Useful tip: put DMAKE_OUTPUT_MODE=TXT2 in your environment, and dmake
will
spit out the build output serially. This means that there will be long
gaps between spurts of output into the log, but it makes the resulting
log
much more readable.
Doesn't sound like this would have any impact on the actual build time
so any reason why nightly shouldn't make this the default ?
It could also speed up highly parallel builds over nfs. I have noticed
considerable contention on the home-grown nfs rwlock for the
nightly.log file when building with aggressive max jobs (like 64-128);
at one stage I changed some nightly environment variable that
influenced the log to accumulate in /tmp - it's copied to the
log dir at the end, anyway.
