Pass character count from coding systems to buffer insertion code. src/ChangeLog addition: 2014-01-16 Aidan Kehoe <kehoea@parhasard.net> Pass character count information from the no-conversion and unicode coding systems to the buffer insertion code, making #'find-file on large buffers a little snappier (if ERROR_CHECK_TEXT is not defined). * file-coding.c: * file-coding.c (coding_character_tell): New. * file-coding.c (conversion_coding_stream_description): New. * file-coding.c (no_conversion_convert): Update characters_seen when decoding. * file-coding.c (no_conversion_character_tell): New. * file-coding.c (lstream_type_create_file_coding): Create the no_conversion type with data. * file-coding.c (coding_system_type_create): Make the character_tell method available here. * file-coding.h: * file-coding.h (struct coding_system_methods): Add a new character_tell() method, passing charcount information from the coding systems to the buffer code, avoiding duplicate bytecount-to-charcount work especially with large buffers. * fileio.c (Finsert_file_contents_internal): Update this to pass charcount information to buffer_insert_string_1(), if that is available from the lstream code. * insdel.c: * insdel.c (buffer_insert_string_1): Add a new CCLEN argument, giving the character count of the string to insert. It can be -1 to indicate that te function should work it out itself using bytecount_to_charcount(), as it used to. * insdel.c (buffer_insert_raw_string_1): * insdel.c (buffer_insert_lisp_string_1): * insdel.c (buffer_insert_ascstring_1): * insdel.c (buffer_insert_emacs_char_1): * insdel.c (buffer_insert_from_buffer_1): * insdel.c (buffer_replace_char): Update these functions to use the new calling convention. * insdel.h: * insdel.h (buffer_insert_string): Update this header to reflect the new buffer_insert_string_1() argument. * lstream.c (Lstream_character_tell): New. Return the number of characters *read* and seen by the consumer so far, taking into account the unget buffer, and buffered reading. * lstream.c (Lstream_unread): Update unget_character_count here as appropriate. * lstream.c (Lstream_rewind): Reset unget_character_count here too. * lstream.h: * lstream.h (struct lstream): Provide the character_tell method, add a new field, unget_character_count, giving the number of characters ever passed to Lstream_unread(). Declare Lstream_character_tell(). Make Lstream_ungetc(), which happens to be unused, an inline function rather than a macro, in the course of updating it to modify unget_character_count. * print.c (output_string): Use the new argument to buffer_insert_string_1(). * tests.c: * tests.c (Ftest_character_tell): New test function. * tests.c (syms_of_tests): Make it available. * unicode.c: * unicode.c (struct unicode_coding_stream): * unicode.c (unicode_character_tell): New method. * unicode.c (unicode_convert): Update the character counter as appropriate. * unicode.c (coding_system_type_create_unicode): Make the character_tell method available.
