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) + * 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 + interrupt safe. + * bug fix: GC race condition occasionally resulting in crashes with + the error message "SIG_STOP_FOR_GC blocked at a bad place" has been + fixed. + * bug fix: &ENVIRONMENT variables in macro lambda lists can now be + declared ignored. + * 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. + +changes in sbcl-1.0.5 relative to sbcl-1.0.4: + * incompatible change: removed writer methods for host-ent-name, + host-ent-addresses -- changing the values did not update the DNS + information anyway. + * minor incompatible change: changed experimental JOIN-THREAD interface + * documentation: the manual now lists reader and writer methods + in class slot documentation sections. (thanks to Richard M Kreuter) + * documentation: unwinding from asyncronous events has been + documented as unsafe. + * documentation: SB-SYS:WITHOUT-GCING has been documented as unsafe + in multithreaded application code. + * optimization: GET-INTERNAL-REAL-TIME has been optimized on POSIX + platforms. (thanks to James Anderson for the optimization hint) + * optimization: REPLACE, SUBSEQ, and COPY-SEQ are now optimized in + more cases. + * optimization: STRING-{EQUAL,LESSP,GREATER-P} and their NOT- + variants no longer cons. + * optimization: Direct calls to CHAR-{EQUAL,LESSP,GREATERP} and + their NOT- variants no longer cons. + * optimization: EQUAL hash tables no longer use SXHASH for objects + of all data types, but instead use an EQL hash for types for which + EQUAL is the same as EQL. + * optimization: the non-inlined generic versions of AREF and (SETF AREF) + are significantly faster. + * optimization: new STRING-OUTPUT-STREAM implementation is much + faster for large outputs and conses 30% less on average. + * enhancement: XREF information is now collected for references made + to global variables using SYMBOL-VALUE and a constant argument. + * enhancement: SIGINT now causes a specific condition + SB-SYS:INTERACTIVE-INTERRUPT to be signalled. + * bug fix: FILE-POSITION used to signal an error in some cases where + ANSI requires it to return NIL. + * bug fix: ADJUST-ARRAY is now interrupt-safe. + * bug fix: adding and removing fd-handlers is now interrupt-safe. + * bug fix: inlined calls to C now ensure 16byte stack alignment on + x86/Darwin. + * bug fix: bad type declaration in the CLOS implementation has + been fixed. (reported by James Anderson) + * bug fix: incorrect ROOM reporting on x86-64 has been fixed. + (thanks to Lutz Euler) + * bug fix: DEFSETF now allows &ENVIRONMENT and disallows &AUX as + required by the CLHS. (reported by Samium Gromoff) + * bug fix: dead unbound variable references now signal an error. + (reported by Marco Monteiro) + * bug fix: / with an unused value was being deleted in safe code. + (thanks to Marco Monteiro and Kevin Reid) + * bug fix: number of characters that can be written onto a single + line in a file is unlimited. + * bug fix: some GC deadlocks caused by asynchronous interrupts have + been fixed by inhibiting interrupts for when GC is disbled. + * bug fix: some interrupt safety issues with GETHASH, (SETF + GETHASH), CLRHASH and REMHASH have been fixed. + * bug fix: binding *BREAK-ON-SIGNALS* to a value that is not a type + specifier no longer causes infinite recursion. + * bug fix: SB-EXT:MUFFLE-CONDITIONS declarations no longer trigger a + bogus warning in DEFMETHOD bodies. (reported by Kevin Reid) + * bug fix: an &environment argument with the correct variable information + is passed to macros that are expanded during byte compilation. + (reported by Samium Gromoff) + * bug fix: a logic error was causing the hash function for bignums to + have excessive amounts of collisions. (reported by Faré Rideau) + * bug fix: modifying the contents of an array could change the return + value of SXHASH on that array, which is only allowed for strings + and bit vectors. (bug introduced in 0.9.16) + * improvement: the x86-64/darwin port now passes all tests (except + for the debugger tests) but should still be considered + experimental until this is fixed. + * improvement: a style-warning is signaled for CASE (etc) clauses with + duplicate keys. (thanks to Kevin Reid) + * improvement: macos/x86 and macos/x86-64 now use mach exception + handlers for dealing with illegal instructions (for trapping and + error handling) and memory protection violations (for GC). + changes in sbcl-1.0.4 relative to sbcl-1.0.3: * new platform: experimental support for x86-64/darwin (MacOS). * incompatible change: the thread-safe (on most platforms) getaddrinfo @@ -9,7 +103,7 @@ changes in sbcl-1.0.4 relative to sbcl-1.0.3: * change: runtimes with embedded cores (i.e. saved with :EXECUTABLE T) don't print the startup banner, but behave as if --noinform was passed as a command line argument.
