It's just so useful being able to retrieve the current env block from
our services. Add a concept for that. It's really simple, and dumb.
In many ways it's like /proc/$PID/environ, but shows the actual
environ[] array visible to the app, not just some memory that was
originally used for the env block passed in, but might have been rearranged.
Let's give the user control on how to handle JSON "null" assignments of
the log level. As one of three cases: as failure, as LOG_NULL (i.e. to
turn off logging) or as LOG_INFO (as our usual default log level).
Let's then use that in the generic SetLogLevel() call, so that callers
can use it to explicitly turn off logging in a service.
Note that this was (probably accidentally) already implemented, except
that the introspection enforcement blocked it. Let's clean this up and
make this officially a thing, since it's generally useful to turn off
logging I think.
This also makes
- make many loggers refactored,
- log_event_error() and friends UdevEvent object,
- introduces log_event_trace().
No functional change, just refactoring and preparation for later
commits.
