Move `default-file-system-ignore-case' to C; fix bug in directory hash tables src/ChangeLog addition: 2010-05-16 Aidan Kehoe <kehoea@parhasard.net> Move `default-file-system-ignore-case' to C; pay attention to it in creating the directory hash tables for #'locate-file. Fix a bug where #'eq was specified when creating directory hash tables in dired.c. * config.h.in (DEFAULT_FILE_SYSTEM_IGNORE_CASE): This is 1 on Darwin. * dired.c (make_directory_hash_table): If #'file-system-ignore-case-p gives non-nil for a directory, created the associated hash table with #'equalp as its test. Never use #'eq as a directory hash table test. * fileio.c (vars_of_fileio): Move `default-file-system-ignore-case' here, so it can be a constant boolean reflecting a compile-time #define. * lisp.h: Update the declaration of make_directory_hash_table; remove the declaration of wasteful_word_to_lisp, which was #ifdef'd out. * lread.c (Flocate_file): Take out a debugging statement from this function. (locate_file_refresh_hashing): Call make_directory_hash_table with a Lisp string, not an Ibyte pointer. (vars_of_lread): If DEFAULT_FILE_SYSTEM_IGNORE_CASE is defined, use #'equalp as the hash table test for locate-file-hash-table, not #'equal. * s/win32-common.h (DEFAULT_FILE_SYSTEM_IGNORE_CASE): Case should normally be ignored in file names on Win32. lisp/ChangeLog addition: 2010-05-16 Aidan Kehoe <kehoea@parhasard.net> * files.el (default-file-system-ignore-case): Move this to fileio.c, where it's a constant boolean variable initialised at dump time.
