The 3rd party code in question here is only for testing purposes. It is
only enabled with a configure flag, so, outside of development, will not
usually be used.
On the general principle of whether to include 3rd party code, I'm not sure
I agree with your stance. For instance, we include the Nagios::Plugins perl
modules (and dependencies). This is to simplify installation for our users.
However, there is a configure option to not include the perl modules, so
you can add the appropriate dependencies at the packaging layer instead.
A more entrenched example would be GNU lib - we embed their code (at their
recommendation). Theoretically, a security exposure could be found there.
But we have a very simple process to update their software and cut a new
package. There's no way I would want this project, or any others that use
gnulib, to have to recode all the functionality they provide.
I can't guarantee that we will not include 3rd party software in future. We
have to make a judgement on whether a 3rd party piece of code will provide
us features or cross platform capabilities we need without re-inventing the
wheel. That's a compromise we have to make. However, when possible, we will
allow configure options to disable 3rd party code.
