For some systems, ECONNABORTED is a failure condition for reading from closed sockets.
* test-suite/tests/00-repl-server.test (HTTP inter-protocol attack): modified
* module/ice-9/psyntax.scm (syntax?): Only recognize legacy syntax
objects if the new allow-legacy-syntax-objects? parameter is true.
* module/ice-9/boot-9.scm (allow-legacy-syntax-objects?): New
parameter.
* doc/ref/api-macros.texi (Syntax Transformer Helpers): Document the
horrible situation with legacy syntax objects.
* NEWS: Add entry.
* module/ice-9/psyntax.scm (make-syntax-object): Change to make
new-style syntax objects.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/compile-psyntax.scm (squeeze-syntax-object): Change to be
functional.
(squeeze-constant): Likewise.
(squeeze-tree-il): Likewise.
(translate-literal-syntax-objects): New pass. The compiler can embed
literal syntax objects into compiled objects, but syntax can no longer
be read/written; otherwise users could forge syntax objects. So for
the bootstrap phase, rewrite literal constants to calls to
make-syntax.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(DOT_X_FILES, DOT_DOC_FILES, noinst_HEADERS): Add syntax.c and
syntax.h.
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/goops.c (class_syntax, scm_class_of, scm_goops_early_init):
* libguile/init.c (scm_init_guile):
* libguile/print.c (iprin1):
* libguile/tags.h (scm_tc7_syntax):
* module/oop/goops.scm (<syntax>):
* module/system/base/types.scm (%tc7-syntax, cell->object):
* module/system/vm/disassembler.scm (code-annotation): Wire up the new
data type.
* libguile/syntax.c:
* libguile/syntax.h: New files.
* module/ice-9/boot-9.scm: Move new definitions to (system syntax
internal).
* module/system/syntax.scm (print-syntax): New helper.
* module/system/vm/assembler.scm (statically-allocatable?)
(intern-constant, link-data): Arrange to be able to write syntax
objects into images.
* module/language/cps/types.scm (&syntax): New type. Remove
&hash-table; it was never detected, an internal binding, and we need
the bit to avoid going into bignum territory.
* module/ice-9/psyntax.scm (%syntax-module): Rename from syntax-module
in order to make room for a new syntax-module primitive binding.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/boot-9.scm: Push syntax bindings into an internal
module.
* module/system/syntax.scm: New file.
* module/Makefile.am (SOURCES): Add system/syntax.scm.
* GUILE-VERSION (GUILE_MINOR_VERSION, GUILE_MICRO_VERSION): Bump.
(LIBGUILE_INTERFACE_CURRENT): Incrememt to indicate that we now have a
defined libtool ABI "interface" of 1, that we support no other
interface (yet), and that this is the 0th revision of that interface.
* configure.ac: Use detected endianness and word size to automatically
select which set of prebuilt binaries to use.
* meta/build-env.in (top_builddir):
* meta/uninstalled-env.in (top_builddir): Update to use
SCM_PREBUILT_BINARIES for prebuilt entry in GUILE_LOAD_COMPILED_PATH.
* prebuilt/32-bit-big-endian:
* prebuilt/32-bit-little-endian:
* prebuilt/64-bit-little-endian: New links.
* prebuilt/x86_64-pc-linux-gnu: Remove this link now that it's unneeded.
* module/language/cps/effects-analysis.scm (expression-effects): Prompts
cause &all-effects. I tried to limit this change to CSE but it was
actually LICM that was borked, so better to be conservative
* test-suite/tests/control.test ("escape-only continuations"): Add
test.
* libguile/finalizers.c (async_gc_finalizer):
(scm_i_register_async_gc_callback): Replace "weak gc callback"
mechanism with "async gc callback" mechanism. Very similar but the
new API is designed to be called a bounded number of times, to avoid
running afoul of libgc heuristics.
* libguile/weak-list.h: New internal header.
* libguile/Makefile.am (noinst_HEADERS): Add weak-list.h.
* libguile/weak-set.c (vacuum_all_weak_sets):
(scm_c_make_weak_set, scm_init_weak_set):
* libguile/weak-table.c (vacuum_all_weak_tables):
(scm_c_make_weak_table, scm_init_weak_table): Arrange to vacuum all
weak sets from a single async GC callback, and likewise for weak
tables.
Thanks to Ludovic Courtès for tracking this bug down!
* libguile/atomics-internal.h (scm_atomic_subtract_uint32):
(scm_atomic_compare_and_swap_uint32, scm_atomic_set_pointer):
(scm_atomic_ref_pointer, scm_atomic_set_scm):
(scm_atomic_ref_scm, scm_atomic_swap_scm):
(scm_atomic_compare_and_swap_scm): Use C11 atomic types if we have
loaded C11 stdatomic.h.
* doc/ref/scheme-ideas.texi: the some way -> the same way
* doc/ref/scheme-intro.texi: Use @math inside a texinfo command (turns out
$math$ is not processed in this context and thus is not rendered correctly).
* doc/ref/vm.texi (Inlined Scheme Instructions): Add string-set!.
* libguile/vm-engine.c (string-set!): New opcode.
* module/ice-9/rdelim.scm (read-string): Reimplement in terms of a
geometrically growing list of strings, to reduce total heap usage when
reading big files.
* module/language/cps/compile-bytecode.scm (compile-function): Add
string-set! support.
* module/language/cps/types.scm (string-set!): Update for &u64 index.
* module/language/tree-il/compile-cps.scm (convert): Unbox index to
string-set!.
* module/system/vm/assembler.scm (system): Export string-set!.
This bug was introduced by 35a9059250.
* module/language/cps/specialize-numbers.scm (specialize-operations):
Check that both operands are real as a condition for
specialize-f64-comparison.
* test-suite/tests/numbers.test: Add test.
* module/language/cps/compile-bytecode.scm (compile-function): Check for
fallthrough after $kclause too; possible to need to jump if clause
tails are contified.
* module/language/cps/contification.scm (compute-contification-candidates):
Enable inter-clause contification.
* module/language/cps/compile-bytecode.scm (compile-function):
* module/language/cps/slot-allocation.scm ($allocation)
(lookup-nlocals, compute-frame-size, allocate-slots): Adapt to
have one frame size per function, for all clauses.
* module/system/vm/linker.scm (*lcm-page-size*): Rename
from *page-size*, change to 64 KB.
* libguile/loader.c (load_thunk_from_memory): Only require page size
alignment, knowing that although Guile might emit ELF with 64k
alignment, it only really needs page alignment.
* libguile/fluids.h (struct scm_dynamic_state): Add thread_local_values
table. Thread locals are flushed to a separate thread-local table.
The references are strong references since the table never escapes the
thread.
(scm_make_thread_local_fluid, scm_fluid_thread_local_p): New
functions.
* libguile/fluids.c (FLUID_F_THREAD_LOCAL):
(SCM_I_FLUID_THREAD_LOCAL_P): New macros.
(restore_dynamic_state): Add comment about precondition.
(save_dynamic_state): Flush thread locals.
(scm_i_fluid_print): Print thread locals nicely.
(new_fluid): Add flags arg.
(scm_make_fluid, scm_make_fluid_with_default, scm_make_unbound_fluid):
Adapt.
(scm_make_thread_local_fluid, scm_fluid_thread_local_p): New
functions.
(fluid_set_x): Special flushing logic for thread-locals.
(fluid_ref): Special cache miss logic for thread locals.
* libguile/stacks.c (scm_init_stacks):
* libguile/throw.c (scm_init_throw): %stacks and %exception-handler are
thread-locals.
* libguile/threads.c (guilify_self_2): Init thread locals table.

* doc/ref/api-control.texi (Fluids and Dynamic States): Add link to
Thread-Local Variables.
* doc/ref/api-scheduling.texi (Thread Local Variables): Update with real
thread-locals.
* NEWS: Update.
Fixes <http://bugs.gnu.org/20272>.
* module/ice-9/boot-9.scm (module-generate-unique-id!)
(module-gensym): New procedures.
(module): Add 'next-unique-id' field.
(the-root-module): Inherit 'next-unique-id' value from early stub.
(make-module, make-autoload-interface): Adjust calls to
module-constructor.
* module/ice-9/psyntax.scm (gen-label, new-mark): Generate unique
identifiers from the module name and the per-module unique-id.
(build-lexical-var, generate-temporaries): Use
'module-gensym' instead of 'gensym'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/language/tree-il/fix-letrec.scm (fix-letrec!): Use
'module-gensym' instead of 'gensym'.
* module/system/base/syntax.scm (define-record): Likewise.
(transform-record): Likewise.
