Subject: kcc/graph: add __hash__ to InternalEdge for py3
X-Git-Tag: ldb-1.4.0~583
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6eb3391cc251cac484ce34397c18373331ffcb78;p=thirdparty%2Fsamba.git

kcc/graph: add __hash__ to InternalEdge for py3

In py3, if a class defines `__eq__()` but not `__hash__()`, its instances will
not be usable as items in hashable collections, e.g.: set.

Add `__hash__()` to InternalEdge, so it can be added to a set in py3.
