This commit changes the `PollEvented::deregister` signature from
fn deregister(self, handle: &Handle) -> io::Result<()>
to
fn deregister(&self) -> io::Result<()>
Now that the handles are `Send` and `Sync` there's no longer any need to pass it
in (it's already stored in the `PollEvented` itself). Additionally this switches
to `&self` instead of `self` to allow reclamation of the internal resources if
necessary.
This should allow configuration over what reactor accepted streams go on to by
giving back a libstd-bound object that can then be used later in conjunction
with `TcpStream::from_std`.
This commit is targeted at solving tokio-rs/tokio-core#12 and incorporates the
solution from tokio-rs/tokio-core#17. Namely the `need_read` and `need_write`
functions on `PollEvented` now return an error when the connected reactor has
gone away and the task cannot be blocked. This will typically naturally
translate to errors being returned by various connected I/O objects and should
help tear down the world in a clean-ish fashion.
This commit renames the various constructors of networking types to have a
`_std` suffix instead of a smorgasboard of other suffixes, canonicalizing on
`_std` as the suffix for constructors which take the libstd corresponding types.
* small doc cleanups in PollEvented
* small doc cleanups in IoToken
* improve crate level documentation
- Add links to the futures, mio and tokio-uds crates.
- Add links to various structs and types mentioned.
- use eprintln for error reporting in the example.
* improvements to the UdpSocket documentation
- Fixed links usage.
- Removed references to a no longer existing `Window` struct.
- Made notes about using functions in context of a future.
* documentation improvements to UdpFramed and UdpCodec
- Since HTTP uses TCP (QUIC aside) using it as an example in an UDP
protocol feels wrong.
- Make the note of tampering with the underlying streams more explicit.
* update reactor module level documentation
Adds an explanation of every public struct.
* expand Handle and Remote documentation
* expand net module documentation
Adds an explanation of every public struct and how they work together.
* update TcpListener documentation
Reorder the various option methods; get first then set.
Note about panicing added to poll_read.
* remove mention of none-existing future R
* improve documentation of TcpStream
* fix UdpSocket doc
This when wrong when merging various commits.
* Make Handle `Send + Sync`.
This is an initial implementation making `Handle: Send + Sync`. It uses
a `RwLock` to coordinate access to the underlying state storage. An
implementation without the lock is left to later.
This pass also leaves a lot of dead code that can be removed in later
commits.
* Remove reactor code related to message passing
The previous commit removed the need for using message passing to
communicate with the reactor. This commit removes all the unnecessary
code.
In accordance with tokio-rs/tokio-rfcs#3, the executor functionality of
Tokio is being removed and will be relocated into futures-rs as a
"current thread" executor.
This PR removes task execution from the code base. As a temporary
mesure, all examples and tests are switched to using CpuPool.
Depends on #19.
In accordance with tokio-rs/tokio-rfcs#3, timers are being extracted
from Tokio and moved to a separate crate (probably futures-timer).
This PR removes timers from the code base.
Some contexts, like EC2, have `Instant::now` as a relatively expensive function
to call. To help amortize the cost of this function this commit exposes a new
function on `Interval` and `Timeout` to pass in the assumed current time.
The `consume_queue` function can be relatively slow for an empty queue (the fast
path) so optimize this a bit with a preflight check that should just touch a few
atomics.
My slab bump in #246 added a potential new panic in Core's Inner's
`cancel_timeout`.
Thankfully, the only way `cancel_timeout` can be called is from
TimeoutToken's `cancel_timeout`, which is crate-internal only and is
only called from Timeout's and Interval's drop fn's.
This change simply adds new clarifying documentation around
TokenTimeout's cancel_timeout to "future proof" anybody looking to use
cancel_timeout directly (not just on drop).
This patch disables various Unix-specific platform features that are
not enabled on Fuchsia. It also updates the mio version to 0.6.10,
which is the first release that supports Fuchsia.
