hg: acquire wlock while updating the working directory via updatetotally...

hg: acquire wlock while updating the working directory via updatetotally updatetotally() might be invoked outside wlock scope (e.g. invocation via postincoming() at "hg unbundle" or "hg pull"). In such case, acquisition of wlock is needed for consistent view, because parallel "hg update" and/or "hg bookmarks" might change working directory status while executing updatetotally(). Strictly speaking, truly consistent updating should acquire also store lock, because active bookmark might be moved to another one outside wlock scope (e.g. pulling from other repository causes updating current active one). Acquisition of wlock in this patch ensures consistency in as same level as past "hg update".

      Corrupt an hg repo with a pull started during an aborted commit

      Create two repos, so that one of them can pull from the other one.

        $ hg init source

        $ cd source

        $ touch foo

        $ hg add foo

        $ hg ci -m 'add foo'

        $ hg clone . ../corrupted

        updating to branch default

        1 files updated, 0 files merged, 0 files removed, 0 files unresolved

        $ echo >> foo

        $ hg ci -m 'change foo'

      Add a hook to wait 5 seconds and then abort the commit

        $ cd ../corrupted

        $ echo "[hooks]" >> .hg/hgrc

        $ echo 'pretxncommit = sh -c "sleep 5; exit 1"' >> .hg/hgrc

      start a commit...

        $ touch bar

        $ hg add bar

        $ hg ci -m 'add bar' &

      ... and start a pull while the commit is still running

        $ sleep 1

        $ hg pull ../source 2>/dev/null

        pulling from ../source

        transaction abort!
