Nana provides improved support for assertion checking and logging in C, C++
|
|
using GDB. In particular it provides:
|
|
|
|
o Operations can be implemented directly in C or by generating
|
|
debugger commands which do the checking and logging only if the
|
|
application is run under the debugger. The debugger based calls
|
|
require are very space efficient (0 or 1 bytes per call).
|
|
o Support for checking real time constraints.
|
|
o Support for assertion (invariant checking) including:
|
|
+ Space and time efficient (at least versus <assert.h>)
|
|
For example: assert(i>=0) uses 53 bytes on a i386 vs
|
|
an optimised nana call which uses 10 bytes per call.
|
|
+ Checking can be turned on or off at compile or run time.
|
|
+ The action taken when an error is detected can be modified
|
|
on a global and per/call basis.
|
|
o Support for logging (printf style debugging) including:
|
|
+ Logging can be turned on and off at compile or run time.
|
|
+ Logging to files, processes or circular buffers in memory
|
|
with optional time stamping.
|
|
o Support for the quantifiers of predicate calculus (forall, exists).
|
|
o Support for before and after state saving and checking (x, x').
