Wireshark-dev: Re: [Wireshark-dev] [Wireshark-commits] rev 28900: /trunk/epan/dissectors/ /trun
Hi,
Generally speaking, I think that assertions in cases when local (static) function
is invoked with wrong parameters are legal. The caller function must take care
about parameters (and it does currently in packet-pw-atm.c).
For global functions some other approach should be used, of course.
Specifically, I consider replacing assert(payload_size >= 0) with DISSECTOR_ASSERT as acceptable.
But I do not like removal of NULL pointer check. I believe that aboring application
internally (via abort()) is always better than aborting via exception in the OS kernel.
Removing second assert() also removes important information:
"this function REQUIRES to be invoked with valid pointer as a parameter".
Regards,
Artem Tamazov

Log:
Replace one assert() with DISSECTOR_ASSET(), so we don't crash, and get
rid of another, as the pointer in question is non-null in all calls (if
somebody adds another call with a null pointer, it'll crash when
dereferencing the pointer in any case).
