hook: disable demandimport before importing hooks
This solved an obscure bug for me. In upgrading Distribute on the server, a
patch was added to has a try: import a except ImportError thing that's only
supposed to work with Python 3.3. I'm using 2.7. My hook failed with an
ImportError because of this. It seems kind of sensible to turn off
demandimport before importing the hook, since the except ImportError pattern
is used quite a bit in Python code (including in other Distribute code).
import os
from mercurial import hg, ui, merge
u = ui.ui()
repo = hg.repository(u, 'test1', create=1)
os.chdir('test1')
def commit(text, time):
repo.commit(text=text, date="%d 0" % time)
def addcommit(name, time):
f = open(name, 'w')
f.write('%s\n' % name)
f.close()
repo[None].add([name])
commit(name, time)
def update(rev):
merge.update(repo, rev, False, True, False)
def merge_(rev):
merge.update(repo, rev, True, False, False)
