We were generating two whole sets of jobs, for --tests and --docs
separately. But the default invocation of cargo runs both tests and
doctests. We can save some resources and speed up our test runs by
allowing cargo to do both in one invocation.
* Remove Request::build
* All mutations on Request follow builder pattern
The previous `build()` on request was necessary because mutating
functions did not follow a proper builder pattern (taking `&mut self`
instead of `mut self`). With a proper builder pattern, the need for
`.build()` goes away.
* All Request body and call methods consume self
Anything which "executes" the request will now consume the `Request`
to produce a `Result<Response>`.
* Move all config from request to agent builder
Timeouts, redirect config, proxy settings and TLS config are now on
`AgentBuilder`.
* Rename max_pool_connections -> max_idle_connections
* Rename max_pool_connections_per_host -> max_idle_connections_per_host
Consistent internal and external naming.
* Introduce new AgentConfig for static config created by builder.
`Agent` can be seen as having two parts. Static config and a mutable
shared state between all states. The static config goes into
`AgentConfig` and the mutable shared state into `AgentState`.
* Replace all use of `Default` for `new`.
Deriving or implementing `Default` makes for a secondary instantiation
API. It is useful in some cases, but gets very confusing when there
is both `new` _and_ a `Default`. It's especially devious for derived
values where a reasonable default is not `0`, `false` or `None`.
* Remove feature native_tls, we want only native rustls.
This feature made for very clunky handling throughout the code. From a
security point of view, it's better to stick with one single TLS API.
Rustls recently got an official audit (very positive).
https://github.com/ctz/rustls/tree/master/audit
Rustls deliberately omits support for older, insecure TLS such as TLS
1.1 or RC4. This might be a problem for a user of ureq, but on balance
not considered important enough to keep native_tls.
* Remove auth and support for basic auth.
The API just wasn't enough. A future reintroduction should at least
also provide a `Bearer` mechanism and possibly more.
* Rename jar -> cookie_store
* Rename jar -> cookie_tin
Just make some field names sync up with the type.
* Drop "cookies" as default feature
The need for handling cookies is probably rare, let's not enable it by
default.
* Change all feature checks for "cookie" to "cookies"
The outward facing feature is "cookies" and I think it's better form
that the code uses the official feature name instead of the optional
library "cookies".
* Keep `set` on Agent level as well as AgentBuilder.
The idea is that an auth exchange might result in a header that need
to be set _after_ the agent has been built.
This emulates the test matrix that gets run in CI, making it easier to
find failures locally.
There was one conflict in the matrix: when JSON is enabled and TLS is
disabled, two of the doctests would fail. This was previous worked
around as an exclude in the github workflow. I changed the JSON doctest
to use HTTP instead.
