Dear maintainers,
Iʼm not sure whether that a bugreport or a support request, I hope you will
excuse me for opting for the former.
Basically, I have an instance of Emacs 27 — rev. aea1b4db72 — a head of
emacs-27 from about two weeks ago, which, have been running for that time, is
failing to resolve any remote hostname synchronously (which, for instance, Gnus
normally does), while asynchronous requests (as in ‘url-retrieve’) are still
working fine.
A newly started instance of the same Emacs does not demonstrate the issue. And
alas, despite being almost convinced, that I had already met this problem
before, I cannot say how exactly to reproduce it.
However, I suppose, the fact, that this is by no means a pristine configuration
is not much relevant, since the error goes down to C sources, namely to
‘make-network-process’:
(make-network-process :name " *net-test*"
:buffer (get-buffer-create "
*net-test*")
:host "gnu.org" :service 80
:nowait nil)
;; Debugger entered--Lisp error: (error "gnu.org/80 Name or service not
known")
More specifically, a call to getaddrinfo() in ‘network_lookup_address_info_1’
returns EAI_NONAME.
Could it be a problem in GNU Emacs, or have I broken my system somehow?
