See: SB-EXT:*USERINIT-PATHNAME-FUNCTION* + and SB-EXT:*SYSINIT-PATHNAME-FUNCTION*. + * bug fix: bound derivation for floating point operations is now more + careful about rounding possibly closing open bounds. (lp#793771) + * bug fix: SB-POSIX:SYSCALL-ERROR's argument is now optional. (accidental + backwards incompatible change in 1.0.48.27) + * bug fix: occasional debugger errors in when a type-error occured in a + function with dynamic-extent &rest list. + * bug fix: &optional and &key supplied-p arguments in DEFSTRUCT + boa-construtors can be used to initialized structure slots. + * bug fix: FMAKUNBOUND removes the MACRO-FUNCTION, should one exist. + (lp#795705, regression) + +changes in sbcl-1.0.49 relative to sbcl-1.0.48: + * minor incompatible change: WITH-LOCKED-HASH-TABLE no longer disables + interrupts for its body. + * enhancement: source locations are now available for files loaded as + source, compile-time-too evaluation, and initialization files. + * enhancement: WITH-COMPILATION-UNIT :SOURCE-NAMESTRING allows providing + virtual source-file information, eg. overriding input-file of COMPILE-FILE + when a temporary file is used for compilation. + * enhancement: ASDF has been updated to version 2.015.3. + * enhancement: backtraces involving frames from the default evaluator are + more readable. + * enhancement: RUN-PROGRAM works with user-defined binary input and output + streams. + * enhancement: more informative compile-time warnings and runtime errors for + type-errors detected at compile-time. + * enhancement: deadlock detection for mutexes and spinlocks. + * enhancement: dynamic-extent for &rest lists stack allocate only their + spines, not their argumets. While portable code should not rely on this, + particularly in combination with inlining, it should make dynamic-extent + easier to use safely. + * enhancement: SB-POSIX improvements: + ** WNOHANG and WUNTRACED are exported. + ** SYSCALL-ERROR now also provides the name of the failing system call. + * enhancement: --script improvements: + ** errors on standard input, output, and error streams are handled and + cause scripts to exit silently, making them easier to use in shell + pipelines. + ** backtraces from scripts now go to standard error instead of the + terminal even if one is available. + ** --script can be an argument, causing the script to be loaded from + standard input. + * enhancement: MAKE-ALIEN-STRING provides an easy way to transport lisp + strings to foreign memory. + * enhancement: (SETF GC-LOGFILE) allows logging garbage collections to + a file, making it easier to understand heap dynamics. + * optimization: using a &REST argument only in APPLY or VALUES-LIST calls + allows the compiler to automatically elide rest-list allocation so long as + the call sites are in functions that the compiler knows cannot escape. + (lp#504575) + * optimization: CALL-NEXT-METHOD using explicit arguments is faster, + especially in safe code when none of the required arguments have changed + their identities. + * bug fix: blocking reads from FIFOs created by RUN-PROGRAM were + uninterruptible, as well as blocking reads from socket streams created + with for which :SERVE-EVENTS NIL. (regression from 1.0.42.43) + * bug fix: SET-SYNTAX-FROM-CHAR now removes dispatch-macro character syntax + from the to-char if the from-char is not a dispatch-macro character. + * bug fix: references to undefined variables in function calls that are + optimized away now signal a runtime error. (lp#722734) + * bug fix: miscompilation of MULTIPLE-VALUE-CALL when asserting derived + types from a function defined in the same file. (regression from + 1.0.43.57) + * bug fix: TRULY-THE forms are now macroexpandable and setf-expandable. + (lp#771673) + * bug fix: spurious errors during QUIT when standard streams were closed. + +changes in sbcl-1.0.48 relative to sbcl-1.0.47: + * incompatible change: SB!KERNEL:INSTANCE-LAMBDA, deprecated for over five + years, is now no longer supported. * enhancement: read() and write() have been added to SB-POSIX. * enhancement: types of DEFSTRUCT constructors are proclaimed more accurately, allowing better typechecking of call-sites. - * incompatible change: SB!KERNEL:INSTANCE-LAMBDA, deprecated for over five - years, is now no longer supported. + * enhancement: errors during compile-time-too processing (i.e. EVAL-WHEN) + are no longer caught. (reverted to pre 1.0.34 behaviour) * optimization: slightly faster ISQRT. (lp#713343) + * bug fix: better support for Solaris /bin/sh in sh-based tests. * bug fix: TRACE behaves better when attempting to trace undefined functions. (lp#740717) + * bug fix: missed optimizations for (FUNCALL (LAMBDA ...) ...) in comparison + to (FUNCALL #'(LAMBDA ...) ...). + * bug fix: ((LAMBDA ...) ...) forms with invalid argument counts resulted in + a compile-time error. (lp#720382) + * bug fix: forms such as (FUNCALL (FUNCTION NAME OOPS) ...) were compiled + without complaints. + * bug fix: less verbose source forms for functions from EVAL. (lp#747485) + * bug fix: sense of SLOT-BOUNDP-USING-CLASS was inverted in a MAKE-INSTANCE + optimization. (regression from 1.0.45.18/1.0.46.15) + * bug fix: package locks did not protects against compile-time side-effects + of DEFUN. (lp#675584) + * bug fix: --dynamic-space-size argument is validated more carefully. + (lp#721457) + * bug fix: memory fault from printing a malformed simple-condition. + (lp#705690) + * bug fix: redefining classes so that slot-definition classes change now + engages the obsolete instance protocol. (lp#766271) + * bug fix: constant improper lists could break source coverage recording. + (lp#767959) + * bug fix: compiling calls to eg.
