Re: [Pharo-project] Alien and special objects Array

by Fernando olivero

Hi Torsten, strange because Alien used to crash on old images because it adds to slots to the special objects array, and since the indexes are hardcoded throughtout the whole image, it crashed after loading Alien. We fix that problem a while ago, and i've also added a initial loading check ( that validates that the special objects array is the requiered size). Could you tell us if you get that error? And more info on when it crashes? Saludos, Fernando pd: did the special objects array change in the last core?

ok I integrated the latest changes of Juan (he fixed some not consistent behavior and cleaned the code).

Re: [Pharo-project] Update 10458 fails with MNU

I published 48 in pharo but this is strange because we have the repository to gofer and I do not understand why this package is not found.

Thanks martin my mistake. indeed this is normally Gofer is not part of Pharo. But was used to I will copy the package for now in pharo. We should really discuss if we want to have installer or gofer in the core. Stef > Downloaded 09.09.3, install fresh, launch, System->update. > > Runs for a while, then fails while loading 10458.

Re: [Pharo-project] OT: vm performance

Well you can think different, some links below point to a status screen I did for a VisualWorks server application Red varies from 0-100 % and the sum of the other colors Green, Blue, Light Blue, and Purple are measured as state changes as work progressed for 4 different processes. http://smalltalkconsulting.com/clientSupport/L/opsguide/Image18.gif http://smalltalkconsulting.com/clientSupport/L/opsguide/Image17.gif http://smalltalkconsulting.com/clientSupport/L/opsguide/Image16.gif I think... goodness that was 12 years back, I did something like... footaskcounter := footaskcounter + 10. foo msg1 footaskcounter := footaskcounter + 10. foo msg2 footaskcounter := footaskcounter + 10. foo msg3 footaskcounter := footaskcounter - 30. As you can see from the gif files it was easy to look at the visual and understand what the application was *doing*. The support team could look at Image18.gif and fully understand what was happening. Operations only knew that Image18.gif was *normal* and that Image16.gif was the loss of the mainframe network data feed connection,. and for Image17.gif the image was doing nothing useful, idle, but not insane...

Thanks! I was thinking in terms of "anything but Smalltalk" to avoid the obligatory FUD and Mud slinging. However, it does sound like a useful idea, and if the code is already written, it can't hurt to see what it shows. If it flags something, then I can figure out whether I can get the IT types to believe it.

[Pharo-project] Update 10458 fails with MNU

by Martin McClure

Downloaded 09.09.3, install fresh, launch, System->update. Runs for a while, then fails while loading 10458. Failure is MNU. In [] in ScriptLoader>>loadTogether:merge: the code [:fn | loader addVersion: (self loadVersionFromFileNamed: fn)] Is failing, #loadVersionFromFileNamed: is answering nil when fn is 'Gofer-lr.48.mcz'. And, indeed my package-cache does not contain 'Gofer-lr.48.mcz', but it does have Gofer-lr.51.mcz. Regards, -Martin
