* libguile/struct.c (scm_make_struct_layout): Remove support for opaque
slots.
(set_vtable_layout_flags): Remove opaque slots, and make the "switch"
total.
(scm_is_valid_vtable_layout): Remove opaque slots.
(scm_struct_ref, scm_struct_set_x): Remove case for opaque slots.
* module/oop/goops.scm (opaque-slot?, read-only-slot?): New helpers.
(allocate-slots): Protect opaque and read-only slots by wrapping the
slot accessors instead of relying on struct permissions.
(%compute-layout): Remove opaque-slot case.
* libguile/struct.c (scm_make_struct): Remove support for tail arrays
and self slots.
(set_vtable_layout_flags): Always initialize the nfields member.
(scm_is_valid_vtable_layout): Remove support for tail arrays and self
slots.
(scm_i_struct_inherit_vtable_magic): No need to issue deprecation
warning for self slots, as they are no longer supported.
(scm_struct_init): Remove support for tail arrays and self slots.
(scm_c_make_structv): Throw an exception if n_tail is not 0.
(scm_allocate_struct): Adapt to scm_struct_init change.
(scm_i_make_vtable_vtable): Initialize slots manually, to avoid
relying on an already-initialized nfields member.
(scm_struct_ref, scm_struct_set_x): Simplify.
* module/oop/goops.scm: As we now rely on nfields being valid, when
recalculating slots during boot we need to avoid resetting nfields of
<class>, even temporarily, as that would prevent any further access to
<class>!
* libguile/print.h (SCM_PRINT_STATE_LAYOUT): Use a normal slot instead
of a self slot.
* libguile/print.c (make_print_state): Initialize "handle" slot
manually.
* libguile/struct.c (issue_deprecation_warning_for_self_slots): New
helper, called when making vtables to issue deprecation warnings for
"self" slots. Avoids warning for the "self" slot that's part of the
fixed vtable slots.
(scm_i_struct_inherit_vtable_magic): Call
issue_deprecation_warning_for_self_slots.
* doc/ref/api-data.texi (Vtables, Structure Basics): Remove references
to self slots.

* test-suite/tests/coverage.test:
* test-suite/tests/structs.test: Use make-struct/no-tail instead of
make-struct.
* NEWS: Add entry.
* doc/ref/goops.texi (Redefinable Classes): New subsection.
(Default Class Redefinition Behaviour)
(Changing the Class of an Instance): Update for class redefinition
change.
* NEWS: Add 2.3.0 section.
* module/oop/goops.scm (fold-class-slots): Remove "redefined" field from
class objects. Redefinable classes are now handled in a layer on top
of GOOPS core.

Remove "self" field. Renumber the other fields.
* module/oop/goops.scm (<self-slot>): Remove.
(fold-class-slots): Adapt for "self" slot removal. Adapt all users.
(class-redefinition): Now that there is no "self" slot to update, use
%modify-instance instead of %modify-class.
* libguile/goops.c (class_self): Remove.
(scm_sys_modify_class): Remove.

here.

comment.
* libguile/modules.c (scm_post_boot_init_modules): Update for new format
of struct vtable references.
* libguile/struct.c (scm_i_alloc_struct): Update to include slots
directly, instead of being indirected by an embedded pointer.
(scm_c_make_structv, scm_allocate_struct, scm_i_make_vtable_vtable):
Adapt to pass vtable bits as argument to scm_i_alloc_struct, not
vtable data bits.
(scm_init_struct): Remove two-word displacement from libgc.
* libguile/struct.h: Update comment.
(SCM_STRUCT_SLOTS, SCM_STRUCT_DATA): Update definitions.
(SCM_STRUCT_VTABLE_DATA, SCM_STRUCT_VTABLE_SLOTS): Remove.

(SCM_VTABLE_FLAG_GOOPS_NEEDS_MIGRATION): New flags.
(SCM_CLASSF_GOOPS_VALID, SCM_CLASSF_GOOPS_OR_VALID): Remove obsolete
definitions.
(SCM_IS_A_P): Use the scm_class_of function.
* libguile/goops.c (var_class_of_obsolete_indirect_instance): Rename
from var_migrate_instance.
(scm_is_generic, scm_is_method, scm_sys_init_layout_x): Use
scm_class_of instead of the SCM_CLASS_OF macro.
(get_indirect_slots): New helper.
(scm_class_of): This patch moves us in a direction where we won't be
able to separately address a struct's data and its identity.
Therefore to check whether a class needs migration, we check an
embedded pointer from a slot instead of the vtable data.
(scm_sys_struct_data): Remove this temporary function.
(scm_sys_modify_instance): Update to swap slot values instead of the
data pointers themselves.
(scm_sys_modify_class): Use scm_sys_modify_instance.
(scm_sys_goops_loaded): Capture class-of-obsolete-indirect-instance
instead of migrate-instance.
(scm_init_goops_builtins): Don't export the "valid" flag any more;
export instead the "indirect" and "needs-migration" flags.

FIXME.

being.

(indirect-slots-need-migration?): New helpers.
(<class>, <slot>, %class-slot-definition, initialize): Remove use of
vtable-flag-goops-valid.
(define-class): Always push redefined values through
`class-redefinition'.
(<redefinable-class>): New public definition. Use it as a metaclass
for redefinable classes. Provide a compute-slots function that
declares the indirect slots mechanism. Add the "indirect" flag to
instances of <redefinable-class>. Create indirect-slots objects for
instances of those classes as part of their allocate-instance.
(change-object-class, class-of-obsolete-indirect-instance): Update for
new representation change.
* test-suite/tests/goops.test ("object update"): Add #:metaclass
<redefinable-class> to all redefinable classes. For the "hell" test,
make the new classes with class-direct-slots, not class-slots; this
was an error in the test.
* libguile/goops.c (scm_class_of): Call out directly to the GOOPS-local
`migrate-instance' if an instance needs to migrate.
(scm_sys_struct_data): New internal temporary function used by the
Scheme `migrate-instance'. Exorcise the evil one from the old C
implementation.
* libguile/goops.h (scm_change_object_class): Remove function used only
internally in GOOPS.
* module/oop/goops.scm (migrate-instance): Implement the
hell/purgatory/etc logic in Scheme instead of C.
* libguile/r6rs-ports.c (scm_put_bytevector, scm_unget_bytevector): When
three arguments (port bv start) are provided, allow start to be equal to
the length of the bytevector, resulting in a zero-length write.
* libguile/filesys.c (scm_i_relativize_path): When DIR is a prefix of
SCANON, make sure DIR ends with a separator or SCANON starts with a
separator.
* test-suite/tests/ports.test (%temporary-directory): New variable.
("%file-port-name-canonicalization")["relative canonicalization with
common prefixes"]: New test.
This is a followup to commit 42f7c01e0a.
Reported by Adriano Peluso <catonano@gmail.com>.
* doc/ref/api-foreign.texi (Foreign Types): Add missing entries for
'short' and 'unsigned-short'.
Based on a patch by Daniel Hartwig <mandyke@gmail.com>.
* NEWS: Update.
* doc/ref/web.texi (URIs): Fragments are properly part of a URI, so
remove the incorrect note. Add documentation on URI subtypes.
* module/web/uri.scm (uri-reference?): New base type predicate.
(uri?, relative-ref?): Specific predicates.
(validate-uri-reference): Strict validation.
(validate-uri, validate-relative-ref): Specific validators.
(build-uri-reference, build-relative-ref): New constructors.
(string->uri-reference): Rename from string->uri.
(string->uri, string->relative-ref): Specific constructors.
(uri->string): Add #:include-fragment? keyword argument.
* module/web/http.scm (parse-request-uri): Use `build-uri-reference',
and result is a URI-reference, not URI, object. No longer infer an
absent `uri-scheme' is `http'.
(write-uri): Just use `uri->string'.
(declare-uri-header!): Remove unused function.
(declare-uri-reference-header!): Update. Rename from
`declare-relative-uri-header!'.
* test-suite/tests/web-uri.test ("build-uri-reference"):
("string->uri-reference"): Add.
("uri->string"): Also tests for relative-refs.
* test-suite/tests/web-http.test ("read-request-line"):
("write-request-line"): Update for no scheme in some URIs.
("entity headers", "request headers"): Content-location, Referer, and
Location should also parse relative-URIs.
* test-suite/tests/web-request.test ("example-1"): Expect URI-reference
with no scheme.
* include/lightning/jit_private.h, lib/lightning.c: Add a
second pass from start when computing register live ranges.
This should be used temporarily, and is required for certain
loop constructs, with several consecutive blocks not referencing
a live register.
