* libguile/numbers.c (mem2ureal, left_shift_exact_integer,
floor_right_shift_exact_integer, round_right_shift_exact_integer):
Use 'assert' instead of 'scm_syserror' to indicate a case that should
never happen.
* libguile/numbers.c (scm_numerator, scm_denominator): Handle signed
zeroes and infinities in accordance with the corresponding R6RS flonum
procedures.
* module/rnrs/arithmetic/flonums.scm (flnumerator, fldenominator):
Remove special handling of infinities.
* test-suite/tests/numbers.test (numerator, denominator): Add tests.
Convert existing tests to use 'pass-if-equal'.
* test-suite/tests/r6rs-arithmetic-flonums.test (flnumerator): Fix
broken test of (flnumerator -0.0).
* libguile/numbers.c (double_is_non_negative_zero): Remove.
(idbl2str, scm_max, scm_min, scm_angle, log_of_shifted_double,
scm_log10): Use 'copysign' to check signs of zeroes,
instead of 'double_is_non_negative_zero'.
* libguile/vm-i-scheme.c (ASM_ADD): Remove the tag from one of the
operands before adding, to avoid overflow when the result is the most
positive fixnum.
Fixes <http://bugs.gnu.org/14905>.
Reported by Göran Weinholt <goran@weinholt.se>.
* libguile/numbers.c (scm_rationalize): Rewrite. Previously an
incorrect algorithm was used which failed in many cases.
* test-suite/tests/numbers.test (rationalize): Add tests.
* libguile/tags.h (SCM_UNPACK): Change (*(SCM*)0=(x)) to
(*(volatile SCM *)0=(x)), to avoid null-dereference warnings
from clang. Reported by Shane Celis <shane.celis@gmail.com>.
* libguile/numbers.c (scm_num_eq_p): Fix bug comparing fractions to
infinities (reported by Göran Weinholt <goran@weinholt.se>). Fix
erroneous comment describing the logic behind inum/flonum comparison.
Use similar logic for inum/complex comparison to avoid rounding
errors. Make minor indentation fixes and simplifications.
* test-suite/tests/numbers.test (=): Add tests.
* libguile/numbers.c (INUM_LOSSLESSLY_CONVERTIBLE_TO_DOUBLE):
New macro.
(scm_i_divide2double): Use INUM_LOSSLESSLY_CONVERTIBLE_TO_DOUBLE to
determine if our fast path is safe. Previously, negative arguments
were not checked properly.
* test-suite/tests/numbers.test (exact->inexact): Add tests.
Fixes <http://bugs.gnu.org/14864>.
Reported by Göran Weinholt <goran@weinholt.se>.
* libguile/vm-i-scheme.c (ash): Fallback to 'scm_ash' for right shifts
with counts >= SCM_I_FIXNUM_BIT, since '>>' is not guaranteed to work
correctly for large counts.
Reported and debugged by Andrew Gaylard <ag@computer.org>.
* libguile/threads.c (remqueue): When removing the last element from a
queue with more than one element, set (car q) to the previous element.
* THANKS: Thank Andrew Gaylard.

Based on a patch by Nala Ginrut <nalaginrut@gmail.com>
* libguile/threads.c (scm_unlock_mutex_timed): If 'timeout' argument
is false, interpret that as no timeout.
* doc/ref/api-scheduling.texi (Mutexes and Condition Variables):
Update documentation.
Reported by Mark H. Weaver.
* libguile/keywords.c (scm_c_bind_keyword_arguments): Use
`scm_error_scm' instead of `scm_error'. Pass the faulty keyword
enclosed in a list as the last argument.
* test-suite/tests/optargs.test ("scm_c_bind_keyword_arguments"): New
test prefix.
* libguile/vm.c (vm_error_kwargs_invalid_keyword,
vm_error_kwargs_unrecognized_keyword): Add parameter. Pass it
enclosed in a list as the last argument to `scm_error_scm'.
* libguile/vm-i-system.c (bind_kwargs): Adjust accordingly.
* libguile/eval.c (error_invalid_keyword, error_unrecognized_keyword):
Add parameter.
(prepare_boot_closure_env_for_apply): Adjust accordingly.
* module/ice-9/eval.scm (primitive-eval): Likewise.
* libguile/error.c (scm_error_scm): Mention `keyword-argument-error' in
docstring.
* module/ice-9/boot-9.scm (keyword-error-printer): New procedure; use it.
* test-suite/tests/optargs.test (c&e, with-test-prefix/c&e): Remove.
("define*")["unrecognized keyword"]: Test the value passed along the
`keyword-argument-error' exception.
["invalid keyword"]: New test.
* doc/ref/api-control.texi (Error Reporting): Update `scm-error'
description.
* libguile/stime.c: Remove #ifdef HAVE_SYS_TIMES_H, HAVE_SYS_TYPES_H,
and HAVE_STRING_H since those headers are always provided by Gnulib
when the corresponding macro is undefined. Fixes a regression on
MinGW introduced by commit 40e2a31.
* libguile/stime.c (scm_init_stime): Fix previous patch. At this point
in the source, we definitely have a run-time function, but don't
necessarily have a real-time function.
* configure.ac: Remove checks for pipe, stftime, times, and select, as
our Gnulib modules already ensure they are provided.
* libguile/stime.c: Rely on gnulib providing `times'.
* libguile/filesys.c (scm_sendfile): In Linux-style sendfile(2) code, if
EINTR or EAGAIN occurs, set result to 1 (not 0) so that we actually
keep going. In non-sendfile(2) code, deal gracefully with short reads
due to EOF.
* test-suite/tests/filesys.test ("sendfile"): Use 'let*' to guarantee
the needed order of operations: write (test-file) and then read it.
Add code to check the written data (not just the returned length) in
all tests, including the cases that hit EOF prematurely.
* libguile/filesys.c (scm_sendfile)[HAVE_SYS_SENDFILE_H &&
HAVE_SENDFILE]: Compare RESULT with C_COUNT. Loop until C_COUNT bytes
have been sent.

new semantics.
* test-suite/tests/filesys.test ("sendfile"): Rewrite using
`pass-if-equal'. Check the return value for all the tests.
["file with offset past the end", "file with offset near the end"]:
New tests.
* libguile/fports.c (scm_open_file_with_encoding): New API function,
containing the code previously found in 'scm_open_file', but modified
to accept the new 'guess_encoding' and 'encoding' arguments.
(scm_open_file): Now just a simple wrapper that calls
'scm_open_file_with_encoding'.
(scm_i_open_file): New implementation of 'open-file' that accepts
keyword arguments '#:guess-encoding' and '#:encoding', and calls
'scm_open_file_with_encoding'.
(scm_init_fports_keywords): New initialization function that gets
called after keywords are initialized.
* libguile/fports.h (scm_open_file_with_encoding,
scm_init_fports_keywords): Add prototypes.
* libguile/init.c (scm_i_init_guile): Call 'scm_init_fports_keywords'.
* module/ice-9/boot-9.scm: Add enhanced versions of 'open-input-file',
'open-output-file', 'call-with-input-file', 'call-with-output-file',
'with-input-from-file', 'with-output-to-file', and
'with-error-to-file', that accept keyword arguments '#:binary',
'#:encoding', and (for input port constructors) '#:guess-encoding'.
* doc/ref/api-io.texi (File Ports): Update documentation.
* test-suite/tests/ports.test ("keyword arguments for file openers"):
Add tests.
* libguile/ports.c (scm_i_unget_bytes): New static function.

* libguile/ports.h: Add prototype for 'scm_unget_bytes'.
* libguile/fports.c (scm_setvbuf): Use 'scm_unget_bytes'.
* libguile/r6rs-ports.c (scm_unget_bytevector): New procedure.
* module/ice-9/binary-ports.scm (unget-bytevector): New export.
* doc/ref/api-io.texi (R6RS Binary Input): Add documentation.
(R6RS I/O Ports): Update brief description of (ice-9 binary-ports) to
reflect the new reality: it is no longer a subset of (rnrs io ports).
* test-suite/tests/ports.test ("unget-bytevector"): Add test.
* libguile/fports.c (scm_open_file): Do not scan for coding
declarations. Replace 'use_encoding' local variable with
'binary'. Update documentation string.
* module/ice-9/psyntax.scm (include): Add the same file-encoding
logic that's used in compile-file and scm_primitive_load.
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/api-io.texi (File Ports): Update docs.
* test-suite/tests/ports.test: Change "open-file HONORS file coding
declarations" test to "open-file IGNORES file coding declaration".
* test-suite/tests/coding.test (scan-coding): Use 'file-encoding' to
scan for the encoding, since 'open-input-file' no longer does so.
* libguile/keywords.c (scm_keyword_argument_error): New variable.
(scm_c_bind_keyword_arguments): New API function.
* libguile/keywords.h (enum scm_keyword_arguments_flags): New enum.

documentation.
* test-suite/standalone/test-scm-c-bind-keyword-arguments.c: New file.
* test-suite/standalone/Makefile.am: Add
test-scm-c-bind-keyword-arguments test.
* libguile/array-map.c: new function rafill, like scm_array_fill_int,
but factors GVSET out of the loop. Use it in scm_array_fill_x instead of
scm_array_fill_int.
* test-suite/tests/arrays.test: add test for array-fill! with stride != 1.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* libguile/ports-internal.h (struct scm_port_internal): Add new members
'at_stream_start_for_bom_read' and 'at_stream_start_for_bom_write'.
(SCM_UNICODE_BOM): New macro.
(scm_i_port_iconv_descriptors): Add 'mode' parameter to prototype.
* libguile/ports.c (scm_new_port_table_entry): Initialize
'at_stream_start_for_bom_read' and 'at_stream_start_for_bom_write'.
(get_iconv_codepoint): Pass new 'mode' parameter to
'scm_i_port_iconv_descriptors'.
(get_codepoint): After reading a codepoint at stream start, record
that we're no longer at stream start, and consume a BOM where
appropriate.
(scm_seek): Set the stream start flags according to the new position.
(looking_at_bytes): New static function.
(scm_utf8_bom, scm_utf16be_bom, scm_utf16le_bom, scm_utf32be_bom,
scm_utf32le_bom): New static const arrays.
(decide_utf16_encoding, decide_utf32_encoding): New static functions.
(scm_i_port_iconv_descriptors): Add new 'mode' parameter. If the
specified encoding is UTF-16 or UTF-32, make that precise by deciding
what byte order to use, and construct iconv descriptors based on the
precise encoding.
(scm_i_set_port_encoding_x): Record that we are now at stream start.
Do not open the new iconv descriptors immediately; let them be
initialized lazily.
* libguile/print.c (display_string_using_iconv): Record that we're no
longer at stream start. Write a BOM if appropriate.
* doc/ref/api-io.texi (BOM Handling): New node.
* test-suite/tests/ports.test ("set-port-encoding!, wrong encoding"):
Adapt test to cope with the fact that 'set-port-encoding!' does not
immediately open the iconv descriptors.
(bv-read-test): New procedure.
("unicode byte-order marks (BOMs)"): New test prefix.
