From 01b14242cccb03c411d3eb1437c99da663c95507 Mon Sep 17 00:00:00 2001 From: psykose Date: Wed, 2 Mar 2022 21:16:54 +0100 Subject: accept null pointer as message argument to gettext functions the change to support passing null was rejected in the past on the grounds that GNU gettext documented it as undefined, on an assumption that only glibc accepted it and that the standalone GNU gettext did not. but it turned out that both explicitly accept it. in light of this, since some software assumes null can be passed safely, allow it. --- src/locale/dcngettext.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src') diff --git a/src/locale/dcngettext.c b/src/locale/dcngettext.c index d1e6c6d1..0b53286d 100644 --- a/src/locale/dcngettext.c +++ b/src/locale/dcngettext.c @@ -132,6 +132,9 @@ char *dcngettext(const char *domainname, const char *msgid1, const char *msgid2, struct binding *q; int old_errno = errno; + /* match gnu gettext behaviour */ + if (!msgid1) goto notrans; + if ((unsigned)category >= LC_ALL) goto notrans; if (!domainname) domainname = __gettextdomain(); -- cgit 1.4.1
