Signed-off-by: Dmitry Bogatov <KAction@gnu.org>
* libguile/list.c (scm_reverse_x): Do not validate first argument to
reverse! in advance. Instead undo reversal in error case.

This is a follow-up to e26ab06.
* libguile/print.c (scm_simple_format): Pass 1 to
SCM_VALIDATE_OPORT_VALUE, for 'destination'.
* test-suite/tests/format.test ("simple-format"): Add test.
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS): Fix bad assumption that
width was a byte width. Thanks very much to Barry Fishman for the
report, and to Daniel Llorens for tracking it down.
* test-suite/standalone/Makefile.am (test_srfi_4_CFLAGS):
* test-suite/standalone/test-srfi-4.c: Add test.
* libguile/Makefile.am (install-data-local): Rename to...
(install-data-hook): ... this. This guarantees that the rule runs
after libguile-2.0.so has been installed.
* libguile/Makefile.am (gen-scmconfig.$(OBJEXT)): When cross-compiling,
pass -DCROSS_COMPILING=1.
(c-tokenize.$(OBJEXT)): Likewise.

CROSS_COMPILING is undefined.
* libguile/gen-scmconfig.c: Likewise.
* libguile/numbers.h (SCM_SRS): Rewrite preprocessor test to avoid
left-shifting negative integers, and to test more comprehensively for
the behavior we need. Rewrite fallback implementation to avoid
unspecified behavior.
* libguile/srfi-60.c (scm_srfi60_rotate_bit_field): Avoid division by
zero in the (start == end) case. Rewrite inum case to work with
unsigned integers in two's complement format.
* test-suite/tests/srfi-60.test ("rotate-bit-field"): Add more tests.
* libguile/numbers.c (scm_logbit_p): If the requested bit is the sign
bit (or above), check the sign portably. Otherwise, ensure that we're
testing the bit in a two's complement representation.
(left_shift_exact_integer): Avoid left-shifting negative integers.
* libguile/vm-i-scheme.c (ash): Avoid left-shifting negative integers.
* configure.ac: Add -fwrapv when using GCC (or compatible), if
supported.
* libguile/numbers.h (SCM_I_MAKINUM): Cast to scm_t_bits (unsigned)
before shifting, to avoid undefined behavior.
* libguile/guile-snarf.in (modern_snarf): Rewrite sed script to cope
with newlines in the snarfed code segments, or multiple code segments
on the same line.
* module/scripts/snarf-check-and-output-texi.scm (process-stream):
Strip all 'hash' tokens from the stream.
(do-command): Remove special cases that handled 'hash' tokens
in a few places.
* libguile/c-tokenize.lex: Add %top directive to include <config.h>
first. This fixes builds on systems that use Gnulib's <stdio.h> and
similar replacements. See <http://hydra.nixos.org/build/9259627> for
an example.
* libguile/libguile-2.0-gdb.scm: New file.
* libguile/Makefile.am (install-data-local): New target. Based on code
from GNU libstdc++.
(EXTRA_DIST): Add 'libguile-2.0-gdb.scm'.
* doc/ref/api-debug.texi (GDB Support): New section.
* libguile/iselect.h:
* libguile/threads.c:
* libguile/deprecated.h: Rely on Gnulib for sys/select.h.
* libguile/filesys.c: Rely on Gnulib for 'lstat' and 'mkstemp'.
* libguile/vectors.c (scm_is_vector): Deprecate use on weak vectors and
arrays.
(scm_is_simple_vector): Deprecate use on weak vectors.

use on arrays.

* libguile/vectors.c (scm_vector_length, scm_c_vector_ref):
(scm_c_vector_set_x): Deprecate the use of vector-length, vector-ref,
and vector-set! as primitive generics.

(scm_c_uniform_vector_length, scm_uniform_vector_length)

(scm_c_uniform_vector_ref, scm_uniform_vector_ref):
(scm_c_uniform_vector_set_x, scm_uniform_vector_set_x):
(scm_uniform_vector_to_list)
(scm_uniform_vector_elements, scm_uniform_vector_writable_elements):
Deprecate. This interface lacked both generality and specificity.
The general replacement is array-length, array-ref, and friends on the
scheme side, or the array handle interface on the C side. On the
specific side of things, there are the specific bytevector, srfi-4,
and bitvector interfaces.
* test-suite/tests/arrays.test:
* test-suite/tests/bitvectors.test:
* test-suite/tests/ports.test:
* test-suite/tests/srfi-4.test: Update to use array interfaces.

* doc/ref/srfi-modules.texi (SRFI-4): Update.
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS): In the raw element
accessors (e.g scm_u32vector_writable_elements), only permit
bytevectors, as the constructors will only make bytevectors. This
harmonizes with the Scheme interfaces as well, which expect packed
bytevectors.
(scm_make_srfi_4_vector): Knowing that the new value is a bytevector
with base 0 and inc 1, simplify initialization.
* libguile/hashtab.c (scm_make_doubly_weak_hash_table): Make 'size'
argument optional, like the weak hash table constructors.
* doc/ref/api-memory.texi (Weak hash tables): Document that 'size'
argument is optional for the weak hash table constructors.
* libguile/vectors.c (scm_vector_length, scm_c_vector_length):
(scm_c_vector_ref, scm_c_vector_set_x): Deprecate the use of these
procedures on weak vectors.
* test-suite/tests/guardians.test:
* test-suite/tests/weaks.test: Adapt test suites.
* libguile/weaks.c (scm_is_weak_vector, scm_c_weak_vector_length):
(scm_c_weak_vector_ref, scm_c_weak_vector_set_x): New interfaces for
dealing with weak vectors from C.
(scm_weak_vector_length, scm_weak_vector_ref, scm_weak_vector_set_x):
New Scheme interfaces to weak vectors; to be used instead of
vector-length, vector-ref, etc.
* module/ice-9/weak-vector.scm: Export the new interfaces.
* doc/ref/api-memory.texi (Weak vectors): Document them.
* libguile/r6rs-ports.c (CBIP_BUFFER_SIZE): Adjust comment. Set to 8KiB.
(SCM_SET_CBIP_BYTEVECTOR): New macro.

(make_cbip): Set PORT's 'setvbuf' internal field.
(cbip_fill_input): Check whether PORT is buffered. When unbuffered,
check whether BV can hold C_REQUESTED bytes, and allocate a new
bytevector if not; copy the data back from BV to c_port->read_pos.
Remove 'again' label, and don't loop there.
* test-suite/tests/r6rs-ports.test ("7.2.7 Input Ports")["custom binary
input port unbuffered & 'port-position'", "custom binary input port
unbuffered & 'read!' calls", "custom binary input port, unbuffered
then buffered", "custom binary input port, buffered then unbuffered"]:
New tests.
* doc/ref/api-io.texi (R6RS Binary Input): Document the buffering of
custom binary input ports, and link to 'setvbuf'.
* libguile/ports-internal.h (struct scm_port_internal): Add
setvbuf' field. Change 'pending_eof' to a 1-bit unsigned char.
* libguile/ports.c (scm_new_port_table_entry): Clear 'pti->setvbuf'.
* libguile/fports.c (scm_setvbuf): Accept any open port, and error out
when PORT's setvbuf' field is NULL. Remove explicit 'scm_gc_free' calls.
(scm_i_fdes_to_port): Set PORT's 'setvbuf' field.
* test-suite/tests/ports.test ("setvbuf")["closed port", "string port"]:
New tests.
* doc/ref/posix.texi (Ports and File Descriptors): Suggest that
'setvbuf' works for different port types.
Fixes <http://bugs.gnu.org/16463>.

* libguile/read.c (ENCODING_NAME_MAX_SIZE): New macro.
(SCM_ENCODING_SEARCH_SIZE): Change to 500 + ENCODING_NAME_MAX_SIZE.

ENCODING_NAME_MAX_SIZE bytes once "coding: *" has been read.

input port 'read!' returns too much"]: New test.
* libguile/print.c (print_r7rs_extended_symbol): Print any unicode
graphic character other than '|' or '\' unescaped. Escape any spacing
character other than ASCII space.
* libguile/print.c (scm_print_opts): Add 'r7rs-symbols' print option.
(symbol_has_extended_read_syntax): If the 'r7rs-symbols' option is
enabled, then disallow '|' and '\' from bare symbols.
(print_extended_symbol): Use 'scm_lfwrite' and 'scm_putc' instead of
'display_string' and 'display_character' when printing ASCII literals.
(print_r7rs_extended_symbol): New static function.
(scm_i_print_symbol_name): If the 'r7rs-symbols' option is enabled,
use 'print_r7rs_extended_symbol' instead of 'print_extended_symbol'.
* libguile/private-options.h (SCM_PRINT_R7RS_SYMBOLS_P): New macro.
(SCM_N_PRINT_OPTIONS): Increment.
* doc/ref/api-evaluation.texi (Scheme Write): Mention 'r7rs-symbols'
