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
