Upgrade to env_logger 0.5 and log 0.4 so that projects that use those
versions don't have to build both those versions and the older ones
that h2 is currently using.
Don't enable the regex support in env_logger. Applications that want
the regex support can enable it themselves; this will happen
automatically when they add their env_logger dependency.
Disable the env_logger dependency in quickcheck.
The result of this is that there are fewer dependencies. For example,
regex and its dependencies are no longer required at all, as can be
seen by observing the changes to the Cargo.lock. That said,
env_logger 0.5 does add more dependencies itself; however it seems
applications are going to use env_logger 0.5 anyway so this is still
a net gain.

When all Streams are dropped / finished, the Connection was held
open until the peer hangs up. Instead, the Connection should hang up
once it knows that nothing more will be sent.
To fix this, we notify the Connection when a stream is no longer
referenced. On the Connection poll(), we check that there are no
active, held, reset streams or any references to the Streams
and transition to sending a GOAWAY if that is case.
The specific behavior depends on if running as a client or server.
This patch renames a number of types and functions making
the API more consistent.
* `Server` -> `Connection`
* `Client` -> `SendRequest`
* `Respond` -> `SendResponse`.
It also moves the handshake fns off of `Connection` and make
them free fns in the module. And `Connection::builder` is removed
in favor of `Builder::new`.
As requested in https://github.com/carllerche/h2/issues/38#issuecomment-328254128, I've added a test to `stream_states.rs` to cover the case where we receive a HEADERS frame that gets rejected (due to being malformed), then the same stream ID is received with a valid HEADERS frame which gets accepted.
Closes#38
This function returns true if the `RecvStream` has reached an end of
stream state. This is intended to replace `is_empty` which has confusing
behavior.
The Connection type is a `Future` that drives all of the IO of the
client connection.
The Client type is separate, and is used to send requests into the
connection.
- Adds `max_frame_size` to client and server builders
- Pushes max_frame_size into Codec
- Detects when the Codec triggers an error from a frame too big
- Sends a GOAWAY when FRAME_SIZE_ERROR is encountered reading a frame
This change adds a .rustfmt.toml that includes ALL supported settings,
12 of which we have overridden to attempt to cater to our own
proclivities.
rustfmt is checked in the rust-nightly CI job.
Previously, stream state was never released so that long-lived connections
leaked memory.
Now, stream states are reference-counted and freed from the stream slab
when complete. Locally reset streams are retained so that received frames
may be ignored.
Restructure send flow control such that sending data is always accepted by `Stream`. Data frames will be buffered until there is available window to send them. Producers can monitor the available window capacity to decide if data should be produced.
