so that test for the same function can be performed multiple
times.
* configure.in (AC_CHECK_HEADERS): Test for rxposix.h,
rx/rxposix.h. Add library rx only if regcomp can't be found
without it.
rx/rxposix.h. Add library rx only if regcomp can't be found
without it.
* acconfig.h (HAVE_REGCOMP): Added it here since autoheader misses
it for some reason!
non-false, send back results to Emacs; colnum: Column number;
Use modules (ice-9 debug) and (ice-9 session);
(no-stack, no-source): New simple-actions;
(result-to-emacs): New procedure. Sends data to Emacs via the
result protocol;
(get-frame-source, emacs-select-frame, emacs-frame-eval,
emacs-symdoc): New procedures.
* 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
(sic).
* filesys.h: prototypes for scm_open_fdes, scm_fsync.
* filesys.c (scm_chmod): if the first argument is a file descriptor,
call fchmod.
(scm_chown): if the first argument is a port or file descriptor,
call fchown.
(scm_truncate_file): new procedure.
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
now be used.
(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
compulsory, since omitting it causes SEGV.
(scm_sync): return unspecified instead of #f.
(scm_execle): new procedure.
(environ_list_to_c): new procedure.
(scm_environ): use environ_list_to_c. disable interrupts.
(scm_convert_exec_args): take pos and subr arguments and
improve error checking.
* boot-9.scm: define tms accessors: clock, utime, stime, cutime,
cstime.
primitive-load-path so that backtraces get narrowed properly at
the top.
* boot-9.scm (top-repl): Save stack already in signal handler in
order to narrow it correctly.
(save-stack): Adjust narrowing tag for the top of load-stacks.
(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)
<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".
throw.c (scm_internal_stack_catch): New sibling to the other catch
functions. Code moved from gh_eval.c.
throw.h: Added header.
gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
scm_internal_stack_catch.
* ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
Scheme name is now dup->fdes.
(scm_dup_to_fdes): make the second argument optional and
fold in the functionality of scm_primitive_dup.
(scm_primitive_dup): deleted.
* fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
* fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
ultrix are defined. Use setvbuf instead of setbuf.
(scm_setvbuf): new procedure.
(scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
(scm_setfileno): moved from ioext.c.
(scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
(top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
* boot-9.scm (move->fdes, dup->port): use dup->fdes, not primitive-dup.
(dup->fdes): deleted, now done in C.
