Now a single deadlock is reported exactly once. + * bug fix: interval-arithmetic division during type derivation did not + account for signed zeros. + * bug fix: compiler error when typechecking a call to a function with + non-constant keyword arguments. + * bug fix: misoptimization of TRUNCATE causing erratic behaviour. + +changes in sbcl-1.0.54 relative to sbcl-1.0.53: + * minor incompatible changes: + ** RENAME-FILE on a symbolic links used to rename the linked-to file + instead of the link. + ** DELETE-DIRECTORY on symbolic link to a directory used to delete the + directory, but now signal an error instead. Use TRUENAME to resolve the + pathname if you wish to delete the linked directory, and DELETE-FILE if + you wish to delete the + ** The internal SB-THREAD::SPINLOCK API has been deprecated, and using + symbols associated with it will trigger a compile-time warning. + * thread-related enhancements: + (This work has been funded by the SBCL Threading 2011 IndieGoGo campaign. + Many thanks to generous donors!) + ** Threading is now more reliable on non-Linux platforms. We still don't + consider threads on non-Linux platforms good enough to enable them by + default, but they're in a clearly better shape now. + ** Deadlines supported now on all platforms. + ** All blocking functions in the threading API now have a :TIMEOUT + argument. + ** Semaphore notification objects have been added to SB-THREAD. + ** SB-CONCURRENCY contrib now includes Allegro-style GATE objects. + ** SB-EXT:COMPARE-AND-SWAP has been extended to support SLOT-VALUE, + STANDARD-INSTANCE-ACCESS, and FUNCALLABLE-STANDARD-INSTANCE-ACCESS. + ** Users can now defined new places usable with SB-EXT:COMPARE-AND-SWAP + using an API anologous to defining new SETFable places. + * GC-related enhancements and bug fixes: + ** --dynamic-space-size and --control-stack-size now understand Kb, Mb, + and Gb suffixes. Default is megabytes as before. + ** on GENCGC targets, the default dynamic space size is now 512Mb for + 32-bit systems, and 1Gb for 64-bit systems. (OpenBSD/x86-64 is the only + exception, defaulting to mere 444Mb to fit under default ulimits.) The + new defaults are in place to prevent hitting swap on low-end systems. + Use build-time option --dynamic-space-size to build an SBCL with + another default, or the runtime option to adjust the size at startup: a + good size is at most equal to the amount of physical memory the system + has. + ** on GENCGC targets, nursery and generation sizes now default to 5% of + dynamic-space size. + ** on GENCGC targets, SB-KERNEL:MAKE-LISP-OBJ no longer categorically + refuses to create SIMPLE-FUN objects. + ** on 64-bit GENCGC targets, setting the nursery size above 4Gb now works. + (lp#870868) + ** on CHENEYGC targets, SB-KERNEL:MAKE-LISP-OBJ now does the same + validation of pointer objects as GENCGC does, instead of a + comparatively weak bounds-check against the heap spaces. + * SB-BSD-SOCKETS bug fixes: + ** GET-PROTOCOL-BY-NAME had a significant memory leak. + ** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS small amounts of memory on + systems with getaddrinfo(). + ** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS weren't thread or interrupt + safe outside systems with getaddrinfo(). + * enhancement: ASDF has been updated 2.019. + * enhancement: special-case TCO prevention for functions which never return + extended to untrusted types, keeping one more frame's worth of debug + information around in many cases. + * enhancement: debug-names of anonymous and local function are more + descriptive. Affects backtraces and SB-SPROF results. (lp#805100) + * enhancement: on win32, ABS of complex floats guards better against + overflows. (lp#888410) + * enhancement: RUN-PROGRAM now distinguishes exec() failing from child + process exiting with code 1. (lp#676987) + * enhancement: convenience function SET-SBCL-SOURCE-LOCATION for informing + the system where on the filesystem the SBCL sources themselves are + located. (Thanks to Zach Beane) + * enhancement: the compiler is now able to derive tighter bounds for + floating point numbers in some cases. (Thanks to Lutz Euler, lp#894498) + * bug fix: on 64-bit targets, atomic-incf/aref does index computation + correctly, even on wide-fixnum builds. (lp#887220) + * bug fix: (DIRECTORY "foo/*/*.*") did not follow symlinks in foo/ that + resolved to directories. + * bug fix: type mismatch when assigning to lexical variables no longer + result in fasl-dumping internal type objects. (lp#890750) + * bug fix: type mismatch on (SETF AREF) and function return values no + longer result in fasl-dumping internal type objects. + * bug fix: With several combinations of argument types, for example (EXPT + <(complex double)>), EXPT now uses double-precision throughout + instead of partially calculating only to single-precision.

Use the :COMPRESSION + argument to SAVE-LISP-AND-DIE to specify a compression level. + * enhancement: --[no-]merge-core-pages determines whether the runtime + hints the operating system that identical core pages between SBCL + processes should share the same physical memory. Default is to only + enable this for compressed cores. + * optimization: SLEEP no longer conses. + * optimization: *PRINT-PRETTY* no longer slows down printing of strings + or bit-vectors when using the standard pretty-print dispatch table. + * bug fix: non-function FTYPE declarations no longer cause a compiler-error. + (lp#738464) + * bug fix: compiler-errors causes by MEMBER types in conjunction with with + AREF, CHAR, etc. (lp#826971) + * bug fix: compiler-errors causes by integer arguments with composed of + multiple ranges to ARRAY-IN-BOUNDS-P.

(Use "SBCL_ARCH=x86 sh make.sh" to build.) + * enhancement: added new toplevel options --quit and --non-interactive + (lp#822712). + * enhancement: the Windows port of SBCL now builds and runs on Wine + (thanks to Anton Kovalenko). + * enhancement: more, and more correct, SSE instruction definitions on + x86-64 (thanks to Alexander Gavrilov). + * enhancement: SB-EXT:SPIN-LOOP-HINT assembles to an instruction designed + to help the processor execute spin loops, when applicable. Currently + implemented for x86 and x86-64. + * optimization: unsigned integer divisions by a constant are implemented + using multiplication (affects CEILING, FLOOR, TRUNCATE, MOD, and REM.) + * optimization: improved type-derivation for LOAD-TIME-VALUE. + * bug fix: correct RIP offset calculation in SSE comparison and shuffle + instructions. (lp#814688) + * bug fix: COERCE to unfinalized extended sequence classes now works. + (reported by Jan Moringen; lp#815155) + * bug fix: a compiler error during typecheck generation, reported by Eric + Marsden.
