examples/unixfs-file-cid: io.Copy is never completed when read a single char-filled contents

[tmrkw1497]

I modified unixfs-file-cid example program so that it could distribute files instead of strings. And, I try to distribute any files with a modified example program. When I try to do it with the same char-filled file (e.g. 0x00, 0x01 filled), the sample receiver program had never completed. In the same program, I can distribute random chars-filled files.

Expected Behavior

I can download and display the same char-filled file.

Current Behabior

io.Copy is never complete. https://github.com/ipfs/boxo/blob/b96767cc0971ca279feb36e7844e527a774309ab/examples/unixfs-file-cid/main.go#L225

steps to reproduce

$ git clone https://github.com/ipfs/boxo.git
$ cd boxo/examples
$ vim unixfs-file-cid/main.go # edit code
$ go run unixfs-file-cid/main.go

other terminal

$ cd boxo/examples
$ go run unixfs-file-cid/main.go -d "peer address"

I modified it. https://github.com/ipfs/boxo/blob/main/examples/unixfs-file-cid/main.go#L145-L149

fileReader,err:= os.Open("file path")
if err!=nil{
return cid.Undef, nil, err
}

cid should be changed. https://github.com/ipfs/boxo/blob/b96767cc0971ca279feb36e7844e527a774309ab/examples/unixfs-file-cid/main.go#L129

I made file this command (the file should be of some size)

$ dd if=/dev/zero of="file path" bs=1G count=1

Environment

• go version go1.19.12 linux/amd64
• ubuntu 22.10
• use boxo which was pulled from master branch (v.0.11.0)
