2011-04-12  Paul Eggert  <eggert@cs.ucla.edu>

	* sysdep.c (emacs_read, emacs_write): Check for negative sizes
	since callers should never pass a negative size.
	Change the signature to match that of plain 'read' and 'write'; see
	<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
	* lisp.h: Update prototypes of emacs_write and emacs_read.

2011-04-11  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (redisplay_window): Don't try to determine the character
	position of the scroll margin if the window start point w->startp
	is outside the buffer's accessible region.  (Bug#8468)

2011-04-10  Eli Zaretskii  <eliz@gnu.org>

	Fix write-region and its subroutines for buffers > 2GB.
	* fileio.c (a_write, e_write): Modify declaration of arguments and
	local variables to support buffers larger than 2GB.
	(Fcopy_file): Use EMACS_INT for return value of emacs_read.

	* sysdep.c (emacs_write, emacs_read): Use ssize_t for last
	argument, local variables, and return value.

	* lisp.h: Update prototypes of emacs_write and emacs_read.

	* sound.c (vox_write): Use ssize_t for return value of emacs_write.

2011-04-10  Paul Eggert  <eggert@cs.ucla.edu>

	* xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

	Fix more problems found by GCC 4.6.0's static checks.

	* xdisp.c (vmessage): Use a better test for character truncation.

	* charset.c (load_charset_map): <, not <=, for optimization,
	and to avoid potential problems with integer overflow.
	* chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
	* casetab.c (set_identity, shuffle): Likewise.
	* editfns.c (Fformat): Likewise.
	* syntax.c (skip_chars): Likewise.

	* xmenu.c (set_frame_menubar): Allocate smaller local vectors.
	This also lets GCC 4.6.0 generate slightly better loop code.

	* callint.c (Fcall_interactively): <, not <=, for optimization.
	(Fcall_interactively): Count the number of arguments produced,
	not the number of arguments given.  This is simpler and lets GCC
	4.6.0 generate slightly better code.

	* ftfont.c: Distingish more carefully between FcChar8 and char.
	The previous code passed unsigned char * to a functions like
	strlen and xstrcasecmp that expect char *, which does not
	conform to the C standard.
	(get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
	arguments to FcPatternGetString, and explicitly cast FcChar8 * to
	char * when the C standard requires it.

	* keyboard.c (read_char): Remove unused var.

	* eval.c: Port to Windows vsnprintf (Bug#8435).
	Include <limits.h>.
	(SIZE_MAX): Define if the headers do not.
	(verror): Do not give up if vsnprintf returns a negative count.
	Instead, grow the buffer.  This ports to Windows vsnprintf, which
	does not conform to C99.  Problem reported by Eli Zaretskii.
	Also, simplify the allocation scheme, by avoiding the need for
	calling realloc, and removing the ALLOCATED variable.

	* eval.c (verror): Initial buffer size is 4000 (not 200) bytes.

	Remove invocations of doprnt, as Emacs now uses vsnprintf.
	But keep the doprint source code for now, as we might revamp it
	and use it again (Bug#8435).
	* lisp.h (doprnt): Remove.
	* Makefile.in (base_obj): Remove doprnt.o.
	* deps.mk (doprnt.o): Remove.

	error: Print 32- and 64-bit integers portably (Bug#8435).
	Without this change, on typical 64-bit hosts error ("...%d...", N)
	was used to print both 32- and 64-bit integers N, which relied on
	undefined behavior.
	* lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
	New macro.
	* lisp.h (error, verror): Mark as printf-like functions.
	* eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
	Report overflow in size calculations when allocating printf buffer.
	Do not truncate output string at its first null byte.
	* xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
	Truncate the output at a character boundary, since vsnprintf does not
	do that.
	* charset.c (check_iso_charset_parameter): Convert internal
	character to string before calling 'error', since %c now has the
	printf meaning.
	* coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
	overflow when computing char to be passed to 'error'.  Do not
	pass Lisp_Object to 'error'; pass the integer instead.
	* nsfns.m (Fns_do_applescript): Use int, not long, since it's
	formatted with plain %d.

	* eval.c (internal_lisp_condition_case): Don't pass spurious arg.

	* keyboard.c (access_keymap_keyremap): Print func name, not garbage.

	* coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

	* xterm.c (x_catch_errors): Remove duplicate declaration.

	* term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.

	* xdisp.c, lisp.h (message_nolog): Remove; unused.

2011-04-10  Jim Meyering  <meyering@redhat.com>

	use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
	* gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
	return ssize_t not "int", and use size_t as the buffer length.
	(emacs_gnutls_write): Likewise, and make the buffer pointer "const".
	* gnutls.h: Update declarations.
	* process.c (read_process_output): Use ssize_t, to match.
	(send_process): Likewise.

2011-04-09  Chong Yidong  <cyd@stupidchicken.com>

	* image.c (Fimagemagick_types): Doc fix, and comment cleanup.

2011-04-09  Chong Yidong  <cyd@stupidchicken.com>

	* ftfont.c (get_adstyle_property, ftfont_pattern_entity): Use
	unsigned char, to match FcChar8 type definition.

	* xterm.c (handle_one_xevent):
	* xmenu.c (create_and_show_popup_menu):
	* xselect.c (x_decline_selection_request)
	(x_reply_selection_request): Avoid type-punned deref of X events.

2011-04-09  Eli Zaretskii  <eliz@gnu.org>

	Fix some uses of `int' instead of EMACS_INT.
	* search.c (string_match_1, fast_string_match)
	(fast_c_string_match_ignore_case, fast_string_match_ignore_case)
	(scan_buffer, find_next_newline_no_quit)
	(find_before_next_newline, search_command, Freplace_match)
	(Fmatch_data): Make some `int' variables be EMACS_INT.

	* xdisp.c (display_count_lines): 3rd argument and return value now
	EMACS_INT.  All callers changed.
	(pint2hrstr): Last argument is now EMACS_INT.

	* coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
	(detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
	(detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

	Declare EMACS_INT.
	(ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
	(encode_invocation_designation): Last argument P_NCHARS is now
	EMACS_INT.
	(decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
	(produce_chars): from_nchars and to_nchars are now EMACS_INT.

	* coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
	All users changed.

	* ccl.c (Fccl_execute_on_string): Declare some variables
	EMACS_INT.

	to system-supplied API.

	* eval.c (Fsignal): Remove excess argument to 'fatal'.

	* coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
	This avoids several warnings with gcc -Wstrict-overflow.
	(DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
	directly, rather than having caller test rule sign.  This avoids
	some unnecessary tests.
	* composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
	(COMPOSITION_ENCODE_RULE): Arguments now must be valid.  This
	affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

	* xfont.c (xfont_text_extents): Remove var that was set but not used.
	(xfont_open): Avoid unnecessary tests.

	(lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
	(safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.

	* print.c (print_error_message): Avoid int overflow.

	* font.c (font_list_entities): Redo for clarity,
	so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

	* font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
	(font_score): Avoid potential overflow in diff calculation.

	* fns.c (substring_both): Remove var that is set but not used.
	(sxhash): Redo loop for clarity and to avoid wraparound warning.

	* eval.c (funcall_lambda): Rename local to avoid shadowing.

	* alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
	Otherwise, GCC 4.6.0 optimizes the loop check away since the check
	can always succeed if overflow has undefined behavior.

	* search.c (boyer_moore, wordify): Remove vars set but not used.
	(wordify): Omit three unnecessary tests.

	* indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
	All callers changed.  This avoids the need for an unused var.

	* casefiddle.c (casify_region): Remove var that is set but not used.

	All callers changed.
	(decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
	(decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
	(decode_coding_charset): Remove vars that are set but not used.

	* bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
	that is set but not used.

	* print.c (print_object): Remove var that is set but not used.

	Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
	The gnulib version avoids calling malloc in the usual case,
	and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
	* fileio.c (Ffile_symlink_p): Use emacs_readlink.
	* filelock.c (current_lock_owner): Likewise.
	* lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

2011-04-03  Jan Djärv  <jan.h.d@swipnet.se>

	* nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
	if not defined (Bug#8403).

2011-04-02  Juanma Barranquero  <lekktu@gmail.com>

	* xdisp.c (display_count_lines): Remove parameter `start',
	unused since 1998-01-01T02:27:27Z!rms@gnu.org.  All callers changed.

	* lisp.h (struct Lisp_Symbol): New field `declared_special'.

	* keyboard.c (eval_dyn): New fun.
	(menu_item_eval_property): Use it.

	* image.c (parse_image_spec): Use Ffunctionp.

	* fns.c (concat, mapcar1): Accept byte-code-functions.

	* eval.c (Fsetq): Handle lexical vars.
	(Fdefun, Fdefmacro, Ffunction): Make closures when needed.
	(Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
	(FletX, Flet): Obey lexical binding.
	(Fcommandp): Handle closures.

	(apply_lambda): Remove `eval_flags'.
	(funcall_lambda): Handle closures and new byte-code-functions.

	(syms_of_eval): Initialize the Vinternal_interpreter_environment var,
	but without exporting it to Lisp.

	* doc.c (Fdocumentation, store_function_docstring):
	* data.c (Finteractive_form): Handle closures.

	* callint.c (Fcall_interactively): Preserve lexical-binding mode for
	interactive spec.

	* bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN): New
	byte-codes.
	(exec_byte_code): New function extracted from Fbyte_code to handle new

2011-03-31  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (SCROLL_LIMIT): New macro.
	(try_scrolling): Use it when setting scroll_limit.  Limit
	scrolling to 100 screen lines.
	(redisplay_window): Even when falling back on "recentering",
	position point in the window according to scroll-conservatively,
	scroll-margin, and scroll-*-aggressively variables.  (Bug#6671)

	(try_scrolling): When point is above the window, allow searching
	as far as scroll_max, or one screenful, to compute vertical
	distance from PT to the scroll margin position.  This prevents
	try_scrolling from unnecessarily failing when
	scroll-conservatively is set to a value slightly larger than the
	window height.  Clean up the case of PT below the margin at bottom
	of window: scroll_max can no longer be INT_MAX.  When aggressive
	scrolling is in use, don't let point enter the opposite scroll
	margin as result of the scroll.
	(syms_of_xdisp) <scroll-conservatively>: Document the
	threshold of 100 lines for never-recentering scrolling.

	unused since 1999-07-21T21:43:52Z!gerd@gnu.org.  All callers changed.

	* indent.c (Fvertical_motion):
	* window.c (window_scroll_pixel_based, Frecenter):

2011-03-30  Stefan Monnier  <monnier@iro.umontreal.ca>

	* eval.c (struct backtrace): Don't cheat with negative numbers, but do
	steal a few bits to be more compact.
	(interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
	Remove unneeded casts.

	* menu.c (digest_single_submenu): Omit unused local var.
	* dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
	Omit unused local var.

	* keyboard.c (parse_modifiers_uncached, parse_modifiers):
	Don't assume string length fits in int.
	(keyremap_step, read_key_sequence): Use size_t for sizes.
	(read_key_sequence): Don't check last_real_key_start redundantly.

	* callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
	instead of alloca (Bug#8344).

	* eval.c (Fbacktrace): Don't assume nargs fits in int.
	(Fbacktrace_frame): Don't assume nframes fits in int.

	* cm.c (calccost): Turn while-do into do-while, for clarity.

	* keyboard.c (syms_of_keyboard): Use the same style as later

	efficiency gain, and to bypass a gcc -Wstrict-overflow warning.

	* keyboard.c, keyboard.h (num_input_events): Now size_t.
	This avoids undefined behavior on integer overflow, and is a bit
	more convenient anyway since it is compared to a size_t variable.

	Variadic C functions now count arguments with size_t, not int.
	This avoids an unnecessary limitation on 64-bit machines, which
	caused (substring ...) to crash on large vectors (Bug#8344).

	0 if not found, not -1.  All callers changed.

	* alloc.c (garbage_collect): Don't assume stack size fits in int.
	(stack_copy_size): Now size_t, not int.
	(stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

	Fix more problems found by GCC 4.5.2's static checks.

	* coding.c (encode_coding_raw_text): Avoid unnecessary test
	the first time through the loop, since we know p0 < p1 then.
	This also avoids a gcc -Wstrict-overflow warning.

	* lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
	leading to a memory leak, possible in functions like
	load_charset_map_from_file that can allocate an unbounded number
	of objects (Bug#8318).

	* xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
	that could (at least in theory) be that large.

	* xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
	This is less likely to overflow, and avoids undefined behavior if
	overflow does occur.  All callers changed.  Use strtoul to scan

	This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

	* process.c (Fmake_network_process): Use socklen_t, not int,
	where POSIX says socklen_t is required in portable programs.

	socklen_t is wider than int (Bug#8277).
	(Fmake_network_process, server_accept_connection):
	(wait_reading_process_output, read_process_output):
	Likewise.

	Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.

	* lisp.h (child_setup): Now NO_RETURN unless DOS_NT.

	(GC_STRING_CHARS): Remove; not used.
	(Fmemory_limit): Cast sbrk's returned value to char *.

	* regex.c (IF_LINT): Add defn, for benefit of ../lib-src.

	Use functions, not macros, for up- and down-casing (Bug#8254).
	* buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
	(NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove.  All callers changed
	to use the following functions instead of these macros.

	which gcc can warn about.
	(regex_compile, re_match_2_internal): Mark locals as initialized.
	(RETALLOC_IF): Define only if needed.
	(WORDCHAR_P): Likewise.  This one is never needed, but is used

	of the new macros.
	(GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
	argument, for consistency with GCPRO2_VAR, etc: it is now the
	prefix of the variable, not the variable itself.  All uses
	changed.
	* dired.c (directory_files_internal, file_name_completion):
	Rename locals to avoid shadowing.

	Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
	An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
	dired.c's scmp function, had undefined behavior.
	* lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
	(NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
	* buffer.h: ... to here, because these macros use current_buffer,
	and the new implementation with inline functions needs to have
	current_buffer in scope now, rather than later when the macros
	are used.
	(downcase, upcase1): New static inline functions.
	(DOWNCASE, UPCASE1): Reimplement using these functions.
	This avoids undefined behavior in expressions like

	case_temp1 and case_temp2.
	* casetab.c (case_temp1, case_temp2): Remove; no longer needed.
	* lisp.h (case_temp1, case_temp2): Remove their decls.

	* fileio.c (file_name_as_directory, directory_file_name):

	(Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
	signedness issues.
	(Fset_file_times, Finsert_file_contents, auto_save_error):

	(lock_file_1): Rename local to avoid shadowing.

	* buffer.c (fix_overlays_before): Mark locals as initialized.
	(fix_start_end_in_overlays): Likewise.  This function should be
	simplified by using pointers-to-pointers, but that's a different
	matter.
	(switch_to_buffer_1): Now static.
	(Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
	(report_overlay_modification): Rename locals to avoid shadowing.

	* sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
	Fix pointer signedness issue.

	* process.c (serial_open, serial_configure): Move decls from here ...
	* systty.h: ... to here, so that they can be checked.

	* term.c (tputs, tgetent, tgetflag, tgetnum, tparam, tgetstr):
