[Pharo-project] fuel configuration was broken

by Tudor Girba

Hi, The Moose build fails because the Fuel configuration is broken. In particular, in baseline15: there was an error because FuelWithProgressBarBenchmarks was not defined anymore, but it was required. So, I simply removed the requirement. Martin, please take a look. Please pay attention when building a new version in a Metacello configuration because Metacello tries to reify every version in the Configuration, even if that version is not used. I keep on arguing that this is not a good thing, but at the moment we have to pay more attention :). Cheers, Doru -- www.tudorgirba.com "Live like you mean it."

Re: [Pharo-project] how can I get bit representation of numbers

This is what I do, for reading/writing unsigned or two complement signed integer from/to byte streams. Note that two complement is only defined for a specific number size, 8, 16, 32 bits. unsignedToSigned: integer size: size ^ integer < (2 raisedTo: size - 1) ifTrue: [ integer ] ifFalse: [ (self twoComplement: integer size: size) negated ] signedToUnsigned: integer size: size ^ integer negative ifTrue: [ self twoComplement: integer size: size ] ifFalse: [ integer ] twoComplement: integer size: size | mask | mask := (2 raisedTo: size) - 1. ^ mask bitAnd: ((integer abs bitXor: mask) + 1) These are also very handy in this context (I believe I once submitted that as an issue): integerFromByteArray: bytes | integer | integer := 0. bytes withIndexDo: [ :each :index | integer := integer + (each bitShift: (bytes size - index) * 8) ]. ^ integer and Integer>>#asByteArrayOfSize: Once you have a byte representation, you can render it as bits as well.

yes... I'm aware of the graphics problem, but I still don't know what is causing it (it not happens with pharo 1.2 or squeak, so I think is a combination of "something" in vm side -cocoa version, that "something" in pharo changes brought to front). I will work on that some time this week :) In the near future, the only version of cog vm should be cocoa version, but there are still some remaining issues who prevents ppl to adopt it (not very big issues, and there are a lot less issues now, but still some remain). I think one of the main reasons is that both Eliot and Igor are working on the carbon version, not the cocoa one (for historical reasons: cocao version didn't exist when Eliot started working on Cog). I would love to join those efforts and drop carbon version (which is legacy), but I don't think it will happen any time soon, sadly :( This are the issues preventing people to adopt cocoa version (at least those I can see now): 1) Not enough plugins. This is SOLVED, currently, hudson builds came with almost all the plugins provided for old carbon versions (4.2.x) 2) No MacMenusPlugin. Still there. Not a big issue, as we can live without them, but it will be nice :) 3) This annoying graphics problem... I hope to solve it soon. 4) I didn't release a 6.0 stable version (because of the graphics problem, now) :) cheers, Esteban El 04/07/2011, a las 5:13p.m., Eliot Miranda escribiÃ³: > > > On Mon, Jul 4, 2011 at 1:05 PM, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > On Jul 4, 2011, at 10:02 PM, Camillo Bruni wrote: > > > > > On 2011-07-04, at 21:34, Marcus Denker wrote: > > > >> > >> On Jul 4, 2011, at 9:25 PM, Marcus Denker wrote: > >> > >>> > >>> On Jul 4, 2011, at 9:24 PM, Lukas Renggli wrote: > >>> > >>>> The tests also hang with the Inria build of Cog. > >>>> > >>> I just did run all the tests and it did not hang... > >>> > >>> Very strange. > >>> > >>> (Of course there are *two* Cog Vms for Mac... and I use the other one) > >>> > >> > >> I managed to reproduce the graphics bug. > >> > >> It only happens with the Cocoa VM. > >> > >> I have personally not used the cocoa branch the last months...

If you get nothing = Carbon/old if you get a file path its the Cocoa/new :)

This problem is know. It happened to me always with Pharo 1.3 and cocoa VMs. In fact, Esteban is also aware.
