[Gluster-devel] New QUOTA translator (max size limit on posix xlator)

[Angel]

hi all

After playing a bit with the code to see my long time ago forgotten coding 
skills...

I have duplicate xlators/debug/trace into xlators/features/quota
Updated makefiles.am and configure.ac
Added getting option max-size from dict and storing in quota_private struct

No more funcionality at this point apart of funcs inherited from trace module...

Using tla636 as codebase

autogen.sh, configure and make were successfull without any errors

cp'ing  xlators/features/quota/src/quota.so on 
/usr/lib64/glusterfs/1.3.8tla636/xlator/features/quota.so

allows me live testing on my current 1.3.8tla636 installed package.


Still pour funcionality to make a patch but can send it if anyone interested :-)

PS: rpm generated from tla 1.3.6 places libs on lib64 on my machine (i386 
Pentium M 1700 centrino, Opensuse 10.3) this seems incorrect

That's enough for today, see you
