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.
error messages, not the uninitialized string `str'. Love that
typechecking.
* strop.c (scm_substring_move_x): New function, which can handle
arbitrary overlapping substrings.
(substring-move-left!, substring-move-right!): These are
now just synonyms for substring-move!.
* strop.h (scm_substring_move_x): New prototype.
(scm_substring_move_left_x, scm_substring_move_right_x):
#define these as synonyms for scm_substring_move_x.
functions; capitalize the first letter of each word in the
argument string, and downcase the rest.
(scm_string_ci_to_symbol): string->symbol, such that the same
symbol is returned for any argument where the only difference
between strings is in capitalization.
(scm_string_upcase, scm_string_downcase): non-destructive
versions.
* strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
changed to use memmove.
* strop.c (scm_i_index): removed the pos arguments (it's only
called twice, and each time it's SCM_ARG1, SCM_ARG2, SCM_ARG3,
SCM_ARG4).
* strop.h: fixed prototypes.
* * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
changed to have 5 required args, rather than 2 required, and 3 required
rest args. Also modified to allow str1 & str2 to overlap.
(scm_substring_fill_x): changed to 4 args, rather than 2 args and
2 required rest args.
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.
unif.c.
strop.h: move prototypes too.
* 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).
* 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.
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.
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.
strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
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.
