treemanifest: make diff() faster Containment checking is slower in treemanifest than it is in manifestdict, making the current diff algorithm O(n log n). By traversing both treemanifests in parallel, we can make it O(n). More importantly, once we start lazily loading submanifests, we will be able to easily skip entire submanifest if they have the same nodeid.

#require test-repo

This code uses the ast module, which was new in 2.6, so we'll skip
this test on anything earlier.
  $ $PYTHON -c 'import sys ; assert sys.version_info >= (2, 6)' || exit 80

  $ import_checker="$TESTDIR"/../contrib/import-checker.py

Run the doctests from the import checker, and make sure
it's working correctly.
  $ TERM=dumb
  $ export TERM
  $ python -m doctest $import_checker

  $ cd "$TESTDIR"/..

There are a handful of cases here that require renaming a module so it
doesn't overlap with a stdlib module name. There are also some cycles
here that we should still endeavor to fix, and some cycles will be
hidden by deduplication algorithm in the cycle detector, so fixing
these may expose other cycles.
