David T. Lewis uploaded a new version of Collections to project The Trunk: http://source.squeak.org/trunk/Collections-dtl.268.mcz ==================== Summary ==================== Name: Collections-dtl.268 Author: dtl Time: 31 December 2009, 5:57:13 am UUID: 70cf7086-91e9-4d1f-a078-eaf82e6208fb Ancestors: Collections-ul.267 Add remaining portions of NewSystemTracer-ajh, with classes and methods recategoried to SystemTracing. =============== Diff against Collections-ul.267 =============== Item was changed: Stream subclass: #PositionableStream instanceVariableNames: 'collection position readLimit' + classVariableNames: 'IntBuffer' - classVariableNames: '' poolDictionaries: '' category: 'Collections-Streams'! !PositionableStream commentStamp: '<historical>' prior: 0! I represent an accessor for a sequence of objects (a collection) that are externally named by indices so that the point of access can be repositioned. I am abstract in that I do not implement the messages next and nextPut: which are inherited from my superclass Stream.!

Andreas Raab uploaded a new version of Collections to project The Trunk: http://source.squeak.org/trunk/Collections-ar.268.mcz ==================== Summary ==================== Name: Collections-ar.268 Author: ar Time: 31 December 2009, 8:00:38 am UUID: d7d8920f-95b8-bd48-80d1-ccca70274fb6 Ancestors: Collections-ul.267 Enhancements to Collection>>do:displayingProgress:. The new version has two additional features: It allows the provision of a block argument for the label instead of a string, i.e., Smalltalk allClasses do:[:aClass| (Delay forMilliseconds: 1) wait] displayingProgress:[:aClass| 'Processing ', aClass name] The second addition is an update limit that ensures that we're not spending our time in display updates. When the update limit is zero, we will update every round through the iteration, see: (Smalltalk allClasses) do:[:aClass| (Delay forMilliseconds: 1) wait] displayingProgress:[:aClass| 'Processing ', aClass name] every: 0. whereas with non-zero argument we only do this every n msecs: (Smalltalk allClasses) do:[:aClass| (Delay forMilliseconds: 1) wait] displayingProgress:[:aClass| 'Processing ', aClass name] every: 200. The default update limit is 20ms which should be a pretty good general choice. =============== Diff against Collections-ul.267 =============== Item was changed: ----- Method: Collection>>do:displayingProgress: (in category 'enumerating') ----- + do: aBlock displayingProgress: aStringOrBlock + "Enumerate aBlock displaying progress information. + If the argument is a string, use a static label for the process. + If the argument is a block, evaluate it with the element to retrieve the label. + Smalltalk allClasses + do:[:aClass| (Delay forMilliseconds: 1) wait] + displayingProgress: 'Processing...'. + Smalltalk allClasses + do:[:aClass| (Delay forMilliseconds: 1) wait] + displayingProgress:[:aClass| 'Processing ', aClass name]. + " + ^self do: aBlock displayingProgress: aStringOrBlock every: 20! - do: aBlock displayingProgress: aString - - aString - displayProgressAt: Sensor cursorPoint - from: 0 to: self size - during: - [:bar | - self inject: 1 into: - [:index :each | - bar value: index. - aBlock value: each. - index + 1]]!

I am responsible for encoding and decoding various kinds of compiled method trailer data. I should not expose any binary data outside of myself, so all tools which working with compiled methods should ask me to encode the meta-data, they want to be added to the compiled method trailer, as well as retrieve it. To add a new kind of trailer, you should give it a proper name and define it in the #trailerKinds method at my class side. + Then you need to implement a corresponding #encode<your name> and #decode<your name> methods at instance side. Then add any public accessor methods, which will use a newly introduced trailer kind for communicating with outer layer(s). And finally evaluate: self generateTrailerKindDecoders. - Then you need to implement a corresponding #encode<your name> and #decode<your name> methods at instance side. Then add any public accessor methods, which will use a newly introduced trailer kind for communicating with outer layer(s). An encodeXXX methods should store result (byte array) into encodedData instance variable. A decodeXXX methods should read the data from compiled method instance, held by 'method' ivar, and always set 'size' ivar (denoting a total length of trailer in compiled method) and optionally 'data' ivar which should keep a decoded data, ready to be used by outer layer(s) using accessor method(s) you providing. The kind of compiled method trailer is determined by the last byte of compiled method. The byte format used is following: "2rkkkkkkdd" where 'k' bits stands for 'kind' , allowing totally 64 different kinds of method trailer and 'd' bits is data. Following is the list of currently defined trailer kinds: NoTrailer , k = 000000, dd unused method has no trailer, and total trailer size bytes is always 1 ClearedTrailer, k = 000001, method has cleared trailer (it was set to something else, but then cleared) dd+1 determines the number of bytes for size field, and size is a total length of trailer bytes So a total length of trailer is: 1 + (dd + 1) + size TempsNamesQCompress, k = 000010 the trailer contains a list of method temp names, compressed using qCompress: method. dd+1 determines the number of bytes for size field, and size is a number of bytes of compressed buffer. So a total length of trailer is: 1 + (dd + 1) + size TempsNamesZip, k = 000011 the trailer contains a list of method temp names, compressed using GZIP compression method. dd+1 determines the number of bytes for size field, and size is a number of bytes of compressed buffer So a total length of trailer is: 1 + (dd + 1) + size SourceBySelector, k = 000100 the trailer indicates , that method source is determined by a class + selector where it is installed to. Trailer size = 1. SourceByStringIdentifier, k = 000101 the trailer indicates , that method source is determined by a class + some ByteString identifier. dd+1 determines the number of bytes for size of ByteString identifier, and size is number of bytes of string. A total length of trailer is: 1 + (dd + 1) + size EmbeddedSourceQCompress, k = 000110 the trailer contains an utf-8 encoded method source code, compressed using qCompress method dd+1 determines the number of bytes for size field, and size is a number of bytes of compressed source code A total length of trailer is: 1 + (dd + 1) + size EmbeddedSourceZip, k = 000111 the trailer contains an utf-8 encoded method source code, comressed using GZIP dd+1 determines the number of bytes for size field, and size is a number of bytes of compressed buffer A total length of trailer is: 1 + (dd + 1) + size VarLengthSourcePointer, k = 001000 the trailer is variable-length encoded source pointer. dd bits is unused. ExtendedKind, k = 001001 the next byte of trailer (one that prepends the last byte of compiled method) denotes an extended kind of trailer, allowing to use additional 256 kinds of encoding method's trailer in future. SourcePointer, k = 111111 the trailer is encoded source pointer. Total trailer size is 4-bytes (this kind of encoding is backwards compatible with most of existing compiled methods) !
