(__gconv_compare_alias): New function. * locale/findlocale.c (_nl_find_locale): Ise __gconv_compare_alias instead of calling __gconv_lookup_alias twice and compare here. --- iconv/gconv_charset.h | 3 ++- iconv/gconv_db.c | 13 ++++++++++--- iconv/gconv_int.h | 6 ++++++ 3 files changed, 18 insertions(+), 4 deletions(-) (limited to 'iconv') diff --git a/iconv/gconv_charset.h b/iconv/gconv_charset.h index 1e2b76b..b0b2807 100644 --- a/iconv/gconv_charset.h +++ b/iconv/gconv_charset.h @@ -57,4 +57,5 @@ upstr (char *dst, const char *str) /* If NAME is an codeset alias expand it. */ -extern const char *__gconv_lookup_alias (const char *name); +extern int __gconv_compare_alias (const char *name1, const char *name2) + internal_function; diff --git a/iconv/gconv_db.c b/iconv/gconv_db.c index 47861d1..9bd27c5 100644 --- a/iconv/gconv_db.c +++ b/iconv/gconv_db.c @@ -632,13 +632,20 @@ do_lookup_alias (const char *name) } -const char * -__gconv_lookup_alias (const char *name) +int +internal_function +__gconv_compare_alias (const char *name1, const char *name2) { + int result; + /* Ensure that the configuration data is read. */ __libc_once (once, __gconv_read_conf); - return do_lookup_alias (name) ?: name; + if (__gconv_compare_alias_cache (name1, name2, &result) != 0) + result = strcmp (do_lookup_alias (name1) ?: name1, + do_lookup_alias (name2) ?: name2); + + return result; } diff --git a/iconv/gconv_int.h b/iconv/gconv_int.h index 13698d8..3b5f195 100644 --- a/iconv/gconv_int.h +++ b/iconv/gconv_int.h @@ -188,6 +188,12 @@ extern int __gconv_lookup_cache (const char *toset, const char *fromset, int flags) internal_function; +/* Compare the two name for whether they are after alias expansion the + same.
