Chinilla-blockchain

Added

- This is the initial release of our DNS introducer. We built a far too simple basic introducer that we hoped to replace as quickly as possible with an introducer that uses DNS in the style of Bitcoin. This release will now use both and as we gain testing with the DNS version, we will slowly be phasing the classic introducers out. This should significantly help in finding nodes to connect and sync to.
- You can now whitelist networks and hosts so that a node can always connect with chosen peers.
- We added a simple profiler to track performance times in the application (see /chinilla/util/profiler.py for instructions).
- We added a transaction filter to get_header_blocks_in_range.
- There is now an unspent coin count and pending coin removal count to wallet_rpc_api.
- Added configuration options for moving an install to testnet and back (use `chinilla configure -t true|false`).

Changed

- Performance improvement of speeding up outbound connections.
- Performance improvements to block_store.
- Optimized Streamable parsing by avoiding extra post-init checks, making parsing block records from database up to 40% faster.
- Made the serialization of Coin follow the normal protocol of implementing stream().
- Minor improvements to add_spendbundle and weight proofs.
- We now use version 1.0.2 of chinillapos. We now reopen files on read or write failure with thanks to mreid-moz! We also prevent chinillapos prover crashing for more bad plots.
- Disabled deletion of running plot for Windows users as the crash/lockup bug has returned.
- We more clearly prohibit root from installing/running the GUI.
- Thanks to sargonas for improvements to the template for creating Issues.
- Thanks to aisk for continuing to add more types.
- Thanks for dkackman for improving the remote harvester setup by having init -c only copy the right certs.
- And thank you to vidschofelix, meawoppl, and rongou for various other changes and improvements.

Fixed

- Fixed a bug where multiple wallets running at the same time would all issue a transaction.
- Fixed issues with signage points: duplicate signage point spikes, and bugs in signage point cache.
- Fixed a blank screen error during Centos install.
- Thanks to linnik for fixing a TypeError exception in case of unresponsive service.
- Thanks to msg7086 for fixing install.sh for Debian.
- And thank you to alfonsoperez, asdf2014, fredericosilva, lamba09, Nikolaj-K, sargonas, aisk, Ich5003, and trumankain for various other fixes and improvements.

Fixed

- We were not checking for negative values in the uint64 constructor. Therefore coins with negative values were added to the mempool. These blocks passed validation, but they did not get added into the blockchain due to negative values not serializing in uint64. Farmers making these blocks would make blocks that did not make it into or advance the chain, so the blockchain slowed down starting at block 255518 around 6:35AM PDT 5/9/2021. The fix adds a check in the mempool and block validation, and does not disconnect peers who send these invalid blocks (any peer 1.1.4 or older), making this update not mandatory but is recommended. Users not updating might see their blocks get rejected from other peers. Upgraded nodes will show an error when they encounter an old node trying to send an invalid block. This "Consensus error 124..." can be safely ignored.

Changed

- Secret wallet key is hidden by default in `chinilla keys show`. Use `chinilla keys show --show-mnemonic-seed` for private keys.
- Performance improvement while parsing variable length field in transaction blocks.

Fixed

- Spends are now sorted in the mempool by fee/cost.
- Resolved pending transaction issue during reorgs.
- Fixed bug in message send retry logic.
- Two issues with processing Weight Proofs during syncing while farming.
- Fixed a bug in the outgoing rate control logic that could prevent messages being sent.

Added

- Significant speed improvements have been added to the Node during P2P operations. This is mostly a performance improvement to make sure there is plenty of overhead in Node for transaction processing. Smaller machines like the Pi 4 are strongly advised to update to this release before Monday 5/3/21 at 10AM PDT when transactions start.
- Significant syncing speed improvements have been added. However, there is a lot of low hanging fruit to continue to increase overall chain sync speed in subsequent releases.

Changed

- We now require node 12.x to build the GUI. Installers have been building using node 12.x for quite some time.
- Node will now farm while syncing.
- We changed chinillalisp singletons to take a puzzlehash as its origin. We also updated the DID wallet to use this.
- Transactions are now cached for 10 minutes in mempool to retry if there is a failure of a spending attempt.
- Thank you to Chida82 who made the log rotation count fully configurable. Apologies to him for not initially being included here.
- Thank you to fiveangle for making install.sh more resilient across python installations.
- Standard transactions now all have announcements.
- VDF verification during sync and normal operations are now cached to enhance node performance.
- Target peer count has been increased from 60 to 80 to increase the number of peer Nodes available to connect to. Outbound connections were lowered from 10 to 8.
- The streamables class has had significant performance improvements.
- If a proof of space lookup takes longer than 5 seconds we will now log an error at WARNING level.
- Allow configuration of the plot loading interval (default is 2 minutes) in config.yaml.
- CLI wallet UI was improved and shows syncing status of wallet.
- martomi added logging of added coins back.
- Thank you to aisk for additional type checking.
- aisk added error checking in bech32m
- Chinillalisp programs now remained serialized in Node for better performance.
- Mempool is now set to be 50 times the single block size.
- Mitigate 1-3 vojo dust attacks.
- CLI now switches to EiB for netspace display as appropriate.

Fixed

- We fixed excess memory use when displaying plot logs in GUI. This was causing the GUI application to fail in many "fun" ways after plotting a lot of plots in parallel.
- Fixed plot update issues in the GUI.
- Long syncing will now correctly show "Syncing" around the application.
- Nonce collisions in request IDs is fixed.
- Some duplicate plots were not being caught and logged by harvester on loading.
- We have removed many places where Node was making duplicate requests of other nodes.
- Daemon now waits for services to end to attempt to avoid zombie processes.
- Node is less likely to lose sync due to state inconsistency.
- A large thank you to sargonas for diagnosing why so many technical support questions were flooding GitHub issues, PRing a fix, and mass migrating issues to Discussions.
- Thanks to jeolcho for fixing a bug in full_node_rpc_api.py.
- Thanks antoniobg for a typo fix in keychain.py.
- Thanks to altendky for catching a Copyright date error.

Changed

- Weight proof time outs have been increased from 3 minutes to 6 minutes.

Fixed

- When attempting to sync, connections could accidentally disconnect for rate limiting reasons. This was causing many to not be able to sync.
- Some temp files were not being closed during GUI plotting.

Added

- This is a bug fix release for 1.1.0. It is not required to upgrade from 1.1.0 if you are not experiencing the specific issue that it addresses. You are required to upgrade from any 1.0.x version before Monday evening PDT to continue farming.

Changed

- Logging now includes year, month, and date. Thanks and apologies for not tipping the hat sooner to alfonsoperez for the PR.

Fixed

- Changes were made in 1.1.0 to make sure that even out of order signage points were found and responded to by as many farmers as possible. That change lead to a situation where the harvester could thrash on the same cached signage point.
