This moves Stream's enum into an `Inner` enum, and wraps a single
BufReader around the whole thing. This makes it easier to consistently
treat the contents of Stream as being wrapped in a BufReader.
Also, implement BufRead for DeadlineStream. This means when a timeout
is set, we don't have to set that timeout on the socket with every
small read, just when we fill up the buffer. This reduces the number
of syscalls.
Remove the `Cursor` variant from Stream. It was strictly less powerful
than that `Test` variant, so I've replaced the handful of Cursor uses
with `Test`. Because some of those cases weren't test, I removed the
`#[cfg(test)]` param on the `Test` variant.
Now that all inputs to `do_from_read` are `impl BufRead`, add that
as a type constraint. Change `read_next_line` to take advantage of
`BufRead::read_line`, which may be somewhat faster (though I haven't
benchmarked).
Stream now has an `Inner` enum, and wraps an instance of that enum in a
BufReader. This allows Stream itself to implement BufRead trivially, and
simplify some of the match dispatching. Having Stream implement BufRead
means we can make use of `read_line` instead of our own `read_next_line`
(not done in this PR yet).
Also, removes the `Cursor` variant of the Inner enum in favor of using
the `Test` variant everywhere, since it's strictly more powerful.
It turns out Headers is actually an internal-only API. None of the
user-facing types use it.
Unfortunately, making it unexported also required deleting the doctests,
since doctests can only run against a public interface.
Followup to #56. At the time, doing this would have been an API
break; but we can do this as part of 2.0. This simplifies the API
nicely and creates better symmetry between sending bodies and
receiving them.
This adds a source field to keep track of upstream errors and allow
backtraces, plus a URL field to indicate what URL an error was
associated with.
The enum variants we used to use for Error are now part of a new
ErrorKind type. For convenience within ureq, ErrorKinds can be turned
into an Error with `.new()` or `.msg("some additional information")`.
Error acts as a builder, so additional information can be added after
initial construction. For instance, we return a DnsFailed error when
name resolution fails. When that error bubbles up to Request's
`do_call`, Request adds the URL.
Fixes#232.
This makes src/lib.rs the primary source for crate-level documentation.
I've generated README.md with `cargo readme > README.md`. Since links to
specific documentation items should be relative when possible, but must
be absolute in README.md, I've used the new syntax for intra-rustdoc
links
(https://github.com/rust-lang/rfcs/blob/master/text/1946-intra-rustdoc-links.md),
along with a README.tpl that sets up those links to point at the
absolute versions. `cargo readme` uses the README.tpl by default.
I've also rewritten the crate level docs, removing some TODO information
at the bottom, and moving the license information to CONTRIBUTING.md.
I missed these in my previous doctest PR.
The doctests all now run without accessing the network. Tested by
turning off networking and running them.
Request.call's doctest wouldn't run because it relied on making a custom
AgentBuilder and building it, which bypasses the test_agent. I concluded
that this doctest was mostly illustrating behavior of AgentBuilder, not
call(), and simplified it to be more like the other calling methods on
request.
Doctests run against a normally-built copy of the crate, i.e. one
without #[cfg(test)] set, so we can't use the conditional compilation
feature.
Instead, define a static var that indicates whether the library is
running in test mode or not. For each doctest, insert a hidden call that
sets this var to true. Then, when ureq::agent() is called, it returns a
test_agent instead.
This required moving testserver out of the test mod and into src/, so
that it can be included unconditionally (i.e. when cfg(test) is false).
This PR converts one doctest as an example. If we land this PR, I'll
send a followup to convert the rest.
Instead, rely on Url's built-in query parameter handling. A Request now
accumulates a list of query param pairs, and joins them with a parsed
URL at the time do_call is called.
In the process, remove some getters that rely on parsing the URL.
Adapting these getters was going to be awkward, and they mostly
duplicate things people can readily get by parsing the URL.
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.

Replace `this` idiom with `mut self`.
Move idle connections constants from pool.rs to agent.rs.
Remove Agent.set and some convenience request methods
(leaving get, post, and put).
Move max_idle_connections setting from AgentConfig to AgentBuilder
(since the builder passes these to ConnectionPool and the Agent
doesn't subsequently need them).
Eliminate duplicate copy of proxy in AgentState; use the one in
AgentConfig.
