If I have something like this:
requests := make(chan *RequestStruct, 1000 * 1000)
responses := make(chan *ResponseStruct, 1000 * 1000)
If the all requests and responses already dequeued/consumed, those pointers that previously was there would someday will be garbage collected right? (or it won't because nobody ever set it to nil on the channel?)
Channels are implemented in runtime/chan.go. Reading from a buffered channel is implemented by the function chanrecv, which does the following:
qp := chanbuf(c, c.recvx)
typedmemmove(c.elemtype, ep, qp)
typedmemclr(c.elemtype, qp)
The element that is stored in the channel is cleared by the typedmemclr, and will therefore not prevent the pointed-at element from being garbage-collected.
