[Pharo-project] SqueakMap Package Loader?
by Markus Fritsche April 20, 2009

April 20, 2009

I just tried to start a SM Package loader which issued a dnu. Is it my image or is ImageSegment broken? Is SM deprecated? It seems so in the official squeak distribution...

[Pharo-project] Some visual artifacts in buttons (Watery 2 theme)
by Igor Stasenko April 20, 2009

April 20, 2009

Hello, just in case if you not already seen it.. These artifacts (a button labels blended with background) is appear only, when you draggin a morph in hand. If you just place morph over background - no visible artifacts appear. On screenshot, the button label is blended with Pharo logo, placed on background. It seems like somewhere, it not sets an opacity values correctly for button labels, which allows you to see through the cached form (which used when you dragging morph in hand). -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] About literalsDo: deprecation
by Nicolas Cellier April 20, 2009

April 20, 2009

I notice while scanning Eliot changes that #literalsDo: is a deprecated message... But (literals do:) replacement is not neutral concerning speed. It creates an Array where literalsDo: did not. This is not a detail because this is called on each and every method when scanning code: For example, I tried this in Pharo image: Time millisecondsToRun: [SystemNavigation default allGlobalRefs] ->5356 with Eliot's literalsDo: ->8947 pharo version calling literals do: This change spoils a few minutes out of our every day work ;) Nicolas

Did anyone experimented an Infinite loop in Monticello MCWorkingCopy needsSavings ? I had a SLICE previously saved. I added a new required pakage dependency to this SLICE. I tried to save again -> InfiniteLoop...

[Pharo-project] Pharo freezing ...
by stepken April 19, 2009

April 19, 2009

Hi! http://code.google.com/p/pharo/wiki/SmallLintPharoFixing While filtering with SmallLint Pharo freezes (Windows version). I think, there is elementary something going wrong there ... design problem? Maybe that's the same bug, that made Seaside suddenly freeze? Have fun, Guido Stepken

[Pharo-project] A little font rendering speedup
by Igor Stasenko April 19, 2009

April 19, 2009

This is an image-side change, which makes a primitiveDisplayString to not fail because StrikeFontSet returns nil for (font characterToGlyphMap). Since the code, which using fast primitive looks like following: self primDisplayString: aString from: startIndex to: stopIndex map: font characterToGlyphMap xTable: font xTable kern: kernDelta I thought, why one would return nil in ( font characterToGlyphMap ). Since #xTable in StrikeFontSet implemented as following: xTable "Answer an Array of the left x-coordinate of characters in glyphs." ^ (fontArray at: 1) xTable. i think it is safe to do similar in characterToGlyphMap , this allows the primitive to work w/o failure, because otherwise, if you look at implementation of primDisplayString: aString from: startIndex to: stopIndex map: glyphMap xTable: xTable kern: kernDelta in fallback code it does same thing again (and ignoring glyphMap at all, btw). To bench a difference, leave a couple of windows with text in world and then do: [10 timesRepeat: [World fullDrawOn: World assuredCanvas] ] timeToRun before change: 645 after change: 545 P.S. since i did this in a fresh pharo-10284-dev, where changesorter is completely broken(do you aware of it?), i filed out this method as .st file. -- Best regards, Igor Stasenko AKA sig.
