* libguile/ports.h (struct scm_t_port): Make the lock into a pointer
field instead of an inline field. It should be possible to make
unlocked ports by having a NULL lock field.
(scm_c_lock_port, scm_c_try_lock_port): Return the mutex if the port
was actually locked.
(scm_c_unlock_port): Remove.
* libguile/ports.c (scm_c_make_port_with_encoding): For now, leave
`lock' set to 0.
Change scm_c_lock_port callers to pay attention to the new API.
* libguile/print.c (scm_write, scm_display): Fix call to
dynwind-lock-port for ports-with-print-states.
* libguile/ports.h:
* libguile/ports.c (scm_current_warning_port)
(scm_set_current_warning_port): New functions, wrapping the Scheme
parameter.
* module/ice-9/boot-9.scm (current-warning-port): New parameter,
defining a port for warnings.
* libguile/private-options.h (SCM_PRINT_ESCAPE_NEWLINES_P):
* libguile/print.c: Add new escape-newlines print option, defaulting to
on.
(write_character): For newlines, if SCM_PRINT_ESCAPE_NEWLINES_P, then
print them as \n.
(scm_init_print): Refactor print options initialization.
* libguile/numbers.c (custom_gmp_malloc, custom_gmp_realloc,
custom_gmp_free): New static functions used by GMP for allocation.
These are just wrappers for scm_malloc, scm_realloc, and free.
(scm_init_numbers): If scm_install_gmp_memory_functions is nonzero,
use mp_set_memory_functions to configure GMP to use
custom_gmp_{malloc,realloc,free} for memory allocation.
(scm_bigprint): Ask gmp for the function used to deallocate the string
returned by mpz_get_str.
* libguile/numbers.h: Declare scm_install_gmp_memory_functions.
* libguile/guile.c: When running the Guile binary, install the
gmp_memory_functions.
Based on a patch by Mark H Weaver <mhw@netris.org>.
* libguile/gc-malloc.c (scm_realloc): Call the new
scm_gc_register_allocation() here. If we have to collect, do a
GC_gcollect_and_unmap.
* libguile/gc.c (scm_gc_register_allocation): Add a routine to track
steady-state mallocation, and cause gc to run if there is a high
mallocation rate.
(adjust_gc_frequency): Reset the bytes-until-GC countdown timer.
* libguile/threads.c (scm_call_with_new_thread): Collect a little before
making a new thread. Our adjust_gc_frequency hack doesn't work well
if the main allocation load is thread creation, as in
https://savannah.gnu.org/bugs/?34140. This does not appreciably
affect the speed of the test in that bug, but does effectively limit
the image size.
* configure.ac: Check for GC_get_free_space_divisor.
* libguile/gc.c (GC_get_free_space_divisor): Define an implementation,
if needed.
(accumulate_gc_timer): Fix indentation.
(get_image_size): New terrible hack. Needs implementations on other
platforms.
(adjust_gc_frequency): Attempt to adjust the GC frequency based on
process image growth. Needs more comments.
(scm_init_gc): Add the adjust_gc_frequency to the after_gc_c_hook.
* libguile/foreign.c (scm_procedure_to_pointer): Keep a weak reference
to PROC.
* test-suite/tests/foreign.test ("procedure->pointer")["procedure is
retained"]: New test.
* libguile/struct.h:
* libguile/struct.c (scm_make_vtable_vtable): Deprecate, as you can
handle most of the use cases with make-vtable, and we don't want to
promote the creation of new roots to the type hierarchy.
(scm_i_make_vtable_vtable): The internal replacement.
* libguile/options.c (change_option_setting, scm_init_options): Rely on
the options being allocated in GC-able memory, as in static memory.
Therefore there is no need for the gc-protect dance.
* libguile/fluids.c (grow_dynamic_state, new_fluid): Arrange for the
default value in the dynamic-state vector to be SCM_UNDEFINED instead
of SCM_BOOL_F. If the value in the dynamic-state is #f, default to a
value attached to the fluid instead. This allows useful default
values.
(scm_make_fluid_with_default): New function, allows the user to
specify a default value for the fluid. Defaults to #f. Bound to
`make-fluid' on the Scheme side.
(scm_make_unbound_fluid): Use SCM_UNDEFINED as the default in all
threads.
(scm_fluid_unset_x): Also unset the default value. Not sure if this
is the right thing.
(fluid_ref): Update to the new default-value strategy.
* libguile/threads.c (scm_i_reset_fluid): Reset to SCM_UNDEFINED.
* libguile/threads.h: Remove extra arg to scm_i_reset_fluid.
* libguile/vm-i-system.c (fluid-ref): Update to new default-value
strategy.
* module/ice-9/vlist.scm (block-growth-factor): Default to 2 in all
threads. Fixes http://debbugs.gnu.org/10093.
* module/system/base/target.scm (%target-endianness, %target-word-size):
New fluids.
(%native-word-size): New variable.
(with-target): Set these fluids.
(cpu-endianness, cpu-word-size, triplet-cpu, triplet-vendor,
triplet-os): New procedures.
(target-cpu, target-vendor, target-os): Use them.
(target-endianness, target-word-size): Refer to the corresponding
fluid.
* libguile/objcodes.c (target_endianness_var, target_word_size_var): New
global variables.
(NATIVE_ENDIANNESS): New macro.
(target_endianness, target_word_size, to_native_order): New functions.
(make_objcode_from_file): Use `scm_bytecode_to_native_objcode' instead
of `scm_bytecode_to_objcode'.
(bytecode_to_objcode): New function, based on `scm_bytecode_to_objcode',
with the addition of an `endianness' and `word_size' parameters.
(scm_bytecode_to_objcode): Use it.
(scm_bytecode_to_native_objcode): New function.
(scm_write_objcode): Use `target_word_size' and `target_endianness'.
Convert OBJCODE's len and meta-len to native byte order.
(scm_init_objcodes): Initialize `target_endianness_var' and
`target_word_size_var'.
* libguile/objcodes.h (scm_bytecode_to_native_objcode): New declaration.
* libguile/vm.c (really_make_boot_program): Use
`scm_bytecode_to_native_objcode' instead of `scm_bytecode_to_objcode'.
* test-suite/tests/asm-to-bytecode.test (%objcode-cookie-size): New
variable.
(test-target): New procedure.
("cross-compilation"): Add `test-target' calls and the "unknown
target" test.
Reported by Dmitry Chestnykh <dmitry@codingrobots.com>.
Fixes <http://debbugs.gnu.org/10070>.
* libguile/bytevectors.c (scm_bytevector_copy_x): Use `memmove', not
`memcpy'.
* test-suite/tests/bytevectors.test ("2.2 General
Operations")["bytevector-copy! overlapping"]: New test.
* doc/ref/api-data.texi (Bytevector Manipulation): Mention possible
overlapping.
* libguile/foreign.c (scm_procedure_to_pointer): Keep a weak reference
to CIF so that it is not reclaimed before POINTER. Before that it
could be reclaimed and typically reused to store the CIF of another
procedure with the same arity, leading to obscure wrong-type-arg
errors.
* libguile/procprop.c (scm_set_procedure_minimum_arity_x): New
function, allows a user to override a function's arity.
(scm_i_procedure_arity): Look up in the overrides table first.
* libguile/procprop.h: Add scm_set_procedure_minimum_arity_x.
* module/ice-9/eval.scm (primitive-eval): Override arity of "general
closures".
* test-suite/tests/procprop.test ("procedure-arity"): Add tests.
Based on a patch from Stefan Israelsson Tampe. Test based on work by
Patrick Bernaud.
* libguile/bitvectors.c (scm_bit_set_star_x): Fix a long-standing (since
2005) bug in which instead of using the kv bitvector, we actually use
the `v' bitvector. Also, change to allow `kv' being shorter than
`v'.
* test-suite/tests/bitvectors.test ("bit-set*!"): Add tests.
* libguile/ports.h (scm_c_lock_port, scm_c_try_lock_port)
(scm_c_unlock_port): Disable port locking until I have time to sort
out the bugs that are coming up.
* libguile/ports.c (scm_putc, scm_puts):
* libguile/ports.h (scm_putc_unlocked, scm_puts_unlocked): Separate into
_unlocked and locked variants. Change all callers to use the
_unlocked versions.
* libguile/ports.c (scm_c_read_unlocked, scm_c_read, scm_getc_unlocked)
(scm_getc): Split getc and read operations into locked and unlocked
variants. Change most uses to use the _unlocked version.
* libguile/ports.h (scm_get_byte_or_eof_unlocked):
(scm_peek_byte_or_eof_unlocked): Rename, adding _unlocked.
* libguile/ports.c (scm_get_byte_or_eof, scm_peek_byte_or_eof): Add
locking implementations. Adapt callers to use _unlocked variants;
they will do locking.
* libguile/read.c (read_token, scm_read_semicolon_comment)
(scm_read_shebang): Use unlocked variants. We will add locking
later.
