Bump pkgrevision.
While I'm here: add a comment to patch-at explaining what it does.
Tested by
$ make install
$ cd work/ocaml-3.12.0/testsuite && gmake one DIR=tests/lib-dynlink-native
(Not in a build-env because that uses the wrappers, which don't let the
test suite see the installed OCaml files.)
This is only a workaround on NetBSD/{i386,amd64} for the problems of
OCaml PR#5049 <http://caml.inria.fr/mantis/view.php?id=5049>. (E.g.,
this workaround makes Coccinelle build on those platforms -- but it
still won't build on platforms with native compilation but no native
dynamic loading. Need to hack everything that uses dynlink to have
four compile-time cases -- {yes,no} {byte,nat}dynlink.)
- to do this, and make the result runnable on pre-thumb arm, change
upstreams assembler snippets and stubs to use "mov pc,reg" instead
of the return/call-to-thumb-friendly "bx reg", which is not available
in non-thumb-enabled arm CPUs. Whether this is the way to go, or a
seperate "armt" architecture for ocaml is needed, needs to be discussed
with upstream.
Resulting compiler, when running its selftest suite, has 6 errors less than
the same on i386. Unison compiled natively with this passes its self-test.
natively (that is, only to byte-code).
This consists of two parts:
a) a patch to ocamldoc/Makefile to make it create the man pages using
the interpreted ocamldoc - this exists for both types of architectures,
so is safe. (This will be sent up-stream).
b) move a common shared library file to the common PLIST, and a lot of
files (natively compiled versions of the ML modules and natively compiled
versions of a few binaries) to PLIST.opt.
This has been build-tested on i386 (cross-compiled from amd64) and on
arm. unison builds and works.
"make test" shows the same amount of passed and failed tests (mostly
non-found libraries) as before; but this needs more investigation.
An additional issue to solve (with upstream) is that there's no easy way
to run the part of the test suite that would work on byte-code-only
architectures.
Some of the highlights in release 3.12 are:
* Polymorphic recursion is supported, using explicit type
declarations on the recursively-defined identifiers.
* First-class modules: module expressions can be embedded as
values of the core language, then manipulated like any other
first-class value, then projected back to the module level.
* New operator to modify a signature a posteriori: S with type
t := tau denotes signature S where the t type component is
removed and substituted by the type tau elsewhere.
* New notations for record expressions and record patterns:
{ lbl } as shorthand for { lbl = lbl }, and { ...; _ } marks
record patterns where some labels were intentionally omitted.
* Local open let open ... in ... now supported by popular demand.
* Type variables can be bound as type parameters to functions;
such types are treated like abstract types within the
function body, and like type variables (possibly generalized)
outside.
* The module type of construct enables to recover the module
type of a given module.
* Explicit method override using the method! keyword, with
associated warnings and errors.

- PR#4921: configure option to help cross-compilers
(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.
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.

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

order. Remove "@unexec rmdir" lines made redundant by the reordering.
Also, use a more succinct way to match ${OPSYS} + ${MACHINE_ARCH} by
just checking ${MACHINE_PLATFORM}.
* Bug fixes
* New features:
- otherlibs/labltk: browser uses menu bars instead of menu buttons
Changes 3.09.0:
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.
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.
* Other (see 'Changes')
files are only built and installed if "opt" is passed as a build
target. This fixes installation on platforms on which the native-code
compiler is not supported, e.g. NetBSD/amd64.
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)
- camlp4: install argl.* files (PR#3439)
- ocamldoc: add -man-section option
- labltk: add the "solid" relief option (PR#3343)
- compiler: ocamlc -i now prints variance annotations
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)
- typing: erroneous partial match warning for polymorphic variants (PR#3424)
- runtime: handle the case of an empty command line (PR#3409, PR#3444)
- stdlib: make Sys.executable_name an absolute path in native code (PR#3303)
- runtime: fix memory leak in finalise.c
- runtime: auto-trigger compaction even if gc is called manually (PR#3392)
- stdlib: fix segfault in Obj.dup on zero-sized values (PR#3406)
- camlp4: correct parsing of the $ identifier (PR#3310, PR#3469)
- windows (MS tools): use link /lib instead of lib (PR#3333)
- windows (MS tools): change default install destination
- autoconf: better checking of SSE2 instructions (PR#3329, PR#3330)
- graphics: make close_graph close the X display as well as the window (PR#3312)
- num: fix big_int_of_string (empty string) (PR#3483)
- num: fix big bug on 64-bit architecture (PR#3299)
- str: better documentation of string_match and string_partial_match (PR#3395)
- unix: fix file descriptor leak in Unix.accept (PR#3423)
- unix: miscellaneous clean-ups
- unix: fix documentation of Unix.tm (PR#3341)
- graphics: fix problem when allocating lots of images under Windows (PR#3433)
- compiler: fix error message with -pack when .cmi is missing (PR#3028)
- cygwin: fix problem with compilation of camlheader (PR#3485)
- stdlib: Filename.basename doesn't return an empty string any more (PR#3451)
- stdlib: better documentation of Open_excl flag (PR#3450)
- ocamlcp: accept -thread option (PR#3511)
- ocamldep: handle spaces in file names (PR#3370)
- compiler: remove spurious warning in pattern-matching on variants (PR#3424)
- windows: better handling of InterpreterPath registry entry (PR#3334, PR#3432)
(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).

Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
- 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.
${CC} with options or '-libs' specification.
This fix the build of the package with threaded tcl/tk libraries
from the tcl/tk packages.
While here remove FIX_RPATH, bl3 framework takes care of that for us.
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.
* For consistency use SYS_bsd for system type
on powerpc. We differ from SYS_elf (presumably Linux) on
a few points here anyway.
* Fix signal handling on powerpc which caused a
seg fault when compiling native code version of coq.
* Install ocamllex.opt, camlp4o.opt and camlp4r.opt too.
Makefiles simply need to use this value often, for better or for
worse.
(2) Create a new variable FIX_RPATH that lists variables that should
be cleansed of -R or -rpath values if ${_USE_RPATH} is "no". By
default, FIX_RPATH contains LIBS, X11_LDFLAGS, and LDFLAGS, and
additional variables may be appended from package Makefiles.

Changes since 3.01:
Too much to list here - see http://caml.inria.fr/ocaml/Changes
Note that this release includes camlp4, thus rendering that package
redundant.
novelties compared with its ancestor, Caml Light, are:
* Full support for objects and classes -- here combined for the first time
with ML-style type reconstruction.
* A powerful module calculus in the style of Standard ML (but retaining
separate compilation).
* A high-performance native code compiler (in addition to a Caml
Light-style bytecode compiler).
TO BE DONE: install emacs mode, get native compiler working on ARCHs that
support it.
