* 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).
* module/ice-9/boot-9.scm (define-module): Fix to load the #:use-module
clauses in the order in which they appear in the define-module form.
Thanks to Jan Nieuwenhuizen for the report.
* test-suite/standalone/test-import-order: Add new test that
define-module and use-modules resolve the interface in the right
order.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-import-order-a.scm:
* test-suite/standalone/test-import-order-b.scm:
* test-suite/standalone/test-import-order-c.scm:
* test-suite/standalone/test-import-order-d.scm: Aux files.
* doc/ref/api-evaluation.texi (Scheme Read): Note that read-set! is
syntax.
(Scheme Write): Likewise for print-set!.
* doc/ref/api-io.texi (Writing): Remove reference to
print-options-interface.
* doc/ref/repl-modules.texi (Readline Options): Update, and add entries
for readline-options, readline-set! et al.
* module/rnrs/io/ports.scm (open-file-output-port): Handle `no-fail'
file option.
(with-i/o-filename-conditions): Use `with-throw-handler' instead of `catch'.
(with-i/o-port-error,
with-textual-output-conditions. with-textual-input-conditions): New
exception-conversion helpers.
(put-char, put-datum, put-string, display): Use
`with-textual-output-conditions' instead of `with-i/o-encoding-error'
to get proper conditions in case of write errors.
(get-char, get-datum, get-line, get-string-all, lookahead-char):
Likewise, for the input case.
* test-suite/tests/r6rs-ports.test (pass-if-condition, test-file,
make-failing-port): New helpers.
("8.2.10 Output ports"): Add some tests for `open-file-output-port'.
("8.2.9 Textual Input"): Add tests read error conditions.
("8.2.12 Textual Output"): Add tests for write error conditions.
("8.3 Simple I/O"): Add tests for conditions, `call-with-input-file'
and `call-with-output-file'.
* 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.
* module/ice-9/vlist.scm (vlist-fold-right): Avoid `vlist-reverse' and
instead `vlist-ref' individual elements. The result is about twice
faster. Thanks Andy for suggesting it indirectly. :-)
* 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>.
* module/language/glil/compile-assembly.scm: Clean up code for
subprograms (not needed, we just cache the glil) and object alists
(replaced by constants tables).
* module/language/glil/compile-assembly.scm (compile-assembly): Rework
to handle toplevel-specific code generation here, instead of in
glil->assembly. Specifically, here we build a global constant table,
and arrange for it to be the objtable of the toplevel thunk.
(compile-program): New helper, compiles a <glil-program> and returns
just the (load-program ...) form.
(compile-objtable): New helper, generates assembly to build an object
table, using some other constants table, and possibly recursing to
`compile-program' for cached GLIL programs.
(glil->assembly): Simplify, removing the toplevel? argument, and
replacing the object alist with an objtable computed in a previous
pass. Adapt to the new form of the objtable, and to use
compile-program and compile-objtable.
* module/language/glil/compile-assembly.scm (dump-constants): New
helper. Generates bytecode that will result in a vector for the
global object table being pushed on the stack. The items in the
global object table will share state as much as possible.
* module/language/glil/compile-assembly.scm (immediate?): New helper.
(build-constant-store): New helper. Walks the GLIL tree and builds up
a constant table, as a vhash.
(build-object-table): Another helper, builds a constant table for a
given GLIL program.
* module/rnrs/io/ports.scm (display): Implement as an
exception-converting wrapper around Guile's core display.
* module/rnrs/io/simple.scm: Don't export Guile's corresponding core
procedures, but use `(rnrs io ports)' instead. This way, we get the
conditions required by R6RS raised.
* doc/ref/r6rs.texi (rnrs io simple): Mention that these procedures are
supposed to raise R6RS conditions.
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'.
* module/srfi/srfi-1.scm (map-in-order): As we are not extending the
core `map' binding, actually make a new `map-in-order' alias here.
Fixes fresh builds.
* 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.
* libguile/__scm.h (SCM_ASYNC_TICK_WITH_CODE): Redefine to take a
scm_i_thread* as well. OK to do because it's within a
BUILDING_LIBGUILE block.
* libguile/vm-engine.c (vm_engine): Cache the scm_i_thread* instead of
the dynstate, so we can use the thread for ticks.
* libguile/vm-engine.h (VM_HANDLE_INTERRUPTS): Tick with the
scm_i_thread* local var, to avoid excessive tls calls.
* libguile/vm-i-system.c: Fix dynstate users to use
current_thread->dynamic_state.
