Gmane
From: Juho Snellman <jsnell <at> iki.fi>
Subject: SBCL 1.0.58 released
Newsgroups: gmane.lisp.steel-bank.announce
Date: Monday 6th August 2012 22:16:27 UTC (over 5 years ago)
changes in sbcl-1.0.58 relative to sbcl-1.0.57:
  * enhancement: implicit generic function warnings now specify the package
    in which the new generic function is being created.
  * enhancement: SB-EXT:ATOMIC-UPDATE makes it easy to perform
non-destructive
    updates of CAS-able places (similar to Clojure's swap!).
  * enhancement: run-program no longer decodes and re-encodes environment
when
    :environment argument is not provided. (lp#985904)
  * enhancement: errors during compiler-macro expansion no longer cause
    runtime errors, only a compile-time warning, otherwise behaving as if
    the compiler macro had declined to expand.
  * optimization: On x86-64, code alignment of block headers is done with
    multi-byte NOPs now instead of repetitions of the single-byte NOP.
  * optimization: MAP-INTO is substantially faster when the target sequence
is
    of unknown type; mapping into lists is no longer O(N^2). (thanks to
James
    M. Lawrence)
  * optimization: the compiler no longer heap-conses to check exits in
cases
    where the exit function is dynamic extent, or when it can prove the
exit
    function cannot escape.
  * optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of unknown
    element type, and vectors that aren't SIMPLE-ARRAYs.
  * optimization: CL:SORT and CL:STABLE-SORT are more efficient in
execution
    speed (around 1/3 the time in some cases), and a little better in terms
of
    comparison calls. (Thanks to Takeru Ohta)
  * bug fix: On SPARC, a limitation on the number of code constants
emittable
    by the compiler has been lifted, allowing certain long functions to
    compiled and assembled which had previously been unsupported; fixes
    cl-bench on this ISA (lp#1008996).
  * bug fix: potential for infinite recursion during compilation of CLOS
slot
    typechecks when dependency graph had loops. (lp#1001799)
  * bug fix: error forms reported with some program-errors were not escaped
    properly.
  * bug fix: functions from EVAL are now on more equal footing with
functions
    from COMPILE. (lp#1000783, lp#851170, lp#922408)
  * bug fix: ENSURE-GENERIC-METHOD-COMBINATION accepts method combination
    objects as its :METHOD-COMBINATION argument, not just lists designating
    method combinations. (lp#936513)
  * bug fix: run-program no longer unconditionally uses /tmp/ for temporary
    files. (lp#968837).
  * bug fix: restore build on solaris/sparc. (lp#1008506)
  * bug fix: an issue with LDB in the PowerPC backend has been resolved;
    this fixes an issue found with cl-postgres (thanks to Tomas Hlavaty).
  * bug fix: compiler-macro lambda-lists specifying non-keyword symbols
    as keyword arguments no longer accidentally match unevaluated symbols
    against them.
  * bug fix: FORMAT used to loop infinitely in some cases when a COLINC
    parameter was zero, now it signals an error. (lp#905817, fixed since
    1.0.56.19)
  * bug fix: run-program with :pty t no longer makes the pty as the
process's
    controling terminal.
