* libguile/frames.c (frame_procedure_name_var): New static definition.
(init_frame_procedure_name_var): New helper.
(scm_frame_procedure_name): New function that returns the name of the
frame's procedure, as frame-procedure is to be deprecated.
* libguile/frames.h (scm_frame_procedure_name): Export.
* module/ice-9/boot-9.scm (exception-printers): Use frame-procedure-name
instead of procedure-name on frame-procedure.
* module/system/vm/frame.scm (frame-procedure-name): New private
function, implementing scm_frame_procedure_name.
(frame-call-representation): Use frame-procedure-name to get the
procedure name to print.
* module/ice-9/eval.scm (primitive-eval): Specialize lexical-ref for
depths 0, 1, and 2. Speeds up this test by around 13%:
(primitive-eval '(let lp ((n 0)) (when (< n #e1e7) (lp (1+ n)))))
* module/ice-9/eval.scm (primitive-eval): Factor out primitive=?
helper. Simplify compile-top-call. Add compile-top-branch for
primcall branches, so the compiler can see the specialized branch
operator.
* module/ice-9/eval.scm (primitive-eval): Lazily compile lambda bodies.
Special-case calls to top-level or module variables, and recognize
some of those calls as primcalls. In that case, emit closures with
the primcalls.
* module/ice-9/psyntax.scm (resolve-identifier): There is a case where a
syntax object can resolve to itself. Prevent an infinite loop in that
case by continuing to resolve by name.
* module/ice-9/psyntax-pp.scm: Regenerate.
* test-suite/tests/syncase.test ("infinite loop bug"): Add a test.
* module/ice-9/command-line.scm (shell-usage): Add 'newline' call when
FMT is true.
(compile-shell-switches)[error]: Prepend "error: " and append "~%" to
FMT.
Use a lower-case message.
* libguile/memoize.c (memoize): Fix meta on subsequent case-lambda
clauses.
* module/ice-9/eval.scm (primitive-eval): Rewrite to compile expressions
to thunks, to avoid runtime dispatch cost.
* libguile/expand.c (convert_assignment): Handle creation of the default
lambda-case body here.
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval):
* libguile/memoize.h:
* libguile/memoize.c (MAKMEMO_BOX_REF, MAKMEMO_BOX_SET):
(MAKMEMO_TOP_BOX, MAKMEMO_MOD_BOX): Refactor all global var resolution
to go through "resolve". Add "box-ref" and "box-set!". Rename
memoize-variable-access! to %resolve-variable, and don't be
destructive.
* libguile/memoize.c (FULL_ARITY): Serialize "ninits" and the unbound
value instead of the init list.
(memoize): Adapt to FULL_ARITY changes. Remove LETREC case.
(unmemoize): Adapt to memoized code change.
* libguile/eval.c (BOOT_CLOSURE_PARSE_FULL): Adapt to parse ninits and
unbound instead of inits.
(eval): Lexical-ref can no longer raise an error.
(prepare_boot_closure_env_for_apply): Adapt to inits change.
* module/ice-9/eval.scm (primitive-eval): Adapt to ninits/unbound
change.
* libguile/expand.c (expand_named_let): Fix lambda-case creation to make
lists for opt and inits.
* module/ice-9/boot-9.scm (add-to-load-path): Remove argument from
%load-path (if it exists) before pushing. This also means that the
`elt' will always be at the front of %load-path.
* libguile/load.c (scm_i_mirror_backslashes): New function.
(scm_init_load_path): Call it to produce MS-Windows file names
with forward slashes.
(FILE_NAME_SEPARATOR_STRING): Define as "/" on all platforms.
* libguile/load.h (scm_i_mirror_backslashes): Add prototype.
* libguile/init.c (scm_boot_guile): Call scm_i_mirror_backslashes
on argv[0].
* libguile/filesys.c (scm_getcwd): Call scm_i_mirror_backslashes
on the directory name returned by getcwd.
* test-suite/tests/ports.test ("file name separators"): New test.
Fixes <http://bugs.gnu.org/17147>.
Reported by David Kastrup <dak@gnu.org>.
* module/ice-9/boot-9.scm (and, or): Use dotted tail instead of ellipsis
in patterns.
This yields a 20% improvement on the "read-string" benchmark.
* module/ice-9/rdelim.scm (read-string): Rewrite as a 'case-lambda',
with a tight loop around 'read-char', and without using
'read-string!'.
* test-suite/tests/rdelim.test ("read-string")["longer than 100 chars,
with limit"]: New test.
* benchmark-suite/benchmarks/ports.bm ("rdelim")["read-string"]: New
benchmark.
* module/ice-9/boot-9.scm (map): Rewrite to be recursive and pure
instead of iterative and effectful. At best this is faster; at worst
it is slower. In any case it resolves continuation-related issues.
* module/srfi/srfi-1.scm (fold): Specialize the two-arg case.
(map): Rewrite to be recursive.
* test-suite/tests/r5rs_pitfall.test (8.3): Update for new expected map
behavior.
* module/ice-9/eval.scm (primitive-eval): Expand out the call to
make-general-closure, so that make-general-closure becomes
well-known. Now eval has no more free variables!
* module/ice-9/match.upstream.scm (match-next): Inline a call to
"error", so the new CSE pass will see this case as a bailout.
* module/srfi/srfi-9.scm (throw-bad-struct): Reimplement as a syntax
rule, so that the CSE pass sees the "throw" call.
* module/ice-9/scm-style-repl.scm:
* module/ice-9/save-stack.scm: As the deprecated bindings have been
removed from the default environment, use #:export instead of
#:replace.
* module/ice-9/boot-9.scm (map):
* module/srfi/srfi-1.scm (map): Simplify the implementations to check
for list? beforehand. It's faster, and it will be needed if we decide
to go recursive.
* libguile/gc.c (scm_oom_fn, scm_init_gc): Install an out-of-memory
handler that raises an unwind-only out-of-memory exception.
(scm_gc_warn_proc, scm_init_gc): Install a warning proc that tries to
print to the current warning port, if the current warning port is a
file port.
(scm_gc_after_nonlocal_exit): New interface. Should be called after a
nonlocal return to potentially collect memory; otherwise allocations
could try to expand again when they should collect.
* libguile/continuations.c (scm_i_make_continuation):
* libguile/eval.c (eval):
* libguile/throw.c (catch):
* libguile/vm.c (scm_call_n): Call scm_gc_after_nonlocal_exit after
nonlocal returns.
* libguile/throw.c (abort_to_prompt, throw_without_pre_unwind): Rework
to avoid allocating memory.
(scm_report_out_of_memory): New interface.
(scm_init_throw): Pre-allocate the arguments for stack-overflow and
out-of-memory errors.
* module/ice-9/boot-9.scm: Add an out-of-memory exception printer.
* module/system/repl/error-handling.scm (call-with-error-handling): Add
out-of-memory to the report-keys set.
* libguile/gc-malloc.c (scm_realloc): Call scm_report_out_of_memory if
realloc fails.
* libguile/error.h:
* libguile/error.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_memory_error): Deprecate.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-out-of-memory: New test case.
* libguile/ports.c (scm_current_input_port, scm_current_output_port)
(scm_current_error_port): Fix declarations to C99.
(scm_current_warning_port, scm_set_current_warning_port): Rework to
use a C fluid, like scm_current_error_port.
(scm_init_ports): Initialize and define the warning port fluid.
* libguile/init.c (scm_init_standard_ports): Init the current warning
port.
* module/ice-9/boot-9.scm: Remove definitions for current-warning-port.
Instead, steal it from the boot objtable with port-parameterize!.
* module/ice-9/boot-9.scm (for-each):
* module/srfi/srfi-1.scm (for-each): Re-implement one-list case using an
explicit check for list? instead of the tortoise-hare thing. Seems to
be faster!
* module/ice-9/boot-9.scm (for-each): Fix detection of not-a-list in the
unrolled one-argument case.
* test-suite/tests/eval.test ("for-each"): Add a test.
* module/ice-9/boot-9.scm (catch): Signal an early error if the handler
or pre-unwind handler types aren't right. This is more important than
it was, given that we dispatch on type now when finding matching catch
clauses.
* libguile/vm.c (vm_expand_stack): Use the standard
scm_report_stack_overflow to signal stack overflow. This will avoid
running pre-unwind handlers.
* libguile/throw.h: Move scm_report_stack_overflow here.
* libguile/throw.c (catch): Define a version of catch in C.
(throw_without_pre_unwind): New helper. Besides serving as the
pre-boot "throw" binding, it allows stack overflow to throw without
running pre-unwind handlers.
(scm_catch, scm_catch_with_pre_unwind_handler)
(scm_with_throw_handler): Use the new catch in C.
(scm_report_stack_overflow): Moved from stackchk.c; throws an
unwind-only exception.
* libguile/stackchk.h:
* libguile/stackchk.c: Remove the scm_report_stack_overflow bits.
* libguile/throw.c (scm_init_throw): Define %exception-handler here.
* module/ice-9/boot-9.scm (%eh): Use the incoming %exception-handler,
and then delete it. This way we should be able to do unwind-only
exceptions from C.
* module/ice-9/boot-9.scm: Reimplement catch, throw, and
with-throw-handler in such a way that the exception handler is
threaded not through the exception-handling closures, but through a
data structure in the exception-handler fluid. This will allow us to
do unwind-only exception dispatch on stack overflow.
* module/ice-9/boot-9.scm: Move error-handling initialization after
psyntax initialization. Only "throw" is used before psyntax, and both
throw and catch have pre-boot variants in C.
* module/ice-9/pretty-print.scm (truncated-print): Use bytevector?
instead of uniform-vector?; the latter could be true for shared arrays
with non-zero lower bounds.
* libguile/weak-vectors.h:
* libguile/weak-vectors.c (scm_is_weak_vector, scm_c_weak_vector_length):
(scm_c_weak_vector_ref, scm_c_weak_vector_set_x): New interfaces for
dealing with weak vectors from C.
(scm_weak_vector_length, scm_weak_vector_ref, scm_weak_vector_set_x):
New Scheme interfaces to weak vectors; to be used instead of
vector-length, vector-ref, etc.
* module/ice-9/weak-vector.scm: Export the new interfaces.
* libguile/weaks.c (scm_is_weak_vector, scm_c_weak_vector_length):
(scm_c_weak_vector_ref, scm_c_weak_vector_set_x): New interfaces for
dealing with weak vectors from C.
(scm_weak_vector_length, scm_weak_vector_ref, scm_weak_vector_set_x):
New Scheme interfaces to weak vectors; to be used instead of
vector-length, vector-ref, etc.
* module/ice-9/weak-vector.scm: Export the new interfaces.
* doc/ref/api-memory.texi (Weak vectors): Document them.
* module/ice-9/boot-9.scm (define-values): Use 'generate-temporaries' to
generate a fresh name for 'dummy', to work around the lack of hygiene
for macro-introduced toplevel identifiers. Blackhole 'dummy' to avoid
keeping garbage alive. Add more comments.
