* libguile/Makefile.am (INSTANTIATE): New variable.
(install-data-hook): Use it.
* libguile/libguile-2.2-gdb.scm: Autoload (system vm debug).
Augment %load-path and %load-compiled-path, and reload (system base
types).
* module/system/base/types.scm: Remove #:hide to be 2.0-compatible.
Use (system syntax internal) conditionally when on 2.2.
* libguile/weak-table.c (scm_t_weak_table); Add last_gc_no member.
* libguile/weak-table.c (vacuum_weak_table): Only vacuum if we haven't
done so since the last GC.
(scm_c_weak_table_ref, scm_c_weak_table_put_x, scm_c_weak_table_remove_x)
(scm_c_weak_table_fold): Vacuum the weak table if needed.
(scm_weak_table_clear_x): Update last_gc_no flag, as no more vacuuming
will be needed.
This change should make weak tables work better with libgc, as the weak
components that need mark functions are smaller, so they don't overflow
the mark queue. Also this prevents the need to move disappearing
links.
* libguile/weak-table.c (scm_t_weak_entry): Change to be a hash table
chain entry.
(struct weak_entry_data, do_read_weak_entry, read_weak_entry): Read
out the key and value directly.
(GC_move_disappearing_link, move_disappearing_links, move_weak_entry):
Remove.
(scm_t_weak_table): Rename "entries" member to "buckets", and "size" to
"n_buckets".
(hash_to_index, entry_distance, rob_from_rich, give_to_poor): Remove.
(mark_weak_key_entry, mark_weak_value_entry): Mark a single link, and
the next link.
(mark_doubly_weak_entry): New kind.

(vacuum_weak_table): Adapt to new implementation.
(weak_table_ref, weak_table_put_x, weak_table_remove_x): Adapt.
(make_weak_table): Adapt.
(scm_weak_table_clear_x): Actually unregister the links to prevent a
memory leak.
(scm_c_weak_table_fold): Collect items in an alist, then fold outside
the lock.
(scm_weak_table_prehistory): Initialize doubly_weak_gc_kind.
* module/ice-9/arrays.scm (array-print-prefix): New private function.
* libguile/arrays.c (scm_i_print_array): Reuse (array-print-prefix) from
(ice-9 arrays). Make sure to release the array handle.
* module/ice-9/pretty-print.scm (truncated-print): Support
bitvectors.
Don't try to guess the array prefix but call array-print-prefix from
(ice-9 arrays) instead.
Fix call to print-sequence to support non-zero lower bound arrays.
* test-suite/tests/arrays.test: Test that arrays print properly.
* test-suite/tests/print.test: Test truncated-print with bitvectors,
non-zero lower bound arrays.
* module/ice-9/arrays.scm (array-copy): New function, export.
* module/Makefile.am: Install (ice-9 arrays).
* doc/ref/api-data.texi: Add documentation for (ice-9 arrays).
* libguile/quicksort.i.c: Use signed bounds throughout.
* libguile/sort.c (scm_restricted_vector_sort_x): Fix error calls. Fix
calls to quicksort.

match the original data. Test cases for non-zero base index arrays for
sort, sort!, and stable-sort!.
* benchmark-suite/benchmarks/uniform-vector-read.bm:
Remove; uniform-vector-read! and uniform-vector-write were deprecated
in 2.0 and are have been removed in 2.1.
* benchmark-suite/benchmarks/bytevector-io.bm: New benchmark.
* benchmark-suite/Makefile.am: Run the new benchmark.
* libguile/array-handle.c (initialize_vector_handle): Set both element
pointers to NULL if the vector is empty.
* libguile/array-map.c (racp): Ignore immutability if destination is
empty.
* test-suite/tests/sort.test: Check empty/mutable/immutable vectors with
sort!.
* test-suite/tests/array-map.test: Check array-copy! with
empty/immutable destination.

* libguile/fports.c (revealed_ports, revealed_lock): Remove.
(scm_revealed_count): Just return 'SCM_REVEALED (port)'.
(scm_set_port_revealed_x, scm_adjust_port_revealed_x): Remove
REVEALED_PORTS manipulation.
(fport_close): Do nothing when SCM_REVEALED (port) > 0.
* libguile/fports.h (scm_t_fport): Adjust comment; make 'revealed'
unsigned.
* libguile/ports.c (do_close): Call 'close_port' instead of
'scm_close_port'.
(scm_close_port): Rename to...
(close_port): ... this. Add 'explicit' parameter. Clear 'revealed'
field when PORT is a file port and EXPLICIT is true.
(scm_close_port): Call 'close_port'.
* test-suite/tests/ports.test ("close-port & revealed port")
("revealed port fdes not closed"): New tests.
This fixes a bug when using ",break":
system/vm/traps.scm:127:31: system/vm/traps.scm:127:31: In procedure <: Wrong type: #f
* module/system/vm/traps.scm (frame-matcher): Check whether END is
true.
* 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/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.
* NEWS: Add entry.
* libguile/struct.c: Replace uses of scm_make_struct with
scm_make_struct_no_tail or scm_c_make_struct.
(scm_make_struct_no_tail): Move this function to C instead of Scheme
to be able to deprecate scm_make_struct.
* libguile/struct.h (scm_make_struct_no_tail): New public declaration.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_make_struct): Deprecate.
* libguile/print.c:
* libguile/procs.c:
* libguile/stacks.c: Replace uses of scm_make_struct with
scm_make_struct_no_tail.
* test-suite/tests/coverage.test:
* test-suite/tests/structs.test: Use make-struct/no-tail instead of
make-struct.
* NEWS: Add entry.
* 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.
* module/web/client.scm (tls-wrap): Use get-bytevector-some instead of
get-bytevector-n, to prevent Guile from attempting to read more bytes
than are available. Normally trying to read data on a shut-down
socket is fine, but but gnutls issues an error if you attempt to read
data from a shut-down socket, and that appears to be a security
property. Fixes HTTPS requests whose responses are smaller than the
port buffer.
* doc/ref/srfi-modules.texi (SRFI-19): SRFI-19 specifies proleptic use
of the Gregorian calendar, so it was incorrect of the documentation to
describe the code as erroneous in doing so. Rewrite the caution more
neutrally, and move it to the section about the "date" structure, where
it seems most relevant.
* libguile/eq.c (scm_equal_p, scm_raw_ihash): Add cases for syntax
objects, which should be comparable with equal?.
* test-suite/tests/syntax.test ("syntax objects"): Add tests.
* configure.ac: Check for GC_is_heap_ptr, added after libgc 7.2.
* libguile/pairs.h (GC_is_heap_ptr): Define a shim for GC_is_heap_ptr,
inside BUILDING_LIBGUILE so as not to expose it to users.
