Pythonista 3.4 several problems

DavinE

Hello all,

My iPhone unfortunately installed the Pythonista 3.4 update today which I didn't really want to do....
I now have several problems which I hope to solve with you as soon as possible!

first I get an error message like this:
SyntaxWarning: "is" with a literal. Did you mean "=="?
Code:

If (i + 1) % 200 is 0 and querry_size > 205:

what does that mean before everything had worked ?

Stash
when I try to run pip install mysql.connector in Stash I get the following error:
TypeError("unsuppoertd operand type(s) for +: 'OmniClass' and 'list'")
Failed to run setup.py
Fall back to directory guessing ...
Error: cannot locate packages. Manual installation required.

how can I fix this ?

view error...
I have a SafeAreaView as "main view" when I open it now with the Py 3.10 the app just closes without error message....

what I have now already tried from "which" point in the code the error occurs and that would be from said code:

set_menu(self.button_variable [
    self.showSetting,
    self.hideSetting,
], long_press=True)

i found out with sys.exit() that it crashes from this code but i don't know why :(

I hope we can get this back somehow need the app for work :(

SyntaxWarning: "is" with a literal

This is intentional: https://bugs.python.org/issue43151. Also, it's not an error, so the code still works. However, you should really be using == for equality comparison here. One of the few "valid" uses of is seems to be checking whether an object is None like thing is None.

Not sure about the other ones, though.

As @ForceBru says, the fix for 1. is simple…

If (i + 1) % 200 is 0 and querry_size > 205: —>
If (i + 1) % 200 == 0 and querry_size > 205:

Python 3.10 raises this warning (not an error) on all platforms (not just Pythonista) because identity is not the same thing as equality in Python.

>>> a = "Python"
>>> a += "ista"
>>> b = "Pythonista"
>>> a == b
True
>>> a is b
False
>>> id(a), id(b)

For 2., there are compatibility issues with staSH but that utility is from https://github.com/ywangd/stash and is not built into Pythonista. Please open pull requests or issues there until compatibility with the current Pythonista is restored. I have done this as well but I am not a maintainer of that repo so I cannot merge changes.

For 3., you might try https://omz-software.com/pythonista/docs-3.4/py3/ios/ui.html#ui.in_background

If that does not help then try to create the shortest program possible (ideally 4 or 5 lines) that crashes and post that here so we can all see the crash.

@DavinE Did you check the content of file _objc_exception.txt in Pythonista local root after the crash?

@ccc, @ForceBru, Thanks for that 👍

@ccc does not worked for me... 😭
here is a example which crashes:

import ui
from anchors import SafeAreaView, dock, At, at, size_to_fit
from ui3.menu import set_menu, Action
from ui3.sfsymbol import SymbolImage

class crash(SafeAreaView):
    def __init__(self):
        self.main_content = ui.View(frame=self.bounds, flex='WH')
        self.add_subview(self.main_content)
        
        self.button_area = ui.View(name='button_area')
        dock(self.button_area).bottom(self.main_content, At.TIGHT)
        at(self.button_area).height = at(self.button_area).fit_height
        
        self.name = 'test'
        self.background_color = 'blue'
        self.present('fullscreen', hide_title_bar=True)
        
        self.test()
    def test(self):
        button_1 = size_to_fit(ui.Button(name='button_1'))
        button_1.image = ui.Image('iow:ios7_people_32')
        button_1.width = button_1.height
        dock(button_1).bottom_left(self.button_area)
        at(self.button_area).height = at(self.button_area).fit_height
        
        open_view = Action('Einstellungsseite aufrufen', self.nothing, image=SymbolImage('gear'))
        close_view = Action('Einstellungsseite nicht aufrufen', self.nothing, image=SymbolImage('gear'))
        close_view.selected = True
        
        set_menu(button_1, [
            open_view,
            close_view,
        ], long_press=True)

    def nothing(self):
        pass

if __name__ == '__main__':
    crash()

I don't get this file 😭

@DavinE you have this error. To get this info, you have to use faulthandler from @dgelessus see here

Is @mikael still active ?
in github ?

cvp

@DavinE Yes, he has answered today to an issue I posted in his WkWebView

But segmentation error is often not easy to solve.

Okay already once a good news but at the same time a bad if these errors are not easy to remove 🙈

cvp

@DavinE cool, be optimistic

DavinE

@cvp, Must I otherwise I have a tearing problem

because of my problem with mysql.connector i have to wait too or here is no quick solution ?

cvp

@DavinE problem seems to come from objc_util, if you check the fautlog, thus more for @omz
