This utility is a relic from initial development before it was possible to
request blocks and transactions via RPC. The correct way to do this now
is by using RPC since that works while btcd is operating unlike the
utility which requires an exclusive lock on the database.
Currently, the reference client bans peers that send alerts not signed
with its key. We could verify against their key, but since the
reference client developers are currently unwilling to support other
implementations' alert messages, we will not relay theirs.
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.
This was previously hard-coded to zero instead of using the offset
provided by the median time source which takes time samples from the other
connected nodes.
Only two operations are performed with this data structure: adding to
the back and removing from the front. Because middle inserts and
deletions are never needed, a linked list results in overall worse
performance due to an extra allocation for each element's node, worse
cache locality, and the runtime cost of boxing/unboxing each item
during accesses.
On top of the performance gains, a slice is more type safe as it is a
true generic data structure making it is impossible to insert or
access an element with the wrong type.
