configure script since pkgsrc will set MACHINE_GNU_PLATFORM to
sparc-sun-solaris2 on a solaris/sparc machine. This gets this package closer
to building on solaris with the sunpro compiler.

Changes since 6.7:
- Added some support for Dragonfly BSD. (Thanks to Joerg Sonnenberger and
Thomas Klausner.)
- Improvements to the HP/UX section of configure.in.
(Thanks to Andreas Tobler.)
- GC_unix_get_mem could neglect to release the malloc lock on Irix, under
extremely unlikely circumstances. Thanks to Jean-Baptiste Nivois for
some careful code reading.
- Added support for kFreeBSD + glibc (Thanks to Petr Salinger)
- Fix more MacOS threads memory leaks (Thanks to Allan Hsu)
- Added initial Solaris/X86-64 support (Thanks to Rainer Orth)
- Applied a long-lost MINGW patch from Gerard Allan for malloc redirection
with threads. This one probably makes no sense for 7.0, and was not applied
there.
- The Solaris/SPARC definition of GC_INIT() in gc.h wasn't C++-compilable.

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.

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).

Since 6.6:
- Add "int" to Solaris "end" and "etext" declaration in gc.h. Declared
the symbols with underscores and as arrays, since that's what's actually
used. Perhaps this could all just be removed? (Thanks to John Bowman.)
- Fixed ARM GC_test_and_set code. (Thanks to Kazu Hirata and Paul Brook.)
- Added casts for assignments to hb_last_reclaimed, which truncate the
value. Added a cast to GC_adj_words_allocd. Use GetModuleHandleA
when retrieving a handle to kernel32.dll under win32. (Thanks to the
Visual Prolog developers.)
- Added Tandem S-Series support. (Thanks to Craig McDaniel. A modified
version of his patch was applied, and hence breakage is probably not
his fault.)
- Remove spurious gc:: qualifier for operator delete[] in gc_cpp.h.
(Thanks to Hanno Boeck.)
- Changed a test for LINUX in config_macros.h to one for __linux__.
- Fix ppc 64 test_and_set code by removing it. (Thanks to Christian
Thalinger.)
- Add prototypes for GC_finalizer_notifier and GC_thr_init. (Thanks to
David Ayers.)
- Use ld instead of nonexistent ldz instruction in Darwin FindTopOfStack.
(Thanks to Andreas Tobler.)
- Add support for Darwin/X86. (Thanks to Geoff Norton and the Mono
developers.)
- Merge in some recent gcc fixes. Add ppc64 asm code. (Thanks to Bryce
McKinley and other gcj developers.)
- Scan MEM_PRIVATE sections under Windows ME and predecessors.
- Interior pointers with some largish offsets into large objects could
be ignored, if GC_all_interior_pointers was set. (Oddly this worked
correctly for stack references if it was not set. Otherwise it failed
for both stack and heap references.) Thanks to Andrew McKinlay for the
critical test case.
- Integrated Tatsuya Bizenn's NETBSD threads support, with some
minimally tested changes.
- Added GC_strdup and friends to make leak detection work correctly
for strdup clients. (Thanks to Jon Moore.) Fixed the existing strdup
with malloc redirection to handle a null malloc return correctly.
- Fix Makefile.am, so it handles exe extensions under Cygwin correctly
for gctest.

other changes are outlined in
http://mail-index.netbsd.org/tech-pkg/2005/12/02/0034.html
|

Since 6.5
- Fix CPU count detection for Irix and FreeBSD. (Thanks to Dan Bonachea.)
- Integrate Dan Bonachea's patch for the IBM XLC compiler on Darwin.
- Integrated Andreas Tobler's FreeBSD/PowerPC patch.
- Don't access the GC thread structure from the restart handler. It's
unsafe, since the handler may run too late. (Thanks to Ben Maurer for
tracking this down.)
- Applied Christian Thalinger's patch to change comment syntax in
alpha_mach_dep.S.
- Added test for GC_no_dls in GC_dyld_image_add for DARWIN. (Thanks to
Juan Jose Garcia Ripoli).
- Use LINUX_STACKBOTTOM for Linux/SH and LINUX/ARM. (Thanks to Sugioka
Toshinobu and Christian Thalinger.)
- Rewrote GC_parse_map_entry. This assumed a fixed column layout of
/proc/self/maps on Linux. This ceased to be true about 2 years ago.
The old code is probably quite problemetic with -DREDIRECT_MALLOC. It
is also used by default for IA64, though I haven't seen actual failures
there.
- More consistently define HBLKSIZE to 4096 on 64 bit architectures with
4K pages. (Thanks to Andrew Haley.)
- With win32 threads, GC_stop_world needs to acquire GC_write_cs. (Thanks
to Ben Hutchings for the observation and patch.)
- Move up struct callinfo declaration to make gcc 4.0.2. happy.

which can take multiple values -- "pax" or "gtar". The default value
of EXTRACT_USING is "pax", which more closely matches reality since
before, we were using bootstrap "tar" for ${GTAR} and it was actually
pax-as-tar. Also, stop pretending pax-as-tar from the bootstrap kit
or on NetBSD is GNU tar. Lastly, in bsd.pkg.extract.mk, note whether
we need "pax" or "gtar" depending on what we need to extract the
distfiles.

- Merge gcconfig.h changes from gcc tree.
- Unconditionally include gc_priv.h in solaris_pthreads.c, win32_threads.h,
aix_irix_threads.c, and solaris_threads.c to get thread definitions.
- Start marker threads in GC_thr_init, so that they get started even
if no other threads are ever started. (Oddly enough, the parallel
collector worked correctly, though not well, with no helper threads.)
- Go ahead and split large blocks in GC_allochblk_nth if GC_dont_gc
is set. (Thanks to Alexander Petrossian.)
- GC_PRINT_BACK_HEIGHT would deadlock with thread support.
- Let in_progress_space in backgraph.s grow dynamically.
- Fix README.solaris2. The GC_thr_init() hack doesn't work anymore.
- Convert GC_finalizer_mem_freed to bytes in allchblk.c.
- Add missing declaration for GC_generic_malloc_words_small_inner.
Without it, s390x breaks. (Thanks to Ulrich Weigand.)
- Applied several MacOSX patches to support older tool chains.
(Thanks to Stefan Ring.)
- Bug fix for NetBSD/amd64. (Thanks to Marc Recht.) Add NetBSD/sh3
support. (Thanks to Uchiyama Yasushi.)
- Fixed an uninitialized variable in cordprnt.c. (Thanks to gcc for
providing the warning.)
- Eliminated some, but not all, gcc -Wall warnings.
- Changed some old style casts to reinterpret_cast in new_gc_alloc.h.
(Thanks to Dan Grayson.)
- GC_extend_size_map shouldn't adjust for GC_all_interior_pointers if
GC_DONT_ADD_BYTE_AT_END is set.
- Changed some (long) casts to (word) in preparation for win64.
(Thanks to Peter Colson.)
- Changed "int stack_size" declaration in pthread_support.c to use
size_t. (Only mattered with GC_ASSERTIONS enabled.)
- Added CRIS (etrax) support. (Thanks to Simon Posnjak and
Hans-Peter Nilsson.)
- Removed GC_IGNORE_FB frame buffer recognition, and replaced
it with a check that the mapping type is MEM_IMAGE.
In theory, this should work much better, but it is a high
risk change for win32. (Thanks to Ashley Bone for the crucial
experimental data behind this, and to Rutger Ovidus for
some further experiments.)
- Fixed print_block_list to print the correct kind number for
STUBBORN. (Thanks to Rutger Ovidus.)
- GC_allochblk_nth incremented GC_words_wasted by bytes rather than
words.
- Consider GC_words_wasted in GC_adj_words_allocd only if it is within
reason. (A hack to avoid some extremely unlikely scenarios in which
we manage to allocate only "wasted" space. 7.0 has a better fix.)
- Changed PowerPC GC_clear implementation to use lwsync instead of
eieio, since the documentation recommends against eieio, and
it seems to be incorrect if the preceding memory op is a load.
- Fixed print_block_list to print the correct kind number for
STUBBORN. (Thanks to Rutger Ovidus.)
- GC_allochblk_nth incremented GC_words_wasted by bytes rather than
words.
- Have configure.in generate an error if it is asked to support
pthreads, but doesn't know how to.
- Added Kazuhiro Inaoka's patch for Renesas M32R support.
- Have the GNU build mechanism link with -ldl. Rename THREADLIBS
to THREADDLLIBS to reflect this. (Thanks to Sven Verdoolaege.)
- Added Hannes Mehnert's patch for FreeBSD/SPARC support.
- Merged some FreeBSD specific patches to threadlibs.c and dyn_load.c.
(Thanks tp John Merryweather Cooper.)
- Define MPROTECT_VDB on MACOSX only if threads are being used, since the
dirty page tracking mechanism uses threads. (This avoids an undefined
reference to _GC_darwin_register_mach_handler_thread.)
- By popular demand, use __libc symbols only if we are built with
USE_LIBC_PRIVATES, which is off by default, and not otherwise documented.
- Ignore GC_enable_incremental() requests when KEEP_BACK_PTRS is set.
The GC itself will dirty lots of pages in this cases, probably making
it counterproductive on all platforms. And the DARWIN port crashes.

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.
|
|
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".

changes:
- Add a patch provided by UCHIYAMA Yasushi in PR 26180 to support NetBSD/sh3.
- Correctly define ELFSIZE for NetBSD. Fixes PR 26252 by Kouichirou Hiratsuka.
Bump BUILDLINK_DEPNDS to 6.3nb1 for the ELFSIZE fix.

This is mostly a bug fix release.
Selection of changes:
- most pkgsrc patches have been integrated
- amd64 support for NetBSD/OpenBSD (thanks to drochner@)
- enhanced Darwin support

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.

Since 6.2alpha5:
- There was extra underscore in the name of GC_save_registers_in_stack
for NetBSD/SPARC. (Thanks to Jaap Boender for the patch.)
- Integrated Brian Alliet's patch for Darwin. This restructured the
linuxthreads/pthreads support to separate generic pthreads support
from more the system-dependent thread-stopping code. I believe this
should make it easier to eliminate the code duplication between
pthreads platforms in the future. The patch included some other
code cleanups.
- Integrated Dan Bonachea's patch to support AIX threads. This required
substantial manual integration, mostly due to conflicts with other
recent threads changes. It may take another iteration to
get it to work.
- Removed HPUX/PA-RISC support from aix_irix_threads.c. It wasn't used
anyway and it cluttered up the code. And anything we can do to migrate
towards generic pthreads support is a good thing.
- Added a more explicit test for tracing of function arguments to test.c.
(Thanks to Dan Grayson.)
- Added Akira Tagoh's PowerPC64 patch.
- Fixed some bit rot in the Cygwin port. (Thanks to Dan Bonachea for
pointing it out.) Gc.h now includes just windows.h, not winbase.h.
- Declared GC_save_regs_in_stack() in gc_priv.h. Remove other declarations.
- Changed --enable-cplusplus to use automake consitionals. The old way
confused libtool. "Make install" didn't work correctly for the old version.
Previously --enable-cplusplus was broken on cygwin.
- Changed the C version of GC_push_regs to fail at compile time if it is
generated with an empty body. This seems to have been the cause of one
or two subtle failures on unusual platforms. Those failures should
now occur at build time and be easily fixable.
Since 6.2alpha6:
- Integrated a second round of Irix/AIX patches from Dan Bonachea.
Renamed mips_sgi_mach_dep.S back to mips_sgi_mach_dep.s, since it requires
the Irix assembler to do the C preprocessing; gcc -E doesn't work.
- Fixed Makefile.direct for DARWIN. (Thanks to Manuel Serrano.)
- There was a race between GC_pthread_detach and thread exit that could
result in a thread structure being deallocated by GC_pthread_detach
eventhough it was still needed by the thread exit code. (Thanks to
Dick Porter for the small test case that allowed this to be debugged.)
- Fixed version parsing for non-alpha versions in acinclude.m4 and
version checking in version.h.
|
|
|
|
- GC_invoke_finalizers could, under rare conditions, set
GC_finalizer_mem_freed to an essentially random value. This could
possibly cause unbounded heap growth for long-running applications
under some conditions. (The bug was introduced in 6.1alpha5, and
is not in gcc3.3. Thanks to Ben Hutchings for finding it.)
- Attempted to sanitize the various DLL macros. GC_USE_DLL disappeared.
GC_DLL is used instead. All internal tests are now on GC_DLL.
README.macros is now more precise about the intended meaning.
- Include DllMain in the multithreaded win32 version only if the
collector is actually built as a dll. (Thanks to Mohan Embar for
a version of the patch.)
- Hide the cygwin threadAttach/Detach functions. They were violating our
namespace rules.
- Fixed an assertion in GC_check_heap_proc. Added GC_STATIC_ASSERT.
(Thanks again to Ben Hutchings.)
- Removed some obsolete definitions for Linux/PowerPC in gcconfig.h.
- CORD_cat was not rebalancing unbalanced trees in some cases, violating
a CORD invariant. Also tweaked the rebalancing rule for
CORD_cat_char_star. (Thanks to Alexandr Petrosian for the bug report
and patch.)
- Added hand-coded structured exception handling support to mark.c.
This should enable support of dynamic libraries under win32 with
gcc-compiled code. (Thanks to Ranjit Mathew for the patch.)
Turned on dynamic library scanning for win32/gcc.
- Removed some remnants of read wrapping. (Thanks to Kenneth Schalk.)
GC_USE_LD_WRAP ws probably broken in recent versions.
- The build could fail on some platforms since gcconfig.h could include
declarations mentioning ptr_t, which was not defined, e.g. when if_mach
was built. (Thanks to Yann Dirson for pointing this out.) Also
cleaned up tests for GC_PRIVATE_H in gcconfig.h a bit.
- The GC_LOOP_ON_ABORT environment variable interfered with incremental
collection, since the write fault handler was erroneously overridden.
Handlers are now set up in the correct order.
- It used to be possible to call GC_mark_thread_local_free_lists() while
the world was not stopped during an incremental GC. This was not safe.
Fortunately, it was also unnecessary. Added GC_world_stopped flag
to avoid it. (This caused occasional crashes in GC_set_fl_marks
with thread local allocation and incremental GC. This probably happened
primarily on old, slow multiprocessors.)
- Allowed overriding of MAX_THREADS in win32_threads.c from the build
command line. (Patch from Yannis Bres.)
- Taught the IA64/linux code to determine the register backing store base from
/proc/self/maps after checking the __libc symbol, but before guessing.
(__libc symbols are on the endangered list, and the guess is likely to not
always be right for 2.6 kernels.) Restructured the code to read and parse
/proc/self/maps so it only exists in one place (all platforms).
- The -DUSE_PROC_FOR_LIBRARIES code was broken on Linux. It claimed that it
also registered the main data segment, but didn't actually do so. (I don't
think anyone actually uses this configuration, but ...)
- Made another attempt to get --enablecplusplus to do the right thing.
Since there are unavoidable problems with C programs linking against a
dynamic library that includes C++ code, I separated out the c++ code into
libgccpp.

in include/ rather than include/gc/.
When boehm-gc 6.2 is out, this should be removed, fixing the package to
install things in both places as intended (removing patch-af), bumping
the version in this buildlink and bumping revisions for all packages
using this one.
As discussed with wiz@. Fixes pkg/21521 by charlie at rubberduck.com.
