Setup extension:

  $ echo "[extensions]" >> $HGRCPATH

  $ echo "mq =" >> $HGRCPATH

  $ echo "[mq]" >> $HGRCPATH

  $ echo "git = keep" >> $HGRCPATH

Test merge with mq changeset as the second parent:

  $ hg init m

  $ cd m

  $ touch a b c

  $ hg add a

  $ hg commit -m a

  $ hg add b

  $ hg qnew -d "0 0" b

  $ hg update 0

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

  $ hg add c

  $ hg commit -m c

  created new head

  $ hg merge

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

  (branch merge, don't forget to commit)

  $ hg commit -m merge

  abort: cannot commit over an applied mq patch

  $ cd ..

Issue529: mq aborts when merging patch deleting files

  $ checkundo()

  > {

  >     if [ -f .hg/store/undo ]; then

  >         echo ".hg/store/undo still exists"

  >     fi

  > }

Commit two dummy files in "init" changeset:

  $ hg init t

  $ cd t

  $ echo a > a

  $ echo b > b

  $ hg ci -Am init

  adding a

  adding b

  $ hg tag -l init

Create a patch removing a:

  $ hg qnew rm_a

  $ hg rm a

  $ hg qrefresh -m "rm a"

Save the patch queue so we can merge it later:

  $ hg qsave -c -e

  copy $TESTTMP/t/.hg/patches to $TESTTMP/t/.hg/patches.1

  $ checkundo

Update b and commit in an "update" changeset:

  $ hg up -C init

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

  $ echo b >> b

  $ hg st

  M b

  $ hg ci -m update

  created new head

# Here, qpush used to abort with :

# The system cannot find the file specified => a

  $ hg manifest

  a

  b

  $ hg qpush -a -m

  merging with queue at: $TESTTMP/t/.hg/patches.1

  applying rm_a

  now at: rm_a

  $ checkundo

  $ hg manifest

  b

Ensure status is correct after merge:

  $ hg qpop -a

  popping rm_a

  popping .hg.patches.merge.marker

  patch queue now empty

  $ cd ..

Classic MQ merge sequence *with an explicit named queue*:

  $ hg init t2

  $ cd t2

  $ echo '[diff]' > .hg/hgrc

  $ echo 'nodates = 1' >> .hg/hgrc

  $ echo a > a

  $ hg ci -Am init

  adding a

  $ echo b > a

  $ hg ci -m changea

  $ hg up -C 0

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

  $ hg cp a aa

  $ echo c >> a

  $ hg qnew --git -f -e patcha

  $ echo d >> a

  $ hg qnew -d '0 0' -f -e patcha2

Create the reference queue:

  $ hg qsave -c -e -n refqueue

  copy $TESTTMP/t2/.hg/patches to $TESTTMP/t2/.hg/refqueue

  $ hg up -C 1

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

Merge:

  $ HGMERGE=internal:other hg qpush -a -m -n refqueue

  merging with queue at: $TESTTMP/t2/.hg/refqueue
