completion: add a debuglabelcomplete command
When completing a "label" (a symbolic name for a commit), the
bash_completion script currently has to invoke hg three times. For
a large repository, the cost of starting up and loading all the
necessary context over and over is very high.
For instance, in mozilla-central:
time (export HGPLAIN=1; hg tags -q; hg bookmarks -q; hg branches) >/dev/null
0.446 sec
Compare with the debuglabelcomplete command that this commit adds:
time hg debuglabelcomplete >/dev/null
0.148 sec
This greatly helps responsiveness.

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 create repos $ hg init parent $ hg clone -q parent child-push $ hg clone -q parent child-pull $ echo a > child-push/a $ hg -R child-push add child-push/a $ hg -R child-push commit -m a -d '1000000 0' test python hook $ cat <<EOF > parent/.hg/hgrc > [extensions] > reject = $d/reject.py > [hooks] > pretxnchangegroup = python:reject.rejecthook > EOF $ dotest push 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b hook 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b transaction abort! rollback completed abort: pretxnchangegroup hook failed pull 0000000000000000000000000000000000000000 test external hook $ cat <<EOF > parent/.hg/hgrc > [hooks] > pretxnchangegroup = sh $d/reject.sh > EOF $ dotest push 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b hook 29b62aeb769fdf78d8d9c5f28b017f76d7ef824b transaction abort! rollback completed abort: pretxnchangegroup hook exited with status 1 pull 0000000000000000000000000000000000000000
