* module/web/response.scm (make-delimited-input-port)[close]: Replace
erroneous self-recursive call with a call to 'close-port'.
* test-suite/tests/web-response.test ("example-1")["response-body-port +
close"]: New test.
Reported by Panicz Maciej Godek <godek.maciek@gmail.com> in
<http://lists.gnu.org/archive/html/guile-user/2015-09/msg00017.html>.
* module/ice-9/psyntax.scm (match-each+): Fix the case where a non-pair
syntax object is encountered in a dotted tail.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/system/base/types.scm (cell->object): Use 'get-bytevector-n'
instead of 'get-bytevector-all', so that the zero-length case does not
return EOF.
* libguile/ports-internal.h (scm_port_buffer_position):
(scm_port_position_line, scm_port_position_set_line):
(scm_port_position_column, scm_port_position_set_column): New
helpers.
(scm_t_port): Ports now hold position as a pair, so that Scheme can
access it easily.
(SCM_LINUM, SCM_COL, SCM_INCLINE, SCM_ZEROCOL, SCM_INCCOL)
(SCM_DECCOL, SCM_TABCOL): Remove.
* libguile/ports.c (make_port_buffer): Rename from
scm_c_make_port_buffer, make static, and take port as an argument so
we can initialize the position field.
(initialize_port_buffers): Adapt make_port_buffer change.
(scm_c_make_port_with_encoding): Initialize position.
(update_port_position): Rename from update_port_lf, and operate on
port position objects.
(scm_ungetc): Operate on port position objects.
(scm_setvbuf, scm_expand_port_read_buffer_x): Adapt to
make_port_buffer change.
(scm_lfwrite): Adapt to call update_port_position.
(scm_port_line, scm_set_port_line_x, scm_port_column)
(scm_set_port_column_x): Adapt to use port positions.
* libguile/ports.h (scm_c_make_port_buffer): Remove internal decl.
* libguile/read.c: Adapt to use scm_port_line / scm_port_column instead
of SCM_LINUM et al.
* module/ice-9/ports.scm (port-buffer-position, port-position-line)
(port-position-column, set-port-position-line!)
(set-port-position-column!): New accessors for the internals module.
* module/ice-9/sports.scm (advance-port-position!): Rename from
port-advance-position! and use the new accessors.
(read-char, port-fold-chars/iso-8859-1): Adapt to use
advance-port-position!.
* libguile/ports.c (scm_specialize_port_encoding_x): Add some sanity
checks.
(scm_unget_bytes): Use scm_expand_port_read_buffer_x.
(port_clear_stream_start_for_bom_read): Use
scm_specialize_port_encoding_x.
(scm_fill_input): Use scm_expand_port_read_buffer_x.
(scm_expand_port_read_buffer_x): Rename from
scm_set_port_read_buffer_x and actually expand the buffer.
* libguile/ports.h: Adapt to scm_expand_port_read_buffer_x change.
* module/ice-9/ports.scm: Remove ports-in-scheme stuff, and instead
expose the ports internals via an auxiliary module. This will let
ports-in-scheme live in a module during Guile 2.2.
* module/ice-9/ports.scm (peek-bytes): New helper.
(peek-byte): Use peek-bytes helper.
(decoding-error): Don't inline; no need.
(decode-utf8, bad-utf8-len): New helpers.
(peek-char-and-len/utf8): Use new helpers.
(peek-char-and-len): No fast paths, and not inline. Peek-char has its
own fast path.
(%peek-char): Use helpers to make fast path.
* libguile/ports.c (scm_specialize_port_encoding_x)
(scm_port_clear_stream_start_for_bom_read): New functions exported
to (ice-9 ports).
* module/ice-9/ports.scm (clear-stream-start-for-bom-read):
(fill-input, peek-char-and-len): Rework to handle BOM in fill-input
instead of once per peek-char.
* module/ice-9/ports.scm: Speed tweaks to %peek-char. Ultimately
somewhat fruitless; I can get 1.4s instead of 1.5s by only
half-inlining the UTF-8 case though.
* module/ice-9/ports.scm (EILSEQ, decoding-error, peek-char-and-len/utf8):
(peek-char-and-len/iso-8859-1, peek-char-and-len/iconv):
(peek-char-and-len, %peek-char): New definitions. Missing iconv1 for
peek-char, but enough to benchmark.
* libguile/ports.h (scm_sys_port_encoding, scm_sys_set_port_encoding):
New functions, to expose port encodings as symbols directly to (ice-9
ports).
(scm_port_maybe_consume_initial_byte_order_mark): New function.
* libguile/ports.c (scm_port_encoding): Dispatch to %port-encoding.
(scm_set_port_encoding_x): Dispatch to %set-port-encoding!.
(port_maybe_consume_initial_byte_order_mark): New helper, factored out
of peek_codepoint.
(scm_port_maybe_consume_initial_byte_order_mark, peek_codepoint): Call
port_maybe_consume_initial_byte_order_mark.
* module/ice-9/ports.scm (port-encoding): Implement in Scheme.
* module/ice-9/ports.scm (fill-input): Rewrite to make changes like the
ones made to the C scm_fill_input: allow callers to specify a minimum
amount of buffering.
* libguile/ports.c (trampoline_to_c_read, trampoline_to_c_write): Since
C might assume that the indices are within bounds of the bytevector,
verify them more here.
(scm_port_random_access_p, scm_port_read_buffering)
(scm_set_port_read_buffer, scm_port_read, scm_port_write): New helpers
exposed to (ice-9 ports).
(scm_port_read_buffer, scm_port_write_buffer): Don't flush or validate
port mode; we do that in Scheme.
* module/ice-9/ports.scm: Implement enough of port machinery to
implement peek-byte in Scheme. Not yet exported.
* libguile/ports.c (scm_init_ice_9_ports): Define the-eof-object here.
Update a comment.
* module/ice-9/ports.scm: Use the-eof-object definition from C.
* module/ice-9/ports.scm: New file.
* am/bootstrap.am (SOURCES): Add ice-9/ports.scm.
* libguile/fports.c (scm_init_ice_9_fports): New function.
(scm_init_fports): Arrange for scm_init_ice_9_fports to be called via
load-extension, and load snarfed things there. Move open-file
definition early, to allow ports to bootstrap.
* libguile/ioext.c (scm_init_ice_9_ioext): New function.
(scm_init_ioext): Similarly, register scm_init_ice_9_ioext as an
extension.
* libguile/ports.c (scm_set_current_input_port)
(scm_set_current_output_port, scm_set_current_error_port): Don't
define Scheme bindings; do that in Scheme.
* libguile/ports.c (scm_i_set_default_port_encoding):
(scm_i_default_port_encoding, scm_i_default_port_conversion_handler):
(scm_i_set_default_port_conversion_handler): Since we now init
encoding early, remove the "init" flags on these encoding/strategy
vars.
(scm_init_ice_9_ports): New function.
(scm_init_ports): Register scm_init_ice_9_ports extension, and define
some bindings needed by the bootstrap.
* module/Makefile.am (SOURCES): Add ice-9/ports.scm.
* module/ice-9/boot-9.scm: Remove code that's not on the boot path,
moving it to ice-9/ports.scm. At the end, load (ice-9 ports).
* module/ice-9/psyntax.scm (include): Use close-port instead of
close-input-port.
* module/ice-9/psyntax-pp.scm (include): Regenerate.
* module/ice-9/r6rs-libraries.scm (resolve-r6rs-interface): In Guile, a
module's public interface is just another module, and that means that
it can import other modules as well. Allow for R6RS modules that
import module whose interfaces import other modules to access all
visible bindings.
* test-suite/tests/rnrs-libraries.test ("import features"): Update
test.
* module/ice-9/boot-9.scm (exception-printers): Fix error in which, for
a pure bootstrap with no compiled files, the exception printer would
use false-with-exception before it has been defined, which doesn't
work for macros. We wouldn't see this problem normally because,
oddly, the macro is indeed defined normally because of boot reasons.
* module/web/http.scm (make-chunked-output-port): Add #:buffering
argument, defaulting to 1200 (some random value under the MTU). This
will force a flush every so often, and not every character as would
otherwise be the case after this port rewrite.
* module/language/cps/types.scm (type-entry-saturating-union): Fix range
saturation in the negative direction. Previously we were artificially
truncating negative range ends to zero.
* module/statprof.scm: Remove most of the commentary, as it was
duplicated in the manual and was getting out of date.
(stats): Remove self-secs-per-call and cum-secs-per-call fields as
they can be computed from the other fields.
(statprof-call-data->stats): Adapt.
(statprof-stats-self-secs-per-call):
(statprof-stats-cum-secs-per-call): New functions.
(statprof-display/flat): Don't print the seconds-per-call fields, as
we are no longer stopping the clock around call counters. Anyway
these times were quite misleading.
(with-statprof): Deprecate. It took its keyword arguments at the
beginning; very complicated! Better to use the `statprof' function.
(`statprof' was introduced after `with-statprof' and then
`with-statprof' was adapted to use it.)
* doc/ref/statprof.texi (Statprof): Port this documentation away from
the automatically generated text and update it for the new interfaces
like #:display-style.
* module/system/base/syntax.scm (record-case): Remove comment that
referenced with-statprof. Add comment indicating that record-case
should be replaced.
* doc/ref/scheme-using.texi (Profile Commands): Update to mention
keyword arguments and to link to the statprof documentation.
* module/statprof.scm: Update commentary.
(count-call): Don't bother stopping and starting the timer. The
overhead of call counting perturbs timing too much already, and
somewhat paradoxically stopping and starting the timer takes too much
time.
(skip-count-call): New function.
(stack-samples->procedure-data, stack-samples->callee-lists): If we
are counting calls, skip any part of the stack that is inside
count-call.
* module/system/repl/debug.scm (print-locals): Adapt to
frame-binding-ref change.
* module/system/vm/frame.scm (<binding>): Add `frame' field.
(available-bindings): Capture the frame.
(binding-ref, binding-set!): New functions, accessing a local variable
value directly from a frame.
(frame-binding-ref, frame-binding-set!): Remove. As these are very
low-level debugging interfaces introduced in 2.0, never documented,
and quite tied to the VM, we feel comfortable making this change.
(frame-call-representation): Adapt to available-bindings change.
(frame-environment, frame-object-binding): Adapt to binding-ref
interface change.
* doc/ref/vm.texi (Stack Layout): Mention that slots can be re-used.
Update disassembly in example.
* doc/ref/api-debug.texi (Frames): Remove documentation for
frame-local-ref, frame-local-set!, and frame-num-locals. Replace with
documentation for frame-bindings, binding accessors, and binding-ref /
binding-set!.
* libguile/frames.h (scm_frame_num_locals, scm_frame_local_ref)
(scm_frame_local_set_x): Remove. As long as we are changing the
interface in a backward-incompatible way, we might as well remove
these.
* libguile/frames.c (scm_frame_num_locals, scm_frame_local_ref)
(scm_frame_local_set_x, scm_init_frames_builtins, scm_init_frames):
Arrange to make frame-local-ref et al private to frames.scm.
* module/system/vm/frame.scm: Load scm_init_frames_builtins extensions.
(frame-instruction-pointer-or-primitive-procedure-name): New public
function.
(frame-binding-ref, frame-binding-set!): Allow binding objects as
vars.
* module/system/repl/debug.scm (print-locals): Pass binding directly to
frame-binding-ref.
* module/statprof.scm (sample-stack-procs, count-call): Use new
frame-instruction-pointer-or-primitive-procedure-name function.
* module/system/vm/assembler.scm (define-byte-order-swapper): New
helper.
(byte-swap/2!, byte-swap/4!, byte-swap/8!): New functions.
(link-data): Swap bytes in uniform vectors on foreign byte orders.
