largefiles: fix confusion upon removal of added largefile (issue3176)
This patch makes "hg remove" work the same way on largefiles as it does on
regular Mercurial files. If you try to remove an added largefile, the removal
fails and you are instead prompted to use "hg forget" to undo the add.
import os

from mercurial.util import atomictempfile
# basic usage
def test1_simple():
if os.path.exists('foo'):
os.remove('foo')
file = atomictempfile('foo')
(dir, basename) = os.path.split(file._tempname)
assert not os.path.isfile('foo')
assert basename in glob.glob('.foo-*')
file.write('argh\n')
file.close()
assert os.path.isfile('foo')
assert basename not in glob.glob('.foo-*')
print 'OK'
# discard() removes the temp file without making the write permanent
def test2_discard():
if os.path.exists('foo'):
os.remove('foo')
file = atomictempfile('foo')
(dir, basename) = os.path.split(file._tempname)
file.write('yo\n')
file.discard()
assert not os.path.isfile('foo')
assert basename not in os.listdir('.')
print 'OK'
# if a programmer screws up and passes bad args to atomictempfile, they
# get a plain ordinary TypeError, not infinite recursion
