Pygpsclient crashes when "save configuration" on macos about pygpsclient

[semuadmin]

Hi @jxl77,

Sorry you're having difficulties. The 'Save Configuration' facility has been tested on a variety of Apple MacOS devices - both Intel and Apple Silicon - and I've not come across this issue before. I'm unable to reproduce the error on my own 2021 Macbook Pro (Apple M1 Max) running MacOS Sonama 14.2.1 and using versions of Python from 3.8 to 3.12.

When you say PyGPSClient 'crashes', is there a Python error traceback available at the terminal? Unfortunately the detailed configuration data doesn't really help me much.

Are you able to use any other function which involves a “write to disk” operation e.g. data logging or GPX track recording? If not, it may be a local Python write permissions issue.

Are you running PyGPSClient in a virtual environment or VM?

Where are you trying to save the configuration to?

Other than this error, does PyGPSClient run normally?

I note you're running MacOS 12 (Monterey) - do I take it your machine doesn't support later versions? I also note you're using one or two external monitors - does the issue still occur if you disconnect those monitors and just use the Macbook's native screen?

Thanks for this rapid answer. I am running PyGPSClient   using the PyGPSClient  command line in a terminal. I have closed all applications, rebooted the computer,  suppress the external monitor, started again, but with the same result  : I   connect to the gps through USB/serial, at  115200 bds,  properly receive the flux, then go to file/save configuration, and it crashes. All the other items seem to work properly. I have changed the baud rate of the gps using the UBX commands and it was properly changed in the GPS. try several other items, Only the save/configuration has a problem, either by the menu or by the icon in the UBX panel. I am using Monterey because  I dont rush  to new systems because of uncertainty of behaviour of  many applications I use. I prefer a conservative approach, than spending my time in upgrades. Thanks for any help Jacques

Your OS error report includes:

Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000

This indicates an attempt to access unmapped memory. This may indicate a corrupt Python installation on your platform, though I'm at a loss to explain why this would only manifest itself during a Python write() operation.

1. How did you install Python 3.10 on your platform? Was it from the official Python.org download?
2. Could you try running the following code snippet and let me know the response:

import tkinter
tcl = tkinter.Tcl()
print(f'tkinter version is {tcl.call("info", "patchlevel")}')

You should see something like this:

tkinter version is 8.6.13

If the reported tkinter version is less than 8.6.n, you'll need to reinstall Python from the official Python.org repository. PyGPSClient is only compatible with tkinter >= 8.6.

3. You could also try running the following code snippet to establish if there is a general issue with Python file write permissions:

import os

fname = "testfile.txt"
with open(fname, "w", encoding="utf-8") as outfile:
    print(f"file {fname} created OK")
    outfile.write("this is a test")
    print(f"file {fname} written OK")
os.remove(fname)
print(f"file {fname} deleted OK")

Hi @jxl77 Are you able to provide any further diagnostics on this, as per previous response?

[jxl77]

Thanks for your concern.

Since my first trys, I have decided to upgrade my system to the latest Somona.
I have also cleaned my python installation (there were 4 versions installed by different manners)
Pygpsclient is now working properly.

The bad thing is that I can no longer reproduce the bug which could have originated from various sources.

Thanks for your efforts.

OK glad it's sorted. Are you happy to close the issue now?

[jxl77]

yes, we can close it
