I hope it doesn't break anybody's - sed. we'll see. (note: this is lossy trimming, i.e. the spill - isn't wrapped around but actually chopped off. this seemed to me - safe because the current snarfer doesn't understand multi-line - cookies anyway. in the long term, it would be nice not to depend - on AWK for anything.) - - * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted - the previous change to this macros, after deciding to torture the - snarfer instead. - -2000-05-21 Michael Livshin - - * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought - the yucky, ugly and nasty conditional compilation back. sorry, - but it was either that or requiring GAWK to build Guile. - (lots of places): removed the code that implemented the old GC - scheme. - - * init.c (scm_boot_guile_1): removed the code conditioned on - !GUILE_NEW_GC_SCHEME. - - * __scm.h: (GUILE_NEW_GC_SCHEME): removed. - - * gc.c (scm_protect_object, scm_unprotect_object): change the - implementation to more efficient (at least in the time complexity - sense). the calls should now also be thread-safe -- I suspect - that people expect them to be.

These names should - be changed, though, since the macros are not only pair related. - - (SCMPTR): Deleted. - - * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, - SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, - SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, - SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, - SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, - SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from - tags.h and pairs.h. - -2000-03-25 Dirk Herrmann - - * tags.h (SCM_STRICT_TYPING): New macro that, if defined, - activates strict compile time type checking for variables of - type SCM. - (SCM, SCM_PACK, SCM_UNPACK): Define according to whether - SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined. - (SCM_EQ_P): Defined as a macro equivalent for eq?. - -2000-03-25 Dirk Herrmann - - * tags.h (SCM_POINTERS_MUNGED): Removed. - - * gc.c (scm_gc_sweep, init_heap_seg): Removed use of - SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM. - -2000-03-24 Dirk Herrmann - - * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3], - SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE, - SCM_SET_CELL_TYPE): Added a set of low level macros for accessing - cell entries. - (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3]. - - * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the - newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros. - -2000-03-23 Mikael Djurfeldt - - * tags.h: Disabled definition of SCM_VOIDP_TEST. - - Defining SCM as void * introduces problems which haven't been - handled yet. Developers who work with these issues can enable it - in their working copies. - - Disabling this definition exposes a set of newly introduced and - older misuses of types which causes warning messages during - compilation. We'll fix this successively. - - * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X - in order to obtain a value of type SCM. - (scm_cellp): Updated with new changes to scm_mark_locations. - - * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM. - - * continuations.c (scm_make_cont): Removed cast of size_t into - long. - - * symbols.h (SCM_SETCHARS): Cast second arg into SCM. - -2000-03-22 Dirk Herrmann - - * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for - shifting, not constant.

Gives quick startup - without extra heap allocation. - -2000-03-20 Dirk Herrmann - - * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should - already be a C value. No need to unpack it. - - * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t - if we know it fits into an inum. - - * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a - field of long values. In contrast, SCM_VELTS accesses a field of - SCM values. - -2000-03-20 Mikael Djurfeldt - - * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger - etc. - (scm_gc_yield_1): New variable: Holds previous yield.

It makes Guile fast, but still - contains bugs. - - * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of - allocating heap. The basic idea is to trigger GC every Nth - allocated cell and grow heap when free list runs out. The scheme - has been extended so that GC isn't triggered until all remaining - cells are used. The implementation is also prepared for - development in the direction of POSIX threads. - - * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5, - SCM_EXPHEAP should return half of the heap size. - -2000-03-14 Mikael Djurfeldt - - The following change to init.c is only enabled if Guile was - configured with --enable-guile-debug. - - * init.c (scm_i_getenv_int): New function. - (scm_boot_guile_1): Use the environment variables - GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if - they exist.

(Thanks to Keisuke Nishida.) - -2000-03-14 Mikael Djurfeldt - - * init.c (scm_boot_guile_1): Use same initial segment size for - 1-word and 2-word segments. Having the smaller size causes Guile - to GC too often. Obviously something needs to be done to allow - for a smaller 2-word segment without this to happen. (The amount - of heap for each type should be automatically adapted to the - application somehow.) - - [Almost all of these changes should be documented in the NEWS - file.] - - * gc.h (scm_freelist_t): New type. - - * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists. - - * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that - all of Guile basics fits into one segment and there suitable room - for work. - (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5 - instead of 2. - (scm_freelist, scm_freelist2): Now of type scm_freelist_t. - Freelists now contains information about object span, cells - collected and amount of cells in heap segments belonging to the - list. - (scm_heap_size, scm_gc_cells_collected): Removed. - - * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells). - - * Makefile.am (libguile_la_LDFLAGS): Bumped library version - number. - - * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c, - numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive - rewrite of handling of real and complex numbers. - (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been - removed along with the support for floats. (Float vectors are - still supported.) - - * tags.h (scm_tcs_bignums): Removed. - (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big. - Use SCM_BIGSIGN(x) to test for sign! - (scm_tc16_big): The new bignum type. - (SCM_REAL_PART, SCM_IMAG_PART): Removed. - - * numbers.h (SCM_BIGSIGN): Sign moved to bit 16. - (scm_makdbl): Deprecated. - (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros. - (SCM_SINGP): Deprecated. - (SCM_FLO): Removed. - (SCM_INEXP, SCM_CPLXP): Deprecated. - (SCM_INEXACTP, SCM_COMPLEXP): New macros. - (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from - SCM_REAL, SCM_IMAG (and now only valid for complex numbers). - (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both - for doubles and complex numbers. - (SCM_REAL_VALUE): New selector for doubles. - (scm_double_t, scm_complex_t): New types. - (scm_dbl): Removed. - - * numbers.c (scm_floprint, scm_floequal): Removed. - (scm_print_real, scm_print_complex, scm_real_equalp, - scm_complex_equalp): New functions. - - * unif.c (scm_makflo): Removed. - - * smob.h (SCM_SMOB_PREDICATE): New macro. - (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3, - SCM_RETURN_NEWSMOB3): New macros. - -1999-11-21 Michael Livshin - - The following changes implement primitive support for double cells - (i.e. four-word cells) and change the representation of some - things to multi-cells instead of cons+malloc. (Applied and - modified by mdj.) - - * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL. - (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive - multi-cell access macros (used by the ones below). - (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access - macros. - - * gc.c (scm_freelist2): multi-cell freelists. - (inner_map_free_list): map_free_list, parameterized on ncells. - "nn cells in segment mm" was misleading for ncells > 1; changed to - "objects". still print cells too, though. - (scm_map_free_list): rewritten using inner_map_free_list. - (scm_check_freelist): get freelist as parameter, since now we have - more than one. - (scm_debug_newcell2): multi-cell variants of - scm_debug_newcell. - (scm_gc_for_newcell): take ncells and freelist pointer as - parameters. - (scm_gc_mark): add case for tc7_pws (procedures with setters are - now double cells). - (scm_gc_sweep): don't free the float data, since it's not malloced - anymore. - (init_heap_seg): didn't understand what n_new_objects stood for, - so changed to n_new_cells. - (make_initial_segment): new function, makes an initial segment - according to given ncells. - (scm_init_storage): call make_initial_segment, for ncells={1,2,3}. - - * numbers.c (scm_makdbl): no malloc'ing needed, so the - {DEFER,ALLOW}_INTS thing removed. - - * numbers.h (struct scm_dbl): changed to represent a double cell, - with the number in the second half. - - * dynwind.c: changed the wind-guards representation to double - cell. - - * procs.c, procs.h: changed the procedure-with-setter representation - to double cell. - - * async.c, async.h: made async representation a double cell. - - * dynl.c: made dynamic_obj representation a double cell. - -2000-03-13 Gary Houston - - * ports.c (flush_void_port): renamed to flush_port_default. - (end_input_void_port): renamed to end_input_default. - - * init.c (scm_standard_stream_to_port): create a void port instead - of opening /dev/null if the standard file descriptors are bad. - advantages: no portability problems, doesn't waste a file descriptor, - simplifies the code (thanks to Marius for the idea). - - * vports.c (s_scm_make_soft_port): call scm_port_non_buffer. - - * void ports: make reading from a void port give EOF instead of - segv: - * ports.c (s_scm_sys_make_void_port): modified docstring. - (fill_input_void_port): new proc. - (scm_init_ports): set up fill_input_void_port. - * ports.c (scm_port_non_buffer): new proc. - (scm_void_port): call scm_port_non_buffer. - - * fports.c (scm_setvbuf): docstring: remove the fcntl documentation - which was incorrectly appended. - -2000-03-13 Mikael Djurfeldt - - * guile-doc-snarf.in: Don't use absolute path for `sed'.

Also dropped trailing - (rnrs) note. - - * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the - function with scm_make_subr_opt w/ last arg of 0 so it is not - visible at the Scheme level.

Badros - - * guile-doc-snarf.in: Use new $fullfilename for running - guile-func-name-check, and put "$fullfilename" and "$filename" in - quotes at uses to make sure re-splitting on whitespace does not - occur (so filenames w/ embedded whitespace would work okay, though - I sure hope we never have to deal with that! :-) ).

The strange SCM_NIMP tests are replaced by - SCM_CONSP tests that more closely reflect the intended semantics. - However, we don't get a performance penalty here, because the - SCM_CONSP test was performed by the ALISTCELL test anyway. * The - extremely ugly use of ASRTGO macros was removed: The calls to - ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a - label parameter that only exists when SCM_RECKLESS is not defined. - This works, because ASRTGO itself is defined in a way that it only - makes use of the label parameter if SCM_RECKLESS is not defined - (shudder!). Does guile make at all use of the possibility to - define SCM_RECKLESS? * Codesize is likely to be reduced, since - instead of two calls to SCM_ASSERT performed by the ALISTCELL test - we now only get one test. - - * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use - SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on - some variables in `list?'. Fix `reverse' and `reverse!' - primitives to handle improper lists better. - -Wed Jan 5 11:24:53 2000 Greg J. Badros - - * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_* - macros and SCM_DEFINE macros to match GNU coding standards. - -Wed Jan 5 11:04:24 2000 Greg J.

Badros - - * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a - SCM_VALIDATE instead of 1 to avoid a check on the argument (since - it's not the actual name of the formal). - - * guile-snarf.awk.in: Do argument/number mismatch checking and - print warnings in an Emacs compile-mode parseable format. - - * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/ - SCM_OUTOFRANGE as 3rd argument. - - * random.c: Fix argument/number mismatch (that I introduced :-( ). - - * __scm.h: Do not #define SCM_ARG* when snarfing; - lets us distinguish between 1 and SCM_ARG1 when snarfing as only - the former (using the number) requires the argument to match the - formal in the current argument snarfing check. - - * snarf.h: Give new definition of SCM_ASSERT when in - snarfing mode to output a lexically-identifiable sequence that the - guile-snarf.awk script uses to verify argument/position matching. - - * ramap.c: Remove extraneous #undef FUNC_NAME. - -Wed Jan 5 08:36:38 2000 Greg J. Badros - - * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the - current version of the same functionality; it writes the .x output - to stdout instead of directly into the file. - -Wed Jan 5 08:15:04 2000 Greg J. Badros - - * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c, - posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now - redundant with the safer macros. Patch from Dirk Hermann applied - by hand. Thanks Dirk! - - * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some - uses in random.c. - - * ramap.c: whitespace change. - -Tue Jan 4 14:21:35 2000 Greg J. Badros - - * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP - removals from Dirk Hermann. - - * alist.c: Rename formals to match the parameter names in the - documentation, updates to documentation.

Badros + + * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout. + +Thu Jan 6 11:22:53 2000 Greg J. Badros + + * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1 + instead of GUILE_PROC. + +Thu Jan 6 11:21:49 2000 Greg J. Badros + + * alist.c: Do not report mismatch errors on some uses of `tmp' (do + this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS + macro call. + +Thu Jan 6 09:54:33 2000 Dirk Herrmann --gjb applied + + * scm_validate.h: Remove some redundant NIMP tests. + + * alist.c: minimize scope of the tmp variables, and initialize + them when declared. The strange SCM_NIMP tests are replaced by + SCM_CONSP tests that more closely reflect the intended semantics. + However, we don't get a performance penalty here, because the + SCM_CONSP test was performed by the ALISTCELL test anyway. * The + extremely ugly use of ASRTGO macros was removed: The calls to + ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a + label parameter that only exists when SCM_RECKLESS is not defined. + This works, because ASRTGO itself is defined in a way that it only + makes use of the label parameter if SCM_RECKLESS is not defined + (shudder!). Does guile make at all use of the possibility to + define SCM_RECKLESS? * Codesize is likely to be reduced, since + instead of two calls to SCM_ASSERT performed by the ALISTCELL test + we now only get one test. + + * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use + SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on + some variables in `list?'. Fix `reverse' and `reverse!' + primitives to handle improper lists better. + +Wed Jan 5 11:24:53 2000 Greg J. Badros + + * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_* + macros and SCM_DEFINE macros to match GNU coding standards. + +Wed Jan 5 11:04:24 2000 Greg J. Badros + + * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE. + +Wed Jan 5 10:59:06 2000 Greg J. Badros + + * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for + better consistency with the names of other SCM_VALIDATE_ macros + and better conformance to guile naming policy. + +Wed Jan 5 10:50:39 2000 Greg J. Badros + + * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a + SCM_VALIDATE instead of 1 to avoid a check on the argument (since + it's not the actual name of the formal). + + * guile-snarf.awk.in: Do argument/number mismatch checking and + print warnings in an Emacs compile-mode parseable format. + + * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/ + SCM_OUTOFRANGE as 3rd argument. + + * random.c: Fix argument/number mismatch (that I introduced :-( ). + + * __scm.h: Do not #define SCM_ARG* when snarfing; + lets us distinguish between 1 and SCM_ARG1 when snarfing as only + the former (using the number) requires the argument to match the + formal in the current argument snarfing check. + + * snarf.h: Give new definition of SCM_ASSERT when in + snarfing mode to output a lexically-identifiable sequence that the + guile-snarf.awk script uses to verify argument/position matching. + + * ramap.c: Remove extraneous #undef FUNC_NAME. + +Wed Jan 5 08:36:38 2000 Greg J. Badros + + * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the + current version of the same functionality; it writes the .x output + to stdout instead of directly into the file. + +Wed Jan 5 08:15:04 2000 Greg J. Badros + + * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c, + posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now + redundant with the safer macros. Patch from Dirk Hermann applied + by hand. Thanks Dirk! + + * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some + uses in random.c. + + * ramap.c: whitespace change. + +Tue Jan 4 14:21:35 2000 Greg J. Badros + + * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP + removals from Dirk Hermann. + + * alist.c: Rename formals to match the parameter names in the + documentation, updates to documentation. Thanks Dirk Hermann! + +2000-01-04 Mikael Djurfeldt + + * eval.c (SCM_CEVAL): Reverse order of + scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P + (Thanks to Brad Knotwell.) + +Mon Jan 3 08:30:02 2000 Greg Harvey (applied --01/03/00 gjb) + + * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly + allocated cell. + + * pairs.h: Added a comment about the need for the SCM_SETCAR in + SCM_NEWCELL macro. + +Mon Jan 3 08:25:19 2000 Greg J. Badros + + * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More + SCM_NIMP tests that were redundant are now eliminated.
