* module/ice-9/boot-9.scm (module-defer-observers): Instead of being a
global flag, change to be a parameter.
(module-defer-observers-mutex, module-defer-observers-table): Remove.
(module-modified): Adapt.
(call-with-deferred-observers): Adapt. Allow nested called.
* doc/ref/vm.texi (Inlined Atomic Instructions): New section.
* libguile/vm-engine.c (VM_VALIDATE_ATOMIC_BOX, make-atomic-box)
(atomic-box-ref, atomic-box-set!, atomic-box-swap!)
(atomic-box-compare-and-swap!): New instructions.
* libguile/vm.c: Include atomic and atomics-internal.h.
(vm_error_not_a_atomic_box): New function.
* module/ice-9/atomic.scm: Register primitives with the compiler.
* module/language/cps/compile-bytecode.scm (compile-function): Add
support for atomic ops.
* module/language/cps/effects-analysis.scm: Add comment about why no
effects analysis needed.
* module/language/cps/reify-primitives.scm (primitive-module): Add case
for (ice-9 atomic).
* module/language/tree-il/primitives.scm (*effect-free-primitives*):
(*effect+exception-free-primitives*): Add atomic-box?.
* module/system/vm/assembler.scm: Add new instructions.
* test-suite/tests/atomic.test: Test with compilation and
interpretation.
* module/ice-9/psyntax.scm (include-from-path): Canonicalize result of
%search-load-path. Otherwise a relative path passed to `include'
would be treated as relative to the directory of the file that
contains the `include-from-path'. Fixes#21347.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/boot-9.scm (define-module*): Leaving off #:duplicates
defaults to installing the duplicate binding handlers specified in the
manual, not the value of some other dynamic parameter.
(default-duplicate-binding-procedures):
(default-duplicate-binding-handler): Instead of closing over a
separate fluid, close over the handlers of the current module. That
way when a user does (default-duplicate-binding-handler ...) in a
script, then it applies to the right module.
* libguile/load.c (load_thunk_from_path, try_load_thunk_from_file): New
functions.
(search_path): Simplify.
(scm_primitive_load_path, scm_init_eval_in_scheme): Use the new
functions to load compiled files.
* module/ice-9/boot-9.scm (load-in-vicinity): Skip invalid .go files.
Inspired by a patch from Jan Nieuwenhuizen <janneke@gnu.org>.

* module/ice-9/ports.scm (port-encode-char): Export port-encode-char to
the internals module.
* module/ice-9/sports.scm (put-char): New function.
(port-bindings): Add put-char and put-string.
* module/ice-9/suspendable-ports.scm: Rename from ice-9/sports.scm, and
adapt module names. Remove exports that are not related to the
suspendable ports facility; we want people to continue using the port
operations from their original locations. Add put-string to the
replacement list.
* module/Makefile.am: Adapt to rename.
* test-suite/tests/suspendable-ports.test: Rename from sports.test.
* test-suite/Makefile.am: Adapt to rename.
* module/ice-9/textual-ports.scm (unget-char, unget-string): New
functions.
* doc/ref/api-io.texi (Textual I/O, Simple Output): Flesh out
documentation.
(Line/Delimited): Undocument write-line, read-string, and
read-string!. This is handled by (ice-9 textual-ports).
(Bytevector Ports): Fix duplicated section.
(String Ports): Move the note about encodings down to the end.
(Custom Ports): Add explanatory text. Remove mention of C functions;
they should use the C port interface.
(Venerable Port Interfaces): Add text, and make documentation refer to
recommended interfaces.
(Using Ports from C): Add documentation.
(Non-Blocking I/O): Document more fully and adapt to suspendable-ports
name change.
* libguile/ports.h (scm_put_char):
* libguile/ports.c (scm_put_char): New function.
(scm_put_string): Add docstrings, and expose to the internal ports
module.
* module/ice-9/ports.scm (put-char, put-string): Expose these bindings
only through the internals module.
* module/ice-9/ports.scm: Export port-encode-chars and
port-clear-stream-start-for-bom-write via the internals module.
* module/ice-9/sports.scm (put-string): New function.
* libguile/ports.c (scm_port_line_buffered_p): New function.
* module/ice-9/ports.scm: Plump port-line-buffered? and
port-auxiliary-write-buffer through to the internals module
* module/ice-9/sports.scm: Export read-line, %read-line, and
read-delimited. Add these latest three to install-sports!, and fix
install-sports! if the current module isn't (ice-9 sports).
* test-suite/tests/sports.test: Use install-sports! instead of lexical
bindings, to allow us to nicely frob bindings in rdelim. Include
rdelim tests.
* doc/ref/guile.texi: Add 2016 to user-visible copyright notice.
* module/ice-9/command-line.scm (version-etc): Bump 'copyright-year' to
2016.
* module/system/repl/common.scm (*version*): Add 2016 to the range of
copyright years.
* module/ice-9/command-line.scm (version-etc): Bump 'copyright-year' to
2015.
* module/system/repl/common.scm (*version*): Add 2015 to the range of
copyright years.

helpers.
(scm_t_port): Ports now hold position as a pair, so that Scheme can
access it easily.

(SCM_DECCOL, SCM_TABCOL): Remove.
* libguile/ports.c (make_port_buffer): Rename from
scm_c_make_port_buffer, make static, and take port as an argument so
we can initialize the position field.

(scm_c_make_port_with_encoding): Initialize position.
(update_port_position): Rename from update_port_lf, and operate on
port position objects.

(scm_setvbuf, scm_expand_port_read_buffer_x): Adapt to
make_port_buffer change.
(scm_lfwrite): Adapt to call update_port_position.

(port_clear_stream_start_for_bom_read): Use
scm_specialize_port_encoding_x.
(scm_fill_input): Use scm_expand_port_read_buffer_x.
(scm_expand_port_read_buffer_x): Rename from
scm_set_port_read_buffer_x and actually expand the buffer.
* libguile/ports.h: Adapt to scm_expand_port_read_buffer_x change.
* module/ice-9/ports.scm: Remove ports-in-scheme stuff, and instead
expose the ports internals via an auxiliary module. This will let
ports-in-scheme live in a module during Guile 2.2.
