revsetlang: do not pass in non-bytes to parse()...

revsetlang: do not pass in non-bytes to parse() Since parse() isn't a simple function, we shouldn't expect it would raise TypeError or ValueError for invalid inputs. Before, TypeError was raised at 'if pos != len(spec)', which was quite late to report an error. This patch also makes tokenize() detect invalid object before converting it to a py3-safe bytes. Spotted while adding the 'revset(...)' hack to _parsewith().

      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!

        rollback completed

        abort: pretxncommit hook exited with status 1
