From 727d9410c4333e920b750907008f3a198452d7f7 Mon Sep 17 00:00:00 2001 From: bapt Date: Sat, 15 Oct 2016 12:38:21 +0000 Subject: [PATCH] MFC r306852 Incorporate a change from OpenBSD by millert@OpenBSD.org Don't warn about valid time zone abbreviations. POSIX through 2000 says that an abbreviation cannot start with ':', and cannot contain ',', '-', '+', NUL, or a digit. POSIX from 2001 on changes this rule to say that an abbreviation can contain only '-', '+', and alphanumeric characters from the portable character set in the current locale. To be portable to both sets of rules, an abbreviation must therefore use only ASCII letters." Adapted from tzcode2015f. This is needed to be able to update tzdata to a newer version git-svn-id: svn://svn.freebsd.org/base/stable/10@307359 ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f --- contrib/tzcode/zic/zdump.c | 24 ++++++++---------------- contrib/tzcode/zic/zic.c | 20 +++----------------- 2 files changed, 11 insertions(+), 33 deletions(-) diff --git a/contrib/tzcode/zic/zdump.c b/contrib/tzcode/zic/zdump.c index 2878a707c..01111fec2 100644 --- a/contrib/tzcode/zic/zdump.c +++ b/contrib/tzcode/zic/zdump.c @@ -212,24 +212,16 @@ const char * const zone; return; cp = abbrp; wp = NULL; - while (isascii((unsigned char) *cp) && isalpha((unsigned char) *cp)) + while (isascii((unsigned char) *cp) && + (isalnum((unsigned char)*cp) || *cp == '-' || *cp == '+')) ++cp; - if (cp - abbrp == 0) - wp = _("lacks alphabetic at start"); - else if (cp - abbrp < 3) - wp = _("has fewer than 3 alphabetics"); + if (cp - abbrp < 3) + wp = _("has fewer than 3 characters"); else if (cp - abbrp > 6) - wp = _("has more than 6 alphabetics"); - if (wp == NULL && (*cp == '+' || *cp == '-')) { - ++cp; - if (isascii((unsigned char) *cp) && - isdigit((unsigned char) *cp)) - if (*cp++ == '1' && *cp >= '0' && *cp <= '4') - ++cp; - if (*cp != '\0') - wp = _("differs from POSIX standard"); - } - if (wp == NULL) + wp = _("has more than 6 characters"); + else if (*cp) + wp = "has characters other than ASCII alphanumerics, '-' or '+'"; + else return; (void) fflush(stdout); (void) fprintf(stderr, diff --git a/contrib/tzcode/zic/zic.c b/contrib/tzcode/zic/zic.c index 5fb8b53c4..00043b794 100644 --- a/contrib/tzcode/zic/zic.c +++ b/contrib/tzcode/zic/zic.c @@ -2615,29 +2615,15 @@ const char * const string; register const char * cp; register char * wp; - /* - ** Want one to ZIC_MAX_ABBR_LEN_WO_WARN alphabetics - ** optionally followed by a + or - and a number from 1 to 14. - */ cp = string; wp = NULL; while (isascii((unsigned char) *cp) && - isalpha((unsigned char) *cp)) + (isalnum((unsigned char)*cp) || *cp == '-' || *cp == '+')) ++cp; - if (cp - string == 0) -wp = _("time zone abbreviation lacks alphabetic at start"); if (noise && cp - string > 3) -wp = _("time zone abbreviation has more than 3 alphabetics"); +wp = _("time zone abbreviation has more than 3 characters"); if (cp - string > ZIC_MAX_ABBR_LEN_WO_WARN) -wp = _("time zone abbreviation has too many alphabetics"); - if (wp == NULL && (*cp == '+' || *cp == '-')) { - ++cp; - if (isascii((unsigned char) *cp) && - isdigit((unsigned char) *cp)) - if (*cp++ == '1' && - *cp >= '0' && *cp <= '4') - ++cp; - } +wp = _("time zone abbreviation has too many characters"); if (*cp != '\0') wp = _("time zone abbreviation differs from POSIX standard"); if (wp != NULL) { -- 2.45.0
