[IronPython] SCons on IronPython 2.0B2

[Dino Viehland]

Generally speaking the more information we have about a bug the better we can make the call on it.  The most important thing I'd suggest adding is what scenario the bug is blocking.  For example if you reported 5 Trac related bugs and 5 SCons related bugs and we fixed 3 Trac bugs and 2 SCons bugs that might not be quite as useful as fixing 5 SCons bugs.  So just identifying the scenario will help us drive end-to-end scenarios to completion rather than fixing a bunch of random bugs which might not end up enabling anything!

But in general some insight into how we triage bugs might be useful.  Generally speaking we 1st prioritize bugs in the core runtime - that includes the parser, compiler, and core data types.  Basically anything in IronPython.dll and everything in IronPython.Modules.dll gets a lower priority.  Part of that is that we want to be as true to the core language as possible and therefore those fixes are viewed as more important.  The other part of that is that we hope to open up IronPython.Modules.dll and allow user contributions.

>From there I'd say the next thing we look at is votes and priority.  Votes are of course easy to understand - I'd suggest sending your bug reports to the mailing list as well so that you can get that number bumped up.  I'm guessing not everyone is subscribed to the RSS feed of IronPython bug reports like I am so it's likely that people don't see the issues even if they'd be interested in seeing them get fixed.  Priority is of course harder to understand.  I already mentioned modules which we tend to look at as a lower priority.  We also tend to look at negative scenarios (e.g. exception messages, wrong exception, etc...) as having a lower priority - sometimes that's the wrong call as certain frameworks have heavy reliance upon the negative scenarios working correctly.  From there it's largely a gut-call based upon what everyone sitting around doing the triage thinks.  Usually if anyone thinks we should raise the priority we do - so on that point I'd suggest indicating what priority you think the bug should have as well.  If everyone always said high priority we'd be back to coming up w/ the levels entirely ourselves but if discretion is used we'd likely respect the proposed priorities.

Finally I don't know how much being set to 2.1 matters.  The real release to watch out for is Future.  Those are bugs we don't think we can get to anytime soon due to deep architectural issues.  If something's been moved to 2.1 then it's more the case that we think this can wait and that's an easy decision to reverse.

Hi Dino,
Yeah, _winreg is what's missing. Good to hear that it will be coming soon!

Not every bug I've filed is related to SCons (some are Trac-related,
and maybe even a couple from elsewhere). I've just been testing random
apps (primarily WSGI-enabled webapps), seeing what breaks, and filing
bugs.

What's the best way to push up the priority of a bug? Codeplex
comments? Mailing list? I know of a few that are set for 2.1 that I'd
like to see sooner.

-Jeff
