MV		 132004-01-06 Marius Vollmer <marius.vollmer@uni-dortmund.de>
14
15 * ports.c (swap_ports, scm_with_current_foo_port): Do not allocate
16 swap_data on stack, use a 'malloc obj'.
17
18 * fluids.h, fluids.c (scm_make_initial_fluids, scm_copy_fluids,
19 scm_swap_fluids, scm_swap_fluids_reverse): Renamed to
20 scm_i_... since they are internal. Changed all uses.
21
22 * dynwind.c (frame_print): Removed, use the default printer.
23 (WINDER_F_MARK, WINDER_MARK_P, winder_mark): New.
24 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New. Use above
25 to protect SCM values.
26
27 * dynwind.h (SCM_F_WIND_EXPLICITELY,
28 SCM_F_WIND_EXPLICITLY): It's "explicitly" not "explicitely", damn.
29 Changed all uses.
30 (scm_on_unwind_with_scm, scm_on_rewind_with_scm): New.

43 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
44 New.
45 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
46 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
47 function when the outermost wind point has been reached. The
48 latter is used to copy a continuation stack at the right time.
49 scm_dowinds remains available.
50 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
51 tc16_guard, guards_print): Removed.

57 rewinding.
58 (scm_dynthrow): Do not call scm_dowinds, this is now done by
59 copy_stack_and_call.

441a25d9
KR		 612004-01-04 Kevin Ryde <user42@zip.com.au>
62
63 * numbers.c (scm_less_p): Don't convert frac to float for compares,
dab514a8 64 can give bad results due to rounding.
441a25d9 65
e0499207
KR		 66 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
67 setzone/restorezone protection for DOS.
68
89fcf1b4
MV		 692003-12-26 Marius Vollmer <mvo@zagadka.de>
70

75
76 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
77
78 * numbers.c (scm_make_ratio): Check for numerator equal to
79 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
80 giving integer -1.
81
82 * numbers.c (scm_real_part): Return fraction unchanged rather than
83 converting to flonum.
84
2d0b85ac
DH		 852003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
86
87 * modules.c (module_variable): Fixed (and thus simplified) the
88 definition of SCM_BOUND_THING_P to reflect the fact that since
89 after the 1.4 series of guile, obarrays only hold variable
90 objects.
91
2297981d
MV		 922003-11-30 Marius Vollmer <mvo@zagadka.de>
93
94 * numbers.c (scm_logand): It's "#b...", not "#\b...".
95
96 From Paul Jarc:
97
98 * read.c (scm_lreadr): Signal an error for invalid escape
99 sequences in strings. Code cleanups too.
100
101 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
102 writing control characters in strings.
103
1042003-11-21 Marius Vollmer <mvo@zagadka.de>
105
106 * ports.c (scm_drain_input): Bug fix: only access the port after
107 checking that it indeed is one.
108
5c264007
DH		 1092003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
110
111 * eval.c (s_bad_define): New static identifier.
112
113 (m_body): Fixed comment.
114
115 (scm_m_define): Don't generate memoized code for definitions that
116 are not on the top level. As a consequence, no memoized code at
117 all is generated for definitions any more: Top level definitions
118 are executed immediately during memoization and internal
119 definitions are handled separately in m_expand_body.
120
121 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
122 definitions. Consequently, there is no unmemoizing code any more
123 that might modify the environment. Thus, the old scm_unmemocopy
124 is removed and the old unmemocopy is renamed to scm_unmemocopy.
125
126 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
127 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
128 over SCM_NIMP in places, where the argument is known to be part of
129 a proper list.
130
018d4730
KR		 1312003-11-21 Kevin Ryde <user42@zip.com.au>
132
133 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
134 for bignums.
135
136 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
137 to share some shifting.
138
139 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
140 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
141 since gc does this.
142

MV		 1432003-11-19 Marius Vollmer <mvo@zagadka.de>
144
fb16d26e
MV		 145 * numbers.c (scm_make_ratio): Rewritten to have a simpler
146 structure. Previously, not all cases with a negative denominator
147 were covered.
148
4bca30d8
MV		 149 * numbers.c (mem2decimal_from_point): use scm_divide instead of
150 scm_divide2real when forming the fractional part. This allows
151 "#e1.2" to yield 6/5.
152
153 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
154 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
155 fractions were equal to each other regardless of value. Ooops.
156
157 * numbers.c (scm_rationalize): Return an inexact result when given
158 inexact arguments.
159
160 * numbers.c (scm_exact_p, scm_inexact_p): Throw error for
161 non-numbers.

197
198 * gc-mark.c (scm_gc_mark_dependencies): Handle fractions.
199
200 * gc-card.c (scm_i_sweep_card): Include scm_tc16_fraction as a
201 case in the switch, but do nothing for now.
202
203 * eval.c (SCM_CEVAL, SCM_APPLY, call_dsubr_1): Convert fractions
204 to doubles when calling 'dsubr' functions.
205
206 * eq.c (scm_eqv_p, scm_equal_p): Handle fractions.
207
28fda544
RB		 2082003-11-18 Rob Browning <rlb@defaultvalue.org>
209
210 * gen-scmconfig.c (main): remove public definition of
211 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
212 direct typedef of long_long and ulong_long inside deprecated block
213 when appropriate.
214
215 * deprecated.h: move long_long and ulong_long definitions to
216 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
217 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

MV		 226 (scm_m_generalized_set_x): Use ASSERT_SYNTAX_2 instead of
227 SCM_ASSYNT.
b58e7420

230 the "-e" option instead of scm_str2symbol. This allows things
231 like (@ ...) to be specified for the entry point.

269
270 (canonicalize_define, scm_m_define): The check for a bad

633 This set of patches eliminates the dependency between the
634 implementation of evaluator specific memoization codes and special
635 constants like #f, '() etc. ('flags'), which are not evaluator
636 specific. The goal is to remove definitions of evaluator
637 memoization codes completely from the public interface. This will
638 make it possible to experiment more freely with optimizations of
639 guile's internal representation of memoized code.
640
641 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
642
643 * print.c (iflagnames): New array, holding the printed names of
644 guile's special constants ('flags').
645
646 (scm_isymnames): Now holds only the printed names of the
647 memoization codes.
648
649 (scm_iprin1): Separate the handling of memoization codes and
650 guile's special constants.

675 The typecode of the former 14th short instruction is now used to
676 represent long instructions. Changed some comments to reflect
677 this fact.
678
679 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
680 previously used by SCM_IM_DEFINE.
681
682 (SCM_IM_DEFINE): Turned into a long instruction.
683
684 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
685 instruction.
686
687 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
688 code that is separate from all instructions, one level of dispatch
689 for long instructions can be eliminated.

720 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
721 0.0==some_expression to some_expression==0.0. The latter is
722 better readable. The former is preferred by some people, since it
723 leads to a compiler error when confusing == with =. However, when
724 using gcc, a warning will be issued if in an if-statement an
725 assigment appears. Since many Guile developers are using gcc,
726 such errors will not remain unnoticed anyway. We can therefore
727 focus on better readability.

1257
1258 The purpose of this patch is to make guile's internal memoizers
1259 distinguishable from memoizing macros created on the scheme level
1260 or from user provided primitive memoizing macros. The reason is,
1261 that the internal memoizers are the only ones that are allowed to
1262 transform their scheme input into memoizer byte code, while all
1263 other memoizing macros may only transform scheme code into new
1264 scheme code.
1265
1266 To achieve this, a new macro type 'builtin-macro!' is introduced.
1267 Currently, 'builtin-macro!'s are handled as memoizing macros, but
1268 this will change when the memoizer and executor are separated.
1269

1369 This set of patches contains no functional changes, only debatable
1370 minor stylistic ones. Still, in order to prepare a patch between
1371 my local copy and the CVS version, I decided to submit the changes
1372 below. Then, the patch will hopefully only contain relevant
1373 modifications :-)
1374

1376
1377 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):

1412
1413 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
1414 arithmetics with index arithmetics. Changed quicksort to work on
1415 an array of SCM values instead of an array of characters. Avoid
1416 bytewise copying of SCM elements. Avoid allocating memory on the
1417 stack with alloca. Fixed some comments.

1439 their inclusion into the lib dependent of the
1440 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.

2101 running gen-scmconfig.h and capturing its output. gen-scmconfig
2102 uses config.h and the configure.in generated gen-scmconfig.h to
2103 decide what to output. See gen-scmconfig.c for details.
2104 (noinst_PROGRAMS): add gen-scmconfig.
2105 (gen_scmconfig_SOURCES): new variable.
2106 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
2107 cross-compiling right.
2108 (scmconfig.h): build scmconfig.h from gen-scmconfig's output.
2109 (BUILT_SOURCES): add scmconfig.h.

MD		 2176 This fixes a serious GC bug, introduced during the latest
2177 reorganization of the GC, which disabled freeing of structs and

2194 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
2195 (current number of prehistory bindings; hashtable code will select
2196 a prime which is greater than this value).

MD		 2209 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
2210
2211 The following changes introduce the use of resizable hash tables
2212 throughout Guile. It also renames the old *-hash-table* functions
2213 to *-alist-vector* and places them, together with the rest of the
2214 weak vector support, in the module (ice-9 weak-vector). We should
2215 probably introduce a new, better, API for weak references, for
2216 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
2217 look like and are used like ordinary pairs.)
2218
2219 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,

2401 This change makes it possible for one thread to do lazy sweeping
2402 while other threads are running. Now only the mark phase need to
2403 have all threads asleep. We should look further into this issue.
2404 Presently, I've put the locking of scm_i_sweep_mutex at
2405 "conservative" places due to my current lack of knowledge about
2406 the garbage collector. Please feel free to restrict these regions
2407 further to allow for maximal parallelism!
2408
2409 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
2410
2411 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
2412 scm_gc_register_collectable_memory): Substitute locking of
2413 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
2414 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
2415 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
2416 the single-thread section (which now only contains the mark
2417 phase).
2418 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
2419 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
2420
2421 * threads.c (gc_section_mutex): Removed.

2531 * threads.c (create_thread): Remember root object until the handle
2532 of the new thread is on all_threads list.
2533
2534 * root.c (scm_make_root): Moved copying of fluids until after
2535 creation of root handle so that the fluids are GC protected. Also
2536 removed the critical section.

2577 These changes remove scm_ints_disabled (which hasn't has any
2578 effect in Guile for quite some time).
2579
2580 * async.c, error.h (scm_ints_disabled): Removed.
2581

2586
2587 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
2588 critical section.

MD		 2597 These changes are the start of support for preemptive
2598 multithreading. Marius and I have agreed that I commit this code
2599 into the repository although it isn't thoroughly tested and surely
2600 introduces many bugs. The bugs should only be exposed when using
2601 threads, though. Signalling and error handling for threads is
2602 very likely broken. Work on making the implementation cleaner and
2603 more efficient is needed.
2604
2605 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
2606 (SCM_NONREC_CRITICAL_SECTION_START,
2607 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
2608 SCM_REC_CRITICAL_SECTION_END): New macros.
2609 (SCM_CRITICAL_SECTION_START/END): Defined here.
2610
2611 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
2612 the three calls to scm_m_expand_body.
2613
2614 * gc.h: #include "libguile/pthread-threads.h";
2615 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
2616
2617 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
2618 scm_t_key;
2619
2620 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
2621 access.
2622
2623 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
2624
2625 * gc-freelist.c, threads.c (really_launch): Use
2626 SCM_FREELIST_CREATE.
2627
2628 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
2629
2630 * gc.c (scm_i_expensive_validation_check, scm_gc,
2631 scm_gc_for_newcell): Put threads to sleep before doing GC-related
2632 heap administration so that those pieces of code are executed
2633 single-threaded. We might consider rewriting these code sections
2634 in terms of a "call_gc_code_singly_threaded" construct instead of
2635 calling the pair of scm_i_thread_put_to_sleep () and
2636 scm_i_thread_wake_up (). Also, we would want to have as many of
2637 these sections eleminated.
2638
2639 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
2640
2641 * inline.h: #include "libguile/threads.h"
2642
2643 * pthread-threads.h: Macros now conform more closely to the
2644 pthreads interface. Some of them now take a second argument.
2645
2646 * threads.c, threads.h: Many changes.

2657 (SCM_MICRO_VERSION): use @--@ substitution now.
2658 (scm_effective_version): new function prototype.

2661 effective-version.
2662
2663 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
2664 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
2665 SCM_LIBRARY_DIR.
2666 (version.h): generate this here rather than configure.in. This
2667 approach tracks source edits better (i.e. more immediately).
2668 Might be worth considering for other .in files too.

2672 Reorganized thread package selection. A thread package now only
2673 implements a small set of pthread like functions and Guile
2674 implements the rest on top of that. Guile's implementation is
2675 what the "coop-pthreads" package has been previously. Support for
2676 "coop" threads has been removed until I get time to add it again.
2677
2678 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
2679 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
2680 null-threads.c, coop-pthreads.c.
2681 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
2682 pthread-threads.h.
2683
2684 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
2685
2686 * threads.h: Do not include "libguile/coop-defs.h". Include
2687 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
2688 (previously deprecated) C level thread API prototypes. They are
2689 now in the thread package specific headers, "null-threads.h" and
2690 "pthread-threads.h".
2691 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
2692 New.
2693 (scm_threads_init): Removed.
2694 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
2695 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
2696 SCM_I_THREAD_SWITCH_COUNT): Define here.
2697 (scm_single_thread_p): Removed.
2698 (scm_call_with_new_thread): Take two args directly instead of list
2699 of two args.
2700 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
2701 SCM_SET_THREAD_LOCAL_DATA): Define here.
2702
2703 * threads.c: Merged with "coop-pthreads.c".
2704
2705 * null-threads.h: Implement pthread-like API as a set of macros.
2706
2707 * pthread-threads.h: New, implement pthread-like API by deferring
2708 to pthread itself.
2709
2710 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
2711 has been lost in the reorganization.

2715 The following change makes it possible to move procedure
2716 application dispatch outside inner loops. The motivation was
2717 clean implementation of efficient replacements of R5RS primitives
2718 in SRFI-1.
2719
2720 The semantics is clear: scm_trampoline_N returns an optimized
2721 version of scm_call_N (or NULL if the procedure isn't applicable
2722 on N args).
2723
2724 Applying the optimization to map and for-each increases efficiency
2725 noticeably. For example, (map abs ls) is 8 times faster than
2726 before.
2727
2728 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
2729
2730 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
2731
2732 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
2733 (map, for-each): Handle also application on two args as a special
2734 case; Use trampolines.
2735
2736 Other changes:
2737
2738 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
2739 (subr2oless): Removed.
2740 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
2741 vector GC protected.
2742
2743 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
2744 scm_out_of_range.

2782 part of the API, otherwise it's difficult to write Guile
2783 extensions using non-blocking I/O => moved #include
2784 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.

2852 scm_delq_spine_x, really_install_handler, install_handler): New
2853 scheme for triggering signal handlers, to simplify take_signal.
2854 (take_signal): Simplified, to avoid race conditions.
2855 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
2856 hasn't exited yet.
2857
2858 * async.c (scm_async_click): Reset pending_asyncs, handle
2859 signal_asyncs. Don't set cdr of a non-signal async to #f.
2860 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
2861 always. Set pending_asyncs.
2862 (scm_system_async_mark_for_thread): Check that thread has not
2863 exited.
2864 (scm_unmask_signals, decrease_block): Call scm_async_click after
2865 block_asyncs becomes zero.

2882 USE_COPT_THREADS to not protect the slot initializers.
2883
2884 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
2885 because threads need to be initialized before the stack, but
2886 gsubrs such as scm_timed_condition_variable_wait can only be
2887 created later.
2888
2889 * threads.h: Include "coop-pthreads.h" when requested.
2890 (scm_threads_make_mutex, scm_threads_lock_mutex,
2891 scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were

2907 (scm_try_mutex, scm_broadcast_condition_variable): Newly
2908 registered procedures.
2909 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
2910 Use the latter as the procedure for "wait-condition-variable",
2911 thus offering a optional timeout parameter to Scheme.
2912 (scm_wait_condition_variable): Implement in terms of
2913 scm_timed_wait_condition_variable.
2914 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,

2917 scm_cond_broadcast, scm_cond_destroy): Implement in terms of
2918 scm_make_mutex, etc, and deprecate.
2919 (scm_init_threads): Do not create smobs, leave this to
2920 scm_threads_init. Do not include "threads.x" file.

2931 handled by threads.{h,c}.
2932
2933 * null-threads.c (scm_null_mutex, scm_null_cond): Define here.
