I've been having trouble migrating my OOT module to GR 3.10 (currently testing with \
3.10.5) due to the Python block logging levels not working as they did prior to 3.10. \
Currently, I have a parameter on most of my blocks to selectively set the log level \
per block instance to help filter what is printing, however, it doesn't seem this \
works anymore.
The way I have it implemented is in the __init__ function of my blocks I run:
self.logger = gr.logger(self.alias())
self.logger.set_level(log_level)
Then elsewhere in the class issue logging statements as usual: \
self.logger.debug(f'some debug message')
In GR 3.9, this would print "some debug message" if that block's log_level was set to \
debug. However, now in 3.10 it appears nothing is being printed to stdout at all, \
regardless of log level.
I'm aware there have been some changes in the logger in 3.10, but the OOT porting \
guide suggests the only that need to be made are with the C++ logger (and that the \
old logging API still works—for now).
Are there any changes that must be made to the Python logger too?
Thanks in advance!
Jason
