Ensure host offset & length are initialized - fuzzer found possible leaks - #440

this should be taken care of already by

http_parser_url_init(struct http_parser_url *u) {
  memset(u, 0, sizeof(*u));
}

cool so http_parser_parse_url should call that?

The user of the library should call that before calling http_parser_parse_url(). Or, alternatively, the struct http_parser_url might be a member of a larger struct that was memset() all at once, or was allocated with calloc(), in which case the redundant clearing could be skipped ...

If there's any "bug" here, it's that http_parser_parse_url() is only very briefly mentioned and is not really documented ... just the existence of http_parser_url_init(struct http_parser_url *u) is there to imply you should initialize the struct.

ok cool of the 3 references to it being called only 1 in test.c doesn't do this: https://github.com/nodejs/node/blob/bc690e9ef52bebc34cad7ddb40e74472bcb272ca/deps/http_parser/test.c#L2614
not a big deal! still it couldn't hurt to 0 out the struct in case someone forgets to initialize it no? Otherwise just close & ignore this - thanks! Or I can create another PR that just calls http_parser_url_init from http_parser_parse_url - is there ever a case where you don't want to do this (except the case that maybe the caller has already done so)?

Looks like a bug in the test to me.
I'm not a maintainer though, just trying to help clarify the situation.
