Release 1.0.8

Rework dbHandle

This release complete the rework job of util/dbHandle.

• We changed from using Hyperledger Fabric couchdb util to statecouchdb.VersionedDB to correctly mimic how a peer perform endorse a transaction.

• We change all DB write action to VersionedDB.ApplyUpdates to mimic the transaction batch write process to stateDB

hot fix dependency

Fix dependency for v1.0.8

Add UpdateExistingData

Problem

The current Changeinfo function in daoHandle uses InsertTableRow requiring the engine to perform a GetState before PutState. In some case, we have already performed GetState before (e.g. to check a user balance before deducing his balance). Thus, the current Changeinfo creates an extra GetState to the state database.

Update

We add other functions in utils: UpdateExistingData and UpdateTableRow so that the engine performs PutState directly without checking the state again.

unit test for partial key query

Add unit test supports for those 2 functions:

• GetStateByPartialCompositeKey
• GetStateByPartialCompositeKeyWithPagination

Hot fix akcQueryIterator

Add Close() function for AkcQueryIterator

Change MockStubExtend query behavior

We change MockStubExtend query behavior to query directly from couchdb.
Previously the mock object stores key-value data in an array, which is not consistent with the real Fabric behavior.

Add delete state in couchdb

v1.0.6

Add delete state

Add support for customized couchdb connection string

Previous version only supports localhost couchdb,
we add a new function to support external databases as well
