* 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.
* libguile/_scm.h (SCM_OBJCODE_ENDIANNESS_OFFSET):
(SCM_OBJCODE_WORD_SIZE_OFFSET): New defines.
* libguile/objcodes.c (scm_write_objcode): Use target-endianness and
target-word-size when writing the objcode cookie.
* libguile/hashtab.c (scm_internal_hash_fold): Don't try to unlink
deleted weak pairs. Our previous code was buggy (`prev' should have
only been updated in the case of a successful traversal), but more
than that, we're not in the alloc lock.
Thanks very much to Michael Wells for the report, and the debugging!
* libguile/scmsigs.c (read_signal_pipe_data, signal_delivery_thread):
Leave guile when reading from the signal pipe. Hopefully that lets GC
know not to wake up this thread.
* libguile/inline.h:
* libguile/gc.c: Remove declaration and definition of unused
"scm_newcell_count" and "scm_newcell2_count". Since SCM_INTERNAL is
"extern", these symbols were not externally visible anyway, at least
under Linux or Windows.
* libguile/inline.h:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_immutable_cell, scm_immutable_double_cell):
Deprecate these, as the GC_STUBBORN API doesn't do anything any more.
* libguile/strings.c (scm_i_c_make_symbol): Change the one use of
scm_immutable_double_cell to scm_double_cell.
* libguile/goops.c (scm_i_define_class_for_vtable): Lock around
additions to the vtable_class_map. Use is unlocked though; solving
GOOPS parallel-initialization would be a good thing.
* libguile/srcprop.h: Remove internal scm_source_whash declaration.
* libguile/srcprop.c (scm_i_set_source_properties_x)
(scm_i_has_source_properties): New helpers.
(scm_source_whash): Make static.
* libguile/read.c (scm_read_sexp): Remove register declarations here;
let's trust the compiler. Remove code to incrementally build up a
copy; instead let's let scm_i_set_source_properties_x handle copying
the expression if needed.
(scm_read_quote, scm_read_syntax): Use scm_i_set_source_properties_x.
(recsexpr): Remove this helper from 1996.
(scm_read_sharp_extension): Instead of trying to recursively label
sharp-read subforms with source properties, just label the outside
form and rely on the macro-expander to propagate it down.
* libguile/symbols.c (symbols_lock): Rename from intern_lock.
(lookup_interned_symbol, lookup_interned_latin1_symbol): Instead of
faith-based programming, just use the mutex. Though I haven't seen
this break, Ken is right!
* libguile/threads.c (lock_mutex_return_void, unlock_mutex_return_void):
New static functions that simply call scm_lock_mutex and
scm_unlock_mutex, respectively, but return void instead of SCM.
(scm_dynwind_lock_mutex): Pass unlock_mutex_return_void to
scm_dynwind_unwind_handler_with_scm, and lock_mutex_return_void to
scm_dynwind_rewind_handler_with_scm. Previously, we passed
scm_unlock_mutex and scm_lock_mutex (which return SCM), but the
scm_dynwind_* functions expect pointers to functions which return
void. When SCM is of type union, this changes the calling conventions
of the functions on some platforms (e.g. GCC 4.5.2 and 4.5.3 on x86).
* libguile/inline.h (scm_cell, scm_immutable_cell):
(scm_double_cell, scm_immutable_double_cell):
(scm_words): Be more consistent in use of PTR2SCM and SCM2PTR.
* libguile/hashtab.c (set_weak_cdr):
* libguile/vectors.c (scm_c_vector_set_x):
* libguile/weaks.c (scm_weak_car_pair, scm_weak_cdr_pair):
(scm_doubly_weak_pair): Use SCM2PTR for the target of
SCM_I_REGISTER_DISAPPEARING_LINK calls.
* libguile/dynwind.c:
* libguile/dynwind.h:
* libguile/deprecated.h (scm_t_inner):
* libguile/deprecated.c (scm_internal_dynamic_wind): Deprecate, as the
scm_dynwind API is better, and this API encourages users to stuff SCM
values into pointers.
* libguile/async.c (increase_block, decrease_block): Write more
clearly.
(scm_dynwind_block_asyncs, scm_dynwind_unblock_asyncs): Move
definitions up.
(scm_call_with_blocked_asyncs, scm_c_call_with_blocked_asyncs)
(scm_call_with_unblocked_asyncs, scm_c_call_with_unblocked_asyncs):
Implement in terms of scm_dynwind_{un,}block_asyncs, so that we don't
stuff SCM values into pointers.
* libguile/numbers.c (scm_logand): Fix a type error (comparing a SCM
against an int, when we really wanted to compare the unpacked
fixnum).
* libguile/ports.c (scm_i_set_conversion_strategy_x): Check
scm_conversion_strategy_init, not scm_conversion_strategy.
* libguile/read.c (recsexpr): Fix loops to avoid strange test of SCM
values.
* libguile/tags.h (SCM_MAKE_ITAG8_BITS): New helper, produces a
scm_t_bits instead of a SCM, because SCM_UNPACK is not a constant
expression with SCM_DEBUG_TYPING_STRICTNESS==2.
(SCM_MAKIFLAG_BITS): Remove SCM_MAKIFLAG, and replace with this, which
returns bits.
(SCM_BOOL_F_BITS, SCM_ELISP_NIL_BITS, SCM_EOL_BITS, SCM_BOOL_T_BITS):
(SCM_UNSPECIFIED_BITS, SCM_UNDEFINED_BITS, SCM_EOF_VAL_BITS):
(SCM_UNBOUND_BITS): New definitions. Defined SCM_BOOL_F, etc in terms
of them.
(SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_0):
(SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_1):
(SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_2):
(SCM_XXX_ANOTHER_LISP_FALSE_DONT_USE): Be bits instead of SCM values.
(SCM_BITS_DIFFER_IN_EXACTLY_ONE_BIT_POSITION):
(SCM_BITS_DIFFER_IN_EXACTLY_TWO_BIT_POSITIONS): Rename from
SCM_VALUES_DIFFER_..., and take unpacked bits as the args.
* libguile/boolean.c: Update verify block to use
SCM_BITS_DIFFER_IN_EXACTLY_TWO_BIT_POSITIONS et al.
* libguile/debug.c (scm_debug_opts):
* libguile/print.c (scm_print_opts):
* libguile/read.c (scm_read_opts): Use iflags bits for initializers.
* libguile/hash.c (scm_hasher): Use _BITS for iflags as case labels.
* libguile/pairs.c: Nil/null compile-time check uses
SCM_ELISP_NIL_BITS.
* libguile/tags.h (SCM): For SCM_DEBUG_TYPING_STRICTNESS==2, give the
union a tag, and use C99 compound literals to construct the value.
This allows SCM_PACK to be a constant expression.
* libguile/snarf.h: Allow SCM_SUPPORT_STATIC_ALLOCATION for
SCM_DEBUG_TYPING_STRICTNESS==2.
(SCM_IMMUTABLE_STRING): Properly parenthesize the string length.
(SCM_STATIC_PROGRAM): Fix for SCM_DEBUG_TYPING_STRICTNESS==2.
* libguile/foreign.c (pack): Add `return_value_p' parameter. Update
callers.
When RETURN_VALUE_P is true, assume LOC points to an `ffi_arg', and
cast its results to the relevant type. This fixes packing of integer
return values smaller than `int' on SPARC64 and PowerPC64. Reported
by Nelson H. F. Beebe <beebe@math.utah.edu>.
Thanks to Mark H. Weaver for pointing this out.
* libguile/ports.c (CONSUME_PEEKED_BYTE): New macro.
(get_utf8_codepoint): New variable `pt'. Use
`scm_peek_byte_or_eof'/`CONSUME_PEEKED_BYTE' pairs instead of
`scm_get_byte_or_eof'.
* test-suite/tests/ports.test ("string ports")[#xc2 #x41 #x42, #xe0 #xa0
#x41 #x42, #xf0 #x88 #x88 #x88]: Fix to conform to Unicode 6.0.0.
[#xe0 #x88 #x88]: Remove test.
[#xf0 #x80 #x80 #x41]: New test.
* libguile/inline.h (scm_get_byte_or_eof): Add `SCM_UNLIKELY' for EOF.
(scm_peek_byte_or_eof): New function.
* libguile/r6rs-ports.c (scm_lookahead_u8): Use `scm_peek_byte_or_eof'.
* libguile/ports.c (update_port_lf): Handle EOF.
(get_utf8_codepoint, get_iconv_codepoint): New functions.
(get_codepoint): Use them.
(scm_i_set_port_encoding_x): Don't open conversion descriptors when
ENCODING is "UTF-8".
* libguile/print.c (display_string_as_utf8, display_string_using_iconv):
New functions.
(display_string): Use them.
* test-suite/tests/ports.test ("string ports")[#xc2 #x41 #x42]: Add a
note that this is not the wrong behavior per Unicode 6.0.0.
