Release process for 0.19.0 #16996

laanwj commented at 12:45 PM on September 30, 2019: member

Before 0.19 split-off

Update bips.md to account for changes since the last release (#16997).
Update hardcoded seeds (#16999).
Update src/chainparams.cpp (#17002)
- nMinimumChainWork with information from the getblockchaininfo rpc.
- defaultAssumeValid with information from the getblockhash rpc.
  - The selected value must not be orphaned so it may be useful to set the value two blocks back from the tip.
  - Testnet should be set some tens of thousands back from the tip due to reorgs there.
  - This update should be reviewed with a reindex-chainstate with assumevalid=0 to catch any defect that causes rejection of blocks in the past history.
- m_assumed_blockchain_size and m_assumed_chain_state_size with the current size plus some overhead (see this for information on how to calculate them).
- chainTxData with statistics about the transaction count and rate. Use the output of the RPC getchaintxstats, see this pull request for an example. Reviewers can verify the results by running getchaintxstats <window_block_count> <window_last_block_hash> with the window_block_count and window_last_block_hash from your output.

Anyone want to fix this: #16957 (comment) ?

laanwj commented at 1:39 PM on November 6, 2019: member

I found it very hard to describe the change (because the same dbcache value uses less real memory…). Something like:?

The chainstate takes about 9% less memory, at the same time making -dbcache accounting more accurate (it was underestimating the use of memory before). This has the effect that -dbcache can be increased from say, 450 in previous versions to 500 in this versions with the same real memory use, but have more cache available for increased performance.

I added a line to the draft notes in the wiki partly based on @laanwj's text above: https://github.com/bitcoin-core/bitcoin-devwiki/wiki/0.19.0-Release-Notes-Draft/_compare/afe4767a0b9d867f376f487ad4fff2a180b50d7b...3123059fc822840ace61c24129a4291b93c7aa60

Anything left to do for the release or is it good to go?

laanwj commented at 9:35 PM on November 6, 2019: member

I don't think so, maybe we should discuss in the meeting tomorrow.
