Functions on `completion-at-point-functions` should not modify
the buffer. Pcomplete itself mostly abides by this but Eshell's
use of it doesn't. Try and catch those cases. Also fix one of
those cases.
* lisp/pcomplete.el (pcomplete-allow-modifications): New var.
(pcomplete-completions-at-point): Enforce it.
(pcomplete, pcomplete-expand-and-complete, pcomplete-expand):
Rebind it since these commands expect the extra side effects.
* lisp/eshell/em-cmpl.el (eshell--pcomplete-insert-tab): New function,
extracted from `eshell-complete-parse-arguments`.
(eshell-complete-parse-arguments): Use it and obey
`pcomplete-allow-modifications`.
Use the new number-to-string code to speed up fixnum printing, with
similar results (often more than twice as fast as before).
* src/data.c (Fnumber_to_string): Move fixnum conversion to...
(fixnum_to_string): ... this new function.
* src/lisp.h: (fixnum_to_string): External declaration.
* src/print.c (print_object): Use fixnum_to_string instead of sprintf.
Do the binary-to-decimal conversion by hand for fixnums instead of
calling sprintf. This results in a noticeable speed increase (on my
machine, 2.2× faster excluding GC).
* src/data.c (Fnumber_to_string): Don't use sprintf for fixnums.
* etc/NEWS: Announce new user option `dired-mouse-drag-files'.
* lisp/dired.el (dired-mouse-drag-files): New user option.
(dired-mouse-drag): New command.
(dired-mouse-drag-files-map): New variable.
(dired-insert-set-properties): Add additional keymap if mouse
dragging is enabled.
* lisp/select.el (xselect-convert-to-targets): Handle new
form of selection converters.
(xselect-convert-to-username):
(xselect-convert-to-text-uri-list):
(xselect-uri-list-available-p): New functions.
(selection-converter-alist): Add them as selection converters.
* src/xselect.c (x_get_local_selection): Handle new form of
selection converters.
(syms_of_xselect): Update doc strings.
The dependencies between `advice`, cl-generic`, `bytecomp`, `cl-lib`,
`simple`, `help`, ... were becoming unmanageable.
Break the reliance on `advice` (which includes making sure the
compiler is not needed during the early bootstrap).
* lisp/simple.el (pre-redisplay-function): Set without using `add-function`.
* lisp/loadup.el (advice, simple): Move to after `cl-generic`.
* lisp/help.el (command-error-function): Set without using `add-function`.
(help-command-error-confusable-suggestions): Explicitly call
`command-error-default-function` instead.
* lisp/emacs-lisp/cl-macs.el (pcase--mutually-exclusive-p): Don't
optimize during early-bootstrap.
* lisp/emacs-lisp/cl-generic.el (cl--generic-lambda): Tiny simplification.
(cl-defmethod): Label the obsolescence warning as it should.
(cl--generic-compiler): New variable.
(cl--generic-get-dispatcher): Use it.
(cl--generic-prefill-dispatchers): Make freshly made dispatchers.
Using a plain C struct instead of type-punning Lisp_Object stack slots
makes the bytecode interpreter code more type-safe and potentially
faster (from better alias analysis), and the special-purpose accessors
are no longer needed. It also reduces the stack requirements when
using 64-bit Lisp_Object on 32-bit platforms.
* src/bytecode.c (enum stack_frame_index)
(sf_get_ptr, sf_set_ptr, sf_get_lisp_ptr, sf_set_lisp_ptr,
sf_get_saved_pc, sf_set_saved_pc): Remove.
(BC_STACK_SIZE): Now in bytes, not Lisp words.
(struct bc_frame): New.
(init_bc_thread, mark_bytecode, Finternal_stack_stats, valid_sp)
(exec_byte_code):
* src/lisp.h (struct handler, get_act_rec, set_act_rec):
Adapt to new struct bc_frame.
* lisp/net/tramp.el (tramp-file-name): Add ;;;###tramp-autoload
cookie. (Bug#50869)
* test/lisp/net/tramp-tests.el (tramp-test47-unload): Do not skip.
Test reload.
* src/xterm.c (x_dnd_begin_drag_and_drop): Error out if f is
invisible. It makes no sense for an invisible frame to be a
drag source, so the function just hangs.
* src/haikufns.c (haiku_create_frame): Set configury_done and do
pending fullscreen change if any.
* src/haikuterm.c (haiku_fullscreen): Defer actually setting
fullscreen until configury_done is set.
* src/haikuterm.h (struct haiku_output): New field
`configury_done'.
* lisp/mouse.el (mouse-drag-and-drop-region-display-tooltip)
(mouse-drag-and-drop-region-hide-tooltip): New functions.
(mouse-drag-and-drop-region): Use them instead of calling
`x-hide-tip' and `x-show-tip' directly.
* src/haiku_support.cc (grab_view, grab_view_locker): New
variables.
(MouseMoved, MouseDown, MouseUp): Keep track of the grab and
don't deliver motion events to any other view.
* doc/lispref/frames.texi (Drag and Drop): Fix documentation of
`x-begin-drag' to match actual function arity.
* lisp/term/haiku-win.el (haiku-dnd-selection-value): New
variable.
(haiku-dnd-selection-converters): New variable.
(haiku-dnd-convert-string): New function.
(gui-backend-get-selection, gui-backend-set-selection): Handle
XdndSelection specially.
(x-begin-drag): New function.
* src/haiku_select.cc (be_create_simple_message)
(be_add_message_data): New functions.
* src/haiku_support.cc (WAIT_FOR_RELEASE): New message type.
(class EmacsView, MouseUp): If waiting for release, reply and
drop event.
(be_drag_message, be_drag_message_thread_entry): New functions.
* src/haiku_support.h: Update prototypes.
* src/haikuselect.c (lisp_to_type_code, haiku_lisp_to_message)
(Fhaiku_drag_message): New functions.
(syms_of_haikuselect): Define new subr.
* src/haikuselect.h: Update prototypes.
* src/bignum.c (get_random_limb, get_random_limb_lim)
(get_random_bignum): New functions, for more-efficient
generation of random bignums without using Frem etc.
* src/fns.c (get_random_fixnum): New function.
(Frandom): Use it, and get_random_bignum.
Be consistent about signalling nonpositive integer arguments;
since zero is invalid, Qnatnump is not quite right here.
* src/sysdep.c (get_random_ulong): New function.
This fixes bug #54079.
* lisp/emacs-lisp/bytecomp.el (byte-compile-initial-macro-environment): Change
the position of 'byte-run-strip-symbol-positions' in the eval-when-compile
entry. Add a call to `byte-run-strip-symbol-positions' in the
eval-and-compile entry.
There are custom entries that contain lambda's as values by default,
which can result in them containing embedded NULs after
byte-compilation, which wreaks havoc when they are saved to .emacs and
later read in. (Bug#52554)
* lisp/cus-edit.el (custom-save-all): Bind
print-escape-control-characters to t.
* lisp/startup.el (startup--load-user-init-file): Bind
inhibit-null-byte-detection to t.
The current error message is simply 'not running', but
'status_message' can give information about why the process is in that
state, such as network errors, so return that as well. (Bug#53762)
* src/process.c (send_process, Fprocess_send_eof): Add the output of
'status_message' to the error string.
