Thanks for your help in testing this - there's no way I could have found it otherwise. I think version 1.8.0 is good enough for now - you won't see what the problematic logging message actually is until the next release.

That's very odd, and I'm not able to reproduce it on my OpenSUSE system (Python 3.4.6).
What does camera.wait_for_event(1000, context) return when you're not using Python logging?
Does it also happen if you use gp.gp_camera_wait_for_event(camera, 1000, context) instead of camera.wait_for_event(1000, context)?
Can you try it with version 1.7.0 of python-gphoto2?

Yep!

When I try to debug it using ipdb, I get stuck in a loop in port_log.py:

Yep, it still happens on gphoto2==1.7.0.
I just tried on a Raspberry Pi running the latest Raspbian and it does the same. My camera is a Canon EOS 7D if that matters.

However, it does work on Python 2.7!

OK, I'm guessing that attempting to log a message to Python is generating a fault that then gets logged to Python...
Python 3.5 is different from Python 3.4, which was causing problems with SWIG's -builtin option. Can you try installing 1.7.1 with an environment variable PYTHON_GPHOTO2_NO_BUILTIN=1.

I've set up a clean Ubuntu 16.04 installation on a virtual machine and am not getting the problem with my Canon EOS 100D. Will try some other cameras.
PS Have tried it with my Canon A1100 IS and it's still fine. Enabling Python logging shows some debug output on each wait_for_event call though.

jim-easterbrook
commented on July 3, 2024
I strongly suspect this is camera dependent. Possibly the driver for your camera is logging with unexpected parameters which the conversion to Python mishandles, but that wouldn't explain why it works with Python 2.7.
Can you try it again on 2.7 but with a logging.basicConfig() call (after importing logging) so we actually get some log output.
from python-gphoto2.
jim-easterbrook
commented on July 3, 2024
I've been puzzling over this, trying to come up with a theory to explain what's happening. One possibility is that camera.init() (known to leak memory!) is trashing the Python wrapper's record of what Python function to call when a message is to be logged. camera.init() is successfully logging some messages though, so any corruption happens towards the end of its call.
Can you try calling gp.gp_log_remove_func(1) (where 1 is the value returned by gp.use_python_logging()) before calling camera.wait_for_event()?

Hopefully this will shed some light.. I added a print() to the code on line 160 of site-packages/gphoto2/port_log.py as such:
def callback(self, level, domain, msg):
print("\nNew log message:\n%s" % msg)
self.log(self.mapping[level], '(%s) %s', domain, msg)Which creates this rather long output:

It's no wonder I thought that I was getting stuck in a loop!
Running gp.gp_log_remove_func(1) does stop the segfault from appearing.

commented on July 3, 2024
Yes, the lowest level logging is very verbose. I half expected calling gp.gp_log_remove_func(1) itself to segfault. As it didn't I think I can assume that the data I was talking about is intact.
Can you try modifying your print statement:
def callback(self, level, domain, msg):
if level != 3:
print("\nNew log message", level, domain, "\n", msg)
self.log(self.mapping[level], '(%s) %s', domain, msg)

However, the last log message is basically the same, and there's nothing about it that would seem likely to upset the logging system. I suspect the problem is happening before the Python callback function you edited is called.
If you download python-gphoto2 from PyPI (https://pypi.python.org/pypi/gphoto2/1.7.1) you could edit the SWIG generated wrapper before installing, which might yield some useful information. The file you want to edit is src/swig-bi-py3-gp2.5.0/port_log_wrap.c (we'll go back to the -builtin version now). Find the gp_log_call_python function and add a printf statement:
if (Py_IsInitialized()) {
printf("log: %d %s %s\n", level, domain, str);
PyGILState_STATE gstate = PyGILState_Ensure();
I hope you'll be able to install as follows:
python3 setup.py build
sudo python3 setup.py install
Don't bother posting all the output, just the last bit before the segfault.

jim-easterbrook
commented on July 3, 2024
I've found one remotely possible cause of your segfault problem, and it's camera dependent. To call the Python logging function from C I use Py_BuildValue to assemble the parameters (level, domain & str) into a Python object. The documentation of Py_BuildValue says it can fail (e.g. if it runs out of memory) and I'm not currently checking for this. If the driver for your camera generates extremely verbose debug information this might be a problem.

Ulrika! (Sorry, was watching W1A last night.)
It appears that either the domain or str callback parameter (probably the latter) contains a non-ASCII character, and the error this causes is now being handled better. This also explains why it worked with Python 2 - all strings are byte rather than Unicode.
As there's no way of knowing what character set any particular camera uses I guess it would be safer (in Python 3) to pass bytes values instead of str and leave it to the Python callback to decide what to do.
