lazyparser speed ups -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 lazyparser speed ups When we do __contains__ on a map, we might as well load the whole index. Not doing this was slowing down finding new changesets quite by a factor of 20. When we do a full load, we also attempt to replace the revlog's index and nodemap with normal Python objects to avoid the lazymap overhead. manifest hash: 9b2b20aacc508f9027d115426c63a381d28e5485 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCreYIywK+sNU5EO8RAoNHAJ9+LmXqsTQb9Bh3mZHq0A0VfQOleQCffHmn jC/O0vnfx5FCRsX2bUFG794= =BDTz -----END PGP SIGNATURE-----
