Fixed subprocess-wait, without blocking the toolkit.
* doc/gtk/gtk.texinfo, src/gtk/thread.scm, src/gtk/gtk.pkg: Rename
kill-gtk-thread to stop-gtk-thread, and export it to () for easy
emergency(!) use.
* src/gtk/: fix-demo.scm, gobject.scm, swat.scm: Use detach-thread.
* src/gtk/fix-layout.scm: Call gtk_widget_set_size_request; frobbing
GtkWidget requisition no longer (as of 2.22) works. Leave the widget
geometry undefined until the allocation callback can set it.
Added fix-ink-move! methods for image and box inks. These are very
simple methods, much like the method for text inks. Factored them
into a new generic-fix-ink-move! integrable.
* src/gtk/gtk.pkg: Import hook/subprocess-wait and nonblocking/
subprocess-wait, to enable non-blocking "synchronous" subprocesses.
* src/gtk/main.scm: Move startup out of initialize-package!, into
gtk-start, which is now used by make.scm. Thus startup is delayed
from load/compile(!)-time to load-option-time. Use exit- rather than
kill-gtk-thread. Fix type of argument to gtk_time_slice_window.
* src/gtk/make.scm: Use new gtk-start procedure.
* src/gtk/thread.scm: Added exit-gtk-thread and restart-gtk-thread.
* src/microcode/uxio.c (OS_test_select_registry): Fixed to return
SELECT_PROCESS_STATUS_CHANGE (or SELECT_INTERRUPT) instead of 0 when there
is no io (or the registry is empty) BUT pending status changes or
interrupts.
* src/runtime/process.scm (subprocess-wait): Replaced the call to the
process-wait primitive with application of hook/subprocess-wait.
Initialized this new binding to normal/subprocess-wait, which simply
calls the primitive. Implemented an alternative procedure,
nonblocking/subprocess-wait, which uses the new block-on-process-
status-change procedure. Added hook/subprocess-status-change.
* src/runtime/runtime.pkg: Import block-on-process-status-change from
(runtime thread) to (runtime process).
* src/runtime/thread-queue.scm: Added thread-queue/dequeue-no-hang and
thread-queue/dequeue-until, implementing the former in terms of the
latter. Like /peek-until, /dequeue-until does the job, which was
factored out into when-non-empty-before.
* src/runtime/thread.scm: Added block-on-process-status-change. Like
block-on-io-descriptor, it adds current-thread to those waiting on
descriptor 'process-status-change.

Now builds on x86_64 and via portable C distribution.
The build process now builds FFIs after it build-bands. An FFI's
"build" target now combines the old "generate" and "build" targets,
and knows from its host whether to compile-liarc-bundle. The
"install" target also knows whether to install-liarc-bundle.
Building the FFIs after build-bands means we can use src/microcode/
scheme and src/lib. Compiling the .scm after building the shim
ensures that the .scm's FFI syntax and the shim are consistent.
* doc/gtk/gtk.texinfo (Installation): Updated, with a section about
building the portable C distribution. Replaced "smallexample" with
"example" because of the former's smaller font.
* src/Makefile.in (build-ffis): This new target is needed in src/etc/
make-liarc.sh, and now appears after build-bands in most contexts.
Moved ffi from LIARC_BOOT_BUNDLES, and FFIS from LIARC_BUNDLES, but
not INSTALLED_SUBDIRS.
* src/configure.ac: Simplified the with-gtk default, which can expect
a host with an FFI after build-bands. Just test for Gtk 2.0 libraries
via pkg-config.
* src/etc/compile.scm (compile-ffi): Use in-liarc; delay C compilation.
* src/etc/make-liarc.sh: Add build-ffis after build-bands.
* src/gtk/Makefile-fragment: Combine generate and build into one, and
use ../microcode/scheme.
* src/gtk/gtk-shim.h: Replace "ulong" with "unsigned long".
* src/gtk/gtkio.c.stay: Make run_gtk's definition agree with its
declaration, and explicitly cast to select_registry_t.

Moved src/microcode/prgtkio.c to src/gtk/gtkio.c.
This simplifies the configuration of src/microcode/, removing
conditional references to the Gtks.
* doc/gtk/gtk.texinfo: Fixed the "make clean" suggestion to the proper
"make distclean". Simplified the build instructions, then made them
more novice-friendly, avoiding cautions about writable /usr/local/bin,
etc.
* src/configure.ac: Moved the --with-gtk support back from
microcode/achost.ac, where it is no longer needed.
* src/gtk/.gitignore: Added gtkio.c, a product of gtkio.c.stay.
* src/gtk/Clean.sh: Removed prgtkio.so; added gtkio.c.
* src/gtk/Makefile-fragment: Added gtkio.c, which is not compiled like
a regular shim. It uses the machine's OS interface, and narrowly
avoids including scheme.h.
* src/gtk/gtk-shim.h: Added extern declarations for functions that
used to be Gtk primitives.
* src/gtk/gtk.cdecl: Declare the new functions.
* src/gtk/gtk.sf: There is no prgtkio module, nor gtkio primitives
anymore.
* src/gtk/gtkio.c.stay: This is src/microcode/prgtkio.c with the
primitives turned into simple C functions.
* src/gtk/: main.scm, thread.scm: Replace Gtk primitives with callouts
to their equivalent C functions.
* src/microcode/: configure.ac, achost.ac: Punted --with-gtk.
* src/microcode/makegen/: Makefile.in.in, files-optional.scm: Punted
prgtkio.
* src/microcode/prgtkio.c: Moved to src/gtk/gtkio.c.stay.
* src/microcode/: pruxffi.c, pruxffi.h: Added abort_to_c(), so gtkio.c
does not need prim.h, scheme.h and everything.

Added SWAT emulation, just sufficient to run Pole Zero.
Changed scm-layout from an integer-based layout to a fixnum-based
layout called fix-layout. Added a "fix-" prefix to everything that
should be using fixnums. Thus there are many name changes:
scm-layout -> fix-layout
drawing -> fix-drawing
rect -> fix-rect
drawn-item -> fix-ink
I could not resist the brevity of "ink". "Item" is rather vague.
Changes not otherwise mentioned below:
Took care not to define-integrable when parameters are referenced
multiple times. Used integrate-operator instead.
Used guarantee-TYPE procedures rather than check-TYPE converters.
Punted :: for combining type and method names. A hyphen will do.
Used the new ignore declaration.
Punted package initialization declarations in gtk.pkg. Added
`(initialize-package!)' forms at the ends of files as necessary.
Followed the MAKE- convention to name procedures that create demos
or examples.
Signal callbacks now rely on their first parameter, the weakly
held instance, rather than capture it in their closures. The
first argument used to be the toolkit object's address.
* doc/gtk/gtk.texinfo: Incremented the minor VERSION. Moved many
implementation notes to a new Implementation Notes node. Condensed
the chapters about each example into subsections of the Introduction.
Added a subsection about the SWAT emulation. Added an Installation
chapter/node. Generally, re-wrote to the luser perspective. Used the
packaging in gtk.pkg, esp. the lists of names exported to (gtk), to
form a complete, if terse, API Reference. Pulled some luser
documentation out of the Scheme code.
* src/Makefile.in: Added ffi to the LIARC_BOOT_BUNDLES so that gtk can
be compiled during LiarC's bootstrap.
* src/README.txt: Moved gtk to the "miscellaneous extras".
* src/Setup.sh: Added sos to lib/.
* src/configure.ac: Made $with_gtk tri-valued: yes, no, auto. It
defaults to "auto". Moved pkg-config check to src/microcode/
achost.ac. Added gtk to FFIS.
* src/cref/: object.scm, redpkg.scm: Added support for declare forms
at top-level in .pkg files, and depends-on forms in package
descriptions. Added corresponding slots to the package, package-
description, and pmodel structures. A depends-on form lists files (by
default: .ext files) that should be generated before the package is
syntaxed. The top-level declare(s) are applied to all files.
* src/etc/compile.scm: Worked on LiarC support, moving the ffi to the
list of boot dirs. Added a compile-ffi procedure for the build target
of FFI Makefiles like src/gtk/Makefile-fragment.
* src/etc/functions.sh (maybe_rm): Do not skip symlinks.
src/config.sub and src/config.guess were not getting cleaned up. Add
them to FILES so they will be removed.
* src/gtk/: .gitignore, Clean.sh, Makefile-fragment: Added the
swat-pole-zero.scm symlink.
* src/gtk/Makefile-fragment: Use the compile-ffi procedure from
src/etc/compile.scm to compile the Gtk system. Use the host
MIT_SCHEME_EXE to generate the shim. Added a new liarc-build target
that compiles the gtk bundle.
* src/gtk/Includes/: Many useful declarations.
* src/gtk/demo.scm: Renamed "fix-demo.scm".
* src/gtk/ed-ffi.scm: Catch up changes to file packaging.
* src/gtk/fix-demo.scm: Was "demo.scm". Added a spinning arc-ink.
* src/gtk/fix-layout.scm: Was "scm-layout.scm". Many drawn-items were
re-implemented as draw-inks.
* src/gtk/gobject.scm: Added gobject-live?, gobject-unref!,
gdk-window-process-updates guarantee-gdk-window. Arrange for signal
callbacks to hold their instances weakly. Add-gc-cleanup now returns
the weak-pair it is using, so it can be reused by g-signal-connect.
Banish ferror; error will do.
* src/gtk/gtk-ev.scm: Init a ScmWidget's requisition member; it no
longer has a size-request method to do it. Use the new bit?
procedure to test bits in bit masks. Punted the second trace level.
Moved initialization out of make- procedure and into an
initialize-instance method.
* src/gtk/gtk-new.pkg: A temporary copy of gtk.pkg with the new
declare and depends-on expressions.
* src/gtk/gtk-object.scm: Added many new procedures and classes:
gtk-widget-realized?, gtk-widget-get-colormap, gtk-widget-show,
gtk-widget-connect-realize, gtk-bin-child, gtk-container-remove,
gtk-label-set-width-chars, <gtk-check-button>, <gtk-frame>,
gtk-window-set-opacity. Use the new bit? predicate.
Added a set-gtk-object-destroy-callback! procedure for the convenience
of gtk-object initialize-instance methods, for lack of "after" method
combination.
Take care when setting a style's font: copy the new
PangoFontDescription and free the old one.
Made gtk-widget-get-colormap and set-gtk-widget-bg-color! generic
procedures so that fix-layout can override them.
Noted that a gtk-container keeps its children in reverse order.
Centralized maintenance of the list. Operate on it atomically --
without-interrupts for now.
Moved gtk-object initialization from make- procedures to
initialize-instance methods for many widget types, so they can be
subclassed.
* src/gtk/gtk-shim.h: Punted the only method and all of the method
callback ids. The ScmWidget methods are now implemented by signal
callbacks.
* src/gtk/gtk.cdecl: Punted the widget method callbacks and added the
corresponding signal callbacks. Added several other new C function
and callback declarations. Moved some to a new
Includes/gtklabel.cdecl.
* src/gtk/gtk.pkg: Moved package (gtk pango) to earlier in the build.
Eliminated initialization declarations. Added new packages (gtk
swat), (swat) and (swat pole-zero), and many new bindings.
* src/gtk/gtk.scm: Gathered new syntax and fix: definitions for
system-wide use, expecting this file to be loaded at syntax as well as
load time. Added new bit-mask operators: bit-mask, bit-mask-indices,
and bit?. Moved the rect- procedures to fix-layout.scm. Replaced
check-!null with error-if-null. Punted ferror and fwarn. Moved Pango
hacks to pango.scm.
* src/gtk/gtk.sf: Use the new sf-package-set procedure, eliminating
60+ lines largely redundant to the info in gtk.pkg.
* src/gtk/hello.scm: Added an instance parameter to each callback.
* src/gtk/keys.scm: Use the new bit? predicate. Moved documentation
to gtk.texinfo.
* src/gtk/main.scm: Appended call to initialize-package!.
* src/gtk/make.scm: Incremented the Gtk subsystem's minor version number.
* src/gtk/pango-cairo.scm: Punted until real Cairo support is added.
* src/gtk/pango.scm: Added more argument checking, and a
pango-layout-set-font-description procedure. Collected other
Pango-related procedures, e.g. from gtk.scm. Moved luser
documentation to gtk.texinfo.
* src/gtk/scm-layout.scm: Renamed "fix-layout.scm".
* src/gtk/scm-widget.scm: Use g_object_ref_sink on a new ScmWidget.
Added set-scm-widget-set-scroll-adjustments-callback!. Punt method
callbacks. All methods are now implemented by signal callbacks.
* src/gtk/scmwidget.c.stay: Override the realize method, which assumes
the widget has no window. Add a set_scroll_adjustments signal.
* src/gtk/swat.scm: The new SWAT emulator.
* src/gtk/thread.scm: Just signal an error if there are no runnable
threads and no next-scheduled-timeout.
* src/microcode/achost.ac: Added the pkg-config check. Conditionally
add prgtkio.so to MODULE_TARGETS.
* src/microcode/configure.ac: Removed redundant pkg-config check --
redundant now that it is in achost.ac.
* src/microcode/prgtkio.c: The "uxselect.h" header no longer exists.
* src/runtime/ffi.scm: Added guarantee-alien-function and
error:not-alien-function. Fixed guarantee-alien to follow suit.
Added tracing to free-malloced-aliens.
* src/runtime/runtime.pkg: Added package (runtime thread-queue) and
guarantee-alien-function.
* src/runtime/thread-queue.scm: A queue that blocks threads.
* src/sf/: butils.scm, make.scm, sf.pkg: Added the sf-package-set
procedure, which uses CREF.

Added scm-layout event handlers and gdk-key support.
A more complete wrapping eliminates the need for c-includes in the
"Hello, World!" example and scm-layout demo.
* doc/gtk/gtk.texinfo: The FFI syntax is no longer used in hello.scm.
* src/gtk/Tags.sh: Fixed the exuberant ctags commandline to avoid
wiping out the Scheme file extensions list, thus punting *.scm.
* src/gtk/demo.scm: Use new callback and event wrappers.
* src/gtk/gtk-object.scm: Use integrate-operator where a parameter is
referenced multiple times.
(gtk-widget-font): Return a PangoFontDescription alien.
(set-gtk-button-clicked-callback!)
(set-gtk-window-delete-event-callback!): More wrapping, to get
C-callback syntax out of hello.scm and demo.scm.

* src/gtk/gtk-ev.scm: Punt impish delete_event callback from hello.
* src/gtk/hello.scm: Simplify. Use new wrappers.
* src/gtk/keys.scm: New.
* src/gtk/scm-layout.scm: Punted null-alien in favor of 0. Added an
"event-handlers" vector per widget. Provide specific event handler
setters, which can translate from toolkit to Scheme constants, so the
provided handlers do not need C- syntax.
(scm-layout-event-handler): Handle expose events directly. Lookup the
rest in the event-handlers vector.

For Edwin: gtk-widget-font, scm-layout-scroll-step, etc.
* doc/gtk/gtk.texinfo: Followed the example of ffi.texinfo. Added
VERSION. Changed name from "Users'" to "Reference" Manual. Clarified
how to run the examples.
* src/Makefile.in: Use @FFIS@ to init FFIS, allowing gtk to be built
conditionally. Install lib/conses.png only when the Gtk interface is
built.
* src/Setup.sh: The lib/lib/prgtkio.so symlink is no longer needed.
* src/configure.ac: Added support for a --with-gtk option, to
conditionally include Gtk. Added --enable-debugging, needed in
microcode/achost.ac.
* src/gtk/.gitignore: Make git ignore the gtk-shim build byproducts.
* src/gtk/Includes/, src/gtk/gtk.cdecl: Added and deleted various
declarations.
* src/gtk/demo.scm: Renamed the event handler "demo-event-handler".
Added a call to gtk-widget-grab-focus.
* src/gtk/ed-ffi.scm: Added pango.scm.
* src/gtk/gobject.scm: Added punt-gc-cleanup, for alien objects that
can be explicitly destroyed as well as GCed. Allow for C-enum values
that do not fit in a fixnum. Treat them as integers.
* src/gtk/gtk-object.scm: Defined and used gtk-object-flags, despite
their being deprecated. Added peek-gtk-adjustment, for debugging.
Added gtk-widget-queue-draw, -get-pango-context, -create-pango-layout,
-set-size-request.
Added gtk-widget-font, -bg-color, -fg-color, -base-color, and
-text-color, and their setters, mostly from scm-layout.scm.
Added gtk-scrolled-window-set-policy and -set-placement.
Replace guarantee-gtk-window with check-gtk-window. Use
error:wrong-type-argument in the check-TYPE procedures.
Fixed the C types peeked by gtk-window-get-default-size.
* src/gtk/gtk.pkg: Added several new exports, and a new (gtk pango)
package. Moved color and font support from (gtk layout) to (gtk
gtk-object).
* src/gtk/gtk.scm: Added rect-union!. Use integer operators on pixel
coordinates and sizes. Moved most of the Pango code to the new
pango.scm file.
* src/gtk/gtk.sf: Suppress option loading noise. Syntax each file in
its respective package, as its dependencies require.
* src/gtk/hello.scm: Quiet warnings. Punt call to error; keeping it
simple. This code appears in the manual.
* src/gtk/main.scm: Punt private copy of ucode-primitive syntax
transformer.
* src/gtk/pango.scm: New, implementing <pango-layout> as a <gobject>.
* src/gtk/scm-layout.scm: Created a second, "detailed" trace level.
Allow logical device coordinates and sizes to be integers, not just
fixnums. Added set-scm-layout-scroll-step! and scm-layout-realized?.
Init on-screen-area to an un(der)defined rect. Adjust scrollbars only
when realized and necessary.
Moved the color support to gtk-object.scm. None of it depends on
scm-layout anymore -- just gtk-widget. Re-worked the
_get_modifier_style,modify,_modify_style abstraction to accommodate
set-rcstyle-font!.
Combined common scrolling code from set-scm-layout-scroll-pos!,
scm-layout-adjustment-value-changed.
Allow drawing-add-item! to splice in an item just under/before
another, given item.
Keep drawn-item changes (damage old area, move, damage new area)
thread-atomic, else another thread can interfere.
* src/gtk/thread.scm (kill-gtk-thread): Send ONE thread event, and
clear gtk-thread first.
* src/microcode/configure.ac: Put prgtkio.so on MODULE_TARGETS, not
_BASES. The latter does too much.

providing them immediately to latecomers. (The update hook, on the
other hand, might never call.) The close hook is run in the loader's
thread (or the latecomer's) after gdk_pixbuf_loader_close has been
closed, and any error status collected.
* src/gtk/: gobject.scm, gtk-object.scm, scm-layout.scm:
Use "cleanup" instead of "finalize" to avoid confusion with Gtk's
notion of finalization. Assume gc-cleanups are without-interrupts.
Do NOT run gc-cleanups in a gc-daemon; run them in gtk-thread. Added
more tracing; named more lambdas.
* src/gtk/gtk.pkg:
Declare new pixbuf-loader interface. Rename (gtk object) package

floating-point exceptions for which trapping is enabled; but, on the

Added trivial tests for conversion to floating-point infinities by
`cast-integer-to-ieee754-single' and `cast-integer-to-ieee754-double'.

* Renamed `cast-flonum-to-integer' to `cast-ieee754-double-to-integer'.
* Renamed `cast-integer-to-flonum' to `cast-integer-to-ieee754-double'.
* Changed both to use <uint64_t> instead of <unsigned long> for
conversion. That way, they should work on 32-bit systems. (Thanks to
Taylor for pointing out that bug.)
* Added `cast-ieee754-single-to-integer' and `cast-integer-to-ieee754-single'.
* Updated existing tests.
* Added tests for casts to and from single-precision floating-point numbers.

Removed the divisions by zero that I had used to create floating-point
infinities since those are supposed to trap, not actually return
infinities. On OS X, the trap doesn't happen, but I shouldn't depend
on a bug.
