I think the problem is worse with 1.6. At least I myself was
absolutely not looking forward to testing another release of 1.6 (but
did it anyway, after a week or so of waiting). As you say, setting up
a build environment for Subversion on Windows is already pretty hard.
But then, if you have your build env finetuned for building trunk
and/or 1.7, going back to build 1.6 is a real pain:
- Can't build out of the box with VS 2010, because gen-win.py on 1.6.x
only generates up to 2008 format (so you either have to do it with VS
2008 if you still have it (I didn't ... recently uninstalled it), or
you "convert" it from 2008 format to 2010 format from within the VS
2010 GUI (which takes a long time). I know, maybe I could have
backported the necessary stuff to 1.6.x, but ... I didn't.
- Can't build with latest serf on Windows, as I noted in the signing
thread. That took me a couple of iterations before reverting back to
serf 0.7.1.
- Running the test suite with 1.6 takes a looooong time on Windows.
It's at least twice as slow as the 1.7 testsuite on my laptop. I start
a .bat file calling the 4 combinations in sequence (local, svn, neon,
serf) before going to sleep, and in the morning it's still only
halfway the neon run (with the serf run still coming up). This is
probably mostly a testament to the performance improvement that WC-NG
brought to 1.7, especially for Windows/NTFS. But then it's doubly
painful to see this slow 1.6 running on my laptop ... ouch that hurts,
don't want to go there again :-).
I think maybe we could lower the required number of sigs for 1.6 (or
for whichever release is the one-before-eol'ed version). It should be
very stable by now, the backports are very conservative and there are
few of them, and probably the number of users that will install it is
also declining...
