[Pharo-project] about bufferedFileStream

by StÃ©phane Ducasse

Hi levente I was wondering why the bufferedFileStream made the system faster. I mean are querying the same contents on several occasion? Stef

Re: [Pharo-project] [newbee] How do I save the contents of a Workspace?

by Schwab,Wilhelm K

Thanks for doing this! How did you modify the menu? I have *no* clue how to do that. Two comments, the first horribly pedantic. The prompt for the file name reads "Enter file name to save the workspace to" - we have no shortage of dangling prepositions. "Ener file name" would be preferable. More substantively, it does not prompt for a directory. I agree that the image directory is the most likely default, but Pinesoft probably has given us a suitable file dialog, and if not, we should identify the omission.

If this is useful it does not hurt us. So I did it :). See on the tracker http://code.google.com/p/pharo/issues/detail?id=1859. I started from the changes, mentioned here by Keith Hodges, but it turns out that I used them for inspiration almost :) (Thanks Keith!). The result is completely different from what you have now in Squeak. You have now association with the file and you don't have to enter file name every time you want to save file as you do in Squeak. And as someone suggested here the default extension is .ws. I hope it will be useful.

[Pharo-project] Question about ImageSegment, Symbols and SmartRefStream

by Mariano Martinez Peck

Hi folks. I am writing some ImageSegment tests and there is something I don't know how it is done. I create a segment with a root (array) that has symbols inside. Then, I export the segment using the method ImageSegment >> writeForExportOn: which uses a SmartRefStream to serialize itself and write it to a file. Now...the situation is like this: I hold the symbols so that they go to outPointers instead of wordarray. When I export the segment using writeForExportOn: the objects from outPointers should be exported also. Case 1) I export the segment and then load it in an image where the symbols are not present, and after the load, the symbols are present (and they came from the outPointers)...This is correct Case 2) I export the segment and then load it in an image where the symbols ARE ALREADY present, and after the load, the symbols ARE NOT duplicated...Ok..this is cool. But how does this magic happens ? Why I don't have two symbols equal ? If need the unit tests of both cases, I can past it here. Any ideas where this black magic comes from ?
