Error with mimetype on OS-X 11 (Big Sur)
by Chris Barker Jan. 8, 2022

Jan. 8, 2022

I've just got a new mac with OS-X 11.6 (still Intel). But when I try to run a PyInstaller built application, I get this error: No document available for {'mime': 'application/x-maproom-project-zip', 'loader': <maproom.loaders.project.ZipProjectLoader object at 0x7f9669ce6e10>, 'uri': 'template://default_project.maproom'} And the app won't start. This has worked just fine on numerous previous OS-X versions. I have the source code, but the developer that built it is no longer with us, so it'll take b e a bit to get up to speed, and I don't even know where to start! Is this a PyInstaller issue? or a code issue, or ??? Hints: The application is called MapRoom (maproom) it works with "projects" that are essentially a zip file with all the info required in it. I think, on startup, it loads a empty default project, presumably "default_project.maproom" So I think that's where the app startup code is barfing, not having the mime type registered properly. But where / how am I supposed to do that? or maybe it's not a mime type registration issue, but simply that the template can't be found -- so a path issue in the App bundle?? Anyway, I'll be digging into this deeper in the source code, but if anyone has seen anything like this, any hints would be appreciated!

py2app fails to build PyQt5 apps anymore
by Barry Scott Jan. 2, 2022

Jan. 2, 2022

For a long time I have been happily building my App bundles using py2app. At some point that stopped working. I do not have a record of exactly when. Last time I saw everything work was Feb 2021. I have reduced the problem to a simple test program and scripts to build and run the test code to show the issue. As a comparison I have py2app and pyinstaller versions of the tests. The pyinstaller version works and the py2app version fails. The code is on github here: https://github.com/barry-scott/scm-workbench/tree/master/Source/Experiments Run ./build-py2app.sh to build and run the py2app version. Run ./build-pyinstaller.sh to build and runt he pyinstaller version. The scripts: 1. build a venv 2. run gui_test.py from the command line 3. build the app using py2app or pyinstaller 4. run the app. I am using macOS 12.1 on Intel MacBook Pro (15-inch, 2016). Python 3.10.1 from python.org. The gui_test.py code logs to ~/gui_test.log at key points. Here is the source: ---- #!/usr/bin/env python import sys import os log_filename = '%s/gui_test.log' % (os.environ['HOME'],) sys.stdout = open( log_filename, 'a' ) sys.stderr = sys.stdout print('----

self.setMinimumSize( QSize(350, 100) ) self.setWindowTitle( 'GUI test - python %s' % (py_ver,) ) self.setCentralWidget( QLabel( ' GUI test - python %s ' % (py_ver,), self ) ) def main( argv ): print('QtWidgets.QApplication()', flush=True) app = QtWidgets.QApplication( argv ) print('HelloWindow()', flush=True) main_win = HelloWindow() print('main_win.show()', flush=True) main_win.show() print('app.exec_()', flush=True) rc = app.exec_() print('rc', rc, flush=True) return rc if __name__ == "__main__": sys.exit( main( sys.argv ) ) ---- On a successful run the log shows: ---- gui_test.py
