allocation block when it is allocated. The 'free-blank' token
clears a pointer when it is freed.
* Also, the library was clearing the user spaces of an allocated
chunk with the alloc-blank character and the non-user spaces with
the free-blank character. This seemed confusing and wrong so now
all sections of an allocated chunk are cleared with the
alloc-blank character.

* Added on_exit and atexit support to auto-call malloc_shutdown.
Thanks much to Manfred, Dave, Scott, and Rich.
* Added -m (minus) option to malloc_dbg. Why didn't I think of
this before?
Tue Nov 2 16:45:32 1993 Gray Watson ()
* Fixed problem with getenv processing.
Wed Oct 20 19:30:34 1993 Gray Watson ()
* Renamed malloc_debug to malloc_flags.
* Added all malloc utility functions to malloc_lp.c. Now
programs can call malloc_shutdown (for instance) without fear.
See malloc_lp.h.
Sat Oct 16 19:18:53 1993 Gray Watson ()
* removed debug token log-ra, log-unknown should be enough.
Thu Oct 14 19:48:42 1993 Gray Watson ()
* malloc_heap_map() -> malloc_log_heap_map() for consistency.
Wed Oct 13 17:58:55 1993 Gray Watson ()
* Added malloc_log_unfreed() to dump non-free memory to
logfile. Good for comparing heaps to see differences.
* Added -p flag to malloc_dbg to allow adding of tokens to
debug value.
* added DEBUG_LOG_STAMP to add timestamps to log entries.
* Added malloc_log_stats() to dump stats to log file.
* Re-added cfree() call. No reason not to have it.
Sun Sep 26 14:36:54 1993 Gray Watson ()
* For new version 2.0.0b. Major changes. Lots of procedures
moved around. Rewrote a large part of get_bblocks and removed
get_bblock_adm.
* Releasing version 1.3.4.
* Added -std1 configuration changes and bcopy fixes.
* Fixed up the messages to provide more information and to just
reflect reality. Some real dumb errors found.
* Added malloc_debug_current() and #ifdef STDC instead of
#if. Thanks Scott.
Wed Sep 22 00:43:54 1993 Gray Watson ()
* Removed log-bad-pnt. What a dumb token! Unnecessary!
Mon Sep 20 20:36:23 1993 Gray Watson ()
* Releasing version 1.3.3.
* Added ALLOW_FREE_NULL defines because of some systems allowing
free(0). Yeach! Thanks Dave.
Fri Sep 10 17:10:45 1993 Gray Watson ()
* Fixed debug value changes in mid-stream. Repaired configuration
error with memcpy/bcopy and memcmp/bcmp. Thanks Marc.
Tue Sep 7 00:49:50 1993 Gray Watson ()
* Renamed all error codes to ERROR_*. Added ERROR_IS_FREE and
changed some of the already-free errors to this. Reworded some
error messages and added free's file/line into to log_bad_pnt.
Mon Aug 30 17:23:47 1993 Gray Watson ()
* Added prototypes for _malloc_strcpy, etc. functions to
malloc_dbg.h per Scott's comments.
Thu Aug 26 19:06:45 1993 Gray Watson ()
* Released version 1.3.2. Uploaded to the ftp site.
* Removed MALLOC_TRACE and malloc_dbg -t. Replaced by
MALLOC_ADDRESS:0 functionality and logging of a message every time
malloc_address is seen.
* Fixed some dumb const problems. Have to now preprocess
malloc_dbg.h from start const.h end. Yeach!
* Added MALLOC_LOGFILE feature where %d in the string will be
replaced with the pid of the process. Had to add getpid to
configure and compat.
* Fixed some problems with compat.h defines.
Tue Aug 24 00:35:49 1993 Gray Watson ()
* Releasing version 1.3.1.
* Added log-ra token to log specific information about non-freed
memory with only return-address information (NOTE: later removed).
* Added the beginnings of return-address handling. Thanks Dave.
Need to resolve some XXX sections in chunk and get more
architecture/compiler hacks in return.h. Along the way had to
change the malloc_examine() arguments to add ret_attr.
* Added -L or --list to malloc_dbg to list all the rc-file tags.
* Fixed some problems in chunk.c. Thanks Dave. Renamed
malloc_str.[ch] to be arg_check.[ch].
Tue Aug 17 16:22:20 1993 Gray Watson ()
* Releasing version 1.3.0.
* Fixed some ansi compiler problems via patch from Manfred
Hauswirth.
Thu Aug 12 18:11:01 1993 Gray Watson ()
* Added MALLOC_TRACE variable and malloc_dbg -t functionality for
tracing an address and logging messages about it. NOTE: this
was later removed -- replaced by MALLOC_ADDRESS:0.
Tue Aug 10 16:43:07 1993 Gray Watson ()
* Made some minor fixes. Thanks Marc.
Mon Jul 26 05:50:27 1993 Gray Watson ()
* Added some C++ from Peter Miller to the manual.
Fri Jul 23 01:36:09 1993 Gray Watson ()
* Removed LGPL copyright and put in its place fully free
software notices.
Thu Jul 22 17:35:23 1993 Gray Watson ()
* _malloc_perror renamed to _malloc_error and made some other
minor changes.
Tue Jul 20 01:52:02 1993 Gray Watson ()
* Added smallest_block runtime calculations.
Mon Jul 19 12:20:58 1993 Gray Watson ()
* Made malloc_address exported per Dave's comments so it
can be setable by debugger at runtime.
* Added Dave's idea of auto-sensing of shell by malloc_dbg.
Also added -C option to malloc_dbg to force cshell output.
* Removed the dblock checking tokens CHECK_DBLOCK and
CHECK_DB_FENCE for a couple different reasons. I never liked them
anyway! I also renumbered CHECK_FREE and CHECK_FUNCS in the
process.
* Fixed a number of int/long problems since Dave is running
malloc on a 64 bit alpha.
* Made a number of changes to the configure scripts and conf.h per
Dave's comments. Added BASIC_BLOCK and ALLOCATION_ALIGNMENT
to the auto-config stuff.
Fri Jul 16 00:01:31 1993 Gray Watson ()
* Changed malloc_dbg per new ARGV_MAYBE. Made some various
changes from ints to longs per some useful comments from Dave
Hill.
Tue Jul 13 01:53:32 1993 Gray Watson ()
* Version 1.2.6 released.
* Posting to bsdi. Last minute porting changes.
Mon Jul 12 02:03:25 1993 Gray Watson ()
* Finished new catch-null token.
Tue Jul 6 16:04:17 1993 Gray Watson ()
* Added 'catch-null' token for quitting as soon as we get a sbrk
failure (i.e. the swap is full or something) as opposed to
returning NULL.
Sat Jun 19 14:49:42 1993 Gray Watson ()
* Minor changes to configuration and notes files.
Tue Jun 15 10:29:13 1993 Gray Watson ()
* Released version 1.2.5.
* Made some last minute changes to the manual.
Wed Jun 9 15:12:21 1993 Gray Watson ()
* Fixed small malloc_dbg token bug from Peter Miller.
Thu Jun 3 16:01:14 1993 Gray Watson ()
* Added index to manual, removed shar files in place of Makefile
variables.
Mon May 24 12:58:06 1993 Gray Watson ()
* Added -r and -k options for auto-unsetting of variables or
keeping of variables with malloc_dbg when setting a tag.
* Added const checking to configure and reordered some include
files to put conf.h on top.
Tue May 18 20:07:41 1993 Gray Watson ()
* Added log-bad-space token and added expand_buf into chunk.c.
* Create log_bad_pnt in chunk. Probably broke stuff.
Translated some flag to BIT_FLAG format.
* Updated README and started ftp site thanks to Doug Balog.
Thu May 13 00:56:39 1993 Gray Watson ()
* Released version 1.2.4.
* Pretty stable now for a while. Trying to get access to a ftp
for distribution ease.
Thu May 6 11:26:03 1993 Gray Watson ()
* Added new fix-patch script for myself. Fixed malloc_t by
removing LOCAL/EXPORT, etc.
Fri Apr 30 15:26:12 1993 Gray Watson ()
* Removed some heap checks in malloc.c from Bali Jatinder's
comments and fixed some of the error strings.
* Moved around some defines and changes include ordering.
* Added -v option to malloc_dbg to provide verbose output
especially for dumping currently set debug tokens from
MALLOC_DEBUG variable.
Mon Apr 19 16:04:17 1993 Gray Watson ()
* Released version 1.2.3.
* Made some changes to a lot of comments, notes files, and ttd
file.
Thu Apr 15 17:44:41 1993 Gray Watson ()
* Renamed malloc.h to malloc_dbg.h and libmalloc.a to
libmalloc_dbg.a. Added heap-extension checking and verification
to make sure no-one extends the heap using sbrk behind out back.
Fixed calloc to have the number of elements be a size_t to (WHY??
It's not a size!!). Fixed malloc_t free problems.
Wed Apr 14 18:11:00 1993 Gray Watson ()
* Released version 1.2.2.
* Added some more point checking tests to malloc_str. Added
MALLOC_SIZE to some more places. Completely ifdef'ed compat.h.
If cannot open logfile, now it complains and continues. Removed
stdarg from malloc_dbg.
Fri Apr 9 01:50:17 1993 Gray Watson ()
* Released version 1.2.1.
* Made various other changes. Backed out some printf changes.
Added SIZE_T defines and fixed up STDC defines.
Thu Apr 8 17:41:59 1993 Gray Watson ()
* Changed to void * internally from char * and put STDC defines in
malloc.h for ANSI folks. Why did the ANSI idiots drop the return
value from free? Dumb!
* Made a number of changes per suggestions from the net. Added
some size_t defines for AIX junk (that's right Scott junk). Cut
down on the continuation strings, fixed some README and mallocrc
goofs, etc. Thanks to all.
Tue Apr 6 00:46:45 1993 Gray Watson ()
* Released version 1.2.0 to comp.sources.unix.
* Upgraded to version 1.2.0. Ready for 2nd release to
comp.sources.unix. Lots of work on the manual.
Mon Apr 5 18:28:05 1993 Gray Watson ()
* Finished adding token "check-funcs" to check the arguments of
some common string functions to see whether they are in the heap.
if so it tries to verify that the pointers are good.
Sun Apr 4 21:24:45 1993 Gray Watson ()
* Added token "log-unknown" to dump non-free unknown pointers as
well as known ones. Also cleaned up the displaying of the
pointers.
* comp.sources.unix is almost ready to post so lots of last minute
cleanups in the manual, etc.
* Started integration of function argument checking.
Tue Mar 30 19:36:27 1993 Gray Watson ()
* Changed malloc.h defines so malloc routines are handled as well
as the ALLOC macros.
* malloc_dbg program now reports on the token NAME and values.
* Added initial string files for string support in the future.
* A number of minor changes: fixed gcc compilation problems per
Scott's help, combined malloc_lp.h into malloc.h, cleaned most .h
and .c files.
Fri Mar 26 04:00:14 1993 Gray Watson ()
* Fixed post 1.1.6 problem with chunk.c. Boy do I need some
automated testing tools. Discovered the illusive localtime
fence-post error. Had a hard time tracking it down. Maybe due to
the fact that the checks were not being made on dblock fence posts
before?
* Released version 1.1.6
* Found some problems with malloc debug codes. Use of DB_FENCE
and CHECK_LISTS and some others were improper. A MALLOC_DEBUG
value of 0x403000 would crash all malloc programs. :-)
* Added some better comments to all files and cleaned up most
files too.
Fri Mar 12 18:35:02 1993 Gray Watson ()
* Released version 1.1.5.
Sat Feb 13 17:25:43 1993 Gray Watson ()
* Finished add a number of const operators to improve coding per
scott's recommendations.
Sat Jan 30 12:33:43 1993 Gray Watson ()
* Released version 1.1.4
* Took out the check_vars call inside of malloc_strerror since
_malloc_perror calls malloc_strerror which would go quickly
recursive. Thanks scott.
Tue Jan 5 00:00:00 1993 Gray Watson ()
* Posted version 1.1.3 shar files to comp.sources.unix.
Sat Jan 2 00:16:58 1993 Gray Watson ()
* Made last minute changes to solve some gcc/ansi errors and
to the manual to get things ready for the post.
Sun Dec 27 20:28:19 1992 Gray Watson ()
* Fixed problem with some external functions in malloc.c not
resetting the in_alloc flag. Also removed some testing of unsigned
variables < 0 in chunk.c per gcc 2.3.3 warnings.
* Released version 1.1.3.
Mon Dec 21 15:31:50 1992 Gray Watson ()
* Created the series of shar files in preparation to posting to
comp.unix.sources. Looking good.
Thu Dec 17 18:33:38 1992 Gray Watson ()
* Renamed a number of files to comply with the Sys5 12 character
restrictions (14 - 2 for RCS/CVS/SCCS). Yeach. malloc_debug ->
malloc_dbg.
Sat Nov 14 15:59:53 1992 Gray Watson ()
* Added all external functions to configure and conf.h even though
the library assumes that some functions will be resolved. Also
upgraded the version number to 1.01gamma (oooooh).
* Added print-perror debug token for logging messages to STDERR as
well as log-files. Removed stdio from the malloc library to make
sure it does not go recursive (alloc for stderr) at a bad time.
Wed Nov 11 18:19:49 1992 Gray Watson ()
* Moved the heap_check calls from chunk.c over to malloc so we can
be guaranteed that it gets called only once per user call.
chunk's routines often cross-call each other meaning that
heap-check was being run 5 times in realloc. YEACH!!
Tue Nov 10 17:55:53 1992 Gray Watson ()
* Added two new debug-tokens: log-blocks and heap-check-map. Also
made sure that heap_check was being called from everywhere.
Updated the manual and corresponding files.
* Added library functions that may not be defined. Updated the
conf.h.in and configure.in files to improve confiurability.
Upgraded the manual which still needs a lot of work (sigh).
Mon Nov 9 19:21:25 1992 Gray Watson ()
* Added configure, configure.in, conf.h.in, and Makefile.in to try
and conform with autoconf specs. What a bear. The documentation
for autoconf needs a whole bunch more examples, etc. Sigh.
Removed all the MEMORY and STRING defines, etc.
Thu Nov 5 22:13:18 1992 Gray Watson ()
* Released version 1.01b. Sending it off to some folks.
* Lots and lots of changes. Translated all programs into non-ansi
C dependence and then went back again when I found some problems
with my macros. :-) Took out all (and I mean all) Antaire
dependencies and defines.
Thu Oct 22 00:47:18 1992 Gray Watson ()
* Ran through most of the debug-flag functionality testing and
tweaking. Found some bugs on dblock handling and some messed up
logic with the way the LOG flags were working.
* malloc_debug is looking good. It now outputs C or Bourne shell
code and seems to work in both environments. What do sh folks use
in the place of c-shell aliasing? I guess use bash. :-)
Wed Oct 21 03:27:35 1992 Gray Watson ()
* Major changes. I sort of went overboard tonight. I integrated
the new malloc_debug program which sets all the debug variables
for you. I also added a .mallocrc which you can define with tags
exactly the functionality you want to happen. No more levels!!
* Did some renaming of files, cleaned up some other things,
had to rework a number of items to get new debug flags working.
Tue Oct 20 18:06:36 1992 Gray Watson ()
* Removed useful.h requirements and integrated necessary
definitions into malloc.h.
* Transferred malloc.txt documentation into malloc.texinfo. Boy
is it nifty!! And damn easy!!!
* Major changes to improve general machine independence. Added
malloc_mach.h. Moved alloc.[ch] to malloc.[ch] for sanity
reasons.
Tue Oct 13 16:14:17 1992 Gray Watson ()
* Made various cosmetic changes. Fixed realloc inbound pointer
checking per MALLOC_ADDRESS. Fixed problem with MALLOC_ADDRESS
initialization to NULL causing free to "find" NULL pointers. :-)
* Separated the PERROR debug level and the KILL_SELF level. Now
(by default) all memory errors are logged at level 1 and above and
malloc kills itself at level 2 and above.
Mon Sep 28 23:24:36 1992 Gray Watson ()
* Added MALLOC_ADDRESS support for free. MALLOC_ADDRESS counts
now also apply to frees also.
Mon Sep 21 20:39:38 1992 Gray Watson ()
* Fixed some size problems with bounds checking enabled.
* Made free be able to report who freed a pointer. I don't know
why this wasn't caught before. free wasn't even using its
file/line arguments.
Thu Sep 3 03:23:39 1992 Gray Watson ()
* Added ability to realloc a NULL pointer with an ifdef to
disable. Useful in realloc loops where the first time you don't
have to alloc it.
Fri Aug 14 15:54:03 1992 Gray Watson ()
* Added a bunch of new environmental variables features:
MALLOC_ADDRESS now can have a :# argument. MALLOC_START now has
two formats, the old number and new file:line. Looks nice!
* Made a pass through chunk.c and fixed a number of problems where
debug output pnt/size did not match user-supplied information.
* Moved most of the debug variables into alloc.c from chunk.c and
added a standardized check_debug_vars() checking routine.
Tue Jul 21 16:06:13 1992 Gray Watson ()
* Fixed malloc count statistics. Removed duplicate malloc_count
variable from a number of places.
Mon Mar 23 10:49:25 1992 Gray Watson ()
* Released version 0.04
* New env variable features.
Thu Mar 12 19:28:34 1992 Gray Watson ()
* Fixed a large problem with chunk.c not reporting the correct
memory address when listing unfreed memory. This was discovered
when MALLOC_ADDRESS was not working correctly.
* Started ChangeLog.
