In some contrived situations, + this could lead to wrong results in mixed real/complex float arithmetic. + * bug fix: Fix function/macro redefinition warnings when building with + clisp. (lp#576787, thanks to Josh Elsasser) + +changes in sbcl-1.0.38 relative to sbcl-1.0.37: + * incompatible change: Thread names are now restricted to SIMPLE-STRINGs + like for any other thread-related datastructure, MUTEX, etc. (lp#547095) + * deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY + contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE. + * deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of + SB-THREAD:GRAB-MUTEX. + * new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to + contain additional data structures and tools for concurrent programming; + at the moment it contains a lock-free queue, and a lock-free mailbox + implementation. + * new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated + GET-MUTEX but takes &key rather than &optional parameters. Also added + :TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and + BSD. + * new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of + SB-THREAD:WAIT-ON-SEMAPHORE. + * new feature: SB-EXT:ATOMIC-DECF has been added as a companion to + SB-EXT:ATOMIC-INCF. + * new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT + conditions to defer the deadline for forever. + * enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are + now bivalent. + * enhancement: errors from NO-APPLICABLE-METHOD and + NO-PRIMARY-METHOD now have a RETRY restart available to retry the + generic function call. + * enhancement: SB-BSD-SOCKET improvements + ** sockets and socket streams now have a more informative printed + representation based on the corresponding SOCKET-NAME and + SOCKET-PEERNAME. + ** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option. + (lp#540413) + ** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to + CL:CLOSE when appropriate, and no longer disassociates the stream + from the socket if close failed. (lp#543951) + * improvements to the instrumenting profiler + ** new feature: report per-function GC overhead. (thanks to John Fremlin) + ** optimization: counters no longer use locks for the overflow mode. + ** bug fix: whenever a profiling counter wrapped into overflow mode, it + incurred an off-by-one miscount. + * enhancement: improved MAKE-HASH-TABLE documentation (lp#543473) + * enhancement: improved DEFMETHOD pretty-printing. + * enhancement: perform range reduction when arguments are too large for + x87's transcendentals (instead of returning 0). (lp#327192) + * enhancement: eliminate some spurious TYPE-WARNINGs. Should help with + some of CL-PPCRE's macros. (lp#570079) + * enhancement: our machine code is slightly less hostile to valgrind on + x86-64. + * enhancement: up-to-date versions of NetBSD-current are supported. (Thanks + to Robert Swindells and Aleksej Saushev) + * bug fix: correct restart text for the continuable error in MAKE-PACKAGE. + * bug fix: a rare case of startup-time page table corruption. + * bug fix: a semaphore with multiple waiters and some of them unwinding due + to timeouts could be left in an inconsistent state. + * bug fix: fix typo in "Reporting Bugs" section of the manual (lp#520366) + * bug fix: misoptimization of multiplication by one in + (SB-C::FLOAT-ACCURACY 0) policies. + * bug fix: miscounts in SB-PROFILE. + * bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and + CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait / + condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking + up itself" (March 2010) for further details. + * bug fix: allow forward FIND and POSITION on lists to elide checking :END + against length of the list if the element is found before the specified + END is reached. (thanks to Alec Berryman, lp#554385) + * bug fix: errors signalled during package graph modification no longer + block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072) + * bug fix: SB-POSIX build was broken when SBCL was compiled without the + :SB-DOC feature. (lp#552564) + * bug fix: SB-INTROSPECT build issues on GENGC/PPC. (lp#490490) + * bug fix: more robust runtime executable path detection. (lp#375549) + * bug fix: GCD always returns positive values. (lp#413680) + * bug fix: Converting division to multiplication by reciprocal handles + denormals. + * bug fix: We were too eager in eliding range reduction tests on x87. + The maximal magnitude is 2^63, not 2^64. + * bug fix: Transforms for TRUNCATE don't die when the result is completely + ignored anymore. + * bug fix: Maybe restore buildability on Alpha. + * bug fix: READ-BYTE isn't inline anymore, fixing weird streams failures. + (lp#569404) + * bug fix: RANDOM-STATE can be printed readably again. + * bug fix: Unreadable objects were sometimes printed like #<\nFoo>. + * bug fix: Using EQL with non-constant values of constant type (e.g. EQL + types) could result in type mismatches during compilation. + +changes in sbcl-1.0.37 relative to sbcl-1.0.36: + * enhancement: Backtrace from THROW to uncaught tag on x86oids now shows + stack frame thrown from. + * enhancement: WITH-COMPILATION-UNIT :POLICY allows restricting changes to + compiler optimization qualities inside dynamic extent of its body. + * enhancement: LOAD-LOGICAL-PATHNAME-TRANSLATIONS can be used to load + translations from SYS:SITE;.TRANSLATIONS.NEWEST (thanks to Michael + Weber) + * optimization: SLOT-VALUE and (SETF SLOT-VALUE) take advantage of + constraint propgation, allowing better compilation eg. when used to + access structures with WITH-SLOTS. (lp#520366) + * optimization: the compiler is now more aware of the type of the underlying + storage vector for multidimensional simple arrays resulting in better code + for accessing such arrays. + * optimization: passing NIL as the environment argument to TYPEP no longer + inhibits optimizing it. (lp#309788) + * optimization: more efficient register usage when handling single-float + arguments on x86-64. (thanks to Lutz Euler) + * optimization: ADJUST-ARRAY and STABLE-SORT on vectors no longer use + pre-allocated temporary vectors. (lp#496249) + * bug fix: Fix compiler error involving MAKE-ARRAY and IF forms + in :INITIAL-CONTENTS. (lp#523612) + * bug fix: FUNCTION-LAMBDA-EXPRESSION lost declarations from interpreted + functions. (lp#524707) + * bug fix: bogus style warnings from certain (SETF SLOT-VALUE) and + WITH-SLOTS usages during compilation. + * bug fix: SB-C::CLASS-INFO now prints correctly. (lp#514762) + * enhancement: Can now build with ud2 instead of int3 as trap instruction on + all x86oid platforms with :UD2-BREAKPOINTS target feature. + * bug fix: Breakpoints now work when using ud2 instead of int3 as trap + instruction (tested on x86oid linux with ud2-breakpoints). + * bug fix: slam.sh now works on win32. + * bug fix: better differences of numeric types. (lp#309124) + * bug fix: arrays declared intersection and union types can have their + upgraded element type derived. (lp#316078) + * bug fix: SB-SPROF allocation profiling for all threads failed to profile + threads started during profiling. (lp#472499) + * bug fix: SB-INTROSPECT test failure when building without SB-EVAL feature. + (lp#535658) + * bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take + SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337) + * bug fix: Comma inside a backquoted array or structure resulted in nonsense + values instead of signaling an error. (lp#309093) + * bug fix: Spurious unused variable warning in a DEFSTRUCT edge case. + (lp#528807) + * bug fix: More consistent warnings and notes for ignored DYNAMIC-EXTENT + declarations (lp#497321) + * bug fix: FIND and POSITION on lists did not check sequence bounds properly + and failed to detect circular lists (lp#452008) + * bug fix: leakage from ~/.asdf-install into the ASDf-INSTALL contrib build + (lp#538974) + * bug fix: LOOP OF-TYPE VECTOR compile-time error. (lp#540186) + * bug fix: SIGNAL SB-SYS:INTERACTIVE-INTERRUPT before entering the debugger + due to it, so that handlers can run. + * bug fix: reparsing undefined types if they have become defined since + parsing. (lp#309128) + * bug fix: missing &REST type in a proclamation for a function with both + &REST and &KEY in lambda-list caused miscompilation (lp#458354) + * bug fix: WHO-CALLS information for source-transformed and compiler-macro + expanded calls (lp#542174) + * bug fix: more accurate WHO-MACROEXPANDS information; point into rather + than just at toplevel form. + +changes in sbcl-1.0.36 relative to sbcl-1.0.35: + * new feature: SB-EXT:TYPEXPAND-1, SB-EXT:TYPEXPAND, and + SB-EXT:TYPEXPAND-ALL behave exactly like their MACROEXPAND counterparts + but work on type specifiers. + * new feature: SB-EXT:DEFINED-TYPE-NAME-P returns whether a symbol is known + to name a type specifier. + * new feature: SB-EXT:VALID-TYPE-SPECIFIER-P returns whether a given type + specifier is valid where "valid" basically means "would be accepted as + second argument of TYPEP". + * new feature: SB-INTROSPECT:FUNCTION-TYPE takes a function-designator and + returns the function's declared, or derived FTYPE. + * new feature: SB-POSIX now supports accessing the d_ino member of + dirent structures. (Thanks to Philipp Marek and Pierre THEIRRY) + * new feature: The function SB-EXT:SEED-RANDOM-STATE has been added to + provide for seeding a RANDOM-STATE object with user-provided data or + from the operating system's PRNG. Also, (MAKE-RANDOM-STATE T) will + attempt to initialize the returned state from the operating system's + PRNG where possible. (Thanks to Fare Rideau; launchpad bug lp#310116) + * bug fix: Fix SB-SIMPLE-STREAMS:READ-VECTOR to correctly set the + FILE-POSITION of the stream being read from. (launchpad bug lp#491087) + * bug fix: Fix grammar and style issues for the docstrings of + printer-related variables and functions. (Thanks to mon_key; launchpad + bug lp#518696) + * bug fix: Fix compilation on chenygc platforms. Thanks to Larry Valkama and + Bruce O'Neel. + * bug fix: SB-THREAD:CONDITION-WAIT sometimes signaled a deadline twice + in a row even though a handler defered the deadline long into the + future. (lp#512914) + * bug fix: A deadline handler was run without interrupts enabled for a + deadline signaled within SB-THREAD:CONDITION-WAIT. That could result + in infinitely spinning, non-killable threads. + * bug fix: Backtrace from internal-errors on x86-64 os x was truncated + before reaching the erring stack frame. + * bug fix: Fix type derivation for EXPT when raising a fixnum to a + real power. (launchpad bug lp#525949) + * bug fix: Fix SB-EXT:GENERATION-* accessors for generations > 0 on + GENCGC platforms. (launchpad bug lp#529014) + * bug fix: More robust checks for invalid DEFMETHOD argument specializers. + (launchpad bug lp#525916) + * bug fix: Fix building on Darwin when sysctl is not in the user's PATH. + (Thanks to Robert Goldman) + changes in sbcl-1.0.35 relative to sbcl-1.0.34: * optimization: ROUND with a single single-float or double-float argument is properly inlined when possible.
