I'm on Emacs master, but this behavior has been evident for quite some
time, a year or two I think.
I often have trouble reconnecting Gnus' nntp servers after sleeping the
laptop in one location, and waking it up in another, connecting to a new
wifi network (I'm using Arch linux, if it matters).
I edebugged `nntp-open-connection', and realized that the error (which
is getting handled by `nnheader-report', that's why I didn't notice it)
is actually a dns error:
(error "news.gmane.io/nntp Temporary failure in name resol...")
Other Emacs network connections behave as normal. But this error for
this particular server persists until I restart Emacs.
Are DNS lookups cached? Cached per connection? Is there anything we can
do to flush whatever's "stuck"?
Here's the code that opens the connection; in my case it's
nntp-open-network-stream/network.
Happy to help with further debugging!
(let ((coding-system-for-read 'binary)
(coding-system-for-write 'binary)
(map '((nntp-open-network-stream network)
(network-only plain) ; compat
(nntp-open-plain-stream plain)
(nntp-open-ssl-stream tls)
(nntp-open-tls-stream tls))))
(if (assoc nntp-open-connection-function map)
(open-network-stream
"nntpd" pbuffer nntp-address nntp-port-number
:type (cadr (assoc nntp-open-connection-function map))
:end-of-command "^\\([2345]\\|[.]\\).*\n"
:capability-command "HELP\r\n"
:success "^3"
:starttls-function
(lambda (capabilities)
(if (not (string-match "STARTTLS" capabilities))
nil
"STARTTLS\r\n")))
(funcall nntp-open-connection-function pbuffer)))
