v0.14.1 (2019-06-16)

Bug Fixes

#1019: Miner log wrong block hash (@quake)
#1025: Miner time interval panic (@quake)

v0.14.0 (2019-06-15) rylai-v3

BREAKING CHANGES

Important: The default secp256k1 code hash is changed to 0xf1951123466e4479842387a66fabfd6b65fc87fd84ae8e6cd3053edb27fff2fd. Remember to update block assembler config.

This version is not compatible with v0.13.0, please init a new CKB directory.

Features

#913: New verification model (@xxuejie)

This is a breaking change: b:consensus, b:database, b:p2p, b:rpc

Based on feedbacks gathered earlier, we are revising our verification model with the following changes:
- When validating a transaction, CKB will grab all lock scripts from all inputs, and group them based on lock script hash. The script in each group will only be run once. The lock script itself will have to do the validation task for all inputs in the same group
- CKB will also grab all type scripts from inputs and outputs(notice different from previous version, the type scripts in inputs are included here as well), and group them based on type script hash as well. Each type script in each group will also be run once. The type script itself needs to handle the validation task within the group
- Syscalls are also revised to allow fetching all the inputs/outputs/witnesses within a single group.
- Input args is removed since the functionality can be replicated elsewhere
#908: Peers handle disconnect (@keroro520)

#845: Limit TXO set memory usage (@yangby-cryptape)

This is a breaking change: b:database
#874: Revise uncle rule (@zhangsoledad)

This is a breaking change: b:consensus, b:database
1. get rid uncle age limit
2. try include disconnected block as uncle
#920: Tweak consensus params (@zhangsoledad)

This is a breaking change: b:consensus

tweak block_cycles_limit and min_block_interval
#897: Wrap the log macros to fix ill formed macros (@yangby-cryptape)

And, we have to update the log filters, add prefix ckb- for all our crates.

#924: Add a transaction error InsufficientCellCapacity (@yangby-cryptape)
#926: Make a better error message for miner when method not found (@yangby-cryptape)
#961: Display miner worker status (@quake)

BREAKCHANGE: config file ckb-miner.toml changed
#1001: ckb init supports setting block assembler (@doitian)
- ckb init accepts options --ba-code-hash and --ba-arg (which can repeat multiple times) to set block assembler.
- ckb cli secp256k1-lock adds an output format cmd to prints the command line options for ckb init to set block assembler.
The two commands can combine into one to init the directory with a secp256k1 compressed pub key:
```
  ckb init $(ckb cli secp256k1-lock <pubkey> --format cmd)
```
#996: Tweak consensus parameters (@doitian)
- Change target epoch duration to 4 hours
- Reduce epoch reward to 1/4
- Increase secondary epoch reward to 600,000 bytes

Bug Fixes

#878: Calculate the current median time from tip (@keroro520)

This is a breaking change: b:consensus

Original implementation use [Tip-BlockMedianCount .. Tip-1] to calculate the current block median time. According to the notion of BlockMedianTime in bip-0113 , here change to use [Tip-BlockMedianCount+1 .. Tip] instead.
#915: Sync blocked by protected peer (@TheWaWaR)
#906: Proposal table reload (@zhangsoledad)

#841: Apply tx_pool limit (@zhangsoledad)

This is a breaking change: b:cli, b:rpc

apply tx_pool limit
tx size verify, enforce tx size below block size limit

BREAKING CHANGES:

config ckb.toml

[tx_pool]
- max_pool_size = 10000
- max_orphan_size = 10000
- max_proposal_size = 10000

#890: Revise remainder reward rule (@zhangsoledad)

This is a breaking change: b:consensus
#876: Tweak consensus params (@zhangsoledad)

This is a breaking change: b:consensus
#889: Add codename in version (@doitian)
#854: Calculate median time by tracing parents (@keroro520)

At present, the way calculating the passed median time is that collects block timestamps one by one by block_number. This PR change to collects blocks timestamps by tracing parents. The new way is more robust.

In addition to this, I use assert-style to rewrite the calculation of passed median time.

#859: Use snappy to compress large messages (@driftluo)

This is a breaking change: b:p2p

On the test net monitoring, the bandwidth usage is often in a full state. We try to use the snappy compression algorithm to reduce network transmission consumption.

After testing, the compression yield of flatbuffer format is very high, cpu consumption is relatively acceptable.

The following is the data transmission on the test net:

Note that this is a break change, the data is modified as follows:

By default, data above 40k enters compressed mode.

From the current point of view, the high bit 1 is the compressed format and the high bit 0 is the uncompressed format.

If you want to support multiple compression formats in the future, you can simply think that 0b1000 is in snappy format and 0b0000 is in uncompressed format.

BREAKING CHANGES

This release has changed the underlying database format, please delete the old data directory before running the new version.
RPC get_live_cell returns (null, "unknown") when looking up null out point before, while returns (null, "live") now.
RPC uses string to encode all 64bit integrers now.
The executble ckb requires config files now, use ckb init to export the default ones.
The new features tx valid sicne (#372) and removal of version from Script (#422) have changed the core data structure. They affect both RPC and the P2P messages flatbuffers schema.

The testnet chain spec is also changed, which is incompatible with previous versions.

Command line argument -c is removed, and a new command line argument -C is added. See ckb help for details.

Now the command ckb no longer searches the config file nodes/default.toml. It looks for the config file ckb.toml or ckb-miner.toml in current directory and uses the default config options when not found. A new command ckb init is added, see its usage with ckb init --help.

Config file ckb.toml changes:

Removed logger.file, db.path and network.path from config file.
Added config option logger.log_to_stdout and logger.log_to_file.
Section block_assembler now accepts two options binary_hash and args.
Added a new option to set sentry DSN.

File miner.toml changes:

Option spec is moved under chain, which is consistent with ckb.toml.
Move miner own config options under section miner.
Remove logger.file from config file.
Add config option logger.log_to_stdout and logger.log_to_file.

It is recommended to export the config files via ckb init, then apply the modifications upon the new config files.

v0.8.0 (2019-04-08)

Features

#336: index whether a tx is a cellbase in the chain r=quake a=u2

Index whether a tx is a cellbase in the chain, prepare for the cellbase outputs maturity checking.

Now saving the cellbase index and block number in the TransactionMeta, there is another implementation which creates a HashMap<tx_hash, number>. The second one may be a little memory saving, but this one is more simple. I think both are ok.
