Idiomatic rust organizes unit tests into `mod tests { }` blocks
using conditional compilation `[cfg(test)]` to decide whether to
compile the code in that block.
This commit moves "bare" test functions into such blocks, and puts
the block at the bottom of respective file.
The HTTP spec allows for non-ascii values both in the status line and
in headers. ureq does not handle that, we can however provide better
context for when it happens.
The spec says the reason phrase at least must be a space. However in
the wild, there are sites that just ends after the status code.
To be more compatible, this commit relaxes ureq's parsing.
Close#316
Preloading an agent with cookies can be done by providing a prepared
cookie store using `AgentBuilder`. At this point, we don't want direct
state mutation on the `Agent`, so this fn goes away.
Context:
https://github.com/algesten/ureq/issues/203#issuecomment-716385310
* 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.
When running tests locally, this error can surface.
```
---- test::agent_test::custom_resolver stdout ----
thread 'test::agent_test::custom_resolver' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 22, kind: InvalidInput, message: "Invalid argument" }', src/stream.rs:60:13

```
The problem is that setting the timeouts might fail, and this is done
in a From trait where there is not possibility to "bubble" the
io::Error.
```
socket.set_read_timeout(None).unwrap();
socket.set_write_timeout(None).unwrap();
```
This commit moves the resetting of timers to an explicit `Stream::reset()` fn
that must be called every time we're unwrapping the inner stream.
By using `RUSTFLAGS="-D dead_code -D unused-variables -D unused"`, we tell
the compiler to upgrade warnings for unused code to errors. This combined
with a more elaborate test matrix means we can have the CI catch feature
flag combos that cause warnings.
`set_read_timeout` and `set_write_timeout` can cause `ErrorKind::WouldBlock` on unix-y platforms.
This PR normalizes those cases to `ErrorKind::TimedOut`. This will make it simpler higher up in the
stack to deal with timeouts.
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 is not a perfect solution. It works as long as we are not sending
any body bytes. We discover the error first when attempting to read
the response status line. That means we discover the error after
sending body bytes. To be able to re-send the body, we would need to
introduce a buffer to be able to replay the body on the next
request. We don't currently do that.
