changes in sbcl-0.6.8 relative to sbcl-0.6.7:

+* The system is now under CVS at SourceForge (instead of the
CVS repository on my home machine).
-?? The INSTALL file has been updated with some information
- about using anonymous CVS to download the most recent version
- from SourceForge.
-?? There's now code in the tests/ subdirectory to run the system
- through the clocc/ansi-tests/ suite, and to run additional
- SBCL-specific regression tests as well. (It's not particularly
- mature right now, but it's a start.)
-?? The system now uses code based on Colin Walters' O(N)
+* The new signal handling code has been tweaked to treat register
+ contents as (UNSIGNED-BYTE 32), as the old CMU CL code did,
+ instead of (SIGNED-BYTE 32), as the C header files have it. (Code
+ downstream, e.g. in debug-int.lisp, has implicit dependencies
+ on the unsignedness of integer representation of machine words,
+ and that caused the system to bomb out with infinite regress
+ when trying to recover from type errors involving signed values,
+ e.g. (BUTLAST '(1 2 3) -1).)
+* (BUTLAST NIL) and (NBUTLAST NIL) now return NIL as they should.
+ (This was one of the bugs Peter Van Eynde reported back in July.)
+* The system now uses code inspired by Colin Walters' O(N)
implementation of MAP (from the cmucl-imp@cons.org mailing
list, 2 September 2000) when it can't use a DEFTRANSFORM to
inline the MAP operation, and there is more than one
single sequence argument). (The old non-inline implementation
of the general M-argument sequence-of-length-N case required
O(M*N*N) time when any of the sequence arguments were LISTs.)
-?? Raymond Wiker's port of CMU CL's RUN-PROGRAM has been added.
-(?? Don't forget to mention Colin Walters and Raymond Wiker in the
- CREDITS file.)
-?? The debugger now flushes standard output streams before it begins
+* The QUIT :UNIX-CODE keyword argument has been renamed to
+ QUIT :UNIX-STATUS. (The old name still works, but is deprecated.)
+* Raymond Wiker's patches to port RUN-PROGRAM from CMU CL to SBCL
+ have been added.
+* Raymond Wiker's patches to port dynamic loading from Linux to
+ FreeBSD have been added.
+* The BUGS file is now more nearly up to date, thanks in large part
+ to Martin Atzmueller's review of it.
+* The debugger now flushes standard output streams before it begins
its output ("debugger invoked" and so forth).
-?? The two problem cases reported by Peter Van Eynde on 8 Sep 2000,
- (BUTLAST '(1 2 3) -1) and (MAKE-LIST -1), now work, and test cases
- have now been added to the regression test suite to keep them
- from appearing again. (This was a repeat appearance, alas!)
- As the regression test system gets more mature, I intend to add
- most future fixed bugs to it, but at this point I'm still playing
- with it.
-?? The patch for the SUBSEQ bug reported on the cmucl-imp mailing
- list 12 September 2000 has been applied to SBCL.
-?? Martin Atzmueller's versions of two CMU CL patches, as posted on
- sbcl-devel 13 September 2000, have been installed. (The patches fix
- a bug in SUBSEQ and <a bug in ??>.)
-?? A bug in signal handling which kept TRACE from working on OpenBSD
+* The core version number and fasl file version number have both
+ been incremented, because of incompatible changes in the layout
+ of static symbols.
+* FINISH-OUTPUT is now called more consistently on QUIT. (It
+ used to not be called for a saved Lisp image.)
+* Martin Atzmueller's version of a patch to fix a compiler crash,
+ as posted on sbcl-devel 13 September 2000, has been installed.
+* Instead of installing Martin Atzmueller's patch for the
+ compiler transform for SUBSEQ, I deleted the compiler transform,
+ and transforms for some similar consing operations.
+* A bug in signal handling which kept TRACE from working on OpenBSD
has been fixed.
-?? The signal handling bug reported by Martin Atzmueller on
- sbcl-devel 13 September 2000, which caused the debugger to
- get confused after a Ctrl-C interrupt under ILISP, has been fixed.
+* added enough DEFTRANSFORMs to allow (SXHASH 'FOO) to be optimized
+ away by constant folding
+* The system now defines its address space constants in one place
+ (in the Lisp sources), and propagates them automatically elsewhere
+ (through GENESIS and the sbcl.h file). Therefore, patching the
+ address map is less unnecessarily tedious and error-prone. The
+ Lisp names of address space constants have also been systematized.
+* CVS tags like dollar-Header-dollar have been removed from
+ the sources, because they have never saved me trouble and
+ they've been source of trouble working with patches and other
+ diff-related operations.
+* fixed the PROG1-vs.-PROGN bug in HANDLER-BIND (reported by
+ ole.rohne@cern.ch on cmucl-help@cons.org 2000-10-25)
+
+changes in sbcl-0.6.9 relative to sbcl-0.6.8:
+
+* DESCRIBE now works on CONDITION objects.
+* The debugger now handles errors which arise when trying to print
+ *DEBUG-CONDITION*, so that it's less likely to fall into infinite
+ regress.
+* The build system now uses an additional file, customize-target-features.lisp,
+ to allow local modifications to the target *FEATURES* list. (The point of
+ this is that now I can set up a custom configuration, e.g. with :SB-SHOW
+ debugging features enabled, without having to worry about propagating it
+ into everyone's system when I do a "cvs update".) When no
+ customize-target-features.lisp file exists, the target *FEATURES* list
+ should be constructed the same way as before.
+?? signal handling reliability
+?? fixed some bugs mentioned in the man page:
+ ?? DEFUN-vs.-DECLAIM
