Hi all. I've been trying to fix a rainbow texture corruption bug the past few days with little success. Using UDP, its ok. Using http texture fetch, it get corrupted.
I've managed to figure what is causing the texture to get corrupted after downloading and displaying it. What happens is that on textures that have the same file size for discard level 1 and 0, the data size sent to the decoder is incorrect. See http://pastebin.com/Kc9x5BNS for the detailed debug output for that texture. I've managed to trace back to the function that is returning the incorrect data recieved in lltextruefetch.cpp, "mFormattedImage->getDataSize()". That function is used to calculate the amount of data to memcopy and to send to the decoder. "mFormattedImage->getDataSize()" goes back to llimage.cpp and from there who knows, i've can't trace it back anymore. Somewhere between libcurl returning data and lltextruefetch, the amount of data recieved is getting corrupted somewhere. If someone knows of this bug or can point me in the right direction of how the size data from libcurl gets to lltexturefetch.cpp I would be grateful. --Techwolf Lupindo _______________________________________________ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/OpenSource-Dev Please read the policies before posting to keep unmoderated posting privileges
