use write_str_in_full helper to avoid literal string lengths
In 2d14d65 (Use a clearer style to issue commands to remote helpers, 2009-09-03) I happened to notice two changes like this: - write_in_full(helper->in, "list\n", 5); + + strbuf_addstr(&buf, "list\n"); + write_in_full(helper->in, buf.buf, buf.len); + strbuf_reset(&buf); IMHO, it would be better to define a new function, static inline ssize_t write_str_in_full(int fd, const char *str) { return write_in_full(fd, str, strlen(str)); } and then use it like this: - strbuf_addstr(&buf, "list\n"); - write_in_full(helper->in, buf.buf, buf.len); - strbuf_reset(&buf); + write_str_in_full(helper->in, "list\n"); Thus not requiring the added allocation, and still avoiding the maintenance risk of literal string lengths. These days, compilers are good enough that strlen("literal") imposes no run-time cost. Transformed via this: perl -pi -e \ 's/write_in_full\((.*?), (".*?"), \d+\)/write_str_in_full($1, $2)/'\ $(git grep -l 'write_in_full.*"') Signed-off-by: Jim Meyering <meyering@redhat.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
