* src/haiku_support.cc (class EmacsWindow): New fields
`menu_update_cv', `menu_update_mutex' and `menu_updated_p'.
(~EmacsWindow): Destroy cv and mutex.
(MenusBeginning): Release lock and wait for condition to be
become true.
(EmacsWindow_signal_menu_update_complete): New function.
* src/haiku_support.h (struct haiku_menu_bar_state_event): New
field `no_lock'.
* src/haikumenu.c (Fhaiku_menu_bar_open): Always update menu
bar.
* src/haikuterm.c (haiku_read_socket): Always update menu bar
and signal the window thread after update completion.
* lisp/emacs-lisp/cl-generic.el (cl--generic-lambda): `commandp` and
`interactive-form` are for function values, not for source code.
* lisp/cedet/semantic/db-el.el (semanticdb-elisp-sym->tag):
Prefer `commandp` over `interactive-form`.
When using eshell-match-result via eshell-command-result-p to examine
the output of asynchronous Eshell commands, a newly emitted prompt is
included in the text against which the regexp is matched. This makes
it awkward to match against the whole output; for example, to check
whether it is empty. Rework the function to exclude the prompt.
* test/lisp/eshell/eshell-tests-helpers.el (eshell-match-result):
Exclude any newly emitted prompt from the text against which the
regexp is matched. Additionally, the function no longer moves point.
* test/lisp/eshell/eshell-tests.el (eshell-test/flush-output): Update
and simplify test given how eshell-match-result no longer moves point.
* etc/e/eterm-color.ti: Added termcaps for entering and leaving an
alternative sub-buffer.
* lisp/term.el (term-reset-size): Resize correctly in an alternative
sub-buffer is in use.
(term-clear-full-screen-programs): New user option.
(term-handle-ansi-escape):
(term-termcap-format): Handle termcaps for entering and leaving an
alternative sub-buffer.
(term-switch-to-alternate-sub-buffer): New (used to be commented out)
function to enter or leave an alternative sub-buffer.
bug#53485
Rebind [header-line mouse-1] from mouse-select-window to
Info-mouse-follow-link. It selects the window anyway,
but also allows repetitively clicking on the Next button
on the Info header line (bug#53170).
When MULTIPLE is nil and the arg DEFAULT is a list, keep its elements
in the "future history" of the minibuffer retrieved by `M-n M-n ...'.
(bug#53255)
* src/keyboard.c (read_char): Don't touch the echo area if
Vecho_keystrokes is nil.
* src/lread.c (read_filtered_event): Bind echo_keystrokes to nil
to avoid outputting prefixes we're not going to act on anyway
(bug#19718).
* etc/NEWS: Document the new user option.
* lisp/minibuffer.el (completions-sort): Add new user option.
(minibuffer-completion-help): Implement it for the Completions
buffer. (Bug#53362)
* lisp/emacs-lisp/ert.el (ert-test):
(ert-deftest): Store the file name.
(ert-test-location): New function.
(ert-run-tests-batch): Use it.
* lisp/emacs-lisp/find-func.el (find-ert-deftest-regexp): New
variable.
(find-function-regexp-alist): Add ert-deftest (bug#22471).
Based on code by Phillip Lord <phillip.lord@russet.org.uk>.
* doc/emacs/help.texi (Help Mode): Document it.
* lisp/help-mode.el (help-mode-map): Add an `I' keystroke.
(help-goto-lispref-info): New command.
* lisp/info-look.el (:mode): Add an entry for the lispref manual.
Since `maybe_quit` is called on many critical paths, inline a slightly
cheaper condition (that ignores Vinhibit_quit).
* src/eval.c (maybe_quit): Rename to `probably_quit`.
* src/lisp.h (maybe_quit): New simplified inline function.
The common case is just to increment `specpdl_ptr`; do that in-line,
but move the uncommon reallocation to a separate subroutine.
* src/eval.c (grow_specpdl): Now inline, most code moved...
(grow_specpdl_allocation): ...here.
* src/eval.c (funcall_general, Ffuncall): Delegate the actual work in
Ffuncall to funcall_general which does exactly this.
This slows down some less used function call paths by a small amount
but the code duplication was just silly.
* src/bytecode.c (exec_byte_code): Inline aref and aset for
vectors and records, since this is important for code that makes heavy
use of arrays and/or objects.
It was implemented but never generated, originally intended for
TCO in the pre-lexbind era (which was semantically dubious anyway).
Removing it speeds up the interpreter because there is no longer any
need for the outermost `count` variable unless checking is enabled.
* lisp/emacs-lisp/bytecomp.el:
* lisp/emacs-lisp/comp.el (comp-limplify-lap-inst):
* src/bytecode.c (BYTE_CODES, exec_byte_code):
Remove definition and implementation of unbind-all, freeing up the opcode
for other purposes.
* src/bytecode.c (exec_byte_code): Perform bytecode unwinding error
check only when building with debugging (NDEBUG not defined, checking
enabled, or BYTE_CODE_SAFE enabled). This improves speed in several
ways.
Since we pass no arguments to a non-lexbind bytecode function, we can
specify its arity as 0 instead of nil and save a test and branch.
* src/bytecode.c (Fbyte_code, exec_byte_code):
* src/eval.c (fetch_and_exec_byte_code, funcall_lambda):
* src/lisp.h:
Change the args_template parameter type to ptrdiff_t, since it is now
always a small integer, in exec_byte_code and
fetch_and_exec_byte_code, all callers adjusted.
Avoid making a copy (in the interpreter C stack frame) of the bytecode
string by making sure it won't be moved by the GC. This is done by
reallocating it to the heap normally only used for large strings,
which isn't compacted.
This requires that we retain an explicit reference to the bytecode
string object (`bytestr`) lest it be GCed away should all other
references vanish during execution. We allocate an extra stack slot
for that, as we already do for the constant vector object.
* src/alloc.c (allocate_string_data): Add `immovable` argument.
(resize_string_data, make_clear_multibyte_string): Use it.
(pin_string): New.
* src/pdumper.c (dump_string): Fix incorrect comment.
Update hash for Lisp_String (only comments changed, not contents).
* src/lread.c (read1):
* src/alloc.c (Fmake_byte_code, purecopy):
* src/bytecode.c (Fbyte_code): Pin bytecode on object creation.
(exec_byte_code): Don't copy bytecode. Retain `bytestr` explicitly.
* src/lisp.h (Lisp_String): Explain special size_byte values.
(string_immovable_p): New.
