I've just updated mercurial to 2.7 in /hipster. It works for me...
And fails for anyone other.
Yesterday I tried to identify the error. So far, didn't find it. It
seems I'll have less free time in the next days, so, here I'd like to
summarize my findings if someone would like to dive into it.
1) Any recent mercurial version (2.5,2.6,2.7) fails to pass its tests
when built with python 2.6. Mercurial 2.7 built with Python 2.4 seems to
be more adequate. It fails only 5 tests from its testsuite. Mercurial
2.7 built with Python 2.6 fails 8 tests of 12, then tests hang. The
reason is that hg server process throws exception in one of the tests.
127.0.0.1 - - [29/Aug/2013 18:42:57] Exception happened during
processing request '/a/atom-log':

AttributeError: 'list' object has no attribute 'next'
The code is:
202 def changelist(latestonly, **map):
203 revs = []
204 if pos != -1:
205 revs = web.repo.changelog.revs(pos, 0)
206 if latestonly:
207 revs = (revs.next(),)
208 curcount = 0
209 for i in revs:
210 ctx = web.repo[i]
It seems that revs received on 205 line is empty.
I bet that this exception is just a symptom and the reason that hg
either creates incorrect repositories or can't correctly commit to them...
2) I suspect it to be an issue with our Python - at least with 2.4
mercurial works. I've examined Python build logs. Found several rather
unpleasant warnings about pointers casting, but it seems these warnings
are not related to this particular problem. Looked for some core dumps
or incorrect *.so files (we already had such experience - Python build
system doesn't detect such errors), but didn't find them...
