gnutls-error

gnutls-error

[Peter Münster]

Hi,

With the latest bzr-version (revno 116751), `url-retrieve-synchronously'
terminates with a gnutls-error.

After this command:
(url-retrieve-synchronously "https://btc-e.com/api/2/btc_eur/ticker")

I get this output:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (gnutls-error #<process btc-e.com> -19)
  signal(gnutls-error (#<process btc-e.com> -19))

Hi Peter,

I can't duplicate the error.  Could I ask you to do `M-x
report-emacs-bug' and include the output of `gnutls-cli -v' and
`gnutls-cli https://btc-e.com/api/2/btc_eur/ticker'?  It would be very
helpful to direct bugs there instead of emacs-devel or gnu.emacs.help.

This specific host seems inaccessible to me, but maybe it's a transient
error.

Thanks
Ted

Hi Ted,

Done.

I guess, that this should be "gnutls-cli btc-e.com"?

Before reporting a bug, I wanted to be sure, that I wasn't missing
something obvious (missing library or something).
All right, next time I use report-emacs-bug as the first step.

Probably. Firefox can get the page here.

Thanks for your efforts,

Right, sorry.  I was at work (a perpetual state, lately) and in a
hurry.  I meant that, plus
`curl -v https://btc-e.com/api/2/btc_eur/ticker' which (with OpenSSL)
can be a nice support statement of the problem, especially if it's a
GnuTLS-only problem.

I'll continue in the bug thread, but wanted to let you know I appreciate
your effort and will try to get this resolved.

Thanks for your patience
Ted
