Fixes Bug#39363.
* configure.ac: Add check for 3-argument version of
pthread_setname_np.
* src/systhread.c (sys_thread_set_name)
[HAVE_PTHREAD_SETNAME_NP_3ARG]: Call pthread_setname_np with
3 arguments.
* src/minibuf.c (read_minibuf): Parse input string after saving
the string to the history list instead of before, in case parsing
signals an error or is interrupted by C-g. (Bug#39291)
Now, functions such as call-proess-region invoke after-change-functions
correctly.
* src/callproc.c (call_process): Call prepare_to_modify_buffer in a single
place, no longer delegating the task to insert_1_both, etc. Call
signal_after_change in each of two code branches, such that
before-change-functions and after-change-functions are always called in
balanced pairs.
* src/xdisp.c (try_window_reusing_current_matrix, try_window_id):
* src/dispnew.c (scrolling_window) [HAVE_NTGUI]: If
w32-use-visible-system-caret is non-nil, disallow scrolling the
display are in scroll_run_hook. This avoids copying traces of the
caret, about which Emacs knows nothing, and thus considers those
pixels show the default background. (Bug#39188)
(gui_update_window_end): Block input only around part of the code,
as we did before this code was extracted from backend-specific
implementations.
* src/w32term.c (w32_update_window_begin, w32_update_window_end):
Only hide/show the caret when redisplaying the window where the
caret is shown.
* src/term.c (handle_one_term_event): Call tty_handle_tab_bar_click.
* src/xdisp.c (tty_handle_tab_bar_click): Force reset of up_modifier bit
from the event modifiers.
* lisp/tab-line.el (tab-line-tab-current): No need to use inverse-video
on console/xterm because the selected tab already uses inverse-video.
* src/systhread.c (sys_thread_create) [!THREADS_ENABLED]: Update
the function's signature to match prototype. Reported by Glenn
Morris <rgm@gnu.org>. (Bug#38632)
pthread_setname_np takes only a single argument on BSD and macOS,
and affects the current thread only.
* configure.ac: Add check for single-argument pthread_setname_np
* src/systhread.c (sys_thread_set_name): New (w32 and pthread versions).
(sys_thread_create): Remove name argument and name-setting.
(w32_beginthread_wrapper): Remove name-setting.
* src/systhread.h (sys_thread_create, sys_thread_set_name):
Update prototypes.
* src/thread.c (run_thread): Call sys_thread_set_name.
(Fmake_thread): Adapt call to sys_thread_create.
* src/thread.h (struct thread_state): Adjust comment.
When using multiple monitors, and HiDPI, the top-left coordinates of
the monitors need to be adjusted, not just the width and height
(Bug#31223).
* xfns.c (Fx_display_monitor_attributes_list): Scale top-left
coordinates.
* src/xdisp.c (try_cursor_movement, redisplay_window)
(row_containing_pos): Skip tab-line glyph rows in addition to
header-line rows, when working on the top-most glyph row of a
window. This avoids assertion violations in set_cursor_from_row.
(Bug#38966)
* configure.ac: Remove check for sys/prctl.h and prctl, check for
pthread_setname_np instead.
* systhread.c: Remove sys/prctl.h include.
(sys_thread_create) [HAVE_PTHREAD_SETNAME_NP]: Use pthread_setname_np
to set the name of the newly created thread (Bug#38632).
* thread.c (Fmake_thread): Use ENCODE_SYSTEM instead of
ENCODE_UTF_8 on the thread name.
* lisp/frame.el (top-level): Add mode-line-format,
tab-line-format, and header-line-format to the list of variables
that should trigger an immediate redisplay of the buffer's
window. This fixes redisplay of windows when the mode line
changes its height.
* src/xdisp.c (window_box_height): Use the window's
mode_line_height, tab_line_height, and header_line_height fields
in preference to CURRENT_MODE_LINE_HEIGHT,
CURRENT_TAB_LINE_HEIGHT, and CURRENT_HEADER_LINE_HEIGHT,
respectively. This fixes display of vertical scroll bar when the
height of the window's mode line changes.
* src/dispnew.c (adjust_glyph_matrix): When resizing a window's
matrix, reset the mode_line_p flag of the previous mode-line row,
so that the window_box_height, CURRENT_MODE_LINE_HEIGHT, and their
ilk won't use stale info. (Bug#38828)
* src/xfns.c (x_get_net_workarea): Change a recently moved #ifndef
so that GTK builds which need this function will compile it.
Reported by John <jpff@codemist.co.uk>.
(cherry picked from commit d36adb544d)
Occasionally, loading cl-generic.el from source requires
max_specpdl_size > 1600 when bootstrapping, and thus fails.
In any case we are very close to the limit.
* src/eval.c (init_eval_once): Raise max_specpdl_size to 1800.
* doc/lispref/variables.texi (Local Variables): Update docs.
This improves on 2019-12-25T20:01:07Z!eggert@cs.ucla.edu,
by fixing a GCC warning on Ubuntu 18.04.3
“‘x_get_net_workarea’ defined but not used”.
* src/xfns.c (x_get_net_workarea) [!USE_GTK]: Do not define.
* src/window.c (grow_mini_window): Fix resizing of mini-window
when the echo area is cleared, and the caller asks for the
mini-window to have zero lines. (Bug#38791)
* etc/NEWS: Announce change to matching color fonts when using XFT.
* src/ftfont.c (ftfont_list) [HAVE_XFT && FC_COLOR]: Query for the
color attribute of the matched font, and skip it if it is not
FcFalse (Bug#37786).
* src/xfns.c (x_get_net_workarea) [!HAVE_GTK3]:
Define in this case too, since x_get_monitor_attributes_fallback
contains a call to it regardless whether HAVE_GTK3 is defined.
* src/coding.c (Fencode_coding_region): Clarify what this does.
(Fdecode_coding_region): Ditto.
* src/fns.c (Fbase64_decode_region): Clarify that this function
returns bytes, not text (bug#38587).
(Fbase64_encode_region): Clarify that this function takes bytes,
not text.
* src/image.c (imagemagick_initialize): New function,
with body taken from imagemagick_load_image.
(imagemagick_load_image, Fimagemagick_types): Use it.

This is a useful property when doing further bit-twiddling with the
magnitude array before/after calling extract_big_integer or
make_big_integer. For example, constructing an emacs_limb_t object
using repeated shift-and-add should work as expected, but relies on
the type not having padding bits. Since the C standard already
guarantees that unsigned integers use a pure binary representation,
not having padding bits is enough to guarantee that the type has
unique object representations in the sense of C++’s
std::has_unique_object_representations.
* doc/lispref/internals.texi (Module Values): Document that
emacs_limb_t doesn’t have padding bits.
* src/emacs-module.c: Verify that emacs_limb_t doesn’t have padding
bits.
* src/xdisp.c (extend_face_to_end_of_line): Don't return early
if face attributes beyond background color and box are set,
since that means these attributes need to be extended past the
EOL.
* lisp/term/ns-win.el (ns-insert-working-text):
(ns-delete-working-text): Change how working text is deleted to handle
changed order of operations.
* src/nsterm.m ([EmacsView insertText:]): Move deletion of working
text until after insertion of new text.
