IIUC, the ConnectedLoopFinder::visit() function is the core function
which creates the dependency order. What I don't get is this: The
function starts with:
if (!db.packages[nodeToVisit]->installed)
/* Can't visit this node, and it is not less than any visted node */
return db.packages.size() + 1;
So, it skips packages which are not installed? What about packages
which are about to be installed the first time? Isn't their "installed"
packageversion NULL and only "desired" is a vaild version?
And then, assuming a package is about to be uninstalled. Doesn't that
package have a "desired" of NULL? And shouldn't such a package be
skipped in the dependency tracking?
I don't see where "installed" is set to the "desired" packageversion
before the dependency tracking is called. Can anybody help me to
understand this?
