o Remove patches which are no longer necessary, since they either
came from upstream or have been adopted there
o Update the PLIST to sync with what's being installed
Upstream changes:
- Functionality
+ The FileHandle PMC now exposes the exit code of child process
that was run as pipe.
+ Experimental support for overriding VTABLE invoke in PIR objects
was added.
+ The method 'type' was added to the PackfileAnnotations PMC.

+ The files installed by 'make install-dev' are now covered by
'make install' as well.
+ The experimental ops 'fetch' and 'vivify' were added.
+ The -I option to the command 'parrot' now prepends items to
the search path.
+ The Context struct was substituted with auto attributes
(context_auto_attrs branch).
+ Use the osname determined in auto::arch in subsequent configuration
steps (convert_OSNAME branch).
+ Eliminated dependence on Perl 5 '%Config' in auto::format
(auto_format_no_Config branch).
+ MultiSub PMCs now stringify to the name of their first candidate,
instead of the number of candidates.
+ The platform detection at the start of the configuration process
was improved.
+ The 'lineof' method on CodeString objects now precomputes line
number information to be more efficient on variable-width
encoded strings.

in ext/nqp-rx.
- New NQP available as nqp-rx.pbc or parrot-nqp fakecutable.

is now hosted on github and will be removed from the Parrot
core. (eligible in 2.1)
+ The 'Parrot_call_*' functions for invoking a sub/method object from C are
deprecated. They are replaced by 'Parrot_ext_call'. (eligible in 2.1)
+ All bitwise VTABLE functions are deprecated. (eligible in 2.1)
+ All bitwise ops will become dynops. (eligible in 2.1)
- Realized deprecations

+ The VTABLE function instantiate_str() was removed.
+ Building of parrot_nqp was removed.
- Tests
+ The test coverage of the time-related ops was much improved.
+ New testing functions in Test::More: lives_ok() and dies_ok().
+ The Perl 5 based test scripts t/op/bitwist.t, t/op/comp.t,
t/op/inf_nan.t, t/op/literal.t, t/op/number.t, t/op/sprintf2.t,
and t/op/00ff-dos.t were converted to PIR.
+ The test scripts t/op/annotate.t and t/op/time.t have begun
to be translated from Perl 5 to PIR.
+ In some tests the dependency on %Config from Perl 5 was eliminated.
- Documentation
+ The meaning of 'p' means in NCI function call signatures was clarified.

was correct, it was mis-placed in the file. It needs to include
<elf.h> or the moral equivalent of that before the symbols can be
tested. This now corresponds with what's committed upstream.
Again, since this is a build fix, no revision bump should be required.
|
|
instead of literal integers. Again, this should not result in different
code, so no reason to bump revision.
|
|
in no code change and adding portability to NetBSD 3.x, so no
revision bump:
o Let the workaround for missing R_PPC_ADDR16{HI,LO} work for other
systems who also define R_PPC_16_{HI,LO} instead.
o Add portability to NetBSD/powerpc 3.x, which has a very minimalist
<powerpc/elf_machdep.h> file.

|
fully built and installed when the build is run as root. The reason
this is problematical is that perldoc changes uid if run as root, to
either 'nobody', 'nouser' or uid -2, for security reasons, and then
cannot write files owned by root or create files in directories owned
by root with 'normal' permissions.
No revision bump as this should purely be a build fix.
|
|
Pkgsrc changes:
o New MASTER_SITES
o Take maintainership (apologies if I'm stepping on someone's toes)
o The package now has built-in knowledge if the CPU arch has working
jit support (currently i386, powerpc and arm, of which the two first
have been tested), so there's no need to direct the jit support from
the main Makefile
o Update PLIST
o Added patches to port to NetBSD/powerpc (reported upstream)
o Added patch to remove a GNUism from one of the shell scripts
(test using == in place of =)
Upstream changes:
o Too many to mention; there have been some 20-odd number of
intervening releases since the 0.4.11 release of 2007-Apr-17,
according to
http://docs.parrot.org/parrot/latest/html/docs/parrothist.pod.html
which contains the release history.

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.

patch with a more tolerant version of patch (like netbsd's) gives two
copies of the definitions in the same file, with who knows what
consequences. Applying the patch with a less tolerant version of patch
fails.
So, remove it, and bump PKGREVISION just in case.

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

|
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

that they look nicer.

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).

around at either build-time or at run-time is:
USE_TOOLS+= perl # build-time
USE_TOOLS+= perl:run # run-time
Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.

which may form part of Perl or Python's future, into the NetBSD packages
collection.
Provided in PR 13933 by Chris Pinnock <cjep@interoute.net.uk>, tarted
up somewhat by me.
PARROT: A bytecode language possible to be used in the future by
Perl 6 and a Python.
The idea was originally an April fool's joke...
"What we're releasing today is a very, very early alpha of the Parrot
interpreter. At the moment, we have support for some simple
operations on integer, floating point and string registers, and the
ability to read in and execute bytecode. We also have an assembler
which can generate bytecode output from Parrot assembly."
