tests: back out accidentally queued changeset 0627cd03b1e9
I accidentally queued other people's patches on top of my own and
pushed mine along with theirs.
#testcases filelog compatibility sidedata
=====================================================
Test Copy tracing for chain of copies involving merge
=====================================================
This test files covers copies/rename case for a chains of commit where merges
are involved. It cheks we do not have unwanted update of behavior and that the
different options to retrieve copies behave correctly.
Setup
=====
use git diff to see rename
$ cat << EOF >> $HGRCPATH
> [diff]
> git=yes
> [ui]
> logtemplate={rev} {desc}\n
> EOF
#if compatibility
$ cat >> $HGRCPATH << EOF
> [experimental]
> copies.read-from = compatibility
> EOF
#endif
#if sidedata
$ cat >> $HGRCPATH << EOF
> [format]
> exp-use-side-data = yes
> exp-use-copies-side-data-changeset = yes
> EOF
#endif

Merge:

- one overwriting that file with a rename (from h to i, to d)
This case is similar to BF/FB, but an actual merge happens, so both side of the
history are relevant.
Note:
| In this case, the merge get conflicting information since on one side we have
| "a -> c -> d". and one the other one we have "h -> i -> d".
|
| The current code arbitrarily pick one side

Comparing with merging with a deletion (and keeping the file)
-------------------------------------------------------------
Merge:
- one removing a file (d)
- one updating that file
- the merge keep the modified version of the file (canceling the delete)
In this case, the file keep on living after the merge. So we should not drop its
copy tracing chain.
$ hg up 'desc("c-1")'
1 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg merge 'desc("g-1")'
file 'd' was deleted in local [working copy] but was modified in other [merge rev].
You can use (c)hanged version, leave (d)eleted, or leave (u)nresolved.
What do you want to do? u
0 files updated, 0 files merged, 0 files removed, 1 files unresolved
use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon

Comparing with merge restoring an untouched deleted file
--------------------------------------------------------
Merge:
- one removing a file (d)
- one leaving the file untouched
- the merge actively restore the file to the same content.
In this case, the file keep on living after the merge. So we should not drop its
copy tracing chain.
