Contact
I can usually be found on IRC on #brlcad - freenode, I have various nicknames, depending on availablity : andrei, andrei_, andrei__. The quickest way to reach me on e-mail is the address: popescu.andrei1991@gmail.com - I read emails on this several times a day. My github account is : https://github.com/pandrei
I will use this page to keep track of my progress on a daily basis.
Project Summary
Firstly, here can be found my official proposal. https://google-melange.appspot.com/gsoc/proposal/review/google/gsoc2012/popescuandrei/4002
The purpose of a package managing library ( or tool) is to pass around packages containing data from brlcad tools. The packages are sent via TCP and as a result are using TCP header. TCP -- http://en.wikipedia.org/wiki/Transmission_Control_Protocol
My current knowledge is that the TCP Payload[1] has a size of 64kb, at least in the linux kernel. There has been a reported incident where libpkg fails to send 24k+ packages. [1] Payload - TCP field containinig effective data (user data, for example).
I believe this is the reported incident : http://permalink.gmane.org/gmane.comp.cad.brlcad.devel/959.
Tpkg will be used for testing the package issue. I am currently researching dstat and ifstat, found via apt-cache search ifstat dstat - versatile resource statistics tool ifstat - InterFace STATistics Monitoring
The curent state of brlcad libpkg is a basic client-server protocol.
GsoC 2012 progress
So far I have managed to compile and install brl-cad on a 32-bit Archlinux. I am focusing on the tpkg command to see what exactly happens and properly submitting the global removal patch.
