* lisp/erc/erc-backend (erc--isupport-params): Add new variable to
hold a hashmap of parsed `erc-server-parameters' in a more useful
format. But keep `erc-server-parameters' around for public use. We
currently lack dedicated local variables for certain discovered IRC
session properties, such as what prefix characters are supported for
channels, etc. And the truth of this needs querying many times per
second at various points. As such, caching here seems justified but
can be easily removed if deemed otherwise because all ingredients are
internal.
(erc--parse-isupport-value): Add helper function that parses an
ISUPPORT value and returns the component parts with backslash-x hex
escapes removed. This can probably use some streamlining.
(erc--with-memoization): Add compat alias for use in internal ISUPPORT
getter. Should be moved to `erc-compat.el' when that library is fully
reincorporated.
(erc--get-isupport-entry): Add internal getter to look up ISUPPORT
items.
(erc-server-005): Treat `erc-server-response' "command args" field as
read-only. Previously, this field was set to nil after processing,
which was unhelpful to other parts of the library. Also call above
mentioned helper to parse values. And add some bookkeeping to handle
negation.
* lisp/erc/erc-capab.el (erc-capab-identify-send-messages): Use
internal ISUPPORT getter.
* lisp/erc/erc.el (erc-cmd-NICK, erc-parse-prefix,
erc-nickname-in-use): Use internal ISUPPORT getter.
* test/lisp/erc/erc-tests.el: Add tests for the above mentioned
changes in erc-backend.el.
* lisp/erc/erc.el: Require erc-networks.el, which ERC can't run
without these days. To sidestep the circular dependency, require it
last, just after erc-goodies. Remove the `declare-function' for
`erc-network-name' because it's not currently needed at load time.
(erc-log-irc-protocol, erc-hide-current-message-p): Remove `fboundp'
guard logic from `erc-network-name' invocations but preserve meaning
by interpreting `erc-network' being unset to mean module isn't loaded
or authoritative network detection has failed.
(erc-format-network): Likewise here. At the moment, this function
always returns the empty string because the function
`erc-network-name' always returns non-nil, perhaps from the
fallback/failure sentinel "Unknown", perhaps from the printed form of
nil.
* lisp/erc/erc-networks.el (erc-network): This is called throughout
erc.el but was previously cumbersome to use on account of being
guarded by `fboundp'. It now relies on the fact that its namesake
variable is set in target buffers as well.
* lisp/erc/erc.el (erc-open): whenever this function is called, the
variable `erc-server-announced-name' may be set locally in the calling
server buffer. However, if that buffer's dialed server matches that
of the one being created, the announced name is copied over on faith.
But there's no guarantee that the name will match the one ultimately
emitted by the server during its introductory burst. Beyond
potentially causing confusion in protocol logs, this behavior may
complicate debugging efforts. Setting the variable to nil helps
ensure a consistent environment when preparing a buffer for all newly
dialed connections. This commit also simplifies the setting of
`erc-server-connected', which is always nil when connecting and
vice-versa.
* lisp/erc/erc-backend (erc-server-send, erc-server-PING): Change name
of param `forcep' in `erc-server-send' to `force' and change its type
to the union of the symbol `no-penalty' and the set of all other
non-nil values. In `erc-server-PING', use this exemption when calling
`erc-server-send'. This fix was fast tracked and summarily
incorporated into bug#48598 because users of the soju bouncer are all
affected. See update #5 in the bug's email thread under the section
entitled "Riders" for an explanation.
* lisp/erc/erc-backend.el (erc--server-last-reconnect-count):
Add variable to record last reconnect tally.
* lisp/erc/erc.el (erc-reconnect-display): Add new option to specify
channel-buffer display behavior on reconnect.
(erc-setup-buffer): Use option `erc-reconnect-display' if warranted.
(erc-cmd-JOIN): Forget last reconnect count when issuing a manual
/JOIN command.
(erc-connection-established): Record reconnect count in internal var
before resetting.
(Bug#51753)
* lisp/erc/erc-backend.el (erc--unhide-prompt, erc--hide-prompt,
erc--unhide-prompt-on-self-insert): Add functions to ensure prompt is
hidden on disconnect and shown when a user types /reconnect in a
disconnected server buffer.
(erc-process-sentinel): Register aforementioned function with
`pre-command-hook' when prompt is deleted after disconnecting.
(erc-server-PRIVMSG): Ensure prompt is showing when a new message
arrives from target.
* lisp/erc/erc.el (erc-hide-prompt): Repurpose unused option by
changing meaning slightly to mean "selectively hide prompt when
disconnected." Also delete obsolete, commented-out code that at some
point used this option in its prior incarnation.
(erc-prompt-hidden): Add new option to specify look of prompt when
hidden.
(erc-unhide-query-prompt): Add option to force-reveal query prompts on
reconnect.
(erc-open): Augment earlier reconnect-detection semantics by
incorporating `erc--server-reconnecting'. In existing buffers, remove
prompt-related hooks and reveal prompt, if necessary.
(erc-cmd-RECONNECT): Allow a user to reconnect when already
connected (by first disconnecting).
(erc-connection-established): Possibly unhide query prompts.
(Bug#54826)
* test/lisp/erc/erc-tests.el (erc-tests--test-prep,
erc-tests--set-fake-server-process): Factor out some common
buffer-prep boilerplate involving user input and the server process.
Shared with bug#54536.
* lisp/erc/erc-backend.el (erc-server-reconnect): Reuse the username
argument from the previous session's USER command when reconnecting.
Also pass the existing client certificate, fixing an issue related to
bug#47788.
(erc-session-user-full-name): Move variable here from erc.el.
(erc-session-username): Add new local variable to store entry point
parameter.
* lisp/erc/erc.el (erc-session-user-full-name): Move variable to
erc-backend.
(erc-open, erc-determine-parameters, erc, erc-tls): Accept new
optional user parameter.
(erc-query): Preserve current `erc-session-username' when calling
`erc-open'.
(erc-login): Use `erc-session-username' instead of deriving it.
(erc-compute-user): Add new function to determine user name from
explicit argument or user options.
(Bug#54824)
* lisp/erc/erc-backend.el (erc-server-connect): Set
`erc-server-filter-data' to nil upon (re)connecting.
* lisp/erc/erc.el (erc-open): For the sake of clarity, don't
initialize `erc-server-filter-data' here because non-connect
invocations merely set up a target buffer and have no business
touching this variable.
* lisp/erc/erc.el: Declare needed variables exported by erc-backend.el
as special near the top of the file, and only require `erc-backend'
after providing `erc' as a feature at the very end.
* lisp/erc/erc-backend.el: Don't preemptively provide `erc-backend'.
* test/lisp/erc/erc-tests.el (erc--meta--backend-dependencies): Add
utility test to scrape for unused vars that may accumulate over time.
(Bug#54825)
* lisp/erc/erc-backend.el (define-erc-response-handler): Use
`format' here instead of `format-message' since Emacs will expand
the doc string later when the user asks for help about the symbols
defined.
* lips/erc/erc-dcc.el (erc-dcc-open-network-stream): Use TLS
for new connections when :secure flag is set.
(erc-dcc-do-GET-command): Set secure flag when user explicitly passes
an "-s" option.
(erc-dcc-do-LIST-command): Show an "s" to indicate a secure connection
when applicable.
(erc-dcc-query-handler-alist): Add extra items for "SSEND", etc.
(erc-dcc-handle-ctcp-send): Set secure flag when a leading "S" appears
in the command type.
* lisp/erc/erc-dcc.el (erc-dcc-list): Document optional :turbo item.
(erc-message-english-dcc-list-{head,line,item}): Adjust format strings
to make room for "(T)" turbo indicator.
(erc-dcc-do-GET-command): Optionally set :turbo in `erc-dcc-list'
entry when passed "-t" in the "/DCC GET" slash command. Also add
switch to command line in front-matter Commentary, but refrain from
publicizing further because our implementation is only defensive and
only for receiving.
(erc-dcc-do-LIST): Print message with new format specifier for turbo
status.
(erc-dcc-ctcp-query-send-regexp): Account for T- and S-prefixed
commands. Receiving from an SSEND-capable sender will be added in a
subsequent commit.
(erc-dcc-handle-ctcp-send): Set :turbo item in `erc-dcc-list' member
when new match group is nonempty.
(erc-dcc--X-send-final-turbo-ack): New internal variable and potential
future option for extreme corner cases involving maverick turbo
senders, like WeeChat, who don't use the TSEND command variant.
(erc-dcc-get-filter): Don't send when turbo is active.
* test/lisp/erc/erc-dcc-tests.el: Add new file.
(Bug#54458)
* lisp/erc/erc-dcc.el (erc-dcc-member): Be more tolerant in the
catch-all case by testing for equality instead of identity.
(erc-dcc-do-GET-command): Pass file name when querying
`erc-dcc-member'. (Bug#54458)
* lisp/erc/erc-dcc.el (erc-dcc-get-sentinel): Display error when total
byte count received is lower than expected.
(erc-message-english-dcc-get-failed): Add `dcc-get-failed' to the
English messages catalog.
(erc-dcc-get-file): Tweak initialization of `erc-dcc-entry-data'.
(Bug#54458)
Due to "The Orissa (Alteration of Name) Act, 2011"
(https://legislative.gov.in/sites/default/files/A2011-15.pdf)
Oriya has been renamed to Odia.
* lisp/language/indian.el (set-language-info-alist): Rename
Oriya to Odia. Improve Oriya composition rules.
* lisp/leim/quail/indian.el ("odia"): New input method.
* lisp/erc/erc-lang.el: Obsolete the iso-638-languages variable
(which was a typo) and replace it with iso-639-1-languages.
* etc/HELLO: Rename Oriya to Odia.
Replace the old Odia greeting with the new one.
Add a Hindi greeting separate from the Devanagari one.
(Bug#55493)
* lisp/erc/erc.el (erc--switch-to-buffer): Commit
f925fc93ba "Add `predicate' arg to
`read-buffer' and use it for erc-iswitchb" meant to remove this, but
it was left behind. (Bug#53617)
Copyright-paperwork-exempt: yes
* lisp/erc/erc.el (erc-cmd-QUERY): Be less enthusiastic about
announcing missing/broken functionality. The comment "except this is
broken right now" has been there since 2008, and it's not obvious to
me that we should ever re-add it.
* lisp/erc/erc.el (erc-cmd-default): prevent excess trailing newlines
from being sent.
* test/lisp/erc/erc-tests.el: Update `erc-process-input-line' test to
check for excess line feeds with unknown commands.
* lisp/erc/erc-backend.el (erc-server-reconnecting,
erc--server-reconnecting): obsolete and replace the former with new
internal variant, which carries a simplified meaning.
(erc-server-reconnect-p, erc--server-reconnect-p): Obsolete and
replace the former with an internal function, and change behavior to
disregard `erc-server-reconnecting' when rendering verdict.
(erc-process-sentinel-2): ensure local var `erc--server-reconnecting'
is t when timers are scheduled or firing, and nil otherwise, including
after retries exhausted. This agrees with the straightforward way
`erc-server-reconnecting' has always been used by `erc-cmd-RECONNECT'.
(erc-server-connect): set `erc--server-reconnecting'.
* lisp/erc/erc.el (erc-cmd-RECONNECT): use `erc--server-reconnecting'
instead of `erc-server-reconnecting'.
* lisp/erc/erc-backend.el (erc-server-reconnecting-p):
Don't consider erc-server-reconnecting when rendering verdict.
(erc-process-sentinel-2): ensure local variable
erc-server-reconnecting is t when timers are scheduled or running and
trying to reconnect, and nil otherwise, including after no retries
remain. Previously, its use and meaning in erc-backend were convoluted
and conflicted with its use in erc-cmd-RECONNECT (bug#50007).
* erc.el (erc-send-input-line): Previously, any line typed into a
query or channel buffer without an explicit user-command
handler (meaning most lines), would be sent twice because a trailing
newline (linefeed) would be appended. This has been verified by
checking IRCd server logs. IRCds won't return an error upon receiving
an empty message, but they also won't forward them to channel
subscribers and DM pals.
* erc-tests.el: Add test for erc-process-input-line, which also
indirectly tests erc-send-input-line. It also tests the command
lookup and dispatch facility (bug#50008).
* lisp/erc/erc-dcc.el (erc-dcc-member): Remove XEmacs compat code.
* lisp/erc/erc-goodies.el (erc-move-to-prompt-setup): Doc fix;
remove spurious reference to XEmacs; this is needed also for
Emacs.
That autoload file is created as part of the Emacs compilation
process, however we would like ERC to be usable if used outside
emacs.git (e.g. if installed from GNU ELPA).
* etc/ERC-NEWS: Announce the new command, and mention it at the top of
the file along with 'report-emacs-bug'.
* lisp/erc/erc.el (erc-bug): New command for reporting ERC bugs. It
prompts for a subject, and passes it on to 'report-emacs-bug' along
with the current ERC version, with the ERC mailing list in Cc.
