Light node: getTransactionByHash return blockNumber null even after tx is included in block

[amaury1093]

Before filing a new issue, please provide the following information.

• Parity Ethereum version: 2.4.0
• Operating system: MacOS & Linux
• Installation: homebrew
• Fully synchronized: yes
• Network: ropsten & kovan
• Restarted: yes

Repro

• On a light node
• Send a transaction, remember its hash
• Poll eth_getTransactionByHash every 1 second

Expected

• After some time, the blockNumber field in the response should be non-null

Actual

• Always null, even after >20 blocks, and the transaction shows up correctly on etherscan.

Other Notes

• Tried on ropsten & kovan, same behavior
• It's only happening with a light node. On a full-node, after a couple of polls, the blockNumber is non-null as expected.

Hey,

Because the block data is only retrieved with a fixed interval currently every 10th minute it could take 10 minutes to get that data filled after the transaction occurs in a block. We should probably change that do adapt when for example doing a RPC request.

However, I could verify that the block data is eventually filled:
