MOP improvement: support for user-defined subclasses of
SB-MOP:SPECIALIZER has been enhanced. The experimental interface
function SB-PCL:MAKE-METHOD-SPECIALIZERS-FORM, called as part of
the expansion of DEFMETHOD, is responsible for generating a form
which creates a list of specializers when evaluated. Additional
functions SB-PCL:[UN]PARSE-SPECIALIZER-USING-CLASS provide
debugging and introspective support.
minor incompatible change: the (unsupported) spinlock interface
has changed: free spinlock now has the value NIL, and a held spinlock
has the owning thread as its value.
enhancement: WITHOUT-INTERRUPTS now binds ALLOW-WITH-INTERRUPTS and
WITH-LOCAL-INTERRUPTS as local macros. Refer to documentation string
enhancement: name of a socket-stream is now "a socket" instead of
"a constant string".
enhancement: SB-POSIX now supports lockf(). (Thanks to Zach Beane.)
enhancement: SB-POSIX now supports getcwd(). (Thanks to Tassilo Horn.)
enhancement: SB-INTROSPECT:FUNCTION-ARGLIST shows nicer argument lists
for generic functions. (Thanks to Tobias C. Rittweiler)
optimization: bignum printing speed has been improved by 20-40%
(depending on the bignum size.)
bug fix: WITH-MUTEX and WITH-RECURSIVE-LOCK are now interrupt safe
bug fix: the cache used by the CLOS to store precomputed effective
methods, slot offsets, and constant return values is now thread and
bug fix: generic function dispatch function updating is now thread
and interrupt safe (in the sense that the known issues have been
bug fix: ADD/REMOVE-METHOD is now thread and interrupt safe.
bug fix: interning EQL-specializers is now thread and interrupt safe.
bug fix: asdf systems with dependencies to the SB-POSIX or
SB-BSD-SOCKETS contribs can be loaded with :FORCE T.
bug fix: interrupt safety of applicable method computation has been
New in version 1.0.6
new contrib: sb-cover, an experimental code coverage tool, is included
as a contrib module.
optimization: STRING-TO-OCTETS for unibyte encodings and UTF-8 is
optimization: calls of the form (AREF FOO (+ INDEX <constant>)) now
produce more efficient code on x86-64 if the compiler can determine
that (+ INDEX <constant>) does not require a bounds check and FOO
has an element type at least 8 bits wide.
enhancement: a new, experimental synchronous timeout facility is
provided. Refer to SB-SYS:WITH-DEADLINE for details.
enhancement: when a symbol name conflict error arises, the
conflicting symbols are always printed with a package prefix.
(thanks to Kevin Reid)
enhancement: stepping is now once again supported on the SPARC and
MIPS platforms. (It is also now more likely to work on CheneyGC
builds on the PPC.)
enhancement: sb-sprof can now also track and report accurate call
bug fixes: the treatment of non-standard subclasses of
SB-MOP:SPECIALIZER is more correct.
incompatible change: PURIFY no longer copies the data from the
dynamic space into the static and read-only spaces on platforms
that use the generational garbage collector
bug fix: GETHASH, (SETF GETHASH), CLRHASH and REMHASH are now
bug fix: GC race condition occasionally resulting in crashes with
the error message "SIG_STOP_FOR_GC blocked at a bad place" has been
bug fix: &ENVIRONMENT variables in macro lambda lists can now be
bug fix: DEFSETF lambda lists without &ENVIRONMENT no longer cause
a STYLE-WARNING to be signalled (regression from 1.0.4.)
bug fix: an asynchronous interrupt could previously leave the
system running with GC inhibited.
bug fix: a DECLARE form evaluated at top-level now causes an error
rather than silently (or verbosely) returning NIL.
bug fix: trying to dissassemble functions compiled at high DEBUG could
result in a error being signalled due to source form lookup errors.
