* error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
* strings.c (scm_string_ref): make the 2nd argument compulsory.
previously it defaulted to zero for no good reason that I can see.
use a local variable for SCM_INUM (k). replace
SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
(scm_makfromstr): cosmetic changes.
(scm_string): Accept only chars in the list, not strings, for
conformance to R5RS (particularly for list->string, which is
supposed to be the inverse of string->list.) remove
SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
scm_makstr handles the cell allocation. when reporting wrong-type
arg, don't report the position as 1.
* posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
* boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
to string-append.
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.
* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
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),
posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
scm_sync),
simpos.c (scm_system),
stime.c (scm_times, scm_strptime):
move the HAVE_XXX feature tests out of the procedure bodies.
don't use SCM_SYSMISSING.
scm_validate.h (SCM_SYSMISSING): removed.
error.h, error.c (scm_sysmissing): comment that this is deprecated.
see ChangeLog entry for 1999-12-28.
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.
GUILE_PROC1. Build guile-procedures.txt, and add that file to
pkgdata_DATA.
* load.c: Added `pkgdata-dir', `site-dir', `library-dir'
primitives.
* guile-doc-snarf.awk: Drop trailing space when no arguments:
e.g., "(foo )" is now "(foo)".
* *.c: moved all the documentation for primitives from
guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
This leaves about half of the primitives undocumented. Also, all
the markup is currently still texinfo. I don't have a problem
with texinfo per se, but the markup is not very descriptive or
accurate.
function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
* 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.
* 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.
* error.c: (various): use scm_cons instead of scm_listify
to build short lists.
* boot-9.scm (read-hash-extend to set up arrays): add 'l' for
long_long uniform vectors.
* networking.scm (sethostent, setnetent, setprotoent, setservent):
take an optional argument STAYOPEN. default is #f.
* readline.c (scm_init_readline): set rl_readline_name to Guile,
to allow conditionals in .inputrc.
scm_misc_error when pos is a string. This allows for dispatching
arbitrary error messages with one argument via SCM_ASSERT:
SCM_ASSERT (<cond>, obj, "Undigestable object: %S", <subr>);
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_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
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.
* 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.
primitives.
load errno.scm.
* netconst.scm: undefine maybe-define and maybe-define-so after use.
* errno.scm: new file.
* 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.

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.
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.
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).
integer (assuming for now accepting an integer is a good thing).
* error.c, fports.c: replace use of %S in lgh_error args with %s.
%S will be used instead for write'ing arguments.
* unif.c (scm_transpose_array): change arguments in the SCM_WNA
asserts. fix a few other asserts.
(scm_aind, scm_enclose_array, scm_array_in_bounds_p,
scm_uniform_vector_ref, scm_array_set_x,
scm_dimensions_to_unform_array): change args in
SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.

scm_substring_fill_x): likewise.
gsubr.c (scm_gsubr_apply): likewise.
eval.c (SCM_APPLY): likewise.
* eval.c (4 places): replace scm_everr with lgh_error or
scm_wrong_num_args.
* error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
scm_memory_error): new procedures.
* scm_everr: deleted. can use scm_wta, dropping first two args.
scm_error: convert NULL subr to SCM_BOOL_F.
* __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
SCM_ARGERR.
* stackchk.c (scm_report_stack_overflow): use lgh_error instead
of scm_wta.
* error.c, error.h: new error keys: scm_arg_type_key,
scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
scm_misc_error_key.
scm_wta: reimplement using lgh_error instead of scm_everr.
wta for range errors (ASSERT still needs work).
* error.c, error.h (scm_out_of_range): new procedure.
* error.c, error.h (scm_out_of_range_key): new key.
* posix.c (scm_sync): #else was missing.
* error.c, error.h: append _key to names scm_num_overflow and
scm_system_error.
* __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
of consing an empty list.
(SCM_SYSERROR etc.): move into error.c, make them procedures instead
of macros, saves code and string space.
error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
lower case. Rename scm_syserror_m to scm_syserror_msg.

"%%system-error".
* __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
* boot-9.scm: remove leading %% from references to '%%system-error.

aborting, just the key and subr.
Remove the code to "Install default handlers for built-in errors."
Remove the definition of the syserror procedure.
Associate 'numerical-overflow with default handler.
