Cycles lost on startup
by Eliot Miranda Sept. 8, 2016

Sept. 8, 2016

Hi All, we are simulating a full block Pharo image derived from Pharo 6. On startup we see a very sad loss of cycles due to a very slow rebuild of the selector table in Symbol class. Why is this done at each startup? Here is the stack: 16r107154 M ByteString class(ProtoObject)>identityHash 16r786AE8: a(n) ByteString class 16r10716C M ByteString class(Object)>hash 16r786AE8: a(n) ByteString class 16r10718C M

class>selectorTable calls Symbol class> initSelectorTable which then calls CompiledMethod class(Behavior)>allInstancesDo: to enumerate over all methods. This takes a significant amount of time, even on a fast machine. For example, on a 2.%GHz machine this takes about 70 milliseconds. That's a /lot/ of time to squander on startup. And it will grow the larger the image is. The selector table seems to be discarded on shut-down, which seems pointless. If one wants to recompute the table then before or after methods are added or removed seems like a better choice, not on every image startup. In around 2000 we were able to startup VisualWorks images in about 40 milliseconds on the hardware available at the time. I hope someone reconsiders this code and a avoids recomputing the selector table on each startup. _,,,^..^,,,_ best, Eliot

Small OS-... project addition
by Torsten Bergmann Sept. 8, 2016

Sept. 8, 2016

Hi, now also the OSX project in the OS series [1] has support to - directly open a terminal - directly open a file browser (Finder) on the working directory right from the Pharo tools menu. See attached screenshot. Depending on your platform just load - OSOSX - OSWindows - OSLinuxUbuntu - OSLinuxCentOS from catalog. Bye T. [1] http://smalltalkhub.com/#!/~OS

Deactivated Locale Still Sets TimeZone
by Sean P. DeNigris Sept. 8, 2016

Sept. 8, 2016

I was surprised to find that Pharo kept setting my local offset, even though I explicitly set it to UTC and then made sure Locale was disabled. Then I saw: Locale class>>#startUp: resuming ... DateAndTime localTimeZone: self localTimeZone. (self activated) ifTrue: [ First it does some work, and then it checks to see whether it's activated! I propose to move the first line into the subsequent block, or maybe better yet - move that behavior into DateAndTime itself. Thoughts? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Deactivated-Locale-Still-Sets-TimeZone-tp4914754.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

[ANN] FreeType binding
by Thibault Raffaillac Sept. 7, 2016

Sept. 7, 2016

Hello, I am happy to announce the release of a new FreeType binding :) http://smalltalkhub.com/#!/~ThibaultRaffaillac/UFFIFreeType I use it to render glyphs with OpenGL, so a few features are still missing compared to FT2: gamma-space blitting (should belong to OSWindow?), GlyphForm class, and subpixel rendering (patch GlyphSlot>>form). FT_Library startUp: true. face := FT_Face fromFile: 'Arial.ttf' index: 0. glyph := face glyph. face setPixelWidth: 0 height: 12. face loadChar: $x asUnicode flags: 4. image := glyph form. Cheers, Thibault
