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.
(scm_setnet): For setnetent, endnetent.
(scm_setproto): For setprotoent, endprotoent.
(scm_setserv): For setservent, endservent.
* scmconfig.h.in: Regenerated.
* configure.in: When sys/un.h exists, define HAVE_UNIX_DOMAIN_SOCKETS
to indicate that Unix domain sockets will work.
Check for socketpair, getgroups, setwent, pause, and tzset
(cygwin currently lacks these them).
Check for sethostent endhostent getnetent setnetent endnetent
getprotoent endprotoent getservent endservent getnetbyaddr
getnetbyname inet_lnaof inet_makeaddr inet_netof (cygwin currently
lacks them). In the case of cygwin, temporarily prefix these
functions with "cygwin32_", the way that netdb.h does.
Don't define HAVE_REGCOMP unless both regcomp and regex.h are
available (cygwin b18 came distributed without a working regex.h
file).
* acconfig.h (HAVE_UNIX_DOMAIN_SOCKETS): Add this.
* configure: Regenerated.
