MV		 12004-01-05 Marius Vollmer <mvo@zagadka.de>
2
3 * ports.h, ports.c (scm_with_current_input_port,
4 scm_with_current_output_port, scm_with_current_error_port): New.
5
6 * async.h, async.c (scm_with_blocked_asyncs,
7 scm_with_unblocked_asyncs): New.

MV		 92004-01-03 Marius Vollmer <mvo@zagadka.de>
10
11 * dynwind.h, scm_dynwind.c (scm_t_frame_flags, scm_t_wind_flags,
12 scm_begin_frame, scm_end_frame, scm_on_unwind, scm_on_rewind):
13 New.
14 (scm_dowinds, scm_i_dowinds): scm_dowinds has been renamed to
15 scm_i_dowinds and extended to handle frames and to invoke a 'turn'
16 function when the outermost wind point has been reached. The
17 latter is used to copy a continuation stack at the right time.
18 scm_dowinds remains available.
19 (SCM_GUARDSP, SCM_BEFORE_GUARD, SCM_AFTER_GUARD, SCM_GUARD_DATA,
20 tc16_guard, guards_print): Removed.
21 (scm_internal_dynamic_wind): Reimplemented using frames.
22
23 * continuations.c (copy_stack): New, do only the stack copying
24 part of copy_stack_and_call.
25 (copy_stack_and_call): Copy the stack after unwinding and before
26 rewinding.
27 (scm_dynthrow): Do not call scm_dowinds, this is now done by
28 copy_stack_and_call.
29
441a25d9
KR		 302004-01-04 Kevin Ryde <user42@zip.com.au>
31
32 * numbers.c (scm_less_p): Don't convert frac to float for compares,
dab514a8 33 can give bad results due to rounding.
441a25d9 34
e0499207
KR		 35 * stime.c (scm_current_time, scm_gettimeofday): Add a comment about
36 setzone/restorezone protection for DOS.
37
89fcf1b4
MV		 382003-12-26 Marius Vollmer <mvo@zagadka.de>
39
40 * gen-scmconfig.h.in, gen-scmconfig.c: Arrange for scm_t_intmax
41 and scm_t_uintmax to be defined in scmconfig.h
42
caff34d4
KR		 432003-12-03 Kevin Ryde <user42@zip.com.au>
44
45 * numbers.c (scm_less_p): Remove spurious xisnan from frac+big case.
46
47 * numbers.c (scm_make_ratio): Check for numerator equal to
48 SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
49 giving integer -1.
50
51 * numbers.c (scm_real_part): Return fraction unchanged rather than
52 converting to flonum.
53
2d0b85ac
DH		 542003-11-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
55
56 * modules.c (module_variable): Fixed (and thus simplified) the
57 definition of SCM_BOUND_THING_P to reflect the fact that since
58 after the 1.4 series of guile, obarrays only hold variable
59 objects.
60
2297981d
MV		 612003-11-30 Marius Vollmer <mvo@zagadka.de>
62
63 * numbers.c (scm_logand): It's "#b...", not "#\b...".
64
65 From Paul Jarc:
66
67 * read.c (scm_lreadr): Signal an error for invalid escape
68 sequences in strings. Code cleanups too.
69
70 * print.c (scm_iprin1): use \xNN hexadecimal sequences when
71 writing control characters in strings.
72
732003-11-21 Marius Vollmer <mvo@zagadka.de>
74
75 * ports.c (scm_drain_input): Bug fix: only access the port after
76 checking that it indeed is one.
77
5c264007
DH		 782003-11-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
79
80 * eval.c (s_bad_define): New static identifier.
81
82 (m_body): Fixed comment.
83
84 (scm_m_define): Don't generate memoized code for definitions that
85 are not on the top level. As a consequence, no memoized code at
86 all is generated for definitions any more: Top level definitions
87 are executed immediately during memoization and internal
88 definitions are handled separately in m_expand_body.
89
90 (scm_unmemocopy, unmemocopy): Removed code for unmemoizing
91 definitions. Consequently, there is no unmemoizing code any more
92 that might modify the environment. Thus, the old scm_unmemocopy
93 is removed and the old unmemocopy is renamed to scm_unmemocopy.
94
95 (SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
96 memoized code. Call EVALCAR for continuations. Prefer !SCM_NULLP
97 over SCM_NIMP in places, where the argument is known to be part of
98 a proper list.
99
018d4730
KR		 1002003-11-21 Kevin Ryde <user42@zip.com.au>
101
102 * numbers.c (scm_abs): Allocate a new real only for negatives, as done
103 for bignums.
104
105 * numbers.c (scm_bit_extract): Use mpz functions, rearrange inum case
106 to share some shifting.
107
108 * numbers.c (scm_integer_expt): Don't mpz_init after scm_i_clonebig or
109 scm_i_mkbig, since they do so already. Don't mpz_clear a bignum SCM,
110 since gc does this.
111

MV		 1122003-11-19 Marius Vollmer <mvo@zagadka.de>
113
fb16d26e
MV		 114 * numbers.c (scm_make_ratio): Rewritten to have a simpler
115 structure. Previously, not all cases with a negative denominator
116 were covered.
117
4bca30d8
MV		 118 * numbers.c (mem2decimal_from_point): use scm_divide instead of
119 scm_divide2real when forming the fractional part. This allows
120 "#e1.2" to yield 6/5.
121
122 * numbers.c (scm_i_fraction_equalp): Do not treat the return value
123 of scm_equal_p as a C boolean, use SCM_FALSEP. Previously, all
124 fractions were equal to each other regardless of value. Ooops.
125
126 * numbers.c (scm_rationalize): Return an inexact result when given
127 inexact arguments.
128
129 * numbers.c (scm_exact_p, scm_inexact_p): Throw error for
130 non-numbers.

162 (scm_i_dbl2num, scm_i_fraction2double, scm_i_fraction_equalp,
163 scm_i_print_fraction): New prototypes.
164
165 * goops.c (create_standard_classes): Create "<fraction>" class.
166
167 * gc-mark.c (scm_gc_mark_dependencies): Handle fractions.
168
169 * gc-card.c (scm_i_sweep_card): Include scm_tc16_fraction as a
170 case in the switch, but do nothing for now.
171
172 * eval.c (SCM_CEVAL, SCM_APPLY, call_dsubr_1): Convert fractions
173 to doubles when calling 'dsubr' functions.
174
175 * eq.c (scm_eqv_p, scm_equal_p): Handle fractions.
176
28fda544
RB		 1772003-11-18 Rob Browning <rlb@defaultvalue.org>
178
179 * gen-scmconfig.c (main): remove public definition of
180 SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
181 direct typedef of long_long and ulong_long inside deprecated block
182 when appropriate.
183
184 * deprecated.h: move long_long and ulong_long definitions to
185 gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
186 and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

MV		 195 (scm_m_generalized_set_x): Use ASSERT_SYNTAX_2 instead of
196 SCM_ASSYNT.
b58e7420
MV		 197
198 * script.c (scm_compile_shell_switches): Use scm_c_read_string for
199 the "-e" option instead of scm_str2symbol. This allows things
200 like (@ ...) to be specified for the entry point.

601
602 This set of patches eliminates the dependency between the
603 implementation of evaluator specific memoization codes and special
604 constants like #f, '() etc. ('flags'), which are not evaluator
605 specific. The goal is to remove definitions of evaluator
606 memoization codes completely from the public interface. This will
607 make it possible to experiment more freely with optimizations of
608 guile's internal representation of memoized code.
609
610 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
611
612 * print.c (iflagnames): New array, holding the printed names of
613 guile's special constants ('flags').
614
615 (scm_isymnames): Now holds only the printed names of the
616 memoization codes.
617
618 (scm_iprin1): Separate the handling of memoization codes and
619 guile's special constants.
620
621 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,

643 * tags.h: Reduced the number of short instructions from 14 to 13.
644 The typecode of the former 14th short instruction is now used to
645 represent long instructions. Changed some comments to reflect
646 this fact.
647
648 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
649 previously used by SCM_IM_DEFINE.
650
651 (SCM_IM_DEFINE): Turned into a long instruction.
652
653 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
654 instruction.
655
656 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
657 code that is separate from all instructions, one level of dispatch
658 for long instructions can be eliminated.

688
689 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
690 0.0==some_expression to some_expression==0.0. The latter is
691 better readable. The former is preferred by some people, since it
692 leads to a compiler error when confusing == with =. However, when
693 using gcc, a warning will be issued if in an if-statement an
694 assigment appears. Since many Guile developers are using gcc,
695 such errors will not remain unnoticed anyway. We can therefore
696 focus on better readability.

1227 The purpose of this patch is to make guile's internal memoizers
1228 distinguishable from memoizing macros created on the scheme level
1229 or from user provided primitive memoizing macros. The reason is,
1230 that the internal memoizers are the only ones that are allowed to
1231 transform their scheme input into memoizer byte code, while all
1232 other memoizing macros may only transform scheme code into new
1233 scheme code.
1234
1235 To achieve this, a new macro type 'builtin-macro!' is introduced.
1236 Currently, 'builtin-macro!'s are handled as memoizing macros, but
1237 this will change when the memoizer and executor are separated.
1238
1239 * macros.[ch] (scm_i_makbimacro): New.

1244
1245 * eval.c, goops.c: All of guile's primitive memoizing macros are
1246 primitive builtin-macros now.
1247
1248 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
1249 builtin-macros are handled equally to memoizing macros.

1338 This set of patches contains no functional changes, only debatable
1339 minor stylistic ones. Still, in order to prepare a patch between
1340 my local copy and the CVS version, I decided to submit the changes
1341 below. Then, the patch will hopefully only contain relevant
1342 modifications :-)
1343

1345
1346 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
1347 Use NULL instead of 0 to indicate that a pointer is returned.
1348 Removed some misleading 'fall through' comments.

1380 (compare_function): Added.
1381
1382 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
1383 arithmetics with index arithmetics. Changed quicksort to work on
1384 an array of SCM values instead of an array of characters. Avoid
1385 bytewise copying of SCM elements. Avoid allocating memory on the
1386 stack with alloca. Fixed some comments.

1406 functions such that they check if the object is a non-immediate.
1407 Further, renamed identifiers to use the scm_dbg_ prefix and made
1408 their inclusion into the lib dependent of the
1409 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.

MD		 2145 This fixes a serious GC bug, introduced during the latest
2146 reorganization of the GC, which disabled freeing of structs and
2147 GOOPS objects:

MD		 2178 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
2179
2180 The following changes introduce the use of resizable hash tables
2181 throughout Guile. It also renames the old *-hash-table* functions
2182 to *-alist-vector* and places them, together with the rest of the
2183 weak vector support, in the module (ice-9 weak-vector). We should
2184 probably introduce a new, better, API for weak references, for
2185 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
2186 look like and are used like ordinary pairs.)
2187
2188 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,

2370 This change makes it possible for one thread to do lazy sweeping
2371 while other threads are running. Now only the mark phase need to
2372 have all threads asleep. We should look further into this issue.
2373 Presently, I've put the locking of scm_i_sweep_mutex at
2374 "conservative" places due to my current lack of knowledge about
2375 the garbage collector. Please feel free to restrict these regions
2376 further to allow for maximal parallelism!
2377
2378 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
2379
2380 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
2381 scm_gc_register_collectable_memory): Substitute locking of
2382 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
2383 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
2384 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
2385 the single-thread section (which now only contains the mark
2386 phase).
2387 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
2388 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
2389
2390 * threads.c (gc_section_mutex): Removed.

2516 (Now we have to make sure all calls to malloc/realloc are made
2517 through scm_malloc.)

2546 These changes remove scm_ints_disabled (which hasn't has any
2547 effect in Guile for quite some time).
2548
2549 * async.c, error.h (scm_ints_disabled): Removed.
2550
2551 * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1),
2552 root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK,
2553 SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled.
2554 (old_ints): Removed.
2555
2556 * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive
2557 critical section.
2558 (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and
2559 SCM_ALLOW_INTS.

MD		 2566 These changes are the start of support for preemptive
2567 multithreading. Marius and I have agreed that I commit this code
2568 into the repository although it isn't thoroughly tested and surely
2569 introduces many bugs. The bugs should only be exposed when using
2570 threads, though. Signalling and error handling for threads is
2571 very likely broken. Work on making the implementation cleaner and
2572 more efficient is needed.
2573
2574 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
2575 (SCM_NONREC_CRITICAL_SECTION_START,
2576 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
2577 SCM_REC_CRITICAL_SECTION_END): New macros.
2578 (SCM_CRITICAL_SECTION_START/END): Defined here.
2579
2580 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
2581 the three calls to scm_m_expand_body.
2582
2583 * gc.h: #include "libguile/pthread-threads.h";
2584 (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
2585
2586 * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
2587 scm_t_key;
2588
2589 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
2590 access.
2591
2592 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
2593
2594 * gc-freelist.c, threads.c (really_launch): Use
2595 SCM_FREELIST_CREATE.
2596
2597 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
2598
2599 * gc.c (scm_i_expensive_validation_check, scm_gc,
2600 scm_gc_for_newcell): Put threads to sleep before doing GC-related
2601 heap administration so that those pieces of code are executed
2602 single-threaded. We might consider rewriting these code sections
2603 in terms of a "call_gc_code_singly_threaded" construct instead of
2604 calling the pair of scm_i_thread_put_to_sleep () and
2605 scm_i_thread_wake_up (). Also, we would want to have as many of
2606 these sections eleminated.
2607
2608 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
2609
2610 * inline.h: #include "libguile/threads.h"
2611
2612 * pthread-threads.h: Macros now conform more closely to the
2613 pthreads interface. Some of them now take a second argument.
2614
2615 * threads.c, threads.h: Many changes.
2616
26172002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se>

2623
2624 * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now.
2625 (SCM_MINOR_VERSION): use @--@ substitution now.
2626 (SCM_MICRO_VERSION): use @--@ substitution now.
2627 (scm_effective_version): new function prototype.
2628
2629 * version.c (scm_effective_version): new function, also add
2630 effective-version.
2631
2632 * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION.
2633 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
2634 SCM_LIBRARY_DIR.
2635 (version.h): generate this here rather than configure.in. This
2636 approach tracks source edits better (i.e. more immediately).
2637 Might be worth considering for other .in files too.

2641 Reorganized thread package selection. A thread package now only
2642 implements a small set of pthread like functions and Guile
2643 implements the rest on top of that. Guile's implementation is
2644 what the "coop-pthreads" package has been previously. Support for
2645 "coop" threads has been removed until I get time to add it again.
2646
2647 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
2648 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
2649 null-threads.c, coop-pthreads.c.
2650 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
2651 pthread-threads.h.
2652
2653 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
2654
2655 * threads.h: Do not include "libguile/coop-defs.h". Include
2656 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
2657 (previously deprecated) C level thread API prototypes. They are
2658 now in the thread package specific headers, "null-threads.h" and
2659 "pthread-threads.h".
2660 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
2661 New.
2662 (scm_threads_init): Removed.
2663 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
2664 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
2665 SCM_I_THREAD_SWITCH_COUNT): Define here.
2666 (scm_single_thread_p): Removed.
2667 (scm_call_with_new_thread): Take two args directly instead of list
2668 of two args.
2669 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
2670 SCM_SET_THREAD_LOCAL_DATA): Define here.
2671
2672 * threads.c: Merged with "coop-pthreads.c".
2673
2674 * null-threads.h: Implement pthread-like API as a set of macros.
2675
2676 * pthread-threads.h: New, implement pthread-like API by deferring
2677 to pthread itself.
2678
2679 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
2680 has been lost in the reorganization.

2684 The following change makes it possible to move procedure
2685 application dispatch outside inner loops. The motivation was
2686 clean implementation of efficient replacements of R5RS primitives
2687 in SRFI-1.
2688
2689 The semantics is clear: scm_trampoline_N returns an optimized
2690 version of scm_call_N (or NULL if the procedure isn't applicable
2691 on N args).
2692
2693 Applying the optimization to map and for-each increases efficiency
2694 noticeably. For example, (map abs ls) is 8 times faster than
2695 before.
2696
2697 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
2698
2699 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
2700
2701 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
2702 (map, for-each): Handle also application on two args as a special
2703 case; Use trampolines.
2704
2705 Other changes:
2706
2707 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
2708 (subr2oless): Removed.
2709 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
2710 vector GC protected.
2711
2712 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
2713 scm_out_of_range.

2750 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
2751 part of the API, otherwise it's difficult to write Guile
2752 extensions using non-blocking I/O => moved #include
2753 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.

2800 is defined.

2821 scm_delq_spine_x, really_install_handler, install_handler): New
2822 scheme for triggering signal handlers, to simplify take_signal.
2823 (take_signal): Simplified, to avoid race conditions.
2824 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
2825 hasn't exited yet.
2826
2827 * async.c (scm_async_click): Reset pending_asyncs, handle
2828 signal_asyncs. Don't set cdr of a non-signal async to #f.
2829 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
2830 always. Set pending_asyncs.
2831 (scm_system_async_mark_for_thread): Check that thread has not
2832 exited.
2833 (scm_unmask_signals, decrease_block): Call scm_async_click after
2834 block_asyncs becomes zero.

2851 USE_COPT_THREADS to not protect the slot initializers.
2852
2853 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
2854 because threads need to be initialized before the stack, but
2855 gsubrs such as scm_timed_condition_variable_wait can only be
2856 created later.
2857
2858 * threads.h: Include "coop-pthreads.h" when requested.
2859 (scm_threads_make_mutex, scm_threads_lock_mutex,
2860 scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were

2876 (scm_try_mutex, scm_broadcast_condition_variable): Newly
2877 registered procedures.
2878 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
2879 Use the latter as the procedure for "wait-condition-variable",
2880 thus offering a optional timeout parameter to Scheme.
2881 (scm_wait_condition_variable): Implement in terms of
2882 scm_timed_wait_condition_variable.
2883 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,

2885 scm_cond_wait, scm_cond_timedwait, scm_cond_signal,
2886 scm_cond_broadcast, scm_cond_destroy): Implement in terms of
2887 scm_make_mutex, etc, and deprecate.
2888 (scm_init_threads): Do not create smobs, leave this to
2889 scm_threads_init. Do not include "threads.x" file.

2900 handled by threads.{h,c}.
2901
2902 * null-threads.c (scm_null_mutex, scm_null_cond): Define here.
2903 (scm_threads_init): Create smobs here, using the appropriate
