Objective Caml 3.03:
|
|
--------------------
|
|
|
|
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.
|
|
To help porting, Hashtbl, Map and Set are also available in MoreLabels.
|
|
- 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.
|
|
- Allowed coercing self to the type of the current class, avoiding
|
|
an obscure error message about "Self type cannot be unified..."
|
|
|
|
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.
|
|
|
|
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.
|
|
- ocamlyacc: added parser debugging support (set OCAMLRUNPARAM=p to get
|
|
a trace of the pushdown automaton actions).
|
|
|
|
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.
|
|
- On uncaught exception, flush output channels before printing exception
|
|
message and backtrace.
|
|
|
|
Standard library:
|
|
- Added Pervasives.flush_all to flush all opened output channels.
|
|
- 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.
|
|
|
|
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.
|
|
|
|
|
|
Objective Caml 2.04:
|
|
--------------------
|
|
|
|
- C interface: corrected inconsistent change in the CAMLparam* macros.
|
|
- Fixed internal error in ocamlc -g.
|
|

|
|
- 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.
|
|
- Added Random.self_init, which initializes the PRNG from the system date.
|
|
- 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:
|

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).

|
|
values defined by mutual recursion with other functions.

|
|
added %i format as synonymous for %d (as per the docs).
|
|
- Module Sort: added Sort.array (Quicksort).
|
|
|
|
* Runtime system:

|
|
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.

|
|
offer is never selected.

|
|
|
|
* Emacs mode:
|
|
- Updated with Garrigue and Zimmerman's latest version.
|
|

|
- 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:
|
|

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.

|
|
|
|
* Macintosh port:
|
|
- The makefiles are provided for compiling and installing O'Caml on
|
|
a Macintosh with MPW 3.4.1.
|
|
- An application with the toplevel in a window is forthcoming.
|
|
|
|
* Windows NT/95 port: updated toplevel GUI to that of Caml Light 0.73.

|
|
|
|
|
|
Objective Caml 1.03:
|
|
--------------------
|
|
|
|
* 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.
