* 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.
Copyright-paperwork-exempt: yes
* doc/lispref/display.texi (Displaying Messages): Document
set-message-function and clear-message-function.
* lisp/minibuffer.el (minibuffer-message-clear-timeout): New defcustom.
(minibuffer-message-timer, minibuffer-message-overlay): New variables.
(set-minibuffer-message, clear-minibuffer-message): New functions.
(set-message-function, clear-message-function): Set variables to
set-minibuffer-message and clear-minibuffer-message respectively.
* src/keyboard.c (read_char): Call clear_message when
Vclear_message_function is a function.
* src/xdisp.c (set_message): Call Vset_message_function when it's a function.
(clear_message): Call Vclear_message_function when it's a function.
(syms_of_xdisp): New variables set-message-function and clear-message-function
(bug#38457).
* src/process.c (syms_of_process) <read-process-output-max>:
New variable.
(read_process_output): Use it instead of the hard-coded
constant 4096. (Bug#38561)
Use SAFE_ALLOCA to support large buffers for reading process
output.
* etc/NEWS: Mention 'read-process-output-max'.
* src/w32fns.c (setup_w32_kbdhook): Don't initialize
is_debugger_present here...
(globals_of_w32fns): ...initialize it here. Also initialize
the new global variable set_thread_description.
* src/systhread.c: [WINDOWSNT] Include mbctype.h
(w32_set_thread_name): New function.
(MS_VC_EXCEPTION): New macro.
(THREADNAME_INFO, IsDebuggerPresent_Proc)
(SetThreadDescription_Proc): New typedefs.
(w32_beginthread_wrapper): Call w32_set_thread_name to set the
name of the new thread.
* src/thread.h (struct thread_state): New member thread_name.
* src/thread.c (Fmake_thread): Set the thread_name field of
the new thread object.
(run_thread): Free the thread_name member after the thread
exits.
* src/xfaces.c (face_at_string_position): Revert the last
change, as it cannot possibly solve bug#38563.
* src/xdisp.c (face_at_pos): Fix a typo made during last
change here, which broke face merging for display strings.
(Bug#38633)
* doc/lispref/internals.texi (Garbage Collection)
(Pure Storage):
* src/alloc.c (Fgarbage_collect): Update the documentation of
pure-space overflow for when pdumper is used. (Bug#38492)
* src/emacs.c (Fdump_emacs): Remove stray closing brace that
breaks the build when configured with --with-dumping=unexec on
GNU/Linux. (Apparently everybody is using pdumper now.)
I introduced the bug in 2019-07-09T00:50:39Z!eggert@cs.ucla.edu.
