From 3ec6e6e8a0870a32357689e2179d845700539623 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Tue, 31 Jan 2017 10:01:45 +0100 Subject: urlmatch: split host and port fields in `struct url_info` The `url_info` structure contains information about a normalized URL with the URL's components being represented by different fields. The host and port part though are to be accessed by the same `host` field, so that getting the host and/or port separately becomes more involved than really necessary. To make the port more readily accessible, split up the host and port fields. Namely, the `host_len` will not include the port length anymore and a new `port_off` field has been added which includes the offset to the port, if available. The only user of these fields is `url_normalize_1`. This change makes it easier later on to treat host and port differently when introducing globs for domains.
