28 * win32-dirent.c: Use malloc() instead of scm_malloc().
29
30 * stime.c (s_scm_strftime): Add a type cast to avoid compiler
31 warning.

34 mingw32 build.
35
36 * modules.c (s_scm_module_import_interface): Renamed local

41
42 * load.c (s_scm_search_path): Fixed absolute and relative
43 path detections for native Windows platforms.
44
45 * gc.h, threads.h: Export some more symbols using SCM_API (necessary
46 to build on mingw32).
47
48 * gc-freelist.c ("s_scm_map_free_list",
49 "s_scm_gc_set_debug_check_freelist_x"): Fixed use of FUNC_NAME.

MD		 76 * __scm.h (SCM_STACK_PTR): New macro. (Cast argument through
77 (void *) in order to avoid an aliasing warning; thanks to Bruce
78 Korb.)
79
80 * stackchk.h (SCM_STACK_OVERFLOW_P): Use SCM_STACK_PTR.
81

116 yyget_text, yyset_lineno, yyset_in, yyset_out, yyget_debug,
117 yyset_debug, yylex_destroy): Added prototypes (otherwise we'll get
118 a compilation error if error-on-warning is enabled).
119

MV		 1202003-05-17 Marius Vollmer <mvo@zagadka.de>
121
122 * c-tokenize.lex: Gobble up complete lines after a '#'. This
123 removes preprocessor directives from the snarfage that might
124 otherwise confuse us. These directives appear when compiling with
125 "-g3", for example.

170 mpz_sizeinbase to account for it looking at absolute value where we
171 want ones-complement.
172
173 * numbers.c (scm_gcd): In bignum/inum, don't pass yy==0 to mpz_gcd_ui
174 since we're only using the ulong return value, and x might not fit.

193
194 The purpose of this patch is to make guile's internal memoizers
195 distinguishable from memoizing macros created on the scheme level
196 or from user provided primitive memoizing macros. The reason is,
197 that the internal memoizers are the only ones that are allowed to
198 transform their scheme input into memoizer byte code, while all
199 other memoizing macros may only transform scheme code into new
200 scheme code.
201
202 To achieve this, a new macro type 'builtin-macro!' is introduced.
203 Currently, 'builtin-macro!'s are handled as memoizing macros, but
204 this will change when the memoizer and executor are separated.
205
206 * macros.[ch] (scm_i_makbimacro): New.
207
208 * macros.h (SCM_BUILTIN_MACRO_P): New.
209
210 * macros.c (macro_print, scm_macro_type): Support builtin-macro!s.
211
212 * eval.c, goops.c: All of guile's primitive memoizing macros are
213 primitive builtin-macros now.
214
215 * eval.c (scm_macroexp, SCM_CEVAL): Make sure the primitive
216 builtin-macros are handled equally to memoizing macros.

248 macro was introduced in anticipation of GOOPS method compilation
249 code.)

DH		 2532003-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
254
255 * eval.c, goops.c (@dispatch, @slot-ref, @slot-set!): Move the
256 instructions that bind the macros on the scheme level back to
257 goops.c in order to make sure again that the bindings go into the
258 (oop goops) module and are not visible from the outside.

263 macros into different sections of the file and ordered the
264 memoizers alphabetically.

273 Partially reverted patch from 2003-04-23 in oder to find a better
274 compromise between readability and debuggability.

279 scm_m_atslot_set_x, scm_m_atdispatch): Move the declarations and
280 definitions of the special goops memoizers from goops.[ch] to
281 eval.[ch]. Hmm... it seems that scm_m_atdispatch is not used
282 throughout guile.

305 This set of patches contains no functional changes, only debatable
306 minor stylistic ones. Still, in order to prepare a patch between
307 my local copy and the CVS version, I decided to submit the changes
308 below. Then, the patch will hopefully only contain relevant
309 modifications :-)
310
311 * eval.c (iqq): Added const specifier.
312
313 * eval.c (scm_trampoline_0, scm_trampoline_1, scm_trampoline_2):
314 Use NULL instead of 0 to indicate that a pointer is returned.
315 Removed some misleading 'fall through' comments.
316
317 * eval.c (scm_i_call_closure_0, call_closure_1, call_closure_2):
318 Split up long expressions into smaller ones to be more debugging
319 friendly.

344 (subr2less, lsubrless, closureless, applyless, scm_cmp_function,
345 cmp_fun_t): Removed.
346
347 (compare_function): Added.
348
349 * sort.c (quicksort, SWAP, stack_node): Replaced pointer
350 arithmetics with index arithmetics. Changed quicksort to work on
351 an array of SCM values instead of an array of characters. Avoid
352 bytewise copying of SCM elements. Avoid allocating memory on the
353 stack with alloca. Fixed some comments.

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

412 scm_m_generalized_set_x, scm_init_evalext): Move the declaration
413 and definition of the memoizer for the generalized set! macro from
414 evalext.[ch] to eval.[ch]. Use the SCM_SYNTAX snarfer macro to
415 define the macro object.
416

913
914 * inline.h: #include "libguile/__scm.h" at the top. Change code
915 to use SCM_C_INLINE and SCM_INLINE_C_INCLUDINT_INLINE_H to decide
916 what to do instead of creating a new public #define. Rename usage
917 of USE_COOP_THREADS to SCM_USE_COOP_THREADS. Rename usage of
918 USE_NULL_THREADS to SCM_USE_NULL_THREADS. Rename usage of

921 * inline.c: rearrange handling -- now we just #define
922 SCM_INLINE_C_INCLUDING_INLINE_H to 1 and #include
923 "libguile/inline.h". scmconfig.h will define SCM_C_INLINE as
924 appropriate, and we use that in inline.h along with the above
925 define to determine how to respond.

928 HAVE_ARRAYS to SCM_HAVE_ARRAYS.

1036 * Makefile.am: scmconfig.h is now generated by building and
1037 running gen-scmconfig.h and capturing its output. gen-scmconfig
1038 uses config.h and the configure.in generated gen-scmconfig.h to
1039 decide what to output. See gen-scmconfig.c for details.
1040 (noinst_PROGRAMS): add gen-scmconfig.
1041 (gen_scmconfig_SOURCES): new variable.
1042 (gen-scmconfig.$(OBJEXT)): new target - be careful to handle
1043 cross-compiling right.

1128 (since hash tables now adapt their size).
1129
1130 * modules.c (scm_modules_prehistory): Changed from 2001 to 1533
1131 (current number of prehistory bindings; hashtable code will select
1132 a prime which is greater than this value).
1133

MD		 1145 * hooks.c (scm_c_hook_add): Fixed bug in append mode.
1146
1147 The following changes introduce the use of resizable hash tables
1148 throughout Guile. It also renames the old *-hash-table* functions
1149 to *-alist-vector* and places them, together with the rest of the
1150 weak vector support, in the module (ice-9 weak-vector). We should
1151 probably introduce a new, better, API for weak references, for
1152 example "weak pairs" a la MIT-Scheme. (In Chez scheme, they even
1153 look like and are used like ordinary pairs.)
1154
1155 * environments.c (obarray_enter, obarray_retrieve, obarray_remove,
1156 leaf_environment_fold, obarray_remove_all): Use hashtable
1157 accessors.

1337 This change makes it possible for one thread to do lazy sweeping
1338 while other threads are running. Now only the mark phase need to
1339 have all threads asleep. We should look further into this issue.
1340 Presently, I've put the locking of scm_i_sweep_mutex at
1341 "conservative" places due to my current lack of knowledge about
1342 the garbage collector. Please feel free to restrict these regions
1343 further to allow for maximal parallelism!
1344

1346
1347 * gc.c (scm_gc_for_newcell), gc-malloc.c (scm_realloc,
1348 scm_gc_register_collectable_memory): Substitute locking of
1349 scm_i_sweep_mutex for calls to scm_i_thread_put_to_sleep.
1350 (scm_igc): Lock sweep mutex here instead of in callers; Calls to
1351 scm_i_thread_put_to_sleep/scm_i_thread_wake_up used to demarkate
1352 the single-thread section (which now only contains the mark
1353 phase).
1354 (scm_gc): Don't lock sweeo mutex here since scm_igc locks it;
1355 Removed SCM_DEFER/ALLOW_INTS. Simply call scm_igc directly.
1356
1357 * threads.c (gc_section_mutex): Removed.

1418 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
1419 SCM_REC_CRITICAL_SECTION_END): Removed.
1420
1421 * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
1422 direct calls to scm_rec_mutex_lock / unlock around the three calls
1423 to scm_m_expand_body.
1424

MD		 1533 These changes are the start of support for preemptive
1534 multithreading. Marius and I have agreed that I commit this code
1535 into the repository although it isn't thoroughly tested and surely
1536 introduces many bugs. The bugs should only be exposed when using
1537 threads, though. Signalling and error handling for threads is
1538 very likely broken. Work on making the implementation cleaner and
1539 more efficient is needed.
1540
1541 * __scm.h (SCM_ALLOW_INTS_ONLY): Removed.
1542 (SCM_NONREC_CRITICAL_SECTION_START,
1543 SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
1544 SCM_REC_CRITICAL_SECTION_END): New macros.
1545 (SCM_CRITICAL_SECTION_START/END): Defined here.

1557 access.

1565
1566 * gc.c (scm_i_expensive_validation_check, scm_gc,
1567 scm_gc_for_newcell): Put threads to sleep before doing GC-related
1568 heap administration so that those pieces of code are executed
1569 single-threaded. We might consider rewriting these code sections
1570 in terms of a "call_gc_code_singly_threaded" construct instead of
1571 calling the pair of scm_i_thread_put_to_sleep () and
1572 scm_i_thread_wake_up (). Also, we would want to have as many of
1573 these sections eleminated.
1574
1575 * init.c (scm_init_guile_1): Call scm_threads_prehistory.
1576
1577 * inline.h: #include "libguile/threads.h"

1608 Reorganized thread package selection. A thread package now only
1609 implements a small set of pthread like functions and Guile
1610 implements the rest on top of that. Guile's implementation is
1611 what the "coop-pthreads" package has been previously. Support for
1612 "coop" threads has been removed until I get time to add it again.
1613
1614 * Makefile.am (libguile_la_SOURCES): Removed iselect.c.
1615 (noinst_HEADERS): Removed coop-threads.c, coop-threads.h, coop.c,
1616 null-threads.c, coop-pthreads.c.
1617 (modinclude_HEADERS): Removed coop-defs.h, coop-pthreads.h. Added
1618 pthread-threads.h.
1619
1620 * validate.h (SCM_VALIDATE_THREAD): Moved to threads.h.
1621
1622 * threads.h: Do not include "libguile/coop-defs.h". Include
1623 "libguile/pthread-threads.h" for USE_COPT_THREADS. Removed
1624 (previously deprecated) C level thread API prototypes. They are
1625 now in the thread package specific headers, "null-threads.h" and
1626 "pthread-threads.h".
1627 (SCM_VALIDATE_THREAD, SCM_VALIDATE_MUTEX, SCM_VALIDATE_CONDVAR):

1630 (SCM_CRITICAL_SECTION_START, SCM_CRITICAL_SECTION_END,
1631 SCM_THREAD_SWITCHING_CODE, scm_i_switch_counter,
1632 SCM_I_THREAD_SWITCH_COUNT): Define here.
1633 (scm_single_thread_p): Removed.
1634 (scm_call_with_new_thread): Take two args directly instead of list
1635 of two args.
1636 (scm_i_thread_data, scm_i_set_thread_data, SCM_THREAD_LOCAL_DATA,
1637 SCM_SET_THREAD_LOCAL_DATA): Define here.
1638

1644 to pthread itself.
1645

1647 has been lost in the reorganization.

1651 The following change makes it possible to move procedure
1652 application dispatch outside inner loops. The motivation was
1653 clean implementation of efficient replacements of R5RS primitives
1654 in SRFI-1.
1655
1656 The semantics is clear: scm_trampoline_N returns an optimized
1657 version of scm_call_N (or NULL if the procedure isn't applicable
1658 on N args).
1659
1660 Applying the optimization to map and for-each increases efficiency
1661 noticeably. For example, (map abs ls) is 8 times faster than
1662 before.
1663
1664 * eval.h (scm_t_trampoline_1, scm_t_trampoline_2): New types.
1665
1666 * eval.c, eval.h (scm_trampoline_1, scm_trampoline_2): New functions.
1667
1668 * eval.c (call_subr2_2, call_lsubr_2, call_closure_2): New functions;
1669 (map, for-each): Handle also application on two args as a special
1670 case; Use trampolines.
1671
1672 Other changes:
1673
1674 * sort.c (scm_cmp_function): Choose subr2less for scm_tc7_subr_2o;
1675 (subr2oless): Removed.
1676 (scm_restricted_vector_sort_x): Use scm_return_first to keep the
1677 vector GC protected.
1678
1679 * eval.c (check_map_args): Use scm_out_of_range_pos instead of
1680 scm_out_of_range.

1717 * coop-pthreads.c, coop-pthreads.h: scm_internal_select should be
1718 part of the API, otherwise it's difficult to write Guile
1719 extensions using non-blocking I/O => moved #include
1720 "libguile/iselect.h" from coop-pthreads.c --> coop-pthreads.h.
1721
1722 * coop-pthreads.c (scm_unlock_mutex): Changed s_lock_mutex -->
