Backport from master.
* src/bytecode.c (exec_byte_code): Save VECTOR into stack slot
so that it survives GC. The stack slot was otherwise unused,
so this doesn’t cost us memory, only a store insn.
* src/nsterm.m (ns_clip_to_rect):
(ns_reset_clipping): Remove gsaved variable and associated code.
(ns_flush_display): Remove function.
(ns_copy_bits): use translateRectsNeedingDisplayInRect:by: to copy any
pending drawing actions along with the image.
([EmacsView windowWillResize:toSize:]): Remove unneeded call.
([EmacsView drawRect:]): Remove redundant call to ns_clear_frame_area,
and optimize the exposed rectangles.
(ns_draw_window_cursor): Remove unneeded disabling of screen updates.
* doc/lispref/windows.texi (vertical scrolling): Clarify the meaning of
vertical scrolling by referring to tall screen lines, images, and the display
action. Clarify an ambiguous English tense.
* src/window.c (window-vscroll, set-window-vscroll): Amend doc strings to
refer to display.
* src/conf_post.h (bool_bf): Use 'unsigned int' in the MinGW
builds. Suggested by Tom Tromey <tom@tromey.com>. (Bug#33017)
* src/dispnew.c (scrolling_window): Update commentary
regarding xwidget builds.
* src/xdisp.c (get_phys_cursor_geometry): Treat rows at and
beyond ZV specially. Don't let the cursor exceed the
vertical dimensions of the row.
(maybe_produce_line_number): Use the 'line-number' face
instead of 'default' for blank fields beyond ZV. Don't update
the IT metrics when displaying blank line-number fields beyond
ZV. (Bug#32337)
Backport from master.
* src/scroll.c (struct matrix_elt): Change unsigned char fields to
int to handle frames with more than 255 lines (Bug#32951).
Copyright-paperwork-exempt: yes
* src/eval.c (Fsignal): If both arguments are nil, replace the
first one with 'error', to avoid assertion violations further
down the line. (Bug#32961)
* src/minibuf.c (syms_of_minibuf) <Vread_hide_char>: Clarify
documentation and mention where else the variable is used.
* doc/lispref/minibuf.texi (Reading a Password): Add an index
entry for 'read-hide-char'.
* src/keyboard.c (kbd_buffer_store_buffered_event): Support
also the internal buffer-switch events.
(syms_of_keyboard) <Qbuffer_switch>: New DEFSYM.
* lisp/subr.el (while-no-input-ignore-events): Ignore
'buffer-switch' events. Reported by Michael Heerdegen
<michael_heerdegen@web.de>.
* etc/NEWS: Mention the change in behavior of 'while-no-input'
* src/term.c (init_tty): Call delete_terminal_internal if emacs_open
fail.
* src/terminal.c (delete_terminal): Move some code into
delete_terminal_internal and call it.
(delete_terminal_internal): New function.
* src/termhooks.h: Prototype for delete_terminal_internal.
See bug#31904 and bug#32812.
* src/nsterm.m (ns_update_begin): Don't lock focus, only clip if there
is already a view focused.
(ns_update_end): Don't mess with view focusing any more.
(ns_focus): Only clip drawing if there is already a focused view,
otherwise mark area dirty for later drawing. Renamed ns_clip_to_rect.
All callers changed.
(ns_unfocus): Don't unfocus the view any more. Renamed
ns_reset_clipping. All callers changed.
(ns_clip_to_row): Update to match ns_clip_to_rect.
(ns_clear_frame):
(ns_clear_frame_area):
(ns_draw_fringe_bitmap):
(ns_draw_window_cursor):
(ns_draw_vertical_window_border):
(ns_draw_window_divider):
(ns_dumpglyphs_stretch):
(ns_draw_glyph_string): Only draw if ns_focus or ns_clip_to_row
return YES.
(ns_copy_bits): Remove superfluous calls to ns_(un)focus.
(ns_flush_display): New function.
* src/keymap.c (Ftext_char_description):
* doc/lispref/help.texi (Describing Characters): More accurate
description of 'text-char-description'. Remove incorrect
examples from the ELisp manual. (Bug#32743)
* src/gnutls.c (gnutls_cipher_get_tag_size): Make it return
zero only for versions of GnuTLS < 3.2.2, where
gnutls_cipher_get_tag_size was introduced. This fixes the
GnuTLS test suite, which assumes that any cipher whose tag
size is non-zero is AEAD-capable, and doesn't test such ciphers
if AEAD is not available, i.e. for GnuTLS < 3.5.1. (Bug#32446)
We previously used functions available only in 3.2+ for all 3.x
versions.
* src/gnutls.c [GNUTLS_VERSION_NUMBER < 0x030501]: Replace calls to
gnutls_cipher_get_tag_size with 0.
[GNUTLS_VERSION_NUMBER < 0x030200]: Alias gnutls_cipher_get_iv_size
to gnutls_cipher_get_block_size, gnutls_digest_list to
gnutls_mac_list, and gnutls_digest_get_name to gnutls_mac_get_name.
[WINDOWSNT]: Adjust DLL function definitions and declarations
accordingly.
* test/src/buffer-tests.el
(overlay-modification-hooks-deleted-overlay): New test.
* src/buffer.c (report_overlay_modification): Don't bypass all
the overlay-modification hooks; instead, invoke each function
only if the buffer associated with the overlay is the current
buffer. (Bug#30823)
* doc/lispref/help.texi (Describing Characters):
* doc/lispref/commands.texi (Keyboard Events)
(Reading One Event, Classifying Events): Make the distinction
between characters and character events more explicit.
* src/keymap.c (Ftext_char_description)
(Fsingle_key_description):
* src/lread.c (Fread_char, Fread_char_exclusive): Doc fixes,
to make a clear distinction between a character input event
and a character code. (Bug#32562)
* doc/lispref/threads.texi (Basic Thread Functions): Use thread-live-p.
* etc/NEWS: 'thread-alive-p' has been renamed to 'thread-live-p'.
* src/thread.c (thread_live_p): Rename from thread_alive_p. Adapt
all callees.
(Fthread_live_p): Rename from Fthread_alive_p.
(syms_of_threads): Make thread-alive-p an alias of thread-live-p.
* test/src/thread-tests.el (all): Replace `thread-alive-p' by
`thread-live-p'.
(threads-live): Rename from `threads-alive'.
* src/emacs-module.c (module_free_global_ref): Compare a value to be
freed with all entries of the list.
* test/data/emacs-module/mod-test.c (Fmod_test_globref_free): New
function.
(emacs_module_init): Make it accessible from Lisp.
* test/src/emacs-module-tests.el (mod-test-globref-free-test): New
test which uses it.
* src/w32console.c <glyph_base>: Reduce the number of elements
to 80.
<glyphs, glyphs_len>: New static variables.
(w32con_clear_end_of_line): If the line is wider than the
current size of the "empty row" in 'glyphs', reallocate
'glyphs' to support the full width of the frame. This
avoids segfaults when the frame is wider than 256 columns.
(Bug#32445)
Problem reported by Eli Zaretskii in:
https://lists.gnu.org/r/emacs-devel/2018-08/msg00380.html
* src/data.c (arithcompare): Work around incompatibility
between gcc -fexcess-precision=fast and the C standard on x86,
by capturing the results of floating-point comparisons before
the excess precision spontaneously decays. Although this fix
might not work in general, it does work here and is probably
good enough for the platforms we care about.
(cherry picked from commit a84cef9095)
* src/editfns.c (styled_format): Add the spec beginning index
to the info recorded for each format spec, and use it to
detect the case that a format spec and its text property end
where the next spec with another property begins. (Bug#32404)
* test/src/editfns-tests.el (format-properties): Add tests for
bug#32404.
* src/fileio.c (get_file_errno_data): Refactor out into its own
function so that we can reuse the error handling from an async
context (bug#31901).
* src/process.c (connect_network_socket): When an async :family
'local client fails (with a file error, for instance), mark the
process as failed.
(cherry picked from commit 92ba34d89a)
* src/xdisp.c (redisplay_window): Make sure desired_matrix is
cleared before calling try_window. This is important when
display-line-numbers is non-nil, because line-number display code
assumes each glyph row is completely cleared when it is called to
produce a line number. (Bug#32358)
* src/textprop.c (set_text_properties): If the call to
modify_text_properties modifies the interval tree as side effect,
recalculate the correct interval for START and END. (Bug#32265)
* src/editfns.c (Freplace_buffer_contents): Call the modification
hooks on the entire region where replacements could have taken
place. The previous attempts of being more accurate just
introduced bugs. (Bug#32278)
* src/keyboard.c (syms_of_keyboard) <debug-on-event>
<attempt-stack-overflow-recovery>
<attempt-orderly-shutdown-on-fatal-signal>: Make sure the first
sentence of the doc string fits on a single line.
* src/gnutls.c (Fgnutls_hash_digest, gnutls_symmetric)
(Fgnutls_hash_mac): Check CONSP before invoking XCDR. (Bug#32187)
Report values of invalid arguments when signaling an error.
