Xcode Template for Pythonista
I am trying to upload a Pythonista project to the Apple App Store.
I have tried many, many time and keep getting code signing errors.
I am using Xcode 8.2.1
So this is what I have done:
Started with new Xcode Swift single view project, archived it and was able to submit it to the App Store. So my certificates are all working. I downloaded the Xcode template and then archived it. When I submit to Apple, it hangs on the code signing for a really long time and then comes back with this error:
ERROR ITMS-90035: "Invalid Signature. Code object is not signed at all. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target. For more information, please consult https://developer.apple.com/library/ios/documentation/Security/Conceptual/CodeSigningGuide/Introduction/Introduction.html"
The only thing I can figure out is that it seems to be trying to code sign the PythonistaKit.framework and does not seem to be able to. I can see "PythonistaKit.framework (0 Entitlements), just before I validate it.
Wondering if anyone else is able to reproduce this error, or even better have a fix to the problem.
Thanks. Will give it a try and test an upload to TestFlight too.
Here's the re-worked script, which throws as many of those dummies at the top of each file as it needs to stop the madness.
EDIT: There are some problems with this method as well, as it bounces the lines indicating the encoding style, which breaks a bunch of stuff... I ended up having to regex replace them back to the top, but will work this script out to do it better later. Just be aware that this will happen!
# Change these: pylib_path1 = '/path/to/PythonistaKit.framework/pylib' pylib_path2 = '/path/to/PythonistaKit.framework/pylib_ext' import shutil import os import subprocess def check_is_executable(file_path): file_output = subprocess.check_output(['file', file_path]) if 'executable' in file_output: return True, file_output return False, file_output def fix_executable(file_path): with open(file_path, 'r') as f: source = f.read() with open(file_path, 'w') as f: f.write('#\input texinfo\n' + source) is_executable, out = check_is_executable(file_path) return not is_executable def fix_pylib(pylib_path, dry_run=False): for path, dirs, files in os.walk(pylib_path): for filename in files: full_path = full_path = os.path.join(path, filename) is_executable, file_output = check_is_executable(full_path) if is_executable: extension = os.path.splitext(full_path).lower() if extension == '.py' or extension == '.pym' or filename == 'command_template': if dry_run: print '### Executable found: %s' % (filename,) else: print 'Fixing %s...' % (filename,) fixed = False counter = 0 while not fixed: fixed = fix_executable(full_path) counter = counter + 1 print 'Fixed with '+str(counter)+' dummy lines.' else: print '### Executable found, but does not seem to be Python code: %s' % (full_path,) if __name__ == '__main__': fix_pylib(pylib_path1) fix_pylib(pylib_path2)```
Hi @sreyemnayr, just tried your script, but still getting an error on upload to app store. Any other ideas or refinements to your script?
I'm making a bit of progress:
- My original error related to the future.py file in pylib, after running the script the Xcode error changed.
- I noticed that after running the above script the specific file that I was getting the 'Invalid Signature' error on had change to pylib/compiler/init.py. I had a look at that file and it didn't have a #\input texinfo up the top so I added it manually.
- I then reran the script and the error changed to pylib/compiler/ast.py This did have lots of #\input texinfo, so I copy and pasted all of them to double the amount of #\input texinfo lines at the top of the file. This seemed to satisfy Xcode.
- I then reran the script and the error changed one of the files in pylib/ctypes/test. I just deleted the whole pylib/ctypes/test folder.
- I than reran the script and the error changed to pylib/dateutil/READEME. I deleted the README file and the NEWS file while I was at it.
- I than reran the script and the error changes to pylib/site-packages/dropbox/init.py. As I'm not using dropbox in my app I just deleted the dropbox folder.
- I then had errors on pylib/site-packages/twitter.py, webbrowser.py, xmltodict.py and ui.py. They all had just one #\input texinfo line so I inserted an extra 1000 #\input texinfo lines at the top of each.
- I then had remaining errors in the files in pylib_ext/ so I added about #\input texinfo lines at the top of each.
- Finally my app submitted successfully!!!!
I must confess I really don't understand all of this. Feels like there's got to be a better way....
Thanks to @sreyemnayr for posting the script as I would not have solved this without it.
@peterdougstuart any chance you would be willing to share your updated template?
@sreyemnayr could you please update your script to work in Python 3?
if extension == '.py' or extension == '.pym' # can be shortened to: if extension in ('.py', '.pym')
Sorry for delay responding....
Happy to share @RomSpy, but please note that my templates have been minimized to my project i.e. deleted lots of modules I'm not using. Therefore it may not work for your project. You might be better off following the principles of steps I outlined above.
If you are still interested in my templates can you send me a PM on twitter (same handle as here) and I'll send you a zip or something. Alternatively point me to somewhere I can upload the files and I'll do so.
@peterdougstuart thank you for the offer. I ended up doing what you did and removing everything I wasn't using and then running the script above. I was able to successfully update my app in the store using that method in addition to your added steps. Thanks again.
Hi, i am interested in your templates which is submitted to itunesConnect successfully, can you send me a zip ?
Hi @xino386 can you PM on twitter and I’ll send you a zip of my scripts (same handle as here). Note that my scripts have been trimmed down to match the subset of the libraries used in my app so you might be better off following the steps above to get it to work.
I have a succes storey with your fix script (June 19/18). Here’s what I did. Pasted approx 400 #\input texinfo ‘s into a text file. Pasted the contents (all one line, no line breaks) into your script as a string (replacing the existing ‘#\input texinfo’. Changed the folder permissions for the two lib folders to read/write (temporarily).ran your script. It fixed all but a half dozen of the files. Went into the folders manually. The unchanged files stood out cause they didn’t have today’s date of modification. Manually pasted in the approx 400 from the original text file into those few.
Successfully uploaded to app connect where my app is now in Beta on test flight.
Thank You very much!
@stepper That's interesting, though I've found a better solution recently: You can add something like
#import pythonistaas the first line, and it'll be recognized as Objective-C source code (which isn't directly executable, so it doesn't cause issues with code signing).
Any chance we will see an updated template that uses all the great new features in version 3?
@RomSpy Yes, that's something I'd really like to do soon, and I've already done some of the work required, but it's still kind of a mess.
Is there an up-to-date summary of the idea for packaging up a Pythonista project to make an app? I see that the template linked from
doesn't exist anymore, and I'm not sure where to begin learning.
@sreyemnayr I tried your re-worked script and it worked well.
#import pythonista\nrather than
To make it run faster I prepend 10 strings in each iteration, e.g.
f.write("#import pythonista\n" * 10 + source)and set counter to increment by 10.
Here is a reworked script that adds the comments at the top but preservers coding= comments.
It is not perfect, but it helped me succesfully submit an app to the Appstore, I hope it is of help to every one.
#import pythonista # Change the ********** to point to the directory containing the Pythonista framework : project_path = '**********/PythonistaAppTemplate' pylib_path1 = '%s/PythonistaKit.framework/pylib' % project_path pylib_path2 = '%s/PythonistaKit.framework/pylib_ext' % project_path MAX_REPEATS = 10 import shutil import os import subprocess def check_is_executable(file_path): file_output = subprocess.check_output(['file', file_path]) if 'executable' in file_output: return True, file_output return False, file_output def fix_executable(file_path, dry_run=False): with open(file_path, 'r') as f: source = f.readlines() if 'coding:' in source.lower(): firstline = source start = 1 else: firstline = '' start = 0 if dry_run: if firstline: print(firstline) else: with open(file_path, 'w') as f: f.write(firstline + '#import pythonista\n' * MAX_REPEATS + ''.join(source[start:])) is_executable, out = check_is_executable(file_path) return not is_executable def fix_pylib(pylib_path, dry_run=False): print ("fixing", pylib_path) for path, dirs, files in os.walk(pylib_path): print(path, dirs, files) for filename in files: full_path = full_path = os.path.join(path, filename) is_executable, file_output = check_is_executable(full_path) if is_executable: extension = os.path.splitext(full_path).lower() if extension in ['.py', '.pym'] or filename == 'command_template': if dry_run: print '### Executable found: %s' % (filename,) fixed = fix_executable(full_path, dry_run) else: print 'Fixing %s...' % (filename,) fixed = False counter = 0 while not fixed: fixed = fix_executable(full_path) counter += MAX_REPEATS print 'Fixed with '+str(counter)+' dummy lines.' else: print '### Executable found, but does not seem to be Python code: %s' % (full_path,) if __name__ == '__main__': fix_pylib(pylib_path1, False) fix_pylib(pylib_path2, False)
so, this may be a stupid question, but my understanding of this problem is that
fileis running locally, and is getting rejected locally.
so, why not just edit /usr/share/file/magic (or copy it, edit it, then file -C to compile it to a new .mgc), or create an alias to file with a -m argument pointing to your custom magic file. It should be possible to edit the entry for pythonm or add custom search for the shebang or coding lines, to simply output a safe mimetype,
I think that is a very good question and a very interesting option to explore as it would avoid modifying the framework. I'll look into it as soon as I get a chance and report my findings back.
