tracking down change sets for a class
by Ross Boylan 01 May '05

01 May '05

I'm considering the best approach to migrating an image and application which are at 3.6. I thought it would be useful to review relevant changesets, especially the pre and post code that handles migration (I guess such code could also be embedded in doIt's). I am not having much luck. I'd like a "see all changesets with class X" (or see all entries relating to the class), but the closest I've found to that is to find a method in the class, browser versions, and go to the changeset. (I think I used those other, desired, functions in VisualWorks. Maybe squeak doesn't have them.). The problem is that in some cases there is no changeset. For example, between 3.6 and 3.7 ScrollPane acquired horizontal scrollbars. But even using a 3.7 image and looking at methods involving them (#hMargin) it tells me it can't find a change set. Earlier postings on the list indicated that sometimes the changesets are dropped, but this is a change that's very recent, relative to 3.7 (i.e., it first appeared in 3.7). Narrowly, I'd appreciate any help tracking down the changeset(s). More broadly, I'd appreciate any advice on migration. I'm in a particular bind because of the introduction of DateTime in 3.7, which required lots of instance mutations, renaming, etc. I have already introduced those changes into my image--but in slightly different form (I created new classes with names like DTDate to avoid messing with the standard ones. In contrast, the official change stream does mess with them). Thanks. Ross Boylan

Clickstate recursion bug affects mouse focus(see mantis#1037).
by Peace Jerome 01 May '05

The clickstate processing seems to lose mouse focus after the first click. This is at least true with DoubleClickExample. Gory details have been added to mantis bug #0001037 along with probes to identify the problem. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
