They already did return their argument under some circumstances;
this change broadens it to further reduce allocation in common cases
(bug#40407).
* src/coding.c (convert_string_nocopy): New function.
(decode_file_name, encode_file_name): Use convert_string_nocopy.
* src/coding.h (ENCODE_FILE, DECODE_FILE): Note the nocopy semantics.
|
|
Run "TZ=UTC0 admin/update-copyright $(git ls-files)".
|
|
* src/coding.c (get_char_bytes, encode_string_utf_8)
(decode_string_utf_8): Fix commentary.
(encode_string_utf_8): Return the original ASCII string only
if NOCOPY is non-zero.
(decode_string_utf_8): Accept 2 additional arguments STR and
STR_LEN, which allow to pass the input text as a C string.
(make_string_from_utf8): Delegate the job to decode_string_utf_8.
* src/coding.h: Update the prototype of decode_string_utf_8.
* src/json.c (json_encode): Call encode_string_utf_8.
|
|
This partially reverts the changes in "extern function cleanup".
* src/coding.c (encode_string_utf_8, decode_string_utf_8): Now
extern again. They should NOT be static, as they are intended
to be used by the likes of json.c, where we need
highly-optimized code for processing UTF-8 strings. E.g.,
decode_string_utf_8 beats make_string_from_utf8 by a factor of
2 to 5 in a large number of scenarios.
|
|
Most of these functions can be static. A few are unused.
* src/coding.c (encode_string_utf_8, decode_string_utf_8):
Define only if ENABLE_UTF_8_CONVERTER_TEST, as they're
not needed otherwise.
* src/coding.c (encode_string_utf_8, decode_string_utf_8):
* src/data.c (integer_mod):
* src/fns.c (base64_encode_region_1, base64_encode_string_1):
* src/ftfont.c (ftfont_get_fc_charset):
Now static.
* src/sysdep.c (verrprintf): Remove; unused.
|
|
* src/coding.c (encode_string_utf_8, decode_string_utf_8): New functions.
* src/coding.h (encode_string_utf_8, decode_string_utf_8): Extern them.
|
|
* src/json.c (Fjson_insert):
* src/fileio.c (Finsert_file_contents):
* src/coding.h (decode_coding_gap): Adjust accordingly.
|
|
* src/coding.h (build_string_from_utf8): Rename from
build_utf8_string. All callers changed.
* src/coding.c (make_string_from_utf8): Rename from
make_utf8_string. All callers changed.
|

json_make_string and json_build_string are generally useful and not
JSON-specific. Move them to coding.[ch].
* src/coding.h (build_utf8_string): Move from json.c.
* src/coding.c (make_utf8_string): Move from json.c.
* src/json.c (json_make_string, json_build_string): Move to
coding.[ch]. Split out JSON-specific comment.
(json_parse_error, Fjson_serialize, json_to_lisp): Fix callers.
* src/emacs-module.c (module_make_function, module_make_string): Use
new functions.
(module_decode, module_decode_copy): Remove.

Note: portions of this change were mistakenly pushed as part
of an unrelated commit a35a1f6a9.
* src/buffer.c (Fget_buffer_create): Set inhibit_buffer_hooks
non-zero for temporary buffers created by coding.c. Don't run
buffer-list-update-hook for such buffers.
(Frename_buffer, Fkill_buffer, record_buffer)
(Fbury_buffer_internal): Don't run hooks for buffers whose
inhibit_buffer_hooks flag is set.
* src/buffer.h (struct buffer): New member
inhibit_buffer_hooks.
* src/pdumper.c (dump_buffer): Dump the new field. Update the
hash value in HASH_buffer_XXX.
* src/coding.c (make_conversion_work_buffer): Function deleted;
code moved to code_conversion_save.
(code_conversion_save): Insert code from
make_conversion_work_buffer, but arrange for unwind-protecting
the current buffer before switching to the work buffer. This
avoids leaving reused_workbuf_in_use set if user presses C-g
during encoding/decoding.
(Vcode_conversion_workbuf_name): Now external variable.
* src/coding.h (Vcode_conversion_reused_workbuf): Declare.
|
|
* lisp/subr.el (inhibit-null-byte-detection): Make it an obsolete alias.
* src/coding.c (setup_coding_system): Use new name.
(detect_coding): Rename null_byte_found => nul_byte_found.
(detect_coding_system): Use new name.
Rename null_byte_found => nul_byte_found.
(Fdefine_coding_system_internal): Use new name.
(syms_of_coding): Rename inhibit-null-byte-detection to
inhibit-nul-byte-detection.
* src/w16select.c (get_clipboard_data): null_char => nul_char.
* src/json.c (check_string_without_embedded_nuls): Rename from
check_string_without_embedded_nulls.
(Fjson_parse_string): Adjust accordingly.
* src/coding.h (enum define_coding_undecided_arg_index)
(enum coding_attr_index): ...null_byte... => ...nul_byte....

* lisp/international/mule.el (define-coding-system):
* lisp/vc/vc-git.el (vc-git--call):
* doc/lispref/nonascii.texi (Lisp and Coding Systems): Use the new name.

* src/charset.c, src/coding.c, src/coding.h, src/gmalloc.c:
* src/ralloc.c, src/regex-emacs.c: Simplify slightly by
assuming that ‘emacs’ is defined. These modules have long
been specific to Emacs, and are not used elsewhere.
|
|
* src/coding.h: Add INLINE_HEADER_BEGIN..INLINE_HEADER_END, since
this header now has an extern INLINE function.
|
|
* src/coding.h (UTF_16_HIGH_SURROGATE_P, UTF_16_LOW_SURROGATE_P): Move
from coding.c and document.
(surrogates_to_codepoint): New function.
* src/nsterm.m (insertText:): Properly handle surrogate pairs.

(lisp_to_json_toplevel_1, lisp_to_json): Use it. To save a bit of
time, check for invalid UTF-8 strings only after encountering an
error, since Jansson already rejects them.
* test/src/json-tests.el (json-serialize/invalid-unicode): Adapt
expected error symbol.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

* src/coding.c (encode_coding_utf_8): Now extern.
* src/terminal.c (terminal_glyph_code) [HAVE_STRUCT_UNIPAIR_UNICODE]:
Check for UTF-8, not just for multibyte.

* src/coding.h (enum coding_system_type, enum end_of_line_type):
Remove; unused.

* src/buffer.c, src/emacs.c, src/lread.c: Don’t include coding.h;
no longer needed, now that emacs_strerror is declared by lisp.h.
* src/coding.c (emacs_strerror): Remove; moved to emacs.c.
* src/coding.h (emacs_strerror) [emacs]: Remove decl; moved
to lisp.h.
* src/emacs.c (emacs_strerror): Move here from coding.c. Do not
convert result string; this is now the caller’s responsibility,
as some need conversion and others don’t.
* src/fileio.c (report_file_errno, report_file_notify_error):
Use emacs_strerror rather than rolling it ourselves.
* src/lisp.h (emacs_strerror): Move decl here from coding.h.
* src/lread.c (dir_warning): Just call emacs_strerror rather than
both strerror and emacs_strerror. Convert its result from
locale-coding-system, since it no longer does that conversion.
* src/sound.c (sound_perror):
* src/sysdep.c (emacs_perror, str_collate):
Use emacs_strerror, not strerror.

Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.

Redo src/*.h so that each include file is idempotent (that is, can
be included multiple times with the latter inclusions having no
effect) and standalone (that is, can be included by itself,
with no include file other than config.h needed as a prerequisite).
This is standard practice in GNU programs nowadays.

Fixes Bug#15880.
This patch also makes Q constants (e.g., Qnil) constant addresses
from the C point of view.
* make-docfile.c: Revamp to generate table of symbols, too.
Include <stdbool.h>.
(xstrdup): New function.
(main): Don't process the same file twice.
(SYMBOL): New constant in enum global_type.
(struct symbol): Turn 'value' member into a union, either v.value
for int or v.svalue for string. All uses changed.
(add_global): New arg svalue, which overrides value, so that globals
can have a string value.
(close_emacs_global): New arg num_symbols; all uses changed.
Output lispsym decl.
(write_globals): Output symbol globals too. Output more
ATTRIBUTE_CONST, now that Qnil etc. are C constants.
Output defsym_name table.
(scan_c_file): Move most of guts into ...
(scan_c_stream): ... new function. Scan for DEFSYMs and
record symbols found. Don't read past EOF if file doesn't
end in newline.

These names are now defined automatically by make-docfile.
* alloc.c (init_symbol): New function.
(Fmake_symbol): Use it.
(c_symbol_p): New function.

Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and
Lisp_Object *, since Qfoo is no longer an object whose address can be
taken. All uses changed.
* eval.c (run_hook): New function. Most uses of Frun_hooks changed to
use it, so that they no longer need to take the address of a Lisp sym.
(syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable.
* frame.c (syms_of_frame): Add defsyms for the frame_parms table.
* keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here.
DEFSYM Qdeactivate_mark before the corresponding var.
* keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line
instead of interning their symbols; this avoids duplicates.

New macros.
(LISP_INITIALLY_ZERO): Use it.
(enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol)
(EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*):

(DEFSYM): Now just a placeholder for make-docfile.
* lread.c (DEFINE_SYMBOLS): Define, for globals.h.
(intern_sym): New function, with body taken from old intern_driver.
(intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t.
All uses changed.
(define_symbol): New function.
(init_obarray): Define the C symbols taken from lispsym.
Use plain DEFSYM for Qt and Qnil.
* syntax.c (init_syntax_once): No need to worry about
Qchar_table_extra_slots.

src/xdisp.c (message3_nolog, message_with_string): Encode the string
before writing it to the terminal in a non-interactive session.
src/lread.c (openp): If both FILENAME and SUFFIX are unibyte, make
sure we concatenate them into a unibyte string.
src/fileio.c (make_temp_name): Encode PREFIX, and decode the
resulting temporary name before returning it to the caller.
(Fexpand_file_name): If NAME is pure-ASCII and DEFAULT_DIRECTORY
is a unibyte string, convert NAME to a unibyte string to ensure

*scratch* in multibyte form. The original problem which led to
that is described in
http://lists.gnu.org/archive/html/emacs-pretest-bug/2004-11/msg00532.html,
but it was solved long ago.
lisp/startup.el (normal-top-level): Move setting eol-mnemonic-unix,
eol-mnemonic-mac, eol-mnemonic-dos, and also setup of the locale
environment and decoding all of the default-directory's to here
from command-line.

lisp/loadup.el: Error out if default-directory is a multibyte string
when we are dumping.
lisp/Makefile.in (emacs): Don't set LC_ALL=C.
