Just to clarify: for several teams,
Tuesday will be a public holiday and hence they will do their testing on
Monday.

Those are test candidate builds which
will be needed by those testing on Monday. All components are required
to submit their latest work to those builds, so that the teams testing
on Monday have good and up-to-date builds.

---

Here is a summary of the build schedule
we will follow for M7's "final week", as discussed in status
call today.
 
I will update the calendar [1] as well, but thought I'd post here, in prose,
in case I misunderstood -- plus, I am going to add a small wrinkle. 

For warm-ups, we'll build Thursday morning, and Friday morning, and Sunday
evening. 

We will schedule builds 3 times per day on Monday and 3 times per day on
Wednesday, with Tuesday being full test day. After Wednesday, will be on-demand
for blocking/critical bug or regression fixes. 

In all cases, the 4.2 builds will be scheduled first, and then the 3.8
builds scheduled 2 hours later [we'd normally expect identical (or near
identical) input, it is just offset so as to not swamp the build machine
and signing queues].

Morning builds will be at 8 AM Eastern (for 4.2) and 10 AM Eastern (for
3.8) 
Evening builds will be a 6 PM, and 8 PM, for 4.2 and 3.8. 
Midday builds will be at 1 PM and 3 PM, for 4.2 and 3.8. 

We may need to adjust as we get the unit tests running and see how they
impact Hudson's overall utilization. Perhaps build/test 3.8 once per day,
or something. 

The N-builds will be turned off for this final week, starting Saturday
(that is Friday nightly will be the last one). 

The wrinkle: it occurred to me after the status meeting, is that I would
like to turn on the "3 times per day schedule" (maybe more?)
on Saturday and Sunday. BUT, still only take the final one on Sunday as
the one official one to promote to "downloads" and leaving the
others on build machine, unless someone requests otherwise. I want to do
this to get a few runs through the parts of our automated scripts which
are supposed to say "no changes detected, the such-and-such scheduled
build was canceled". It might take a few passes to get that just right
 [2]. So, I hope at least a few of those times over the weekend, in
fact, no one will make any changes! :)  (or, if I really get into
it, I might "simulate" by scheduling one for every hour or so,
for testing).  So, Saturday and Sunday you might seeing some odd messages
about scheduled builds being cancelled, or I builds being started or completed,
but I'll try to figure out a way to divert those to test mail (though,
I failed at that last time I tried). 

If anyone has any corrections or questions, let me know.
