MV		 12003-05-04 Marius Vollmer <mvo@zagadka.de>
2
3 * throw.c (scm_ithrow): Remove "asm volatile" hack. It used to

MD		 282003-04-28 Mikael Djurfeldt <djurfeldt@nada.kth.se>
29
30 * eval.c (scm_m_atdispatch): Removed until actually needed. (This
31 macro was introduced in anticipation of GOOPS method compilation
32 code.)
33
34 * goops.c: Removed binding of @dispatch.
35

DH		 362003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
37
38 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
39 instructions that bind the macros on the scheme level back to
40 goops.c in order to make sure again that the bindings go into the
41 (oop goops) module and are not visible from the outside.
42
9fbee57e
DH		 432003-04-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
44
45 * eval.c: Non functional change: Separated R5RS and non-R5RS
46 macros into different sections of the file and ordered the
47 memoizers alphabetically.

54
55 * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
56 Partially reverted patch from 2003-04-23 in oder to find a better

DH		 592003-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
60
61 * eval.c, eval.h, goops.c, goops.h (scm_m_atslot_ref,
62 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
63 definitions of the special goops memoizers from goops.[ch] to
64 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used
65 throughout guile.
66

DH		 862003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
87
88 This set of patches contains no functional changes, only debatable
89 minor stylistic ones. Still, in order to prepare a patch between
90 my local copy and the CVS version, I decided to submit the changes
91 below. Then, the patch will hopefully only contain relevant
92 modifications :-)
93
94 * eval.c (iqq): Added const specifier.
95
96 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
97 Use NULL instead of 0 to indicate that a pointer is returned.
98 Removed some misleading 'fall through' comments.
99
100 * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
101 Split up long expressions into smaller ones to be more debugging
102 friendly.
103

105
106 * eval.h (SCM_ENTER_FRAME_HDLR, SCM_APPLY_FRAME_HDLR,
107 SCM_EXIT_FRAME_HDLR): Use SCM_PACK to convert data to a SCM value
108 rather than casting to SCM.
109
c178c3a6
DH		 1102003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
111
112 * sort.c, pairs.h: Removed unnecessary includes.
113
d339981a
DH		 1142003-04-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
115
116 * sort.c: Replaced hand-made trampline code by the new official
117 mechanism from eval.c. This fixes a segfault in the new test file
118 sort.test.
119
120 (quicksort, compare_function, scm_restricted_vector_sort_x,
121 scm_sorted_p, scm_merge, scm_merge_list_x, scm_merge_x,
122 scm_merge_list_step, scm_sort_x, scm_sort, scm_merge_vector_x,
123 scm_merge_vector_step, scm_stable_sort_x, scm_stable_sort,
124 scm_sort_list_x, scm_sort_list): Use trampoline mechanism from
125 eval.c.
126
127 (subr2less, lsubrless, closureless, applyless, scm_cmp_function,
128 cmp_fun_t): Removed.
129
130 (compare_function): Added.
131
132 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
133 arithmetics with index arithmetics. Changed quicksort to work on
134 an array of SCM values instead of an array of characters. Avoid
135 bytewise copying of SCM elements. Avoid allocating memory on the
136 stack with alloca. Fixed some comments.
137
821f18a4
DH		 1382003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
139
140 * eval.c (EXTEND_ENV): Eliminated.

142 (unmemocopy, SCM_CEVAL, SCM_APPLY): Use SCM_EXTEND_ENV instead of
143 EXTEND_ENV.

155 scm_gc_marked_p, scm_gc_get_card, scm_gc_get_bvec): Fixed
156 functions such that they check if the object is a non-immediate.
157 Further, renamed identifiers to use the scm_dbg_ prefix and made
158 their inclusion into the lib dependent of the
159 SCM_DEBUG_DEBUGGER_SUPPORT compile time option.
160
fce0b22d
DH		 1612003-04-21 Dirk Herrmann <D.Herrmann@tu-bs.de>

195 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
196 and definition of the memoizer for the generalized set! macro from
197 evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
198 define the macro object.
199
200 * eval.c, eval.h (s_set_x, scm_s_set_x, scm_m_set_x,
201 scm_m_generalized_set_x): Since now scm_s_set_x is only used in
202 eval.c, it is made static and renamed to s_set_x.
203
204 * evalext.c (scm_defined_p, scm_m_undefine): Prefer !SCM_<foo>
205 over SCM_N<foo>.

212
213 * eval.c, eval.h (scm_f_apply, scm_init_eval): Made scm_f_apply
214 static in eval.c, renamed it to f_apply and registered the object

285 test. Instead use
286 #if defined (sparc) || defined (__sparc__) || defined (__sparc)
287 as gc_os_dep.c suggests is appropriate.
288
289 * goops.c (prep_hashsets): make static to match prototype.
290 (scm_sym_args): SCM_SYMBOL -> SCM_GLOBAL_SYMBOL. Thanks to Albert
291 Chin.

878 * numbers.c (scm_abs): Use SCM_PRIMITIVE_GENERIC. (This is only a
879 testing example. All uses of SCM_GPROC should be converted.)

881 * procprop.c (scm_stand_in_scm_proc): Use scm_assq instead of
882 scm_assoc.

MD		 895 This fixes a serious GC bug, introduced during the latest
896 reorganization of the GC, which disabled freeing of structs and
897 GOOPS objects:
898
899 * struct.c (scm_struct_prehistory): Init scm_i_structs_to_free to
900 SCM_EOL.

911 (since hash tables now adapt their size).
912
913 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
914 (current number of prehistory bindings; hashtable code will select
915 a prime which is greater than this value).

930 The following changes introduce the use of resizable hash tables
931 throughout Guile. It also renames the old *-hash-table* functions
932 to *-alist-vector* and places them, together with the rest of the
933 weak vector support, in the module (ice-9 weak-vector). We should
934 probably introduce a new, better, API for weak references, for
935 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
936 look like and are used like ordinary pairs.)
937

957 scm_make_doubly_weak_hash_table): Moved here from weaks.c.
958

973 SCM_WVECTF_NOSCAN, SCM_WVECT_WEAK_KEY_P, SCM_WVECT_WEAK_VALUE_P,
974 SCM_WVECT_NOSCAN_P): New macros.

977 and SCM_WVECT_WEAK_VALUE_P.

985 let the user explicitly protect the tables (or not) according what
986 is suitable for the application.)

1023 futures---avoid unnecessary passes through future lists.
1024
756414cf
MD		 1025 * futures.h, futures.c: New files; Introduced recycling of

1120 This change makes it possible for one thread to do lazy sweeping
1121 while other threads are running. Now only the mark phase need to
1122 have all threads asleep. We should look further into this issue.
1123 Presently, I've put the locking of scm_i_sweep_mutex at
1124 "conservative" places due to my current lack of knowledge about
1125 the garbage collector. Please feel free to restrict these regions
1126 further to allow for maximal parallelism!
1127
1128 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
1129
1130 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
1131 scm_gc_register_collectable_memory): Substitute locking of
1132 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
1133 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
1134 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
1135 the single-thread section (which now only contains the mark
1136 phase).
1137 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
1138 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
1139
1140 * threads.c (gc_section_mutex): Removed.

1203
1204 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with

1314 Removed accidental #if 0 around these functions.

MD		 1316 These changes are the start of support for preemptive
1317 multithreading. Marius and I have agreed that I commit this code
1318 into the repository although it isn't thoroughly tested and surely
1319 introduces many bugs. The bugs should only be exposed when using
1320 threads, though. Signalling and error handling for threads is
1321 very likely broken. Work on making the implementation cleaner and
1322 more efficient is needed.
1323
1324 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
1325 (SCM_NONREC_CRITICAL_SECTION_START,
1326 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
1327 SCM_REC_CRITICAL_SECTION_END): New macros.
1328 (SCM_CRITICAL_SECTION_START/END): Defined here.
1329
1330 * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
1331 the three calls to scm_m_expand_body.

1337 scm_t_key;
1338
1339 * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
1340 access.
1341
1342 * gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
1343
1344 * gc-freelist.c, threads.c (really_launch): Use
1345 SCM_FREELIST_CREATE.
1346
1347 * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
1348
1349 * gc.c (scm_i_expensive_validation_check, scm_gc,
1350 scm_gc_for_newcell): Put threads to sleep before doing GC-related
1351 heap administration so that those pieces of code are executed
1352 single-threaded. We might consider rewriting these code sections
1353 in terms of a "call_gc_code_singly_threaded" construct instead of
1354 calling the pair of scm_i_thread_put_to_sleep () and
1355 scm_i_thread_wake_up (). Also, we would want to have as many of
1356 these sections eleminated.
1357
1358 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
1359
1360 * inline.h: #include "libguile/threads.h"

1362 * pthread-threads.h: Macros now conform more closely to the
1363 pthreads interface. Some of them now take a second argument.
1364

1383 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
1384 SCM_LIBRARY_DIR.
1385 (version.h): generate this here rather than configure.in. This
1386 approach tracks source edits better (i.e. more immediately).
1387 Might be worth considering for other .in files too.

1390
1391 Reorganized thread package selection. A thread package now only
1392 implements a small set of pthread like functions and Guile
1393 implements the rest on top of that. Guile's implementation is
1394 what the "coop-pthreads" package has been previously. Support for
1395 "coop" threads has been removed until I get time to add it again.
1396
1397 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
1398 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
1399 null-threads.c, coop-pthreads.c.
1400 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
1401 pthread-threads.h.
1402
1403 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
1404
1405 * threads.h: Do not include "libguile/coop-defs.h". Include
1406 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
1407 (previously deprecated) C level thread API prototypes. They are
1408 now in the thread package specific headers, "null-threads.h" and
1409 "pthread-threads.h".
1410 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
1411 New.
1412 (scm_threads_init): Removed.
1413 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
1414 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
1415 SCM_I_THREAD_SWITCH_COUNT): Define here.
1416 (scm_single_thread_p): Removed.
1417 (scm_call_with_new_thread): Take two args directly instead of list
1418 of two args.
1419 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
1420 SCM_SET_THREAD_LOCAL_DATA): Define here.
1421
1422 * threads.c: Merged with "coop-pthreads.c".
1423
1424 * null-threads.h: Implement pthread-like API as a set of macros.
1425
1426 * pthread-threads.h: New, implement pthread-like API by deferring
1427 to pthread itself.
1428
1429 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
1430 has been lost in the reorganization.

1434 The following change makes it possible to move procedure
1435 application dispatch outside inner loops. The motivation was
1436 clean implementation of efficient replacements of R5RS primitives
1437 in SRFI-1.
1438
1439 The semantics is clear: scm_trampoline_N returns an optimized
1440 version of scm_call_N (or NULL if the procedure isn't applicable
1441 on N args).
1442
1443 Applying the optimization to map and for-each increases efficiency
1444 noticeably. For example, (map abs ls) is 8 times faster than
1445 before.
1446
1447 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
1448
1449 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
1450
1451 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
1452 (map, for-each): Handle also application on two args as a special
1453 case; Use trampolines.
1454
1455 Other changes:
1456
1457 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
1458 (subr2oless): Removed.
1459 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
1460 vector GC protected.
1461
1462 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
1463 scm_out_of_range.

1487 scm_system_module_env_p): Don't compare SCM values with C

1489 over SCM_NFALSEP.

1500 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
1501 part of the API, otherwise it's difficult to write Guile
1502 extensions using non-blocking I/O => moved #include
1503 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
1504

1561 start testing it now.
1562

1570 * scmsigs.c (signal_cell_handlers, install_handler_data,
1571 scm_delq_spine_x, really_install_handler, install_handler): New
1572 scheme for triggering signal handlers, to simplify take_signal.
1573 (take_signal): Simplified, to avoid race conditions.
1574 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
1575 hasn't exited yet.
1576
1577 * async.c (scm_async_click): Reset pending_asyncs, handle
1578 signal_asyncs. Don't set cdr of a non-signal async to #f.
1579 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
1580 always. Set pending_asyncs.
1581 (scm_system_async_mark_for_thread): Check that thread has not
1582 exited.
1583 (scm_unmask_signals, decrease_block): Call scm_async_click after
1584 block_asyncs becomes zero.
1585
1586 * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of
1587 active_asyncs.

1601 USE_COPT_THREADS to not protect the slot initializers.
1602
1603 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
1604 because threads need to be initialized before the stack, but
1605 gsubrs such as scm_timed_condition_variable_wait can only be
1606 created later.
1607
1608 * threads.h: Include "coop-pthreads.h" when requested.
1609 (scm_threads_make_mutex, scm_threads_lock_mutex,
1610 scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were

1626 (scm_try_mutex, scm_broadcast_condition_variable): Newly
1627 registered procedures.
1628 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
1629 Use the latter as the procedure for "wait-condition-variable",
1630 thus offering a optional timeout parameter to Scheme.
1631 (scm_wait_condition_variable): Implement in terms of
1632 scm_timed_wait_condition_variable.
1633 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,
1634 scm_mutex_unlock, scm_mutex_destroy, scm_cond_init,
1635 scm_cond_wait, scm_cond_timedwait, scm_cond_signal,
1636 scm_cond_broadcast, scm_cond_destroy): Implement in terms of
1637 scm_make_mutex, etc, and deprecate.
1638 (scm_init_threads): Do not create smobs, leave this to
1639 scm_threads_init. Do not include "threads.x" file.

1648 scm_cond_wait, scm_cond_signal, scm_cond_broadcast,
1649 scm_cond_destory): Do not define, they are now deprecated and
1650 handled by threads.{h,c}.
1651
1652 * null-threads.c (scm_null_mutex, scm_null_cond): Define here.
1653 (scm_threads_init): Create smobs here, using the appropriate
1654 sizes.
