Crate a shared repository

  $ echo "[extensions]"      >> $HGRCPATH
  $ echo "share = "          >> $HGRCPATH

  $ cd $TESTTMP
  $ hg init repo1
  $ echo a > repo1/a
  $ hg -R repo1 commit -A -m'init'
  adding a

  $ hg share repo1 repo2
  updating working directory
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

And check that basic rhg commands work with sharing

  $ $NO_FALLBACK rhg files -R repo2
  repo2/a
  $ $NO_FALLBACK rhg -R repo2 cat -r 0 repo2/a
  a

Same with relative sharing

  $ hg share repo2 repo3 --relative
  updating working directory
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ $NO_FALLBACK rhg files -R repo3
  repo3/a
  $ $NO_FALLBACK rhg -R repo3 cat -r 0 repo3/a
  a

Same with share-safe

  $ echo "[format]"         >> $HGRCPATH
  $ echo "use-share-safe = True" >> $HGRCPATH

  $ cd $TESTTMP
  $ hg init repo4
  $ cd repo4
  $ echo a > a
  $ hg commit -A -m'init'
  adding a

  $ cd ..
  $ hg share repo4 repo5
  updating working directory
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

And check that basic rhg commands work with sharing

  $ cd repo5
  $ $NO_FALLBACK rhg files
  a
  $ $NO_FALLBACK rhg cat -r 0 a

The blackbox extension is supported

  $ touch .hgsub
  $ $NO_FALLBACK rhg files

The `:required` extension suboptions are correctly ignored

  $ rhg files
  a
  $ echo "*:required = yes" >> $HGRCPATH
  $ rhg files
