(Changes that can break existing programs are marked with a "*")
|
|
|
|
Language features:
|
|
- Attributes and extension nodes
|
|
- Generative functors
|
|
- Module aliases
|
|
|
|
Build system for the OCaml distribution:
|
|
- Use -bin-annot when building.
|
|
|
|
Camlp4:
|
|
- Removed from the official distribution
|
|
|
|
Other libraries:
|
|
* Labltk: removed from the distribution, now available as a third-party library
|
|
|
|
Type system:
|
|
* Keep typing of pattern cases independent in principal mode
|
|
(i.e. information from previous cases is no longer used when typing
|
|
patterns; cf. PR6235' in typing-warnings/records.ml)
|
|
- 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
|
|
* Module aliases are now typed in a specific way, which remembers their
|
|
identity. In particular this changes the signature inferred by
|
|
"module type of"
|
|
- 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.
|
|
- PR#6333: Compare first class module types structurally rather than
|
|
nominally. Value subtyping allows module subtyping as long as the internal
|
|
representation is unchanged.
|
|
|
|

OCaml 4.01.0:
|
|
-------------
|
|
|
|
(Changes that can break existing programs are marked with a "*")
|
|
|
|
Other libraries:
|
|
- Labltk: updated to Tcl/Tk 8.6.
|
|
|
|
Type system:
|
|
- PR#5759: use well-disciplined type information propagation to
|
|
disambiguate label and constructor names
|
|
(Jacques Garrigue, Alain Frisch and Leo P. 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.
|
|
(Jacques Garrigue)
|
|
* PR#6035: Reject multiple declarations of the same method or instance variable
|
|
in an object
|
|
(Alain Frisch)
|
|
|
|
Compilers:
|
|
- PR#5861: raise an error when multiple private keywords are used in type
|
|
declarations
|
|
(Hongbo Zhang)
|
|
- PR#5634: parsetree rewriter (-ppx flag)

|
|
- PR#5768: On "unbound identifier" errors, use spell-checking to suggest names
|
|
present in the environment
|
|
(Gabriel Scherer)
|
|
- ocamlc has a new option -dsource to visualize the parsetree
|
|
(Alain Frisch, Hongbo Zhang)
|
|
- tools/eqparsetree compares two parsetree ignoring location
|
|
(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.
|
|
(Xavier Leroy)
|
|
- 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:
|
|
- ISO-latin1 characters in identifiers
|
|
- uses of the (&) and (or) operators instead of (&&) and (||)
|
|

|
|
|
Standard library:
|
|

|
|
Printexc.get_callstack
|
|
(Gabriel Scherer, Jacques-Henri Jourdan, Alain Frisch)
|
|
- PR#5986: new flag Marshal.Compat_32 for the serialization functions
|
|
(Marshal.to_*), forcing the output to be readable on 32-bit hosts.
|
|
(Xavier Leroy)
|
|
- infix application operators |> and @@ in Pervasives
|
|
(Fabrice Le Fessant)

|
|
file descriptor is created in close-on-exec mode
|
|
(Xavier Leroy)
|
|
|
|
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)
|
|
|
|
Internals:
|
|
- Moved debugger/envaux.ml to typing/envaux.ml to publish env_of_only_summary
|
|
as part of compilerlibs, to be used on bin-annot files.
|
|
(Fabrice Le Fessant)
|
|
- The test suite can now be run without installing OCaml first.

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 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.
|
|
|

|
|
Objective Caml 3.12.0:
|
|
----------------------
|
|
|
|
(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)

|
|
|
|
Ocamlbuild:
|
|
- Add support for native dynlink.
|
|
|
|
New tool:

|
|
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.

Objective Caml 3.11.0:
|
|
----------------------
|
|
|
|
(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.
|
|
|
|

|
|

|
|
out-of-heap pointers.

Objective Caml 3.10.0:
|
|
----------------------
|
|
|
|
(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:
|
|
----------------------
|
|
|
|
(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.
|
|
|
|
Objective Caml 3.08.4:

Objective Caml 3.08.3:
|
|
----------------------
|
|
|
|
New features:
|
|
- support for ocamlopt -pack under Mac OS X (PR#2634, PR#3320)
|
|
- ignore unknown warning options for forward and backward compatibility
|
|
- runtime: export caml_compare_unordered (PR#3479)

|
|
- ocamldoc: add -man-section option
|
|
- labltk: add the "solid" relief option (PR#3343)
|
|
|
|
Bug fixes:
|
|
- 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)
|

|
|
- camlp4: incorrect line numbers in errors (PR#3188)
|
|
- emacs: xemacs-specific code, wrong call to "sit-for"

|
|
|
|
|
|
Objective Caml 3.08.1:
|
|
----------------------
|
|
|
|
Licence:
|
|
- The emacs files are now under GPL
|
|
- Slightly relaxed some conditions of the QPL
|
|
|
|
Bug fixes:

Objective Caml 3.08.0:
|
|
----------------------
|
|
|
|
(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 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.
|
|
|
|

|
|
- See camlp4/CHANGES and camlp4/ICHANGES for more info.
|
|
|
|
|
|
Objective Caml 3.07:
|
|
--------------------
|
|
|
|
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.
|
|

|
|
- 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,
|
|

|
|
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.
|
|

|
|
|
|
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.

|
|
(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.
|
|
|

- 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:
|
|
--------------------------
|
|
|
|
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:
|
|
--------------------
|
|
|
|
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:
|
|
--------------------
|
|
|
|
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:
|
|
--------------------
|
|
|
|
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).
|
|
- Module Set: added iterators for_all, exists, filter, partition.
|
|
- Module Sort: still here but deprecated in favor of new sorting functions
|
|
in Array and List.
|
|
- Module Stack: added Stack.top
|
|
- Module String: fixed boundary condition on String.rindex_from
|
|
- Added labels on function arguments where appropriate.
|
|
|
|
New libraries and tools:
|
|
- ocamlbrowser: graphical browser for OCaml sources and compiled interfaces,
|
|
supports cross-referencing, editing, running the toplevel.
|
|
- LablTK: GUI toolkit based on TK, using labeled and optional arguments,
|
|
easier to use than CamlTK.
|
|
- Bigarray: large, multi-dimensional numerical arrays, facilitate
|
|
interfacing with C/Fortran numerical code, efficient support for
|
|
advanced array operations such as slicing and memory-mapping of files.
|
|
|
|
Other libraries:
|
|
- Bytecode threads: timer-based preemption was broken, works back again;
|
|
fixed bug in Pervasives.input_line; exported Thread.yield.
|
|
- System threads: several GC / reentrancy bugs fixed in buffered I/O
|
|
and Unix I/O; revised Thread.join implementation for strict POSIX
|
|
conformance; exported Thread.yield.
|
|
- Graphics: added support for double buffering; added, current_x, current_y,
|
|
rmoveto, rlineto, and draw_rect.
|
|
- Num: fixed bug in Num.float_of_num.
|
|
- Str: worked around potential symbol conflicts with C standard library.
|
|
- Dbm: fixed bug with Dbm.iter on empty database.
|
|
|
|
New or updated ports:
|
|
- Alpha/Digital Unix: lifted 256M limitation on total memory space
|
|
induced by -taso

later if there's a demand.
|
|
- Added a new tool, ocamlmkappli, to build an application from a
|
|
program written in O'Caml.
|
|
|
|
|
|

--------------------
|
|
|
|
- C interface: corrected inconsistent change in the CAMLparam* macros.
|
|
- Fixed internal error in ocamlc -g.
|

abbreviating another module type name.
|
|
- ocamldep: fixed stdout/stderr mismatch after failing on one file.
|
|
- Random.self_init more random.
|
|
- Windows port:
|
|
- Toplevel application: fixed spurious crash on exit.
|
|
- Native-code compiler: fixed bug in assembling certain
|
|
floating-point constants (masm doesn't grok 2e5, wants 2.0e5).
|
|
|
|
Objective Caml 2.03:
|
|
--------------------
|
|
|
|
New ports:
|
|
- Ported to BeOS / Intel x86 (bytecode and native-code).
|
|
- BSD / Intel x86 port now supports both a.out and ELF binary formats.
|
|
- Added support for {Net,Open}BSD / Alpha.
|
|
- Revamped Rhapsody port, now works on MacOS X server.
|
|
|
|
Syntax:
|
|
- Warning for "(*)" and "*)" outside comment.
|
|
- Removed "#line LINENO", too ambiguous with a method invocation;
|
|
the equivalent "# LINENO" is still supported.
|
|
|
|
Typing:
|
|
- When an incomplete pattern-matching is detected, report also a
|
|
value or value template that is not covered by the cases of
|
|
the pattern-matching.
|
|
- Several bugs in class type matching and in type error reporting fixed.
|
|
- Added an option -rectypes to support general recursive types,
|
|
not just those involving object types.
|
|
|
|
Bytecode compiler:
|
|
- Minor cleanups in the bytecode emitter.
|
|
- Do not remove "let x = y" bindings in -g mode; makes it easier to
|
|
debug the code.
|
|
|
|
Native-code compiler:
|
|
- Fixed bug in grouping of allocations performed in the same basic block.
|
|
- Fixed bug in constant propagation involving expressions containing
|
|
side-effects.
|
|
- Fixed incorrect code generation for "for" loops whose upper bound is
|
|
a reference assigned inside the loop.
|
|
- MIPS code generator: work around a bug in the IRIX 6 assembler.
|
|
|
|
Toplevel:
|
|
- Fixed incorrect redirection of standard formatter to stderr
|
|
while executing toplevel scripts.
|
|
|
|
Standard library:
|
|
- Added List.rev_map, List.rev_map2.
|
|
- Documentation of List functions now says which functions are
|
|
tail-rec, and how much stack space is needed for non-tailrec functions.
|
|
- Wrong type for Printf.bprintf fixed.
|
|
- Fixed weird behavior of Printf.sprintf and Printf.bprintf in case of
|
|
partial applications.
|

|
|
- Sort.array: serious bugs fixed.
|
|
- Stream.count: fixed incorrect behavior with ocamlopt.
|
|
|
|
Run-time system and external interface:
|
|
- Fixed weird behavior of signal handlers w.r.t. signal masks and exceptions
|
|
raised from the signal handler.
|
|
- Fixed bug in the callback*_exn() functions.
|
|
|
|
Debugger:
|
|
- Fixed wrong printing of float record fields and elements of float arrays.
|
|
- Supports identifiers starting with '_'.
|
|
|
|
Profiler:
|
|
- Handles .mli files, so ocamlcp can be used to replace ocamlc (e.g. in a
|
|
makefile).
|
|
- Now works on programs that use stream expressions and stream parsers.
|
|
|
|
Other libraries:
|
|
- Graphics: under X11, treat all mouse buttons equally; fixed problem
|
|
with current font reverting to the default font when the graphics
|
|
window is resized.
|
|
- Str: fixed reentrancy bugs in Str.replace and Str.full_split.
|
|
- Bytecode threads: set standard I/O descriptors to non-blocking mode.

Objective Caml 2.02:
|
|
--------------------
|
|
|
|
* Type system:
|
|
- Check that all components of a signature have unique names.
|
|
- Fixed bug in signature matching involving a type component and
|
|
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:
|
|
- Changed compilation scheme for "{r with lbl = e}" when r has many fields
|
|
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.
|
|
- Eliminated redundant tagging/untagging in bit shifts.
|
|
- Static allocation of closures for functions without free variables,
|
|
reduces the size of initialization code.
|
|
- 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).
|
|
- Ix86: better handling of large integer constants in instruction selection.
|
|
- 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".
|
|
- Added the "Buffer" module (extensible string buffers).
|
|
- Module Format: added formatting to buffers and to strings.
|
|
- Added "mem" functions (membership test) to Hashtbl and Map.
|
|
- Module List: added find, filter, partition.
|
|
Renamed remove and removeq to remove_assoc and remove_assq.
|
|
- Module Marshal: fixed bug in marshaling functions when passed functional
|
|
values defined by mutual recursion with other functions.
|
|
- Module Printf: added Printf.bprintf (print to extensible buffer);
|
|
added %i format as synonymous for %d (as per the docs).
|
|
- Module Sort: added Sort.array (Quicksort).
|
|
|
|
* Runtime system:
|
|
- New callback functions for callbacks with arbitrary many arguments
|
|
and for catching Caml exceptions escaping from a callback.
|
|
|
|
* 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.
|
|
- Added replace_matched for separate matching and replacement operations.
|
|
|
|
* The graphics library:
|
|
- 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.
|
|
- Both: avoid memory leak in the Event module when a communication
|
|
offer is never selected.
|
|
|
|
* The Unix library:
|
|

|
|
|
|
* The DBM library: no longer crashes when calling Dbm.close twice.
|
|
|
|
* Emacs mode:
|
|
- Updated with Garrigue and Zimmerman's latest version.
|
|
- Now include an "ocamltags" script for using etags on OCaml sources.
|
|
|
|
* Win32 port:
|
|
- Fixed end-of-line bug in ocamlcp causing problems with generated sources.
|
|
|
|
|
|
Objective Caml 2.01:
|

|
|
|
|

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

|
|
- Alpha: $gp handling revised to follow Alpha's standard conventions,
|
|
allow running "atom" and "pixie" on ocamlopt-generated binaries.
|
|
- Intel x86: use movzbl and movsbl systematically to load 8-bit and 16-bit

|
as lowercase idents).
|
|
|
|
* Objects:
|
|
- Added "protected" methods (visible only from subclasses, can be hidden
|
|
in class type declared in module signature).
|
|
- Objects can be compared using generic comparison functions.
|
|
- Fixed compilation of partial application of object constructors.
|
|
|
|
* Type system:
|
|
- Occur-check now more strict (all recursions must traverse an object).
|

unmatched opening parenthesis on missing closing parenthesis).
|
|
- Check consistency between interfaces (.cmi).
|
|

|
|
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.

|
|
|
* 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:
|
|
- optimization of functions taking tuples of arguments;
|
|
- 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;
|
|
- I/O buffers (types in_channel and out_channel) now heap-allocated,
|
|
avoids crashing when closing a channel several times;
|
|
- Overflow bug in compare() fixed;
|
|
- GC bug in raising Sys_error from I/O functions fixed;
|
|
- Parsing.symbol_start works even for epsilon productions.
|
|
|
|
* Foreign interface: main() in C now working, fixed bug in library
|
|
order at link time.
|
|
|
|
* Thread library: guard against calling thread functions before Thread.create.
|
|
|
|
* Unix library: fixed getsockopt, setsockopt, open_process_{in,out}.
|
|
|
|
* Perl-free, cpp-free, cholesterol-free installation procedure.
|
|
|
|
|
|
Objective Caml 1.02:
|
|
--------------------
|
|
* 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);
|
|
- partial port of the Unix library (Pascal Cuoq);
|
|
- expansion of *, ? and @ on the command line.
|
|
|
|
* 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:
|
|
--------------------
|
|
* 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
|
|
|
|
* Unmarshaling from strings now working.
|
|
|
|
* ocamlc, ocamlopt: new flags -intf and -impl to force compilation as
|
|
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.
|
|
|
|
* New "dbm" library, interfaces with NDBM.
|
|
|
|
* Object-oriented extensions:
|
|
instance variables can now be omitted in class types;
|
|
some error messages have been made clearer;
|
|
several bugs fixes.
|
|
|
|
Objective Caml 1.00:
|
|
--------------------
|
|
|
|
* 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.
|
|
|
|
* Standard library: new module Genlex (configurable lexer for streams)
|
|
|
|
* Thread library: much better support for I/O and blocking system calls.
|
|
|
|
* Graphics library: faster reclaimation of unused pixmaps.
|
|
|
|
* Unix library: new functions {set,clear}_nonblock, {set,clear}_close_on_exec,
|
|
{set,get}itimer, inet_addr_any, {get,set}sockopt.
|
|
|
|
* Dynlink library: added support for linking libraries (.cma files).
|
|
|
|
Caml Special Light 1.15:
|
|
------------------------
|
|
|
|
* 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.
|
|
|
|
* Thread library: support for non-blocking writes; scheduler revised.
|
|
|
|
* Unix library: bug in gethostbyaddr fixed; bounds checking for read,
|
|
write, etc.
|
|
|
|
Caml Special Light 1.14:
|
|
------------------------
|
|
|
|
* 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:
|
|
------------------------
|
|
|
|
* 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:
|
|
------------------------
|
|
|
|
* Fixed an embarrassing bug with references to floats.
|
|
|
|
Caml Special Light 1.11:
|
|
------------------------
|
|
|
|
* 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:
|
|
------------------------
|
|
|
|
* Many bug fixes (too many to list here).
|
|
|
|
* Module language: introduction of a "with module" notation over
|
|
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.
|
|
|
|
Caml Special Light 1.07:
|
|
------------------------
|
|
|
|
* Syntax: optional ;; allowed in compilation units and structures
|
|
(back by popular demand)
|
|
|
|
* cslopt:
|
|
generic handling of float arrays fixed
|
|
direct function application when the function expr is not a path fixed
|
|
compilation of "let rec" over values fixed
|
|
multiple definitions of a value name in a module correctly handled
|
|
no calls to ranlib in Solaris
|
|
|
|
* csltop: #trace now working
|
|
|
|
* Standard library: added List.memq; documentation of Array fixed.
|
|
|
|
Caml Special Light 1.06:
|
|
------------------------
|
|
|
|
* First public release.
