test sparse

  $ hg init myrepo
  $ cd myrepo
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > sparse=
  > purge=

Clear rules when there are includes

  $ hg debugsparse --include *.py
  $ ls
  data.py
  $ hg debugsparse --clear-rules
  $ ls
  base.sparse
  data.py
  index.html
  readme.txt
  webpage.sparse

Clear rules when there are excludes

  $ hg debugsparse --exclude *.sparse
  $ ls
  data.py
  index.html
  readme.txt
  $ hg debugsparse --clear-rules
  $ ls
  base.sparse
  data.py
  index.html
  readme.txt
  webpage.sparse

Clearing rules should not alter profiles

  $ hg debugsparse --enable-profile webpage.sparse
  $ ls
  base.sparse
  index.html
  webpage.sparse
  $ hg debugsparse --include *.py
  $ ls
  base.sparse
  data.py
  index.html
  webpage.sparse
  $ hg debugsparse --clear-rules
  $ ls
  base.sparse
  index.html
  webpage.sparse
