merge: store ACTION_KEEP_ABSENT when we are keeping the file absent locally
If a file is not present on the local side, and it's unchanged between other
merge parent and ancestor, we don't use any action, neither we had a if-else
branch for that condition. This leads to bid-merge missing that there is a
such action possible which can be performed.
As test changes demonstrate, we now choose the locally deleted side instead
of choosing the remote one consistently. This is also wrong behavior which is
resulted because of missing possible action. It will be fixed in next patch.
This whole logic is not acurrate as we should prompt user on what to do
when this kind of criss-cross merge is in play.

This test test the low-level definition of stack, agnostic from all formatting

marked working directory as branch other
(branches are permanent and global, did you want a bookmark?)

Check that stack doesn't include public changesets
--------------------------------------------------
$ hg up other
0 files updated, 0 files merged, 4 files removed, 0 files unresolved
$ hg log -G -r "stack()"
@ 1 other draft c_b
|
o 0 other draft c_a
$ hg phase --public 'branch("other")'
$ hg log -G -r "stack()"
$ hg up foo
4 files updated, 0 files merged, 0 files removed, 0 files unresolved
Simple test
-----------
'stack()' list all changeset in the branch
$ hg branch
foo
$ hg log -G -r "stack()"
@ 5 foo draft c_f
|
o 4 foo draft c_e
|
o 3 foo draft c_d

Case with some of the branch unstable
------------------------------------
$ hg up 3

$ echo bbb > ddd
$ hg commit --amend
2 new orphan changesets
$ hg log -G

Case with multiple topological heads
------------------------------------
Make things linear again
$ hg rebase -s 'desc(c_e)' -d 'desc(c_d) - obsolete()'
rebasing 4:4f2a69f6d380 "c_e"
rebasing 5:913c298d8b0a "c_f"

Create the second branch
$ hg up 'desc(c_d)'
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo aaa > ggg
$ hg add ggg
$ hg commit -m c_g
created new head
$ echo aaa > hhh

Test output
$ hg log -G -r "stack(10)"

Check the stack order
$ hg log -r "first(stack())"
9 foo draft c_g
$ hg log -r "first(stack(10))"
9 foo draft c_g
$ hg log -r "first(stack(8))"
7 foo draft c_e
$ hg log -r "first(stack(head()))"
7 foo draft c_e
Case with multiple heads with unstability involved
--------------------------------------------------
We amend the message to make sure the display base pick the right changeset
$ hg up 'desc(c_d)'
0 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ echo ccc > ddd
$ hg commit --amend -m 'c_D'
4 new orphan changesets
$ hg rebase -d . -s 'desc(c_g)'
rebasing 9:2ebb6e48ab8a "c_g"
rebasing 10:634f38e27a1d "c_h"
$ hg log -G
o 13 foo draft c_h
|
o 12 foo draft c_g
|
@ 11 foo draft c_D
|
| * 8 foo draft c_f
| |
| * 7 foo draft c_e
| |
| x 6 foo draft c_d
|/
o 2 foo draft c_c
|
o 1 other public c_b
|
o 0 other public c_a
We should improve stack definition to also show 12 and 13 here
$ hg log -G -r "stack()"
@ 11 foo draft c_D
