+
+ this changes the Guile GC to use cards (aka "chunklets").
+ (most of the ideas and some of the code are by Greg Harvey, though
+ the code is probably unrecognizable now. the original chunklet
+ proposal, way back, is by Dale Jordan).
+
+ * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
+ SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
+ some (most) of these are probably going to be deprecated.
+
+ * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
+ locations anymore.
+ (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
+ cards and bvecs (bit-vectors).
+
+ * gc.c: (scm_default_init_heap_size_*): defined to take cards into
+ account, but keeping more or less the same values as previously.
+ added some simple helper macros.
+ (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
+ into account.

+
+ * stime.c (scm_c_get_internal_run_time): new function, same as
+ scm_get_internal_run_time but returns a long. it's used by the GC
+ for timekeeping, since with scm_get_internal_run_time there is a
+ (extremely theoretical) possibility of consing.
+ (scm_get_internal_run_time): redefined in terms of
+ scm_c_get_internal_run_time.
+
+ * stime.h: added prototype for scm_c_get_internal_run_time.

+ to init the new stats.
+ (gc_end_stats): renamed from scm_gc_end, made static, taught to

+
+ The following changes are intended to ensure that struct instances

+ * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
+ (scm_structs_to_free): New variable.
+ (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free

+
+ * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
+
+2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>

+
+2000-07-31 Gary Houston <ghouston@arglist.com>
+
+ * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined

+2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * alist.c (scm_assq_remove_x, scm_assv_remove_x,
+ scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
+ using the latter is pointless.
+
+2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
+ 'free_struct_data' to avoid confusion with stdlib's 'free'.
+
+2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
+

+
+2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
+ on the struct cell to be fully initialized.
+
+ * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
+ initialization order of the struct such that the type cell is
+ initialized last.
+
+2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * alist.c (scm_assq_remove_x, scm_assv_remove_x,

+
+2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * stime.c (scm_strftime): Recognize a return value of zero from

+
+2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * alist.c (scm_assq_remove_x, scm_assv_remove_x,
+ scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
+ equal (respectively) to the argument key, not all cells that are

+ to Neil Jerram!
+
+2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
+ (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
+ SCM values appropriately.
+
+ * modules.c (scm_standard_eval_closure): Don't pass an inum to
+ scm_makcclo, but rather a long value.
+
+2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
+ SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
+ Thanks to Han-Wen Nienhuys for the bug report.
+
+2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * root.[ch] (scm_call_catching_errors): Deprecated.

+
+2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
+

+ one element. Thanks to Bill Schottstaedt!
+
+2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
+
+ * gc.c (scm_done_free): new.
+ expanded comments about scm_done_malloc.
+
+ * gc.h: added prototype for scm_done_free
+
+2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.h (scm_take_stdin): Removed.
+
+ * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
+ scm_assert_cell_valid to allow extensions to the checking
+ functionality without need to recompile everything.
+

+ Added as conditionally compiled functions for the case that
+ SCM_DEBUG_CELL_ACCESSES is enabled.
+
+ * gc.c (debug_cells_p): Added to indicate whether compile-time
+ included cell access debugging is run-time enabled.
+
+ * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
+ being executed. Intended to be used instead of scm_gc_heap_lock
+ at most places.
+
+ * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
+ instead of scm_gc_heap_lock.
+
+ * gc.c (scm_igc): Set scm_gc_running_p to true while running.
+
+ * gc.c (scm_mark_locations): Don't mark free cells.

+2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.c (scm_mark_locations): Minimized some variable scopes and
+ simplified the code a bit.
+
+2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
+ SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
+ should not be accessed via SCM_C[AD]R. Further, using dedicated
+ macros to access free cells allows all other cell accessing macros
+ to treat acesses to free cells as errors, thus enabling better
+ error checks for cell accesses. SCM_FREE_CELL_P is supposed to
+ replace SCM_FREEP some time.
+
+ * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
+ free_list_length, scm_check_freelist, scm_debug_newcell,
+ scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
+ scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
+ cell accessors when accessing free cells.
+
+2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
+ object as const in order to make the compiler warn about code like
+ SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
+ should be used.
+
+ (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
+ as an address to a non-const object, since these macros are used
+ to allow direct write access to objects.
+
+2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
+ given hash table has no slots.
+
+2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.c (policy_on_error): Added in order to allow alloc_some_heap
+ to react to malloc failures in a context dependent way.
+
+ (scm_check_freelist): No need to flush streams before abort().
+
+ (scm_gc_for_newcell): Try to allocate new memory in three phases:
+ grow heap if preferred, if still no memory available collect
+ garbage, if still no memory available grow heap.
+
+ (heap_segment_table_size): Added to always reflect the actual
+ size of the heap segment table, because scm_n_heap_segs may differ
+ from the heap segment table size.
+
+ (alloc_some_heap): In case of malloc failure, react according to
+ the new policy_on_error parameter (either return to caller or
+ abort immediately). Further, keep heap_segment_table_size up to
+ date.
+
+ (scm_init_storage): Initialize heap_segment_table_size.
+
+2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
+ the hint.
+
+2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,

+ SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
+ SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
+ symbols.
+
+ * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
+ and SCM_NALLOC, but as a deprecated feature.
+
+2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
+
+ * debug.c: Added #include fluids.h.
+
+ * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
+ primitive generics. (Thanks to Nicolas Neuss.)
+
+2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * gc.c (alloc_some_heap): Use scm_memory_error to indicate a

+
+ (scm_gc_for_newcell): Changed the control structure to make the
+ behaviour explicit for the case that gc is not able to free any
+ cells.
+
+2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * __scm.h (SCM_OUTOFRANGE): Removed.
+
+ * error.c (scm_wta): Removed sick dispatch code for range
+ errors. (More sick dispatches still to be removed.)
+
+ * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
+ scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
+ value is non-negative. Use scm_out_of_range to signal range
+ errors.
+
+ * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
+ signal range errors.
+
+ * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
+ error reporting (now uses original input parameter to report wrong
+ type argument errors). Use SCM_OUT_OF_RANGE to report range
+ errors and SCM_WRONG_TYPE_ARG to report type errors.
+
+ * strings.c (scm_substring): Make range checks for negative
+ values explicit (former behaviour relied on an implicit
+ conversion from signed to unsigned). Don't use SCM_ASSERT for
+ range checks.
+
+ * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
+ scm_bit_count_star): Use scm_out_of_range to signal range
+ errors.
+
+ * unif.c (scm_transpose_array, scm_bit_position), vectors.c
+ (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,

+
+2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
+ SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
+ Perform all range checks based on the input value. The former way
+ of using the value that is assigned to the target variable fails
+ if the assignment to the target variable itself can change the
+ value because of type conversion.
+
+ (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
+
+2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
+ doesn't yield any new cells. In theory this could happen if all
+ cells allocated with NEWCELL are either in use or conservatively
+ marked and all cluster spine cells are conservatively marked.
+ (Thanks to Dirk.)
+
+2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * __scm.h (SCM_NALLOC): Removed.

+ * list.c (scm_cons_star): Updated comment.

+ * random.c: #include <string.h>. (Needed by memcpy.)

+ programs.)
+ (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't

+2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
+
+ * guile-doc-snarf.in: don't pipe the CPP output right into sed --
+ write it to the temp file first and check the CPP return code.
+ (I introduced this bug earlier, and this probably caused people
+ with non-GNU C preprocessors to get empty *.x files and not to
