Hi list, we (with Stef) are browsing Kernel-Extensions, here are some
notes for discussion, as we think there is stuff that should be merged
in Pharo.
Null and Split-Join could be packaged on their own since they are
well-defined features.
Most of the cleanup methods make sense, but what's the difference
between cleanUp and freeSomeSpace ?
AppRegistry class >> removeObsolete
"AppRegistry removeObsoleteClasses"
self registeredClasses copy do:[:cls|
(cls class isObsolete or:[cls isBehavior and:[cls isObsolete]])
ifTrue:[self unregister: cls]].
self subclasses do:[:cls| cls removeObsolete].
Behavior class >> flushObsoleteSubclasses
"Behavior flushObsoleteSubclasses"
ObsoleteSubclasses finalizeValues.
Behavior >> sourceMatchesBytecodeAt:
Class class >> freeSomeSpace
"Fix some problems with classes. Use Smalltalk allClassesDo: since it
does not use the subclass list, which we may be modifying during this
iteration"
Smalltalk allClassesDo: [:ea |
ea fixObsoleteSuperclass.
ea removeDuplicateSubclassEntries]
Collection >> contains: should probably be standardized as part of
the STEPS project
Collection >> reject:thenDo: and select:thenDo: should be
included and similar enumerations reimplemented in this way too
SystemDictionary >> forgetClass: aClass logged: aBool badly
named but interesting
"Delete the class, aClass, from the system.
Note that this doesn't do everything required to dispose of a class -
to do that use Class>>removeFromSystem."
aBool ifTrue: [SystemChangeNotifier uniqueInstance classRemoved:
aClass fromCategory: aClass category].
SystemOrganization removeElement: aClass name.
self removeFromStartUpList: aClass.
self removeFromShutDownList: aClass.
self removeKey: aClass name ifAbsent: [].
DataStream classRemoved: aClass.
self flushClassNameCache
SystemDictionary >> globals needs to pay attention that compiled
methods share the associations
Number >> to: stop do: aBlock displayingProgress: aString would be
probably nicer with the block argument last
=== To discuss:
Collection >> removeAll: comment should explain in which cases it is useful
"the slow way"
^ self removeAllSuchThat: [ :each | true ]
SequenceableCollection >> <= smells funny… what is it useful for ?
SequenceableCollection >> replacing:with: replaces in place, not
obvious from the name
the stream methods like putOn: … convenience ? are they coherent ?
String >> withoutTrailing: probably makes sense but then this is
mostly useful for line breaks… why not a #trimLinebreak
Set >> likeOrAdd: ok but then that should be available for any
collection (and renamed addIfAbsent:)
"Include newObject as one of the receiver's elements, but only if
not already present. Answer the oldObject."
=== Useless:
ProtoObject >> iconOrThumbnailOfSize:
Object >> askFor: and askFor:ifDefault: that's a workaround
Object >> deprecated is already here
Object >> log should be packaged in a logging package since it's a
convenience method
SequenceableCollection >> copyReplacing:with: just to type one space less ?
