Having the "global conf" settings intermixed with the
backend sections
caused a number of issues when we first started working on
this. That's
part of why we require the "self.configuration" usage all
over in the
drivers. Each driver instantiation is it's own independent
entity.
Yes, each driver instantiation is independent, but that would
still be
the case if these settings inherited values set in [DEFAULT]
when they
aren't set in the backend section.
Agreed. If I explicitly set something in the [DEFAULT] section,
that should
carry through and apply to all the backends unless overridden in
the
backend-specific section.
Bottom line "yes", ideally in the case of drivers we would check
global/default
setting, and then override it if something was provided in the driver
specific
setting, or if the driver itself set a different default. That seems
like the
right way to be doing it anyway. I've looked at that a bit this
morning, the
issue is that currently we don't even pass any of those higher level
conf
settings in to the drivers init methods anywhere. Need to figure out
how to
change that, then it should be a relatively simple fix.
Actually, I think it should be slightly different. If I set a variable in
the global/default section of the config file, then that should override any
defaults in the code for a driver.
Hmm... well, on the bright side that might be easier to implement at least :). I
guess I don't agree on the meaning of "DEFAULT", to me a "DEFAULT" section
means, "these are the defaults if you don't specify something else", no? Your
proposal seems really counter-intuitive to me.
That's what I proposed.
If you specify anything in the driver-specific portion of the config file, that
takes priority over everything. If you specify something in the DEFAULT portion
of the config file, then that takes priority over the in-code defaults. If you
specify a default value in the driver-specific code, that takes priority over
any defaults specified in the global/generic code.
