[HACKERS] plperl_helpers.h fix for clang
clang warns about that newish SvREFCNT_inc(sv) call in plperl_helpers.h about an unused return value, because the macro expansion of SvREFCNT_inc(sv) returns sv. The merit of that warning might be debatable, but it seems easy to fix by using SvREFCNT_inc_void(sv) instead. And we could use SvREFCNT_inc_simple_void(sv), since sv doesn't have any side effects, but that's optional. Any concerns? -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Hrm I can't seem to find either of those functions in my copy of perl 5.8.1 or 5.16.0. I also looked for _inc_ in the event I got casing wrong :-(. Perhaps I misunderstood, are you proposing to introduce those functions? Im fine with that. Or doing (void)SvREFCNT_inc(). -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Doh, it is indeed there in 5.16.0, looks like it got added in 5.10 :-(.
