bundlespec: fix the "streamv2" and "streamv3-exp" variant In c4aab3661f25, we broken this feature by adding unicode instead of bytes to the dictionary. On the other hand, this feature was never tested, so augment the tests to tests this.

test sparse

  $ hg init myrepo
  $ cd myrepo

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

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
  > *.txt
  > [exclude]
  > *.py
  > EOF
  $ hg debugsparse --import-rules $TESTTMP/rules_to_import
  $ ls -A
  .hg
  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

  $ cat > $TESTTMP/rules_to_import <<EOF

  $ hg debugsparse --import-rules $TESTTMP/rules_to_import -Tjson

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

  $ cat > $TESTTMP/rules_to_import <<EOF

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
