* module/ice-9/binary-ports.scm (bytevector-concatenate-reverse):
(bytevector-copy*): New helpers.

(init_bytevector_port_vars): Arrange to proxy to Scheme.
The goal was that, as part of a print operation, all nested prints of
contained data would be able to use the same parameters (e.g. write or
not), and also detect cycles, highlight objects, etc. The mechanism was
a heap-allocated data structure. However, given that:
1. Nobody accessed print states from Scheme
2. `write` and `display` should move to Scheme anyway, in order to be
suspendable
3. The "fancyp" and "highlight" options were unused
4. A simple stack-allocated data structure with a per-thread key could
do the trick just as well, without needing the weird freelist
structure
5. Ports-with-print-states were a source of bugs
In the end we switch print states to be something completely internal to
print.c. There are no more SCM print-state objects, and no more
ports-with-print-state.
* libguile/print.h: Remove print state from API.
* libguile/print.c (struct scm_print_state): Move definition here.
(scm_print_opts): Remove "highlight-prefix" and "highlight-suffix"
options, as they were not used.
(ENTER_NESTED_DATA): Remove "fancyp" case.
(init_print_state_key, get_print_state, push_print_state)
(maybe_push_print_state, pop_print_state): New facility to manage stack
of active print states.
(scm_iprin1, print_vector): No more fancyp.
(iprin1): Access "writingp" member directly. Don't make ports with
print states.
(scm_prin1): Manage print state stack.
(scm_iprlist): No more fancyp.
(scm_valid_oport_value_p): Remove; valid outports are SCM_OPOUTPORTP.

* libguile/deprecated.c:
* libguile/deprecated.h: Add deprecation shims for print states, as far
as that is possible.
Instead there is a module-definition-observer parameter.
* module/ice-9/boot-9.scm (module-definition-observer): New param.
* module/ice-9/deprecated.scm (module-defined-hook): Add deprecated
definition; install as definition observer.
* libguile/gc.c:
(scm_gc_event_listener_restarting_mutators):
(after_gc_async_thunk):
(scm_init_gc): Instead of using a hook for after-gc callbacks, just use
a list of thunks. Will allow us to move hooks to Scheme.
(add-after-gc-callback!, remove-after-gc-callback!): New functions.
* libguile/gc.h (scm_after_gc_hook): Remove.
* libguile/scmsigs.c (signal_delivery_thread): Update comment.
* module/statprof.scm (gcprof):
* test-suite/tests/gc.test ("gc"): Update to use new functions.
* module/ice-9/popen.scm (reap-pipe, open-pipe*): Instead of pumping a
guardian in the after-gc-hook, attach a finalizer. This will pump pipes
in a thread instead of needing to do it ourselves.
* libguile/srfi-14.c:
* module/srfi/srfi-14.scm: Arrange to define bindings here instead of in
the default environment.
* libguile/init.c:
* libguile/srfi-14.h: Fix so that srfi-14 can register an extension to
be loaded later.
* libguile/unidata_to_charset.awk: Rename private cs_letter_plus_digit

* module/ice-9/boot-9.scm (primitive-load): Define a version in Scheme
that uses read-syntax. This allows the expander to be able to access
source locations.
It was never documented, never used, and uses the gross assoc interface
to doubly-weak tables. Good-bye!
* module/ice-9/hcons.scm: Remove.
* am/bootstrap.am: Remove hcons from build.
* module/ice-9/poe.scm: Extract the one procedure from hcons that poe
uses, which notably doesn't have anything to do with hcons.
* module/ice-9/psyntax.scm (source-annotation): Only get source info
from syntax objects.
(strip): Don't attach source info.

* test-suite/tests/tree-il.test ("warnings"): Update tests that attach
source properties to use read-and-compile, or read-syntax.
This will allow for weak tables to be implemented partly in Scheme.
* module/ice-9/object-properties.scm: New file.
* am/bootstrap.am (SOURCES): Add new file.
* module/ice-9/boot-9.scm:
* module/ice-9/deprecated.scm (make-object-property*): Deprecate
make-object-property in default env and add a shim.

* module/scripts/frisk.scm (scripts):
* module/web/http.scm (web): Adapt users to import the new module.
* libguile/threads.h: Add join data directly on the thread instead of
using a Scheme-side weak table. It's less complicated and it will let
the weak table implementation use locks in Scheme; otherwise you would
have threads depending on weak tables and vice versa.
* libguile/threads.c (scm_trace_thread, guilify_self_1): Init and mark
the new members.
(thread_join_cond, thread_join_lock, thread_join_results)
(thread_init_joinable_x, thread_set_join_results_x): New accessors.
* module/ice-9/threads.scm (call-with-new-thread, join-thread): Use the
new accessors.
If that's what you want, you need to bring your own weak hash table on a
normal observer.
* module/ice-9/boot-9.scm (module): Remove weak-observers field.
(make-module, make-autoload-interface): Don't pass weak table to
constructor.
(module-observe-weak): Remove.

* module/ice-9/deprecated.scm (module-observe-weak): Dispatch to
module-observe.
* test-suite/tests/modules.test ("observers"): Adapt.
* module/ice-9/weak-vector.scm: New implementation, same interface.
* doc/ref/api-memory.texi (Weak vectors): Default weak vector value was
documented as empty list when it was actually unspecified, but #f is
most useful, so we change documentation and code to match.

try-module-autoload binding.

eventually.
* module/ice-9/save-stack.scm: Remove deprecation comment.

* module/ice-9/threads.scm: Export instead of replace bindings.
* module/language/bytecode.scm: Remove instruction-arity et al.
* module/language/tree-il/analyze.scm: Remove deprecated
unbound-variable-analysis and macro-use-before-definition-analysis.
* module/rnrs.scm: Fix syntax-case export now that module and value
namespaces are separate.
* module/system/base/language.scm (invalidate-compilation-cache!):
Remove.
* module/system/base/language.scm (*current-language*): Remove.
* module/ice-9/atomic.scm: Don't add-interesting-primitive! here.
* module/language/tree-il/primitives.scm
(*interesting-primitive-names*): Instead, import atomics here and
register the primitives as usual. This will let atomics be used earlier
in the boot graph.
Headed towards a 4.0. The binary format will change slightly but
incompatibly (e.g. renumbering of intrinsics). Having a new GC is
enough of a change to warrant a minor version bump, and it's been 5
years so why not go major.
* GUILE-VERSION (GUILE_EFFECTIVE_VERSION): Bump to 4.0.
(GUILE_MICRO_VERSION, GUILE_MINOR_VERSION): Bump to 3.9.0.
(LIBGUILE_INTERFACE_CURRENT, LIBGUILE_INTERFACE_AGE): Reset.
* meta/guile-4.0.pc.in:
* meta/guile-4.0-uninstalled.pc.in: Rename from guile-3.0.
* .gitignore: Ignore pkg-config files with 4.0 effective version.
* README: Update slightly.

version in paths.
* module/system/vm/assembler.scm (*bytecode-minor-version*):
* libguile/loader.h (SCM_OBJCODE_MAJOR_VERSION):
(SCM_OBJCODE_MINIMUM_MINOR_VERSION):
(SCM_OBJCODE_MINOR_VERSION): Use the same major objcode version for now
but bump the minor to 99.
* meta/guile.m4 (GUILE_PKG, GUILE_PROGS): Check for Guile 4.0.
* module/ice-9/boot-9.scm (%cond-expand-features): Add new cond-expand
features.
* module/ice-9/custom-ports.scm (make-custom-port): Code fails if
(fluid-ref %default-port-encoding) returns #f. In fact this was the
case why readline support on MSYS2 failed for guile 3.0.10, ref.
https://github.com/msys2/MSYS2-packages/issues/5079
But later used canonicalize-encoding is prepared to handle #f for
encoding. So allow encoding to also handle this case.

* module/ice-9/peg/string-peg.scm (peg-as-peg): Augment with rules for
hexadecimal digits, “\uXXX” for characters, “\t” for tabs, etc.

Modern PEG supports inversed class like `[^a-z]` that would get any
character not in the `a-z` range. This commit adds support for that and
also for a new `not-in-range` PEG pattern for scheme.
* module/ice-9/peg/codegen.scm (cg-not-in-range): New function.
* module/ice-9/peg/string-peg.scm: Add support for `[^...]`
* test-suite/tests/peg.test: Test it.
* doc/ref/api-peg.texi: Document accordingly.

This commit adds support for PEG as described in:
<https://bford.info/pub/lang/peg.pdf>
It adds support for the missing features (comments, underscores in
identifiers and escaping) while keeping the extensions (dashes in
identifiers, < and <--).
The naming system tries to be as close as possible to the one proposed
in the paper.
* module/ice-9/peg/string-peg.scm: Rewrite PEG parser.
* test-suite/tests/peg.test: Fix import
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* module/ice-9/psyntax.scm (define/override, define*/override): Use
instead of set! on globals.
($sc-dispatch): Renest. Will compile to the same thing as before.
* module/ice-9/psyntax-pp.scm: Regenerate.
