Beta Status Update

polymerchm

Hooked up to my Mac and used XCODE to look for a crash report. None.

(Thought I had posted this before...)

I manually imported jedi and tried to get a code completion on one of the problematic spots. At some point it ends up in an infinite recursion loop, until the interpreter throws an exception due to exceeding the recursion limit. Why exactly this happens I can't say though.

polymerchm

An off switch would be nice. This was not a problem (in 1.5). @degelessus: Which version of jedi did you try? The installed jedi in 1.6 is 0.9.0. Perhaps a rollback to 0.8.1?

@polymerchm It seems that only crash reports with file names ending in ".ips" are shown in Xcode. Those that have been transferred are renamed on the device to ".ips-transferred" or similar. Those from the Pythonista beta end in ".ips-beta" or so. Fortunately, they call all be viewed on the device, if you go to Settings -> Privacy -> Diagnosis ... -> Diagnosis ... (or something close to that).

polymerchm

@OMZ Do you automatically get crash logs, or can I send them to you? Will sync device tonight and see if I have logs relevant to the autocomplete bug (now that I know where to find them).

I've found an issue where editor.make_new_file() causes the app to crash. It doesn't seem to matter what arguments I pass to it the app just shuts down.

polymerchm

works fine for me (iOS 8.3, beta 1.6).

import editor

editor.make_new_file('test.py','this is a test')

create a file in the root directory each time its run, adding a number to the end to avoid a duplicate name.

I love the updates!!! especially tabs and search. Also love the purplish theme. And most of all love the improved traceback readout. And the consolidated keyboard is a great idea.

Great job OMZ you've created the premier development platform for (on) iOS!

Just an observation - the yellow dot to the left of "Pythonista" under the icon doesn't go away for me. I believe it's supposed to indicate that there's a new version of the app on your device that you haven't opened yet...but I have. Pythonista is the only app I have in test flight so forgive me if I'm wrong - either way sounds like it would be a test flight issue.

Also one gripe - if you have a script in the foreground and it runs, you can click the x in the upper right while in console view to stop it. You can't press play(run) from the same place - instead it's a greyed out x and you have to backup to the script to press play again. It wasn't like this in previous versions, and while I can see the logic in making sure you're at the script before you can run it, being able to run a script multiple times while looking at the console without backing out of it is very useful to quickly try code modifications out during development...for me at least. Perhaps a toggle for this functionality deserves to exist in settings?

Thanks again.

ALSO, since the new version I get this error all the time. Everything still works, but this error shows up in red in the console.

I believe the yellow dot means the app is in testing/beta state.

The lack of a run button on the console is explained in the Beta readme and/or in a post above.

The insecure platform thing is tied to new security checks in the requests module.

Just another bug report (maybe it's just me doing everything wrong) for the sk module:

Here is the code I'm using:

                # if exceeded life, reduce alpha by 1
                p.alpha -= decayrate
                if p.alpha <= 0:
                    p.run_action(sk.Action.call(p.remove_from_parent))
    
    def touch_began(self, node, touch):
        self.selected = None
        new = particle_tpl.__copy__()
        new.position = touch.location
        new.physics_body.velocity = randvec(MAXSPD)
        new.color = (random.random(), random.random(), random.random())

        self.touch_began(node, touch)
    
    def did_begin_contact(self, collison):
        # Make the color change on collison
        collison.body_a.node.color = (random.random(), random.random(), random.random())
        collison.body_b.node.color = (random.random(), random.random(), random.random())

def main():
    game = Game()

    scene_view.shows_node_count = True
    scene_view.present()
    return game

if __name__ == '__main__':
    g = main()

It's similar to the old Particles example, however using physics. I'm running into two problems:

No matter what I do, I can't make the sk.LightNode() do anything.
In did_begin_contact, I'm getting the following error:

AttributeError: 'NoneType' has no attribute 'color'

It says in the docs that the collison.body_a.node attribute should be the node it is attached to, but for me it seems to be just None.

omz

@misha_turnbull It looks like both issues are caused by bugs in sk.Node.__copy__. Try setting the lighting_bit_mask attribute manually after creating the copy. To make the contact callback work properly, you'd probably need to create a new PhysicsBody instead of relying on the one that gets copied along with the node. I'm looking into this. One other thing: If you want to make your physics bodies "immovable", set dynamic to False instead of pinned to True.

techteej

I must say, after being out of the Python world for a while, this makes me very excited to get back in!!

mteep

@omz There seems to be some issue affecting the canvas module. In both the recent betas (160013 and 160014), your turtle.py example crashes Pythonista immediately. But other simple canvas usage does not. In released versions like 1.5, and the earlier betas, I have only observed canvas crashes when I edited the script while it was running.

ccc

https://github.com/cclauss/pythonista-module-versions is still throwing warnings on requests calls in 160014.

omz

@ccc I mentioned in the release notes why I rolled back to an older version of requests.

ccc

I read that but Pythonista_module_versions.py is still throwing warnings like it would if you did NOT roll back the version of requests.

Requests is indeed fairly current according to Pythonista_module_versions.py:

| module        | local    | PyPI       |
| name          | version  | version    |
| ------------- | -------- | ---------- |
| requests      | 2.6.0    | 2.6.2      |

omz

Hmm, looks like something went wrong in my deployment script, should be 2.5.1.

dgelessus

This has been a problem for a looong time, but I never got around to reporting it: in the interpreter input field you cannot use the tab key on an external keyboard. It probably tries to switch to the next input field instead, which does nothing, because there is no other input field.

polymerchm

P.S. No Watch folder. Not that I am buying a watch. I did the Testflight install over the previous beta, not fresh.

misha,
regarding your issue.
new = particle_tpl.copy() #does not correctly copy the physics body.
new.physics_body = particle_tpl.physics_body.copy() #should fix your problem.
