* libguile/ports.c (scm_c_make_port_with_encoding, scm_c_make_port): New
functions, to replace scm_new_port_table_entry. Use a weak set
instead of a weak table.
(scm_i_remove_port):
(scm_c_port_for_each, scm_port_for_each): Adapt to use weak set.
(scm_i_void_port): Use scm_c_make_port.
(scm_init_ports): Make a weak set.
* libguile/fports.c:
* libguile/ioext.c:
* libguile/r6rs-ports.c:
* libguile/strports.c:
* libguile/vports.c: Adapt to use the new scm_c_make_port API.
* libguile/bytevectors.h:
* libguile/bytevectors.c (scm_c_take_gc_bytevector): Rename this
internal function, from scm_c_take_bytevector. This indicates that
unlike the other scm_take_* functions, this one takes GC-managed
memory.
* libguile/objcodes.c (scm_objcode_to_bytecode):
* libguile/vm.c (really_make_boot_program): Use
scm_gc_malloc_pointerless, not scm_malloc. Thanks to Stefan
Israelsson Tampe!
* libguile/r6rs-ports.c:
* libguile/strings.c: Adapt to renames.
* libguile/inline.h (scm_get_byte_or_eof): Add `SCM_UNLIKELY' for EOF.
(scm_peek_byte_or_eof): New function.
* libguile/r6rs-ports.c (scm_lookahead_u8): Use `scm_peek_byte_or_eof'.
* libguile/bytevectors.h (SCM_BYTEVECTOR_HEADER_SIZE): Bump, giving
bytevectors another word: a parent pointer. Will allow for
sub-bytevectors and efficient mmap bindings.
* libguile/bytevectors.c (make_bytevector):
(make_bytevector_from_buffer): Init parent to #f.
(scm_c_take_bytevector, scm_c_take_typed_bytevector): Another
argument, the parent, which gets set in the bytevector.
* libguile/foreign.c (scm_pointer_to_bytevector): Use the parent field
instead of registering a weak reference from bytevector to foreign
pointer.
* libguile/objcodes.c (scm_objcode_to_bytecode): Use the parent field to
avoid copying the objcode.
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS):
* libguile/strings.c (scm_from_stringn):
* libguile/vm.c (really_make_boot_program):
* libguile/r6rs-ports.c (scm_get_bytevector_some)
(scm_get_bytevector_all, bytevector_output_port_procedure): Set the
parent to #f.
* libguile/r6rs-ports.c (bip_seek): Fix to allow seeking to end of port.
* test-suite/tests/r6rs-ports.test ("bytevector input port can seek to
very end"): Add tests.
* libguile/r6rs-ports.c (scm_get_string_n_x): Implement `get-string-n!'
in C for efficiency.
* libguile/r6rs-ports.h: Add prototype for this function.
* module/ice-9/binary-ports.scm: Export `get-string-n!'.
* module/rnrs/io/ports.scm (get-string-n): Implement based on
`get-string-n!'.
Export both `get-string-n!' and `get-string-n'.
* module/rnrs.scm: Also export these.
* test-suite/tests/r6rs-ports.test (8.2.9 Textual input): Add a few
tests for `get-string-n' and `get-string-n!'.

* libguile/r6rs-ports.c (make_bip, make_cbip, make_bop, make_cbop): Lock
the port table.
* libguile/r6rs-ports.c (make_bop): Let the returned extraction
procedure refer to the port's buffer instead of the port itself. This
fixes a segfault if the port is closed before the extraction procedure
is called.
(bop_proc_apply): Adapt accordingly.
* test-suite/tests/r6rs-ports.test (8.2.10 Output ports): Add testcase
for extraction after close.

* libguile/r6rs-ports.c (scm_register_r6rs_ports): New function.
* libguile/r6rs-ports.h (scm_register_r6rs_ports): New declaration.
* libguile/init.c (scm_i_init_guile): Call it.
Reported by Göran Weinholt <goran@weinholt.se>.
* libguile/r6rs-ports.c (scm_lookahead_u8): Return an unsigned byte.
* test-suite/tests/r6rs-ports.test ("7.2.8 Binary Input")["lookahead-u8:
result is unsigned"]: New test.
* libguile/gen-scmconfig.c (main): Produce a definition for
`scm_t_off'.
* libguile/ports.h (scm_t_port)[read_buf_size, saved_read_buf_size,
write_buf_size, seek, truncate]: Use `scm_t_off' instead of `off_t' so
that the layout and size of the structure does not depend on the
application's `_FILE_OFFSET_BITS' value. Reported by Bill
Schottstaedt, see
http://lists.gnu.org/archive/html/bug-guile/2009-06/msg00018.html.
(scm_set_port_seek, scm_set_port_truncate): Update.
* libguile/ports.c (scm_set_port_seek, scm_set_port_truncate): Use
`scm_t_off' and `off_t_or_off64_t'.
* libguile/fports.c (fport_seek, fport_truncate): Use `scm_t_off'
instead of `off_t'.
* libguile/r6rs-ports.c (bip_seek, cbp_seek, bop_seek): Use `scm_t_off'
instead of `off_t'.
* libguile/rw.c (scm_write_string_partial): Likewise.
* libguile/strports.c (st_resize_port, st_seek, st_truncate): Likewise.
* doc/ref/api-io.texi (Port Implementation): Update prototype of
`scm_set_port_seek ()' and `scm_set_port_truncate ()'.
* NEWS: Update.
* libguile/r6rs-ports.c (cbp_mark): A closed port will have had its
stream destroyed, so don't dereference the stream in that case. Patch by
Mike Gran.
