So Zinc is one of the pieces of software I know that do not assume stupid defaults :) Did you specify a proper Content-Type header including the charset information? Otherwise Zinc has no chance of knowing what to use and the default NullEncoder will make your string as wrong as your example above. Norbert

LOL. So you have no choice but to prepare for me an archive with your compiled VM, so I will use it ;-) (my system use glibc 2.15 anyway) Hilaire Le 09/04/2014 14:29, Bernat Romagosa a Ã©crit : > Ouch! I think it was myself who compiled it... I'll check again tomorrow! > -- Dr. Geo http://drgeo.eu

Socket Handles to C

by Sean P. DeNigris

How do Socket handles map to C socket IDs? I'm wrapping libssh2 via Native Boost and I'd much rather create sockets via Smalltalk than C, but I'm not sure how to pass the handle to a C function expecting a C socket ID. Maybe I'm missing something really simple? Thanks. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Socket-Handles-to-C-tp4753619.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Zinc HTTP server seems to convert always ...

by Sven Van Caekenberghe

Hi Marten, I will need (much) more detail, what are you trying to do that is not working according to you ? As far as I know Zinc HTTP Components does the right thing and can be used (configured) to do almost anything you want. It mostly depends on your mime types and their charset options.

Zinc HTTP server seems to convert always ...

Hey, it seems to me, that Zinc - out of the box - seems to convert from/to UTF8. How can I tell Zinc to do NO conversion and that ZnStringEntity should leave their strings as they are .. I am fighting here with German Umlauts Marten -- Marten Feldtmann

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

by Sven Van Caekenberghe

Hi Thomas, Fixing memory consumption problems is hard, but important: memory efficient code is automatically faster in the long run as well. Your issue sounds serious. However, I would start by trying to figure out what is happening at your coding level: somehow you (or something you use) must be holding on too much memory. Questioning low level memory management functionality should be the last resort, not the first. There is SpaceTally that you could use before and after running part of your code. Once something unexpected survives GC, there is the PointerFinder functionality (Inspector > Explore Pointers) to find what holds onto objects. But no matter what, it is hard. If you have some public code that you could share to demonstrate your problem, then we could try to help.

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

by Thomas Bany

I meant a single array weight something like 300Kb with the 32 of them weighting arround 10Mb. I tried to look closely at the way the memory (with VirtualMachine>#memoryEnd) was incrementing and it follows this pattern: - The memory costly function is defenitly the one storing my position arrays: #setPositionECEFOn: - Throughout the computation of the 32 daily positions, the memory used by the VM goes from 52Mb to 363Mb. Is this a normal behaviour ? On a side note, the computation of a single epoch (which is done 32*24*3600 times) uses 19 local variables. Not sure it is relevant. 2014-04-09 13:10 GMT+02:00 Stephan Eggermont <stephan(a)stack.nl>: > Your calculation seem to be off. > 32 * 86400 objects = 2.8 million objects.
