Can you share a larger piece of code or give more details, like used mode (internal polling or external polling), polling function, other relevant information?

What was your issue? How did you fix it?

I am getting "Assertion failed" from "connection.c:6864":
   case MHD_CONNECTION_CHUNKED_BODY_UNREADY:
     mhd_assert (0);

This happens if I create a response from callback, e.g.:


     MHD_add_response_header( response, header.name, header.value );
     statuscode = MHD_queue_response( connection, 200, response );
     MHD_destroy_response( response );

Problem fixed! \o/



Thanks a lot guys!

I have a couple of test cases that call some MHD functions internally, but after creating fake MHD_Connections to pass to the functions instead of NULL the problem was fixed. On Mon, Feb 26, 2024 at 5:41 PM silvioprog <silviop...@gmail.com <mailto:silviop...@gmail.com>> wrote:

Seems like it will be hard to figure out the problem. I mean, since the application is crashing, I can understand what is happening. The only error message I could catch was this one in the attached picture.

I'll to try to fix the problem or at least reproduce it.

Hey Christian. =)

Yes sure, I'll try to reproduce the problem and provide all the logs.

Hi Silvio,


have to change anything on your side either. Can you send us a stack

fix...

Happy hacking!

Well, we didn't try to break anything with the update, so you shouldn't trace/valgrind output and/or test code to reproduce? That'll expedite a
