11 | <para>This section details how the project tests changes, through automation on the | ||
12 | Autobuilder or with the assistance of QA teams, through to making releases.</para> | ||
13 | |||
14 | <para>The project aims to test changes against our test matrix before those changes are | ||
15 | merged into the master branch. As such, changes are queued up in batches either in the | ||
16 | <filename>master-next</filename> branch in the main trees, or in user trees such as | ||
17 | <filename>ross/mut</filename> in <filename>poky-contrib</filename> (Ross Burton | ||
18 | helps review and test patches and this is his testing tree).</para> | ||
19 | <para>We have two broad categories of test builds, including "full" and "quick". On the | ||
20 | Autobuilder, these can be seen as "a-quick" and "a-full", simply for ease of sorting in | ||
21 | the UI. Use our Autobuilder console view to see where me manage most test-related items, | ||
22 | available at: <link linkend="" | ||
23 | >https://autobuilder.yoctoproject.org/typhoon/#/console</link>.</para> | ||
24 | <para>Builds are triggered manually when the test branches are ready. The builds are | ||
25 | monitored by the SWAT team. For additional information, see <link linkend="" | ||
26 | >https://wiki.yoctoproject.org/wiki/Yocto_Build_Failure_Swat_Team</link>. If | ||
27 | successful, the changes would usually be merged to the <filename>master</filename> | ||
28 | branch. If not successful, someone would respond to the changes on the mailing list | ||
29 | explaining that there was a failure in testing. The choice of quick or full would depend | ||
30 | on the type of changes and the speed with which the result was required.</para> | ||
31 | <para>The Autobuilder does build the <filename>master</filename> branch once daily for | ||
32 | several reasons, in particular, to ensure the current <filename>master</filename> branch | ||
33 | does build, but also to keep <filename>yocto-testresults</filename> (<link linkend="" | ||
34 | >http://git.yoctoproject.org/cgit.cgi/yocto-testresults/</link>), buildhistory | ||
35 | (<link linkend="">http://git.yoctoproject.org/cgit.cgi/poky-buildhistory/</link>), | ||
36 | and our sstate up to date. On the weekend, there is a master-next build instead to | ||
37 | ensure the test results are updated for the less frequently run targets.</para> | ||
38 | <para>Performance builds (buildperf-* targets in the console) are triggered separately every | ||
39 | six hours and automatically push their results to the buildstats repository at: <link | ||
40 | linkend="">http://git.yoctoproject.org/cgit.cgi/yocto-buildstats/</link>. </para> | ||
41 | <para>The 'quick' targets have been selected to be the ones which catch the most failures or | ||
42 | give the most valuable data. We run 'fast' ptests in this case for example but not the | ||
43 | ones which take a long time. The quick target doesn't include *-lsb builds for all | ||
44 | architectures, some world builds and doesn't trigger performance tests or ltp testing. | ||
45 | The full build includes all these things and is slower but more comprehensive.</para> | ||

49 | <title>Release Builds</title> | ||
50 | |||
51 | <para>The project typically has two major releases a year with a six month cadence in April | ||
52 | and October. Between these there would be a number of milestone releases (usually four) | ||
53 | with the final one being stablization only along with point releases of our stable | ||
54 | branches.</para> | ||
55 | <para>The build and release process for these project releases is similar to that in <link | ||
56 | linkend="test-daily-devel">Day to Day Development</link>, in that the a-full target | ||
57 | of the Autobuilder is used but in addition the form is configured to generate and | ||
58 | publish artefacts and the milestone number, version, release candidate number and other | ||
59 | information is entered. The box to "generate an email to QA"is also checked.</para> | ||
60 | <para>When the build completes, an email is sent out using the send-qa-email script in the | ||
61 | <filename>yocto-autobuilder-helper</filename> repository to the list of people | ||
62 | configured for that release. Release builds are placed into a directory in <link | ||
63 | linkend="">https://autobuilder.yocto.io/pub/releases</link> on the Autobuilder which | ||
64 | is included in the email. The process from here is more manual and control is | ||
65 | effectively passed to release engineering. The next steps include:<itemizedlist> | ||

68 | the results will be available.</para> | ||
