The tp_basicsize field, as well as a few others, seem to be inherited from whatever is set in tp_base. In absence of a tp_base, Python will set it to PyBaseObject_Type, which is not at all correct for Panda types.
The main motivation behind this change is to get rid of a
signed integer overflow that sometimes happens in the prime
multiplication step, which is (per the C++ spec) undefined
behavior. However, it's probably for the best to use only
unsigned int when the function is clearly trying to avoid
negative values.
Not that I suspect it matters much, but I have also heavily
tested that the behavior of the function is unchanged (at
least on PC hardware - signed integer overflow doesn't
behave portably) although it may now be slightly faster due
to the fact that I have removed the floating-point math.
While it becomes possible to do this now, it should not become standard practice, and we should deprecate cases where we already do it by renaming either the static method or the property.
Fixes#444
This changes includes so that local includes are consistently
#include "localFile.h"
while system and third-party includes are consistently
#include <systemFile.h>
This commit mostly converts the former to the latter; the two
exceptions are in android_main.cxx and fmodAudioSound.h, where
the reverse was necessary.
This is to fix eg. public ButtonHandle members from being returned as const reference, which means they won't outlive the struct they are accessed on, a recipe for obscure crashes.
The is_trivial() criterium for this to apply is admittedly really arbitrary; I haven't really figured out what the right criterium should be, but it's better than hardcoding ButtonHandle.
For example, this will let us pass a ConfigVariableFilename to anything that accepts a Filename, just like in C++.
Does not work if the return value if the typecast operator requires management.
Only the basics are supported; the __members__ or iter interface is not supported at this time.
