b1d905c225p2p: earlier continuation when no remaining eviction candidates (Vasil Dimov)c9e8d8f9b1p2p: process more candidates per protection iteration (Jon Atack)02e411ec45p2p: iterate eviction protection only on networks having candidates (Jon Atack)5adb064574bench: add peer eviction protection benchmarks (Jon Atack)566357f8f7refactor: move GetRandomNodeEvictionCandidates() to test utilities (Jon Atack) Pull request description: This follow-up to #21261 improves `ProtectEvictionCandidatesByRatio()` for better performance. Benchmarks are added; the performance improvement is between 2x and 5x for the benchmarked cases (CPU 2.50GHz, Turbo off, performance mode, Debian Clang 11 non-debug build). ``` $ ./src/bench/bench_bitcoin -filter="EvictionProtection*.*" ``` The refactored code is well-covered by existing unit tests and also a fuzzer. - `$ ./src/test/test_bitcoin -t net_peer_eviction_tests` - `$ FUZZ=node_eviction ./src/test/fuzz/fuzz ../qa-assets/fuzz_seed_corpus/node_eviction` ACKs for top commit: klementtan: Tested and code review ACKb1d905c2. vasild: ACKb1d905c225jarolrod: ACKb1d905c225Tree-SHA512: a3a6607b9ea2fec138da9780c03f63e177b6712091c5a3ddc3804b896a7585216446310280791f5e20cc023d02d2f03a4139237e12b5c1d7f2a1fa1011610e96
Test library
This contains files for the test library, which is used by the test binaries (unit tests, benchmarks, fuzzers, gui tests).
Generally, the files in this folder should be well-separated modules. New code should be added to existing modules or (when in doubt) a new module should be created.
The utilities in here are compiled into a library, which does not hold any state. However, the main file setup_common
defines the common test setup for all test binaries. The test binaries will handle the global state when they
instantiate the BasicTestingSetup (or one of its derived classes).
