0.3.3 2018-08-28

  • update to libuv 1.23.0:

    • new functions: Uwt.Misc.setpriority, Uwt.Misc.getpriority, and Uwt.Misc.getpid. (Unix.getpid doesn't return GetCurrentProcessID under Windows ...)

  • fix compilation

0.3.2 2018-07-16

  • update to libuv 1.22.0:

    • new function: Uwt.Fs.lchmown

  • Change license to MIT

  • fix compilation under OCaml 4.07.0 (Windows)

  • add new Uwt.error codes: EHOSTDOWN, EREMOTEIO, ENOTTY, and EFTYPE

0.3.0.2 2018-04-23

Maintenance release, because the bundled libuv version of the previous release contains a serious regression.

  • update to libuv 1.20.2

  • File related functions inside Uwt_compat.Lwt_io now take parameters of type Unix.open_flag instead of Uwt.Fs.uv_open_flag

0.3.0 2018-04-15

  • update to lwt 4.0.0:

    • The modules Uwt_chan and Uwt_log have been removed. Uwt_log is available as an external library
    • Uwt_io.file_length now fails with EISDIR when used on a directory (see ocsigen/lwt#563)

  • update to libuv 1.20.0:

    • Uwt.Fs.copyfile now supports file cloning

0.2.4 2018-02-10

  • fix compilation under OCaml 4.06.0 (Windows)

  • update to libuv 1.19.1:

    • new flags for Uwt.Fs.openfile: O_DIRECT, O_EXLOCK, O_NOATIME, O_SYMLINK, O_NOFOLLOW, and O_DIRECTORY
    • new function: Uwt.Pipe.chmod to allow access from other users
    • new function: Uwt.Misc.getppid (similar to Unix.getppid, but also supported under Windows).

0.2.3 2017-09-08

  • update to libuv 1.14.1

  • new functions from Lwt_io: Uwt_io.open_temp_file and Uwt_io.with_temp_file

  • Uwt_base.Sys_info.win_version now reports your current Windows version, even if your executable is not manifested.

0.2.2 2017-08-17

  • update to libuv 1.14.0:

    • new function: Uwt.Fs.copyfile
    • Uwt.Poll.start now supports watching for sysfs interrupts or TCP out-of-band messages
    • Uwt.Udp.try_send now works under Windows

  • Uwt.Tcp.enable_keepalive will now fail, if you pass an Uwt.Tcp.t handle to it, that doesn't wrap a socket yet. libuv silently ignores the delay parameter in this case. You can use Uwt.Tcp.init_ipv4 or Uwt.Tcp.init_ipv6 instead of Uwt.Tcp.init to circumvent this problem.

  • Uwt_io and Uwt_log have been updated to match the recent lwt.unix changes.

0.2.1 2017-06-01

  • update internal libuv version to to 1.12.0
    • new functions: Uwt.Signal.oneshot and Uwt_base.Misc.{put,set,unset}env (added because of utf8 support under windows)

0.2.0 2017-12-05

  • Uwt.Misc.guess_handle now takes an Unix.file_descr as parameter (instead of Uwt.file). This doesn't follow the libuv prototypes, but makes more sense in the OCaml context. Uwt.Misc.guess_handle can also classify UDP and TCP sockets on Windows.

  • The IPC interface has changed:

    • Uwt.Stream.write2 has been removed. There are now properly typed Uwt.Pipe.write2* functions that can also send UDP handles to a child process.
    • Uwt.Stream.accept_raw has been removed. Instead Uwt.Pipe.accept_ipc must be used to accept handles that were send via the libuv specific IPC interface. Uwt.Tcp.accept_raw and Uwt.Pipe.accept_raw still exist.
    • The Uwt.Process.stdio type has been extended. Uwt.Process.spawn now allows to create duplex stream for IPC (previously not exposed by uwt)

  • Exception update: Many functions Lwt.fail with exception Unix_error of error * string * string (or the foo_exn functions will raise such exceptions). The first string component of this exception is supposed to contain the function name. However there was no consistency what was put there as name. If the function is called uv_foo (or uv_xy_foo, uv_foo_xy, etc.) and man 2 foo or man 3 foo lists a closely related function that could be wrapped by uv_foo, foo is used as function name (even if a different, system dependent function is used internally by libuv). This leads to more consistent behaviour regarding to Unix and Lwt_unix. If it's not obvious (by just looking at the name), which function is called by libuv, uv_foo is used instead.

  • new functions: Uwt.Fs.pread / Uwt.Fs.pwrite / Uwt.Fs.pwritev

  • The mli files are now better documented.

  • Uwt.Tcp.keepalive has been split in two functions: Uwt.Tcp.enable_keepalive and Uwt.Tcp.disable_keepalive

  • Tasks that are intended to run in libuv's threadpool and are canceled via Lwt.cancel now report the success of the cancellation immediately instead of slightly deferred. So the following check will work now:

    let s = Uwt.Fs.stat "foo" in
(* more code *)
assert (Lwt.state s = Lwt.Sleep); (* relevant use case *)
Lwt.cancel s;
match Lwt.state s with
| Lwt.Sleep -> print_endline "cancel failed, the job is already running in background"
| Lwt.Fail Lwt.Canceled -> print_endline "cancel success"
| _ -> prerr_endline "Huh?"```

  • Bugs in the following functions have been fixed:

    • Uwt.Udp.set_multicast_ttl (it rejected valid parameters)
    • Uwt.Handle_ext.get_send_buffer_size / Uwt.Handle_ext.get_recv_buffer_size (they've returned wrong results)
    • Uwt.Stream.write2 (now ``Uwt.Pipe.write2`) (invalid memory access under Windows, because libuv's interface slightly differs on windows and unix)

0.1.0 2017-03-02

  • new functions: Uwt.Stream.writev and Uwt.Fs.writev

  • the opam package will now always use the internal copy of libuv.

  • prepare OCaml 4.05 support

  • internal libuv version updated to 1.11.0

  • avoid memcpy calls inside Uwt.Stream.read and Uwt.Udp.recv (*nix only)

  • Set up Travis for OS X testing

0.0.4 2016-11-04

  • API CHANGE: Uwt_error removed. Functions that possibly fail with no-unix error codes will now always return ('a, Uwt.error) result Lwt.t, all other functions will Lwt.fail with Unix_error. Unix.ECANCELED is unfortunately missing, you have to use Uwt.of_unix_error x = Uwt.ECANCELED instead.

  • uwt now compiles with Microsoft Visual Studio (14.0 only)

  • internal libuv version updated to 1.10.0

  • update lwt.unix compatibility layer
