[Caml-list] Beta release of OCaml 4.00.0

[Caml-list] Beta release of OCaml 4.00.0

[Damien Doligez]

Dear OCaml users,

The release of OCaml version 4.00.0 is approaching.  We have
created a beta version for your testing pleasure.  Please
download the sources, compile, install, and test your favourite
software with it.  Then let me know what happened, one way or
the other.

We are especially interested in testing done on exotic
architectures (i.e. non-Linux and non-Mac, or 32-bit processors).

This beta version is available as source code at this
address: < http://caml.inria.fr/pub/distrib/ocaml-4.00/ >

The version number is 4.00.0+beta2, note that beta1 was not
released.

Happy hacking,

-- Damien Doligez for the OCaml team.




OCaml 4.00.0:
-------------

(Changes that can break existing programs are marked with a "*")

- The official name of the language is now OCaml.

Language features:
- Added Generalized Abstract Data Types (GADTs) to the language.
  See chapter "Language extensions" of the reference manual for documentation.
- It is now possible to omit type annotations when packing and unpacking
  first-class modules. The type-checker attempts to infer it from the context.
  Using the -principal option guarantees forward compatibility.
- New (module M) and (module M : S) syntax in patterns, for immediate
  unpacking of a first-class module.

Compilers:
- Revised simplification of let-alias (PR#5205, PR#5288)
- Better reporting of compiler version mismatch in .cmi files
* Warning 28 is now enabled by default.
- New option -absname to use absolute paths in error messages
- Optimize away compile-time beta-redexes, e.g. (fun x y -> e) a b.
- Added option -bin-annot to dump the AST with type annotations.
- Added lots of new warnings about unused variables, opens, fields,
  constructors, etc.
* New meaning for warning 7: it is now triggered when a method is overridden
  with the "method" keyword.  Use "method!" to avoid the warning.

Native-code compiler:
- Optimized handling of partially-applied functions (PR#5287)
- Small improvements in code generated for array bounds checks (PR#5345,
  PR#5360).
* New ARM backend (PR#5433):
    . Supports both Linux/EABI (armel) and Linux/EABI+VFPv3 (armhf).
    . Added support for the Thumb-2 instruction set with average code size
      savings of 28%.
    . Added support for position-independent code, natdynlink, profiling and
      exception backtraces.
- In -g mode, generation of CFI information and a few filename/line
  number debugging annotations, enabling in particular precise stack
  backtraces with the gdb debugger. Currently supported for x86 32-bits
  and 64-bits only. (PR#5487)
- New tool: ocamloptp, the equivalent of ocamlcp for the native-code compiler.

OCamldoc:
- PR#5544: improve HTML output (less formatting in html code)
- PR#5522: allow refering to record fields and variant constructors
- fix PR#5419 (error message in french)
- fix PR#5535 (no cross ref to class after dump+load)
* Use first class modules for custom generators, to be able to
  load various plugins incrementally adding features to the current
  generator
* PR#5507: Use Location.t structures for locations.
- fix: do not keep code when not told to keep code.

Standard library:
- Added float functions "hypot" and "copysign" (PR#3806, PR#4752, PR#5246)
* Arg: options with empty doc strings are no longer included in the usage string
  (PR#5437)
- Array: faster implementations of "blit", "copy", "sub", "append" and "concat"
  (PR#2395, PR#2787, PR#4591)
* Hashtbl:
    . Statistically-better generic hash function based on Murmur 3 (PR#5225)
    . Fixed behavior of generic hash function w.r.t. -0.0 and NaN (PR#5222)
    . Added optional "random" parameter to Hashtbl.create to randomize
      collision patterns and improve security (PR#5572, CVE-2012-0839)
    . Added "randomize" function and "R" parameter to OCAMLRUNPARAMS
      to turn randomization on by default (PR#5572, CVE-2012-0839)
    . Added new functorial interface "MakeSeeded" to support randomization
      with user-provided seeded hash functions.
    . Install new header <caml/hash.h> for C code.
- Filename: on-demand (lazy) initialization of the PRNG used by "temp_file".
- Marshal: marshalling of function values (flag Marshal.Closures) now
  also works for functions that come from dynamically-loaded modules (PR#5215)
- Random:
     . More random initialization (Random.self_init()), using /dev/urandom
       when available (e.g. Linux, FreeBSD, MacOS X, Solaris)
     . Faster implementation of Random.float
- Scanf: new function "unescaped" (PR#3888)
- Set and Map: more efficient implementation of "filter" and "partition"
- String: new function "map" (PR#3888)

Installation procedure:
- Compiler internals are now installed in `ocamlc -where`/compiler-libs.
  The files available there include the .cmi interfaces for all compiler
  modules, plus the following libraries:
      ocamlcommon.cma/.cmxa     modules common to ocamlc, ocamlopt, ocaml
      ocamlbytecomp.cma/.cmxa   modules for ocamlc and ocaml
      ocamloptcomp.cma/.cmxa    modules specific to ocamlopt
      ocamltoplevel.cma         modules specific to ocaml
   (PR#1804, PR#4653, frequently-asked feature).
* Some .cmi for toplevel internals that used to be installed in
  `ocamlc -where` are now to be found in  `ocamlc -where`/compiler-libs.
  Add "-I +compiler-libs" where needed.
* toplevellib.cma is no longer installed because subsumed by
  ocamlcommon.cma ocamlbytecomp.cma ocamltoplevel.cma
- Added a configuration option (-with-debug-runtime) to compile and install
  a debug version of the runtime system, and a compiler option
  (-runtime-variant) to select the debug runtime.

Shedding weight:
* Removed the obsolete native-code generators for Alpha, HPPA, IA64 and MIPS.
* The "DBM" library (interface with Unix DBM key-value stores) is no
  longer part of this distribution.  It now lives its own life at
  https://forge.ocamlcore.org/projects/camldbm/
* The "OCamlWin" toplevel user interface for MS Windows is no longer
  part of this distribution.  It now lives its own life at
  https://forge.ocamlcore.org/projects/ocamltopwin/

Other changes:
- Copy VERSION file to library directory when installing.

I can confirm that 4.00.0 no longer works on MIPS.

Pain is aleviated by the realization that the venerable Sparc did survive the
purge, though, for some obscure reason.

Great job! 

> - PR#5437: warning for useless open statements

Maybe this is actually PR#5357? PR#5437 is "Patch to allow command line
arguments in Arg module to be undocumented".

I'm now maintaining an out-of-tree ppc64 backend (note: not Rhapsody,
this is for IBM POWER and Linux on Mac G5s).  In fact I fixed two bugs
in it just today.

http://git.fedorahosted.org/git/?p=fedora-ocaml.git

If someone wants to pull together all the out-of-tree backends into
one place, let me know.  I'm sort of interested in maintaining the
dropped Itanic backend too, since customers will insist on using it
for some reason.

For people interrested MIPS support is back in, there:

http://github.com/rixed/ocaml-4-for-mips

It was pretty easy, since almost nothing had changed in the backend.
So it was perhaps more work required to remove mips support than to
reintroduce it. :-/

Well, I'm not particularly fan of github nor gitorious neither, but both have
good support for git (ie pull requests and online diffs), have a wiki, support
team work, and are well known. Github being more popular I'd also go for it
despite being non free. But if you have a better option I don't really care.

Which RichardJones are you on github? this one:
https://github.com/richard-jones
or rather this one:
https://github.com/RichardJones
??

Also, does anybody know of an up-to-date git mirror for the OCaml source tree?
(yeah this is becoming a F.A.Q). I've seen these:

https://github.com/bmeurer/ocaml
https://github.com/thelema/ocaml-community (not many branches)
https://github.com/multani/ocaml-mirror (not the same branches as bmeurer ones)
https://github.com/OCamlPro/ocaml-testing (not up to date)

but there are a surprising lot of projects related to ocaml in github, which
I'm not going to complain about, but so I might be missing some.

So should we create the `retired-camels` team and fork Benedikt's mirror to
begin with?

Unfortunately, all these repos are incompatible, in the sense that there 
is no common commit in their histories ("git svn" creates new commit ids 
every time you create a new checkout from the same svn repo, in my 
experience).

I am not an expert of "git", but can somebody tell me if it is possible 
to "git svn rebase" a fork of Benedikt's mirror, or if only Benedikt can 
do it ?

I remember using "git svn" at some point, and being surprised that the 
svn synchronisation stuff was not saved in the git repository, so that I 
was unable to re-sync from a clone of that repository, I had to do it 
always from the initially created git repo. But maybe --mirror fixes 
that ? (I didn't use it at that time)

There is a github.com/ocaml account which was reserved by them a few years ago. I've sent them a support request to find out if we can get access to it to setup an authoritative mirror from the SVN repository.  That would be much more preferable than individual svn-to-gits...

Neither ... this one:

Here is the current ppc64 backend, rebased against OCaml 4.00.0 beta2
yesterday:

  http://git.fedorahosted.org/git/?p=fedora-ocaml.git

The top two commits there are both needed to make ppc64 work, but note
that the second commit is a general OCaml fix (PR#5636).

Ok so I've just created the retired-camels organization in github,
with a fork of Benedikt mirror, and then cherry picked the two
commits you mentioned above the 4.00 branch (in a branch named
ppc64). I've done as well with the mips commits.

Could you please check that this ppc64 branch works on ppc64?
I will check as well the mips branch in a few days. When both are
OK we should merge them into a a 'more-arch' branch that we'll
just have to rebase regularly, until a better solution emerge.

Will do later.  Note that the -lpthread patch has just been
accepted & committed upstream.

The first failure I got is from oUnit setup.ml which attempt to
scanf "%S %S@\n", but using the @ after a %S (not %s) does not
work the same as in 3.12.1 : it looks for a '@' instead of interpreting
it as a scanning indication.
The manual says that scanning indications are for %s and %[range],
so it seams setup.ml is to blame, though.

I just discovered the same problem.  Unfortunately ounit is a build
requirement for many OCaml packages, so this blocks a large part of
the rebuild.

Is this an OCaml bug, or just a change in functionality?  Has a Mantis
report been filed?

OASIS 0.3.0~rc6 should have a fix for this, quoting from its CHANGES.txt:
" * Version 0.3.0

  * EXTREMLY IMPORTANT changes (read this):

    * Fix bug with scanf %S@\n for ocaml 3.13. We were unfortunetaly using an
      undocumented tolerance of Scanf in the previous version. You should
      consider making new release using this version that fixed this."

I can confirm this issue is fixed in the current version of oasis. Note
that all packages using oasis should be updated as soon as possible
(preferably before ocaml 4.00 is released and widely included in
linux/macos distros), otherwise I fear we'll be hearing about that scanf
bug for a looong time.

In particular, all packages on oasis-db should be taken care of rapidly, as
they are used by odb. Maybe we could organize a bit so that this is done
collaboratively *and* efficiently?

A beta version of the reference manual is not available at
the same address.
