The behavior is intentional.  It could save the log somewhere, or it could direct you to use build-dumprendertree to debug the failure,or print the output if passed --verbose.  NRWT is intentionally much more sparse in output than ORWT.

Keeping with the "show the minimum needed for the common case" philosophy, do you have a preference between telling folks to debug with build-dumprendertree, or pass --verbose, or spewing the log only on failure?

[Simon Fraser (smfr)]

Spew the log only on failure. It needs to show up on the bots too.

[Adam Roben (:aroben)]

I'd recommend spewing when --verbose is passed or when the build fails, even if --verbose was not passed.

It would be great to fix this so we can investigate bug 73326.

[Adam Roben (:aroben)]

I'm going to take a stab at this.

LGTM.  Thanks!
