[Pharo-project] Why Sets need to be rehashed when loading them from an ImageSegment?

by Mariano Martinez Peck

Hi. I was almost sure that Set instances that were written in an ImageSegment, needed to be rehashed once they are swap in. And I even thought I was understanding why. But now, I don't understand at all why is that. I would really appreciate anyway that can give me a hint. So...ImageSegment rehashes all Set instances (at loading time) that were written in an ImageSegment, and then exported with ReferenceStream. Notice that this rehash is finally called from ImageSegment >> comeFullyUpOnReload: smartRefStream. When you export an ImageSegment with a reference stream, you also serializer the "outPointers" array. This is usually the case when you want to load the object subgraph in another image or when do it backups so that to start with a clean image. Notice that the Set rehash only occurs in this case. If we use ImageSegment just to swap out / in, there is no Set rehash. So...I think that this has something to do about WHY Set instances need to be rehashed. For each object ImageSegment write into the file, it writes both: object header + slots. So....the hash (12 bits in the object header) is copied. When the object is loaded back, it continues to have the same hash. It doesn't change. So...if hash doesn't change, why Set instances need to be rehashes when they come back from an ImageSegment? Thanks in advance, Mariano

Updates: Cc: stephane.ducasse Comment #3 on issue 3523 by Torsten....(a)astares.de: Nested comments http://code.google.com/p/pharo/issues/detail?id=3523 I think your problem comes from writing the documentation in the usual tools like class browser, etc. where you edit a string (with all the '' escaping) Maybe you should use the EDIT SUPPORT of help system. Example: 1. Create a simple subclass of CustomHelp for a new book. CustomHelp subclass: #MyHelpBook instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'MyApp-Help' 2. Implement a class side method to name the book: bookName ^'Help for MyApp' 3. Now edit page you want by evaluating MyHelpBook edit: #page1 => this opens a new workspace where you can write your documentation similar to class comments. If you change the title of the window you will give your page a name. => If you accept the contents of this workspace it will be saved in the method #page1 4. Implement the method to return the books pages: pages ^#(page1) You dont have to fight with string escaping then
