31 that before trying to make sense of this.
33 Buildman works by keeping the machine as busy as possible, building different
34 commits for different boards on multiple CPUs at once.
36 The source repo (self.git_dir) contains all the commits to be built. Each
37 thread works on a single board at a time. It checks out the first commit,
38 configures it for that board, then builds it. Then it checks out the next
39 commit and builds it (typically without re-configuring). When it runs out
40 of commits, it gets another job from the builder and starts again with that
43 Clearly the builder threads could work either way - they could check out a
44 commit and then built it for all boards. Using separate directories for each
45 commit/board pair they could leave their build product around afterwards
48 The intent behind building a single board for multiple commits, is to make
49 use of incremental builds. Since each commit is built incrementally from
50 the previous one, builds are faster. Reconfiguring for a different board
51 removes all intermediate object files.
53 Many threads can be working at once, but each has its own working directory.
54 When a thread finishes a build, it puts the output files into a result
57 The base directory used by buildman is normally '../<branch>', i.e.
58 a directory higher than the source repository and named after the branch
61 Within the base directory, we have one subdirectory for each commit. Within
62 that is one subdirectory for each board. Within that is the build output for
63 that commit/board combination.
65 Buildman also create working directories for each thread, in a .bm-work/
66 subdirectory in the base dir.
68 As an example, say we are building branch 'us-net' for boards 'sandbox' and
69 'seaboard', and say that us-net has two commits. We will have directories
72 us-net/ base directory

113 force_build: Force building even if a build already exists
114 force_config_on_failure: If a commit fails for a board, disable
115 incremental building for the next commit we build for that
116 board, so that we will see all warnings/errors again.

118 a previous run of buildman) is marked as failed, rebuild it.

132 incremental building, where buildman reconfigures on the first
133 commit for a baord, and then just does an incremental build for
134 the following commits. In fact buildman will reconfigure and
135 retry for any failing commits, so generally the only effect of
136 this option is to slow things down.
