CookieJar doesn't support the path-match and domain-match algorithms from [RFC 6265](https://tools.ietf.org/html/rfc6265#section-5.1.3), while cookie_store does.
This fixes some issues with the cookie matching algorithm currently in ureq. For instance,
the domain-match uses substring matching rather than the RFC 6265 algorithm.
This deletes two tests:
match_cookies_returns_nothing_when_no_cookies didn't test much
agent_cookies was failing because cookie_store rejects cookies on the `test:` scheme.
The way around this is to set up a testserver - but it turns out cookies_on_redirect already
does that, and covers the same cases and more.
This changes some cookie-related behavior:
- Cookies could previously be sent to a wrong domain - e.g. a cookie set on `example.com`
could go to `example.com.evil.com` or `evilexample.com`. Probably no one was relying on
this, since it's quite broken.
- A cookie with a path of `/foo` could be sent on a request to `/foobar`, but now it can't.
- Cookies could previously be set on IP addresses, but now they can't.
- Cookies could previously be set for domains other than the one on the request (or its
parents), but now they can't.
- When a cookie had no domain attribute, it would previously get the domain from the
request, and subsequently be sent to that domain and all subdomains. Now, it will only
be sent to that exact domain (host-only).
That last one is probably the most likely to break people, since someone could depend
on it without realizing it was broken behavior.
Since tls and native-tls are mutually exclusive, we can't use
all-features anymore. Instead we enumerate the features needed to
build the docs for docs.rs.
This loads a list of top domain names (e.g. from
https://tranco-list.eu/) and tries to fetch them all, in parallel. This
can be used to exercise ureq and find panics.
This removes the necessity to take the result of Response::into_json and
having to convert it into a struct by using serde_json::from_value
This adds no new dependencies since serde_json already depends on serde.
Users of ureq will have to include `serde_derive` either by importing it
directly or by using serde with the `derive` feature, unless they want to
manually implement `Deserialize` on their structs.
