evolve: create resolved cset on successors of current parents
While resolving content-divergence, sometimes, the parent can be obsolete and
have a successor. We should consider the successors of the parents instead of
obsolete parents as that will do something like orphan+content-divergence
resolution both at the same time which is powerful and results in a single stack
while resolving content-divergence of stacks.
The test changes demonstrates that we can now successfully evolve a content
divergent stack.

\/

And A1-A2, B1-B2 and C1-C2 are content-divergent, and merging A1-A2 results in
conflicts.
Now if you resolve conflicts and continue resoling B1-B2, the conflicts of A1-A2
will still be there. We need somehow to understand the work we has done and not
create conflicts again.
To test the evolution functionality for now, we make sure conflicts does not
occur.

evolve: create a new commit instead of amending one of the divergents
This patch changes the behavior of evolve command while resolving
content-divergence to create a new commit instead of amending one of the
divergent ones.
In past, I have made this change, backed out this change and now today again I
am doing this change, so let's dive in some history.
Using cmdrewrite.amend() was never a good option as that requires hack to delete
the evolvestate and also gives us less control over things. We can't make the
commit on top of different parents as that of content-divergent ones. Due to all
these, I first made this change to create a new commit instead of amending one.
But, after few days, there was flakiness observed in the tests and turned out
that we need to do some dirstate dance as repo.dirstate.setparents() does not
always fix the dirstate. That flakiness was a blocker for progress at that time
and we decided to switch to amend back so that we can have things working with
some hacks and we can later fix the implementation part.
Now, yesterday while tackling resolving content-divergence of a stack which is
as follows:
C1 C2
| |
B1 B2
| |
A1 A2
\/
base
where, A1-A2, B1-B2, C1-C2 are content-divergent with each other. Now we can
resolve A1-A2 very well because they have the same parent and let's say that
resolution leads to A3.
Now, we want to resolve B1-B2 and make the new resolution commit on top of A3 so
that we can end up something like:
C3
|
B3
|
A3
|
base
however, amending one of the divergent changesets, it's not possible to create a
commit on a different parent like A3 here without some relocation. We should
prevent relocation as that may leads to some conflicts and should change the
parent before committing.
So, looking ahead, we can't move with using amend as still using that we will
need some relocation hacks making code ugly and prone to bad behaviors, bugs.
Let's change back to creating a new commit so that we can move forward in a good
way.
About repo.dirstate.setparents() not setting the dirstate, I have researched
yesterday night about how we can do that and found out that we can use
cmdrewrite._uncommitdirstate() here. Expect upcoming patches to improve the
documentation of that function.
There are lot of test changes because of change in hash but there is no behavior
change. The only behavior change is in test-evolve-abort-contentdiv.t which is
nice because creating a new commit helps us in stripping that while aborting.
We have a lot of testing of content-divergence and no behavior change gives
enough confidence for making this change.
I reviewed the patch carefully to make sure there is no behavior change and I
suggest reviewer to do the same.

evolve: always order the revs to be evolved
The current code only order the revs if we are resolving orphans and not in
other case. The ordering is important when we pass --all and tackle multiple
occurence of the same instability.
Let's order the revs for each instability. There are enough test coverage of
phase-divergence and content-divergence that I feel confident doing it because
none of the test changed.

evolve: improve error messages when conflicts occur
This patch improves the error messages when conflicts occur.
First, we drop the line 'evolution failed', that is not the best line we can
show and evolution didn't failed, it's just interrupted by the conflicts and
when user will run `hg evolve --continue`, things will be fine. I still remember
when I first saw 'evolution failed', I got a bit scare as am I in a recoverable
position or not. So let's drop this scary line.
Second, we replace the error messages to say `resolve conflicts and see
help-topic`. The help topic was added recently and documents all the three flags
very well. Addition of tests also showed that all the three flags works fine
with all the three instability type. So we should advertise them more.
Third, we now raise the error with our error message rather than raising
MergeFailure and having evolution related text in hint or stderr above. This
increase the focus on the error message we want to show.
After this patch, I think error messages by evolve in case of conflicts will be
same in every case.
