* libguile/Makefile.am (libpath.h): Define SCM_SITE_CCACHE_DIR. Defined
as site-ccache/ instead of site/ccache/ to indicate that we don't expect
further subdirectories, and also to avoid confusion about whether
extensions/ is a site-specific or not.
* libguile/load.c (scm_init_load_path): Add SCM_SITE_CCACHE_DIR to the
default load-compiled path.
* module/web/request.scm (build-request): Make sure that HTTP/1.1
requests have the Host header set, per RFC 2616 section 9.
* test-suite/tests/web-request.test ("example-1"): Add test.
* libguile/goops.c (fix_cpl): Fix bug in placement of debug assertion.
(create_standard_classes): Put <extended-generic> before
<generic-with-setter> in <extended-generic-with-setter>'s direct
supers, so that the slot allocation is a superset of
<generic-with-setter>, which results in the `setter' being allocated
in the same place.
Likewise fix <extended-accessor> to place <extended-generic> before
<generic-with-setter>, not just <generic>.
* libguile/modules.c (resolve_duplicate_binding): Fix unbound -> #f
conversion for the imported bindings. Pass the existing entry in the
import obarray as the resolved var (7th arg), and properly pass #f as
the value (8th arg) if there is no such binding. Fixes
merge-generics; before, the <boolean> type test (indicating no
previous value) was not being triggered. This bug has been present
since 2007 at least, though it was not in 1.8.
* test-suite/tests/modules.test ("duplicate bindings"): Add a test that
the var and val are both #f. These types are used by GOOPS.
* module/system/repl/command.scm (time): Use the high-precision timers
instead of stime(2). Changes the output format of `,time' too;
perhaps there is a better way.
* doc/ref/goops.texi (Merging Generics): Change (my-module) example to
use (oop goops) and use the right syntax for #:duplicates. Reported
by David Pirotte <david@altosw.be>.
* libguile/vm-engine.c (VM_NAME)[HAVE_LABELS_AS_VALUES]: Rename
`jump_table' to `jump_table_pointer'. Add `jump_table' as a local
variable, initialize it.
* libguile/vm-engine.h (JT_REG): New macro.
* GUILE-VERSION (GUILE_MICRO_VERSION): Increment.
(LIBGUILE_INTERFACE_CURRENT): Increment to account for new C function
`scm_peek_byte_or_eof'.
(LIBGUILE_INTERFACE_AGE): Increment.
This reverts commit ccb80964cd, which
introduced a race condition, with a small window during which a mutex
could be held by a thread without being part of its `mutexes' list,
thereby violating the invariant tested at line 667.
* libguile/bytevectors.c (COMPLEX_ACCESSOR_PROLOGUE, COMPLEX_NATIVE_REF,
COMPLEX_NATIVE_SET): New macros.
(bytevector_ref_c32, bytevector_ref_c64): Defined in terms of
`COMPLEX_NATIVE_REF'.
(bytevector_set_c32, bytevector_set_c64): Defined in terms of
`COMPLEX_NATIVE_SET'.
(bytevector_ref_fns): Make `static'.
* test-suite/tests/srfi-4.test ("c32 vectors")["generalized-vector-ref",
"generalized-vector-set!", "generalized-vector-ref, out-of-range",
"generalized-vector-set!, out-of-range"]: New tests.
("c64 vectors")["generalized-vector-ref", "generalized-vector-set!",
"generalized-vector-ref, out-of-range",
"generalized-vector-set!, out-of-range"]: New tests.
* libguile/bytevectors.c (bytevector_ref_c32, bytevector_ref_c64,
bytevector_set_c32, bytevector_set_c64): Use `memcpy' to avoid
unaligned accesses. This fixes SIGBUS on SPARC and possibly other
alignment-sensitive platforms.
* libguile/read.c (scm_read_sexp): Don't confuse `#{.}#' with `.' for
the purpose of reading dotted pairs. Thanks to CRLF0710 for the
report.
* test-suite/tests/reader.test ("#{}#"): Add test.
* libguile/goops.c (DEFVAR): Remove this helper macro, replacing its
uses with scm_module_define, but without scm_module_export.
(create_basic_classes, scm_init_goops_builtins): Update callers.
(make_class_from_template, make_class_from_symbol): Change to not
define variables for classes. This affects ports, struct classes, and
smob classes.
* module/oop/goops.scm: Explicitly list our exports, so there is no more
trickery happening in C.
(find-subclass): Private helper to grub the class hierarchy, so we can
define bindings for smobs, ports, etc. Use to define the classes that
goops.c used to define -- probably a subset, but it's better to have
them listed.
* libguile/threads.c (on_thread_exit): Clear `t->guile_mode' upon
entry. This fixes a bug whereby `t->base' would be incorrect for
canceled threads, leading to a misdiagnosed VM stack overflow.
See <http://lists.gnu.org/archive/html/bug-guile/2011-06/msg00068.html>
for details.
(scm_leave_guile_cleanup): Remove because it's unused.
* libguile/load.c (canonical_to_suffix, scm_primitive_load_path):
* module/ice-9/boot-9.scm (load-in-vicinity):
* module/system/base/compile.scm (compiled-file-name): If the canonical
path of a file is a DOS-style path with a drive letter, turn it into a
path suffix it by removing the colon and prefixing a "/".
Inspired by a patch from Jan Nieuwenhuizen.
* doc/ref/guile.texi (Programming in Scheme):
* doc/ref/scheme-scripts.texi (Guile Scripting): Moved "Invoking Guile"
to its own file.
* doc/ref/guile-invoke.texi (Invoking Guile): Initial revision. This
file contains the former section "Invoking Guile" that was included in
the chapter "Programming in Scheme" as a subsection named
"Command-line Options." It also includes a new subsection "Environment
Variables," which describes those variables that can be set in the
operating system before Guile is started and which affect Guile's
run-time behavior.

* libguile/threads.c (fat_mutex_lock): In the `m->level == 0' case,
release M's lock before taking T's `admin_mutex'.
* configure.ac: Add a check for GC_get_suspend_signal().
* libguile/scmsigs.c (GC_get_suspend_signal): Define a fallback
implementation if one isn't available.
(signal_delivery_thread): Unmask the suspend signal so that GC can
stop the world. Fixes test-pthread-create on libgc 7.1 and earlier.
Thanks to Frank Terbeck <ft@bewatermyfriend.org> for the report.
* module/ice-9/psyntax.scm (syntax-case): enabled the use of a
general last cdr instead of just '() in matching with both
a ellipsis (p ...) and a last rest pattern (. q)
* module/ice-9/psyntax-pp.scm: Regenerated.
This fixes warnings saying "this decimal constant is unsigned only in
ISO C90".
* test-suite/standalone/test-ffi-lib.c (test_ffi_u32_, test_ffi_u32_u8,
test_ffi_u32_s64, test_ffi_s64_s64, test_ffi_u64_u8,
test_ffi_u64_s64): Mark constants as unsigned.
* configure.ac: Remove code that determines the values of the `iconveh_'
constants. Use `GUILE_UNISTRING_ICONVEH_VALUES'. instead.
* acinclude.m4 (GUILE_UNISTRING_CONSTANT,
GUILE_UNISTRING_ICONVEH_VALUES): New macros.
* module/system/base/language.scm (current-language): Default to 'scheme
here, rather than relying on *current-language* always being bound.
