2000-01-21  Radey Shouman  <Radey_Shouman@splashtech.com>

	* schlep (typtrans-report!): Added CUMULATIVE? argument, typtrans
	table now includes per-file and cumulative fields.

	* schlep (typtrans-report!): Use WRITE rather than DISPLAY in
	printing, suppress writing type entries with zero uses.

	* schlep.scm: removed to bin.

2000-01-20  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* schlep.typ: Removed int declarations.

	* Makefile (*.txi): Added schlep.typ dependency.
	(sfiles): Added schlep.typ.

	* schlep.scm: Removed default suffix declarations.

2000-01-20  Radey Shouman  <Radey_Shouman@splashtech.com>

	* schlep.scm (vartype, declare-suffixes!, declare-suffix!):
	(compile1): Generalized suffix -> C type process.  Schlep programs
	may contain DECLARE-SUFFIXES directives, examples of which are
	generated by each compile in <name>-types.scm files.  Longer
	suffixes override shorter suffixes, recent declarations override
	earlier (with a warning message).  The effect of a
	DECLARE-SUFFIXES is limited to the local scope if not at top
	level.

	(read-local-suffixes): Default suffixes for a compile are read
	from "schlep.typ" in the same vicinity as the file being compiled.
	The contents of "schlep.typ" look like the CDR of a
	DECLARE-SUFFIXES form.  The default suffixes at load time are read
	from "schlep.typ" in (program-vicinity) for schlep.

	(outtype): Types may be strings, so any C type may be used.

2000-01-17  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* sys.h (LCK, ENTRY, SEGD): Changed to typedef struct.

2000-01-14  Radey Shouman  <Radey_Shouman@splashtech.com>

	unless they begin with ' (as in PROVIDED? arguments), in which
	case upcase them.

Thu Jan 13 23:15:43 EST 2000  Aubrey Jaffer  <jaffer@aubrey.jaffer>

	* Makefile (VERSION): Bumped from 1a4 to 1a5.

2000-01-09  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>

	* schlep.scm (compile1): Delete empty *.txi files.

2000-01-08  Radey Shouman  <Radey_Shouman@splashtech.com>

	* schlep.scm (schlep-read, compile1): Made separate *features*
	namespace for files being compiled by schlep, so that PROVIDE
	works reasonably with defmacros.  'schlep is no longer PROVIDEd by
	schlep.scm, except when actually reading input.

	(include-defmacros, compile-top, compileh-top): Recursively
	read REQUIREd or LOADed Scheme files in
	(PROGRAM-VICINITY) applying any DEFMACROs that are found.  In this
	way defmacros common to several files may be defined only once.

2000-01-06  Radey Shouman  <Radey_Shouman@splashtech.com>

	* schlep.scm (compile-if): Removed unnecessary restrictions on
	location PROVIDED? and DEFINED? forms.

	* schlep.scm (compile-if, compile-top-if, compile-to-sharp-if):
	Abstracted compilation to #if cpp statements.  Allow quoted
	argument in PROVIDED? forms.

2000-01-04  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>

	* schlep.scm (compile-if): compiles DEFINED? and PROVIDED? as
	#ifdef.

2000-01-04  Radey Shouman  <Radey_Shouman@splashtech.com>

	* schlep.scm (compile-top-if): Changed handling of DEFINED? so
	that argument must be a string or symbol, which is c-ified.
	Because strings are allowed uppercase C identifiers may be used.

	(compile-top, do-defmacro):  Added defmacros.

1999-12-17  Radey Shouman  <Radey_Shouman@splashtech.com>

1999-10-20  Radey Shouman  <radey@cjlinux.colorage.net>

	* schlep.scm (vartype): Made more robust for fooPTR or fooTAB
	names.
	(compile-exp): Support for OFFSET-ARRAY added.
	(vartype): Made correct for the case of ARRAY or PTR
	types with names of length 4. Eg (vartype 'xptr) used to cause an
	error.

1999-10-18  Radey Shouman  <Radey_Shouman@splashtech.com>

	* schlep.scm (document-args->macros, document-substitute): Merge
	all argument lists from @defunx forms together when defining
	argument macros.  Warn if an argument macro other than @0 is
	ambiguous.

1999-10-15  Radey Shouman  <Radey_Shouman@splashtech.com>

	* schlep.scm (compile-exp): Fix to compile expressions returning

	warnings by generating a tail label in a function definition only
	if it will be used.

	* schlep.scm (compileh-top, compile-top, out-sharpdef): Map
	(PROVIDE ...) to #define.

1999-07-08  Radey Shouman  <Radey_Shouman@splashtech.com>

Subject: DATABASE

I made several modifications. The major items are:

1. adding some performance reporting
2. fixing parent-insert-update
3. Fixing CACHING special cases
4. Testing behavior with empty blocks and missing pointers
5. Found PREV bug (but Not fixed yet)

Detailed change inventory:

(items in parens are redos of stuff we did at last DMC session,
as i didnt have the current code)

ADDED SOME PERFORMANCE STATISTICS:
1. added stat code at front of BLINK (STATS, CSTATS, CLEAR-STATS)
2. added ctrs to BT-X, BLK-READ/WRITE, PUT, DELETE-BLK,
   GET-ENT, TRY-GET-ENT, cache-checking routines
2a. added CLEAR-STATS call to INIT-SYS!
3. added VALUE arg to ADD! also starting-value and increment, aka REMOVE!
5. Restored SHOW-BUFFERS to ENT (was SHOW-ACCESS!),
  improved output format, added flag to
  allow filtering out of reclaimed buffers, added abbreviation (SB).

UPDATE CODE:
14. rewrote PARENT-INSERT-UPDATE to be an atomic operation.
   sadly, a fair bit of the work falls onto CHAIN-PUT; perhaps once its
   working we can figure out a better structure?
   Fix has been tested wtih 200 ADDs; however, the screw cases where the
   NEXT-KEY is in a different block -- and worse, where there are intervening
   empty blocks -- HAVE NOT BEEN TESTED YET.
16. Added global var DEFER-INSERT-UPDATES to force deferral of parent-updates
   for testing other code (Everything seems to survive it except PREV (see #18)
17. Added global DEFER-BLOCK-DELETES to force deferral of block-reclamation.
   Running with it on does not seem to cause any malfunctions in NEXT or PREV.

MISC:
9. changed FPRINTF to take F format (precision arg doesnt work, though)
10. Extended PACKET structure (SCHEME only)
11. fixed BLK-FIND-POS to return location of PREVIOUS key (see #12)
12. fixed PREV code to use #11 to avoid redundant block scans
    (MORE TO BE DONE: Fix its CACHE code to do so also)
13. Moved orphaned  "as we go" comment in BLINK back to BLK-FIND-POS
15. Started writing a design notes file
20. Fixed CHAIN-NEXT and CHAIN-PUT to update HAN-LAST optimally
    (passed though the PACKET). Things still work; a quick test indicates
    its helpful for NEXT but for some reason the fix ISNT helping for PUTs --
    at least not in the test i ran. (see observation 6)

REDOS:
4. (put in the 1-line mod to CHAIN-FIND-PREV-ENT)
6. (added ENT-WRITE calls to DELET-BLK and PARENT-DEL-UPDATE. But see #8)
19. (moved SET-HAN-LAST call into CHAIN-FIND-ENT)

(NOT REDONE:
   - the changed i/o message format
   - buffer aging tweaks
   - anything else I coundn't recall)

BUGS:
7. CUTE BUG: RELEASE-ENT was writing over the age=128 that AMNESIA-ENT set,
  thus preventing their buffers from being reclaimed preferentially!!!
  (examples traces appear as OBS #5) In any case, the right thing to do is
  simply to splice the ENT out directly, then you dont have to
  waste time searching for it. (I believe you said you were doing this, so
  I'll leave it alone for now.)

8. CUTE BUG#2: cant put ENT-WRITE in PARENT-DELETE-UPDATE, because
CHAIN-REM releases the block; have to put it into CHAIN-REM instead!!
(I dont know how we did it last time; the probem only shows up
on index-level deletes; also, fix saves a block write.)

	* prev.scm (at-root-level?): now checks first to see if ROOT? blk.

Fri Mar 20 13:31:59 1992  Aubrey Jaffer  (jaffer at PIXEL)

	* ent.scm (free-blk!): now calls amnesia-ent!.

	* defs.h (amnesia-ent!): created.

	* ent.scm (get-ent): now does not read blk when given ACCWRITE.

	* ent.scm (flush-and-del-buffer): now checks that ent is not
	ACCWRITE or ACCPEND.

	* ent.scm (flush-buffer): removed.

	* defs.scm ent.scm (BLK-TYP?): created and used.

	* ent.scm (create-new-blk-ent): Backs out if flc-fill fails.

	* ent.scm (fill-flc!): now does one disk write to extend the file.
	fill-flc! ==> flc-fill and returns #t on success.  #f if no more
	disk available or bt-rem failed.  Prints out error message if no
	more disk space available.

	* blink.scm ent.scm (create-new-blk-ent fill-flc! free-blk!
	flush-flc!): move from blink.scm to ent.scm.  Now all use of
	ENT-ACC is in ent.scm.

	* handle.scm (bt-open bt-create): commented out call to
	(check-access!) because Jonathan keeps program entries locked.

STATUS: (prev) working ( for (test1) data); needslarger test
        index-split fixed (cant call INDEX-SPLIT before INIT-NEXT-BLK!)
add multiple filenames;  warning message if filename does not
  match database name.
allow blk sizes to be specified in superblock
FLUSH on CLOSE-SEG! needs to REMOVE the entries for the database
  closed from the entry table, as well as writing out the dirty entries
flush-buffers wrong.
add DELETE-ENT and freelist B-tree
fix TSCAN! to verify key squencing
