28 hours | test: Use span for raw data | MarcoFalke | |
This change allows to drop brittle sizeof calls in favor of the std::span::size method. Other improvements include: * Use of a namespace to mark test and bench data * Use of the modern std::byte * Drop of a no longer used std::vector copy and the bench/data module | |||

2023-12-07 | refactor: rpc: Pass CBlockIndex by reference instead of pointer | MarcoFalke | |
All functions assume that the pointer is never null, so pass by reference, to avoid accidental segfaults at runtime, or at least make them more obvious. Also, remove unused c-style casts in touched lines. Also, add CHECK_NONFATAL checks, to turn segfault crashes into an recoverable runtime error with debug information. | |||

2023-05-09 | refactor: Replace string chain name constants with ChainTypes | TheCharlatan | |
This commit effectively moves the definition of these constants out of the chainparamsbase to their own file. Using the ChainType enums provides better type safety compared to passing around strings. The commit is part of an ongoing effort to decouple the libbitcoinkernel library from the ArgsManager and other functionality that should not be part of the kernel library. | |||

2022-10-20 | bench: explicitly make all current benchmarks "high" priority | furszy | |
no-functional changes. Only have set the priority level explicitly on every BENCHMARK macro call. | |||

[META] In the next commit, we move the clearing of fHavePruned to BlockManager::Unload() | |||
2022-01-02 | Use spans of std::byte in serialize | MarcoFalke | |
This switches .read() and .write() to take spans of bytes. | |||

2021-02-13 | Add benchmark to write JSON into a string | Martin Ankerl | |
The benchmark BlockToJsonVerbose only tests generating (and destroying) the JSON data structure, but serializing into a string is also a performance critical aspect of the RPC calls. Also, use ankerl::nanobench::doNotOptimizeAway to make sure the compiler can't optimize the result of the calls away. | |||
2021-01-24 | Fix BlockToJsonVerbose benchmark | Martin Ankerl | |
Currently it was not possible to run just the BlockToJsonVerboes benchmarsk because it did not set up everything it needed, running `bench_bitcoin -filter=BlockToJsonVerbose` caused this assert to fail: ``` bench_bitcoin: chainparams.cpp:506: const CChainParams& Params(): Assertion `globalChainParams' failed. ``` Initializing TestingSetup fixes this. | |||
2020-06-13 | Replace current benchmarking framework with nanobench | Martin Ankerl | |
This replaces the current benchmarking framework with nanobench [1], an MIT licensed single-header benchmarking library, of which I am the autor. This has in my opinion several advantages, especially on Linux: * fast: Running all benchmarks takes ~6 seconds instead of 4m13s on an Intel i7-8700 CPU @ 3.20GHz. * accurate: I ran e.g. the benchmark for SipHash_32b 10 times and calculate standard deviation / mean = coefficient of variation: * 0.57% CV for old benchmarking framework * 0.20% CV for nanobench So the benchmark results with nanobench seem to vary less than with the old framework. * It automatically determines runtime based on clock precision, no need to specify number of evaluations. * measure instructions, cycles, branches, instructions per cycle, branch misses (only Linux, when performance counters are available) * output in markdown table format. * Warn about unstable environment (frequency scaling, turbo, ...) * For better profiling, it is possible to set the environment variable NANOBENCH_ENDLESS to force endless running of a particular benchmark without the need to recompile. This makes it to e.g. run "perf top" and look at hotspots. Here is an example copy & pasted from the terminal output: | ns/byte | byte/s | err% | ins/byte | cyc/byte | IPC | bra/byte | miss% | total | benchmark |--------------------:|--------------------:|--------:|----------------:|----------------:|-------:|---------------:|--------:|----------:|:---------- | 2.52 | 396,529,415.94 | 0.6% | 25.42 | 8.02 | 3.169 | 0.06 | 0.0% | 0.03 | `bench/crypto_hash.cpp RIPEMD160` | 1.87 | 535,161,444.83 | 0.3% | 21.36 | 5.95 | 3.589 | 0.06 | 0.0% | 0.02 | `bench/crypto_hash.cpp SHA1` | 3.22 | 310,344,174.79 | 1.1% | 36.80 | 10.22 | 3.601 | 0.09 | 0.0% | 0.04 | `bench/crypto_hash.cpp SHA256` | 2.01 | 496,375,796.23 | 0.0% | 18.72 | 6.43 | 2.911 | 0.01 | 1.0% | 0.00 | `bench/crypto_hash.cpp SHA256D64_1024` | 7.23 | 138,263,519.35 | 0.1% | 82.66 | 23.11 | 3.577 | 1.63 | 0.1% | 0.00 | `bench/crypto_hash.cpp SHA256_32b` | 3.04 | 328,780,166.40 | 0.3% | 35.82 | 9.69 | 3.696 | 0.03 | 0.0% | 0.03 | `bench/crypto_hash.cpp SHA512` [1] https://github.com/martinus/nanobench * Adds support for asymptotes This adds support to calculate asymptotic complexity of a benchmark. This is similar to #17375, but currently only one asymptote is supported, and I have added support in the benchmark `ComplexMemPool` as an example. Usage is e.g. like this: ``` ./bench_bitcoin -filter=ComplexMemPool -asymptote=25,50,100,200,400,600,800 ``` This runs the benchmark `ComplexMemPool` several times but with different complexityN settings. The benchmark can extract that number and use it accordingly. Here, it's used for `childTxs`.
