0.11

CHANGES:

New features / API changes:

• Extend Eio.Condition API (@talex5 #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 #560, reviewed by @talex5).
  Useful in tests to report which backend is being used.

• Remove deprecated features (@talex5 #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 #547, requested by @anmonteiro, reviewed by @patricoferris, @avsm).

• Add close to socket type (@talex5 #549).
  Simplifies the type signatures a bit by avoiding having to mention this everywhere.

Bug fixes:

• Fix handling of empty path strings (@talex5 #569, reported by @SGrondin).
  Using "" instead of "." in some places resulted in an error.

• eio_posix: fix update to watched FDs on cancel (@talex5 #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 #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 #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 #571).
  See ocaml/ocaml#12362.

• Correct the backend selection for Cygwin (@dra27 #557).
  Use eio_posix, not eio_windows in this case.

Other changes:

• Simplify dune files with dune 3.9's build_if (@talex5 #582).

• Remove Waiters from Eio_core (@talex5 #567).
  Eio.Switch no longer uses this so it can finally be removed.

• Use Fmt.Dump.signal to format signals (@talex5, @MisterDA #543).

Documentation:

• Add some notes about thread-safety in the documentation (@talex5 #568).
