I had a complete build (details probably don't matter) using

I made a single line change in the recipe (removing a line from
the do_install step). When I then rebuilt the recipe, to my
surprise, there were more than 450 tasks (73 unique recipes)
executed :-(
How does this make any sense? unless the build system cares
that I changed the branch?
n.b. I'm happy to provide more details if necessary. Also, I
did this twice in two different build trees and saw the same
strangeness.
I think so additional info might be needed here, I am guessing that you are
changing pygtk and somehow that is changing some dependency, you might try
using bitbake-diffsigs
between the 2 versions.
I think I know what triggered this - a recent change in bitbake.conf
redefined BUILD_CPP (and others). I had merged this change some six
hours before my strange build and had been building many other recipes
(also python with a similar set of dependencies) a number of times
before I touched the python-pygtk recipe. Some dependency in that
recipe set off the rebuild storm that my other recipes had not.
So the large number of recipe rebuilds was [probably] warranted, but
very unexpected given what I had been doing just prior.
Sorry for the noise. Next time I'll try and remember bitbake-diffsigs
and figure things out on my own.
