From 39f9121339559738cba5130c818e8920e1a2fa16 Mon Sep 17 00:00:00 2001 From: Andrew Clayton Date: Wed, 21 May 2025 04:13:11 +0100 Subject: Use NULL instead of 0 as null pointer constant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GCC 15 enabled "-Wzero-as-null-pointer-constant" for C, which checks for places where '0' has been used as a null pointer constant. This showed a few places in Unit where we were using '0' instead of the more correct NULL macro. E.g. $ make -j4 EXTRA_CFLAGS=-Wzero-as-null-pointer-constant ... src/nxt_buf.c: In function ‘nxt_buf_mmap_alloc’: src/nxt_buf.h:192:21: error: zero as null pointer constant [-Werror=zero-as-null-pointer-constant] 192 | (bm)->start = 0; \ | ^ src/nxt_buf.c:135:9: note: in expansion of macro ‘nxt_buf_mem_set_size’ 135 | nxt_buf_mem_set_size(&b->mem, size); | ^~~~~~~~~~~~~~~~~~~~ Signed-off-by: Andrew Clayton --- src/ruby/nxt_ruby.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/ruby/nxt_ruby.c') diff --git a/src/ruby/nxt_ruby.c b/src/ruby/nxt_ruby.c index 27b868fe..717816df 100644 --- a/src/ruby/nxt_ruby.c +++ b/src/ruby/nxt_ruby.c @@ -1081,7 +1081,7 @@ nxt_ruby_rack_result_body(nxt_unit_request_info_t *req, VALUE result) } } else if (rb_respond_to(body, rb_intern("each"))) { - rb_block_call(body, rb_intern("each"), 0, 0, + rb_block_call(body, rb_intern("each"), 0, NULL, nxt_ruby_rack_result_body_each, (VALUE) (uintptr_t) req); } else { -- cgit
