I would appreciate if anyone on the list can clarify if the following is a bug
or expected behaviour. I hope the diagrams will come out OK when this is posted.
I'm developing some features in 'x' branch, with a plan to merge periodically
in another branch 'y', when stable. So I have added some files in 'x' to
checkpoint (0), merged to 'y'.
X Y
| |
(0) ----M(0)
Next, I've added several more files in a check-in (1) to a branch 'y', but
realised they had issues. I've edited that check-in (1) to be a start on new
'mistake' branch, and modified the files in subsequent check-in (2) there. I
merged 'mistake' back to my 'y', all good - commit to (3) on 'y'.
X Y
| |
(0) ----M(0) mistake
| (1)
| |
(3)M----(2)
Then I realised changes in (3) shouldn't be in 'y', but in 'x'. No probs -
I'll just do a baseline merge and put them there, I thought.
1. This is the first surprise. When doing 'f merge --baseline (1)' in branch
'x' checkout, I get the message 'no unmerged forks of branch "x"'. What does
this mean? I thought it would have pulled (1), (2)/(3) into branch 'x'.
So instead, I did two cherry-pick merges, one on top of the other: from (1),
then (2) to 'x' - (3) was a no-op - committed, all good. Or so I thought.
X Y
| |
(0) ----M(0) mistake
| | (1)-----|
| | | |
| (3)M----(2) |
| | |
(12)CM----------|-------|
2. Later, I had some more changes committed in 'x' (4) and tried to merge them
to 'y'. Another surprise: when doing 'f merge x' in branch 'y' checkout, I get
'no common ancestor' warnings on *all* files that I have added previously in
both (0) *and* (1). Why is this?
X Y
| |
(0) ----M(0) mistake
| | (1)-----|
| | | |
| (3)M----(2) |
| | |
(1,2)CM---------|-------|
| |
(4)---M(warnings)
So I lost modifications on some of those files that were committed in (4).
However, the *new* file I committed in (4) was successfully 'added_by_merge'.
This does not make sense to me. I thought that files that have been merged into
'y'(3), and then later cherry-pick merged to 'x'(1,2), would have had the
common ancestors in (1) and (2). I also don't understand why am I receiving
such warnings for files that have been committed in 'X' in (0) and successfully
merged to 'Y' at the beginning.
Is this a bug?
