merge: return an attrs class from update() and applyupdates() Previously, we returned a tuple containing counts. The result of an update is kind of complex and the use of tuples with nameless fields made the code a bit harder to read and constrained future expansion of the return value. Let's invent an attrs-defined class for representing the result of an update operation. We provide __getitem__ and __len__ implementations for backwards compatibility as a container type to minimize code churn. In (at least) Python 2, the % operator seems to insist on using tuples. So we had to update a consumer using the % operator. .. api:: merge.update() and merge.applyupdates() now return a class with named attributes instead of a tuple. Switch consumers to access elements by name instead of by offset. Differential Revision: https://phab.mercurial-scm.org/D2692
