+2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
+
+ * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
+
+ (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
+ pointer trickery.
+
+ (SET_DYNL_HANDLE): Added.
+
+ (scm_dynamic_object_p): Simplified.

+2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * scmsigs.c (orig_handlers) [HAVE_SIGACTION]: Fix declaration to

+ (scm_divbigbig, scm_divbigint): Don't return zero any more to
+ indicate that a division has a remainder, return SCM_UNDEFINED

+ change in behaviour the functions are static now. Thus, if
+ surprisingly there are users of these functions they will at least
+ get alarmed.
+
+ * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
+ that already have a clean dispatch order. Note: SCM_BIGDIG is
+ always defined.
+
+ * numbers.c (scm_inexact_p): Simplified.
+
+ * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
+ scm_product, scm_num2dbl, scm_angle): Reordered dispatch
+ sequence, thereby fixing some comparisons of SCM values with
+ integer constants.
+
+ * numbers.c (scm_divide): Division by zero of inums leads to an
+ error now. (Formerly, an infinite number was returned.)
+
+ Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
+ if a division has a remainder.

+
+2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
+

+2000-04-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * iselect.c (add_fd_sets): Insert empty statement after label.
+ (Thanks to Tim Mooney.)
+
+2000-04-03 Michael Livshin <mlivshin@bigfoot.com>
+
+ * guardians.c (scm_guardian_zombify): mark all zombies in a
+ separate loop after processing all the currently known live
+ guardians, so as to not introduce order dependencies (thanks to
+ Gary Houston). note that the order problems are still there if
+ some guardians are themselves zombies, but that's a sick case that
+ I'm not going to worry about.
+ also, make another outer loop to process zombified
+ guardians (which are uncovered while marking zombies).

+
+2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>

+
+ * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
+ coop_mother, coop_child): New variables.
+ (mother): New function.
+ (coop_create): New thread spawning mechanism which uses a "mother

+
+ * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
+ scm_make_mutex, scm_make_condition_variable): Cast data to
+ scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
+
+ * coop.c (coop_create): Set `specific' field, not `data' to NULL.
+
+2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
+ SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
+ data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
+
+ Note that this implies that smob data has always to be passed as
+ values of type scm_bits_t.
+
+2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
+
+ * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
+ for scm_tc16_thread. As the current COOP threads are written, GC

+ scm_gc_heap_lock is true.
+
+ * coop.c (coop_finish): New function. Called at exit.

+ SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
+ continuation data.
+
+ * continuations.c (scm_make_cont), init.c (start_stack),
+ root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
+ SCM_SETJMPBUF.
+
+2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
+ of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
+
+ (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
+ to access the char * field of strings and symbols.
+
+2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
+ the type entry of a new cell. Added a comment about things to
+ remember when updating the list of free cells.
+
+ (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
+ entry of a cell.
+
+2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
+ SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
+ with strict type checking enabled these macros will only work if
+ given valid SCM parameters.
+
+ (SCM_GCCDR): Moved to tags.h.
+
+ * tags.h (SCM_GCCDR): Moved here from pairs.h.
+
+2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
+
+ * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,

+ SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
+ SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
+ SCM_NEWCELL2): Moved to gc.h.
+
+ (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
+ SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
+ be changed, though, since the macros are not only pair related.
+
+ (SCMPTR): Deleted.
+
+ * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
+ SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
+ SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,

+ tags.h and pairs.h.
+
+2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
+ activates strict compile time type checking for variables of
+ type SCM.
+ (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
+ SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
+ (SCM_EQ_P): Defined as a macro equivalent for eq?.
+
+2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * tags.h (SCM_POINTERS_MUNGED): Removed.
+
+ * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
+ SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
+
+2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
+ SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
+ SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
+ cell entries.
+ (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
+
+ * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
+ newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
+
+2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * tags.h: Disabled definition of SCM_VOIDP_TEST.
+
+ Defining SCM as void * introduces problems which haven't been
+ handled yet. Developers who work with these issues can enable it
+ in their working copies.
+
+ Disabling this definition exposes a set of newly introduced and
+ older misuses of types which causes warning messages during
+ compilation. We'll fix this successively.
+
+ * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
+ in order to obtain a value of type SCM.
+ (scm_cellp): Updated with new changes to scm_mark_locations.
+
+ * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
+
+ * continuations.c (scm_make_cont): Removed cast of size_t into
+ long.
+
+ * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
+
+2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
+ shifting, not constant. Thanks to Dale P. Smith.
+
+ * numbers.c (scm_sum, scm_difference): Don't test a SCM value
+ for being less than zero. Decode it to a C value first. Again,
+ thank you Dale.
+
+2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
+ non scheme values. If raw data is stored in SCM variables, it has
+ to be accessed using SCM_UNPACK until a better solution is found.
+
+2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of

+
+ * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
+
+ * async.c, __scm.h: Removed lots of the old async click logic. It
+ is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
+ __scm.h. Let's try this out and dump the old code after the
+ threads reorganization.
+ (set-tick-rate, set-switch-rate): Conditionally removed.
+
+2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
+ made SCM values into pointers. This turned an arithmetic
+ computation of the address of the vcell into a pointer-arithmetic
+ one, thereby screwing up marking of structs.
+ Bugfix 2: Removed incompletely introduced loop variable `j' used
+ when protecting the tail array of a struct.
+
+2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
+
+2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * symbols.h, symbols.c (scm_strhash): Declare the string
+ parameter as constant, since it is not modified.
+
+ * symbols.c (scm_intern_obarray_soft,
+ scm_sysintern0_no_module_lookup): Can now pass constant strings
+ to scm_strhash without need for casting.
+
+2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
+ values to pointers. Use SCM2PTR instead.
+
+2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
+ results of SCM_INUM.
+
+2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
+
+ * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
+ GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
+ GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
+
+ * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
+ min_yield_fraction, min_yield, adjust_min_yield): Renamed from
+ SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
+ gc_trigger, adjust_gc_trigger.
+
+ * gc.c (alloc_some_heap): Further improvement of minimal heap size
+ prediction.
+ (SCM_MAX): New macro.
+ (scm_freelist_t): New field: collected_1. Previous amount of
+ collected cells.
+ (gc_sweep_freelist_finish): Trigger based on two last values of
+ freelist->collected to avoid unnecessary allocation due to
+ temporary peaks.
+ (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
+ Adjusted to 45000 cells, 40% and 40%. Gives quick startup
+ without extra heap allocation.
+
+2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
+ already be a C value. No need to unpack it.
+
+ * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
+ if we know it fits into an inum.
+
+ * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
+ field of long values. In contrast, SCM_VELTS accesses a field of
+ SCM values.
+
2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
etc.
+ (scm_gc_yield_1): New variable: Holds previous yield. Used to
+ make better judgements.
+ (gc_sweep_freelist_finish): Inserted explanation of use of
+ gc_trigger.
* print.h, stacks.h, options.c, options.h: Changed C++
commentaries to C.
