patch: stop changing current directory before patching
_applydiff() patcher argument was added to help hgsubversion like extension
monkeypatching the patching process. While it could be removed at this point, I
prefer to leave it until patch.py is completely refactored and there is a valid
and tested alternative.
import os
from mercurial import hg, ui
u = ui.ui()
repo = hg.repository(u, 'test1', create=1)
os.chdir('test1')
# create 'foo' with fixed time stamp
f = open('foo', 'w')
f.write('foo\n')
f.close()
os.utime('foo', (1000, 1000))
# add+commit 'foo'
repo[None].add(['foo'])
repo.commit(text='commit1', date="0 0")
print "workingfilectx.date =", repo[None]['foo'].date()
