+
+ * 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.

+
+ * 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>

+ 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

+
+ * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.

+
+ * evalext.c (scm_serial_map): New procedure: Version of `map'

+
+ * evalext.h (scm_m_sequence_to_list): Added declaration.

+
+ * procs.c, procs.h (scm_procedure_documentation): Moved from

+
+ * init.c (scm_boot_guile_1): Added calls to scm_init_macros and

+
+ * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
+
+ * debug.c, print.c: Added #include "macros.h".
+
+1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
+
+ This change adds the ability to use `unread-char' multiple times
+ without interspersed reads and adds the new procedure
+ `unread-string'. The change is optimized for the common case of
+ unreading a single character. This is also the reason behind the
+ choice to store characters in the port itself: in most cases no
+ extra malloc is required.
+
+ The amount of code in some macros in ports.h has been increased to
+ the extent that they would fit better as C functions, but, since
+ this code belongs to the port representation, such functions
+ should be placed in ports.c which would cause calls back and forth
+ between ports.c and genio.c. That is not good for performance.
+ Also, keeping them as macros allows the compiler to do some
+ optimizations which are needed to make the current interface
+ (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
+
+ One benchmark (Guile startup time) indicates an increase of
+ loading speed of 1%. Another (reading (using `read') boot-9.scm
+ 10 times) shows no change in performance.
+
+ (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
+ made to find a beautiful solution.)
+
+ * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
+ (SCM_TRY_CLRDY): New macro: Only clear the first unread
+ character. (SCM_CLRDY clears all.)
+ (SCM_N_READY_CHARS): New macro: Returns number of unread
+ characters in a port. Returns wrong answer if SCM_CRDYP is false.
+ (struct scm_port_table): New fields: `entry' contains port table
+ index, `cp' points to last unread char, `cbuf' is the buffer for
+ unread chars, `cbufend' points after end of the character buffer.
+
+ * ports.h, ports.c (scm_unread_string): New procedure.
+ (scm_grow_port_cbuf): New function.
+
+ * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
+ Handle new fields.
+ (scm_generic_fgets), fports.c (local_fgets): Use a loop
+ to read unread characters. Use SCM_TRY_CLRDY instead of
+ SCM_CLRDY.
+
+ * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
+
+ * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
+
+ * genio.c, genio.h (scm_ungets): New function.
+
+ * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
+ sections.
+
+1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

+
+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>

+
+ 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.)

+
+ * unif.c (scm_raprin1): Changed print syntax for byte vectors from

+ 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

+
+1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

+ * struct.c (scm_struct_ref, scm_struct_set_x): Added

+ * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,

+ 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

+ (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 ->

+ 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

+
+ Don't redefine sleep and usleep; fix this problem now.
+ * coop.c (sleep, usleep): Remove declarations; we don't use or

+ 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

+ (sleep): Declare this, too, if the system hasn't.
+ (scm_sleep, scm_usleep): Use scm_thread_sleep and

+
+ The argument type of usleep varies from system to system,

+ knows what state the FILE * is in when we get it --- but it won't
+ do extraneous calls to fflush or fseek, so it's no worse than the
+ behavior before this change.
+ * ports.h: Add comment.
+
+ Centralize the creation of port objects based on stdio FILE * in
+ fports.c; don't just throw them together anywhere.
+ * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
+ what the rest of Guile wants. Don't set the revealed count;
+ that's only appropriate for stdin, stdout, stderr.
+ (scm_standard_stream_to_port): This function does set the revealed
+ count.
+ * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
+ not scm_stdio_to_port.
+ * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
+ * fports.c (scm_open_file): Same.
+ * posix.c (scm_pipe): Same.
+ * socket.c (scm_sock_fd_to_port): Same.
+ * ioext.c (scm_fdopen): Same.
+ (scm_freopen): Moved from here to...
+ * fports.c (scm_freopen): ... here. This is really something that
+ munges the internals of an fport, so it should go here.
+ * fports.h (scm_stdio_to_port): Adjust prototype.
+ (scm_standard_stream_to_port, scm_freopen): New protoypes.
+ * ioext.h (scm_freopen): Prototype removed.
+
+ * filesys.c (set_element, get_element): This can work on both pipe
+ and file ports, so use SCM_FPORTP to typecheck, instead of testing
+ for scm_tc16_fport.
+
+ * scmconfig.h.in: Regenerated.
+
+ Change the definition of the functions in scm_ptobfuns so that
+ they get passed the port object, not the port's stream.
+ * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
+ * gc.c (scm_gc_sweep): Pass the port itself to the free function.
+ * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
+ Pass the port itself to the scm_ptobs function.
+ * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
+ scm_generic_fgets): Same.
+ (putc_void_port, puts_void_port, write_void_port, flush_void_port,
+ getc_void_port, fgets_void_port, close_void_port): Just change the
+ argument names; these functions don't really do anything.
+ * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
+ local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
+ port as an argument, and use SCM_STREAM to get the stdio FILE *.
+ Also, use prototyped definitions, and get rid of the extra
+ declarations.
+ (scm_fptob, scm_pipob): We don't need casts here any more.
+ * strports.c (prinstpt): Use prototype declarations.
+ (stputc, stwrite, stputs, stgetc): Take the port as an argument,
+ and use SCM_STREAM to get the string info. Also, use prototyped
+ definitions, and get rid of the extra declarations.
+ * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
+ noop0): Same.
+
+ * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
+ prototype; it's okay (preferred, even!) to use ANSI C in Guile.
+
+ * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
+ scm_fgets, for consistency.
+ (scm_fptop, scm_pipob): References updated.
+
+1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ Include the source location in error messages for scripts.
+ * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
+ stack is still there when we catch the error.
+ * throw.c (handler_message): If we are handling an error with a
+ message, then put together the proper arguments and call
+ scm_display_error, instead of scm_display_error_message. That
+ displays source location, if it can find it.
+
+1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ * gc.c (scm_unprotect_object): Change this so that calls to
+ scm_protect_object and scm_unprotect_object nest properly.
+ (scm_protect_object): Doc fixes.
+
+ * strings.c (scm_string_set_x): Require the argument to be a
+ writable string, not a substring or a symbol.
+ * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
+ (Thanks to John Redford and Charbel Jacquin.)
+
+ * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
+
+1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
+
+ * eval.c (safe_setjmp): Remove this misunderstanding.
+ (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
+ ordinary setjmp.
+
+1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ * libguile.h: Mark these as C declarations, for compilation by C++
+ compilers.
+
+ * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
+ __cplusplus clause. I seriously doubt this ever worked the way
+ the author seems to have intended.
+
+1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ Utterly needless cleanups to hopelessly messy code.
+ * ports.c: Doc fixes.
+ (scm_fflush): Moved to ...
+ * genio.c (scm_fflush): ... here, amongst all the other port
+ method invocation functions.
+ * genio.h, ports.h: The prototype moves too.
+
+1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ * backtrace.c (display_error_body): The current frame does not
+ always have a parent frame; consider a function called directly
+ from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
+ Stachowiak.)
+
+ * alloca.c (alloca): Undo yesterday's changes, and simply call
+ malloc directly for storage, and abort if we don't get what we
+ want. The situation is much simpler --- just call malloc. Emacs
+ has bizarre/evil requirements (signal handlers might malloc unless
+ you set this global flag, so you have to set the flag around all
+ calls to malloc) which we are certainly not going to conform to,
+ so we can do the simple and obvious thing.
+
+ * coop.c (coop_condition_variable_wait): Make this function
+ static. It's only useful internally --- you should never just
+ wait on a condition variable.
+ * coop-defs.h (coop_condition_variable_wait): Delete prototype.
+
+1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ * unif.c (scm_array_set_x): Accept any kind of number as an
+ element for a uniform vector of doubles. This is more consistent
+ with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
+
+ * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
+ works; I can't conveniently test it myself. (Thanks to Dvid
+ Tillman for the bug report.)
+
+ * init.c: Doc fixes.
+
+ * init.c (invoke_main_func): Load the startup files (boot-9.scm)
+ from here, not from scm_compile_shell_switches (which is a pretty
+ dumb place to do it).
+ (scm_load_startup_files): New function.
+ (scm_ice_9_already_loaded): Variable moved to here from script.c.
+ * script.c (scm_compile_shell_switches): Don't load the startup
+ files here.
+ (scm_ice_9_already_loaded): Variable moved.
+ * init.c (scm_load_startup_files): Prototype for new function.
+ * gh_init.c (gh_enter): Doc fix.
+
+1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
+
+ Some anti-warning changes from Greg Harvey.
+ * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
+ warnings when it doesn't understand our NORETURN declarations in
+ error.h.
+ * posix.c (scm_mknod): Similar.
+
+1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ * posix.c (scm_getpwuid): If we can't find an entry, return our
+ own message, instead of using scm_syserror --- the getpwMUMBLE
+ functions don't set `errno' to anything interesting.
+
+1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
+
+ Get rid of warnings from the cooperative threading system.
+ * threads.h (scm_single_thread_p, scm_yield,
+ scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
+ scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
+ scm_wait_condition_variable, scm_signal_condition_variable): Add
+ prototypes for these Scheme-visible functions.
+ * coop-defs.h (coop_next_runnable_thread,
+ coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
+ Prototypes for these here, even though they're from iselect.c.
+ (coop_condition_variable_wait, coop_join): Add prototypes.
+ * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
+ scm_threads_free_condvar): Make these smob functions static.
+ * coop-threads.h (coop_init): Give this a real prototype.
+ * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
+ (coop_next_runnable_thread): No need to provide prototype; it's in
+ coop-defs.h.
+
+ * scmconfig.h.in: .detarenegeR
+
+ * iselect.c, threads.c: Doc fixes.
+
+1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ * Makefile.in: Regenerated with a patched automake, to get
+ dependency generation right when using EGCS.
+
+ * inet_aton.c (inet_aton): Add prototype, to remove compiler
+ warning. (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: Doc fix.
+ (rl_cleanup_after_signal, rl_free_line_state): Make these static.
+ * readline.h (scm_filename_completion_function): Add prototype.
+ (scm_init_readline): Make this into a prototype.
+
+ * 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.
+ (scm_init_readline): Make this a real prototype.
+
+1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ Warning fixes from Maciej Stachowiak:

+ * regex-posix.c (scm_regexp_error_msg): Make this function static.
+ * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
+ * root.h (scm_dynamic_root): Add external prototype.
+ * scmsigs.h (scm_usleep): Add external prototype.
+ * script.h (scm_init_script): Use prototype, not K&R decl.
+ * stacks.h (scm_stack_id): Add external prototype.
+ * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
+
+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>
+
+ * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
+ (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.
+
+ * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
+ avoid signed/unsigned comparisons.
+ * ports.h (scm_numptob): 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
+ debugging support unconditionally. That's backtrace.c, stack.c,
+ debug.c, and srcprop.c.
+ (EXTRA_libguile_la_SOURCES): Omit those from here.
+ * Makefile.in: Regenerated.
+
+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.
+ * eval.c (scm_eval_options_interface): Use prototype-style def'n.
+
+ * eval.c (scm_lookupcar1): Make this static.
+
+ * dynl.h (scm_registered_modules, scm_clear_registered_modules):
+ 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.
+ (scm_parse_path, scm_search_path): New Scheme level procedures.
+
+ * load.h (scm_internal_parse_path, scm_parse_path,
+ scm_search_path): Declared.
+
+1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * filesys.c (dirname, basename): New procedures.
+
+ * init.c (scm_boot_guile_1): Removed condition around
+ scm_init_options.
+
+ * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
+ new data type (guards) for representation of C level guards and
+ data on the wind chain.
+ (scm_internal_dynamic_wind): New function.
+
+ * dynwind.h: Declare scm_internal_dynamic_wind.
+
+ * root.h (scm_root_state): Added scm_cur_loadp.
+
+ * root.c (mark_root): Added comment about cur_loadp.
+
+ * load.c: #include "dynwind.h";
+ (scm_primitive_load): Use scm_inner_dynamic_wind to update
+ scm_cur_loadp.
+
+ * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
+

+
+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.

+
+1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
+
+ * debug.h, debug.c (scm_start_stack): New function. Implements
+ the guts of old scm_m_start_stack.
+
+ * debug.c (scm_m_start_stack): Use scm_start_stack.
+
+ * init.c (scm_start_stack, scm_restart_stack): Renamed to
+ start_stack and restart_stack. (These have static scope.)
+
+1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
+ readline functions to come in release 2.3. (Thanks to Chet
+ Ramey.)
+ (handle_errors): Use the above functions.
+
+1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * readline.c: Improvements for readline support: Handle errors
+ better; Implement before-read-hook.
+
+1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * init.c (scm_boot_guile_1), readline.c: Test for
+ HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
+ assure that we have version >= 2.1.)
+
+1998-05-11 Mikael Djurfeldt <mdj@kenneth>
+
+ * readline.c (scm_readline): Defer interrupts while we're calling
+ readline.
+
+ * readline.c (scm_add_history): Bugfix: Do strdup before giving
+ away the string to add_history.
+ (completion_function): Do completion for readline. (Thanks to
+ Andrew Archibald.)
+ (scm_filename_completion_function): New procedure: Filename
+ completer.
+ (current_input_getc): New function. Use this one instead of
+ standard getc from readline.
+
+ * throw.c, throw.h (scm_handle_by_throw): New function: This
+ handler throws errors to next handler on the dynwind chain.
+
+1998-05-09 Mikael Djurfeldt <mdj@kenneth>
+
+ * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
+ used.
+
+1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * procprop.c (scm_i_procedure_arity): New function. Returns arity
+ of procedure.
+ (scm_procedure_properties): Modified to return arity together with
+ other properties.
+ (scm_procedure_property): Added the read-only property `arity'.
+ (scm_set_procedure_property_x): It is an error to set the `arity'
+ property.
+
+ * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
+ prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
+
+ * procprop.h (scm_sym_arity): New symbol.
+
+ * objects.c (scm_set_object_procedure_x): New procedure: Use this
+ to set the dispatch procedure of an operator or entity object.
+
+ * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
+ Made procedure slots read-only.
+
+ * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above

+ construction for operators in scm_tcs_cons_gloc case in two args
+ switch.
+
+1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * fluids.c: Removed use of assert.h (in order to avoid
+ __eprintf).
+
+ * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
+
+ * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
+
+ * eval.c (SCM_CEVAL): Do more thorough argument checking. This
+ change makes the evaluator safer at the cost of evaluation speed.
+ It handles the case when the user has added a non-immediate
+ improper end of the application form, e.g., `(+ 0 . x)'.
+ (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
+ minimize the extra cost as much as possible. The new code is
+ enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
+ problem with structs planted directly in the code (e.g. by a
+ macro). This no longer causes segmentation fault. (Thanks to
+ Eric Hanchrow.)
+
+ * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
+ arg `proc' in order to be able to throw errors; New argument
+ checking code.
+
+ * Removed extra #include "debug.h"
+
+1998-04-25 Mikael Djurfeldt <mdj@kenneth>
+
+ * scmsigs.c: Declare usleep as returning void on some systems.
+ (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
+ Satchell.)
+
+ * coop.c (usleep): Return void on some systems.
+
+1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
+
+ * coop.c: Changed return type of usleep to int.
+
+ * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
+ isn't found in the OS.
+
+ * iselect.h: #define scm_internal_select select if GUILE_ISELECT
+ isn't enabled. (Thought that I had made this change ages ago...)
+
+ * iselect.c: Declare bzero if not defined by OS.
+
+1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
+ condition. (Thanks to John Tobey.)
+
+ * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
+ scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
+ A section.
+
+ * __scm.h: Start the long-term project of moving to POSIX threads.
+ Phase 1: Classification of all critical sections.
+ (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
+ for A sections. (See comments in __scm.h for details.)
+
+ * dynl.c: Only check that HAVE_DLOPEN is defined before loading
+ dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
+
+1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
+ cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
+ (libpath.h, versiondat.h): Replaced dependency on Makefile with
+ dependencies on $(srcdir)/Makefile.in
+ $(top_builddir)/config.status in order to avoid circularity.
+
+ * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
+ from argc if argc was 0 initially.
+
+ * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
+ in generation of libpath.h.
+
+1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
+
+ * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
+ libguile from 2 to 3.
+
+1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
+
+ * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
+
+1998-04-13 Mikael Djurfeldt <mdj@kenneth>
+
+ * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
+ scm_set_port_column_x, scm_port_filename,
+ scm_set_port_filename_x): Removed optional arguments. Added
+ proper argument checking.
+
+ * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
+ stack size in machine words.
+
+ * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
+ rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
+ to Ole Myren Röhne.)
+
+1998-04-12 Mikael Djurfeldt <mdj@kenneth>
+
+ * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
+ UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
+
+ * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
+ Caradoc-Davies.)
+
+ * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
+ procedure apply: Copy argument lists before pushing them unto the
+ environment so that the environment won't get mutated due to
+ manipulation of procedure arguments. This should perhaps be
+ regarded as a temporary solution until someone finds a more
+ efficient one. (Thanks to Maciej Stachowiak.)
+
+1998-04-10 Mikael Djurfeldt <mdj@kenneth>
+
+ * script.c (scm_compile_shell_switches): Use "guile" as default
+ zero arg if argc is NULL.
+
+1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
+

+
+1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
+
+ * ports.c (scm_add_to_port_table): First line is now line 0
+ (was 1). (Interface changed according to suggestion by Per
+ Bothner.)
+
+ * backtrace.c (display_header): Add 1 to line and column numbers
+ when presenting them to the user.
+
+ * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
+ from debug.c --> eval.c
+
+ * eval.h, eval.c (scm_eval_options_interface): New options
+ interface.
+ (SCM_EVAL_STACK): New option: Size of newly created stacks,
+ i.e. stacks for new threads.
+
+ * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
+
+ * eval.c (unsafe_setjmp): Removed with #if 0.
+
+ * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler

+ * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
+
+1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
+
+ * throw.c (handler_message): Print message on current error port
+ instead of default error port. (Thanks to Maciej Stachowiak.)
+
+Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
+
+ * ports.c (scm_add_to_port_table): allocate in units of
+ struct scm_port_table *, not struct scm_port_table.
+ * posix.c (scm_close_pipe): remove the port from the port table
+ and mark as closed.
+ Thanks to Rob Engle for both fixes.
+
+1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
+ coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
+
+1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * throw.h: Removed jmpbuf arg in scm_catch_body_t.
+
+ * backtrace.c (display_error_body, display_backtrace_body),
+ coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
+ gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
+ (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
+ scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
+ functions.
+
+ * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
+ don't receive the jmpbuf arg anylonger.
+ (scm_catch): Don't accept a #f tag.
+ (scm_throw): Check that key is a symbol.
+ (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
+
+Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
+
+ * async.c (async_pending): Removed declaration.
+
+1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * dynwind.c (scm_wind_chain): New debug function.
+
+ * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
+ scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
+ c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
+ extra layer of functions around the body and handler of a thread.
+ This extra layer makes sure that the handler is called in the
+ dynamic context of the surround (= empty dynwind list), but under
+ the *dynamic root* of the body. We can not use the dynamic root
+ of the surround since that root belongs to another thread => stack
+ is not handled correctly. It may seem ugly to use this extra
+ layer, but the extra cost in terms of execution time is really
+ negligible compared to the total amount of time required to create
+ a thread, and it would reduce maintainability to duplicate the
+ crucial and complicated steps performed by cwdr.
+
+ * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
+ (SCM_ALLOW_INTS): Added thread switching code before interrupts
+ get re-enabled. The important effect of this is that interrupts
+ are blocked during thread switching so that thread data structures
+ don't risk getting messed up by an unfortunate signal.
+ (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
+ seems to do more aggressive optimization which actually move
+ instructions around in these macros in a fatal way. Therefore:
+ Introduce Anthony's SCM_FENCE macro! (And I who thought he was
+ just superstitious...)
+ (SCM_TICK): Maybe do a context switch and take care of asyncs.
+ This macro should be used instead of SCM_ASYNC_TICK since the
+ latter doesn't do context switches any more.
+
+ * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
+ instead of SCM_ASYNC_TICK.
+
+ * coop.c, iselect.c: Since thread switches are now performed with
+ interrupts masked, we can't use the old mechanism of delivering
+ signals immediately when they arrive. Signals must instead be
+ delivered when the asyncs run *after* the end of the critical
+ section in scm_internal_select. But this also means after context
+ switch so that the signal will be delivered to a different thread.
+ To avoid this, I have changed the protocol of
+ coop_wait_for_runnable_thread and friends so that they are allowed
+ to return the original thread. So, if a signal arrives during
+ scm_internal_select, we won't any longer be forced do a context
+ switch, but can remain in the same thread and deliver the signal
+ to it.
+
+ * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
+ scm_asyncs_pending and made it global.
+
+ * iselect.c: Small fixes.
+
+ * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
+ coop_condition_variable_init, coop_condition_variable_wait,
+ coop_condition_variable_signal): Changed return type from `void'
+ to `int'. This is to adhere closer to the pthreads interface.
+ This, in turn, is part of an attempt to provide C versions of the
+ mutex and condition variable primitives which can be part of a
+ frontend to COOP or pthreads.
+
+ * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
+ coop_condition_variable_destroy): New functions.
+
+ * coop-threads.c (scm_wait_condition_variable): Use
+ coop_condition_variable_wait_mutex.
+
+ * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
+ Definitions moved to coop-defs.h.
+
+ * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
+ scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
+ scm_cond_destroy): New C interface to mutecis and cond vars.
+
+1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
+
+ * iselect.c: Now several threads can wait on the same file
+ descriptor. The behaviour is compatible with OS select: All
+ threads waiting for the fd return with the same status.
+
+1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * coop-threads.c, threads.h (scm_spawn_thread): New function.
+ Can spawn a thread from application C code.
+
+1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
+ gh_doubles2scm): New functions.
+
+1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
+
+ * gh_eval.c (gh_eval_str): cleanup -- threw out the old
+ commented-out version of gh_eval_str()
+
+Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
+
+ * socket.c (scm_bind): free soka after use.
+
+Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
+
+ * stime.c (tzvar): new variable.
+ (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
+ avoid memory leaks when allocating.
+
+1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
+
+ * iselect.h: Some systems require <sys/types.h> to get the FD_SET
+ macro definitions.
+
+ * gc.c, tags.h: Doc fixes.
+
+1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * eval.c (macro-eval!): Removed. This function was a design bug.
+ It allowed memoized code to leak out to the scheme level. Most
+ things that you could do with `macro-eval!' can be done with
+ `local-eval'.
+
+1997-12-20 Tim Pierce <twp@skepsis.com>
+
+ * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
+ scm_fgets now depends on ftell(3) to know how many bytes were
+ read. Sigh.
+
+1997-12-15 Tim Pierce <twp@skepsis.com>
+
+ * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
+ dealing with strings.
+
+1997-12-13 Tim Pierce <twp@skepsis.com>
+
+ Make %read-line more suitable for implementing read-line efficiently.
+ * ioext.c (scm_read_line): Strip the terminating newline from a
+ string, and return a cons of the string and its terminator.
+
+ * fports.c, fports.h (scm_fgets): Add `len' argument. The length
+ of the string that is read is stored in this memory location.
+ * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
+ * genio.c, genio.h (scm_do_read_line): Update caller.
+ * ports.h (scm_ptobfuns): Update typedef.
+ * fports.c (scm_fptob, scm_pipob): Update struct.
+
+1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * filesys.c (set_element): Return file descriptor.
+ (fill_select_type): Return the highest file descriptor.
+ (scm_select): Tell select about the highest file descriptor. On
+ some systems the SELECT_SET_SIZE can be as much as 128 bytes.
+ Therefore the extra overhead for calculating the maximum fd seems
+ to be more than compensated. Is this correct? In any case,
+ scm_internal_select will be much faster with this info.
+ (scm_select, fill_select_type, set_element): Don't accept any kind
+ of object in the file descriptor list or vector.
+
+1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * iselect.c (finalize_fd_sets): Bugfix.
+
+1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
+ when using scm_internal_select (since we might switch to another
+ thread).
+
+Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
+
+ * simpos.c (scm_system): always define: use sysmissing if not
+ available. Check for HAVE_SYSTEM instead of _Windows (does
+ Windows lack system or does it have an unusable one?).
+ Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
+ Let the argument be optional: if not supplied, call system(NULL).
+
+ * ports.c (scm_close_port): relax the type check from OPPORTP to
+ PORTP; closing a closed port is allowed.
+
+1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
+
+ * fports.c (scm_fgets): Return if the last char in a chunk is
+ newline. When fgets returns a string whose length is `size-1', it
+ is ambiguous whether a whole line was retrieved, so we must check
+ explicitly whether a line terminator is present.
+
+1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
+ before taking the CDR. (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>
+

+
+ * root.h (scm_root_state): Removed the_last_stack_var.
+
+ * throw.c: Added #include "fluids.h"
+ (ss_handler): `the-last-stack' is now a fluid.

+ * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
+ --> 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

+
+1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+
+ * iselect.c (coop_next_runnable_thread,

+ (scm_internal_select): Disable interrupts during the parts of the
+ code which manipulate the sleep queue and the file descriptors.
+
+1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

+ * coop-threads.h: Declare coop_wait_for_runnable_thread.
+
+ * coop-defs.h (coop_t): Added fields used by scm_internal_select.

+
+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.

+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.

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

+ (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

+ 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:

+ when they are non-NULL.
+ (scm_gc_mark): Likewise, mark only when non-NULL.

+ (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.
+ (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
+ Accept a port/print-state pair in addition to just a port.
+ (scm_prin1): Don't return the print_state to the pool when it has
+ been `revealed'.

+ * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
+ was looping endlessly.
+
+Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
+
+ * strports.c (scm_eval_string): Don't close the port.
+
+ * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
+ former returns a nice normal integer. (Thanks to Daniel
+ 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.)

+ (modinclude_HEADERS): Added objects.h.
+
+ * ports.h (SCM_EOF_OBJECT_P): New macro predicate.

+ (scm_eval_string), load.c (scm_primitive_load,
+ scm_read_and_eval_x), gh_eval.c (gh_eval_str):
