Check we preserve the author properly

-------------------------------------

Testing issue6113 to make sure that content-divergence resolution don't

replace initial author with the user running the resolution command:

  $ hg init userfoo

  $ cd userfoo

  $ unset HGUSER

  $ echo "[ui]" >> ./.hg/hgrc

  $ echo "username = foo <foo@test.com>" >> ./.hg/hgrc

  $ for ch in a b c; do

  > echo $ch > $ch;

  > hg add $ch;

  > hg ci -m "added "$ch;

  > done;

  $ cd ..

  $ hg init userbar

  $ cd userbar

  $ unset HGUSER

  $ echo "[ui]" >> ./.hg/hgrc

  $ echo "username = bar <bar@test.com>" >> ./.hg/hgrc

  $ hg pull ./../userfoo -q

  $ cd ../userfoo

  $ hg up -r "desc('added b')"

  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ echo c > c

  $ echo e > e

  $ hg add c e

  $ hg ci -m "added c e"

  created new head

  $ hg up -r "desc('added b')"

  0 files updated, 0 files merged, 2 files removed, 0 files unresolved

  $ echo cc > c

  $ hg add c

  $ hg ci -m "added c"

  created new head

  $ hg prune -r "min(desc('added c'))" -s "desc('added c e')"

  1 changesets pruned

  $ hg prune -r "min(desc('added c'))" -s "max(desc('added c'))" --hidden

  1 changesets pruned

  2 new content-divergent changesets

  $ hg glog

  $ cd ../userbar

  $ hg pull ./../userfoo -q

  $ hg evolve --content-divergent --any

  merge:[3] added c e

  base: [2] added c

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Make sure resultant cset don't replace the initial user with user running the command:

  $ hg log -r tip

  changeset:   5:8cabe7248d20

  tag:         tip

  parent:      1:1740ad2a1eda

  date:        Thu Jan 01 00:00:00 1970 +0000

  summary:     added c e

  $ cd ..

Testing the three way merge logic for user of content divergent changesets

--------------------------------------------------------------------------

  $ hg init mergeusers

  $ cd mergeusers

  $ for ch in a b c; do

  > touch $ch

  > hg add $ch

  > hg ci -m "added "$ch

  > done;

  $ hg amend -m "updated c"

  $ hg up -r 'desc("added c")' --hidden -q

  updated to hidden changeset 2b3c31fe982d

  (hidden revision '2b3c31fe982d' was rewritten as: 464e35020fd0)

  working directory parent is obsolete! (2b3c31fe982d)

  $ echo coco > c

1) when one user is different wrt base

--------------------------------------

Insert a diverging author name:

  $ hg amend -u 'foouser'

  2 new content-divergent changesets

Run automatic evolution:

  $ hg evolve --content-divergent

  merge:[3] updated c

  with: [4] added c

  base: [2] added c

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  working directory is now at 2300a271820b

  $ hg log -r tip | grep "^user"

  user:        foouser

  $ hg strip . -q --config extensions.strip=

  2 new content-divergent changesets

2) when both the user are different wrt base

--------------------------------------------

  $ hg up -r 'max(desc("updated c"))'

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg amend -u 'baruser'

Run automatic evolution:

  $ hg evolve --content-divergent

  merge:[4] added c

  with: [5] updated c

  base: [2] added c

  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  working directory is now at 3d7ae55fbfe4

  $ hg log -r tip | grep "^user"

  user:        baruser, foouser

  $ cd ..

Test the content-divergence resolution involving date update

------------------------------------------------------------

  $ hg init divergingdate

  $ cd divergingdate

  $ unset HGUSER

  $ echo "[ui]" >> ./.hg/hgrc

  $ echo "username = test" >> ./.hg/hgrc

  $ echo hi > r0

  $ hg ci -qAm 'add r0'

  $ echo hi > foo.txt

  $ hg ci -qAm 'add foo.txt'

  $ hg metaedit -r . -d '0 2'

  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

date: updated on both side to the same value

  $ echo hi > bar.txt

  $ hg add -q bar.txt

  $ hg amend -q

  $ hg metaedit -r 1 -d '0 1' --hidden
