[GNUnet-SVN] [gnurl] 35/150: http2: set DEBUG_HTTP2 to enable more HTTP/2 logging

[gnunet]

This is an automated email from the git hooks/post-receive script.

ng0 pushed a commit to branch master
in repository gnurl.

commit 0630bb21be5bf5ff4300229ea7c0f2d626ddcb98
Author: Daniel Stenberg <address@hidden>
AuthorDate: Tue Jan 30 23:19:53 2018 +0100

    http2: set DEBUG_HTTP2 to enable more HTTP/2 logging
    
    ... instead of doing it unconditionally in debug builds. It cluttered up
    the output a little too much.
