2
3 * eval.c (s_bad_define): New static identifier.
4
5 (m_body): Fixed comment.
6
7 (scm_m_define): Don't generate memoized code for definitions that
8 are not on the top level. As a consequence, no memoized code at
9 all is generated for definitions any more: Top level definitions
10 are executed immediately during memoization and internal
11 definitions are handled separately in m_expand_body.
12
13 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
14 definitions. Consequently, there is no unmemoizing code any more
15 that might modify the environment. Thus, the old scm_unmemocopy
16 is removed and the old unmemocopy is renamed to scm_unmemocopy.
17
18 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
19 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
20 over SCM_NIMP in places, where the argument is known to be part of
21 a proper list.

KR		 232003-11-21 Kevin Ryde <user42@zip.com.au>
24
25 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
26 for bignums.
27
28 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
29 to share some shifting.
30
31 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
32 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
33 since gc does this.

MV		 37 * numbers.c (scm_make_ratio): Rewritten to have a simpler
38 structure. Previously, not all cases with a negative denominator
39 were covered.
40
4bca30d8
MV		 41 * numbers.c (mem2decimal_from_point): use scm_divide instead of
42 scm_divide2real when forming the fractional part. This allows
43 "#e1.2" to yield 6/5.
44
45 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
46 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
47 fractions were equal to each other regardless of value. Ooops.
48
49 * numbers.c (scm_rationalize): Return an inexact result when given
50 inexact arguments.
51
52 * numbers.c (scm_exact_p, scm_inexact_p): Throw error for
53 non-numbers.

71 New exact functions that replace the inexact 'dsubr'
72 implementations.

91
92 * gc-card.c (scm_i_sweep_card): Include scm_tc16_fraction as a
93 case in the switch, but do nothing for now.
94
95 * eval.c (SCM_CEVAL, SCM_APPLY, call_dsubr_1): Convert fractions
96 to doubles when calling 'dsubr' functions.
97
98 * eq.c (scm_eqv_p, scm_equal_p): Handle fractions.
99

RB		 1002003-11-18 Rob Browning <rlb@defaultvalue.org>
101
102 * gen-scmconfig.c (main): remove public definition of
103 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
104 direct typedef of long_long and ulong_long inside deprecated block
105 when appropriate.
106
107 * deprecated.h: move long_long and ulong_long definitions to
108 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
109 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

119 SCM_ASSYNT.
b58e7420

491 This set of patches introduces a new tc7 code scm_tc7_number for
492 numbers. Bignums, reals and complex numbers are turned from smobs

524
525 This set of patches eliminates the dependency between the
526 implementation of evaluator specific memoization codes and special
527 constants like #f, '() etc. ('flags'), which are not evaluator
528 specific. The goal is to remove definitions of evaluator
529 memoization codes completely from the public interface. This will
530 make it possible to experiment more freely with optimizations of
531 guile's internal representation of memoized code.
532
533 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
534
535 * print.c (iflagnames): New array, holding the printed names of
536 guile's special constants ('flags').
537
538 (scm_isymnames): Now holds only the printed names of the
539 memoization codes.
540
541 (scm_iprin1): Separate the handling of memoization codes and
542 guile's special constants.
543
544 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
545 SCM_IFLAGNUM): new

552 values.

565
566 * tags.h: Reduced the number of short instructions from 14 to 13.
567 The typecode of the former 14th short instruction is now used to
568 represent long instructions. Changed some comments to reflect
569 this fact.
570
571 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
572 previously used by SCM_IM_DEFINE.
573
574 (SCM_IM_DEFINE): Turned into a long instruction.
575
576 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
577 instruction.
578
579 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
580 code that is separate from all instructions, one level of dispatch
581 for long instructions can be eliminated.
582
583 * print.c (scm_isymnames): Removed some commented code.

610 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
611
612 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
613 0.0==some_expression to some_expression==0.0. The latter is
614 better readable. The former is preferred by some people, since it
615 leads to a compiler error when confusing == with =. However, when
616 using gcc, a warning will be issued if in an if-statement an
617 assigment appears. Since many Guile developers are using gcc,
618 such errors will not remain unnoticed anyway. We can therefore
619 focus on better readability.

869 * eval.c: Partially undid my patch from 2003-05-31. This patch
870 caused the segfault referenced in the previous changelog entry.

DH		 8722003-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
873
874 * tags.h: Fixed comment about the immediate type code layout.
875
876 * eval.c: Fixed handling of non-special instructions. Without
877 this patch, guile will segfault on (#\0) and similar instructions.

881 * numbers.c (scm_max, scm_min): For inum, bignum and real, if other
882 operand is NaN, then return NaN. Also avoid passing NaN to mpz_cmp_d.
883
e418bd7c
KR		 884 * read.c (scm_input_error): Pass arg list parameter to scm_error_scm,
885 rather than SCM_EOL. Needed by "Unknown # object" case in scm_lreadr.

888
889 * __scm.h, gc-card.c (SCM_DEBUG_DEBUGGER_SUPPORT,
890 SCM_DEBUG_DEBUGGING_SUPPORT): Renamed macro
891 SCM_DEBUG_DEBUGGER_SUPPORT to SCM_DEBUG_DEBUGGING_SUPPORT and
892 generalized it to apply not only to C level functions but also to
893 scheme level functions.
894
895 * debug.c, debug.h, eval.c (make-iloc, scm_make_iloc, iloc?,
896 scm_iloc_p, dbg-make-iloc, scm_dbg_make_iloc, dbg-iloc?,
897 scm_dbg_iloc_p): Moved functions scm_make_iloc, scm_iloc_p to
898 eval.c, made them available under SCM_DEBUG_DEBUGGING_SUPPORT == 1
899 only and renamed them to scm_dbg_make_iloc, scm_dbg_iloc_p,
900 respectively.
901
902 * deprecated.h, eval.c, eval.h (SCM_ILOC00, SCM_IDINC,
903 SCM_IDSTMSK): Deprecated. The macro definitions are moved from
904 eval.h into eval.c and a copy is placed into deprecated.h.
905
906 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
907 into eval.c. This definition was not part of the API in any
908 officially released version of guile and thus does not need to go
909 through a phase of deprecation.

917 In deprecated.c the original definitions are copied.
918
d0624e39
DH		 919 * deprecated.h, eval.c, eval (SCM_EVALIM2, SCM_EVALIM, SCM_XEVAL,
920 SCM_XEVALCAR): Deprecated. The macro definitions are moved from
e90c3a89
DH		 921 eval.h into eval.c and a copy (slightly modified to work in user
922 code) is placed into deprecated.h.

929 This set of patches separates the representation of the cxr family
930 of functions (car, cdr etc.) from the dsubr family of functions
931 (i. e. functions that take a double precision floating point
932 argument). Further, the algorithm for handling the cxr function
933 is improved.

937 ceil, sqrt, fabs, exp, log, sin, cos, tan, asin, acos, atan, sinh,
938 cosh, tanh), objects.c (scm_class_of), procprop.c
939 (scm_i_procedure_arity), ramap.c (scm_array_map_x), tags.h
940 (scm_tc7_dsubr, scm_tcs_subrs): Introduce scm_tc7_dsubr as new
941 typecode for the dsubr family of functions.
942
943 * ramap.c (ramap_cxr, ramap_dsubr): Renamed ramap_cxr to
944 ramap_dsubr.
945
946 * eval.c (SCM_CEVAL, SCM_APPLY, call_cxr_1), pairs.c
947 (scm_init_pairs): Make use of the (now usable) second cell element
948 of a scm_tc7_cxr function to implement the cxr family of functions
949 more efficiently.

990 mingw32 build.
991
992 * modules.c (s_scm_module_import_interface): Renamed local
993 variable interface to _interface. Seems like 'interface'
994 is a special compiler directive for the mingw32 compiler.
995
996 * mkstemp.c: Provide prototype to avoid compiler warning.
997
998 * load.c (s_scm_search_path): Fixed absolute and relative

1150 The purpose of this patch is to make guile's internal memoizers
1151 distinguishable from memoizing macros created on the scheme level
1152 or from user provided primitive memoizing macros. The reason is,
1153 that the internal memoizers are the only ones that are allowed to
1154 transform their scheme input into memoizer byte code, while all
1155 other memoizing macros may only transform scheme code into new
1156 scheme code.
1157
1158 To achieve this, a new macro type 'builtin-macro!' is introduced.
1159 Currently, 'builtin-macro!'s are handled as memoizing macros, but
1160 this will change when the memoizer and executor are separated.
1161
1162 * macros.[ch] (scm_i_makbimacro): New.
1163
1164 * macros.h (SCM_BUILTIN_MACRO_P): New.
1165
1166 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
1167
1168 * eval.c, goops.c: All of guile's primitive memoizing macros are
1169 primitive builtin-macros now.
1170
1171 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
1172 builtin-macros are handled equally to memoizing macros.

1261 This set of patches contains no functional changes, only debatable
1262 minor stylistic ones. Still, in order to prepare a patch between

1306 arithmetics with index arithmetics. Changed quicksort to work on
1307 an array of SCM values instead of an array of characters. Avoid
1308 bytewise copying of SCM elements. Avoid allocating memory on the
1309 stack with alloca. Fixed some comments.

1331 their inclusion into the lib dependent of the
1332 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.

2104 throughout Guile. It also renames the old *-hash-table* functions
2105 to *-alist-vector* and places them, together with the rest of the
2106 weak vector support, in the module (ice-9 weak-vector). We should
2107 probably introduce a new, better, API for weak references, for
2108 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
2109 look like and are used like ordinary pairs.)
2110
2111 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
2112 leaf_environment_fold, obarray_remove_all): Use hashtable
2113 accessors.

2147 SCM_WVECT_NOSCAN_P): New macros.

2293 This change makes it possible for one thread to do lazy sweeping
2294 while other threads are running. Now only the mark phase need to
2295 have all threads asleep. We should look further into this issue.
2296 Presently, I've put the locking of scm_i_sweep_mutex at
2297 "conservative" places due to my current lack of knowledge about
2298 the garbage collector. Please feel free to restrict these regions
2299 further to allow for maximal parallelism!
2300
2301 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
2302
2303 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
2304 scm_gc_register_collectable_memory): Substitute locking of
2305 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
2306 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
2307 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
2308 the single-thread section (which now only contains the mark
2309 phase).
2310 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
2311 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
2312
2313 * threads.c (gc_section_mutex): Removed.

2376
2377 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with

2379 to scm_m_expand_body.

MD		 2489 These changes are the start of support for preemptive
2490 multithreading. Marius and I have agreed that I commit this code
2491 into the repository although it isn't thoroughly tested and surely
2492 introduces many bugs. The bugs should only be exposed when using
2493 threads, though. Signalling and error handling for threads is
2494 very likely broken. Work on making the implementation cleaner and
2495 more efficient is needed.

2523 scm_gc_for_newcell): Put threads to sleep before doing GC-related
2524 heap administration so that those pieces of code are executed
2525 single-threaded. We might consider rewriting these code sections
2526 in terms of a "call_gc_code_singly_threaded" construct instead of
2527 calling the pair of scm_i_thread_put_to_sleep () and
2528 scm_i_thread_wake_up (). Also, we would want to have as many of
2529 these sections eleminated.
2530
2531 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
2532
2533 * inline.h: #include "libguile/threads.h"
2534
2535 * pthread-threads.h: Macros now conform more closely to the
2536 pthreads interface. Some of them now take a second argument.
2537
2538 * threads.c, threads.h: Many changes.

2548 (SCM_MINOR_VERSION): use @--@ substitution now.
2549 (SCM_MICRO_VERSION): use @--@ substitution now.
2550 (scm_effective_version): new function prototype.

2553 effective-version.
2554
2555 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
2556 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
2557 SCM_LIBRARY_DIR.
2558 (version.h): generate this here rather than configure.in. This
2559 approach tracks source edits better (i.e. more immediately).
2560 Might be worth considering for other .in files too.

MV		 25622002-12-02 Marius Vollmer <mvo@zagadka.ping.de>
2563
2564 Reorganized thread package selection. A thread package now only
2565 implements a small set of pthread like functions and Guile
2566 implements the rest on top of that. Guile's implementation is
2567 what the "coop-pthreads" package has been previously. Support for
2568 "coop" threads has been removed until I get time to add it again.
2569
2570 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
2571 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
2572 null-threads.c, coop-pthreads.c.
2573 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
2574 pthread-threads.h.
2575
2576 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
2577
2578 * threads.h: Do not include "libguile/coop-defs.h". Include
2579 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
2580 (previously deprecated) C level thread API prototypes. They are
2581 now in the thread package specific headers, "null-threads.h" and
2582 "pthread-threads.h".
2583 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
2584 New.
2585 (scm_threads_init): Removed.
2586 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
2587 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
2588 SCM_I_THREAD_SWITCH_COUNT): Define here.
2589 (scm_single_thread_p): Removed.
2590 (scm_call_with_new_thread): Take two args directly instead of list
2591 of two args.
2592 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
2593 SCM_SET_THREAD_LOCAL_DATA): Define here.
2594
2595 * threads.c: Merged with "coop-pthreads.c".
2596
2597 * null-threads.h: Implement pthread-like API as a set of macros.
2598
2599 * pthread-threads.h: New, implement pthread-like API by deferring
2600 to pthread itself.
2601
2602 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
2603 has been lost in the reorganization.

2606
2607 The following change makes it possible to move procedure
2608 application dispatch outside inner loops. The motivation was
2609 clean implementation of efficient replacements of R5RS primitives
2610 in SRFI-1.
2611
2612 The semantics is clear: scm_trampoline_N returns an optimized
2613 version of scm_call_N (or NULL if the procedure isn't applicable
2614 on N args).
2615
2616 Applying the optimization to map and for-each increases efficiency
2617 noticeably. For example, (map abs ls) is 8 times faster than
2618 before.
2619
2620 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
2621
2622 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
2623
2624 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
2625 (map, for-each): Handle also application on two args as a special
2626 case; Use trampolines.
2627
2628 Other changes:
2629
2630 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
2631 (subr2oless): Removed.
2632 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
2633 vector GC protected.
2634
2635 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
2636 scm_out_of_range.

2659 scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
2660 scm_system_module_env_p): Don't compare SCM values with C
2661 operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
2662 over SCM_NFALSEP.

MD		 26712002-11-14 Mikael Djurfeldt <mdj@linnaeus>
2672
2673 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
2674 part of the API, otherwise it's difficult to write Guile
2675 extensions using non-blocking I/O => moved #include
2676 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
2677
2678 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
2679 s_unlock_mutex.

2684 are defined in configure.in.

2687 is only for declarations.

2713 SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile.
2714

2734 start testing it now.
2735
2736 * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly
2737 defined when HAVE_RESTARTABLE_SYSCALLS is not defined.
2738 (HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS
2739 is defined.

2742
2743 * scmsigs.c (signal_cell_handlers, install_handler_data,
2744 scm_delq_spine_x, really_install_handler, install_handler): New
2745 scheme for triggering signal handlers, to simplify take_signal.
2746 (take_signal): Simplified, to avoid race conditions.
2747 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
2748 hasn't exited yet.
2749
2750 * async.c (scm_async_click): Reset pending_asyncs, handle
2751 signal_asyncs. Don't set cdr of a non-signal async to #f.
2752 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
2753 always. Set pending_asyncs.
2754 (scm_system_async_mark_for_thread): Check that thread has not
2755 exited.
2756 (scm_unmask_signals, decrease_block): Call scm_async_click after
2757 block_asyncs becomes zero.
2758
2759 * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of
2760 active_asyncs.

2763 fields.

2772
2773 * inline.h (scm_cell, scm_double_cell): Also allow
2774 USE_COPT_THREADS to not protect the slot initializers.
2775
2776 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
2777 because threads need to be initialized before the stack, but
2778 gsubrs such as scm_timed_condition_variable_wait can only be
2779 created later.
2780
2781 * threads.h: Include "coop-pthreads.h" when requested.
2782 (scm_threads_make_mutex, scm_threads_lock_mutex,
2783 scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were

2800 registered procedures.
2801 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
2802 Use the latter as the procedure for "wait-condition-variable",
2803 thus offering a optional timeout parameter to Scheme.
2804 (scm_wait_condition_variable): Implement in terms of
2805 scm_timed_wait_condition_variable.
2806 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,
2807 scm_mutex_unlock, scm_mutex_destroy, scm_cond_init,
2808 scm_cond_wait, scm_cond_timedwait, scm_cond_signal,
2809 scm_cond_broadcast, scm_cond_destroy): Implement in terms of
2810 scm_make_mutex, etc, and deprecate.
2811 (scm_init_threads): Do not create smobs, leave this to
2812 scm_threads_init. Do not include "threads.x" file.
2813 (scm_init_thread_procs): New, include "threads.x" here.
2814
2815 * null-threads.h (scm_null_mutex, scm_null_mutex_init,

2821 scm_cond_wait, scm_cond_signal, scm_cond_broadcast,
2822 scm_cond_destory): Do not define, they are now deprecated and
2823 handled by threads.{h,c}.
2824
2825 * null-threads.c (scm_null_mutex, scm_null_cond): Define here.
2826 (scm_threads_init): Create smobs here, using the appropriate
2827 sizes.
