-
- * gh.h: Fix constness of prototypes for the above.
-
- * vectors.c: Include "unif.h" to avoid a warning about missing

-
-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>

- (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
- tag 29 for now.
-
- * __scm.h: don't mention LONGLONGS.
-
- * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
- replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
-
-1999-11-17 Gary Houston <ghouston@freewire.co.uk>
-
- * 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.
-
-1999-11-16 Gary Houston <ghouston@freewire.co.uk>
-
- * error.c: (various): use scm_cons instead of scm_listify
- to build short lists.
-
-1999-11-03 Gary Houston <ghouston@freewire.co.uk>
-
- * socket.c (scm_fill_sockaddr): zero the address structure before
- 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. (Thanks to Bernard
- Urban and Greg Harvey.)

-1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * throw.c (handler_message): Display backtrace if backtraces
- enabled.
-
-1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
-
- * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
- the autogen.sh script to create generated files like these.
-
- * numbers.c (scm_string_to_number): Signal an error if radix is
- less than two. (Thanks to Jorgen Schaefer.)
-
- * print.c (scm_write, scm_display, scm_newline, scm_write_char):
- Don't assume that the current output port is valid. Somebody
- might close it. (Thanks to Bernard Urban.)
-
-1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * scmconfig.h.in: Regenerated.
-
- * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
-
-Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
-
- * __scm.h: Fix a bunch of macros that were missing do-while(0)
- sandwiches.
-
- * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
- semicolon) exposed by the above change.
-
-1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
-
- * stacks.c: Avoid compiler warning re: unitialized var.
-
- * scmconfig.h.in: Added DEBUG_FREELIST
-
- * pairs.h: Fix macro that was not do-while(0) sandwiched.
-
- * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
- scm_map_free_list
-
-1999-09-23 Gary Houston <ghouston@freewire.co.uk>
-
- * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
- instead of in scm_init_filesys.
-
- * init.c (scm_boot_guile_1): don't call scm_init_posix or
- scm_init_filesys unless HAVE_POSIX is defined.
- don't call scm_init_netdb or scm_init_socket unless
- HAVE_NETWORKING is defined.
-
- * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
- net_db.c, socket.c: moved here from libguile_la_SOURCES.
-
-1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
-
- * root.c (scm_make_root): Initialize all the fields of the new
- root. GC could happen any time, you know. (Thanks to Greg
- Harvey.)
-
- * numbers.c (scm_number_to_string): Signal an error if radix is
- less than two. (Thanks to Jorgen Schaefer.)
-
- * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
- so automake will actually generate rules for it.
- * Makefile.in: Regenerated.
-
-1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
-
- * backtrace.c: #include "_scm.h" before testing whether
- HAVE_UNISTD_H is #defined.
-
-1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
-
- * read.c (scm_read): Don't assume that scm_cur_inp is always open.
- * ports.c (scm_read_char): Same.
- * ioext.c (scm_read_line): Same.
- (Thanks to Bernard Urban.)
-
-1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
- in SCM_ASSERT macro.
- numbers.c: Removed #ifndef SCM_RECKLESS at places where type
- checking may invoke a generic. (Thanks to Michael Livshin.)
-
- * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
-
- * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
- scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
- generic function if the asubr is called with only one arg.
-
-1999-09-20 Gary Houston <ghouston@freewire.co.uk>
-
- * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
- HAVE_RESTARTABLE_SYSCALLS.
- (scm_init_scmsigs): use siginterrupt if it's available. not
- everyone who has restartable syscalls has SA_RESTART it seems.
-
- (scm_sigaction): use scm_num2long/scm_long2num when converting
- SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
- scm_integer_p to test the type.
-
-1999-09-18 Gary Houston <ghouston@freewire.co.uk>
-
- * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
- HAVE_RESTARTABLE_SYSCALLS.
-
- * strports.c (scm_strport_to_string): create the string from
- pt->read_buf instead of an expression that evaluates to the
- same thing.
-
- * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
- from the port: the port's buffer may not be NUL terminated.
-
-1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
-
- * Makefile.am (.c.x): Added missing semicolon after `false'.
-
-1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * print.c (scm_iprin1): Turn `write' and `display' into
- primitive generics and use their associated generic functions in
- scm_iprin1 for GOOPS objects.
-
- * backtrace.c: #include <unistd.h> if present.
-
-1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
-
- * Makefile.am (.c.x): Don't create a subshell just to delete the
- .x file and return false.
- * Makefile.in: Regenerated.
-
-1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * feature.c (scm_create_hook): New function. Replaces
- scm_make_named_hook which is now deprecated.
- (scm_make_hook_with_name): New primitive.
- (print_hook): Hooks now print in a fancy way.
-
-1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
- dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
- feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
- procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
- struct.h: Updated copyright notices.

- adaptively adjusting fancy printing parameters and cut output if
- necessary.
- (scm_display_application): Check args.
-
-1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
-
- Change the name of the objects returned by OPENDIR from
- "directory" to "directory stream". A predicate named "directory?"
- would be confusing.
- * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
- At the Scheme level, "directory?" -> "directory-stream?".
- (scm_dir_print): Use the phrase "directory stream" in printed form.
- * filesys.h (scm_directory_stream_p): Prototype renamed
- accordingly.
-
- * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
- be removed by `make distclean', since it's generated by configure.
- * Makefile.in: Regenerated.
- (Thanks to Robert Bihlmeyer.)
-
- * strop.c (scm_substring_move_x): Signal an error if start1
- doesn't come before end1. (Thanks to Karoly Lorentey).
-
- * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
- calling SCM_NIMP. (Thanks to Karoly Lorentey).
-
- * version.c (scm_libguile_config_stamp): Deleted. See
- corresponding change to ../ice-9/boot-9.scm.
- * versiondat.h.in: Remove definition for GUILE_STAMP.
- * version.h: Delete prototype.
- * Makefile.in: Regenerated.
-
-1999-09-11 Gary Houston <ghouston@easynet.co.uk>
-
- * filesys.c (scm_directory_p): new procedure "directory?" Returns
- a boolean indicating whether its argument is a directory
- port as returned by opendir (thanks to Dirk Herrmann for the
- suggestion.)
-
-1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * backtrace.c (display_frame_expr): Don't print a newline.
- (display_frame): Print the newline here instead.
- (display_backtrace_body): Don't print "Backtrace:".
- (scm_backtrace): Print "Backtrace:" here instead.
-
-1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * procs.c (scm_setter): Signal WTA if handed an entity or operator
- lacking a setter.
-
- * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
- primitives. (Thanks to Greg Badros);
- (scm_hook_to_list): New primitive; Hooks are now smobs.
-
-1999-09-08 Gary Houston <ghouston@easynet.co.uk>
-
- * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
- of #f for the 10th vector element to avoid an exception
- seen by Bernard Urban.
- (scm_mktime): unneeded ASSERT removed.
-
-1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
-
- * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
- if args don't match.
-
- * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
-
-1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * numbers.c: Converted comparison operations to dispatch on
- generic if args don't match.
-
- * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
-
-1999-09-06 James Blandy <jimb@mule.m17n.org>
-
- * guile-snarf.c: Deleted. Snarfing should respect CPP
- conditionals, so it needs to actually run CPP. Bleah.
-
-1999-09-05 James Blandy <jimb@mule.m17n.org>
-
- Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
- * guile-snarf.in: Be sure to exit with an error if CPP does.
- * Makefile.am (.c.x): Delete the .x file and exit with an error
- status if guile-snarf exits with an error status.
- * Makefile.in: Regenerated.
-
- * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
- scm_makekey, which doesn't exist any more. Guess nobody's using
- this.
-
- * guile-snarf.c: New implementation of guile-snarf, meant to be
- more robust than the shell script. I think it's complete, but I
- haven't tested it at all, and I haven't changed the build process
- to actually use it. We should compare its output against that of
- the existing shell script, for all source files.
-
- * guile-snarf.c (parse_args): Abort if we haven't handled some
- character type.
-
-1999-09-03 James Blandy <jimb@mule.m17n.org>
-
- * load.c (scm_search_path): If the filename has any extension at
- all, ignore the entire list of extensions. Also, don't check whether
- the file is accessible. If the file exists, accessible or not, we
- should return it. Inaccessible files should cause an error later.
- (Thanks to Keisuke Nishida for the suggestions.)
-
-1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
-
- * gc.c (cleanup, scm_init_storage): Use on_exit if present and
- atexit not available. (sunos4.1.4 needs it.)
-
-1999-09-01 James Blandy <jimb@mule.m17n.org>
-
- I take it all back --- bcopy does handle overlapping source and
- destination areas correctly. At least on every system I could
- find. But it is better to use AC_REPLACE_FUNCS than to introduce
- new CPP conditionals.
- * memmove.c: New file, implementing memmove in terms of bcopy.
- * scmconfig.h.in: Regenerated.
-
- Allocators should use the `void *' type for generic pointers.
- * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
- argument and return types.
- * gc.h: Corresponding changes to prototypes.
- (Thanks to Forcer.)
-
-1999-08-31 James Blandy <jimb@mule.m17n.org>
-
- * numbers.c (scm_init_numbers): Claim to support the `complex'
- feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
-
- * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
- find (ice-9 boot-9) when Guile was compiled in a separate
- directory from the source. (Thanks to Rodney Brown.)
- * Makefile.in: Regenerated.
-
- * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
- table lengths by the size of a single element when growing the
- table. (Thanks to Bill Schottstaedt.)
-
-1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
- SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
- since that cuts down the time for type dispatch by 50%.
-
-1999-08-30 James Blandy <jimb@mule.m17n.org>
-
- * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
- not a correct substitute for memmove, because it doesn't handle
- overlapping source and destination areas on many platforms.
- Overlaps are the primary reason to use memmove in the first place.
- * ports.c (scm_ungetc): Same.
- * strop.c (scm_substring_move_x): Same.
-
-1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
-
- * gc.c (scm_init_storage): Skip registration of cleanup on systems
- which lack atexit. (Is it important that cleanup is made
- properly? Maybe we should replace all `exit' with `scm_exit' and
- call cleanup there?)
-
- * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
- scm_struct_free_standard, scm_struct_free_entity): Declared to
- return scm_sizet instead of size_t.
-
- * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
- there on sunos4.1.4.)
-
-1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
- Account for the case when second argument is unbound.
-
- * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
- (Thanks to Karoly Lorentey.)
-
- * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
- isn't present. (Thanks to Suzuki Toshiya.)
-
- * ports.c: Use ANSI C prototypes in definitions. (Thanks to
- Bernard Urban.)
-
- * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
- Bernard Urban.)
-
- * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
- Bernard Urban and Ian Grant.)
-
- * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
- again. (1.3.4 will be binary incompatible with 1.3.2 because of a
- change in the representation of entities and operators.)
-
-1999-08-29 Gary Houston <ghouston@easynet.co.uk>
-
- * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
- don't allocate zero bytes (thanks to Bill Schottstaedt).
-
-1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * procs.c (scm_setter): Converted to use generic dispatch.
-
- * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
- correctly.
-
- * load.c (scm_search_path): Don't try extensions which already are
- present at the end of the filename.
- (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
-
- * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
-
- Cleanup and simplification of generic method dispatch.
- Also, the quadruple representation of entity and operator
- procedures has been replaced with single.
-
- * tags.h (SCM_IM_HASH_DISPATCH): Removed.
-
- * print.c (scm_isymnames): Removed #@hash-dispatch.
-
- * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
- from eval.c; Support 0 arity methods.
- (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
- (scm_apply_generic_env): Removed.
- Replaced slots proc0-3 with procedure.
-
- * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
- SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
- SCM_OPERATOR_PROCEDURE.
- (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
- SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
-
- * struct.c, struct.h: Replace 4 procedure slots with one.
- (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
-
- * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
- 4.
-
- * eval.c (scm_sym_args): Removed.
- (SCM_CEVAL): Simplified entity application.
- Moved dispatch code to objects.c.
-
- * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
-
-1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * sort.c (closureless): Use scm_eval_body.
-
- * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
- with a symbol as last form was first called normally and then via
- `map' or some other mechanism using primitive apply, an ILOC was
- returned.
-
-1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- This change extends the representation of primitive procedures
- with more data fields, e.g. a place for documentation and true
- procedure properties.
-
- * procs.c, procs.h (scm_subr_entry): New type: Stores data
- associated with subrs.
- (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
- SCM_SUBR_DOC): New macros.
- (scm_subr_table): New variable.
- (scm_mark_subr_table): New function.
-
- * init.c (scm_boot_guile_1): Call scm_init_subr_table.
-
- * gc.c (scm_gc_mark): Don't mark subr names here.
- (scm_igc): Call scm_mark_subr_table.
-
-
- This change implements a scheme for letting a generic work as a
- shadow for a primitive procedure. If the primitive procedure
- can't dispatch on its arguments, control is left over to the
- generic. Normal wrong type arg errors will be generated until the
- user has hung the first method on the primitive.
-
- * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
-
- * procs.c, procs.h (scm_subr_p): New function (used internally).
-
- * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
-
- * objects.c, objects.h (scm_primitive_generic): New class.
-
- * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
-
- * print.c (scm_iprin1): Print primitive-generics.
-
- * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
- SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
-
- * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
- SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
- primitives). NOTE: This means that it is now *required* to use
- SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
- obscured representation that will be removed in the future anyway,
- so backward compatibility is no problem here).
-
- * numbers.c: Converted most numeric primitives (all but bit
- comparison operations and bit operations) to dispatch on generic
- if args don't match.
-
-
- Better support for applying generic functions.
-
- * eval.c, eval.h (scm_eval_body): New function.
-
- * objects.c (scm_call_generic_0, scm_call_generic_1,
- scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
- functions.
-
-
- Optimization of the generic function dispatch mechanism.
-
- * eval.c (SCM_CEVAL): Apply the cmethod directly after having
- called scm_memoize_method instead of doing a second lookup.
-
- * objects.h (scm_memoize_method): Now returns the memoized cmethod.
-
-
- Bugfix
-
- * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
- scm_sysintern so that the binding connected with the subr name
- isn't cleared when we give set = 0.
-
-
-1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- More transparent handling of ports with print states.
-
- * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
- SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
- instead of a pair of a port and a print state. We'll need to cons
- once extra in scm_printer_apply but the type system will be
- cleaner, it will mix better with GOOPS, and, it will be even more
- transparent to the user.
-
- * print.c (scm_get_print_state): New procedure: Given an output
- port, return the print state associated to it in the current print
- chain, if one exists;
- (scm_port_with_print_state): New procedure: Associate a
- print-state with a port.
- (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
- (scm_printer_apply): Wrap port and pstate as a smob;
- (print_state_printer): Removed.
-
- * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
-
- * eval.c (scm_init_eval): Use scm_make_smob_type instead of
- scm_newsmob.
-
- * ports.c (scm_output_port_p): Bugfix: Coerce output port before
- testing (otherwise the port-print-state trick won't be transparent
- to the user; one example where this caused problems was in the
- (ice-9 format) module).
-
-1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
- SCM_UNSPECIFIED instead of the set value.
-
-1999-08-20 James Blandy <jimb@mule.m17n.org>
-
- * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
-
- * ports.h (enum scm_port_rw_active): New enum, containing
- SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
- zero). The debugger knows about enums, but doesn't know about
- #defines.
- (typedef scm_port): Declare rw_active member to be an enum
- scm_port_rw_active.
- * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
- instead of zero.
- * ports.c (scm_add_to_port_table): Same.
- * strports.c (st_flush, st_end_input): Same.
-
- * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
- scm_must_realloc, and scm_done_malloc as appropriate.
-
-1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * sort.c (quicksort): Added condition to protect the algorithm
- from crashing the interpreter if the less predicate is buggy.
-
-1999-08-19 Gary Houston <ghouston@easynet.co.uk>
-
- * fports.c (fport_write): fix line-buffering mode again.
- (scm_open_file): recognise 'l' for line-buffering.
- (scm_setvbuf): recognise _IOLBF for line-buffering.
-
-1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * Makefile.am (libguile_la_LDFLAGS): Increased the version number
- of libguile to 5.0.
-
- * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
- evaluating closures.
-
-1999-08-18 Gary Houston <ghouston@easynet.co.uk>
-
- * fports.c (fport_write): use memcpy instead of strncpy, in case
- the data contains NUL.
-
-1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
-
- * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
- read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
- scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
- scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
- scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
- scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
- scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
- scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
- scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
- scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
- scm_sym_ as prefix for symbols.
-
- * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
-
- * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
- scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
- scm_sym_define, scm_sym_letrec, scm_sym_atapply,
- scm_sym_atcall_cc): Made global.
-
-1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c (scm_sym_args): Made global.
-
- * objects.c (scm_set_object_procedure_x): Disallow setting of
- procedures for pure generic functions.
-
-1999-08-12 Gary Houston <ghouston@easynet.co.uk>
-
- * ports.c (scm_seek): one more: was scm_lseek. Also changed the
- Scheme name from lseek to seek, but lseek was added recently so
- it shouldn't be a big problem.
- * ports.c, gdbint.c, ioext.c: changed callers.
-
-1999-08-11 Gary Houston <ghouston@easynet.co.uk>
-
- * fports.c (fport_input_waiting): if select is used, return 1
- instead of whatever FD_ISSET expands to. maybe it will be useful
- to interpret the value from the input_waiting ptob procedure as a
- lower bound on the number of bytes available.
-
- * Mikael asked for a few names to be changed...
-
- * ports.c (scm_make_port_type): take the write procedure as the
- second argument instead of the flush procedure.
- * ports.h (scm_ptob_descriptor): rename the ptob procedures:
- fflush -> flush, read_flush -> end_input, fclose -> close,
- fill_buffer -> fill_input, ftruncate -> truncate,
- input_waiting_p -> input_waiting.
-
- * ports.c (end_input_void_port): was read_flush_void_port.
- (scm_set_port_end_input): was scm_set_port_flush_input.
- (scm_set_port_flush): was scm_set_port_write.
- (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
- (scm_end_input): was scm_read_flush.
- (scm_fill_input): was scm_fill_buffer.
- (scm_flush): was scm_fflush.
- * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
- (fport_end_input): was local_read_flush.
- (fport_flush): was local_fflush.
- (fport_close): was local_fclose.
- (fport_truncate): was local_ftruncate.
- (fport_seek): was local_seek.
- (fport_free): was local_free.
- (fport_fill_input): was fport_fill_buffer.
- * strports.c (st_end_input): was st_read_flush.
- (st_truncate): was st_ftruncate.
- * vports.c: (sf_flush): was sfflush.
- (sf_close): was sfclose.
- (sf_fill_input): was sf_fill_buffer.
-
- * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
- change callers.
-
-1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
- forms now contain the expressions to be dispatched upon instead of
- depending on a surrounding lambda or let; Generic function
- dispatch has been optimized; `apply' on a generic function now
- works a little bit strangely. It uses a trick so that the type
- dispatch code in SCM_CEVAL can be reused.
-
- * objects.h, objects.c (scm_apply_generic_env): Added (used by
- apply).
- (scm_operator_p): Added.
- (scm_sym_atdispatch): Added.
- (scm_set_object_procedure_x): Modified to handle the new style
- generic functions.
- (scm_object_procedures): New debugging procedure.
-
-1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c, eval.h (scm_sym_args): Added.
-
- * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
-
- * feature.c, feature.h (scm_c_run_hook): Added.
-
- * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
- cdrxnoap and loopnoap instead of begin and loop.
-
-1999-08-04 Gary Houston <ghouston@easynet.co.uk>
-
- * ports.c (scm_putc, scm_puts),
- * unif.c (scm_uniform_array_write): use scm_lfwrite.
- * ports.c (scm_putc): change type of first argument from int to char.
-
-1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
- SCM_IM_HASH_DISPATCH.
-
- * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
- (scm_si_redfined, scm_si_hashsets): Moved.
-
- * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
- flag which combines type and status info so that the class
- redefinition protocol has zero cost during normal execution.
-
-1999-08-03 Gary Houston <ghouston@easynet.co.uk>
-
- * ports.h (scm_ptob_descriptor): include a write procedure again.
- it's more efficient for unbuffered fports (e.g., sockets.)
-
- * ports.c (scm_puts): use ptob->write.
- * vports.c (scm_make_sfptob): set write proc in ptob.
- * strports.c (scm_make_stptob): set write proc in ptob.
- * ports.c (write_void_port): new procedure.
- * vports.c (sf_write): new procedure.
- * ports.c (scm_lfwrite): use ptob->write.
- * strports.c (st_write): new procedure.
- * fports.c (fport_write): new procedure.
- (scm_make_fptob): set write in ptob to fport_write.
- * ports.h: prototype for scm_set_port_write.
- * ports.c (scm_make_port_type): initialise ptob write procedure.
- (scm_set_port_write): new proc.
-
-1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
-
- * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
- until we've verified that it is actually a port. (Thanks to
- Lorentey Karoly.)
-
-1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
- code, particularly an unnecessary test (len != size, where len ==
- size). (Was this leftovers from debugging code, or have I missed
- something profound?)
-
- * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
- size. (Thanks to James Dean Palmer.)
-
- * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
- (Thanks to Lorentey Karoly.)
-
-1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c (scm_m_expand_body): Use scm_cons_source.
-
- * struct.c (scm_print_struct): Use vtable name.
-
- * print.c (scm_init_print): Set name of print state type.
-
- * stacks.c (scm_init_stacks): Set name of stack type.
-
-1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * eval.c (SCM_CEVAL): Removed old implementation of internal
- define.
-
- * gsubr.c, procprop.h (scm_i_inner_name): Removed.
-
- * debug.c, debug.h (scm_reverse_lookup): Added.
- (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
- internal procedure definitions; Don't use scm_i_inner_name.
-
- * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
- New isym operations.
-
- * eval.h: Added prototypes for multi language support functions.
-
- * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
- improper lists in the low-level representation, since that will
- cause a begin to be prepended at macro expansion.
-
- * eval.c (scm_cons_source): Version of cons which copies source
- properties from an existing cell.
- (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
-
- * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
- procedure source before calling scm_unmemocopy instead of faking
- an environment.
-
-1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
-
- Ported `internal defines' fix from SCM. Original ChangeLog entry:
-
- 1998-07-09 Radey Shouman <radey@colorage.com>
-
- * eval.c (ceval_1): Modifications to allow rewriting of interal
- DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
- body of which it is the CAR is macro expanded by m_expand_body,
- which rewrites internal DEFINE.
-
- (m_expand_body): Added.
-
- (m_macroexp1): Added argument to control error checking:
- m_expand_body may speculatively expand forms in the wrong
- environments. Made argument number checks conditional on
- RECKLESS.
-
- (m_body): Added, error checks bodies and inserts the ISYM tokens.
-
- (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
- call m_body.
-
- (m_cond): (m_case): (m_quote): Modified to avoid destructively
- changing their argument forms. Since m_expand_body
- speculatively macro expands forms the process must be
- reversible.
-
- (m_ident_eqp): Fixed to use proper environment.
-
- (renamed_ident): Added DEFER_INTS_EGC.
-
- Added prototypes for static functions.
-
- * eval.c
-
- (undef_cell): New.
-
- (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
- is false, do not produce an error for unbound variables, return a
- pointer to cell_undef instead.
-
- (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
-
- (scm_m_body): New.
-
- (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
- destructively changing their argument forms. Since m_expand_body
- speculatively macro expands forms the process must be reversible.
-
- (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
- SCM_IM_LET introduced by named lets.
-
- (scm_m_letstar): Use scm_m_body instead of bodycheck.
-
- (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
- scm_letrec. scm_letrec1 does not check for a null binding and
- takes an additional argument to specify the ISYM of the body. Use
- scm_m_body instead of bodycheck.
-
- (scm_m_let): Use scm_m_body instead of bodycheck.
-
- (scm_m_expand_body, scm_macroexp): New.
-
- (unmemocopy): Account for ISYMs introduced by scm_m_body.
-
- (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
- check=1. Throw error for internal defined that have not been
- rewritten by scm_m_expand_body.
-
- * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
- Removed prototype for SCM_APPLY.
-
- * tags.h: Added extern declaration of scm_isymnames.
-
-1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
-
- * lang.c: New file: Beginning of multi-language support.
-
- * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
-
- * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
- (scm_dynamic_wind): Added argument checking for the after guard so
- that we don't add garbage on the dynwind chain.
- (scm_swap_bindings): Added.
-
- * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
- SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
- (scm_isymnames): New isyms for multi-language support.
-
- * eval.c (scm_nil, scm_t): New symbols.
- (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
- forms for multi-language support.
-
-1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
- Added.
- Renamed functions in the random function library interface
- from scm_i_XXX --> scm_c_XXX.
-
-1999-07-25 Gary Houston <ghouston@easynet.co.uk>
-
- * ports.c (scm_putc): fix line-buffering.
-
-1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
- scm_set_ptob_XXX --> scm_set_port_XXX.
-
-1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
-
- * ports.c, ports.h (scm_make_port_type): New interface for
- creation of port types (replaces scm_newptob). Just as for the
- smobs, we need to separate the internal representation of smob
- types from the interface, so that we easily can add new fields and
- rearrange things without caring about backward compatibility.
- This change was forced by the need in GOOPS to create classes
- representing port types.
- (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
- scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

-
- * readline.c (scm_readline): Applied a patch from Greg Harvey to
- get readline support working again: use fdopen to get FILE objects.

-
- * gc.c (scm_init_storage): install an atexit proc to flush the
- ports.
- (cleanup): the new proc. it sets a global variable which can be
- checked by the ptob flush procs to avoid trying to throw
- exceptions during exit. not very pleasant but it seems more reliable.
- * fports.c (local_fflush): check terminating variable and if set
- don't throw exception.

-
- Most of this batch of changes is about how to deal with extended
- types when an object system is loaded into Guile. A nice object
- system is capable of representing Guile's types as class objects.
-
- For example, we want a regular expression to be of class <regex>.
- But regular expressions are smobs which aren't under direct
- control of the object system, so there has to be some mechanism
- which informs the object system that a new class should be created
- which can represent the smob type. I call this a "wrapper class".
-
- * objects.c: #include "smob.h";
- (scm_class_keyword): Removed. (Class is automatically created by
- make_smob_classes.)
- (scm_smob_class): Array of smob classes indexed by smobnum.
- (scm_make_extended_class): "Plugin" function pointer for creation
- of wrapper classes for smob and struct types.
- (scm_class_of): Handle compiled closures. (Currently regarded as
- <procedure>.);
- Use scm_smob_class to handle smob types;
- Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
- through scm_smob_class;
- Handle structs.
-
- * smob.c (scm_newsmob): Also create a wrapper class if
- scm_smob_class has been initialized.
-
- * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
- type code and smobnum.
-
- * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
- (scm_struct_table): Weak key table with auxilliary information for
- struct types. Currently used for names and wrapper classes.
- (scm_struct_ihashq): Hash function for structs.
- (scm_struct_create_handle): Get/create entry in scm_struct_table.
- (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
- for accessing names of vtables. The record implementation in
- boot-9.scm currently uses the setter to record the name of record
- types. When the object system is initialized, it can use this
- information to create wrapper classes with suitable names.
- (scm_init_struct): Allocate scm_struct_table.
- (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
- (struct tags are a finite resource and we might want to restrict
- the use of tags to vtables only. E.g., Goops only uses tags for
- classes.)
- (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
- magic number 5.
- (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
- number -1.
-
- * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
- SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
- Used for access of struct table entries.
-
- * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
- (scm_hash_fold): New procedure. Used to process all entries in a
- hash table (in no particular order).
-
- Argh! For the umpteenth time I got compilation errors because of
- the "intuitive" name `kw'. This has to have an end:
-
- * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
- "kw" --> "keywords" everywhere.
- (I doubt that this will cause big compatibility problems since the
- application interface is unaffected.)
-
- * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
-

-
- * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and

- * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
- (Used to flag certain system procedures which shouldn't turn up in
- backtraces.)
-
- * eval.c (scm_sym_system_module): New symbol. (Used to flag
- modules which aren't "user" modules and the code of which
- shouldn't turn up in backtraces.)

- Extract the lookup closure from an environment.

-
- * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
- procedure throughout.
-
- * print.c (scm_iprin1): Removed extraneous space when printing
- procedure-with-setters.
-
- Entity and operator setter slots were introduced as a complement
- to the <procedure-with-setter> type in order to support entities
- and operators with setters in a reasonable and efficient way.
- * procs.c (scm_procedure, scm_setter): Handle entity and operator
- setter slots.
-
- * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.
- (struct scm_metaclass_operator): New setter slot.
-
- * gc.c (scm_gc_mark): Mark struct setter slot.

-
- Readline paren matching from Greg Harvey, with modifications from
- Mikael Djurfeldt:
-
- * readline.c (in_readline, reentry_barrier_mutex): Make these
- static.
-
- * readline.c: #include <sys/time.h> and "iselect.h", so we can
- control how long we're paused, and threads will run while we're
- paused.
- (match_paren, find_matching_paren, init_bouncing_parens): New
- functions.
- (scm_init_readline): Call init_bouncing_parens.

-
-1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * print.c (scm_iprin1): Use scm_procedure_name instead of
- scm_procedure_property for compiled closures.
-
- * tags.h (scm_tc7_pws): New procedure type. 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.

-
- * random.c: Removed alloca includes.
-
-1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * Makefile.in: This changed, for some reason I don't really
- understand, when I ran automake in the top level directory. This
- may be contamination by Cygnus internal releases. If you re-run
- automake and this change gets reverted, don't worry about it.
-
-1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

- David Eby (1993) "Guardians in a Generation-Based Garbage
- Collector" ACM SIGPLAN Conference on Programming Language Design
- and Implementation, June 1993 ftp://ftp.cs.indiana.edu

- argument checking.
-
-1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- Move the procedure slots of entities to invisible slots (so that
- we can have operator class objects which themselves are entities).

-
-Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
-
- * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
- of syntactic forms, similar to SCM_PROC.
- * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
- forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables

-
-1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * Makefile.in: Regenerated.

-
- * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
- take the address of _into; it might be a register. Just have
- scm_debug_newcell return the new cell.
- * gc.c (scm_debug_newcell): Just return the new cell, instead of
- taking the address of a place to store it as an argument.
- * gc.h (scm_debug_newcell): Change declaration.

- * backtrace.c (display_frame): Made more robust. Doesn't throw an
- error if no source properties can be found for a frame. (Thanks
- to Christian Lynbech.)
-
-1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * objects.h: Removed slots direct_supers and direct_slots from the
- definitions of the rudimentary classes described by objects.h.
-
- * objects.c, objects.h (scm_entity_p): New procedure. Together
- with the predicates scm_procedure_p and scm_struct_p, this
- predicate makes it possible to differ between structs, entities
- and operators.
-
- * modules.c, modules.h (scm_resolve_module): New function.
-
-1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
- SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and

-
- * procprop.h (scm_i_procedure_arity): Added declaration.
-
- * procprop.c (scm_i_procedure_arity): Made global; New code to
- handle operators and entities.
- (scm_procedure_property): No need to call scm_procedure_p since
- scm_i_procedure_arity now does all necessary type checking.
- Added #include "objects.h".
-
- * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
- s_add_hook_x --> s_remove_hook_x.
- (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
- Added #include "procprop.h"
-
- * feature.c, feature.h (scm_reset_hook_x): New procedure.
- (scm_make_hook): Optional argument defines number of arguments to
- the hook.
- (scm_make_named_hook): Take number of args as second arg.
- (scm_run_hook): Renamed from scm_run_hooks (old name defined in
- boot-9.scm for a while); First arg is the hook. The rest are
- arguments passed on to the hook procedures.
-
-1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
- scm_logbit_p): Do the computation in ulongs. This is not as nice
- as doing it in bignums, but at least it's good enough for
- manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
-
- * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
- subexpressions. (Thanks to Charbel Jacquin.)
-
-1998-11-23 Mikael Djurfeldt <mdj@kenneth>
-
- * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
- scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
- (scm_make_named_hook): New function.
-
- * feature.c: Added #include "eval.h".
-
- * modules.c (scm_make_module): Beautify the module.
-
-1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * modules.c, modules.h: New files: C interface to modules. (This
- is necessary in order to interface the object system to Guile
- properly. The guts of these modules will be replaced by the new
- module system in the future.)
-
- * init.c: Added #include "modules.h"
- (scm_boot_guile_1): Call scm_init_modules.
- (invoke_main_func): Call scm_post_boot_init_modules.
-
- * Makefile.am: Added modules.c, modules.x, modules.h.
-
-1998-11-22 Mikael Djurfeldt <mdj@kenneth>
-
- * procs.c: #include "objects.h"
- (scm_procedure_p): Return #t also on structs which are operators.
-
- * objects.c (scm_init_objects): Renamed <standard-metaclass>,
- <operator-metaclass> and <entity-class> to <standard-class>,
- <operator-class> and <entity> in order to conform with STKlos
- naming conventions.
-
- * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
- which isn't an operator.
- (SCM_APPLY): Ditto, but jump to badproc.
-
-1998-11-21 Mikael Djurfeldt <mdj@kenneth>
-
- * eval.c (SCM_CEVAL): Allow structs implanted in code.
- Previously, structs implanted in code were interpreted as forms
- the operator of which was a gloc. We solve this by checking for
- the zero in the emulated vcell in the struct vtable. Since
- implanted structs always will look like forms with a gloc
- operator, execution will only be slowed down by maximally one
- extra test-and-branch per application.
-
- * evalext.c (scm_definedp): Removed check for isyms; Added a
- second optional argument: It is now possible to supply an
- evaluation environment in which to look for the symbol.
-
-1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * readline.c (scm_init_readline): Set
- rl_basic_word_break_characters. (Thanks to Ian Grant.)
-
- * coop.c (coop_condition_variable_wait): Removed
- (coop_condition_variable_wait_mutex): Folded logic of
- coop_mutex_unlock into coop_condition_variable_wait_mutex to
- prevent condvar signal lossage. Previously, another thread could
- start to run after unlocking the mutex but before putting the
- current thread on the wait queue. If that thread then would
- signal the first, the signal would be lost. (Thanks to Christian
- Lynbech.)
-
-1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
- Christian Lynbech.)
-
-1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * objects.c (scm_i_make_class_object): Renamed from
- make_class_object; exported; error checking moved to
- scm_make_class_object and scm_make_subclass_object.
- (scm_make_class_object, scm_make_subclass_object): Use
- scm_i_make_class_object.
- (scm_make_subclass_object): Let the subclass have same metaclass
- as the superclass.
-
-1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * debug.c (scm_debug_options): Bugfix: Set the value of
- scm_stack_checking_enabled_p after setting debug options;
- #include "stackchk.h". (Thanks to Richard Polton.)
-
-1998-11-13 Radey Shouman <rshouman@metro2000.com>
-
- * unif.c (scm_array_contents): removed unnecessary test for 0
- base.
-
-1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
- Replaced by macro `collect' in boot-9.scm.
-
-1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * eval.c (scm_copy_tree): Copy source properties if existent.
-
- * debug.c (scm_start_stack): Copy source when evaluating. (If we
- don't, we may end up passing memoized source to a transformer.)
-
-1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * stack.c (get_applybody): Help function which lookups the first
- body form of the apply closure.
- (read_frames): Prevent the source of the first form of the apply
- closure from being recorded. This would only be confusing.
-
- * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
- Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
-
- * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
-
- * stacks.c (read_frame): Bugfix: Removed lingering `else'
- statement.
- (read_frames): Use SCM_MACROEXPP.
-
-1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
- don't contain interesting information since all arguments are
- present in the frame which applies the compiled closure anyway.);
- Skip the transformer application frames.
-
- * print.c (scm_iprin1): Print gsubrs as primitives.
-
-1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
-
- * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
- that we can identify these in a backtrace. (This change doesn't
- introduce any significant speed penalty.)
-
- * eval.c: Added note about `serial-map' using scm_map.
-
- * read.c, read.h (scm_read_options, scm_read_opts): Removed
- readline options. They should reside in their own options array.
-
- * readline.c, readline.h (scm_readline_options,
- scm_readline_opts): Moved readline options here.
-
-1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * readline.c (scm_read_history, scm_write_history): Bugfix: Use
- SCM_ROCHARS instead of SCM_CHARS.
-
- * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
- not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
-
-1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
- This is quite important since the latter clears the
- FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at

-1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * print.c (scm_iprin1): Removed suspect looking (and indeed
- malevolent) semicolon after test for user supplied closure print
- procedure. (Thanks to Telford Tendys.)
-
- * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
- (scm_memq, scm_memv, scm_member): Do argument checking *before*
- starting to search the list. Removed call to sloppy_mem_check.
-
- * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
- procedures: Same as scm_delq_x et al, but delete maximally one
- element.
-
- * options.c (scm_options, scm_init_options): GC-protect option
- values of type SCM. (Thanks to Telford Tendys.)
-
-1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
- make sure that there always is a "real" scm_lookupcar.
-
-1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * read.c, read.h (scm_read_opts): New read options
- "history-length" and "history-file".
- (scm_read_options): Stifle history to history length.
-
- * readline.c (scm_read_history, scm_write_history): New procedures.
-
-1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * eval.h (scm_macro_eval_x): Removed declaration.
-
- * eval.c (scm_s_expression, scm_s_test, scm_s_body,
- scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
- Renamed and made global.
-
- * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
- (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
-
- * evalext.c, evalext.h: New files. 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_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.

-
- * debug.c, print.c: Added #include "macros.h".

-
- 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
- Richard Polton.)
-
- * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
- gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
- gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
- gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
- gh_new_procedure5_0): Specify argument types, to appease C++
- compilers. (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. (Thanks to Etienne Bernard.)
-
-1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * ports.h: Put text after #endif in comment. (Thanks to Nicolas
- Neuss.)

- * script.c (scm_compile_shell_switches): Define

- it. See today's change to top-repl in ice-9/boot-9.scm.
-
- * filesys.c (set_element, get_element): Make sure that `element'

- * Makefile.in: Regenerated.
-
-1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * unif.c (scm_raprin1): Changed print syntax for byte vectors from
- #bytes(...) to #y(...), and syntax for short vectors from
- #short(...) to #h(...). 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. It also
- introduces complexity in the current reader, both on the C and
- Scheme levels. (The Right solution is probably to change the
- syntax and prototypes for uniform vectors entirely.)
-
-1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
-
- Don't use local_fgets on sockets; ftell doesn't work on sockets.
- (Thanks to Jorgen "forcer" Schaefer.)
- * ports.h (SCM_NOFTELL): New flag.
- * fports.c (local_fgets): If it's set, use the generic fgets.
- * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
-
-1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * script.c (scm_compile_shell_switches): Add handling of -q switch
- (inhibit loading of user init file).
- (scm_shell_usage): Add usage text for -q switch.
- (scm_compile_shell_switches): Always load user init file first if
- it is loaded at all.
-
-1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * stime.c: The CPP hair to determine a value for CLKTCK is weird,
- and is now broken under NetBSD. I can't fathom what it's trying
- to do, so I've replaced it with something that I do understand,
- which seems to work, and which isn't broken on NetBSD. "Progress?
- You Decide." (Thanks to Perry Metzger.)
-
- * regex-posix.c (scm_regexp_exec): Add a cast to remove a
- signed/unsigned comparison.
-
-1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
-
- Warning fixes from Greg Harvey:
- * unif.c (scm_array_set_x): initializer for pos
- * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
- * struct.c (scm_struct_ref, scm_struct_set_x): Added
- initializers for field_type, since EGCS so desparately wants to
- play dumb
- * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
- scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
- when GUILE_DEBUG is defined.
- * dynwind.h (scm_wind_chain): Same.
- * ports.h (scm_pt_size, scm_pt_member): Same.
- * print.h (scm_current_pstate): Same.
- * procs.h (scm_make_cclo): Same.
-
-1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
-
- Handle short and long long uniform arrays properly. (Thanks to
- Clark McGrew.)
- * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
- raeql_1): Add cases for scm_tc7_svect (short vectors) and
- scm_tc7_llvect (long long vectors).
-
- Change the way libguile and boot-9.scm are timestamped, to try to
- get rid of these spurious mismatch warnings. 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

-
- * 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.

-
- * 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,

- 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. (Thanks to Robert Pluim.)
-
- * inet_aton.c (inet_aton): Reassure the compiler that the
- arguments to the <ctype.h> macros are all unsigned characters, not
- signed characters.
-
-1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
-
- Getting rid of more warnings...
- * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
- today's change to ../configure.in.
- * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
- * scmconfig.h.in: Regenertaded.de.,.__
- * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
- (scm_localtime, scm_mktime): Use a const char * to manipulate the
- time zone name.
-

-
- * readline.c (scm_filename_completion_function): Use SCM_PROC to
- declare this, instead of calling scm_make_subr manually.
-
-1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
-
- * readline.h (scm_init_readline): Add prototype for this.

-
-1998-09-30 Mark Galassi <rosalia@cygnus.com>
-
- * gh.h: took out the definitions of vset and vref, since they are
- replaced by the proper vector routines that correspond to the R4RS
- procedures.
-
-1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
-
- * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
- these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
- third argument, a C expression that should result in a SCM value,
- which is used to initialize the variable. Reimplemented
- SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
- Stachowiak.)
-
- * version.h (scm_libguile_config_stamp): Add prototype.
- (From Maciej Stachowiak.)
-
-1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>

- (force 9) is tried. (Thanks to Karl M. Hegbloom.)
-
-1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * print.c (scm_iprin1): Rather than having one i, and using it in
- several places, declare a fresh i local to each block where it is
- used, and give it a signedness appropriate to its use in each case.
- (scm_iprlist): Same.
-
- * print.c (scm_iprin1): Add cast to avoid unsigned/signed
- comparison warnings.
-
- * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
- signed/unsigned clashes.
-
- * posix.h (scm_tmpnam): Added prototype.
-
- * objects.h (scm_set_object_procedure_x, scm_make_class_object,
- scm_make_subclass_object): Add external prototypes.
-
- * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
- comparison is okay here.
-
- * numbers.c (scm_istr2int): Add cast; len is known to be positive.
-
- * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
- (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
-
- * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
- signed/unsigned.
-
- * load.c (swap_port): Make this function static.
-
- * load.c (scm_search_path): Make max_path_len and max_ext_len
- unsigned, since they're compared against string sizes.
-
- * load.c (init_build_info): Make i unsigned.
-
- * ioext.h (scm_read_line): Add prototype.
-
- * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
- scm_hash_fn_remove_x): Make hash bucket index local variable k
- unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
- accurately as possible.
-
- * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
- comparisons, and range checking to make sure those casts are
- harmless.
-
- * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
- signed/unsigned comparisons.
-
- * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
- avoid signed/unsigned comparisons.
- * smob.h (scm_numsmob): Change extern declaration to match.
-

- (scm_current_load_port, scm_set_port_line_x,
- scm_set_port_column_x): New prototypes.
-
- * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
- test code, and it causes warnings.
-
- * gh.h (gh_int2scmb, gh_uniform_vector_length,
- gh_uniform_vector_ref): Added prototypes.
-
- * Makefile.am (libguile_la_SOURCES): Include Scheme-level

-
-1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * options.c (scm_options): Bugfix: Allow empty list of options!
-
- * debug.c, debug.h (scm_single_step): Removed.
- (scm_with_traps): New procedure. This procedure could easily be
- written in Scheme but needs to be highly optimized.
-
- * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
-
- * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
- Check SCM_TRAPS_P before trapping.
-
-1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
-
- Changes to avoid signed/unsigned comparison warnings.
- * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
- (scm_gc_sweep): Make n and j local to the blocks they're used in,
- so they can have appropriate types for each application. Make i
- signed. Use initializers in some spots. I'll probably pay for
- all this tweaking.
- (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
- (scm_must_realloc): Make nm unsigned.
- (init_heap_seg): Make new_seg_index and n_new_objects signed.
- (scm_init_storage): Use prototype-style definition, and make the
- argument unsigned.
- * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
- scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
-
- * filesys.c (scm_readlink): Make local vars rv and size ints, to
- avoid signed/unsigned comparison warnings, and because the return
- value of readlink may be -1. Don't bother casting the third
- argument to readlink.
-
- * filesys.c (scm_dirname, scm_basename): Move these to their own
- page, at the end of the file.
- * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
-
- * eval.h (scm_eval_options_interface): Add external prototype for this.

- Make these prototype declarations, not K&R-style.
-
- * chars.c (scm_tables_prehistory): Add cast, to remove signed/
- unsigned comparison warning.
-
- * appinit.c: File removed. It had a single function in it, empty,
- whose reason for existence is explained in no documentation or
- comment. I think it's there as a default for some Tcl-style
- initialization, but Tcl abandoned that approach a while ago.
- * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
- (BUILT_SOURCES): Remove appinit.x.
- * Makefile.in: Regenerated.
-
-1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * Makefile.in: Regenerated using the last public version of
- automake, not the hacked Cygnus version.
-
-1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
-
- Remove Totoro kludge.
- * Makefile.in, scmconfig.h.in: Regenerated.
- * init.c, readline.c: Don't check if TOTORO is #defined.
-
-1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
-
- * Makefile.am: Adjust for new thread configuration system.
- (INCLUDES): Include the value of THREAD_CPPFLAGS.
- (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
- THREAD_LIBS.
- (THREAD_LIBS): Definition deleted; automake will generate such
- things automatically.
- * Makefile.in: Regenerated.
-
-1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
-
- Simplify smob and port marking; set the mark bit in the generic
- marking code, and make marker routines only responsible for
- turning up outgoing pointers.
- * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
- before calling the marking function. Don't call the marking
- function if it's zero.
- * markers.c (scm_mark0): Just return #f. This function isn't
- necessary at all now, but it's harmless to call it. We'll leave
- it in so other folks' code doesn't croak at link time.
- (scm_markcdr): Don't call SCM_SETGC8MARK.
- * async.c (mark_async): Don't call SCM_SETGC8MARK.
- * dynl.c (mark_dynl_obj): Same.
- * root.c (mark_root): Same.
- * srcprop.c (marksrcprops): Same.
- * unif.c (markra): Same.
- * variable.c (scm_markvar): Same.
- * ports.c (scm_markstream): Same.
- (void_port_ptob): Specify zero for our marking function.
- * debug.c (debugobjsmob): Same.
- * dynwind.c (guardsmob): Same.
- * filesys.c (dir_smob): Same.
- * fluids.c (fluid_smob): Same.
- * fports.c (scm_fptob, scm_pipob): Same.
- * mallocs.c (mallocsmob): Same.
- * regex-posix.c (regex_t_smob): Same.
- * smob.c (freecell, flob, bigob): Same.
- * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
- * throw.c (jbsmob, lazy_catch_funs): Same.
-
-1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * eval.c (scm_copy_tree): Reverted last change: `eval' uses
- scm_copy_tree on code in order not to let memoized code to leak
- out. Thus, scm_copy_tree needs to copy vectors as well since
- quasiquote can introduce evaluated code also inside vector
- constants.
-
-1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * eval.c (scm_copy_tree): Removed ability to copy vectors.
-
- * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
- gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
- gh_doubles2dvect.)
-
- * unif.c: Say that ivect and uvect are of type signed and unsigned
- long instead of int in commentary so that it correctly describes
- the implementation.
-
-1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
-
- * stime.c: Removed declaration of strptime. (It should be
- declared by the system headers. If it turns out that some systems
- don't, we'll handle that then.) (Thanks to Greg Troxel.)
-
- * stime.h: Renamed TIMEH --> STIMEH
-
- * backtrace.c (scm_display_error, scm_display_backtrace): In order
- to increase portability, don't use structure assignment.
- (Thanks to Nicolas Neuss.)
-
- * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
- portability.
- (finalize_fd_sets): Added empty statement after last case label.
- (Thanks to Nicolas Neuss.)
-
- * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
- Nicolas Neuss.)
-
-Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
-
- * init.c, readline.c: OK, I won't have these readline.x bug
- reports anymore. We've had them since April. The current reason
- is a completely unintelligible failure of totoro.red-bean.com to
- do the test for rl_getc_function in libreadline correctly. 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.

-
- * init.c (scm_boot_guile_1): Removed condition around

- * 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.)

-
- * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
- readline functions to come in release 2.3. (Thanks to Chet
- Ramey.)

-
-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.
-

- 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

-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.
-

-
-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

- (scm_catch): Don't accept a #f tag.
- (scm_throw): Check that key is a symbol.

-
-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. (Thanks to Harald Meland.)
-
- * filesys.c (scm_stat): Slightly optimized.
-
-Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
-
- * ports.c (scm_close_port): Make sure the port is open before
- trying to close it.
-
- * guile-snarf.in: Pass args through to gcc in a way that preserves
- whitespace boundaries. (Thanks to Greg Badros.)
-
-1997-12-02 Tim Pierce <twp@skepsis.com>
-
- * stacks.c (scm_frame_procedure): Reverse the logic in the return
- statement. (Thanks to Doug Evans for pointing this out.)
-
-1997-12-01 Tim Pierce <twp@skepsis.com>
-
- * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
-
-Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
-
- * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
- errno macro expansion of this field name. (errno is a C
- preprocessor macro on some systems.)
-
-1997-11-29 Tim Pierce <twp@skepsis.com>
-
- * iselect.c: Doc fix.
-
-Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>

- --> the_last_stack_fluid.
-
- * backtrace.c: Added #include "fluids.h"
- (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
- (scm_backtrace): `the-last-stack' is now a fluid.
-
- * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
- after scm_init_fluids.
-
-1997-11-28 Tim Pierce <twp@skepsis.com>
-
- * iselect.c: #ifdef USE_THREADS around thread-related includes.
-
- * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
- DLSYM_ADDS_USCORE to decide whether to add an underscore.
-
-1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * iselect.c (coop_next_runnable_thread,
- coop_wait_for_runnable_thread): Disable interrupts so that no
- async is executed before a potential error_revive.
- (scm_internal_select): Disable interrupts during the parts of the
- code which manipulate the sleep queue and the file descriptors.

- replacement in iselect.c.
- (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
- coop_join): If GUILE_ISELECT enabled, use
- coop_wait_for_runnable_thread instead of
- coop_next_runnable_thread.
- (usleep, sleep): New replacements for system functions if
- GUILE_ISELECT is enabled.
-
- * coop-threads.h: Declare coop_wait_for_runnable_thread.
-
- * coop-defs.h (coop_t): Added fields used by scm_internal_select.
-
- * filesys.c: Added #include "iselect.h". Moved FD-macros to
- iselect.h. Implement Scheme level `select' using
- scm_internal_select. (See NEWS.)
-
- * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
-
- * init.c: Call scm_init_iselect.
-
- * iselect.h, iselect.c: New files. Implements
- scm_internal_select. (See NEWS.)
-
-1997-11-27 Tim Pierce <twp@skepsis.com>
-
- Fix a memory leak in scm_read_line and a type cast bug in the ptob.
- * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
- and scm_must_free, since ultimately the string returned will be copied
- by scm_makfrom0str anyway. Also, read any characters that may have
- been pushed onto the port with scm_ungetc.
- * ports.c (scm_generic_fgets): Same as for scm_fgets.
- * ioext.c (scm_read_line): Free string after Guilifying it.
- * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
-
-1997-11-26 Anthony Green <green@hoser.cygnus.com>
-
- * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
-
- * gh.h: Safely wrap prototypes for c++ usage.
-
-1997-11-25 Mark Galassi <rosalia@cygnus.com>
-
- * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
- gh_repl (argc, argv).
-
-1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
-
- * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
- and to invoke scm_shell().
- (gh_launch_pad): took out the loading of boot-9.scm from here,
- since it is probably best to let the user control that. In fact,
- gh_repl() now invokes scm_shell() which does that.
-
-1997-11-23 Mark Galassi <rosalia@cygnus.com>
-
- * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
- invocation.
-
-1997-11-22 Tim Pierce <twp@twp.tezcat.com>
-
- * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by

-
- * regex-posix.c (scm_free_regex_t): Return size of regex_t instead

-
-1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
-
- * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
- configure.in was changed).

-Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
-
- * Makefile.am (modinclude_HEADERS): Include readline.h here.
- * Makefile.in: Regenerated.
-
-1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
-
- * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
- OPORT is an `open' port, not an output port.
-
- * filesys.c (scm_close, set_element, get_element, scm_chown,
- scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

- * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
- scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
- Likewise

- * backtrace.c (display_backtrace_body): Likewise
- * fports (scm_setvbuf): Likewise

- scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
- scm_getpeername, scm_send, scm_sendto): Likewise
- * unif.c (scm_uniform_array_write): Likewise
-

-
- Minor problems with substring-related tag changes.
- * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's

-
- * gh_test_c.c (c_vector_test): some improvements on the vector
- routines test.
-

- Now it (almost) does the right thing, though it takes a list
- instead of the individual arguments. I need to see how it could
- be done right.
- (gh_list_to_vector): added this function as a macro. Corresponds
- to Scheme's (list->vector ...).
- (gh_vector_to_list): added this function as a macro. Corresponds
- to Scheme's (vector->list ...).
-
- * gh_data.c (gh_vector_ref): renamed from gh_vref to

-
-1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>

-
- * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
- SCM_NIMP test before SCM_PRINT_STATE_P.

-
- * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
- (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
- If this slot contains a procedure, use that to print structures of
- the type represented by this vtable.
-
- * print.c (scm_iprin1): Don't print arguments of macro
- transformers. (They are always: exp env.); Bugfix: Unmemoize

- (cwdr_outer_body): Removed.
- (cwdr_handler): New function.
- (scm_internal_cwdr): New function to perform the function of cwdr
- but take args that are more useful to C code. Also, the handler
- is now invoked *outside* of the new dynamic root, like the docs
- say. We no longer have to catch absolutely all errors, the caller
- is responsible for using a handler that does not throw, if he
- wants that.
- (cwdr): Reimplemented in terms of scm_internal_cwdr.
- * root.h (scm_internal_cwdr): New prototype.
-
- Even more but risky streamlining:

- the JMPBUF of the scm_rootcont to NULL before returning.
-
- * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
- when they are non-NULL.
- (scm_gc_mark): Likewise, mark only when non-NULL.
-
- Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)

- a certain value is acceptable as a port argument.
- (scm_print_state_vtable): New variable.
- (scm_free_print_state): Set `revealed' field to false.
- (scm_iprin1): Call user supplied closure printer with
- scm_printer_apply. Print in the traditional way when there isn't
- one or when it returns #f.

-Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
-
- * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,

-
- * strports.c (scm_eval_string): Don't close the port.
-
- * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the

- Risacher.)
-
-Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
-
- * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
- makefile variable as a build parameter called LIBS. The
- build-guile program will use this, for the time being.
- * Makefile.in: Regenerated.
-
- Thanks to Shiro Kawai:
- * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
- * ports.h (scm_ptobfuns): The fgets method returns a char *, not
- an SCM.
-

-
- * script.c (scm_compile_shell_switches): If we hit the -c or --
- arguments, don't set the car of (command-line) to scm_usage_name,
- the prettified name of the guile executable; give it the full
- path, the way shells usually handle $0.
-
-Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
- Scheme-level name `array-map' and renamed `serial-array-map' to
- `serial-array-map!'.
-
- * backtrace.c: Introduced exception handlers which now enclose
- `display-error' and `display-backtrace' so that error reporting
- won't get into infinite loops if an error occurs during displaying
- of the error. This can very easily happen with user supplied
- print call-back routines.
-
-Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
- the names `serial-array-map' and `array-map' should be removed.)
-
-Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
-
- * init.c (scm_boot_guile_1): Added scm_init_objects ().

- (modinclude_HEADERS): Added objects.h.
-
- * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
- This test is needed at many places in the code and should be
- abstracted. (Motivated by the need of this test in libguiletk.)
-
- * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
- (scm_eval_string), load.c (scm_primitive_load,
- scm_read_and_eval_x), gh_eval.c (gh_eval_str):
- Use SCM_EOF_OBJECT_P.
-
- * eval.c (scm_init_eval): Add feature `delay'.

-
-Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * list.h (SCM_LISTn): New macros. Make list creation in C code
- prettier. The idea comes from STk.
-
- * sequences.h, sequences.c, append.h, append.c: Removed. These
- files implemented non-R4RS operations which would encourage
- non-portable programming style and less easy-to-read code.
-
- * Makefile.am (sequences.h, sequences.c, append.h, append.c):
- Removed.
-
- * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include

- (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
- `name'; Give names to macros as well.
-
- * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c

-
- * eval.c (macro?, macro-type, macro-name, macro-transformer): New
- procedures;
- (prinmacro): Removed. The code has been moved/merged into print.c
- in order to decrease code redundancy. We want macros to print in
- a way equivalent to procedures, and it would be silly to duplicate
- the required code. (We don't want to maintain two places.)
- (macrosmob): Print field is now a NULL pointer.
-
- * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
- scm_macro_transformer): New prototypes.
- (scm_tc16_macro): Declared.
-
- * print.c (scm_iprin1): Added code for printing of macros. Macros

- gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,

-
- * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
-
-Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * unif.c (scm_shap2ra): tighten the checking of the array dimension
- specifier, since (2) or (2 . 3) would cause SEGV.
- (scm_transpose_array): more argument checking fixes.
-
-Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>

-
-Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
-
- * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
- <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
- library.)
-

- ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
- unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

-
-Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * list.c (scm_list_append_x): Allow non-pair as last argument.
- This is consistent with the R4RS append and is probably the
- correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
-
-Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * stime.h: prototype for scm_times.
- * stime.c (scm_times): new procedure.
- * ioext.c (scm_fseek): if the first argument is a file descriptor
- call lseek.
- (scm_ftell): if the first argument is a file descriptor call lseek

- Add DEFER/ALLOW INTS to a few other procedures.
- (scm_fsync): new procedure.
- (scm_open_fdes): new procedure.
- (scm_open): use scm_open_fdes. If mode isn't specified, 666 will

- (scm_fcntl): the first argument can now be a file descriptor. The
- third argument is now optional.
-
- * posix.c (scm_execl, scm_execlp): make the filename argument

-
- * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
- (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
- argument to SCM_ASSERT. Furthermore, the name of the function
- should be passed as first argument when signalling
- SCM_WNA. (Thanks to Thomas Morgan)
-
- * gsubr.c (scm_gsubr_apply): From Radey Shouman
- <shouman@zianet.com>: "The switch in scm_gsubr_apply that
- dispatches on the number of actual args has a default case
- reporting an internal error. This is a vestige from a version
- that mallocated a SCM vector to hold the arguments. In the
- current version this check is too late: if it ever happens we will
- have already overstepped the bounds of the array.
-
- Also, the patch [...] adds a check for too many actual arguments."
-
- mdj: Removed check for "internal programming error".

-
- * ioext.h: removed scm_duplicate_port prototype.
-
- * ioext.c (scm_primitive_dup2): return the new file descriptor

- * dynl.c (scm_dynamic_link): Moved allocating of the memory for
- the dynamic object data below the linking of the object to avoid
- memory leak when the linking code throws an error. Now the code
- leaks a whole dynamically linked library when must_malloc throws,
- but that should be much less likely.
-
-Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>

- * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.

- uchars here.
- * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

- char.

- top of the word, it should be unsigned.
-
- * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
- is defined, to avoid warnings; it's only used in the
- conflict-checking code. Which might go away anyway.
- (SCM_CEVAL): All goto's targeting the `dispatch' label are in
- conditionals; put the label definition in an #if too, to stifle
- warnings.
-
- * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
- ChangeLog-threads in the distribution.
- * Makefile.in: Regenerated.
-

-
- * load.c (scm_init_load_path): Append $(datadir)/guile to

-
- * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
- 23:47:01 1997" changelog: Slots are now initialized with `#f' by
- default and not `()'. `#f' is the canonical non-value in Scheme,
- right?
-
-Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
-
- * struct.c (struct_printer): New variable that holds a handle on
- the Scheme variable *struct-printer*. This variable can be set by
- Scheme code to override the printing of structures.
- (scm_print_struct): If struct_printer is set, call it. If it is
- not set, or returns #f, print the structure in the old fashion.
- Include "eval.h" for scm_apply.
-
-Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
-
- * struct.c (scm_struct_ref, scm_struct_set_x): Use
- scm_struct_i_n_words to get the number of fields, not
- -scm_struct_n_extra_words.
-
- On the route to fancier struct printing:
- * struct.c (scm_print_struct): New function to print a structure.
- Include "genio.h" to support it. This function doesn't do
- anything interesting right now, but I think it should be here
- anyway.
- * struct.h: Include "print.h" and add prototype for
- scm_print_struct.
- * print.c (scm_iprin1): Call scm_print_struct instead of trying to
- print structures ourself.
-
-Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>

-
- * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
- loop.
-
- * posix.c (scm_uname): interpret only negative values as an error.
- Solaris normally returns a positive value.
-
- * script.c (scm_compile_shell_switches): if we are not going into
- an interactive repl, set scm_mask_ints to zero so that asyncs can
- run.
-
- * simpos.c (scm_system): don't ignore/unignore signals around
- the "system" call.
-
- * posix.c (scm_open_pipe): don't ignore/unignore signals around
- the "popen" call.
-
- * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
- done in boot-9.scm instead.
-
- * scmsigs.c, async.c: Major rewriting of signal handling code.
- (scm_sigaction): new procedure.
- (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
- timing.
- (scm_raise): return unspecified, throw error on failure.

- feature, to help boot-9.scm decide whether to import the regex
- module.
-
-Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * eval.c: Include scmconfig.h at the beginning of the file so that
- HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
- pointing this out.
-
- * regex-posix.c: #include "_scm.h" before conditionally #including
- <regex.h>; the former defines HAVE_REGCOMP.
-
- * regex-posix.c: #include <regex.h> conditionally, so the file is
- CPP'able (for dependency scanning) even on systems that don't have
- a <regex.h> header.
-
-Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- Add new R4RS-compliant syntax for keywords.
- * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
- regardless of the setting of the `keywords' read option.
- * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
- can be re-read no matter what the setting of the `keywords' read
- option.
-
-Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>

- Add support for POSIX regular expressions.
-
- * regex-posix.c, regex-posix.h: New files. (Some code

-
- * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
- Add regex-posix.[ch] sources.
- * Makefile.in: Regenerated.
-
- * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
- to do this automatically? It didn't for me, bleh.)
-
-Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * fports.c (print_pipe_port): New function.
- (scm_fptob): Use print_pipe_port instead of scm_prinport; the
- latter doesn't even take the right arguments.
-
- * Makefile.am: Increment shared lib revision number. I think
- sometimes the uninstalled Guile finds the installed shared lib;
- Gord says doing this might help. As things turned out, I can't
- say whether it does.
- * Makefile.in: Regenerated.
-
- * gh_init.c (gh_enter): Cast c_main_prog to a void * before
- passing it as the closure argument to scm_boot_guile. (Bill
- Janssen)
-
- * ports.c (print_void_port, putc_void_port, puts_void_port,
- write_void_port, flush_void_port, getc_void_port, close_void_port,
- noop0): Use ANSI prototypes instead of K&R declarations, so the
- initialization of void_port_ptob gets aggressively type-checked.
- Fix arguments of print_void_port and write_void_port. (Bill
- Janssen)
-
- * COPYING, __scm.h, _scm.h, alist.c, alist.h, append.c, append.h,

-Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * script.c (scm_find_executable): Use prototype-style definition
- here; apparently it's not quite right to have const in a prototype
- and then use a K&R declaration. I wonder if stuff like this will
- go away if we compile with -Wrequire-prototypes, or whatever that
- is... (Bernard URBAN)
-
- * scmhob.h: New text from Bernard URBAN.
-
-Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * script.c: Don't #define const on hpux. Configure takes care of
- this. (Thanks to Larry Schwimmer.)
-
- * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
- decide whether to #include <unistd.h>, instead of listing a bunch
- of systems. Don't #include stdio twice. Removed dyked-out
- definition of scm_find_impl_file.

- script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
- throw.c: Update copyright years; these files have been worked on
- significantly in 1997, but only had copyright years for 1996.
- Also, change name of copyright holder on some from Mikael
- Djurfeldt to Free Software Foundation; he has signed papers
- assigning the changes to the FSF.
-
- * script.c (scm_shell_usage): Pass FATAL to exit. There's no

- select, since they were not used in this file.
-
- * filesys.c (scm_select): make the fifth parameter microseconds,
- not milliseconds. let the fourth parameter be either a real value
- or an integer or #f. The first, second and third arguments can
- now be vectors: the type of the corresponding return set will be
- the same.
- (set_element, get_element): new static procedures.
-
-Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>

-
- From Tim Pierce:
- * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):

-
- * Makefile.in: Regenerated, using automake-1.1p.

- sure how this was supposed to work.
- (scm_async_click): don't send SCM_TICK_SIGNAL.
- (scm_init_async): don't initialize %tick-thunk.
-
- * the following change doesn't affect the Scheme interface:
- gc-thunk is called at the end of garbage collection. however it's
- no longer implemented by pretending it's a signal.
-
- * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
- system async corresponding to scm_gc_thunk.

-
- * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
- system has them. Hope this is safe. Previously
- sys/timeb.h was included if HAVE_FTIME was defined or if

- but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
-
- * ioext.c (scm_setfileno): add missing third argument to

- mean, generated mechanically, not self-generated. Hmm.))
- * guile.c, script.c, script.h: New source files.
- * init.c (scm_boot_guile_1): Call scm_init_script.

- values of cy_cv_threads_libs captures the libs chosen above.
- * Makefile.in, configure, aclocal.m4: Regenerated.
-
- * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.

-Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * backtrace.c (scm_backtrace): Split message string across

- gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
- New variables, describing how to build the gh test programs.
- * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
- build the test programs, and we probably should have been linking
- libguile.la against them all along, to support AIX shared libs.
- Add cflags for threads to CFLAGS; add libs for threads to new
- variable THREAD_LIBS, used in Makefile.am.
- * ChangeLog-gh: log from old `gh' subdirectory.
- * Makefile.in, configure, scmconfig.h.in: Rebuilt.
-
-Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * acconfig.h: Undo change of Apr 9; including the definition of
- PACKAGE in the guile headers conflicts with applications' own
- definitions.
- * scmconfig.h.in: Regenerated.
-
-Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

-
- * eval.c: Doc fixes.

-
- * stime.c (scm_init_stime): don't define ticks/sec.
- (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
- return value problem and is still portable.)

-Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid

- scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
-
- * posix.c (scm_mknod): split the mode argument into type and perms
- arguments, like the extra fields returned by stat.
-
- * fports.c (scm_pipob): set the close, free and print procedures.
- (scm_close_pipe): new procedure.
-
- * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,

-
-Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
- wan't defined. Don't include fd.h.
-
- * Previously fd.h was regenerated whenever configure was run,
- forcing a couple of files to be recompiled.
-
- * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
- * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
- Check for _fileno as well as _file.
- Don't output fd.h.
- * ioext.c: don't fd.h.
- * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
- other to FD_SETTER.
-
- * Change the stratigy for getting information about errno
- (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
- generating lists of symbols during the build process, which will
- not always work, include comprehensive lists in the distribution.
- To help keep the lists up to date, the "check_signals" and
- "check_errnos" make targets can be used.
-
- * configure.in: don't check for a command to extract errno codes.
- * Makefile.am: update file lists, remove errnos.list and errnos.c
- targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
- check_errnos targets.
- (CLEANFILES): remove errnos.c and errnos.list, add

- cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
- * errnos.default: deleted.
- * cpp_signal.c: new file.
- * cpp_errno.c: renamed from errnos_get.c.
- * cpp_err_symbols, cpp_sig_symbols: new files.
- * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
- * error.c (scm_init_error): #include cpp_err_symbols instead of
- errnos.c.
- * posix.c (scm_init_posix): don't intern signal symbols. #include
- cpp_sig_symbols.c.
-
-Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * strop.c (scm_i_index): allow the lower bound to be equal to the
- length of the string, so a null string doesn't always give an error.
-
- * posix.h: new prototypes.
- * posix.c (scm_status_exit_val, scm_status_term_sig,
- scm_status_stop_sig): new functions, as in scsh. They break down
- process status values as returned by waitpid.
-
-Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
- configure doesn't know about it.
-
-Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
-
- * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
- which defines C variables with global linkage.
-
-Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
- zero arg subrs.
-
-Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
-
- * eval.c (safe_setjmp): Temporarily use old setjmp until someone
- has time to check why this doesn't work well with continuations.
-
-Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
-
- * Fix shell syntax error; some shells won't tolerate
- multiple "fi" statements on a single line. (Thanks to Fred Fish.)
-
-Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * posix.c (scm_uname): throw an error if uname fails instead
- of returning errno.

-
- * error.c (err_head, scm_errno, scm_perror): obsolete procedures
- removed.

-
-Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * acconfig.h: Removed PACKAGE.
-
- * scmconfig.h.in: Regenerated.
-
- * snarf.h: g++ says it's non-portable not to specify the first
- argument in a varargs declaration. I introduced the first
- argument by using preprocessor conditionals.
-
-Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * ioext.c (scm_read_delimited_x): use RO string macros for delims.

- support for byte vectors.
-
- * print.c (scm_iprin1): Limit number of vector elements printed
- according to pstate->length.
-
-Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
-

- is an immediate.
-
- * error.h: prototype for scm_error_scm.
-
- * error.c (scm_error_scm): new procedure, reimplements scm-error
- in C and uses scm_error.
-
-Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
- pointer to the Scheme variable read-hash-procedures and intern it
- in scm_init_read. Modify scm_read_hash_extend and
- scm_get_hash_procedure to use the pointer.
-
-Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
- (SCM_KEYWORD_STYLE): defined.
-
- * read.c (scm_read_opts): add a keywords option. This isn't a
- boolean option, in case someone wants to add support for DSSSL
- keywords too.
- Setup scm_keyword_prefix symbol.
- (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
- set to 'prefix.
- I've left keyword support disabled by default, since it doesn't
- seem to break the module system and it gives R4RS standard behaviour.
- It can be reactivated with (read-set! keywords 'prefix).
-
-Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
- before constructing arbiter.

- closure before setting the procedure property!
-
- * ports.h: Removed prototype for scm_ungetc_char_ready_p.
-
- * ports.c: Removed `ungetc-char-ready?'.
-
-Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * read.c (scm_init_read): intitialise scm_read_hash_procedures
- (idea from Mikael: make it a pair so scm_permanent object only
- called once.)
- (scm_read_hash_extend): don't call scm_permanent_object.
- (ideas from Mikael): if chr is already in the list, replace its
- procedure instead of appending it again. If proc is #f, remove
- it from the list.
- (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
-
- * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
-
- * gdbint.c (gdb_read): update scm_lreadr usage.

-
- * read.h (SCM_N_READ_OPTIONS): increase to 3.
- (SCM_CASE_INSENSITIVE_P): define.
-
- * read.c: add case-insensitive option to scm_read_opts.
- (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
- to determine whether to convert symbol case.
- (default_case_i): definition removed.
- * read.c (scm_read_token): if case_i, downcase ic before doing
- anything with it.
-
-Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * configure.in: Added configuration option `guile-debug'.
- Configure with --enable-guile-debug if you want a bunch of extra
- functions used for debugging when developing Guile.
-
- * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
-
- * procs.c (make-cclo): New undocumented debugging procedure: Make
- compiled closure with internal procedure PROC and length LENGTH.
- Only compiled if GUILE_DEBUG is defined.
-
- * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
-
- * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
-
- * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
-
- * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
- with 3 or more args internally to the evaluator.
-
-Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
- with 3 or more args internally to the evaluator. This is mainly
- because we don't want to pass entry and exit points of the
- debug support twice, but it also seems to increase the speed of
- the evaluator for such calls (e. g. (+ 1 2 3)).
-
- * backtrace.c (scm_display_application): New procedure:
- display-application; Set fancy printing parameters individually
- for different types of display (backtrace, error, application).
- (These should of course be customizable!)
-
- * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
- clear the CHECK-flags.
-
-Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
-
-Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
- from pairs with a GLOC in the car.
-
- * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
- otherwise `symbol-hash' will behave badly.
- (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
- we get segmentation fault!
-
- * symbols.c: Added #include "weaks.h". New functions:
- `builtin-bindings' and `builtin-weak-bindings'. (These will be
- moved to an extraneous library when we split libguile.)
-
-Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * filesys.c (scm_stat): stat now takes fport arguments too as
- documented in the manual.
-
-Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * debug.c (scm_single_step): Bugfix: Call continuation with
- scm_call_continuation instead of throwing to it.
-
-Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
- argument wasn't declared to be optional.
-
-Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * stime.c (scm_init_stime): Add feature "current-time".
-
-Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * throw.h: prototype for scm_exit_status.
- * throw.c (scm_handle_by_message): if a 'quit is caught, use its
- args to derive an exit status. Allows (quit) to work from a
- script.
- (scm_exit_status): new function.
- #include "eq.h".
-
-Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * eval.c (scm_deval): Removed some old code.
- (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
- with the others.
- (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
- exit-frame traps.
-
- * symbols.c (msymbolize): Bugfix: Must initialize property list to
- SCM_EOL.
-
- * procs.c: Introduce the existent C function scm_thunk_p at the
- Scheme level as well.
-
-Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
- used from C to easily lookup the value of a symbol in the current
- module.
-
-Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * unif.c (scm_init_unif): Added #include "unif.x". (There are two
- scm_init_unif in this file. This will also fix a previous problem
- with guile-snarf.)
-
- * configure.in: Added AM_MAINTAINER_MODE
-
-Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
- avoid warnings.
-
-Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
-
- * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
- source files that are not always included in libguile but should
- have their dependencies calculated by automake. This variable is
- recognized by automake, no further magic is needed.
- (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
- to deal exclusively with *.lo files, as it seems. The *.o files
- are built automatically when the corresponding *.lo file gets
- built.
-
-Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * list.h (scm_list_cdr_ref): Delete prototype; function no longer
- exists.
-
-Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * unif.c (scm_array_set_x): minor change to argument error checking.
-
-Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
- inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
- They should only be included in the library at configure.in's
- discretion.
- (libguile_la_LDADD): Include the appropriate .lo files here.
- (libguile_la_DEPENDENCIES): List the corresponding .o files here,
- so we know when to build them (and their .lo bretheren).
- * configure.in (LIBLOBJS): New substituted variable. We let
- configure decide which .o files to include in LIBOBJS, and then
- put the corresponding list of .lo files in LIBLOBJS. The latter
- is what we pass to libtool.
- * Makefile.in, configure: regenerated.
-
-Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
-
- * symbols.c (scm_sysintern0): New function. Contains the core of
- old scm_sysintern but doesn't take a second value argument.
- (scm_sysintern): Now uses scm_sysintern0.
- (scm_sysintern_no_module_lookup): Renamed to
- scm_sysintern0_no_module_lookup and doesn't take a second value
- argument any longer.
-
- * symbols.h (scm_sysintern0: Added declaration.
-
- * options.c (scm_init_opts): Use scm_sysintern0 instead of
- scm_sysintern when interning option keys. Otherwise we risk
- destroying the values of already interned variables.
-
- * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
- scheme-level boolean (use SCM_NFALSEP).
-
- * backtrace.c (scm_init_backtrace): Make Scheme-level variable
- `the-last-stack'.
- (scm_backtrace): New function. (C version of old function from
- boot-9.scm) Motivation: Make it possible to display backtraces
- without depending on boot-9.scm. (I'm uncertain if this
- motivation is good enough...)
-
- * root.h (scm_root_state): Add member the_last_stack_var.
- (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
-
- * root.c (mark_root): Mark scm_the_last_stack_var.
-
- * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
- SCM_BOOL_F.
-
-Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
-
- * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
- 1. mark_lazy_catch didn't mark the smob.
- 2. Both functions above have standard variants:
- (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
- free_lazy_catch --> scm_free0.
-
-Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * throw.c (scm_internal_lazy_catch): New function.
- (scm_lazy_catch): Rewritten to use it.
- (scm_ithrow): Handle the new lazy catch representation.
- Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
- that doesn't have a jmpbuf is a lazy catch clause.
- (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
- free_lazy_catch, print_lazy_catch, lazy_catch_funs,
- make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
- smob.
- (scm_init_throw): Register the new lazy-catch smob type.
- * throw.h (scm_internal_lazy_catch): decl for new function.
-
- * throw.c (scm_internal_catch): Doc fixes.
-
- * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
- configure.in. Including this might cause problems if applications
- that link against libguile include their own copies of alloca, but
- if they're using autoconf, they should be adding libguile to LIBS
- before calling AC_FUNC_ALLOCA anyway, in which case they'll find
- the copy in libguile, and things will be okay. (I think.)
-
-Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
- unif.c.
- strop.h: move prototypes too.
-
-Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * posix.c (scm_init_posix): don't intern EINTR since it's now done
- elsewhere.
-
- * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
- etc. I deleted them from filesys.c long ago, but didn't
- notice they were here too (although ineffective since
- sys/stat.h wasn't included).
-
-Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
-
- * eval.c: Don't define alloca in GCC case. gcc will automatically
- use __builtin_alloca if appropriate.
-
-Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
-
- * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
- (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
- that values of automatic variables are preserved. See comments
- for safe_setjmp for details.
-
- Change from Thomas Morgan:

- (variable_smob): Use var_equal as the discriminator for variables.
-
- * throw.c (s_throw): Remove extraneous declaration.
-
- * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
- * eval.c: Add necessary CPP cruft to support that.
- * configure, Makefile.in, scmconfig.h.in: regenerated.
-
- Change from Thomas Morgan:
- * procprop.c (scm_procedure_properties): Convert the Scheme
- boolean returned by scm_procedure_p into a C boolean before using
- it as a condition for SCM_ASSERT.
- (scm_procedure_property): Likewise.
-
- * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
- indications of Unixness.
- * stime.c: Same.

-
-Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
-
- * read.c (scm_lreadr): use scm_misc_error to improve one of the
- "unknown # object" error messages.
-
- * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
- (scm_i_index) and declare it static. 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. Change the scheme names to
- recv! and recvfrom!. 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. Some of their functionality can be done without
- dynamic linking; when it's really needed, they throw errors.
-
-Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
-
- * configure.in: Only define DYNAMIC_LINKING when one of the system
- dependent functions is detected.
- * dynl.c (scm_dynamic_func): New function to get the address of a
- function in a dynamic object.
- (scm_dynamic_call, scm_dynamic_args_call): Accept the values
- produced by scm_dynamic_func as the thing to call.
-
-Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
-
- * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
- (scm_register_module_xxx, scm_registered_modules,
- scm_clear_registered_modules): New functions.
-
-Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
-
- * symbols.c (scm_sysintern): Renamed to
- scm_sysintern_no_module_lookup.
- (scm_sysintern): New function to take the place of the old
- scm_sysintern. 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. This function doesn't return a value;
- scm_boot_guile_1 doesn't return a value (or return at all).
-
- * eval.c (unmemocopy): Add a semicolon to appease the Sun
- compiler.
-
- * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
- compile. 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. In this case, we simply initialize the variables
- to placate the compiler, hopefully to a value which will cause a
- crash if it is ever actually used.
- * print.c (scm_iprin1): Initialize mw_pos.
- * read.c (scm_lreadrecparen): Initialize tl2, ans2.
- * throw.c (scm_ithrow): Initialize dynpair.
- * unif.c (scm_uniform_vector_ref): Initialize cra.
- * struct.c (init_struct): Initialize prot.
- * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
-
- * strports.c (scm_eval_0str): Don't return uninitialized garbage
- if EXPR contains no expressions.
-
-Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
- cause an infinite loop (???). So much for the algebraic
- equivalency of variable-sized arrays and alloca...
-
-Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
-
- * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
- a SCM boolean, not a C boolean.
-
-Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
-
- * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
- (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
- rules for raising scm_mtrigger. Previously, unfortunate but not
- unlikely circumstances could result in almost constant invokation
- of the gc. Now, this situations should be less likely, but they
- are not prevented completely.
-
-Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * numbers.c (scm_fuck): Procedure removed; looks like old test
- code.
- * numbers.h: Prototype removed.
-
-Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * debug.h (scm_debug_frame): Change `vect' member from an in-line
- array to a pointer, to match my Nov 21 change in eval.c.
-
-Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * libguile.h: Added #include "libguile/backtrace.h", #include
- "libguile/stacks.h".
-
- * strings.c (scm_string scm_make_string scm_string_ref
- scm_string_set_x scm_string_equal_p scm_string_append):
- Bugfix according to scm patch from Aubrey Jaffer:
- Corrected long-standing
- (not (eqv? (integer->char 128)
- (string-ref (make-string 1 (integer->char 128)) 0)))
- bug found by John Kozak <jk@noontide.demon.co.uk>.
-
- * strports.c, strports.h: Make scm_eval_0str return the value of
- the last expression evaluated (previously, it returned void).
-
- * strports.c, strports.h: New function: scm_read_0str. Does what
- it sounds like.
-
-Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * simpos.c (scm_getenv): return #f if string can't be found in the
- environment instead of throwing an exception, for compatibility
- with numerous other systems.
-
-Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
-
- * Makefile.am (.c.x): Use guile-snarf.

- executable.
- * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
-
-Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
-
- * backtrace.c (scm_display_error_message): Made non-static, and
- renamed from display_error_message.
- * backtrace.h (scm_display_error_message): Added extern decl.
- * throw.c (uncaught_throw): Use it to display the error message.
-
-Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
-
- * inet_aton.c: Use #if 0, not #ifdef 0.
-
-Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
- to convert the returned value.
- (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
- the offset argument.
-
-Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
-
- Add new interface to catch/throw, usable from C as well as
- Scheme.
- * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
- (scm_internal_catch): New function, replaces...
- (scm_catch_apply): Deleted.
- * throw.c (scm_catch_apply): Deleted; replaced with a more general
- mechanism which is a bit more code, but can be used nicely from C
- and implement the Scheme semantics as well.
- (scm_internal_catch): This is the replacement; it's named after
- the analogous function in Emacs.
- (scm_catch): Reimplemented in terms of the above.
- (struct catch_body_data, catch_body, catch_handler): New
- functions, used by scm_catch.
- * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
- (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
- support for new cwdr.
-
- * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed

-Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
-
- * acconfig.h: Added DYNAMIC_LINKING symbol.
- * configure.in: Add option and checks for dynamic linking.
- * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
- dynl.h: New files for dynamic linking support.
- * Makefile.am (libguile_a_SOURCES):
- Added "dynl.c".
- (modinclude_HEADERS): Added "dynl.h".
- (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
- "dynl-vms.c".
- * init.c (scm_boot_guile_1): Call
- scm_init_dynamic_linking to initialize dynamic linking support.
-
-Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
-
- * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
- (as we Schemers say). It needs to be global, so that I can tweak
- it for the proper operation of unexec.
- (scm_boot_guile_1_live): New variable, see above.
-
-Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
-
- * guile-snarf.sh: Removed.
- * PLUGIN/guile.libs: Added dependency for -lm.
- * acinclude.m4: Renamed from aclocal.m4.
- * PLUGIN/greet: Removed.
- * Makefile.am, aclocal.m4: New files.
- * configure.in: Updated for Automake.
-
-Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
-
- * eval.c (scm_definedp): Use top_level_lookup_closure_var
- and not top_level_lookup_thunk_var.
-
-Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
-
- * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
-
-Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
-
- * eval.c (scm_definedp): Incompatibly changed to be a builtin
- Scheme function, instead of syntax. Single argument is now a
- symbol.
-
-Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
- scm_ra_divide): Properly terminate statements passed as arguments
- to IVDEP macros. (Thanks to Bernard Urban.)
-
- * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
- with non-constant sizes. (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. (Thanks to Aubrey Jaffer.)
-
-Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
-
- * gc.c (struct scm_heap_seg_data): Doc fixes.
-
- * gc.c (scm_gc_sweep): Empty all segments' freelists before
- sweeping. Then, prepend each segment's free cells to its
- freelist, rather than wiping out the old value. (Thanks to Marius
- Vollmer.)
-
- * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
- scm_check_freelist, scm_debug_newcell): New functions and
- variables, for debugging freelist problems.
- * pairs.h (SCM_NEWCELL): New debugging version added.
- * gc.h (scm_debug_newcell): Added extern declaration, used by
- debugging version of SCM_NEWCELL.
-
-Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
-
- On some systems <libc.h> conflicts with <unistd.h>, and should not
- be #included at all.
- * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
- * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
- * configure.in: Call it.
- * posix.c, filesys.c: Use its results to decide whether or not to
- #include <libc.h>.
- * configure, scmconfig.h.in: Rebuilt with autoconf and
- autoheader.
-
-Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
- pointer to the stdio stream before calling scm_setbuf0, so the
- latter will be able to retrieve it. I'm surprised this didn't
- segfault earlier. (Thanks to Christopher Lee.)
-
-Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
- of `lazy-catch'.
-
-Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
-
- * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
- number of stack narrowing specifier pairs. 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. (Earlier, only closures were recorded.)
-
- * procprop.h: Added declaration of scm_i_name.
-
- * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
- (scm_make_gsubr): Record names of compiled closures.
-
-Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
-
- * debug.c, debug.h: Removed obsolete code.
-
- * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
- stacks.c: Renamed regs --> scm_contregs.
-
- * print.c (scm_free_print_state): Cleanup print state before
- returning it to pool. It is better to do it here than in
- scm_prin1 since scm_prin1 is called often.
-
- * srcprop.c (scm_source_properties, scm_set_source_properties_x,
- s_set_source_property_x): Check that first argument is a pair or a
- memoized object.
-
- * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
- scm_i_line, scm_i_column and scm_i_breakpoint global.
-
- * init.c: Added #include "backtrace.h" and #include "stacks.h".
- (scm_boot_guile_1): Added calls to scm_init_backtrace and
- scm_init_stacks.
-
- * debug.h: Added debug object smob declaration and macro
- definitions.
-
- * configure.in: Build with backtrace.o and stacks.o if debug
- support enabled.
-
- * Makefile.in: Added entries for new files: backtrace.c,
- backtrace.h, stacks.c and stacks.h.
-
- * symbols.c (scm_sym2ovcell): Fixed documentation.
-
- * _scm.h (min, max): Added.
-
- * async.c: Moved `min' macro to _scm.h.
-
- * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
- SCM_BACKTRACE_INDENT.
-
- * eval.c: Added new debug options `maxdepth' and `indent'.
-
- * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
-
- * print.h: Added selector SCM_PRINT_STATE.
-
- * print.c: New functions: scm_make_print_state,
- scm_free_print_state.
-
- * print.h: Added declarations for scm_make_print_state,
- scm_free_print_state.
-
- * debug.c (scm_m_start_stack): New acro.
-

-
- More prototype-related changes from Marius Vollmer:
- * gdb_interface.h: Wrapped header file in #ifdef/#endif
- * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
- * ports.h (ptobfuns): Added prototypes. This means some casting in

- are defined to take FILE * as their stream argument, not SCM.
- * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
- * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
- to `char *str_data' to conform to prototype.
-
-Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.

-
-Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
-

-
-Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
-

- (which is a list of argument lists, except for the tail) is a
- proper list, i.e., finite and terminated by '().
-
-Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * unif.c (scm_ra_set_contp): Localize `inc' declaration.
- Clarifies flow.
-
- * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
- symbolic name for the tag, scm_tc3_cons_gloc, instead of just
- saying "1".
-
- * vectors.c (scm_make_vector): Fill vectors with the undefined
- value, to help make Guile Scheme code more portable to other
- Schemes.
-
- * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.

- alone.
-
-Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
-
- * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
- `scm_init_threads'.
-
- * throw.h (scm_catch_apply): Removed the `lazyp' argument.
-
- * throw.c (scm_catch_apply): Finished implementation of
- `lazy-catch'.
-
-Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn

- * Makefile.in (root.o): Correct dependencies.
-
-Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
-
- * Makefile.in: Added dependency entry for root.o.
-
- * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
- throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
-
- * init.c (scm_start_stack): Set initial root continuation number
- to 0.
-
- * procs.c: New function: scm_thunk_p.
-
- * procs.h: Added declarations of scm_thunk_p.
-
- * root.c: Renamed `call-with-new-root' -->
- `call-with-dynamic-root'.
- (cwdr): Removed allocation of new root state. This should be done
- separately by use of scm_make_root.
- (scm_apply_with_dynamic_root): New function: Does what it
- sounds like. Needed when spawning threads.
-
- * root.h: Added member last_debug_frame to root state.
- Added #include "libguile/debug.h"
-
- * throw.c: Renamed scm_catch --> scm_catch_apply and added more
- arguments. The motivation is that code in root.c needs catch
- functionality, and we want to avoid code duplication.
- New functions: scm_catch, scm_lazy_catch. These are wrappers for
- scm_catch_apply. scm_lazy_catch is intended to introduce catch
- handlers that run without popping the stack into the dynwind
- chain.
-
- * throw.h: Added prototypes for scm_catch_apply and
- scm_lazy_catch.
-
-Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
-
- * root.h (scm_root, scm_set_root): Decouple thread support details
- by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
- SCM_SET_THREAD_LOCAL_DATA.
-
- * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
- and tortoise scanning loop.
-
-Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * Makefile.in: Rebuild dependencies.
-
- * libguile.h: #include "libguile/print.h" before "smob.h", since
- the latter uses the print_state structure.
-
- * throw.c (scm_ithrow): Use the correct variable when checking to
- see if a given element of scm_dynwinds is a valid catch.
-
- * throw.c (scm_ithrow): If scm_dynwinds has invalid list
- structure, abort; don't just silently ignore the garbage.
-
- * _scm.h: #include "print.h" here, since it seems to be used just
- about everywhere.
- * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
- strports.c, unif.h: Don't #include "print.h".
-
-Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
-
- * feature.h (scm_loc_features): Removed external declaration.

-
-Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
-
- * feature.c (scm_init_feature): Added threads feature (needs to be
- initialized here, since features doesn't exist when
- scm_init_threads is called).
-
- * libguile.h: Added #include "libguile/../threads/threads.h".
- (This is a kludge to get thread support working. This should be
- fixed.)
-
- * configure.in, acconfig.h: Added flags for thread support.
-
- * scmsigs.c: Define `signal' to be `pthread_signal' if using
- mit-pthreads.
-
- * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
- SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
- root.c:mark_root.
-
- * _scm.h: Added conditional #include "threads.h"
-
- * __scm.h (SCM_ASYNC_TICK): Added call to macro
- SCM_THREADS_SWITCHING_CODE.
-
- * init.c (scm_start_stack): Call `scm_make_root' to dynamically
- allocate the basic dynamic root object.
- (scm_boot_guile): Added call to scm_init_root.
-
- * root.c, root.h: Added root smob.
- (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
- functions: Implements dynamic roots mostly according to spec in
- SCM manual. Main difference is that the second argument is a
- throw handler rather than an error "thunk".
-
- * root.h: Added declaration of scm_init_root.
-
- * root.c: Added #include "genio.h", #include "smob.h", #include
- "pairs.h", #include "throw.h", #include "dynwind.h", #include
- "eval.h"
- (scm_init_root): Added #include "root.x".
-
- * throw.c: Added #include "stackchk.h"
- (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
- SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
- can be used in scm_call_with_new_root; Added reenabling of stack
- checking when catching a throw.
-
-Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>

-
- * list.c: Doc fixes throughout.
-
-Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
- declare the char * to be const. Avoids a warning in rgx.c.
-
- * ports.h: spelling fix.
-
- * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
- error messages.
-
- * load.c (scm_sys_try_load_path): throw an error if file not found
- (like it says it in NEWS).
-
-Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
- PROPS slot to '(), not #f; it's an empty alist.
-
- * throw.h, throw.c: Use SCM_P instead of #if hair.
-
- Remove special support for uncaught throws; see throw.c for
- rationale.
- * throw.c (uncaught_throw): New function.

- (scm_init_throw): Don't initialize it.
-
- * throw.c (scm_ithrow): Don't let outer key matches shadow inner

-
-Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * numbers.c (scm_istr2int): If the number is short (as most
- numbers are), just call scm_small_istr2int to deal with it.
- (scm_small_istr2int): New function, created by un-#ifdefing the
- non-bignum version of scm_istr2int and renaming it.
-
-Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * load.c (scm_sys_try_load): don't check whether value returned
- by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
- Change the Scheme name from %try-load to primitive-load.
-
- * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
- Can avoid passing a message, allowing it to be derived in the
- error handler (e.g., if we want to throw to the key both from
- Scheme and C).
-
-Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
-
- * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
- references now have a new appearance which is more compact and
- also gives a clue about what the target of the reference is.
- By setting parameters in the print state, more fancy printing can
- be achieved. This is used by the (not yet commited) backtrace
- code.
-
-Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
-
- * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include

-
- * init.c (scm_boot_guile): Moved scm_init_struct upwards so
- that it will be called before scm_init_print.
-
- * print.c (scm_prin1): Print states are now allocated when calling
- scm_prin1 and then passed around to all printing functions as an
- argument. A cache `print_state_pool' enables reuse of print
- states.
- (scm_make_print_state): New function.
- (scm_iprin1): Adaption to print states.
- (scm_iprlist): An initial "hare and tortoise" scan brings down
- time complexity to O (depth * N). (Better time complexity will be
- achieved when the printing code is completely rewritten.)
-
-Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
- AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
- it gets done whether or not the cache variable has a value.
-
-Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- Distinguish #f and ().
- * __scm.h: #undef SICP.
- * pairs.h (SCM_EOL): Delete this definition, equating it with
- SCM_BOOL_F.
- * tags.h (SCM_EOL): Give it a new definition here; I think I found
- the value it used to have. Doc fixes, too.
-
-Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
-
- * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
- scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
- Lord's implementation of structs, allowing for tail arrays as
- described in the manual. Also fixed some bugs. (Both the interface
- and the implementation should be improved.)
-
- * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
-
- * print.c, print.h: Closures now print like #<procedure foo (x)>.
- People who whish to see the source can do `(print-enable 'source)'.

-
- * stackchk.c (scm_report_stack_overflow): use lgh_error instead
- of scm_wta.
-
- * error.c, error.h: new error keys: scm_arg_type_key,

-
- * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
- object.
-

-
- * options.c: Documentation fixes.
-
- * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.

-
- * init.c (scm_boot_guile): Add level of indirection to
- scm_boot_guile_1() to ensure that stack base pointer is properly
- initialized. There was no guarantee that variable i was the
- highest/lowest variable on stack (i.e. the call frame of

-
-Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * ports.h (scm_port_table): put back file_name, it will be used to

-
- * print.c: Added code for detection of circular references during
- printing. (init_ref_stack, grow_ref_stack): New functions. 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.

-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>

- Missing declarations to functions in eval.c added.
-
- * filesys.c: Possibly uninitialized variable rv.

- 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.

- 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. Instead, get "__scm.h", "error.h", "pairs.h",

-
- * smob.h: #include "ports.h", "genio.h", and "print.h", since
- anyone who uses this file will need them to define the smob
- printing functions. Also, get markers.h, since people will need
- to #define the mark functions.
-
- * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
- * ports.h: ... to here.
-
- * ports.h (scm_port_table_size): Explicitly give type as 'int';
- don't rely on archaic C default type rules.
-
- * fports.h: #include "libguile/ports.h", since you need that in
- order to parse this.
-
- * genio.h: #include "libguile/print.h", because you need that to
- parse this; don't bother #including "ports.h", since print.h gets
- that.
-
- * error.h: Don't #include "pairs.h"; _scm.h will do that now.
-
- * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
- this; it's now a reference to an element of *scm_root.
-
- * debug.h: Don't #include "options.h"; the compiler won't be able
- to find that once the headers are installed; instead, #include

- * gc.h: Same, with marksweep.h.
- * mbstrings.h: Same, with symbols.h.
- * scmhob.h: Same, with _scm.h.
- * smob.h: Same, with params.h.
-
- * Makefile.in (depends): Don't nuke scmconfig.h and the generated
- C files; there's no need for this, and it forces recompilations
- unnecessarily.
-
-Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * error.c (scm_error): declare scm_error_callback.

- vports.h, weaks.h: #include "libguile/__scm.h", not
- <libguile/__scm.h>. This allows 'gcc -MM' to determine which
- dependencies are within libguile properly.
-
-Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
-
- * Makefile.in (.c.x): Simplify; there's no need to run this rule
- when scmconfig.h doesn't exist.
-
- * load.c (scm_sys_try_load): Correct spelling.
-
- * feature.c (scm_loc_features): Make this static.
-
- * Makefile.in (libpath.h): Omit trailing slash from path. We
- shouldn't require it of users, so why put it here?
-
- Move code to initialize and search %load-path from ice-9 to C
- code, so we can use the load-path to find the ice-9 boot code;
- this makes it easier to run Guile without installing it. See
- corresponding changes in guile/Makefile.in.
- * feature.c: Move stuff concerned with the load path to load.c.
- (scm_compiled_library_path): Deleted.
- Don't #include libpath.h here.
- * feature.h: Don't mention scm_compiled_library_path.
- * load.c: #include "libpath.h" here, as well as <sys/types.h>,
- <sys/stat.h>, and <unistd.h> (if present).
- (R_OK): #define if the system hasn't deigned to.
- (scm_loc_load_path): New variable.
- (scm_init_load_path, scm_sys_search_load_path,
- scm_sys_try_load_path): New functions.
- (scm_init_load): Initialize scm_loc_load_path to point to the
- value cell of the Scheme %load-path variable.
- * load.h: Add declarations for scm_sys_search_load_path,
- scm_sys_try_load_path.
- * init.c: Call scm_init_load_path.
- * Makefile.in (feature.o, load.o): Dependencies updated.
-
- * load.c, load.h: Rewrite using PROTO macro.
-
-Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
-
- * gc.c (scm_cellp): New function: C predicate to determine if an
- SCM value can be regarded as a pointer to a cell on the heap.
-
- * gc.h: Added declaration of scm_cellp.
-
- * gdb_interface.h: New file: The GDB interface header from the GDB
- distribution.
-
- * gdbint.c: New file: GDB interface.
-
- * gdbint.h: New file: GDB interface.
-
- * libguile.h: Added #include <libguile/gdbint.h>.
-
- * init.c (scm_boot_guile): Added scm_init_gdbint.
-
- * Makefile.in: Added gdb_interface.h, gdbint.[hc].
- Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
- found if object files and source are kept separate).
-
-Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
-
- * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
-
-Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * configure.in: Don't substitute the values of TCL_SRC_DIR and
- TK_SRC_DIR; they're not relevant any more.
-
- * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
- * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
-
-Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
-
- * PLUGIN/guile.config (xtra_cflags): Include .. in the header
- search path, so we can find the <libguile/MUMBLE.h> headers.
-
- * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
-
- * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
- implicit in the .c.o rule.
- (.c.x): Don't mention ALL_CFLAGS here; its value is included in
- $(CC) already.
-
- Put the library path in a header file, instead of passing it on
- the command line in every compilation.
- * Makefile.in (libpath.h): New target.
- (feature.o): Depend on libpath.h.
- (clean): Delete libpath.h.
- (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
- * feature.c: ... #include "libpath.h" here.
- * .cvsignore: Ignore libpath.h.
-
- Don't install the unwashed masses of Guile header files in the
- main #include path; put most of them in a subdirectory called
- 'libguile'. This avoids naming conflicts between Guile header
- files and system header files (of which there were a few).
- * Makefile.in (pkgincludedir): Deleted.
- (innerincludedir): New variable; this and $(includedir) are enough.
- (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
- (installed_h_files): Divide this up. Now this variable lists
- those header files which should go into $(includedir) (i.e. appear
- directly in the #include path), and ...
- (inner_h_files): ... this new variable says which files appear in
- a subdirectory, and are referred to as <libguile/mumble.h>.
- (h_files): List them both.
- (install): Create innerincludedir, not pkgincludedir. Put
- the installed_h_files and inner_h_files in their proper places.
- (uninstall): Corresponding changes.

- * __scm.h: Find scmconfig.h and tags.h in their new locations
- (they're both "inner" files).
-
-Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>

-
-Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * socket.c: Don't include a prototype for inet_aton; just use a
- K&R style declaration, to avoid warnings but minimize the chance
- of conflicts with the system.
-
- On NextStep, <utime.h> doesn't define struct utime, unless we
- #define _POSIX_SOURCE before #including it.

- testing for __EMX__.
-
- * posix.c: #include <libc.h>, if it exists.
-
- * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
- don't even know if the latter exists.

- s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
- s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
-
- * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
- header files don't.
- (scm_init_posix): Use them when initializing the Scheme constants
- of the same name.
-
-Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
-

- (install, uninstall): Put the header files in a special
- subdirectory, not in the main search path.
-
- * Makefile.in (ALL_CFLAGS): Provide the proper value for
- LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
-
- * Makefile.in (IMPLPATH): Deleted; never used.
-
- * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
- on the Tcl/Tk source any more.
- (INCLUDE_CFLAGS): Remove references to the above.
-
- * Makefile.in (version.o): Corrected dependencies.
-
-Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>

-
- * version.c: New file.
-
-Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * symbols.c (scm_strhash): scm_downcase is now a function, not an
- array; use it appropriately. Since GCC is quite happy to
- subscript functions, it never warned us about this; we should use
- -Wpointer-arith in the future. I guess we never tested
- case-insensitivity.
-
-Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>

-
- * strerror.c: new file from Emacs' sysdep.c.
- maybe configure should also check for sys_errlist.
-
- * configure.in (AC_REPLACE_FUNCS): add strerror.
-
-Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

-
- * continuations.c (scm_make_cont): Enlarged the #if 0 around
- scm_relocate_chunk_to_heap.
-
- * debug.c: New file: low-level debugging support. It also
- includes support for debugging with gdb. (The extensions to gdb
- are written by Per Bothner at Cygnus.)
-
- * debug.h: New file: low-level debugging support.
-
- * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
- argument pairs. Extensive modifications to the debugging
- evaluator. Added "SECTION:" commentaries to clarify what happens
- when, during double compilation. Renamed EVALIMP --> EVALIM.
- Renamed EVAL --> XEVAL. Removed function evalcar. Defined
- evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
- the beginning of the file. New procedure: scm_unmemocopy.
- Added some global state variables needed by the debugging
- evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,

-
- * libguile.h: Conditionally include debug.h
-
- * objprop.c (scm_object_properties, scm_set_object_properties_x):
- scm_object_properties shouldn't return handle. `handle' now gets
- initialized in scm_set_object_properties_x. scm_object_properties

-
-Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * libguile.h: #include "objprop.h"; I guess this was forgotten.
-
- * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
- and should be called by the final client.
-
-Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * gc.h: Use the PROTO macro when declaring functions.
- * gc.c: Use the PROTO macro when declaring static functions.
- Remove the CPP hair around function definitions.
-
- * gc.c (scm_init_storage): Initialize scm_asyncs.
-
- * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
- preprocessor symbol; "__scm.h" is where it might get #defined.
- * __scm.h: Similar: #include <scmconfig.h> before testing
- HAVE_LIMITS_H.
-
- * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
-
-Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * init.c (scm_boot_guile): Add init_func argument; call
- (*init_func) instead of calling scm_appinit; it's ucky to
- hard-code names for the user's procedures.
- * init.h (scm_boot_guile): Adjust declaration.
-
- * __scm.h (PROTO): New macro, for declaring functions with
- prototypes.
-
- * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
- eliminate all the __STDC__ conditionals.
- (scm_boot_guile): Add declaration.
- * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
- Remove __STDC__ conditionals around function definitions; the
- declarations in init.h will provide the same information, more
- usefully.
-
- * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
- complain about it in the error message; the error message is
- adequate without that note, and there's nothing the user can do
- about it.
-
-Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
-
- * Makefile.in (ancillary): Drop def.sed.
-
- * posix.c (scm_init_posix): Use numeric values, rather than
- CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
- F_OK. The symbols aren't available on some systems, and I'm
- pretty sure their values are fixed by common widespread practice.
- * ioext.c (scm_init_ioext): Code here defined them too; remove it.
-
- More functions unavailable on some systems.
- * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
- tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to

- * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
- scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
- bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
- stub that signals an error as the #else.
-
- * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
-
-Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>

-
- * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
- defined.
-
- * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
-
- * __scm.hd, def.sed: deleted.
-
-Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>

-
- * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.

-
- * Makefile.in (libobjs): Remove duplicate entry for markers.o.
-
- * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
- every if must have an else, or else the whole command has a
- non-zero exit code whenever the if's condition is false.
-
-Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
-
- * posix.c: include string.h.

- have been once.
-
- * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:

-
-Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
-
- * ports.c: removed functions relating to the mapping between ports
- and descriptors. (That stuff is unix-specific and should be collected

-
-Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>

-Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
-
- * ports.c (scm_add_to_port_table): Added fields

-Sun Aug 6 15:14:46 1995 Andrew McCallum <mccallum@vein.cs.rochester.edu>
-
- * guile.c (gscm_is_gscm_type): New function. (Without this how will we

-
- * variable.c (scm_variable_ref): fixed assertion test.
- (Robert STRANDH <strandh@labri.u-bordeaux.fr>)

+2000-01-09 Gary Houston <ghouston@arglist.com>
+
+ * These changes should make it unnecessary to call tzset from
+ Scheme after modifying the TZ environment variable, even if the
+ system date facilities cache the value.
+ * stime.c (setzone, scm_localtime): added comments.
+ (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
+ (setzone): don't call tzset.
+ (restorezone): call tzset only if HAVE_TZSET is defined.
+ (scm_tzset): don't define if HAVE_TZSET not defined. Change the
+ doc string to indicate that this procedure isn't likely to do
+ anything useful.
+ (scm_localtime, scm_strftime, scm_mktime): call tzset if
+ LOCALTIME_CACHE is defined.
+
+2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
+
+ * posix.c (scm_sync): Return SCM_UNSPECIFIED.
+
+2000-01-09 Gary Houston <ghouston@arglist.com>
+
+ * eval.c: define scm_unbound_variable_key ('unbound-variable).
+ scm_lookupcar1: throw an error with key 'unbound-variable instead
+ of 'misc-error when an unbound variable is encountered.
+
+ * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
+ scm_symlink, scm_readlink, scm_lstat),

+

+
+ * backtrace.c: Fix spelling typo in a comment.
+

+ text. Reformatted some of the expansions.
+
+Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
+ report the position of the argument.
+
+ * error.h, error.c (scm_out_of_range_pos): Added this function to
+ take extra "pos" argument, the position number of the errant
+ argument.
+
+ * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
+
+ * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
+ and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
+ prefers that and I'm reasonably indifferent.
+
+Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * snarf.h: Factor out differences between C++ and non-C++ into
+ SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
+ definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
+ Mikael's macros, below, but changed names and SCM_SNARFING no
+ longer expands to include %%% -- that must appear in the argument
+ so that the token appears at the call-site as a reminder).
+
+2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
+
+ * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
+ snarf macro definitions.
+
+2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * chars.c (scm_integer_to_char): Use Greg's nice
+ SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
+ adherence to R5RS.
+
+Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
+
+Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
+ instead of GUILE_PROC.
+
+Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * alist.c: Do not report mismatch errors on some uses of `tmp' (do
+ this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
+ macro call.
+
+Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
+
+ * scm_validate.h: Remove some redundant NIMP tests.
+
+ * alist.c: minimize scope of the tmp variables, and initialize
+ them when declared. The strange SCM_NIMP tests are replaced by
+ SCM_CONSP tests that more closely reflect the intended semantics.
+ However, we don't get a performance penalty here, because the
+ SCM_CONSP test was performed by the ALISTCELL test anyway. * The
+ extremely ugly use of ASRTGO macros was removed: The calls to
+ ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
+ label parameter that only exists when SCM_RECKLESS is not defined.
+ This works, because ASRTGO itself is defined in a way that it only
+ makes use of the label parameter if SCM_RECKLESS is not defined
+ (shudder!). Does guile make at all use of the possibility to
+ define SCM_RECKLESS? * Codesize is likely to be reduced, since
+ instead of two calls to SCM_ASSERT performed by the ALISTCELL test
+ we now only get one test.
+
+ * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
+ SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
+ some variables in `list?'. Fix `reverse' and `reverse!'
+ primitives to handle improper lists better.
+
+Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
+ macros and SCM_DEFINE macros to match GNU coding standards.
+
+Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
+
+Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
+ better consistency with the names of other SCM_VALIDATE_ macros
+ and better conformance to guile naming policy.
+
+Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
+ SCM_VALIDATE instead of 1 to avoid a check on the argument (since
+ it's not the actual name of the formal).
+
+ * guile-snarf.awk.in: Do argument/number mismatch checking and
+ print warnings in an Emacs compile-mode parseable format.
+
+ * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
+ SCM_OUTOFRANGE as 3rd argument.
+
+ * random.c: Fix argument/number mismatch (that I introduced :-( ).
+
+ * __scm.h: Do not #define SCM_ARG* when snarfing;
+ lets us distinguish between 1 and SCM_ARG1 when snarfing as only
+ the former (using the number) requires the argument to match the
+ formal in the current argument snarfing check.
+
+ * snarf.h: Give new definition of SCM_ASSERT when in
+ snarfing mode to output a lexically-identifiable sequence that the
+ guile-snarf.awk script uses to verify argument/position matching.
+
+ * ramap.c: Remove extraneous #undef FUNC_NAME.
+
+Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
+ current version of the same functionality; it writes the .x output
+ to stdout instead of directly into the file.
+
+Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
+ posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
+ redundant with the safer macros. Patch from Dirk Hermann applied
+ by hand. Thanks Dirk!
+
+ * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
+ uses in random.c.
+
+ * ramap.c: whitespace change.
+
+Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>

+ * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
+ removals from Dirk Hermann.
+
+ * alist.c: Rename formals to match the parameter names in the
+ documentation, updates to documentation. Thanks Dirk Hermann!
+
+2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * eval.c (SCM_CEVAL): Reverse order of
+ scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
+ (Thanks to Brad Knotwell.)
+
+Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
+
+ * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
+ allocated cell.
+
+ * pairs.h: Added a comment about the need for the SCM_SETCAR in
+ SCM_NEWCELL macro.
+
+Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
+
+ * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
+ SCM_NIMP tests that were redundant are now eliminated. Patches
+ from Dirk Hermann applied by hand.
