Re: [Pharo-project] Don't ask me how to reproduce this one :)

by Andrew Tween

Hi Bill, Using a freshly downloaded pharo1.0-10418-BETAdev09.08.3.image , under Windows Vista, it fails after the 19th save. (which seems to makes sense, since there are two font faces being displayed, and I know that the max number of open file handles before failure is 37. 19 x 2 = 38, which is > 37) Cheers, Andy . > From: bschwab(a)anest.ufl.edu > To: Pharo-project(a)lists.gforge.inria.fr > Date: Tue, 1 Sep 2009 07:01:53 -0400 > Subject: Re: [Pharo-project] Don't ask me how to reproduce this one :) > > > Damien, Andy, > > That's a fair question.

Re: [Pharo-project] Startup/shutdown

by Schwab,Wilhelm K

Damien, I'm still trying to figure out whether or not it should be lost :) Will do though. However, the real benefit will be to move all of the memory management to it or something like it. I am still a little surprised (or is it made suspicious by?) the fact that it appears to be possible to do with the information the image has now. Part of me wonders <somebody's gotta say it>why in the hell</somebody's gotta say it> nobody dealt with it years ago. Not having to litter code with extraneous network iniializations should be enough motivation to do something so simple, assuming it is indeed so simple.

Damien, Andy, That's a fair question. Do we have any idea how many saves should be required to cause the failure?
