Import a rules file against a 'blank' sparse profile

  $ cat > $HGTMP/rules_to_import <<EOF
  > [include]
  > *.py
  > EOF
  $ hg sparse --import-rules $HGTMP/rules_to_import
  $ ls
  data.py

  $ hg sparse --reset
  $ rm .hg/sparse

  $ cat > $HGTMP/rules_to_import <<EOF

  > EOF
  $ hg sparse --import-rules $HGTMP/rules_to_import
  $ ls
  base.sparse
  data.py
  webpage.sparse

  $ hg sparse --reset
  $ rm .hg/sparse

Start against an existing profile; rules *already active* should be ignored

  $ hg sparse --enable-profile webpage.sparse
  $ hg sparse --include *.py
  $ cat > $HGTMP/rules_to_import <<EOF
  > %include base.sparse
  > [include]
  > *.html
  > *.txt
  > [exclude]
  > *.py
  > EOF
  $ hg sparse --import-rules $HGTMP/rules_to_import
  $ ls
  base.sparse
  index.html
  readme.txt
  webpage.sparse
  $ cat .hg/sparse
  %include webpage.sparse
  [include]
  *.py
  *.txt
  [exclude]
  *.py

  $ hg sparse --reset
  $ rm .hg/sparse

Same tests, with -Tjson enabled to output summaries

  $ cat > $HGTMP/rules_to_import <<EOF

If importing results in no new rules being added, no refresh should take place!

  $ cat > $HGTMP/trap_sparse_refresh.py <<EOF

  >         if not loaded:
  >             return
  >         sparse = extensions.find('sparse')
  >         sparse._refresh = abort_refresh
  >     extensions.afterloaded('sparse', sparseloaded)
