Re: [Pharo-users] Memory profiling: usage per class - instance in old memory

by Stephan Eggermont

Your calculation seem to be off. 32 * 86400 objects = 2.8 million objects. A shortint = 4 bytes, making 10.6 MB Everything else (except value objects) is larger. Stephan

Memory profiling: usage per class - instance in old memory

by Thomas Bany

Hi, My app is a parser/filter for binary files, that produces a bunch of ascii files. At the begining of the parsing, the filtering step involves the storage of the positions of 32 objects, each second for a whole day. So that's 32 Arrays with 86400 elements each. During this step, the memory used by my image grows from 50Mb to ~500Mb. I find it far too large since I'm pretty sure my arrays are the largest objects I create and only weight something like 300kb. The profiling of the app shows that hte footprint of the "old memory" went up by 350Mb. Which I'm pretty sure is super bad. Maybe as a consequence, after the parsing is finished, the memory footprint of the image stays at ~500Mb What are the tools I have to find where precisely the memory usage explodes ? For example, is it possible to browse the "old memory" objects to see which one fails to get GC'ed ? Thanks in advance, Thomas.

Thanks, Stephan. I will have a look and try to load/use Glorp myself towards the end of the week.

I think you can have your mock send an exception by using #answers:aBlock and signal the exception in the block 2014-04-08 15:58 GMT+02:00 Christophe Demarey <Christophe.Demarey(a)inria.fr>: > Hello, > > Thanks.

Re: [Pharo-users] Error: No factory specified

by Stephan Eggermont

Ok, there is a bug in The ConfigurationOfDBXDriver, the baseline has a versionString entry. That should be removed After removing that (and renaming Cache) it loads. Glorp loads already after renaming Cache. Iâm not sure the isKindOf: on ProtoObject is safe. There is a renaming issue after loading Glorp (13188) Stephan

How to remap a keyboard?

by Norbert Hartl

I need to develop something in linux at the moment. I use virtualbox with linux on my mac laptop. It is basically ok to work with it but the keyboard mapping is not ok for pharo. I configured the keyboard on the linux to be German (Macintosh) but the special keys are all wrong. Being a long time linux/open source guy I know it will be a major pain to tweak it in linux (I think I did the last time with xkeymap 15 years ago). On the opposite I have the advantage of learning something new if I tweak the mapping in pharo instead of the operating system. So which would be the entry points in pharo if I want to remap my keyboad? Meaning rearranging the association of a bunch of keycodes to the interpreted character. thanks, Norbert
