rpms: add chg I'm not sure if there's a reason chg is not added by default. If not, I would like to propose adding in this patch. Differential Revision: https://phab.mercurial-scm.org/D220

tests: demonstrate crash when trying to rebase merge without its parents As the test case shows, when "hg rebase -d G -r 'B + D + F'" is run on the following graph, we crash with traceback. It's reasonable to fail because we can not easily produce a correct rebased F. The problem is what diff to apply to either the rebased B or the rebased D. We could potentially produce the result by e.g. applying the (F-D) diff to the rebased B and then applying the reverse (E-D) diff on top, but that could result in merge conflicts in each of those steps, which we don't have a way of dealing with. So for now, let's just add a test case to demonstrate that we crash (i.e. the AssertionError is clearly incorrect since the user can run into it).

tests: demonstrate broken rebase of merge with p1's successor in dest The fix in 8ede973597fd (rebase: handle successor targets (issue5198), 2016-04-11) only fixed the case where p2's successor was in the destination, and only when the successor was exactly the destination (i.e. not when the successor was an ancestor of it). This patch adds a test case for when p1's successor is in the destination. It adds another one for when the successor is an ancestor of the destination. To do that simply, it also rewrites the test case using drawdag. Differential Revision: https://phab.mercurial-scm.org/D211
