What's the difference between cascade="remove" and orphanRemoval=true in Doctrine 2

TLDR: The cascade={"remove"} is like a "software" onDelete="CASCADE", and will remove objects from the database only when an explicit call to $em->remove() occurs. Thus, it could result in more than one object being deleted. orphanRemoval can remove objects from the database even if there was no explicit call to ->remove().

I answered this question a few times to different people so I will try to sum things up in this Gist.

Let's take two entities A and B as an example. I will use a OneToOne relationship in this example but it works exactly the same with OneToMany relationships.

Video stabilization using VidStab and FFMPEG

** Step 1 **

Install ffmpeg with the vidstab plugin.

OSX: Install via Homebrew - brew install ffmpeg --with-libvidstab
Linux: download binaries here (vidstab included)
Windows: download binaries here (vidstab included)

How did you find these?

I used a service called Censys Search to find them. There's some queries you can do:

services.http.response.html_title: "cobalt"
- This one can find web instances. Does lead to false positives, since any title can contain "cobalt."
services.http.response.body_hash="sha1:bf53b9ab96065ed263df9ebcd2b3b0c4d88242b5"
- This one can find API instances. This is the hash of the response that all instances use.
You can probably also look for just port 9001/9000, but most of these ports are not default.

After I collected the list, I checked /api/serverInfo on the API instances to see if it has a url set. This can either be a subdomain or an IP. If it had a domain set, I tried to find the web instance by checking common subdomains (like co, cobalt, etc). If there were no connecting domains, I tried a look up the IP on SecurityTrails. Otherwise, it simply got listed as the IP.
