2022-08-03tests: Reduce calls to InitS*Cache()Carl Dong
In src/test/fuzz/script_sigcache.cpp, we should really be setting up a full working BasicTestingSetup. The initialize_ function is only run once anyway. In src/test/txvalidationcache_tests.cpp, the Dersig100Setup inherits from BasicTestingSetup, which should have already set up a global script execution cache without the need to explicitly call InitScriptExecutionCache.
2020-12-15Merge #20560: fuzz: Link all targets onceMarcoFalke
fa13e1b0c52738492310b6b421d8e38cb04da5b1 build: Add option --enable-danger-fuzz-link-all (MarcoFalke) 44444ba759480237172d83f42374c5c29c76eda0 fuzz: Link all targets once (MarcoFalke) Pull request description: Currently the linker is invoked more than 150 times when compiling with `--enable-fuzz`. This is problematic for several reasons: * It wastes disk space north of 20 GB, as all libraries and sanitizers are linked more than 150 times * It wastes CPU time, as the link step can practically not be cached (similar to ccache for object files) * It makes it a blocker to compile the fuzz tests by default for non-fuzz builds #19388, for the aforementioned reasons * The build file is several thousand lines of code, without doing anything meaningful except listing each fuzz target in a highly verbose manner * It makes writing new fuzz tests unnecessarily hard, as build system knowledge is required; Compare that to boost unit tests, which can be added by simply editing an existing cpp file * It encourages fuzz tests that re-use the `buffer` or assume the `buffer` to be concatenations of seeds, which increases complexity of seeds and complexity for the fuzz engine to explore; Thus reducing the effectiveness of the affected fuzz targets Fixes #20088 ACKs for top commit: practicalswift: Tested ACK fa13e1b0c52738492310b6b421d8e38cb04da5b1 sipa: ACK fa13e1b0c52738492310b6b421d8e38cb04da5b1. Reviewed the code changes, and tested the 3 different test_runner.py modes (run once, merge, generate). I also tested building with the new --enable-danger-fuzz-link-all Tree-SHA512: 962ab33269ebd51810924c51266ecc62edd6ddf2fcd9a8c359ed906766f58c3f73c223f8d3cc49f2c60f0053f65e8bdd86ce9c19e673f8c2b3cd676e913f2642

2020-10-12Support for Schnorr signatures and integration in SignatureCheckers (BIP 340)Pieter Wuille
This enables the schnorrsig module in libsecp256k1, adds the relevant types and functions to src/pubkey, as well as in higher-level `SignatureChecker` classes. The (verification side of the) BIP340 test vectors is also added.
