      FAB-631 WIP - pared down peer for next arch work · 9eb99b3f
      Srinivasan Muralidharan authored 
      

Following skeletal end to end flow work, this submit
takes the next steps for Endorser/Committer
  . converts chaincode and endorser to ledgernext
  . removes consensus package
  . chaincode unit tests use ledgernext
  . panics if ledger.GetLedger is called so we
    can catch codepaths that still use that. These
    are mainly core/api and core/peer
  . removes unit tests from core/api and core/ledger
    (to avoid GetLedger calls there)
  . created a minimal core/peernext. core/peer is
    still there for comparison but is not used

      Revert "... uses hardcoded hashcode for example02" · e3fe1e09
      Gregory Haskins authored 
      This reverts commit 5d9a3eab

.

chaincode_example04 calls chaincode_example02 via a hard-coded ID.
This is intentional to catch change to the ID when NOTHING in
chaincode_example02 or in its folder changes.  ie, a test for the
constancy of the hash generation algorithm.

The patch attempt pass the ID as a parameter to prevent accidental
changes to chaincode_example02 from causing test failures. While
well-intented, this subverts the above reasoning behind the
hard-coding.

Also note that chaincode_example05 does take the argument as a
parameter (so that usage is already covered).

      C2C invocation for confidential contracts. · 5f9b3ea0
      Angelo De Caro authored 
      This PR addresses chaincode to chaincode invocation for confidential contracts
(https://jira.hyperledger.org/browse/FAB-67

). In order to achieve the goal
the chaincode handler has been modified to contruct proper ephemeral
transactions and security contexts.

Let us consider the following scenario to describe the modification
apported by this PR. Let us say that we have two chaincodes: A and B
where A invokes B at some point of its computation.
When a user invoke a chaincode A, using transaction tx,
the certificate that the user has put in tx is passed to B when A
invokes it. In this way, for example, chaincode B can perfom
attribute-based access control. In addition,
each chaincode can access it is own encrypted state and modify
it in a proper way without affecting other chaincodes' state.

This PR has been tested by adding a unit test in exectransaction_test.go.
The unit tests, verify that C2C invocation can be perfomed when
security is enabled.

What will come next:
1. Chaincode to chaincode query.
2. Additional fields transfered to the invoked chaincode to
support access control based on signature.

      GitHub Issue #2119 - chaincode unittesting · 23afd056
      Brad Gorman authored 
      

Replaced ChaincodeStub with ChaincodeStubInterface to allow
unit testing of chaincode. MockStub added to emulate a real
chaincode without the storage or network requirements.
Unit test examples for chaincode_example02 to 05.

I have another changeset to address tables and certificates.

      Use repeated bytes instead of repeated string for chaincode call args · fd498d2f
      Gabor Hosszu authored 
      

This allows applications to easily pass arbitrary blobs without having
to serialize them to strings.  At the same time, we also consolidate
the function argument to be part of the repeated bytes args.

For convenience and to simplify porting of existing chaincode to the
new argument format, we introduce helper functions in the shim which
cast between ([][]byte) and (string, []string).

      Refactor db package · 9544025c
      grapebaba authored 
      

Currently db will open when GetDBHandle method is invoked first time,
so GetDBHandle method needs to use mutex.
This patch makes db open and close in its lifecycle methods Start and
Stop, invokes Start only when peer starts and invokes Stop when peer
stops.
After that, methods in db do not need to support concurrency.
