[Pharo-project] Don't ask me how to reproduce this one :)
Hello all, I periodically see a degradation of anti-aliased fonts, and have no idea what causes it. Given my recent adventures in to startup/shutdown, I suppose it could be due to a problem there?? It seems to be triggered by saving the image w/o quitting. This recent occurance was different in that I started noting that the text in browsers looked different to me, perhaps just that the method name was not bold?? Something was not quite right, but the text still looked to be rendered well. Shortly thereafter, the full breakdown happened with everything rendered in an ugly font. It seems safe to save the image in this state, and exiting and re-loading the image fixes is. Any ideas? Bill

I had the truetype fonts disappear but doing FreeTypeFontProvider current updateFromSystem. fixed it. I don't know if that's the correct way to do it though

Bill, I noticed that in the #10419 episode. HTH
Hi Bill, I can reproduce this by repeatedly saving without quitting (on windows vista). I suspect that some face handles are no being closed properly at shutdown. When a face handle is open, then the FreeType library also has the associated file open. But there is a limit to the number of open file handles - see http://code.google.com/p/pharo/issues/detail?id=1061 for more info on this. When I have figured out what is going wrong in the shutdown, I'll post a fix. Is there a bug issue number for this problem? If not, I'll create one. Cheers, Andy .

Andy, It is not a big problem. When it happens, I simply close the image and re-open it. Clearly any memory leaks should be fixed, but I might be able to help a little; I appear to have something that can tell when an image opens and when it closes, and that is an important part of Dolphin's standard approach to external resources. Perhaps it is just my Dolphin bias showing, but it strikes me as something that needs to be fixed, and I would like to have others test it to look for problems. I will try to follow this with a separate message that will make the code easier to load.

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 .
