Windows buildfarm support, or lack of it

From

What's wrong with this picture?

http://www.pgbuildfarm.org/cgi-bin/show_status.pl

Notice how all the red is at the bottom of the report?  That's because
all the Windows machines are at the bottom, indicating that they haven't
reported recently.  AFAICT, snake is the only Windows machine that
actually runs the buildfarm on a regular schedule, and even it is just
running once a day.  So, while the timescale for finding out if a commit
breaks or fixes other platforms is just a couple hours, we generally
need a full day to find out about Windows.  For a platform that requires
as much special-case care and feeding as the Windows code does, that's
not very acceptable.  For a platform that's as ubiquitous as Windows
allegedly is, that's pretty surprising.  You'd think we could find a
couple of people willing to run buildfarm tests every four hours or
so, as many of the Unix buildfarm members do.

(Yeah, I'm a bit ticked off after waiting overnight to find out if
yesterday's commits fixed Windows, and getting up to find no new
data.)

For my part the difficulty is scheduling.  As a primarily unix user I 
understand cron, but have no idea what the windows equivalent is.  For my 
cygwin buildfarm member I setup cron, but the make step failed for every 
build for unknown reasons while succeeding if not run from cron.  That 
further demotivated me from scheduling mingw builds.  Perhaps snake's 
maintainer could share his configuration?

I can bump that up as high as you'd like within reason. 4? 6 times a day?

I have spare licences for most versions of Windows as well, so if Microsoft's virtual server product is not too
expensivefor us I can probably add a few platform variations to that box. I'll look into it.

I run a simple batch script that fires the run off under msys from the Windows Task Scheduler. I'll happily help out
anyonewho wants to get a build running.

There is job schedulers for Windows. I have no idea how good or bad they 
are.

In fact MS released Virtual PC 2004 for free a couple days ago

Let's go for 6, at least for HEAD. Under normal use buildfarm doesn't 
actually do anything unless it detects a change in the source, and it 
makes sure there isn't a collision by using a lockfile. That means it is 
safe to schedule builds fairly frequently.

There's probably no need to check the back branches oftener than once a
day, but if you can do HEAD every 4 hours that'd be great ...

Yeah - I have licences for it, but it's more of an interactive emulator. I think I'll need the server version to run
fullyunattended.

Andrew, Tom:

I'm putting a solicitation in this week's PWN for more Windows buildfarm 
members.  With 250,000 Windows+PostgreSQL users out there, you'd think a few 
people would step up.

Dave, I think you may need to give Andrew Windows buildfarm instructions to 
put up at www.pgbuildfarm.org.

I will have seahorse doing Windows builds at the same rate then ...

Sure. It's pretty simply. I run one for each branch (used to do one for
all runs, but a problem in an early run can prevent later ones running
at all then

Surely we can dredge up enough Windows users that Dave need not futz
with putting multiple versions onto his one machine ...

This might help: http://support.microsoft.com/default.aspx?scid=kb;en-us;308569&sd=tech The windows scheduler is ok. I think Dave is doing it the best way.

It seems that VMWare are following suit - their entry level VMWare
Server is now free for Windows and Linux :-)

It has been for some time, at least in Beta, so I'm not sure who really 
went first.

We should be supplying a sample applicance for VMware server that 
showcases our stuff - maybe the LiveCD project guys could do that?

Try setting a more complete $PATH; there's a good chance that make  
isn't able to find something it needs.

FWIW, Virtual Server 2005 R2 Enterprise Edition (how's that for a
product name) is also a free download from MS (provided you have a
license for the underlying OS, but since it runs only on Win2k3, what'd
they expect..)
