* lisp/erc/erc-backend.el (erc-server-connected): Revise doc string. (erc-server-reconnect, erc-server-JOIN): Reuse original ID param from the first connection when calling `erc-open'. (erc-server-NICK): Apply same name generation process used by `erc-open'; except here, do so for the purpose of "re-nicking". Update network identifier and maybe buffer names after a user's own nick changes. * lisp/erc/erc-networks.el (erc-networks--id, erc-networks--id-fixed, erc-networks--id-qualifying): Define new set of structs to contain all info relevant to specifying a unique identifier for a network context. Add a new variable `erc-networks--id' to store a local reference to a `erc-networks--id' object, shared among all buffers in a logical session. (erc-networks--id-given, erc-networks--id-create, erc-networks--id-on-connect, erc-networks--id--equal-p, erc-networks--id-qualifying-init-parts, erc-networks--id-qualifying-init-symbol, erc-networks--id-qualifying-grow-id, erc-networks--id-qualifying-reset-id, erc-networks--id-qualifying-prefix-length, erc-networks--id-qualifying-update, erc-networks--id-reload, erc-networks--id-ensure-comparable, erc-networks--id-sort-buffers): Add new functions to support management of `erc-networks--id' struct instances. (erc-networks--id-sep): New variable for to help when formatting buffer names. (erc-obsolete-var): Define new generic context rewriter. (erc-networks-shrink-ids-and-buffer-names, erc-networks--refresh-buffer-names, erc-networks--shrink-ids-and-buffer-names-any): Add functions to reassess all network IDs and shrink them if necessary along with affected buffer names. Also add function to rename buffers so that their names are unique. Register these on all three of ERC's kill-buffer hooks because an orphaned target buffer is enough to keep its session alive. (erc-networks-rename-surviving-target-buffer): Add new function that renames a target buffer when it becomes the sole bearer of a name based on a target that has become unique across all sessions and, in most cases, all networks. IOW, remove the @NETWORK-ID suffix from the last remaining channel or query buffer after its namesakes have all been killed off. Register this function with ERC's target-related kill-buffer hooks. (erc-networks--examine-targets): Add new utility function that visits all ERC buffers and runs callbacks when a buffer-name collision is encountered. (erc-networks--qualified-sep): Add constant to hold separator between target and suffix. (erc-networks--construct-target-buffer-name, erc-networks--ensure-unique-target-buffer-name, erc-networks--ensure-unique-server-buffer-name, erc-networks--maybe-update-buffer-name): Add helpers to support `erc-networks--reconcile-buffer-names' and friends. (erc-networks--reconcile-buffer-names): Add new buffer-naming strategy function and helper for `erc-generate-new-buffer-name' that only run in target buffers. (erc-determine-network, erc-networks--determine): Deprecate former and partially replace with latter, which demotes RPL_ISUPPORT-derived NETWORK name to fallback in favor of known `erc-networks-alist' members as part of shift to network-based connection-identity policy. Return sentinel on failure. Expect `erc-server-announced-name' to be set, and signal when it's not. (erc-networks--name-missing-sentinel): Value returned when new function `erc-networks--determine' fails to find network name. The rationale for not making this customizable is that the value signifies the pathological case where a user of an uncommon IRC setup has not yet set a mapping from announced- to network name. And the chances of there being multiple unknown networks is low. (erc-set-network-name, erc-networks--set-name): Deprecate former and partially replace with latter. Ding with helpful message, and don't set `erc-network' when network name is not found. (erc-networks--ensure-announced): Add new fallback function to ensure `erc-server-announced-name' is set. Register with post-MOTD hooks. (erc-unset-network-name): Deprecate function unused internally. (erc-networks--insert-transplanted-content, erc-networks--reclaim-orphaned-target-buffers, erc-networks--copy-over-server-buffer-contents, erc--update-server-identity): Add helpers for `erc-networks--rename-server-buffer'. The first re-associates all existing target buffers that ought to be owned by the new server process. The second grabs buffer text from an old, dead server buffer before killing it. It then inserts that text above everything in the current, replacement server buffer. The other two massage the IDs of related sessions, possibly renaming them as well. They may also uniquify the current session's network ID. (erc-networks--init-identity): Add new function to perform one-time session-related setup. This could be combined with `erc-set-network-name'. (erc-networks--rename-server-buffer): Add new function to replace `erc-unset-network-name' as default `erc-disconnected-hook' member; renames server buffers once network is discovered; added to/removed from `erc-after-connect' hook on `erc-networks' minor mode. (erc-networks--bouncer-targets): Add constant to hold target symbols of well known bouncer-configuration bots. (erc-networks-on-MOTD-end): Add primary network-context handler to run on 376/422 functions, just before logical connection is officially established. (erc-networks-enable, erc-networks-mode): Register main network-setup handler with 376/422 hooks. * lisp/erc/erc.el (erc-rename-buffers): Change this option's default to t, remove the only instance where it's actually used, and make it an obsolete variable. (erc-reuse-buffers): Make this an obsolete variable, but take pains to ensure its pre-28.1 behavior is preserved. That is, undo the regression involving unwanted automatic reassociation of channel buffers during joins, which arrived in ERC 5.4 and effectively inverted the meaning of this variable, when nil, for channel buffers, all without accompanying documentation or announcement. (erc-generate-new-buffer-name): Replace current policy of appending a slash and the invocation host name. Favor instead temporary names for server buffers and network-based uniquifying suffixes for channels and query buffers. Fall back to the TCP host:port<n> convention when necessary. Accept additional optional params after the others. (erc-get-buffer-create): Don't generate a new name when reconnecting, just return the same buffer. `erc-open' starts from a clean slate anyway, so this just keeps things simple. Also add optional params. (erc-open): Add new ID param to for a network identifier explicitly passed to an entry-point command. This is stored in the `given' slot of the `erc-network--id' object. Also initialize the latter in new connections and otherwise copy it over. As part of the push to recast erc-networks.el as an essential library, set `erc-network' explicitly, when known, rather than via hooks. (erc, erc-tls): Add new ID keyword parameter and pass it to `erc-open'. (erc-log-irc-protocol): Use `erc--network-id' instead of the function `erc-network' to determine preferred peer name. (erc-format-target-and/or-network): This is called frequently from mode-line updates, so renaming buffers here is not ideal. Instead, do so in `erc-networks--rename-server-buffer'. (erc-kill-server-hook): Add `erc-networks-shrink-ids-and-buffer-names' as default member. (erc-kill-channel-hook, erc-kill-buffer-hook): Add `erc-networks-shrink-ids-and-buffer-names' and `erc-networks-rename-surviving-target-buffer' as default member. * test/lisp/erc/erc-tests.el (erc-log-irc-protocol): Use network-ID focused internal API. * test/lisp/erc/erc-networks-tests.el: Add new file that includes tests for the above network-ID focused functions. See bug#48598 for background on all of the above. |
