The logging categories are registered by the applications, like
osmo-nitb, during startup. Thus, the VTY have to provide the logging
commands according to the logging categories that the application
has registered.
Before this patch, the VTY contained the logging categories
hardcoded. Thus, any change in the logging categories by the
application would not be shown by the VTY.
So far, this was not a problem because all applications used the
same logging categories. However, according to what Harald told
me, this may be a problem in the future.
This patch resolve the lack of integration between the logging
framework and the VTY by generating the VTY logging commands
from the logging categories registered.
Since this patch changes one function of the libosmocore API,
it follows another patch for the openbsc application to get in
sync with the new function layout.
I have reworked and renamed the functions:
* log_vty_category_string()
* log_vty_level_string()
to provide the new ones that generate the exact output that VTY
requires.
This patch does not release the memory allocated by
talloc_zero_size() to store the VTY strings for the commands
and the description. I found no exit function that can clean
up resources that were allocated.
Before this patch, there was a bug in the code caused by a memcpy
from one data structure to another. unfortuantely the data structures
were not the same, so we have to explicitly iterate over the array
and assign the structure members manually.
