Tue Oct 15 15:00:11 PDT 2002	Jason Downs ([e-mail])

	* samp1.cc: Remove.

	* gdbm.3, gdbm.texinfo: 1.8.3.

	* version.c: Version 1.8.3., modernize string (release date is in
	  American format).

	* gdbmreorg.c: Remove small memory leak.

	* Makefile.in: Use more subs from configure, remove mention of SunOS.
	  Add support for spec'ing an install time prefix via INSTALL_ROOT.

	* INSTALL: Remove extra text from top.

	* config.guess, config.sub: Update to latest versions.

	* autoconf.h.in: Regenerate.

	* configure.in: Modernize.

	* systems.h: HAVE_ST_BLKSIZE -> HAVE_STRUCT_STAT_ST_BLKSIZE.

Fri Sep 27 16:12:44 PDT 2002	Jason Downs ([e-mail])

	* Makefile.in: Remove `info' target from all, since we don't even
	  bother installing the one we built anyway.

	* Fix a few checks against dbf.read_write.

Wed Sep 25 15:19:00 PDT 2002	Jason Downs ([e-mail])

	* Makefile.in: Remove the dbm and ndbm routines from the main
	  library, moving them to gdbm_compat.  install-compat now
	  installs the compat headers and the library.  Increment the
	  MAJOR number of the shared library due to the removal of
	  the compat functions.

	* gdbm.3, gdbm.texinfo, version.c: 1.8.1; note gdbm_compat.

	* proto.h: Change _gdbm_fatal() to void.

	* update.c(_gdbm_fatal): Change function declaration to void.

	* update.c(_gdbm_fatal): Change default exit status to 1.

	* gdbmopen.c(gdbm_open): Remove setting of flags since we always check
	  it against the mask.

	* testdbm.c, testndbm.c: Added stdlib.h inclusions.

	* falloc.c(push_avail_block): Fixed extremely rare case where the
	  header avail table could fill up, causing us to over flow the
	  table, corrupting memory, and eventually crashing.  Also forced
	  merging of blocks within the scope of this routine (possibly
	  should force them whenever the header avail table is being used).

	* gdbmerrno.c: Fix error count, there are more than 18.

	* gdbmerrno.h: Fix typo; GDBM_OPT_ILLEGAL is 20.

	* gdbmopen.c: Fix typo; s/GDBM_OPENMASK/GDBM_WRITER/.

Tue May 18 19:25:25 PDT 1999	Jason Downs	([e-mail])

	* gdbm.3, gdbm.texinfo: Update for 1.8.

	* Makefile.in, configure.in: Switch to using libtool, but without
	  automake.

	* aclocal.m4, config.guess, config.sub, ltconfig, ltmain.sh: New
	  files (libtool 1.2).

Wed May 12 01:26:15 PDT 1999	Jason Downs	([e-mail])

	* gdbmopen.c, gdbmclose.c, gdbmreorg.c: check file_locking before
	  calling locking macros; add support for setting GDBM_NOLOCK in
	  gdbm_open().

	* gdbmdefs.h: add file_locking flag to gdbm_file_info.

	* gdbmconst.h, gdbm.proto: add GDBM_NOLOCK flag.

	* gdbmfdesc.c: new file, adds external gdbm_fdesc() routine.

	* gdbm.proto, gdbm.proto2: clean up, use __P, and compress.

	* gdbmerrno.h: kill the enum, add defines for errors.

	* gdbmsetopt.c, testgdbm.c: support GDBM_SYNC/GDBM_SYNCMODE.

	* gdbmopen.c: gdbm_open() now DEFAULTS to ``fast mode''; use
	  GDBM_SYNC to turn it off.  GDBM_FAST is obsolete and ignored.

	* gdbmconst.h: add GDBM_SYNC and GDBM_SYNCMODE.

	* proto.h, various source files: switch _ARGS to __P.

	* systems.h, various source files: kill word_t, just use int
	  everywhere.

	* configure.in, autoconf.h.in: remove alloca() goo and modernize.

	* many source files: replace all instances of alloca() with real
	  malloc()s and free()s.

	* update.c: don't deref NULL in _gdbm_fatal(), and don't use stdio.

[  The following are entries revived from a dead experimental branch. ]

	* gdbmopen.c (gdbm_open): actually initialize central_free and

Fri Jun  3 05:57:36 1994  Jason Downs  ([e-mail])

	* falloc.c (pop_avail_block): merge block with header, instead
	  of replace, since header may not be empty any longer.

	* falloc.c (_gdbm_alloc): pop a block off the stack when the
	  current header is half empty, instead of zero.

Fri Jun  3 05:11:33 1994  Jason Downs  ([e-mail])

	* gdbmstore.c (gdbm_store): don't alloc new disk if we're replacing
	  and the records are the same size. suggested by phil a long time
	  ago.

Fri Jun  3 03:47:46 1994  Jason Downs  ([e-mail])
        
	* falloc.c (_gdbm_put_av_elem): allow adjacent blocks to be
