This commit contains the entire btcdb repository along with several
changes needed to move all of the files into the database directory in
order to prepare it for merging. This does NOT update btcd or any of the
other packages to use the new location as that will be done separately.
- All import paths in the old btcdb test files have been changed to the
new location
- All references to btcdb as the package name have been chagned to
database
- The coveralls badge has been removed since it unfortunately doesn't
support coverage of sub-packages
This is ongoing work toward #214.
The specific parameters required by a backend is better left up to the
backend itself. For example memdb has no need for a database path, while
ldb does. This commit modifies the OpenDB and CreateDB functions to take
a arbitrary arguments which are passed along to the driver. The driver is
expected to verify the correct type and number of arguments and error
accordingly.
The existing backends have been updated accordingly.
The idea here is that interface_test.go will be directly usable in each
implementation to increase test coverage there as well, but also works at
the top-most level to test arbitrary backends.
