This fixes a race condition in a test that has been exposed by
CI.
This commit also disables code coverage checks as it has been
causing CI to hang. See #156.
This PR modifies the `Drop` implementation for `StreamRef` to reset the underlying stream if it is the last reference to that stream. Since both `Stream` and `Body` are internally just a `StreamRef`, this means they will both reset the stream on drop; thus, this closes#100.
The assertion that the store no longer contains the dropped stream ID at the end of the `Drop` method had to be removed, as the stream has to be reset from inside of a `transition` block (which now manages releasing that ID for us), and the `transition` closure moves the value of `stream`, making the assertion no longer possible.
Modifications to some of the tests in `flow_control.rs` were also necessary, in order to prevent `StreamRef`s from being dropped too early.
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.
I've rewritten the tests `flow_control::stream_close_by_data_frame_releases_capacity()` and `flow_control::stream_close_by_trailers_frame_releases_capacity()` to use the new mock API. This will make modifying these tests a bit easier in order to expect the correct behavior in my reset-on-drop branch.
When capacity is released back to the connection and a connection level
window update needs to be sent out, the connection task needs to be
notified in order for the send to actually happen.
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.
Senders could set the available capacity greater than the current
`window_size`. This caused a panic when the sender attempted
to send more than the receiver could accept.
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.
