Do we need to drain a buffered channel after closing it?

[Shubha_DA (Shubha Dhananjaya Achar)]

I have been working with buffered channels. I have stumbled upon a scenario where buffered channel will be closed and the receiver of the channel terminates before consuming all the elements in the buffer. So my question is will there be any issue regarding Garbage Collection of channel which eventually leads to memory or resource leaks because of the left out items in the buffer? or any other concerns that I must be aware of?

The whole process should be ended in the consumer, when it gets all the data from the producer. So maybe you can add a “signal” channel to let consumer know that the producer is done with its work.

What happens when a channel goes out of scope

The data in the channel do not implicitly reference the channel, so the channel should be collected independent of its contents, unless, of course the data are structs that do reference the channel. In that case, mutual references are not a problem for garbage collection. However, the data cannot be collected if an uncollected channel still references them.
