* libguile/fluids.c (scm_make_undefined_fluid, scm_fluid_unset_x)
(scm_fluid_bound_p): New functions.
(fluid_ref): New function; like scm_fluid_ref, but will not throw an
error for unbound fluids.
(scm_fluid_ref, swap_fluid): Use `fluid_ref'.
* libguile/fluids.h (scm_make_undefined_fluid, scm_fluid_unset_x)
(scm_fluid_bound_p): New prototypes.
* libguile/vm-i-system.c (fluid_ref): If fluid is unbound, jump to
`vm_error_unbound_fluid'.
* libguile/vm-engine.c (VM_NAME)[vm_error_unbound_fluid]: New error
message.
* test-suite/tests/fluids.test ("unbound fluids")["fluid-ref of unbound
fluid", "fluid-bound? of bound fluid", "fluid-bound? of unbound
fluid", "unbound fluids can be set", "bound fluids can be unset"]: New
tests.
* libguile/Makefile.am:
* libguile/discouraged.c: Remove discouraged.c.
* libguile/deprecated.c:
* libguile/deprecated.h:
* libguile/discouraged.h: All functions and declarations moved from
discouraged.[ch] to deprecated.[ch], adding deprecation warnings.
* libguile/init.c: Remove discouraged init.
* libguile/numbers.c (scm_num2float, scm_num2double): Deprecate.
* test-suite/standalone/test-num2integral.c: Port to modern API.
* libguile/foreign.c (scm_i_pointer_print): Print in hexadecimal.
* doc/ref/api-foreign.texi (Modules and Extensions): Update for
"extensiondir", and a discussion of Guile versions.
(Foreign Variables): Fix discussion of types.
(Void Pointers and Byte Access): Fix typo.
* libguile/load.h:
* libguile/load.c (scm_sys_global_site_dir): New API, is what %site-dir
used to be.
(scm_sys_site_dir): Changed to be a version-specific dir.
(scm_init_load_path): Search the version-specific sitedir before the
global one.
* libguile/Makefile.am (libpath.h): Update SCM_SITE_DIR and
SCM_GLOBAL_SITE_DIR, as appropriate.
* libguile/vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
Fix some bugs reported by Michael Lucy -- both variants would happily
write beyond the end, and vector-move-right! didn't increment the
counter before copying in the reverse direction.
* test-suite/tests/vectors.test ("vector-move-left!"):
("vector-move-right!"): Add tests.
There was a race condition when building Guile since DOT_X_FILES didn't
depend on version.h, which is dynamically generated. Sometimes the
DOT_X_FILES are compiled before the version.h is generated and leads to
build failure. This patch fixed this problem.

For > 32 bit integers still in the fixnum range, scm_random() would
return random numbers with a lower range than specified.
* libguile/random.c (scm_i_mask32): New static inline function.
(scm_c_random): Use `scm_i_mask32'.
(scm_c_random64): New function, 64-bit variant of scm_c_random.
(scm_random): Use `scm_c_random64' instead of forming the 64-bit random
number in a bogus way.
* libguile/random.h: Added `scm_c_random64'.
* doc/ref/api-foreign.texi (Foreign Types): Remove bits about typed
foreign pointers. Add `void'.
(Foreign Variables): Update the doc of `dynamic-pointer' and the
`numptob' example. Remove `foreign-set!' and `foreign-ref'. Add
`pointer-address', `make-pointer', `%null-pointer', and
`null-pointer?'
(Void Pointers and Byte Access): Make it clear that wrapped pointers
are untyped. Remove `void' from here. Replace `foreign->bytevector'
and `bytevector->foreign' by `pointer->bytevector' and
`bytevector->pointer'. Add `dereference-pointer' and the rest of the
`numptob' example.
(Dynamic FFI): Update examples. Remove `%null-pointer' from here.
* libguile/dynl.c (scm_dynamic_pointer): Update docstring.
* libguile/foreign.c (scm_dereference_pointer,
scm_pointer_to_bytevector): Likewise.
* module/system/foreign.scm (null-pointer?): Add docstring.
* libguile/foreign.c (scm_make_pointer): Always call out to
`scm_from_pointer'.
(scm_from_pointer): Return NULL_POINTER when PTR and FINALIZER are
NULL.
* libguile/vm-engine.c (VM_NAME)[vm_error_unbound]: Add comment.
* libguile/vm-i-system.c (variable_ref): Attempt provide the name of X
in FINISH_ARGS.
* am/guilec (install-data-hook): Remove.
(guile_install_go_files): New variable.
($(guile_install_go_files)): New dependency.
* libguile/load.c (compiled_is_fresh): Check for ordering of STAT_SOURCE
and STAT_COMPILED, not equality.
* module/ice-9/boot-9.scm (load): Ditto.
* module/system/base/compile.scm (call-with-output-file/atomic): Don't
set the timestamp of TEMPLATE.
* libguile/random.h (scm_t_rstate): Include the rng in the rstate, so we
can actually have multiple rngs. Instead of reserved0 / reserved1,
reserve a double explicitly for scm_c_normal01.
(scm_c_uniform32): Change to call the rstate's rng.
* libguile/random.c: Change to access an rstate's rng through its rng
pointer.
(scm_c_normal01): Instead of a flag and a next double, just check that
the double is equal to 0.0. Excluding one value shouldn't affect the
distribution, right?
* libguile/random.c (scm_t_i_rstate): Move here from random.h, along
with prototypes for functions
(scm_i_uniform32, scm_i_init_rstate, scm_i_copy_rstate): Change to
take a stock scm_t_rstate as an arg, and cast it. This way we don't
cast the pointers below.
(scm_i_rstate_from_datum, scm_i_rstate_from_datum): Same and rename
from scm_i_init_rstate_scm / scm_i_expose_rstate.
(scm_c_rstate_from_datum): Rename from scm_c_make_rstate_scm.
(scm_datum_to_random_state, scm_random_state_to_datum): Rename from
scm_external_to_random_state and scm_random_state_to_external.
(scm_init_random): Remove casts.
* libguile/random.h (scm_t_rng): Rename init_rstate_scm, expose_rstate
vmethods to from_datum, to_datum. Remove internal definitions. Rename
to scm_c_rstate_from_datum, and provide scm_random_state_to_datum and
scm_datum_to_random_state.
* libguile/random.h (scm_t_rng): random_bits returns a scm_t_uint32.
(scm_i_uniform32, scm_t_i_rstate): Internal RNG returns a
scm_t_uint32, as advertised, instead of unsigned long.
(scm_c_random): Return a scm_t_uint32 instead of an unsigned long.
* libguile/random.c (scm_i_uniform32, scm_i_init_rstate_scm):
(scm_i_expose_rstate, scm_c_random, scm_c_random_bignum, scm_random)
(scm_init_random): Adapt types to match implementation.
Now the random number generator state can be obtained in external
(i.e. `read'/`write'-able) form via the new procedure
`random-state->external'. An externalized state can be reinstantiated by
calling `external->random-state'.
* libguile/random.c (scm_i_init_rstate_scm, scm_i_expose_rstate): New
internal functions.
* libguile/random.c (scm_c_make_rstate_scm, scm_external_to_random_state,
scm_random_state_to_external): New public functions.
* libguile/random.h: Add prototypes for the above functions.
* libguile/random.h (scm_t_rng): Add new fields `init_rstate_scm' and
`expose_rstate'.
* libguile/random.c (scm_init_random): Initialize the new fields in
`scm_the_rng'.
* libguile/random.c (scm_c_random): On platforms where `unsigned long' has 64
bit, generate up to 64 bit of randomness. This is expected by
scm_c_random_bignum(), and hence was a serious distortion of the random value
distribution for values exceeding 2^32. This change also fixes a crash when
the `m' argument is a value above 2^32.
R6RS character hex escapes do not conflict with legacy Guile octal
character escapes, so they can be enabled by default.
* libguile/read.c (scm_read_character): modified
* test-suite/tests/reader.test: modify character escape tests
* doc/ref/api-data.texi: modified
* doc/ref/api-options.texi: modified
The open-file port should use the 8-bit ISO-8859-1 encoding when
a file is opened using mode "b". Also, it should honor a "coding:"
declaration at the top of a file when reading files where it is present.
* libguile/fports.c (scm_open_file): modified
* test-suite/tests/ports.test: more tests for open-file
* doc/ref/api-io.texi (File Ports): more documentation for open-file
Note especially that the variable 'i' has two different uses in this
function, and they get confused.
* libguile/read.c (scm_i_scan_for_encoding): cleanup
* libguile/ports.c (scm_getc): Provide `u32_conv_from_encoding' with the
RESULT_BUF stack-allocated buffer to avoid heap allocation.
(find_valid_encoding): Likewise.
(scm_ungetc): Ditto with `u32_conv_to_encoding'.
* libguile/vm-engine.c: Add func_name local, for error reporting.
(vm_error_apply_to_non_list): New error case.
(vm_error_wrong_type_arg): Remove this generic error case.
(vm_error_wrong_type_apply): Remove FUNC_NAME -- no sense in seeing
"vm-debug-engine" in the error report.
(vm_error_not_a_pair, vm_error_not_a_bytevector)
(vm_error_not_a_struct, vm_error_not_a_thunk): Use func_name instead
of FUNC_NAME, so we can indicate what caused the error.
* libguile/vm-i-scheme.c (VM_VALIDATE_CONS, car, cdr, set-car!)
(set-cdr!): Indicate provenance of errors.
(VM_VALIDATE_STRUCT, struct-vtable):
(VM_VALIDATE_BYTEVECTOR, BV_FIXABLE_INT_REF, BV_INT_REF)
(BV_FLOAT_REF, BV_FIXABLE_INT_SET, BV_INT_SET, BV_FLOAT_SET): Same.
* libguile/vm-i-system.c (apply, tail-apply): Use
vm_error_apply_to_non_list.
* libguile/backtrace.h:
* libguile/backtrace.c (scm_display_error): Change "stack" arg to
"frame". Still accept stacks for backward compatibility.
(display_header, display_error_body): Show the source of the error, if
possible.
* libguile/init.c (scm_i_init_guile): Move the call to
scm_init_threads_default_dynamic_state after the call to
scm_load_startup_files, so that the default dynamic state is in the
(guile-user) module, not (guile).
* libguile/strings.c (STRINGBUF_CONTENTS): New macro.
(STRINGBUF_CHARS, STRINGBUF_WIDE_CHARS): Use it.
(scm_i_string_data): New function.
* libguile/strings.h (scm_i_string_data): New declaration.
* libguile/backtrace.h (scm_the_last_stack_fluid_var)
* libguile/backtrace.c (scm_init_backtrace): No more
scm_the_last_stack_fluid_var. The replacement is to resolve
`the-last-stack' in (ice-9 stack-catch).
(scm_backtrace_with_highlights): Accordingly, instead of backtracing
the last stack, backtrace the current stack.
* libguile/throw.h:
* libguile/throw.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_internal_stack_catch): Deprecate this
function.
* module/ice-9/save-stack.scm (the-last-stack): Move here from boot-9.
* module/ice-9/debug.scm:
* module/ice-9/debugger.scm: Use (ice-9 save-stack) for the-last-stack.
* module/ice-9/deprecated.scm (the-last-stack): Add deprecated shim.
