Notable changes

Node Performance Improvements

This release makes several changes to improve the performance of node operations. These include:

Backported CuckooCache from upstream to improve the performance of signature caching.
Added caching of proof and signature validation results for Sapling and Orchard to eliminate redundant computation.
Backported SHA-256 assembly optimizations from upstream.

Wallet Performance Improvements

This release makes several changes to improve the performance of wallet operations. These include:

We now parallelize and batch trial decryption of Sapling outputs.
We now prune witness data in the wallet for notes spent more than 100 blocks in the past, so that we can avoid unnecessarily updating those witnesses. In order to take advantage of this performance improvement, users will need to start their nodes with -rescan the first time .
The process for incrementing the witnesses for notes the wallet is tracking has been optimized to avoid redundant passes over the wallet.
Removed an assertion that was causing a slowdown in wallet scanning post-NU5.

RPC Interface Changes

A version field was added to the result for the gettransaction RPC call to avoid the need to make an extra call to getrawtransaction just to retrieve the version.

Fixes

Fixed a regression that caused an incorrect process name to appear in the process list.

Changelog

Aditya Kulkarni (1): Add tx version

Kris Nuttycombe (15): scripted-diff: Move utiltest to src/util Add a clock for testing with an offset from the system clock. Apply suggestions from code review Add persistent Sprout test data. Remove the temporary test that was used for setup of the cached Sprout fixtures. Add RPC test initialization using the persisted Sprout chains. Update sprout_sapling_migration test to use persisted sprout chains. Update feature_zip239 test to use persisted sprout chains. Add missing header to util/time.h Update finalsaplingroot test to use persisted sprout chains. Update getblocktemplate test to use persisted sprout chain Replace setup_clean_chain with cache_behavior in rpc test init. qa: Postpone recent native_rust, native_cxxbridge and rustcxx updates make-release.py: Versioning changes for 5.2.0-rc1. make-release.py: Updated manpages for 5.2.0-rc1.

Luke Dashjr (3): configure: Invert --enable-asm help string since default is now enabled configure: Skip assembly support checks, when assembly is disabled configure: Initialise assembly enable_* variables

Marshall Gaucher (2): Update entrypoint.sh Update contrib/docker/entrypoint.sh

Pieter Wuille (34): Allow non-power-of-2 signature cache sizes Do not store Merkle branches in the wallet. Avoid duplicate CheckBlock checks Add merkle.{h,cpp}, generic merkle root/branch algorithm Switch blocks to a constant-space Merkle root/branch algorithm. Add FastRandomContext::rand256() and ::randbytes() scripted-diff: Rename cuckoo tests' local rand context Merge test_random.h into test_bitcoin.h Add various insecure_rand wrappers for tests scripted-diff: use insecure_rand256/randrange more Replace more rand() % NUM by randranges Replace rand() & ((1 << N) - 1) with randbits(N) Use randbits instead of ad-hoc emulation in prevector tests scripted-diff: Use randbits/bool instead of randrange where possible scripted-diff: Use new naming style for insecure_rand* functions Support multi-block SHA256 transforms Add SHA256 dispatcher Add SSE4 based SHA256 Add selftest for SHA256 transform Protect SSE4 code behind a compile-time flag Benchmark Merkle root computation Refactor SHA256 code Specialized double sha256 for 64 byte inputs Use SHA256D64 in Merkle root computation 4-way SSE4.1 implementation for double SHA256 on 64-byte inputs 8-way AVX2 implementation for double SHA256 on 64-byte inputs [MOVEONLY] Move unused Merkle branch code to tests Enable double-SHA256-for-64-byte code on 32-bit x86 Improve coverage of SHA256 SelfTest code For AVX2 code, also check for AVX, XSAVE, and OS support [Refactor] CPU feature detection logic for SHA256 Add SHA256 implementation using using Intel SHA intrinsics Use immintrin.h everywhere for intrinsics Avoid non-trivial global constants in SHA-NI code
