OCaml 4.11.0 released

I have the pleasure of announcing the release of OCaml version 4.11.0,
dedicated to the memory of Blaise Pascal on the anniversary of his death.

Some of the highlights in this release are:

  • Statmemprof: a new statistical memory profiler
  • A new instrumented runtime that logs runtime statistics in a standard format
  • A native backend for the RISC-V architecture
  • Improved backtraces that refer to function names
  • Support for recursive and yet unboxed types
  • A quoted extension syntax for ppxs.
  • Many quality of life improvements
  • Many bug fixes.

The full list of change can be found in the changelog below:


OCaml 4.11.0 (19 August 2020)

(Changes that can break existing programs are marked with a “*breaking change” warning)

Runtime system:

  • #9096: Print function names in backtraces.
    Old output:

    Called from file “foo.ml”, line 16, characters 42-53

    New output:

    Called from Foo.bar in file “foo.ml”, line 16, characters 42-53

    (Stephen Dolan, review by Leo White and Mark Shinwell)

  • #9082: The instrumented runtime now records logs in the CTF format.
    A new API is available in the runtime to collect runtime statistics,
    replacing the previous instrumented runtime macros.
    Gc.eventlog_pause and Gc.eventlog_resume were added to allow user to control
    instrumentation in a running program.
    See the manual for more information on how to use this instrumentation mode.

    David Allsopp, SĂ©bastien Hinderer, review by Anil Madhavapeddy,
    NicolĂĄs Ojeda BĂ€r, Shakthi Kannan, KC Sivaramakrishnan, Gabriel Scherer,
    Guillaume Munch-Maccagnoni, Damien Doligez, Leo White, Daniel BĂŒnzli
    and Xavier Leroy)

  • #9230, #9362: Memprof support for native allocations.
    (Jacques-Henri Jourdan and Stephen Dolan, review by Gabriel Scherer)

  • #8920, #9238, #9239, #9254, #9458: New API for statistical memory profiling
    in Memprof.Gc. The new version does no longer use ephemerons and allows
    registering callbacks for promotion and deallocation of memory
    blocks.
    The new API no longer gives the block tags to the allocation callback.
    (Stephen Dolan and Jacques-Henri Jourdan, review by Damien Doligez
    and Gabriel Scherer)

  • #9353: Reimplement output_value and the Marshal.to_* functions
    using a hash table to detect sharing, instead of temporary in-place
    modifications. This is a prerequisite for Multicore OCaml.
    (Xavier Leroy and Basile Clément, review by Gabriel Scherer and
    Stephen Dolan)

  • #9119: Make [caml_stat_resize_noexc] compatible with the [realloc]
    API when the old block is NULL.
    (Jacques-Henri Jourdan, review by Xavier Leroy)

  • #9233: Restore the bytecode stack after an allocation.
    (Stephen Dolan, review by Gabriel Scherer and Jacques-Henri Jourdan)

  • #9249: restore definition of ARCH_ALIGN_INT64 in m.h if the architecture
    requires 64-bit integers to be double-word aligned (autoconf regression)
    (David Allsopp, review by SĂ©bastien Hinderer)

  • #9259: Made Ephemeron.blit_key and Weak.blit faster. They are now
    linear in the size of the range being copied instead of depending on the
    total sizes of the ephemerons or weak arrays involved.
    (Arseniy Alekseyev, design advice by Leo White, review by François Bobot
    and Damien Doligez)

  • #9279: Memprof optimisation.

    recursive module initialisation in one particular case (fixes #9494).
    (Mark Shinwell, David Allsopp, Vincent Laviron, Xavier Leroy,
    Geoff Reedy, original bug report by Arlen Cox)

  • #8791: use a variable-length encoding when marshalling bigarray dimensions,
    avoiding overflow.
    (Jeremy Yallop, Stephen Dolan, review by Xavier Leroy)

Code generation and optimizations:

  • #9441: Add RISC-V RV64G native-code backend.
    (NicolĂĄs Ojeda BĂ€r, review by Xavier Leroy and Gabriel Scherer)

  • #9316, #9443, #9463, #9782: Use typing information from Clambda
    for mutable Cmm variables.
    (Stephen Dolan, review by Vincent Laviron, Guillaume Bury, Xavier Leroy,
    and Gabriel Scherer; temporary bug report by Richard Jones)

  • #8637, #8805, #9247, #9296: Record debug info for each allocation.

    (David Allsopp, report by Nathaniel Wesley Filardo, review by Xavier Leroy)

Language features

  • #8820, #9166: quoted extensions: {%foo|
|} is lighter syntax for
    [%foo {||}], and {%foo bar|
|bar} for [%foo {bar|
|bar}].
    (Gabriel Radanne, Leo White, Gabriel Scherer and Pieter Goetschalckx,
    request by Bikal Lem)

  • #7364, #2188, #9592, #9609: improvement of the unboxability check for types
    with a single constructor. Mutually-recursive type declarations can
    now contain unboxed types. This is based on the paper

    for extensible sum type constructors
    (Florian Angeletti, review by Alain Frisch, Gabriel Radanne, Gabriel Scherer
    and Leo White)

  • #6673, #1132, #9617: Relax the handling of explicit polymorphic types.
    This improves error messages in some polymorphic recursive definition,
    and requires less polymorphic annotations in some cases of
    mutually-recursive definitions involving polymorphic recursion.
    (Leo White, review by Jacques Garrigue and Gabriel Scherer)

    SĂ©bastien Hinderer, and David Allsopp)

  • #9237: Format.pp_update_geometry ppf (fun geo -> {geo with ...})
    for formatter geometry changes that are robust to new geometry fields.
    (Gabriel Scherer, review by Josh Berdine and Florian Angeletti)

  • #7110: Added Printf.ikbprintf and Printf.ibprintf
    (Muskan Garg, review by Gabriel Scherer and Florian Angeletti)

    of dynlinked modules.
    (NicolĂĄs Ojeda BĂ€r, review by Xavier Clerc and Gabriel Scherer)

  • #9320, #9550: under Windows, make sure that the Unix.exec* functions
    properly quote their argument lists.
    (Xavier Leroy, report by André Maroneze, review by Nicolås Ojeda BÀr
    and David Allsopp)

  • #9490, #9505: ensure proper rounding of file times returned by
    Unix.stat, Unix.lstat, Unix.fstat.
    (Xavier Leroy and Guillaume Melquiond, report by David Brown,
    review by Gabriel Scherer and David Allsopp)

Tools:

  • #9283, #9455, #9457: add a new toplevel directive #use_output "<command>" to
    run a command and evaluate its output.
    (Jérémie Dimino, review by David Allsopp)

  • #6969: Argument -nocwd added to ocamldep
    (Muskan Garg, review by Florian Angeletti)

  • #8676, #9594: turn debugger off in programs launched by the program

  • #9181: make objinfo work on Cygwin and look for the caml_plugin_header
    symbol in both the static and the dynamic symbol tables.
    (SĂ©bastien Hinderer, review by Gabriel Scherer and David Allsopp)

  • [breaking change] #9197: remove compatibility logic from #244 that was designed to
    synchronize toplevel printing margins with Format.std_formatter,
    but also resulted in unpredictable/fragile changes to formatter
    margins.
    Setting the margins on the desired formatters should now work.
    typically on Format.std_formatter.
    Note that there currently is no robust way to do this from the
    toplevel, as applications may redirect toplevel printing. In
    a compiler/toplevel driver, one should instead access
    Location.formatter_for_warnings; it is not currently exposed
    to the toplevel.
    (Gabriel Scherer, review by Armaël Guéneau)

    (Stephen Dolan, review by Florian Angeletti, report by Hannes Mehnert)

Compiler user-interface and warnings:

  • #9712: Update the version format to allow “~”.
    The new format is “major.minor[.patchlevel][(+|~)additional-info]”,
    for instance “4.12.0~beta1+flambda”.
    This is a documentation-only change for the 4.11 branch, the new format
    will be used starting with the 4.12 branch.

https://ocaml.org/releases/4.11.0.html is linked in several places on ocaml.org (eg https://ocaml.org/docs/install.html “For more information about this release, see the 4.11.0 page.”) but it’s a 404

The site ocaml.org has not been updated yet, but this should be fixed soon.

A bit unrelated, but I noticed how times of Travis CI job build times are decreasing with the newer OCaml versions for the same package. For example, the ppx_deriving_protobuf today:

Always good to see such an improvements :+1:
