  1. @nikodemus NEWS editing

    nikodemus committed
     * Hash-table functions aren't quite interrupt safe yet, aka brutal honesty.
     * Missing dots.

  1. make -sb-unicode builds work again

    Nathan Froyd committed
    	* SB!VM:COMPLEX-CHARACTER-STRING-WIDETAG is not bound when #!-sb-unicode

  1. @jsnell rewrite source that mixed quasiquotes and circular lists

    jsnell committed
             * CLisp didn't like the combination, use a macrolet instead
             * Patch by Luis Oliveira
  2. turn mach-exception-handler on for macos/x86 and x86_64

    Cyrus Harmon committed
     * have add mach-exception-handler to the features by
       default. This gets around the CrashReporter problems and enables
       debugging of SBCL processes with GDB.

  1. fix doc/ if "make" command is not GNU make.

    NIIMI Satoshi committed
    First build problem found by James Knight's BuildBot. :-)
  2. @nikodemus refactoring FILE-POSITION on FD-STREAMS, some cleanups

    nikodemus committed
     * Make the underlying FILE-POSITION on FD-STREAMs interrupt-safe.
       This is not enough to make FILE-POSITION on FD-STREAMs interrupt
       safe, as the ANSI-STREAM layer is not -- or at least I doesn't look
       like it to me.
     * Split FD-STREAM-FILE-POSITION into two parts for easier reading,
       and make the error behaviour more ANSI compliant.
       one-stop-shopping implementation of finish-output for FD-STREAMs.
     * New function: FD-STREAM-OUTPUT-FINISHED-P, which returns false if
       there is any pending output on the stream.
     * Add comments explaining why certain VECTOR-SAP usages are safe
       without pinning the vector -- at least on x86oids.
     * Instead of (IF #-WIN32 P #+WIN32 T #-WIN32 THEN #+WIN32 ELSE),
       let us use #-WIN32 ELSE #+WIN32 (IF P THEN ELSE)...
  3. @jsnell remove clisp from the list of working build hosts

    jsnell committed
             * It's not like it's actually worked for anyone in ages, but
               people keep trying to use it...
  4. @jsnell don't mutate constant strings in genesis

    jsnell committed
             * CLisp rightfully complains about this when used as a build host
  5. @jsnell fix build with OpenMCL as the host

    jsnell committed
             * OpenMCL doesn't do the right thing with #+foo #+foo bar bar
             * An invalid slot type declaration
Commits on Apr 18, 2007
  1. @nikodemus SB-SYS and stream cleanups

    nikodemus committed
     * Factor out looping on SERVE-ALL-EVENTS to FINISH-FD-STREAM-OUTPUT.
     * Make IO-TIMEOUT a subclass of TIMEOUT.
     * Remove spurious SB!SYS: prefixes from src/code/stream.lisp and
     * Delete stale symbols ALLOCATE-SYSTEM-MEMORY-AT, C-PROCEDURE,
       WITH-ENABLED-INTERRUPTS from SB-SYS. (Also delete commented out
       implementation of W-E-I in target-signal.lisp.)
  2. @nikodemus new STRING-OUTPUT-STREAM implementation

    nikodemus committed
     * Instead of copying the output string each time we need to expand
       it, maintain a chain of buffers. For large inputs the improvement
       is vast, for small inputs the performance characteristics are
       essentially the same. One the average seems to cons about 30% less.
  3. @jsnell gray streams manual fixes

    jsnell committed
             * From Richard Kreuter
  4. @jsnell fix big-endian build

    jsnell committed
             * Reported by Harald Hanche-Olsen
Commits on Apr 17, 2007
  1. Win32 build fix

    lisphacker committed
      * Win32 doesn't do sigaltstack, and thus has no SIGSTKSZ.
  2. @jsnell oops, missed one case in the HAIRY-DATA-VECTOR-REF changes

    jsnell committed
            * SIMPLE-STRING is a special case in EXTRACT-UPGRADED-ELEMENT-TYPE
  3. @nikodemus small genesis cleanups

    nikodemus committed
     * Factor most of the logic to munge lisp-names to C-names into C-NAME
       and C-SYMBOL-NAME.
       Also translate #\/ to #\_, fixing duplicate definition warnings for
  4. @rudi self-announcement

    rudi committed
        * patch by Yaroslav Kavenchuk
  5. @jsnell backtrace_from_fp

    jsnell committed
            * Split the ldb x86oid backtrace into two parts (backtrace and
              backtrace_from_fp), to make debugging e.g. thread deadlocks
              from gdb easier. For example: call backtrace_from_fp($rbp, 10)
  6. @jsnell faster generic array access

    jsnell committed
            * Replace the typecase-based HAIRY-DATA-VECTOR-* with a table-driven
              dispatch on widetags
            * Move bounds checking of one-dimension AREFs into HAIRY-DATA-VECTOR-*
              from the caller, so that we can avoid doing a full ARRAY-DIMENSION
              in the common case.
            * 3-5x speedup on generic array accesses

  1. @nikodemus revert test changes

    nikodemus committed
     ECHERRYPICK from commit
  2. @nikodemus revert changes to ROOM

    nikodemus committed
     * Cleaned up version conses too much.
     * Record the bug .89 was supposed to fix.
Commits on Apr 14, 2007
  1. @nikodemus ROOM cleanups & type-declaration fixes

    nikodemus committed
     * Eliminate TRULY-THE and THE from src/code/room.lisp.
     * Byte-counts don't necessarily fit into fixnums, so remove some
       of the fixnum declarations (reported by Faré on sbcl-devel.)
     * Test-case.
  2. x86 assembly-routine cleanups

    lisphacker committed
      * More uses of make-ea-for-vector-data.
      * More uses of make-ea-for-object-slot.
  3. @jsnell better EQUALP hash function for arrays

    jsnell committed
            * Hashing on just the first 4 elements makes EQUALP tables essentially
              useless for many kinds of data due to collisions. Hash all the
            * Optimize a couple of other cases that are probably common
              (u-b 8 vectors, fixnum vectors).
            * Change EQUALP-HASH to punt to EQ-HASH when appropriate
  4. @nikodemus correct type declaration for SAP+

    nikodemus committed
     * The OFFSET argument is a (SIGNED-BYTE #.N-WORD-BITS), not a FIXNUM.
  5. @nikodemus small PCL cleanups and thread-safety notes

    nikodemus committed
       equivalent to LAYOUT-CLOS-HASH. Use only the latter for easier
     * *PREVIOUS-NWRAPPERS* is protected by the PCL lock, so ok.
     * The whole of dlisp2.lisp is currently dead code.
  6. @jsnell better EQUAL hash-tables, revert (non-compliant S…

    jsnell committed
            * The value of SXHASH on non-string/bitvector arrays should not
              change when the contents of the array change (clhs sxhash,
              clhs So the commit in is invalid.
            * But luckily nothing requires us to use SXHASH for our own
              tables. Change the definition of EQUAL-HASH to punt to EQ-HASH
              for data types where EQUAL == EQL
Commits on Apr 13, 2007
  1. @jsnell fix SXHASH for bignums

    jsnell committed
            * (logAND x (ash x -7)) doesn't give a very good hash...
            * Reported by Far� Rideau on #lisp
  2. more x86 backend cleanups

    lisphacker committed
      * optimized callback code slightly (use load-symbol-value (one
        instruction) instead of two discrete instructions)
      * cleaned up pseudo-atomic by adding an optional width to
  3. more x86 backend cleanups

    lisphacker committed
      * make-ea-for-vector-data macro and use where appropriate.
  4. @nikodemus make ADJUST-ARRAY interrupt-safe

    nikodemus committed
     * WITHOUT-INTERRUPTS while using the temp-vector that is also bound
       to the thread-local *ZAP-ARRAY-DATA-TEMP*, so that interrupt handlers
       calling ADJUST-ARRAY cannot stomp on the data.
       Also zero out the temp-vector immediately, and be a bit more sensible
       about filling it.
     * STABLE-SORT has been audited for interrupt-safety vrt. its cached
       temporary vector, and is already OK.
     * Squeeze a mighty 1050 words out of the core by using empty vectors
       for both of the above to start with.
  5. @nikodemus remove lock from *descriptor-handlers*

    nikodemus committed
     * Each thread binds it, so no locking required. WITHOUT-INTERRUPTS still
       needed, however.

    jsnell committed
    … core
            * Also shrink the table if sufficiently many symbols are uninterned
              from the package
    	* Shrinks the core by 800k
