And that's where I disagree with the author of the refactoring site.
But that's one person's opinion. Other people who have written about
refactoring
Changing the name of a function which is externally available is
changing the behavior. It means changing every piece of code which
calls the function.
For instance, between Apache 1.x and 2.x, the Apache foundation changed
some of the function calls. This causes problems with any modules which
call those functions.
By your argument, ZEND should change the fopen() call to be file_open().
How much code would that affect?
Rather, they might change the code to make it more efficient and not
change the function name. This is refactoring.
But the author is correct - there is very little information available
on refactoring. In some ways the site is good. But in other ways it
contains incorrect information.
As to the Wikipedia page - I have no idea who wrote this page. Was it
the same person? Or someone else without a good idea about it? Anyone
can create a page there. I could create one which says the sun rises in
the west. Does this make it so?
