From reading the code things look much much better, I will check & test with more detail later on the week.

On the mean time you can work on this:

• Looks like in pgtap/topology/nodeNetwork.test.sql you added has the steps to reproduce the problem mentioned on pgr_nodeNetwork issues #1336 and tested them. I prefer that you create a test file named issue-1336.sql where to put those new tests and remove those new tests from pgtap/topology/nodeNetwork.test.sql
• Please also make a commit where you add your name here
  and here

If possible this:

• you can add a tests files issue-1074.sql and issue-1009.sql that make a simple test over those issues that you are fixing. (trying to the best of your ability to use the issue openers/comments information)

The way I will test this is:

1. I will use your test files with current code and I am expecting to get pgtap fails
2. Then I will use your test files with the changes you made I am expecting to get pgtap successes

With (1) I see that is an appropriate test to catch the problem
With (2) I see that the problem is fixed

It should be ok now, I let you check.
