* src/intervals.h (INTERVAL_VISIBLE_P): Split into ...
(INTERVAL_GENERALLY_WRITABLE_P, INTERVAL_EXPRESSLY_WRITABLE_P):
... two new macros.
* src/textprop.c (verify_interval_modification): If the buffer
is read only, verify not that there is only a single exempting
interval spanning the area of a multiple-character operation,
but that every intervening interval in such an operation exempts
it from write restrictions, either by providing a read-only
property that appears in Vinhibit_read_only, or by providing an
inhibit-read-only property.
* test/src/textprop-tests.el (textprop-interval-immutability):
New test.
* src/lisp.h (tim_sort): Require array arg to be nonnull.
* src/sort.c (reverse_slice): Omit no-longer-needed eassert.
(tim_sort): Avoid undefined behavior when length == 0,
since reverse_slice would then compute &seq[-1].
* src/xterm.c (x_dpyinfo): New function, which acts like
x_display_info_for_display except it always returns nonnull.
This simplifies callers and pacifies GCC 14. All callers changed.
* lib-src/etags.c: Ignore -Wanalyzer-use-of-uninitialized-value.
This applies to the whole source file, not just to areas where GCC
has bugs, as it was too tricky to ignore more selectively.
* lib-src/etags.c (readline): Don’t mishandle lines like
‘#line 1 "a//"’, which has an escaped backslash before ‘"’.
Don’t mishandle lines so long that sscanf overflows %n.
* lib-src/etags.c (xnew): Remove. All uses removed.
xnew was confusing, as sometimes it was used with n=1,
sometimes with Type=char, and it’s easier just to use xmalloc
or xnmalloc.
* lisp/net/eww.el (eww-check-text-conversion): Fix doc string.
(eww-mode): Specify face, eww-form and field as nonsticky
properties by default.
(eww-tag-textarea, eww-form-text): Render properties
front-sticky.
(eww-process-text-input): Use field functions to compute field
bounds.
* lisp/gnus/gnus.el (gnus-valid-select-methods): We need a value for
post/mail/none in order to conform to the option type.
* lisp/gnus/nnatom.el: This call to gnus-declare-backend does the exact
same thing as above, and needs to be adjusted accordingly.
It has been effectively obsolete since Emacs 27, when the modern
extension mechanism was introduced.
* lisp/emacs-lisp/rx.el (rx-constituents): Make obsolete.
* test/lisp/emacs-lisp/rx-tests.el (rx-constituents): Suppress warning.
* etc/NEWS: Announce.
It is not intended for the human reader, but to give less wrong versions
of first appearance displayed by `describe-function` or
`describe-variable` that would otherwise be derived from a notice in a
more recent NEWS* file.
It is better to add items to this file than changing historical NEWS*
files when the actual version of introduction is not known.
* etc/NEWS.unknown: New file. Add entry for `nthcdr`.
It's a common name for this function and symmetric with respect to
`take`. It's also a lot less awkward to type and say.
* lisp/subr.el (drop): New alias.
* doc/lispref/lists.texi (List Elements): Document. Mention the
equation tying `take` and `drop` together.
* etc/NEWS: Announce.
* src/fns.c (string_cmp): Fix bad comparisons for certain strings.
This only affected `value<` for aggregates, not `string<`.
* test/src/fns-tests.el (fns-value<-ordered): Add test cases.
* doc/emacs/input.texi (On-Screen Keyboards): Update conditions
for displaying the virtual keyboard when t-s-d-k is enabled.
* etc/NEWS (Announce): Document changes.
* lisp/net/eww.el (eww-check-text-conversion): New function.
(eww-mode): Install it as a local post-command-hook.
(eww-submit-map, eww-submit-file, eww-checkbox-map): Bind
suitable commands to mouse-2.
(eww-form-submit, eww-form-checkbox, eww-form-file)
(eww-tag-select): Disguise inserted forms as buttons, that touch
event translation may prefer their bindings to mouse-2 over
mouse-1.
(eww-form-text, eww-tag-textarea): Insert field properties as
well.
(eww-select-file, eww-toggle-checkbox, eww-submit): New argument
EVENT, to whose position point is set.
* lisp/touch-screen.el (touch-screen-handle-point-up): Trivial
adjustments to the criteria for selecting mouse commands and
displaying the on screen keyboard.
* lisp/cus-edit.el (Custom-mode): Enable text conversion, now
that fields are correctly treated.
* src/alloc.c (mark_frame): Mark f->conversion.field.
* src/androidterm.c (android_update_selection): Adjust
conversion region and selection position by the field start and
end.
* src/editfns.c (find_field): Export function.
* src/frame.c (make_frame): Clear f->conversion.field.

functions.

if Voverriding_text_conversion_style is set.

(reset_frame_conversion): New function.
(reset_frame_state): Clear conversion field.
(really_delete_surrounding_text): Narrow to field.
(locate_and_save_position_in_field): New function.
(really_request_point_update, really_set_point_and_mark)
(complete_edit_check, handle_pending_conversion_events_1)
(handle_pending_conversion_events, get_conversion_field)
(set_composing_region, textconv_set_point_and_mark, replace_text)
(get_extracted_text, get_surrounding_text, report_point_change):
Compute, narrow to and offset by the currently active field
whenever point is updated or a command is received.
(syms_of_textconv): Revise doc strings.
* src/textconv.h (get_conversion_field): Export function.
Change `function` so that when evaluating #'(lambda ...)
we return an object of type `interpreted-function` rather than
a list starting with one of `lambda` or `closure`.
The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED)
tag and tries to align the corresponding elements:
- the arglist, the docstring, and the interactive-form go in the
same slots as for byte-code functions.
- the body of the function goes in the slot used for the bytecode string.
- the lexical context goes in the slot used for the constants of
bytecoded functions.
The first point above means that `help-function-arglist`,
`documentation`, and `interactive-form`s don't need to
distinguish interpreted and bytecode functions any more.
Main benefits of the change:
- We can now reliably distinguish a list from a function value.
- `cl-defmethod` can dispatch on `interactive-function` and `closure`.
Dispatch on `function` also works now for interpreted functions but still
won't work for functions represented as lists or as symbols, of course.
- Function values are now self-evaluating. That was alrready the case
when byte-compiled, but not when interpreted since
(eval '(closure ...)) signals a void-function error.
That also avoids false-positive warnings about "don't quote your lambdas"
when doing things like `(mapcar ',func ...)`.

advantage of the fact that function values are now self-evaluating.

* doc/lispref/lists.texi (Rearrangement):

In preparation for the use of `PVEC_COMPILED` objects for
interpreted functions, rename them to use a more neutral name.
* src/lisp.h (enum pvec_type): Rename `PVEC_COMPILED` to `PVEC_CLOSURE`.

Also use `CODE` rather than `BYTECODE`.
