Deprecations

  • Lwt_main.yield and Lwt_unix.yield are deprecated in favor of the generic Lwt.pause, and Lwt_unix.auto_yield is deprecated in favor of the new Lwt_unix.auto_pause. Currently, Lwt_main.run resolves paused promises more frequently than yielded promises; the difference is unintended but existing applications could unintentionally depend on it. (#855, #858, Favonia)

Fixes

  • Use is_blocking in dup and dup2 to fix ENOTSOCK on Windows. (#869, Antonin Décimo)

  • Lwt_unix.lstat was incorrectly calling Unix.stat on Win32. Fixes the behavior of Lwt_io.with_temp_dir following symlinks to directories on Win32. (#883, Antonin Décimo)

  • Support deleting symlinks on Windows during cleanup of Lwt_io.with_temp_dir. (#886, Antonin Décimo)

  • Lwt_react.S.l[2-6]_s used polymorphic equality which could cause errors when handling functional values. (#893, Jérôme Vouillon)

  • On Windows, treat ERROR_BROKEN_PIPE on read as zero-read instead of error. See OCaml PR #4790. (#898, Antonin Décimo)

  • Fix compilation under MSVC by replacing Noreturn with CAMLnoreturn. (#880, #887, Nicolás Ojeda Bär)

Additions

  • Lwt_bytes.blit_from_string: string complement of Lwt_bytes.blit. (#882, Hugo Heuzard)

  • Lwt_seq: a Seq-like data-structure with Lwt delayed nodes. (#836, #842, Zach Shipko)

  • Lwt_unix.auto_pause: the replacement of Lwt_unix.auto_yield that uses Lwt.pause instead of Lwt_unix.yield. (#855, #858, Favonia)

  • Lwt_stream.return, Lwt_stream.return_lwt: singleton stream constructors. (#864, Boning Dong)

  • Add ?to_dir param from Unix.symlink to Lwt_unix.symlink wrapper. (#884, Antonin Décimo)

  • Lwt_stream.of_lwt_seq to convert an Lwt-sequence into an Lwt-stream. (#873)

  • Support IPv6 (always) and PF_UNIX (with OCaml >= 4.14) socketpair on Windows. (#870, #876, Antonin Décimo, David Allsopp)

  • In the Lwt_unix module, add ?cloexec:bool optional arguments to functions that create file descriptors (dup, dup2, pipe, pipe_in, pipe_out, socket, socketpair, accept, accept_n). The ?cloexec argument is simply forwarded to the wrapped Unix function (with OCaml >= 4.05, see PR ocaml/ocaml#650), or emulated as best-effort with Unix.set_close_on_exec on older OCaml versions. (#327, #847, #872, #901, Antonin Décimo)

  • Lwt_domain: helpers for using domainslib from Lwt. (#860, Sudha Parimala)

Misc

  • Code quality improvement: remove an unneeded Obj.magic. (#844, Benoit Montagu)

  • On Windows, use the Unicode API in C stubs and functions introduced in OCaml 4.06 to handle Unicode strings. Raise the minimum requirement to OCaml 4.06 (on Windows only). (#843, #903, Antonin Décimo)

  • More complete coverage in the CI. (#890, #894, #896, Sora Morimoto)

  • Code quality improvement: use exception pattern instead of try-with. (#895, Antonin Décimo)

  • Code quality improvement: fix warnings on 4.13. (#899)
