a new patch to include a -pkgsrc-runtime compilation option. This option is
needed to compile devel/pcre-ocaml due to buildlink shenanigans

also upstream changelog):
Language features:
- Attributes and extension nodes
- Generative functors
- Module aliases
* Alternative syntax for string literals {id|...|id} (can break comments)
- Separation between read-only strings (type string) and read-write byte
sequences (type bytes). Activated by command-line option -safe-string.
Build system for the OCaml distribution:
- Use -bin-annot when building.
- Use GNU make instead of portable makefiles.
- Updated build instructions for 32-bit Mac OS X on Intel hardware.
Shedding weight:
* Removed Camlp4 from the distribution, now available as third-party software.
* Removed Labltk from the distribution, now available as a third-party library.
Type system:
* Keep typing of pattern cases independent in principal mode
- 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"
- Slight change in the criterion to distinguish private
abbreviations and private row types: create a private abbreviation for
closed objects and fixed polymorphic variants.
* Compare first class module types structurally rather than
nominally. Value subtyping allows module subtyping as long as the internal
representation is unchanged.
Compilers:
- More aggressive constant propagation, including float and
int32/int64/nativeint arithmetic. Constant propagation for floats
can be turned off with option -no-float-const-prop, for codes that
change FP rounding modes at run-time.
- New back-end optimization pass: common subexpression elimination (CSE).
(Reuses results of previous computations instead of recomputing them.)
- New back-end optimization pass: dead code elimination.
(Removes arithmetic and load instructions whose results are unused.)
- Optimization of sequences of string patterns
- Experimental native code generator for AArch64 (ARM 64 bits)
- Optimization of integer division and modulus by constant divisors
- Add "-open" command line flag for opening a single module before typing
* "-o" now sets module name to the output file name up to the first "."
(it also applies when "-o" is not given, i.e. the module name is then
the input file name up to the first ".")
* better sharing of structured constants
- new flag to keep locations in cmi files
- issue warning 3 when referring to a value marked with
the [@@ocaml.deprecated] attribute
- a new format implementation based on GADTs
* Constant exception constructors no longer allocate
- avoid unnecessary boxing in let
- Better compilation of optional arguments with default values
- ocamlopt -opaque option for incremental native compilation
Toplevel interactive system:
- New "#show_*" directives
Runtime system:
- New configure option "-no-naked-pointers" to improve performance by
avoiding page table tests during block darkening and the marking phase
of the major GC. In this mode, all out-of-heap pointers must point at
things that look like OCaml values: in particular they must have a valid
header. The colour of said headers should be black.
- Fixed bug in native code version of [caml_raise_with_string] that could
potentially lead to heap corruption.
- Blocks initialized by [CAMLlocal*] and [caml_alloc] are now filled with
[Val_unit] rather than zero.
- Fixed a major performance problem on large heaps (~1GB) by making heap
increments proportional to heap size by default
- Structural equality treats exception specifically
- efficient comparison/indexing of exceptions
- avoid using unsafe C library functions (strcpy, strcat, sprintf)
- An ISO C99-compliant C compiler and standard library is now assumed.
(Plus special exceptions for MSVC.) In particular, emulation code for
64-bit integer arithmetic was removed, the C compiler must support a
64-bit integer type.
Standard library:
* Add new modules Bytes and BytesLabels for mutable byte sequences.
- add List.sort_uniq and Set.of_list
- a faster version of "raise" which does not maintain the backtrace
- support "Unix.kill pid Sys.sigkill" under Windows
- speed improvement for Buffer
- efficient creation of uninitialized float arrays
- Improve documentation regarding finalisers and multithreading
- Trigger warning 3 for all values marked as deprecated in the documentation.
bugfixes, include:
- Labltk: updated to Tcl/Tk 8.6.
Type system:
- use well-disciplined type information propagation to
disambiguate label and constructor names
* 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.
* Reject multiple declarations of the same method or instance variable
in an object
- raise an error when multiple private keywords are used in type
declarations
- parsetree rewriter (-ppx flag)
- ocamldep now supports -absname
- On "unbound identifier" errors, use spell-checking to suggest names
present in the environment
- ocamlc has a new option -dsource to visualize the parsetree
- tools/eqparsetree compares two parsetree ignoring location
- ocamlopt now uses clang as assembler on OS X if available, which enables
CFI support for OS X.
- 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.
- added flag -compat-32 to ocamlc, ensuring that the generated
bytecode executable can be loaded on 32-bit hosts.
- 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
* warning 3 is extended to warn about other deprecated features:
- ISO-latin1 characters in identifiers
- uses of the (&) and (or) operators instead of (&&) and (||)
- Experimental OCAMLPARAM for ocamlc and ocamlopt
- incorrect ordinal number in error message
- add signature to Tstr_include
- expose a way to inspect the current call stack,
Printexc.get_callstack
- new flag Marshal.Compat_32 for the serialization functions
(Marshal.to_*), forcing the output to be readable on 32-bit hosts.
- infix application operators |> and @@ in Pervasives
- add O_CLOEXEC flag to Unix.openfile, so that the returned
file descriptor is created in close-on-exec mode
* 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.
- 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.
- The test suite can now be run without installing OCaml first.
comments.
Updated buildlink3.mk to default to a full dependency (more pertinent in most
cases; usually the standard library needs to be installed for an ocaml
program to run)
Changes from 3.12 to 4.00.1 include:
OCaml 4.00.1:
-------------
Various bug fixes.
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)
- 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
camltoplevel.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.
and various bug fixes.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
* Bug fixes
* New features:
- made configure script work on PlayStation 3
- ARM port: brought up-to-date for Debian 4.0 (Etch)
- many other small changes and bugfixes in camlp4, ocamlbuild, labltk,
emacs files
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
(it currently affects packages using X11, but I guess it will also cause
problems when using pkgviews, for example).
So, instead of fixing it on a package basis, create some wrappers in the
buildlink directory that parse CFLAGS and LDFLAGS contents and convert them
to ocaml flags (basically, prepend -ccopt to each of them).
the missing bits, namely labltk and ocaml-graphics, respectively. To
simplify this, add a Makefile.common. Bump PKGREVISION to 8.
Per discussion with wiz@ a while ago.
- split out the profiled libraries in the PLIST, because they
don't get built on Darwin.
- set INSTALL_UNSTRIPPED on Darwin for both ocaml itself and
anything that directly depends on it, because the ocaml compiler
generates binaries that don't strip properly.
- split patches files
- always enable threading which has various advantages
- it fixes the build of the Tk library
- it greatly simplifies the package list handling
- it provides threading support under NetBSD 1.6/1.6.x
- correct default dependence in "buildlink2.mk" to "build"
Bump package revision because of all these changes.
the normal case when BUILDLINK_DEPENDS.<pkg> isn't specified, it receives
a value only once due to the multiple inclusion protection in the
bulldlink3.mk files. In the case where a package includes several
buildlink3.mk files that each want a slightly different version of another
dependency, having BUILDLINK_DEPENDS.<pkg> be a list allows for the
strictest <pkg> dependency to be matched.
