Hi folks, I just had a nasty issue with duplicate ett_* entries (well, one, actually). The issue was in dissector A but I was working on dissector B and had not run Wireshark after building with the changes in A, so it looked like the issue was in B. I notice that proto_register_subtree_array does not take any parameters indicating which dissector it is called from. Could we make that call a macro that passes the code line and function name as the last two parameters so the g_error printed out can tell us where the problem lies?
These issues are so rare, I would rather not complicate this routine. It would also have some overhead since every group of etts would have to be registered with the affected dissector.
In the end I used gdb to figure it out, but life would have been easier if the error message told me.
Use of a debugger seems an appropriate approach since you can easily obtain a backtrace from it, and print the address of the ett item to learn which dissector registered the ett. -- Kind regards, Peter Wu https://lekensteyn.nl ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
