this happens when removing Collection's #inspect method, during Blox's
load). Thanks to Christopher Painter-Wakefield for signaling this.

as part of the changes below for Delay.
* kernel/Delay.st: Added backgroundProcess in Delay's
#startDelayLoop class method, and added #idle class method.
Fixed so that delays across two evaluations (i.e. an evalua-
tion starts, a delay is pending when it ends, and then another
evaluation starts which must discard that delay and accept
new ones) works.
* examples/Dinner.st: Ditto

1999-02-26 Paolo Bonzini <bonzini@gnu.org>

* kernel/Class.st: #removeClassVarName: referred to non-
existent method #classVariables (instead of #classPool)

1999-02-23 Paolo Bonzini <bonzini@gnu.org>

* kernel/Symbol.st: Changed storeOn: to properly handle #'ab cd'
symbols and printOn: to use the version inherited from String

1999-02-22 Paolo Bonzini <bonzini@gnu.org>

* kernel/Bag.st: printOn: sent `print: ($ )' instead of `space'
* examples/Dinner.st: Created.
* kernel/Process.st: Added various accessors for the regression
tests, changed many things because of changes in the VM,
new experimental interrupt mechanism.
* kernel/ProcSched.st: Added various accessors to account for the
changes in Process.
* kernel/Builtins.st: Moved #blockCopy:... to ContextPart

1999-02-19 Paolo Bonzini <bonzini@gnu.org>

* examples/Queens.st: Created.

1999-02-17 Paolo Bonzini <bonzini@gnu.org>

* kernel/SysDict.st: Added class accessors (eg allBehaviorsDo:)

1999-02-16 Paolo Bonzini <bonzini@gnu.org>

* kernel/CompildMeth.st: Changed for new representation of
literals

1999-02-15 Paolo Bonzini <bonzini@gnu.org>

* kernel/PosStream.st: Fixed #reset to use #position:
* kernel/FileStream.st: Added selectors for new style opening
modes (FileStream open: 'foo' mode: FileStream read)

1999-02-14 Paolo Bonzini <bonzini@gnu.org>

* kernel/ContextPart.st: Finally got the unwinding system to
work.

1999-02-13 Paolo Bonzini <bonzini@gnu.org>

* kernel/Symbol.st: Added isSymbolString:
* kernel/CType.st: Great! Factored out everything in CScalarCType!
C*Type are now instances of CScalarCType. So we save a source of
confusion (is it CByteCType or CByteType?!?) and ten classes which
were carbon copies.

1999-02-12 Paolo Bonzini <bonzini@gnu.org>

* examples/Publish.st: Added HTML output

1999-02-09 Paolo Bonzini <bonzini@gnu.org>

* examples/Tokenizer.st: Removed recording, which was way too
slow and in fact not even needed by the compiler.
* kernel/Behavior.st: Fixed bug in #extractEvalChunk: not
handling unterminated string literals.
* kernel/Collection.st: Added #removeAll:ifAbsent:

1999-02-08 Paolo Bonzini <bonzini@gnu.org>

* kernel/ExcHandling.st: fixed bug with unwind mechanism: in
code like [ [ 1/0 ] valueWithUnwind ] on: ExAll do: [ :sig | ... ]
the exception handler must NOT be used - in other words, if we
are inside a #valueWithUnwind, outer exception handlers are
momentarily disabled.
* kernel/PkgLoader.st: Created.
* Load.st: Created.
* Reload.st: Created.

1999-02-05 Paolo Bonzini <bonzini@gnu.org>

* kernel/ExcHandling.st: Added ExUserBreak.
* kernel/LinkedList.st: Fixed missing dot problem - probably I
had introduced it earlier.

1999-02-04 Paolo Bonzini <bonzini@gnu.org>

* kernel/ContextPart.st: Fixed bug in the unwinding system
(using SystemDictionary>>#halt did not work properly)

1999-02-01 Paolo Bonzini <bonzini@gnu.org>

* kernel/Builtins.st: 'self perform: <a Message>' now acts
like '<a Message> sendTo: self' - stole from Dolphin Smalltalk:
not particularly useful, but makes GST more `universal'
* kernel/Symbol.st: Added with:...
* kernel/ObjDumper.st: Changed superclass to Stream. Added proxy
feature.
* kernel/IdentDict.st: Created a separate version of growBy:
which does not involve Associations (which are not used by
IdentityDictionaries). This halved the execution time for
Andreas Klimas' little torture test (examples/mixed/torture.st),
performing half the GCs.
* kernel/FileStream.st: Fixed open and popen to use basicNew
instead of new. new is now disabled.

1999-01-31 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Switched FileStream to returning nil on
failure only if errno = 0. If not, it is probably better to check
the errno. Things like search paths, etc, can be still implemented
(from the highest level to the lowest)
a) by using methods like open:mode:ifFail:
b) by using new exception handling mechanisms
c) by using methods like fileOp:ifFail: - see open:mode:ifFail:

1999-01-29 Paolo Bonzini <bonzini@gnu.org>

* kernel/CObject.st: Added CBoolean.
* kernel/CType.st: Added CBooleanCType
* kernel/Boolean.st: Added `self subclassResponsibility' methods
* kernel/True.st: Added asCBooleanValue
* kernel/Browser.st: Changed the BrowserClassesValid global
(brrr!!!!) to a more sedate-sounding class variable.

1999-01-28 Paolo Bonzini <bonzini@gnu.org>

* kernel/FileStream.st: #close now sets the `file' instance variable
to nil, to prevent multiple closes of the same file. At least under
Win32 this does not usually cause SIGSEGV or similar: however you
might end up closing the file descriptor for some other open file,
resulting in difficult to catch bugs
* kernel/Behavior.st: Added a few goodies needed to make lightweight
classes work a little better (#new class method, #name instance method)
* kernel/LargeInt.st: Added ~=

1999-01-27 Paolo Bonzini <bonzini@gnu.org>

* kernel/Date.st: Changed now that assignment to argument is invalid.
Fixed asSeconds to answer seconds from 1/1/1901 - with LargeIntegers,
there's no reason to answer seconds from 1/1/1970.

1999-01-26 Paolo Bonzini <bonzini@gnu.org>

* kernel/File.st: Changed now that assignment to argument is invalid
* kernel/CompildMeth.st: Also
* kernel/Integer.st: Also
* kernel/ObjDumper.st: Also

* kernel/Point.st: Also
* kernel/Rectangle.st: Also
* kernel/SeqCollect.st: Also
* kernel/Set.st: Also
* kernel/String.st: Also
* kernel/LargeInt.st: Also
* kernel/Collection.st: Changed now that assignment to argument is
invalid. Switched to quicksort for implementing #asSortedCollection:.
* kernel/SortCollect.st: Changed now that assignment to argument is
invalid. Switched to quicksort for implementing #asSortedCollection:.

1999-01-18 Paolo Bonzini <bonzini@gnu.org>

* kernel/Float.st: Fixed up floating point printing to round
correctly. It should work now...
* kernel/LargeInt.st: Implemented a faster way to print
LargeIntegers: I split them into small parts which stay into a
small integer: this usually results in executing a lot fewer
bytecodes (650,000 instead of 5,500,000 to print 1e36)!!
* kernel/Integer.st: Added special floorLog: implementation. Added
largest/smallest.

1999-01-16 Paolo Bonzini <bonzini@gnu.org>

* examples/Tokenizer.st: Added line counting
* kernel/ByteStream.st: Created.
* kernel/ByteArray.st: Added Memory-style accessors. Very
interesting!!

1999-01-15 Paolo Bonzini <bonzini@gnu.org>

* kernel/WriteStream.st: Removed maxSize instance variable

1999-01-13 Paolo Bonzini <bonzini@gnu.org>

* kernel/CFuncs.st: Added getArgc and getArgv

1998-12-15 Paolo Bonzini <bonzini@gnu.org>

* examples/Publish.st: Added class hierarchy (previously methods
laid in ClassDescription).

1998-12-10 Paolo Bonzini <bonzini@gnu.org>

* kernel/ObjDumper.st: Added support for byte objects with fixed
instance variables.

1998-12-09 Paolo Bonzini <bonzini@gnu.org>

1998-11-29 Paolo Bonzini <bonzini@gnu.org>

* kernel/Metaclass.st: Finished integration of class-instance
variables

1998-11-27 Paolo Bonzini <bonzini@gnu.org>

* kernel/Character.st: Added lookup table for speed

1998-11-25 Paolo Bonzini <bonzini@gnu.org>

* kernel/Rectangle.st: Changed #intersect to make it work ;-)
* kernel/Builtins.st: Added String>>hash and ByteArray>>hash

1998-11-24 Paolo Bonzini <bonzini@gnu.org>

* kernel/ExcHandling.st: Now uses ContextPart class>>#unwind
mechanism
* examples/PushBack.st: Added #position and #position:
* kernel/Metaclass.st: Added methods for class pool/shared pools,
which delegate their work to Class

1998-11-23 Paolo Bonzini <bonzini@gnu.org>

* kernel/BlkContext.st: Switched superclass to ContextPart.
* kernel/MthContext.st: Switched superclass to ContextPart.
* kernel/ContextPart.st: Created.

1998-11-18 Paolo Bonzini <bonzini@gnu.org>

* examples/Debugger.st: Added experimental bytecode simulator.

1998-11-14 Paolo Bonzini <bonzini@gnu.org>

* kernel/CStruct.st: Changed to subclass of CObject and changed
implementation of inspection for easier port to Blox.

1998-11-10 Paolo Bonzini <bonzini@gnu.org>

* kernel/UndefObject.st: Added class creation methods.
* kernel/Object.st: Added class declaration now that nil defines
class creation statements
* kernel/Autoload.st: Class directly created as subclass of nil.

1998-11-05 Paolo Bonzini <bonzini@gnu.org>

* kernel/Metaclass.st: Added instanceVariableNames: for class-instance
variables. Modified mutation policy to be a bit more restrictive but
logical.

1998-10-21 Paolo Bonzini <bonzini@gnu.org>

* examples/CompFileSeg.st: Created.

1998-10-15 Paolo Bonzini <bonzini@gnu.org>

* kernel/CObject.st: Added CSmalltalk. Turned to a variable word
subclass to make access to the address simpler and not cause SIGSEGVs
on trying to access the address instance variable as an object
* kernel/CType.st: Added various storeOn: methods, and classes
CScalarCType and CSmalltalkCType

1998-10-13 Paolo Bonzini <bonzini@gnu.org>

* kernel/Float.st: Changed to a variable byte subclass.
* kernel/Number.st: Added #zero and #unity

1998-10-12 Paolo Bonzini <bonzini@gnu.org>

* kernel/BlkClosure.st: Created from BlkContext.st.
* kernel/SeqCollect.st: Switched to copyEmpty: about a week ago.
Now tried to change to:do: to whileTrue: in a desperate attempt
at gaining more speed ;-)
* kernel/BlkContext.st: Changed to support blocks as closures

1998-10-11 Paolo Bonzini <bonzini@gnu.org>

* kernel/Collection.st: Added copyEmpty:, copyEmpty now uses it.
* kernel/Dictionary.st: Changed growing mechanism and other methods
to use #copyEmpty: Also, now #keyAtValue:ifAbsent: uses identity
to compare objects. This was marked as a 'questionable' change in
Brad Diller's extras.st file, but it turns out that most Smalltalks
implement this method this way.
* kernel/OrderColl.st: Switched to using copyEmpty: when growing.
* kernel/Set.st: Switched to using copyEmpty: when growing.

1998-10-10 Paolo Bonzini <bonzini@gnu.org>

* kernel/LargeInt.st: Removed 'self sign = 0' tests, replaced
with overridden methods in LargeZeroInteger.

1998-10-08 Paolo Bonzini <bonzini@gnu.org>

* kernel/ArrayColl.st: Moved here the growing methods that used to
be in SequenceableCollection. Why weren't they
here? OrderedCollection has a different growing
system...

1998-10-04 Paolo Bonzini <bonzini@gnu.org>

* kernel/Behavior.st: Fixed symbol that was being printed instead of
nextPutAll:'d in definition of C functions.

1998-09-30 Paolo Bonzini <bonzini@gnu.org>

* kernel/Rectangle.st: Made #origin, #corner, #bottomRight and
#topLeft return copies of the origin and corner. This is for
consistency with #bottomLeft, #topCenter, etc.
* kernel/TokenStream.st: Removed a few methods whose implementation
was the same as Stream's.

1998-09-29 Paolo Bonzini <bonzini@gnu.org>

* kernel/Object.st: Switched dependancy mechanism to use IdentitySets.
Also declared Dependencies as part of Smalltalk.

1998-09-28 Paolo Bonzini <bonzini@gnu.org>

* kernel/Set.st: Changed storeOn: to avoid hard coding Set as the
class name.
* kernel/CStruct.st: Changed to a fixed subclass. Added 'put'
methods.
* kernel/IdentitySet.st: Created.
* kernel/Directory.st: Promoted to kernel from cxtnsn.
* kernel/File.st: Promoted to kernel from cxtnsn.

1998-09-25 Paolo Bonzini <bonzini@gnu.org>

* kernel/ValueAdapt.st: Created.

1998-09-18 Paolo Bonzini <bonzini@gnu.org>

* kernel/Time.st: Fixed possible secondClock overflow.
Added #asSeconds
* kernel/Date.st: Fixed possible secondClock overflow. Now it
will overflow somewhen in 2038. Hope 64-bit machines are
widespread enough by that time... I'll be 58.

1998-09-15 Paolo Bonzini <bonzini@gnu.org>

* kernel/Builtins.st: Added CObject>>free, String>>valueAt:,
String>>valueAt:put:
* kernel/Random.st: Changed algorithm. Needed because, with new
LargeInteger support, the old algorithm created a lot of temporary
objects and caused a lot of GCs. This algorithm uses Floats; it
has approximately the same chisquare as the old one. The performance
is not as good as when it used small Integers, but better than
LargeIntegers. There are algorithms which use small Integers without
overflowing; I know about one of them, but it only works with 32 bit
words and ours only have 30 bits. Tell me if you can find one!

1998-09-14 Paolo Bonzini <bonzini@gnu.org>

* kernel/BlkContext.st: Added accessr functions; there didn't seem to be a
good reason why they weren't there in the first place.
* kernel/MthContext.st: Oops... methodClass instance variable was missing!
* kernel/BlkContext.st: Added printOn: and backtrace methods
* kernel/PosStream.st: Modified so that upTo:, upToAll:, skipTo:, upToEnd,
skipToAll: operate unidirectionally on the receiver. This is needed to
make them work with special streams such as stdin.
* kernel/MthContext.st: Added printOn:, home and backtrace methods

1998-09-10 Paolo Bonzini <bonzini@gnu.org>

* kernel/Builtins.st: Added support for LargeIntegers. This
included adding a 'fail' section to Integer>>asFloat. Also changed
asObjectNoFail to return nil if bad OOP index.
* kernel/WordMemory.st: Added LargeInteger support (well, actually
just removed 'sorry, no LargeIntegers yet' errors); shifted to
to bitShift: instead of * and // (which are slow with LargeIntegers).
Also now #at:put: returns the stored value (which is what it was
always supposed to do, like any other #at:put:). Finally, the size
of a word is now CLongSize instead of always 4 bytes.
* kernel/Time.st: Fixed secondClock to use LargeIntegers.

1998-09-09 Paolo Bonzini <bonzini@gnu.org>

* kernel/initialize.st: Modified to initialize LargeInteger.

1998-09-08 Paolo Bonzini <bonzini@gnu.org>

* kernel/Builtins.st: Added Behavior>>#flushCache.
* examples/Tokenizer.st: Created from Tok
* examples/PushBack.st: Removed recording capability, which was too
expensive in terms of performance, and moved it to Tokenizer.
* kernel/LargeInt.st: Created.

1998-09-07 Paolo Bonzini <bonzini@gnu.org>

* kernel/WriteStream.st: Changed the growing policy so that
WriteStreams are more efficient at concatenating data.

1998-09-06 Paolo Bonzini <bonzini@gnu.org>

* kernel/MethodInfo.st: Added setSourceCode: to support compiler.

1998-09-03 Paolo Bonzini <bonzini@gnu.org>

* kernel/Set.st: Merged changes by Brad Diller to solve rehash bug.
Added primAt:/primAt:put: to support subclasses that for example
store data on disk or on a separate instance variable.
* kernel/Float.st: Added #asFraction using a continued fractions
algorithm (ugh!)
* kernel/Date.st: Extended to make it more flexible.
* kernel/Interval.st: Fixed bug in #size, returning negative sizes
if step < 0. Changed superclass to ArrayedCollection.
* kernel/Fraction.st: Integrated changes.st.
* kernel/Behavior.st: Merged changes by Brad Diller.
* kernel/Builtins.st: Merged changes by Brad Diller.
* kernel/ClassDesc.st: Merged changes by Brad Diller.
* kernel/Metaclass.st: Merged changes by Brad Diller.
* kernel/Object.st: Merged changes by Brad Diller.
* kernel/IdentDict.st: Merged changes by Brad Diller to solve rehash
bug.
* kernel/Dictionary.st: Merged changes by Brad Diller to solve rehash
bug. Also modified add: to resuse the existing Association if there
is one, rather than always using the parameter. Changed hashing so
that hashing a dictionary that contains itself is not a problem.
* kernel/Class.st: Merged corrections by Brad Diller.
* kernel/Association.st: Switched superclass to be Magnitude. Added
class equality test to Association>>#=

* kernel/DirMessage.st: Created.
* kernel/RunArray.st: Created around January 1997.
* kernel/ObjDumper.st: Created around March 1997.
* kernel/ExcHandling.st: Now uses SystemDictionary>>#halt. Thanks
Brad Diller.

1998-09-02 Paolo Bonzini <bonzini@gnu.org>

*** Began development of version 1.6

1997-07-23 Paolo Bonzini <bonzini@gnu.org>

* kernel/ExcHandling.st: Created.

1996-04-15 Paolo Bonzini <bonzini@gnu.org>

* kernel/Set.st: Refactored to reduce duplicated code
in Dictionary and IdentityDictionary.

1995-09-30 Steve Byrne <sbb@gnu.org>

*** Version 1.1.5 released.

1995-09-16 Steve Byrne <sbb@gnu.org>

* kernel/CType.st: Removed separate valueType defintion for
pointers and arrays (returning eltCType); using the inherited
version instead.
* kernel/Fraction.st: Added storeOn:, cleaned up formatting a bit.
* kernel/Class.st: Fixed a bug in subClass:... was saying 'words: true',
which means that the object consists of non-gc'ed words. subClass is
pointers which are GC'ed, and saying word: true was just plain 100%
wrong.

1995-09-09 Steve Byrne <sbb@gnu.org>

* kernel/CType.st: Adjusted sizes of scalar types to use actual
values for the platform instead of constant values that Smalltalk
made up.

1995-09-04 Steve Byrne <sbb@gnu.org>

* kernel/Class.st: Incorporated (finally) Jim Fulton's fix to the =
operator.
* kernel/Object.st: Incorporated (finally) Jim Fulton's fixes to
removeDependent:

1995-08-26 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Modified Behavior #new & friends (primitives
70 & 71) to issue errors when they are used inappropriately
(such as sending #new to an indexable class).

1995-07-23 Steve Byrne <sbb@gnu.org>

* kernel/CStruct.st: Added struct datatypes int and uInt.

1995-07-16 Steve Byrne <sbb@gnu.org>

* kernel/Behavior.st: Fixed instsize to correctly shift by 4, now
that bit 0 (st) is reserved for the hasFinalize flag.

1995-07-14 Steve Byrne <sbb@gnu.org>

* kernel/Metaclass.st: Fixed so that invalid variable names cannot
be declared.

1995-05-29 Steve Byrne <sbb@gnu.org>

* kernel/Boolean.st: Fixed to have a simple deep copy and shallow
copy.

1995-05-07 Steve Byrne <sbb@gnu.org>

* kernel/CObject.st: Added usage of more machine size constants
(float,long, ptr, double).

1995-05-06 Steve Byrne <sbb@gnu.org>

* kernel/CStruct.st: Updated for new C type system.

1995-05-01 Steve Byrne <sbb@gnu.org>

* kernel/CType.st: Changed CType>>cObjectType to return CObject
instead of subclass responsibility.

1995-04-29 Steve Byrne <sbb@gnu.org>

* kernel/CType.st: Added cObjectType -- may be replacing
what the baseType method was, but this is more
descriptive. Also added a new operation on CType
instances to create a new CObject subclass from the
CType instance.
* kernel/CObject.st: Moved the creation of CType instances into
CType. Removed forward declaring of CType instances from this
file and changed the load order to load CObject first
since it now has no dependencies on the CType symbols.
* kernel/CType.st: Moved the creation of the instances of CType
subclasses into this file -- makes more sense here.
* kernel/CType.st: Removed baseType -- it appears to have no function
now.

1995-01-08 Steve Byrne <sbb@gnu.org>

* kernel/CObject.st: Converted to new types.
* kernel/CObject.st: Fixed some bugs with pointer subtraction.

1995-01-02 Steve Byrne <sbb@gnu.org>

* kernel/CType.st: Hacked for new type architecture.

1994-10-08 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added SystemDictionary>>growTo:

1994-09-15 Steve Byrne <sbb@gnu.org>

*** Version 1.2.alpha1 released.

1994-08-30 Steve Byrne <sbb@gnu.org>

* examples/MemUsage.st: Added header stuff
* examples/PrtHier.st: Added header stuff.

1994-08-21 Steve Byrne <sbb@gnu.org>

* kernel/Behavior.st: Adjusted tests for low bit int marking.
* kernel/CompildMeth.st: Fixed for low bit int marking

1994-08-14 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Fixed ~~ on integers to return true (the
objects did not match) if the primitve failed.

1994-07-24 Steve Byrne <sbb@gnu.org>

* kernel/FileStream.st: Added class>>require:

1994-07-10 Steve Byrne <sbb@gnu.org>

* kernel/ClassDesc.st: Fixed instVarNames to deal properly with
classes which have no instance variables.
* kernel/MthContext.st: Added accessr functions; there didn't seem
to be a good reason why they weren't there in the first place.
* kernel/Class.st: Fixed allClassVarNames and allSharedPools to
properly deal with nil collections of class variables or
pool dictionaries.

1994-07-02 Steve Byrne <sbb@gnu.org>

* kernel/SysDict.st: Fixed dependenciesAt: to return nil if there
was no dependency already present.

1994-06-12 Steve Byrne <sbb@gnu.org>

* kernel/CObject.st: Added adjPtrBy:, derefAt:, etc. (finally).

1994-04-30 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added incrBy:

1994-04-09 Steve Byrne <sbb@gnu.org>

* kernel/CObject.st: Added CScalar, value: methods on scalar
instances as a shorthand notation for instance creation, started
folding in the effects of the CType new method.
* kernel/CType.st: Added alloc:type:

1994-04-05 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added CObject>>alloc:type:

1994-03-26 Steve Byrne <sbb@gnu.org>

* kernel/WordMemory.st: Added little endian support.

1994-02-06 Steve Byrne <sbb@gnu.org>

* kernel/ProcSched.st: Fixed the 'symbolic constants' for priority to
actually return their values, instead of returning
self (duh!).

1993-10-17 Steve Byrne <sbb@gnu.org>

* kernel/Message.st: Added accessors for the components.

1993-10-16 Steve Byrne <sbb@gnu.org>

* kernel/ProcSched.st: Fixed yield to operate correctly in the
presence of repeated higher priority interrupts.
* kernel/ClassDesc.st: Fixed addInstVarName: specially treat meta
classes and grow their single class instances when new instance
variables are added to the class.

1993-10-03 Steve Byrne <sbb@gnu.org>

* kernel/ArrayColl.st: Put in #copy, to use replace from to get the
nice efficient copy that we can have if we are an array.

1993-10-01 Steve Byrne <sbb@gnu.org>

* kernel/Dictionary.st: Fixed removeKey:ifAbsent: to evaluate the
ifAbsent block if the key actually was absent. Previously,
this was being evaludated only if the entire dictionary was full
and the key was not found.

1993-09-26 Steve Byrne <sbb@gnu.org>

* kernel/Collection.st: Made exceptionBlock's value in
detect:ifNone: be returned, so the exception handler could just
yield a value if it wanted.
* kernel/String.st: Fixed some methods to check its second
operand's type before calling into primitives which don't check type.

1992-11-27 Steve Byrne <sbb@gnu.org>

* kernel/Class.st: Fixed variableSubclass:... to correctly mark new
subclasses as being pointers and indexable, but not words (words
implies unscanned raw data).
* cxtnsn/DLD.st: Added support to DLD for searching through a list of
libraries to resolve references, with the default being libc.

1992-05-25 Steve Byrne <sbb@gnu.org>

* kernel/Browser.st: Added support for Emacs caching class names

1992-02-23 Steve Byrne <sbb@gnu.org>

* kernel/String.st: Added asInteger and asByteArray.

1992-02-16 Steve Byrne <sbb@gnu.org>

* kernel/Autoload.st: Created in the 1.1 timeframe
* kernel/Fraction.st: Created in the 1.1 timeframe
* examples/Publish.st: Created 02 92.
* kernel/Browser.st: Created a while ago
* kernel/CType.st: Created summer 90
* kernel/CObject.st: Created summer 90.
* kernel/CStruct.st: Created summer 90.

1992-02-15 Steve Byrne <sbb@gnu.org>

* kernel/Collection.st: Switched the collection creating enumerators
to use the copyEmpty message, so it can be overridden by subclasses
(like SortedCollection) when copying empty involves more than
just doing a new.

1991-12-14 Steve Byrne <sbb@gnu.org>

* kernel/ByteArray.st: Added asString -- generally useful functionality,
but especially for STIX.

1991-11-28 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added SystemDictionary byteCodeCounter.
* kernel/ByteArray.st: Added growSize method -- 10 wasn't right, and
we should probably base the grow size on the size of the object in
question.
* kernel/ByteArray.st: Switched shallowCopy to use faster primitives.

1991-11-02 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Fixed == and ~~ definitions for Integer to fail
if the integers aren't = (including the case where they aren't both
integers). Used to retry:coercing: which lost badly.

1991-10-20 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added support for user level control of GC growth
rate flags.

1991-09-22 Steve Byrne <sbb@gnu.org>

* kernel/FileStream.st: Added #popen:dir:ifFail: and #open:mode:ifFail:
so that open failures can be explicitly handled.
Thanks to Michael Richardson for the brilliant idea!
* kernel/Builtins.st: Switched FileStream to returning nil on failure,
so that higher level methods can chose to deal with failure. This was
due to a brilliant observation by Michael Richardson. Now that higher
level functions can handle failure, things like search paths, etc,
can be trivially implemented.

1991-09-15 Steve Byrne <sbb@gnu.org>

* kernel/CompildMeth.st: Adjusted to account for larger numbers of
primitives, literals, and temporaries.

1991-07-28 Steve Byrne <sbb@gnu.org>

* kernel/Rectangle.st: Added #= and #hash methods.
* kernel/Point.st: Added = for Points (= from Object isn't right)
* kernel/Stream.st: Added store: for streams (can't imagine why it
wasn't here before).
* kernel/Rectangle.st: Altered the printing and storing to use
cascaded messages.

1991-07-05 Steve Byrne <sbb@gnu.org>

* kernel/FileStream.st: Added fileIn:line:from:at: so that when
Emacs sends out an expression or a method definition to Smalltalk
the error messages accurately report the line number.
* kernel/Builtins.st: Added fileInLine:fileName:at: to improve error
reporting and recording of file position information for later
browsing.

1991-06-26 Steve Byrne <sbb@gnu.org>

* kernel/False.st: Fixed ifFalse: to send value to falseBlock

1991-06-06 Steve Byrne <sbb@gnu.org>

being direct primitives to a more general primitive mechanism.

1991-05-18 Steve Byrne <sbb@gnu.org>

account of the number of digits printed in the integer part
when printing the fractional part.

1991-03-23 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added Integer primitives == and ~~ for more
efficient operation.

1991-02-16 Steve Byrne <sbb@gnu.org>

* kernel/Dictionary.st: Override the #new method from builtins when

#new method instead of the built-in one that only creates Dictionary instances.

1991-02-07 Steve Byrne <sbb@gnu.org>

1990-09-22 Steve Byrne <sbb@gnu.org>

* kernel/False.st: Changed printOn: to reflect changes in
String>>#printOn:.

(so we can't use it any more).
* kernel/Date.st: Changed to reflect the changes required by
String>>#printOn:.
* kernel/Character.st: Changed character to always print with a
leading $.
* kernel/CompildMeth.st: Fixed printOn method to account for change to
String printOn:.
* kernel/Class.st: Implemented classVarNames and allClassVarNames.
Implemented sharedPools and allSharedPools.

1990-09-21 Steve Byrne <sbb@gnu.org>

* kernel/Bag.st: Removed printOn: method; the one from Collection does
the right thing.
* kernel/Set.st: Removed printOn: method; the one from Collection
is fine.
* kernel/LinkedList.st: Removed printOn: method; the one from
Collection should be ok. Also, the storeOn: method from Collection
should be ok.
* kernel/ArrayColl.st: Removed storeOn: method; doesn't seem to be the
right thing.
* kernel/Integer.st: Fixed printOn: to reflect the fact that String
printOn: no longer "does the right thing".
* kernel/Collection.st: Fixed store: to be storeOn:
* kernel/ClassDesc.st: Fixed the implementation of instVarNames to just
return the variables defined by the current class,
and added implementatinos of allInstVarNames and
subclassInstVarNames.
* kernel/Array.st: Added printOn: and storeOn: methods.
* kernel/Symbol.st: Added printOn: to print the un-sharped version of
the symbol, since string printOn: changed.
* kernel/Behavior.st: Changed allSubclassesDo: to use ALL subclasses,
both direct and indirect.
* kernel/Dictionary.st: Changed printOn: to print the associations directly.
* kernel/String.st: Changed printOn: to print with quote marks.
On re-reading the documentation it appears as if this
is the proper behavior (sigh).
* kernel/UndefObject.st: Fixed due to String printOn: change.

1990-09-20 Steve Byrne <sbb@gnu.org>

* kernel/SeqCollect.st: Fixed indexOfSubCollection (it was off by one and
did too much computation.
* kernel/Float.st: Fixed storeOn: to not be recursive.

1990-09-16 Steve Byrne <sbb@gnu.org>

* kernel/Behavior.st: Implemented whichSelectorsReferTo: and
scopeHas:ifTrue:.

1990-08-03 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added definition of CObject class alloc:.

1990-05-22 Steve Byrne <sbb@gnu.org>

*** Version 1.1.1 released (I think. I added this on 05 10th, 1999... --- pb)

1990-05-20 Steve Byrne <sbb@gnu.org>

* kernel/WriteStream.st: Fixed semantics of write streams so that they return
only the characters that have been written to them.
* kernel/RWStream.st: Fixed to accomodate changes in WriteStream.

1990-05-19 Steve Byrne <sbb@gnu.org>

* kernel/FileStream.st: Rewrite contents to take advantage of the new
FileStream>>size method.
* kernel/Stream.st: Added print: for streams.

1990-05-16 Steve Byrne <sbb@gnu.org>

* kernel/Character.st: Changed from being variableSubclass to
variableWordSubclass.
* kernel/Metaclass.st: Changed the implementation of name:... to
try to preserve an existing class (if possible).
The original code exists in newMeta:...
* kernel/Class.st: Improved error checking: you now cannot create a
subclass of a class whose type is not compatible
(i.e. non-variable subclass of a variable byte class).
* kernel/Class.st: Minor changes to support preserving class
definitions as long as possible (i.e. if you re-invoke the class
definition method, it tries to re-use the existing class if
possible).

1990-05-14 Steve Byrne <sbb@gnu.org>

* kernel/TokenStream.st: Removed isWhiteSpace:;replaced uses with
Character isSeparator.

1990-04-07 Steve Byrne <sbb@gnu.org>

* kernel/Dictionary.st: Modified at:put: to resuse the existing
Association if there is one, rather than create a new one all
the time. This was causing lossage when setting global variables
in Smalltalk that previous usages weren't being changed.

1990-05-06 Steve Byrne <sbb@gnu.org>

* kernel/Dictionary.st: Fixed grow method to preserve associations
in use in the dictionary instead of making new ones. This should
be faster, and doesn't break compiled methods that reference global
variables when Smalltalk grows.

1990-04-26 Steve Byrne <sbb@gnu.org>

* kernel/Object.st: Fixed shallowCopy to send new messages to the
object's class instead of the object itself.

1990-04-25 Steve Byrne <sbb@gnu.org>

* kernel/Integer.st: Fixed (oh...happy birthday, Integer.st!)
bitInvert. After fixing the lexer to be pickier about integer
literals that were too large to be represented as Smalltalk
literals, the previous code (which xored with 7fffffff) broke,
so we xor -1.

1990-04-24 Steve Byrne <sbb@gnu.org>

* kernel/Dictionary.st: Fix at:ifAbsent: to deal with failure
better (and be a tad more efficient). Kudos (or BarNone's,
depending on preference) to Andy Valencia.

1990-04-22 Steve Byrne <sbb@gnu.org>

* kernel/SysDict.st: Fixed Dependencies to be an IdentityDictionary
instead of a regular Dictionary. This has better semantics and
is faster.

1990-04-19 dougm

* kernel/Rectangle.st: Initial definitions for Rectangle
class (needs Point)

1990-04-16 dougm

* kernel/Point.st: Created basic Point class.

1990-04-15 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added sqrt primitive (I'm sure this was here
before) must have got lost during breaking out from builtins.

1990-04-07 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added declare tracing primitive.

1990-04-15 Steve Byrne <sbb@gnu.org>

* kernel/Float.st: Added asFloat...I could have sworn this was
already here...must have been lost in an edit.

1990-04-20 Steve Byrne <sbb@gnu.org>

* kernel/Builtins.st: Added SystemDictionary debug to help out
with DBX level debugging.

1990-02-11 Steve Byrne <sbb@gnu.org>

* kernel/FileStream.st: added fileIn: and primitive file in.

1989-09-23 Steve Byrne <sbb@gnu.org>

* kernel/ClassDesc.st: fileOutCategory: is dangerous, so I make it
write to a subdirectory called './categories'.

* kernel/Random.st: Created.

1989-06-04 Steve Byrne <sbb@gnu.org>
