OCaml 4.04.0:

|
-------------
|
|
|
|
(Changes that can break existing programs are marked with a "*")
|
|
|
|
Build system:
|
|
- GPR#324: Compiler developpers only: Adding new primitives to the
|
|
standard runtime doesn't require anymore to run `make bootstrap`
|
|
(François Bobot)
|
|
- GPR#384: Fix compilation using old Microsoft C Compilers not
|
|
supporting secure CRT functions (SDK Visual Studio 2005 compiler and
|
|
earlier) and standard 64-bit integer literals (Visual Studio .NET
|
|
2002 and earlier) (David Allsopp)

OCaml 4.03.0:
|
|
-------------
|
|
|
|
(Changes that can break existing programs are marked with a "*")
|
|
|
|
Language features:
|
|
- PR#5528: inline records for constructor arguments
|
|
(Alain Frisch)
|
|
- PR#6220, PR#6403, PR#6437, PR#6801:
|
|
Improved redundancy and exhaustiveness checks for GADTs.
|
|
Namely, the redundancy checker now checks whether the uncovered pattern
|
|
of the pattern is actually inhabited, exploding at most one wild card.
|
|
This is also done for exhaustiveness when there is only one case.
|
|
Additionally, one can now write unreachable cases, of the form
|
|
"pat -> .", which are treated by the redundancy check.
|
|

- PR#6374: allow "_ t" as a short-hand for "(_, _, ..) t" for n-ary type
|
|
constructors
|

(Alain Frisch)
|

- PR#6714: allow [@@ocaml.warning] on most structure and signature items:
|
|
values, modules, module types
|
|
(whitequark)
|
|
- PR#6806: Syntax shortcut for putting a type annotation on a record field:
|
|
{ f1 : typ = e } is sugar for { f1 = (e : typ) }
|
|
{ f1 : typ } is sugar for { f1 = (f1 : typ) }
|
|
(Valentin Gatien-Baron, review by Jérémie Dimino)

- GPR#42: short functor type syntax: "S -> T" for "functor (_ : S) -> T"
|
|
(Leo White)
|
|
- GPR#88: allow field punning in object copying expressions:

|
{< x; y; >} is sugar for {< x = x; y = y; >}

|
|
"Make it \o033[1mBOLD\o033[0m"
|
|
(Rafaël Bocquet, request by John Whitingthon)
|
|
- GPR#167: allow to annotate externals' arguments and result types so
|
|
they can be unboxed or untagged: [@unboxed], [@untagged]. Supports
|
|
untagging int and unboxing int32, int64, nativeint and float.
|
|
(Jérémie Dimino, Mark Shinwell)
|
|
- GPR#173: [@inline] and [@inlined] attributes (for function declarations
|
|
and call sites respectively) to control inlining
|
|
(Pierre Chambart, Mark Shinwell)
|
|
- GPR#188: accept [@@immediate] attribute on type declarations to mark types
|
|
that are represented at runtime by an integer
|
|
(Will Crichton, reviewed by Leo White)
|
|
* GPR#234: allow "[]" as a user-defined constructor. Demand parenthesis
|
|
around "::" when using "::" as user-defined constructor:
|
|
code using "| :: of ..." must change to "| (::) of ...".
|
|
(Runhang Li, review by Damien Doligez)
|
|
- GPR#240: replace special annotations on externals by attributes:
|
|
* "float" is generalized to [@@unboxed]
|
|
* "noalloc" becomes [@@noalloc]
|
|
Deprecate "float" and "noalloc".
|
|
(Jérémie Dimino)
|
|
- GPR#254: @ocaml.warn_on_literal_pattern attribute on constructors to
|
|
warn when the argument is matches against a constant pattern. This
|
|
attribute is applied on predefined exception constructors which
|
|
carry purely informational (with no stability guarantee) message.
|
|
(Alain Frisch)
|
|
- GPR#268: hexadecimal notation for floating-point literals: -0x1.ffffp+987
|
|
In OCaml source code, FP literals can be written using the hexadecimal
|
|
notation 0x<mantissa in hex>p<exponent> from ISO C99.
|
|
(Xavier Leroy)
|
|
- GPR#273: allow to get the extension slot of an extension constructor
|
|
by writing [%extension_constructor <path>]
|
|
(Jérémie Dimino)
|
|
- GPR#282: change short-paths penalty heuristic to assign the same cost to
|
|
idents containing double underscores as to idents starting with an underscore
|
|
(Thomas Refis, Leo White)
|
|
- PR#6681 GPR#326: signature items are now accepted as payloads for
|
|
extension and attributes, using the syntax [%foo: SIG ] or [@foo: SIG ].
|
|
Examples: "[%%client: val foo : int]" or "val%client foo : int".
|
|
(Alain Frisch and Gabriel Radanne)
|
|
* GPR#342: Allow shortcuts for extension and attributes on all keywords:
|
|
module%foo, class[@foo], etc.
|
|
The attribute in "let[@foo] .. in .." is now attached to the value binding,
|
|
not to the expression.
|

Compilers:
|
|
- PR#4080, PR#6537, PR#5333: fix stack overflow in the compiler
|
|
when -pack'ing a module that includes a module of the same name
|
|
(Alain Frisch)
|
|
* PR#4231, PR#5461: warning 31 is now fatal by default
|
|
(Warning 31: A module is linked twice in the same executable.)
|
|
This is an interim solution; double-linking of modules has dangerous semantics,
|
|
eg. exception constructors end up with two distinct declarations.
|
|
(Alain Frisch)

- PR#4800: better compilation of tuple assignment

(Jérémie Dimino, Alain Frisch)
|
|
* PR#6438, PR#7059, GPR#315: Pattern guard disables exhaustiveness check
|
|
(function Some x when x = 0 -> ()) will now raise warning 8 (non-exhaustive)
|
|
instead of warning 25 (all clauses are guarded). 25 isn't raised anymore.
|
|
Projects that set warning 8 as an error may fail to compile (presumably
|

this is the semantics they wanted).

|
|
---------------------------
|
|
|
|
(Changes that can break existing programs are marked with a "*")
|
|
|
|
Language features:
|
|
- Attributes and extension nodes
|
|
(Alain Frisch)
|
|
- Generative functors (PR#5905)
|
|
(Jacques Garrigue)
|
|
* Module aliases
|
|
(Jacques Garrigue)
|
|
* Alternative syntax for string literals {id|...|id} (can break comments)
|
|
(Alain Frisch)
|
|
- Separation between read-only strings (type string) and read-write byte
|
|
sequences (type bytes). Activated by command-line option -safe-string.
|
|
(Damien Doligez)
|
|
- PR#6318: Exception cases in pattern matching
|
|
(Jeremy Yallop, backend by Alain Frisch)
|
|
- PR#5584: Extensible open datatypes
|
|
(Leo White)
|
|
|
|
Build system for the OCaml distribution:
|
|
- Use -bin-annot when building.
|
|
- Use GNU make instead of portable makefiles.
|
|
- Updated build instructions for 32-bit Mac OS X on Intel hardware.
|
|
|
|
Shedding weight:
|
|
* Removed Camlp4 from the distribution, now available as third-party software.
|
|
* Removed Labltk from the distribution, now available as a third-party library.
|
|
|
|
Type system:
|
|
* PR#6235: Keep typing of pattern cases independent in principal mode
|
|
(i.e. information from previous cases is no longer used when typing
|
|
patterns; cf. 'PR#6235' in testsuite/test/typing-warnings/records.ml)
|
|
(Jacques Garrigue)
|
|
- Allow opening a first-class module or applying a generative functor
|
|
in the body of a generative functor. Allow it also in the body of
|
|
an applicative functor if no types are created
|
|
(Jacques Garrigue, suggestion by Leo White)
|
|
* Module aliases are now typed in a specific way, which remembers their
|
|
identity. Compiled interfaces become smaller, but may depend on the
|
|
original modules. This also changes the signature inferred by
|
|
"module type of".
|
|
(Jacques Garrigue, feedback from Leo White, Mark Shinwell and Nick Chapman)
|
|
- PR#6331: Slight change in the criterion to distinguish private
|
|
abbreviations and private row types: create a private abbreviation for
|
|
closed objects and fixed polymorphic variants.
|
|
(Jacques Garrigue)
|
|
* PR#6333: Compare first class module types structurally rather than
|
|
nominally. Value subtyping allows module subtyping as long as the internal
|
|
representation is unchanged.
|
|
(Jacques Garrigue)
|
|
|
|
Compilers:
|
|
- More aggressive constant propagation, including float and
|
|
int32/int64/nativeint arithmetic. Constant propagation for floats
|
|
can be turned off with option -no-float-const-prop, for codes that
|
|
change FP rounding modes at run-time.
|
|
(Xavier Leroy)
|
|
- New back-end optimization pass: common subexpression elimination (CSE).
|
|
(Reuses results of previous computations instead of recomputing them.)
|
|
(Xavier Leroy)
|
|
- New back-end optimization pass: dead code elimination.

|
|
(Leo White, Mark Shinwell and Nick Chapman)
|
|
* "-o" now sets module name to the output file name up to the first "."
|
|
(it also applies when "-o" is not given, i.e. the module name is then
|
|
the input file name up to the first ".")

- PR#5377: New "#show_*" directives
|
|
(ygrek, Jacques Garrigue and Alain Frisch)
|
|
|
|
Runtime system:
|
|
- New configure option "-no-naked-pointers" to improve performance by
|
|
avoiding page table tests during block darkening and the marking phase
|
|
of the major GC. In this mode, all out-of-heap pointers must point at
|
|
things that look like OCaml values: in particular they must have a valid
|
|
header. The colour of said headers should be black.
|
|
(Mark Shinwell, reviews by Damien Doligez and Xavier Leroy)
|
|
- Fixed bug in native code version of [caml_raise_with_string] that could
|
|
potentially lead to heap corruption.
|
|
(Mark Shinwell)
|
|
* Blocks initialized by [CAMLlocal*] and [caml_alloc] are now filled with
|
|
[Val_unit] rather than zero.
|
|
(Mark Shinwell)
|
|
- Fixed a major performance problem on large heaps (~1GB) by making heap

(Plus special exceptions for MSVC.) In particular, emulation code for
|

64-bit integer arithmetic was removed, the C compiler must support a
|

Type system:

|
- PR#5759: use well-disciplined type information propagation to
|
|
disambiguate label and constructor names
|
|
(Jacques Garrigue, Alain Frisch and Leo White)
|
|
* Propagate type information towards pattern-matching, even in the presence of
|
|
polymorphic variants (discarding only information about possibly-present
|
|
constructors). As a result, matching against absent constructors is no longer
|
|
allowed for exact and fixed polymorphic variant types.
|

* PR#6035: Reject multiple declarations of the same method or instance variable

|
|
(Alain Frisch, Hongbo Zhang)

|

|
|
(Hongbo Zhang)
|
|
- ocamlopt now uses clang as assembler on OS X if available, which enables
|
|
CFI support for OS X.
|
|
(Benedikt Meurer)
|
|
- Added a new -short-paths option, which attempts to use the shortest
|
|
representation for type constructors inside types, taking open modules
|
|
into account. This can make types much more readable if your code
|
|
uses lots of functors.
|
|
(Jacques Garrigue)
|
|
- PR#5986: added flag -compat-32 to ocamlc, ensuring that the generated
|

bytecode executable can be loaded on 32-bit hosts.

|

|
- PR#5980: warning on open statements which shadow an existing
|
|
identifier (if it is actually used in the scope of the open); new
|
|
open! syntax to silence it locally
|
|
(Alain Frisch, thanks to a report of Daniel Bünzli)
|
|
* warning 3 is extended to warn about other deprecated features:

|
|
|
|
Runtime system:
|
|
* PR#6019: more efficient implementation of caml_modify() and caml_initialize().
|
|
The new implementations are less lenient than the old ones: now,
|
|
the destination pointer of caml_modify() must point within the minor or
|
|
major heaps, and the destination pointer of caml_initialize() must
|
|
point within the major heap.
|
|
(Xavier Leroy, from an experiment by Brian Nigito, with feedback

from Yaron Minsky and Gerd Stolpmann)

OCaml 4.00.0 (26 Jul 2012):
|
|
---------------------------
|
|
|
|
(Changes that can break existing programs are marked with a "*")
|
|
|
|
- The official name of the language is now OCaml.
|
|
|
|
Language features:
|
|
- Added Generalized Algebraic 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.
|
|
- Generation of CFI information, and filename/line number debugging (with -g)
|
|
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#5645: ocamldoc doesn't handle module/type substitution in signatures
|
|
- 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 OCAMLRUNPARAM
|
|
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 (changes the generated sequences)
|
|
- Format strings for formatted input/output revised to correct PR#5380
|
|
. Consistently treat %@ as a plain @ character
|
|
. Consistently treat %% as a plain % character
|
|
- Scanf: width and precision for floating point numbers are now handled
|
|
- 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.

|
- Added new operation 'compare_ext' to custom blocks, called when
|
|
comparing a custom block value with an unboxed integer.

Objective Caml 3.12.0 (2 Aug 2010):
|
|
-----------------------------------
|
|
|
|
(Changes that can break existing programs are marked with a "*" )
|
|
|
|
Language features:
|
|
- Shorthand notation for records: in expressions and patterns,
|
|
{ lbl } stands for { lbl = lbl } and { M.lbl } for { M.lbl = lbl }
|
|
- Record patterns of the form { lbl = pat; _ } to mark that not all
|
|
labels are listed, purposefully. (See new warning below.)
|
|
- Explicit naming of a generic type; in an expression
|
|
"fun ... (type t) ... -> e", the type t is considered abstract in its
|
|
scope (the arguments that follow it and the body of the function),
|
|
and then replaced by a fresh type variable. In particular, the type
|
|
t can be used in contexts where a type variable is not allowed
|
|
(e.g. for defining an exception in a local module).
|
|
- Explicit polymorphic types and polymorphic recursion. In let
|
|
definitions, one can write an explicit polymorphic type just
|
|
immediately the function name; the polymorphism will be enforced,
|
|
and recursive calls may use the polymorphism.
|
|
The syntax is the same as for polymorphic methods:
|
|
"let [rec] <ident> : 'a1 ... 'an. <typexp> = ..."
|
|
- First-class packages modules.
|
|
New kind of type expression, for packaged modules: (module PT).
|
|
New kind of expression, to pack a module as a first-class value:
|
|
(module MODEXPR : PT).
|
|
New kind of module expression, to unpack a first-class value as a module:
|
|
(val EXPR : PT).
|
|
PT is a package type of the form "S" or
|
|
"S with type t1 = ... and ... and type tn = ..." (S refers to a module type).
|
|
- Local opening of modules in a subexpression.
|
|
Syntax: "let open M in e", or "M.(e)"
|
|
- In class definitions, method and instance variable override can now
|
|
be made explicit, by writing "method!", "val!" or "inherit!" in place of
|
|
"method", "val" and "inherit". It is an error to override an
|
|
undefined member (or to use overriding inheritance when nothing get
|
|
overridden). Additionally, these constructs disactivate respectively
|
|
warnings 7 (method override, code 'M') and 13 (instance variable
|
|
override, code 'V'). Note that, by default, warning 7 is inactive
|
|
and warning 13 is active.
|
|
- "Destructive" substitution in signatures.
|
|
By writing "<signature> with type t := <typeconstr>" and
|
|
"<signature> with module M := <module-path>" one replaces "t" and "M"
|
|
inside the signature, removing their respective fields. Among other
|
|
uses, this allows to merge two signatures containing identically
|
|
named fields.
|
|
* While fixing PR#4824, also corrected a gaping hole in the type checker,
|
|
which allowed instantiating separately object parameters and instance
|
|
variables in an interface. This hole was here since the beginning of
|
|
ocaml, and as a result many programs using object inheritance in a non
|
|
trivial way will need to be corrected. You can look at lablgtk2 for an
|
|
example.
|
|
|
|
Compilers and toplevel:
|
|
- Warnings are now numbered and can be switched on and off individually.
|
|
The old system with letters referring to sets of warnings is still
|
|
supported.
|
|
- New warnings:
|
|
+ 9 (code 'R') to signal record patterns without "; _" where
|
|
some labels of the record type are not listed in the pattern.
|
|
+ 28 when giving a wildcard argument to a constant constructor in
|
|
a pattern-matching.
|
|
+ 29 when an end-of-line appears unescaped in a string constant.
|
|
+ 30 when the same constructor or record field is defined twice in
|
|
mutually-recursive type definitions.
|
|
* The semantics of warning 7 (code 'M', method override) have changed
|
|
(it now detects all overrides, not just repeated definitions inside
|
|
the same class body), and it is now inactive by default.
|
|
- Better error report in case of unbound qualified identifier: if the module
|
|
is unbound this error is reported in the first place.
|
|
- Added option '-strict-sequence' to force left hand part of sequence to have
|
|
type unit.
|
|
- Added option '-no-app-funct' to turn applicative functors off.
|
|
This option can help working around mysterious type incompatibilities
|
|
caused by the incomplete comparison of applicative paths F(X).t.
|
|
|
|
Native-code compiler:
|
|
- AMD64: shorter and slightly more efficient code generated for
|
|
float comparisons.
|
|
|
|
Standard library:
|
|
- Format: new function ikfprintf analoguous to ifprintf with a continuation
|
|
argument.
|
|
* PR#4210, #4245: stricter range checking in string->integer conversion
|
|
functions (int_of_string, Int32.of_string, Int64.of_string,
|
|
Nativeint.of_string). The decimal string corresponding to
|
|
max_int + 1 is no longer accepted.
|
|
- Scanf: to prevent confusion when mixing Scanf scanning functions and direct
|
|
low level input, value Scanf.stdin has been added.
|
|
* Random: changed the algorithm to produce better randomness. Now passes the
|
|
DieHard tests.
|
|
- Map: implement functions from Set that make sense for Map.
|
|
|
|
Other libraries:
|
|
* Str: letters that constitute a word now include digits 0-9 and
|
|
underscore _. This changes the interpretation of '\b' (word boundary)
|
|
in regexps, but is more consistent with other regexp libraries. (PR#4874).
|
|
|
|
Ocamlbuild:
|
|
- Add support for native dynlink.
|
|
|
|
New tool:
|
|
- ocamlobjinfo: displays various information, esp. dependencies, for
|
|
compiled OCaml files (.cmi, .cmo, .cma, .cmx, .cmxa, .cmxs, and bytecode
|
|
executables). Extends and makes more official the old objinfo tool
|
|
that was installed by some OCaml packages.
|
|
|
|
All tools:
|
|
- PR#4857: add a -vnum option to display the version number and nothing else
|
|
|

Objective Caml 3.11.0 (03 Dec 2008):
|
|
------------------------------------
|
|
|
|
(Changes that can break existing programs are marked with a "*" )
|
|
|
|
Language features:
|
|
- Addition of lazy patterns: "lazy <pat>" matches suspensions whose values,
|
|
after forcing, match the pattern <pat>.
|
|
- Introduction of private abbreviation types "type t = private <type-expr>",
|
|
for abstracting the actual manifest type in type abbreviations.
|
|
- Subtyping is now allowed between a private abbreviation and its definition,
|
|
and between a polymorphic method and its monomorphic instance.
|
|
|
|
Compilers:
|
|
- The file name for a compilation unit should correspond to a valid
|
|
identifier (Otherwise dynamic linking and other things can fail, and
|
|
a warning is emitted.)
|
|
* Revised -output-obj: the output name must now be provided; its
|
|
extension must be one of .o/.obj, .so/.dll, or .c for the
|
|
bytecode compiler. The compilers can now produce a shared library
|
|
(with all the needed -ccopts/-ccobjs options) directly.
|
|
- -dtypes renamed to -annot, records (in .annot files) which function calls
|
|
are tail calls.
|
|
- All compiler error messages now include a file name and location, for
|
|
better interaction with Emacs' compilation mode.
|
|
- Optimized compilation of "lazy e" when the argument "e" is
|
|
already evaluated.
|
|
- Optimized compilation of equality tests with a variant constant constructor.
|
|
- The -dllib options recorded in libraries are no longer ignored when
|
|
-use_runtime or -use_prims is used (unless -no_auto_link is
|
|
explicitly used).
|
|
- Check that at most one of -pack, -a, -shared, -c, -output-obj is
|
|
given on the command line.
|
|
- Optimized compilation of private types as regular manifest types
|
|
(e.g. abbreviation to float, float array or record types with only
|
|
float fields).
|
|
|
|
Native-code compiler:
|
|
- New port: Mac OS X / Intel in 64-bit mode (configure with -cc "gcc -m64").
|
|
- A new option "-shared" to produce a plugin that can be dynamically
|
|
loaded with the native version of Dynlink.
|
|
- A new option "-nodynlink" to enable optimizations valid only for code
|
|
that is never dynlinked (no-op except for AMD64).
|
|
- More aggressive unboxing of floats and boxed integers.
|
|
- Can select which assembler and asm options to use at configuration time.
|
|
|
|
Run-time system:
|
|
- New implementation of the page table describing the heap (two-level
|
|
array in 32 bits, sparse hashtable in 64 bits), fixes issues with address
|
|
space randomization on 64-bit OS (PR#4448).
|
|
- New "generational" API for registering global memory roots with the GC,
|
|
enables faster scanning of global roots.
|
|
(The functions are caml_*_generational_global_root in <caml/memory.h>.)
|
|
- New function "caml_raise_with_args" to raise an exception with several
|
|
arguments from C.
|
|
- Changes in implementation of dynamic linking of C code:
|
|
under Win32, use Alain Frisch's flexdll implementation of the dlopen
|
|
API; under MacOSX, use dlopen API instead of MacOSX bundle API.
|
|
- Programs may now choose a first-fit allocation policy instead of
|
|
the default next-fit. First-fit reduces fragmentation but is
|
|
slightly slower in some cases.
|
|
|
|
Standard library:
|
|
- Parsing library: new function "set_trace" to programmatically turn
|
|
on or off the printing of a trace during parsing.
|
|
- Printexc library: new functions "print_backtrace" and "get_backtrace"
|
|
to obtain a stack backtrace of the most recently raised exception.
|
|
New function "record_backtrace" to turn the exception backtrace mechanism
|
|
on or off from within a program.
|
|
- Scanf library: fine-tuning of meta format implementation;
|
|
fscanf behaviour revisited: only one input buffer is allocated for any
|
|
given input channel;
|
|
the %n conversion does not count a lookahead character as read.
|
|
|
|
Other libraries:
|
|
- Dynlink: on some platforms, the Dynlink library is now available in
|
|
native code. The boolean Dynlink.is_native allows the program to
|
|
know whether it has been compiled in bytecode or in native code.
|
|
- Bigarrays: added "unsafe_get" and "unsafe_set"
|
|
(non-bound-checking versions of "get" and "set").
|
|
- Bigarrays: removed limitation "array dimension < 2^31".
|
|
- Labltk: added support for TK 8.5.
|
|
- Num: added conversions between big_int and int32, nativeint, int64.
|
|
More efficient implementation of Num.quo_num and Num.mod_num.
|
|
- Threads: improved efficiency of mutex and condition variable operations;
|
|
improved interaction with Unix.fork (PR#4577).
|
|
- Unix: added getsockopt_error returning type Unix.error.
|
|
Added support for TCP_NODELAY and IPV6_ONLY socket options.
|
|
- Win32 Unix: "select" now supports all kinds of file descriptors.
|
|
Improved emulation of "lockf" (PR#4609).
|
|
|
|
Tools:
|
|
- ocamldebug now supported under Windows (MSVC and Mingw ports),
|
|
but without the replay feature. (Contributed by Dmitry Bely
|
|
and Sylvain Le Gall at OCamlCore with support from Lexifi.)
|
|
- ocamldoc: new option -no-module-constraint-filter to include functions
|
|
hidden by signature constraint in documentation.
|
|
- ocamlmklib and ocamldep.opt now available under Windows ports.
|
|
- ocamlmklib no longer supports the -implib option.
|
|
- ocamlnat: an experimental native toplevel (not built by default).
|
|
|
|
Camlp4:
|
|
* programs linked with camlp4lib.cma now also need dynlink.cma.
|
|
|
|

|
Objective Caml 3.10.0 (18 May 2007):
|
|
------------------------------------
|
|
|
|
(Changes that can break existing programs are marked with a "*" )
|
|
|
|
Language features:
|
|
- Added virtual instance variables in classes "val virtual v : t"
|
|
* Changed the behaviour of instance variable overriding; the new
|
|
definition replaces the old one, rather than creating a new
|
|
variable.
|
|
|
|
New tools:
|
|
- ocamlbuild: compilation manager for OCaml applications and libraries.
|
|
See draft documentation at http://gallium.inria.fr/~pouillar/
|
|
* Camlp4: heavily revised implementation, new API.
|
|
|
|
New ports:
|
|
- MacOS X PowerPC 64 bits.
|
|
- MS Windows 64 bits (x64) using the Microsoft PSDK toolchain.
|
|
- MS Windows 32 bits using the Visual Studio 2005 toolchain.
|
|
|
|
Compilers:
|
|
- Faster type-checking of functor applications.
|
|
- Referencing an interface compiled with -rectypes from a module
|
|
not compiled with -rectypes is now an error.
|
|
- Revised the "fragile matching" warning.
|
|
|
|
Native-code compiler:
|
|
- Print a stack backtrace on an uncaught exception.
|
|
(Compile and link with ocamlopt -g; execute with OCAMLRUNPARAM=b.)
|
|
Supported on Intel/AMD in 32 and 64 bits, PPC in 32 and 64 bits.
|
|
- Stack overflow detection on MS Windows 32 bits (courtesy O. Andrieu).
|
|
- Stack overflow detection on MacOS X PPC and Intel.
|
|
- Intel/AMD 64 bits: generate position-independent code by default.
|
|
- Fixed bug involving -for-pack and missing .cmx files (PR#4124).
|
|
- Fixed bug causing duplication of literals (PR#4152).
|
|
|
|
Run-time system:
|
|
- C/Caml interface functions take "char const *" arguments
|
|
instead of "char *" when appropriate.
|
|
- Faster string comparisons (fast case if strings are ==).
|
|
|
|
Standard library:
|
|
- Refined typing of format strings (type format6).
|
|
- Printf, Format: new function ifprintf that consumes its arguments
|
|
and prints nothing (useful to print conditionally).
|
|
- Scanf:
|
|
new function format_from_string to convert a string to a format string;
|
|
new %r conversion to accomodate user defined scanners.
|
|
- Filename: improved Win32 implementation of Filename.quote.
|
|
- List: List.nth now tail-recursive.
|
|
- Sys: added Sys.is_directory. Some functions (e.g. Sys.command) that
|
|
could incorrectly raise Sys_io_blocked now raise Sys_error as intended.
|
|
- String and Char: the function ``escaped'' now escapes all the characters
|
|
especially handled by the compiler's lexer (PR#4220).
|
|
|
|
Other libraries:
|
|
- Bigarray: mmap_file takes an optional argument specifying
|
|
the start position of the data in the mapped file.
|
|
- Dynlink: now defines only two modules, Dynlink and Dynlinkaux (internal),
|
|
reducing risks of name conflicts with user modules.
|
|
- Labltk under Win32: now uses Tcl/Tk 8.4 instead of 8.3 by default.
|
|
- VM threads: improved performance of I/O operations (less polling).
|
|
- Unix: new function Unix.isatty.
|
|
- Unix emulation under Win32:
|
|
fixed incorrect error reporting in several functions (PR#4097);
|
|
better handling of channels opened on sockets (PR#4098);
|
|
fixed GC bug in Unix.system (PR#4112).
|
|
|
|
Documentation generator (OCamldoc):
|
|
- correctly handle '?' in value names (PR#4215)
|
|
- new option -hide-warnings not to print ocamldoc warnings
|
|
|
|
Lexer generator (ocamllex): improved error reporting.
|
|
|
|
License: fixed a typo in the "special exception" to the LGPL.
|
|
|
|
|

Objective Caml 3.09.0 (27 Oct 2006):
|
|
------------------------------------
|
|
|
|
(Changes that can break existing programs are marked with a "*" )
|
|
|
|
Language features:
|
|
- Introduction of private row types, for abstracting the row in object
|
|
and variant types.
|
|
|
|
Type checking:
|
|
- Polymorphic variants with at most one constructor [< `A of t] are no
|
|
longer systematically promoted to the exact type [`A of t]. This was
|
|
more confusing than useful, and created problems with private row
|
|
types.
|
|
|
|
Both compilers:
|
|
- Added warnings 'Y' and 'Z' for local variables that are bound but
|
|
never used.
|
|
- Added warning for some uses non-returning functions (e.g. raise), when they
|
|
are passed extra arguments, or followed by extra statements.
|
|
- Pattern matching: more prudent compilation in case of guards; fixed PR#3780.
|
|
- Compilation of classes: reduction in size of generated code.
|
|
- Compilation of "module rec" definitions: fixed a bad interaction with
|
|
structure coercion (to a more restrictive signature).
|
|
|
|
Native-code compiler (ocamlopt):
|
|
* Revised implementation of the -pack option (packing of several compilation
|
|
units into one). The .cmx files that are to be packed with
|
|
"ocamlopt -pack -o P.cmx" must be compiled with "ocamlopt -for-pack P".
|
|
In exchange for this additional constraint, ocamlopt -pack is now
|
|
available on all platforms (no need for binutils).
|
|
* Fixed wrong evaluation order for arguments to certain inlined functions.
|
|
- Modified code generation for "let rec ... and ..." to reduce compilation
|
|
time (which was quadratic in the number of mutually-recursive functions).
|
|
- x86 port: support tail-calls for functions with up to 21 arguments.
|
|
- AMD64 port, Linux: recover from system stack overflow.
|
|
- Sparc port: more portable handling of out-of-bound conditions
|
|
on systems other than Solaris.
|
|
|
|
Standard library:
|
|
- Pervasives: faster implementation of close_in, close_out.
|
|
set_binary_mode_{out,in} now working correctly under Cygwin.
|
|
- Printf: better handling of partial applications of the printf functions.
|
|
- Scanf: new function sscanf_format to read a format from a
|
|
string. The type of the resulting format is dynamically checked and
|
|
should be the type of the template format which is the second argument.
|
|
- Scanf: no more spurious lookahead attempt when the end of file condition
|
|
is set and a correct token has already been read and could be returned.
|
|
|
|
Other libraries:
|
|
- System threads library: added Thread.sigmask; fixed race condition
|
|
in signal handling.
|
|
- Bigarray library: fixed bug in Array3.of_array.
|
|
- Unix library: use canonical signal numbers in results of Unix.wait*;
|
|
hardened Unix.establish_server against EINTR errors.
|
|
|
|
Run-time system:
|
|
- Support platforms where sizeof(void *) = 8 and sizeof(long) = 4.
|
|
- Improved and cleaned up implementation of signal handling.
|
|
|
|
Replay debugger:
|
|
- Improved handling of locations in source code.
|
|
|
|
OCamldoc:
|
|
- extensible {foo } syntax
|
|
- user can give .txt files on the command line, containing ocamldoc formatted
|
|
text, to be able to include bigger texts out of source files
|
|
- -o option is now used by the html generator to indicate the prefix
|
|
of generated index files (to avoid conflict when a Index module exists
|
|
on case-insensitive file systems).
|
|
|
|
Miscellaneous:
|
|
- Configuration information is installed in `ocamlc -where`/Makefile.config
|
|
and can be used by client Makefiles or shell scripts.
|
|

- typing: fix unsoundness in type declaration variance inference.
|
|
Type parameters which are constrained must now have an explicit variant
|
|
annotation, otherwise they are invariant. This is not backward
|
|
compatible, so this might break code which either uses subtyping or
|
|
uses the relaxed value restriction (i.e. was not typable before 3.07)

|
|
|
|
Licence:
|
|
- The emacs files are now under GPL
|

|
Objective Caml 3.08.0 (13 Jul 2004):
|
|
------------------------------------
|
|
|
|
(Changes that can break existing programs are marked with a "*" )
|
|
|
|
Language features:
|
|
- Support for immediate objects, i.e. objects defined without going
|
|
through a class. (Syntax is "object <fields and methods> end".)
|
|
|
|
Type-checking:
|
|
- When typing record construction and record patterns, can omit
|
|
the module qualification on all labels except one. I.e.
|
|
{ M.l1 = ...; l2 = ... } is interpreted as { M.l1 = ...; M.l2 = ... }
|
|
|
|
Both compilers:
|
|
- More compact compilation of classes.
|
|
- Much more efficient handling of class definitions inside functors
|
|
or local modules.
|
|
- Simpler representation for method tables. Objects can now be marshaled
|
|
between identical programs with the flag Marshal.Closures.
|
|
- Improved error messages for objects and variants.
|
|
- Improved printing of inferred module signatures (toplevel and ocamlc -i).
|
|
Recursion between type, class, class type and module definitions is now
|
|
correctly printed.
|
|
- The -pack option now accepts compiled interfaces (.cmi files) in addition
|
|
to compiled implementations (.cmo or .cmx).
|
|
* A compile-time error is signaled if an integer literal exceeds the
|
|
range of representable integers.
|
|
- Fixed code generation error for "module rec" definitions.
|
|
- The combination of options -c -o sets the name of the generated
|
|
.cmi / .cmo / .cmx files.
|
|
|
|
Bytecode compiler:
|
|
- Option -output-obj is now compatible with Dynlink and
|
|
with embedded toplevels.
|
|
|
|
Native-code compiler:
|
|
- Division and modulus by zero correctly raise exception Division_by_zero
|
|
(instead of causing a hardware trap).
|
|
- Improved compilation time for the register allocation phase.
|
|
- The float constant -0.0 was incorrectly treated as +0.0 on some processors.
|
|
- AMD64: fixed bugs in asm glue code for GC invocation and exception raising
|
|
from C.
|
|
- IA64: fixed incorrect code generated for "expr mod 1".
|
|
- PowerPC: minor performance tweaks for the G4 and G5 processors.
|
|
|
|
Standard library:
|
|
* Revised handling of NaN floats in polymorphic comparisons.
|
|
The polymorphic boolean-valued comparisons (=, <, >, etc) now treat
|
|
NaN as uncomparable, as specified by the IEEE standard.
|
|
The 3-valued comparison (compare) treats NaN as equal to itself
|
|
and smaller than all other floats. As a consequence, x == y
|
|
no longer implies x = y but still implies compare x y = 0.
|
|
* String-to-integer conversions now fail if the result overflows
|
|
the range of integers representable in the result type.
|
|
* All array and string access functions now raise
|
|
Invalid_argument("index out of bounds") when a bounds check fails.
|
|
In earlier releases, different exceptions were raised
|
|
in bytecode and native-code.
|
|
- Module Buffer: new functions Buffer.sub, Buffer.nth
|
|
- Module Int32: new functions Int32.bits_of_float, Int32.float_of_bits.
|
|
- Module Map: new functions is_empty, compare, equal.
|
|
- Module Set: new function split.
|
|
* Module Gc: in-order finalisation, new function finalise_release.
|
|
|
|
Other libraries:
|
|
- The Num library: complete reimplementation of the C/asm lowest
|
|
layer to work around potential licensing problems.
|
|
Improved speed on the PowerPC and AMD64 architectures.
|
|
- The Graphics library: improved event handling under MS Windows.
|
|
- The Str library: fixed bug in "split" functions with nullable regexps.
|
|
- The Unix library:
|
|
. Added Unix.single_write.
|
|
. Added support for IPv6.
|
|
. Bug fixes in Unix.closedir.
|
|
. Allow thread switching on Unix.lockf.
|
|
|
|
Runtime System:
|
|
* Name space depollution: all global C identifiers are now prefixed
|
|
with "caml" to avoid name clashes with other libraries. This
|
|
includes the "external" primitives of the standard runtime.
|
|
|
|
Ports:
|
|
- Windows ports: many improvements in the OCamlWin toplevel application
|
|
(history, save inputs to file, etc). Contributed by Christopher A. Watford.
|
|
- Native-code compilation supported for HPPA/Linux. Contributed by Guy Martin.
|
|
- Removed support for MacOS9. Mac OS 9 is obsolete and the port was not
|
|
updated since 3.05.
|
|
- Removed ocamlopt support for HPPA/Nextstep and Power/AIX.
|
|
|
|
Ocamllex:
|
|
- #line directives in the input file are now accepted.
|
|
- Added character set concatenation operator "cset1 # cset2".
|
|
|
|
Ocamlyacc:
|
|
- #line directives in the input file are now accepted.
|
|
|
|
Camlp4:
|
|
* Support for new-style locations (line numbers, not just character numbers).
|
|
- See camlp4/CHANGES and camlp4/ICHANGES for more info.
|
|
|
|
|
|
Objective Caml 3.07 (29 Sep 2003):
|
|
----------------------------------
|
|
|
|
Language features:
|
|
- Experimental support for recursive module definitions
|
|
module rec A : SIGA = StructA and B : SIGB = StructB and ...
|
|
- Support for "private types", or more exactly concrete data types
|
|
with private constructors or labels. These data types can be
|
|
de-structured normally in pattern matchings, but values of these
|
|
types cannot be constructed directly outside of their defining module.
|
|
- Added integer literals of types int32, nativeint, int64
|
|
(written with an 'l', 'n' or 'L' suffix respectively).
|
|
|
|
Type-checking:
|
|
- Allow polymorphic generalization of covariant parts of expansive
|
|
expressions. For instance, if f: unit -> 'a list, "let x = f ()"
|
|
gives "x" the generalized type forall 'a. 'a list, instead of '_a list
|
|
as before.
|
|
- The typing of polymorphic variants in pattern matching has changed.
|
|
It is intended to be more regular, sticking to the principle of "closing
|
|
only the variants which would be otherwise incomplete". Two potential
|
|
consequences: (1) some types may be left open which were closed before,
|
|
and the resulting type might not match the interface anymore (expected to
|
|
be rare); (2) in some cases an incomplete match may be generated.
|
|
- Lots of bug fixes in the handling of polymorphism and recursion inside
|
|
types.
|
|
- Added a new "-dtypes" option to ocamlc/ocamlopt, and an emacs extension
|
|
"emacs/caml-types.el". The compiler option saves inferred type information
|
|
to file *.annot, and the emacs extension allows the user to look at the
|
|
type of any subexpression in the source file. Works even in the case
|
|
of a type error (all the types computed up to the error are available).
|
|
This new feature is also supported by ocamlbrowser.
|
|
- Disable "method is overridden" warning when the method was explicitly
|
|
redefined as virtual beforehand (i.e. not through inheritance). Typing
|
|
and semantics are unchanged.
|
|
|
|
Both compilers:
|
|
- Added option "-dtypes" to dump detailed type information to a file.
|
|
- The "-i" option no longer generates compiled files, it only prints
|
|
the inferred types.
|
|
- The sources for the module named "Mod" can be placed either in Mod.ml or
|
|
in mod.ml.
|
|
- Compilation of "let rec" on non-functional values: tightened some checks,
|
|
relaxed some other checks.
|
|
- Fixed wrong code that was generated for "for i = a to max_int"
|
|
or "for i = a downto min_int".
|
|
- An explicit interface Mod.mli can now be provided for the module obtained
|
|
by ocamlc -pack -o Mod.cmo ... or ocamlopt -pack -o Mod.cmx ...
|
|
- Revised internal handling of source code locations, now handles
|
|
preprocessed code better.
|
|
- Pattern-matching bug on float literals fixed.
|
|
- Minor improvements on pattern-matching over variants.
|
|
- More efficient compilation of string comparisons and the "compare" function.
|
|
- More compact code generated for arrays of constants.
|
|
- Fixed GC bug with mutable record fields of type "exn".
|
|
- Added warning "E" for "fragile patterns": pattern matchings that would
|
|
not be flagged as partial if new constructors were added to the data type.
|
|
|
|
Bytecode compiler:
|
|
- Added option -vmthread to select the threads library with VM-level
|
|
scheduling. The -thread option now selects the system threads library.
|
|
|
|
Native-code compiler:
|
|
- New port: AMD64 (Opteron).
|
|
- Fixed instruction selection bug on expressions of the kind (raise Exn)(arg).
|
|
- Several bug fixes in ocamlopt -pack (tracking of imported modules,
|
|
command line too long).
|
|
- Signal handling bug fixed.
|
|
- x86 port:
|
|
Added -ffast-math option to use inline trigo and log functions.
|
|
Small performance tweaks for the Pentium 4.
|
|
Fixed illegal "imul" instruction generated by reloading phase.
|
|
- Sparc port:
|
|
Enhanced code generation for Sparc V8 (option -march=v8) and
|
|
Sparc V9 (option -march=v9).
|
|
Profiling support added for Solaris.
|
|
- PowerPC port:
|
|
Keep stack 16-aligned for compatibility with C calling conventions.
|
|
|
|
Toplevel interactive system:
|
|
- Tightened interface consistency checks between .cmi files, .cm[oa] files
|
|
loaded by #load, and the running toplevel.
|
|
- #trace on mutually-recursive functions was broken, works again.
|
|
- Look for .ocamlinit file in home directory in addition to the current dir.
|
|
|
|
Standard library:
|
|
- Match_failure and Assert_failure exceptions now report
|
|
(file, line, column), instead of (file, starting char, ending char).
|
|
- float_of_string, int_of_string: some ill-formed input strings were not
|
|
rejected.
|
|
- Added format concatenation, string_of_format, format_of_string.
|
|
- Module Arg: added new option handlers Set_string, Set_int, Set_float,
|
|
Symbol, Tuple.
|
|
- Module Format: tag handling is now turned off by default,
|
|
use [Format.set_tags true] to activate.
|
|
- Modules Lexing and Parsing: added better handling of positions
|
|
in source file. Added function Lexing.flush_input.
|
|
- Module Scanf: %n and %N formats to count characters / items read so far;
|
|
assorted bug fixes, %! to match end of input. New ``_'' special
|
|
flag to skip reresulting value.
|
|
- Module Format: tags are not activated by default.
|
|
- Modules Set and Map: fixed bugs causing trees to become unbalanced.
|
|
- Module Printf: less restrictive typing of kprintf.
|
|
- Module Random: better seeding; functions to generate random int32, int64,
|
|
nativeint; added support for explicit state management.
|
|
- Module Sys: added Sys.readdir for reading the contents of a directory.
|
|
|
|
Runtime system:
|
|
- output_value/input_value: fixed bug with large blocks (>= 4 Mwords)
|
|
produced on a 64-bit platform and incorrectly read back on a 32-bit
|
|
platform.
|
|
- Fixed memory compaction bug involving input_value.
|
|
- Added MacOS X support for dynamic linking of C libraries.
|
|
- Improved stack backtraces on uncaught exceptions.
|
|
- Fixed float alignment problem on Sparc V9 with gcc 3.2.
|
|
|
|
Other libraries:
|
|
- Dynlink:
|
|
By default, dynamically-loaded code now has access to all
|
|
modules defined by the program; new functions Dynlink.allow_only
|
|
and Dynlink.prohibit implement access control.
|
|
Fixed Dynlink problem with files generated with ocamlc -pack.
|
|
Protect against references to modules not yet fully initialized.
|

|
|
and LGPL instead of GPL.

- Graphics: fixed draw_rect and fill_rect bug under X11.
|
|
- System threads and bytecode threads libraries can be both installed.
|
|
- System threads: better implementation of Thread.exit.
|
|
- Bytecode threads: fixed two library initialization bugs.
|
|
- Unix: make Unix.openfile blocking to account for named pipes;
|
|
GC bug in Unix.*stat fixed; fixed problem with Unix.dup2 on Windows.
|
|
|
|
Ocamllex:
|
|
- Can name parts of the matched input text, e.g.
|
|
"0" (['0'-'7']+ as s) { ... s ... }
|
|
|
|
Ocamldebug:
|
|
- Handle programs that run for more than 2^30 steps.
|
|
|
|
Emacs mode:
|
|
- Added file caml-types.el to interactively display the type information
|
|
saved by option -dtypes.
|

|
|
|
|
Language features:
|
|
- Support for polymorphic methods and record fields.
|
|
- Allows _ separators in integer and float literals, e.g. 1_000_000.
|

thus removing assembler failures on large functions.
|
|
- IA64 port: fixed code generation bug for 3-way constructor matching.
|
|
|
|
Toplevel interactive system:

|
|
added Digest.to_hex.
|
|

|
|
- Module Stack: added Stack.is_empty.
|
|
- Module Pervasives:

opening in "append" mode automatically sets "write" mode;
|
|
files are now opened in close-on-exec mode;
|
|
string_of_float distinguishes its output from a plain integer;

|
|
export the tcl interpreter as caml value, to avoid DLL dependencies.
|
|
- Unix:

|
- ocamldoc (the documentation generator) is now part of the distribution.
|
|
- Debugger: now supports the option -I +dir.
|
|
- ocamllex: supports the same identifiers as ocamlc; warns for

|
bad \ escapes in strings and characters.
|
|
- ocamlbrowser:
|
|
recenter the module boxes when showing a cross-reference;
|
|
include the current directory in the ocaml path.

|
|
Windows port:
|
|
- Can now compile with Mingw (the GNU compilers without the Cygwin
|
|
runtime library) in addition to MSVC.
|
|
- Toplevel GUI: wrong filenames were given to #use and #load commands;
|

|
|
|
|
|
|
Objective Caml 3.04 (13 Dec 2001):
|
|
----------------------------------
|
|
|
|
Type-checker:
|
|
- Allowed coercing self to the type of the current class, avoiding
|
|
an obscure error message about "Self type cannot be unified..."
|
|
|
|
Both compilers:
|
|
- Use OCAMLLIB environment variable to find standard library, falls
|
|
back on CAMLLIB if not defined.
|
|
- Report out-of-range ASCII escapes in character or string literals
|
|
such as "\256".
|
|
|
|
Byte-code compiler:
|
|
- The -use-runtime and -make-runtime flags are back by popular demand
|
|
(same behavior as in 3.02).
|
|
- Dynamic loading (of the C part of mixed Caml/C libraries): arrange that
|
|
linking in -custom mode uses the static libraries for the C parts,
|
|
not the shared libraries, for maximal robustness and compatibility with
|
|
3.02.
|
|
|
|
Native-code compiler:
|
|
- Fixed bug in link-time consistency checking.
|
|
|
|
Tools:
|
|
- ocamlyacc: added parser debugging support (set OCAMLRUNPARAM=p to get
|
|
a trace of the pushdown automaton actions).
|
|
- ocamlcp: was broken in 3.03 (Sys_error), fixed.
|
|
|
|
Run-time system:
|
|
- More work on dynamic loading of the C part of mixed Caml/C libraries.
|
|
- On uncaught exception, flush output channels before printing exception
|
|
message and backtrace.
|
|
- Corrected several errors in exception backtraces.
|
|
|
|
Standard library:
|
|
- Pervasives: integer division and modulus are now fully specified
|
|
on negative arguments (with round-towards-zero semantics).
|
|
- Pervasives.float_of_string: now raises Failure on ill-formed input.
|
|
- Pervasives: added useful float constants max_float, min_float, epsilon_float.
|
|
- printf functions in Printf and Format: added % formats for int32, nativeint,
|
|
int64; "*" in width and precision specifications now supported
|
|
(contributed by Thorsten Ohl).
|
|
- Added Hashtbl.copy, Stack.copy.
|
|
- Hashtbl: revised resizing strategy to avoid quadratic behavior
|
|
on Hashtbl.add.
|
|
- New module MoreLabels providing labelized versions of modules
|
|
Hashtbl, Map and Set.
|
|
- Pervasives.output_value and Marshal.to_* : improved hashing strategy
|
|
for internal data structures, avoid excessive slowness on
|
|
quasi-linearly-allocated inputs.
|
|
|
|
Other libraries:
|
|
- Num: fixed bug in big integer exponentiation (Big_int.power_*).
|
|
|
|
Windows port:
|
|
- New GUI for interactive toplevel (Jacob Navia).
|
|
- The Graphics library is now available for stand-alone executables
|
|
(Jacob Navia).
|
|
- Unix library: improved reporting of system error codes.
|
|
- Fixed error in "globbing" of * and ? patterns on command line.
|
|
|
|
Emacs mode: small fixes; special color highlighting for ocamldoc comments.
|
|
|
|
License: added special exception to the LGPL'ed code (libraries and
|
|
runtime system) allowing unrestricted linking, whether static or dynamic.
|
|
|
|
|
|
Objective Caml 3.03 ALPHA (12 Oct 2001):
|
|
----------------------------------------
|
|
|
|
Language:
|
|
- Removed built-in syntactic sugar for streams and stream patterns
|
|
[< ... >], now supported via CamlP4, which is now included in the
|
|
distribution.
|
|
- Switched the default behaviour to labels mode (labels are compulsory),
|
|
but allows omitting labels when a function application is complete.
|
|
-nolabels mode is available but deprecated for programming.
|
|
(See also scrapelabels and addlabels tools below.)
|
|
- Removed all labels in the standard libraries, except labltk.
|
|
Labelized versions are kept for ArrayLabels, ListLabels, StringLabels
|
|
and UnixLabels. "open StdLabels" gives access to the first three.
|
|
- Extended polymorphic variant type syntax, allowing union types and
|
|
row abbreviations for both sub- and super-types. #t deprecated in types.
|
|
- See the Upgrading file for how to adapt to all the changes above.
|
|
|
|
Type-checker:
|
|
- Fixed obscure bug in module typing causing the type-checker to loop
|
|
on signatures of the form
|
|
module type M
|
|
module A: sig module type T = sig module T: M end end
|
|
module B: A.T
|
|
- Improved efficiency of module type-checking via lazy computation of
|
|
certain signature summary information.
|
|
- An empty polymorphic variant type is now an error.
|
|
|
|
Both compilers:
|
|
- Fixed wrong code generated for "struct include M ... end" when M
|
|
contains one or several "external" declarations.
|
|
|
|
Byte-code compiler:
|
|
- Protect against VM stack overflow caused by module initialization code
|
|
with many local variables.
|
|
- Support for dynamic loading of the C part of mixed Caml/C libraries.
|
|
- Removed the -use-runtime and -make-runtime flags, obsoleted by dynamic
|
|
loading of C libraries.
|
|
|
|
Native-code compiler:
|
|
- Attempt to recover gracefully from system stack overflow. Currently
|
|
works on x86 under Linux and BSD.
|
|
- Alpha: work around "as" bug in Tru64 5.1.
|
|
|
|
Toplevel environment:
|
|
- Revised printing of inferred types and evaluation results
|
|
so that an external printer (e.g. Camlp4's) can be hooked in.
|
|
|
|
Tools:
|
|
- The CamlP4 pre-processor-pretty-printer is now included in the standard
|
|
distribution.
|
|
- New tool ocamlmklib to help build mixed Caml/C libraries.
|
|
- New tool scrapelabels and addlabels, to either remove (non-optional)
|
|
labels in interfaces, or automatically add them in the definitions.
|
|
They provide easy transition from classic mode ocaml 3.02 sources,
|
|
depending on whether you want to keep labels or not.
|
|
- ocamldep: added -pp option to handle preprocessed source files.
|
|
|
|
Run-time system:
|
|
- Support for dynamic loading of the C part of mixed Caml/C libraries.
|
|
Currently works under Linux, FreeBSD, Windows, Tru64, Solaris and Irix.
|
|
- Implemented registration of global C roots with a skip list,
|
|
runs much faster when there are many global C roots.
|
|
- Autoconfiguration script: fixed wrong detection of Mac OS X; problem
|
|
with the Sparc, gcc 3.0, and float alignment fixed.
|
|
|
|
Standard library:
|
|
- Added Pervasives.flush_all to flush all opened output channels.
|
|
|
|
Other libraries:
|
|
- All libraries revised to allow dynamic loading of the C part.
|
|
- Graphics under X Windows: revised event handling, should no longer lose
|
|
mouse events between two calls to wait_next_event(); wait_next_event()
|
|
now interruptible by signals.
|
|
- Bigarrays: fixed bug in marshaling of big arrays.
|
|
|
|
Windows port:
|
|
- Fixed broken Unix.{get,set}sockopt*
|
|
|
|
|
|
|
|
Objective Caml 3.02 (30 Jul 2001):
|
|
----------------------------------
|
|
|
|
Both compilers:
|
|
- Fixed embarrassing bug in pattern-matching compilation
|
|
(affected or-patterns containing variable bindings).
|
|
- More optimizations in pattern-matching compilation.
|
|
|
|
Byte-code compiler:
|
|
- Protect against VM stack overflow caused by functions with many local
|
|
variables.
|
|
|
|
Native-code compiler:
|
|
- Removed re-sharing of string literals, causes too many surprises with
|
|
in-place string modifications.
|
|
- Corrected wrong compilation of toplevel "include" statements.
|
|
- Fixed bug in runtime function "callbackN_exn".
|
|
- Signal handlers receive the conventional signal number as argument
|
|
instead of the system signal number (same behavior as with the
|
|
bytecode compiler).
|
|
- ARM port: fixed issue with immediate operand overflow in large functions.
|
|
|
|
Toplevel environment:
|
|
- User-definer printers (for #install_printer) now receive as first argument
|
|
the pretty-printer formatter where to print their second argument.
|
|
Old printers (with only one argument) still supported for backward
|
|
compatibility.
|
|
|
|
Standard library:
|
|
- Module Hashtbl: added Hashtbl.fold.
|
|
|
|
Other libraries:
|
|
- Dynlink: better error reporting in add_interfaces for missing .cmi files.
|
|
- Graphics: added more drawing functions (multiple points, polygons,
|
|
multiple lines, splines).
|
|
- Bytecode threads: the module Unix is now thread-safe, ThreadUnix is
|
|
deprecated. Unix.exec* now resets standard descriptors to blocking mode.
|
|
- Native threads: fixed a context-switch-during-GC problem causing
|
|
certain C runtime functions to fail, most notably input_value.
|
|
- Unix.inet_addr_of_string: call inet_aton() when available so as to
|
|
handle correctly the address 255.255.255.255.
|
|
- Unix: added more getsockopt and setsockopt functions to get/set
|
|
options that have values other than booleans.
|
|
- Num: added documentation for the Big_int module.
|
|
|
|
Tools:
|
|
- ocamldep: fixed wrong dependency issue with nested modules.
|
|
|
|
Run-time system:
|
|
- Removed floating-point error at start-up on some non-IEEE platforms
|
|
(e.g. FreeBSD prior to 4.0R).
|
|
- Stack backtrace mechanism now works for threads that terminate on
|
|
an uncaught exception.
|
|
|
|
Auto-configuration:
|
|
- Updated config.guess and config.sub scripts, should recognize a greater
|
|
number of recent platform.
|
|
|
|
Windows port:
|
|
- Fixed broken Unix.waitpid. Unix.file_descr can now be compared or hashed.
|
|
- Toplevel application: issue with spaces in name of stdlib directory fixed.
|
|
|
|
MacOS 9 port:
|
|
- Removed the last traces of support for 68k
|
|
|
|
|
|
Objective Caml 3.01 (09 Mar 2001):
|
|
----------------------------------
|
|
|
|
New language features:
|
|
- Variables are allowed in "or" patterns, e.g.
|
|
match l with [t] | [_;t] -> ... t ...
|
|
- "include <structure expression>" to re-export all components of a
|
|
structure inside another structure.
|
|
- Variance annotation on parameters of type declarations, e.g.
|
|
type (+'a,-'b,'c) t (covariant in 'a, contravariant in 'b, invariant in 'c)
|
|
|
|
New ports:
|
|
- Intel IA64/Itanium under Linux (including the native-code compiler).
|
|
- Cygwin under MS Windows. This port is an alternative to the earlier
|
|
Windows port of OCaml, which relied on MS compilers; the Cygwin
|
|
Windows port does not need MS Visual C++ nor MASM, runs faster
|
|
in bytecode, and has a better implementation of the Unix library,
|
|
but currently lacks threads and COM component support.
|
|
|
|
Type-checking:
|
|
- Relaxed "monomorphic restriction" on type constructors in a
|
|
mutually-recursive type definition, e.g. the following is again allowed
|
|
type u = C of int t | D of string t and 'a t = ...
|
|
- Fixed name-capture bug in "include SIG" and "SIG with ..." constructs.
|
|
- Improved implicit subtypes built by (... :> ty), closer to intuition.
|
|
- Several bug fixes in type-checking of variants.
|
|
- Typing of polymorphic variants is more restrictive:
|
|
do not allow conjunctive types inside the same pattern matching.
|
|
a type has either an upper bound, or all its tags are in the lower bound.
|
|
This may break some programs (this breaks lablgl-0.94).
|
|
|
|
Both compilers:
|
|
- Revised compilation of pattern matching.
|
|
- Option -I +<subdir> to search a subdirectory <subdir> of the standard
|
|
library directory (i.e. write "ocamlc -I +labltk" instead of
|
|
"ocamlc -I /usr/local/lib/ocaml/labltk").
|
|
- Option -warn-error to turn warnings into errors.
|
|
- Option -where to print the location of the standard library directory.
|
|
- Assertions are now type-checked even if the -noassert option is given,
|
|
thus -noassert can no longe change the types of modules.
|
|
|
|
Bytecode compiler and bytecode interpreter:
|
|
- Print stack backtrace when a program aborts due to an uncaught exception
|
|
(requires compilation with -g and running with ocamlrun -b or
|
|
OCAMLRUNPARAM="b=1").
|
|
|
|
Native-code compiler:
|
|
- Better unboxing optimizations on the int32, int64, and nativeint types.
|
|
- Tail recursion preserved for functions having more parameters than
|
|
available registers (but tail calls to other functions are still
|
|
turned off if parameters do not fit entirely in registers).
|
|
- Fixed name-capture bug in function inlining.
|
|
- Improved spilling/reloading strategy for conditionals.
|
|
- IA32, Alpha: better alignment of branch targets.
|
|
- Removed spurious dependency on the -lcurses library.
|
|
|
|
Toplevel environment:
|
|
- Revised handling of top-level value definitions, allows reclaimation
|
|
of definitions that are shadowed by later definitions with the same names.
|
|
(E.g. "let x = <big list>;; let x = 1;;" allows <big list> to be reclaimed.)
|
|
- Revised the tracing facility so that for standard library functions,
|
|
only calls from user code are traced, not calls from the system.
|
|
- Added a "*" prompt when within a comment.
|
|
|
|
Runtime system:
|
|
- Fixed portability issue on bcopy() vs memmove(), affecting Linux RedHat 7.0
|
|
in particular.
|
|
- Structural comparisons (=, <>, <, <=, >, >=, compare) reimplemented
|
|
so as to avoid overflowing the C stack.
|
|
- Input/output functions: arrange so that reads and writes on closed
|
|
in_channel or out_channel raise Sys_error immediately.
|
|
|
|
Standard library:
|
|
- Module Gc: changed some counters to float in order to avoid overflow;
|
|
added alarms
|
|
- Module Hashtbl: added Hashtbl.replace.
|
|
- Module Int64: added bits_of_float, float_of_bits (access to IEEE 754
|
|
representation of floats).
|
|
- Module List: List.partition now tail-rec;
|
|
improved memory behavior of List.stable_sort.
|
|
- Module Nativeint: added Nativeint.size (number of bits in a nativeint).
|
|
- Module Obj: fixed incorrect resizing of float arrays in Obj.resize.
|
|
- Module Pervasives: added float constants "infinity", "neg_infinity", "nan";
|
|
added a "classify_float" function to test a float for NaN, infinity, etc.
|
|
- Pervasives.input_value: fixed bug affecting shared custom objects.
|
|
- Pervasives.output_value: fixed size bug affecting "int64" values.
|
|
- Pervasives.int_of_string, {Int32,Int64,Nativeint}.of_string:
|
|
fixed bug causing bad digits to be accepted without error.
|
|
- Module Random: added get_state and set_state to checkpoint the generator.
|
|
- Module Sys: signal handling functions are passed the system-independent
|
|
signal number rather than the raw system signal number whenever possible.
|
|
- Module Weak: added Weak.get_copy.
|
|
|
|
Other libraries:
|
|
- Bigarray: added Bigarray.reshape to take a view of the elements of a
|
|
bigarray with different dimensions or number of dimensions;
|
|
fixed bug causing "get" operations to be unavailable in custom
|
|
toplevels including Bigarray.
|
|
- Dynlink: raise an error instead of crashing when the loaded module
|
|
refers to the not-yet-initialized module performing a dynlink operation.
|
|
- Bytecode threads: added a thread-safe version of the Marshal module;
|
|
fixed a rare GC bug in the thread scheduler.
|
|
- POSIX threads: fixed compilation problem with threads.cmxa.
|
|
- Both thread libraries: better tail-recursion in Event.sync.
|
|
- Num library: fixed bug in square roots (Nat.sqrt_nat, Big_int.sqrt_big_int).
|
|
|
|
Tools:
|
|
- ocamldep: fixed missing dependencies on labels of record patterns and
|
|
record construction operations
|
|
|
|
Win32 port:
|
|
- Unix.waitpid now implements the WNOHANG option.
|
|
|
|
Mac OS ports:
|
|
- Mac OS X public beta is supported.
|
|
- Int64.format works on Mac OS 8/9.
|
|
|
|
|
|
Objective Caml 3.00 (25 Apr 2000):
|
|
----------------------------------
|
|
|
|
Language:
|
|
- OCaml/OLabl merger:
|
|
* Support for labeled and optional arguments for functions and classes.
|
|
* Support for variant types (sum types compared by structure).
|
|
See tutorial (chapter 2 of the OCaml manual) for more information.
|
|
- Syntactic change: "?" in stream error handlers changed to "??".
|
|
- Added exception renaming in structures (exception E = F).
|
|
- (OCaml 2.99/OLabl users only) Label syntax changed to preserve
|
|
backward compatibility with 2.0x (labeled function application
|
|
is f ~lbl:arg instead of f lbl:arg). A tool is provided to help
|
|
convert labelized programs to OCaml 3.00.
|
|
|
|
Both compilers:
|
|
- Option -labels to select commuting label mode (labels are mandatory,
|
|
but labeled arguments can be passed in a different order than in
|
|
the definition of the function; in default mode, labels may be omitted,
|
|
but argument reordering is only allowed for optional arguments).
|
|
- Libraries (.cma and .cmxa files) now "remember" C libraries given
|
|
at library construction time, and add them back at link time.
|
|
Allows linking with e.g. just unix.cma instead of
|
|
unix.cma -custom -cclib -lunix
|
|
- Revised printing of error messages, now use Format.fprintf; no visible
|
|
difference for users, but could facilitate internationalization later.
|
|
- Fixed bug in unboxing of records containing only floats.
|
|
- Fixed typing bug involving applicative functors as components of modules.
|
|
- Better error message for inconsistencies between compiled interfaces.
|
|
|
|
Bytecode compiler:
|
|
- New "modular" format for bytecode executables; no visible differences
|
|
for users, but will facilitate further extensions later.
|
|
- Fixed problems in signal handling.
|
|
|
|
Native-code compiler:
|
|
- Profiling support on x86 under FreeBSD
|
|
- Open-coding and unboxing optimizations for the new integer types
|
|
int32, int64, nativeint, and for bigarrays.
|
|
- Fixed instruction selection bug with "raise" appearing in arguments
|
|
of strict operators, e.g. "1 + raise E".
|
|
- Better error message when linking incomplete/incorrectly ordered set
|
|
of .cmx files.
|
|
- Optimized scanning of global roots during GC, can reduce total running
|
|
time by up to 8% on GC-intensive programs.
|
|
|
|
Interactive toplevel:
|
|
- Better printing of exceptions, including arguments, when possible.
|
|
- Fixed rare GC bug occurring during interpretation of scripts.
|
|
- Added consistency checks between interfaces and implementations
|
|
during #load.
|
|
|
|
Run-time system:
|
|
- Added support for "custom" heap blocks (heap blocks carrying
|
|
C functions for finalization, comparison, hashing, serialization
|
|
and deserialization).
|
|
- Support for finalisation functions written in Caml.
|
|
|
|
Standard library:
|
|
- New modules Int32, Int64, Nativeint for 32-bit, 64-bit and
|
|
platform-native integers
|
|
- Module Array: added Array.sort, Array.stable_sort.
|
|
- Module Gc: added Gc.finalise to attach Caml finalisation functions to
|
|
arbitrary heap-allocated data.
|
|
- Module Hashtbl: do not bomb when resizing very large table.
|
|
- Module Lazy: raise Lazy.Undefined when a lazy evaluation needs itself.
|
|
- Module List: added List.sort, List.stable_sort; fixed bug in List.rev_map2.
|
|
- Module Map: added mapi (iteration with key and data).

|
|
a module component, both sharing an abstract type.
|
|
- Bug involving recursive classes constrained by a class type fixed.
|
|
- Fixed bugs in printing class types and in printing unification errors.
|
|
|
|
* Compilation:
|
|

|
|
so as to avoid code size explosion.
|

|
* Native-code compiler:
|
|
- Better constant propagation in boolean expressions and in conditionals.
|
|
- Removal of unused arguments during function inlining.
|
|

|
- Revised compilation scheme for definitions at top level of compilation
|
|
units, so that top level functions have no free variables.
|
|
- Coalesced multiple allocations of heap blocks inside one expression
|
|
(e.g. x :: y :: z allocates the two conses in one step).
|
|

|
|
- MIPS: fixed wrong asm generated for String.length "literal".
|
|
|
|
* Standard library:
|
|
- Added the "ignore" primitive function, which just throws away its
|
|
argument and returns "()". It allows to write
|
|
"ignore(f x); y" if "f x" doesn't have type unit and you don't
|
|
want the warning caused by "f x; y".

|
* The ocamldep dependency generator: now performs full parsing of the
|
|
sources, taking into account the scope of module bindings.
|
|
|
|
* The ocamlyacc parser generator: fixed sentinel error causing wrong
|
|
tables to be generated in some cases.
|
|
|
|
* The str library:
|
|
- Added split_delim, full_split as variants of split that control
|
|
more precisely what happens to delimiters.

|
|
- Bypass color lookup for 16 bpp and 32 bpp direct-color displays.
|
|
- Larger color cache.
|
|
|
|
* The thread library:
|
|
- Bytecode threads: more clever use of non-blocking I/O, makes I/O
|
|
operations faster.
|
|
- POSIX threads: gcc-ism removed, should now compile on any ANSI C compiler.

|
|
|
|
|
|

allow running "atom" and "pixie" on ocamlopt-generated binaries.
|
|
- Intel x86: use movzbl and movsbl systematically to load 8-bit and 16-bit

|
|
- Better printing of uncaught exceptions.

|
|
unmatched opening parenthesis on missing closing parenthesis).
|
|
- Check consistency between interfaces (.cmi).
|
|
- Revised rules for determining dependencies between modules.
|
|
- Options "-verbose" for printing calls to C compiler, "-noassert"
|
|
for turning assertion checks off.

- Filename: "is_absolute" is superseded by "is_implicit" and "is_relative".
|
|
To adapt old programs, change "is_absolute x" to "not (is_implicit x)"
|
|
(but the new "is_relative" is NOT the opposite of the old "is_absolute").
|
|
- Array, Hashtbl, List, Map, Queue, Set, Stack, Stream:
|
|
the "iter" functions now take as argument a unit-returning function.
|
|
- Format: added "printf" interface to the formatter (see the documentation).
|
|
Revised behaviour of simple boxes: no more than one new line is output
|
|
when consecutive break hints should lead to multiple line breaks.
|
|
- Stream: revised implementation, renamed Parse_failure to Failure and
|
|
Parse_error to Error (don't you love gratuitous changes?).
|
|
- String: added index, rindex, index_from, rindex_from.
|
|
- Array: added mapi, iteri, fold_left, fold_right, init.
|
|
- Added Map.map, Set.subset, Printexc.to_string.
|

|
|
modules.
|
|
- Numerous small fixes.
|

|
|
now supported by the native-code compiler.
|
|
- dbm and graph: work in native code.
|
|
- num: fixed bug in Nat.nat_of_string.
|
|
- str: fixed deallocation bug with case folding.
|
|
- win32unix: use Win32 handles instead of (buggy) VC++ emulation of Unix

|
* Standard library:
|
|
- More floating-point functions (all ANSI C float functions now available).
|
|

|
|
----------------------------------
|
|
|
|
* Typing:
|
|
- bug with type names escaping their scope via unification with
|
|
non-generalized type variables '_a completely fixed;
|
|
- fixed bug in occur check : it was too restrictive;
|
|
- fixed bug of coercion operators;
|
|
- check that no two types of the same name are generated in a module
|
|
(there was no check for classes);
|
|
- "#install_printer" works again;

|
- fixed bug in printing of subtyping errors;
|
|
- in class interfaces, construct "method m" (without type) change
|
|
the status of method m from abstract to concrete;
|
|
- in a recursive definition of class interfaces, a class can now
|
|
inherit from a previous class;
|
|
- typing of a method make use of an eventual previously given type
|
|
of this method, yielding clearer type errors.
|
|
|
|
* Compilation (ocamlc and ocamlopt):
|
|
- fixed bug in compilation of classes.
|
|
|
|
* Native-code compilation:

- code emitter for the Motorola 680x0 processors (retrocomputing week);
|
|
- Alpha/OSF1: generate frame descriptors, avoids crashes when e.g.
|
|
exp() or log() cause a domain error; fixed bug with
|
|
String.length "literal";
|
|
- Sparc, Mips, HPPA: removed marking of scanned stack frames
|
|
(benefits do not outweight cost).
|
|
|
|
* Standard library:
|
|
- Arg.parse now prints documentation for command-line options;
|
|

|
|
|
|
|
|
Objective Caml 1.02 (27 Sep 1996):
|
|
----------------------------------
|
|
|
|
* Typing:
|
|
- fixed bug with type names escaping their scope via unification
|
|
with non-generalized type variables '_a;
|
|
- keep #class abbreviations longer;
|
|
- faster checking of well-formed abbreviation definitions;
|
|
- stricter checking of "with" constraints over signatures (arity
|
|
mismatch, overriding of an already manifest type).
|
|
|
|
* Compilation (ocamlc and ocamlopt):
|
|
- fixed bug in compilation of recursive classes;
|
|
- [|...|] and let...rec... allowed inside definitions of recursive
|
|
data structures;
|
|
|
|
* Bytecode compilation: fixed overflow in linker for programs with
|
|
more than 65535 globals and constants.
|
|
|
|
* Native-code compilation:
|
|
- ocamlopt ported to HPPA under HP/UX, Intel x86 under Solaris 2,
|
|
PowerMacintosh under MkLinux;
|
|
- fixed two bugs related to floating-point arrays (one with "t array"
|
|
where t is an abstract type implemented as float, one with
|
|
comparison between two float arrays on 32 bit platforms);
|
|
- fixed reloading/spilling problem causing non-termination of
|
|
register allocation;
|
|
- fixed bugs in handling of () causing loss of tail recursion;
|
|
- fixed reloading bug in indirect calls.
|
|
|
|
* Windows NT/95 port:
|
|
- complete port of the threads library (Pascal Cuoq);
|
|

|
|
|
* Standard library:
|
|
- bug in in List.exists2 fixed;
|
|
- bug in "Random.int n" for very large n on 64-bit machines fixed;
|
|
- module Format: added a "general purpose" type of box (open_box);
|
|
can output on several formatters at the same time.
|
|
|
|
* The "threads" library:
|
|
- implementation on top of native threads available for Win32 and
|
|
POSIX 1003.1c;
|
|
- added -thread option to select a thread-safe version of the
|
|
standard library, the ThreadIO module is no longer needed.
|
|
|
|
* The "graph" library: avoid invalid pixmaps when doing
|
|
open_graph/close_graph several times.
|
|
|
|
* The "dynlink" library: support for "private" (no re-export) dynamic loading.
|
|
|
|
* ocamlyacc: skip '...' character literals correctly.
|
|
|
|
* C interface: C code linked with O'Caml code can provide its own main()
|
|
and call caml_main() later.
|
|
|
|
|
|
Objective Caml 1.01 (12 Jun 1996):
|
|
----------------------------------
|
|
|
|
* Typing: better report of type incompatibilities;
|
|
non-generalizable type variables in a struct...end no longer flagged
|
|
immediately as an error;
|
|
name clashes during "open" avoided.
|
|
|
|
* Fixed bug in output_value where identical data structures
|
|
could have different external representations; this bug caused wrong
|
|
"inconsistent assumptions" errors when checking compatibility of
|
|
interfaces at link-time.
|
|
|
|
* Standard library: fixed bug in Array.blit on overlapping array sections
|
|
|
|

|
|
an implementation/an interface, regardless of file extension;
|
|
overflow bug on wide-range integer pattern-matchings fixed.
|
|
|
|
* ocamlc: fixed bytecode generation bug causing problems with compilation
|
|
units defining more than 256 values
|
|
|
|
* ocamlopt, all platforms:
|
|
fixed GC bug in "let rec" over data structures;
|
|
link startup file first, fixes "undefined symbol" errors with some
|
|
libraries.
|
|
|
|
* ocamlopt, Intel x86:
|
|
more efficient calling sequence for calling C functions;
|
|
floating-point wars, chapter 5: don't use float stack for holding
|
|
float pseudo-registers, stack-allocating them is just as efficient.
|
|
|
|
* ocamlopt, Alpha and Intel x86: more compact calling sequence for garbage
|
|
collection.
|
|
|
|
* ocamllex: generated automata no longer use callbacks for refilling
|
|
the input buffer (works better with threads); character literals
|
|
correctly skipped inside actions.
|
|
|
|
* ocamldep: "-I" directories now searched in the right order
|
|
|
|
* Thread library: incompatibilities with callbacks, signals, and
|
|
dynamic linking removed; scheduling bug with Thread.wait fixed.
|
|
|
|

|
---------------------------------
|
|
|
|
* Merge of Jerome Vouillon and Didier Remy's object-oriented
|
|
extensions.
|
|
|
|
* All libraries: all "new" functions renamed to "create" because "new"
|
|
is now a reserved keyword.
|
|
|
|
* Compilation of "or" patterns (pat1 | pat2) completely revised to
|
|
avoid code size explosion.
|
|
|
|
* Compiler support for preprocessing source files (-pp flag).
|
|
|
|
* Library construction: flag -linkall to force linking of all units in
|
|
a library.
|
|
|
|
* Native-code compiler: port to the Sparc under NetBSD.
|
|
|
|
* Toplevel: fixed bug when tracing several times the same function
|
|
under different names.
|
|
|
|
* New format for marshaling arbitrary data structures, allows
|
|
marshaling to/from strings.
|
|
|

|
* Dynlink library: added support for linking libraries (.cma files).
|
|
|
|
Caml Special Light 1.15 (15 Mar 1996):
|
|
--------------------------------------
|
|
|
|
* Caml Special Light now runs under Windows NT and 95. Many thanks to
|
|
Kevin Gallo (Microsoft Research) who contributed his initial port.
|
|
|
|
* csllex now generates tables for a table-driven automaton.
|
|
The resulting lexers are smaller and run faster.
|
|
|
|
* Completely automatic configuration script.
|
|
|
|
* Typing: more stringent checking of module type definitions against
|
|
manifest module type specifications.
|
|
|
|
* Toplevel: recursive definitions of values now working.
|
|
|
|
* Native-code compiler, all platforms:
|
|
toplevel "let"s with refutable patterns now working;
|
|
fixed bug in assignment to float record fields;
|
|
direct support for floating-point negation and absolute value.
|
|
|
|
* Native-code compiler, x86: fixed bug with tail calls (with more than
|
|
4 arguments) from a function with a one-word stack frame.
|
|
|
|
* Native-code compiler, Sparc: problem with -compact fixed.
|
|
|
|

|
|
-------------------------------------
|
|

|
* cslopt ported to the PowerPC/RS6000 architecture. Better support for
|
|
AIX in the bytecode system as well.
|
|
|
|
* cslopt, all platforms: fixed bug in live range splitting around catch/exit.
|
|
|
|
* cslopt for the Intel (floating-point wars, chapter 4):
|
|
implemented Ershov's algorithm to minimize floating-point stack usage;
|
|
out-of-order pops fixed.
|
|
|
|
* Several bug fixes in callbacks and signals.
|
|
|
|
Caml Special Light 1.13 (4 Jan 1996):
|
|
-------------------------------------
|
|
|
|
* Pattern-matching compilation revised to factor out accesses inside
|
|
matched structures.
|
|
|
|
* Callbacks and signals now supported in cslopt.
|
|
Signals are only detected at allocation points, though.
|
|
Added callback functions with 2 and 3 arguments.
|
|
|
|
* More explicit error messages when a native-code program aborts due
|
|
to array or string bound violations.
|
|
|
|
* In patterns, "C _" allowed even if the constructor C has several arguments.
|
|
|
|
* && and || allowed as alternate syntax for & and or.
|
|
|
|
* cslopt for the Intel: code generation for floating-point
|
|
operations entirely redone for the third time (a pox on whomever at
|
|
Intel decided to organize the floating-point registers as a stack).
|
|
|
|
* cslopt for the Sparc: don't use Sparc V8 smul and sdiv instructions,
|
|
emulation on V7 processors is abysmal.
|
|
|
|
Caml Special Light 1.12 (30 Nov 1995):
|
|
--------------------------------------
|
|
|
|
* Fixed an embarrassing bug with references to floats.

|
Caml Special Light 1.11 (29 Nov 1995):
|
|
--------------------------------------
|
|
|
|
* Streams and stream parsers a la Caml Light are back (thanks to
|
|
Daniel de Rauglaudre).
|
|
|
|
* User-level concurrent threads, with low-level shared memory primitives
|
|
(locks and conditions) as well as channel-based communication primitives
|
|
with first-class synchronous events, in the style of Reppy's CML.
|
|
|
|
* The native-code compiler has been ported to the HP PA-RISC processor
|
|
running under NextStep (sorry, no HPUX, its linker keeps dumping
|
|
core on me).
|
|
|
|
* References not captured in a function are optimized into variables.
|
|
|
|
* Fixed several bugs related to exceptions.
|
|
|
|
* Floats behave a little more as specified in the IEEE standard
|
|
(believe it or not, but x < y is not the negation of x >= y).
|
|
|
|
* Lower memory consumption for the native-code compiler.
|
|
|
|
Caml Special Light 1.10 (07 Nov 1995):
|
|
--------------------------------------
|
|
|
|
* Many bug fixes (too many to list here).
|
|
|
|

|
|
signatures for concise sharing of all type components of a signature;
|
|
better support for concrete types in signatures.
|
|
|
|
* Native-code compiler: the Intel 386 version has been ported to
|
|
NextStep and FreeBSD, and generates better code (especially for
|
|
floats)
|
|
|
|
* Tools and libraries: the Caml Light profiler and library for
|
|
arbitrary-precision arithmetic have been ported (thanks to John
|
|
Malecki and Victor Manuel Gulias Fernandez); better docs for the Unix
|
|
and regexp libraries.
|
|
|
|

|
|
no calls to ranlib in Solaris
|
|
|
