BUG REPORT

Tendermint version :: 0.8.0

ABCI app :: self-written, not publicly available

Essentially, this is a Java app similar to the Go Counter app. In the context of the error, what it does is the following:

1. Stores the received hash value received in callback requestBeginBlock
2. Stores the received height value received in callback requestEndBlock
3. Returns those two stored values via callback requestInfo

Merkleeyes version :: n/a

Environment

• OS :: Any
• Install tools :: Tendermint from source

What happened

I'm running tendermint node. After killing the process and starting it again, I'm seeing the following error. I assume this is a defect as appHeight and storeHeight are identical.

What you expected to happen

Expecting value 8 for LastBlockHeight seems to be wrong considering the last block height is consistently 7. The 8th block was not even yet created, so why not simply building upon block 7.

How to reproduce it

I assume this could be easily reproduced with a test or the Go Counter example if the Info() function only would return values for properties "last_block_height" and "last_block_app_hash". I see the following reply for Tendermint / Go Counter client / server combination ...
$ curl http://localhost:46657/abci_info {"jsonrpc":"2.0","id":"","result":[113,{"data":"{\"hashes\":259,\"txs\":0}","version":"","last_block_height":0,"last_block_app_hash":""}],"error":""}
