Move the #'query-coding-region implementation to C.
This is necessary because there is no reasonable way to access the
corresponding mswindows-multibyte functionality from Lisp, and we need such
functionality if we're going to have a reliable and portable
#'query-coding-region implementation. However, this change doesn't yet
provide #'query-coding-region for the mswindow-multibyte coding systems,
there should be no functional differences between an XEmacs with this change
and one without it.

* mule-coding.c (struct fixed_width_coding_system):
Add a new coding system type, fixed_width, and implement it. It
uses the CCL infrastructure but has a much simpler creation API,
and its own query_method, formerly in lisp/mule/mule-coding.el.
* unicode.c:
Move the Unicode query method implementation here from
unicode.el.
* lisp.h: Declare Fmake_coding_system_internal, Fcopy_range_table
here.
* intl-win32.c (complex_vars_of_intl_win32):
Use Fmake_coding_system_internal, not Fmake_coding_system.
* general-slots.h: Add Qsucceeded, Qunencodable, Qinvalid_sequence
here.
* file-coding.h (enum coding_system_variant):
Add fixed_width_coding_system here.
(struct coding_system_methods):
Add query_method and query_lstream_method to the coding system
methods.
Provide flags for the query methods.
Declare the default query method; initialise it correctly in
INITIALIZE_CODING_SYSTEM_TYPE.
* file-coding.c (default_query_method):
New function, the default query method for coding systems that do
not set it. Moved from coding.el.
(make_coding_system_1):
Accept new elements in PROPS in #'make-coding-system; aliases, a
list of aliases; safe-chars and safe-charsets (these were
previously accepted but not saved); and category.
(Fmake_coding_system_internal):
New function, what used to be #'make-coding-system--on Mule
builds, we've now moved some of the functionality of this to
Lisp.
(Fcoding_system_canonical_name_p):
Move this earlier in the file, since it's now called from within
make_coding_system_1.
(Fquery_coding_region):
Move the implementation of this here, from coding.el.
(complex_vars_of_file_coding):
Call Fmake_coding_system_internal, not Fmake_coding_system;
specify safe-charsets properties when we're a mule build.
* extents.h (mouse_highlight_priority, Fset_extent_priority,
Fset_extent_face, Fmap_extents):
Make these available to other C files.
lisp/ChangeLog addition:
2009-09-19 Aidan Kehoe <kehoea@parhasard.net>
Move the #'query-coding-region implementation to C.
* coding.el:
Consolidate code that depends on the presence or absence of Mule
at the end of this file.
(default-query-coding-region, query-coding-region):
Move these functions to C.
(default-query-coding-region-safe-charset-skip-chars-map):
Remove this variable, the corresponding C variable is
Vdefault_query_coding_region_chartab_cache in file-coding.c.
(query-coding-string): Update docstring to reflect actual multiple
values, be more careful about not modifying a range table that
we're currently mapping over.
(encode-coding-char): Make the implementation of this simpler.
(featurep 'mule): Autoload #'make-coding-system from
mule/make-coding-system.el if we're a mule build; provide an
appropriate compiler macro.
Do various non-mule compatibility things if we're not a mule
build.
* update-elc.el (additional-dump-dependencies):
Add mule/make-coding-system as a dump time dependency if we're a
mule build.
* unicode.el (ccl-encode-to-ucs-2):
(decode-char):
(encode-char):
Move these earlier in the file, for the sake of some byte compile
warnings.
(unicode-query-coding-region):
Move this to unicode.c
* mule/make-coding-system.el:
New file, not dumped. Contains the functionality to rework the
arguments necessary for fixed-width coding systems, and contains
the implementation of #'make-coding-system, which now calls
#'make-coding-system-internal.
* mule/vietnamese.el (viscii):
* mule/latin.el (iso-8859-2):
(windows-1250):
(iso-8859-3):
(iso-8859-4):
(iso-8859-14):

(koi8-u):
(windows-1251):
(alternativnyj):
(koi8-ru):
(koi8-t):
(koi8-c):
(koi8-o):
* mule/arabic.el (iso-8859-6):
(windows-1256):
Move all these coding systems to being of type fixed-width, not of
type CCL. This allows the distinct query-coding-region for them to
be in C, something which will eventually allow us to implement
query-coding-region for the mswindows-multibyte coding systems.
* mule/general-late.el (posix-charset-to-coding-system-hash):
Document why we're pre-emptively persuading the byte compiler that
the ELC for this file needs to be written using escape-quoted.
Call #'set-unicode-query-skip-chars-args, now the Unicode
query-coding-region implementation is in C.
* mule/thai-xtis.el (tis-620):
Don't bother checking whether we're XEmacs or not here.
* mule/mule-coding.el:
Move the eight bit fixed-width functionality from this file to
make-coding-system.el.
tests/ChangeLog addition:
2009-09-19 Aidan Kehoe <kehoea@parhasard.net>
* automated/mule-tests.el:
Check a coding system's type, not an 8-bit-fixed property, for
whether that coding system should be treated as a fixed-width
coding system.
* automated/query-coding-tests.el:
Don't test the query coding functionality for mswindows-multibyte
coding systems, it's not yet implemented.

61 | |
62 "Mule-izing" is the process of going through a file and eliminating | |
63 assumptions that the internal format (Ibyte * text) is the same as the | |
64 external format used by library routines. Mule-ization should also | |
65 include replacing *ALL* raw references to `char' or `unsigned char' with | |
66 one of the self-documenting types created below. How exactly to do the | |
67 conversion, and how to write correctly Mule-ized code, is described in | |
68 the internals manual. Files that say "This file is Mule-ized" have | |
69 been reviewed at some point; that's not to say that incorrect code hasn't | |
70 crept in, though. | |
71 | |
72 "Unicode-splitting" is the process of fixing a file so that it will | |
73 handle external text in Unicode under Microsoft Windows, as appropriate. | |
74 ("splitting" because it needs to handle either Unicode or variable-width | |
75 multibyte depending on the OS -- NT or 9x). See intl-win32.c. | |
76 | |
77 #### is a way of marking problems of any sort. | |
78 | |
79 !!#### marks places that are not properly Mule-ized. | |
80 | |
81 &&#### marks places that need to be fixed in order for the "8-bit mule" | |
82 conversion to work correctly, i.e. in order to support multiple different | |
83 buffer formats under Mule, including a fixed 8-bit format. | |
84 | |
85 ^^#### marks places that need to be fixed in order to eliminate the | |
86 assumption that Ibyte * text is composed of 1-byte units (e.g. UTF-16 | |
87 is composed of 2-byte units and might be a possible format to consider | |
88 for Ibyte * text). | |

303 REMEMBER! These typedefs are purely for documentation purposes; from | |

313 b) [Extbyte] pointer to text in some external format, which can be | |
314 defined as all formats other than the internal one | |
315 c) [Ascbyte] pure ASCII text | |
316 d) [Binbyte] binary data that is not meant to be interpreted as text | |

335 not apply, add a new type of semantics; don't use `char' directly. | |

1115 certain size. This actually uses malloc(), but checks the current stack | |
1116 pointer to see if data from previous alloca() calls needs to be freed. | |
1117 However, this can lead to large heap sizes -- especially since cleanup | |
1118 can only happen in a parent function, and will never happen if (as will | |
1119 often be the case) it's the same function in the same place in the code | |
1120 that keeps tripping the alloca() limit. | |
1121 | |
1122 So we set up a system to periodically force cleanup. Currently we | |
1123 do cleanup: | |
1124 | |
1125 -- Only when there's C alloca() data, and then | |
1126 -- Every stack alloca() or allocation of Lisp data, every call to | |
1127 next_event_internal() [typically near the top of the stack], | |
1128 or every 10th funcall | |
1129 | |
1130 This should not be a big penalty because | |
1131 | |
1132 (a) If there are few C alloca() chunks, checking them will be fast | |
1133 (b) If not, we've allocated a huge amount of heap space (remember, each | |
1134 chunk represents > 256K of heap), and we really want them gone | |
1135 */ | |
1136 | |
1137 /* We use a larger maximum when the choice is alloca() vs. the C alloca() | |
1138 substitute than when the choice is vs. malloc(), because in the former | |
1139 case, our alternative choice is less palatable because the memory may | |
1140 not be freed for awhile. */ | |

1892 | |
1893 /* Note: These macros are for traversing through a list in some format, | |
1894 and executing code that you specify on each member of the list. | |
1895 | |
1896 There are two kinds of macros, those requiring surrounding braces, and | |
1897 those not requiring this. Which type of macro will be indicated. | |
1898 The general format for using a brace-requiring macro is | |
1899 | |
1900 { | |
1901 LIST_LOOP_3 (elt, list, tail) | |
1902 execute_code_here; | |
1903 } | |
1904 | |
1905 or | |
1906 | |
1907 { | |
1908 LIST_LOOP_3 (elt, list, tail) | |
1909 { | |
1910 execute_code_here; | |
1911 } | |
1912 } | |
1913 | |
1914 You can put variable declarations between the brace and beginning of | |
1915 macro, but NOTHING ELSE. | |
1916 | |
1917 The brace-requiring macros typically declare themselves any arguments | |
1918 that are initialized and iterated by the macros. If for some reason | |
1919 you need to declare these arguments yourself (e.g. to do something on | |
1920 them before the iteration starts, use the _NO_DECLARE versions of the | |
1921 macros.) | |
1922 */ | |
1923 | |
1924 /* There are two basic kinds of macros: those that handle "internal" lists | |
1925 that are known to be correctly structured (i.e. first element is a cons | |
1926 or nil, and the car of each cons is also a cons or nil, and there are | |
1927 no circularities), and those that handle "external" lists, where the | |
1928 list may have any sort of invalid formation. This is reflected in | |
1929 the names: those with "EXTERNAL_" work with external lists, and those | |
1930 without this prefix work with internal lists. The internal-list | |
1931 macros will hit an assertion failure if the structure is ill-formed; | |
1932 the external-list macros will signal an error in this case, either a | |
1933 malformed-list error or a circular-list error. | |
1934 */ | |
1935 | |
2367 | 1936 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
1937 surrounding, and iterates through a list, which may or may not known to | |
1938 be syntactically correct. It accepts two args, TAIL (set progressively | |
1939 to each cons starting with the first), and LIST, the list to iterate | |
1940 over. TAIL needs to be defined by the caller. | |
442 | 1941 |
1942 In each iteration, you can retrieve the current list item using XCAR | |
1943 (tail), or destructively modify the list using XSETCAR (tail, | |
1944 ...). */ | |

1952 | |
1953 *** ALL OF THESE MACROS MUST BE DECLARED INSIDE BRACES -- SEE ABOVE. *** | |
1954 | |
1955 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
1956 macros. They take two arguments, an element variable ELT and the list | |
1957 LIST. ELT is automatically declared, and set to each element in turn | |
1958 from LIST. | |
1959 | |
1960 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
1961 argument TAIL, another automatically-declared variable. At each iteration, | |
1962 this one points to the cons cell for which ELT is the car. | |
1963 | |
1964 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
1965 LEN argument, again automatically declared, which counts the number of | |
1966 iterations gone by. It is 0 during the first iteration. | |
1967 | |
1968 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none | |
1969 of the variables are automatically declared, and so you need to declare | |
1970 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.) | |

3565 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
3566 | |
3567 3. When we get to a point in the code where we might garbage collect -- | |
3568 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
3569 at our list of stack-based Lisp_Objects, and if there are any that | |
3570 point to Lisp objects with no non-stack references, see if there are | |
3571 any gcpros pointing to the object, and if not, set a flag indicating | |
3572 that the object is "destroyed". (Don't abort yet because the function | |
3573 might not use the object any more.) | |
