Re: [libmicrohttpd] SEGFAULT after upgrading from 0.9.77 to 1.0.1

[Markus Doppelbauer]

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.:

    struct MHD_Response *response = MHD_create_response_from_callback( MHD_SIZE_UNKNOWN, 32*1024, content_reader_callback, userdata, NULL );

    MHD_add_response_header( response, header.name, header.value );

    statuscode = MHD_queue_response( connection, 200, response );

    MHD_destroy_response( response );

Problem fixed! \o/

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.

Thanks a lot guys!

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,

Well, we didn't try to break anything with the update, so you shouldn't
have to change anything on your side either. Can you send us a stack
trace/valgrind output and/or test code to reproduce? That'll expedite a
fix...

Happy hacking!
