* src/thread.c (mark_one_thread): Use NILP to compare with
m_saved_last_thing_searched, which is a Lisp object. Reported by
Andreas Politz <politza@hochschule-trier.de>.
* src/thread.h <int select_func>: Make the 5th and 6th arguments
be 'const'.
* src/process.c [WINDOWSNT]:
* src/w32proc.c: Make the 5th and 6th argument to sys_select be
'const'.
* src/eval.c (do_specbind): Don't require a "symbol" that is
actually a cons cell, in order to call set-default, as there are
no longer such bindings. This makes do_specbind work like the
pre-concurrency implementation in specbind for bindings of
forwarded symbols. Use specpdl_kind to access the type of the
binding.
(specpdl_kind): New function.
This is needed if ‘read’ is called soon after startup, before the
Unicode tables have been set up, and it reads a \N escape and
needs to look up a value the Unicode tables, a lookup that in turn
calls read1 recursively. Although this change doesn’t make ‘read’
fully reentrant, it’s good enough to handle this case.
* src/lread.c (read_buffer_size, read_buffer): Remove static vars.
(grow_read_buffer): Revamp to use locals, not statics, and to
record memory allocation un the specpdl. All callers changed.
(read1): Start with a stack-based buffer, and use the heap
only if the stack buffer is too small. Use unbind_to to
free any heap buffer allocated. Use bool for boolean.
Redo symbol loop so that only one call to grow_read_buffer
is needed.
(init_obarray): Remove no-longer-needed initialization.
* src/Makefile.in (NON_OBJC_CFLAGS): New macro.
(ALL_OBJC_CFLAGS): Use it.
(EMACS_CFLAGS): New macro, with most of the old ALL_CFLAGS.
(ALL_CFLAGS, ALL_OBJC_FLAGS): Use it.
* src/bytecode.c (exec_byte_code):
* src/image.c (parse_image_spec):
Prefer FUNCTIONP (x) to !NILP (Ffunctionp (x)).
* src/eval.c (FUNCTIONP): Move here ...
* src/lisp.h: ... from here. No longer inline, as that
bloats the text and does not help speed (at least on my platform).
(functionp): Remove this name, since callers use FUNCTIONP.
For hashtable entries with symbol keys, `test-completion' would convert
the key to a string before calling PREDICATE, unlike `try-completion'
and `all-completions'.
* src/minibuf.c (Ftest_completion): Pass original key from hashtable.
Since 2016-06-26 "Fix test-completion with completion-regexp-list", when
calling test-completion with an alist collection, the predicate was
recieving the string value instead of the alist entry (Bug#24966).
* src/minibuf.c (Ftest_completion): Don't modify the found element, just
test STRING against `completion-regexp-list'.
* test/src/minibuf-tests.el: New tests for `try-completion',
`all-completions', and `test-completion'.
This is a bit clearer than _Noreturn functions that (do not)
return a non-void type.
* src/callproc.c (call_process) [MSDOS]:
Use 'status' local to record status.
(child_setup): Return CHILD_SETUP_TYPE.
* src/data.c, src/lisp.h (wrong_type_argument): Return void.
All callers changed.
* src/lisp.h (CHILD_SETUP_TYPE): New macro.
This replaces looking up the variable name in redisplay--variables when
setting it.
* lisp/frame.el: Replace redisplay--variables with add-variable-watcher
calls.
* src/xdisp.c (Fset_buffer_redisplay): Rename from maybe_set_redisplay,
set the redisplay flag unconditionally.
(Vredisplay__variables): Remove it.
* src/data.c (set_internal): Remove maybe_set_redisplay call.
* src/image.c (imagemagick_load_image): Set wand size before loading
blob when ':width' and ':height' are provided.
* lisp/image.el (image-format-suffixes): Add 'image/x-rgb'.
This simplifies the code a bit, and makes the structs more
shareable and less likely to become corrupt.
* src/alloc.c (cleanup_vector):
* src/font.c (valid_font_driver, font_prepare_cache)
(font_finish_cache, font_get_cache, font_clear_cache)
(register_font_driver, font_update_drivers):
* src/font.h (struct font, struct font_driver_list)
(valid_font_driver):
struct font_drivers are now const.
* src/font.c, src/ftcrfont.c, src/ftfont.c, src/nsfont.m, src/xfont.c:
Omit no-longer-necessary decls.
* src/ftcrfont.c (syms_of_ftcrfont):
* src/ftxfont.c (syms_of_ftxfont):
* src/xftfont.c (syms_of_xftfont):
Omit no-longer-necessary initialization code.
* src/ftcrfont.c (ftcrfont_driver):
* src/ftfont.c (ftfont_driver):
* src/ftxfont.c (ftxfont_driver):
* src/macfont.m (macfont_driver):
* src/nsfont.m (nsfont_driver):
* src/xfont.c (xfont_driver):
* src/xftfont.c (xftfont_driver):
Use C99-style initializer for ease of maintenance, and make it const.
* src/ftcrfont.c, src/ftxfont.c, src/xftfont.c:
Refer to functions like ftfont_text_extents directly.
* src/ftfont.c (ftfont_get_cache, ftfont_list, ftfont_list_family)
(ftfont_has_char, ftfont_encode_char, ftfont_text_extents)
(ftfont_get_bitmap, ftfont_anchor_point, ftfont_otf_capability)
(ftfont_variation_glyphs, ftfont_filter_properties)
(ftfont_combining_capability):
* src/xfont.c (xfont_get_cache):
Now extern, so that other modules’ struct font_drivers can use
them directly.
* src/macfont.m (macfont_descriptor_entity):
* src/nsfont.m (nsfont_open):
Use constant directly; this is clearer.
* src/lisp.h (enum Lisp_Save_Type): Put SAVE_UNUSED,
SAVED_INTEGER, SAVE_FUNCPOINTER, SAVE_POINTER, and SAVE_OBJECT
into this enum rather than into an anonymous enum. This avoids
diagnostics from Sun C 5.14 and is a bit clearer anyway.
Since 2016-07-18 "Keep w32 environment settings internal only", the
upcasing of environment variables "Path" and "ComSpec" occured after
initializing process-environment. This meant that Lisp code trying to
override "PATH" environment had no effect (Bug #24956).
* src/w32.c (init_environment): Upcase the "Path" and "ComSpec" entries
in Vprocess_environment.
* src/w32.c (w32_init_file_name_codepage): New function, resets
file_name_codepage and w32_ansi_code_page to undo the values
recorded during dumping.
(codepage_for_filenames): Fix an embarrassing typo. Ignore the
cached value of file-name encoding if it is nil, i.e. not
initialized yet. Actually cache the last used file-name encoding
to avoid calling APIs when not necessary.
* src/w32.h (w32_init_file_name_codepage): Add prototype.
* src/w32term.c (syms_of_w32term): Set the value of
w32_unicode_filenames according to the OS version. This avoids
resetting it during startup, which then causes temacs to run with
the incorrect value.
* src/emacs.c (main): Call w32_init_file_name_codepage early
during the startup.
* src/fileio.c (Fexpand_file_name) [WINDOWSNT]: Update 'newdir'
after converting $HOME to a UTF-8 string, so that 'newdirlim' is
consistent with it. (Bug#25038)
* lisp/international/mule-cmds.el (set-locale-environment): Set
'default-file-name-coding-system' to the ANSI codepage even in
non-interactive sessions.
* lisp/files.el (directory-abbrev-alist, abbreviated-home-dir):
Doc fix.
(abbreviate-file-name): Decode 'abbreviated-home-dir' if it is a
unibyte string.
* doc/lispref/files.texi (Directory Names): Index
'directory-abbrev-alist'.
* lisp/subr.el (while-no-input-ignore-events): Use them instead.
* src/keyboard.c (kbd_buffer_store_buffered_event):
Use help-echo for HELP_EVENT, iconify-frame for ICONIFY_EVENT,
and make-frame-visible for DEICONIFY_EVENT.
(syms_of_keyboard): Remove unneeded symbols.
* src/keyboard.c (kbd_buffer_store_buffered_event):
Translate event to corresponding symbol from `while-no-input-ignore-events`
and check them with Fmemq.
(syms_of_keyboard): Declare new lisp variable `while-no-input-ignore-events`
and its symbols.
* lisp/subr.el (while-no-input-ignore-events): Add default values.
* doc/lispref/commands.texi (Event Input Misc):
Document while-no-input-ignore-events.
* etc/NEWS: Same.
