For those of you watching balsa, our memory leak tinderbox, just a quick heads up that we’ll soon be migrating to the virtualized balsa[s] very soonishly.
The new virtual memory leak tinderboxen names are balsa-trunk which, coincidentally enough, does trunkish builds, and balsa-18branch which does—you guessed it—Firefox 1.8 branch builds.
bz and I looked at the numbers for both the physical and virtual tinderboxen and they looked comparable/cogent/good. Because these are leak memory tests, the virtaulized versions of these tinderboxen don’t seem to be affected by virtualization, which we expected.
If you’d like to take a gander at these new tinderboxen, check out the 1.8 branch page and the trunk tinderbox page.
(They’re also publishing to the Seamonkey-Ports page, but for some reason, both physical- and virtual-balsa are in various states of unhappiness… which, on the one hand, is good news in terms of validating that the VMs are coherent images of the physical machines, but bad in that… they’re both broken.)
Because physical-balsa is literally sitting on the colo floor and the ever-gallant IT peeps are tripping over the machine, we’ll probably shut it down within the next few days. If there’s a reason why we shouldn’t, please let us know.

Tidbit the First:
The current Build Team Radars have been posted on wiki.m.o.
I did say radars—multiple—as we’ve published August’s monthly radar, but also a longer term, quarterly radar.
Astute readers of the two scopes may notice that the monthly radars now have ETA dates, whereas they didn’t before. You may also note that the quarterly radar has no specific dates, but has a ninth month outlook.
Being the aviation geek that I am, don’t be surprised if your hear me start referring to these as the “[Monthly] Approach” and the “[Quarterly] Center” radars1

rhelmer has been spending his days working on the Test-Only Tinderboxen. For those in a hurry, this was adding functionality to tinderbox to download a build and test it on a separate machine. These machines would have different characteristics than the build machines (namely, they wouldn’t be VMs), and hopefully will give us more stable data.
Well, they’re finally here! Look for columns ending in “test perf” on Linux and Windows on the 1.8 branch and trunk Tinderbox pages. And this is only phase one.
Thanks, rhelmer, for your hard work on this!

Tidbit the third:
We made this change some time ago, but it may still be confusing: nightly builds older than about about 60 days now get moved to archive.m.o, and moved off of ftp.m.o.
If you’re looking for older nightlies than you can find on ftp.m.o, check out archive.
____________________
1 Approach radar has different requirements than Center radar: in Approach’s airspace, the planes are moving slower and the precision requirements for the radar data is higher (due to higher congestion in the airspace). So, less airspace to cover, but more detailed information necessary. Center radar, on the other hand, covers a much larger area, and the planes are moving in multiples of Mach, so there’s a larger space, but less precise positioning data. An apt analogy for our radars, I think.

While doing some testing today, we found a serious bug that will probably have to be addressed before Beta 2 ships.
It has to do with the migration code just barfing on large amounts of input.
As Rob Strong notes, it’s currently unclear whether or not it’s a blocker, but I wouldn’t be surprised if it turned out to be. The attachments have some pretty disconcerting screenshots in them, as does the test URL noted in the bug.
I know sspitzer is working on investigating it more; expect a complete writeup soonishly.
