* module/rnrs/io/ports.scm (&i/o-decoding, &i/o-encoding): Rename from
&i/o-decoding-error and &i/o-encoding-error, to conform to R6RS.

Subject: [PATCH] Hashtable-hash-function returns #f on eq and eqv tables.
* module/rnrs/hashtables.scm (r6rs:hashtable)[type]: New field.
(r6rs:hashtable-type): New procedure.
* test-suite/tests/r6rs-hashtables.test: Add related tests.
* module/rnrs/arithmetic/fixnums.scm (fxcopy-bit, fxbit-field)
(fxcopy-bit-field, fxarithmetic-shift)
(fxarithmetic-shift-left, fx-arithmetic-shift-right)
(fxrotate-bit-field, fxreverse-bit-field): Enforce range on amount by
which to shift. Fixes#14917.
* test-suite/tests/r6rs-arithmetic-fixnums.test ("fxarithmetic-shift-left"):
Update test to not shift left by a negative amount.
* module/language/tree-il/peval.scm (peval): Don't
inline (call-with-values foo (lambda (x) exp)) to (let ((x (foo)))
exp). The idea is that call-with-values sets up an explicit context
in which we are requesting an explicit return arity, and that dropping
extra values when there's not a rest argument is the wrong thing.
Fixes#13966.
* test-suite/tests/peval.test ("partial evaluation"): Update test.
* libguile/bytevectors.c (bytevector_large_set): Fix computation of
value size in words.
* test-suite/tests/bytevectors.test: Add test.
Thanks to Ben Rocer <fleabyte@mail.com> for the bug report and fix.
While describing special characters, remind the reader that
"non-greedy" variants are not supported. They might not be familiar
with POSIX extended regular expression and expect it to work.
* doc/ref/api-regex.texi: Add "non-greedy" observation
Linking to Emacs' regexps as an example of regexp syntax gives the
wrong impression that Guile supports it, which is not true.
* doc/ref/api-regex.texi: Remove link to Emacs' regexp syntax
* module/system/vm/assembler.scm (immediate-bits): Fix a bug whereby
compiling to a 32-bit target from a 64-bit host would treat all
integers whose representation fit into 32 bits as immediates. This
would result in integer constants between #x20000000 and 0x3fffffff
being residualized in such a way that they would be loaded as negative
numbers.
* libguile/load.c (load_thunk_from_path, try_load_thunk_from_file): New
functions.
(search_path): Simplify.
(scm_primitive_load_path, scm_init_eval_in_scheme): Use the new
functions to load compiled files.
* module/ice-9/boot-9.scm (load-in-vicinity): Skip invalid .go files.
Inspired by a patch from Jan Nieuwenhuizen <janneke@gnu.org>.
* libguile/vm-engine.c (SP_REF_SLOT, SP_SET_SLOT): New defines.
(push, pop, mov, long-mov): Move full slots. Fixes 32-bit with
unboxed 64-bit stack values; before when shuffling these values
around, we were only shuffling the lower 32 bits on 32-bit platforms.
* libguile/vm-engine.c (VM_VALIDATE): Refactor some type-related
assertions to use a common macro.
(vector-length, vector-set!/immediate): Fix the proc mentioned in the
error message.
* doc/ref/posix.texi (Network Sockets and Communication):
* libguile/socket.c (scm_accept): Return #f if the socket is nonblocking
and no connection is ready.
* libguile/ports.c (scm_port_encode_char): New function.
* module/ice-9/ports.scm (port-encode-char): Export port-encode-char to
the internals module.
* module/ice-9/sports.scm (put-char): New function.
(port-bindings): Add put-char and put-string.
* module/ice-9/suspendable-ports.scm: Rename from ice-9/sports.scm, and
adapt module names. Remove exports that are not related to the
suspendable ports facility; we want people to continue using the port
operations from their original locations. Add put-string to the
replacement list.
* module/Makefile.am: Adapt to rename.
* test-suite/tests/suspendable-ports.test: Rename from sports.test.
* test-suite/Makefile.am: Adapt to rename.
* module/ice-9/textual-ports.scm (unget-char, unget-string): New
functions.
* doc/ref/api-io.texi (Textual I/O, Simple Output): Flesh out
documentation.
(Line/Delimited): Undocument write-line, read-string, and
read-string!. This is handled by (ice-9 textual-ports).
(Bytevector Ports): Fix duplicated section.
(String Ports): Move the note about encodings down to the end.
(Custom Ports): Add explanatory text. Remove mention of C functions;
they should use the C port interface.
(Venerable Port Interfaces): Add text, and make documentation refer to
recommended interfaces.
(Using Ports from C): Add documentation.
(Non-Blocking I/O): Document more fully and adapt to suspendable-ports
name change.
* doc/ref/api-io.texi: Update to document ports more thoroughly. Still
some work needed.
* doc/ref/r6rs.texi: Move ports documentation back to r6rs.texi, now
that Guile has a more thorough binary/textual I/O story, heavily based
on R6RS.
* doc/ref/api-control.texi:
* doc/ref/api-data.texi:
* doc/ref/api-options.texi:
* doc/ref/misc-modules.texi:

* libguile/ports.c (scm_put_char): New function.
(scm_put_string): Add docstrings, and expose to the internal ports
module.
* module/ice-9/ports.scm (put-char, put-string): Expose these bindings
only through the internals module.
* libguile/socket.c (scm_init_socket): Define TCP_NODELAY and TCP_CORK
if they are available.
* doc/ref/posix.texi (Network Sockets and Communication): Add
documentation.
* NEWS: Add entry.
* module/ice-9/ports.scm: Export port-encode-chars and
port-clear-stream-start-for-bom-write via the internals module.
* module/ice-9/sports.scm (put-string): New function.
* libguile/ports.c (scm_port_clear_stream_start_for_bom_write): Instead
of returning the BOM, take an optional buffer in which to write the
BOM. Return number of bytes written.
(port_clear_stream_start_for_bom_write): Remove.
(scm_i_write): Adapt scm_port_clear_stream_start_for_bom_write call.
(try_encode_char_to_iconv_buf, encode_latin1_chars_to_latin1_buf):
(encode_latin1_chars_to_utf8_buf, encode_latin1_chars_to_iconv_buf):
(encode_latin1_chars, encode_utf32_chars_to_latin1_buf):
(encode_utf32_chars_to_utf8_buf, encode_utf32_chars_to_iconv_buf):
(encode_utf32_chars, port_encode_chars): New helpers.
(scm_port_encode_chars): New procedure.
(scm_c_put_latin1_chars, scm_c_put_utf32_chars): Rework to use new
encoding helpers.
(scm_lfwrite): Use scm_c_put_latin1_chars.
* libguile/print.c (iprin1): Use scm_c_put_string for strings.
* test-suite/test-suite/lib.scm (exception:encoding-error): Add an
additional expected error string for `encoding-error'.

(scm_c_put_char, scm_c_put_string, scm_print_string): New public
functions. The plan is to move encoding to ports.c and out of
print.c.
* libguile/ports.c (UTF8_BUFFER_SIZE, ESCAPE_BUFFER_SIZE): New internal
defines.
(update_port_position): Take a position instead of a port. Update
callers.
(utf8_to_codepoint): Allow lengths that are larger than necessary.
(port_clear_stream_start_for_bom_write): Require that io_mode be
BOM_IO_TEXT to write a BOM.
