bug#16543: 24.3; Newsticker retrieve method and https


From: Cédric Chépied
Subject: bug#16543: 24.3; Newsticker retrieve method and https
Date: Sat, 25 Jan 2014 01:20:22 +0100
User-agent: Wanderlust/2.15.9 (Almost Unreal) SEMI/1.14.6 (Maruoka) FLIM/1.14.9 (Gojō) APEL/10.8 Emacs/24.3 (x86_64-unknown-linux-gnu) MULE/6.0 (HANACHIRUSATO)

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':


When the newsticker-url-list starts with an https url, newsticker tries to use
tls for all other urls.

start emacs -Q
go to buffer scratch
type: 
(setq newsticker-url-list (quote ( ("Archlinux"
"https://www.archlinux.org/feeds/news/"; nil nil nil) ("Bonjour Madame"
"http://feeds2.feedburner.com/BonjourMadame"; nil nil nil) )))
M-x eval-buffer
M-x newsticker-treeview

It hangs and last messages are:
Newsticker started!
Contacting host: www.emacswiki.org:80
Opening TLS connection to `www.archlinux.org'...
Opening TLS connection with `gnutls-cli --insecure -p 443 www.archlinux.org'...
Opening TLS connection to `feeds2.feedburner.com'...
Opening TLS connection with `gnutls-cli --insecure -p 80 
feeds2.feedburner.com'...failed
Opening TLS connection with `gnutls-cli --insecure -p 80 feeds2.feedburner.com 
--protocols ssl3'...failed
Opening TLS connection with `openssl s_client -connect feeds2.feedburner.com:80 
-no_ssl2 -ign_eof'...done


I found a "workaround":
start emacs -Q
go to buffer scratch
type: 
(setq newsticker-url-list (quote ( ("Bonjour Madame"
"http://feeds2.feedburner.com/BonjourMadame"; nil nil nil) ("Archlinux"
"https://www.archlinux.org/feeds/news/"; nil nil nil) )))
M-x eval-buffer
M-x newsticker-treeview

It works and I can say "Bonjour madame" (not really with emacs -Q because
pictures are not displayed). It only hang when https url is the first one. I did
not try with several https url.



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.3/etc/DEBUG.
