("file-system-fold", "file-system-tree"): New test prefixes.
* doc/ref/misc-modules.texi (File Tree Walk): Document
`file-system-tree' and `file-system-fold'.
* module/ice-9/session.scm: #:keyword-ify the define-module form, and
export apropos-hook.
(apropos-hook): New hook.
(apropos, apropos-fold): Run the apropos-hook.

temporarily.
* module/ice-9/boot-9.scm (fluid->parameter): Turn `current-input-port'
et al into srfi-39 parameters, backed by the exported fluids, then
remove the fluids from the guile module.
(%cond-expand-features): Add srfi-39.
* module/srfi/srfi-39.scm: Re-export features from boot-9.
* test-suite/tests/parameters.test: Add tests.
* configure.ac: Add checks for GC_gcollect_and_unmap and
GC_get_unmapped_bytes.
* libguile/gc-malloc.c (scm_realloc): GC_gcollect() if we don't have
GC_gcollect_and_unmap.
* libguile/gc.c (GC_get_heap_usage_safe): Likewise, don't
GC_get_unmapped_bytes if the function doesn't exist.
Reported by Cédric Cellier <rixed@happyleptic.org>.
* module/language/tree-il/peval.scm (truncate-values): New procedure.
(make-operand): Call `truncate-values' SOURCE.
* test-suite/tests/tree-il.test ("partial evaluation"): New tests for
multiple value truncation.
* module/web/uri.scm (parse-authority): Allow empty authorities, so that
we accept URIs of the form, file:///etc/hosts.
* test-suite/tests/web-uri.test ("string->uri"): Add tests.
* 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.
* module/ice-9/boot-9.scm (<parameter>, make-parameter, parameter?)
(parameter-fluid, parameter-converter, parameterize): New top-level
bindings, implementing SRFI-39 parameters. Currently,
current-input-port and similar procedures are not yet parameters.
* test-suite/Makefile.am:
* test-suite/tests/parameters.test: Add tests, taken from srfi-39
tests.
* 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.
* module/system/repl/command.scm (language): Set the
*current-language*.
* module/system/repl/repl.scm (start-repl): Create a new dynamic scope
for *current-language*.
* 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.
* module/web/http.scm (default-val-validator): Valid with no value.
(key-value-list?): Keys are always symbols, do not accept strings.
(validate-param-list): Apply `valid?' to list elements.
(validate-credentials): Validate param for Basic scheme, which
is parsed as a string.
(declare-symbol-list-header!): `list-of?' args were in wrong order.
("Cache-Control"): Replace `default-val-validator' with more
specific procedure.
("Accept"): Validate on first param which has no value.
* am/guilec (.scm.go): Use `-L' to specify the search path.
* module/Makefile.am (ice-9/psyntax-pp.go): Likewise.
* meta/uninstalled-env.in (top_builddir): Leave $GUILE_LOAD_PATH,
$GUILE_SYSTEM_PATH, and $GUILE_SYSTEM_EXTENSIONS_PATH unchanged when
cross-compiling.
* 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.
* module/system/base/target.scm (validate-target): Accept any tuple with
at least 3 parts.
* test-suite/tests/asm-to-bytecode.test (test-triplet): New procedure.
("cross-compilation"): New test prefix.
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.
* test-suite/tests/eval.test ("stacks"): Enable another test, fix to use
with-throw-handler, and remove a duplicate test, now that there is no
difference between subrs and gsubrs.
* 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.
* doc/ref/intro.texi (Introduction):
* doc/ref/scheme-reading.texi (Further Reading):
* doc/ref/srfi-modules.texi (SRFI Support): Fix some urls. Thanks to
Henrik Sandklef for the report.
