Currently, if a build is slow, you only get debug output after an hour.
This is to allow for uncluttered output. If output is too cluttered, it's hard
to distinguish regular output from errors.
The problem with this approach is that it's often hard to debug why the build
is slow. Now that Chrome builds by default, it takes over an hour to build,
and people see little indication as to why. You can show the output with
build_packages --showoutput, but that is often too verbose and clutters the
output too much.
Here's an example log snippet that is hard to debug:
Pending 2, Ready 0, Running 1, Retrying 0, Total 22 [Time 5m20.5s Load 3.69 3.04 2.66]
Pending 2, Ready 0, Running 1, Retrying 0, Total 22 [Time 5m25.5s Load 3.40 2.99 2.65]
... yada yada yada ...
Pending 2, Ready 0, Running 1, Retrying 0, Total 22 [Time 45m32.9s Load 1.00 1.18 2.95]
From the above output, we see that a package is building for a long time, but
we don't know what package. We should output the package name every two minutes
at least so people know what package is taking so long. That's what this change
implements.
BUG=chromium-os:8575
TEST=Confirmed new status appear for regular build_packages. Confirmed
build_packages --showoutput is unchanged.
