Fix#303 by changing the addrindex key prefix to 3 characters so that
it's easy to check length when dropping the index. To drop the old
index, check to make sure we aren't dropping any entries that end in
"sx" or "tx" as those aren't part of the addrindex. Update test to
deal with the new prefix length.
Fix#346 by changing the pointers in the mempool's addrindex map to
wire.ShaHash 32-byte values. This lets them be deleted even if the
transaction data changes places in memory upon expanding the maps.
Change the way addrindex uint32s are stored to big-endian in order to
sort the transactions on disk in chronological/dependency order.
Change the "searchrawtransactions" RPC call to return transactions
from the database before the memory pool so that they're returned in
order. This commit DOES NOT do topological sorting of the memory pool
transactions to ensure they're returned in dependency order. This may
be a good idea for a future enhancement.
Add addrindex versioning to automatically drop the old/incompatible
version of the index and rebuild with the new sort method and key
prefix.
- Use explicit index values for byte slices
- Fix a bug in FetchTxsForAddr that allocated an extra 10 bytes
for each address index
- Add missing iterator release in error path
- Check for iterator errors.
This change converts the leveldb database's ExistsSha() and
ExistsTxSha to use the goleveldb API. Has() only returns if
the key exists and does not need to read the entire value into
memory resulting in less disk i/o and much less GC.
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.
