Quite some code which was hold back in favor of the config and plugin stuff implements: * mmapcache: mru cache for unused memory mappings * mmap: single mmaped areas * mmapings: manages mmaps established for one filedescriptor

NoBug debugging flags hierachy
|
|
==============================
|
|
|
|
NoBug logging is controlled by flags which can be configured with the
|
|
NOBUG_LOG environment variable. This flags can be hierachically
|
|
organized.
|
|
|
|
The documentation about this hierachy is maintained here:
|
|
|
|
(PLANNED, not all are implemented yet)
|
|
|
|
all # global logging
|
|
lumiera # standard
|
|
library # all support library
|
|
plugin # plugin loader
|
|
backend # all backend
|
|
file_all # filehandling subsystem
|
|
file # file access
|
|
filedescriptor # internal filedescriptors
|
|
filehandle # posix filehandles
|
|
filehandlecache # mrucache for filehandles
|
|
mmap_all # file mapping subsystem
|
|
mmap # mmap objects
|
|
mmapings # mmap range containers
|
|
mmapcache # mmap range containers
|
|
cache_all # caching subsystem
|
|
scheduler_all # all scheduler
|
|
threads # threadpool management
|
|
tasks # work requests
|
|

|
|
idle # low priority queue
|
|
proc # all proc
|
|

|
|

|

Explanation
|
|
-----------
|
|
|
|
We have 2 main log flag hierachies, 'all' and 'event'.
|
|
* 'all' reflects the application progress and will be used for
|
|
debugging the application by the programmers. This is exposed in 2
|
|
subgroups: 'lumiera' which is used for normal application logging
|
|
and, 'detail' which contains logging which might be time critical,
|
|
expensive or of very high volume.
|
|
* 'event' logs user actions like GUI clicking, menu selections giving
|
|
an idea how a bug was triggered.
|
|
|
|
Later on this main hierachies will run in different ringbuffers.
