The + SB-EXT:DISABLE-DEBUGGER and SB-EXT:ENABLE-DEBUGGER functions have + been added to allow this functionality to be controlled from ordinary + Lisp code. (ENABLE-DEBUGGER should help people like the Debian + maintainers, who might want to run non-interactive scripts to build SBCL cores which will later be used interactively.) * minor incompatible change: The LOAD function no longer, when given a wild pathname to load, loads all files matching that pathname. Instead, an error of type FILE-ERROR is signalled. +changes in sbcl-0.7.6 relative to sbcl-0.7.5: + * bug fix: Floating point exceptions are treated much more + consistently on the x86/Linux and PPC/Linux platforms. + * Array initialization with :INITIAL-ELEMENT is now much faster for + cases when the compiler cannot open code the array creation, but + does know what the UPGRADED-ARRAY-ELEMENT-TYPE will be. General + array accesses have also seen a speed increase. + * bug fix: LOAD :IF-DOES-NOT-EXIST NIL now works when file type is + specified. (This was at the root of some bad interactions between + SBCL and ILISP: thanks to Gregory Wright for diagnosing this and + reporting the bug.) + * bug fix: Internal error arguments for undefined functions are now + computed correctly on the PPC/Linux platform. + * bug fix: Bad &REST syntax is now checked correctly. (thanks to + Raymond Toy's patch for CMU CL) + * Support for the Solaris 9 operating environment has been included + (thanks to Daniel Merritt) + * A very ugly but hopefully complete draft of the missing FFI chapter + of the manual has been created by reformatting the corresponding + CMU CL manual chapter into (currently very ugly and incoherent) + DocBook and bringing it up to date for SBCL behavior. Thus, the + manual is now essentially complete, at least by my extreme + once-and-only-once standards, whereby it's acceptable to refer to + the doc strings of SB-EXT functions as the primary documentation. + * The fasl file version number has changed again, due to cleanup of + (user-invisible) bitrotted stuff. (E.g. *!INITIAL-FDEFN-OBJECTS* + is no longer a static symbol.) + +changes in sbcl-0.7.7 relative to sbcl-0.7.6: + * An alpha-quality port to the parisc architecture running Linux, + based on the old CMUCL backend, has been made. This, even more so + than the other backends, should be considered still a work in + progress; known problems include that the Linux kernel in 64-bit + mode does not propagate the correct sigcontext structure to + userspace, and consequently SBCL on a parisc64 kernel will not + work yet. + * fixed bug 189: The compiler now respects NOTINLINE declarations for + functions declared in FLET and LABELS. (I.e. "LET conversion" is + suppressed.) Also now that the compiler is looking at declarations + in the environment, it checks optimization declarations as well, + and suppresses inlining when (> DEBUG SPEED). + * More fixes have been made to treatment of floating point exception + treatment and other Unix signals. In particular, floating point + exceptions no longer cause Bus errors on the SPARC/Linux platform. + * The detection and handling of control stack exhaustion (infinite + or very deeply nested recursion) has changed. Stack exhaustion + detection is now done by write-protecting pages at the OS level + and applies at all optimization settings; when found, a + SB-KERNEL:CONTROL-STACK-EXHAUSTED condition (subclass of + STORAGE-CONDITION) is signalled, so stack exhaustion can no longer + be caught using IGNORE-ERRORS. + * Bugs 65, 70, and 109 fixed: The compiler now preserves invariants + correctly when transforming recursive LABELS functions to LETs. + (thanks to Alexey Dejneka) + * Bug 48a./b. fixed: SYMBOL-MACROLET now refuses to bind symbols + that are names of constants or global variables. + * Bug fix: DEFINE-ALIEN-ROUTINE now declaims the correct FTYPE for + alien routines with docstrings. + * Bug 184 fixed: Division of ratios by the integer 0 now signals an + error of type DIVISION-BY-ZERO. (thanks to Wolfhard Buss and + Raymond Toy) + * Bug fix: Errors in PARSE-INTEGER are now of type PARSE-ERROR. + (thanks to Eric Marsden) + * Bug fix: COERCE to (COMPLEX FLOAT) of rationals now returns an + object of type (COMPLEX FLOAT). (thanks to Wolfhard Buss) + * Bug fix: The SPARC backend can now compile functions involving + LOGAND and stack-allocated arguments. (thanks to Raymond Toy) + * Bug fix: We no longer segfault on passing a non-FILE-STREAM stream + to a functions expecting a PATHNAME-DESIGNATOR. + * Bug fix: DEFGENERIC now enforces the ANSI restrictions on its + lambda lists. (thanks to Alexey Dejneka) + * Bug fix: changed encoding of PCL's internal MAKE-INSTANCE + functions so that EXPORTing the name of the class doesn't cause + MAKE-INSTANCE functions from earlier DEFCLASSes to get lost (thanks + to Antonio Martinez for reporting this) + * Bug 192 fixed: The internal primitive DATA-VECTOR-REF can now be + constant-folded without failing an assertion. (thanks to Einar + Floystad Dorum for reporting this) + * Bugs 123 and 165 fixed: array specializations on as-yet-undefined + types are now dealt with more correctly by the compiler. + * Minor incompatible change: COMPILE-FILE-PATHNAME now merges its + OUTPUT-FILE argument with its INPUT-FILE argument, resulting in + behaviour analogous to RENAME-FILE. This puts its behaviour more + in line with ANSI's wording on COMPILE-FILE-PATHNAME. (thanks to + Marco Antinotti) + * The fasl file version number has changed again. (because of the + bug fix involving the names of PCL MAKE-INSTANCE functions) + +changes in sbcl-0.7.8 relative to sbcl-0.7.7: + * A beta-quality port to the mips architecture running Linux, + based on the old CMUCL backend, has been made. It has been tested + on a big-endian kernel, and works sufficiently well to be able to + rebuild itself; it has not been tested in little-endian mode. + * fixed bug 120a: The compiler now deals correctly with IFs where + the consequent is the same as the alternative, instead of + misderiving the return type. (thanks to Alexey Dejneka) + * fixed bug 113: Logical pathnames are now dumpable (the logical + host is resolved at load-time, throwing an error if it is not + found). + * fixed bug 174: FORMAT's error message is slightly clearer when a + non-printing character is used in a format directive. + * fixed several bugs in compiler checking of type declarations, i.e. + violations of the Python "declarations are assertions" principle + (thanks to Alexey Dejneka) + * fixed several bugs in PCL's error checking (thanks to Gerd + Moellmann) + * fixed bug in printing of FILE-ERROR (thanks to Antonio Martinez) + planned incompatible changes in 0.7.x: * When the profiling interface settles down, maybe in 0.7.x, maybe later, it might impact TRACE.
