Another change in 1.1.2 that may bite people is that it introduces the
capability for rules to be multiline by allowing newlines inside a tag

newline will no longer terminate that bad rule, all rules follwoing it will
not be parsed (until it hits the next line with an uneven number of % on
the line)

Personally, I would probably concentrate on testing liblognorm-2.0 >>
and the upgrade process to it rather than spending much effort on
1.1.2
Well, liblognorm-1.1.1 to 1.1.2 is a *minor* bump according to the
version number.
This shouldn't require any test to be rewritten or break any software
which was working with liblognorm-1.1.1. If it does, it isn't a minor
bump and the version number/SONAME is wrong ;)
We bumped liblognorm because we thought it is just a bugfix release...
Regarding your first paragraph: You said "has a bad config"... if that
mean that the user wrote something which was violating specs but was
working due to a bug and now because the bug is fixed in v1.1.2 it will
break like it should from the beginning, that's ok. If it is a changed
behavior, it isn't OK.
by 'had a bad config', I'm meaning that it's a config that was bad in v1.1.1 and
earlier.
The difference is that in the earlier versions, each line was processed
individually, so a bad config only affected that line, following lines would
still work.
on 1.1.2 (and 2.0), multiline rules are allowed, and so lines that previously
were bad, but only affected that line, now trigger the multiline logic and so
rules after that no longer work.
so it's a config that violates specs that now causes more grief than before.

I created a PR (https://github.com/rsyslog/rsyslog/pull/492) which
enables mmnormalize in Travis to keep track.
