Summary: Stability in wikipedia.py

Initial Comment:
Recently I've had some problems with the stability of 'wikipedia.put(...)' sometimes this method had some issues and that killed my bot.
I was able to track the problem down to 'wikipedia._getEditPage(...)' and following code (in 'wikipedia.py' around line 725):

********************************
        while not textareaFound:
            text = self.site().getUrl(path, sysop = sysop)

            if text.find("<title>Wiki does not exist</title>") != -1:
                raise NoSuchSite(u'Wiki %s does not exist yet' % self.site())
********************************

and I have changed it that way, to hold my bot/script running:

********************************
        while not textareaFound:
            try:
                text = self.site().getUrl(path, sysop = sysop)
            except:
                time.sleep(1)
                continue

            if text.find("<title>Wiki does not exist</title>") != -1:
                raise NoSuchSite(u'Wiki %s does not exist yet' % self.site())
********************************

and I am "pretty" sure that this solved my problem. :)

Probably you are also intressted in this solution?! I would assume that the delay of 1sec is neither critical nor needed.

...I could add some code to print the exception the next time, my bot is
down...?!

Hello back!

I have to apologize because I don't have the error message anymore (I had
it once...) and the error is a bit hard to reproduce, since it is not
thrown very often... :(
You are right; my solution is a kind of "brute-force"... :) Yesterday,
after my first postings, I had a look into 'getUrl', since I was
remembering that it should catch (and did this in the past accordingly)
such kind of problems. What was strange; the error I had occurred
instantaneously after calling 'getUrl', without any time delay... And it
was (most of the time) on the toolserver, which might have another kind of
internet connection and therefore another failure behaviour (and throw
other exceptions)...?!

Hello !

Are you able to elaborate on what error was raised? There is probably a
nicer way to catch the error, at a lower level, instead of bluntly retrying
on error =)
