parsers: incrementally parse the revlog index in C
We only parse entries in a revlog index file when they are actually
needed, and cache them when first requested.
This makes a huge difference to performance on large revlogs when
accessing the tip revision or performing a handful of numeric lookups
(very common cases). For instance, "hg --time tip --template {node}"
on a tree with 300,000 revs takes 0.15 before, 0.02 after.
Even for revlog-intensive operations (e.g. running "hg log" to
completion), the lazy approach is about 1% faster than the eager
parse_index2.

b51a8138292a introduced a regression where we would mention in the changelog executable files added by the second parent of a merge. Test that that doesn't happen anymore $ "$TESTDIR/hghave" execbit || exit 80 $ hg init repo $ cd repo $ echo foo > foo $ hg ci -qAm 'add foo' $ echo bar > bar $ chmod +x bar $ hg ci -qAm 'add bar' manifest of p2: $ hg manifest bar foo $ hg up -qC 0 $ echo >> foo $ hg ci -m 'change foo' created new head manifest of p1: $ hg manifest foo $ hg merge 1 files updated, 0 files merged, 0 files removed, 0 files unresolved (branch merge, don't forget to commit) $ hg ci -m 'merge' this should not mention bar: $ hg tip -v changeset: 3:ef2fc9b4a51b tag: tip parent: 2:ed1b79f46b9a parent: 1:d394a8db219b user: test date: Thu Jan 01 00:00:00 1970 +0000 description: merge $ hg debugindex bar rev offset length base linkrev nodeid p1 p2 0 0 5 0 1 b004912a8510 000000000000 000000000000
