* module/ice-9/boot-9.scm (duplicate-handlers): Use module-variable
instead of module-local-variable in the warn-override-core, first, and
last handlers. Fixes#47084 mostly, though relative to pre-3.0 there is
still a difference in that a module needs to explicitly declare which
bindings are intended as replacements -- a binding being a replacement
is a property of the module in 3.0, rather than the variable as was the
case before 3.0.
Instead of defining a separate module, given that "read" calls are quite
all over the place, we're just going to replace the boot "read" binding
with read.scm. This way, we'll be able to remove support for reader
options in the boot reader, as it will only ever be used for a finite
set of files.
* NEWS: Update.
* module/Makefile.am (ice-9/boot-9.go): Depend on read.scm.
(SOURCES):
* am/bootstrap.am (SOURCES): Don't build a ice-9/read.go, as we include
it.
* module/ice-9/boot-9.scm (read-syntax): Define here, as "include" now
uses it.
(read-hash-procedures, read-hash-procedure, read-hash-extend): New
procedures. Will replace C variants.
(read, read-syntax): Include read.scm to define these.
* module/ice-9/psyntax-pp.scm (include): Regenerate.
* module/ice-9/psyntax.scm (include): Use read-syntax, so we get better
source information.
* module/ice-9/read.scm (let*-values): New local definition, to avoid
loading srfi-11.
(%read): Use list->typed-array instead of u8-list->bytevector.
* module/language/scheme/spec.scm: Remove (ice-9 read) import;
read-syntax is there in the boot environment
* libguile/syntax.c (scm_make_syntax): Add optional "source" argument.
Note that this function is internal.
(scm_syntax_source): New function, replacing definition in boot-9.scm.
* libguile/syntax.h: Add new declarations.
* module/ice-9/psyntax-pp.scm:
* module/ice-9/psyntax.scm (source-annotation): For syntax objects, the
source annotation comes direct from the syntax object.
* module/system/vm/assembler.scm (link-data, intern-constant): Write
5-word syntax objects.
* module/ice-9/boot-9.scm (%auto-compilation-options): Add
use-before-definition and non-idempotent-definition.
* module/language/tree-il/analyze.scm (<use-before-def-info>): New
analysis info.
(make-use-before-definition-analysis): New function.
(goops-toplevel-definition): Move down.
(unbound-variable-analysis, macro-use-before-definition): Remove, as
they are subsumed by use-before-def. There are some deprecated
bindings though.
(make-analyzer): Rework to allow for use-before-def analysis to handle
multiple
* module/system/base/message.scm (%warning-types): Add handlers for the
new warning types.
* test-suite/tests/tree-il.test: Add tests.
* doc/ref/api-evaluation.texi (Compilation): Update.
This is similar to 0bb980f12 (New function: install-r6rs!, 2019-09-25)
which accepts .sls extension for r6rs. In r7rs, most portable libraries
use .sld.
* module/ice-9/boot-9.scm (install-r7rs!): Update %load-extensions.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* module/Makefile.am (ice-9/boot-9.go, NOCOMP_SOURCES): Add
r7rs-libraries.

* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/r7rs-libraries.scm: New file.
* module/scheme/base.scm (r7:include, r7:include-ci): Fix mistaken use
of core "include". Use include-ci from core.
(features): Remove features that are already part of core.
* NEWS: Update.
* doc/ref/api-modules.texi (Creating Guile Modules): Document
#:re-export-and-replace.
* module/ice-9/boot-9.scm (module-replacements): New module field.
(make-module, make-autoload-interface): Initialize replacements to an
empty hash table.
(resolve-interface): Propagate replacement info when making custom
interfaces.
(define-module): Parse a #:re-export-and-replace keyword arg.
(define-module*): Handle #:re-export-and-replace.
(module-export!, module-re-export!): Add a keyword arg to indicate
whether to replace or not.

* module/srfi/srfi-34.scm (srfi): Update to #:re-export-and-replace
raise-continuable as raise.
* module/ice-9/boot-9.scm (exception-kind, exception-args): Export.
* module/ice-9/exceptions.scm (exception-kind, exception-args):
Re-export.
* module/srfi/srfi-18.scm: Rewrite exception support in terms of core
exceptions, not SRFI-34/35.
* test-suite/tests/srfi-18.test: Since Guile doesn't expose the current
exception handler as such, SRFI-18 captures it using delimited
continuations. This means that we can't compare the result
of (current-exception-handler) with the installed handler using eq?,
even though the procedures are indeed equivalent. So, instead test
handler behavior.
* libguile/exceptions.c:
* libguile/exceptions.h: New files.
* libguile.h: Add exceptions.h.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):

with-exception-handler / raise-exception.
* libguile/throw.h: Use data types from exceptions.h. Move
scm_report_stack_overflow and scm_report_out_of_memory to
exceptions.[ch].

&programming-error, &non-continuable, raise-exception, and
with-exception-handler from boot-9.
(make-quit-exception, guile-quit-exception-converter): New exception
converters.
(make-exception-from-throw): Override core binding.
* test-suite/tests/eval.test ("inner trim with prompt tag"): Adapt to
"with-exception-handler" being the procedure on the stack.
("outer trim with prompt tag"): Likewise.
* test-suite/tests/exceptions.test (throw-test): Use pass-if-equal.
* module/srfi/srfi-34.scm: Reimplement in terms of core exceptions, and
make "guard" actually re-raise continuations with the original "raise"
continuation.

make-record-type. Incidentally the result is that instances of
derived R6RS record types are now flat instead of nested.
* test-suite/tests/r6rs-records-procedural.test
("make-record-type-descriptor"): Relax a couple condition type checks,
while we redo the exception system.
* module/ice-9/boot-9.scm (make-record-type): Allow (mutable NAME)
or (immutable NAME) as a field name, and record field mutability in a
bitfield.
(record-modifier): Throw an error if the field isn't mutable.
* test-suite/tests/records.test ("records"): Add tests.
* doc/ref/api-data.texi (Records): Update.
* module/ice-9/boot-9.scm (make-record-type): Validate that the fields
are a unique list of symbols. Deprecate passing a string as a type
name.
* module/system/base/syntax.scm (define-record): Update to pass a symbol
as a type name.
* test-suite/tests/records.test (rtd-foo, rtd-fŏŏ, "records"): Adapt to
make record types with symbol names.
* module/ice-9/boot-9.scm (make-record-type): Don't allow subtyping of
final types.
(%record-type-error): Remove helper.
(record-accessor, record-modifier): Use computed record type
predicate, to allow for subtyping.
(define-record-type): Adapt to %record-type-error going away; these
types are final so no accessor adaptation is needed.
* test-suite/tests/records.test: Add tests.
* doc/ref/api-data.texi (Records): Update.
* module/ice-9/boot-9.scm (record-type-vtable): Add slots for "flags"

accessors.
(make-record-type): Take #:final? and #:parent keyword arguments.
(record-constructor): Delegate to record-type-constructor.
(record-predicate): For non-final types --types that can be extended
by subtyping -- implement an O(1) type predicate.

parent fields.
* module/ice-9/boot-9.scm (else, =>, ..., _): New definitions. These
are specified by the r6rs and the r7rs.

definitions.
* module/rnrs/base.scm:
* module/rnrs.scm: Re-export aux syntax.
* doc/ref/api-modules.texi (Declarative Modules): New subsection.
* module/ice-9/boot-9.scm (module): Change eval-closure slot, which was
deprecated and unused, to be a "declarative?" slot, indicating that
definitions from the module are declarative.
(user-modules-declarative?): New parameter.
(make-fresh-user-module): Set declarative according to parameter.
(define-module*, define-module): Add #:declarative? keyword argument,
defaulting to the value of user-modules-declarative? parameter when

'macro-use-before-definition'.
Fixes <https://bugs.gnu.org/30602>.
Previously, when compiling files in parallel like Guix does, threads
would be concurrently inserting, rehashing, and reading the submodule
hash table of module (). Thus, some threads would sometimes see an
inconsistent state, leading to errors such as:
Module named (system repl debug) does not exist
* module/ice-9/boot-9.scm (call-with-module-autoload-lock): Move higher
in the file.
(module-name): Use it around call to 'nested-define-module!'.
(resolve-module): Wrap the whole thing in 'call-with-module-autoload-lock'.
Fixes <https://bugs.gnu.org/31878>.
* module/ice-9/boot-9.scm (call-with-module-autoload-lock): New procedure.
(try-module-autoload): Wrap body in 'call-with-module-autoload-lock'.
* module/ice-9/threads.scm: Set (@ (guile) call-with-module-autoload-lock).
