I noticed a small spot of water on the basement floor this morning and
looked up to see a tiny pinhole leak in the copper pipe (tube?) directly
above. It leaks a droplet every few hours, so it's something that a rag is
absorbing for now.
What's the best way to repair it? It's near a joist hanger strap and I
suspect the damage was causing by an errant hammer blow and not inherent
vice. But that's just a guess. For all I know, pinholes are about to
emerge throughout the house.
This is the first pinhole leak I've ever seen in the house. Every other
leak (and in a 70 year old house there have been a few) has been at
copper/iron union, a coupling or a valve.

Patch it and worry about it later or cut a section out and give it a
good looking over to see if it's something to worry about and maybe time
to do some real serious plumbing.
Some water chemistry,

You can do some testing and determine if your water is corrosive or
scaling.
