revlog: test more complex file pattern for revlog split

There have been a report of failure while splitting revlog. The file name
involved was important. The pattern involved here are not problematic, but it
help to setup the machinery to test multiple files, the actual fix and
problematic file will arrive in a later changeset.

test sparse

  $ hg init myrepo
  $ cd myrepo
  $ cat >> $HGRCPATH <<EOF

Import a rules file against a 'blank' sparse profile

  $ cat > $TESTTMP/rules_to_import <<EOF
  > [include]
  > *.py
  > EOF
  $ hg debugsparse --import-rules $TESTTMP/rules_to_import
  $ ls -A
  .hg

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

  $ ls -A

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

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

  $ hg debugsparse --enable-profile webpage.sparse
  $ hg debugsparse --include *.py
  $ cat > $TESTTMP/rules_to_import <<EOF
  > %include base.sparse
  > [include]
  > *.html

  $ hg debugsparse --import-rules $TESTTMP/rules_to_import
  $ ls -A

  base.sparse
  index.html
  readme.txt
  webpage.sparse
  $ cat .hg/sparse
  %include webpage.sparse
  [include]
  *.py
  *.txt
  [exclude]
  *.py

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

Same tests, with -Tjson enabled to output summaries

  $ rm .hg/sparse

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

  $ cat > $TESTTMP/trap_sparse_refresh.py <<EOF
  > from mercurial import error, sparse
  > def extsetup(ui):
  >     def abort_refresh(*args, **kwargs):
  >         raise error.Abort(b'sparse._refresh called!')
  >     sparse.refreshwdir = abort_refresh
  > EOF
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > trap_sparse_refresh=$TESTTMP/trap_sparse_refresh.py
  > EOF
  $ cat > $TESTTMP/rules_to_import <<EOF
  > [include]
  > *.py
  > EOF
  $ hg debugsparse --import-rules $TESTTMP/rules_to_import

If an exception is raised during refresh, restore the existing rules again.

  $ cat > $TESTTMP/rules_to_import <<EOF
  > [exclude]
  > *.html
  > EOF
  $ hg debugsparse --import-rules $TESTTMP/rules_to_import
  abort: sparse._refresh called!

  $ cat .hg/sparse
  %include webpage.sparse
