py3: paper over differences in future exception handling

It looks like Python 3's futures library lacks set_exception_info
entirely. We'll just give up and use set_exception in that case.

# no-check-commit because the underbar naming is just saner here

Differential Revision: https://phab.mercurial-scm.org/D3336

test that a commit clears the merge state.

  $ hg init repo
  $ cd repo

  $ echo foo > file1
  $ echo foo > file2
  $ hg commit -Am 'add files'
  adding file1
  adding file2

  $ echo bar >> file1
  $ echo bar >> file2
  $ hg commit -Am 'append bar to files'

create a second head with conflicting edits

  $ hg up -C 0
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo baz >> file1
  $ echo baz >> file2
  $ hg commit -Am 'append baz to files'
  created new head

create a third head with no conflicting edits
  $ hg up -qC 0
  $ echo foo > file3
  $ hg commit -Am 'add non-conflicting file'
  adding file3
  created new head

failing merge

  $ hg up -qC 2
  $ hg merge --tool=internal:fail 1
  0 files updated, 0 files merged, 0 files removed, 2 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon
  [1]

resolve -l should contain unresolved entries

  $ hg resolve -l
  U file1
  U file2

  $ hg resolve -l --no-status
  file1
  file2

resolving an unknown path should emit a warning, but not for -l

  $ hg resolve -m does-not-exist
  arguments do not match paths that need resolving
  $ hg resolve -l does-not-exist

tell users how they could have used resolve

  $ mkdir nested
  $ cd nested
  $ hg resolve -m file1
  arguments do not match paths that need resolving
  (try: hg resolve -m path:file1)
  $ hg resolve -m file1 filez
  arguments do not match paths that need resolving
  (try: hg resolve -m path:file1 path:filez)
  $ hg resolve -m path:file1 path:filez
  $ hg resolve -l
  R file1
  U file2
  $ hg resolve -m filez file2
  arguments do not match paths that need resolving
  (try: hg resolve -m path:filez path:file2)
  $ hg resolve -m path:filez path:file2
  (no more unresolved files)
  $ hg resolve -l
  R file1
  R file2

cleanup
  $ hg resolve -u
  $ cd ..
  $ rmdir nested
