Request to update
Hi cendhu,
is this tool still compatible with current version of HLF (version 1.3)? The problem is I received this error while trying to start fetch_block:
Starting Client
error on Register send rpc error: code = Internal desc = transport is closing
could not start chat rpc error: code = Internal desc = transport is closing
Error starting EventClient
Thank you.
It is not compatible with v1.3. I will make it work with v1.4 (which should work for 1.2 and 1.3). Please give me a month time and I will push a patch.
@cendhu Hi Senthil,
I am looking for a way to inspect HLF 1.2/1.4 blockchain. I am eager to help you and would like to allocate extra resources for porting this solution to new versions of HL. How can we get in touch and discuss possible cooperation? Probably you could steer me or share the vision on what has to be done, so I would not start from scratch?
@aaxx Sorry for the delay in update. I will be busy till Feb end. In the first week of March, I will push updates. Can you please wait till that time?
@cendhu Unfortunately not. Is there any way to take a look on current state of the update? I plan to complete that in a week. Would not like to do that from scratch
We have added additional details in rwset for the private data. Now, each rwset would contain pubUpdates and hashedUpdates. PvtUpdates are not included in the block. According to this new block structure, we need to change the fetch-block implementation. Further, the event mechanism in v1.4 has changed. Hence, some additional work is needed with respect to initial connections. If there is any urgency required, there is another alternative. Using SDK, we can call QSCC chaincode for retrieving the block by number. I hope, SDK (at least node) provides API for decoding the block. I have worked only in the backend not in SDK (hence, not aware of it much).
