have been added.
* Raymond Wiker's patches to port dynamic loading from Linux to
FreeBSD have been added.
-?? The debugger now flushes standard output streams before it begins
+* 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).
-?? FINISH-OUTPUT now works better than it did before. (It used to
- have trouble with characters which weren't followed by a linefeed.)
- ?? Remember to remove this from BUGS.
-?? 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.
- ?? Remember to remove this from the port-specific section of BUGS.
-?? 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
+* 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.
+* fixed bug 1 (error handling before read-eval-print loop starts), and
+ redid debugger restarts and related debugger commands somewhat while
+ doing so:
+ ** The QUIT debugger command is gone, since it did something
+ rather different than the SB-EXT:QUIT command, and since it never
+ worked properly outside the main toplevel read/eval/print loop.
+ Invoking the new TOPLEVEL restart provides the same functionality.
+ ** The GO debugger command is also gone, since you can just invoke
+ the CONTINUE restart directly instead.
+ ** The TOP debugger command is also gone, since it's redundant with the
+ FRAME 0 command, and since it interfered with abbreviations for the
+ TOPLEVEL restart.
+* fixed bugs in DEFCONSTANT ANSI-compatibility:
+ ** DEFCONSTANT now tests reassignments using EQL, not EQUAL, in order to
+ warn about behavior which is undefined under the ANSI spec. Note: This
+ is specified by ANSI, but it's not very popular with programmers.
+ If it causes you problems, take a look at the new SB-INT:DEFCONSTANT-EQX
+ macro in the SBCL sources for an example of a workaround which you
+ might use to make portable ANSI-standard code which does what you want.
+ ** DEFCONSTANT's implementation is now based on EVAL-WHEN instead of on
+ pre-ANSI IR1 translation magic, so it does the ANSI-specified thing
+ when it's used as a non-toplevel form. (This is required in order
+ to implement the DEFCONSTANT-EQX macro.)
+ ** (DEFCONSTANT X 1) (DEFVAR X) (SETF X 2) no longer "works".
+ ** Unfortunately, non-toplevel DEFCONSTANT forms can still do some
+ funny things, due to bugs in the implementation of EVAL-WHEN
+ (bug #IR1-3). This probably won't be fixed until 0.7.x. (Fortunately,
+ non-toplevel DEFCONSTANTs are uncommon.)
+* The core file version number and fasl file version number have been
+ incremented, because the old noncompliant DEFCONSTANT behavior involved
+ calling functions which no longer exist.
+* removed bug 21 from BUGS, since Martin Atzmueller points out that
+ it doesn't seem to affect SBCL after all
+* The system now recovers better from non-PACKAGE values of the *PACKAGE*
+ variable.
