* 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.
* Change ordering on TestServer's atomic bool to SeqCst

This feature was broken in #67, which reset timeouts on the
stream before passing it to set_stream.
As part of this change, refactor the internal storage of
timeouts on the Request object to use Option<Duration>.
Remove the deadline field on Response. It wasn't used. The
deadline field on unit was used instead.
Add a unittest.
Previously, Agent stored most of its state in one big
Arc<Mutex<AgentState>>. This separates the Arc from the Mutexes.
Now, Agent is a thin wrapper around an Arc<AgentState>. The individual
components that need locking, ConnectionPool and CookieStore, now are
responsible for their own locking.
There were a couple of reasons for this. Internal components that needed
an Agent were often instead carrying around an Arc<Mutex<AgentState>>.
This felt like the components were too intertwined: those other
components shouldn't have to care quite so much about how Agent is
implemented. Also, this led to compromises of convenience: the Proxy on
Agent wound up stored inside the `Arc<Mutex<AgentState>>` even though it
didn't need locking. It was more convenient that way because that was
what Request and Unit had access too.
The other reason to push things down like this is that it can reduce
lock contention. Mutations to the cookie store don't need to lock the
connection pool, and vice versa. This was a secondary concern, since I
haven't actually profiled these things and found them to be a problem,
but it's a happy result of the refactoring.
Now all the components outside of Agent take an Agent instead of
AgentState.
In the process I removed `Agent.cookie()`. Its API was hard to use
correctly, since it didn't distinguish between cookies on different
hosts. And it would have required updates as part of this refactoring.
I'm open to reinstating some similar functionality with a refreshed API.
I kept `Agent.set_cookie`, but updated its method signature to take a
URL as well as a cookie.
Many of ConnectionPool's methods went from `&mut self` to `&self`,
because ConnectionPool is now using interior mutability.
This is a step towards allowing our tests to run without network access,
which will make them more resilient and faster.
Replace the URL in one instance of an HTTPS test that didn't need HTTPS.
In the process, rename set_foo methods to just foo, since methods on the
builder will always be setters.
Adds a new() method on ConnectionPool so it can be constructed directly
with the desired limits. Removes the setter methods on ConnectionPool
for those limits. This means that connection limits can only be set when
an Agent is built.
There were two tests that verify Send and Sync implementations, one for
Agent and one for Request. This PR moves the Request test to request.rs,
and changes both tests to more directly verify the traits. There may be
another way to do this, I'm not sure.
This adds validation of header values on receive, and of both header
names and header values on send. This doesn't change the return
type of set to be a Result, it just validates when the request is
sent. Also removes the section in the README describing handling
of invalid headers, and updates a test that verified acceptance of
non-ASCII headers so that it verifies rejection of them instead.
Gets rid of synthetic_error, and makes the various send_* methods return `Result<Response, Error>`.
Introduces a new error type "HTTP", which represents an error due to status codes 4xx or 5xx.
The HTTP error type contains a boxed Response, so users can read the actual response if they want.
Adds an `error_for_status` setting to disable the functionality of treating 4xx and 5xx as errors.
Adds .unwrap() to a lot of tests.
Fixes#128.
CONNECT, specified at https://tools.ietf.org/html/rfc7231#section-4.3.6,
says:
> if successful, thereafter restrict its behavior to blind forwarding
> of packets, in both directions, until the tunnel is closed.
ureq doesn't actually support the semantics of CONNECT, since it doesn't
offer a bidirectional channel on a Response. So I'm fairly confident no
one is using these methods.
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.
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.
When running tests locally, this error can surface.
```
---- test::agent_test::custom_resolver stdout ----

```
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.
Previously we had a special case for BadStatusRead that would happen
only when we got a ConnectionAborted error reading the status line.
However, sometimes we get ConnectionReset instead. Also the HTTP
spec says that idempotent requests may be retried anytime a connection
is closed prematurely.
The change treats as retryable any ConnectionAborted OR ConnectionReset
error while reading the status line and headers. It removes the special
case BadStatusRead error.
Fixes#165 (I think).
Previously any io::Error on reading a status line or response headers
would be unconditionally mapping into BadStatus or BadHeader. I think
it's better to pass through the actual io::Error.
BadStatusRead is still kept, since it has special status when dealing
with timed out connections, and BadStatus is still used when the status
line is malformed.
