With help from Max and Don, we now have a build script that:
1) Will not let you launch more than one build at a time
2) Will record _all_ the output of the script to the build log
3) Will fail if build, deployment, _or_ megatest fails
Summary status is still written to logs/nightly-log.txt (with
timestamps!)
The script is checked in to tools/trunk/build-tools/nightly/nightly-
go.sh. We should really make an effort to check changes in the build
server tools into svn. When I started to look at this, the copies on
the build server were out of date with svn and had a bunch of
conflicts that I had to resolve.
As a procedural matter, if you edit on the build server and have to
check in a change, please initial your comments, so we know _who_ was
svnbuild when the check-in was made.
