2020-10-12Add txrequest modulePieter Wuille
This adds a new module (unused for now) which defines TxRequestTracker, a data structure that maintains all information about transaction requests, and coordinates requests.
2020-09-28uint256: Update constructors to c++11, make ONE staticAnthony Towns
Replace the memset with C++11 value/aggregate initialisation of the m_data array, which still ensures the unspecified values end up as zero-initialised. This then allows changing UINT256_ONE() from dynamically allocating an object, to a simpler referencing a static allocation.
2020-08-06refactor: Make HexStr take a spanWladimir J. van der Laan
Make HexStr take a span of bytes, instead of an awkward pair of templated iterators.

2019-07-03Merge #14734: fix an undefined behavior in uint::SetHexWladimir J. van der Laan
0f459d868d85053f1cc066ea9099793f88cbd655 fix an undefined behavior in uint::SetHex (Kaz Wesley) Pull request description: Decrementing psz beyond the beginning of the string is UB, even though the out-of-bounds pointer is never dereferenced. I don't think any clang sanitizer covers this, so I don't see any way a test could catch the original behavior. ACKs for top commit: promag: utACK 0f459d8. l2a5b1: utACK 0f459d868d85053f1cc066ea9099793f88cbd655 Tree-SHA512: 388223254ea6e955f643d2ebdf74d15a3d494e9f0597d9f05987ebb708d7a1cc06ce64bd25d447d75b5f5561bdae9630dcf25adb7bd75f7a382298b95d127162
2019-01-10util: Make ToLower and ToUpper take a charWladimir J. van der Laan
Unfortunately, `std::string` elements are (bare) chars. As these are the most likely type to be passed to these functions, make them use char instead of unsigned char. This avoids some casts.

This is ~1.7x slower than the Lookup3-of-Xor-with-salt construct we were using before, but it is a primitive designed for exactly this.

2014-08-26Split up util.cpp/hWladimir J. van der Laan
Split up util.cpp/h into: - string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach) - money utilities (parsesmoney, formatmoney) - time utilities (gettime*, sleep, format date): - and the rest (logging, argument parsing, config file parsing) The latter is basically the environment and OS handling, and is stripped of all utility functions, so we may want to rename it to something else than util.cpp/h for clarity (Matt suggested osinterface). Breaks dependency of sha256.cpp on all the things pulled in by util.
