package riot

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
