测试内存泄露工具

	* Finally got the main line compiling again.  Ugh.  Chunk code
	looks a lot better however.

	* Before this time I've changed significantly the way the chunk
	routines account for pointers.  Now every pointer has a flags
	field which says whether fence post checking should be applied to
	it.

2001-05-23  Gray Watson  <>

	* Renamed _dmalloc_logpath to dmalloc_logpath to match the
	documentation and dmalloc.h.  Thanks Christoph.

2001-05-21  Gray Watson  <>

	* Solved problem with dmalloc_t and no sbrk.

	* Added INTERNAL_MEMORY_SPACE setting to the settings.dist file to
	help people with no sbrk function.

2001-03-29  Gray Watson  <>

	* Fixed some additional problems with start-file, start-count, and
	interval.

2001-03-28  Gray Watson  <>

	* Added the 'How It Works' section to the manual.

	* Removed necessity of strcat.

	* Removed use of strcpy internally.

	* Fixed problem with use of start-count and start-file not
	disabling the check-heap flag.

Mon Feb 26 12:17:25 2001  Gray Watson  <>

	* Releasing dmalloc version 4.8.2.

	* Installed new configure script to remove C++ requirement.

Sun Feb 25 18:58:37 2001  Gray Watson  <>

	* Making major changes to a number of routines.

Thu Feb 22 19:24:38 2001  Gray Watson  <>

	* Added more information to heap-check error messages on freed
	memory overwritten.  This is now possible since I unrolled the
	unions from chunk_loc.h.  Thanks to Robert Nielsen for pointing
	out this oversite.

Wed Feb 21 20:16:32 2001  Gray Watson  <>

	* Added strings to identify if the library was compiled with
 	LOCK_THREADS enabled.

Thu Nov 30 19:01:10 2000  Gray Watson  <>

	* Added heap checking when we shutdown if check-blank is enabled.
	This will verify that all of the freed memory was not overwritten.

Mon Nov 27 19:01:10 2000  Gray Watson  <>

	* Added a separate ALLOC_BLANK_CHAR and FREE_BLANK_CHAR to the
	settings.dist file.  Now the default 0xc5 character has been
	replaced with 0xda for dmalloc-allocated memory and 0xdf for
	dmalloc-freed memory.

Tue Nov 14 15:09:02 2000  Gray Watson  <>

	* Releasing dmalloc version 4.8.1.

	* Added --enable-shlib to configure which enables the building of
	shared libraries.

	libraries.

Mon Nov 13 10:47:21 2000  Gray Watson  <>

	* Added improvements to the shared library creation in the Makefile.

	* Fixed the #ident "..."; semi-colon problem.  Thanks to Jonathan.

Fri Nov 10 10:27:23 2000  Gray Watson  <>

	* Releasing dmalloc version 4.8.0.

Thu Nov  9 19:58:56 2000  Gray Watson  <>

	* Added OpenBSD port information.  Hopefully this will be close to
	Free/Net/... BSD as well.

Tue Nov  7 11:39:26 2000  Gray Watson  <>

	* Renamed malloc.h to malloc_funcs.h to avoid system conflicts.

	* Made log-unknown the default and depreciated the token.  Added a
	log-known token to _only_ report on known (file/line) memory.

	* Removed INSTALL.1 file because it was basically empty.

	* Added Troubleshooting section to the INSTALL manual.

Tue Oct 10 19:03:14 2000  Gray Watson  <>

	* Did a pre-release of 4.7.2 with the autoconfigure handling for
	VA Linux release.  Thanks guys.

	* Reorged dmalloc.h.3.  Ugh.

	* malloc_verify and dmalloc_verify now return
	[D]MALLOC_VERIFY_[NO]ERROR.

	* Just about every function now initializes the library.  This was
	not the case before with some information routines.

	* dmalloc_debug now takes an unsigned-int flags and returns the
	old debug flag value.  debug_current now returns an unsigned int
	flag value.

	* Added autoconfig handling of #ident.  I really hate Unix
	sometimes for its blatant disregard for anything approaching a
	standard.  Idiots.

Wed Sep 13 14:24:46 2000  Gray Watson  <>

	* Fixed a bug in chunk.c found by Ian Badcoe.

	* Improved the displaying of tokens my dmalloc utility.

Tue Jul 25 11:57:49 2000  Gray Watson  <>

	free-blank or alloc-blank.  I thought I fixed this before.

Mon Jul 24 15:30:04 2000  Gray Watson  <>

	* Releasing dmalloc version 4.7.0.

	* Added support for --disable-cxx and --enable-threads for turning
	on or off C++ and thread support.

Fri Jul 21 17:00:25 2000  Gray Watson  <>

	for an architecture.

	* Renamed USE_RET_ADDRESS to USE_RETURN_MACROS in return.h.

	* Added threaded C++ library support to Makefile.

Tue Jun 20 18:30:55 2000  Gray Watson  <>

	* Fixed problems with -p and -m not setting the debug flags.

	* Added 'force-linear' token and depreciated the 'allow-nonlinear'
	token.  Non-linear heaps really are the default these days (on AIX
	for example).  Now, you can enable the force-linear if you want to
	ensure a linear heap.

Wed May 17 11:29:55 2000  Gray Watson  <>

	* Releasing dmalloc version 4.6.0.

	* Fixed an incompatibility with the dmalloc_t -r, sbrk, and the

	problems with the dmalloc_t -r random debug flag.

Tue May 16 14:34:14 2000  Gray Watson  <>

	* Added BLOCK_ROUND macros to heap.h.

	hairy way too fast so backed it out.

	* Added SET_POINTER macro and cleaned some code.

	* Completely reworked the internal initialization values for the
	environmental variables to fix problems pointed out by Carlton
	Teel.  I was doing a (unsigned int)-1.  Yuck.

	* Fixed a bug found by Mcvey where the 1st dblock allocation in a
	block would not have been found in non-freed memory lists.  Yuck.

Mon May 15 11:46:21 2000  Gray Watson  <>

	* Moved to 'make cxx' and 'make installcxx' for building and
	installing the C++ version of the library.

	* Added autoconfiguration of the presence of a C++ compiler so it
	will attempt to build and install libdmallocxx.a if it can.

	* Removed DMALLOC_VERIFY_[NO]ERROR and replaced with
	DMALLOC_[NO]ERROR.

	* dmalloc_examine now returns DMALLOC_[NO]ERROR not [NO]ERROR.

	* Added initial mprotect configuration and stub function to the
	library.

Mon May  8 08:19:45 2000  Gray Watson  <>
