Happens to us all :(
Of course, as Rob suggested, a regression test suite means you don't _have_
to think so much about things that worked in the past. Not entirely so,
because your test suite is unlikely to cover every use case, but it should
help a lot.
We're a bit in the same boat - far too much of our system doesn't have test
suites, and even when we do test stuff there's inevitably something different
about production. At least we've moved to a relatively stable Debian based
infrastructure now where you can get pretty much an entire server running
with 'apt-get install fastmail-base; svn co $URL; make -C conf install'. Not
quite there yet, but that's the goal. Means we're testing in an environment
that's a much like production as we can make it and things don't get littered
with as many ad-hoc changes.
I hope my emergency patch is useful to you. I seems to have solved the
obvious symptoms for us. Of course you probably know better than me if
there's anywhere else that's generating index files that needs updating to
set that struct member.
Possibly a safer approach (bit late now, I know) is to have an init_index
function which is _always_ called on one of those structs _before_ you
do anything else to it, and then when you add a member to the struct you
only need to do the default case in one place (new_index.modseq = 1;).
That would have avoided the need to litter the code with bits of initialiser
everywhere. There's my object-oriented training talking.
We've moved most of our staff accounts (including me!) onto the server that
is running 2.3.5+patches so we can eat our own dogfood. Mmm.... dogfood.
Should help us see if anything else is strange.
(now I just have to figure things out so that when we move users we retain
the UIDVALIDITY so my entire offlineimap store doesn't get stale next time)
