This ensures that if the child process closed its stdin and Emacs tries
to write to it, the process can still do any remaining work and exit
normally. In practice, this can occur with commands like "head(1)"
(bug#79079).
* src/fileio.c (file_for_stream): New function, extracted from...
(Fset_binary_mode): ... here.
(Ffile__close_stream): New function.
* src/process.c (send_process): When encountering EPIPE, only close the
fd for the pipe to the child process's stdin.
* lisp/eshell/esh-io.el (eshell-output-object-to-target): Don't check
for process liveness anymore.
* test/src/process-tests.el (process-tests/broken-pipe): New function.
(process-tests/broken-pipe/pipe, process-tests/broken-pipe/pty)
(process-tests/broken-pipe/pipe-stdin)

Clean up test process.
(process-test--check-pipe-process): New macro...
(process-test-make-pipe-process-no-buffer): ... call it.
* src/lisp.h (SAFE_ALLOCA_LISP_EXTRA): Remove. It is no longer
used, it makes life more difficult in the feature/igc3 branch,
and having it around tempted me to start using it again.
* src/editfns.c (styled_format): Don’t call SAFE_ALLOCA_LISP_EXTRA,
as this makes life more difficult in the feature/igc3 branch.
Also, allocate another byte for the format string trailing '\0',
so that we don’t rely in the str2num trick with trailing '\1'.
Problems reported by Pip Cet (Bug#81057#32).
Also, check alloca size more exactly. Ameliorate the extra
conditional branches by doing all the internal size calculations
before a conditional branch on overflow.
All tests now use 'jsonrpc--with-python-fixture' with a Python3
subprocess instead of the in-Emacs TCP server. Changed the "harakiri"
method to be a request instead of a notification for to reduce chance of
"Sentinel hasn't run" warning.
The two in-Emacs-RPC-specific error tests ('errors-with--32601' and
'signals-an--32603-JSONRPC-error') are dropped with the fixture itself,
as the error paths they exercise are internal to the Emacs Lisp
dispatcher and have no direct Python equivalent. They will have to be
re-done later on in other form.
* test/lisp/jsonrpc-resources/server-emacsrpc.py: New file.
* test/lisp/jsonrpc-resources/server-anxious-nested.py: Use new
harakiri.
* test/lisp/jsonrpc-resources/server-emacsrpc.py: Use new harakiri.

The fringe indicator uses a custom lightning-bolt bitmap, an alternative
to the margin indicator on GUI frames. It is non-interactive, however.
* lisp/progmodes/eglot.el (eglot--fringe-action): New fringe bitmap.
(eglot-code-action-indications): Add 'left-fringe' to default value
and to docstring. Update incompatibility note.
(eglot-code-action-suggestion): Handle 'left-fringe' indication.
Problem reported by Helmut Eller (Bug#81057).
On x86-64 this patch shrinks USEFUL_PRECISION_MAX
from 16382 to 1074, SPRINTF_BUFSIZE from 21318 to 1386,
and sizeof initial_buffer from 22318 to 2386.
This also fixes a problem reported privately by Pip Cet:
exactly formatting the smallest positive IEEE double 2**-1074
with %f needs %.1074f and 1074 is DBL_MANT_DIG - DBL_MIN_EXP,
not merely 1 - DBL_MIN_EXP.
* src/editfns.c (USEFUL_PRECISION_MAX, SPRINTF_BUFSIZE):
Base these on double, not long double, since long double
is not the worst case (it is used only for converted u?intmax_t).
(USEFUL_PRECISION_MAX): Add DBL_MANT_DIG - 1 as per Pip Cet.
* src/editfns.c (styled_format): Streamline allocation of
auxiliary tables, by allocating them all in one go
rather than via separate alloca / mallocs.
* lisp/calc/calc-embed.el (calc-embedded-update): Use
'buffer-substring' to better track the string representation of
the formula when it is being edited. Suggested by
gnu@publik.slmail.me. Also, update commentary. (Bug#80901)
* etc/NEWS: Document change.
* lisp/emacs-lisp/package-vc.el (package-vc--clone): Implement
logic to find and copy files from a previous installation.
(package-vc-install): Indicate the effect of the prefix argument
in the prompt.

Documentation is overwhelmingly prose and intended to be viewed,
not edited. Using visual-line-mode allows members of
'eldoc-doc-functions' to provide long lines that correctly fill
to the window width.
* lisp/emacs-lisp/eldoc.el (eldoc--format-doc-buffer): Use
visual-line-mode.
Eglot previously needed gfm-view-mode from markdown-mode.el to render
Markdown from LSP servers. It now prefers markdown-ts-view-mode when
available.
* lisp/progmodes/eglot.el (eglot--accepted-formats): Recognize
markdown-ts-view-mode as a Markdown renderer.
(eglot--format-markup): Rework with cl-labels; prefer
markdown-ts-view-mode over gfm-view-mode.
* doc/misc/eglot.texi (Eglot Features): Don't mention
markdown-mode directly.
* etc/EGLOT-NEWS: Mention change
Replace the "c" character-prompt interactive spec with
'read-multiple-choice', which presents named options instead of
requiring users to decode the prompt string and type a single
character.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts-table-align-column): Use 'read-multiple-choice'.
Adjust ALIGN docstring punctuation.
* lisp/textmodes/markdown-ts-mode-x.el
(markdown-ts-toc-insert-template): Use 'read-multiple-choice'.
This new derived mode is intended for consumers that render
Markdown content for display rather than editing, such as Eglot
and Eldoc when showing documentation popups and buffers. It
pre-sets the relevant customizations (markup hidden, inline
images on, hard-line-break markup hidden, native code-block
fontification, table and code-block context minor modes off),
makes the buffer read-only, and uses its own keymap derived from
'special-mode-map' so navigation keys behave like a viewer.
A pre-init hook lets callers normalize buffer content before the
grammar parses it; 'markdown-ts-add-final-newline' is the
default so that markup depending on a terminating newline parses
correctly. 'markdown-ts-buffer-string' returns the rendered
buffer string with overlay faces flattened into text properties,
which is useful for callers that capture the rendered output.
Along the way: 'list_marker_parenthesis' is now recognized as an
ordered list marker; the strikethrough query is simplified to a
single rule; thematic breaks span the window via an ':extend'
underline when the face supports it.
* lisp/textmodes/markdown-ts-mode.el (markdown-ts-view-mode):
New read-only derived mode.
(markdown-ts-view-mode-map): New keymap.
(markdown-ts-view-mode-pre-init-hook): New hook, defaulting to
'markdown-ts-add-final-newline'.
(markdown-ts-mode--initialize): New helper, factored out of
'markdown-ts-mode' so 'markdown-ts-view-mode' can reuse the
parser readiness and setup logic after overriding local
variables.
(markdown-ts-mode): Call 'markdown-ts-mode--initialize'.
(markdown-ts-add-final-newline): New function.
(markdown-ts-buffer-string): New function.
(markdown-ts-unordered-list-marker): New defcustom.
(markdown-ts-hard-line-break-backslash)
(markdown-ts-hard-line-break-space): Accept the symbol 'hide.
(markdown-ts--fontify-hard-line-break): Honor 'hide.
(markdown-ts--fontify-atx-heading)
(markdown-ts--fontify-setext-heading)
(markdown-ts--fontify-atx-delimiter)
(markdown-ts--fontify-unordered-list-marker)
(markdown-ts--list-item-depth): New functions supporting clean
rendering when markup is hidden.
(markdown-ts--fontify-thematic-break): Use ':extend' underline
span when the face supports it.
(markdown-ts--resolve-display-value): Accept non-cons values.
(markdown-ts--list-ordered-item-p): Also recognize
'list_marker_parenthesis'.
(markdown-ts--range-settings): Mark markdown-inline embed as
':local t'.
(markdown-ts--set-up): Create the markdown-inline parser only in
the inline setup branch; drop the redundant
'markdown-ts-hide-markup' make-local-variable.
(markdown-ts--treesit-settings): Route atx and setext headings
to their dedicated fontifiers; route unordered list markers
through 'markdown-ts--fontify-unordered-list-marker'; move
'strikethrough' to the simpler paragraph-inline query.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--treesit-settings): Add a new font-lock block for
'paragraph-inline' that handles strikethrough nodes more
carefully.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--treesit-settings): Move the 'code_span' and
'code_span_delimiter' font-lock rules into a separate block with
':override prepend' instead of 'append'. The heading feature
(level 1) applies its face via 'font-lock-append-text-property',
so a code span that later appends 'markdown-ts-code-span' ends
up with '(markdown-ts-heading-N markdown-ts-code-span)', where
the heading face takes priority and the code-span face is
suppressed. Prepending ensures 'markdown-ts-code-span' appears
first in the face list and wins visually.
* lisp/textmodes/markdown-ts-mode.el (markdown-ts-inline-images):
Now buffer local.
(markdown-ts--fontify-image): Defensively test for graphical
display before rendering images.
Since Emacs-27, `package-initialize` is for internal use only,
and callers should either call `package-activate-all` instead
(cheaper and faster) or do nothing at all (because the other
functions should trigger the needed initialization automatically
as needed).
* doc/lispref/package.texi (Packaging Basics): Delete `package-initialize`.
* doc/misc/eglot.texi (Reporting bugs): Don't recommend using `package-initialize`.
* doc/misc/org.org (Using Emacs packaging system): Simplify the command
line since both `(require 'package)` and `(package-initialize)` are
redundant here.
* etc/ERC-NEWS: Mention change.
* lisp/erc/erc.el (erc-connection-established): Apply `erc--open-target'
to all existing query buffers after they've been reassociated by
the erc-networks logic.
