I recently started to do some modifications on tor path selection by using stem, torflow/op-addon and txtorconn. but as long as i enable __LeaveStreamsUnattached option, tor will not function properly.

so i decided to hack the source for this feature i seek:

custom country for each position:

entry:{{entry country-code}}

middle:{{middle country-code}}

exit:{{country-code}}

i really appreciate you guys give me some hint, that which part of the source i must start to hack?

i have dived into circuitbuild.c and some other core/or modules but i am confused where to start.

thanks in advance.
