(In these cases the old code signalled an error and + looped endlessly, respectively.) Thus, DIRECTORY now works even + in the presence of dangling and cyclic symbolic links. +* Compiler trace output (the :TRACE-FILE option to COMPILE-FILE) + is now a supported extension again, since the consensus on + sbcl-devel was that it can be useful for ordinary development + work, not just for debugging SBCL itself. +* The default for SB-EXT:*DERIVE-FUNCTION-TYPES* has changed to + NIL, i.e. ANSI behavior, i.e. the compiler now recognizes + that currently-defined functions might be redefined later with + different return types. * Hash tables can be printed readably, as inspired by CMU CL code of Eric Marsden and SBCL code of Martin Atzmueller. -* a new slam.sh hack to shorten the edit/compile/debug cycle for - low-level changes to SBCL itself, and a new :SB-AFTER-XC-CORE - target feature to control the generation of the after-xc.core - file needed by slam.sh. -* Compiler trace output (the :TRACE-FILE option to COMPILE-FILE) - is now a supported extension again, since the consensus is that - it can be useful for ordinary development work, not just for - debugging SBCL itself. -?? more overflow fixes for >16Mbyte i/o buffers +* better error handling in CLOS method combination, thanks to + Martin Atzmueller porting Pierre Mai's CMU CL patches +* more overflow fixes for >16Mbyte I/O buffers +* A bug in READ has been fixed, so that now a single Ctrl-D + character suffices to cause end-of-file on character streams. + In particular, now you only need one Ctrl-D at the command + line (not two) to exit SBCL. +* fixed bug 26: ARRAY-DISPLACEMENT now returns (VALUES NIL 0) for + undisplaced arrays. +* fixed bug 107 (reported as a CMU CL bug by Erik Naggum on + comp.lang.lisp 2001-06-11): (WRITE #*101 :RADIX T :BASE 36) now + does the right thing. +* The implementation of some type tests, especially for CONDITION + types, is now tidier and maybe faster, due to CMU CL code + originally by Douglas Crosher, ported by Martin Atzmueller. +* Some math functions have been fixed, and there are new + optimizers for deriving the types of COERCE and ARRAY-ELEMENT-TYPE, + thanks to Raymond Toy's work on CMU CL, ported by Martin Atzmueller. +* (There are also some new optimizers in contrib/*-extras.lisp. Those + aren't built into sbcl-0.6.13, but are a sneak preview of what's + likely to be built into sbcl-0.7.0.) +* A bug in COPY-READTABLE was fixed. (Joao Cachopo's patch to CMU + CL, ported to SBCL by Martin Atzmueller) +* DESCRIBE now gives more information in some cases. (Pierre Mai's + patch to CMU CL, ported to SBCL by Martin Atzmueller) +* Martin Atzmueller and Bill Newman fixed some bugs in INSPECT. +* There's a new slam.sh hack to shorten the edit/compile/debug + cycle for low-level changes to SBCL itself, and a new + :SB-AFTER-XC-CORE target feature to control the generation of + the after-xc.core file needed by slam.sh. * minor incompatible change: The ENTRY-POINTS &KEY argument to COMPILE-FILE is no longer supported, so that now every function gets an entry point, so that block compilation looks a little more like the plain vanilla ANSI section 3.2.2.3 scheme. +* minor incompatible change: SB-EXT:GET-BYTES-CONSED now + returns the number of bytes consed since the system started, + rather than the number consed since the first time the function + was called. (The new definition parallels ANSI functions like + CL:GET-INTERNAL-RUN-TIME.) +* minor incompatible change: The old CMU-CL-style DIRECTORY options, + i.e. :ALL, :FOLLOW-LINKS, and :CHECK-FOR-SUBDIRS, are no longer + supported. Now DIRECTORY always does the abstract Common-Lisp-y + thing, i.e. :ALL T :FOLLOW-LINKS T :CHECK-FOR-SUBDIRS T. +* Fasl file version numbers are now independent of the target CPU, + since historically most system changes which required version + number changes have affected all CPUs equally. Similarly, + the byte fasl file version is now equal to the ordinary + fasl file version. + +changes in sbcl-0.7.0 relative to sbcl-0.6.13: +* There are new compiler optimizations for various functions: FIND, + POSITION, FIND-IF, POSITION-IF, FILL, COERCE, TRUNCATE, FLOOR, and + CEILING. Mostly these should be transparent, but there's one + potentially-annoying problem (bug 117): when the compiler inline + expands the FIND/POSITION family of functions and does type + analysis on the result, it can find control paths which have + type mismatches, and when it can't prove that they're not taken, + it will issue WARNINGs about the type mismatches. It's not clear + how to make the compiler smart enough to fix this in general, but + a workaround is given in the entry for 117 in the BUGS file. +* The doc/cmucl/ directory, containing old CMU CL documentation, + is no longer part of the base system. The files which used to + be in the doc/cmucl/ directory are now available as + . +* The default value of *BYTES-CONSED-BETWEEN-GCS* has been + doubled, to 4 million. (If your application spends a lot of time + GCing and you have a lot of RAM, you might want to experiment with + increasing it even more.) +?? The system's handling of top-level forms and EVAL-WHEN is now + more ANSI-compliant, fixing bugs + ?? IR1-3 and + ?? IR1-3a. + It's also done by much newer code, so there might be some new bugs, + but hopefully if so they'll be less fundamental and more fixable. +?? lots of tidying up internally: renaming things so that names are + more systematic and consistent, converting C macros to inline + functions, systematizing indentation planned incompatible changes in 0.7.x: * The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
