gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
gh_equal_p): Use SCM_NFALSEP, instead of testing against
SCM_BOOL_T. Any non-false value is true.
scm_gensym): Added prototypes.
* symbols.c (scm_gensym): New function. This will speed up
certain types of applications (such as macro systems) which
generate lots of symbols.
* 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.
(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.
state as nested data while they are printed.
(print_state_fluid, print_state_fluid_num): New variables.
(scm_init_print): Initialize them.
(scm_iprin): If print_state_fluid carries a print_state, use that
instead of creating a new one.
(scm_printer_apply, apply_stub, struct apply_data): New
definitions to help with calling printer functions written in
Scheme.
* print.h (scm_printer_apply): New prototype.
* ioext.c (scm_primitive_dup2): return the new file descriptor
instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
is convenient.
(scm_fdopen): bug fix: don't try to make port unbuffered until its
stream has been set.
(scm_duplicate_port): deleted, there's now an implementation in
boot-9.scm.
(scm_primitive_dup2): do nothing if newfd == oldfd.
* boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes,
dup, fdes->inport, fdes->outport, port->fdes): new procedures.
(duplicate-port): was a C primitive, now it's here.
(move->fdes): allow the first argument to be a file descriptor.
Return the modified port or file descriptor (was unspecified.)
SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
* ports.h: prototypes too.
* ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
* fports.h: prototype too.
* fports.c (scm_evict_ports): moved from ioext.c.
* ports.c (scm_close_port): return a boolean instead of unspecified.
throw an error if an error other than EBADF occurs.
* filesys.h: scm_close prototype.
* filesys.c (scm_close): new procedure, can close file descriptors
and ports (scsh compatible).
* ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
optional argument.
* root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
(scm_make_root): Call scm_copy_fluids to make fluid bindings
unique for the new root when it has a parent.
data. (dynl_smob): Use it.
* 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.
* stime.c (tzset): If tzset isn't provided, make it a NOP.
(scm_localtime): Change SCM_EOF to SCM_EOL.
(scm_mktime): Likewise.
* socket.c: Don't include sys/un.h unless autoconf tells
us Unix domain sockets are available.
(scm_fill_sockaddr): Ignore Unix domain code.
(scm_addr_vector): Likewise.
(scm_init_addr_buffer): Likewise.
(scm_socketpair): Don't include unless socketpair was
found during autoconf.
* simpos.c (SYSTNAME): Treat cygwin like Unix.
* scmsigs.c (scm_pause): Don't include unless pause was found
during autoconf.
* posix.c (scm_getgroups): Don't include unless support function
was found during autoconf (in this case, getgroups).
(scm_setpwent): For setpwent.
(scm_setegid): For setegid.
* net_db.c (scm_inet_netof): Don't include unless support
function was found during autoconf (in this case, inet_netof).
(scm_lnaof): For inet_lnaof.
(scm_inet_makeaddr): For inet_makeaddr.
(scm_getnet): For getnetent, getnetbyname, getnetbyaddr.
(scm_getproto): For getprotoent.
(scm_getserv): For getservent.
(scm_sethost): For sethostent, endhostent.
