Subject: sbcl 1.0.38 released
Newsgroups: gmane.lisp.steel-bank.announce
Date: Friday 30th April 2010 15:55:06 UTC (over 8 years ago)
Hi,

I've just tagged CVS and put sbcl-1.0.38 up for download on Sourceforge.
The freeze was somewhat slushy this time round; I hope there won't need
to be brown paper bags handed around the development team, but please as
ever report any problems encountered with the release.

Best,

Christophe

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.
