|
|
* win32_threads.c (GC_register_my_thread_inner): Don't recognize

for WinCE).

Ivan's description of the patch follows. Note that a few pieces like
|
||
|
|
the GC_malloc(0) patch, were not applied since an alternate had been
|
||
|
|
previously applied. A few differed stylistically from the rest of
|
||
|
|
the code (mostly casts to void * instead of target type),
|
||
|
|
or were classified as too minor to bother. Note that
|
||
|
|
all of Ivan's static declarations which did not correct outright
|
||
|
|
naming bugs (as a few did), where replaced by STATIC, which is
|
||
|
|
ignored by default.
|
||
|
|
|
||
|
|
- minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for
|
||
|
|
GC_malloc(0));
|
||
|
|
- addition of missing getter/setter functions for public variables
|
||
|
|
(may be useful if compiled as Win32 DLL);
|
||
|
|
- addition of missing GC_API for some exported functions;
|
||
|
|
- addition of missing "static" declarator for internal functions
|
||
|
|
and variables (where possible);
|
||
|
|
- replacement of all remaining K&R-style definitions with ANSI
|
||
|
|
C ones (__STDC__ macro is not used anymore);
|
||
|
|
- addition of some Win32 macro definitions (that may be missing in
|
||
|
|
the standard headers supplied with a compiler) for GWW_VDB mode;
|
||
|
|
- elimination of most compiler warnings (except for
|
||
|
|
"uninitialized data" warning);
|
||
|
|
- several typos correction;
|
||
|
|
- missing parenthesis addition in macros in some header files of
|
||
|
|
"libatomic_ops" module.
|
||
|
|
|
||
|
|

* finalize.c (GC_unreachable_finalize_mark_proc): Don't return void
|
||
|
|
value.

|
|
||
|
|
== [7.0alpha9] 2007-05-15 ==

|
||
|
|
|
||
|

|
||

|
||
|
|
* README.changes: Point to ChangeLog.

|
|
|
||
|
|
* darwin_stop_world.c: Move THREAD_FLD defines to ...
|
||
|
|
* include/private/gc_priv.h: ... here.
|
||
|
|
Fix THREAD_STATE definitions for ppc64.
|
||
|
|
* os_dep.c (catch_exception_raise): Use THREAD_FLD for exc_state member
|
||
|
|
access.
|
||
|
|
|
||
|
|
* configure.ac (i586-darwin): Replaced HAS_I386_THREAD_STATE_* with
|
||
|
|
HAS_X86_THREAD_STATE32_*.
|
||
|
|
(x86_64-*-darwin*): Extended the above check for x86_64-*-darwin* with
|
||
|
|
HAS_X86_THREAD_STATE64_*.
|
||
|
|
Added value 1 in the above AC_DEFINE's. Important for the upcoming
|
||
|
|
Leopard.
|
||
|
|
* include/private/gcconfig.h: Modified X86_64 define for Darwin.
|
||
|
|
Removed __x86_64__ check in POWERPC section. Added base definitions
|
||
|
|
for the X86_64 Darwin port.
|
||
|
|
* include/private/gc_priv.h: Added GC_MACH_HEADER and GC_MACH_SECTION
|
||
|
|
to distinguish between 32 and 64-bit applications. Added definitions
|
||
|
|
for X86_64 Darwin.
|
||
|
|
* darwin_stop_world.c: Added HAS_X86_THREAD_STATE64___RAX. And
|
||
|
|
replaced HAS_I386_THREAD_STATE___EAX with HAS_X86_THREAD_STATE32___EAX.
|
||
|
|
(GC_push_all_stacks): Added code for X86_64 Darwin. Even for the
|
||
|
|
!DARWIN_DONT_PARSE_STACK. Maybe obsolete.
|
||
|
|
* dyn_load.c (GC_dyld_name_for_hdr): Use GC_MACH_HEADER.
|
||
|
|
(GC_dyld_image_add): Use GC_MACH_HEADER and GC_MACH_SECTION.
|
||
|
|
Distinguish between getsectbynamefromheader_64 and
|
||
|
|
getsectbynamefromheader.
|
||
|
|
* os_dep.c (catch_exception_raise): Introduce exception definition for
|
||
|
|
X86_64 Darwin. Replaced old i386_EXCEPTION_STATE_* definition with
|
||
|
|
x86_EXCEPTION_STATE32_*. Add X86_64 for exc_state.faultvaddr.

== [7.0alpha7] 2006-09-19 ==
|
||
|
|
|
||
|
|
* More 6.7 changes.
|
||
|
|
* Declare GC_dump() in gc.h.
|
||
|
|
* Add --enable-large-config, which just defines the LARGE_CONFIG macro.
|
||
|
|
* Make GlobalAlloc address alignment a bit more intuitive (thanks to
|
||
|
|
Charles Mills).
|
||
|
|
* Use #elif in the definitions of GET_MEM.
|
||
|
|
* Overhaul porting.html. Remove corresponding text from README.
|
||
|
|
* Fix typo in DARWIN section of gcconfig.h.
|
||
|
|
* Fix Darwin thread memory leak (thanks to Bruce Mitchener).
|
||
|
|
* Update x86 AO_test_and_set implementation to use "=q".
|
||
|
|
* Add $(EXEEXT) to many tests in tests/tests.am. (Corresponds to a
|
||
|
|
6.7 fix, which no longer applied.)
|
||
|
|
* Fix Darwin/PPC port.
|
||
|
|
* Fix Cygwin/threads port.
|
||
|
|
* Fix gcj malloc support.
|
||
|
|
* For GNU-style make, don't build libatomic_ops unless threads are requested.
|
||
|
|
This should allow single-threaded builds on platforms which do not
|
||
|
|
currently support libatomic_ops.
|
||
|
|
* Clean up and hopefully fix the CFLAGS calculation for GNU build.
|
||
|
|
(Substantially improves things on HP/UX.)
|
||
|
|
* Integrated Andrei Polushin's Visual C++ patches. These provide for
|
||
|
|
stack traces, better C++ debug support, and better log file handling.
|
||
|
|
Note that these change the location of the log file to a the path of the
|
||
|
|
executable with a .log extension. To get the old behavior back, define
|
||
|
|
OLD_WIN32_LOG_FILE. For the time being, I'm checking his project
|
||
|
|
files and the like into a windows-untested subdirectory. They
|
||
|
|
are almost certainly already out of date, but better than what we had
|
||
|
|
before.
|
||
|
|
* Fixed some win32 threads bugs, and added support for _beginthreadex.
|
||
|
|
* Fix zero size thread local allocation so that explicit deallocation
|
||
|
|
works correctly.
|
||
|
|
* Removed serious bug in GC_malloc_uncollectable(large size).
|
||
|
|
* Do not try to do thread-local gcj allocation in incremental mode. There
|
||
|
|
are races in setting up the descriptor.
|
||
|
|
* Add GC_INIT() to middle.c, fix some more GC_printfn calls.
|
||
|
|
* Some assertions erroneously used I_HOLD_LOCK() negatively, even though
|
||
|
|
it can now spuriously return TRUE.
|
||
|
|
* Rename SUNOS5 macro and OS name to SOLARIS and SUNOS5DL to SOLARISDL.
|
||
|
|
* On Linux and some Un*x variants, allocate memory by first trying sbrk,
|
||
|
|
and then switching to mmap if that fails.
|
||
|
|
* Fixed /proc/x/maps reading to deal with asynchronous deletions.
|
||
|
|
* Fix REDIRECT_MALLOC with threads on Linux. It now usually seems to work
|
||
|
|
with ugly hacks that include having calloc behave differently when it is
|
||
|
|
called from ld.so or the pthreads library. A reasonable amount of
|
||
|
|
infrastructure was added to support some of this. (Thanks to Roland McGrath
|
||
|
|
for ideas and information.)
|
||
|
|
* Import various updated build scripts.
|
||
|
|
* Add GC_register_has_static_roots_callback (thanks to Andrew Haley).
|
||
|
|
* Fix serious bugs in GC_malloc_atomic_uncollectable().
|
||
|
|
* Return GC_SUCCESS form GC_get_stack_base().
|
||
|
|
* Fix several atomic_ops problems on IA64 with HP Compiler.
|
||
|
|
* Update to atomic_ops-1.2.
|
||
|
|
* Fix hb_n_marks description and reclaim.c assertion.
|
||
|
|
* Various additional win32 threads fixes.
|
||
|
|
* Enable GC_ASSERTIONS for Debug build with NT_THREADS_MAKEFILE.
|
||
|
|
|
||
|
|
|
||
|
|
== [7.0alpha5] 2005-09-29 ==
|
||
|
|
|
||
|
|
* More 6.6, 6.7 changes.
|
||
|
|
* Some Solaris fixes, including some more general changes in how
|
||
|
|
the assembly pieces of mach_dep.c are handled.
|
||
|
|
* Removed a lot of SOLARIS_THREADS-specific code that was only
|
||
|
|
needed with the old implementation. This included many (mostly no-op)
|
||
|
|
versions of GC_is_fresh.
|
||
|
|
* Don't use atomic_ops in gc_locks.h unless we need threads.
|
||
|
|
* Fixed USE_MARK_BITS, which is once again the default without PARALLEL_MARK.
|
||
|
|
* Removed Solaris GC_INIT hack. It's a workaround for a long dead bug,
|
||
|
|
and it seemed to be wrong anyway.
|
||
|
|
* Changed win32_threads.c to require preprocessor-based interception
|
||
|
|
of thread routines by default. A client call to GC_use_DllMain is
|
||
|
|
now required to get the old behavior in which DllMain is used to implicitly
|
||
|
|
register threads. This was done for uniformity with other platforms, and
|
||
|
|
because the DllMain solution seemed to require very tricky code which,
|
||
|
|
at least in the past, imposed hard bounds on the number of threads.
|
||
|
|
* Many small changes to make thread support work again on Cygwin.
|
||
|
|
* Moved definition of allocator lock etc. to pthread_support.c and
|
||
|
|
win32_threads.c for those two cases.
|
||
|
|
* Got rid of the FASTLOCK() machinery. It doesn't seem useful on modern
|
||
|
|
platforms.
|
||
|
|
* Cleaned up the uncollectible allocation routines, speeding up the
|
||
|
|
slower paths. The code did enough unnecessary work off the critical path
|
||
|
|
that the underlying logic was getting hard to extract.
|
||
|
|
* No longer turn off THREAD_LOCAL_ALLOC with DBG_HDRS_ALL. Indications
|
||
|
|
are it just works, and I think the reasons for it not working disappeared
|
||
|
|
a while ago.
|
||
|
|
* Fixed bugs in hb_n_marks calculation and assertion.
|
||
|
|
* Don't use __builtin_expect for pre-3.0 gcc.
|
||
|
|
* Define GWW_VDB only for recent Microsoft tool chains.
|
||
|
|
* Add overview.html to doc directory.
|
||
|
|
* Fix NT_STATIC_THREADS_MAKEFILE, various compiler warnings.
|
||
|
|
* Made thread local allocation sort of work with Cygwin. The code should
|
||
|
|
be there to deal with other Windows variants, But non-Cygwin Windows
|
||
|
|
threads need more bug fixes.
|
||
|
|
|
||
|
|
|
||
|
|
== [7.0alpha4] 2005-08-02 ==
|
||
|
|
|
||
|
|
* Various 6.5, 6.6 changes.
|
||
|
|
* Removed GC_brief_async_signal_safe_sleep and used atomic_ops instead
|
||
|
|
(thanks to Ben Maurer).
|
||
|
|
* Integrated build patches from Davide Angelocola and Petter Urkedal.
|
||
|
|
* Fix dynamic-linker-based pthread call redirection.
|
||
|
|
* Renamed RS6000 to POWERPC/AIX.
|
||
|
|
* Allow recovery from SIGSEGV in marker on Linux. This works around
|
||
|
|
a race in thread stack marking if /proc is used to find roots. We do
|
||
|
|
that by default with malloc redirection and threads. This involved
|
||
|
|
moving some GC_find_limit and SETJMP related declarations to gc_priv.h.
|
||
|
|
* Added doc/porting.html file.
|
||
|
|
* Added ADD_HEAP_GUARD_PAGES for sbrk/*nix platforms to debug extreme
|
||
|
|
memory overwrite errors.
|
||
|
|
* Added trivial NO_INCREMENTAL flag to facilitate debugging.
|
||
|
|
* Added GC_getattr_np-based GC_get_stack_base (untested).
|
||
|
|
* Separated thread local allocation into a separate file and added the
|
||
|
|
beginning of win32 support for that.
|
||
|
|
|
||
|
|
|
||
|
|
== [7.0alpha3] 2005-04-28 ==
|
||
|
|
|
||
|
|
* Added support for dlopen-based interception of pthread functions.
|
||
|
|
This is only half done. The gc.h redefinitions currently interfere.
|
||
|
|
* Integrated major automake overhaul from Petter Urkedal.
|
||
|
|
|
||
|
|
|
||
|
|
== [7.0alpha2] 2005-04-07 ==
|
||
|
|
|
||
|
|
* GC_bytes_allocd was incremented by a possibly uninitialized variable
|
||
|
|
in GC_generic_malloc_inner. (Bug introduced in gc7.0alpha1. Thanks
|
||
|
|
to Ben Hutchings for tracking it down.)
|
||
|
|
* Win32 fixes (thanks to Ben Hutchings and Maurizio Vairani).
|
||
|
|
* Integrated Ben Hutchings' GetWriteWatch-based virtual dirty bit
|
||
|
|
implementation for win32.
|
||
|
|
* Removed pc_gc.tar and floppy targets in Makefile.direct. Removed
|
||
|
|
pc_excludes file.
|
||
|
|
* No longer include GC_bytes_wasted when evaluating allocation progress.
|
||
|
|
Since we are now counting live memory, it no longer makes sense.
|
||
|
|
* Applied Davide Angelocola's configure patch. There are now separate
|
||
|
|
Makefile.am's in the cord and tests subdirectory, more tests, etc.
|
||
|
|
* Renamed configure.in to configure.ac.
|
||
|
|
* Merged a very small number of Nathanael Nerode's configure.ac
|
||
|
|
cleanups from the gcc tree. Unfortunately, that file is a bit
|
||
|
|
different from ours.
|
||
|
|
* Changed EINTR handling in sem_wait slightly.
|
||
|
|
* Restructure the root marking code. Remove all traces of
|
||
|
|
USE_GENERIC_PUSH_REGS, and effectively make it the default.
|
||
|
|
Make it easier to pass a context pointer to the mark routine, in
|
||
|
|
case we ever want to do precise stack marking.
|
||
|
|
* Replace GC_start_blocking() and GC_end_blocking() with GC_do_blocking().
|
||
|
|
This remains undocumented, and only implemented for pthreads. But it
|
||
|
|
removes an otherwise unavoidable race with stores of callee-save
|
||
|
|
registers.
|
||
|
|
* Fix GC_n_mark_bits for the default MARK_BIT_PER_GRANULE case. This
|
||
|
|
resulted in bogus complaints in heap dumps.
|
||
|
|
* Upgrade to libatomic_ops-1.0, and update build structure to match.
|
||
|
|
* Remove SRC_M3 support. Clean up lock initialization code in misc.c.
|
||
|
|
* Removed gc_local_alloc.h. If THREAD_LOCAL_ALLOC is defined, the
|
||
|
|
thread local allocation routines are now called automatically.
|
||
|
|
* Renamed gc_inl.h back to gc_inline.h. Changed the interface appreciably
|
||
|
|
since locking has turned into a dominant issue, and in-line allocation
|
||
|
|
only makes sense if it's no worse than thread-local allocation.
|
||
|
|
Gc_inline.h is now also used to implement thread-local allocation.
|
||
|
|
* Finished replacing stubborn allocation with manual write barrier.
|
||
|
|
Untested.
|
||
|
|
* Use thread-local allocation code by default.
|
||
|
|
* Added GC_register_my_thread and friends for Posix and win32.
|
||
|
|
* Patch for GWW_VDB from Ben Hutchings.
|
||
|
|
* Removed explicit THREAD_LOCAL_ALLOC tests, since that now always
|
||
|
|
redefines GC_malloc.
|
||
|
|
* Removed now unused AIX memory allocation code.
|
||
|
|
* Various minor fixes for bugs introduced in 7.0alpha1.
|
||
|
|
|
||
|
|
|
||
|
|
== [7.0alpha1] 2004-11-09 ==
|
||
|
|
|
||
|
|
* Remove GC_PROTO, VOLATILE, GC_PTR, and GC_CONST. Assume ANSI C compiler
|
||
|
|
and use ANSI constructs unconditionally.
|
||
|
|
* Introduce #elif and #error in some of the appropriate places.
|
||
|
|
* Remove GC_printf cruft. Use stdargs.
|
||
|
|
* Remove separate Solaris threads support. Use the more generic Posix
|
||
|
|
implementation.
|
||
|
|
* Use atomic_ops for atomic operations and memory barriers.
|
||
|
|
* Clean up MPROTECT_VDB implementation. Use SA_SIGINFO wherever
|
||
|
|
possible.
|
||
|
|
* Remove broken SIGNALS stuff.
|
||
|
|
* Use size_t instead of word, where appropriate.
|
||
|
|
* Add .S.o rule to Makefile.am.
|
||
|
|
* Officially discontinue SunOS4, several old flavors of M68K (SunOS4,
|
||
|
|
A/UX, HP), IBM PC/RTs and RISCOS/Irix4. (I doubt the old code worked.
|
||
|
|
If anyone cares, these should be easy to resurrect.)
|
||
|
|
* Add EXPECT() in some critical places.
|
||
|
|
* Redefined hb_sz and hb_body to deal with bytes rather than words.
|
||
|
|
This affected a great deal of code. I would like to consistently use
|
||
|
|
byte offsets and sizes where there's not a convincing reason to do
|
||
|
|
otherwise.
|
||
|
|
* Redefined several other variables (GC_mem_found, GC_words_allocd)
|
||
|
|
etc. to use units of bytes. Most of these were also renamed to
|
||
|
|
reflect that fact.
|
||
|
|
* Killed as many "register" declarations as possible.
|
||
|
|
* Partially replaced stubborn allocation with manual write barrier.
|
||
|
|
It's currently broken.
|
||
|
|
* Restructured mark code, to allow mark bits to be kept either on
|
||
|
|
a per allocation granule or per object basis. The emphasis is
|
||
|
|
now on the -DUSE_MARK_BYTES option, since individual bits perform
|
||
|
|
quite badly on hyper-threaded P4s, and are probably suboptimal on
|
||
|
|
other architectures. -DUSE_MARK_BITS is currently broken, and may
|
||
|
|
be resurrected only for the single-threaded case. This significantly
|
||
|
|
reduced the cache footprint required by auxiliary GC data structures.
|
||
|
|
It also reduces space overhead for small heaps. It probably slows
|
||
|
|
things down slightly if interior pointers are very common.
|
||
|
|
* As part of the above, we now maintain an approximate count of set
|
||
|
|
mark bits in each heap block.
|
||
|
|
* As part of the above, the semantics of hb_map changed drastically.
|
||
|
|
For MARK_BIT_PER_OBJ, it doesn't exist. For MARK_BIT_PER_GRANULE,
|
||
|
|
it is purely a way to replace a mod instruction with a table lookup.
|
||
|
|
(Somewhat to my surprise, this still wins on modern hardware.)
|
||
|
|
* Removed PRINTSTATS, GATHERSTATS, and SILENT macros. Everything is
|
||
|
|
now controlled by GC_print_stats variable and GC_PRINT_STATS
|
||
|
|
and new GC_PRINT_VERBOSE_STATS environment variables.
|
||
|
|
* Add GC_log_printf and use it consistently for logging output.
|
||
|
|
* Unconditionally count the objects we reclaim in the sweep phase.
|
||
|
|
For thread local allocation, we need that anyway, and we expect
|
||
|
|
that's increasingly the only case that matters. And it simplifies
|
||
|
|
the code. In general expect minor performance hacks that benefit
|
||
|
|
only the single-threaded case to disappear.
|
||
|
|
* Remove GC_quiet from gc.h and elsewhere.
|
||
|
|
* Changed the heap expansion heuristic, and the definition of
|
||
|
|
GC_free_space_divisor, to refer to live data size, instead of total
|
||
|
|
heap size. I believe this is much more robust. It wasn't previously
|
||
|
|
possible, because we didn't have access to live data size.
|
||
|
|
* Thread local allocation added the extra byte in twice: Once in
|
||
|
|
thread_local_alloc, and once in malloc_many.
|
||
|
|
* Removed GC_malloc_words_small and GC_gcj_fast_malloc. A new
|
||
|
|
mechanism based on the thread local allocation data structures
|
||
|
|
is expected to be added instead. This should allow inlined code
|
||
|
|
that is both fast and doesn't rely on collector internals.
|
||
|
|
* Changed both free lists and reclaim lists to be indexed by granules
|
||
|
|
instead of words, norming halving their size.
|
||
|
|
* MERGE_SIZE is now the only option, and the macro was removed.
|
||
|
|
(Without it, we need a memory reference to GC_all_interior_pointers
|
||
|
|
anyway. Thus it costs us nothing.)
|
||
|
|
* Change GC_size_map to map to granules instead of words. Make sure
|
||
|
|
that every possible size up to TINY_FREELISTS is present.
|
||
|
|
* Split of macros need for fast inline allocation into gc_tiny_fl.h
|
||
|
|
in anticipation of a new inline allocator that doesn't rely on GC
|
||
|
|
internals.
|
||
|
|
* Changed thread local allocation to use GRANULE_BYTES and TINY_FREELISTS
|
||
|
|
in anticipation of a merge with the inline allocation code.
|
||
|
|
* Removed ALIGN_DOUBLE. This is mostly handled by GRANULE_BYTES.
|
||
|
|
* Make locking on most platforms conditional on GC_need_to_lock.

|
== [6.8] 2006-07-08 ==
|
||
|
|
|
||
|
|
* Added some support for Dragonfly BSD (thanks to Joerg Sonnenberger and
|
||
|
|
Thomas Klausner).
|
||
|
|
* Improvements to the HP/UX section of configure.in/configure.ac (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 inspection.)
|
||
|
|
* 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).

|
|
|
||
|
|
== [6.7] 2006-03-03 ==
|
||
|
|
|
||
|
|
* 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.
|
||
|
|
* 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__.
|
||
|
|
* 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 McKinlay 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
|
||
|
|
untested 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.

|
|
== [6.6] 2005-09-09 ==
|
||
|
|
|
||
|
|
* 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-Ripoll).
|
||
|
|
* 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 problematic 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.
|
||
|

|
|
|
||
|
|
== [6.5] 2005-05-22 ==
|
||
|
|
|
||
|
|
* Integrated Paolo Molaro's patch to deal with EINTR in sem_wait.
|
||
|
|
* Make GC_approx_sp() write to dummy location to ensure that stack
|
||
|
|
is grown here, when sp looks reasonable, rather than later, when
|
||
|
|
it might look like a bad memory reference. (Problem was never
|
||
|
|
observed that I know of. But on rereading the code it seemed
|
||
|
|
dubious.)
|
||
|
|
* Separate out GC_with_callee_saves_pushed and sometimes call
|
||
|
|
it from GC_suspend_handler in pthread_stop_world.c. Callee-save
|
||
|
|
register values sometimes failed to get traced under HP/UX on
|
||
|
|
PA-RISC. Linux/IA64 had the same problem, though non-stacked
|
||
|
|
callee-save registers seem to be so rarely used there that nobody
|
||
|
|
ever noticed.
|
||
|
|
* Integrated an ancient Darwin powerpc_darwin_machine_dep.s patch
|
||
|
|
from Andreas Tobler, which I had lost.
|
||
|
|
* Fix compare_and_exchange implementation for gcc/IA64 to deal with
|
||
|
|
pickier compiler versions.
|
||
|
|
* Fixed Itanium 32-bit ABI support (HP/UX). In particular, the
|
||
|
|
compare_and_exchange implementation didn't consider that possibility.
|
||
|
|
* Undefine GC_pthread_detach in win32_threads.c (thanks to
|
||
|
|
Tommaso Tagliapietra).
|
||
|
|
* Fixed inclusion of frame.h for NETBSD in os_dep.c.
|
||
|
|
* Applied Dan Bonachea's patch to use mmap on AIX.
|
||
|
|
* Several fixes to resurrect the Irix port on recent OS versions.
|
||
|
|
* Change ALPHA to use LINUX_STACKBOTTOM.
|
||
|
|
* Change SPARC64/LINUX to also use LINUX_STACKBOTTOM. Deal with potential
|
||
|
|
bad values of __libc_stack_end on that platform (thanks to David Miller).
|
||
|
|
* Relax gctest to allow larger heap if ALIGN_DOUBLE isn't set.
|
||
|
|
(Unnecessary in 7.0)
|
||
|
|
* Force a define of __STDC__=0 for the IBM compiler on AIX, so that
|
||
|
|
we get prototypes. (Unnecessary in 7.0)
|
||
|
|
* GC_INIT definition for AIX and CYGWIN referred to DATASTART and DATAEND
|
||
|
|
which are only defined in private include files.
|
||
|
|
* Integrated some small gcconfig.h patches from Dan Bonachea. Also
|
||
|
|
relaxed assertion about FreeBSD stack size in pthread_support.c.
|
||
|
|
* Integrated Andrew Begel's darwin_stop_world.c patch for 64-bit
|
||
|
|
support. This may need additional work.
|
||
|
|
* Avoided potentially infinite recursion in GC_save_callers if
|
||
|
|
the system backtrace calls malloc. The workaround currently requires
|
||
|
|
__thread support if this code is used with threads.
|
||
|
|
* Avoided another similar infinite recursion by conditionally
|
||
|
|
invoking GC_save_callers in alloc.c (thanks to Matthias Andree
|
||
|
|
for helping to track down both of these).
|
||
|
|
* Removed all traces of aix_irix_threads.c. AIX and Irix now use
|
||
|
|
pthread_support.c and pthread_stop_world.c. The old code appeared
|
||
|
|
to be unreliable for AIX, and was not regularly maintained.
|
||
|
|
* On Irix, ignore segments with MA_FETCHOP or MA_NOTCACHED attributed;
|
||
|
|
they're not always safe to read.
|
||
|
|
* Fixed a previously vacuous assertion (diagnosed by the SGI compiler)
|
||
|
|
in GC_remove_from_fl.
|
||
|
|
* Fix stack_size assertion in GC_pthread_create.
|
||
|
|
* Fix assertion in GC_steal_mark_stack.
|
||
|

|
|
|

|
|
== [6.4] 2004-12-21 ==
|
||
|
|
|
||
|
|
* 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.
|
||
|
|
* 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 Ovidius for
|
||
|
|
some further experiments.)
|
||
|
|
* 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 Ovidius).
|
||
|
|
* 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 to 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.

== [6.3] 2004-07-08 ==
|
||
|
|
|
||
|
|
* Compile test_cpp.cc with CXXCOMPILE instead of COMPILE.
|
||
|
|
* Very large allocations could cause a collector hang. Correct
|
||
|
|
calculation of GC_collect_at_heapsize.
|
||
|
|
* GC_print_hblkfreelist printed some bogus results if USE_MUNMAP
|
||
|
|
was defined.
|
||
|
|
* Include gc_config_macros.h in threadlibs.c.
|
||
|
|
* Correct MacOSX thread stop code (thanks to Dick Porter).
|
||
|
|
* SMALL_OBJ definition was off by one. This could cause crashes
|
||
|
|
at startup. (Thanks to Zoltan Varga for narrowing this down to
|
||
|
|
a trivial test case.)
|
||
|
|
* Integrate Paolo Molaro's patch to deal with a race in the Darwin
|
||
|
|
thread stopping code.
|
||
|
|
* Changed X86_64 implementation to use SA_SIGINFO in the MPROTECT_VDB
|
||
|
|
implementation. The old approach appears to have been broken by
|
||
|
|
recent kernels.
|
||
|
|
* Added GC_ATTR_UNUSED to eliminate a warning in gc_allocator.h (thanks
|
||
|
|
to Andrew Begel).
|
||
|
|
* Fix GC_task_self declaration in os_dep.c (thanks to Andrew Pinski).
|

* Fixed the X86_64 PREFETCH macros to correctly handle ia32e (which uses
|
||
|
|
different prefetch instructions from AMD64). (Thanks to H.J. Lu.)
|
||
|
|
* GC_config_macros.h did not correctly define GC_WIN32_THREADS from
|
||
|
|
GC_THREADS.
|
||
|
|
* Added simple_example.html.
|
||
|
|
* Merged Andrew Gray's patch to correctly restore signal handlers on
|
||
|
|
FreeBSD.
|
||
|
|
* Merged a patch from Andreas Jaeger to deal with prefetch-related warnings
|
||
|
|
on x86-64. Added some other casts so that the PREFETCH macros
|
||
|
|
always get a ptr_t argument. Removed some casts in the PREFETCH
|
||
|
|
implementations.
|
||
|
|
* Added a header guard for gc_allocator.h and changed GC_debug_free to
|
||
|
|
clobber contents of deallocated object (suggested by Jesse Jones).
|
||
|
|
* The signal masking code in pthread_stop_world.c contained some errors.
|
||
|
|
In particular SIGSEGV was masked in the handler, in spite of the fact that
|
||
|
|
it wrote to the heap. This could lead to an uncaught SIGSEGV, which
|
||
|
|
apparently became much more likely in Linux 2.6. Also fixed some
|
||
|
|
typos, and reduced code duplication in the same area.
|
||
|
|
* Remove ltconfig, clean up configure messages for DG/UX (thanks to
|
||
|
|
Adrian Bunk for the patches).
|
||
|
|
* Integrated NetBSD/OpenBSD patches from Marc Recht and Matthias Drochner.
|
||

|
|
== [6.3alpha5] 2004-03-30 ==
|
||
|
|
|
||
|
|
* Fix & vs && typo in GC_generic_malloc and
|
||
|
|
GC_generic_malloc_ignore_off_page. (Propagated from the gcc tree.)
|
||
|
|
* Removed SA_NODEFER hack from NetBSD and Solaris write-protect handler.
|
||
|
|
(According to Christian Limpach, the NetBSD problem is fixed.
|
||
|
|
Presumably so is the Solaris 2.3 problem.)
|
||
|
|
* Removed placement delete from gc_cpp.h for the SGI compiler (thanks
|
||
|
|
to Simon Gornall for the patch).
|
||
|
|
* Changed semantics of the GC_IGNORE_FB environment variable, based
|
||
|
|
on experimentation by Nicolas Cannasse pointing out that the old
|
||
|
|
interpretation was useless. We still need help in identifying win32
|
||
|
|
graphics memory mappings. The current "solution" is a hack.
|
||
|
|
* Removed "MAKEOVERRIDES =" from Makefile.am and thus Makefile.in.
|
||
|
|
It probably made more sense in the gcc context.
|
||
|
|
* Explicitly ensure that NEED_FIND_LIMIT is defined for {Open,Net}BSD/ELF.
|
||
|
|
* Replaced USE_HPUX_TLS macro by USE_COMPILER_TLS, since gcc often
|
||
|
|
supports the same extension on various platforms.
|
||
|
|
* Added some basic (completely untested) defines for win64, in support
|
||
|
|
of future work.
|
||
|
|
* Declared GC_jmp_buf in os_dep.s as JMP_BUF instead of jmp_buf, fixing
|
||
|
|
a memory overwrite bug on Solaris and perhaps other platforms.
|
||
|
|
* Added 0 != __libc_stack_end test to GC_linux_stack_base (thanks to
|
||
|
|
Jakub Jelinek for the patch and explaining the problem).
|
||
|
|
Otherwise pre-linking could cause the collector to fail.
|
||
|
|
* Changed default thread local storage implementation to USE_PTHREAD_SPECIFIC
|
||
|
|
for HP/UX with gcc. The compiler-based implementation appears to work
|
||
|
|
only with the vendor compiler.
|
||
|
|
* Export GC_debug_header_size and GC_USR_PTR_FROM_BASE from gc_mark.h,
|
||
|
|
making client mark code cleaner and less dependent on GC version.
|
||
|
|
* Export several new procedures and GC_generic_malloc from gc_mark.h
|
||
|
|
to support user-defined kinds. Use the new procedures to replace existing
|
||
|
|
code in gcj_mlc.c and typd_mlc.c.
|
||
|
|
* Added support for GC_BACKTRACES.
|
||
|
|
* Fixed a remaining problem in CORD_str with signed characters (thanks
|
||
|
|
to Alexandr Petrosian for the patch).
|
||
|
|
* Removed supposedly redundant, but very buggy, definitions of finalizer
|
||
|
|
macros from javaxfc.h. Fortunately this file probably has no users.
|
||
|
|
The correct declarations were already in gc.h.
|
||
|
|
* Also need to set GC_in_thread_creation while waiting for GC during
|
||
|
|
thread termination, since it is also possible to collect from an
|
||
|
|
unregistered thread in that case.
|
||
|
|
* Define NO_GETENV for Windows CE, since getenv doesn't appear to exist.
|
||
|
|
Plus some other minor WinCE fixes (thanks to Alain Novak).
|
||
|
|
* Added GC_register_describe_type_fn.
|
||
|
|
* Arrange for debugging finalizer registration to ignore non-heap
|
||
|
|
registrations, since the regular version of the routine also behaves
|
||
|
|
that way.
|
||
|
|
* GC_gcj_malloc and friends need to check for finalizers waiting to be run.
|
||
|
|
One of the more obscure allocation routines with missing a LOCK() call.
|
||
|
|
* Fixed cvtres invocations in NT_MAKEFILE and NT_STATIC_THREADS_MAKEFILE
|
||
|
|
to work with VS.NET.
|
||
|
|
* Cleaned up GC_INIT calls in test. Updated gc.man to encourage GC_INIT
|
||
|
|
use in portable code.
|
||
|
|
* Taught the GC to use libunwind if --enable-full-debug is specified on
|
||
|
|
IA64 and libunwind is present.
|
||
|
|
* The USE_MUNMAP code could get confused about the age of a block and
|
||
|
|
prematurely unmap it. GC_unmap_old had a bug related to wrapping of
|
||
|
|
GC_gc_no. GC_freehblk and GC_merge_unmapped didn't maintain
|
||
|
|
hb_last_reclaimed reasonably when blocks were merged. The code was
|
||
|
|
fixed to reflect original intent, but that may not always be an
|
||
|
|
improvement.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.3alpha4] 2004-01-01 ==
|
||
|
|
|
||
|
|
* USE_MMAP was broken by confusion in the code dealing with USE_MMAP_ANON.
|
||
|
|
* Darwin support was broken in alpha3 as a result of my mis-integration of
|
||
|
|
Andrew Begel's patches. Fixed with another patch from Andrew Begel.
|
||
|
|
* A new sanity check in pthread_stop_world.c:GC_push_all_stacks() was
|
||
|
|
overly aggressive. We may collect from an unregistered thread during
|
||
|
|
thread creation. Fixed by explicitly checking for that case. (Added
|
||
|
|
GC_in_thread_creation.)
|
||
|
|
|
||
|
|
|
||
|
|
== [6.3alpha3] 2003-12-20 ==
|
||
|
|
|
||
|
|
* Removed -DSMALL_CONFIG from BCC_MAKEFILE.
|
||
|
|
* Changed macros to test for an ARM processor (Patch from Richard Earnshaw.)
|
||
|
|
* Mostly applied a DJGPP patch from Doug Kaufman. Especially Makefile.dj
|
||
|
|
had suffered from serious bit rot.
|
||
|
|
* Rewrote GC_apply_to_maps, eliminating an off-by-one subscript error,
|
||
|
|
and a call to alloca (for lcc compatibility).
|
||
|
|
* Changed USE_MUNMAP behavior on POSIX platforms to immediately remap
|
||
|
|
the memory with PROT_NONE instead of unmapping it. The latter risks
|
||
|
|
an intervening mmap grabbing the address space out from underneath us.
|
||
|
|
Updated this code to reflect a cleaner patch from Ulrich Drepper.
|
||
|
|
* Replaced _T with _Tp in new_gc_alloc.h to avoid a MACOS X conflict.
|
||
|
|
(Patch from Andrew Begel.)
|
||
|
|
* Dynamically choose whether or not lock should spin on win32 (thanks
|
||
|
|
to Maurizio Vairani for the patch). This may be a significant performance
|
||
|
|
improvement for win32.
|
||
|
|
* Fix Makefile.direct to actually include NT_STATIC_THREADS_MAKEFILE
|
||
|
|
in the distribution (thanks to Maurizio Vairani).
|
||
|
|
* Maybe_install_looping_handler() was accidentally exported, violating
|
||
|
|
our name space convention.
|
||
|
|
* Made os_dep.c use sigsetjmp and SA_NODEFER for NetBSD. (Thanks to
|
||
|
|
Christian Limpach. I generalized the patch to use sigsetjmp on all
|
||
|
|
UNIX_LIKE platforms, admittedly a slightly risky move. But it may avoid
|
||
|
|
similar problems on some other platforms. I also cleaned up the definition
|
||
|
|
of UNIX_LIKE a bit.)
|
||
|
|
* Integrated Andrew Begel's Darwin threads patch, adjusted according to
|
||
|
|
some of Fergus Hendersons's comments. (Patch didn't apply cleanly,
|
||
|
|
errors are possible.)
|
||
|
|
* Added another test or two for the Intel 8.0 compiler to avoid
|
||
|
|
confusing it with gcc. The single-threaded collector should now build
|
||
|
|
with icc, at least on ia64.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.3alpha2] 2003-11-04 ==
|
||
|
|
|
||
|
|
* Re-enabled I_HOLD_LOCK assertion in aix_irix_threads.h.
|
||
|
|
* Put back the WINABI qualifier for GC_CreateThread. (Thanks to
|
||
|
|
Danny Smith for the patch. 6.3alpha1 had the qualifier in one place
|
||
|
|
but not elsewhere, which was clearly wrong.)
|
||
|
|
* Sometimes explicitly define __private_extern__ before DARWIN dyld.h
|
||
|
|
include. (Thanks to Andreas Tobler for posting the patch.)
|
||
|
|
* Included signal.h from pthread_support.c. Removed GC_looping_handler,
|
||
|
|
which was dead code.
|
||
|
|
* GC_find_start was misdeclared by gc_pmark.h if PRINT_BLACK_LIST was
|
||
|
|
defined (thanks to Glauco Masotti for testing and reporting this).
|
||
|
|
Changed GC_find_start to never just return 0. According to its
|
||
|
|
comment it doesn't, and it's unclear that's correct.
|
||
|
|
* GC_alloc_large had several largely compensating bugs in the
|
||
|
|
computation of GC_words_wasted. (It was confused about bytes vs.
|
||
|
|
words in two places.)
|
||
|
|
* Integrated Slava Sysoltsev's patch to support more recent versions of
|
||
|
|
the Intel compiler on IA64/Linux.
|
||
|
|
* Changed win32 spinlock initialization to conditionally set a spin count.
|
||
|
|
(Emmanual Stumpf pointed out that enabling this makes a large performance
|
||
|
|
difference on win32 multiprocessors.) Also cleaned up the win32 spinlock
|
||
|
|
initialization code a bit.
|
||
|
|
* Fixed thread support for HP/UX/IA64. The register backing store base for
|
||
|
|
the main thread was sometimes not set correctly. (Thanks to
|
||
|
|
Laurent Morichetti.)
|
||
|
|
* Added -DEMPTY_GETENV_RESULTS flag to work around Wine problem.
|
||
|
|
* Declare GC_stack_alloc and GC_stack_free in solaris_threads.h to
|
||
|
|
avoid 64-bit size mismatches (thanks to Bernie Solomon).
|
||
|
|
* Fixed GC_generic_push_regs to avoid a potential and very unfortunate
|
||
|
|
tail call optimization. This could lead to prematurely reclaimed
|
||
|
|
objects on configurations that used the generic routine and the new
|
||
|
|
build infrastructure (which potentially optimizes mach_dep.c).
|
||
|
|
This was a serious bug, but it's unclear whether it has resulted in
|
||
|
|
any real failures.
|
||
|
|
* Fixed CORD_str to deal with signed characters (thanks to Alexandr Petrosian
|
||
|
|
for noticing the problem and supplying the patch).
|
||
|
|
* Merged a couple of NOSYS/ECOS tests into os_dep.c from gcj (thanks
|
||
|
|
to Anthony Green).
|
||
|
|
* Partially merged a win32 patch from Ben Hutchings, and substantially
|
||
|
|
revised other parts of win32_threads.c. It had several problems.
|
||
|
|
Under MinGW with a statically linked library, the main thread was
|
||
|
|
not registered. Cygwin detached threads leaked thread descriptors.
|
||
|
|
There were several race conditions. For now, unfortunately the
|
||
|
|
static threads limit remains, though we increased it, and made table
|
||
|
|
traversal cost depend on the actual thread count.
|
||
|
|
There is also still some code duplication with pthread_support.c.
|
||
|
|
(Thread descriptors did become much smaller, since Ben Hutchings
|
||
|
|
removed the thread context from them.)
|
||
|
|
* Integrated a Solaris configure.in patch from Rainer Orth.
|
||
|
|
* Added GC_IGNORE_FB and associated warning to very partially address
|
||
|
|
the issue of the collector treating a mapped frame buffer as part
|
||
|
|
of the root set. (Thanks to David Peroutka for providing some
|
||
|
|
insight. More would be helpful. Is there anything that can be used
|
||
|
|
to at least partially identify such memory segments?)
|
||
|
|
|
||
|
|
|
||
|
|
== [6.3alpha1] 2003-07-26 ==
|
||
|
|
|
||
|
|
* Integrated some NetBSD patches by Marc Recht. These
|
||
|
|
were already in the NetBSD package.
|
||
|
|
* GC_pthread_create waited for the semaphore even if pthread_create failed.
|
||
|
|
(Thanks to Dick Porter for the pthread_support.c patch.) Applied the
|
||
|
|
analogous fix for aix_irix_threads.c.
|
||
|
|
* Added Rainer Orth's Tru64 fixes.
|
||
|
|
* The check for exceeding the thread table size in win32 threadDetach
|
||
|
|
was incorrect (thanks to Alexandr Petrosian for the patch).
|
||
|
|
* Applied Andrew Begel's patch to correct some reentrancy issues
|
||
|
|
with dynamic loading on Darwin.
|
||
|
|
* GC_CreateThread() was neglecting to duplicate the thread handle in
|
||
|
|
the table (thanks to Tum Nguyen for the patch).
|
||
|
|
* Pass +ESdbgasm only on PA-RISC machines with vendor compiler (thanks to
|
||
|
|
Roger Sayle for the patch).
|
||
|
|
* Applied more AIX threads patches from Scott Ananian.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.2] 2003-06-21 ==
|
||
|
|
|
||
|
|
* 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
|
||
|
|
even though 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.
|
||
|
|
* Issues identified (not yet fixed):
|
||
|
|
- A dynamic libgc.so references dlopen unconditionally, but doesn't link
|
||
|
|
against libdl.
|
||
|
|
- GC_proc_fd for Solaris is not correctly updated in response to a
|
||
|
|
fork() call. Thus incremental collection in the child won't work
|
||
|
|
correctly. (Thanks to Ben Cottrell for pointing this out.)
|
||
|
|
- --enable-redirect-malloc is mostly untested and known not to work
|
||
|
|
on some platforms.
|
||
|
|
- There seem to be outstanding issues on Solaris/X86, possibly with
|
||
|
|
finding the data segment starting address.
|
||
|
|
- Very large root set sizes (> 16 MB or so) could cause the collector
|
||
|
|
to abort with an unexpected mark stack overflow. (Thanks to
|
||
|
|
Peter Chubb.) NOT YET FIXED. Workaround is to increase the initial
|
||
|
|
size.
|
||
|
|
- The SGI version of the collector marks from mmapped pages, even
|
||
|
|
if they are not part of dynamic library static data areas. This
|
||
|
|
causes performance problems with some SGI libraries that use mmap
|
||
|
|
as a bitmap allocator. NOT YET FIXED. It may be possible to turn
|
||
|
|
off DYNAMIC_LOADING in the collector as a workaround. It may also
|
||
|
|
be possible to conditionally intercept mmap and use GC_exclude_static_roots.
|
||
|
|
The real fix is to walk rld data structures, which looks possible.
|
||
|
|
- Incremental collector should handle large objects better. Currently,
|
||
|
|
it looks like the whole object is treated as dirty if any part of it is.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.2alpha6] 2003-06-05 ==
|
||
|
|
|
||
|
|
* There was an 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.
|
||
|
|
* 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 consistently. 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.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.2alpha5] 2003-05-14 ==
|
||
|
|
|
||
|
|
* 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.)
|
||
|
|
* 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 multi-threaded 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 re-balancing 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 was 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 (thanks to Yannis Bres for the patch).
|
||
|
|
* 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.

== [6.2alpha4] 2003-03-10 ==
|
||
|
|
|
||
|
|
* Use LINUX_STACKBOTTOM for >= glibc2.2 on Linux/MIPS. (See Debian bug
|
||
|
|
# 177204)
|
||
|
|
* Integrated Jeff Sturm and Jesse Rosenstock's MACOSX threads patches.
|
||
|
|
* Integrated Grzegorz Jakacki's substantial GNU build patch. "Make dist"
|
||
|
|
should now work for the GNU build process. Documentation files
|
||
|
|
are installed under share/gc.
|
||
|
|
* Tweaked gc_cpp.h to again support the Borland compiler (thanks to
|
||
|
|
Rene Girard for pointing out the problems).
|
||
|
|
* Updated BCC_MAKEFILE (thanks to Rene Girard).
|
||
|
|
* Added GC_ASSERT check for minimum thread stack size.
|
||
|
|
* Added --enable-gc-assertions.
|
||
|
|
* Added some web documentation to the distribution. Updated it in the
|
||
|
|
process.
|
||
|
|
* Separate gc_conf_macros.h from gc.h.
|
||
|
|
* Added generic GC_THREADS client-defined macro to set the appropriate
|
||
|
|
GC_XXX_THREADS internal macro. (gc_config_macros.h.)
|
||
|
|
* Add debugging versions of _ignore_off_page allocation primitves.
|
||
|
|
* Moved declarations of GC_make_closure and GC_debug_invoke_finalizer
|
||
|
|
from gc.h to gc_priv.h.
|
||
|
|
* Reset GC_fail_count even if only a small allocation succeeds.
|
||
|
|
* Integrated Brian Alliet's patch for dynamic library support on Darwin.
|
||
|
|
* gc_cpp.h's gc_cleanup destructor called GC_REGISTER_FINALIZER_IGNORE_SELF
|
||
|
|
when it should have called the lower case version, since it was
|
||
|
|
explicitly computing a base pointer.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.2alpha3] 2003-01-30 ==
|
||
|
|
|
||
|
|
* Don't include execinfo.h in os_dep.c when it's not needed, and may not
|
||
|
|
exist.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.2alpha2] ==
|
||
|
|
|
||
|
|
* Fixed the completely broken FreeBSD code in 6.2alpha1 (thanks to
|
||
|
|
Hironori Sakamoto for the patch).
|
||
|
|
* Changed IRIX reference in dbg_mlc.c to IRIX5 (thanks to Marcus Herbert).
|
||
|
|
* Attempted to work around the problems with .S filenames and the SGI
|
||
|
|
compiler. (Untested.)
|
||
|
|
* Worked around an HP/UX make issue with the GNU-style build process.
|
||
|
|
* Fixed the --enable-cplusplus build machinery to allow builds without
|
||
|
|
a C++ compiler. (That was always the intent ...)
|
||
|
|
* Changed the debugging allocation macros to explicitly pass the return
|
||
|
|
address for Linux and XXXBSD on hardware for which we can't get stack
|
||
|
|
traces. Use __builtin_return_address(0) to generate it when possible.
|
||
|
|
Some of the configuration work was cleaned up (good) and moved to gc.h
|
||
|
|
(bad, but necessary). This should make leak detection more useful
|
||
|
|
on a number of platforms. (Thanks to Fabian Thylman for the suggestion.)
|
||
|
|
* Fixed compilation problems in dbg_mlc.c with GC_ADD_CALLER.
|
||
|
|
* Bumped revision number for dynamic library.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.2alpha1] 2003-01-23 ==
|
||
|
|
|
||
|
|
* Guard the test for GC_DUMP_REGULARLY in misc.c with
|
||
|
|
"#ifndef NO_DEBUGGING". Otherwise it fails to build with NO_DEBUGGING
|
||
|
|
defined. (Thanks to Manuel Serrano.)
|
||
|
|
* Message about retrying suspend signals was incorrectly generated even when
|
||
|
|
flag was not set.
|
||
|
|
* Cleaned up MACOSX/NEXT root registration code. There was apparently a
|
||
|
|
separate ifdef case in GC_register_data_segments() for no reason.
|
||
|
|
* Removed MPROTECT_VDB for MACOSX port, based on one negative report.
|
||
|
|
* Arrange for gc.h and friends to be correctly installed with GNU-style
|
||
|
|
"make install".
|
||
|
|
* Enable the GNU-style build facility include C++ support in the library
|
||
|
|
with --enable-cplusplus (thanks to Thomas Maier for some of the patch).
|
||
|
|
* Mark from GC_thread_key in linux_threads.c, in case that's allocated
|
||
|
|
from the garbage collected heap, as it is with our own thread-specific
|
||
|
|
storage implementation (thanks to Jeff Sturm).
|
||
|
|
* Mark all free list header blocks if they are heap allocated. This avoids
|
||
|
|
some unnecessary tracing. And it remains correct if we clear the
|
||
|
|
root set. (Thanks to Jeff Sturm for identifying the bug.)
|
||
|
|
* Improved S390/Linux support. Add S390/Linux 64-bit support (thanks to
|
||
|
|
Ulrich Weigand).
|
||
|
|
* Corrected the spelling of GC_{M,C}ALLOC_EXPLICTLY_TYPED to
|
||
|
|
GC_{M,C}ALLOC_EXPLICITLY_TYPED in gc_typed.h. This is technically
|
||
|
|
an interface change. Based on the fact that nobody reported this,
|
||
|
|
I suspect/hope there were no clients.
|
||
|
|
* Cleaned up gc_typed.h so that (1) it adds an extern "C" declaration
|
||
|
|
when appropriate, (2) doesn't generate references to undefined internal
|
||
|
|
macros, and (3) allows easier manual construction of descriptors.
|
||
|
|
* Close the file descriptor used by GC_print_address_map().
|
||
|
|
* Set the "close-on-exec" bit for various file descriptors maintained
|
||
|
|
for the collector's internal use.
|
||
|
|
* Added a hack to find memory segments owned by the system allocator
|
||
|
|
under win32. Based on my tests, this tends to eventually find all
|
||
|
|
segments, though it may take a while. There appear to be cleaner,
|
||
|
|
but slower solutions under NT/XP. But they rely on an API that's
|
||
|
|
unsupported under 9X.
|
||
|
|
* Changed Linux PowerPC stack finding to LINUX_STACKBOTTOM. (Thanks
|
||
|
|
to Akira Tagoh for pointing out that HEURISTIC1 does not work on
|
||
|
|
64-bit kernels.)
|
||
|
|
* Added GC_set_free_space_divisor to avoid some Windows dll issues.
|
||
|
|
* Added FIXUP_POINTER, POINTER_SHIFT, POINTER_MASK to allow preprocessing
|
||
|
|
of candidate pointers for tagging, etc.
|
||
|
|
* Always lock around GC_notify_full_gc(). Simplified code for
|
||
|
|
invoking GC_notify_full_gc().
|
||
|
|
* Changed the way DATASTART is defined on FreeBSD to be robust against
|
||
|
|
an unmapped page after etext. (Thanks to Hironori Sakamoto for
|
||
|
|
tracking down the intermittent failure.)
|
||
|
|
* Made GC_enable() and GC_disable() official. Deprecated direct update
|
||
|
|
of GC_dont_gc. Changed GC_gcollect to be a noop when garbage collection
|
||
|
|
is disabled.
|
||
|
|
* Call GC_register_dynamic_libraries before stopping the world on Linux,
|
||
|
|
in order to avoid a potential deadlock due to the dl_iterate_phdr lock.
|
||
|
|
* Introduced a more general mechanism for platform-dependent code to
|
||
|
|
decide whether the main data segment should be handled separately
|
||
|
|
from dynamic libraries, or registered by GC_register_dynamic_libraries.
|
||
|
|
The latter is more reliable and easier on Linux with dl_iterate_phdr.

|
|
||
|
|
|
||
|
|
== [6.1] ==
|
||
|
|
|
||
|
|
* Added GC_MAXIMUM_HEAP_SIZE environment variable.
|
||
|
|
* Fix configure.in for MIPS/LINUX (thanks to H.J. Lu).
|
||
|
|
* Double page hash table size for -DLARGE_CONFIG.
|
||
|
|
* Integrated Bo Thorsen's X86-64 support.
|
||
|
|
* STACKBOTTOM definition for LINUX/MIPS was partially changed back
|
||
|
|
(thanks to H.J. Lu and Hiroshi Kawashima for resolving this).
|
||
|
|
* Replaced all occurrences of LINUX_DATA_START in gcconfig.h with
|
||
|
|
SEARCH_FOR_DATA_START. It doesn't hurt to fall back to a search.
|
||
|
|
And __data_start doesn't seem to get defined correctly of the GC
|
||
|
|
library is loaded with LD_PRELOAD, e.g. for leak detection.
|
||
|
|
* If the GC_find_leak environment variable is set, do a
|
||
|
|
atexit(GC_gcollect) to give us at least one chance to detect leaks.
|
||
|
|
This may report some very benign leaks, but ...
|
||
|
|
* Addeded REDIRECT_FREE. It's necessary if we want leak detection with
|
||
|
|
LD_PRELOAD.
|
||
|
|
* Defer printing of leaked objects, as for smashed objects.
|
||
|
|
* Fixed process and descriptor leak in GC_print_callers. Try for
|
||
|
|
line number even if we got function name.)
|
||
|
|
* Ported parallel GC support and thread local allocation to Alpha.
|
||
|
|
Not yet well-tested.
|
||
|
|
* Added GC_DUMP_REGULARLY and added finalization statistics to GC_dump().
|
||
|
|
* Fixed Makefile.am to mention alpha_mach_dep.S instead of the defunct
|
||
|
|
alpha_mach_dep.s.
|
||
|
|
* Incorporated a change to new_gc_alloc.h,
|
||
|
|
which should make it work with gcc3.1.
|
||
|
|
* Use alpha_mach_dep.S only on Linux. (It's not clear that this is
|
||
|
|
optimal, but it otherwise didn't build on Tru64. Thanks to Fergus Henderson.)
|
||
|
|
* Added ifdef to guard free() in os_dep.c. Otherwise we get a
|
||
|
|
compilation error on Irix (thanks to Dai Sato).
|
||
|
|
* Added an experimental version of GC_memalign to mallocx.c. This can't
|
||
|
|
always work, since we don't handle alignment requests in the hblk-level
|
||
|
|
allocator, and we can't handle arbitrary pointer displacements unless
|
||
|
|
GC_all_interior_pointers is enabled. But it should work for alignment
|
||
|
|
requests up to HBLKSIZE. This is not yet documented in the standard
|
||
|
|
places.
|
||
|
|
* Finally debugged the OSF1/Tru64 thread support. This needs more testing,
|
||
|
|
since I needed to add a somewhat unconvincing workaround for signal
|
||
|
|
delivery issues that I don't yet completely understand. But it does
|
||
|
|
pass my tests, even in parallel GC mode. Incremental GC support is
|
||
|
|
disabled if thread support is enabled, due to the signal issues.
|
||
|
|
* Eliminated name-space-incorrect definition of _cdecl from gc_cpp.h.
|
||
|
|
* Added GC_debug_malloc_replacement and GC_debug_realloc_replacement
|
||
|
|
declarations to gc.h. On IA64, this is required for REDIRECT_MALLOC
|
||
|
|
to work correctly with these.
|
||
|
|
* Fixed Linux USE_PROC_FOR_LIBRARIES to work with a 64-bit /proc format.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.1alpha5] 2002-06-19 ==
|
||
|
|
|
||
|
|
* Added GC_finalizer_mem_freed, and changed some of the code that
|
||
|
|
decided on heap expansion to look at it. Memory explicitly
|
||
|
|
deallocated by finalizers essentially needs to be counted as reclaimed
|
||
|
|
by the GC. Otherwise there are cases in which the heap can grow
|
||
|
|
infinitely. (Thanks to Mark Reichert for the test case.)
|
||
|
|
* Integrated Adam Megacz patches to not scan dynamic libraries if
|
||
|
|
we are compiling with gcc on win32. Otherwise we need structured
|
||
|
|
exception handling to deal with asynchronously unmapped root
|
||
|
|
segments, and gcc doesn't directly support that.
|
||
|
|
* Integrated Anthony Green's patch to support Wine.
|
||
|
|
* GC_OPERATOR_NEW_ARRAY was misspelled OPERATOR_NEW_ARRAY in several
|
||
|
|
places, including gc_cpp.cc (thanks to Wink Saville for pointing this out).
|
||
|
|
* Integrated Loren J. Rittle's Alpha FreeBSD patches. These also
|
||
|
|
changed the declarations of symbols like _end on many platforms to
|
||
|
|
that they wouldn't mistakenly be declared as short data symbols (suggested by
|
||
|
|
Richard Henderson).
|
||
|
|
* Integrated changes from the Debian distribution (thanks to Ryan Murray
|
||
|
|
for pointing these out).
|
||
|
|
Fix C++ comments in POWERPC port. Add ARM32
|
||
|
|
incremental GC support. Get rid of USE_GENERIC_PUSH_REGS for alpha/Linux,
|
||
|
|
this time for real. Use va_copy to get rid of cord printf problems
|
||
|
|
(finally).
|
||
|
|
* Close file descriptor used to count CPUs (thanks to Jeff Sturm for
|
||
|
|
pointing out the omission).
|
||
|
|
* Don't just drop gcj free lists in GC_start_reclaim, since that can
|
||
|
|
eventually cause the marker to see a bogus mark descriptor in the
|
||
|
|
dropped objects. The usual symptom was a very intermittent segmentation
|
||
|
|
fault in the marker. This mattered only if one of the GC_gcj_malloc
|
||
|
|
variants was used (thanks to Michael Smith, Jeff Sturm, Bryce McKinlay and
|
||
|
|
Tom Tromey for helping to track this down).
|
||
|
|
* Fixed Linux and Solaris/64 SPARC configuration (thanks to David Miller,
|
||
|
|
Jeff Sturm, Tom Tromey, and Christian Joensson).
|
||
|
|
* Fixed a typo in strdup definition (thanks to Gerard A Allan).
|
||
|
|
* Changed Makefile.direct to invoke $(CC) to assemble alpha_mach_dep.S.
|
||
|
|
This is needed on Linux. I'm not sure whether it's better or worse
|
||
|
|
on Tru64.
|
||
|
|
* Changed gc_cpp.h once more to declare operator new and friends only in
|
||
|
|
a Microsoft environment. This may need further fine tuning (thanks to
|
||
|
|
Johannes Schmidt for pointing out that the older code breaks on gcc3.0.4).
|
||
|
|
* Don't ever override strdup if it's already macro defined (thanks to
|
||
|
|
Adnan Ali for pointing out the problem).
|
||
|
|
* Changed gc_cpp.h yet again to also overload placement new. Due to the
|
||
|
|
C++ overloading rules, the other overloaded new operations otherwise hide
|
||
|
|
placement new, which causes many STL uses to break (thanks to Reza Shahidi
|
||
|
|
for reporting this, and to Matt Austern for proposing a fix).
|
||
|
|
* Integrated cygwin pthreads support from Dan Bonachea.
|
||
|
|
* Turn on DYNAMIC_LOADING for NetBSD (thanks to Krister Walfridsson).
|
||
|
|
* Changed printing code to print more complete GC times.
|
||
|
|
* Applied Mark Mitchell's Irix patch to correct some bit rot.
|
||
|
|
* Clarified which object-printing routines in dbg_mlc.c should hold
|
||
|
|
the allocation lock. Restructured the code to allow reasonable object
|
||
|
|
printing with -DREDIRECT_MALLOC.
|
||
|
|
* Fix the Linux mmap code to always start with 0x1000 as the initial hint.
|
||
|
|
Minor patches for 64-bit AIX, particularly to STACKBOTTOM (thanks to
|
||
|
|
Jeffrey Mark Siskind).
|
||
|
|
* Renamed "SUSPENDED" flag for Solaris threads support to avoid a conflict
|
||
|
|
with a system header (thanks to Philip Brown).
|
||
|
|
* Cause win32_threads.c to handle an out of range stack pointer correctly,
|
||
|
|
though currently with a warning. (Thanks to Jonathan Clark for
|
||
|
|
observing that win32 applications may temporarily use the stack
|
||
|
|
pointer for other purposes, and suggesting a fix. Unfortunately, it's
|
||
|
|
not clear that there is a complete solution to this problem.)

|
|
||
|
|
== [6.1alpha4] 2002-06-16 ==
|
||
|
|
|
||
|
|
* Fixed typo in sparc_mach_dep.S, preventing the 64-bit version from
|
||
|
|
building. Increased 64-bit heap size limit in test.c slightly, since
|
||
|
|
a functional SPARC collector seems to slightly exceed the old limits.
|
||
|
|
* Use NPRGREG in solaris_threads.c, thus printing all registers if things
|
||
|
|
go wrong.
|
||
|
|
* Added GC_MARKERS environment variable to allow use of a single marker
|
||
|
|
thread on an MP without confusing the lock implementation.
|
||
|
|
* Collect much less aggressively in incremental mode with GC_TIME_UNLIMITED.
|
||
|
|
This is really a purely generational mode, and we can afford to
|
||
|
|
postpone the collection until the heap is (nearly) full.
|
||
|
|
* Remove read() wrapper for MPROTECT_VDB. It was causing more harm than
|
||
|
|
good. It is often no longer needed if system calls avoid writing to
|
||
|
|
pointerfull heap objects.
|
||
|
|
* Fix MACOSX test in gcconfig.h (thanks to John Clements).
|
||
|
|
* Change GC_test_and_set so that it consistently has one argument.
|
||
|
|
Add spaces to ::: in powerpc assembly code in gc_locks.h (thanks to
|
||
|
|
Ryan Murray).
|
||
|
|
* Fixed a formatting error in dbg_mlc.c. Added prototype to GC_abort()
|
||
|
|
declaration (thanks to Michael Smith).
|
||
|
|
* Removed "source" argument to GC_find_start(). Eliminate GC_FIND_START().
|
||
|
|
* Added win32 recognition code in configure.in. Changed some of the
|
||
|
|
dllimport/export defines in gc.h (thanks to Adam Megacz).
|
||
|
|
* GC_malloc_many didn't set hb_last_reclaimed when it called
|
||
|
|
GC_reclaim_generic. (I'm not sure this matters much, but ...)
|
||
|
|
* Allocating uncollectible objects with debug information sometimes
|
||
|
|
allocated objects that were one byte too small, since uncollectible
|
||
|
|
objects don't have the extra byte added at the end (thanks to
|
||
|
|
Wink Saville for pointing this out).
|
||
|
|
* Added a bit more assertion checking to make sure that gcj objects
|
||
|
|
on free lists never have a nonzero second word.
|
||
|
|
* Replaced BCC_MAKEFILE with an up-to-date one (thanks to Andre Leiradella).
|
||
|
|
* Upgraded libtool, cinfigure.in and some related files to hopefully
|
||
|
|
support NetBSD/SPARC (thanks to Adrian Bunk). Unfortunately,
|
||
|
|
libtool 1.4.2 seemed to be buggy due to missing quotes in several
|
||
|
|
"test" invocations. Fixed those in the ltmain.sh script.
|
||
|
|
* Some win32-specific patches, including the introduction of
|
||
|
|
GC_CreateThread (thanks to Adam Megacz).
|
||
|
|
* Merged in gcj changes from Anthony Green to support embedded systems.
|
||
|
|
* Tried to consistently rename preprocessed assembly files with a capital
|
||
|
|
.S extension.
|
||
|
|
* Use alpha_mach_dep.S on ALPHA again. It doesn't really matter, but this
|
||
|
|
makes our distribution consistent with the gcc one, avoiding future merge
|
||
|
|
problems.
|
||
|
|
* Move GET_MEM definition into gcconfig.h. Include gcconfig.h slightly
|
||
|
|
later in gc_priv.h to avoid forward references to ptr_t.
|
||
|
|
* Add some testing of local allocation to test.c.
|
||
|
|
* Change definition of INVALID_QTID in specific.h. The -1 value was used
|
||
|
|
inconsistently, and too likely to collide with a valid stack address.
|
||
|
|
Some general clean-up of specific.[ch]. Added assertions. (Thanks
|
||
|
|
to Michael Smith for tracking down an intermittent bug to this
|
||
|
|
general area. I'm not sure it has been squashed yet, however.)
|
||
|
|
* On Pthread systems it was not safe to call GC_malloc() between fork()
|
||
|
|
and exec(). According to the applicable standards, it doesn't appear
|
||
|
|
to be safe to call malloc() or many other libc functions either, thus
|
||
|
|
it's not clear this is fixable. Added experimental support for
|
||
|
|
-DHANDLE_FORK in linux_threads.c which tries to support it. It may
|
||
|
|
succeed if libc does the right thing. I'm not sure whether it does.
|
||
|
|
(Thanks to Kenneth Schalk for pointing out this issue.)
|
||
|
|
* Documented thread local allocation primitives to require an
|
||
|
|
explicit GC_init call. GC_init_parallel is no longer declared to
|
||
|
|
be a constructor function, since that isn't portable and often
|
||
|
|
seems to lead to initialization order problems.
|
||
|
|
* Changed gc_cpp.cc and gc_cpp.h in one more attempt to make them
|
||
|
|
compatible with Visual C++ 6 (thanks to Wink Saville for the patch).
|
||
|
|
* Some more patches for Linux on HP PA-RISC.
|
||
|
|
* Added include/gc_allocator.h. It implements (hopefully) standard
|
||
|
|
conforming (as opposed to SGI-style) allocators that allocate
|
||
|
|
collectible (gc_allocator) or GC-traceable, but not collectible
|
||
|
|
(traceable_allocator) objects. This borrows heavily from libstc++,
|
||
|
|
which borrows heavily from the SGI implementation, this part of
|
||
|
|
which was written by Matt Austern. Changed test_cpp.cc to very
|
||
|
|
minimally test this.
|
||
|
|
* On Linux/X86, retry mmap with a different start argument. That should
|
||
|
|
allow the collector to use more (closer to 3GB) of the address space.
|
||
|
|
* Force 64 bit alignment with GCJ support (reflects Bryce McKinlay's
|
||
|
|
patch to the gcc tree).
|
||
|
|
* Refined the choice of sa_handler vs. sa_sigaction in GC_dirty_init
|
||
|
|
to accommodate some glibc5 systems (thanks to Dan Fandrich for the patch).
|
||
|
|
* Compensated for the fact that current versions of glibc set
|
||
|
|
__libc_stack_end incorrectly on Linux/IA64 while initialization code
|
||
|
|
is running. This could cause the collector to miss 16 bytes of
|
||
|
|
the memory stack if GC_malloc or friends where called before main().
|
||
|
|
* Mostly integrated Takis Psarogiannakopoulos' port to DG/UX Inix 86.
|
||
|
|
This will probably take another iteration to work, since his
|
||
|
|
patch conflicted with the libtool upgrade.
|
||
|
|
* Added README.arm.cross containing some information about cross-
|
||
|
|
compiling to an ARM processor from Margaret Fleck (original code provided by
|
||
|
|
Bradley D. LaRonde; edited by Andrej Cedilnik using some of solutions by
|
||
|
|
Tilman Vogel; also ported for iPAQ by Oliver Kurth).

== [6.1alpha3] 2002-02-07 ==
|
||
|
|
|
||
|
|
* Minor cleanup on the gcconfig.h section for SPARC.
|
||
|
|
* Minor fix to support Intel compiler for I386/Linux (thanks to
|
||
|
|
Sven Hartrumpf).
|
||
|
|
* Added SPARC V9 (64-bit) support (thanks to Jeff Sturm).
|
||
|
|
* Restructured the way in which we determine whether or not to keep
|
||
|
|
call stacks for debug allocation. By default SAVE_CALL_COUNT is
|
||
|
|
now zero on all platforms. Added SAVE_CALL_NARGS parameters.
|
||
|
|
If possible, use execinfo.h to capture call stack. (This should
|
||
|
|
add support for a number of new platforms, though often at
|
||
|
|
considerable runtime expense.)
|
||
|
|
* Try to print symbolic information for call stacks. On Linux, we
|
||
|
|
do this with a combination of execinfo.h and running addr2line in
|
||
|
|
a separate process. This is both much more expensive and much more
|
||
|
|
useful. Amazingly, it seems to be fast enough for most purposes.
|
||
|
|
* Redefined strdup if -DREDIRECT_MALLOC is given.
|
||
|
|
* Changed incremental collector and MPROTECT_VDB implementation so that,
|
||
|
|
under favorable conditions, pointer-free objects are not protected.
|
||
|
|
Added GC_incremental_protection_needs() to determine ahead of time whether
|
||
|
|
pointer-free objects may be protected. Replaced GC_write_hint() with
|
||
|
|
GC_remove_protection().
|
||
|
|
* Added test for GC_ENABLE_INCREMENTAL environment variable.
|
||
|
|
* Made GC_time_limit runtime configurable. Added GC_PAUSE_TIME_TARGET
|
||
|
|
environment variable.
|
||
|
|
* Eliminated GC_page_sz, a duplicate of GC_page_size.
|
||
|
|
* Caused the Solaris and Irix thread creation primitives to call
|
||
|
|
GC_init_inner().
|
||
|
|
|
||
|
|
|
||
|
|
== [6.1alpha2] 2001-12-20 ==
|
||
|
|
|
||
|
|
* No longer wrap read by default in multi-threaded applications. It was
|
||
|
|
pointed out on the libgcj list that this holds the allocation lock for
|
||
|
|
way too long if the read blocks. For now, reads into the heap are
|
||
|
|
broken with incremental collection. It's possible to turn this back on
|
||
|
|
if you make sure that read calls don't block (e.g. by calling select
|
||
|
|
first).
|
||
|
|
* Fix ifdef in Solaris_threads.h to refer to GC_SOLARIS_THREADS.
|
||
|
|
* Added check for environment variable GC_IGNORE_GCJ_INFO.
|
||
|
|
* Added printing of stop-the-world GC times if GC_PRINT_STATS environment
|
||
|
|
variable is set.
|
||
|
|
* The calloc definition in leak_detector.h was missing parentheses, and
|
||
|
|
realloc was missing a second argument to GC_REALLOC (thanks to
|
||
|
|
Elvenlord Elrond).
|
||
|
|
* Added GC_PRINT_BACK_HEIGHT environment variable and associated
|
||
|
|
code, mostly in the new file backgraph.c. See doc/README.environment.
|
||
|
|
* Added -DUSE_GLOBAL_ALLOC to work around a Windows NT issue (thanks to
|
||
|
|
Jonathan Clark).
|
||
|
|
* Integrated port to NEC EWS4800 (MIPS-based workstation, with somewhat
|
||
|
|
different address-space layout). This may help for other machines with
|
||
|
|
holes in the data segment. (Thanks to Hironori Sakamoto.)
|
||
|
|
* Changed the order in which GC_push_roots and friends push things onto
|
||
|
|
the mark stack. GC_push_all calls need to come first, since we can't
|
||
|
|
necessarily recover if those overflow the mark stack. (Thanks to
|
||
|
|
Matthew Flatt for tracking down the problem.)
|
||
|
|
* Some minor cleanups to mostly support the Intel compiler on Linux/IA64.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.1alpha1] 2001-09-22 ==
|
||
|
|
|
||
|
|
* Non-debug, atomic allocations could result in bogus smashed object
|
||
|
|
reports with debugging on (thanks to Patrick Doyle for the small test case).
|
||
|
|
* Fixed GC_get_register_stack_base (Itanium only) to work around a glibc
|
||
|
|
2.2.4 bug.
|
||
|
|
* Initial port to HP/UX on Itanium. Thread support and both 32 and 64
|
||
|
|
bit ABIs appear to work. Parallel mark support doesn't yet, due to
|
||
|
|
some inline assembly code issues. Thread local allocation does appear
|
||
|
|
to work.
|
||
|
|
* ifdef'ed out glibc2.1/Itanium workaround. I suspect nobody is using
|
||
|
|
that combination anymore.
|
||
|
|
* Added a patch to make new_gc_alloc.h usable with gcc3.0 (thanks to
|
||
|
|
Dimitris Vyzovitis for the patch).
|
||
|
|
* Debugged 64-bit support on HP/UX PA-RISC.
|
||
|
|
* Turned on dynamic loading support for FreeBSD/ELF (thanks to Peter Housel).
|
||
|
|
* Unregistering of finalizers with debugging allocation was broken (thanks
|
||
|
|
to Jani Kajala for the test case).
|
||
|
|
* Old finalizers were not returned correctly from GC_debug_register_finalizer.
|
||
|
|
* Disabled MPROTECT_VDB for Linux/M68K based on a report that it doesn't work.
|
||
|
|
* Cleaned up some statistics gathering code in reclaim.c (thanks to
|
||
|
|
Walter Bright).
|
||
|
|
* Added some support for OpenBSD/ELF/Linux (thanks to Suzuki Toshiya).
|
||
|
|
* Added Jakub Jelinek's patch to use dl_iterate_phdr for dynamic library
|
||
|
|
traversal to dyn_load.c. Changed it to weakly reference dl_iterate_phdr,
|
||
|
|
so that the old code is still used with old versions of glibc.
|
||
|
|
* Cleaned up feature test macros for various threads packages and
|
||
|
|
integrated (partially functional) FreeBSD threads code from Loren J. Rittle.
|
||
|
|
It's likely that the cleanup broke something, since it touched lots of
|
||
|
|
code. It's also likely that it fixed some unreported bugs in the
|
||
|
|
less common thread implementations, since some of the original code
|
||
|
|
didn't stand up to close scrutiny. Support for the next pthreads
|
||
|
|
implementation should be easier to add.

|
|
|
||
|
|
== [6.0] 2001-07-26 ==
|
||
|
|
|
||
|
|
* Two more bug fixes for KEEP_BACK_PTRS and DBG_HDRS_ALL.
|
||
|
|
* Fixed a stack clearing problem that resulted in SIGILL with a
|
||
|
|
misaligned stack pointer for multi-threaded SPARC builds.
|
||
|
|
* Integrated another HURD patch (thanks to Igor Khavkine).
|
||
|
|
|
||
|
|
|
||
|
|
== [6.0alpha9] ==
|
||
|
|
|
||
|
|
* added README.macros.
|
||
|
|
* Made gc.mak a symbolic link to work around winzip's tendency to ignore
|
||
|
|
hard links.
|
||
|
|
* Simplified the setting of NEED_FIND_LIMIT in os_dep.c, possibly breaking
|
||
|
|
it on untested platforms.
|
||
|
|
* Integrated initial GNU HURD port (thanks to Chris Lingard and
|
||
|
|
Igor Khavkine).
|
||
|
|
* A few more fixes for Digital Mars compiler (by Walter Bright).
|
||
|
|
* Fixed gcc version recognition. Renamed OPERATOR_NEW_ARRAY to
|
||
|
|
GC_OPERATOR_NEW_ARRAY. Changed GC_OPERATOR_NEW_ARRAY to be the default.
|
||
|
|
It can be overridden with -DGC_NO_OPERATOR_NEW_ARRAY (thanks to
|
||
|
|
Cesar Eduardo Barros).
|
||
|
|
* Changed the byte size to free-list mapping in thread local allocation
|
||
|
|
so that size 0 allocations are handled correctly.
|
||
|
|
* Fixed Linux/MIPS stackbottom for new toolchain (thanks to Ryan Murray).
|
||
|
|
* Changed finalization registration to invoke GC_oom_fn when it runs out
|
||
|
|
of memory.
|
||
|
|
* Removed lvalue cast in finalize.c. This caused some debug configurations
|
||
|
|
not to build with some non-gcc compilers.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.0alpha8] 2001-06-15 ==
|
||
|
|
|
||
|
|
* Changed GC_debug_malloc_replacement and GC_debug_realloc_replacement
|
||
|
|
so that they compile under Irix (thanks to Dave Love).
|
||
|
|
* Updated powerpc_macosx_mach_dep.s so that it works if the collector
|
||
|
|
is in a dynamic library (thanks to Andrew Begel).
|
||
|
|
* Transformed README.debugging into debugging.html, updating and
|
||
|
|
expanding it in the process. Added gcdescr.html and tree.html
|
||
|
|
from the web site to the GC distribution.
|
||
|
|
* Fixed several problems related to PRINT_BLACK_LIST. This involved
|
||
|
|
restructuring some of the marker macros.
|
||
|
|
* Fixed some problems with the sizing of objects with debug information.
|
||
|
|
Finalization was broken KEEP_BACK_PTRS or PRINT_BLACK_LIST. Reduced the
|
||
|
|
object size with SHORT_DEBUG_HDRS by another word.
|
||
|
|
* The "Needed to allocate blacklisted ..." warning had inadvertently
|
||
|
|
been turned off by default, due to a buggy test in allchblk.c. Turned
|
||
|
|
it back on.
|
||
|
|
* Removed the marker macros to deal with 2 pointers in interleaved fashion.
|
||
|
|
They were messy and the performance improvement seemed minimal. We'll
|
||
|
|
leave such scheduling issues to the compiler.
|
||
|
|
* Changed Linux/PowerPC test to also check for __powerpc__ in response
|
||
|
|
to a discussion on the gcc mailing list.
|
||
|
|
* Removed the "static" from the jmp_buf declaration in GC_generic_push_regs
|
||
|
|
(suggested by Matthew Flatt). This was causing problems in
|
||
|
|
systems that register all of their own roots. It looks far more correct
|
||
|
|
to me without the "static" anyway.
|
||
|
|
* Fixed several problems with thread local allocation of pointer-free or
|
||
|
|
typed objects. The collector was reclaiming thread-local free lists, since
|
||
|
|
it wasn't following the link fields.
|
||
|
|
* There was apparently a long-standing race condition related to
|
||
|
|
multi-threaded incremental collection. A collection could be started and
|
||
|
|
a thread stopped between the memory unprotect system call and the setting of
|
||
|
|
the corresponding dirt bit. I believe this did not affect Solaris or PCR,
|
||
|
|
which use a different dirty-bit implementation. Fixed this by installing
|
||
|
|
signal handlers with sigaction instead of signal, and disabling the thread
|
||
|
|
suspend signal while in the write-protect handler. (It is unclear
|
||
|
|
whether this scenario ever actually occurred.)
|
||
|
|
* Incremental collection did not cooperate correctly with the PARALLEL_MARK
|
||
|
|
implementation of GC_malloc_many or the local_malloc primitives. It still
|
||
|
|
doesn't work well, but it shouldn't lose memory anymore.
|
||
|
|
* Integrated some changes from the gcc source tree that I had previously
|
||
|
|
missed (thanks to Bryce McKinlay for the reminder and patch).
|
||
|
|
* Added Makefile.direct as a copy of the default Makefile, which would
|
||
|
|
normally be overwritten if configure is run.
|
||
|
|
* Changed the gc.tar target in Makefile.direct to embed the version number
|
||
|
|
in the gc directory name. This will affect future tar file distributions.
|
||
|
|
* Changed the Irix dynamic library finding code to no longer try to
|
||
|
|
eliminate writable text segments under Irix6.x, since that is probably no
|
||
|
|
longer necessary, and can apparently be unsafe on occasion (thanks to
|
||
|
|
Shiro Kawai for pointing this out).
|
||
|
|
* GC_cleanup with GC_DEBUG enabled passed a real object base address to
|
||
|
|
GC_debug_register_finalizer_ignore_self, which expected a pointer past the
|
||
|
|
debug header. Call GC_register_finalizer_ignore_self instead, even with
|
||
|
|
debugging enabled (thanks to Jean-Daniel Fekete for catching this).
|
||
|
|
* The collector didn't build with call chain saving enabled but NARGS=0.
|
||
|
|
* Fixed up the GNU-style build files enough so that they work in some
|
||
|
|
obvious cases (thanks to Maarten Thibaut).
|
||
|
|
* Added initial port to Digital Mars compiler for win32 (thanks to Walter
|
||
|
|
Bright).
|
||
|
|
|
||
|
|
|
||
|
|
== [6.0alpha7] 2001-04-19 ==
|
||
|
|
|
||
|
|
* Added GC_finalizer_notifier. Fixed GC_finalize_on_demand. (The variable
|
||
|
|
actually wasn't being tested at the right points. The build-time flag
|
||
|
|
was.)
|
||
|
|
* Added Tom Tromey's S390 Linux patch.
|
||
|
|
* Added code to push GC_finalize_now in GC_push_finalizer_structures
|
||
|
|
(thanks to Matthew Flatt).
|
||
|
|
* Added GC_push_gc_structures() to push all GC internal roots.
|
||
|
|
* Integrated some FreeBSD changes from Matthew Flatt.
|
||
|
|
* It looks like USRSTACK is not always correctly defined under Solaris.
|
||
|
|
Hacked gcconfig.h to attempt to work around the problem. The result
|
||
|
|
is not well tested. (Thanks again to Matthew Flatt for pointing this out.)
|
||
|
|
* Added Ji-Yong Chung's win32 threads and C++ fixes.
|
||
|
|
* Arranged for hpux_test_and_clear.s to no longer be needed or built.
|
||
|
|
It was causing build problems with gas, and it's not clear this is
|
||
|
|
better than the pthreads alternative on this platform.
|
||
|
|
* Some MINGW32 fixes from Hubert Garavel.
|
||
|
|
* Added initial Hitachi SH4 port from Kaz Kojima.
|
||
|
|
* Ported thread-local allocation and parallel mark code to HP/UX on PA_RISC.
|
||
|
|
* Made include/gc_mark.h more public and separated out the really private
|
||
|
|
pieces. This is probably still not quite sufficient for clients that
|
||
|
|
want to supply their own kind of type information. But it's a start.
|
||
|
|
This involved lots of identifier renaming to make it namespace clean.
|
||
|
|
* Added GC_dont_precollect for clients that need complete control over
|
||
|
|
the root set.
|
||
|
|
* GC_is_visible didn't do the right thing with gcj objects. (Not that
|
||
|
|
many people are likely to care, but ...)
|
||
|
|
* Don't redefine read with GC_USE_LD_WRAP.
|
||
|
|
* Initial port to LINUX/HP_PA. Incremental collection and threads are not
|
||
|
|
yet supported. (Incremental collection should work if you have the
|
||
|
|
right kernel. Threads may work with a sufficiently patched pthread
|
||
|
|
library.)
|
||
|
|
* Changed gcconfig.h to recognize __i386__ as an alternative to i386 in
|
||
|
|
many places (thanks to Benjamin Lerman).
|
||
|
|
* Made win32_threads.c more tolerant of detaching a thread that it didn't
|
||
|
|
know about (thanks to Paul Nash).
|
||
|
|
* Added Makefile.am and configure.in from gcc to the distribution, with
|
||
|
|
minimal changes. For the moment, those are just placeholders. In the
|
||
|
|
future, we're planning to switch to a GNU-style build environment for
|
||
|
|
Un*x-like systems, though the old Makefile will remain as a backup.
|
||
|
|
* Turned off STUBBORN_ALLOC by default, and added it back as a Makefile
|
||
|
|
option.
|
||
|
|
* Redistributed some functions between malloc.c and mallocx.c, so that
|
||
|
|
simple statically linked apps no longer pull in mallocx.o.
|
||
|
|
* Changed large object allocation to clear the first and last few words
|
||
|
|
of each block before releasing the lock. Otherwise the marker could see
|
||
|
|
objects with nonsensical type descriptors.
|
||
|
|
* Fixed a couple of subtle problems that could result in not recognizing
|
||
|
|
interior pointers from the stack. (I believe these were introduced
|
||
|
|
in 6.0alpha6.)
|
||
|
|
* GC_debug_free_inner called GC_free, which tried to reacquire the
|
||
|
|
allocator lock, and hence deadlocked. (DBG_HDRS_ALL probably never worked
|
||
|
|
with threads.)
|
||
|
|
* Fixed several problems with back traces. Accidental references to a free
|
||
|
|
list could cause the free list pointer to be overwritten by a back pointer.
|
||
|
|
There seemed to be some problems with the encoding of root and finalizer
|
||
|
|
references.
|
||
|
|
|
||
|
|
|
||
|
|
== [6.0alpha6] ==
|
||
|
|
|
||
|
|
* Changed the definition of DATASTART on ALPHA and IA64, where data_start
|
||
|
|
and __data_start are not defined by earlier versions of glibc. This might
|
||
|
|
need to be fixed on other platforms as well.
|
||
|
|
* Changed the way the stack base and backing store base are found on IA64.
|
||
|
|
This should now remain reliable on future kernels. But since it relies
|
||
|
|
on /proc, it will no longer work in the simulated NUE environment.
|
||
|
|
* Made the call to random() in dbg_mlc.c with -DKEEP_BACK_PTRS dependent
|
||
|
|
on the OS. On non-Unix systems, rand() should be used instead. Handled
|
||
|
|
small RAND_MAX (thanks to Peter Ross for pointing this out).
|
||
|
|
* Fixed the cord make rules to create the cord subdirectory, if necessary
|
||
|
|
(thanks to Doug Moen).
|
||
|
|
* Changed fo_object_size calculation in finalize.c. Turned finalization
|
||
|
|
of non-heap object into a no-op. Removed anachronism from GC_size()
|
||
|
|
implementation.
|
||
|
|
* Changed GC_push_dirty call in solaris_threads.c to GC_push_selected.
|
||

It was missed in a previous renaming (thanks to Vladimir Tsichevski
|
||
|
|
for pointing this out).
|
||
|
|
* Arranged to not mask SIGABRT in linux_threads.c (thanks to Bryce McKinlay).
|
||
|
|
* Added GC_no_dls hook for applications that want to register their own
|
||
|
|
roots.
|
||
|
|
* Integrated Kjetil Matheussen's Amiga changes.
|
||
|
|
* Added FREEBSD_STACKBOTTOM. Changed the X86/FreeBSD port to use it
|
||
|
|
(thanks to Matthew Flatt).
|
||
|
|
* Added pthread_detach interception for platforms supported by linux_threads.c
|
||
|
|
and irix_threads.c.
|
||
|
|
* Changed the USE_MMAP code to check for the case in which we got the
|
||
|
|
high end of the address space, i.e. mem_ptr + mem_sz == 0. It appears
|
||
|
|
that this can happen under Solaris 7. It seems to be allowed by what
|
||
|
|
I would claim is an oversight in the mmap specification. (Thanks to
|
||
|
|
Toshio Endo for pointing out the problem.)
|
||
|
|
* Cleanup of linux_threads.c. Some code was originally cloned from
|
||
|
|
irix_threads.c and now unnecessary. Some comments were obviously wrong.
|
||
|
|
* (Mostly) fixed a longstanding problem with setting of dirty bits from
|
||
|
|
a signal handler. In the presence of threads, dirty bits could get lost,
|
||
|
|
since the etting of a bit in the bit vector was not atomic with respect
|
||
|
|
to other updates. The fix is 100% correct only for platforms for which
|
||
|
|
GC_test_and_set is defined. The goal is to make that all platforms with
|
||
|
|
thread support. Matters only if incremental GC and threads are both
|
||
|
|
enabled.
|
||
|
|
* made GC_all_interior_pointers (a.k.a. ALL_INTERIOR_POINTERS) an
|
||
|
|
initialization time, instead of build-time option. This is a
|
||
|
|
nontrivial, high risk change. It should slow down the code measurably
|
||
|
|
only if MERGE_SIZES is not defined, which is a very nonstandard
|
||
|
|
configuration.
|
||
|
|
* Added doc/README.environment, and implemented what it describes. This
|
||
|
|
allows a number of additional configuration options to be set through
|
||
|
|
the environment. It documents a few previously undocumented options.
|
||
|
|
* Integrated Eric Benson's leak testing improvements.
|
||
|
|
* Removed the option to throw away the beginning of each page (DISCARD_WORDS).
|
||
|
|
This became less and less useful as processors enforce stricter alignment.
|
||
|
|
And it hadn't been tested in ages, and was thus probably broken anyway.

|
|
||
|
|
|
||
|
|
== [6.0alpha5] ==
|
||
|
|
|
||
|
|
* Changed the definition of GC_pause in linux_threads.c to use a volatile
|
||
|
|
asm. Some versions of gcc apparently optimize away writes to local volatile
|
||
|
|
variables. This caused poor locking behavior starting at about
|
||
|
|
4 processors.
|
||
|
|
* Added GC_start_blocking(), GC_end_blocking() calls and wrapper for sleep
|
||
|
|
to linux_threads.c.
|
||
|
|
The first two calls could be used to generally avoid sending GC signals to
|
||
|
|
blocked threads, avoiding both premature wakeups and unnecessary overhead.
|
||
|
|
* Fixed a serious bug in thread-local allocation. At thread termination,
|
||
|
|
GC_free could get called on small integers. Changed the code for thread
|
||
|
|
termination to more efficiently return left-over free-lists.
|
||
|
|
* Integrated Kjetil Matheussen's BeOS support.
|
||
|
|
* Rearranged the directory structure to create the doc and tests
|
||
|
|
subdirectories.
|
||
|
|
* Sort of integrated Eric Benson's patch for OSF1. This provided basic
|
||
|
|
OSF1 thread support by suitably extending hpux_irix_threads.c. Based
|
||
|
|
on earlier email conversations with David Butenhof, I suspect that it
|
||
|
|
will be more reliable in the long run to base this on linux_threads.c
|
||
|
|
instead. Thus I attempted to patch up linux_threads.c based on Eric's code.
|
||
|
|
The result is almost certainly broken, but hopefully close enough that
|
||
|
|
someone with access to a machine can pick it up.
|
||
|
|
* Integrated lots of minor changes from the NetBSD distribution. (These
|
||
|
|
were supplied by David Brownlee. I'm not sure about the original
|
||
|
|
authors.)
|
||
|
|
* Hacked a bit more on the HP/UX thread-support in linux_threads.c. It
|
||
|
|
now appears to work in the absence of incremental collection. Renamed
|
||
|
|
hpux_irix_threads.c back to irix_threads.c, and removed the attempt to
|
||
|
|
support HPUX there.
|
||
|
|
* Changed gc.h to define _REENTRANT in cases in which it should already
|
||
|
|
have been defined. It is still safer to also define it on the command
|
||
|
|
line.
|

|
|
||
|
|
|
||
|
|
== [6.0alpha4] ==
|
||
|
|
|
||
|
|
* Moved up the detection of mostly full blocks to the initiation of the
|
||
|
|
sweep phase. This eliminates some lock contention in the PARALLEL_MARK case,
|
||
|
|
as multiple threads try to look at mostly full blocks concurrently.
|
||
|
|
* Restored the code in GC_malloc_many that grabs a prefix of the global
|
||
|
|
free list. This avoids the case in which every GC_malloc_many call
|
||
|
|
tries and fails to allocate a new heap block, and the returns a single
|
||
|
|
object from the global free list.
|
||
|
|
* Some minor fixes in new_hblk.c. (Attempted to build free lists in order
|
||
|
|
of increasing addresses instead of decreasing addresses for cache performance
|
||
|
|
reasons. But this seems to be only a very minor gain with -DEAGER_SWEEP,
|
||
|
|
and a loss in other cases. So the change was backed out.)
|
||
|
|
* Fixed some of the documentation (thanks in large part to Fergus Henderson).
|
||
|
|
* Fixed the Linux USE_PROC_FOR_LIBRARIES code to deal with apps that perform
|
||
|
|
large numbers of mmaps (thanks to Eric Benson). Also fixed that code to
|
||
|
|
deal with short reads.
|
||
|
|
* Added GC_get_total_bytes().
|
||
|
|
* Fixed leak detection mode to avoid spurious messages under linuxthreads.
|
||
|
|
(This should also now be easy for the other supported threads packages.
|
||
|
|
But the code is tricky enough that I'm hesitant to do it without being able
|
||
|
|
to test. Everything allocated in the GC thread support itself should be
|
||
|
|
explicitly deallocated.)
|
||
|
|
* Made it possible (with luck) to redirect malloc to GC_local_malloc.
|
||
|

|
|
||
|
|
== [6.0alpha3] 2000-09-26 ==
|
||
|
|
|
||
|
|
* Fixed the /proc/self/maps code to not seek, since that apparently is not
|
||
|
|
reliable across all interesting kernels.
|
||
|
|
* Fixed some compilation problems in the absence of PARALLEL_MARK
|
||
|
|
(introduced in alpha2).
|
||
|
|
* Fixed an algorithmic problem with PARALLEL_MARK. If work needs to
|
||
|
|
be given back to the main mark "stack", the BOTTOM entries of the local
|
||
|
|
stack should be given away, not the top ones. This has substantial
|
||
|
|
performance impact, especially for > 2 processors, from what I can tell.
|
||
|
|
* Extracted gc_lock.h from gc_priv.h. This should eventually make it a
|
||
|
|
bit easier to avoid including gc_priv.h in clients.
|
||
|
|
* Moved all include files to include/ and removed duplicate links to the
|
||
|
|
same file. The old scheme was a bad idea because it was too easy to get the
|
||
|
|
copies out of sync, and many systems don't support hard links.
|
||
|
|
Unfortunately, it's likely that I broke some of the non-Unix Makefiles in
|
||
|
|
the process, although I tried to update them appropriately.
|
||
|
|
* Removed the partial support for a copied nursery. It's not clear that
|
||
|
|
this would be a tremendous win, since we don't consistently lose to
|
||
|
|
generational copying collectors. And it would significantly complicate
|
||
|
|
many things. May be reintroduced if/when it really turns out to win.
|
||
|
|
* Removed references to IRIX_JDK_THREADS, since I believe there never
|
||
|
|
were and never will be any clients.
|
||
|
|
* Added some code to linux_threads.c to possibly support HPUX threads
|
||
|
|
using the Linux code. Unfortunately, it doesn't work yet, and is
|
||
|
|
currently disabled.
|
||
|
|
* Added support under Linux/X86 for saving the call chain, both in (debug)
|
||
|
|
objects for client debugging, and in GC_arrays._last_stack for GC
|
||
|
|
debugging. This was previously supported only under Solaris. It is
|
||
|
|
not enabled by default under X86, since it requires that code be compiled
|
||
|
|
to explicitly gave frame pointers on the call stack. (With gcc this
|
||
|
|
currently happens by default, but is often turned off explicitly.)
|
||
|
|
To turn it on, define SAVE_CALL_CHAIN.

|
|
||
|
|
|
||
|
|
== [6.0alpha2] ==
|
||
|
|
|
||
|
|
* Added USE_MARK_BYTES to reduce the need for compare-and-swap on platforms
|
||
|
|
for which that's expensive.
|
||
|
|
* Fixed a locking bug ib GC_gcj_malloc and some locking assertion problems.
|
||
|
|
* Added a missing volatile to OR_WORD and renamed the parameter to
|
||
|
|
GC_compare_and_swap so it's not a C++ reserved word (thanks to
|
||
|
|
Toshio Endo for pointing out both of those).
|
||
|
|
* Changed Linux dynamic library registration code to look at /proc/self/maps
|
||
|
|
instead of the rld data structures when REDIRECT_MALLOC is defined.
|
||
|
|
Otherwise some of the rld data data structures may be prematurely garbage
|
||
|
|
collected.
|
||
|
|
* Fixed USE_LD_WRAP a bit more, so it should now work without threads.
|
||
|
|
* Renamed XXX_THREADS macros to GC_XXX_THREADS for namespace correctness.
|
||
|
|
Temporarily added some backward compatibility definitions. Renamed
|
||
|
|
USE_LD_WRAP to GC_USE_LD_WRAP.
|
||
|
|
* Many MACOSX POWERPC changes, some additions to the gctest output, and
|
||
|
|
a few minor generic bug fixes (thanks to Dietmar Planitzer).
|
||
|
|
|
||
|
|
|
||
|
|
== [6.0alpha1] ==
|
||
|
|
|
||
|
|
* Added HP/PA prefetch support.
|
||
|
|
* Added -DDBG_HDRS_ALL and -DSHORT_DBG_HDRS to reduce the cost and improve
|
||
|
|
the reliability of generating pointer backtrace information, e.g. in
|
||
|
|
the Bigloo environment.
|
||
|
|
* Added parallel marking support (-DPARALLEL_MARK). This currently
|
||
|
|
works only under IA32 and IA64 Linux, but it shouldn't be hard to adapt
|
||
|
|
to other platforms. This is intended to be a lighter-weight (less
|
||
|
|
new code, probably not as scalable) solution than the work by Toshio Endo
|
||
|
|
et al, at the University of Tokyo. A number of their ideas were
|
||
|
|
reused, though the code wasn't, and the underlying data structure
|
||
|
|
is significantly different. In particular, we keep the global mark
|
||
|
|
stack as a single shared data structure, but most of the work is done
|
||
|
|
on smaller thread-local mark stacks.
|
||
|
|
* Changed GC_malloc_many to be cheaper, and to require less mutual exclusion
|
||
|
|
with -DPARALLEL_MARK.
|
||
|
|
* Added full support for thread local allocation under Linux
|
||
|
|
(-DTHREAD_LOCAL_ALLOC). This is a thin veneer on GC_malloc_many, and
|
||
|
|
should be easily portable to other platforms, especially those that
|
||
|
|
support pthreads.
|
||
|
|
* CLEAR_DOUBLE was not always getting invoked when it should have been.
|
||
|
|
* GC_gcj_malloc and friends used different out of memory handling than
|
||
|
|
everything else, probably because I forgot about one when I implemented
|
||
|
|
the other. They now both call GC_oom_fn(), not GC_oom_action().
|
||
|
|
* Integrated Jakub Jelinek's fixes for Linux/SPARC.
|
||
|
|
* Moved GC_objfreelist, GC_aobjfreelist, and GC_words_allocd out of
|
||
|
|
GC_arrays, and separately registered the first two as excluded roots.
|
||
|
|
This makes code compiled with gc_inl.h less dependent on the
|
||
|
|
collector version. (It would be nice to remove the inclusion of
|
||
|
|
gc_priv.h by gc_inl.h completely, but we're not there yet. The
|
||
|
|
locking definitions in gc_priv.h are still referenced.)
|
||
|
|
This change was later conditioned on SEPARATE_GLOBALS, which
|
||
|
|
is not defined by default, since it involves a performance hit.
|
||
|
|
* Register GC_obj_kinds separately as an excluded root region. The
|
||
|
|
attempt to register it with GC_arrays was usually failing. (This wasn't
|
||
|
|
serious, but seemed to generate some confusion.)
|
||
|
|
* Moved backptr.h to gc_backptr.h.

|
||
|
|
Shawn Wagner for actually testing this).
|
||
|
|
* Fixed GC_is_thread_stack in solaris_threads.c. It forgot to return a value
|
||
|
|
in the common case.
|
||
|
|
* Fixed another silly syntax problem in GC_double_descr (thanks to
|
||
|
|
Fergus Henderson for finding it).
|
||
|
|
* Fixed a GC_gcj_malloc bug: It tended to release the allocator lock twice.

== [5.3] 2000-09-24 ==
|

||
|
|
* Fixed _end declaration for OSF1.
|
||
|
|
* There were lots of spurious leak reports in leak detection mode, caused
|
||
|
|
by the fact that some pages were not being swept, and hence unmarked
|
||
|
|
objects weren't making it onto free lists. (This bug dated back to 5.0.)
|
||
|
|
* Fixed a typo in the liblinuxgc.so Makefile rule.
|
||
|
|
* Added the GetExitCodeThread to Win32 GC_stop_world to (mostly) work
|
||
|
|
around a Windows 95 GetOpenFileName problem (thanks to Jacob Navia).

|

|
|
|
||
|
|
== [5.2] ==
|
||
|
|
|
||
|
|
* dyn_load.c declared GC_scratch_last_end_ptr as an extern even if it
|
||
|
|
was defined as a macro. This prevented the collector from building on
|
||
|
|
Irix.
|
||
|
|
* We quietly assumed that indirect mark descriptors were never 0.
|
||
|
|
Our own typed allocation interface violated that. This could result
|
||
|
|
in segmentation faults in the marker with typed allocation.
|
||
|
|
* Fixed a _DUSE_MUNMAP bug in the heap block allocation code (thanks to
|
||
|
|
Ben Hutchings for the patch).
|
||
|
|
* Taught the collector about VC++ handling array operator new (thanks to
|
||
|
|
Ben Hutchings for the patch).
|
||
|
|
* The two copies of gc_hdrs.h had diverged. Made one a link to the other
|

|
again.

* Fixed a gc.h header bug which showed up under Irix (thanks to Dan Sullivan).
|
||
|
|
* Fixed a typo in GC_double_descr in typd_mlc.c.
|
||
|
|
This probably could result in objects described by array descriptors not
|
||
|
|
getting traced correctly (thanks to Ben Hutchings for pointing this out).
|
||
|
|
* The block nearly full tests in reclaim.c were not correct for 64 bit
|
||
|
|
environments. This could result in unnecessary heap growth under unlikely
|
||
|
|
conditions.

== [5.0] ==

|
|
|

* Fixed threadlibs.c for linux threads. -DUSE_LD_WRAP was broken and
|
||
|
|
-ldl was omitted. Fixed Linux stack finding code to handle
|
||
|
|
-DUSE_LD_WRAP correctly.
|
||
|
|
* Added MSWIN32 exception handler around marker, so that the collector
|
||
|
|
can recover from root segments that are unmapped during the collection.
|
||
|
|
This caused occasional failures under Windows 98, and may also be
|
||
|
|
an issue under Windows NT/2000.

* -DREDIRECT_MALLOC was broken in alpha6. Fixed.
|
||
|
|
* Cleaned up gc_ccp.h slightly, thus also causing the HP C++ compiler to
|
||
|
|
accept it.
|
||
|
|
* Removed accidental reference to dbg_mlc.c, which caused dbg_mlc.o to be
|
||
|
|
linked into every executable.
|
||
|
|
* Added PREFETCH to bitmap marker. Changed it to use the header cache.
|
||
|
|
* GC_push_marked sometimes pushed one object too many, resulting in a
|
||
|
|
segmentation fault in GC_mark_from_mark_stack. This was probably an old
|
||
|
|
bug. It finally showed up in gctest on win32.
|
||
|
|
* Gc_priv.h erroneously #defined GC_incremental to be TRUE instead of FALSE
|
||
|
|
when SMALL_CONFIG was defined. This was no doubt a major performance bug for
|
||
|
|
the default win32 configuration.
|
||
|
|
* Removed -DSMALL_CONFIG from NT_MAKEFILE. It seemed like an anachronism now
|
||
|
|
that the average PC has 64MB or so.
|
||
|
|
* Integrated Bryce McKinlay's patches for linux threads and dynamic loading
|
||
|
|
from the libgcj tree. Turned on dynamic loading support for Linux/PPC.
|
||
|
|
* Changed the stack finding code to use environ on HP/UX (thanks
|
||
|
|
to Gustavo Rodriguez-Rivera for the suggestion). This should
|
||
|
|
probably be done on other platforms, too. Since I can't test those, that'll
|

wait until after 5.0.

== [5.0alpha6] ==

|
|
||
|
|
* GC_malloc_explicitly_typed and friends sometimes failed to
|
||
|
|
initialize first word.
|
||
|
|
* Added allocation routines and support in the marker for mark descriptors
|
||
|
|
in a type structure referenced by the first word of an object. This was
|
||
|
|
introduced to support gcj, but hopefully in a way that makes it
|
||
|
|
generically useful.
|
||
|
|
* Added GC_requested_heapsize, and inhibited collections in non-incremental
|
||
|
|
mode if the actual used heap size is less than what was explicitly
|
||
|
|
requested.
|
||
|
|
* The Solaris pthreads version of GC_pthread_create didn't handle a NULL
|
||
|
|
attribute pointer. Solaris thread support used the wrong default thread
|
||
|
|
stack size (thanks to Melissa O'Neill for the patch).
|
||
|
|
* Changed PUSH_CONTENTS macro to no longer modify first parameter.
|
||
|
|
This usually doesn't matter, but it was certainly an accident waiting
|
||
|
|
to happen ...
|
||
|
|
* Added GC_register_finalizer_no_order and friends to gc.h. They're
|
||
|
|
needed by Java implementations.
|
||
|
|
* Integrated a fix for a win32 deadlock resulting from clock() calling
|
||
|
|
malloc (thanks to Chris Dodd).
|
||
|
|
* Integrated Hiroshi Kawashima's port to Linux/MIPS. This was designed
|
||
|
|
for a handheld platform, and may or may not be sufficient for other
|
||
|
|
machines.
|
||
|
|
* Fixed a va_arg problem with the %c specifier in cordprnt.c. It appears
|
||
|
|
that this was always broken, but recent versions of gcc are the first to
|
||
|
|
report the (statically detectable) bug.
|
||
|
|
* Added an attempt at a more general solution to dlopen races/deadlocks.
|
||
|
|
GC_dlopen now temporarily disables collection. Still not ideal, but ...
|
||
|
|
* Added -DUSE_I686_PREFETCH, -DUSE_3DNOW_PREFETCH, and support for IA64
|
||
|
|
prefetch instructions. May improve performance measurably, but I'm not
|
||
|
|
sure the code will run correctly on processors that don't support the
|
||
|
|
instruction. Won't build except with very recent gcc.
|
||
|
|
* Added caching for header lookups in the marker. This seems to result
|
||
|
|
in a barely measurable performance gain. Added support for interleaved
|
||
|
|
lookups of two pointers, but unconfigured that since the performance
|
||
|
|
gain is currently near zero, and it adds to code size.
|
||
|
|
* Changed Linux DATA_START definition to check both data_start and
|
||
|
|
__data_start, since nothing else seems to be portable.
|
||
|
|
* Added -DUSE_LD_WRAP to optionally take advantage of the GNU ld function
|
||
|
|
wrapping mechanism. Probably currently useful only on Linux.
|
||
|
|
* Moved some variables for the scratch allocator into GC_arrays (suggested
|
||
|
|
by Martin Hirzel).
|
||
|
|
* Fixed a win32 threads bug that caused the collector to not look for
|
||
|
|
interior pointers from one of the thread stacks without
|
||
|
|
ALL_INTERIOR_POINTERS (thanks to Jeff Sturm).
|
||
|
|
* Added Mingw32 support (thanks to Jeff Sturm for the patch).
|
||
|
|
* Changed the alpha port to use the generic register scanning code instead
|
||
|
|
of alpha_mach_dep.s. Alpha_mach_dep.s doesn't look for pointers in fp
|
||
|
|
registers, but gcc sometimes spills pointers there (thanks to Manuel Serrano
|
||
|
|
for helping debug this). Changed the IA64 code to
|
||
|
|
do something similar for similar reasons.
|
||
|
|

|
|
|
||
|
|
== [5.0alpha4] 1999-10-30 ==
|
||
|
|
|
||
|
|
* Added protection fault handling patch for Linux/M68K from Fergus
|
||
|
|
Henderson and Roman Hodek.
|
||
|
|
* Removed the tests for SGI_SOURCE in new_gc_alloc.h. This was causing that
|
||
|
|
interface to fail on non-SGI platforms.
|
||
|
|
* Changed the Linux stack finding code to use /proc, after changing it
|
||
|
|
to use HEURISTIC1 (thanks to David Mossberger for pointing out /proc hook).
|
||
|
|
* Added HP/UX incremental GC support and HP/UX 11 thread support.
|
||
|
|
Thread support is currently still flaky.
|
||
|
|
* Added basic Linux/IA64 support.
|
||
|
|
* Integrated Anthony Green's PicoJava support.
|
||
|
|
* Integrated Scott Ananian's StrongARM/NetBSD support.
|
||
|
|
* Fixed some fairly serious performance bugs in the incremental
|
||
|
|
collector. These have probably been there essentially forever.
|
||
|
|
(Mark bits were sometimes set before scanning dirty pages.
|
||
|
|
The reclaim phase unnecessarily dirtied full small object pages.)
|
||
|
|
* Changed the reclaim phase to ignore nearly full pages to avoid
|
||
|
|
touching them.
|
||
|
|
* Limited GC_black_list_spacing to roughly the heap growth increment.
|
||
|
|
* Changed full collection triggering heuristic to decrease full GC
|
||
|
|
frequency by default, but to explicitly trigger full GCs during
|
||
|
|
heap growth. This doesn't always improve things, but on average it's
|
||
|
|
probably a win.
|
||
|
|
* GC_debug_free(0, ...) failed (thanks to Fergus Henderson for the
|
||
|
|
bug report and fix).
|
||
|
|
|
||
|
|
|
||
|
|
== [5.0alpha3] 1999-09-15 ==
|
||
|
|
|
||
|
|
(Also known as 4.15alpha3.)
|
||
|
|
* Added some highly incomplete code to support a copied young generation.
|
||
|
|
Comments on nursery.h are appreciated.
|
||
|
|
* Changed -DFIND_LEAK, -DJAVA_FINALIZATION, and -DFINALIZE_ON_DEMAND,
|
||
|
|
so the same effect could be obtained with a runtime switch. This is
|
||
|
|
a step towards standardizing on a single dynamic GC library.
|
||
|
|
* Significantly changed the way leak detection is handled, as a consequence
|
||
|
|
of the above.
|
||
|
|
|
||
|
|
|
||
|
|
== [5.0alpha2] 1999-07-23 ==
|
||
|
|
|
||
|
|
* Fixed bugs introduced in alpha1 (OpenBSD & large block initialization).
|
||
|
|
* Added -DKEEP_BACK_PTRS and backptr.h interface. (The implementation
|
||
|
|
idea came from Alan Demers.)
|
||
|
|
|
||
|
|
|
||
|
|
== [5.0alpha1] 1999-06-30 ==
|
||
|
|
|
||
|
|
(Also known as 4.15alpha1.)
|
||
|
|
* Reworked large block allocator. Now uses multiple doubly linked free
|
||
|
|
lists to approximate best fit.
|
||
|
|
* Changed heap expansion heuristic. Entirely free blocks are no longer
|
||
|
|
counted towards the heap size. This seems to have a major impact on
|
||
|
|
heap size stability; the old version could expand the heap way too
|
||
|
|
much in the presence of large block fragmentation.
|
||
|
|
* added -DGC_ASSERTIONS and some simple assertions inside the collector.
|
||
|
|
This is mainlyt for collector debugging.
|
||
|
|
* added -DUSE_MUNMAP to allow the heap to shrink. Supported on only
|
||
|
|
a few UNIX-like platforms for now.
|
||
|
|
* added GC_dump_regions() for debugging of fragmentation issues.
|
||
|
|
* Changed PowerPC pointer alignment under Linux to 4.
|
||
|
|
* Changed the Linux/Alpha port to walk the data segment backwards until
|
||
|
|
it encounters a SIGSEGV. The old way to find the start of the data
|
||
|
|
segment broke with a recent release.
|
||
|
|
* cordxtra.c needed to call GC_REGISTER_FINALIZER instead of
|
||
|
|
GC_register_finalizer, so that it would continue to work with GC_DEBUG.
|
||
|
|
* allochblk sometimes cleared the wrong block for debugging purposes
|
||
|
|
when it dropped blacklisted blocks. This could result in spurious
|
||
|
|
error reports with GC_DEBUG.
|
||
|
|
* added MACOS X Server support (thanks to Andrew Stone).
|
||
|
|
* Changed the Solaris threads code to ignore stack limits > 8 MB with
|
||
|
|
a warning. Empirically, it is not safe to access arbitrary pages
|
||
|
|
in such large stacks. And the dirty bit implementation does not
|
||
|
|
guarantee that none of them will be accessed.
|
||
|
|
* Integrated Martin Tauchmann's Amiga changes.
|
||
|
|
* Integrated James Dominy's OpenBSD/SPARC port.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.14] 1999-04-16 ==
|
||
|
|
|
||
|
|
* changed STACKBOTTOM for DJGPP (thanks to Salvador Eduardo Tropea).
|
||
|
|
|
||
|
|
|
||
|
|
== [4.14alpha2] 1999-03-26 ==
|
||
|
|
|
||
|
|
* -DSMALL_CONFIG did not work reliably with large (> 4K) pages.
|
||
|
|
Recycling the mark stack during expansion could result in a size
|
||
|
|
zero heap segment, which confused things. (This was probably also an
|
||
|
|
issue with the normal config and huge pages.)
|
||
|
|
* Did more work to make sure that callee-save registers were scanned
|
||
|
|
completely, even with the setjmp-based code. Added USE_GENERIC_PUSH_REGS
|
||
|
|
macro to facilitate testing on machines I have access to.
|
||
|
|
* Added code to explicitly push register contents for win32 threads.
|
||
|
|
This seems to be necessary. (Thanks to Pierre de Rop.)
|
||
|
|
|
||
|
|
|
||
|
|
== [4.14alpha1] 1999-03-10 ==
|
||
|
|
|
||
|
|
* Fixed GC_print_source_ptr to not use a prototype.
|
||
|
|
* generalized CYGWIN test.
|
||
|
|
* gc::new did the wrong thing with PointerFreeGC placement (thanks to
|
||
|
|
Rauli Ruohonen).
|
||
|
|
* In the ALL_INTERIOR_POINTERS (default) case, some callee-save register
|
||
|
|
values could fail to be scanned if the register was saved and
|
||
|
|
reused in a GC frame. This showed up in verbose mode with gctest
|
||
|
|
compiled with an unreleased SGI compiler. I vaguely recall an old
|
||
|
|
bug report that may have been related. The bug was probably quite old.
|
||
|
|
(The problem was that the stack scanning could be deferred until
|
||
|
|
after the relevant frame was overwritten, and the new save location
|
||
|
|
might be outside the scanned area. Fixed by more eager stack scanning.)
|
||
|
|
* PRINT_BLACK_LIST had some problems. A few source addresses were garbage.
|
||
|
|
* Replaced Makefile.dj and added -I flags to cord make targets (thanks to
|
||
|
|
Gary Leavens).
|
||
|
|
* GC_try_to_collect was broken with the non-incremental collector.
|
||
|
|
* gc_cleanup destructors could pass the wrong address to
|
||
|
|
GC_register_finalizer_ignore_self in the presence of multiple
|
||
|
|
inheritance (thanks to Darrell Schiebel).
|
||
|
|
* Changed PowerPC Linux stack finding code.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.13] 1999-02-19 ==
|
||
|
|
|
||
|
|
* Fixed a crucial bug in the Watcom port. There was a redundant declaration
|
||
|
|
of GC_push_one in gc_priv.h.
|
||
|
|
* Added FINALIZE_ON_DEMAND.
|
||
|
|
* Fixed some pre-ANSI cc problems in test.c.
|
||
|
|
* Removed getpagesize() use for Solaris. It seems to be missing in one
|
||
|
|
or two versions.
|
||
|
|
* Fixed bool handling for SPARCCompiler version 4.2.
|
||
|
|
* Fixed some files in include that had gotten unlinked from the main
|
||
|
|
copy.
|
||
|
|
* Some RS/6000 fixes (missing casts). (Thanks to Toralf Foerster.)
|
||
|
|
* Fixed several problems in GC_debug_realloc, affecting mostly the
|
||
|
|
FIND_LEAK case.
|
||
|
|
* GC_exclude_static_roots contained a buggy unsigned comparison to
|
||
|
|
terminate a loop (thanks to Wilson Ho).
|
||
|
|
* CORD_str failed if the substring occurred at the last possible position.
|
||
|
|
(Only affects cord users.)
|
||
|
|
* Fixed Linux code to deal with RedHat 5.0 and integrated Peter Bigot's
|
||
|
|
os_dep.c code for dealing with various Linux versions.
|
||
|
|
* Added workaround for Irix pthreads sigaction bug and possible signal
|
||
|
|
misdirection problems.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.13alpha3] 1998-12-08 ==
|
||
|
|
|
||
|
|
* Fixed MSWIN32 recognition test, which interfered with cygwin.
|
||
|
|
* Removed unnecessary gc_watcom.asm from distribution. Removed
|
||
|
|
some obsolete README.win32 text.
|
||
|
|
* Added Alpha Linux incremental GC support (thanks to Philipp Tomsich
|
||
|
|
for code for retrieving the fault address in a signal handler).
|
||
|
|
Changed Linux signal handler context argument to be a pointer.
|
||
|
|
* Took care of some new warnings generated by the 7.3 SGI compiler.
|
||
|
|
* Integrated Phillip Musumeci's FreeBSD/ELF fixes.
|
||
|
|
* -DIRIX_THREADS was broken with the -o32 ABI (typo in gc_priv.h).
|
||
|
|
|
||
|
|
|
||
|
|
== [4.13alpha2] 1998-08-08 ==
|
||
|
|
|
||
|
|
* Fixed more Linux threads problems.
|
||
|
|
* Changed default GC_free_space_divisor to 3 with new large block allocation
|
||
|
|
(thanks to Matthew Flatt for some measurements that suggest the old
|
||
|
|
value sometimes favors space too much over time).
|
||
|
|
* More CYGWIN32 fixes.
|
||
|
|
* Integrated Tyson Dowd's Linux-M68K port.
|
||
|
|
* Minor HP PA and DEC UNIX fixes from Fergus Henderson.
|
||
|
|
* Integrated Christoffe Raffali's Linux-SPARC changes.
|
||
|
|
* Allowed for one more GC fixup iteration after a full GC in incremental
|
||
|
|
mode. Some quick measurements suggested that this significantly
|
||
|
|
reduces pause times even with smaller GC_RATE values.
|
||
|
|
* Moved some more GC data structures into GC_arrays. This decreases
|
||
|
|
pause times and GC overhead, but makes debugging slightly less convenient.
|
||
|
|
* Fixed namespace pollution problem ("excl_table").
|
||
|
|
* Made GC_incremental a constant for -DSMALL_CONFIG, hopefully shrinking
|
||
|
|
that slightly.
|
||
|
|
* Added some win32 threads fixes.
|
||
|
|
* Integrated Ivan Demakov and David Stes' Watcom fixes.
|
||
|
|
* Various other minor fixes contributed by many people.
|
||
|
|
* Renamed config.h to gcconfig.h, since config.h tends to be used for
|
||
|
|
many other things.
|
||
|
|
* Integrated Matthew Flatt's support for 68K MacOS "far globals".
|
||
|
|
* Fixed up some of the dynamic library Makefile targets for consistency
|
||
|
|
across platforms.
|
||
|
|
* Fixed a USE_MMAP typo that caused out-of-memory handling to fail
|
||
|
|
on Solaris.
|
||
|
|
* Added code to test.c to test thread creation a bit more.
|
||
|
|
* Integrated GC_win32_free_heap (as suggested by Ivan Demakov).
|
||
|
|
* Fixed Solaris 2.7 stack base finding problem. (This may actually
|
||
|
|
have been done in an earlier alpha release.)
|
||
|
|
|
||
|
|
|
||
|
|
== [4.13alpha1] 1998-02-17 ==
|
||
|
|
|
||
|
|
* Changed RS6000 STACKBOTTOM.
|
||
|
|
* Integrated Patrick Beard's Mac changes.
|
||
|
|
* Alpha1 didn't compile on Irix m.n, m < 6.
|
||
|
|
* Replaced Makefile.dj with a new one from Gary Leavens.
|
||
|
|
* Added Andrew Stitcher's changes to support SCO OpenServer.
|
||
|
|
* Added PRINT_BLACK_LIST, to allow debugging of high densities of false
|
||
|
|
pointers.
|
||
|
|
* Added code to debug allocator to keep track of return address
|
||
|
|
in GC_malloc caller, thus giving a bit more context.
|
||
|
|
* Changed default behavior of large block allocator to more
|
||
|
|
aggressively avoid fragmentation. This is likely to slow down the
|
||
|
|
collector when it succeeds at reducing space cost.
|
||
|
|
* Integrated Fergus Henderson's CYGWIN32 changes. They are untested,
|
||
|
|
but needed for newer versions.
|
||
|
|
* USE_MMAP had some serious bugs. This caused the collector to fail
|
||
|
|
consistently on Solaris with -DSMALL_CONFIG.
|
||
|
|
* Added Linux threads support (thanks to Fergus Henderson).
|
||
|
|
|
||
|
|
|
||
|
|
== [4.12] 1997-08-26 ==
|
||
|
|
|
||
|
|
* Fixed ElfW definition in dyn_load.c.
|
||
|
|
This prevented the dynamic library support from compiling on some
|
||
|
|
older ELF Linux systems.
|
||
|
|
* Fixed UTS4 port (which I apparently mangled during the integration).
|
||
|
|
(Thanks to Alistair Crooks.)
|
||
|
|
* "Make C++" failed on Suns with SC4.0, due to a problem with "bool".
|
||
|
|
Fixed in gc_priv.h.
|
||
|
|
* Added more pieces for GNU win32 (thanks to Timothy N. Newsham).
|
||
|
|
The current state of things should suffice for at least some
|
||
|
|
applications.
|
||
|
|
* Changed the out of memory retry count handling. (This matters only
|
||
|
|
if GC_max_retries > 0, which is no longer the default.)
|
||
|
|
* If a /proc read failed repeatedly, GC_written_pages was not updated
|
||
|
|
correctly (thanks to Peter Chubb for diagnosing this).
|
||
|
|
* Under unlikely circumstances, the allocator could infinite loop in
|
||
|
|
an out of memory situation (thanks to Kenjiro Taura for
|
||
|
|
identifying the problem and supplying a fix).
|
||
|
|
* Fixed a syntactic error in the DJGPP code. Also fixed a test program
|
||
|
|
problem with DJGPP (thanks to Fergus Henderson and Peter Monks).
|
||
|
|
* Atomic uncollectible objects were not treated correctly by the
|
||
|
|
incremental collector. This resulted in weird log statistics and
|
||
|
|
occasional performance problems (thanks to Peter Chubb for pointing this out).
|
||
|
|
* Fixed some problems resulting from compilers that don't define
|
||
|
|
__STDC__. In this case void * and char * were used inconsistently
|
||
|
|
in some cases. (Void * should not have been used at all. If
|
||
|
|
you have an ANSI superset compiler that does not define __STDC__,
|
||
|
|
please compile with -D__STDC__=0. Thanks to Manuel Serrano and others
|
||
|
|
for pointing out the problem.)
|
||
|
|
* Fixed a compilation problem on Irix with -n32 and -DIRIX_THREADS.
|
||
|
|
Also fixed some other IRIX_THREADS problems which may or may not have
|
||
|
|
had observable symptoms.
|
||
|
|
* Fixed an HP PA compilation problem in dyn_load.c (thanks to
|
||
|
|
Philippe Queinnec).
|
||
|
|
* SEGV fault handlers sometimes did not get reset correctly (thanks
|
||
|
|
to David Pickens).
|
||
|
|
* Added a fix for SOLARIS_THREADS on Intel (thanks to David Pickens).
|
||
|
|
This probably needs more work to become functional.
|
||
|
|
* Fixed struct sigcontext_struct in os_dep.c for compilation under
|
||
|
|
Linux 2.1.X (thanks to Fergus Henderson).
|
||
|
|
* Changed the DJGPP STACKBOTTOM and DATASTART values to those ones suggested
|
||
|
|
(by Kristian Kristensen). These may still not be right, but it is
|
||
|
|
it is likely to work more often than what was there before. They may
|
||
|
|
even be exactly right.
|
||
|
|
* Added a #include <string.h> to test_cpp.cc. This appears to help
|
||
|
|
with HP/UX and gcc (thanks to Assar Westerlund).
|
||
|
|
* Version 4.11 failed to run in incremental mode on recent 64-bit Irix
|
||
|
|
kernels. This was a problem related to page unaligned heap segments.
|
||
|
|
Changed the code to page align heap sections on all platforms.
|
||
|
|
(I had mistakenly identified this as a kernel problem earlier.
|
||
|
|
It was not.)
|
||
|
|
* Version 4.11 did not make allocated storage executable, except on
|
||
|
|
one or two platforms, due to a bug in a #if test (thanks to David Grove
|
||
|
|
for pointing this out).
|
||
|
|
* Added sparc_sunos4_mach_dep.s to support Sun's compilers under SunOS4.
|
||
|
|
* Added GC_exclude_static_roots.
|
||
|
|
* Fixed the object size mapping algorithm. This shouldn't matter,
|
||
|
|
but the old code was ugly.
|
||
|
|
* Heap checking code could die if one of the allocated objects was
|
||
|
|
larger than its base address. (Unsigned underflow problem. Thanks
|
||
|
|
to Clay Spence for isolating the problem.)
|
||
|
|
* Added RS6000 (AIX) dynamic library support and fixed STACK_BOTTOM (thanks
|
||
|
|
to Fred Stearns).
|
||
|
|
* Added Fergus Henderson's patches for improved robustness with large
|
||
|
|
heaps and lots of blacklisting.
|
||
|
|
* Added Peter Chubb's changes to support Solaris Pthreads, to support
|
||
|
|
MMAP allocation in Solaris, to allow Solaris to find dynamic libraries
|
||
|
|
through /proc, to add malloc_typed_ignore_off_page, and a few other
|
||
|
|
minor features and bug fixes.
|
||
|
|
* The Solaris 2 port should not use sbrk. I received confirmation from
|
||
|
|
Sun that the use of sbrk and malloc in the same program is not
|
||
|
|
supported. The collector now defines USE_MMAP by default on Solaris.
|
||
|
|
* Replaced the djgpp makefile with Gary Leavens' version.
|
||
|
|
* Fixed MSWIN32 detection test.
|
||
|
|
* Added Fergus Henderson's patches to allow putting the collector into
|
||
|
|
a DLL under GNU win32.
|
||
|
|
* Added Ivan V. Demakov's port to Watcom C on X86.
|
||
|
|
* Added Ian Piumarta's Linux/PowerPC port.
|
||
|
|
* Added PointerFreeGC to the placement options in gc_cpp.h (suggested by
|
||
|
|
Brian Burton). This is of course unsafe, and may be controversial.
|
||
|
|
On the other hand, it seems to be needed often enough that it's worth
|
||
|
|
adding as a standard facility.
|
||
|
|
* Add Lars Farm's suggestions on building the collector for MacOS.
|
||

|
|

|
|
== [4.11] 1996-12-03 ==
|
||
|
|
|
||
|
|
* Rationalized (hopefully) GC_try_to_collect in an incremental collection
|
||
|
|
environment. It appeared to not handle a call while a collection was in
|
||
|
|
progress, and was otherwise too conservative.
|
||
|
|
* Merged GC_reclaim_or_delete_all into GC_reclaim_all to get rid of some
|
||
|
|
code.
|
||
|
|
* Added Patrick Beard's Mac fixes, with substantial completely untested
|

|
|
modifications.
|
||
|
|
* Fixed the MPROTECT_VDB code to deal with large pages and imprecise
|
||
|
|
fault addresses (as on an UltraSPARC running Solaris 2.5). Note that this
|
||
|
|
was not a problem in the default configuration, which uses PROC_VDB.
|
||
|
|
* The DEC Alpha assembly code needed to restore $gp between calls (thanks to
|
||
|
|
Fergus Henderson for tracking this down and supplying a patch).
|
||
|
|
* The write command for "de" was completely broken for large files.
|
||
|
|
I used the easiest portable fix, which involved changing the semantics
|
||
|
|
so that f.new is written instead of overwriting f. That's safer anyway.
|
||
|
|
* Added README.solaris2 with a discussion of the possible problems of
|
||
|
|
mixing the collector's sbrk allocation with malloc/realloc.
|
||
|
|
* Changed the data segment starting address for SGI machines. The
|
||
|
|
old code failed under IRIX6.
|
||
|
|
* Required double word alignment for MIPS.
|
||
|
|
* Various minor fixes to remove warnings.
|
||
|
|
* Attempted to fix some Solaris threads problems (reported by Zhiying Chen).
|
||
|
|
In particular, the collector could try to fork a thread with the
|
||
|
|
world stopped as part of GC_thr_init. It also failed to deal with
|
||
|
|
the case in which the original thread terminated before the whole
|
||
|
|
process did.
|
||
|
|
* Added -DNO_EXECUTE_PERMISSION. This has a major performance impact
|
||
|
|
on the incremental collector under Irix, and perhaps under other
|
||
|
|
operating systems.
|
||
|
|
* Added some code to support allocating the heap with mmap. This may
|
||
|
|
be preferable under some circumstances.
|
||
|
|
* Integrated dynamic library support for HP (thanks to Knut Tvedten).
|
||
|
|
* Integrated James Clark's win32 threads support, and made a number
|
||
|
|
of changes to it (many of which suggested by Pontus Rydin). This is still
|
||
|
|
not 100% solid.
|
||
|
|
* Integrated Alistair G. Crooks' support for UTS4 running on an Amdahl
|
||
|
|
370-class machine.
|
||
|
|
* Fixed a serious bug in explicitly typed allocation. Objects requiring
|
||
|
|
large descriptors where handled in a way that usually resulted in
|
||
|
|
a segmentation fault in the marker (thanks to Jeremy Fitzhardinge
|
||
|
|
for helping to track this down).
|
||
|
|
* Added partial support for GNU win32 development (thanks to
|
||
|
|
Fergus Henderson).
|
||
|
|
* Added optional support for Java-style finalization semantics (thanks to
|
||
|
|
Patrick Bridges). This is recommended only for Java implementations.
|
||
|
|
* GC_malloc_uncollectable faulted instead of returning 0 when out of
|
||
|
|
memory (thanks to Daniel R. Grayson for noticing).
|
||
|
|
* Calls to GC_base before the collector was initialized failed on a
|
||
|
|
DEC Alpha (thanks to Matthew Flatt).
|
||
|
|
* Added base pointer checking to GC_REGISTER_FINALIZER in debugging mode
|
||
|
|
(thanks to Jeremy Fitzhardinge).
|
||
|
|
* GC_debug_realloc failed for uncollectible objects (thanks to
|
||
|
|
Jeremy Fitzhardinge).
|
||
|
|
* Explicitly typed allocation could crash if it ran out of memory (thanks to
|
||
|
|
Jeremy Fitzhardinge).
|
||
|
|
* Added minimal support for a DEC Alpha running Linux.
|
||
|
|
* Fixed a problem with allocation of objects whose size overflowed
|
||
|
|
ptrdiff_t. (This now fails unconditionally, as it should.)
|
||
|
|
* Added the beginning of Irix pthread support.
|
||
|
|
* Integrated Xiaokun Zhu's fixes for djgpp 2.01.
|
||
|
|
* Added SGI-style STL allocator support (gc_alloc.h).
|
||
|
|
* Fixed a serious bug in README.solaris2.
|
||
|
|
Multi-threaded programs must include
|
||
|
|
gc.h with SOLARIS_THREADS defined.
|
||
|
|
* Changed GC_free so it actually deallocates uncollectible objects (thanks
|
||
|
|
to Peter Chubb for pointing out the problem).
|
||
|
|
* Added Linux ELF support for dynamic libraries (thanks to Patrick Bridges).
|
||
|
|
* Changed the Borland cc configuration so that the assembler is not
|
||
|
|
required.
|
||
|
|
* Fixed a bug in the C++ test that caused it to fail in 64-bit
|
||
|
|
environments.

|
== [4.10t3] 1996-11-18 ==
|
||
|
|
|
||
|
|
Some changes related to threads support.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.10] 1996-02-19 ==
|
||
|
|
|
||
|
|
* Fixed a typo around a call to GC_collect_or_expand in alloc.c. It broke
|
||
|
|
handling of out of memory. (Thanks to Patrick C. Beard for noticing.)
|
||
|
|
|
||
|
|
|
||
|
|
== [4.9] 1996-02-12 ==
|
||
|
|
|
||
|
|
* More README.debugging fixes.
|
||
|
|
* Objects ready for finalization, but not finalized in the same GC
|
||
|
|
cycle, could be prematurely collected. This occasionally happened
|
||
|
|
in test_cpp.
|
||
|
|
* Too little memory was obtained from the system for very large
|
||
|
|
objects. That could cause a heap explosion if these objects were
|
||
|
|
not contiguous (e.g. under PCR), and too much of them was blacklisted.
|
||
|
|
* Due to an improper initialization, the collector was too hesitant to
|
||
|
|
allocate blacklisted objects immediately after system startup.
|
||
|
|
* Moved GC_arrays from the data into the bss segment by not explicitly
|
||
|
|
initializing it to zero. This significantly
|
||
|
|
reduces the size of executables, and probably avoids some disk accesses
|
||
|
|
on program startup. It's conceivable that it might break a port that I
|
||
|
|
didn't test.
|
||
|
|
* Fixed EMX_MAKEFILE to reflect the gc_c++.h to gc_cpp.h renaming which
|
||
|
|
occurred a while ago.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.8] 1995-11-20 ==
|
||
|
|
|
||
|
|
* Changed a "comment" in a MacOS specific part of mach_dep.c that caused
|
||
|
|
gcc to fail on other platforms.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.7] 1995-11-18 ==
|
||
|
|
|
||
|
|
* Fixed some compilation problems with -DCHECKSUMS (thanks to Ian Searle).
|
||
|
|
* Updated some Mac specific files (to synchronize with Patrick C. Beard).
|
||
|
|
* Fixed a serious bug for machines with non-word-aligned pointers.
|
||
|
|
(Thanks to Patrick C. Beard for pointing out the problem. The collector
|
||
|
|
should fail almost any conceivable test immediately on such machines.)
|
||
|
|
|
||
|
|
|
||
|
|
== [4.6] 1995-11-09 ==
|
||
|
|
|
||
|
|
* Added Linux ELF support (thanks to Arrigo Triulzi).
|
||
|
|
* GC_base crashed if it was called before any other GC_ routines.
|
||
|
|
This could happen if a gc_cleanup object was allocated outside the heap
|
||
|
|
before any heap allocation.
|
||
|
|
* The heap expansion heuristic was not stable if all objects had finalization
|
||
|
|
enabled. Fixed finalize.c to count memory in finalization queue and
|
||
|
|
avoid explicit deallocation. Changed alloc.c to also consider this count.
|
||
|
|
(This is still not recommended. It's expensive if nothing else. Thanks
|
||
|
|
to John Ellis for pointing this out.)
|
||
|
|
* GC_malloc_uncollectable(0) was broken (thanks to Phong Vo for pointing
|
||
|
|
this out).
|
||
|
|
* The collector didn't compile under Linux 1.3.X (thanks to Fred Gilham for
|
||
|
|
pointing this out). The current workaround is ugly, but expected to be
|
||
|
|
temporary.
|
||
|
|
* Fixed a formatting problem for SPARC stack traces.
|
||
|
|
* Fixed some '=='s in os_dep.c that should have been assignments.
|
||
|
|
Fortunately these were in code that should never be executed anyway (thanks
|
||
|
|
to Fergus Henderson).
|
||
|
|
* Fixed the heap block allocator to only drop blacklisted blocks in small
|
||
|
|
chunks. Made BL_LIMIT self adjusting. (Both of these were in response
|
||
|
|
to heap growth observed by Paul Graham.)
|
||
|
|
* Fixed the Metrowerks/68K Mac code to also mark from a6 (thanks to
|
||
|
|
Patrick C. Beard).
|
||
|
|
* Significantly updated README.debugging.
|
||
|
|
* Fixed some problems with longjmps out of signal handlers, especially under
|
||
|
|
Solaris. Added a workaround for the fact that siglongjmp doesn't appear to
|
||
|
|
do the right thing with -lthread under Solaris.
|
||
|
|
* Added MSDOS/djgpp port (thanks to Mitch Harris).
|
||
|
|
* Added "make reserved_namespace" and "make user_namespace". The
|
||
|
|
first renames ALL "GC_xxx" identifiers as "_GC_xxx". The second is the
|
||
|
|
inverse transformation. Note that doing this is guaranteed to break all
|
||
|
|
clients written for the other names.
|
||
|
|
* descriptor field for kind NORMAL in GC_obj_kinds with ADD_BYTE_AT_END
|
||
|
|
defined should be -ALIGNMENT not WORDS_TO_BYTES(-1). This is
|
||
|
|
a serious bug on machines with pointer alignment of less than a word.
|
||
|
|
* GC_ignore_self_finalize_mark_proc didn't handle pointers to very near the
|
||
|
|
end of the object correctly. Caused failures of the C++ test on a DEC Alpha
|
||
|
|
with g++.
|
||
|
|
* gc_inl.h still had problems. Partially fixed. Added warnings at the
|
||
|
|
beginning to hopefully specify the remaining dangers.
|
||
|
|
* Added DATAEND definition to config.h.
|
||
|
|
* Fixed some of the .h file organization. Fixed "make floppy".
|
||
|
|
|
||
|
|
|
||
|
|
== [4.5] 1995-06-14 ==
|
||
|
|
|
||
|
|
* Fixed many minor and one major README bugs (thanks to Franklin Chen
|
||
|
|
for pointing out many of them).
|
||
|
|
* Fixed ALPHA/OSF/1 dynamic library support (thanks to Jonathan Bachrach).
|
||
|
|
* Added incremental GC support (MPROTECT_VDB) for Linux (with some
|
||
|
|
help from Bruno Haible).
|
||
|
|
* Altered SPARC recognition tests in gc.h and config.h (mostly as
|
||
|
|
suggested by Fergus Henderson).
|
||
|
|
* Added basic incremental GC support for win32, as implemented by
|
||
|
|
Windows NT and Windows 95. GC_enable_incremental is a no-op
|
||
|
|
under win32s, which doesn't implement enough of the VM interface.
|
||
|
|
* Added -DLARGE_CONFIG.
|
||
|
|
* Fixed GC_..._ignore_off_page to also function without
|
||
|
|
-DALL_INTERIOR_POINTERS.
|
||
|
|
* (Hopefully) fixed RS/6000 port. (Only the test was broken.)
|
||
|
|
* Fixed a performance bug in the non-incremental collector running
|
||
|
|
on machines supporting incremental collection with MPROTECT_VDB
|
||
|
|
(e.g. SunOS 4, DEC AXP). This turned into a correctness bug under
|
||
|
|
win32s with win32 incremental collection. (Not all memory protection
|
||
|
|
was disabled.)
|
||
|
|
* Fixed some ppcr related bit rot.
|
||
|
|
* Caused dynamic libraries to be unregistered before re-registering.
|
||
|
|
The old way turned out to be a performance bug on some machines.
|
||
|
|
* GC_root_size was not properly maintained under MSWIN32.
|
||
|
|
* Added -DNO_DEBUGGING and GC_dump.
|
||
|
|
* Fixed a couple of bugs arising with SOLARIS_THREADS +
|
||
|
|
REDIRECT_MALLOC.
|
||
|
|
* Added NetBSD/M68K port (thanks to Peter Seebach).
|
||
|
|
* Fixed a serious realloc bug. For certain object sizes, the collector
|
||
|
|
wouldn't scan the expanded part of the object. (Thanks to Clay Spence
|
||
|
|
for noticing the problem, and helping me to track it down.)
|
||
|
|
|
||
|
|
|
||
|
|
== [4.4] 1995-02-18 ==
|
||
|
|
|
||
|
|
* ASM_CLEAR_CODE was erroneously defined for HP
|
||
|
|
PA machines, resulting in a compile error.
|
||
|
|
* Fixed OS/2 Makefile to create a library (thanks to Mark Boulter).
|
||
|
|
* Gc_cleanup objects didn't work if they were created on
|
||
|
|
the stack. Fixed.
|
||
|
|
* One copy of Gc_cpp.h in the distribution was out of
|
||
|
|
synch, and failed to document some known compiler
|
||
|
|
problems with explicit destructor invocation. Partially
|
||
|
|
fixed. There are probably other compilers on which
|
||
|
|
gc_cleanup is miscompiled.
|
||
|
|
* Fixed Makefile to pass C compiler flags to C++ compiler.
|
||
|
|
* Added Mac fixes.
|
||
|
|
* Fixed os_dep.c to work around what appears to be
|
||
|
|
a new and different VirtualQuery bug under newer
|
||
|
|
versions of win32S.
|
||
|
|
* GC_non_gc_bytes was not correctly maintained by
|
||
|
|
GC_free. Fixed (thanks to James Clark).
|
||
|
|
* Added GC_set_max_heap_size.
|
||
|
|
* Changed allocation code to ignore blacklisting if it is preventing
|
||
|
|
use of a very large block of memory. This has the advantage
|
||
|
|
that naive code allocating very large objects is much more
|
||
|
|
likely to work. The downside is you might no
|
||
|
|
longer find out that such code should really use
|
||
|
|
GC_malloc_ignore_off_page.
|
||
|
|
* Changed GC_printf under win32 to close and reopen the file
|
||
|
|
between calls. FAT file systems otherwise make the log file
|
||
|
|
useless for debugging.
|
||
|
|
* Added GC_try_to_collect and GC_get_bytes_since_gc. These
|
||
|
|
allow starting an abortable collection during idle times.
|
||
|
|
This facility does not require special OS support. (Thanks to
|
||
|
|
Michael Spertus of Geodesic Systems for suggesting this. It was
|
||
|
|
actually an easy addition. Kumar Srikantan previously added a similar
|
||
|
|
facility to a now ancient version of the collector. At the time
|
||
|
|
this was much harder, and the result was less convincing.)
|
||
|
|
* Added some support for the Borland development environment (thanks
|
||
|
|
to John Ellis and Michael Spertus).
|
||
|
|
* Removed a misfeature from checksums.c that caused unexpected
|
||
|
|
heap growth (thanks to Scott Schwartz).
|
||
|
|
* Changed finalize.c to call WARN if it encounters a finalization cycle.
|
||
|
|
WARN is defined in gc_priv.h to write a message, usually to stdout.
|
||
|
|
In many environments, this may be inappropriate.
|
||
|
|
* Renamed NO_PARAMS in gc.h to GC_NO_PARAMS, thus adhering to my own
|
||
|
|
naming convention.
|
||
|
|
* Added GC_set_warn_proc to intercept warnings.
|
||
|
|
* Fixed Amiga port (thanks to Michel Schinz).
|
||
|
|
* Fixed a bug in mark.c that could result in an access to unmapped
|
||
|
|
memory from GC_mark_from_mark_stack on machines with unaligned
|
||
|
|
pointers.
|
||
|
|
* Fixed a win32 specific performance bug that could result in scanning of
|
||
|
|
objects allocated with the system malloc.
|
||
|
|
* Added REDIRECT_MALLOC.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.3] 1994-12-23 ==
|
||
|
|
|
||
|
|
* Fixed SPARC alignment problem with GC_DEBUG.
|
||
|
|
* Fixed Solaris threads /proc workaround. The real
|
||
|
|
problem was an interaction with mprotect.
|
||
|
|
* Incorporated fix from Patrick Beard for gc_c++.h (now gc_cpp.h).
|
||
|
|
* Slightly improved allocator space utilization by
|
||
|
|
fixing the GC_size_map mechanism.
|
||
|
|
* Integrated some Sony News and MIPS RISCos 4.51
|
||
|
|
patches (thanks to Nobuyuki Hikichi at Software Research Associates,
|
||
|
|
Inc., Japan).
|
||
|
|
* Fixed HP_PA alignment problem (thanks to Brian F. Dennis).
|
||
|
|
* Added GC_same_obj and friends. Changed GC_base
|
||
|
|
to return 0 for pointers past the end of large objects.
|
||
|
|
Improved GC_base performance with ALL_INTERIOR_POINTERS
|
||
|
|
on machines with a slow integer mod operation.
|
||
|
|
Added GC_PTR_ADD, GC_PTR_STORE, etc. to prepare
|
||
|
|
for preprocessor.
|
||
|
|
* changed the default on most UNIX machines to be that
|
||
|
|
signals are not disabled during critical GC operations.
|
||
|
|
This is still ANSI-conforming, though somewhat dangerous
|
||
|
|
in the presence of signal handlers. But the performance
|
||
|
|
cost of the alternative is sometimes problematic.
|
||
|
|
Can be changed back with a minor Makefile edit.
|
||
|
|
* renamed IS_STRING in gc.h, to CORD_IS_STRING, thus
|
||
|
|
following my own naming convention. Added the function
|
||
|
|
CORD_to_const_char_star.
|
||
|
|
* Fixed a gross bug in GC_finalize. Symptom: occasional
|
||
|
|
address faults in that function (thanks to Anselm Baird-Smith).
|
||
|
|
* Added port to ICL DRS6000 running DRS/NX. Restructured
|
||
|
|
things a bit to factor out common code, and remove obsolete
|
||
|
|
code. Collector should now run under SUNOS5 with either
|
||
|
|
mprotect or /proc dirty bits. (Thanks to Douglas Steel.)
|
||
|
|
* More bug fixes and workarounds for Solaris 2.X. (These were
|
||
|
|
mostly related to putting the collector in a dynamic library,
|
||
|
|
which didn't really work before. Also SOLARIS_THREADS
|
||
|
|
didn't interact well with dl_open.) (Thanks to Brian Lewis.)
|
||
|
|
* Fixed a serious performance bug on the DEC Alpha. The text
|
||
|
|
segment was getting registered as part of the root set.
|
||
|
|
(Amazingly, the result was still fast enough that the bug
|
||
|
|
was not conspicuous.) The fix works on OSF/1, version 1.3.
|
||
|
|
Hopefully it also works on other versions of OSF/1 ...
|
||
|
|
* Fixed a bug in GC_clear_roots.
|
||
|
|
* Fixed a bug in GC_generic_malloc_words_small that broke
|
||
|
|
gc_inl.h (reported by Antoine de Maricourt).
|
||
|
|
* Fixed some problems with cord/de under Linux.
|
||
|
|
* Fixed some cord problems, notably with CORD_riter4.
|
||
|
|
* Added DG/UX port (thanks to Ben A. Mesander).
|
||
|
|
* Added finalization registration routines with weaker ordering
|
||
|
|
constraints. (This is necessary for C++ finalization with
|
||
|
|
multiple inheritance, since the compiler often adds self-cycles.)
|
||
|
|
* Filled the holes in the SCO port (thanks to Michael Arnoldus).
|
||
|
|
* Completely rewritten the documentation in the interface gc_c++.h
|
||
|
|
(later renamed gc_cpp.h) making it both clearer and more precise (done by
|
||
|
|
John Ellis).
|
||
|
|
* The definition of accessibility now ignores pointers from a finalizable
|
||
|
|
object (an object with a clean-up function) to itself (done by John Ellis).
|
||
|
|
This allows objects with virtual base classes to be finalizable by the
|
||
|
|
collector. Compilers typically implement virtual base classes using
|
||
|
|
pointers from an object to itself, which under the old definition of
|
||
|
|
accessibility prevented objects with virtual base classes from ever
|
||
|
|
being collected or finalized.
|
||
|
|
* gc_cleanup now includes gc as a virtual base. This was enabled by
|
||
|
|
the change in the definition of accessibility (by John Ellis).
|
||
|
|
* Added support for operator new[] (by John Ellis). Since most compilers
|
||
|
|
don't yet support operator new[], it is conditionalized on
|
||
|
|
-DOPERATOR_NEW_ARRAY. The code is untested, but its trivial and looks
|
||
|
|
correct.
|
||
|
|
* The test program test_gc_c++ (later renamed test_cpp.cc)
|
||
|
|
tries to test for the C++-specific functionality not tested by the
|
||
|
|
other programs.
|
||
|
|
* Added unistd.h include to misc.c. (Needed for ppcr.)
|
||
|
|
* Added PowerMac port (thanks to Patrick C. Beard).
|
||
|
|
* Fixed "srcdir"-related Makefile problems. Changed things so
|
||
|
|
that all externally visible include files always appear in the
|
||
|
|
include subdirectory of the source. Made gc.h directly
|
||
|
|
includable from C++ code (thanks to Per Bothner).
|
||
|
|
* Changed Intel code to also mark from ebp (thanks to Kevin Warne).
|
||
|
|
* Renamed C++ related files so they could live in a FAT
|
||
|
|
file system (thanks to Charles Fiterman).
|
||
|
|
* Changed Windows NT Makefile to include C++ support in
|
||
|
|
gc.lib. Added C++ test as Makefile target.

== [4.2] 1994-08-03 ==
|
||
|
|
|
||
|
|
* Multiple bug fixes/workarounds in the Solaris threads version.
|
||
|
|
(It occasionally failed to locate some register contents for
|
||
|
|
marking. It also turns out that thr_suspend and friends are
|
||
|
|
unreliable in Solaris 2.3. Dirty bit reads appear
|
||
|
|
to be unreliable under some weird
|
||
|
|
circumstances. My stack marking code
|
||
|
|
contained a serious performance bug. The new code is
|
||
|
|
extremely defensive, and has not failed in several CPU
|
||
|
|
hours of testing. But no guarantees ...)
|
||
|
|
* Added MacOS support. (Thanks to Patrick C. Beard.
|
||
|
|
David Chase suggested several improvements.)
|
||
|
|
* Fixed several syntactic bugs in gc_c++.h and friends. (These
|
||
|
|
didn't bother g++, but did bother most other compilers.)
|
||
|
|
Fixed gc_c++.h finalization interface.
|
||
|
|
* 64 bit alignment for allocated objects was not guaranteed in a
|
||
|
|
few cases in which it should have been.
|
||
|
|
* Added GC_malloc_atomic_ignore_off_page.
|
||
|
|
* Added GC_collect_a_little.
|
||
|
|
* Added some prototypes to gc.h.
|
||
|
|
* Some other minor bug fixes (notably in Makefile).
|
||
|
|
* Fixed OS/2 / EMX port (thanks to Ari Huttunen).
|
||
|
|
* Fixed AmigaDOS port (thanks to Michel Schinz).
|
||
|
|
* Fixed the DATASTART definition under Solaris. There
|
||
|
|
was a 1 in 16K chance of the collector missing the first
|
||
|
|
64K of static data (and thus crashing).
|
||
|
|
* Fixed some blatant anachronisms in the README file.
|
||
|
|
* Fixed PCR-Makefile for upcoming PPCR release.
|
||
|
|
|
||
|
|
|
||
|
|
== [4.1] 1994-05-20 ==
|
||
|
|
|
||
|
|
* Changed finalization implementation to guarantee that
|
||
|
|
finalization procedures are called outside of the allocation
|
||
|
|
lock, making direct use of the interface a little less dangerous.
|
||
|
|
MAY BREAK EXISTING CLIENTS that assume finalizers
|
||
|
|
are protected by a lock. Since there seem to be few multi-threaded
|
||
|
|
clients that use finalization, this is hopefully not much of
|
||
|
|
a problem.
|
||
|
|
* Fixed a gross bug in CORD_prev.
|
||
|
|
* Fixed a bug in blacklst.c that could result in unbounded
|
||
|
|
heap growth during startup on machines that do not clear
|
||
|
|
memory obtained from the OS (e.g. win32S).
|
||
|
|
* Ported de editor to win32/win32S. (This is now the only
|
||
|
|
version with a mouse-sensitive UI. Thanks to Rob Haack for the
|
||
|
|
implementation based on the generic Windows application template.)
|
||
|
|
* Added GC_malloc_ignore_off_page to allocate large arrays
|
||
|
|
in the presence of ALL_INTERIOR_POINTERS.
|
||
|
|
* Changed GC_call_with_alloc_lock to not disable signals in
|
||
|
|
the single-threaded case.
|
||
|
|
* Reduced retry count in GC_collect_or_expand for garbage
|
||
|
|
collecting when out of memory.
|
||
|
|
* Made uncollectible allocations bypass black-listing, as they
|
||
|
|
should.
|
||
|
|
* Fixed a bug in typed_test in test.c that could cause (legitimate)
|
||
|
|
GC crashes.
|
||
|
|
* Fixed some potential synchronization problems in finalize.c
|
||
|
|
* Fixed a real locking problem in typd_mlc.c.
|
||
|
|
* Worked around an AIX 3.2 compiler feature that results in
|
||
|
|
out of bounds memory references.
|
||
|
|
* Partially worked around an IRIX5.2 beta problem (which may
|
||
|
|
or may not persist to the final release).
|
||
|
|
* Fixed a bug in the heap integrity checking code that could
|
||
|
|
result in explicitly deallocated objects being identified as
|
||
|
|
smashed. Fixed a bug in the dbg_mlc stack saving code
|
||
|
|
that caused old argument pointers to be considered live.
|
||
|
|
* Fixed a bug in CORD_ncmp (and hence CORD_str).
|
||
|
|
* Repaired the OS2 port, which had suffered from bit rot
|
||
|
|
in 4.0. Worked around what appears to be CSet/2 V1.0
|
||
|
|
optimizer bug.
|
||
|
|
* Fixed a Makefile bug for target "c++".
|
||
|
|
|
||
|
|
|
||
|
|
== [4.0] 1994-04-07 ==
|
||
|
|
|
||
|
|
* Added support for Solaris threads (which was possible
|
||
|
|
only by reimplementing some fraction of Solaris threads,
|
||
|
|
since Sun doesn't currently make the thread debugging
|
||
|
|
interface available).
|
||
|
|
* Added non-threads win32 and win32S support.
|
||
|
|
* (Grudgingly, with suitable muttering of obscenities) renamed
|
||
|
|
files so that the collector distribution could live on a FAT
|
||
|
|
file system. Files that are guaranteed to be useless on
|
||
|
|
a PC still have long names. Gc_inline.h and gc_private.h
|
||
|
|
still exist, but now just include gc_inl.h and gc_priv.h.
|
||
|
|
* Fixed a really obscure bug in finalization that could cause
|
||
|
|
undetected mark stack overflows. (I would be surprised if
|
||
|
|
any real code ever tickled this one.)
|
||
|
|
* Changed finalization code to dynamically resize the hash
|
||
|
|
tables it maintains. (This probably does not matter for well-
|
||
|
|
-written code. It no doubt does for C++ code that overuses
|
||
|
|
destructors.)
|
||
|
|
* Added typed allocation primitives. Rewrote the marker to
|
||
|
|
accommodate them with more reasonable efficiency. This
|
||
|
|
change should also speed up marking for GC_malloc allocated
|
||
|
|
objects a little. See gc_typed.h for new primitives. (Thanks to
|
||
|
|
Zhong Shao performed much of the experimentation that led to the
|
||
|
|
current typed allocation facility.)
|
||
|
|
* Improved debugging facilities slightly. Allocation time
|
||
|
|
stack traces are now kept by default on SPARC/SUNOS4. (Thanks to
|
||
|
|
Scott Schwartz.)
|
||
|
|
* Added better support for small heap applications.
|
||
|
|
* Significantly extended cord package. Fixed a bug in the
|
||
|
|
implementation of lazily read files. Printf and friends now
|
||
|
|
have cord variants. Cord traversals are a bit faster.
|
||
|
|
* Made ALL_INTERIOR_POINTERS recognition the default.
|
||
|
|
* Fixed de so that it can run in constant space, independent
|
||
|
|
of file size. Added simple string searching to cords and de.
|
||
|
|
* Added the Hull-Ellis C++ interface (supplied by Jesse Hull and John Ellis).
|
||
|
|
* Added dynamic library support for OSF/1 (thanks to Alan Dosser and
|
||
|
|
Tim Bingham at DEC).
|
||
|
|
* Changed argument to GC_expand_hp to be expressed
|
||
|
|
in units of bytes instead of heap blocks. (Necessary
|
||
|
|
since the heap block size now varies depending on
|
||
|
|
configuration. The old version was never very clean.)
|
||
|
|
* Added GC_get_heap_size(). The previous "equivalent"
|
||
|
|
was broken.
|
||
|
|
* Restructured the Makefile a bit.
|
||
|
|
* Added FreeBSD port (provided by Jeffrey Hsu).
|
||
|
|
|
||
|
|
|
||
|
|
== [3.7] 1994-03-15 ==
|
||
|
|
|
||
|
|
* Added a workaround for an HP/UX compiler bug.
|
||
|
|
* Fixed another stack clearing performance bug. Reworked
|
||
|
|
that code once more.
|
||
|
|
|
||
|
|
|
||
|
|
== [3.6] 1994-01-14 ==
|
||
|
|
|
||
|
|
* fixed a bug in the mark stack growth code that was introduced
|
||
|
|
in 3.4.
|
||
|
|
* fixed Makefile to work around DEC AXP compiler tail recursion
|
||
|
|
bug.
|
||
|
|
|
||
|
|
|
||
|
|
== [3.5] ==
|
||
|
|
|
||
|
|
* Minor collections now mark from roots only once, if that
|
||
|
|
doesn't cause an excessive pause.
|
||
|
|
* The stack clearing heuristic was refined to prevent anomalies
|
||
|
|
with very heavily recursive programs and sparse stacks.
|
||
|
|
* Fixed a bug that prevented mark stack growth in some cases.
|
||
|
|
GC_objects_are_marked should be set to TRUE after a call
|
||
|
|
to GC_push_roots and as part of GC_push_marked, since
|
||
|
|
both can now set mark bits. I think this is only a performance
|
||
|
|
bug, but I wouldn't bet on it. It's certainly very hard to argue
|
||
|
|
that the old version was correct.
|
||
|
|
* Fixed an incremental collection bug that prevented it from
|
||
|
|
working at all when HBLKSIZE != getpagesize()
|
||
|
|
* Changed dynamic_loading.c to include gc_priv.h before testing
|
||
|
|
DYNAMIC_LOADING. SunOS dynamic library scanning
|
||
|
|
must have been broken in 3.4.
|
||
|
|
* Object size rounding now adapts to program behavior.
|
||
|
|
* Added a workaround (provided by Manuel Serrano and
|
||
|
|
colleagues) to a long-standing SunOS 4.X (and 3.X) ld bug
|
||
|
|
that I had incorrectly assumed to have been squished.
|
||
|
|
The collector was broken if the text segment size was within
|
||
|
|
32 bytes of a multiple of 8K bytes, and if the beginning of
|
||
|
|
the data segment contained interesting roots. The workaround
|
||
|
|
assumes a demand-loadable executable. The original may have
|
||
|
|
have "worked" in some other cases.
|
||
|
|
* Added dynamic library support under IRIX5.
|
||
|
|
* Added support for EMX under OS/2 (thanks to Ari Huttunen).
|
||
|
|
* Added support of Motorola 88K processor running CX/UX (by Brent Benson).
|
||
|
|
|
||
|
|
|
||
|
|
== [3.4] ==
|
||
|
|
|
||
|
|
* Fixed a performance bug in GC_realloc.
|
||
|
|
* Updated the amiga port.
|
||
|
|
* Added NetBSD and 386BSD ports (supplied by Alistair G. Crooks).
|
||
|
|
* Added cord library.
|
||
|
|
* Added trivial performance enhancement for
|
||
|
|
ALL_INTERIOR_POINTERS (do not scan last word).
|
||
|
|
|
||
|
|
|
||
|
|
== [3.3] 1993-10-02 ==
|
||
|
|
|
||
|
|
* PCR-specific bugs (thanks to Neil Sharman).
|
||
|
|
* Missing locking in GC_free, redundant FASTUNLOCK
|
||
|
|
in GC_malloc_stubborn, and 2 bugs in
|
||
|
|
GC_unregister_disappearing_link (pointed out by Neil Sharman).
|
||
|
|
* Common symbols allocated by the SunOS4.X dynamic loader
|
||
|
|
were not included in the root set.
|
||
|
|
* Bug in GC_finalize (reported by Brian Beuning and Alan Dosser).
|
||
|
|
* Merged Amiga port from Jesper Peterson (untested).
|
||
|
|
* Merged NeXT port from Thomas Funke (significantly
|
||
|
|
modified and untested). (Also thanks to Brian D. Carlstrom for
|
||
|
|
the supplied the NeXT ports.)
|
||
|
|
|
||
|
|
|
||
|
|
== [3.2] ==
|
||
|
|
|
||
|
|
Fixed a serious and not entirely repeatable bug in
|
||
|
|
the incremental collector. It appeared only when dirty bit info
|
||
|
|
on the roots was available, which is normally only under Solaris.
|
||
|
|
It also added GC_general_register_disappearing_link, and some
|
||
|
|
testing code. Interface.c disappeared.
|
||
|
|
|
||
|
|
|
||
|
|
== [3.1] ==
|
||
|
|
|
||
|
|
* A workaround for a SunOS 4.X SPARC C compiler
|
||
|
|
misfeature that caused problems when the collector was turned into
|
||
|
|
a dynamic library.
|
||
|
|
* A fix for a bug in GC_base that could result in a memory fault.
|
||
|
|
* A fix for a performance bug (and several other misfeatures) pointed
|
||
|
|
out by Dave Detlefs and Alan Dosser.
|
||
|
|
* Use of dirty bit information for static data under Solaris 2.X.
|
||
|
|
* DEC Alpha/OSF1 support (thanks to Alan Dosser).
|
||
|
|
* Incremental collection on more platforms.
|
||
|
|
* A more refined heap expansion policy. Less space usage by default.
|
||
|
|
* Various minor enhancements to reduce space usage, and to reduce
|
||
|
|
the amount of memory scanned by the collector.
|
||
|
|
* Uncollectible allocation without per object overhead.
|
||
|
|
* More conscientious handling of out-of-memory conditions.
|
||
|
|
* Fixed a bug in debugging stubborn allocation.
|
||
|
|
* Fixed a bug that resulted in occasional erroneous reporting of smashed
|
||
|
|
objects with debugging allocation.
|
||
|
|
* Fixed bogus leak reports of size 4096 blocks with FIND_LEAK.

|
|
|

|
== [3.0] ==
|
||
|
|
|
||
|

Added generational/incremental collection and stubborn objects.

|
|
== [2.6] 1993-04-27 ==
|

(Changes not specified.)

|
|
|
||
|
|
|
||
|
|
== [2.5] ==
|
||
|
|
|
||
|
|
* Removed an explicit call to exit(1)
|
||
|
|
* Fixed calls to GC_printf and GC_err_printf, so the correct number of
|
||
|
|
arguments are always supplied. The OS/2 C compiler gets confused if
|
||
|
|
the number of actuals and the number of formals differ. (ANSI C
|
||
|
|
doesn't require this to work. The ANSI sanctioned way of doing things
|
||
|
|
causes too many compatibility problems.)
|
||
|
|
|
||
|
|
|
||
|
|
== [2.4] 1993-01-26 ==
|
||
|
|
|
||
|
|
Added GC_free_space_divisor as a tuning knob, added
|
||
|
|
support for OS/2 and linux, and fixed the following bugs:
|
||
|
|
* On machines with unaligned pointers (e.g. Sun 3), every 128th word could
|
||
|
|
fail to be considered for marking.
|
||
|
|
* Dynamic_load.c erroneously added 4 bytes to the length of the data and
|
||
|
|
bss sections of the dynamic library. This could result in a bad memory
|
||
|
|
reference if the actual length was a multiple of a page. (Observed on
|
||
|
|
Sun 3. Can probably also happen on a Sun 4.)
|
||
|
|
(Thanks to Robert Brazile for pointing out that the Sun 3 version
|
||
|
|
was broken. Dynamic library handling is still broken on Sun 3s
|
||
|
|
under 4.1.1U1, but apparently not 4.1.1. If you have such a machine,
|
||
|
|
use -Bstatic.)
|
||
|
|
|
||
|
|
|
||
|
|
== [2.3] ==
|
||
|
|
|
||
|
|
* Added ALL_INTERIOR_POINTERS.
|
||
|
|
* Missing declaration of etext in the A/UX version.
|
||
|
|
* Some PCR root-finding problems.
|
||
|
|
* Blacklisting was not 100% effective, because the plausible future
|
||
|
|
heap bounds were being miscalculated.
|
||
|
|
* GC_realloc didn't handle out-of-memory correctly.
|
||
|
|
* GC_base could return a nonzero value for addresses inside free blocks.
|
||
|
|
* test.c wasn't really thread safe, and could erroneously report failure
|
||
|
|
in a multi-threaded environment. (The locking primitives need to be
|
||
|
|
replaced for other threads packages.)
|
||
|
|
* GC_CONS was thoroughly broken.
|
||
|
|
* On a SPARC with dynamic linking, signals stayed disabled while the
|
||
|
|
client code was running (thanks to Manuel Serrano).
|
||
|
|
|
||
|
|
|
||
|
|
== [2.2] ==
|
||
|
|
|
||
|
|
* GC_realloc could fail to extend the size of the object for certain large
|
||
|
|
object sizes.
|
||
|
|
* A blatant subscript range error in GC_printf, which unfortunately
|
||
|
|
wasn't exercised on machines with sufficient stack alignment constraints.
|
||
|
|
* GC_register_displacement did the wrong thing if it was called after
|
||
|
|
any allocation had taken place.
|
||
|
|
* The leak finding code would eventually break after 2048 byte
|
||
|
|
byte objects leaked.
|
||
|
|
* interface.c didn't compile.
|
||
|
|
* The heap size remained much too small for large stacks.
|
||
|
|
* The stack clearing code behaved badly for large stacks, and perhaps
|
||
|
|
on HP/PA machines.
|

|
|
|
||
|
|
|
||
|
|
== [2.1] ==
|
||
|
|
|

|
|
* The first stable version since 1.9.
|
||
|
|
* Added support for PPCR.

|
|
|
||
|
|
|
||
|
|
== [2.0] ==
|
||
|
|
|
||
|
|
* Introduced a consistent naming convention for collector
|
||
|
|
routines and added support for registering dynamic library data segments
|
||
|
|
in the standard mark_roots.c (original code supporting the SunOS dynamic
|
||
|
|
loader provided by Bill Janssen). Most of the data structures were revamped.
|
||
|
|
The treatment of interior pointers was completely changed. Finalization
|
||
|
|
was added. Support for locking was added. Object kinds were added.
|
||
|
|
We added a black listing facility to avoid allocating at addresses known
|
||
|
|
to occur as integers somewhere in the address space. Much of this
|
||
|
|
was accomplished by adapting ideas and code from the PCR collector.
|
||
|
|
The test program was changed and expanded.
|
||
|
|

|
|
|
||
|
|
== [1.9] 1992-01-29 ==
|
||
|
|

|
|
||
|
|
|
||
|
|
== [1.8] ==
|
||
|
|
|
||
|
|
* added ULTRIX support in gc_private.h. (Robert Brazile originally supplied
|
||
|
|
the ULTRIX code. Alan Dosser and Regis Cridlig subsequently provided updates
|
||
|
|
and information on variation between ULTRIX systems.)

|
|
|
||
|
|
== [1.4] ==
|
||
|
|
|
||
|
|
* Does not use compile time determined values
|
||
|
|
for the stack base. This no longer works on Sun 3s, since Sun 3/80s use
|
||
|
|
a different stack base. We now use a straightforward heuristic on all
|
||
|
|
machines on which it is known to work (incl. Sun 3s) and compile-time
|
||
|
|
determined values for the rest. There should really be library calls
|
||
|
|
to determine such values.
|
||
|
|
|
||
|
|
|
||
|
|
== [1.3] ==
|
||
|
|
|
||
|
|
* Fixed spurious
|
||
|
|
assembly language assignments to TMP_SP. Only the assignment in the PC/RT
|
||
|
|
code is necessary. On other machines, with certain compiler options,
|
||
|
|
the assignments can lead to an unsaved register being overwritten.
|

Known to cause problems under SunOS 3.5 WITHOUT the -O option. (With
