* libguile/foreign.c (scm_sizeof): Make sure the overall size is a
multiple of the alignment of the structure.
* test-suite/tests/foreign.test: Test size of { double, int8 }.
Although popular compilers allow it as long as the expression is of type
void, it violates C99 and some compilers choke on it.
* libguile/numbers.c (scm_euclidean_divide, scm_floor_divide)
(scm_ceiling_divide, scm_truncate_divide, scm_centered_divide)
(scm_round_divide): Don't use the return statement with an expression
from functions with return type void.
* libguile/libguile-2.0-gdb.scm (make-scm-pretty-printer-worker):
(%scm-pretty-printer): Refactor to avoid printing all struct / array
fields by hinting these as arrays. The resulting print is not as
faithful to the original data, but that's probably OK.
* libguile/goops.c (is_accessor_method, scm_compute_applicable_methods):
Fix regression from 51f66c9120 (2009).
Accessor methods are added on each subclass on which the slot is
present; therefore if a subclass doesn't have a method, then the
methods doesn't apply. Truly fixes#17355, unlike
583a23bf10.
* module/oop/goops.scm (compute-cmethod, compute-getter-method)
(compute-setter-method): Revert earlier changes.
* test-suite/tests/goops.test ("accessor slots"): Update for new
expectations, in agreement with Guile 1.8.
Fixes <http://bugs.gnu.org/19621>.
Before that, in 'cbip_fill_input', BUFFERED would be set to 0 when
reading from 'scm_getc' et al, because 'shortbuf' was being used. Thus,
we could eventually execute this line:
/* Copy the data back to the internal buffer. */
memcpy ((char *) c_port->read_pos, SCM_BYTEVECTOR_CONTENTS (bv),
c_octets);
But 'read_pos' would quickly point to the fields beyond 'shortbuf',
thereby leading to a corruption of the 'scm_t_port' itself.
* libguile/r6rs-ports.c (cbip_setvbuf): When READ_SIZE is 0, keep using
BV as the 'read_buf'.
(cbip_fill_input): Adjust assertion to accept 'read_buf_size = 1'.
* test-suite/tests/r6rs-ports.test ("7.2.7 Input Ports")["custom binary
input port unbuffered & 'get-string-all'", "custom binary input port
unbuffered UTF-8 & 'get-string-all'"]: New tests.
This yields a 50% improvement on the "narrow string" benchmark of
'hash.bm', 41% on "wide string", and 76% on "long string".
* libguile/hash.c (scm_i_string_hash): Rewrite to avoid
'scm_i_string_ref' calls.
This function has been unused internally for some time and is undocumented.
* libguile/hash.c (scm_string_hash): Wrap if #if SCM_ENABLE_DEPRECATED
== 1.
* libguile/hash.h (scm_string_hash): Likewise, and replace SCM_API with
SCM_DEPRECATED.
This shows a 19% improvement on the "string without escapes"
micro-benchmark of 'write.bm', and 12% on "string with escapes".
* libguile/print.c (iprin1) <scm_tc7_string>: Replace 'scm_i_string_ref'
loop with a call to 'write_string'.
(display_character): Adjust description of return value in comment.
(write_string): New function.
Fixes <http://bugs.gnu.org/18988>.
Reported by Chris Vine <chris@cvine.freeserve.co.uk>.
* libguile/filesys.c (scm_select): Clarify handling of signal
interruptions.
* doc/ref/posix.texi (Ports and File Descriptors): Adjust accordingly.
Fixes <http://bugs.gnu.org/19027>.
* libguile/bytevectors.c (scm_bytevector_fill_x): Accept fill arguments
between -128 and 255.
* test-suite/tests/bytevectors.test ("2.2 General Operations"): Add
tests.
* libguile/bytevectors.c (ULONG_MAX): Remove (unportable) fallback
definition. It is no longer used.
(scm_make_bytevector): Use 'size_t' instead of 'unsigned' for
indices. Use 'scm_t_uint8' instead of 'signed char' for elements
and c_fill. Previously relied on GNU-C-specific behavior when
casting integers in the range 128-255 to signed char.
(GENERIC_INTEGER_ACCESSOR_PROLOGUE, INTEGER_LIST_TO_BYTEVECTOR)
(scm_bytevector_eq_p, scm_bytevector_copy_x, scm_bytevector_copy)
(scm_bytevector_to_u8_list, scm_u8_list_to_bytevector)
(scm_bytevector_fill_x): Use 'size_t' instead of 'unsigned' for
indices. Use 'scm_t_uint8' for elements.
Fixes <http://bugs.gnu.org/18065>.
Reported and fixed by Glenn Michaels <gmichaels@Safe-mail.net>.
* libguile/error.c (scm_strerror): Convert the argument to a C integer
outside of the critical section, to avoid deadlock on error.
* THANKS: Add Glenn Michaels to the fixes section.
* libguile/load.c (scm_c_string_has_an_ext): Rename to...
(string_has_an_ext): ... this. Add docstring. Change
'str' to be an SCM, and remove 'len' parameter. Change loop body to
use 'scm_string_suffix_p'.
(search_path): Update accordingly.
* libguile/load.c (stringbuf_free): Remove.
(stringbuf_grow): Use 'scm_gc_malloc_pointerless' instead of 'scm_realloc'.
(search_path): Use stack-allocated INITIAL_BUFFER instead of
'scm_malloc'. Remove use of 'stringbuf_free'.
Suggested by David Kastrup <dak@gnu.org> in <http://bugs.gnu.org/13644>.
* libguile/read.c (scm_read_string_like_syntax): Accept "\(" as
equivalent to "(".
* doc/ref/api-data.texi (String Syntax): Document it.
* test-suite/tests/reader.test ("reading"): Add test.
Fixes <http://bugs.gnu.org/18495>.
* libguile/smob.h (SCM_SMOB_OBJECT_LOC, SCM_SMOB_OBJECT_0_LOC)
(SCM_SMOB_OBJECT_1_LOC, SCM_SMOB_OBJECT_2_LOC)
(SCM_SMOB_OBJECT_3_LOC): These elementary API macros have been broken
by commit 56164dc47f in 2009.
