* doc/ref/api-data.texi (Exact and Inexact Numbers): doc for scm_is_exact
and scm_is_inexact
* libguile/numbers.c (scm_is_exact, scm_is_inexact): new functions
* libguile/numbers.h: declarations for scm_is_exact and scm_is_inexact
* test/suite/standalone/test-conversion.c (test_is_exact, test_is_inexact):
new tests
* libguile/read.c (scm_read_r6rs_block_comment):
* test-suite/tests/reader.test ("reading"): Fix reading of #||||#,
originally reported in bug debbugs.gnu.org/9672, by Bruno Haible.
Thanks, Bruno!
* libguile/strings.c (scm_to_latin1_stringn): Fix for substrings.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-scm-to-latin1-string.c: Add test case.
Thanks to David Hansen for the bug report and test case, and Stefan
Israelsson Tampe for the fix.
* libguile/bytevectors.h:
* libguile/bytevectors.c (scm_c_take_gc_bytevector): Rename this
internal function, from scm_c_take_bytevector. This indicates that
unlike the other scm_take_* functions, this one takes GC-managed
memory.
* libguile/objcodes.c (scm_objcode_to_bytecode):
* libguile/vm.c (really_make_boot_program): Use
scm_gc_malloc_pointerless, not scm_malloc. Thanks to Stefan
Israelsson Tampe!
* libguile/r6rs-ports.c:
* libguile/strings.c: Adapt to renames.
* libguile/posix.c (scm_tmpfile): Fix to actually close the new
tmpfile, causing its deletion, while keeping an fd to the file open.
Fixes a leak both in memory and disk space on POSIX systems; MINGW
systems will leak however. A FIXME for later.
* libguile/i18n.c (get_current_locale): Hold the locale name in a
GC-managed string, not a mallocated string. Thanks to Stefan
Israelsson Tampe for the report.
* libguile/srfi-1.h:
* libguile/srfi-1.c (scm_srfi1_drop_right, scm_srfi1_take_right): Remove
these internal functions, replacing with Scheme implementations.
* module/srfi/srfi-1.scm (take-right, drop-right): Add these impls from
the reference code. They do the right thing for improper lists,
according to the spec, but they diverge for circular lists. Oh well.
* test-suite/tests/srfi-1.test ("drop-right", "take-right"): Add more
tests.
* libguile/load.c (search_path): Extract from scm_search_path, to
give the caller the stat buffer of the found path.
(scm_search_path, scm_sys_search_load_path): Adapt accordingly.
(compiled_is_fresh): Take the stat buffers directly.
(scm_primitive_load_path, scm_init_eval_in_scheme): Adapt to
search_path / compiled_is_fresh changes to avoid duplicate states in
search-path.
* libguile/load.c (scm_primitive_load_path): Don't canonicalize the
filename unless we need to look in the fallback path. Fixes a stat
explosion; see http://savannah.gnu.org/bugs/?33815.
* 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.
* 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.
* 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.
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/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 "/".

* libguile/threads.c (fat_mutex_lock): In the `m->level == 0' case,
release M's lock before taking T's `admin_mutex'.
* libguile/strings.c (scm_i_allocate_string_pointers): Encode strings
using the current locale. Previously, Latin-1 was used. Indirectly,
this affects the encoding of strings in `system*', `execl', `execlp',
`execle', `environ', and `dynamic-args-call'.
(scm_makfromstrs): In header comment, clarify that the C strings are
interpreted according to the current locale encoding.
* NEWS: Add NEWS entry.
Added pipe2 and open modules, to get O_CLOEXEC.
* libguile/Makefile.am (guile_filter_doc_snarfage$(EXEEXT)): Add gnulib
here, in the native build case, for rpl_fflush if needed.
foo
* libguile/threads.h:
* libguile/threads.c (scm_i_reset_fluid): New internal function, resets
the binding of a fluid for all threads. Needed for fluid GC.
* libguile/fluids.c (new_fluid): Call scm_i_reset_fluid here.
* test-suite/tests/weaks.test: Add tests.
* libguile/hashtab.c (scm_hash_fn_set_x): Fix updates to weak-value hash
tables to not deadlock inside the alloc lock.
