crecord: add an experimental option for space key to move cursor down

I really want to have an option of toggling a selection on a line and also
moving cursor down as a single keystroke. It also kinda makes sense for space
key to do this, because some other curses UIs in the wild do this (e.g. various
file managers, htop). So I got an idea to make a config option that defaults to
False for compatibility, but allows making crecord UI a lot more useful for
people with big hunks.

We add this an experimental option to experiment with this behavior.

Verify that pending changesets are seen by pretxn* hooks but not by other
processes that access the destination repo while the hooks are running.

The hooks (python and external) both reject changesets after some think time,
during which another process runs pull.  Each hook creates a file ('notify') to
indicate to the controlling process that it is running; the process removes the
file to indicate the hook can terminate.

init env vars

  $ d=`pwd`
  $ maxwait=20

utility to run the test - start a push in the background and run pull

  $ dotest() {
  >     rm -f notify
  >     printf 'push '; hg -R child-push tip --template '{node}\n'
  >     hg -R child-push -q push > push.out 2>&1 &
  > 
  >     # wait for hook to create the notify file
  >     i=$maxwait
  >     while [ ! -f notify -a $i != 0 ]; do
  >         sleep 1
  >         i=`expr $i - 1`
  >     done
  > 
  >     # run pull
  >     hg -R child-pull -q pull
  >     rc=$?
  > 
  >     # tell hook to finish; notify should exist.
  >     rm notify
  >     wait
  > 
  >     cat push.out
  >     printf 'pull '; hg -R child-pull tip --template '{node}\n'
  >     return $rc
  > }

python hook

  $ cat <<EOF > reject.py
  > import os, time
  > from mercurial import ui, localrepo
  > def rejecthook(ui, repo, hooktype, node, **opts):
  >     ui.write('hook %s\\n' % repo['tip'].hex())
  >     # create the notify file so caller knows we're running
  >     fpath = os.path.join('$d', 'notify')
  >     f = open(fpath, 'w')
  >     f.close()
  >     # wait for ack - caller should delete the notify file
  >     i = $maxwait
  >     while os.path.exists(fpath) and i > 0:
  >         time.sleep(1)
  >         i -= 1
  >     return True # reject the changesets
  > EOF

external hook

  $ cat <<EOF > reject.sh
  > printf 'hook '; hg tip --template '{node}\\n'
  > # create the notify file so caller knows we're running
  > fpath=$d/notify
  > touch \$fpath
  > # wait for ack - caller should delete the notify file
  > i=$maxwait
  > while [ -f \$fpath -a \$i != 0 ]; do
  >     sleep 1
  >     i=\`expr \$i - 1\`
  > done
  > exit 1 # reject the changesets
  > EOF

Test that pending on transaction without changegroup see the normal changegroup(
(issue4609)

  $ cat <<EOF > parent/.hg/hgrc
  > [hooks]
  > pretxnchangegroup=
  > pretxnclose = hg tip -T "tip: {node|short}\n"
  > [phases]
  > publishing=False

setup

  $ cd parent
  $ echo a > a
  $ hg add a
  $ hg commit -m a

actual test

  $ hg phase --public .
