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, and because I also took the + opportunity to chop an unsupported slot out of the DEBUG-SOURCE structure. +* 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. +* The system now understands compound CONS types (e.g. (CONS FIXNUM T)) + as required by ANSI.
