Hex and int Kconfig options are supposed to have defaults. This is so we
can configure U-Boot without having to enter particular values for the
items that don't have specific values in the board's defconfig file.
If this rule is not followed, then introducing a new Kconfig can produce
a loop like this:
Break things (BREAK_ME) [] (NEW)
Error in reading or end of file.
Break things (BREAK_ME) [] (NEW)
Error in reading or end of file.
The continues forever since buildman passes /dev/null to 'conf', and
the build system just tries again. Eventually there is so much output that
buildman runs out of memory.
We can detect this situation by looking for a symbol (like 'BREAK_ME')
which has no default (the '[]' above) and is marked as new. If this
appears multiple times in the output, we know something is wrong.
Add a filter function for the output which detects this situation. Allow
it to return True to terminate the process. Implement this termination in
cros_subprocess.
With this we get a nice message:
buildman --board sandbox -T0
Building current source for 1 boards (0 threads, 32 jobs per thread)

At present buildman does not write any output (to the 'out' and 'err)
files if the build terminates with a fatal error. This is to avoid adding
lots of spam to the logs.
However there are times when this is actually useful, such as when the

Currently, the following scenario will rebuild the first commit even
though it is not really necessary - the commit sha or the position in the
patchset did not change:
$ git am <local-patch-0001>
$ tools/buildman/buildman -P -E -W -b master mx6
<do some more development work>
$ git am <local-patch-0002>
$ tools/buildman/buildman -P -E -W -b master mx6 <- will rebuild the first
commit as well, even
though nothing has
changed about it.
This is due to the fact that previous results directories get removed
when the number of commits change. By removing the _of_#_ part of the

At present buildman defaults to running 'mrproper' on every thread before
it starts building commits for each board. This can add a delay of about 5
seconds to the start of the process, since the tools and other invariants
must be rebuilt.
In particular, a build without '-b', to build current source, runs much
slower without -I, since any existing build is removed, thus losing the
possibility of an incremental build.
Partly this behaviour was to avoid strange build-system problems caused by
running 'make defconfig' for one board and then one with a different
architecture. But these problems were fixed quite a while ago.
The -I option (which disabled mrproper) was introduced four years ago and
does not seem to cause any problems with builds.
So make -I the default and deprecate the option. To allow use of
'mrproper', add a new -m flag.

Notice that the first pattern has dashes throughout, while the second has

most toolchain tarballs is:

e.g.:
gcc-8.1.0-nolibc/aarch64-linux/
The first entry of the hexagon toolchain, however, is:
gcc-4.6.1-nolibc/
This causes the buildman logic in toolchain.py::ScanPath() to not be able to
find the "*gcc" executable since it looks in gcc-4.6.1-nolib/{.|bin|usr/bin}
instead of gcc-4.6.1/hexagon-linux/{.|bin|usr/bin}. Therefore when buildman
tries to download a set of toolchains that includes hexagon, the script fails.
This update takes the second line of the tarball unpacking (which works for

first two elements, separated by '/'. It makes this logic a bit more robust.

stdin to the build thread, which never comes. Eventually I suspect all the
