STREAM no longer cause compiler notes to appear. + * enhancement: the system no longer resignals errors from --load and + --eval toplevel arguments as SIMPLE-ERRORS, which caused restarts + associated with the original error to be lost. (thanks to Ariel + Badichi) + * bug fix: ADJUST-ARRAY on multidimensional arrays used bogusly give + them a fill pointer unless :DISPLACED-TO or :INITIAL-CONTENTS were + provided. (reported by Cedric St-Jean) + * bug fix: circularity handling in the reader did not treat raw + structure slots correctly. (reported by Cedric St-Jean) + * bug fix: SERVE-EVENT occasionally signaled an error about bogus + file descriptors when there were none. + * bug fix: DEFINE-COMPILER-MACRO support of destructuring lambda-lists + was broken. (reported by Willem Broekema) + +changes in sbcl-1.0.21 relative to 1.0.20: + * new feature: the compiler is able to track the effective type of a + generic function across method addition and removal. + * new feature: SB-EXT:ATOMIC-INCF allows atomic incrementation of + appropriately typed structure slots without locking. + * new feature: SB-EXT:CALL-WITH-TIMING provides access to timing + information like those gathered by TIME using a programming-friendly + interface. + * new feature: TIME reports time taken even if the form performs a + non-local transfer of control. + * enhancement: reduced conservativism on GENCGC platforms: on + average 45% less pages pinned (measured from SBCL self build). + * bug fix: SB-EXT:COMPARE-AND-SWAP on SYMBOL-VALUE can no longer + mutate constant symbols or violate declaimed type of the symbol. + * bug fix: SB-THREAD:SIGNAL-SEMAPHORE could fail to wakeup threads + sleeping on the semaphore in heavily contested semaphores. + * bug fix: semaphores and condition variables were not interrupt + safe. + * bug fix: SB-THREAD:CONDITION-WAIT doesn't allow waits on mutexes + owned by other threads anymore. + * bug fix: FIND on lists called KEY outside the specified + subsequence. (reported by budden) + * bug fix: LOG doesn't use single-float intermediate results when + given mixed integer and double-float arguments, leading to better + precision. (reported by Bob Felts) + * bug fix: LOG with base zero returned values of inconsistent type. + +changes in sbcl-1.0.20 relative to 1.0.19: + * minor incompatible change: OPTIMIZE qualities + SB-C::STACK-ALLOCATE-DYNAMIC-EXTENT, SB-C::STACK-ALLOCATE-VECTOR, + and SB-C::STACK-ALLOCATE-VALUE-CELLS no longer exist. See documentation + and SB-EXT:*STACK-ALLOCATE-DYNAMIC-EXTENT* for details. + * documentation: some slot access efficiency guidelines have been + added to the user manual. + * optimization: ASSOC-IF, ASSOC-IF-NOT, MEMBER-IF, MEMBER-IF-NOT, + RASSOC, RASSOC-IF, and RASSOC-IF-NOT are now equally efficient + as ASSOC and MEMEBER. + * optimization: calls to ASSOC, MEMBER, and RASSOC can be transformed + to more efficient EQ-comparison versions more often. + * optimization: enhanced derivation of DOLIST iteration variable type + for constant lists. + * optimization: constant folding of simple (LIST ...) forms as DOLIST + arguments. + * optimization: runtime lookup of function definitions can be + elided in more cases, eg: (let ((x 'foo)) (funcall foo)). + * optimization: compiler is able to derive the return type of + (AREF (THE STRING X) Y) as being CHARACTER. + * optimization: CLRHASH on empty hash-tables no longer does pointless + work. (thanks to Alec Berryman) + * optimization: REPLACE deftransforms don't punt when :START1 or + :START2 is given + * bug fix: compiling DESTRUCTURING-BIND on constant list arguments + no longer emits a code deletion note. (reported by Andrew + Gasparovic) + * bug fix: bogus odd-number-of-keywords STYLE-WARNINGs from calls to + functions with an odd number of &OPTIONAL arguments, a &REST + argument, and one or more &KEY arguments at the call site. + * bug fix: STYLE-WARNINGs for functions with both &OPTIONAL and &KEY + arguments appeared at call sites as well. + * bug fix: fixed #425; CLOSE drops input buffers from streams, so + READ-LINE &co can no longer read from them afterwards. (reported + by Damien Cassou) + * bug fix: fixed #427: unused local aliens no longer cause compiler + breakage. (reported by Stelian Ionescu, Andy Hefner and Stanislaw + Halik) + * bug fix: non-local exit from a WITH-ALIEN form no longer causes + alien-stack leakage. (reported by Andy Hefner) + * bug fix: PROGV signals an error when an attempt to violate declared + type of a variable or bind a constant is made. + * bug fix: SET signals an error when an attempt to violate declared + type of a variable is made. + * bug fix: restart computation during the execution of a restart + test function no longer causes infinite recursion. (reported by + Michael Weber) + * bug fix: calling SB-COVER:REPORT with a non-directory pathname now + signals an error. (thanks to Pierre Mai) + * bug fix: EXPORT left symbol unexported in conflict situations. + (thanks to Michael Weber) + * bug fix: correctly handle name conflicts involving CL:NIL. + (thanks to Michael Weber) + * bug fix: RESOLVE-CONFLICT restart for name conflicts handles + conflicts arising from USEing package with conflicting symbols + correctly. (thanks to Michael Weber) + changes in sbcl-1.0.19 relative to 1.0.18: * new feature: user-customizable variable SB-EXT:*MUFFLED-WARNINGS*; warnings that go otherwise unhandled will be muffled if they are
