3 | * futures.c (mark_futures): Don't need to mark data of recycled |
4 | futures. | |
5 | (scan_futures, cleanup_undead): Be smarter about marking | |
6 | futures---avoid unnecessary passes through future lists. | |
7 | ||
756414cf MD |
8 | * futures.h, futures.c: New files; Introduced recycling of |
9 | futures. For fine-grained threading this lifts performance to | |
10 | another level. We can now use parallelization in inner loops of | |
11 | Guile programs without impossible overhead. | |
12 | ||
13 | * threads.h, threads.c: Moved futures to their own file. | |
14 | ||
15 | * Makefile.am (libguile_la_SOURCES): Added futures.c. | |
16 | (DOT_X_FILES): Added futures.x. | |
17 | (DOT_DOC_FILES): Added futures.doc. | |
18 | (modinclude_HEADERS): Added futures.h. | |
19 | ||
20 | * threads.c, threads.h (scm_i_create_thread): Renamed from | |
21 | create_thread and made global. | |
22 | ||
23 | * futures.c (scm_make_future): New procedure. | |

25 | * eval.c: #include "libguile/futures.h". | |
26 | ||
27 | * init.c: #include "futures.h" | |
28 | (scm_init_guile_1): Call scm_init_futures. | |

30 | * stime.c (SCM_TIME_UNITS_PER_SECOND): Renamed from CLKTCK. | |
31 | ||
32 | * stime.h (SCM_TIME_UNITS_PER_SECOND): Definition moved here. | |
33 | ||
34 | * eval.c, eval.h (scm_trampoline_0, scm_i_call_closure_0): New | |
35 | functions. | |
36 | ||
37 | * eval.c (scm_trampoline_1): Fixed arguments test for closures. | |

40 | ||
41 | * threads.c (create_thread): Don't unwind dynwind chain of parent | |
42 | thread before creation. Just start the new thread with an empty | |
43 | dynwind chain. | |

64 | slots with instance allocation. | |
65 | ||
bbf8d523 MD |
66 | * goops.c, goops.h (scm_class_extended_generic_with_setter): New |

85 | * lang.c (scm_nil_cons, scm_nil_car, scm_nil_cdr, scm_null, |
86 | scm_m_while, scm_nil_eq): Remove definitions that were superfluous | |
87 | and already commented out. | |
88 | ||
c6a040a8 NJ |
89 | * read.h (scm_lreadparen), read.c (scm_lreadr, scm_read_token, |
90 | scm_lreadparen): Support reading vectors with Elisp syntax if | |
91 | SCM_ELISP_READ_EXTENSIONS is defined. (SCM_ELISP_READ_EXTENSIONS | |
92 | is not currently defined, and there isn't even a configure switch | |
93 | to enable it yet.) | |

95 | 2002-12-26 Marius Vollmer <mvo@zagadka.ping.de> |
96 | ||
97 | * Makefile.am (c-tokenize.o): Refer to source via $< so that vpath | |
98 | builds work. | |
99 | (EXTRA_DIST): Added version.h.in. | |

103 | This change makes it possible for one thread to do lazy sweeping | |
104 | while other threads are running. Now only the mark phase need to | |
105 | have all threads asleep. We should look further into this issue. | |
106 | Presently, I've put the locking of scm_i_sweep_mutex at | |
107 | "conservative" places due to my current lack of knowledge about | |
108 | the garbage collector. Please feel free to restrict these regions | |
109 | further to allow for maximal parallelism! | |
110 | ||
111 | * gc.c, gc.h (scm_i_sweep_mutex): New mutex. | |
112 | ||
113 | * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc, | |
114 | scm_gc_register_collectable_memory): Substitute locking of | |
115 | scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep. | |
116 | (scm_igc): Lock sweep mutex here instead of in callers; Calls to | |
117 | scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate | |
118 | the single-thread section (which now only contains the mark | |
119 | phase). | |
120 | (scm_gc): Don't lock sweeo mutex here since scm_igc locks it; | |
121 | Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly. | |
122 | ||
123 | * threads.c (gc_section_mutex): Removed. | |

0d48aca5 MD |
127 | * threads.c (create_thread): Clear parent field in root state in |
128 | order not to unnecessarily remember dead threads. | |
129 | ||
9ed24633 MD |
130 | * eval.c (call_subr2o_1, call_lsubr2_2): New functions. |
131 | (scm_trampoline_1, scm_trampoline_2): Use them. | |

133 | 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net> |
134 | ||
135 | Partial introduction of real plugin interface. | |
136 | ||
137 | * Makefile.am (modinclude_HEADERS): Added threads-plugin.h. | |
138 | (EXTRA_DIST): Added threads-plugin.c. | |
139 | ||
140 | * threads-plugin.h, threads-plugin.c: New files. | |
141 | ||
142 | * threads.h: #include "libguile/threads-plugin.h". | |
143 | ||
144 | * threads.c: #include "libguile/threads-plugin.c". | |
145 | ||
146 | * pthread-threads.c: Temporarily remove debugging functions. | |
147 | ||
148 | * threads.c, threads.h (scm_yield): Added back. | |
149 | ||
e29e0b09 MD |
150 | 2002-12-18 Mikael Djurfeldt <mdj@kvast.blakulla.net> |
151 | ||
152 | * threads.c (really_launch): Detach before unlocking | |
153 | thread_admin_mutex in order not to risk being joined. | |
154 | (scm_i_thread_put_to_sleep, scm_i_thread_wake_up): Keep | |
155 | thread_admin_mutex locked during GC. | |
156 | ||
157 | * pthread-threads.c, pthread-threads.h: Improvements to debugging | |
158 | functions. | |
159 | ||

93cd4dcd | 161 | |
6da2dfc4 MD |
162 | * pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): Added |
163 | support for debugging mutex operations. | |
164 | ||
1b92fb6b MD |
165 | * threads.c (scm_thread): Removed filed joining_threads. |
166 | (thread_print): Print thread number as well as address of thread | |
167 | structure. | |
0b6843b1 MD |
168 | (scm_join_thread): Bugfix. |
169 | (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex, | |
170 | scm_timed_wait_condition_variable, scm_signal_condition_variable, | |
171 | scm_broadcast_condition_variable): Use the low-level API. | |
172 | (scm_all_threads): Return copy of thread list (to prevent | |
173 | unintended destruction). | |
174 | (scm_threads_prehistory): Initialize heap_mutex of fake thread. | |
1b92fb6b | 175 | |
93cd4dcd MD |
176 | * pthread-threads.c, pthread-threads.h, threads.c: Fixes to |
177 | pthread "native" recursive mutex support. | |

179 | 2002-12-15 Mikael Djurfeldt <djurfeldt@nada.kth.se> |
180 | ||
28d52ebb MD |
181 | * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions. |
182 | Simply lock a thread C API recursive mutex. | |
183 | (SCM_NONREC_CRITICAL_SECTION_START, | |
184 | SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START, | |
185 | SCM_REC_CRITICAL_SECTION_END): Removed. | |
186 | ||
187 | * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with | |
188 | direct calls to scm_rec_mutex_lock / unlock around the three calls | |
189 | to scm_m_expand_body. | |
190 | ||
191 | * eval.c, eval.h (promise_free): New function. | |
192 | (scm_force): Rewritten; Now thread-safe; Removed | |
193 | SCM_DEFER/ALLOW_INTS. | |
194 | ||
195 | * pthread-threads.h: Added partially implemented plugin interface | |
196 | for recursive mutexes. These are, for now, only intended to be | |
197 | used internally within the Guile implementation. | |
198 | ||
199 | * pthread-threads.c: New file. | |
200 | ||
201 | * threads.c: Conditionally #include "pthread-threads.c". | |
202 | ||
203 | * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be | |
204 | thread-safe; | |
205 | ||
206 | * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX, | |
207 | SCM_GLOBAL_REC_MUTEX): New macros. | |
208 | ||
209 | * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section | |
210 | macros---use mutexes instead. | |
211 | ||
212 | * tags.h (SCM_IM_FUTURE): New tag. | |
213 | ||
214 | * eval.c (scm_m_future): New primitive macro. | |
215 | (SCM_CEVAL): Support futures. | |
216 | (unmemocopy): Support unmemoization of futures. | |
217 | ||
218 | * print.c (scm_isymnames): Name of future isym. | |
219 | ||
2ff4f181 MD |
220 | * version.c: Unmade some changes to my private copy that got |
221 | committed by mistake. | |
222 | ||

e200ddee MD |
225 | * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of |
226 | 2002-12-10. | |
227 | ||
392d2833 MD |
228 | * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists. |
229 | ||
230 | * gc.c (scm_gc_sweep): Call it here instead, which is a more | |
231 | logical place. | |
232 | ||
233 | * threads.c (create_thread): Remember root object until the handle | |
234 | of the new thread is on all_threads list. | |
235 | ||
236 | * root.c (scm_make_root): Moved copying of fluids until after | |
237 | creation of root handle so that the fluids are GC protected. Also | |
238 | removed the critical section. | |
239 | ||

242 | * gc-malloc.c, gc.h (scm_gc_malloc_prehistory): New function. |
243 | ||
3cdde9d6 | 244 | * gc-malloc.c (malloc_mutex): New mutex. |
960c408c | 245 | (scm_gc_malloc_prehistory): Initialize it. |
3cdde9d6 MD |
246 | (scm_realloc): Serialize call to realloc |
247 | (scm_calloc): Same for calloc. | |
248 | Thanks to Wolfgang Jaehrling! | |
249 | (Now we have to make sure all calls to malloc/realloc are made | |
250 | through scm_malloc.) | |
251 | ||
960c408c MD |
252 | * init.c (scm_init_guile_1): Call scm_gc_malloc_prehistory. |
253 | ||
c4c52ebe MD |
254 | * threads.c (really_launch): Release heap (to prevent deadlock). |
255 | (create_thread): Release heap before locking thread admin mutex. | |

257 | 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net> |
258 | ||
259 | * threads.c (scm_i_thread_invalidate_freelists): New | |
260 | function. | |
261 | ||
262 | * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists. | |
263 | ||
264 | * modules.c (scm_export): Inserted a return statement. | |

06e80f59 HWN |
266 | 2002-12-10 Han-Wen Nienhuys <hanwen@cs.uu.nl> |
267 | ||
268 | * modules.c (scm_export): new function | |
269 | ||
270 | * gc-card.c: add a note about malloc()/free() overhead. | |
271 | ||
a12611c3 MD |
272 | 2002-12-10 Mikael Djurfeldt <mdj@kvast.blakulla.net> |
273 | ||
274 | * Makefile.am (c-tokenize.$(OBJEXT)): Don't look for c-tokenize.c | |
275 | in srcdir. | |
276 | ||
c7fabadf MD |
277 | 2002-12-10 Mikael Djurfeldt <djurfeldt@nada.kth.se> |
278 | ||
279 | These changes remove scm_ints_disabled (which hasn't has any | |
280 | effect in Guile for quite some time). | |
281 | ||
282 | * async.c, error.h (scm_ints_disabled): Removed. | |
283 | ||
284 | * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1), | |
285 | root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, | |
286 | SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled. | |
287 | (old_ints): Removed. | |
288 | ||
289 | * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive | |
290 | critical section. | |
291 | (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and | |
292 | SCM_ALLOW_INTS. | |
293 | ||
9bc4701c MD |
294 | 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se> |
295 | ||
52340b65 MD |
296 | * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait): |
297 | Removed accidental #if 0 around these functions. | |
298 | ||
9bc4701c MD |
299 | These changes are the start of support for preemptive |
300 | multithreading. Marius and I have agreed that I commit this code | |
301 | into the repository although it isn't thoroughly tested and surely | |
302 | introduces many bugs. The bugs should only be exposed when using | |
303 | threads, though. Signalling and error handling for threads is | |
304 | very likely broken. Work on making the implementation cleaner and | |
305 | more efficient is needed. | |
306 | ||
307 | * __scm.h (SCM_ALLOW_INTS_ONLY): Removed. | |
308 | (SCM_NONREC_CRITICAL_SECTION_START, | |
309 | SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START, | |
310 | SCM_REC_CRITICAL_SECTION_END): New macros. | |
311 | (SCM_CRITICAL_SECTION_START/END): Defined here. | |
312 | ||
313 | * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around | |
314 | the three calls to scm_m_expand_body. | |
315 | ||
316 | * gc.h: #include "libguile/pthread-threads.h"; | |
317 | (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros. | |
318 | ||
319 | * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type | |
320 | scm_t_key; | |
321 | ||
322 | * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist | |
323 | access. | |
324 | ||
325 | * gc-freelist.c (scm_gc_init_freelist): Create freelist keys. | |
326 | ||
327 | * gc-freelist.c, threads.c (really_launch): Use | |
328 | SCM_FREELIST_CREATE. | |
329 | ||
330 | * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory): | |
331 | ||
332 | * gc.c (scm_i_expensive_validation_check, scm_gc, | |
333 | scm_gc_for_newcell): Put threads to sleep before doing GC-related | |
334 | heap administration so that those pieces of code are executed | |
335 | single-threaded. We might consider rewriting these code sections | |
336 | in terms of a "call_gc_code_singly_threaded" construct instead of | |
337 | calling the pair of scm_i_thread_put_to_sleep () and | |
338 | scm_i_thread_wake_up (). Also, we would want to have as many of | |
339 | these sections eleminated. | |
340 | ||
341 | * init.c (scm_init_guile_1): Call scm_threads_prehistory. | |
342 | ||
343 | * inline.h: #include "libguile/threads.h" | |
344 | ||
345 | * pthread-threads.h: Macros now conform more closely to the | |
346 | pthreads interface. Some of them now take a second argument. | |
347 | ||
348 | * threads.c, threads.h: Many changes. | |
349 | ||
350 | 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se> | |
351 | ||
352 | * Makefile.am (version.h): Changed $^ --> $< in rule for | |
353 | version.h. | |
354 | ||
b2cbe8d8 RB |
355 | 2002-12-08 Rob Browning <rlb@defaultvalue.org> |
356 | ||
357 | * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now. | |
358 | (SCM_MINOR_VERSION): use @--@ substitution now. | |
359 | (SCM_MICRO_VERSION): use @--@ substitution now. | |
360 | (scm_effective_version): new function prototype. | |
361 | ||
362 | * version.c (scm_effective_version): new function, also add | |
363 | effective-version. | |
364 | ||
365 | * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION. | |
366 | (libpath.h): use GUILE_EFFECTIVE_VERSION to compute | |
367 | SCM_LIBRARY_DIR. | |
368 | (version.h): generate this here rather than configure.in. This | |
369 | approach tracks source edits better (i.e. more immediately). | |
370 | Might be worth considering for other .in files too. | |

372 | 2002-12-02 Marius Vollmer <mvo@zagadka.ping.de> |
373 | ||
374 | Reorganized thread package selection. A thread package now only | |
375 | implements a small set of pthread like functions and Guile | |
376 | implements the rest on top of that. Guile's implementation is | |
377 | what the "coop-pthreads" package has been previously. Support for | |
378 | "coop" threads has been removed until I get time to add it again. | |
379 | ||
380 | * Makefile.am (libguile_la_SOURCES): Removed iselect.c. | |
381 | (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c, | |
382 | null-threads.c, coop-pthreads.c. | |
383 | (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added | |
384 | pthread-threads.h. | |
385 | ||
386 | * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h. | |
387 | ||
388 | * threads.h: Do not include "libguile/coop-defs.h". Include | |
389 | "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed | |
390 | (previously deprecated) C level thread API prototypes. They are | |
391 | now in the thread package specific headers, "null-threads.h" and | |
392 | "pthread-threads.h". | |
393 | (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR): | |
394 | New. | |

417 | The following change makes it possible to move procedure | |
418 | application dispatch outside inner loops. The motivation was | |
419 | clean implementation of efficient replacements of R5RS primitives | |
420 | in SRFI-1. | |
421 | ||
422 | The semantics is clear: scm_trampoline_N returns an optimized | |
423 | version of scm_call_N (or NULL if the procedure isn't applicable | |
424 | on N args). | |
425 | ||
426 | Applying the optimization to map and for-each increases efficiency | |
427 | noticeably. For example, (map abs ls) is 8 times faster than | |
428 | before. | |
429 | ||
430 | * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types. | |
431 | ||
432 | * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions. | |
433 | ||
434 | * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions; | |
435 | (map, for-each): Handle also application on two args as a special | |
436 | case; Use trampolines. | |
437 | ||
438 | Other changes: | |
439 | ||
440 | * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o; | |
441 | (subr2oless): Removed. | |
442 | (scm_restricted_vector_sort_x): Use scm_return_first to keep the | |
443 | vector GC protected. | |
444 | ||
445 | * eval.c (check_map_args): Use scm_out_of_range_pos instead of | |
446 | scm_out_of_range. | |

468 | module_variable, scm_module_lookup_closure, | |
469 | scm_module_transformer, scm_sym2var, scm_module_reverse_lookup, | |
470 | scm_system_module_env_p): Don't compare SCM values with C | |
471 | operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP | |
472 | over SCM_NFALSEP. | |

481 | 2002-11-14 Mikael Djurfeldt <mdj@linnaeus> |
482 | ||
483 | * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be | |
484 | part of the API, otherwise it's difficult to write Guile | |
485 | extensions using non-blocking I/O => moved #include | |
486 | "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h. | |
487 | ||
488 | * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex --> | |
489 | s_unlock_mutex. | |

494 | are defined in configure.in. | |
495 | ||
496 | * threads.c: Removed SCM_API from function definitions. SCM_API | |
497 | is only for declarations. | |

544 | start testing it now. | |
545 | ||
546 | * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly | |
547 | defined when HAVE_RESTARTABLE_SYSCALLS is not defined. | |

554 | scm_delq_spine_x, really_install_handler, install_handler): New | |

558 | hasn't exited yet. | |

561 | signal_asyncs. Don't set cdr of a non-signal async to #f. | |

619 | scm_cond_broadcast, scm_cond_destroy): Implement in terms of | |
620 | scm_make_mutex, etc, and deprecate. | |
