Badros <gjb@cs.washington.edu> SCM_NIMP tests that were redundant are now eliminated. Patches from Dirk Hermann applied by hand. -1999-12-28 Gary Houston <ghouston@arglist.com> - - * posix.c (scm_waitpid): move the HAVE_WAITPID test out of the - procedure body, so that the procedure is left undefined if waitpid - is not available. previously in this case the procedure was - defined but would raise a system-error when called, which is - pointless. I intend to make the same change for other procedures - and deprecate SCM_SYSMISSING and scm_sysmissing. - -1999-12-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * feature.c (s_scm_add_hook_x): Call scm_wrong_type_arg instead of - scm_misc_error when add-hook! is passed a procedure of wring - arity. (Thanks to Greg Harvey.) - -1999-12-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * macros.c (scm_make_synt): Use scm_make_subr_opt to make the - transformer subr. (Thanks to Bill Schottstaedt.) - -1999-12-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * objects.c (scm_class_of): Bugfix: Inserted missing SCM_CDR - setting struct table class. - -Sun Dec 19 10:22:34 1999 Greg J. Badros <gjb@cs.washington.edu> - - * threads.c, mit-pthreads.c, list.c, coop.c: Remove K&R - prototypes; just use ANSI C prototypes. I'm not sure how - mit-pthreads.c ever compiled -- it still doesn't for me, but the - normal make procedure does not try to build it anyway (even - --with-threads I get the other threads code building) so I'm not - too worried about it. - -Sat Dec 18 16:58:34 1999 Greg J. Badros <gjb@cs.washington.edu> - - * tags.h (SCM_CONSP, SCM_NCONSP): Define these in terms of - SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this - in terms of SCM_SLOPPY_NCONSP instead of repeating the - expression. - - * symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and - define latter in terms of sloppy variant. - - * strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and - define latter in terms of sloppy variant. - - * scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor - out the commonality of the various basic SCM_VALIDATE_foop - macros. Use SCM_MAKE_VALIDATE macro where possible. Fix - SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does - coercion to an integer which is more advanced than desired and - SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE - appropriately for the various _MIN, _MAX, _RANGE macros. Drop - some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted - SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as - part of its SCM_CONSP test). - - * socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use - SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS. - -Sat Dec 18 15:33:05 1999 Greg J. Badros <gjb@cs.washington.edu> - - * dynl.c: Added #include "scm_validate.h" - -Sat Dec 18 15:22:10 1999 Greg J. Badros <gjb@cs.washington.edu> - - * alist.c, chars.c, dynl.c, net_db.c, numbers.c, unif.c: Use - SCM_NUM2ULONG instead of scm_num2ulong; SCM_NUM2LONG instead of - scm_num2long; SCM_WTA instead of scm_wta. Only done for when - FUNC_NAME was used as an argument of the macro and the formal - argument name was the explicit argument in the old function call. - These were just missed in my first pass of changes. - -1999-12-18 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> - - * guile-doc-snarf.in (filename): Strip path to source dir before - touching the .x-files. - -1999-12-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * debug.c (scm_reverse_lookup): Bugfix: Reinserted SCM_NIMP. - - * eval.c (SCM_CEVAL): Removed check for unbound slot in - SCM_IM_SLOT_REF. (This is now handled in a smarter way in GOOPS.) - -1999-12-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros. - (SCM_ECONSP): Version which doesn't mix && and || without - parenthesis. - (SCM_NECONSP): Bugfree version. - -Fri Dec 17 12:09:11 1999 Greg J. Badros <gjb@cs.washington.edu> - - * tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the - SCM_NIMP test integrated into an || clause that I'd missed before - and was causing a segfault in the regression tests. - - * symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not - (char *); fixes a problem reported by the regression test - ports.test. - - * ports.c: Fixed a couple of arg/number mismatches in - SCM_VALIDATE_ macros. - - Now passes the (not-comprehensive) guile-modules test-suite again! - -Thu Dec 16 12:41:22 1999 Greg J. Badros <gjb@cs.washington.edu> - - * coop-threads.c: Remove K&R function headers. - - * scm_validate.h: Added SCM_VALIDATE_THREAD. - - * *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given - that SCM_FOOP macros all now include SCM_NIMP in their expansion. - This simplifies lots of code, making it far more readable. - -Wed Dec 15 19:45:14 1999 Greg J. Badros <gjb@cs.washington.edu> - - * *.h: Use SCM_NIMP(X) && in all the FOOP macros. - - * *.[ch]: Use do { ... } while (0) idiom in macros that expanded - to a bare block. - -Tue Dec 14 10:53:14 1999 Greg J. Badros <gjb@cs.washington.edu> - - * snarf.h: Put SCM_PROC and SCM_PROC1 back in for - backward-compatibility of packages that use Guile. Internally - Guile should not use them, though. (Maybe enforce this with a new - -DBUILDING_GUILE compile-time flag?). - -Tue Dec 14 09:41:01 1999 Greg J. Badros <gjb@cs.washington.edu> - - * backtrace.c (scm_set_print_params_x): Renamed from - set_print_params_x. - - * guile-doc-snarf.in: Use guile-snarf.awk, not - guile-doc-snarf.awk. Pass the basename of $filename - - * load.h: Added prototypes for scm_sys_library_dir, - scm_sys_site_dir. - - * load.c (scm_sys_library_dir, scm_sys_site_dir): Added these - functions, and took out the old scm_library_dir, scm_site_dir, - scm_pkgdata_dir. Now the primitives are %package-data-dir - (already existed), %library-dir, and %site-dir. - - * debug.c: Use SCM_MISC_ERROR when possible instead of using - s_scm_* in a scm_misc_error() call. - - * Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk. Make - using guile-doc-snarf send stdout to $@ to create the .x file like - guile-snarf does. - - * guile-snarf.awk.in: Added. - - * guile-doc-snarf.awk.in: Removed (sorry to back out a recent - commit; if we're going to switch to guile-snarf I figure it makes - sense to get this right now-- I'd already had the change in my - working copy when the below commit happened). - -1999-12-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * guile-doc-snarf.awk: Removed. - - * guile-doc-snarf.awk.in: Added. - - * ports.c (s_scm_pt_member): Fixed validation. - - * guile-doc-snarf.in (filename): Use basename in order to strip - away path. - - * debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing - semicolon. - (scm_memcons, scm_memcons, mem_to_proc): Renamed function name - strings to new form. - - * backtrace.c (set_print_params_x): Fixed GUILE_PROC macro. - - * tags.h (SCM_UNBOUND): New iflag which is needed for some time to - mark the unboundness of a GOOPS slot. (Added now in order to - correct a oversight. Should probably be removed again and - replaced with SCM_UNDEFINED when the corresponding code in GOOPS - is rewritten.) - - * print.c (scm_isymnames): Added printed representation for - SCM_UNBOUND. - - * eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in - SCM_IM_SLOT_REF. - -Mon Dec 13 17:23:22 1999 Greg J. Badros <gjb@cs.washington.edu> - - * strings.c: Fixed mistaken default value in - scm_make_shared_substring; thanks Eric Moore! - -Mon Dec 13 16:29:13 1999 Greg J. Badros <gjb@cs.washington.edu> - - * guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored - replacement for docstrings. Fixes problem Ryan Yeske observed - with using mawk on his system. Thanks Ryan! - -Mon Dec 13 13:30:06 1999 Greg J. Badros <gjb@cs.washington.edu> - - * guile-doc-snarf.in: Do not echo to stdout since the output now - gets stuck directly in the files instead of redirected from - stdout. - - * guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan - Yeske. Use print instead of printf to prime the .x file since - AIX's cpp has problems with #include-ing empty files (according to - the old guile-snarf.in file). - -Sun Dec 12 19:39:00 1999 Greg J. Badros <gjb@cs.washington.edu> - - * Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC, - GUILE_PROC1. Build guile-procedures.txt, and add that file to - pkgdata_DATA. - - * load.c: Added `pkgdata-dir', `site-dir', `library-dir' - primitives. - - * guile-doc-snarf.awk: Drop trailing space when no arguments: - e.g., "(foo )" is now "(foo)". - - * *.c, alist.c: moved all the documentation for primitives from - guile-doc/ref/{appendices,posix,scheme}.texi into the source code. - This leaves about half of the primitives undocumented. Also, all - the markup is currently still texinfo. I don't have a problem - with texinfo per se, but the markup is not very descriptive or - accurate. - -Sun Dec 12 16:50:26 1999 Greg J. Badros <gjb@cs.washington.edu> - - * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off - SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for - argument mismatches (along with the FUNC_NAME macro checking) by a - static tool that runs directly over the .c files. - - * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The - docstring is still missing from the .doc file; it just gives the - name of the C function that gets called instead. - - * guile-doc-snarf.awk: Be sure to touch the output files to help - make out. Also handle SCM_REGISTER_PROC better, and change the - output format slightly. - -Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu> - - * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for - guile-doc-snarf script. - - * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc - extraction system. Builds foo.x, foo.doc from foo.{c,cc}. - There are dependencies between these files and snarf.h. This - replaces guile-snarf. - - * guile-snarf.in: Drop everything after $$$ for the new snarf.h - macros. This is obsoleted by guile-doc-snarf, but kept here for - now for good measure. - - * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to - bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating - .doc files to use guile-doc-snarf. Update the rule for creating - .x files to use guile-doc-snarf. - -Sun Dec 12 12:31:38 1999 Greg J. Badros <gjb@cs.washington.edu> - - * *.c: Finish replacing K&R style prototypes with ANSI C - prototypes. - - * eval.c: Make scm_m_mody's 3rd argument be a const char *, not a - char *. ANSI prototypes caught this. - - * strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions - that I missed. - - * scm_validate.h: Use SCM_BOOLP for validating bools. Do not - expand macros if SCM_DOCSTRING_SNARF. - -Sun Dec 12 11:23:22 1999 Greg J. Badros <gjb@cs.washington.edu> - - * *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T: - SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F: - SCM_BOOL_T). - -Sun Dec 12 11:08:51 1999 Greg J. Badros <gjb@cs.washington.edu> - - * boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here, - from scm_validate.h. - - * scm_validate.h: Moved above out into boolean.h, fix typo in - SCM_VALIDATE_NIM macro. - -Sun Dec 12 10:29:12 1999 Greg J. Badros <gjb@cs.washington.edu> - - * *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP - (none of the other validate macros have the trailing P). - -Sun Dec 12 10:07:29 1999 Greg J. Badros <gjb@cs.washington.edu> - - * scm_validate.h: Added the FSF copyright to the top. - - * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of - SCM_ASSERT w/ SCM_OUT_OF_RANGE. - -Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu> - - * Makefile.am: Added scm_validate.h to modinclude_HEADERS. - - * *.c: Pervasive software-engineering-motivated rewrite of - function headers and argument checking. Switched SCM_PROC, - SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names - later, but was useful to keep old versions around while migrate) - that has docstrings and argument lists embedded in the GUILE_PROC - macro invocations that expand into a function header. Use lots of - new SCM_VALIDATE_* macros to simplify error checking and reduce - tons of redundancy. This is very similar to what I did for Scwm. - - Note that none of the extraction of the docstrings, nor software - engineering checks of Scwm is yet added to Guile. I'll work on - that tomorrow, I expect. - - * chars.c: Added docstrings for the primitives defined in here. - - * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added - SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC - still remains for now. Changed naming convention for the s_foo - string name of the primitive to be s_scm_foo for ease of use with - the macro. - - * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify - argument checking through guile. Maybe some of these should be - folded into the header file for the types they check, but for now - it was easiest to just stick them all in one place. - -1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb) - - * smob.c (scm_smob_prehistory): initialize allocated smob - - * tags.h: new tag: scm_tc16_allocated - - * gc.c (scm_gc_for_newcell): set the car of the new cell - to scm_tc16_allocated - * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated - (scm_gc_mark): mark allocated cells. - -1999-12-09 Greg J. Badros <gjb@cs.washington.edu> - - * strports.h, strports.c (scm_eval_0str): Fix constness. Some - thanks to Dirk Hermann. - - * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch, - gh_eval_str_with_standard_handler, - gh_eval_str_with_stack_saving_handler): Fix constness. Some - thanks to Dirk Hermann. - - * gh_data.c (gh_str02scm): Fix constness. - - * gh.h: Fix constness of prototypes for the above. - - * vectors.c: Include "unif.h" to avoid a warning about missing - prototype for scm_uniform_element_size(). - -1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x): - Turned into primitive generics. - -1999-12-04 Gary Houston <ghouston@freewire.co.uk> - - * ports.c (scm_port_closed_p): new procedure, implements - "port-closed?" suggested by Bernard Urban. - ports.h: added prototype, removed the SCM_P macros. - -1999-11-30 Gary Houston <ghouston@freewire.co.uk> - - * unif.h: added some comments, removed the SCM_P macros. - -1999-11-29 Gary Houston <ghouston@freewire.co.uk> - - * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str - (thanks to Daniel Skarda). - -1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com> - - * gscm.c, gscm.h: Deleted. They were unused. - -1999-11-20 Gary Houston <ghouston@freewire.co.uk> - - * unif.c (scm_list_to_uniform_array): call - scm_dimensions_to_uniform_array with a third argument of - SCM_UNDEFINED instead of SCM_EOL. - -1999-11-19 Gary Houston <ghouston@freewire.co.uk> - - * the following changes allow guile to be built with the array - "module" omitted. some of this stuff is just tc7 type support, - which wouldn't be needed if uniform array types were converted - to smobs. - - * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless - HAVE_ARRAYS. - (scm_tag): don't check array types unless HAVE_ARRAYS. - - * sort.c (scm_restricted_vector_sort_x, scm_sorted_p): - remove the unused array types. - * (scm_stable_sort, scm_sort): don't support vectors if not - HAVE_ARRAYS. a bit excessive. - - * random.c (vector_scale, vector_sum_squares, - scm_random_solid_sphere_x, scm_random_hollow_sphere_x, - scm_random_normal_vector_x): don't define unless HAVE_ARRAYS. - - * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect, - gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect, - gh_uniform_vector_length, gh_uniform_vector_ref): - don't define unless HAVE_ARRAYS. - (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats, - gh_scm2doubles): - don't check vector types if not HAVE_ARRAYS. - - * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1), - gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of): - don't support the array types unless HAVE_ARRAYS is defined. - - * tags.h: make nine tc7 types conditional on HAVE_ARRAYS. - - * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is - defined (this should use read-hash-extend). - - * ramap.c, unif.c: don't check whether ARRAYS is defined. - - * vectors.c (scm_vector_set_length_x): moved here from unif.c. call - scm_uniform_element_size if HAVE_ARRAYS. - vectors.h: prototype too. - - * unif.c (scm_uniform_element_size): new procedure. - - * init.c (scm_boot_guile_1): don't call scm_init_ramap or - scm_init_unif unless HAVE_ARRAYS is defined. - - * __scm.h: don't define ARRAYS. - - * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c - moved here from libguile_la_SOURCES. - -1999-11-18 Gary Houston <ghouston@freewire.co.uk> - - * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new - functions for network data conversion. - - * numbers.c (scm_num2long, scm_num2longlong): - throw out-of-range instead of wrong-type-arg if appropriate. - (scm_iint2str): handle -2^31 correctly. - (scm_num2long): handle -2^31 bignum correctly. - (scm_num2long_long): rewrite the bigdig case: basically copied - from scm_num2long. - numbers.h: (SCM_BITSPERLONGLONG): deleted. - - * unif.c (rapr1): use sprintf instead of intprint for unsigned - longs: intprint can't cope with large values. - - * numbers.c (scm_num2ulong): check more consistently that the - input is not negative. if it is, throw out-of-range instead of - wrong-type-arg. - - * ramap.c (scm_array_fill_int): don't limit fill to INUM for - uvect, ivect or llvect. - Check that fill doesn't overflow short uniform array. - - * __scm.h: add another long to the definition of long_long and - ulong_long. - - * unif.c (scm_raprin1): use 'l' instead of "long_long" in the - print representation of llvect. read can't handle more than - one character. - (scm_dimensions_to_uniform_array): make "fill" an optional argument - instead of a rest argument. - - * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free -

- * net_db.c (scm_inet_aton): throw errors using the misc-error key - instead of system-error. inet_aton doesn't set errno. - system-error isn't right in gethost either, since it's throwing - the value of h_errno instead of errno. so: - (scm_host_not_found_key, scm_try_again_key, - scm_no_recovery_key, scm_no_data_key): new error keys. - (scm_resolv_error): new procedure, use the new keys. - (scm_gethost): call scm_resolv_error not scm_syserror_msg. -

use, in case it has a sin_len field and the OS doesn't like random - values (thanks to Bertrand Petit). - -1999-10-26 Mark Galassi <rosalia@lanl.gov> - - * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take - a const char * argument, upon suggestion from Lynn Winebarger. - -1999-10-26 Gary Houston <ghouston@freewire.co.uk> - - * strports.c (st_end_input): avoid dubious pointer arithmetic. - -1999-10-24 Gary Houston <ghouston@freewire.co.uk> - - * Move the responsibility for resetting port buffers from the - caller of the ptob seek procedure to the implementation. This - gives more control in general to the ptob seek: in particular the - change of 1999-10-20 can be made to work without breaking seek on - string ports. There's a comment in NEWS about upgrading port - types. - - * ports.c (scm_seek): don't reset the port buffers here. - - * fports.c (fport_seek): reset the buffers, except for the - 0 SEEK_CUR case. - - * strports.c (st_end_input): (bug fix): decrement pt->read_pos by - offset. check that it's not less than read_buf. - (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR - case and currently reading. - -1999-10-20 Gary Houston <ghouston@freewire.co.uk> - - * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0, - so that unread chars are not needlessly discarded. (thanks to - Roland Orre). - -1999-10-18 Gary Houston <ghouston@freewire.co.uk> - - * fports.c (scm_fdes_to_port): always set rw_random if the fdes is - random access. rw_active needs to be maintained even for single - directional ports, otherwise scm_seek and probably other things are - broken. (thanks to Roland Orre). - - * strports.c (scm_mkstrport): set rw_random to 1 unconditionally. - - * ports.c (scm_add_to_port_table): initialise rw_random to 0. - - * ports.h (scm_port): change the comments on rw_random and rw_active. - -1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> - - * ioext.c: Added #include "feature.h". - - These changes turns `delay' into a memoizing macro. This is - because it may be expanded before evaluation if it occurs at the - beginning of a body. (Thanks to Lauri Alanko.) - - * eval.c, eval.h (scm_sym_delay): New global symbol. - - * tags.h (SCM_IM_DELAY): New immediate symbol. - - * print.c (scm_isymnames): Printed representation. - - * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY. - (scm_m_delay): Turned into a memoizing macro. - - * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version. - -1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com> - - * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are - protected from GC while building the vector.

Four representations - for procedure-with-setters were considered before selecting this - one: - - 1. A closure where the CODE and ENV slots are used to represent - the getter and a new SETTER slot is used for the setter. The - original getter is stored as a `getter' procedure property. For - closure getters, the CODE and ENV slots contains a copy of the - getter's CODE and ENV slots. For subr getters, the CODE contains - a call to the subr. - - 2. A compiled closure with a call to the getter in the cclo - procedure. The getter and setter are stored in slots 1 and 2. - - 3. An entity (i.e. a struct with an associated procedure) with a - call to the getter in the entity procedure and the setter stored - in slot 0. The original getter is stored in slot 1. - - 4. A new primitive procedure type supported in the evaluator. The - getter and setter are stored in a GETTER and SETTER slot. A call - to this procedure type results in a retrieval of the getter and a - jump back to the correct eval dispatcher. - - Representation 4 was selected because of efficiency and - simplicity. - - Rep 1 has the advantage that there is zero penalty for closure - getters, but primitive getters will get considerable overhead - because the procedure-with-getter will be a closure which calls - the getter. - - Rep 3 has the advantage that a GOOPS accessor can be a subclass of - <procedure-with-setter>, but together with rep 2 it suffers from a - three level dispatch for non-GOOPS getters: - - cclo/struct --> dispatch proc --> getter - - This is because the dispatch procedure must take an extra initial - argument (cclo for rep 2, struct for rep 3). - - Rep 4 has the single disadvantage that it uses up one tc7 type - code, but the plan for uniform vectors will very likely free tc7 - codes, so this is probably no big problem. Also note that the - GETTER and SETTER slots can live directly on the heap, using the - new four-word cells. - - * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER, - SCM_SETTER): New macros. - (scm_procedure_with_setter_p, scm_make_procedure_with_setter, - scm_getter, scm_setter): New procedures. - - * eval.c, print.c (scm_iprin1): Added entries for scm_tc7_pws. - - * gc.c (scm_gc_mark, scm_gc_sweep): Added case labels for - scm_tc7_pws. - - * objects.c, objects.h (scm_class_of, - scm_class_procedure_with_setter): Added. - - * procprop.c (scm_i_procedure_arity), procs.c (scm_thunk_p): Added - entry for scm_tc7_pws. - - * procs.c (scm_procedure_p): Added case label for scm_tc7_pws. - -1999-01-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * evalext.c, evalext.h (scm_m_generalized_set_x): New memoizing - macro. - (scm_init_evalext): Call scm_make_gsubr for - scm_m_generalized_set_x. - - * eval.c, debug.c, tags.h (SCM_IM_SET_X): Renamed from SCM_IM_SET. - - * eval.h: Declare scm_s_set_x, scm_sym_set_x; - - * eval.c: Renamed "set" --> "set_x" in various names for - consistency of name correspondence between Scheme and C; - Renamed scm_i_set_x --> scm_sym_set_x and made global. - Renamed s_set_x --> scm_s_set_x and made global. - -1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * random.c (scm_i_random_bignum): Made independent of endianness. - -1999-01-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * eval.c (SCM_CEVAL): Added ENTER_APPLY in code for SCM_IM_APPLY. - (Thanks to Eric Hanchrow.) - -1999-01-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * objects.c, objects.h (SCM_CLASS_REDEF): Renamed from CLASS_REDEF. - - * random.c: Bugfix: Retrieve and store most significant 32 bits in - different order if the machine is bigendian. - (scm_init_random): Added safety check for bignum digit size. - -1999-01-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se> - - * random.c, random.h (scm_i_make_rstate): New function: Makes - scm_rstate from seed. - (scm_copy_random_state, scm_seed_to_random_state): New functions. - (scm_make_random_state): Removed. - - * random.c (scm_make_random_state): Use scm_i_make_rstate(). - -1999-01-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * random.c: Bugfix: Retrieve and store most significant 32 bits in - different order if the machine is bigendian. - (scm_init_random): Added safety check for bignum digit size. - -1999-01-11 Roland Orre <mdj@mdj.nada.kth.se> - - * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements - from first arg before equal elements in second arg in result. - (scm_merge_list_step): Bugfix: Don't presume that arguments in a C - function call are executed in a well defined order. - -1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com> - - * alloca.c (alloca): Cast value returned by malloc.

Contain non-R5RS things - having to do with evaluation. - - * evalext.c (scm_serial_map): New procedure: Version of `map' - which guarantees that the procedure is applied to the lists in - serial order. - (scm_m_sequence_to_list): New syntax: Version of `begin' which - returns a list of the results of the body forms instead of the - result of the last body form. - (scm_definedp, scm_m_undefine): Moved from eval.c - - * evalext.h (scm_m_sequence_to_list): Added declaration. - - * macros.c, macros.h: New files. - (scm_procedure_to_syntax, scm_procedure_to_macro, - scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type, - scm_macro_name, scm_macro_transformer): Moved from eval.c - (scm_make_synt): Moved from eval.c - - * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c. - - * init.c (scm_boot_guile_1): Added calls to scm_init_macros and - scm_init_evalext. - - * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h. - - * debug.c, print.c: Added #include "macros.h". - -1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se> - - This change adds the ability to use `unread-char' multiple times - without interspersed reads and adds the new procedure - `unread-string'. The change is optimized for the common case of - unreading a single character. This is also the reason behind the - choice to store characters in the port itself: in most cases no - extra malloc is required. - - The amount of code in some macros in ports.h has been increased to - the extent that they would fit better as C functions, but, since - this code belongs to the port representation, such functions - should be placed in ports.c which would cause calls back and forth - between ports.c and genio.c. That is not good for performance. - Also, keeping them as macros allows the compiler to do some - optimizations which are needed to make the current interface - (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient. - - One benchmark (Guile startup time) indicates an increase of - loading speed of 1%. Another (reading (using `read') boot-9.scm - 10 times) shows no change in performance. - - (Caveat: Since Gary is redesigning I/O anyway, no big efforts were - made to find a beautiful solution.) - - * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten. - (SCM_TRY_CLRDY): New macro: Only clear the first unread - character. (SCM_CLRDY clears all.) - (SCM_N_READY_CHARS): New macro: Returns number of unread - characters in a port. Returns wrong answer if SCM_CRDYP is false. - (struct scm_port_table): New fields: `entry' contains port table - index, `cp' points to last unread char, `cbuf' is the buffer for - unread chars, `cbufend' points after end of the character buffer. - - * ports.h, ports.c (scm_unread_string): New procedure. - (scm_grow_port_cbuf): New function. - - * ports.c (scm_add_to_port_table, scm_remove_from_port_table): - Handle new fields. - (scm_generic_fgets), fports.c (local_fgets): Use a loop - to read unread characters. Use SCM_TRY_CLRDY instead of - SCM_CLRDY. - - * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position. - - * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY. - - * genio.c, genio.h (scm_ungets): New function. - - * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code - sections. - -1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed - declarations. (Thanks to Russ McManus.) - -1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se> - - * numbers.c (num2long): As a software archeologist, I'm proud of - this finding! :) Preliminary dating suggests an almost 4 year old - remnant from the SCM ancestor. The sample has been removed from - the finding site and is now safely stored in the repository. - - * numbers.h: Removed prototype for num2long. - - * unif.c (scm_array_set_x): Use scm_num2long instead of num2long. - - * gh_data.c (gh_scm2doubles): Make it possible to pass result - array as second arg. - (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars, - gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions. - * gh.h: Updated and added prototypes. - - * gh_data.c (gh_ints2scm): Handle integers outside INUM limits. - -1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com> - - * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.) - - * guile-snarf.in: Never generate an empty file.

(Thanks to Brad Bowman.) - - Bug reports from Russ McManus: - * guile-snarf.in: If the CPP environment variable is set, use that - as the C preprocessor, instead of the preprocessor autoconf - found. - * snarf.h (SCM_PROC): Cast the function pointer passed to - scm_make_gsubr, to satisfy C++. - - * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch): - Use the handler passed, instead of ignoring it and using - gh_standard_handler.

This may seem nutty, but, like the other - uniform vectors, byte vectors and short vectors want to have the - same print and read syntax (and, more basic, want to have read - syntax!). Changing the read syntax to use multiple characters - after the hash sign breaks with the conventions used in R5RS and - the conventions used for the other uniform vectors.

Now both - libguile/versiondat.h and ice-9/version.scm are generated directly - by the configuration process, rather than having version.scm - generated directly, and libguile/versiondat.h generated by the - Makefile, which is generated by configure. It seems that - sometimes the Makefile would change, but versiondat.h depends on - Makefile.in, not Makefile, so it wouldn't get rebuilt. - * Makefile.am (versiondat.h): Target removed; this is generated - directly by the configure script now. - (BUILT_SOURCES): Remove versiondat.h. - * versiondat.h.in: New file, transformed by the configure script - into versiondat.h. - * Makefile.in: Regenerated. - - * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c, - options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS -> - SCM_CAUTIOUS; this way, 1) there's only one version of each flag - to define (we used to have both RECKLESS and SCM_RECKLESS), and 2) - if we want to use them in a header file some day, we can. (Thanks - to Michael Livshin.) - - * stime.c (scm_get_internal_real_time): Do the arithmetic using - SCM numbers, so we won't have rollover problems; the range of a - signed long in milliseconds is about 25 days. (Thanks to Karl - Hegbloom.) - - Don't redefine sleep and usleep; fix this problem now. - * coop.c (sleep, usleep): Remove declarations; we don't use or - redefine these any more. - (scm_thread_usleep, scm_thread_sleep): New functions which do the - job of usleep and sleep in a thread-friendly way. We can use - these in the rest of Guile. Define versions for systems both with - and without iselect. - * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations. - * scmsigs.c (usleep): Clean up oddities declaring usleep; since - we're just using it, not redefining it, we can use a K&R style - declaration here. - (sleep): Declare this, too, if the system hasn't. - (scm_sleep, scm_usleep): Use scm_thread_sleep and - scm_uthread_sleep if they're available; otherwise, just call the - system functions. - * scmconfig.h.in: Regenerated. - - * coop.c (scm_thread_sleep): Make `slept' an unsigned long. - - * coop.c (coop_sleephelp): Remove ANSI #ifdef hair. - -1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com> - - * threads.c: Doc fix. - - The argument type of usleep varies from system to system, - as does the return type. We really shouldn't be redefining usleep - at all, but I don't have time to clean that up before the 1.3. - release. It's on the schedule for afterwards. (Thanks to Julian - Satchell.) - * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and - definition. - * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype. - * scmconfig.h: Regenerated. - - * simpos.c (scm_software_type): Procedure deleted. This isn't the - right way to handle system variation. Autoconf's approach is the - way and the light. - * simpos.h (scm_software_type): Declaration deleted. - - * script.c (scm_find_executable): Don't test if unix is #defined - here; first, NetBSD doesn't #define it, and second, it's the wrong - way to go about these things. (Thanks to Perry Metzger.) - (dld_find_executable): Delete this MSDOS support code. This isn't - the way we want to support this; it needs to be rethunk at a - larger scale. - - * genio.c (scm_do_read_line): Don't just politely check that the - line was either non-empty or EOF. Abort if it's empty and not - EOF. - -1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com> - - * scmconfig.h.in: Regenerated. - - * libguile.h: Don't omit the dynamic linking functions. (Thanks - to Greg Badros.) - - * genio.c (scm_do_read_line): Count lines correctly when the file - doesn't end in a newline. - -1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com> - - * genio.c (scm_do_read_line): Maintain the line count correctly. - (Thanks to Harvey J. Stein and Greg Harvey.) - - * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile - requires ANSI now. - - * numbers.c (big2str): Protect t from garbage collection until - we're done. (Thanks to Gary Houston.) - -1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com> - - * Makefile.am (libguile_la_LDFLAGS): Increment shared library - version number. - * Makefile.in: Regenerated. - - * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno, - scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of - SCM_P macro. - - Do magic to mix reads and writes on stdio FILE-based ports. - (Thanks to Christian Lynbech.) - * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY): - New macros. - (pre_read, pre_write): New functions. - (local_fgetc, local_fgets, local_ffwrite, local_fputc, - local_fputs): Call them. - (local_fflush): Mark the port as ready for reading and writing. - (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE - flags on new port objects. This might not be accurate --- who - knows what state the FILE * is in when we get it --- but it won't - do extraneous calls to fflush or fseek, so it's no worse than the - behavior before this change. - * ports.h: Add comment. - - Centralize the creation of port objects based on stdio FILE * in - fports.c; don't just throw them together anywhere. - * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is - what the rest of Guile wants. Don't set the revealed count; - that's only appropriate for stdin, stdout, stderr. - (scm_standard_stream_to_port): This function does set the revealed - count. - * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port, - not scm_stdio_to_port. - * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out. - * fports.c (scm_open_file): Same. - * posix.c (scm_pipe): Same. - * socket.c (scm_sock_fd_to_port): Same. - * ioext.c (scm_fdopen): Same. - (scm_freopen): Moved from here to... - * fports.c (scm_freopen): ... here. This is really something that - munges the internals of an fport, so it should go here. - * fports.h (scm_stdio_to_port): Adjust prototype. - (scm_standard_stream_to_port, scm_freopen): New protoypes. - * ioext.h (scm_freopen): Prototype removed. - - * filesys.c (set_element, get_element): This can work on both pipe - and file ports, so use SCM_FPORTP to typecheck, instead of testing - for scm_tc16_fport. - - * scmconfig.h.in: Regenerated. - - Change the definition of the functions in scm_ptobfuns so that - they get passed the port object, not the port's stream. - * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'. - * gc.c (scm_gc_sweep): Pass the port itself to the free function. - * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc): - Pass the port itself to the scm_ptobs function. - * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports, - scm_generic_fgets): Same. - (putc_void_port, puts_void_port, write_void_port, flush_void_port, - getc_void_port, fgets_void_port, close_void_port): Just change the - argument names; these functions don't really do anything. - * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush, - local_fputc, local_fputs, local_ffwrite, local_pclose): Take the - port as an argument, and use SCM_STREAM to get the stdio FILE *. - Also, use prototyped definitions, and get rid of the extra - declarations. - (scm_fptob, scm_pipob): We don't need casts here any more. - * strports.c (prinstpt): Use prototype declarations. - (stputc, stwrite, stputs, stgetc): Take the port as an argument, - and use SCM_STREAM to get the string info. Also, use prototyped - definitions, and get rid of the extra declarations. - * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose, - noop0): Same. - - * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight - prototype; it's okay (preferred, even!) to use ANSI C in Guile. - - * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and - scm_fgets, for consistency. - (scm_fptop, scm_pipob): References updated. - -1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com> - - Include the source location in error messages for scripts. - * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the - stack is still there when we catch the error. - * throw.c (handler_message): If we are handling an error with a - message, then put together the proper arguments and call - scm_display_error, instead of scm_display_error_message. That - displays source location, if it can find it. - -1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com> - - * gc.c (scm_unprotect_object): Change this so that calls to - scm_protect_object and scm_unprotect_object nest properly. - (scm_protect_object): Doc fixes. - - * strings.c (scm_string_set_x): Require the argument to be a - writable string, not a substring or a symbol. - * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates. - (Thanks to John Redford and Charbel Jacquin.) - - * scmconfig.h.in: Regenerated; ../acconfig.h has changed. - -1998-10-07 Jim Blandy <jimb@totoro.red-bean.com> - - * eval.c (safe_setjmp): Remove this misunderstanding. - (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to - ordinary setjmp. - -1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com> - - * libguile.h: Mark these as C declarations, for compilation by C++ - compilers. - - * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef - __cplusplus clause. I seriously doubt this ever worked the way - the author seems to have intended. - -1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com> - - Utterly needless cleanups to hopelessly messy code. - * ports.c: Doc fixes. - (scm_fflush): Moved to ... - * genio.c (scm_fflush): ... here, amongst all the other port - method invocation functions. - * genio.h, ports.h: The prototype moves too. - -1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com> - - * backtrace.c (display_error_body): The current frame does not - always have a parent frame; consider a function called directly - from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej - Stachowiak.) - - * alloca.c (alloca): Undo yesterday's changes, and simply call - malloc directly for storage, and abort if we don't get what we - want. The situation is much simpler --- just call malloc. Emacs - has bizarre/evil requirements (signal handlers might malloc unless - you set this global flag, so you have to set the flag around all - calls to malloc) which we are certainly not going to conform to, - so we can do the simple and obvious thing. - - * coop.c (coop_condition_variable_wait): Make this function - static. It's only useful internally --- you should never just - wait on a condition variable. - * coop-defs.h (coop_condition_variable_wait): Delete prototype. - -1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com> - - * unif.c (scm_array_set_x): Accept any kind of number as an - element for a uniform vector of doubles. This is more consistent - with Scheme's view of numbers. (Thanks to Miroslav Silovic.) - - * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this - works; I can't conveniently test it myself. (Thanks to Dvid - Tillman for the bug report.) - - * init.c: Doc fixes. - - * init.c (invoke_main_func): Load the startup files (boot-9.scm) - from here, not from scm_compile_shell_switches (which is a pretty - dumb place to do it). - (scm_load_startup_files): New function. - (scm_ice_9_already_loaded): Variable moved to here from script.c. - * script.c (scm_compile_shell_switches): Don't load the startup - files here. - (scm_ice_9_already_loaded): Variable moved. - * init.c (scm_load_startup_files): Prototype for new function. - * gh_init.c (gh_enter): Doc fix. - -1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com> - - Some anti-warning changes from Greg Harvey. - * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler - warnings when it doesn't understand our NORETURN declarations in - error.h. - * posix.c (scm_mknod): Similar. - -1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com> - - * posix.c (scm_getpwuid): If we can't find an entry, return our - own message, instead of using scm_syserror --- the getpwMUMBLE - functions don't set `errno' to anything interesting. - -1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com> - - Get rid of warnings from the cooperative threading system. - * threads.h (scm_single_thread_p, scm_yield, - scm_call_with_new_thread, scm_join_thread, scm_make_mutex, - scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable, - scm_wait_condition_variable, scm_signal_condition_variable): Add - prototypes for these Scheme-visible functions. - * coop-defs.h (coop_next_runnable_thread, - coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread): - Prototypes for these here, even though they're from iselect.c. - (coop_condition_variable_wait, coop_join): Add prototypes. - * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex, - scm_threads_free_condvar): Make these smob functions static. - * coop-threads.h (coop_init): Give this a real prototype. - * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'. - (coop_next_runnable_thread): No need to provide prototype; it's in - coop-defs.h. - - * scmconfig.h.in: .detarenegeR - - * iselect.c, threads.c: Doc fixes. - -1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com> - - * Makefile.in: Regenerated with a patched automake, to get - dependency generation right when using EGCS. - - * inet_aton.c (inet_aton): Add prototype, to remove compiler - warning.

This - kludge overrides the test if we're on totoro so that the snapshot - generation process can work. - - * readline.c: Define a strdup replacement if not existent on system. - -1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se> - - * vectors.c, vectors.h (scm_make_vector): Removed third argument. - This change makes scm_make_vector R5RS compatible. We cannot keep - the third argument since people want to be able to deduce the form - of the C function call only by looking at R5RS. (At the same time - we have removed some unnecessary complexity!) - - * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c, - net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c, - stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third - argument in call to scm_make_vector. - -1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP. - This macro is useful in applications. - -1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se> - - * load.c (scm_internal_parse_path): Renamed from scm_parse_path. - (scm_parse_path, scm_search_path): New Scheme level procedures. - - * load.h (scm_internal_parse_path, scm_parse_path, - scm_search_path): Declared. - -1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * filesys.c (dirname, basename): New procedures. - - * init.c (scm_boot_guile_1): Removed condition around - scm_init_options. - - * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a - new data type (guards) for representation of C level guards and - data on the wind chain. - (scm_internal_dynamic_wind): New function. - - * dynwind.h: Declare scm_internal_dynamic_wind. - - * root.h (scm_root_state): Added scm_cur_loadp. - - * root.c (mark_root): Added comment about cur_loadp. - - * load.c: #include "dynwind.h"; - (scm_primitive_load): Use scm_inner_dynamic_wind to update - scm_cur_loadp. - - * init.c (scm_init_standard_ports): Initialize scm_def_loadp. - - * ports.c (current-load-port): New procedure. - -1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * ioext.c (scm_isatty_p): Accept any kind of data as argument. If - not a tty, return #f. - - * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks - to Julian Satchell and Roland Kaufmann.) - - * gh.h (gh_memv, gh_member): Fixed typos in macro definitions. - (gh_write): Added declaration. (Thanks to Eiichi Takamori.) - -1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se> - - * debug.h, debug.c (scm_start_stack): New function. Implements - the guts of old scm_m_start_stack. - - * debug.c (scm_m_start_stack): Use scm_start_stack. - - * init.c (scm_start_stack, scm_restart_stack): Renamed to - start_stack and restart_stack. (These have static scope.) - -1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * readline.c (rl_cleanup_after_signals, rl_free_line_state): New - readline functions to come in release 2.3. (Thanks to Chet - Ramey.) - (handle_errors): Use the above functions. - -1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * readline.c: Improvements for readline support: Handle errors - better; Implement before-read-hook. - -1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * init.c (scm_boot_guile_1), readline.c: Test for - HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to - assure that we have version >= 2.1.) - -1998-05-11 Mikael Djurfeldt <mdj@kenneth> - - * readline.c (scm_readline): Defer interrupts while we're calling - readline. - - * readline.c (scm_add_history): Bugfix: Do strdup before giving - away the string to add_history. - (completion_function): Do completion for readline. (Thanks to - Andrew Archibald.) - (scm_filename_completion_function): New procedure: Filename - completer. - (current_input_getc): New function. Use this one instead of - standard getc from readline. - - * throw.c, throw.h (scm_handle_by_throw): New function: This - handler throws errors to next handler on the dynwind chain. - -1998-05-09 Mikael Djurfeldt <mdj@kenneth> - - * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't - used. - -1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * procprop.c (scm_i_procedure_arity): New function. Returns arity - of procedure. - (scm_procedure_properties): Modified to return arity together with - other properties. - (scm_procedure_property): Added the read-only property `arity'. - (scm_set_procedure_property_x): It is an error to set the `arity' - property. - - * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added - prefix SCM_; Made f_gsubr_apply global and added prefix scm_. - - * procprop.h (scm_sym_arity): New symbol. - - * objects.c (scm_set_object_procedure_x): New procedure: Use this - to set the dispatch procedure of an operator or entity object. - - * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT): - Made procedure slots read-only. - - * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above - scm_tcs_cons_gloc case in zero args switch; Fixed args - construction for operators in scm_tcs_cons_gloc case in two args - switch. - -1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * fluids.c: Removed use of assert.h (in order to avoid - __eprintf). - - * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic. - - * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0. - - * eval.c (SCM_CEVAL): Do more thorough argument checking. This - change makes the evaluator safer at the cost of evaluation speed. - It handles the case when the user has added a non-immediate - improper end of the application form, e.g., `(+ 0 . x)'. - (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to - minimize the extra cost as much as possible. The new code is - enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the - problem with structs planted directly in the code (e.g. by a - macro). This no longer causes segmentation fault. (Thanks to - Eric Hanchrow.) - - * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra - arg `proc' in order to be able to throw errors; New argument - checking code. - - * Removed extra #include "debug.h" - -1998-04-25 Mikael Djurfeldt <mdj@kenneth> - - * scmsigs.c: Declare usleep as returning void on some systems. - (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian - Satchell.) - - * coop.c (usleep): Return void on some systems. - -1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath. - - * coop.c: Changed return type of usleep to int. - - * scmsigs.c (scm_usleep): New procedure; Declare usleep if it - isn't found in the OS. - - * iselect.h: #define scm_internal_select select if GUILE_ISELECT - isn't enabled. (Thought that I had made this change ages ago...) - - * iselect.c: Declare bzero if not defined by OS. - -1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * dynl.c (scm_must_free_argv): Fixed memory leak due to negated - condition. (Thanks to John Tobey.) - - * continuations.c (scm_make_cont), debug.c (scm_make_memoized, - scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS --> - A section. - - * __scm.h: Start the long-term project of moving to POSIX threads. - Phase 1: Classification of all critical sections. - (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters - for A sections. (See comments in __scm.h for details.) - - * dynl.c: Only check that HAVE_DLOPEN is defined before loading - dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD. - -1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c, - cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES - (libpath.h, versiondat.h): Replaced dependency on Makefile with - dependencies on $(srcdir)/Makefile.in - $(top_builddir)/config.status in order to avoid circularity. - - * script.c (scm_compile_shell_switches): Bugfix: Don't discount i - from argc if argc was 0 initially. - - * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS - in generation of libpath.h. - -1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se> - - * Makefile.am (libguile_la_LDFLAGS): Bumped version number of - libguile from 2 to 3. - -1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se> - - * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES. - -1998-04-13 Mikael Djurfeldt <mdj@kenneth> - - * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column, - scm_set_port_column_x, scm_port_filename, - scm_set_port_filename_x): Removed optional arguments. Added - proper argument checking. - - * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure - stack size in machine words. - - * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x, - rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks - to Ole Myren Röhne.) - -1998-04-12 Mikael Djurfeldt <mdj@kenneth> - - * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of - UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.) - - * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben - Caradoc-Davies.) - - * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the - procedure apply: Copy argument lists before pushing them unto the - environment so that the environment won't get mutated due to - manipulation of procedure arguments. This should perhaps be - regarded as a temporary solution until someone finds a more - efficient one. (Thanks to Maciej Stachowiak.) - -1998-04-10 Mikael Djurfeldt <mdj@kenneth> - - * script.c (scm_compile_shell_switches): Use "guile" as default - zero arg if argc is NULL. - -1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se> - - * script.c (scm_compile_shell_switches): Allow NULL argv if argc - is zero. (Thanks to Dirk Herrmann.) - -1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se> - - * ports.c (scm_add_to_port_table): First line is now line 0 - (was 1). (Interface changed according to suggestion by Per - Bothner.) - - * backtrace.c (display_header): Add 1 to line and column numbers - when presenting them to the user. - - * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved - from debug.c --> eval.c - - * eval.h, eval.c (scm_eval_options_interface): New options - interface. - (SCM_EVAL_STACK): New option: Size of newly created stacks, - i.e. stacks for new threads. - - * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK. - - * eval.c (unsafe_setjmp): Removed with #if 0. - - * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler - warning. - - * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces - to avoid compiler warnings. - - * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed. - -1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se> - - * throw.c (handler_message): Print message on current error port - instead of default error port. (Thanks to Maciej Stachowiak.) - -Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz> - - * ports.c (scm_add_to_port_table): allocate in units of - struct scm_port_table *, not struct scm_port_table. - * posix.c (scm_close_pipe): remove the port from the port table - and mark as closed. - Thanks to Rob Engle for both fixes. - -1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h, - coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998. - -1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * throw.h: Removed jmpbuf arg in scm_catch_body_t. - - * backtrace.c (display_error_body, display_backtrace_body), - coop-threads.c (scheme_body_bootstrip, c_body_bootstrip), - gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c - (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body, - scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body - functions. - - * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies - don't receive the jmpbuf arg anylonger. - (scm_catch): Don't accept a #f tag. - (scm_throw): Check that key is a symbol. - (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg. - -Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth> - - * async.c (async_pending): Removed declaration. - -1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * dynwind.c (scm_wind_chain): New debug function. - - * coop-threads.c (scheme_launch_data, scheme_body_bootstrip, - scheme_handler_bootstrip, scheme_launch_thread, c_launch_data, - c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an - extra layer of functions around the body and handler of a thread. - This extra layer makes sure that the handler is called in the - dynamic context of the surround (= empty dynwind list), but under - the *dynamic root* of the body. We can not use the dynamic root - of the surround since that root belongs to another thread => stack - is not handled correctly. It may seem ugly to use this extra - layer, but the extra cost in terms of execution time is really - negligible compared to the total amount of time required to create - a thread, and it would reduce maintainability to duplicate the - crucial and complicated steps performed by cwdr. - - * __scm.h (SCM_ASYNC_TICK): Removed thread switching code. - (SCM_ALLOW_INTS): Added thread switching code before interrupts - get re-enabled. The important effect of this is that interrupts - are blocked during thread switching so that thread data structures - don't risk getting messed up by an unfortunate signal. - (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0 - seems to do more aggressive optimization which actually move - instructions around in these macros in a fatal way. Therefore: - Introduce Anthony's SCM_FENCE macro! (And I who thought he was - just superstitious...) - (SCM_TICK): Maybe do a context switch and take care of asyncs. - This macro should be used instead of SCM_ASYNC_TICK since the - latter doesn't do context switches any more. - - * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK - instead of SCM_ASYNC_TICK. - - * coop.c, iselect.c: Since thread switches are now performed with - interrupts masked, we can't use the old mechanism of delivering - signals immediately when they arrive. Signals must instead be - delivered when the asyncs run *after* the end of the critical - section in scm_internal_select. But this also means after context - switch so that the signal will be delivered to a different thread. - To avoid this, I have changed the protocol of - coop_wait_for_runnable_thread and friends so that they are allowed - to return the original thread. So, if a signal arrives during - scm_internal_select, we won't any longer be forced do a context - switch, but can remain in the same thread and deliver the signal - to it. - - * async.c, async.h (asyncs_pending): Renamed asyncs_pending --> - scm_asyncs_pending and made it global. - - * iselect.c: Small fixes. - - * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock, - coop_condition_variable_init, coop_condition_variable_wait, - coop_condition_variable_signal): Changed return type from `void' - to `int'. This is to adhere closer to the pthreads interface. - This, in turn, is part of an attempt to provide C versions of the - mutex and condition variable primitives which can be part of a - frontend to COOP or pthreads. - - * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex, - coop_condition_variable_destroy): New functions. - - * coop-threads.c (scm_wait_condition_variable): Use - coop_condition_variable_wait_mutex. - - * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c): - Definitions moved to coop-defs.h. - - * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock, - scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal, - scm_cond_destroy): New C interface to mutecis and cond vars. - -1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7. - - * iselect.c: Now several threads can wait on the same file - descriptor. The behaviour is compatible with OS select: All - threads waiting for the fd return with the same status. - -1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * coop-threads.c, threads.h (scm_spawn_thread): New function. - Can spawn a thread from application C code. - -1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect, - gh_doubles2scm): New functions. - -1998-01-15 Mark Galassi <rosalia@nis.lanl.gov> - - * gh_eval.c (gh_eval_str): cleanup -- threw out the old - commented-out version of gh_eval_str() - -Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz> - - * socket.c (scm_bind): free soka after use. - -Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz> - - * stime.c (tzvar): new variable. - (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime): - avoid memory leaks when allocating. - -1998-01-03 Jim Blandy <jimb@totoro.red-bean.com> - - * iselect.h: Some systems require <sys/types.h> to get the FD_SET - macro definitions. - - * gc.c, tags.h: Doc fixes. - -1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * eval.c (macro-eval!): Removed. This function was a design bug. - It allowed memoized code to leak out to the scheme level. Most - things that you could do with `macro-eval!' can be done with - `local-eval'. - -1997-12-20 Tim Pierce <twp@skepsis.com> - - * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since - scm_fgets now depends on ftell(3) to know how many bytes were - read. Sigh. - -1997-12-15 Tim Pierce <twp@skepsis.com> - - * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for - dealing with strings. - -1997-12-13 Tim Pierce <twp@skepsis.com> - - Make %read-line more suitable for implementing read-line efficiently. - * ioext.c (scm_read_line): Strip the terminating newline from a - string, and return a cons of the string and its terminator. - - * fports.c, fports.h (scm_fgets): Add `len' argument. The length - of the string that is read is stored in this memory location. - * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same. - * genio.c, genio.h (scm_do_read_line): Update caller. - * ports.h (scm_ptobfuns): Update typedef. - * fports.c (scm_fptob, scm_pipob): Update struct. - -1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * filesys.c (set_element): Return file descriptor. - (fill_select_type): Return the highest file descriptor. - (scm_select): Tell select about the highest file descriptor. On - some systems the SELECT_SET_SIZE can be as much as 128 bytes. - Therefore the extra overhead for calculating the maximum fd seems - to be more than compensated. Is this correct? In any case, - scm_internal_select will be much faster with this info. - (scm_select, fill_select_type, set_element): Don't accept any kind - of object in the file descriptor list or vector. - -1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * iselect.c (finalize_fd_sets): Bugfix. - -1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS - when using scm_internal_select (since we might switch to another - thread). - -Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz> - - * simpos.c (scm_system): always define: use sysmissing if not - available. Check for HAVE_SYSTEM instead of _Windows (does - Windows lack system or does it have an unusable one?). - Check for error conditions -1 and 127. Use SCM_DEFER_INTS. - Let the argument be optional: if not supplied, call system(NULL). - - * ports.c (scm_close_port): relax the type check from OPPORTP to - PORTP; closing a closed port is allowed. - -1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net> - - * fports.c (scm_fgets): Return if the last char in a chunk is - newline. When fgets returns a string whose length is `size-1', it - is ambiguous whether a whole line was retrieved, so we must check - explicitly whether a line terminator is present. - -1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair - before taking the CDR.

Add a 'direction' argument - to indicate what way the search should go. - (scm_i_index): throw out-of-range error instead of wrong-type-arg - if indices are bad. - (scm_string_index, scm_string_rindex): adjust usage of scm_i_index. - strop.h: remove scm_i_index, scm_i_rindex prototypes. - -Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz> - - * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names. - - * posix.c (scm_fork): Scheme name changed from fork to primitive-fork, - to avoid clash with various scsh forks. - -Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se> - - The following two changes (ramap.c, throw.c) are motivated by the - apparent unportability of forward declarations of static arrays of - the form `static foo bar[];'. - - * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int. - (ra_rpsubrs, ra_asubrs): Moved to the top of array code. - - * throw.c (scm_throw): Moved above scm_ithrow. - - * options.h: Removed the extern declarations of scm_yes_sym and - scm_no_sym since these are static. - -Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz> - - * ports.c: add SCM_PROC declarations for pt-size and pt-member. - - * Makefile.am: remove AWK=@AWK@. - Add a rule for generating errnos.list. - (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES. - - * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT). - don't extract errnos, just set a variable (avoids the - need to recompile error.c just because configure is run.) - - * unif.h: update prototypes. - * unif.c (scm_uniform_array_read,write): change the offset and - length arguments to start and end, for consistency. - - * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6. - - * ioext.h: update prototypes. - * ioext.c (scm_read_delimited_x): replaces scm_read_line and - scm_read_line_x, it's a more general procedure using an - interface from scsh. read-line and read-line! are now defined - in boot-9.scm. - Note that the new read-line trims the terminator - by default, previously it was appended to the returned string. An - optional argument specifies how to process the terminator (scsh - compatible). For the old behaviour: (read-line port 'concat). - scm_read_line, scm_read_line_x: deleted. (read-line port 'split) - returns a pair, but is converted to multiple values if the scsh - module is loaded. - - socket.h: update prototypes. - * socket.c (scm_recvfrom): for consistency with other procedures, - take start and end as separate optional arguments. - (scm_recv, scm_recvfrom): don't allow the second argument - to be a size, only a buffer.

Don't return the buffer. - - * ioext.h, posix.h: move prototypes too. - * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line: - moved back from posix.c to ioext.c. Also move #includes of "genio.h" - "read.h" and "unif.h". - * ioext.c: include "chars.h" - -Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de> - - * dynl.c: The dynamic linking and module registration functions - are now defined even when dynamic linking is not available for the - host system.

It uses the current toplevel lookup closure to give - the symbol its value. This is a temporary hack to put packages - like gtcltk into their own module. - (scm_can_use_top_level_lookup_closure_var): New variable to tell - us whether `scm_top_level_lookup_closure_var' has been initialized - and is usable. - * eval.c (scm_init_eval): Set it. - -Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz> - - * fports.c (scm_open_file): pass errno to scm_syserror_msg. - * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS, - SCM_FD. - * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to - scm_syserror_msg. - (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek, - scm_sys_dup): deleted: FD capability will be added to other - procedures. - Remove support for the FD object type: scm_tc16_fd, scm_fd_print, - scm_fd_free, fd_smob, scm_intern_fd. - (scm_open): renamed from scm_sys_open. Return a port instead of - an FD object. Make the mode argument optional. - (scm_sys_create): deleted, it's just a special case of open. - (scm_init_filesys): move interning of constants O_CREAT etc., - here (were previously using SCM_CONST_LONG macro). - Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT. - don't newsmob fd. - (numerous _sys_ procedures): remove gratuitous _sys_ from names. - include "fports.h" and <stdio.h> - (scm_stat, scm_select): don't support FD objects. - - * error.h: adjust scm_syserror_msg prototype. - * error.c (scm_syserror_msg): take an extra argument for errno. - Using the global value didn't always work, since it could be - reset by procedure calls in the message or args arguments. - - * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined. - I don't understand why the check was there (and what about the - ultrix check?) - - * strop.c (scm_string_copy): allow shared substrings to be copied. - - * unif.h: corresponding change to prototypes. - * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x): - recognize two new optional arguments: offset and length. Allow - the port argument to be an integer (file descriptor, for scsh). - Include <unistd.h> for "read" prototype. - -Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz> - - * socket.c: don't include filesys.h. - -Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz> - - * Makefile.am: add AWK=@AWK@ (?) - - * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default, - errnos_get.c. - Add a rule to generate errnos.c from errnos. - * error.c (scm_init_error): include errnos.c. - * errnos_cnvt.awk: new file, converts the list of errno codes to - C expressions. - * errnos_get.c: new file. - * errnos.default: new file, contains errnos to try if they can't - be extracted from errno.h. - * configure.in: if using GCC, try and extract errno codes from - errno.h. - Added AC_PROG_AWK. - -Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de> - - * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL. - * Makefile.am: Made libguile into a libtool library. - * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags. - Set libtool_libs to indicate that libguile is a libtool library. - See guile/ChangeLog for details. - * .cvsignore: ignore "*.lo", the libtool library objects. - -Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz> - - * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS. - use htons in getservbyport argument. - -Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com> - - * ports.h (SCM_PTOBNUM): Removed extraneous semicolon. - * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a - duplicate. - - * objprop.c (scm_object_property): No need to take the CDR of the - value returned by scm_object_properties, since Aug 20 change. - - * configure.in: When checking for struct linger, #include - <sys/types.h> as well as <sys/socket.h>. I've never known - <sys/types.h> to cause any portability problems, and Solaris's - <sys/socket.h> needs it. - * configure: Rebuilt. - - I think the Sun compiler has chosen a perverse way to interpret - ANSI declarations combined with K&R definitions. We'll - appease it a little bit. But when it invades France, we fight. - * print.c (scm_iprlist): Change 'tlr' argument to an int. - * print.h (scm_iprlist): Here too. - * numbers.c (scm_divbigdig): Change definition to match - declaration in numbers.h. - * unif.c (scm_makflo): Change definition to match declaration in - unif.h. - - * init.c (scm_boot_guile): Don't return the value of - scm_boot_guile_1.

I have a feeling this function is a bad idea anyway --- - one should always test for features, not systems. - - * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous - semicolons. Only pure luck kept this from being noticed earlier. - -Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth> - - * socket.c (scm_recvfrom): Added missing semicolon. - -Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz> - - * socket.c (scm_recvfrom): allow buff_or_size to be a list containing - the buffer and start and end positions for scsh networking - implementation. - -Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com> - - * configure.in: Revert previous change to this file; the problem - is due to transient automake weirdness. - * configure: Rebuilt. - - * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not - PLUGIN/guile.libs. configure generates the latter from the former. - * Makefile.in: Rebuilt. - - * configure.in: Call AM_PROG_INSTALL; the automake manual says we - need this if we install scripts, like guile-snarf. - * configure: Rebuilt. - -Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de> - - * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING - -Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz> - - * socket.c (scm_addr_vector): fix faulty scm_listify. - -Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de> - - * read.c (scm_lreadr): Encountering EOF after skipping a SCSH - style block comment is no longer considered an error. - -Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de> - - * PLUGIN/guile.libs.in: New file. - * PLUGIN/guile.libs: Removed from repository. - * configure.in: Create PLUGIN/guile.libs from - PLUGIN/guile.libs.in. This is for including additonal libraries - needed for dynamic linking. - * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in - instead of PLUGIN/guile.libs. - - * Makefile.am: Added explicit dependency "dynl.o: dynl.x". - -Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com> - - * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all - occurrences of the given element from the list, not just the - first. This is how the Emacs Lisp functions behave, how the - analogous Common Lisp functions behave, and (I believe) how the - older Maclisp functions worked. I realize that this change may - break code, but it seemed better to break it before the Guile - release than after. - - * gc.c (scm_protect_object, scm_unprotect_object): New functions. - Their prototypes were already present in gc.h, but they weren't - implemented. - (scm_init_storage): Initialize scm_protects. - * root.c (scm_protects): New element of scm_sys_protects. - - * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb. - -Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com> - - * libguile.h: Added #include "libguile/net_db.h". - - * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct - 30 change. That file is only meant for communication between the - configuration process and load.c. If code linked against libguile - wants to get at the paths mentioned in libpath.h, it can call - functions declared in load.h. - -Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * libguile.h: Removed #include "libguile/fdsocket.h" - - * net_db.c: Added #include <sys/socket.h>. - -Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz> - - * filesys.c (scm_input_waiting_p): use select in preference to - FIONREAD, since the latter doesn't detect EOF. - Throw error if neither select nor FIONREAD available. - - * socket.c (scm_connect): take a port, not a fd object. - (scm_fill_sockaddr): throw an error if fam is not recognised. - (scm_bind): use scm_fill_sockaddr. - (scm_listen): take a port, not a fd object. - (scm_accept): take and return a port. return #f in the car if - address can't be got - (scm_sock_fd_to_port): new procedure. - (scm_socket): use scm_sock_fd_to_port. - (scm_addr_vector): throw error if unrecognised address type. - take an extra argument with the calling procedure name. - (scm_getsockname): take a port. return #f if address can't be got. - (scm_getpeername): take a port. return #f if address can't be got. - (scm_recvfrom): take a port. return #f for address component if can't - be got. - (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown, - scm_setsockopt, scm_recv, scm_send): take a port not a fd object. - -Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com> - - * throw.c (scm_internal_catch): Make body funcs and handler funcs - use separate data pointers, to allow them to be designed - independently and reused. - (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): - Renamed from catch_body, catch_handler, and uncaught_throw; made - generically useful. - (struct scm_catch_body_data): Renamed from catch_body_data; moved - to throw.h. - (scm_catch): Use the above. - (scm_throw): Don't bother printing a message for an uncaught - throw; we establish a default handler in init. - * throw.h (scm_internal_catch): Prototype updated. - (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New - decls. - (struct scm_body_thunk_data): New structure, used as data - argument to scm_body_thunk. - * init.c (struct main_func_closure): New structure, packaging up - the data to pass to the user's main function. - (scm_boot_guile): Create one. Pass it to scm_boot_guile_1. - (scm_boot_guile_1): Pass it through to invoke_main_func. Use - scm_internal_catch to establish a catch-all handler, using - scm_handle_by_message. This replaces the special-case code in - scm_throw. - (invoke_main_func): Body function for scm_internal_catch; invoke - the user's main function, using the main_func_closure pointer to - decide what to pass it. - * root.c (struct cwdr_body_data): Remove handler_proc member. - (cwdr): Use scm_handle_by_proc instead of cwdr_handler. - (cwdr_handler): Removed. - -Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz> - - * socket.h (SCM_P): update bind prototype. - * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET. - include "feature.h". - (scm_socket): return a port, not a file descriptor object. - include "fports.h" and <unistd.h> - (scm_bind): take a port, not a file descriptor object. - take an extra argument for address args. - - * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST, - INADDR_NONE, INADDR_LOOPBACK. - -Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz> - - * init.c: include net_db.h and not fdsocket.h. - (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket. - - * Makefile.am: corresponding changes. - * socket.h: renamed from fdsocket.h, fix names. - * net_db.h: renamed from socket.h, fix names. - * socket.c: renamed from fdsocket.c. - remove _sys from procedure names. - (scm_init_socket): rename from scm_init_fdsocket. include socket.x. - add "socket" to features list. - * net_db.c: renamed from socket.c. - remove _sys from procedure names. - (scm_init_net_db): rename from scm_init_socket. include net_db.x. - add "net-db" to features list. - include "net_db.h". don't include <sys/socket.h> or - <sys/un.h>. - -Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * tags.h (scm_tags): Removed comma at end of last enumerator. - -Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com> - - Don't use GCC extensions to allocate space for debugging frames. - (Here he goes again! Why do we put up with this?!) - * debug.h (scm_debug_frame): Make the 'vect' member a pointer to - an scm_debug_info structure, not an in-line array of them. Add - 'info' member, to say how many vect elements we've used, for eval - frames. - * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use - a new variable debug_info_end to mark the end of vect, instead of - the address of the 'info' pointer itself. - [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of - &debug to scm_debug_frame *; debug is a real scm_debug_frame now. - (SCM_APPLY): Explicitly allocate space for debug.vect. - * debug.c (scm_m_start_stack): Same, for vframe.vect. - * stacks.c: Adjusted for new debug frame structure. - (RELOC_INFO, RELOC_FRAME): New macros. - (stack_depth, read_frames): Use them, and new scm_debug_frame - element 'info', instead of magically knowing that eval frames have - an info pointer sitting after vect. - (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use - RELOC_FRAME. - (scm_init_stacks): Formatting tweaks. - -Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com> - - Give GCC more control flow information, so it can be sure that - variables aren't used uninitialized. - * error.h (scm_error, scm_syserror, scm_syserror_msg, - scm_sysmissing, scm_num_overflow, scm_out_of_range, - scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error, - scm_misc_error): Tell GCC that these functions never return. - * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure - out the field type, call abort if SCM_ASSERT returns, to placate - the optimizer. - * stacks.c (scm_make_stack, scm_last_stack_frame): abort if - scm_wta ever returns. We can't handle this case anyway, and this - gives the optimizer more information. - * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if - scm_wta ever returns. - - In some cases, the code is fine, but GCC isn't smart enough to - figure that out; this usually happens when one variable is only - initialized and used when a particular condition holds true, and - we know that condition will never change within a given invocation - of the function.

(Thanks to Bernard Urban.) - -Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com> - - It's an "eval closure", not an "eval thunk." A thunk is a - function of no arguments. - * root.h (struct scm_root_state): Renamed - top_level_lookup_closure_var from top_level_lookup_thunk_var. - (scm_top_level_lookup_closure_var): Renamed from - scm_top_level_lookup_thunk_var. - * root.c (mark_root): Uses changed. - * gdbint.c (gdb_eval, gdb_binding): Uses changed. - * init.c (scm_start_stack): Uses changed. - * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses. - Change scheme-visible name to *top-level-lookup-closure* from - *top-level-lookup-thunk*. - -Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com> - - * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we - pass to scm_mark_locations.

The first specifier in - a pair controls inner border, the second the outer border. A - number means cut that number of frames, a procedure object means - cut until that object is found in operator position in a frame. - - * root.c (cwdr): Bugfix. - - * read.c: Recording of positions disabled by default. - - * procs.c (scm_closure_p): New function. - - * posix.c (scm_tmpnam): New function. - - * load.c: Added #include "throw.h". - (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path - ends with '/'. - - * load.c, load.h (scm_read_and_eval_x): New function. - - * eval.c: Renamed debug option "deval" to "debug". - - (scm_eval_x): `eval!' is no longer accessible from the scheme - level. Motivation: We can't allow operations which introduce - glocs into the scheme level. Guile's type system can't handle - these as data. Use `eval' or `read-and-eval!' as replacement. - - * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of - SCM_CONSP since this is a macro!; Set vframe.prev to - scm_last_debug_frame instead of 0. In this way we can look - "above" the virtual start stack frame if we wish. - (scm_debug_hang): New function: Useful for debugging Guile in - certain tricky situations. Will probably be removed later... - - * debug.h: Changed semantics of debug option "backtrace". This - option now only indicates whether we want automatic backtrace at - an error. - -Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * ports.c: #include "filesys.h" - (scm_char_ready_p): input_waiting renamed and moved to filesys.c. - - * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c. - Motivation: This is system specific code which is related to file - I/O. It also may use select. Added code by Gary Houston to - detect presence of character in stdio buffers. - - * libguile.h: #include "libguile/libpath.h" - - * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH --> - SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR, - SCM_SITE_DIR; Install libpath.h among the other include files. - - * load.c, load.h (scm_sys_package_data_dir): New function. - -Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * stacks.h: Bugfix: Don't use tail-array length field as stack - length field! This screwed GC. - -Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * _scm.h: Added #ifndef around definition of macros min and max. - - * __scm.h: Added hooks for threads to plugin to in ints protection - macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER, - SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want - the main code in these macros duplicated and spread over multiple - files. Renamed SCM_THREADS_SWITCHING_CODE -> - SCM_THREAD_SWITCHING_CODE. - -Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de> - - * snarf.h: New file. - * guile-snarf.sh: New file. - * Makefile.in (inner_h_files): Added snarf.h - (ancillary, install, uninstall, distclean): Added actions for - guile-snarf. - (.c.x): Use guile-snarf. - (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh. - (gen_c_files): Note that these depend on guile-snarf. - * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are - now in "snarf.h". Added #include "snarf.h" to get them. - * libguile.h: Added #include "snarf.h". - (Patches applied and tweaked by Jim Blandy.) - -Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com> - - * socket.c: Use K&R style declaration for 'close'; the GNU coding - standards suggest against providing prototypes for system - functions. Thanks to Greg Troxel. - -Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com> - - * strports.c (scm_eval_0str): New function. - #include "read.h", to get prototype for scm_read. - * Makefile.in (strports.o): Update dependencies. - * strports.h: New prototype. - - * numbers.c (scm_integer_p): Renamed from scm_int_p; change its - scheme name from "int?" to "integer?". It seems to do the job. - * numbers.h: Rename prototype too. - * scmhob.h (intp): Change definition to refer to scm_integer_p. I - hope this is right. - - * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p, - scm_num_eq_p): Rename these according to R4RS conventions: call - them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route - to making libguile R4RS compliant without ice-9... - - * load.c (scm_sys_search_load_path): Search for files under all - extensions listed in the %load-extensions variable. If FILENAME - is absolute, return it unchanged, without searching the load path. - (scm_loc_load_extensions): New variable, pointing to - %load-extensions' value cell. - (scm_init_load): Initialize it, and the value it points to. - (scm_primitive_load_path): Improve error reporting. - - * load.c (scm_loc_load_hook): New variable, pointing to value cell - of new Scheme variable %load-hook. - (scm_primitive_load): Apply %load-hook to filename. - -Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz> - - * configure.in: add tests for figuring out whether buffered data - is available in a FILE structure, which is needed by char-ready. - - * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and - FILE_CNT_READPTR. - - * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw - exceptions using misc_error instead of syserror. It seems a bit - odd to throw an exception if a string can't be found in the - environment, but it's consistent with open-file, stat etc. - (simpos.h): remove sys_ from getenv. - - * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error - occurs, throw an error instead of returning errno. Return value - is now unspecified. - (numerous in posix.c and posix.h): removed superfluous sys_ from names. - -Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz> - - * filesys.c (scm_stat2scm): derive file type and permissions from - the stat mode and append them to the returned vector. - There isn't much overhead in doing this and it avoids the need to - work with S_IRUSR et al. in Scheme. - Define symbols scm_sym_regular etc. - (scm_init_filesys): don't intern S_IRUSR etc. - - * load.c: change s_try_load and s_try_load_path to s_primitive_load - and s_primitive_load_path. - - * eval.c, load.c, error.c (scm_wta): use scm_misc_error. - - * error.h: don't declare error symbols. prototype for scm_misc_error. - - * stackchk.c (scm_stack_overflow_key): defined here instead of in - error.c. - - * error.c: use SCM_SYMBOL to set up error keys. - scm_misc_error: new procedure. - -Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com> - - * read.c (scm_lreadr): Recognize SCSH-style block comments; text - between `#!' and `!#' is ignored. - (skip_scsh_block_comment): New function. - - * feature.c (scm_set_program_arguments): New argument, FIRST. - * feature.h: Update prototype. - * init.c (scm_boot_guile_1): Pass new argument to - scm_set_program_arguments. - -Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com> - - * init.c (scm_start_stack): Don't initialize scm_progargs here. - (scm_boot_guile): Call scm_set_program_arguments here, later than - the old initialization. - - * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified - initialization procedure. - - Delete in, out, err arguments; there are other perfectly good - ways to override these when desired. - - Delete result argument; this function shouldn't ever return. - - Rename init_func argument to main_func, for less confusion. - - Delete boot_cmd argument; main_func is more general. - -Add 'closure' argument, to help people pass data to main_func - without resorting to global variables. - - Abort if reentered; don't bother returning an error code. - - Call scm_init_standard_ports to set up the default/current - standard ports; no need to pass them to scm_start_stack. - - Remove code to evaluate the boot_cmd, and start the repl; let - the user do something like that in main_func if they want. - - Remove code to package up a return value; main_func can do any - of that as needed. - - Call exit (0), instead of returning. - (scm_start_stack): Don't initialize the I/O ports here; that's - weird. Delete in, out, err arguments. Move guts to - scm_init_standard_ports, scm_stdio_to_port. - (scm_init_standard_ports): New function, to set up current and - default standard ports. - (scm_start_stack, scm_restart_stack): Make these static. - * init.h (scm_boot_guile): Adjust declaration. - (scm_start_stack, scm_restart_stack): Remove externally - visible declarations for these. - (enum scm_boot_status): Removed; now scm_boot_guile never returns. - - * fports.c (scm_stdio_to_port): New function. Its guts used to be - written out several times in scm_start_stack. - * fports.h: New declaration for the above. - - * feature.c (scm_set_program_arguments): New function. - * feature.h: New declaration for the above. - - * ports.c: Formatting tweak. - -Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth> - - * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c, - ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC - for obtaining the address of a car or cdr field. Motivation: - &SCM_CXR make assumptions about the internal structure of the - SCM_CXR selectors. - - * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC. - Motivation: see SCM_CXRLOC. - - * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h, - srcprop.h, tags.h, throw.c, unif.c: Added new selectors - SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR. - Motivation: Safer use. Some other macros are defined in terms of - these operations. If these are defined using the SCM_SETCXR - (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead - to inefficiency and an <e1> with side-effects could potentially - break. Also, these particular operations are heavily utilized in - the garbage collector. In unoptimized code there will be a - measurable speedup. - - * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c, - eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c, - ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h, - pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c, - procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h, - strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c, - vports.c: Cleaned up use of pairs: Don't make any special - assumptions about the internal structure of selectors and - mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>), - SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc. - (Among other things, this change makes it easier to build Guile - with certain compilers which have problems with casted lvalues.) - -Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se> - - * stacks.c: Improve selection of relevant stack frames when making - a stack object. Introduce one level of indirection in the stack - object to make it possible to "narrow" to a certain region of the - stack. This facilitates making use of more clever algorithms (not - implemented) for selecting relevant frames and gives a cleaner - design since selection of frames can be done independently of - extraction of frames from the real stack. - (scm_stack_id): Also take #t as argument which means look at - current stack. - - * stacks.h: In struct scm_stack: Turn field frames into a pointer. - Turn n_tail into an integer directly representing current number - of frames in stack. Add field tail. - - * ports.c (scm_port_line_x, scm_port_column_x): New mutators. - - * debug.c (scm_make_memoized): Made it available at scheme level. - (scm_unmemoize, scm_memoized_environment): Bugfix: Check for - SCM_NIMP before applying heavier predicates in argument checking. - (scm_local_eval): Also take memoized object as argument. - - * backtrace.c (scm_display_error): Just a safety measure: Stacks - aren't created with zero length, but should such a strange - creature suddenly turn up... - -Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de> - - * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to - `del', for the sake of C++ compilers. (Patch applied by JimB.) - -Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com> - - * variable.c (scm_make_variable): Make the name hint optional, as - documented. - (anonymous_variable_sym): Renamed from variable_sym. All uses - changed. - - * load.c (scm_primitive_load, scm_primitive_load_path): Renamed - from scm_sys_try_load and scm_sys_try_load_path. The Scheme name - of scm_primitive_load_path was also changed to - "primitive-load-path", from "%try-load-path". Callers changed. - We'd like to respect the convention that a function named - "try-mumble" should behave just like the function called "mumble", - but return #f instead of signalling some error. - * load.h: Rename prototypes. - -Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se> - - * print.c (make_print_state, grow_print_state), print.h: Modified - the print state representation: Don't use a tail array for - recording of circular references. Resizing of the print state - structure invalidates the print state pointer. To avoid passing - around an indirect print state reference to all printing - functions, we instead let the print state reference a resizable - vector. - -Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com> - - * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc): - Don't crash when passed an improper list terminated by a - non-immediate value. - -Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com> - - Allocate data for structures on an eight-byte boundary, as - required by the tagging system. - * struct.c (alloc_struct): New function. - (scm_make_struct, scm_make_vtable_vtable): Call it. - * struct.h (scm_struct_n_extra_words): Bump to 3. - (scm_struct_i_ptr): New "field". - * gc.c (scm_gc_sweep): When we need to free the data, use the - information stored by alloc_struct to find the beginning of the - block allocated to the structure, so we can free it. - -Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se> - - * init.c (scm_boot_guile_1): Moved scm_init_struct in front of - scm_init_stacks. - - * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros. - (scm_debug_info): New member: id. - - * stacks.c: Stacks are now represented as structs; Stacks have an - id given to them by `start-stack'. - (scm_last_stack_frame): Added predicates `stack?' and `frame?'. - - * stacks.h: Added declarations of scm_stack_p and scm_frame_p; - Changed stack representation. - - * debug.c (scm_procedure_name): Try procedure property `name' for - compiled closures aswell. - - * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL. - - * eval.c: scm_i_name moved to gsubr.c - (scm_m_define): Record names of all kinds of procedure - objects.

Added - a hook for printing of closures (accessible via print options). - This leads to a split of calls to scm_iprin1 into two classes: - elementary print operations (e. g. the code which prints a smob) - still use scm_iprin1 while top level calls (like scm_display) use - scm_prin1. scm_prin1 begins by clearing the data structure used - to record reference information. - - * print.h: Added declarations of scm_prin1 and scm_prlist. - - * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1 - - * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1 - - * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1 - - * error.c (err_head): scm_iprin1 --> scm_prin1 - - * debug.c: Adjusted header comment. - - * tags.h: Typo. - -Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com> - - * strerror.c: Doc fix. - -Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se> - - * gdbint.c (gdb_read): Now possible to run during GC. - (unmark_port, remark_port): New functions. - - * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR. - - * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead - of allocating a new string object. Also, increase size by - the factor 2 instead of 1.5. - -Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com> - - * __scm.h (SCM_P): Corrected to run under traditional C. - - * _scm.h (SCM_PROC): Extraneous semicolon (outside functions) - removed. - - * async.c: Calls to scm_sysintern corrected. - - * async.h (scm_async_clock): Redundant declaration removed. - - * continuations.c (scm_dynthrow): Redundant declaration removed. - - * debug.c (scm_single_step, scm_memoized, scm_lookup_soft): - Definition typos corrected. - - * debug.h: Missing declarations of functions in debug.c added - (lots). - - * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine): - Missing declarations to functions in eval.c added. - - * filesys.c: Possibly uninitialized variable rv. - - * gc.h (scm_object_addr, scm_unhash_name): Missing - declarations of functions defined in gc.c added. - - * genio.c: Possible typos str_data -> wstr_data. ??? - - * genio.c: Possibly unintended shadowing of local variable - `int c' (gotos out of scope of inner `c'). ??? - - * init.c: Uninitialized `SCM last' may be used. - - * ioext.h: (scm_sys_isatty_p): Typo. - - * list.h (scm_list_head): Missing prototype for function in - list.c added. - - * numbers.c (scm_two_doubles): Changed from extern to static - (is used only within numbers.c). - - * numbers.h: Repeated declarations removed. - - * ports.h (scm_close_all_ports_except): Declaration for the - function defined in ports.c added. - - * posix.h: Missing declarations added. - - * procs.h (scm_make_subr_opt): Missing declaration added. - - * socket.h (scm_sys_gethost): Missing declaration added. - - * socket.h: Redundant declarations removed (they are in fdsocket.h). - - * srcprop.h (scm_set_source_property_x, scm_finish_srcprop): - Missing declarations added. - - * stime.h (scm_get_internal_real_time): Repeated declarations removed. - - * struct.c: Uninitialized variable `SCM answer' may be used. - - * unif.c (l2ra): Declaration prototype. - - * unif.c (scm_array_equal_p): Dummy definition removed (it is - defined in ramap.c). - - * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p): - Redundant declarations removed (they are in ramap.h). - - * variable.h (scm_make_udvariable, - scm_make_undefined_variable): Declaration corrected to - correspond variable.c. - - * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x): - Missing declarations added. - -Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com> - - * Makefile.in (distclean): Don't forget to delete fd.h. - -Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com> - - * fd.h.in, tags.h: Trivial cleanups. - - * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and - marksweep.h just declared functions from gc.c. - * gc.h, libguile.h: Don't #include "marksweep.h". - * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit - marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other - dependencies updated. - - * libguile.h: Don't #include "files.h"; it's been deleted. - - * files.c (scm_sys_delete_file): Moved to filesys.c. - File is now empty; deleted. - * files.h: Deleted. - * filesys.c: scm_sys_delete_file is now here. Remove - #if's; they seem to rely on remnants of an old portability - regimen. If the problems come up again, solve them properly, - using autoconf. Specifically: Don't test M_SYSV, and #define - remove to be unlink if it's #defined; don't use remove just - because HAVE_STDC_HEADERS is #defined. - * filesys.h: Add declarations for scm_sys_delete_file. - * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit - files.o, files.h, files.c, and files.x. - * init.c: Don't #include "files.h", and don't call scm_init_files. - - Use SCM_P instead of PROTO; the latter intrudes on the user's - namespace. - * params.h: Deleted; definition of SCM_P moved to... - * __scm.h: ... here, where it replaces PROTO macro. - * libguile.h, smob.h: Don't #include "params.h". - * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h, - smob.h: Fix prototypes accordingly. - * Makefile.in: Update dependencies. - (inner_h_files): Remove params.h. - - * gc.c: #include "gc.h"; every module should include its header, - to let the compiler cross-check the declarations against the - definitions. - - * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h, - simpos.h: #include "libguile/__scm.h". - -Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com> - - * init.c: Don't forget to #include smob.h and init.h. - * Makefile.in: Dependencies updated. - - * smob.h: Use PROTO instead of #if __STDC__. - - * continuations.c (scm_dynthrow): Use PROTO, not SCM_P. - - * __scm.h: Doc fixes. - - * __scm.h, libguile.h: Use "quotes" in the #includes, not - <angles>; this allows `make depends' to work properly. - - * libguile.h: #include smob.h and pairs.h before the others; they - define typedefs used by other headers. - - C files should #include only the header files they need, not - libguile.h (which #includes all the header files); the pointless - recompilation was wasting my time. - * Makefile.in (all .o dependency lists): Regenerated. - * libguile.h: Don't try to get a definition for size_t here... - * __scm.h: Do it here. - * _scm.h: Since this is the internal libguile header, put things - here that all (or a majority) of the libguile files will want. - Don't #include <libguile.h> here; that generates dependencies on - way too much.

Badros <gjb@cs.washington.edu> + + * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off + SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for + argument mismatches (along with the FUNC_NAME macro checking) by a + static tool that runs directly over the .c files. + + * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The + docstring is still missing from the .doc file; it just gives the + name of the C function that gets called instead. + + * guile-doc-snarf.awk: Be sure to touch the output files to help + make out. Also handle SCM_REGISTER_PROC better, and change the + output format slightly. + +Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu> + + * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for + guile-doc-snarf script. + + * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc + extraction system. Builds foo.x, foo.doc from foo.{c,cc}. + There are dependencies between these files and snarf.h. This + replaces guile-snarf. + + * guile-snarf.in: Drop everything after $$$ for the new snarf.h + macros. This is obsoleted by guile-doc-snarf, but kept here for + now for good measure. + + * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to + bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating + .doc files to use guile-doc-snarf. Update the rule for creating + .x files to use guile-doc-snarf. + +Sun Dec 12 12:31:38 1999 Greg J.

Badros <gjb@cs.washington.edu> + + * scm_validate.h: Added the FSF copyright to the top. + + * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of + SCM_ASSERT w/ SCM_OUT_OF_RANGE. + +Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu> + + * Makefile.am: Added scm_validate.h to modinclude_HEADERS. + + * *.c: Pervasive software-engineering-motivated rewrite of + function headers and argument checking. Switched SCM_PROC, + SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names + later, but was useful to keep old versions around while migrate) + that has docstrings and argument lists embedded in the GUILE_PROC + macro invocations that expand into a function header. Use lots of + new SCM_VALIDATE_* macros to simplify error checking and reduce + tons of redundancy. This is very similar to what I did for Scwm. + + Note that none of the extraction of the docstrings, nor software + engineering checks of Scwm is yet added to Guile. I'll work on + that tomorrow, I expect. + + * chars.c: Added docstrings for the primitives defined in here. + + * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added + SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC + still remains for now. Changed naming convention for the s_foo + string name of the primitive to be s_scm_foo for ease of use with + the macro. + + * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify + argument checking through guile. Maybe some of these should be + folded into the header file for the types they check, but for now + it was easiest to just stick them all in one place. + +1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb) + + * smob.c (scm_smob_prehistory): initialize allocated smob + + * tags.h: new tag: scm_tc16_allocated + + * gc.c (scm_gc_for_newcell): set the car of the new cell + to scm_tc16_allocated + * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated + (scm_gc_mark): mark allocated cells. + +1999-12-09 Greg J.

Four representations + for procedure-with-setters were considered before selecting this + one: + + 1. A closure where the CODE and ENV slots are used to represent + the getter and a new SETTER slot is used for the setter. The + original getter is stored as a `getter' procedure property. For + closure getters, the CODE and ENV slots contains a copy of the + getter's CODE and ENV slots. For subr getters, the CODE contains + a call to the subr. + + 2. A compiled closure with a call to the getter in the cclo + procedure. The getter and setter are stored in slots 1 and 2. + + 3. An entity (i.e. a struct with an associated procedure) with a + call to the getter in the entity procedure and the setter stored + in slot 0. The original getter is stored in slot 1. + + 4. A new primitive procedure type supported in the evaluator. The + getter and setter are stored in a GETTER and SETTER slot. A call + to this procedure type results in a retrieval of the getter and a + jump back to the correct eval dispatcher. + + Representation 4 was selected because of efficiency and + simplicity. + + Rep 1 has the advantage that there is zero penalty for closure + getters, but primitive getters will get considerable overhead + because the procedure-with-getter will be a closure which calls + the getter. + + Rep 3 has the advantage that a GOOPS accessor can be a subclass of + <procedure-with-setter>, but together with rep 2 it suffers from a + three level dispatch for non-GOOPS getters: + + cclo/struct --> dispatch proc --> getter + + This is because the dispatch procedure must take an extra initial + argument (cclo for rep 2, struct for rep 3). + + Rep 4 has the single disadvantage that it uses up one tc7 type + code, but the plan for uniform vectors will very likely free tc7 + codes, so this is probably no big problem.

We can not use the dynamic root + of the surround since that root belongs to another thread => stack + is not handled correctly. It may seem ugly to use this extra + layer, but the extra cost in terms of execution time is really + negligible compared to the total amount of time required to create + a thread, and it would reduce maintainability to duplicate the + crucial and complicated steps performed by cwdr. + + * __scm.h (SCM_ASYNC_TICK): Removed thread switching code. + (SCM_ALLOW_INTS): Added thread switching code before interrupts + get re-enabled. The important effect of this is that interrupts + are blocked during thread switching so that thread data structures + don't risk getting messed up by an unfortunate signal. + (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0 + seems to do more aggressive optimization which actually move + instructions around in these macros in a fatal way. Therefore: + Introduce Anthony's SCM_FENCE macro!

Signals must instead be + delivered when the asyncs run *after* the end of the critical + section in scm_internal_select. But this also means after context + switch so that the signal will be delivered to a different thread. + To avoid this, I have changed the protocol of + coop_wait_for_runnable_thread and friends so that they are allowed + to return the original thread. So, if a signal arrives during + scm_internal_select, we won't any longer be forced do a context + switch, but can remain in the same thread and deliver the signal + to it. + + * async.c, async.h (asyncs_pending): Renamed asyncs_pending --> + scm_asyncs_pending and made it global. + + * iselect.c: Small fixes. + + * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock, + coop_condition_variable_init, coop_condition_variable_wait, + coop_condition_variable_signal): Changed return type from `void' + to `int'.
