* lisp/eshell/esh-cmd.el (eshell-subcommand-bindings)
(eshell-command-to-value): Set 'eshell-in-pipeline-p' to nil.
* test/lisp/eshell/eshell-tests.el
(eshell-test/subcommand-reset-in-pipeline)
(eshell-test/lisp-reset-in-pipeline): New tests (bug#55620).
* test/lisp/erc/erc-dcc-tests.el
(erc-dcc-tests--dcc-handle-ctcp-send): Shadow hook to prevent the
erc-button module from interfering with tests that use this helper.
* lisp/eshell/esh-cmd.el (eshell-execute-pipeline): Use 'make-symbol'
for headproc and tailproc.
(eshell-do-pipelines, eshell-do-pipelines-synchronously): Adapt to the
above.
* test/lisp/eshell/eshell-tests.el (eshell-test/pipe-subcommand)
(eshell-test/pipe-subcommand-with-pipe): New test.
* doc/misc/eshell.texi (Bugs and ideas): Remove item about piping to
process from loop; this commit fixes it (bug#55590).
When printing a circular list and `print-circle` is nil, use a
somewhat more meaningful ". #N" tail index. The previous method for
calculating that index was based on Floyd circularity detection being
used so it had been broken ever since the change to Brent's algorithm.
The new index is correct with respect to the start of the list itself
which is what it used to be before being completely broken.
It does not take into account the nesting depth of the list context.
* src/print.c (struct print_stack_entry, print_object):
Keep track of the tortoise index (which is cheap) instead of trying
to derive it from the printed element index.
* test/src/print-tests.el (print-test-rho, print-circular):
New test.
* 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)
Python 3.10 introduced the "structural pattern matching" syntax, and
commit 139042eb86 told font-lock about the
new keywords. This adds them also as block-start statements, to enable
proper indentation of such blocks.
* lisp/progmodes/python.el (python-rx): Add "match" and "case" as
block-start keywords.
* test/lisp/progmodes/python-tests.el (python-indent-after-match-block,
python-indent-after-case-block): New tests to verify indentation of
"match" and "case" blocks (bug#55572).
* test/lisp/net/tramp-tests.el (tramp-fuse-remove-hidden-files): Declare.
(tramp-test16-directory-files)
(tramp-test16-file-expand-wildcards)
(tramp-test26-file-name-completion, tramp--test-check-files): Use it.
(tramp--test-check-files): Delete directory recursively.
(tramp-test43-file-system-info): Make test more robust.
In interactive calls, behave case-sensitively if the given char
is an upper-case character. Same for zap-up-to-char (Bug#54804).
This is analog to what the user-level incremental search feature does.
* lisp/misc.el (zap-up-to-char): Add an optional arg INTERACTIVE.
Perform a case-sensitive search when INTERACTIVE is non-nil and
CHAR is an upper-case character.
* lisp/simple.el (zap-to-char): Same.
* etc/NEWS (Editing Changes in Emacs 29.1): Announce this change.
* test/lisp/misc-tests.el (misc-test-zap-up-to-char): Add test cases.
* test/lisp/simple-tests.el (with-zap-to-char-test): Add helper macro.
(simple-tests-zap-to-char): Add a test.
* lisp/simple.el (escaped-string-quote): New variable.
(yank-in-context): New command.
(yank-in-context--transform): Helper function.
* lisp/progmodes/sh-script.el (sh-mode): Set up an
escaped-string-quote function.
* lisp/progmodes/sql.el (sql-mode): Define escaped-string-quote.
Introduce explicit stacks for traversing common data types during
printing: conses, vectors, records, byte-code, hash-tables and
char-tables, all previously traversed using recursion in C. This
greatly reduces the risk of crashing Emacs from C stack overflow
when printing deeply nested data.
* src/print.c (Fprinc, print, PRINT_CIRCLE_CANDIDATE_P):
Special-case Fprinc with a plain string argument to eliminate the need
for keeping track of print_depth during the preprocessing phase.
This also improves performance.
(struct print_pp_entry, struct print_pp_stack, ppstack)
(grow_pp_stack, pp_stack_push_value, pp_stack_push_values)
(pp_stack_empty_p, pp_stack_pop):
New stack for preprocessing.
(print_preprocess):
Make mostly nonrecursive, except for string properties.
(enum print_entry_type, struct print_stack_entry)
(struct print_stack, prstack, grow_print_stack)
(print_stack_push, print_stack_push_vector):
New stack for printing.
(print_vectorlike, print_object):
Make mostly nonrecursive, except for string properties and some less
heavily used types.
* test/src/print-tests.el (print-deeply-nested):
New test.
* lisp/textmodes/css-mode.el (css--selector-regexp): Recognize some
more SCSS selectors.
* test/lisp/textmodes/css-mode-resources/scss-selectors.txt: Add tests
for them.
* lisp/emacs-lisp/ert-x.el (ert-with-temp-file): Accept a new
keyword argument :coding CODING to use as the encoding when
writing initial text to the temporary file.
* test/lisp/mail/undigest-tests.el (rmail-undigest-test-rfc934-digest)
(rmail-undigest-test-rfc1153-digest-strict)
(rmail-undigest-test-rfc1153-less-strict-digest)
(rmail-undigest-test-rfc1153-sloppy-digest)
(rmail-undigest-test-rfc1521-mime-digest)
(rmail-undigest-test-multipart-mixed-digest): Force the temporary
mbox files to have Unix-style EOL format.
* doc/lispref/buffers.texi (Buffer Modification): Adjust
documentation.
* src/buffer.c (Frestore_buffer_modified_p): Fix up the logic
around `autosaved': It means "the buffer is modified, and also
autosaved".
Return non-nil if its argument is an uppercase character.
Suggested in Bug#54804.
* lisp/subr.el (char-uppercase-p): New defun.
* etc/NEWS (Lisp Changes in Emacs 29.1): Announce it
* doc/lispref/display.texi (Size of Displayed Text): Document it.
* test/lisp/subr-tests.el (test-char-uppercase-p): Add a test.
* lisp/emacs-lisp/bytecomp.el
(byte-compile--suspicious-defcustom-choice): New function (bug#16271).
(byte-compile-nogroup-warn): Use it to warn about forms like
(choice (const :tag "foo" 'bar)).
* doc/lispref/buffers.texi (Buffer Modification): Document
buffer-modified-p returning `autosaved'.
* lisp/subr.el (with-silent-modifications): Use
restore-buffer-modified-p instead of altering the buffer modiff
(since this has other side effects like not updating after async
`display' changes.
* src/buffer.c (Fbuffer_modified_p): Allow returning whether the
buffer has been autosaved after changes.
(Frestore_buffer_modified_p): Allow adjusting whether the buffer
has been autosaved after changes.
* src/fileio.c (Fdo_auto_save): Refill the doc string.
* doc/lispref/help.texi (Keys in Documentation): Document it.
lisp/help-mode.el (help-make-xrefs): Implement a new \+ syntax to
inhibit buttonification.
* lisp/subr.el (buffer-local-set-state)
(buffer-local-set-state--get, buffer-local-restore-state): Moved
from easy-mmode.el because they have to be available run-time.
* doc/lispref/modes.texi (Defining Minor Modes): Document it.
* lisp/emacs-lisp/easy-mmode.el (buffer-local-set-state): New macro.
(buffer-local-set-state--get): Helper function.
(buffer-local-restore-state): New function.
* lisp/textmodes/word-wrap-mode.el (word-wrap-whitespace-mode):
Use it to simplify code.
* test/lisp/net/tramp-tests.el (tar-mode): Require.
(tramp-test10-write-region-other-file-name-handler): New test.
(tramp-test31-interrupt-process, tramp-test31-signal-process):
Tag them :unstable unconditionally.
* test/lisp/net/tramp-resources/foo.tar.gz: New resource file.
Previously, concatenating a list to a string would first convert the
list to a string. Now, the string is concatenated with the last
element of the list.
* lisp/eshell/esh-util.el (eshell-to-flat-string): Make obsolete.
* lisp/eshell/esh-arg.el (eshell-concat, eshell-concat-1): New
functions.
(eshell-resolve-current-argument): Use 'eshell-concat'.
* test/lisp/eshell/esh-var-tests.el (esh-var-test/interp-concat-cmd):
Add check for concatenation of multiline output of subcommands.
(esh-var-test/quoted-interp-concat-cmd): New test.
* test/lisp/eshell/em-extpipe-tests.el (em-extpipe-test-13): Use
'eshell-concat'.
* doc/misc/eshell.texi (Expansion): Document this behavior.
* etc/NEWS: Announce the change (bug#55236).
This is closer in behavior to regular shells, and gives Eshell users
greater flexibility in how variables are expanded.
* lisp/eshell/esh-util.el (eshell-convert): Add TO-STRING argument.
* lisp/eshell/esh-var.el (eshell-parse-variable-ref): Add MODIFIER-P
argument and adjust how 'eshell-convert' and 'eshell-apply-indices'
are called.
(eshell-get-variable, eshell-apply-indices): Add QUOTED argument.
* test/lisp/eshell/esh-var-tests.el (eshell-test-value): New defvar.

* doc/misc/eshell.texi (Arguments): Expand this section, and document
the new behavior.
(Dollars Expansion): Provide more detail about '$(lisp)' and
'${command}' forms.
* etc/NEWS (Eshell): Announce this change (bug#55236).
* lisp/keymap.el (key-parse): Move the read-kbd-macro compat code
from here...
* lisp/subr.el (kbd): ... to here. (And fix the logic, too.)
This allows `key-parse' to have a less puzzling result while
maintaining backwards compatibility (bug#38775).
