* src/process.c (process-tty-name): Add STREAM argument.
* lisp/eshell/esh-io.el (eshell-close-target): Only call
'process-send-eof' once if the process's stdin is a pipe.
* test/src/process-tests.el (make-process/test-connection-type): Check
behavior of 'process-tty-name'.
* doc/lispref/processes.texi (Process Information): Document the new
argument.
* etc/NEWS: Announce this change.
* src/lisp.h (emacs_spawn):
* src/callproc.c (emacs_spawn): Add PTY_IN and PTY_OUT arguments to
specify which streams should be set up as a PTY.
(call_process): Adjust call to 'emacs_spawn'.
* src/process.h (Lisp_Process): Replace 'pty_flag' with 'pty_in' and
'pty_out'.
* src/process.c (is_pty_from_symbol): New function.
(make-process): Allow :connection-type to be a cons cell, and allow
using a stderr process with a PTY for stdin/stdout.
(create_process): Handle creating a process where only one of stdin or
stdout is a PTY.
* lisp/eshell/esh-proc.el (eshell-needs-pipe, eshell-needs-pipe-p):
Remove.
(eshell-gather-process-output): Use 'make-process' and set
':connection-type' as needed by the value of 'eshell-in-pipeline-p'.
* lisp/net/tramp.el (tramp-handle-make-process):
* lisp/net/tramp-adb.el (tramp-adb-handle-make-process):
* lisp/net/tramp-sh.el (tramp-sh-handle-make-process): Don't signal an
error when ':connection-type' is a cons cell.
* test/src/process-tests.el
(process-test-sentinel-wait-function-working-p): Allow passing PROC
in, and rework into...
(process-test-wait-for-sentinel): ... this.
(process-test-sentinel-accept-process-output)
(process-test-sentinel-sit-for, process-test-quoted-batfile)
(process-test-stderr-filter): Use 'process-test-wait-for-sentinel'.
(make/process/test-connection-type): New function.
(make-process/connection-type/pty, make-process/connection-type/pty-2)
(make-process/connection-type/pipe)
(make-process/connection-type/pipe-2)
(make-process/connection-type/in-pty)
(make-process/connection-type/out-pty)
(make-process/connection-type/pty-with-stderr-buffer)
(make-process/connection-type/out-pty-with-stderr-buffer): New tests.
* test/lisp/eshell/esh-proc-tests.el (esh-proc-test--detect-pty-cmd):
New variable.
(esh-proc-test/pipeline-connection-type/no-pipeline)
(esh-proc-test/pipeline-connection-type/first)
(esh-proc-test/pipeline-connection-type/middle)
(esh-proc-test/pipeline-connection-type/last): New tests.
* doc/lispref/processes.texi (Asynchronous Processes): Document new
':connection-type' behavior.
(Output from Processes): Remove caveat about ':stderr' forcing
'make-process' to use pipes.
* etc/NEWS: Announce this change (bug#56025).
* lisp/emacs-lisp/loaddefs-gen.el (autoload-ignored-definitions):
Add another semantic function.
(loaddefs-generate--compute-prefixes): Allow newline after the "(def*"
form. (Bug#57000)
https://mail.gnu.org/archive/html/emacs-devel/2022-07/msg01127.html
points out that end-users can get bitten by this, accidentally
calling `timer-activate` on an already activated timer.
* lisp/emacs-lisp/timer.el (timer--activate): Signal an error if we try
to re-add a timer that's already on the timer-list.
* src/xdisp.c (init_iterator): Always initialize narrowed_begv to
zero, since SET_WITH_NARROWED_BEGV depends on it being non-zero as
an indication that long-line optimizations are in use.
(back_to_previous_visible_line_start): When long-line
optimizations are in effect, we may end up not on a newline.
* lisp/emacs-lisp/bytecomp.el (byte-compile-output-docform): Don't
insert a \n before the #@ docstrings since make-docfile doesn't scan
.elc files any more.
* src/Makefile.in (LC_ALL): Add loaddefs.el as a dependency, too,
since that file may be deleted, but the loaddefs.elc file still
exists. This causes problems in nativecomp builds.
* lisp/emulation/viper.el
(viper-this-major-mode-requires-vi-state): Rename from
'this-major-mode-requires-vi-state'. Retain old name as an
obsolete alias.
(viper-set-state-in-major-mode): Rename from
'set-viper-state-in-major-mode'. Retain old name as an obsolete
alias.
* lisp/progmodes/xscheme.el (xscheme-default-runlight): Rename
from 'default-xscheme-runlight'. Retain old name as an obsolete
alias.
(xscheme-verify-buffer): Rename from 'verify-xscheme-buffer'.
Retain old name as an obsolete alias.
* lisp/saveplace.el (save-place-load-alist-from-file): Rename from
'load-save-place-alist-from-file'. Retain old name as an obsolete
alias. Update callers.
* lisp/textmodes/emacs-news-mode.el (emacs-news-mode-map)
(emacs-news-view-mode-map): Make C-x C-q switch to the
appropriate mode for editing, and vice versa.
(emacs-news-mode): Disable button-mode and make buffer
read-write.
* etc/TODO: Document that MPX support still needs work.
* src/xterm.c (xi_handle_interaction): New function.
(handle_one_xevent): Call it in the appropriate places.
* src/xterm.c (x_cache_xi_devices): Initialize device fields to
0.
(xi_handle_focus_change, xi_focus_handle_for_device)
(xi_handle_delete_frame): New functions; store focus information
per-device instead.
(x_detect_focus_change): Handle GenericEvents that way instead.
(handle_one_xevent): Don't cache XI devices on DeviceChanged.
(x_free_frame_resources): Clear any frame focus information.
* src/xterm.h (struct xi_device_t): New fields for focus
tracking. Add comments describing fields.
* lisp/emacs-lisp/loaddefs-gen.el
(loaddefs-generate--compute-prefixes): Allow tabs and spaces before
symbol name, so that "(defvar\tfoo-bar nil)" is properly picked up.
Before this change, such a definition would be wrongly picked up as
the symbol "nil".
