Breaking in Jabberwocky

> Hi Folks -
>
> I finally found the time to break in Jabberwocky by doing a sync of
> the Homebase repository with the Qwaq internal code base. All of these
> changes have been in use inside Qwaq for quite a while and improve
> various aspects of the system (detailed change log below). The changes
> shouldn't affect anything negatively (they are mostly conservative
> fixes) but if you find any problems, please let me know.
>
> To use those changes, you need to point Monticello at the Jabberwocky
> server:
>
>   http://jabberwocky.croquetproject.org:8889/Homebase
>
> and load the updated packages from there. Note that there is a
> load-order dependency which requires the System package to be loaded
> *before* the Morphic package, so make sure you get the changes in the
> right order or you'll run into problems. I have found that (starting
> with the 1.0 release) a good way to load these changes is to start
> with "System" and then load (or merge) everything else in alphabetical
> order.
>
> It might also be good if we could provide a preloaded Jabberwocky
> image for such purposes. Mark, any chance you could give this a shot?
>
> Special thanks to Bert Freudenberg, Goran Krampe, John McIntosh, Tim
> Rowledge and Scott Wallace who contributed to these fixes.
>
> And of course, all of this work was sponsored and brought to you by
> Qwaq, provider of secure collaboration spaces for enterprises.

> Enjoy,

> CHANGE LOG:
>
> Collections:
> ===========
> * ReadStream>>nextFloat is a new method for fast reading of floating
> point numbers (it outperforms Float>>readFrom: by a factor of ten)
> * SharedQueue>>includes: allows to safely test a shared queue for
> inclusion of objects
> * Transcripts now have their own text styles since TTFs can be very
> slow for heavy transcript usage
> * WeakCache provides a simple and easy way to weakly cache objects
> * A fix for PositionableStream>>nextWordsInto:
> * A fix for Stream>>printOn:
> * ifEmpty: and cousins now return self if not empty instead of nil
>
> CollectionTests:
> ===============
> * New tests for the expected behavior of ReadStream>>nextFloat
>
> Compiler:
> =========
> * Added Scott's workaround to avoid logging the entirety of a
> workspace when evaluating a doIt
> * We now accredit Undeclared variables in the same way we accredit
> shadowed variables, e.g., by listing Class>>method for the undeclared
> variable
>
> Exceptions:
> ==========
> * A new exception, OutOfMemory, has been added. It will be signaled
> when an allocation fails due to insufficient memory (like "Array new:
> SmallInteger maxVal")
> * AssertionFailure (a runtime condition) has been changed into a
> subclass of Error, not Halt so that it can be caught by the runtime
> machinery
>
> Files:
> ======
> * DosFileDirectoryTests have been fixed.
>
> Graphics:
> ========
> * We now have chromatically symmetric versions of #darker and
> #muchDarker which makes for perceptually more consistent gradients
> like in system windows
> * Bullet-proofing of strike fonts to make the font selection menu work
> again
> * Fix WarpBlt for 16->32bit conversions with smoothing enabled
>
> GraphicsTest:
> =============
> * Removed two failing tests which weren't obviously fixable.
>
> Kernel:
> =======
> * Signal OutOfMemory upon allocation failure to allow clients to
> handle this exceptional situation if they want to
> * Added a process token which allows explicit transfer of mutex
> ownership to other processes if needed
> * Included Tim's fix for extra-long delays which would otherwise lock
> up the image completely
> * Added a small safeguard for condenseChanges to avoid filing out the
> same methods multiple times
> * Added protection against setting the comment of a metaclass
> * Added fix for Process>>signalException: which would not work for
> subclasses of Process
> * Added a class comment for WeakMessageSend
>
> KernelTests:
> ============
> * Removed a number of non-working and fixed a number of broken tests
>
> Monticello:
> ==========
> * Make the repository inspector just a tad larger so that users can
> read most of the change log of a submission and not just the first line
> * Reverted some changes done last year since they broke the tests and
> the tests were obviously correct
> * Fixed or removed non-working tests
>
> MonticelloConfigurations:
> =========================
> * Disable MCC diffs by default but add a preference for re-enabling them
>
> Morphic:
> ========
> * SystemWindow improvements: Unobtrusive coloring, no pixellated
> outlines in buttons and better button alignment
> * Change the Morphic progress to be visually consistent with the Tweak
> progress bar
> * Make it possible for Morphs to deny the meta menu if they need to
> handle control clicks directly
> * Use a nice, happy green for progress
> * Use system control font for progress bar
>
> MorphicTests:
> =============
> * Fixed or removed non-working tests
> * Fixed TransformMorphTest not to leave remnants on the screen
>
> Multilingual:
> ============
> * Dodge an infinite recursion when a TTCFont has a fallbackFont whose
> baseFont is that same TTCFont
> * Fixed or removed non-working tests
>
> Network:
> =======
> * Update for SocketStream to use Goran's FastSocketStream for added
> speed and robustness
> * Fix HTTPUrl not to use a non-existent method to ask for password
> * Add a guard for an intermittent low-level I/O problem by having the
> (blocking) Socket>>waitForData: call wait in chunks of 500ms
>
> NetworkTests:
> =============
> * Removed non-working tests
>
> SMBase:
> ======
> * Fix an erroneous use of on: Exception do: which will cause all MC
> packages to fail to load from SM since they use notifications for
> progress indicators
> * Fixed or removed non-working tests
> * Removed SMDependencyTest since it required user interactions
>
> Sound:
> =====
> * Added a variety of missing methods to RepeatingSound
>
> ST80:
> =====
> * Fixed or removed non-working tests
> * Clipboard now uses preference #usePrimitiveClipboard to decide
> whether to use the OS clipboard, or just cut'n'paste within Squeak
>
> System:
> ======
> * Support for getting and setting the VM's window label
> * Fix condenseChanges to use the known classes and not blindly all
> behaviors (this can lead to filing out methods multiple times if
> obsolete classes exist)
> * Have condenseChanges imply a saveAs to preserve the previous image
> * Moved some methods from SmalltalkImage back to SystemDictionary
> (where they belong anyway)
> * Added Smalltalk>>verifySaneSources to make sure the sources are okay
> * speed up browsing by not showing the number of implementors of each
> method in the annotation panes - it takes an immense amount of time
> * Reduce duplicate code in SystemDictionary and SmalltalkImage by
> moving most methods from SmalltalkImage back to where they really belong
> * Added class comments for EventManager and MethodReference
> * Introduced standardControlFont for pushbuttons and labels in Tweak
> widgets.
> * Add 'usePrimitiveClipboard' preference so that we don't crash when
> using the clipboard on unix (we can't cut'n'paste between Squeak and
> other unix apps, but at least we don't crash).
> * Expose gcBiasToGrow and gcBiasToGrowLimit for tuning GC parameters
>
> Tests:
> ======
> * Removed some non-working tests; fixed one test
>
> ToolBuilder:
> ============
> * Removed non-working tests
>
> Tools:
> ======
> * Dramatically speed up PackagePaneBrowser by caching the currently
> selected package
> * Another major speedup for browsers by caching the message list
>
> VMMaker:
> ========
> * Added VM callback support
> * Added support for external GC roots
> * Added primitives for getting/setting the VM's window label
> * Added a triangle/box intersection primitive to CroquetPlugin
> * Fix or remove non-working tests
> * Added John McIntosh's QuickTime plugin (JMMMacQuicktimePlugin.3.cs).
> * Fix the typo in biasToGrow which John pointed out
>
