serve: don't send any content headers with 304 responses
Fixes HTTP protocol violation introduced in
cf5c76017e11. 'hg serve' would show
a stacktrace when loading pages that not had been modified.
There was test coverage for this, but the wrong response headers wasn't shown
and thus not detected.
tests: fix doctest stability over Python versions
pprint ain't pretty in Python 2.4:
Changed in version 2.5: Dictionaries are sorted by key before the display is
computed; before 2.5, a dictionary was sorted only if its display required more
than one line, although that wasn’t documented.
Fixes issue introduced in
404feac78b8a.
convert: make toposort order stable when multiple orderings are possible
The output of some tests are changed. Not necessarily to the better, just other
valid permutations.
mq: stabilize update after strip of parent revision
Strip will (if it updates) update to the parent of revs[0], where revs are the
roots of the tree that is stripped.
When revs was list(set) it was thus undefined which root parent it would update
to. With sorted(set) it is at least stable what it updates to. (But it is very
possible that another more useful and predictable behaviour could be defined
... such as updating to the tip-most surviving wd ancestor.)
churn: sort users with same churn by name
This makes the output order well-defined and improves code readability.
