bug#31457: 27.0.50; Move starttls.el and tls.el to lisp/obsolete/


From: Noam Postavsky
Subject: bug#31457: 27.0.50; Move starttls.el and tls.el to lisp/obsolete/
Date: Mon, 14 May 2018 20:03:12 -0400

Tags: patch
Severity: minor

Use of an external program such as gnutls-cli instead of the builtin
libgnutls based functions is already de-facto obsolete: see bugs 15905,
23759, 27658, and 31339.

Subject: [PATCH v1] Move tls.el and starttls.el to lisp/obsolete/

* lisp/obsolete/tls.el: Moved from lisp/net/tls.el.
* lisp/gnus/nnimap.el:
* lisp/url/url-http.el: Don't require tls, since it's obsolete.
* lisp/net/network-stream.el: Only require tls if we actually try to
use it (i.e., when (gnutls-available-p) returns nil).  Declare some
functions to fix compilation warnings.

* lisp/obsolete/starttls.el: Moved from lisp/net/starttls.el.
* lisp/net/sieve-manage.el:
* lisp/net/network-stream.el: Don't require `starttls' at the
top-level, declare the variables and functions used instead.
(network-stream-open-starttls): Only require `starttls' if
needed (i.e., gnutls-available-p fails).

* etc/NEWS: Announce obsoletion.
