>From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: "F. Jason Park" Date: Mon, 16 Aug 2021 04:38:18 -0700 Subject: [PATCH 19/29] Standardize auth-source queries in ERC * lisp/erc/erc.el (erc-password): deprecate variable only used by `erc-select-read-args'. Server passwords are primarily used as surrogates for other forms of authentication. Such use is common but nonstandard and often discouraged in favor of the de facto standard, SASL. Fans of invoking `erc(-tls)' interactively should be coerced into using auth-source instead. (erc-select-read-args): Before this change, `erc-select-read-args' offered to use the value of a non-nil `erc-password' as the :password argument for `erc' and `erc-tls', referring to it as the "default" password. And when `erc-prompt-for-password' was nil and `erc-password' wasn't, the latter was passed along unconditionally. This only further complicated an already confusing situation for new users, who in most cases shouldn't be worried about sending a PASS command at all. Until SASL arrives, they should provide server passwords manually or learn to use auth-source. (erc--auth-source-determine-params): New helper for `erc--auth-source-search' with potential for wider role as default value of custom function. Favors :host and :port fields above others. Prioritizes session IDs over announced servers and dialed endpoints. (erc--auth-source-search): New function for consulting auth-source and sorting result as per default params provided by above functions. (erc-server-join-channel): Use helper for consulting auth-source facility. Also accept nil for first argument (instead of server). In this case, allow default params option above to determine best course of action. (erc-cmd-JOIN): use above-mentioned facilities when joining new channel. Omit server when calling `erc-server-join-channel'. Don't filter target buffers twice. Don't call `switch-to-buffer', which would create phantom buffers with names like target/server that were never used. IOW, only switch to existing target buffers. (erc-open, erc-determine-parameters, erc-compute-password): Move password figuring from former to latter, and from there to `erc-compute-password', which is a new function that figures out how to call `auth-source-search' based on the value of the new option `erc-connect-auth-source-host'. (erc-connect-auth-source-host): Add new option for customizing the :host param passed to `auth-source-search' while looking up the initial PASS arg. The default setting preserves existing behavior of matching against the dialed host name or IP address stored in `erc-session-server'. Other options allow skipping auth-source lookup altogether or favoring network ID, when non-nil. * lisp/erc/erc-services.el (erc-nickserv-get-password): pass network ID, i.e., effective session ID, when looking up password in `erc-nickserv-passwords' and when formatting prompt for user input. (erc-nickserv-passwords): add comment to custom option definition type tag. * test/lisp/erc/erc-services-tests.el: add new test file for above changes. For now, also store auth-source-related tests belonging in erc-tests.el here. * lisp/erc/erc-join.el (erc-autojoin--join): Don't pass session-like entity from `erc-autojoin-alist' match to `erc-server-join-channel'. Allow that function to decide for itself which host to look up if necessary. * lisp/erc/erc-compat.el (erc-compat--auth-source-pass--couch, erc-compat--auth-source-pass--find-match, erc-compat--auth-source-pass--build-result, erc-compat--auth-source-pass-search, erc-compat--auth-source-pass-backend-parse): Add some adapters to make auth-source-pass behave more like netrc in ways ERC relies on. --- lisp/erc/erc-compat.el | 86 +++++++ lisp/erc/erc-join.el | 2 +- lisp/erc/erc-services.el | 40 ++-- lisp/erc/erc.el | 174 ++++++++++---- test/lisp/erc/erc-services-tests.el | 358 ++++++++++++++++++++++++++++ 5 files changed, 588 insertions(+), 72 deletions(-) create mode 100644 test/lisp/erc/erc-services-tests.el diff --git a/lisp/erc/erc-compat.el b/lisp/erc/erc-compat.el index 16cfb15a5a..a833a61456 100644 --- a/lisp/erc/erc-compat.el +++ b/lisp/erc/erc-compat.el @@ -150,6 +150,92 @@ erc-subseq (setq i (1+ i) start (1+ start))) res)))))) +;;;; Auth Source + +;; We want a unified interface to auth-source, but that depends on +;; upstream providing a consistent experience.
