subrepo: add the parent context to hgsubrepo
This brings parity with gitsubrepo and svnsubrepo (which already reference their
parent), and will be used in an upcoming patch.
I'm a bit concerned that the parent context could get stale (consider what
happens when the parent repo is reverted for example). I tried adding the
parent context to the substate tuple so that the parent is available everywhere
a state change is possible, but that made submerge() unhappy. Even with
removing the parent context inside submerge(), I wasn't able to get all of the
test diffs fixed.
But since the other subrepos reference their parent too, if there is a problem,
it is a preexisting one (that nobody seems to be running into). It can be fixed
if/when it pops up.

revlog.parseindex must be able to parse the index file even if an index entry is split between two 64k blocks. The ideal test would be to create an index file with inline data where 64k < size < 64k + 64 (64k is the size of the read buffer, 64 is the size of an index entry) and with an index entry starting right before the 64k block boundary, and try to read it. We approximate that by reducing the read buffer to 1 byte. $ hg init a $ cd a $ echo abc > foo $ hg add foo $ hg commit -m 'add foo' $ echo >> foo $ hg commit -m 'change foo' $ hg log -r 0: changeset: 0:7c31755bf9b5 user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: add foo changeset: 1:26333235a41c tag: tip user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: change foo $ cat >> test.py << EOF > from mercurial import changelog, scmutil > from mercurial.node import * > > class singlebyteread(object): > def __init__(self, real): > self.real = real > > def read(self, size=-1): > if size == 65536: > size = 1 > return self.real.read(size) > > def __getattr__(self, key): > return getattr(self.real, key) > > def opener(*args): > o = scmutil.opener(*args) > def wrapper(*a): > f = o(*a) > return singlebyteread(f) > return wrapper > > cl = changelog.changelog(opener('.hg/store')) > print len(cl), 'revisions:' > for r in cl: > print short(cl.node(r)) > EOF $ python test.py 2 revisions: 7c31755bf9b5 26333235a41c $ cd ..
