Graft from behind a move or rename
==================================
NOTE: This is affected by issue5343, and will need updating when it's fixed
Possible cases during a regular graft (when ca is between cta and c2):
name | c1<-cta | cta<->ca | ca->c2
A.0 | | |
A.1 | X | |
A.2 | | X |
A.3 | | | X
A.4 | X | X |
A.5 | X | | X
A.6 | | X | X
A.7 | X | X | X
A.0 is trivial, and doesn't need copy tracking.
For A.1, a forward rename is recorded in the c1 pass, to be followed later.
In A.2, the rename is recorded in the c2 pass and followed backwards.
A.3 is recorded in the c2 pass as a forward rename to be duplicated on target.
In A.4, both passes of checkcopies record incomplete renames, which are
then joined in mergecopies to record a rename to be followed.
In A.5 and A.7, the c1 pass records an incomplete rename, while the c2 pass
records an incomplete divergence. The incomplete rename is then joined to the
appropriate side of the incomplete divergence, and the result is recorded as a
divergence. The code doesn't distinguish at all between these two cases, since
the end result of them is the same: an incomplete divergence joined with an
incomplete rename into a divergence.
Finally, A.6 records a divergence entirely in the c2 pass.
A.4 has a degenerate case a<-b<-a->a, where checkcopies isn't needed at all.
A.5 has a special case a<-b<-b->a, which is treated like a<-b->a in a merge.
A.6 has a special case a<-a<-b->a. Here, checkcopies will find a spurious
incomplete divergence, which is in fact complete. This is handled later in
mergecopies.
A.7 has 4 special cases: a<-b<-a->b (the "ping-pong" case), a<-b<-c->b,
a<-b<-a->c and a<-b<-c->a. Of these, only the "ping-pong" case is interesting,
the others are fairly trivial (a<-b<-c->b and a<-b<-a->c proceed like the base
case, a<-b<-c->a is treated the same as a<-b<-b->a).
f5a therefore tests the "ping-pong" rename case, where a file is renamed to the
same name on both branches, then the rename is backed out on one branch, and
the backout is grafted to the other branch. This creates a challenging rename
sequence of a<-b<-a->b in the graft target, topological CA, graft CA and graft
source, respectively. Since rename detection will run on the c1 side for such a
sequence (as for technical reasons, we split the c1 and c2 sides not at the
graft CA, but rather at the topological CA), it will pick up a false rename,
and cause a spurious merge conflict. This false rename is always exactly the
reverse of the true rename that would be detected on the c2 side, so we can
correct for it by detecting this condition and reversing as necessary.
First, set up the repository with commits to be grafted
$ hg init ../graftmove
$ cd ../graftmove
$ echo c1a > f1a
$ echo c2a > f2a
$ echo c3a > f3a
$ echo c4a > f4a
$ echo c5a > f5a
$ hg ci -qAm A0
$ hg mv f1a f1b
$ hg mv f3a f3b
$ hg mv f5a f5b
$ hg ci -qAm B0
$ echo c1c > f1b
$ hg mv f2a f2c
$ hg mv f5b f5a
$ echo c5c > f5a
$ hg ci -qAm C0
$ hg mv f3b f3d
$ echo c4d > f4a
$ hg ci -qAm D0
$ hg log -G
