hgweb.manifest: revno of manifest and changelog aren't always the same
In the v4l-dvb repo, the manifest revno and the changelog revno are not
in sync. This happened because the same patch was applied to the same
revision in two different branches, resulting in the same manifest text,
with the same parents and so the first revision was reused.
Since hgweb.manifest was assuming the revnos of the manifest and of the
changelog were always the same, clicking on manifest -> bz2 in the
v4l-dvb site would download the wrong revision.
Use the linkrev to go from manifest revision to changelog revision.
This still won't be perfect since the page will still talk about
"manifest for changeset XYZ", where XYZ was the first changeset to have
this manifest, which is not necessarily the same changeset that the user
clicked to get to this page - but at least the contents will be the
same.

#!/bin/sh # # 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' -d '1000000 0' echo >> foo hg commit -m 'change foo' -d '1000001 0' hg log -r 0: cat >> test.py << EOF from mercurial import changelog, util 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 = util.opener(*args) def wrapper(*a): f = o(*a) return singlebyteread(f) return wrapper cl = changelog.changelog(opener('.hg')) print cl.count(), 'revisions:' for r in xrange(cl.count()): print short(cl.node(r)) EOF python test.py
