Re: Windows: core.useBuiltinFSMonitor without core.untrackedcache - performance hazard?

Hi Jeff,

We're currently looking at a problem that we believe is in the
untracked-cache code.  This is causing some of our Scalar tests
to fail on Windows when the untracked-cache is turned on.  This
is independent of whether FSMonitor or FSCache is turned on.
We're still tracking this down.

And yes, the best possible solution is to turn on FSMonitor *and*
the untracked-cache, so that the "untracked" status code doesn't
have to do anything.  So I want to look at tracking down the above
problem before doing anything else.

I got a bit excited about a possible clean path forward to getting
-uall to work well with untracked cache, and submitted a patch along
those lines, but rereading the above I should probably have been a
little more patient.

Is there anything "we" can do to see/understand the
scalar-test-suite-error you describe above, or is this
microsoft-internal?

Thanks
