Rather than blindly increase `max-lisp-eval-depth` when entering the
debugger or running `signal-hook-function`, use this new "reserve"
to keep track of how much we have grown the stack for "debugger"
purposes so that for example recursive calls to `signal-hook-function`
can't eat up the whole C stack.
* src/eval.c (max_ensure_room): Rewrite.
(restore_stack_limits): Move before `max_ensure_room`. Rewrite.
(call_debugger, signal_or_quit): Adjust calls accordingly.
Also grow `max-lisp-eval-depth` for `hander-bind` handlers.
(init_eval_once): Don't initialize `max_lisp_eval_depth` here.
(syms_of_eval): Initialize it here instead.
Add new var `lisp-eval-depth-reserve`.
* doc/lispref/eval.texi (Eval): Add `lisp-eval-depth-reserve`.
AFAIK, this provides the same semantics as Common Lisp's `handler-bind`,
modulo the differences about how error objects and conditions are
represented.
* lisp/subr.el (handler-bind): New macro.
* src/eval.c (pop_handler): New function.
(Fhandler_Bind_1): New function.
(signal_or_quit): Handle new handlertypes `HANDLER` and `SKIP_CONDITIONS`.
(find_handler_clause): Simplify.
(syms_of_eval): Defsubr `Fhandler_bind_1`.
* doc/lispref/control.texi (Handling Errors): Add `handler-bind`.
* test/src/eval-tests.el (eval-tests--handler-bind): New test.
* lisp/emacs-lisp/lisp-mode.el (lisp-font-lock-keywords):
Move 'handler-bind' from CL-only to generic Lisp.
(handler-bind): Remove indentation setting, it now lives in the macro
definition.
* lisp/minibuffer.el (completion-category-overrides): Doc fix.
* doc/emacs/mini.texi (Completion Options): Update documentation
of 'completions-sort'.
* doc/lispref/minibuf.texi (Completion Variables): Fox wording.
Add a cross-reference to where 'completions-sort' is documented.
* doc/lispref/minibuf.texi (Completion Variables):
Add 'display-sort-function' to the table of
'completion-category-overrides'.
* lisp/calendar/calendar.el (calendar-read-date): Add metadata
category 'calendar-month' for completing-read reading a month name.
* lisp/minibuffer.el (completion-category-defaults):
Add 'display-sort-function' with identity for the category 'calendar-month'.
(completion-category-overrides): Add customization for completion sorting
with 'display-sort-function' and a choice like in 'completions-sort'.
(completion-metadata-override-get): New function.
(minibuffer-completion-help): Use 'completion-metadata-override-get'
instead of 'completion-metadata-get' to get sort-fun from
'display-sort-function'.
Remove from the English version any ignore'd chunk of text that has
been contributed yet only in the French version, and let only the
comment indicating re-alignment is needed.
* src/buffer.h: Remove case_fold_search_ buffer object slot.
* src/buffer.c (bset_case_fold_search): Remove - no longer needed.
(init_buffer_once): Remove removed buffer slot init.
(syms_of_buffer): Use DEFVAR_LISP to define `case-fold-search' and
declare it buffer-local.
* src/minibuf.c (syms_of_minibuf): Remove DEFSYM call for
`case-fold-search' symbol. It now lives in `syms_of_buffer'.
* src/editfns.c (Fcompare_buffer_substrings):
(Fchar_equal):
* src/search.c (looking_at_1):
(string_match_1):
(search_command):
(Fre__describe_compiled): Adjust C queries to `case-fold-search' value
to use C globals instead of BVAR macro.
* doc/lispref/internals.texi (Buffer Internals): Do not list
`case_fold_search' slot.
See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66117#259
When used as buffer slot, let-binding `case-fold-search' would scale
with the number of live buffers and can be slow. This change makes
let-binding much faster at the cost of slightly slower `set-buffer'.
cd61af0 changed from default-major-mode to major-mode in the first
code sample but didn't change the rest. This patch fixes this and add
some explanations of why use `setq-default' instead of `setq'. In
addition, it gives background on suggesting using text-mode as default
mode and suggest other alternatives.
* doc/lispintro/emacs-lisp-intro.texi (Text and Auto-fill): Fix usage
of `setq-default' and offer more suggestions. (Bug#67848)
* doc/misc/erc.texi (auth-source): Add new "Troubleshooting"
subsection.
* lisp/erc/erc.el (erc-open): Initialize markers before determining
session parameters. Otherwise, functions that rely on
`erc-inset-marker' being non-nil, like `erc-check-text-conversion',
may fail during auth-source lookups.
(erc-auth-source-search): When non-interactive, ask the user whether
to continue connecting anyway. (Bug#67978)
* doc/misc/eglot.texi (Project-specific configuration): Recommend
setting directory local variables for 'python-base-mode' instead of
'python-mode'. This makes any customizations effective also for
'python-ts-mode'.
* doc/misc/tramp.texi (Remote processes): Remove item about
tramp-remote-path.
* etc/NEWS: Direct asynchronous processes use 'tramp-remote-path'.
* lisp/net/tramp-sh.el (tramp-get-remote-pipe-buf): New defun.
(tramp-set-remote-path): Use it.
(tramp-get-remote-path): Add ;;;###tramp-autoload cookie.
* lisp/net/tramp.el (tramp-handle-make-process):
Use `tramp-remote-path' for setting PATH environment.
* test/lisp/net/tramp-tests.el (tramp-test35-exec-path-direct-async)
(tramp-test35-remote-path-direct-async): New tests.
* doc/lispintro/emacs-lisp-intro.texi (Using set): Delete.
(Using setq): Adjust accordingly.
(setq): Rename from "set & setq" and don't refer to `set` any more.
(Review): Don't mention `set` any more.
The time stamp format in the chat buffer may now
differ from the format in the log files.
* doc/misc/rcirc.texi: Document new variable
* lisp/net/rcirc.el (rcirc-log-time-format):
Custom variable for the format. (bug#67597)
Copyright-paperwork-exempt: yes
* doc/misc/erc.texi: Replace option `erc-format-nick-function' with
`erc-show-speaker-membership-status'.
* etc/ERC-NEWS: Mention shift to template-based speaker formatting.
Also mention in-buffer STATUSMSG support and various name changes and
new formatting-related options.
* lisp/erc/erc-backend.el (erc-format-privmessage): Remove forward
declaration.
(erc--determine-speaker-message-format-args): Add forward declaration.
(erc--statusmsg-target): New utility function for detecting whether
the current target is status-prefixed.
(erc-current-message-catalog): Move here from lisp/erc/erc.el.
(erc--message-speaker-catalog): New variable.
(erc--speaker-status-prefix-wanted-p): New variable specifically for
the function `erc-format-@nick' to signal it wants status-prefixes
prepended to the displayed nick.
(erc-server-PRIVMSG): Initialize `let'-bound value of
`erc--msg-prop-overrides' to a dummy `erc--tmp' property with a null
value that `erc-display-message' will "strip" before calling its
hooks. Move away from the rather blunt symbol `msg' as a useful value
for `erc--msg'. Instead, allow `erc-display-message' to assign the
most appropriate value based on context. Also, bind the variable
`erc-current-message-catalog' to whatever the buffer's
`erc--message-speaker-catalog' happens to be. Future internal modules
can set this to alternative catalogs as needed. Additionally, detect
STATUSMSG prefixes on targets and inform the formatting logic of the
verdict. Lastly, and most importantly, use the function
`erc--determine-speaker-message-format-args' instead of
`erc-format-privmessage' for message formatting. Pass along the
returned "catalog key" and spec parameters to `erc-display-message'.
However, for NOTICEs, continue to render the string, as before, for
the two "echo notice" hooks.
* lisp/erc/erc-common.el (erc--ctcp-response): New "subsclass" of
`erc-response' for smuggling extra information to CTCP query handlers
in a mostly backwards-compatible way. The same approach could be
taken with the "echo notice" hooks mentioned above.
* lisp/erc/erc-dcc.el (erc-dcc-chat-filter): Add `erc--spkr' and
`erc--speaker' properties even though these chat buffers are not
`erc-mode' buffers.
* lisp/erc/erc-fill.el (erc-fill--wrap-last-msg,
erc-fill--wrap-max-lull): Add doc strings.
(erc-fill--wrap-continued-message-p): Rework to look for `erc--spkr'-
`erc--msg' combinations as indicators of speaker continuity.
(erc-fill--wrap-rejigger-region): Remove reference to the no longer
relevant `erc-stamp-type'. Instead, use the `erc--msg' property
combined with the `erc-timestamp' field to detect date stamps because
all are currently left-sided.
* lisp/erc/erc-stamp.el (erc-stamp--propertize-left-date-stamp): Don't
add superfluous `erc-stamp-type' property.
* lisp/erc/erc.el (erc--msg-props): Revise purpose and meaning of
`erc--msg' by removing possible value `msg', which was previously
meant to indicate that a message had a "speaker". Instead, rely on
the separate `erc--spkr' property to convey this information, with
`erc--msg' now expressing a "type" or "role".
(erc--use-language-catalog-for-ctcp-action-p): New variable, a
compatibility switch to help transition from the `ACTION' entry of the
language catalog to the `ctcp-action' family of entries in the new
`-speaker' catalog.
(erc--ensure-spkr-prop): Update to include any passed-in environmental
overrides.
(erc--send-action-display): Restore pre-5.6 behavior when
compatibility flag enabled. Otherwise, use new `-speaker' catalog for
formatting inserted message.
(erc--send-message-external): Overhaul to behave more faithfully in
mimicking a line submitted at the prompt of the current target buffer.
(erc--own-property-names): Remove `erc-stamp-type'.
(erc-ensure-target-buffer-on-privmsg): Add new choice variant for old
default behavior and change meaning of default to mean "except for
STATUSMSGs". This option is newly revived for ERC 5.6.
(erc--message-speaker-statusmsg, erc--message-speaker-statusmsg-input,
erc--message-speaker-input, erc--message-speaker-input-chan-privmsg,
erc--message-speaker-input-chan-notice,
erc--message-speaker-input-query-privmsg,
erc--message-speaker-input-query-notice,
erc--message-speaker-chan-privmsg, erc--message-speaker-query-privmsg,
erc--message-speaker-chan-notice, erc--message-speaker-query-notice,
erc--message-speaker-ctcp-action,
erc--message-speaker-ctcp-action-input,
erc--message-speaker-ctcp-action-statusmsg,
erc--message-speaker-ctcp-action-statusmsg-input): New variables for
new `speaker' format-template catalog.
(erc--speakerize-nick): New helper function.
(erc--determine-speaker-message-format-args): New function to find the
appropriate format key from various contextual parameters. Could
become the default of a function-valued variable for internal use.
(erc-show-speaker-membership-status): New option.
(erc-format-nick-function, erc-speaker-from-channel-member-function):
Declare former as an obsolete alias for the latter, and redefine
purpose slightly.
(erc-format-nick-function, erc-determine-speaker-from-user): Rename
former to latter and obsolete the old name.
(erc-format-nick, erc-determine-speaker-from-user): Rename former to
latter and obsolete old name.
(erc-format-@nick): Deprecate and adapt for use with new
template-based formatting paradigm.
(erc-format-my-nick): Move `erc-speaker' text prop toward head of
list, meaning it will end up beneath `font-lock-face' in the final
output.
(erc--format-speaker-input-message): New function to replace
`erc-format-my-nick' in-tree.
(erc-process-ctcp-query): Don't bind `erc--msg' to `msg'. Instead,
rely on `erc-display-message' to set it to the current template key.
(erc-ctcp-query-ACTION): Prefer using formatting template, but attempt
to simulate pre-5.6 behavior when compatibility flag enabled.
(erc-display-msg): Use `erc--format-speaker-input-message' instead of
`erc-format-my-nick'. Ignore `erc--msg-prop-overrides' with null
values.
(erc-current-message-catalog): Move to erc-backend.el.
* test/lisp/erc/erc-scenarios-base-statusmsg.el: New file.
* test/lisp/erc/erc-scenarios-stamp.el
(erc-scenarios-stamp--left/display-margin-mode): Expect format catalog
key instead of unhelpful `msg' as value of `erc--msg' prop.
* test/lisp/erc/erc-tests.el (erc-message): Render format template in
mock function and expect string in assertions.
(erc-tests--format-privmessage): New function, a helper for the
following test.
(erc-format-privmessage, erc--determine-speaker-message-format-args):
Rename former to latter and suppress deprecation warning.
(erc--determine-speaker-message-format-args/queries,
erc--determine-speaker-message-format-args/queries-as-channel): New
tests.
(erc-tests--format-my-nick): New helper function for the following
test.
(erc--format-speaker-input-message): New test.
* test/lisp/erc/resources/base/display-message/statusmsg.eld: New
file. (Bug#67677)
; * test/lisp/erc/resources/fill/snapshots/merge-wrap-01.eld: Update.
; * test/lisp/erc/resources/fill/snapshots/merge-wrap-indicator-post-01.eld:
; Update.
; * test/lisp/erc/resources/fill/snapshots/merge-wrap-indicator-pre-01.eld:
; Update.
It used to be possible to customize 'url-privacy-level' so that the
user's email address was sent along in HTTP requests. Since
'url-privacy-level' is also a blocklist, rather than an allowlist,
this meant that a mere misconfiguration of Emacs risked exposing the
user's email address. This is a serious privacy risk, and it is thus
better if we remove this dangerous feature altogether.
* lisp/url/url-http.el (url-http-create-request): Never send the
user email address.
* lisp/url/url-vars.el (url-personal-mail-address): Make obsolete.
* lisp/url/url-privacy.el (url-setup-privacy-info): Don't set
above obsolete variable.
* doc/misc/url.texi (Customization):
* lisp/url/url-vars.el (url-privacy-level): Update documentation
to reflect the above changes.
* doc/misc/gnus.texi (Delayed Articles): As of commit 7725fbc5b this
paragraph is no longer true; the "Date" header is not included in
`message-draft-headers' by default.
