57 Welcome to the Yocto Project Test Environment Manual!
58 This manual is a work in progress.
59 The manual contains information about the testing environment
60 used by the Yocto Project to make sure each major and minor
61 release works as planned.
62 Other organizations can leverage off the process and testing
63 environment used by the Yocto Project to create their own
64 automated, production test environment.
65 </p><p>
66 Currently, the Yocto Project Test Environment Manual has no
67 projected release date.
68 This manual is a work-in-progress and is being initially loaded
69 with information from the README files and notes from key
70 engineers:

75 is not maintained.
76 However, some information from this README file still
77 applies but could need some modification.
78 In particular, information about setting up headless
79 sanity tests and build history.
80 The sections on these will be changing.

93 is the main README for Yocto Project Autobuilder.
94 The <code class="filename">yocto-autobuilder2</code> repository

101 is a valid Autobuilder Git repository that contains
102 Yocto Project Autobuilder Helper Scripts.
103 The <code class="filename">yocto-autobuilder-helper</code>
104 repository contains the "glue" logic that connects any
105 Continuous Improvement (CI) system to run builds,
106 support getting the correct code revisions, configure
107 builds and layers, run builds, and collect results.
108 The code is independent of any CI system, which means
109 the code can work Buildbot, Jenkins, or others.
110 </p></li></ul></div><p>
111 </p></div><div class="section" title="1.2. Yocto Project Autobuilder Overview"><div class="titlepage"><div><div><h2 class="title" style="clear: both" id="test-yocto-project-autobuilder-overview">1.2. Yocto Project Autobuilder Overview<span class="permalink"><a alt="Permalink" title="Permalink" href="#test-yocto-project-autobuilder-overview">¶</a></span></h2></div></div></div><p>
112 The Yocto Project Autobuilder collectively refers to the software,
113 tools, scripts, and procedures used by the Yocto Project to test
114 released software across supported hardware in an automated and
115 regular fashion.
116 Basically, during the development of a Yocto Project release, the
117 Autobuilder tests if things work.
118 The Autobuilder builds all test targets and runs all the tests.
119 </p><p>
120 The Yocto Project uses the unpatched
121 <a class="ulink" href="https://docs.buildbot.net/0.9.15.post1/" target="_top">Buildbot Nine</a>
122 to drive its integration and testing.
123 Buildbot Nine has a plug-in interface that the Yocto Project
124 customizes using code from the
125 <code class="filename">yocto-autobuilder2</code> repository.
126 The resulting customized UI plug-in allows you to
127 visualize builds in a way suited to the project.
128 </p><p>
129 A "helper" layer provides configuration and job management
130 through scripts found in the
131 <code class="filename">yocto-autobuilder-helper</code> repository.
132 The helper layer contains the bulk of the build configuration
133 information and is release-specific, which makes it highly
134 customizable on a per-project basis.
135 The layer is CI system-agnostic and contains a number of helper
136 scripts that can generate build configurations from simple JSON
137 files.
138 </p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3>
139 It is possible to use the outer layers from another
140 Continuous Integration (CI) system such as
141 <a class="ulink" href="https://en.wikipedia.org/wiki/Jenkins_(software)" target="_top">Jenkins</a>
142 instead of Buildbot.

361 The following is going to be the replacement content for the
362 section on "Nightly Builds".
363 Not sure what we are going to call these builds.
364 We need a name to replace "Nightly Builds".
365 </p><p>
366 Here is the content from Richards email:
367 </p><pre class="literallayout">
368 In 1.6, we actually dropped the "nightly" bit pretty much everywhere.
369 They are now named MACHINE or MACHINE-DISTRO, e.g. qemuarm or qemuarm-
370 lsb (which tests poky-lsb with qemuarm). We now parallelise not just
371 architecture but by machine so machine and real hardware are now
372 separate. The flow is therefore to build the images+sdks, then test the
373 images+sdks, trying to do as much as possible in parallel.
374
375 We have two types of build trigger, "quick" and "full". quick runs all
376 the things which commonly fail and one random oe-selftest. "full" runs
377 all our targets, runs oe-selftest on all distros and includes ptest and
378 build performance tests. Its slower but more complete and would be used
379 for release builds.

382 This section is created from the information in the
383 <code class="filename">yocto-autobuilder2</code> 
384 <a class="ulink" href="http://git.yoctoproject.org/clean/cgit.cgi/yocto-autobuilder2/tree/README.md" target="_top"><code class="filename">README.md</code></a>
385 file.
386 I am making an assumption that we do not want to refer to the
387 Autobuilder stuff as "Autobuilder2".
388 My guess is that since this is the first documentation of any
389 automated test environment and process in the Yocto Project
390 user documentation, we will treat it as the start of things.
391 </div><p>
392 Automatic testing is based on the workers executing builds using
393 Buildbot Nine configured for specific build jobs triggered in an
394 automatic and regular fashion.
395 Worker Configuration and triggering is accomplished through
396 the
397 <a class="ulink" href="http://git.yoctoproject.org/clean/cgit.cgi/yocto-autobuilder2/tree/" target="_top">Yocto Project Autobuilder layer</a>
398 and a set of
399 <a class="ulink" href="http://git.yoctoproject.org/clean/cgit.cgi/yocto-autobuilder-helper/tree" target="_top">helper scripts</a>.
400 </p><p>
401 The configuration and helper scripts have as little code and
402 as few custom Buildbot extensions as possible.
403 The configuration collects required input from the user to
404 furnish the helper scripts with the input needed for workers
405 to accomplish their builds.
406 The input consists of minimal user-customizable parameters
407 used to trigger the helper build scripts.
408 </p><p>
409 Each builder maps to a named configuration in the helper
410 scripts.
411 The configuration is created with the steps and properties
412 required to invoke the helper scripts for a worker's builds.
413 </p><p>
414 Each worker has a custom scheduler created for it and contains
415 parameters configured for the scheduler that can supply the custom
416 versions of the required values for the helper script parameters.
417 </p><p>
418 Following is the code layout for the Autobuilder:
419 </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>

425 Implements functionality related to
426 <a class="ulink" href="https://www.mediawiki.org/wiki/MediaWiki" target="_top">MediaWiki</a>.
427 The <code class="filename">wikilog</code> plug-in uses this
428 functionality.
429 Effectively, this functionality provides helper functions
430 for the plug-in.
431 </p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3>
432 Much of this code can be replaced by porting the

476 The goal is to keep custom code minimized throughout the
477 Autobuilder.
478 The few customizations implemented support the Yocto Project
479 Autobuilder Helper Script workflows and help replicate the
480 workflows established with the Yocto Autobuilder layer.
481 In particular, the following files accomplish this customization:

490 Steps to deploy the Yocto Project Autobuilder assume each target
491 system has a copy of Buildbot installed.
492 Additionally, various pieces of functionality require that a copy
493 of the Autobuilder Helper Scripts (i.e.
494 <code class="filename">yocto-autobuilder-helper</code>) is available
495 in the home directory at
496 <code class="filename">~/yocto-autobuilder-helper</code> of the user
497 running Buildbot.
498 </p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3>
499 If you are using a reverse proxy, be aware that modern
500 Buildbot uses a web socket for various communications between
501 the master and the web's User Interface.
502 Refer to the
503 <a class="ulink" href="http://docs.buildbot.net/latest/manual/cfg-www.html#reverse-proxy-configuration" target="_top">Buildbot documentation</a>

650 The production Yocto Autobuilder uses a cluster of build
651 workers.
652 The cluster shares the same
653 <a class="ulink" href="http://www.yoctoproject.org/docs/2.6/ref-manual/ref-manual.html#var-SSTATE_DIR" target="_top"><code class="filename">SSTATE_DIR</code></a>

656 through an NFS4 mounted Network Attached Storage (NAS).
657 The main nightly trigger pre-populates the
658 <code class="filename">DL_DIR</code>, which allows the workers to not
659 have to deal with a lot of downloading.
660 In theory, you could also run your build workers with
661 <a class="ulink" href="http://www.yoctoproject.org/docs/2.6/ref-manual/ref-manual.html#var-NO_NETWORK" target="_top"><code class="filename">NO_NETWORK</code></a>
662 to enforce a single point for populating
663 <code class="filename">DL_DIR</code>.
664 </p><p>
665 Running multiple build workers is fairly simple, but does require
666 some setup:
667 </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>
668 Ensure the settings in
669 <code class="filename">autobuilder.conf</code> are valid
670 for each worker.
671 Certain variables are set within this file that
672 work with the local configurations on each
673 worker.
674 </p></li><li class="listitem"><p>
675 Within
676 <code class="filename">yocto-controller/controller.cfg</code>,
677 add your worker to the
678 <code class="filename">c['workers']</code> list inside
679 the <code class="filename">BUILDWORKERS</code> section.
680 </p></li><li class="listitem"><p>
681 For each worker change the
682 <code class="filename">WORKER SETTINGS</code> section
683 of
684 <code class="filename">yocto-worker/buildbot.tac</code>
685 to match the settings in
686 <code class="filename">controller.cfg</code>.
687 </p></li><li class="listitem"><p>
688 Workers must reside in the same path as the
689 Build Controller, even if they are on
690 completely different machines.

693 Build History is used to track changes to packages and
694 images.
695 By default, the Autobuilder does not collect build history.
696 The production Autobuilder does have this functionality
697 enabled.
698 </p><p>
699 Setting up build history requires the following
700 steps:
701 </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>
702 Create an empty Git repository.
703 Make a single commit to it and then create and
704 push branches for each of the nightly core
705 architectures (i.e.. mips, ppc, x86...).
706 </p></li><li class="listitem"><p>
707 Find a central location to create a clone for the
708 repository created in the previous step.
709 This works best if you have a setup similar to
710 the production Autobuilder (i.e. NAS with many
711 workers).
712 </p></li><li class="listitem"><p>
713 Run the following:

793 The helper scripts work in conjunction with the Yocto Project
794 Autobuilder.
795 These scripts do the actual build configuration and execution
796 for tests on a per release basis.
797 </p><p>
798 You can use <code class="filename">pre-commit-hook.sh</code> to verify
799 the JSON file before committing it.
800 Create a symbolic link as follows:
801 </p><pre class="literallayout">
802 $ ln -s ../../scripts/pre-commit-hook.sh .git/hooks/pre-commit
803 </pre><p>
804 </p><p>
805 Most users will have to customize the helper script repository
806 to meet their needs.
807 The repository is located at
808 <a class="ulink" href="http://git.yoctoproject.org/clean/cgit.cgi/yocto-autobuilder-helper" target="_top">http://git.yoctoproject.org/clean/cgit.cgi/yocto-autobuilder-helper</a>.
809 The scripts themselves should be more generically reusable.
810 The <code class="filename">config.json</code> is less reusable as it
811 represents the Yocto Project Autobuilder test matrix.
812 </p><p>
813 Two customization options are possible: 1) variable substitution,
814 and 2) overlaying configuration files.
815 The standard <code class="filename">config.json</code> minimally attempts
816 to allow substitution of the paths.
817 The helper script repository includes a
818 <a class="ulink" href="http://git.yoctoproject.org/clean/cgit.cgi/yocto-autobuilder-helper/tree/local-example.json" target="_top"><code class="filename">local-example.json</code></a>
819 to show how you could override these from a separate configuration
820 file.
821 Pass the following into the environment of the autobuilder:
822 </p><pre class="literallayout">
823 ABHELPER_JSON="config.json local-example.json"
824 </pre><p>
825 As another example, you could also pass the following into the
826 environment:
827 </p><pre class="literallayout">
828 ABHELPER_JSON="config.json /some/location/local.json"
829 </pre><p>
