3 | * gc-malloc.c, gc.h, init.c: Reverted gc-malloc change of |
4 | 2002-12-10. | |
5 | ||
392d2833 MD |
6 | * gc.c (scm_igc): Don't call scm_i_thread_invalidate_freelists. |
7 | ||
8 | * gc.c (scm_gc_sweep): Call it here instead, which is a more | |
9 | logical place. | |
10 | ||
11 | * threads.c (create_thread): Remember root object until the handle | |
12 | of the new thread is on all_threads list. | |
13 | ||
14 | * root.c (scm_make_root): Moved copying of fluids until after | |
15 | creation of root handle so that the fluids are GC protected. Also | |
16 | removed the critical section. | |

24 | (scm_realloc): Serialize call to realloc |
25 | (scm_calloc): Same for calloc. | |
26 | Thanks to Wolfgang Jaehrling! | |
27 | (Now we have to make sure all calls to malloc/realloc are made | |
28 | through scm_malloc.) | |
29 | ||
960c408c MD |

31 | ||
c4c52ebe MD |

38 | function. | |
39 | ||
40 | * gc.c (scm_igc): Call scm_i_thread_invalidate_freelists. | |
41 | ||

57 | These changes remove scm_ints_disabled (which hasn't has any | |
58 | effect in Guile for quite some time). | |
59 | ||
60 | * async.c, error.h (scm_ints_disabled): Removed. | |
61 | ||
62 | * gc.c (scm_gc_for_newcell), init.c (scm_init_guile_1), | |
63 | root.c (scm_internal_cwdr), gdbint.c (SCM_BEGIN_FOREIGN_BLOCK, | |
64 | SCM_END_FOREIGN_BLOCK): Don't touch scm_ints_disabled. | |
65 | (old_ints): Removed. | |
66 | ||
67 | * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): Define as a recursive | |
68 | critical section. | |
69 | (SCM_REDEFER_INTS, SCM_ALLOW_INTS): Define as SCM_DEFER_INTS and | |
70 | SCM_ALLOW_INTS. | |

74 | * threads.c (scm_mutex_lock, scm_cond_wait, scm_cond_timedwait): |
75 | Removed accidental #if 0 around these functions. | |
76 | ||
9bc4701c MD |
77 | These changes are the start of support for preemptive |
78 | multithreading. Marius and I have agreed that I commit this code | |
79 | into the repository although it isn't thoroughly tested and surely | |
80 | introduces many bugs. The bugs should only be exposed when using | |
81 | threads, though. Signalling and error handling for threads is | |
82 | very likely broken. Work on making the implementation cleaner and | |
83 | more efficient is needed. | |
84 | ||
85 | * __scm.h (SCM_ALLOW_INTS_ONLY): Removed. | |
86 | (SCM_NONREC_CRITICAL_SECTION_START, | |
87 | SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START, | |
88 | SCM_REC_CRITICAL_SECTION_END): New macros. | |
89 | (SCM_CRITICAL_SECTION_START/END): Defined here. | |
90 | ||
91 | * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around | |
92 | the three calls to scm_m_expand_body. | |
93 | ||
94 | * gc.h: #include "libguile/pthread-threads.h"; | |
95 | (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros. | |
96 | ||
97 | * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type | |
98 | scm_t_key; | |
99 | ||
100 | * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist | |
101 | access. | |
102 | ||
103 | * gc-freelist.c (scm_gc_init_freelist): Create freelist keys. | |
104 | ||
105 | * gc-freelist.c, threads.c (really_launch): Use | |
106 | SCM_FREELIST_CREATE. | |
107 | ||
108 | * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory): | |
109 | ||
110 | * gc.c (scm_i_expensive_validation_check, scm_gc, | |
111 | scm_gc_for_newcell): Put threads to sleep before doing GC-related | |
112 | heap administration so that those pieces of code are executed | |
113 | single-threaded. We might consider rewriting these code sections | |
114 | in terms of a "call_gc_code_singly_threaded" construct instead of | |
115 | calling the pair of scm_i_thread_put_to_sleep () and | |
116 | scm_i_thread_wake_up (). Also, we would want to have as many of | |
117 | these sections eleminated. | |
118 | ||
119 | * init.c (scm_init_guile_1): Call scm_threads_prehistory. | |
120 | ||
121 | * inline.h: #include "libguile/threads.h" | |
122 | ||
123 | * pthread-threads.h: Macros now conform more closely to the | |
124 | pthreads interface. Some of them now take a second argument. | |
125 | ||
126 | * threads.c, threads.h: Many changes. | |
127 | ||
128 | 2002-12-09 Mikael Djurfeldt <djurfeldt@nada.kth.se> | |
129 | ||
130 | * Makefile.am (version.h): Changed $^ --> $< in rule for | |
131 | version.h. | |
132 | ||
b2cbe8d8 RB |
133 | 2002-12-08 Rob Browning <rlb@defaultvalue.org> |
134 | ||
135 | * version.h.in (SCM_MICRO_VERSION): use @--@ substitution now. | |
136 | (SCM_MINOR_VERSION): use @--@ substitution now. | |
137 | (SCM_MICRO_VERSION): use @--@ substitution now. | |
138 | (scm_effective_version): new function prototype. | |
139 | ||
140 | * version.c (scm_effective_version): new function, also add | |
141 | effective-version. | |
142 | ||
143 | * Makefile.am (schemelibdir): VERSION -> GUILE_EFFECTIVE_VERSION. | |
144 | (libpath.h): use GUILE_EFFECTIVE_VERSION to compute | |
145 | SCM_LIBRARY_DIR. | |
146 | (version.h): generate this here rather than configure.in. This | |
147 | approach tracks source edits better (i.e. more immediately). | |
148 | Might be worth considering for other .in files too. | |

151 | ||
152 | Reorganized thread package selection. A thread package now only | |
153 | implements a small set of pthread like functions and Guile | |
154 | implements the rest on top of that. Guile's implementation is | |
155 | what the "coop-pthreads" package has been previously. Support for | |
156 | "coop" threads has been removed until I get time to add it again. | |
157 | ||
158 | * Makefile.am (libguile_la_SOURCES): Removed iselect.c. | |
159 | (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c, | |
160 | null-threads.c, coop-pthreads.c. | |
161 | (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added | |
162 | pthread-threads.h. | |
163 | ||
164 | * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h. | |
165 | ||
166 | * threads.h: Do not include "libguile/coop-defs.h". Include | |
167 | "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed | |
168 | (previously deprecated) C level thread API prototypes. They are | |
169 | now in the thread package specific headers, "null-threads.h" and | |
170 | "pthread-threads.h". | |
171 | (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR): | |
172 | New. | |
173 | (scm_threads_init): Removed. | |
174 | (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END, | |
175 | SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter, | |
176 | SCM_I_THREAD_SWITCH_COUNT): Define here. | |
177 | (scm_single_thread_p): Removed. | |
178 | (scm_call_with_new_thread): Take two args directly instead of list | |
179 | of two args. | |
180 | (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA, | |
181 | SCM_SET_THREAD_LOCAL_DATA): Define here. | |
182 | ||
183 | * threads.c: Merged with "coop-pthreads.c". | |
184 | ||
185 | * null-threads.h: Implement pthread-like API as a set of macros. | |
186 | ||
187 | * pthread-threads.h: New, implement pthread-like API by deferring | |
188 | to pthread itself. | |
189 | ||
190 | * init.c (scm_init_guile_1): Do not call scm_init_iselect, which | |
191 | has been lost in the reorganization. | |
192 | ||

194 | ||
195 | The following change makes it possible to move procedure | |
196 | application dispatch outside inner loops. The motivation was | |
197 | clean implementation of efficient replacements of R5RS primitives | |
198 | in SRFI-1. | |
199 | ||
200 | The semantics is clear: scm_trampoline_N returns an optimized | |
201 | version of scm_call_N (or NULL if the procedure isn't applicable | |
202 | on N args). | |
203 | ||
204 | Applying the optimization to map and for-each increases efficiency | |
205 | noticeably. For example, (map abs ls) is 8 times faster than | |
206 | before. | |
207 | ||
208 | * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types. | |
209 | ||
210 | * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions. | |
211 | ||
212 | * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions; | |
213 | (map, for-each): Handle also application on two args as a special | |
214 | case; Use trampolines. | |
215 | ||
216 | Other changes: | |
217 | ||
218 | * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o; | |
219 | (subr2oless): Removed. | |
220 | (scm_restricted_vector_sort_x): Use scm_return_first to keep the | |
221 | vector GC protected. | |
222 | ||
223 | * eval.c (check_map_args): Use scm_out_of_range_pos instead of | |
224 | scm_out_of_range. | |
225 | ||

226 | 2002-11-24 Dirk Herrmann <D.Herrmann@tu-bs.de> |
227 | ||
228 | * evalext.[ch] (scm_m_undefine, undefine): Deprecated. | |
229 | ||
4ba5f279 MD |
230 | 2002-11-17 Mikael Djurfeldt <mdj@linnaeus> |
231 | ||
232 | * debug.c (scm_make_iloc): Added missing "return". | |
233 | ||
56ae231f MV |
234 | 2002-11-17 Marius Vollmer <mvo@zagadka.ping.de> |
235 | ||
236 | * strports.c (scm_eval_string_in_module): Validate second arg to | |
237 | be a module. Thanks to Arno Peters! | |
238 | ||
80b28865 DH |
239 | 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de> |
240 | ||
241 | * .cvsignore: remove goops.c | |
242 | ||
c88b1456 DH |
243 | 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de> |
244 | ||
245 | * modules.c (scm_env_top_level, scm_lookup_closure_module, | |
246 | module_variable, scm_module_lookup_closure, | |
247 | scm_module_transformer, scm_sym2var, scm_module_reverse_lookup, | |
248 | scm_system_module_env_p): Don't compare SCM values with C | |
249 | operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP | |
250 | over SCM_NFALSEP. | |
251 | ||
a8a19efc DH |
252 | 2002-11-16 Dirk Herrmann <D.Herrmann@tu-bs.de> |
253 | ||
254 | * eval.h (SCM_MAKE_ILOC): New macro. | |
255 | ||
256 | * debug.c (scm_make_iloc): Use SCM_MAKE_ILOC instead of computing | |
257 | the iloc bitpattern here. | |
258 | ||
76734914 MD |
259 | 2002-11-14 Mikael Djurfeldt <mdj@linnaeus> |
260 | ||
261 | * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be | |
262 | part of the API, otherwise it's difficult to write Guile | |
263 | extensions using non-blocking I/O => moved #include | |
264 | "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h. | |
265 | ||
266 | * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex --> | |
267 | s_unlock_mutex. | |
268 | ||
8b5b4a75 MV |
269 | 2002-11-10 Marius Vollmer <mvo@zagadka.ping.de> |
270 | ||
271 | * __scm.h (USE_THREADS, GUILE_ISELECT): Do not define here. They | |
272 | are defined in configure.in. | |
273 | ||
274 | * threads.c: Removed SCM_API from function definitions. SCM_API | |
275 | is only for declarations. | |
276 | ||
e5a83084 MD |
277 | 2002-11-07 Mikael Djurfeldt <mdj@linnaeus> |
278 | ||
9be8bb45 MD |
279 | * coop-pthreads.h: Added support for thread specific data to the |
280 | generic C API for the coop-pthreads case. | |
281 | ||
e5a83084 MD |
282 | * threads.c, threads.h (scm_cond_init): Undo unintentional API |
283 | change. | |
6c214b62 | 284 | (scm_cond_broadcast): Added missing function. |

7edf178e MV |
286 | 2002-11-04 Marius Vollmer <marius.vollmer@uni-dortmund.de> |
287 | ||
288 | * coop.c (coop_next_runnable_thread): Removed, wich should have | |
289 | happened when GUILE_ISELECT was hard-wired. | |
290 | ||
7f5b1b77 MV |
291 | 2002-11-03 Marius Vollmer <mvo@zagadka.ping.de> |
292 | ||
7caa1b07 MV |
293 | * Makefile.am (libguile_la_SOURCES): Added threads.c |
294 | (DOT_DOC_FILES): Added threads.doc. | |
295 | (DOT_X_FILES): Added threads.x. | |
296 | (EXTRA_libguile_la_SOURCES): Removed threads.c. | |
297 | (noinst_HEADERS): Added coop-pthreads.c. | |
298 | (modinclude_HEADERS): Added coop-pthreads.h. | |
299 | ||
300 | * __scm.h (USE_THREADS, GUILE_ISELECT): Define when | |
301 | SCM_DEBUG_DEPRECATED. Removed their use thru-out Guile. | |
302 | ||
bb11cbf4 MV |
303 | * iselect.c: Include "_scm.h" before testing HAVE_UNISTD_H. |
304 | Thanks to Bill Schottstaedt! | |
305 | ||
1d4cbbed MV |
306 | * numbers.c (scm_integer_expt): Make 0^z == 0 for z != 0. |
307 | ||
7f5b1b77 MV |
308 | * _scm.h (HAVE_RESTARTABLE_SYSCALLS): Do define even when |
309 | SCM_COPT_THREADS is defined. | |
310 | (SCM_SYSCALL): Use EINTR-expection version when SCM_COPT_THREADS | |
311 | is defined. | |
312 | ||
313 | * coop-pthreads.c: Some harmless renamings of internal stuff. | |
314 | (create_thread): New, generalized version of | |
315 | scm_call_with_new_thread. | |
316 | (scm_call_with_new_thread): Use it. | |
317 | (scm_spawn_thread): New, use create_thread. | |
318 | ||
d52f53b1 MV |
319 | 2002-11-02 Marius Vollmer <mvo@zagadka.ping.de> |
320 | ||
321 | * coop-pthreads.c, coop-pthreads.h: Redone completely, you might | |
322 | start testing it now. | |
323 | ||
324 | * _scm.h: Include <errno.h< so that SCM_SYSCALL is correctly | |
325 | defined when HAVE_RESTARTABLE_SYSCALLS is not defined. | |
326 | (HAVE_RESTARTABLE_SYSCALLS): Do not define when USE_COPT_THREADS | |
327 | is defined. | |
328 | ||
30f920c3 MV |
329 | 2002-10-27 Marius Vollmer <mvo@zagadka.ping.de> |
330 | ||
331 | * scmsigs.c (signal_cell_handlers, install_handler_data, | |
332 | scm_delq_spine_x, really_install_handler, install_handler): New | |
333 | scheme for triggering signal handlers, to simplify take_signal. | |
334 | (take_signal): Simplified, to avoid race conditions. | |
335 | (scm_sigaction_for_thread): Use new Scheme. Validate that thread | |
336 | hasn't exited yet. | |
337 | ||
338 | * async.c (scm_async_click): Reset pending_asyncs, handle | |
339 | signal_asyncs. Don't set cdr of a non-signal async to #f. | |
340 | (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue | |
341 | always. Set pending_asyncs. | |
342 | (scm_system_async_mark_for_thread): Check that thread has not | |
343 | exited. | |
344 | (scm_unmask_signals, decrease_block): Call scm_async_click after | |
345 | block_asyncs becomes zero. | |
346 | ||
347 | * __scm.h (SCM_ASYNC_CLICK): Check pending_asyncs instead of | |
348 | active_asyncs. | |
349 | ||
350 | * root.h (scm_root_state): Added pending_asyncs and signal_asyncs | |
351 | fields. | |
352 | * root.c (root_mark): Mark them. | |
353 | (make_root): Initialize them. | |
354 | ||
355 | * iselect.c, iselect.h: Replaced GUILE_ISELECT with | |
356 | USE_COOP_THREADS. | |
357 | (scm_internal_select): Define one version for USE_COOP_THREADS and | |
358 | one for USE_NULL_THREADS. | |
359 | (scm_init_iselect): Likewise. | |
360 | ||
361 | * inline.h (scm_cell, scm_double_cell): Also allow | |
362 | USE_COPT_THREADS to not protect the slot initializers. | |
363 | ||
364 | * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is | |
365 | because threads need to be initialized before the stack, but | |
366 | gsubrs such as scm_timed_condition_variable_wait can only be | |
367 | created later. | |
368 | ||
369 | * threads.h: Include "coop-pthreads.h" when requested. | |
370 | (scm_threads_make_mutex, scm_threads_lock_mutex, | |
371 | scm_threads_unlock_mutex, scm_threads_monitor): Removed, they were | |
372 | not implemented anyway. | |
373 | (scm_init_thread_procs, scm_try_mutex, | |
374 | scm_timed_condition_variable_wait, | |
375 | scm_broadcast_condition_variable, scm_c_thread_exited_p, | |
376 | scm_thread_exited_p): New prototypes. | |
377 | (struct timespec): Define if not already defined. | |
378 | (scm_t_mutex, scm_mutex_init, scm_mutex_lock, scm_mutex_trylock, | |
379 | scm_mutex_unlock, scm_mutex_destroy, scm_t_cond, scm_cond_init, | |
380 | scm_cond_wait, scm_cond_timedwait, scm_cond_signal, | |
381 | scm_cond_broadcast, scm_cond_destroy): Declarations moved here and | |
382 | deprecated. | |
383 | ||
384 | * threads.c: Include <errno.h>. Include "coop-pthreads.c" when | |
385 | requested. | |
386 | (scm_thread_exited_p): New. | |
387 | (scm_try_mutex, scm_broadcast_condition_variable): Newly | |
388 | registered procedures. | |
389 | (scm_wait_condition_variable, scm_timed_wait_condition_variable): | |
390 | Use the latter as the procedure for "wait-condition-variable", | |
391 | thus offering a optional timeout parameter to Scheme. | |
392 | (scm_wait_condition_variable): Implement in terms of | |
393 | scm_timed_wait_condition_variable. | |
