From: handa Date: Wed, 28 Feb 2007 07:28:32 +0000 (+0000) Subject: (get_dir_info): Set dir_info->status to X-Git-Tag: FLT-base~125 X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=2a2f93c2fa2c22829d062679dbe9f4f3a1b24695;p=m17n%2Fm17n-lib.git (get_dir_info): Set dir_info->status to MDB_STATUS_OUTDATED. (check_version): New function. (register_database): Don't call find_database. (register_databases_in_files): Don't register a database of invalid version. (mdatabase__update): Likewise. Avoid unnecessary scanning. --- diff --git a/src/database.c b/src/database.c index d9349e9..5695ea0 100644 --- a/src/database.c +++ b/src/database.c @@ -545,7 +545,7 @@ get_dir_info (char *dirname) dir_info->filename[++len] = '\0'; } dir_info->len = len; - dir_info->status = MDB_STATUS_AUTO; + dir_info->status = MDB_STATUS_OUTDATED; } else dir_info->status = MDB_STATUS_DISABLED; @@ -584,23 +584,66 @@ free_db_info (MDatabaseInfo *db_info) free (db_info); } +static int +check_version (MText *version) +{ + char *verstr = (char *) MTEXT_DATA (version); + char *endp = verstr + mtext_nbytes (version); + int ver[3]; + int i; + + ver[0] = ver[1] = ver[2] = 0; + for (i = 0; verstr < endp; verstr++) + { + if (*verstr == '.') + { + i++; + if (i == 3) + break; + continue; + } + if (! isdigit (*verstr)) + break; + ver[i] = ver[i] * 10 + (*verstr - '0'); + } + return (ver[0] < M17NLIB_MAJOR_VERSION + || (ver[0] == M17NLIB_MAJOR_VERSION + && (ver[1] < M17NLIB_MINOR_VERSION + || (ver[1] == M17NLIB_MINOR_VERSION + && ver[2] <= M17NLIB_PATCH_LEVEL)))); +} + static MDatabase * -register_database (MSymbol tags[4], void *(*loader) (MSymbol *, void *), +register_database (MSymbol tags[4], + void *(*loader) (MSymbol *, void *), void *extra_info, enum MDatabaseStatus status) { - MDatabase *mdb = find_database (tags); - MDatabaseInfo *db_info = NULL; + MDatabase *mdb; + MDatabaseInfo *db_info; + int i; + MPlist *plist; + + if (! mdatabase__list) + mdatabase__list = mplist (); - if (mdb) + for (i = 0, plist = mdatabase__list; i < 4; i++) { - if (loader == load_database) - db_info = mdb->extra_info; + MPlist *pl = mplist__assq (plist, tags[i]); + + if (pl) + pl = MPLIST_PLIST (pl); + else + { + pl = mplist (); + mplist_add (pl, Msymbol, tags[i]); + mplist_push (plist, Mplist, pl); + M17N_OBJECT_UNREF (pl); + } + plist = MPLIST_NEXT (pl); } - else - { - int i; - MPlist *plist; + if (MPLIST_TAIL_P (plist)) + { MSTRUCT_MALLOC (mdb, MERROR_DB); for (i = 0; i < 4; i++) mdb->tag[i] = tags[i]; @@ -611,26 +654,20 @@ register_database (MSymbol tags[4], void *(*loader) (MSymbol *, void *), mdb->extra_info = db_info; } else - mdb->extra_info = extra_info; - if (! mdatabase__list) - mdatabase__list = mplist (); - for (i = 0, plist = mdatabase__list; i < 4; i++) { - MPlist *pl = mplist__assq (plist, tags[i]); - - if (pl) - pl = MPLIST_PLIST (pl); - else - { - pl = mplist (); - mplist_add (pl, Msymbol, tags[i]); - mplist_push (plist, Mplist, pl); - M17N_OBJECT_UNREF (pl); - } - plist = MPLIST_NEXT (pl); + db_info = NULL; + mdb->extra_info = extra_info; } mplist_push (plist, Mt, mdb); } + else + { + mdb = MPLIST_VAL (plist); + if (loader == load_database) + db_info = mdb->extra_info; + else + db_info = NULL; + } if (db_info) { @@ -693,9 +730,16 @@ register_databases_in_files (MSymbol tags[4], glob_t *globbuf, int headlen) : (tags[j] != Mnil && tags[j] != tags2[j])) break; if (j == 4) - register_database (tags2, load_database, - globbuf->gl_pathv[i] + headlen, - MDB_STATUS_AUTO); + { + MText *version = NULL; + + MPLIST_DO (pl, pl) + version = MPLIST_MTEXT_P (pl) ?
