Constructing a patched Monticello package without installing it
by Eliot Miranda Jan. 15, 2014

Jan. 15, 2014

Hi All, I'm trying to deploy Spur in our Newspeak bootstrap at Cadence. The starting point for the Newspeak bootstrap) is a Squeak4.3 image. I have a Squeak4.3 image transformed by the Spur bootstrap to Spur format, which means it has a few method modifications to three packages: Collections (changed Character methods now that Characters are immediate) Kernel (changed Behavior & ClassBuilder changes now that a class's format has changed, and instantiation interacts with the garbage collector differently) System (changed SystemDictionary/SmalltalkImage methods now that there's a generation scavenger) The Newspeak bootstrap loads versions of these packages that support Newspeak. So the problem is to load the Newspeak versions of these packages without undoing the Spur bootstrap modifications. As a quick hack I could patch the Monticello loader to avoid the modifications (they're marked by not having a source pointer but could be marked in some other way, e.g. a pragma). That's a fine simple approach. But... I just stumbled across Monticello's MCPatcher and the Backport button which claims to apply a partial delta to the ancestor of a package. Does anyone who understands this code know if the code supports loading a package, without installing it, applying a partial set of changes (i.e. the relevant changes form the bootstrap) and saving the package as an mcz? If it does then I could construct patched versions of the three packages and substitute them in the bootstrap instead of using the hack. -- best, Eliot

Beware Issue 12657 Nautilus: Method DND explodes
by Sean P. DeNigris Jan. 15, 2014

Jan. 15, 2014

Nasty one: Drag method from one open Nautilus to a class in another browser. 1. The method disappears from the original class, but is not listed as removed in MC changes 2. The method does not appear in the target class ----- Cheers, Sean -- View this message in context: http://forum.world.st/Beware-Issue-12657-Nautilus-Method-DND-explodes-tp473… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Recordable bug reports
by Sean P. DeNigris Jan. 15, 2014

Jan. 15, 2014

Kind of a cool use for EventRecorderMorphâ¦ I noticed this method comment: "In case there is a chance of not regaining control to stop recording and save a file, the EventRecorder can write directly to file as it is recording. This is useful for capturing a sequence that results in a nasty crash." You could record the steps to reproduce a bug with EventRecorderMorph, save it to a tape file, and attach it to the bug report. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Recordable-bug-reports-tp4736970.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Ok, testing a bit and I can't see much of a problem, except ... something really annoying ... Why is the tag disappearing if I move the only class in it to another package?
