2 How To Add Your Build Configuration To LLVM Buildbot Infrastructure
3 ===================================================================
8 This document contains information about adding a build configuration and
9 buildbot-worker to private worker builder to LLVM Buildbot Infrastructure.
14 There are two buildmasters running.
16 * The main buildmaster at `<http://lab.llvm.org:8011>`_. All builders attached
17 to this machine will notify commit authors every time they break the build.
18 * The staging buildbot at `<http://lab.llvm.org:8014>`_. All builders attached
19 to this machine will be completely silent by default when the build is broken.
20 Builders for experimental backends should generally be attached to this
23 Steps To Add Builder To LLVM Buildbot
24 =====================================
25 Volunteers can provide their build machines to work as build workers to
28 Here are the steps you can follow to do so:
30 #. Check the existing build configurations to make sure the one you are
31 interested in is not covered yet or gets built on your computer much
32 faster than on the existing one. We prefer faster builds so developers
33 will get feedback sooner after changes get committed.
35 #. The computer you will be registering with the LLVM buildbot
36 infrastructure should have all dependencies installed and you can
37 actually build your configuration successfully. Please check what degree
38 of parallelism (-j param) would give the fastest build. You can build
39 multiple configurations on one computer.
41 #. Install buildbot-worker (currently we are using buildbot version 2.8.5).
42 Depending on the platform, buildbot-worker could be available to download and
43 install with your package manager, or you can download it directly from
44 `<http://trac.buildbot.net>`_ and install it manually.
46 #. Create a designated user account, your buildbot-worker will be running under,
47 and set appropriate permissions.
49 #. Choose the buildbot-worker root directory (all builds will be placed under
50 it), buildbot-worker access name and password the build master will be using
51 to authenticate your buildbot-worker.
53 #. Create a buildbot-worker in context of that buildbot-worker account. Point it
54 to the **lab.llvm.org** port **9990** (see `Buildbot documentation,
56 <http://docs.buildbot.net/current/tutorial/firstrun.html#creating-a-worker>`_
57 for more details) by running the following command:
61 $ buildbot-worker create-worker <buildbot-worker-root-directory> \
63 <buildbot-worker-access-name> \
64 <buildbot-worker-access-password>
66 To point a worker to silent master please use lab.llvm.org:9994 instead
69 #. Fill the buildbot-worker description and admin name/e-mail. Here is an
70 example of the buildbot-worker description::
73 Core i7 (2.66GHz), 16GB of RAM
75 g++.exe (TDM-1 mingw32) 4.4.0
78 Microsoft(R) 32-bit C/C++ Optimizing Compiler Version 16.00.40219.01 for 80x86
80 #. Make sure you can actually start the buildbot-worker successfully. Then set
81 up your buildbot-worker to start automatically at the start up time. See the
82 buildbot documentation for help. You may want to restart your computer
85 #. Send a patch which adds your build worker and your builder to
86 `zorg <https://github.com/llvm/llvm-zorg>`_. Use the typical LLVM
87 `workflow <https://llvm.org/docs/Contributing.html#how-to-submit-a-patch>`_.
89 * workers are added to ``buildbot/osuosl/master/config/workers.py``
90 * builders are added to ``buildbot/osuosl/master/config/builders.py``
92 Please make sure your builder name and its builddir are unique through the
95 It is possible to allow email addresses to unconditionally receive
96 notifications on build failure; for this you'll need to add an
97 ``InformativeMailNotifier`` to ``buildbot/osuosl/master/config/status.py``.
98 This is particularly useful for the staging buildmaster which is silent
101 #. Send the buildbot-worker access name and the access password directly to
102 `Galina Kistanova <mailto:gkistanova@gmail.com>`_, and wait till she
103 will let you know that your changes are applied and buildmaster is
106 #. Check the status of your buildbot-worker on the `Waterfall Display
107 <http://lab.llvm.org:8011/#/waterfall>`_ to make sure it is connected, and
108 ``http://lab.llvm.org:8011/#/workers`` to see if administrator contact and
109 worker information are correct.
111 #. Wait for the first build to succeed and enjoy.
