Increase likelihood of generating any transaction data

[remoterami]

When generating random transactions with livefuzzer spam, I'm having issues generating random transaction data. After changing some logic to skip all the rpc interactions and just let it generate code, it takes multiple minutes to find anything other than 0 bytes of data. I don't think this is intended.. But I could also be missing something of course.

I don't think I understand the issue completely. livefuzzer spam will try to fund ~100 addresses from a faucet in order to send transactions from there. Afterwards transactions will be send by these addresses with fuzzed tx data.

How are you constructing your filler object?

I only ran a quick check to make sure everything works and it kinda looks okay to me

func TestRandomCode(t *testing.T) {
	for i := 0; i < 10; i++ {
		data := make([]byte, 64)
		rand.Read(data)
		f := filler.NewFiller(data)
		fmt.Println(RandomCode(f))
	}
	panic("asdf")
}

Ahh nvm I found the bug, the mutateBytes will not prefill the array, so it is almost completely empty. Will fix, thanks!

Thanks for reporting!

Thanks for fixing 👍
Just fyi, looking at it it should be the same for blobs

Thanks, I completely rewrote that part in order to get rid of the code duplication: #37
