Yes, I have already thought about that and it's indeed the language
that is the problem with that approach. So I was thinking that if I
could catch the process waiting for input I could pick up the question
(since I know what it asks for and what form it has. Like: "Do you
want to continue [Y/n]?" Then let an 'OK' button or something feed the
upper case letter to stdin).
Ok, so I managed to isolate the yes or no option regardless of language.
But I can't seem to feed it correctly to the apt-get process. The code:
def readOutput(self):
outputString = QString(self.upgradeProcess.readStdout())
self.mainTextWindow.append(outputString)
# Check if upgradeProcess ask to continue
if outputString.endsWith("? "):
qApp.processEvents()
# Isolate the yes/ no characters needed for input.
yesOptionString = outputString.right(6)
yesOption = yesOptionString.left(1)
noOptionString = outputString.right(4)
noOption = noOptionString.left(1)
answer = yesOption # Temporary setting answer for testing.
Will be replaced by user input.
self.mainTextWindow.append(answer) # Temporary to verify answer
# Feed answer to stdin
if answer == yesOption:
self.mainTextWindow.append("This is the yesOption!!") #
Temporary just to verify that Y is isolated
self.upgradeProcess.writeToStdin(yesOption)
## self.upgradeProcess.writeToStdin(chr(121)) #No difference
else:
self.mainTextWindow.append("This is the noOption!!") #
Temporary just to verify that Y is isolated
self.upgradeProcess.writeToStdin(noOption)
self.upgradeProcess.closeStdin()
ouputString = " "
I do feed 'something' that apt-get recieves because it aborts. It would
not have done that unless it got a response of some sort. But even if I
replace the 'yesOption' with the letter "y" it still just aborts. So I'm
thinking that either I don't know how to properly write to stdin (a
distinct posibility) or apt-get uses some other program/ process/
interface to handle user interaction.
I have tried looking for clues in apt's sourcecode but C++ is really not
my cup of tea so I'm still stuck. And I'm running out of ideas...
So if anyone have an idea I'd really appreciate it.
