barriers more correctly.
* weaks.c (scm_scan_weak_vectors): move the calculation of the
`weak_keys' and `weak_values' flags out of the inner loop.
2000-12-29 Michael Livshin <mlivshin@bigfoot.com>
* guardians.c: (greedily_guarded_prop): deleted.
(greedily_guarded_whash): new variable. a doubly-weak hash table
used to keep the "greedily guarded" object property. the previous
implementation (via primitive object properties) was incorrect due
to its only-the-key-is-weak semantics.
(scm_guard, get_one_zombie, scm_init_guardians): use/init
`greedily_guarded_whash'.
2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>

* continuations.c (scm_make_continuation): Make variable cont
volatile to let the compiler know that it won't be clobbered by
longjmp. (It wouldn't be anyway, but for some reason the compiler
is not able to see that.)
2000-12-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
This patch re-introduces the unused member "properties" of
struct scm_subr_entry as requested by Mikael Djurfeldt.

'=='. also, return after calling `scm_gc_mark'.
2000-12-24 Michael Livshin <mlivshin@bigfoot.com>
* gc.c: (scm_gc_mark_dependencies): new function. like
`scm_gc_mark', but doesn't mark the argument itself. defined
using an arrangement similar to that in eval.c: `scm_gc_mark' and
`scm_gc_mark_dependencies' are derived from the same "template"
by ugly preprocessor magic.

`scm_init_guardians'.

`listed_p'.
(GUARDIAN_P): predicate that says whether its argument is a
guardian.
(GUARDIAN_GREEDY_P, GUARDIAN_LISTED_P): new predicates.
(greedy_guardians, sharing_guardians): new variables. hold the
greedy and sharing live guardian lists, respectively.
(first_live_guardian, current_link_field): removed.
(greedily_guarded_prop): new variable. holds the "is greedily
guarded" object property.
(self_centered_zombies): new variable. stores guarded objects
that are parts of cycles.
(add_to_live_list): new function, introduced to decouple marking a
guardian and adding it to the live list.
(guardian_mark): call `add_to_live_list'.
(guardian_print): print whether the guardian is greedy or not.
also change "live" and "zombie" to "reachable" and "unreachable"
respectively, to be less confusing.
(scm_guard): if the guardian is greedy, test whether the object is
already greedily marked. throw an error if so.
(scm_get_one_zombie): if the guardian is greedy, remove the
"greedily guarded" property from the object.
(scm_make_guardian): add a new optional boolean argument which
says whether the guardian is greedy or sharing.
(guardian_gc_init): init the new live lists.
(mark_dependencies): new function.
(mark_and_zombify): new function.
(guardian_zombify): reworked to support the new guardian
semantics. move some logic to `mark_dependencies' and
`mark_and_zombify'.
(whine_about_self_centered_zombies): new function. installed in
the `after-gc-hook' to complain about guarded objects which are
parts of cycles.
(scm_init_guardians): init the new stuff. renamed from
`scm_init_guardian'.

"documentation".
(SCM_SUBR_DOC): Deprecated.

favor of scm_str2symbol. Similarly, prefer scm_sysintern over
scm_sysintern0.
(scm_make_subr_opt, scm_mark_subr_table): Struct scm_subr_entry
does not have a member "documentation" any more.
2000-12-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

current environment will take effect when re-entering the dynamic
scope.
2000-12-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

Mikael Djurfeldt.
2000-12-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
The variable scm_symbols is made static within symbols.c and
renamed to symbols. The initialization of the symbols hash table
is done in function scm_symbols_prehistory.
* gc.c (scm_init_storage): Don't initialize scm_symbols. Don't
define most-positive-fixnum, most-negative-fixnum and
bignum-radix.

for creating symbol objects and storing them in the global
scm_symbols hash table.
(scm_str2symbol): Rewritten in terms of scm_mem2symbol.
(scm_sym2vcell): For system bindings, there is now only one
obarray - scm_symhash. If scm_sym2vcell is called to look up a
symbol that can't be found and shall not be created, #f is
returned. Most callers of scm_sym2vcell have expected this
behaviour anyway.
(scm_intern_obarray_soft): Removed reference to scm_weak_symhash
from comment.
(scm_intern_obarray_soft, scm_sysintern0_no_module_lookup): These
functions are not responsible for symbol creation any more, only

setting its cdr).

* hash.[ch] (scm_string_hash), symbols.[ch] (scm_string_hash):
Moved function scm_string_hash to hash.c.

scm_get_keyword, scm_slot_ref_using_class,
scm_slot_set_using_class_x): Update the code to match guile's

of scm_tc7_contin. call scm_init_continuations before
scm_init_root.

wrapper for the dup2 system call (unlike dup->fdes or
primitive-move->fdes).
* ioext.h: declare scm_dup2.
* filesys.c (scm_close_fdes): new proc. implements "close-fdes"
which is a simple wrapper for close system call (unlike scm_close).

2000-11-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
* backtrace.c (display_expression, display_error_body), fports.c
(prinfport), print.c (scm_iprin1): Test for symbols and strings
explicitly instead of using SCM_ROSTRINGP.
* backtrace.c (scm_display_error_message): Don't pass a symbol to
scm_simple_format. Prefer high-level output functions.

table names are symbols.

2000-10-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* unif.c (scm_make_uve, scm_dimensions_to_uniform_array): Don't
allow vectors longer than SCM_LENGTH_MAX. This removes the
SCM_HUGE_LENGTH trick, i. e. storing a vector length greater than
SCM_LENGTH_MAX at the beginning of the vector's memory. Since not
all of guile's code was implemented to be aware of this trick, it
is unlikely that it was used anyway. We can implement such a
feature more cleanly by using double cells for uniform vector
types.
(scm_shap2ra): Replace SCM_IMP and SCM_NIMP tests by more
straightforward predicates.
(scm_dimensions_to_uniform_array): Require that for dimensions
given as lower-bound/upper-bound pairs the upper-bound is never

* dynl.c (scm_coerce_rostring): Removed.
(scm_dynamic_func): Changed the comment to reflect that the
function name has to be a string. Further, hide implementation
details from the scheme comment.
* error (scm_error_scm): Don't accept a symbol as message
parameter. Fix substring handling.
* posix.c (environ_list_to_c): Use memcpy to copy environment
strings. Handle substrings which don't have a trailing \0.
* symbols.h (SCM_LENGTH, SCM_ROLENGTH, SCM_SUBSTRP,
SCM_SUBSTR_STR, SCM_SUBSTR_OFFSET, SCM_COERCE_SUBSTR):
Deprecated.

2000-10-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
* random.c: Include unif.h.
* strings.h (SCM_STRING_COERCE_0TERMINATION_X): Added. This is
intended to replace the macro SCM_COERCE_SUBSTR. Such a macro
will be necessary, even after copy-on-write strings will be added
to guile, but the current naming is inappropriate.
* strorder.c (scm_string_equal_p, scm_string_ci_equal_p,
scm_string_less_p, scm_string_ci_less_p): Don't accept symbols as
input parameters. Further, the functions that test for equality
are rewritten to compare from back to front, the others are also a
little bit more polished.
2000-10-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
This change merges the GOOPS code into Guile. However, GOOPS
is still not initialized until someone asks for the module.
We need to optimize GOOPS initialization time before initializing
it together with the rest of libguile. We also need to add the
C API + primitive methods. Then we can start using it to
modularize Guile, implement a real exception system etc.
* goops.c, objects.c, objects.h, eval.c (scm_make_extended_class,
scm_make_port_classes, scm_change_object_class,
scm_memoize_method): Changed to ordinary functions (was plugin
slots).
* goops.c (wrap_init, scm_wrap_object): Unconditionally use
SCM_STRUCT_GC_CHAIN.

scm_shared_array_increments): Removed.
(scm_init_goops): No need to support two arg mutex init.
Removed #include "versiondat.h", #include "goops.h".
* goops.h: Removed various superfluous conditions.
Renamed class --> cls, new --> newinst in order to accomodate
C++.
* init.c (scm_init_guile_1): Call the goops module registration
function.
Added #include "libguile/goops.h".
* Makefile.am (libguile_la_SOURCES): Added goops.c
(DOT_X_FILES): Added goops.x
(DOT_DOC_FILES): Added goops.doc
(modinclude_HEADERS): Added goops.h

symbols.h (SCM_COERCE_SUBSTR): Use SCM_STRING_LENGTH instead of
SCM_ROLENGTH if the object is known to be a string or substring.
* eval.c (scm_lookupcar): Use SCM_ITAG7 instead of doing bit
operations directly.
* filesys.c (scm_dirname, scm_basename): Don't create shared
substrings as these are going to disappear from guile.
* gc.c (scm_gc_sweep): Use SCM_UVECTOR_LENGTH instead of
SCM_HUGE_LENGTH. (The SCM_HUGE_LENGTH mechanism does not work
correctly anyway.)
* gc.h (SCM_FREEP, SCM_NFREEP): Deprecated.
* read.c (scm_flush_ws): Don't compare SCM values directly.
* root.c (scm_make_root), root.h (scm_root_state): Removed

scm_string_append), strop.c (scm_string_copy), struct.c

produce guile-procedures.txt.
* guile-snarf.awk.in: Modify the way we snarf docstrings such that
the output is Texinfo-compliant and suitable for post-processing
with makeinfo. (Trim leading "./" from C file name if
present; reformat procedure prototype line in @deffn format;
improve representation of args to show optional and rest args;
explicitly quote quotation marks where they are used inside an AWK
regexp.)
* net_db.c (scm_inet_ntoa): Docstring fix: missing newline

2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
This patch unifies the formerly distinct ssymbol and msymbol types
to a common symbol type scm_tc7_symbol. The representation of the
new symbol type uses a double cell with the following layout:
<type/length, chars, raw_hash, prop-pair>, where the car of
prop-pair holds the symbol's function property and the cdr of
prop-pair holds the symbol's other properties. In the long run,
these properties will be removed. Then, the generic property
functions will be uses.
* eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
(scm_iprin1), tag.c (scm_tag): Use scm_tc7_symbol instead of
scm_tc7_ssymbol, scm_tc7_msymbol or scm_tcs_symbols.
* gc.c (scm_gc_mark): Mark the symbols property pair.
(scm_gc_sweep): There are no symbol slots any more.

* properties.h: Fix typo.
* strings.[ch] (scm_makstr, scm_makfromstr): The slot parameter
is not used any more.
* symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
(scm_intern_obarray_soft): Made softness parameter unsigned.
(scm_string_hash): New function with the same functionality as
scm_strhash had before, except that the hash value is not adjusted
to a hash table size. Instead, the 'raw' hash value is returned.
* symbols.c (duplicate_string): New static convenience function.
(scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
Renamed local variable from scm_hash to hash.

any more. When generating symbol cells, use the new layout and
store the raw hash value in the symbol's cell.

(scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
determine the hash values.

Deprecated.
2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

compiled closures. Include "libguile/smob.h".
(f_eval_closure): Removed.
(scm_eval_closure_tag): New variable.
(scm_eval_closure_lookup): Renamed from eval_closure.
This function now takes a smob instead of a compiled closure.

obarray_remove): Make sure the hash value is a valid obarray
index.
(obarray_enter, obarray_remove): Documentation improved.
(obarray_replace): Added.
(leaf_environment_define, leaf_environment_undefine): Cleaned up
and optimized.
2000-09-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>

properties.c.
* throw.c (scm_ithrow): Perform catch-all handling here when no
suitable handler has been found. That way, we don't have to rely
on the user establishing a catch-all, which might be difficult for
him if he is using scm_init_guile instead of scm_boot_guile.
2000-09-03 Neil Jerram <neil@ossau.uklinux.net>
* vectors.c (scm_vector): Docstring: add @deffnx line for

the following changes let Guile get rid of the `allocated' cell
state.

type.
* tags.h (scm_tc16_allocated): removed.
* gc.h: removed now-obsolete comments about the `allocated' cell
state.

* objects.c (scm_init_objects), print.c (scm_init_print), struct.c
(scm_init_struct): First arg to scm_make_vtable_vtable should be a
string, not a symbol. (`make-vtable-vtable' needs to append this
string to another string and then pass it through
`make-struct-layout'.)
* stacks.c (scm_init_stacks): Pass a string, not a layout object,
to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
* struct.c (scm_make_struct_layout): Removed reference to
"read-only string" in comment; Check that argument is a string.
(scm_make_vtable_vtable): Check that argument is a string.
* environments.c (scm_init_environments): All internal includes in
libguile must use the prefix "libguile/" in path names since inly
the top-level source directory is on the include list. (That, in
turn, is because we want to distinguish between system header
files and hedares files internal to libguile.)
* strings.c (scm_make_shared_substring, scm_read_only_string_p):
Deprecated.
(scm_string_length, scm_string_ref, scm_substring,
scm_string_append): Don't accept symbols as arguments (R5RS).

* procs.c (scm_procedure_p): Check applicable smobs.
2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
also here. (This is supposed to make sure that scmconfig.h is
built before all sources in order to prevent that everything has
to be rebuilt again. Hope it works---I'm just guessing. :)
* fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
extra tests. (GUILE_DEBUG is only supposed to make extra
debugging functions available.)
2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
* gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
constant.
2000-08-19 Michael Livshin <mlivshin@bigfoot.com>

fallen through the cracks in the merge. thanks to Shuji Narazaki!

texinfo markup and remove trailing newlines.
2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
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.

locations anymore.
(SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
cards and bvecs (bit-vectors).

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.
(BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
current_mark_space_offset, mark_space_head, get_bvec,
clear_mark_space): new functions and supporting variables, types
and macros that implement mark space management.
(scm_igc): clear the mark space (all of it) before beginning the

(scm_cellp): ditto.
(scm_gc_sweep): simplified.
(init_heap_seg): changed to take cards into account.
2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
* 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.
* gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
sweep time, total marked cells, total swept cells, and number of
times GC was invoked.
(gc_start_stats): renamed from scm_gc_start, made static, taught
to init the new stats.
(gc_end_stats): renamed from scm_gc_end, made static, taught to
calculate the new stats.

are indeed going to collect. also, added some timekeeping between
the mark and sweep phases.
(scm_gc_sweep): count number of cells we sweep as we go.
* gc.h: removed prototypes for scm_gc_{start,end}.
2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
* alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
error for the alist rather than the sublist where the type
mismatch is discovered.

2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
The following changes are intended to ensure that struct instances
are freed before their vtables. It's optimized for the most
common case, which is freeing of struct instances.
* gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
(scm_structs_to_free): New variable.

(thanks to Richard Kim for the bug report).
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'.

key, not all.
2000-07-24 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

eq, eqv, or equal to the first cell with the argument key. Thanks
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

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.

standard initialization functions.
2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>

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_VALIDATE_CELL): Delegate cell checks to function
scm_assert_cell_valid to allow extensions to the checking
functionality without need to recompile everything.
* gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
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.

* 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,

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_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_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
failed attempt to get additional memory from the system.
(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,
scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
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.
* error.c (scm_wta): Removed sick dispatch code for memory
errors. (More sick dispatches still to be removed.)
* numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
(scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
(scm_vector_set_length_x): Now using scm_memory_error to signal
memory errors.
2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h: Removed some commented code and fixed some comments.
(SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
* async.c: Removed some commented code.
2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
scm_must_realloc, scm_must_free, alloc_some_heap): Use the
appropriate error signalling function.
2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
* root.h (scm_first_type): Removed.
2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.c (MIN_GC_YIELD): Removed.
2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
* gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
allocate instead.
2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
* async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
Moved to gc.c.
(scm_init_async): Moved initialization for scm_gc_async and
scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
from gc.c.
* async.h (scm_gc_async): Not globally visible any more.
* gc.c (scm_gc_stats): Made callable even from within regions
where gc is blocked.
(scm_gc_end): Eliminate the hardcoding of the marking of the
scm_gc_async from the gc core.
(scm_init_storage): Don't initialize the scm_asyncs list here.
This is now done in asyncs.c.
(scm_gc_vcell): Moved here from async.c.
(gc_async): Renamed from scm_gc_async, moved here from async.c
and made static.
(gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
here from async.c.
(mark_gc_async): New hook function for scm_after_gc_c_hook.
(scm_init_gc): Added initialization of scm_gc_vcell and
gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
* init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
initialized.
2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.c (scm_igc): Removed commented code that once was intended
to unprotect struct types with no instances.
* root.h (scm_type_obj_list): Removed.
2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
* async.c (scm_init_async): Switch to standard way of smob
initialization.
2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
* guile-doc-snarf.in: use cut instead of sed, that's much much
faster. also, don't call basename more than needed. and, to gain
a couple of microseconds more, don't call cat needlessly. (thanks
to Brad Knotwell).
2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
* guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
#include "libguile/fluids.h".
* eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
* root.h (scm_top_level_lookup_closure_var,
scm_system_transformer): Removed. (It's no sense in having the
*variable* be a "fluid".)
* root.c (mark_root): Removed marking of
s->top_level_lookup_closure_var and s->system_transformer.
* modules.c (scm_selected_module): the_module is now a fluid.
2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.h, tags.h: Be kind to compilers which must see hash signs in
column 0. (Thanks to Ian Grant.)
* numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
the long_long type. (Thanks to Bernard Urban.)
2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* gc.c, gc.h (scm_default_init_heap_size_1,
scm_default_min_yield_1, scm_default_init_heap_size_2,
scm_default_min_yield_2, scm_default_max_segment_size): New global
variables. Can be customized by the application before booting
Guile. (We might want to be able to control these parameters
dynamically through the "options interface" in the future, but
note that that is additional functionality. Here we're giving
default values which the environment variables can override.)
* list.c (scm_cons_star): Updated comment.
* smob.h: Changed comments for scm_make_smob_type and
scm_make_smob_type_mfpe, warning that the latter might be
deprecated in a future release.
2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
* list.[ch] (scm_cons_star/cons*): Renamed from
scm_list_star/list*.
* list.[ch] (scm_list_star/list*): Provided as a deprecated alias
for scm_cons_star/cons*.
* gc.c (scm_protect_object): Updated comment.
* numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
* tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* init.c, init.h (scm_initialized_p): Renamed from `initialized'
and made global.
* gdbint.c (gdb_print): Print warning instead of calling scm_write
if Guile isn't yet initialized.
* print.c (scm_current_pstate, scm_make_print_state): Simplified
tests, using the assumption that Guile has been initialized.
Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
* print.c (s_scm_current_pstate): Do not segfault when the
print_state_pool is unitialized in `current-pstate', and better
verify its state before altering it in scm_make_print_state().
2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
* scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
#ifdef -- it's missing on at least one platform. (thanks to
Jan Nieuwenhuizen).
2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
* list.c (list*): Added documentation from common-list.scm.
2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.c (scm_unprotect_object): The reference count is guaranteed
to be a positive number.
2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* eval.c: Updated comment above scm_map.
2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.c (scm_protect_object): Avoid looking up the object handle
twice.
(scm_unprotect_object): Abort if scm_unprotect_object is called on
an unprotected object.
2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
* gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
Dirk Herrmann).
2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* socket.c (scm_getsockopt): Changed type for `optlen' from int to
size_t.
(scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
Ditto for `tmp_size'.
(scm_addr_buffer_size): Changed type from int to size_t.
* random.c: #include <string.h>. (Needed by memcpy.)
* guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
indicating stdin, instead of "" and don't reset ARGC. This is a
workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
it is correct, and perhaps even better.
2000-06-14 Gary Houston <ghouston@arglist.com>
* scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
defined, add SA_RESTART to the sigaction flags correctly
(thanks to Dale P. Smith).
2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
* net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
* Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
since read and write buffers are allocated by `malloc'.
* Makefile.am: Removed old test code.
* gh_test_c.c, gh_test_repl.c: Removed.
2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
compiler.
* inet_aton.c (inet_aton): Cast init value for `cp'.
* ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
`scm_tc7_uvect'.
* symbols.c (scm_intern_obarray_soft,
scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
in calls to scm_strhash.
* strports.c (st_resize_port): Substituted SCM_UCHARS for
SCM_CHARS.
(st_write): Cast argument to strncpy to char ptr.
(scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
(scm_strport_to_string): Cast argument to scm_makfromstr to char
ptr.
* ports.c (scm_ungetc): Cast value to unsigned char ptr before
storing in putback_buf.
(scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.

scm_do_read_line to unsigned char ptr.
* gdbint.c (SEND_STRING): Cast argument to char pointer.
* fports.c (fport_flush): Declare `ptr' as unsigned char (was
char).
* Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
shouldn't use Make rules which aren't supported by most Make
programs.)
(OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
want these dependencies recorded, since they would get bogus
relative paths; libguile.h is only used in gh.h and guile.c.)
(EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
(guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
(modinclude_HEADERS): Removed kw.h.
* guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
(The preprocessor might insert spaces before the identifier.)
* snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
* smob.h (scm_smobfuns): Removed deprecated type.
* smob.c, smob.h (scm_newsmob): Removed deprecated function.
(Replaced by `scm_make_smob_type'.)
* keywords.c (scm_tc16_kw): Removed deprecated type.
(Replaced by scm_tc16_keyword.)
* kw.h: Removed deprecated header file.
* evalext.c (serial-map): Removed deprected alias for scm_map.
(Has been replaced by `map-in-order'.)
* ramap.c (serial-array-copy!, serial-array-map!): Removed
depracted aliases. (Replaced by `array-copy-in-order!' and
`array-map-in-order'.)
2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* gc.h (SCM_VALIDATE_CELL): Rewritten.
(SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
(Thanks to Han-Wen Nienhuys.)
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
have the build fail right away...).
* scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
-- at least my libc5-based Linux system doesn't define SIGSYS.
2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
(Thanks to Bernard Urban.)
2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* modules.c (scm_system_module_env_p): Fixed detection of system
modules.
2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
* scmsigs.c (scm_sigaction): Silently ignore setting handlers for
`program error signals' because they can't currently be handled by
Scheme code.
2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* procs.h (SCM_SET_SUBRF): Added.
* procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
report.
2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
value.
* sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
scm_merge_list_step): Don't take the address of SCM_CAR. Use
SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* boolean.h (SCM_TRUE_P): Removed, as people might use it as a
replacement for !SCM_FALSEP.
* backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
(scm_unhash_name), gh_data.c (gh_module_lookup), load.c
(scm_primitive_load), print.c (scm_simple_format), procs.c
(scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
(scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
(narrow_stack, scm_make_stack, scm_stack_id), symbols.c
(scm_string_to_obarray_symbol), throw.c (scm_catch,
scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* eval.c (scm_badformalsp): New static function.
(SCM_CEVAL): Check arguments for procedure-with-setter closures.
(Thanks to Keisuke Nishida.)
The major reason for Guile's slow loading speed has been the fact
that a chain of Scheme level procedures has been evaluated for
every top-level symbol lookup during the first pass through the
code.
The following is a kludge which I suggested four years ago, and
which I've repeatedly suggested since. Personally, I've never
been bothered by Guile's slow loading speed, so I thought I would
let someone else do it...
But since the new environments will be included first in
Guile-1.5, I thought it would make people happy to get the kludge
into 1.4.
* modules.c: Added #include "libguile/vectors.h";
Added #include "libguile/hashtab.h";
Added #include "libguile/struct.h";
Added #include "libguile/variable.h";
Capture Scheme level `module-make-local-var!' to be used in the
standard eval closure.
(scm_standard_eval_closure): New primitive.
* modules.h (scm_standard_eval_closure): Declare.
* eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
* symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
standard eval closures.
* variable.c: Code layout fixes.
2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* Makefile.am: Added LIBS line to libpath which accidentally
disappeared in the change of 2000-06-01.
(Thanks to Dale P. Smith.)
2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* scmsigs.c (scm_segfault): Removed. (Was probably added by
mistake since it is not mentioned in ChangeLog.)
* gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
avoid compiler warnings in gcc. (Does this work for other
compilers?)
2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
abort ().
(SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
the address of these expressions since they use SCM_VALIDATE_CELL.
(Thanks to Bernard Urban.)
* dynl.c: Changed #include <ltdl.h> --> #include
"libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
2000-06-01 Craig Brozefsky <craig@red-bean.com>
* Makefile.am: libguile_la_LDFLAGS gets -version-info args
from GUILE-VERSION definition of LIBGUILE version. Added to
libpath.h definitions for guileversion and libguileversion which
both get their values from GUILE-VERSION definition.
2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
file: Code using numbers should not be required to include
smob.h.
2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
* coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
mit-pthreads.c, mit-pthreads.h: Deleted.
* Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
references to deleted files and fsu/mit thread support in
general.
2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
* hooks.c (symbol_name, scm_create_hook): Restored the original
behaviour of scm_create_hook. Changing it was bad as Carl
R. Witty has pointed out.
* gc.c (scm_init_gc): We can still rely on scm_create_hook to
protect the object.
2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
soon not be done by scm_create_hook any longer.
* hooks.c (make_hook, print_hook, scm_create_hook,
scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
longer have names. As an intermediate solution, the name
predicate is emulated via object properties, but use of this
feature is deprecated.
* hooks.h (scm_free_hook): Removed, as it is never defined.
2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
Un-deprecated since otherwise user code can't determine whether a
number fits into an inum any longer. The names should be changed
some time, though.
* numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
* tags.h (SCM_UNPACK_CAR): Deprecated.
2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
(SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
Replace SCM_UNPACK_CAR appropriately. Don't access cells via
SCM_{SET}?C[AD]R unless they are known to be cons cells.
* gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
init_heap_seg): Remove unused struct member variable 'valid'.
2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
* fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
appropriately.
2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.c (free_list_length), hash.c (scm_hasher), macros.c
(scm_macro_type), objects.c (scm_class_of), options.c
(scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
(SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
* eval.c (scm_force): Add documentation.
* eval.c (scm_force, scm_cons_source): Don't access cells via
SCM_{SET}?C[AD]R unless they are known to be cons cells.
2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
* strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
(SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
* gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
nosve #endif conditionally compiled code.
2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
* gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
* guile-doc-snarf.in: put the preprocessed file through sed to
trim all lines to 1024 chars. I hope it doesn't break anybody's
sed. we'll see. (note: this is lossy trimming, i.e. the spill
isn't wrapped around but actually chopped off. this seemed to me
safe because the current snarfer doesn't understand multi-line
cookies anyway. in the long term, it would be nice not to depend
on AWK for anything.)
* gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
the previous change to this macros, after deciding to torture the
snarfer instead.
2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
* gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
the yucky, ugly and nasty conditional compilation back. sorry,
but it was either that or requiring GAWK to build Guile.
(lots of places): removed the code that implemented the old GC
scheme.
* init.c (scm_boot_guile_1): removed the code conditioned on
!GUILE_NEW_GC_SCHEME.
* __scm.h: (GUILE_NEW_GC_SCHEME): removed.
* gc.c (scm_protect_object, scm_unprotect_object): change the
implementation to more efficient (at least in the time complexity
sense). the calls should now also be thread-safe -- I suspect
that people expect them to be. (thanks to Han-Wen Nienhuys)
(lots of places): removed the code that implemented the old GC
scheme.
* hashtab.c (scm_hash_fn_create_handle_x): add missing
SCM_REALLOW_INTS before return. I really wonder about the
possible interactions between hashtables, threads & GC. it
doesn't look healthy at all.
2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
* unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
Dale P. Smith.
2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
debug option to verify all accesses to cells actually access
objects on the heap.
* gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
SCM_DEBUG_CELL_ACCESSES is set to 1.
(SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
that is accessed.
2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
* gc.c (scm_cellp): Fixed and simplified.
* throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
make_jmpbuf, scm_init_throw): Now using double cells to represent
jump buffers when using debug extensions.
(freejb): Removed.
2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
gh_module_lookup): Accept const pointers as parameters.
* gh.h gh_data.c (gh_int2scmb): Deprecated.
2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
the actual arguments in the list, but rather the rest argument as
a list of arguments.
* validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
* async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
(scm_list_star, scm_append, scm_append_x), ports.c
(scm_close_all_ports_except), ramap.c (scm_array_map_x,
scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
(scm_make_stack), strings.c (scm_string_append), struct.c

* dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
scm_dynamic_link, scm_init_dynamic_linking), dynl.h
(scm_dynamic_link): Removed possibility to pass flags to
scm_dynamic_link, as it had no effect anyway.
* filesys.c (scm_fcntl): Made single optional rest argument into
a standard optional argument.
* hooks.c (scm_run_hook): A list of rest arguments is never
SCM_UNBNDP.
* list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
strings.c (scm_string_append): Don't perform half-hearted checks
to see whether the rest argument forms a proper list any more, use
SCM_VALIDATE_REST_ARGUMENTS instead.
* ports.c (scm_close_all_ports_except): Accept empty list of rest
arguments.
* posix.c (scm_convert_exec_args), print.c (scm_simple_format):
Simplify verification of rest argument.
* stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
(ss_handler, handler_message): Make first mandatory rest argument
of scm_make_stack into a standard mandatory argument.

scm_array_in_bounds_p), unif.h (scm_transpose_array,
scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
rest argument into a standard mandatory argument.
2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>

Keisuke Nishida for the suggestion.) Added debug option
SCM_DEBUG_REST_ARGUMENTS.
* eval.c (scm_map, scm_for_each): Make sure all lists have the
same length. Also, removed redundant parameter checks.
2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>

(scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
SCM_INUM): Removed conditionally compiled code for Turbo C.
* gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
That check can be assumed to be redundant except for very rare
conditions that actually indicate broken heap data.
2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_logcount, scm_integer_length): Reordered
dispatch sequence.
2000-05-15 Gary Houston <ghouston@arglist.com>
* stime.c (scm_strftime): don't reset TZ if zone is an empty
string. append a "0" to the zone for TZ.
2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
sequence.
(scm_bit_extract): Fixed handling of bignums.
2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>

scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
(scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
* fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
scm_output_port_p), print.c (scm_get_print_state), validate.h
(SCM_VALIDATE_CHAR): Replace use of deprecated macros
SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
2000-05-14 Gary Houston <ghouston@arglist.com>
* stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
TZ environment variable so that the %Z format returns the zone
from the input vector instead of the system default.
from Keisuke Nishida:
* fports.c (scm_setvbuf): minor docstring fix.
* ports.h (scm_generic_fgets): obsolete prototype deleted.
2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
* __scm.h: Added new section for debugging options.
(SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
help developers to get rid of references to deprecated code.
* numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
as part of the interface and are marked as deprecated in the
header file.
* numbers.c (scm_make_real, scm_make_complex): Inlined the
corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
respectively.
* numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
of two scm_bits_t values instead of two SCM values, because it is
legal for cell entries to hold values that are not scheme objects.
(SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
Use SCM_SETC[AD]R to modify contents of pairs.
2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (IS_INF, isfinite): Added FIXME comment.
(scm_abs, scm_magnitude): Make these two independent of each
other. scm_abs now reports an error if given a complex argument.
(scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
SCM_REALPART if the object is known to be real.
(scm_init_numbers): No need to use SCM_NEWREAL macro for speed
here.
* numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eq.c (scm_eqv_p): Separate handling of real and complex

scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
the object is known to be real. Use SCM_COMPLEXP instead of
deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
SCM_INEXP.
2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c: No need to include unif.h.
(IS_INF): Returned to old test for now: x == x + 1 will not work
for large numbers due to rounding errors.
Thanks to Kalle Olavi Niemitalo.
2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_divbigdig): Removed outdated comment.
(scm_number_to_string, scm_string_to_number, scm_number_p,

(add1, scm_init_numbers): Removed add1.
2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (IS_INF): The new test is x == x + 1. The old test
x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
and Ivan Toshkov.
(scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
dispatch sequence.
2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
* scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
SIGILL and SIGBUS signals. These signals are not continuable and
must be handled for real right away.
2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
scm_real_part, scm_imag_part, scm_magnitude,
scm_inexact_to_exact): Reordered dispatch sequence.
2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
* feature.c: No need to include "libguile/smob.h"
(scm_loc_features, features, scm_add_feature, scm_init_feature):
Removed variable 'scm_loc_features' as a pointer to the SCM value
holding the features list. Using variable 'features' instead,
which holds the interned pair. Thus, SCM_SETCDR can be used
instead of pointer trickery.
2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
* alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
cell is not known to be a valid pair.
2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
ASRTSYNTAX. Using SCM_ASSYNT instead.
(scm_m_body): Don't create a redundant cons cell.
(scm_m_do): Removed redundant test 'bodycheck'.
(bodycheck): Removed.
* stacks.c (stack_depth, read_frame, read_frames): Removed
redundant calculation of size, minimized some variable scopes.
2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
long as a cell is not known to be a valid pair.
(scm_pair_p): Eliminated redundant SCM_IMP test.
2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
scm_deval_args): Eliminated redundant SCM_IMP tests.
* hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
(scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
scm_make_doubly_weak_hash_table): Fixed critical sections.
Thanks to Keisuke Nishida.
2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
Fixed some goto-related initialization bugs (introduced by me).
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.
(scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
better error message when accessing unlinked dynamic objects.
Eliminated call to get_dynl_obj.
2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
* scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
be an array of function pointers instead of being a pointer to an
array returning function. Thanks to Kalle Olavi Niemitalo!
2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_divbigbig, scm_divbigint), numbers.h
(scm_divbigbig, scm_divbigint): Don't return zero any more to
indicate that a division has a remainder, return SCM_UNDEFINED
instead. It is improbable that anyone actually used these
functions outside of numbers.c. For this reason and due to the
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.
2000-05-02 Gary Houston <ghouston@arglist.com>
* Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_logtest, scm_division): Reordered dispatch
sequence, thereby fixing some comparisons of SCM values with
integer constants.
* numbers.h (scm_makdbl): Mark as deprecated at the point of
declaration.
* eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
scm_sys_atan2, scm_make_rectangular, scm_make_polar,
scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
(ramap_rp, scm_array_map_x), random.c (scm_random,
scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
call to scm_makdbl with a call to scm_make_real or
scm_make_complex, depending on whether the imaginary part is known
to be zero.
2000-05-01 Gary Houston <ghouston@arglist.com>
* scmsigs.c: fix the definition of orig_handlers for the case
that HAVE_SIGACTION is not defined (thanks to
Kalle Olavi Niemitalo).
* Makefile.am: remove include_HEADERS (was libguile.h)
libguile.h: moved to top level directory.
2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (SCM_SWAP): Moved to the top of the file to allow for
a wider use.
* numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
scm_logxor): Reordered dispatch sequence, thereby fixing some
comparisons of SCM values with integer constants.
* number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
tests.
2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_quotient, scm_remainder): Removed code that was
conditionally compiled based on BADIVSGNS. BADIVSGNS does not
occur anywhere else throughout guile.
* numbers.c (scm_quotient): Fixed parameter number in error
message.
* numbers.c (scm_remainder): Reordered dispatch sequence.
2000-04-25 Gary Houston <ghouston@arglist.com>
* posix.c (scm_execlp): docstring fix (thanks to Martin
Grabmueller).
2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.c (undef_object): Made into a local static variable
(suggested by Jost Boekemeier).
2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
* pairs.c (cxrs, scm_init_pairs): Simplify initialization of
c[ad]+r functions.
* procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
scm_dsubr, scm_init_iprocs): Removed.
* procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
directly instead of casting a cell to a C struct.
2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
Better modularization of GC extensions through new C level GC
hooks:
* weaks.c (scm_weaks_prehistory): New function: Add
scm_weak_vector_gc_init to scm_before_mark_c_hook; Add
scm_mark_weak_vector_spines to scm_before_sweep_c_hook.
(scm_scan_weak_vectors): New function; added to
scm_after_sweep_c_hook.
* weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
declarations.
* guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
now static.
* guardians.c (scm_guardian_gc_init): Turned into a hook function
and added to scm_before_mark_c_hook.
(scm_guardian_zombify): Turned into a hook function and added to
scm_before_sweep_c_hook.

Added #include "libguile/gc.h".
* gc.h: Added #include "libguile/hooks.h".
* gc.c: Removed #include "libguile/guardians.h".
(scm_before_gc_c_hook, scm_before_mark_c_hook,
scm_before_sweep_c_hook, scm_after_sweep_c_hook,
scm_after_gc_c_hook): New C level hooks.
(scm_after_gc_hook): New Scheme level hook.
(scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
(scm_igc): Moved initialization of scm_weak_vectors and the call
to scm_guardian_gc_init to respective module.
(scm_mark_weak_vector_spines): Moved to weaks.c;
Call to scm_guardian_zombify moved to guardians.c;
Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
scm_after_gc_c_hook at appropriate places.
(scm_init_gc): Initialize scm_after_gc_hook.
* hooks.c, hooks.h (scm_make_hook_with_name): Removed deprecated
function.
* init.c (scm_boot_guile_1): Added `scm_init_hooks'.
* Makefile.am: Added hooks.c, hooks.h, hooks.x.
* feature.c, feature.h: Broke out hook code into separate files.
* hooks.c, hooks.h: New files.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)
* Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
(DEFS): Added. automake adds -I options to DEFS, and we don't
want that.
Removed all -I options except for the root source directory and
the root build directory.
* numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
instead of SCM_ASSERT (0, ...). (Some compilers will complain
about control reaching end of function otherwise, and, besides,
the new code is not less clear.)
* gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
calls to malloc debugging functions.
* init.c (scm_boot_guile_1): Added calls to debug-malloc init
functions.

documentation strings.
* numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
scm_quotient): Reordered dispatch sequence to first handle
immediates, second handle bignums and finally handle generic
functions respectively signal wrong type arguments. Hopefully
this will allow for easier separation when goops is integrated.
2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
* gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM
variable into a pointer to a heap cell.
* gc.c (scm_mark_locations, scm_cellp, init_heap_seg,
scm_unhash_name): Remove redundant cast to SCM_CELLPTR.
2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
* print.c (scm_iprin1): Don't assign zero to SCM values, use
SCM_UNDEFINED instead.

Changed SETCDR --> SET_CELL_WORD_1.
* coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
when thread dies.
2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
* boolean.h (SCM_TRUE_P): New macro.
* boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
(SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
* continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
access continuation data.
(SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
(SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
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_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
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,
SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
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
pointer-arithmetic induced by the SCM_PACK/UNPACK change.
* print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
* gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
* eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
* 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.
2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
* tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
* numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
SCM_UNPACK / SCM2PTR correctly.
2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.c (adjust_gc_trigger): Improved documentation.
(alloc_some_heap): Since gc_trigger is used against
freelist->collected, this is the value which should be used to
predict minimum growth.
2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
* eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
Thien-Thi Nguyen for the patch.)
2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
* numbers.c (scm_ash): Fixed typing problems with the second
parameter and added some documentation. (Thanks Thien-Thi Nguyen
for indicating the problem.)
2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.c, gc.h (scm_gc_yield): New variable.
(adjust_gc_trigger): Use scm_gc_yield.
(alloc_some_heap): Use scm_gc_yield instead of
scm_gc_cells_collected.
* coop-threads.c: Addd #include "root.h", #include "strings.h".
* debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
* gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
trigger adjustmeant: Take yield (freed cells) for all freelists
into account.
(SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
to 50000 cell heap with 45% trigger.
(scm_gc_cells_collected): Reintroduced.
(SCM_HEAP_SIZE): New macro.
(scm_gc_sweep): Reintroduced correct computation of
scm_cells_allocated.
(scm_freelist_t): Corrected commentary for field `cluster_size':
Clustersize counts objects, not cells; New member
`clusters_allocated'.
2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
* *.[hc]: add Emacs magic at the end of file, to ensure GNU
indentation style.
2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* threads.h: Added #include "libguile/throw.h". (Thanks to
Thien-Thi Nguyen.)
2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
* tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
names, anyone got any better ones?)
* gc.h: (typedef struct scm_freelist_t) remove from here.
* gc.c: (CELL_UP, CELL_DN) made these macros take additional
parameter (the span).
(CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
(typedef struct scm_freelist_t) moved here from gc.h, it had no
business being externally visible.
(typedef struct scm_heap_seg_data_t) renamed from
scm_heap_seg_data, to be style-compliant.
(scm_mark_locations) if the possible pointer points to a
double-cell, check that it's properly aligned.
(init_heap_seg) align double-cells properly, work with the
assumption that the segment size divides cleanly by cluster size.
(round_to_cluster_size) new function.
(alloc_some_heap, make_initial_segment) use round_to_cluster_size
to satisfy the new init_heap_seg invariant.

2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* gc.c, gc.h: Cleanup of the change of 2000-03-15.
Cluster sizes are now independent of GC trigger values.
GUILE_GC_TRIGGER_n can now specify a relative trigger value:
A negative integer gives fraction of total heap size in percent.
(SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
* init.c (scm_boot_guile_1): Introduced new variable
GUILE_MAX_SEGMENT_SIZE; New environment variable names:
GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
freeing of segment work with the new GC scheme. (Thanks to
Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
the default, but I'll let this change stay in CVS Guile since this
code is not expected to contain serious bugs.
2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
defined.
(scm_free_list_length): New procedure (GUILE_DEBUG).
Fixed a small but serious bug introduced by the previous change.
* gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
loop and declare as register.
* gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
after GC.
Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
* fluids.c: Docstring patch from Keisuke Nishida. Some
reindentation, too, and a couple formals renamed. Should
fluid-set! return UNSPECIFIED instead of a value?
Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
* Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
generate the latter from the concrete listing of the former. Then
make guile-procedures.txt depend on DOT_DOC_FILES instead of
*.doc, so that rebuilding it works.
Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
* libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
* guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
with nothing and \n, respectively. Thanks Keisuke Nishida for
noticing this problem.
2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
new way of allocating heap. It makes Guile fast, but still
contains bugs.
* gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
allocating heap. The basic idea is to trigger GC every Nth
allocated cell and grow heap when free list runs out. The scheme
has been extended so that GC isn't triggered until all remaining
cells are used. The implementation is also prepared for
development in the direction of POSIX threads.
* gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
SCM_EXPHEAP should return half of the heap size.
2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
The following change to init.c is only enabled if Guile was
configured with --enable-guile-debug.
* init.c (scm_i_getenv_int): New function.
(scm_boot_guile_1): Use the environment variables
GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
they exist. (This may be replaced by a Scheme level mechanism in
the future.)
* objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
scm_assoc. (Thanks to Keisuke Nishida.)
2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* init.c (scm_boot_guile_1): Use same initial segment size for
1-word and 2-word segments. Having the smaller size causes Guile
to GC too often. Obviously something needs to be done to allow
for a smaller 2-word segment without this to happen. (The amount
of heap for each type should be automatically adapted to the
application somehow.)
[Almost all of these changes should be documented in the NEWS
file.]
* gc.h (scm_freelist_t): New type.
* pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
* gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
all of Guile basics fits into one segment and there suitable room
for work.
(SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
instead of 2.
(scm_freelist, scm_freelist2): Now of type scm_freelist_t.
Freelists now contains information about object span, cells
collected and amount of cells in heap segments belonging to the
list.
(scm_heap_size, scm_gc_cells_collected): Removed.
* init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
* Makefile.am (libguile_la_LDFLAGS): Bumped library version
number.
* __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
rewrite of handling of real and complex numbers.
(SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
removed along with the support for floats. (Float vectors are
still supported.)
* tags.h (scm_tcs_bignums): Removed.
(scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
Use SCM_BIGSIGN(x) to test for sign!
(scm_tc16_big): The new bignum type.
(SCM_REAL_PART, SCM_IMAG_PART): Removed.
* numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
(scm_makdbl): Deprecated.
(SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
(SCM_SINGP): Deprecated.
(SCM_FLO): Removed.
(SCM_INEXP, SCM_CPLXP): Deprecated.
(SCM_INEXACTP, SCM_COMPLEXP): New macros.
(SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
(SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
for doubles and complex numbers.
(SCM_REAL_VALUE): New selector for doubles.
(scm_double_t, scm_complex_t): New types.
(scm_dbl): Removed.
* numbers.c (scm_floprint, scm_floequal): Removed.
(scm_print_real, scm_print_complex, scm_real_equalp,
scm_complex_equalp): New functions.
* unif.c (scm_makflo): Removed.
* smob.h (SCM_SMOB_PREDICATE): New macro.
(SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
SCM_RETURN_NEWSMOB3): New macros.
1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
The following changes implement primitive support for double cells
(i.e. four-word cells) and change the representation of some
things to multi-cells instead of cons+malloc. (Applied and
modified by mdj.)
* pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
(SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
multi-cell access macros (used by the ones below).
(SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
macros.
* gc.c (scm_freelist2): multi-cell freelists.
(inner_map_free_list): map_free_list, parameterized on ncells.
"nn cells in segment mm" was misleading for ncells > 1; changed to
"objects". still print cells too, though.
(scm_map_free_list): rewritten using inner_map_free_list.
(scm_check_freelist): get freelist as parameter, since now we have
more than one.
(scm_debug_newcell2): multi-cell variants of
scm_debug_newcell.
(scm_gc_for_newcell): take ncells and freelist pointer as
parameters.
(scm_gc_mark): add case for tc7_pws (procedures with setters are
now double cells).
(scm_gc_sweep): don't free the float data, since it's not malloced
anymore.
(init_heap_seg): didn't understand what n_new_objects stood for,
so changed to n_new_cells.
(make_initial_segment): new function, makes an initial segment
according to given ncells.
(scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
* numbers.c (scm_makdbl): no malloc'ing needed, so the
{DEFER,ALLOW}_INTS thing removed.
* numbers.h (struct scm_dbl): changed to represent a double cell,
with the number in the second half.
* dynwind.c: changed the wind-guards representation to double
cell.
* procs.c, procs.h: changed the procedure-with-setter representation
to double cell.
* async.c, async.h: made async representation a double cell.
* dynl.c: made dynamic_obj representation a double cell.
2000-03-13 Gary Houston <ghouston@arglist.com>
* ports.c (flush_void_port): renamed to flush_port_default.
(end_input_void_port): renamed to end_input_default.
* init.c (scm_standard_stream_to_port): create a void port instead
of opening /dev/null if the standard file descriptors are bad.
advantages: no portability problems, doesn't waste a file descriptor,
simplifies the code (thanks to Marius for the idea).
* vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
* void ports: make reading from a void port give EOF instead of
segv:
* ports.c (s_scm_sys_make_void_port): modified docstring.
(fill_input_void_port): new proc.
(scm_init_ports): set up fill_input_void_port.
* ports.c (scm_port_non_buffer): new proc.
(scm_void_port): call scm_port_non_buffer.
* fports.c (scm_setvbuf): docstring: remove the fcntl documentation
which was incorrectly appended.
2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
that we can't use autoconf for this. Autoconf itself relies on
the existence of `sed' somewhere on your path.) (Thanks to Dirk
Herrman.)
2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
EXTRA_libguile_la_SOURCES.
* iselect.h: Always declare scm_internal_select.
* iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
end. Also let scm_internal_select be a real function also when
not using threads.
* __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
and kind of an experiment: Will this cause problems?)
Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
* Makefile.am: Added *.doc to DISTCLEANFILES.
2000-03-12 Gary Houston <ghouston@arglist.com>
* fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
the fdes is valid before doing anything else. check that
the file descriptor supports the modes required.
(scm_fport_buffer_add): don't throw an error if fstat doesn't
work: just use the default buffer size.
* throw.c: change an outdated comment about scm_internal_catch
BODY: it doesn't take a jumpbuf arg.
* init.c (scm_standard_stream_to_port): install a handler in case
scm_fdes_to_port throws an error. don't check here whether the
file descriptor is valid, since scm_fdes_to_port will do that.
set the revealed count depending on whether the port got the
standard file descriptor.
(stream_body_data): new type.
(stream_body, stream_handler): new procs.
2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
Renamed from SCMWORD.
* tags.h (SCM_NCELLP): Removed (SCMWORD).
* arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
* async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
SCM_ASSCM, SCM_ASWORD, SCM_CARW).
* numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
* alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
tags.h: Fixed copyright notices.
* struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
* init.c (scm_standard_stream_to_port): Check whether the file
descriptor is valid and substitute "/dev/null" when not.
2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* coop-defs.h (struct timespec): Conditionally defined.
* coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
instead of ETIME.
* readline.c (match_paren): Bugfix: First arg to select is not
number of descriptors but the number of the highest descriptor +
1.
This is a preliminary attempt at a cleanup of the threads support
code. It moves things to better places, makes arguments more
consistent with the POSIX API (which is used in GNOME's glib), and
adds new functionality.
* readline.c (scm_init_readline): Added new arg to scm_init_mutex.
* coop-defs.h (scm_mutex_trylock): New macro: alias for
coop_mutex_trylock.
(scm_cond_init): Changed definition to
coop_new_condition_variable_init.
* coop.c: #include <errno.h>
(coop_timeout_qinsert): Moved here from iselect.c
(coop_new_mutex_init, coop_new_condition_variable_init): New
functions. The strange names are temporary. Use scm_mutex_init
and scm_cond_init instead.
(coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
is ANSI C, but should we check for individual error codes in
configure.in?
(coop_condition_variable_timed_wait_mutex): New function.
(coop_key_create, coop_setspecific, coop_getspecific,
coop_key_delete): New functions.
* iselect.c (coop_timout_qinsert): Moved to coop.c
2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
* tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
Layout cleanups.
* objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
* eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
dealing with ilocs.
2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
* numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
logical functions from SCM.
(logand, logior, logxor, logtest, logbit?): Extended scheme
logical functions to use bignums from SCM.
(lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
lognot from using bignums.
Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
* vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
eliminating some warnings.
* unif.c, strports.c, print.c, options.c: Fix some warnings on
mis-use of SCM/long
* gc.c, gc.h: Added scm_return_first_int(), and added comment re:
what the scm_return_first* functions do.
2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
* libguile/*.[ch]: make a distinction between SCM as a generic
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
* numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
various logXXX primitives. Thanks Eric Moore!
Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
* run-test, remaining-docs-needed: Added these scripts. The
second one is only temporary until the docstring additions are
complete. run-test may best live on, but is here mostly for
convenience and awareness for now.
* hash.c: Docs, minor cleanup patch from Dirk Herrman.
Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
* error.h, error.c: Added `scm_wrong_type_arg_msg' to support
displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
* hashtab.c: Improved documentation for lots of functions. Added
handwritten docs for `hash-fold'.
Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
* list.c: Added hand-written docs for `del{q,v,ete}1!'.
Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
* list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
* ports.c: Made `set-port-column!' and `set-port-line!' each
return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
that caused a seg fault. Also fixed `set-port-column!'s
docstring. Thanks Han-Wen Nienhuys for finding the bug!
Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
* arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
strings.c, variable.c: Added lots of documentation, cleaned up
some existing documentation. Occasionally changed formal params
to match docs. Also folded an #ifdef into the inners of a
primitive instead of having two copies of the primitive
(`get-internal-real-time', from stime.c)
Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
* ports.c: Added docs for primitives missing them. Written by
hand.
Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
* guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
just execing guile-func-name-check. Thanks Michael Livshin!
Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
* guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
dead code. Patch from Michael Livshin.
* guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
Michael Livshin.
2000-02-09 Gary Houston <ghouston@arglist.com>
* init.c (scm_init_standard_ports): when stdout is a tty, make the
current-output-port unbuffered by default. this is less confusing
for interactive use. it was line-buffered because of a
performance problem with unbuffered ports, but I think it will be
OK now.
2000-02-08 Gary Houston <ghouston@arglist.com>
* __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
is not defined.
* stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
HAVE_TZNAME are defined, use an empty string instead of giving two
spurious compile-time errors.
Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
* ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
Thanks Richard!
Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
* macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
* pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
(which is GNU GPL'd).
2000-01-31 Gary Houston <ghouston@arglist.com>
* strings.h: don't use SCM_P. don't include <string.h>.
* error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
* strings.c (scm_string_ref): make the 2nd argument compulsory.
previously it defaulted to zero for no good reason that I can see.
use a local variable for SCM_INUM (k). replace
SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
(scm_makfromstr): cosmetic changes.
(scm_string): Accept only chars in the list, not strings, for
conformance to R5RS (particularly for list->string, which is
supposed to be the inverse of string->list.) remove
SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
scm_makstr handles the cell allocation. when reporting wrong-type
arg, don't report the position as 1.
* posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
2000-01-29 Gary Houston <ghouston@arglist.com>
* posix.c (scm_pipe): rewrote the docstring.
* filesys.c (scm_select, retrieve_select_type, get_element,
fill_select_type, set_element): modified so that Scheme
"select" tests port buffers for the ability to provide input
or accept output. Previously only the underlying file descriptors
were checked. Rewrote the docstring.
Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
* vectors.c, symbols.c, strorder.c: Documentation cut and pasted
from Gregg Reynolds. Thanks Gregg!
Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
* strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
adding "x" prefix to the line so that guile-func-name-check
doesn't complain unnecessarily.
Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
* throw.c: Factor out an #ifdef/#else/#endif choice more finely
for maintainability.
* strop.c: Documentation added by Gregg A. Reynolds. Pasted in
from qdocs, RnRs.
Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
* tag.c: Added doc for `tag', but mark as deprecated since Mikael
suggests removing tag.c altogether (and using a new `class-of'
instead).
* strings.c: Added documentation from Gregg A. Reynolds. Edited
a bit by me to use FOO instead of @var{foo} and to have the
summary come before preconditions on input. Also dropped trailing
(rnrs) note.
* gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
function with scm_make_subr_opt w/ last arg of 0 so it is not
visible at the Scheme level. Mikael says that this is the right
thing because the first arg to the proc is the guts of a compiled
closure and shouldn't be exposed to the Scheme level.
Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
* sort.c: typo in comment fixed.
* keywords.c: Added documentation.
* guardians.c: Added documentation (could be better).
* gc.c: Added docs for gc-set-debug-check-freelist.
* eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
* boolean.c: Added docs for `not', `boolean?' (by hand).
Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
* random.c: Added documentation, from SLIB page:
http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
* variable.c, version.c: Added documentation, written by hand
since I could not find anything already written that was
relevant.
2000-01-23 Gary Houston <ghouston@arglist.com>
* filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
not defined (thanks to Richard Y. Kim).
Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
* Makefile.in: Removed, this is auto-generated.
Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
* list.c: Put some variable initialization code at the point of
declaration; Added a comment for list*; Formatting changes.
* load.c: use SCM_NNULLP to make sure the end of a list is not
reached yet.
2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* backtrace.c (scm_display_error_message): Bugfix: Don't use
result of scm_list_p as C boolean.
(scm_display_error_message, scm_set_print_params_x): Use new
validation macros. (Thanks to Dirk Herrmann.)
* net_db.c (scm_resolv_error): Cast result from hstrerror.
* strports.c (st_end_input): Inserted parenthesis to get operator
grouping correct.
* list.h (scm_init_list): Removed SCM_P around prototypes.
* fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
filesys.c, posix.c: Converted docstrings to ANSI C format and
escaped " occurring inside string literals.
Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
* posix.c (scm_mknod): Escape " occuring inside docstring.
2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,

stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
weaks.c: Converted docstrings to ANSI C format.
* filesys.c (scm_chmod), simpos.c (scm_system), version
(scm_version), vports (scm_make_soft_port): Escape " occuring
inside docstring.
Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
* scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
SCM_VALIDATE_LONG_COPY
* numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
couple of formal arguments (and fix their uses) to make arguments
match the documentation.
2000-01-14 <mstachow@alum.mit.edu>
* Makefile.am: Augment path when running guile-doc-snarf so
guile-func-name-check is found.
Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
* scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
def, not SCM_MAKINUM(def); thanks Janis Bzerins!
Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
* net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
the way guile-1.3.4 worked, but #if 0 out the version using
SCM_VALIDATE_INUM_COPY for stricter testing.
Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
* guile-doc-snarf.in: Use new $fullfilename for running
guile-func-name-check, and put "$fullfilename" and "$filename" in
quotes at uses to make sure re-splitting on whitespace does not
occur (so filenames w/ embedded whitespace would work okay, though
I sure hope we never have to deal with that! :-) ). Thanks to
Mikael for pointing out the source_dir != build_dir was broken.
Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
* scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
variants.
* ports.c (scm_port_closed_p): Validate that the arg is a PORT,
then return whether it's an open port (was validating that it was
an open port -- this was a bug I introduced back in December, but
my careful reading of diffs caught it).
* numbers.c: Recombine the two conditional-compilation paths for
all the log* primitives -- they were split based on #ifndef
scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
some bugs and inconsistencies in the two sets of implementations.
(scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
* ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
SCM_VALIDATE_INUM_COPY once where it should've been used.
* fluids.c (scm_internal_with_fluids): Use
SCM_VALIDATE_LIST_COPYLEN.
* filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
this is questionable as it relaxes type safety, but other changes
were useful and all SCM_NUM2LONG's should probably be
revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
* evalext.c: line-break change on 1 line.
* eval.c (nconc2last): Takes a non-empty list as its first
argument, not just a list.
* dynl.c: Use new SCM_COERCE_ROSTRING macro.
Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
* dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
where possible.
* symbols.c (scm_sysintern0): Fixed the function name in a
scm_misc_error invocation.
* print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
use scm_return_first to ward off latent GC bug that Mikael caught.
* async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
used before but should've been.
2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
SCM_FUNC_CAST_ARBITRARY_ARGS.
Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
* guile-func-name-check.in: Added this script to statically check
#define FUNC_NAME, #undef FUNC_NAME in the source.
* sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
redundant comment, semicolon; caught by new guile-func-name-check
script.
* debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
Caught by new guile-func-name-check-script.
* Makefile.am: Added guile-func-name-check to bin_SCRIPTS
* ramap.c: Fix #if 0'd out code to be syntactically acceptable to
guile-func-name-check.
* guile-doc-snarf.in: Run guile-func-name-check on the file before
doing the snarf.
Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
* fports.c, ports.c, ports.h, strports.c, vports.c: Make write
port function take const void*, not void*.
Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
* scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
consistency with the other macros dealing with immediate
characters. (Similar to INT -> INUM change a week or so ago).
Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
* dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.
* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
Finally applied the libltdl patch from Thomas Tanner, with slight
modifications.
* DYNAMIC-LINKING: Removed because it is obsolete.
* dynl.c: Use ANSI prototypes.
(sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
* scmconfig.h.in: Do not change, as it is automatically generated.
1999-07-25 Thomas Tanner <tanner@ffii.org>
* dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
(obsolete)
* Makefile.am: likewise, add INCLTDL (libltdl headers) to
INCLUDES, set dlpreopened files in LDFLAGS, link libguile
against libltdl
* dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
* guile.c: register preloaded modules
* scmconfig.h.in: remove obsolete symbols
2000-01-09 Gary Houston <ghouston@arglist.com>
* These changes should make it unnecessary to call tzset from
Scheme after modifying the TZ environment variable, even if the
system date facilities cache the value.
* stime.c (setzone, scm_localtime): added comments.
(tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
(setzone): don't call tzset.
(restorezone): call tzset only if HAVE_TZSET is defined.
(scm_tzset): don't define if HAVE_TZSET not defined. Change the
doc string to indicate that this procedure isn't likely to do
anything useful.
(scm_localtime, scm_strftime, scm_mktime): call tzset if
LOCALTIME_CACHE is defined.
2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* posix.c (scm_sync): Return SCM_UNSPECIFIED.
2000-01-09 Gary Houston <ghouston@arglist.com>
* eval.c: define scm_unbound_variable_key ('unbound-variable).
scm_lookupcar1: throw an error with key 'unbound-variable instead
of 'misc-error when an unbound variable is encountered.
* filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
scm_symlink, scm_readlink, scm_lstat),
posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
scm_sync),
simpos.c (scm_system),
stime.c (scm_times, scm_strptime):
move the HAVE_XXX feature tests out of the procedure bodies.
don't use SCM_SYSMISSING.
scm_validate.h (SCM_SYSMISSING): removed.
error.h, error.c (scm_sysmissing): comment that this is deprecated.
see ChangeLog entry for 1999-12-28.
Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
* scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
* backtrace.c: Fix spelling typo in a comment.
* snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
text. Reformatted some of the expansions.
Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
* scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
report the position of the argument.
* error.h, error.c (scm_out_of_range_pos): Added this function to
take extra "pos" argument, the position number of the errant
argument.
* debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
* snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
prefers that and I'm reasonably indifferent.
Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
* snarf.h: Factor out differences between C++ and non-C++ into
SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
Mikael's macros, below, but changed names and SCM_SNARFING no
longer expands to include %%% -- that must appear in the argument
so that the token appears at the call-site as a reminder).
2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
* snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
snarf macro definitions.
2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* chars.c (scm_integer_to_char): Use Greg's nice
SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
adherence to R5RS.
Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
* *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
* Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
instead of GUILE_PROC.
Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
* alist.c: Do not report mismatch errors on some uses of `tmp' (do
this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
macro call.
Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
* scm_validate.h: Remove some redundant NIMP tests.
* alist.c: minimize scope of the tmp variables, and initialize
them when declared. The strange SCM_NIMP tests are replaced by
SCM_CONSP tests that more closely reflect the intended semantics.
However, we don't get a performance penalty here, because the
SCM_CONSP test was performed by the ALISTCELL test anyway. * The
extremely ugly use of ASRTGO macros was removed: The calls to
ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
label parameter that only exists when SCM_RECKLESS is not defined.
This works, because ASRTGO itself is defined in a way that it only
makes use of the label parameter if SCM_RECKLESS is not defined
(shudder!). Does guile make at all use of the possibility to
define SCM_RECKLESS? * Codesize is likely to be reduced, since
instead of two calls to SCM_ASSERT performed by the ALISTCELL test
we now only get one test.
* list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
some variables in `list?'. Fix `reverse' and `reverse!'
primitives to handle improper lists better.
Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
* *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
macros and SCM_DEFINE macros to match GNU coding standards.
Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
* *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
* *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
better consistency with the names of other SCM_VALIDATE_ macros
and better conformance to guile naming policy.
Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
* ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
SCM_VALIDATE instead of 1 to avoid a check on the argument (since
it's not the actual name of the formal).
* guile-snarf.awk.in: Do argument/number mismatch checking and
print warnings in an Emacs compile-mode parseable format.
* struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
SCM_OUTOFRANGE as 3rd argument.
* random.c: Fix argument/number mismatch (that I introduced :-( ).
* __scm.h: Do not #define SCM_ARG* when snarfing;
lets us distinguish between 1 and SCM_ARG1 when snarfing as only
the former (using the number) requires the argument to match the
formal in the current argument snarfing check.
* snarf.h: Give new definition of SCM_ASSERT when in
snarfing mode to output a lexically-identifiable sequence that the
guile-snarf.awk script uses to verify argument/position matching.
* ramap.c: Remove extraneous #undef FUNC_NAME.
Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
* guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
current version of the same functionality; it writes the .x output
to stdout instead of directly into the file.
Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
* unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
redundant with the safer macros. Patch from Dirk Hermann applied
by hand. Thanks Dirk!
* scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
uses in random.c.
* ramap.c: whitespace change.
Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
* options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
removals from Dirk Hermann.
* alist.c: Rename formals to match the parameter names in the
documentation, updates to documentation. Thanks Dirk Hermann!
2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* eval.c (SCM_CEVAL): Reverse order of
scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
(Thanks to Brad Knotwell.)
Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
* gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
allocated cell.
* pairs.h: Added a comment about the need for the SCM_SETCAR in
SCM_NEWCELL macro.
Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
* dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
SCM_NIMP tests that were redundant are now eliminated. Patches
from Dirk Hermann applied by hand.
