I created an editcounter in class ReplaceRobot of replace.py and was disappointed with my counter not listening to the failure of put_async.

Now I created a callback function:
    def lacika(self, page, err):
        if err is None:
            print u'%s saved successfully' % page.title() #for debug
        else:
            print 9999999
            self.editcounter -= 1
            print self.editcounter

Note that this is not thread safe (or maybe it is due to the GIL - but it could happen self.editcounter changes between reading it, subtracting one, and writing it back).

Now I ran four tests:
1. Successful save, it's OK.
2. After loading the page, while replace.py waits for my choice, I protected the page. Result:
1 page was changed. <-- message from main process
Updating page [[Szerkesztõ:BinBot/semmi]] via API
9999999 <-- just a test message from callback
0 <-- New self.editcounter, correct, but too late

What is exactly the problem here? This is exactly the expected behaviour: it runs the callback /after/ the page has been saved. It's not a time machine. If you need to have an exact editcount during the main loop, use .put(). Alternatively, move your logic into the callback function - that is the only place where the correct information is available.

Here comes my first problem. As far as I understood, I should use join to make the main process wait for put_async. But put_asyn is taken from wikipedia.py. How can I use join here, where should I write it? Could someone write a simple example to make the bot wait for put_async?

Why would you want to join() the thread? The bot always waits for all save operations to finish.

4th test: After loading the page, while the bot is waiting for my choice, I delete the page. This seems to be a bug:
1 page was changed.
Updating page [[Szerkesztõ:BinBot/semmi]] via API
Unknown Error. API Error code:missingtitle
Information:The article you tried to edit doesn't exist
Szerkeszt<:BinBot/semmi saved successfully

So did it re-create the page? or...?

Best,
