Changes

0.0.7

  • Introduce IO module with low-level IO operations such as performing direct vectorized (or regular) reads/writes. New operations include:

    • read, write

    • single_read, single_write (vectorized)

    • await_readable, await_writeable, await

    • write_all

    • copy and copy_buffered

  • Introduce Buffer module with support for converting from and to CStruct and String, including position tracking.

  • Introduce Read/Reader interface for creating buffered and unbuffered readers of arbitrary sources.

  • Introduce Write/Writer interfaces for creating unbuffered writers into arbitrary destinations/sinks.

  • Introduce File module with Reader and Writer implementations

  • Implment Reader and Writer interfaces for Net.Socket

  • Dropped dependency on Bigstringaf and moved to Cstruct

  • Fix max number of domains to always be under the recommended domain count

  • Fix issue with tests where the runtime idled after the main would die. Now the main process finishing with an exception is considered reason enough to shutdown the system.

  • Refactor tests to always output test_name: OK when everything is fine and all modules to end in _test.

  • Add several IO tests.

  • Fix log levels for writing to sockets

  • Include proper license for C Stubs copied from lib_eio_posix for vectorized i/o.

  • Split test suite into io/non-io so io tests are left outside opam ci

  • Improved IO polling that removes heavy iterations over process/fds tables

  • Rewrite Dashmap internals to use a Hashtbl

0.0.6

  • Redo packaging to expose a single public library: riot

  • Fix issue with schedulers busy-waiting

  • Introduce separate IO Schedulers for polling

  • Switch to poll to support kqueue on macOS

  • Reuse read-buffers on Io.read loops

  • Broaden IO socket types to file descriptors

  • Improved polling with shorter poll timeouts and safety checks

  • Add Dashmap.iter to iterate over a collection

  • Add net_test with an echo tcp server/client

  • Fix bugs with syscall suspension that was introduced with reduction counting

0.0.5

  • Add register name pid

  • Add unregister name

  • Add send_by_name ~name msg

  • Fix timer wheel making it remove timers correctly

  • Add better test for Timer.send_after

0.0.4

  • Internally immediately suspend (bypassing reduction counts) when on a receive expression

  • Fix reads from closed Unix sockets

  • Fix writes to closed Unix sockets

  • Ignore SIGPIPEs on setup

  • Fix always mark connected sockets as nonblocking

  • Fix GC i/o process table

  • Surface pretty-printing of socket values

0.0.3

  • Big namespace refactor. Riot.Runtime includes the lower-level runtime blocks, and everything else that is more user-friendly lives at the Riot.* level.

  • Introduce reduction counting, so processes will run up to N iterations unless they finish, or they execute an unhandled effect.

  • Introduce the Application interface for managing the lifecycle of the system

  • Fix Riot.Logger to fit the Application interface

  • Add a new Riot.Telemetry backend for doing async telemetry

0.0.2

  • New Riot.random () API to expose current scheduler's random state

  • Better logging in the Net module

  • Fix a bug where Net.Socket operations where hanging on I/O polling when they could have been eager

0.0.1

First release, including:

  • First working version of the scheduler

  • Support for process spawning, message passing, monitoring, and linking

  • Rudimentary supervisors

  • Basic (and incomplete) GenServer

  • Scheduling-aware I/O primitives

  • Scheduling-aware Logger

  • Timers
