When a TLS server shuts down the connection to Emacs (for instance, when
timing out a https connection), Emacs gives this ominous warning:
gnutls.c: [0] (Emacs) fatal error: The TLS connection was non-properly terminated.
Normal network connections don't give any warnings, so TLS connections
shouldn't, either.
In GNU Emacs 24.3.50.5 (x86_64-unknown-linux-gnu, GTK+ Version 3.8.2)

I added this:
#ifdef HAVE_GNUTLS3
/* Function to log a simple audit message. */
static void
gnutls_audit_log_function (gnutls_session_t session, const char* string)
{
if (global_gnutls_log_level >= 1)
{
message ("gnutls.c: [audit] %s", string);
}
}
#endif
...
#ifdef HAVE_GNUTLS3
fn_gnutls_global_set_audit_log_function (gnutls_audit_log_function);
#endif
...so if this is an auditing message, you should see the "[audit]"
prefix. Since you don't, either you're on GnuTLS 2.x (unlikely) or
GnuTLS is saying it's a very high priority message that shouldn't be
filtered out. I could add special handling for this specific message
but is that the right thing to do?

Let's see:
[larsi@building src]$ ldd emacs | grep tls
libgnutls.so.28 => /lib64/libgnutls.so.28 (0x0000003f64e00000)
That's gnutls 2.8, I guess? This is on a laptop running Fedora 19.

No, it should be gnutls 3.x, probably 3.0.x. 28 = 32 - 4 is the API
version.

Speaking of irrelevant messages. I just got this:
gnutls.c: [0] (Emacs) fatal error: An unexpected TLS handshake packet was received.
gnutls.el: (err=[-19] An unexpected TLS handshake packet was received.) boot: (:priority NORMAL :hostname i.chzbgr.com :loglevel 0 :min-prime-bits 256 :trustfiles (/etc/pki/tls/certs/ca-bundle.crt) :crlfiles nil :keylist nil :verify-flags nil :verify-error nil :callbacks nil)
Errors like this are to be expected (the server just closes the
connection for some reason or other). The URL library should deal with
this without bothering the user with these warnings...

The URL library can't trap these. GnuTLS considers them highest
priority, so blocking them out would block most useful log information.
I'm not sure what to do without breaking things or complicating the
configuration significantly.

I'm not sure, but my earlier comment stands :)

Useful to whom? It's probably useful when developing applications that
talk TLS, but it's not useful to the user who's just trying to read a
web page.
If you're reading a page, and you're loading a picture that fails, Emacs
should display a "failed download" image, not spew TLS-level errors to
the user. The user isn't interested.
So I think that, basically, no TLS errors should be displayed to the
user. At least I haven't seen one yet that's been useful to me as a
user.

OK. I will log them to a special " *TLS errors*" buffer. That's a good
balance.
Doing that from C is not obvious, compared to the standard `message'
function. Any hints? Should I just call `Fget-buffer-create' and
call functions to append to the returned buffer Lisp_Object, or is there
a magical equivalent?
Also, I think we should add that buffer, plus the version of GnuTLS and
the priority string, to bug reports. WDYT?
Thanks
Ted

Yeah, that would be good. And perhaps limit the size of the buffer.

I just had a look at message_dolog (which puts data into the *Messages*
buffer). It didn't look pretty... Is all that really necessary?

For all Emacs bug reports? Hm...

It rarely gets annoyingly big, but OK... 50K messages?

Not for my usage, definitely. I can call the usual ELisp functions, I
just want to know if there's a convenient C shortcut.

Yes, if GnuTLS is enabled. We already sent the messages (from
*Messages*) and the default is not very verbose.

I've now moved the fatal GnuTLS errors to level 1, so nothing is
messaged by default.
