* src/xdisp.c (message_to_stderr): When running as a batch
process, the output from `message' goes to stderr, and has a
newline appended. Rewrite the code so that only one fwrite is
performed to enable messages that are shorter than PIPE_BUF
(usually 4096 on modern operating systems) are written out as one
chunk, as this will ensure that the messages are not interleaved
with messages from other processes that are writing at the same
time. This does not affect other stderr outputs, just the ones
from `message'.
* src/w32.c (w32_my_exename): New function.
* src/w32.h (w32_my_exename): Add prototype.
* src/emacs.c (load_pdump_find_executable) [WINDOWSNT]: Find
the actual file name of the program without looking along
PATH, by calling w32_my_exename.
* nt/mingw-cfg.site (ac_cv_func_canonicalize_file_name)
(ac_cv_func_realpath, gl_cv_func_realpath_works): Disable
testing.
* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_canonicalize-lgpl): Set
to true.
* admin/unidata/Makefile.in (maintainer-clean):
Instead of removing macuvs.h here ...
(extraclean): ... Remove it here.
* admin/unidata/uvs.el (uvs-print-table-ivd):
Add to comment explaining why macuvs.h is in Git.
* src/macuvs.h: Regenerate and re-add to Git.
* src/keyboard.c (parse_tool_bar_item): Add equivalent key binding to
the tooltip string of toolbar buttons.
* etc/NEWS: Announce it.
* etc/TODO: Remove its entry. (Bug#36156)
* src/fileio.c (Fexpand_file_name): Fix off-by-one error in an
assertion. This avoids assertion violations when the home
directory is an empty string for some reason. (Bug#36363)
It can be generated automatically and easily during a normal
bootstrap, so there’s no need to keep it in the repository.
* admin/unidata/Makefile.in (maintainer-clean):
Behave like extraclean and remove macuvs.h etc.
* src/macuvs.h: Remove.
* src/Makefile.in (extraclean): Remove TAGS and config.in.
* Makefile.in (extraclean): Remove info, configure and
emacsver.texi in extraclean.
* admin/unidata/Makefile.in (extraclean): Make it depend on
distclean to remove .elc files.
* leim/Makefile.in (extraclean): Depend on bootstrap-clean to
remove generated .el files.
* lib/Makefile.in (extraclean): Added target to remove sys
directory and run distclean.
* lisp/Makefile.in (extraclean): Also remove loaddefs*.el~ files.
* src/gmalloc.c (mabort) [GC_MCHECK && !__GNU_LIBRARY__]:
* src/term.c (vfatal): Remove fflush (stderr) when it is now a
no-op because newline automatically flushes stderr.
* font.c (font_put_extra): If VAL is Qunbound, delete the slot for PROP from
the list of extra properties. Previous value Qnil is valid as boolean.
(font_clear_prop): Changed argument of font_put_extra for property removal.
* src/w32font.c (syms_of_w32font): Don't make the Uniscribe
font backend "superceded" here, ...
* src/w32uniscribe.c (syms_of_w32uniscribe_for_pdumper):
... make it "superceded" here, only if the HarfBuzz DLL was
successfully loaded. This is because Emacs compiled with
HarfBuzz support might run on a system without the DLL.
* src/w32fns.c (Fx_create_frame, w32_create_tip_frame):
Register the HarfBuzz font backend only if it is available.
* src/Makefile.in (AM_V_NO_PD): New macro written by Andreas
Schwab that can be either --no-print-directory or "".
(%.elc): Use it instead if the if statement.
* src/pdumper.c (dump_cons, dump_interval_tree, dump_string)
(dump_marker, dump_overlay, dump_finalizer)
(dump_bignum, dump_float, dump_fwd_int, dump_fwd_bool)
(dump_fwd_obj, dump_fwd_buffer_obj, dump_fwd_kboard_obj)
(dump_fwd, dump_blv, dump_symbol, dump_vectorlike_generic)
(dump_hash_table, dump_buffer, dump_bool_vector, dump_subr)
(dump_vectorlike, dump_object, dump_charset) [CHECK_STRUCTS]:
Make the error message more specific where to find the comment
to CHECK_STRUCTS.
* src/Makefile.in (%.elc): Default to not printing the
entering/leaving lines when compiling .el files in the second
stage of bootstrapping Emacs. V=1 will output them.
* src/xterm.c (x_scroll_run) [USE_CAIRO]: Use FRAME_CR_CONTEXT or surface type
for conditions to call XCopyArea rather than FRAME_X_DOUBLE_BUFFERED_P.
Set compositing operator to CAIRO_OPERATOR_SOURCE when copying image.
* src/hbfont.c (hbfont_shape): Fix setting TO of lglyph for
the case when Lisp shape-gstring function performed some
compositions by itself. This happens with hebrew.el. See
https://lists.freedesktop.org/archives/harfbuzz/2019-June/007396.html
for the details of the problem this solves.
* src/xdisp.c (compute_stop_pos): Set the limit for searching
for changes in text properties such that the limit is never in
the middle of composable text. (Bug#28312)
