Do we have any plan to make sys.buildnumber meaningful in the releases as well (generally compiled from an svn export, as Michael pointed out), or are we happy with a broken number in this case?

I'm actually a bit confused that Barry changed the meaning of "build number" for that feature. The build number was meant to count builds, not revisions (whether this is a useful feature or not).

So I would argue that it is "broken" when it is the result of svnversion, and "good" when it actually counts builds.

It stopped counting builds on Windows quite some time ago; perhaps it is best to drop the build number entirely?

Should I propose / check-in a patch to expose sys.buildinfo instead ("CPython", "41761", "trunk"), as this got positive feedback so far? It's also less surprizing than the current sys.buildnumber, which is a string despite its name.

Propose first. I have the feeling that the feature will change forth and back if everybody gets to say something. I would call it sys.svnversion (because that's what it is).

What to put in in case of tagged builds is then yet another question.

Regards, Martin
