[Pharo-project] serializing object graphs / ordering graph anchors
by Norbert Hartl June 3, 2011

June 3, 2011

Before I start a utility myself I want to ask if there is such a tool already. I'm using sixx for object graph serialization. It works quite good but it has some severe limits. Well, the limits are not really sixx dependent but a problem of usual serializers. My problem is the size of the stack such a tool generates. Especially in gemstone this appears to be a problem because the stack is limited per gem. If I look at the serializers I know the mechanics are simple: 1. take an object and look it up in a table. 2. if the object is in the table it has already been serialized. We take a reference from the table and write it down 3. if it isn't in the table it means the object has not been serialized and the contents need to be written. After that the object with a reference representation is written to the table 4. while writing the content of an object (inst vars) I encounter simple objects (direct string representation) or complex objects (composite). In the latter case we start over from 1. If the object graph is well interconnected than the odds are high that a stack will grow high until the first reference can be written. With a small pier kernel I already matched a stack size of 1000. One solution I can think of is to collect and order objects in the graph that cover smaller segments from the overall graph. This way I would construct a sorted collection that is sorted by stack depth (lowest first). The collection will then be serialized leading to a much smaller possible stack sizes. It might be there are cases it can't work but I think for most cases it will do its job. And it will be slow of course. Does anybody know if such a tool exists? Norbert

[Pharo-project] 1.2.2 First Impression
by Sean P. DeNigris June 3, 2011

June 3, 2011

I moved from 1.1.1 to 1.2.2 for my development work and wanted to share some things I noticed... Overall, 1.2.2 feels cleaner, snappier, and prettier. My Favorite Things: * OCompletion is really fast!!! * Creating new method protocols - you can type spaces * Help System starting to fill out, and easily accessible from the World Menu Bugs / Regressions (I don't have time to check if each is still true in trunk) * Debugger * the current statement is highlighted in "invisible blue". It's impossible to see. * Creating an accessor - "should be implemented" is highlighted, which is good; but the window doesn't have focus, and clicking on the window's title bar doesn't give the source pane focus * Choosing a protocol for a created method - the selection doesn't jump to the first matching category name like it did in 1.1.1 * OB * Syntax errors - "Nothing more expected ->" is not highlighted, making you have to first select it before you delete it and correct your mistake * Surrounding selected text (e.g. with quotes) - the surrounded text doesn't stay highlighted (the 1.1.1 behavior, which I found very useful) * Monticello - After changing a category name to a sub-category of a different package (e.g. "MyLibrary" -> "MyOtherProject-MyLibrary"), the package is not marked dirty in the MC browser until changes are viewed. I'm really excited to see what comes next!! We're creating a great system.
