cmdserver: forcibly use L channel to read password input (
issue3161)
Command server is designed to use the channel protocol even if the server
process is accessible to tty, whereas vanilla hg should be able to read
password from tty in that case. So it isn't enough to swap sys.stdin:
# works only if the server process is detached from the console
sys.stdin = self.fin
getpass.getpass('')
sys.stdin = oldin
or test isatty:
# vanilla hg can't talk to tty if stdin is redirected
if self._isatty(self.fin):
return getpass.getpass('')
else:
...
Since ui.nontty flag is undocumented and command-server channels don't provide
isatty(), this change won't affect the other uses of ui._isatty().
issue3161 also suggests to provide some context of messages. I think it can
be implemented by using the generic templating function.
