
-
- STATIC_ROOT = '/var/www/toaster/static_files/'
-
-#. Add the database and user to the ``mysql`` server defined earlier::
-
- $ mysql -u root -p
- mysql> CREATE DATABASE toaster_data;
- mysql> CREATE USER 'toaster'@'localhost' identified by 'yourpasswordhere';
- mysql> GRANT all on toaster_data.\* to 'toaster'@'localhost';
- mysql> quit
-
-#. Get Toaster to create the database schema, default data, and gather
- the statically-served files::
-
- $ cd /var/www/toaster/poky/
- $ ./bitbake/lib/toaster/manage.py migrate
- $ TOASTER_DIR=`pwd\` TEMPLATECONF='poky' \
- ./bitbake/lib/toaster/manage.py checksettings
- $ ./bitbake/lib/toaster/manage.py collectstatic
-
-
- In the previous
- example, from the ``poky`` directory, the ``migrate`` command
- ensures the database schema changes have propagated correctly (i.e.
- migrations). The next line sets the Toaster root directory
- ``TOASTER_DIR`` and the location of the Toaster configuration file
- ``TOASTER_CONF``, which is relative to ``TOASTER_DIR``. The
- ``TEMPLATECONF`` value reflects the contents of
- ``poky/.templateconf``, and by default, should include the string
- "poky". For more information on the Toaster configuration file, see
- the ":ref:`toaster-manual/toaster-manual-reference:Configuring Toaster`" section.
-
- This line also runs the ``checksettings`` command, which configures
- the location of the Toaster :term:`Build Directory`.
- The Toaster
- root directory ``TOASTER_DIR`` determines where the Toaster build
- directory is created on the file system. In the example above,
- ``TOASTER_DIR`` is set as follows::
-
- /var/www/toaster/poky
-
-
- This setting causes the Toaster build directory to be::
-
- /var/www/toaster/poky/build
-
- Finally, the ``collectstatic`` command is a Django framework command
- that collects all the statically served files into a designated
- directory to be served up by the Apache web server as defined by
- ``STATIC_ROOT``.
-
-#. Test and/or use the Mysql integration with Toaster's Django web
- server. At this point, you can start up the normal Toaster Django
- web server with the Toaster database in Mysql. You can use this web
- server to confirm that the database migration and data population
- from the Layer Index is complete.
-
- To start the default Toaster Django web server with the Toaster
- database now in Mysql, use the standard start commands::
-
- $ source oe-init-build-env
- $ source toaster start
-
- Additionally, if Django is sufficient for your requirements, you can use
- it for your release system and migrate later to Apache as your
- requirements change.
-
-#. Add an Apache configuration file for Toaster to your Apache web
- server's configuration directory. If you are using Ubuntu or Debian,
- put the file here::
-
- /etc/apache2/conf-available/toaster.conf
-
-
- If you are using Fedora or RedHat, put it here::
-
- /etc/httpd/conf.d/toaster.conf
-
- If you are using OpenSUSE, put it here::
-
- /etc/apache2/conf.d/toaster.conf
-
- Following is a sample Apache configuration for Toaster you can follow:
-
- .. code-block:: apache
-
- Alias /static /var/www/toaster/static_files
- <Directory /var/www/toaster/static_files>
- <IfModule mod_access_compat.c>
- Order allow,deny
- Allow from all
- </IfModule>
- <IfModule !mod_access_compat.c>
- Require all granted
- </IfModule>
- </Directory>
-
- <Directory /var/www/toaster/poky/bitbake/lib/toaster/toastermain>
- <Files "wsgi.py">
- Require all granted
- </Files>
- </Directory>
-
- WSGIDaemonProcess toaster_wsgi python-path=/var/www/toaster/poky/bitbake/lib/toaster:/var/www/toaster/.local/lib/python3.4/site-packages
- WSGIScriptAlias / "/var/www/toaster/poky/bitbake/lib/toaster/toastermain/wsgi.py"
- <Location />
- WSGIProcessGroup toaster_wsgi
- </Location>
-
-
- If you are using Ubuntu or Debian, you will need to enable the config and
- module for Apache::
-
- $ sudo a2enmod wsgi
- $ sudo a2enconf toaster
- $ chmod +x bitbake/lib/toaster/toastermain/wsgi.py
-
- Finally, restart Apache to make sure all new configuration is loaded. For Ubuntu,
- Debian, and OpenSUSE use::
-
- $ sudo service apache2 restart
-
- For Fedora and RedHat use::
-
- $ sudo service httpd restart
-
-#. Prepare the systemd service to run Toaster builds. Here is a sample
- configuration file for the service:
-
- .. code-block:: ini
-
- [Unit]
- Description=Toaster runbuilds
-
- [Service]
- Type=forking User=toaster
- ExecStart=/usr/bin/screen -d -m -S runbuilds /var/www/toaster/poky/bitbake/lib/toaster/runbuilds-service.sh start
- ExecStop=/usr/bin/screen -S runbuilds -X quit
- WorkingDirectory=/var/www/toaster/poky
-
- [Install]
- WantedBy=multi-user.target
-
-
- Prepare the ``runbuilds-service.sh`` script that you need to place in the
- ``/var/www/toaster/poky/bitbake/lib/toaster/`` directory by setting
- up executable permissions::
-
- #!/bin/bash
-
- #export http_proxy=http://proxy.host.com:8080
- #export https_proxy=http://proxy.host.com:8080
- #export GIT_PROXY_COMMAND=$HOME/bin/gitproxy
- cd ~/poky/
- source ./oe-init-build-env build
- source ../bitbake/bin/toaster $1 noweb
- [ "$1" == 'start' ] && /bin/bash
-
-#. Run the service::
-
- $ sudo service runbuilds start
-
- Since the service is running in a detached screen session, you can
- attach to it using this command::
-
- $ sudo su - toaster
- $ screen -rS runbuilds
-
- You can detach from the service again using "Ctrl-a" followed by "d" key
- combination.
-
-You can now open up a browser and start using Toaster.
-
-Using the Toaster Web Interface
-===============================
-
-The Toaster web interface allows you to do the following:
-
-- Browse published layers in the `OpenEmbedded Layer
- Index <http://layers.openembedded.org>`__ that are available for your
- selected version of the build system.
-
-- Import your own layers for building.
-
-- Add and remove layers from your configuration.
-
-- Set configuration variables.
-
-- Select a target or multiple targets to build.
-
-- Start your builds.
-
-- See what was built (recipes and packages) and what packages were
- installed into your final image.
-
-- Browse the directory structure of your image.
-
-- See the value of all variables in your build configuration, and which
- files set each value.
-
-- Examine error, warning and trace messages to aid in debugging.
-
-- See information about the BitBake tasks executed and reused during
- your build, including those that used shared state.
-
-- See dependency relationships between recipes, packages and tasks.
-
-- See performance information such as build time, task time, CPU usage,
- and disk I/O.
-

-Additional Information About the Local Yocto Project Release
-------------------------------------------------------------
-
-This section only applies if you have set up Toaster for local
-development, as explained in the
-":ref:`toaster-manual/toaster-manual-setup-and-use:starting toaster for local development`"
-section.
-
-When you create a project in Toaster, you will be asked to provide a
-name and to select a Yocto Project release. One of the release options
-you will find is called "Local Yocto Project".
-
-.. image:: figures/new-project.png
- :align: center
- :scale: 75%
-
-When you select the "Local Yocto Project" release, Toaster will run your
-builds using the local Yocto Project clone you have in your computer:
-the same clone you are using to run Toaster. Unless you manually update
-this clone, your builds will always use the same Git revision.
-
-If you select any of the other release options, Toaster will fetch the
-tip of your selected release from the upstream `Yocto Project
-repository <https://git.yoctoproject.org>`__ every time you run a build.
-Fetching this tip effectively means that if your selected release is
-updated upstream, the Git revision you are using for your builds will
-change. If you are doing development locally, you might not want this
-change to happen. In that case, the "Local Yocto Project" release might
-be the right choice.
-
-However, the "Local Yocto Project" release will not provide you with any
-compatible layers, other than the three core layers that come with the
-Yocto Project:
-
-- `openembedded-core <http://layers.openembedded.org/layerindex/branch/master/layer/openembedded-core/>`__
-
-- `meta-poky <http://layers.openembedded.org/layerindex/branch/master/layer/meta-poky/>`__
-
-- `meta-yocto-bsp <http://layers.openembedded.org/layerindex/branch/master/layer/meta-yocto-bsp/>`__

-If you want to build any other layers, you will need to manually import
-them into your Toaster project, using the "Import layer" page.

-Building a Specific Recipe Given Multiple Versions
---------------------------------------------------
-
-Occasionally, a layer might provide more than one version of the same
-recipe. For example, the ``openembedded-core`` layer provides two
-versions of the ``bash`` recipe (i.e. 3.2.48 and 4.3.30-r0) and two
-versions of the ``which`` recipe (i.e. 2.21 and 2.18). The following
-figure shows this exact scenario:

-
-By default, the OpenEmbedded build system builds one of the two recipes.
-For the ``bash`` case, version 4.3.30-r0 is built by default.
-Unfortunately, Toaster as it exists, is not able to override the default
-recipe version. If you would like to build bash 3.2.48, you need to set
-the
-:term:`PREFERRED_VERSION`
-variable. You can do so from Toaster, using the "Add variable" form,
-which is available in the "BitBake variables" page of the project
-configuration section as shown in the following screen:
-
-.. image:: figures/add-variable.png
- :align: center
- :scale: 75%
-
-To specify ``bash`` 3.2.48 as the version to build, enter
-"PREFERRED_VERSION_bash" in the "Variable" field, and "3.2.48" in the
-"Value" field. Next, click the "Add variable" button:

-
-After clicking the "Add variable" button, the settings for
-``PREFERRED_VERSION`` are added to the bottom of the BitBake variables
-list. With these settings, the OpenEmbedded build system builds the
-desired version of the recipe rather than the default version:
