[gst-devel] question re: debugging

[Thomas Vander Stichele]

Hi,

have some simple questions re: debugging; I'm trying to update the
manual to document the new system.

a) Should the mapping explicitly be: one feature -> one or more
categories ? Or can I use one category for a complete plug-in (say, all
of the oss elements) I'm asking because I think that if each element
would have it's own category, the output of --gst-debug-help is going to
be pretty long.

b) In the case where one category can be used for multiple elements,
what's the best way to register categories ? Ie, where is the define,
where the DEBUG_CATEGORY_INIT, and where the registering call ?

c) Going through the code, it looks to me like having multiple _INIT
calls with the same name would result in different entries.  Should I
try to add code that makes sure a category name is registered only once
? How does code in a second element registering the same category name
"know" what variable to pass to the debugging system ?

c) Why are the core's debug categories in capitals, and the plugin's
debug categories not ? Should external libs/programs use capitals or not
?

Once I figured it out a little and added code to handle oss (so I can
debug my actual problem atm :)) I can add it to the manual and remove
the old stuff.

Thanks
Thomas
