Chia-blockchain

Added

- Added RPC updates to support keyring migration and to support adding a passphrase for wallets in an upcoming release.
- Added plot memo caching in PlotManager, speeding initial loading and cached loading, by enabling harvester to save the parsed plot memo on disk on shutdown, then load it back into memory on startup so that it can skip key parsing calculations for all already known plots.
- Added a debug option to log all SQL commands.
- Added support for DID, our decentralized identity solution, as a building block toward Chia's broader set of DID capabilities.
- Thanks olivernyc for the addition of a query in CoinStore to special case height 0 to avoid querying all unspent coins.
- Starting logging the timing of applying additions and removals to the coin store.
- Made max message size configurable in config.yaml, as a possible workaround for very large farms where reporting plot information exceeds the maximum message size.
- Added a config option for peer_connect_timeout.
- Added support for unhardened key derivations.
- Various CoinStore benchmark and performance improvements.
- Beta builds are built on every merge to main, and are now available from <https://chia.net/download/>.
- Thanks Radexito for adding support for Raspberry Pi 4 64Bit to the GUI installation script.
- Added macOS keyring.yaml support, migrating keys from macOS Keychain to keyring.yaml to support an upcoming release in which we'll add an optional passphrase to wallets.
- We have made many full node changes to support our upcoming Chia Asset Token (CAT) standard and our upcoming standalone light wallet, which will use Chia's new electrum-style protocol to enable faster wallet syncing.
- We have many new translations added in this release.

Changed

- Bluebox proofs are now randomized instead of looking at the oldest part of the blockchain first to find uncompacted proofs.
- Bumped sortedcontainers to version 2.4.0.
- Dropped some redundant code in plotting/manager.py
- Updated some hooks: Update `flake8` to 3.9.2, `pre-commit-hooks` to 4.0.1, `black` to 21.8b0
- Bump clvm_rs to 0.1.14.
- Added tests for invalid list terminators in conditions.
- Updated blspy to 1.0.6.
- Made a change to allow the host to be configurable for the timelord launcher.
- Thanks dkackman for adding the ability to collect the IDs of plots as they are queued and return them with the response.
- Made the SpendBundle.debug use the default genesis challenge by default.
- Changes in full node to execute sqlite pragmas only once, at the level where the database is opened, and changed pragma synchronous=FULL to OFF to improve disk I/O performance. Also removed redundant database pragmas in wallet.
- Made a change to remove CoinStore's dependency on FullBlock to just pass in the parts of the block necessary to add the block.
- Improved log formatting.
- A change to logging to only log warnings when more than 10 seconds has passed, to reduce the number of warning logs.
- Improved and fixed some outdated messages in CLI. Thanks jack60612 for the assist!
- We previously added a Rust condition checker, to replace our existing Python-based condition checker. In this release, we're removing the old Python code.
- Several clvm_rs updates to support our upcoming Chia Asset Token (CAT) standard.

Fixed

- Thanks mgraczyk for the fix to keyring_path.
- Fixed an issue blocking the Ubuntu installer that required manual installation of Python 3.9 as a workaround.
- Fixed an issue where the config.yaml and keyring.yaml are only partially written out to, if another process is attempting to read the config while it's being written.
- Fixed rmtree call in create_pool_plot.
- Thanks Knight1 for fixing an issue in which fix-ssl-permissions shows the current 'mode' not the 'updated mode'.
- Fixed Mypy issues on Python 3.9.7 that generated many errors when running mypy.
- Thanks olivernyc for fixing an edge case with negative inputs to 'truncate_to_significant_bits'.
- Added a fix for Windows installs that were seeing exceptions when writing to the keyring.

Fixed

- Thanks to jack60612 for fixing a bug that displayed 25 words instead of 24 words in some instances in the GUI.

Today we’re releasing version 1.2.6 to address a resource bug with nodes, and we want to stress the importance of updating to it at the earliest convenience. The fix prevents a node from consuming excessive memory when many Bluebox Timelords are active on the chain.

Changed

- Updated to BLS 1.0.6.
- Updates to the Rust conditions parser.
- Adjusted plot refresh parameter to improve plot loading times.

Fixed

- Fixed memory utilization issue related to how the node handles compact VDFs generated from blueboxes. We recommend everyone update to this version to avoid memory issues that can impact farming and harvesting.
- Fixed issues with reloading plot files detected as bad (this can happen during plot copying).

Fixed

- Fixed errors in the Linux GUI install script, which impacted only Linux users.

Added

- Enable the rust condition checker unconditionally in testnet.
- Added support for multiple wallets.
- Added a change to config.yaml to tolerate fields that replace network constants in config.yaml that don't exist, but print warning.
- Improvements to sync full nodes faster by improving the concurrency for downloading and validating blocks.
- Added new call for logging peer_host: get_peer_logging that will use the peer_host value, typically an IP address, when the peername cannot be retrieved.
- Added documentation for treehash params.
- Added a py.typed file that allows other projects that pip install chia-blockchain to type check using our functions with mypy.
- Added an RPC for coin records by multiple coin names.
- Enabled querying AAAA records for DNS Introducer.
- We now set the version for the GUI when doing a manual install using the install-gui.sh script. Uses a python helper to get the version of the chia install and then converts it into proper npm format and puts that into package.json.
- Added some new class methods to the Program objects to improve ease of use.
- Added an option to sign bytes as well as UTF-8 strings, which is particularly helpful if you're writing Chialisp puzzles that require signatures and you want to test them without necessarily writing a whole python script for signing the relevant data.
- Added a first version of .pre-commit-config.yaml and applied the changes required by the following initial hooks in separate commits. To use this you need to install pre-commit, see <https://pre-commit.com/#installation/>.
- We have added many new translations in this release based on community
submissions. Thanks to RuiZhe for Chinese, Traditional; HansCZ for Czech;
LUXDAD for English, Australia; f00b4r for Finnish; jimkoen, ruvado for German; Arielzikri for Hebrew; A-Caccese for Italian; Hodokami for Japanese; LUXDAD for Latvian; vaexperience for Lithuanian; LUXDAD for Russian; juands1644 for Spanish, Argentina; MrDyngrak, ordtrogen for Swedish; richeyphu for Thai; Ansugo, baturman for Turkish.

Changed

- Thanks altendky for Correct `*` to `**` kwargs unpacking in time_out_assert().
- Thanks altendky for changing the default to paginate to chia wallet get_transactions to address cases such as piping and output redirection to a file where the command previously just hung while waiting for the user to press c for the next page.
- Removed commented-out debug breakpoints.
- Enabled Rust condition checker to add the ability to parse the output conditions from a generator program in Rust. It also validates some of the conditions in Rust.
- Switched IP address lookup to first use Chia's service ip.chia.net.
- Made changes so that when creating SSL certificate and private key files, we ensure that files are written with the proper file permissions.
- Define a new encrypted keyring format to be used to store keys, and which is optionally encrypted to a user-supplied passphrase. GUI for the passphrase will come in an upcoming release.
- Removed initial transaction freeze put in place at mainnet launch as it is no longer necessary.
- Separate locking and non-locking cases for get_confirmed_balance_for_wallet, which will allow calling a few wallet_state_manager methods while already under the wallet_state_manager lock, for example during DID wallet creation.
- Thanks to Playwo for removing the index on coin_record spent column to speed up querying.
- Made a change to the conditions parser to either ignore or fail when it encounters unknown conditions. It also removes the UNKNOWN enum value from ConditionOpcodes.
- Renamed folder tests/core/types to tests/core/custom_types to address conflicts in debugger in PyCharm.
- Disabled DID wallet tests while DID wallet is under construction.
- Added pairing cache for faster aggregate signature verification.
- Added block height assertions after block farming.
- Added assertions for tx confirmation.

Fixed

- Fix single coin generator.
- Fixed an issue with duplicate plotnft names.
- Fixed an issue during node shutdown in which some AttributeErrors could be thrown if the shutdown happens before the node fully started up.
- Fixed mempool TX cache cost, where the cost of the mempool TX cache (for spend bundles that can't be included in a block yet) would not be reset when the cache was emptied.
- Fixed a failure to create a keychain_proxy for local keychains.
- Thanks to mgraczyk for fixing type annotation in sync_store.
- Thanks to darkverbito for fixing an issue on initial creation of a coloured coin where code always falls into default else clause due to lack of type conversion.
- Fixed NPM publish in clvm_rs.
- Thanks to skweee for his investigation work on fixing mempool TX cache cost, where the cost of the mempool TX cache (for spend bundles that can't be included in a block yet) would not be reset when the cache was emptied.

Added

- Added ability to change payout instructions in the GUI.
- Added an option to revert to sequential read. There are some systems (primarily macos+exfat) where the parallel read features results in very long lookup times. This addition makes the parallel feature the default, but adds the ability to disable it and revert back to sequential reads.
- Added backwards compatibility for Coin Solutions in push_tx since renaming it to CoinSpend.
- Added an option to set the default constants on the simulator.
- Added a warning to user to not send money to the pool contract address.
- Added capability to enable use of a backup key in future, to claim funds that were sent to p2_singleton_puzzle_hash, which today are just ignored.
- Thanks aarcro for adding timing metrics to plot check.
- Thanks chadwick2143 for adding the ability to set the port to use for the harvester.
- Added more friendly error reporting for peername errors.

Changed

- Updated blspy to 1.0.5.
- Updated chiapos to 1.0.4.
- Included all Chialisp files in source distribution.
- Removed left-over debug logging from test_wallet_pool_store.
- Made changes to allow us to use the name coin_spend everywhere in our code, without changing it in the API requests, both outgoing and incoming. Enables us to decide at a later date when to cut over completely to the coin_spend name.
- Thanks mishan for your change to 'chia plotnft show' to display Percent Successful Points.
- Thanks Playwo for your change to make pool payout instructions case insensitive.
- GUI sees update when plots or harvesters change.
- Increased the cache interval to help large farmers.
- Removed proof limit for mainnet, but not testnet. This helps with pools that have very low difficulties. Thanks to AlexSSD7 for pointing out the issue.
- We now also allow hex strings prefixed with 0x which is required because we currently prefix the strings in JSON conversion.
- Thanks to opayen for your help in updating our MacOS icon.

Fixed

- Thanks to dfaranha for helping fix a parsing error in Relic inputs for BLS signatures.
- Fixed error type in wallet_blockchain.py.
- Thanks to seraphik for a fix on our Linux installer that required root privileges.
- Thanks felixbrucker for helping fix invalid content-type header issues in pool API requests.
- The wallet ignores coins sent by accident to the pool contract address and allows self pooling rewards to be claimed in this case.
- Thanks mgraczyk for fixing the use of print_exc in farmer.
