2
3 * tags.h (SCM_IM_ELSE, SCM_IM_ARROW): New memoizer codes.
4
5 * print.c (scm_isymnames): Add names for the new memoizer codes.
6
7 * eval.c (s_missing_clauses, s_bad_case_clause,
8 s_extra_case_clause, s_bad_case_labels, s_duplicate_case_label,
9 literal_p): New static identifiers.
10
11 (scm_m_case): Use ASSERT_SYNTAX to signal syntax errors. Be more
12 specific about the kind of error that was detected. Check for
13 duplicate case labels. Handle bound 'else. Avoid unnecessary
14 consing when creating the memoized code.
15
16 (scm_m_case, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
17 the syntactic keyword 'else.

28
29 * numbers.c (scm_inexact_to_exact): Don't depend on what double->long
30 cast gives for values bigger than a long, or for nan or inf.

ff6ea7b9 44 * strports.c (scm_call_with_output_string): scm_get_output_string
591924eb
KR		 45 rather than scm_strport_to_string, so as to guard against the port
46 having been closed by the called procedure. Reported by Nic Ferrier.

DH		 552003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
56
57 This set of patches introduces a new tc7 code scm_tc7_number for
58 numbers. Bignums, reals and complex numbers are turned from smobs
59 into subtypes of scm_tc7_number.
60
61 * tags.h (scm_tc7_number): New.
62
63 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), evalext.c
64 (scm_self_evaluating_p), gc-card.c (scm_i_sweep_card), gc-mark.c
65 (scm_gc_mark_dependencies), goops.c (create_smob_classes), hash.c
66 (scm_hasher), numbers.c, numbers.h (SCM_NUMP), objects.c
67 (scm_class_of), print.c (scm_iprin1), smob.c
68 (scm_smob_prehistory): Don't handle bignums, reals and complex
69 numbers as subtypes of scm_tc7_smob any more.
70
71 * numbers.h, tags.h (scm_tc16_big, scm_tc16_real,
72 scm_tc16_complex): Moved definitions from tags.h to numbers.h.
73

DH		 742003-09-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
75
76 * numbers.c (scm_make_complex), gc-card.c (scm_i_sweep_card): Use
77 sizeof (scm_t_complex) to determine the memory size of the
78 malloc'd area for complex numbers.

MV		 842003-09-16 Marius Vollmer <mvo@zagadka.de>
85
86 * stime.c (scm_current_time): 'time' does not set errno so don't
87 use SCM_SYSERROR for reporting errors.

DH		 892003-09-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
90
91 This set of patches eliminates the dependency between the
92 implementation of evaluator specific memoization codes and special
93 constants like #f, '() etc. ('flags'), which are not evaluator
94 specific. The goal is to remove definitions of evaluator
95 memoization codes completely from the public interface. This will
96 make it possible to experiment more freely with optimizations of
97 guile's internal representation of memoized code.
98
99 * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
100
101 * print.c (iflagnames): New array, holding the printed names of
102 guile's special constants ('flags').
103
104 (scm_isymnames): Now holds only the printed names of the
105 memoization codes.
106
107 (scm_iprin1): Separate the handling of memoization codes and
108 guile's special constants.
109
110 * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
111 SCM_IFLAGNUM): new
112
113 (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
114 SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
115 SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
116 SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
117 SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
118 values.
119
120 (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
121
122 (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
123 tc9 macros and scm_tc9_flag.
124

MV		 1252003-09-15 Marius Vollmer <mvo@zagadka.de>
126
127 * posix.c (scm_setgroups): Check that the gid list is not too
128 long. Thanks to Paul Jarc!
129
22f2cf2d
DH		 1302003-09-14 Dirk Herrmann <D.Herrmann@tu-bs.de>
131
132 * tags.h: Reduced the number of short instructions from 14 to 13.
133 The typecode of the former 14th short instruction is now used to
134 represent long instructions. Changed some comments to reflect
135 this fact.
136
137 (SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
138 previously used by SCM_IM_DEFINE.
139
140 (SCM_IM_DEFINE): Turned into a long instruction.
141
142 * eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
143 instruction.
144
145 * eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
146 code that is separate from all instructions, one level of dispatch
147 for long instructions can be eliminated.
148
149 * print.c (scm_isymnames): Removed some commented code.
150
62f548e1
MV		 1512003-09-12 Marius Vollmer <mvo@zagadka.de>
152
97a61c5f
MV		 153 * __scm.h (SCM_FENCE): Use __memory_barrier with the Intel
154 compiler on IA64.
155
50e0ba57
MV		 156 * hashtab.h (scm_tc16_hashtable): Added "extern" declaration.
157
158 * modules.c (scm_module_reverse_lookup): Check that the obarray
159 really is a hashtable and do nothing if not.
160
62f548e1
MV		 161 * inline.h: Use "extern inline" only with GCC. Use "static
162 inline" else.
163
0d5e3480
DH		 1642003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
165
166 * numbers.h (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Removed uses
167 of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
168
169 * numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
170 SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
171 deprecated.h.
172
6b412e91
DH		 1732003-09-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
174
175 * eq.c (scm_eqv_p, scm_equal_p): Removed uses of
176 SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
177
178 * eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
179 0.0==some_expression to some_expression==0.0. The latter is
180 better readable. The former is preferred by some people, since it
181 leads to a compiler error when confusing == with =. However, when
182 using gcc, a warning will be issued if in an if-statement an
183 assigment appears. Since many Guile developers are using gcc,
184 such errors will not remain unnoticed anyway. We can therefore
185 focus on better readability.
186

DH		 1872003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
188
189 * tags.h: Added description of Guile's type system. Removed some

199 * numbers.h (SCM_MAKINUM): Define in terms of scm_tc2_int.
200
201 (SCM_INEXACTP, SCM_REALP, SCM_COMPLEXP): Define in terms of the
202 respective SLOPPY macro.
203

DH		 2042003-09-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
205
206 * eq.c (scm_equal_p): Use SCM_TYP7 to check if an object is of
207 type string, not SCM_TYP7S.

212 2s-complement.
213
53bb8782
KR		 214 * stime.c (scm_strptime): Add comment about glibc strptime %s and

224
225 * numbers.c (scm_lognot): Rewrite using ~ and mpz_com, for directness
226 and to have non-integer types rejected as per other logical funcs.

246 macros while defining functions.
247
248 * simpos.c (getenv): Use <stdlib.h> for prototype.

253
254 * srcprop.c (scm_source_properties): Return plist from hash if it's a

258
259 * properties.c (scm_primitive_property_ref): In docstring, note

278
20703ac4
MV		 279 * __scm.h (SCM_C_INLINE_KEYWORD): New.
280 * numbers.c: Use it in place of SCM_C_INLINE so that the code
281 compiles when SCM_C_INLINE is undefined.
282
59c4bb82
DH		 2832003-07-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
284
285 * __scm.h: Reformulated the architecture and compiler properties
286 in terms of properties of scm_t_bits and SCM variables rather than
287 in terms of c standard types. This is since it is not known which
288 of the standard types scm_t_bits and SCM variables will be defined
289 to.

336 * threads.c (scm_call_with_new_thread): In docstring, use "( )"
337 outside @var to quieten makeinfo, and use @code.

342 (increase_mtrigger): new function, separate debug registering and
343 mtrigger administration.
344 (scm_gc_realloc): bugfix: do mtrigger administration before the

346 memory. Thanks to Sam Hocevar for pointing this out.
347 (scm_gc_realloc): use scm_malloc_reregister instead of
348 unregistering and registering in sequence.

397 to be functions instead of macros.
398
399 * threads.c: Conditionalized inclusion of <sys/time.h> and
400 <unistd.h>.
401 (scm_getspecific, scm_setspecific): Made these two function
402 real part of the API.
403
404 * posix.c (s_scm_putenv): Added some code to make a
405 (putenv "FOO="), i.e. setting an empty string, work also on

471
472 * eval.c, eval.h (SCM_MAKE_ILOC): Removed from eval.h and placed
473 into eval.c. This definition was not part of the API in any
474 officially released version of guile and thus does not need to go
475 through a phase of deprecation.

495 This set of patches separates the representation of the cxr family
496 of functions (car, cdr etc.) from the dsubr family of functions
497 (i. e. functions that take a double precision floating point
498 argument). Further, the algorithm for handling the cxr function
499 is improved.

716 The purpose of this patch is to make guile's internal memoizers
717 distinguishable from memoizing macros created on the scheme level
718 or from user provided primitive memoizing macros. The reason is,
719 that the internal memoizers are the only ones that are allowed to
720 transform their scheme input into memoizer byte code, while all
721 other memoizing macros may only transform scheme code into new
722 scheme code.
723
724 To achieve this, a new macro type 'builtin-macro!' is introduced.
725 Currently, 'builtin-macro!'s are handled as memoizing macros, but
726 this will change when the memoizer and executor are separated.
727
728 * macros.[ch] (scm_i_makbimacro): New.

735 primitive builtin-macros now.
736
737 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
738 builtin-macros are handled equally to memoizing macros.

1652 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
1653 (current number of prehistory bindings; hashtable code will select
1654 a prime which is greater than this value).

1669 The following changes introduce the use of resizable hash tables
1670 throughout Guile. It also renames the old *-hash-table* functions
1671 to *-alist-vector* and places them, together with the rest of the
1672 weak vector support, in the module (ice-9 weak-vector). We should
1673 probably introduce a new, better, API for weak references, for
1674 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
1675 look like and are used like ordinary pairs.)
1676

1859 This change makes it possible for one thread to do lazy sweeping
1860 while other threads are running. Now only the mark phase need to
1861 have all threads asleep. We should look further into this issue.
1862 Presently, I've put the locking of scm_i_sweep_mutex at
1863 "conservative" places due to my current lack of knowledge about
1864 the garbage collector. Please feel free to restrict these regions
1865 further to allow for maximal parallelism!
1866
1867 * gc.c, gc.h (scm_i_sweep_mutex): New mutex.
1868
1869 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
1870 scm_gc_register_collectable_memory): Substitute locking of
1871 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
1872 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
1873 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
1874 the single-thread section (which now only contains the mark
1875 phase).
1876 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
1877 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
1878
1879 * threads.c (gc_section_mutex): Removed.

MD		 2055 These changes are the start of support for preemptive
2056 multithreading. Marius and I have agreed that I commit this code
2057 into the repository although it isn't thoroughly tested and surely
2058 introduces many bugs. The bugs should only be exposed when using
2059 threads, though. Signalling and error handling for threads is
2060 very likely broken. Work on making the implementation cleaner and
2061 more efficient is needed.
2062
2063 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
2064 (SCM_NONREC_CRITICAL_SECTION_START,

2089 scm_gc_for_newcell): Put threads to sleep before doing GC-related
2090 heap administration so that those pieces of code are executed
2091 single-threaded. We might consider rewriting these code sections
2092 in terms of a "call_gc_code_singly_threaded" construct instead of
2093 calling the pair of scm_i_thread_put_to_sleep () and
2094 scm_i_thread_wake_up (). Also, we would want to have as many of

2097 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
2098
2099 * inline.h: #include "libguile/threads.h"
2100
2101 * pthread-threads.h: Macros now conform more closely to the

2122 (libpath.h): use GUILE_EFFECTIVE_VERSION to compute
2123 SCM_LIBRARY_DIR.
2124 (version.h): generate this here rather than configure.in. This
2125 approach tracks source edits better (i.e. more immediately).
2126 Might be worth considering for other .in files too.

2130 Reorganized thread package selection. A thread package now only
2131 implements a small set of pthread like functions and Guile
2132 implements the rest on top of that. Guile's implementation is
2133 what the "coop-pthreads" package has been previously. Support for
2134 "coop" threads has been removed until I get time to add it again.
2135
2136 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
2137 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
2138 null-threads.c, coop-pthreads.c.
2139 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
2140 pthread-threads.h.
2141
2142 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
2143
2144 * threads.h: Do not include "libguile/coop-defs.h". Include
2145 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
2146 (previously deprecated) C level thread API prototypes. They are
2147 now in the thread package specific headers, "null-threads.h" and
2148 "pthread-threads.h".
2149 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):
2150 New.
2151 (scm_threads_init): Removed.
2152 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
2153 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
2154 SCM_I_THREAD_SWITCH_COUNT): Define here.
2155 (scm_single_thread_p): Removed.
2156 (scm_call_with_new_thread): Take two args directly instead of list
2157 of two args.
2158 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
2159 SCM_SET_THREAD_LOCAL_DATA): Define here.
2160
2161 * threads.c: Merged with "coop-pthreads.c".
2162
2163 * null-threads.h: Implement pthread-like API as a set of macros.
2164
2165 * pthread-threads.h: New, implement pthread-like API by deferring
2166 to pthread itself.
2167
2168 * init.c (scm_init_guile_1): Do not call scm_init_iselect, which
2169 has been lost in the reorganization.

2173 The following change makes it possible to move procedure
2174 application dispatch outside inner loops. The motivation was
2175 clean implementation of efficient replacements of R5RS primitives
2176 in SRFI-1.
2177
2178 The semantics is clear: scm_trampoline_N returns an optimized
2179 version of scm_call_N (or NULL if the procedure isn't applicable
2180 on N args).
2181
2182 Applying the optimization to map and for-each increases efficiency
2183 noticeably. For example, (map abs ls) is 8 times faster than
2184 before.
2185
2186 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
2187
2188 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
2189
2190 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
2191 (map, for-each): Handle also application on two args as a special
2192 case; Use trampolines.
2193
2194 Other changes:
2195
2196 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
2197 (subr2oless): Removed.
2198 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
2199 vector GC protected.
2200
2201 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
2202 scm_out_of_range.

2225 scm_module_transformer, scm_sym2var, scm_module_reverse_lookup,
2226 scm_system_module_env_p): Don't compare SCM values with C
2227 operators == or !=. Avoid SCM_IMP predicates. Prefer !SCM_FALSEP
2228 over SCM_NFALSEP.

2238
2239 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
2240 part of the API, otherwise it's difficult to write Guile
2241 extensions using non-blocking I/O => moved #include
2242 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
2243
2244 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->

2253 is only for declarations.

2300 start testing it now.
2301

2310 scm_delq_spine_x, really_install_handler, install_handler): New
2311 scheme for triggering signal handlers, to simplify take_signal.
2312 (take_signal): Simplified, to avoid race conditions.
2313 (scm_sigaction_for_thread): Use new Scheme. Validate that thread
2314 hasn't exited yet.
2315
2316 * async.c (scm_async_click): Reset pending_asyncs, handle
2317 signal_asyncs. Don't set cdr of a non-signal async to #f.
2318 (scm_i_queue_async_cell): Do not check cdr of cell for #f, queue
2319 always. Set pending_asyncs.
2320 (scm_system_async_mark_for_thread): Check that thread has not
2321 exited.
2322 (scm_unmask_signals, decrease_block): Call scm_async_click after
2323 block_asyncs becomes zero.
2324

2340 USE_COPT_THREADS to not protect the slot initializers.
2341
2342 * init.c (scm_init_guile_1): Call scm_init_thread_procs. This is
2343 because threads need to be initialized before the stack, but
2344 gsubrs such as scm_timed_condition_variable_wait can only be
2345 created later.
2346
2347 * threads.h: Include "coop-pthreads.h" when requested.

2366 registered procedures.
2367 (scm_wait_condition_variable, scm_timed_wait_condition_variable):
2368 Use the latter as the procedure for "wait-condition-variable",
2369 thus offering a optional timeout parameter to Scheme.
2370 (scm_wait_condition_variable): Implement in terms of
2371 scm_timed_wait_condition_variable.
2372 (scm_mutex_init, scm_mutex_lock, scm_mutex_trylock,

2375 scm_cond_broadcast, scm_cond_destroy): Implement in terms of
2376 scm_make_mutex, etc, and deprecate.
2377 (scm_init_threads): Do not create smobs, leave this to
2378 scm_threads_init. Do not include "threads.x" file.

2387 scm_cond_wait, scm_cond_signal, scm_cond_broadcast,
2388 scm_cond_destory): Do not define, they are now deprecated and
2389 handled by threads.{h,c}.
2390
2391 * null-threads.c (scm_null_mutex, scm_null_cond): Define here.
2392 (scm_threads_init): Create smobs here, using the appropriate
2393 sizes.
