CHANGES: New features / API changes: - Extend `Eio.Condition` API (@talex5 ocaml-multicore/eio#563). - `loop_no_mutex` is a simpler and more efficient way to way for a condition. - `register_immediate` allows integration with other IO libraries. - Expose `Eio.Stdenv.backend_id` (@bord-o ocaml-multicore/eio#560, reviewed by @talex5). Useful in tests to report which backend is being used. - Remove deprecated features (@talex5 ocaml-multicore/eio#552, reviewed by @avsm). These were all already marked as deprecated in v0.10 and are now gone completely: - `Fiber.fork_sub` - `Eio_unix.{FD,Ipaddr,socketpair,getnameinfo}` - `Eio_linux.{FD,get_fd,get_fd_opt}` - `Eio_posix.Low_level.Fd` - Allow calling `close` more than once (@talex5 ocaml-multicore/eio#547, requested by @anmonteiro, reviewed by @patricoferris, @avsm). - Add `close` to socket type (@talex5 ocaml-multicore/eio#549). Simplifies the type signatures a bit by avoiding having to mention this everywhere. Bug fixes: - Fix handling of empty path strings (@talex5 ocaml-multicore/eio#569, reported by @SGrondin). Using "" instead of "." in some places resulted in an error. - eio_posix: fix update to watched FDs on cancel (@talex5 ocaml-multicore/eio#574, reported and reviewed by @quernd). Cancelling the last watcher of an FD didn't remove it from the set passed to `poll`, which could result in constant wake-ups. - eio_posix: fix `pread` at end-of-file (@talex5 ocaml-multicore/eio#581, reported by @SGrondin). It tried to return 0 instead of `End_of_file`, triggering an assertion. - eio_posix: don't reap non-Eio child processes (@talex5 ocaml-multicore/eio#562). This allows spawning processes with e.g. the stdlib or Lwt (but see ocaml-multicore/lwt_eio#19 for Lwt support). - Preserve backtraces across `Domain_manager.run` (@talex5 ocaml-multicore/eio#571). See ocaml/ocaml#12362. - Correct the backend selection for Cygwin (@dra27 ocaml-multicore/eio#557). Use `eio_posix`, not `eio_windows` in this case. Other changes: - Simplify dune files with dune 3.9's `build_if` (@talex5 ocaml-multicore/eio#582). - Remove `Waiters` from `Eio_core` (@talex5 ocaml-multicore/eio#567). `Eio.Switch` no longer uses this so it can finally be removed. - Use `Fmt.Dump.signal` to format signals (@talex5, @MisterDA ocaml-multicore/eio#543). Documentation: - Add some notes about thread-safety in the documentation (@talex5 ocaml-multicore/eio#568).
