2023-02-06Merge bitcoin/bitcoin#26345: refactor: modernize the implementation of uint256.*Andrew Chow
935acdcc79d1dc5ac04a83b92e5919ddbfa29329 refactor: modernize the implementation of uint256.* (pasta) Pull request description: - Constructors of uint256 to utilize Span instead of requiring a std::vector - converts m_data into a std::array - Prefers using `WIDTH` instead of `sizeof(m_data)` - make all the things constexpr - replace C style functions with c++ equivalents - memset -> std::fill This may also be replaced by std::memset, but I think that std::fill is more idiomatic of modern c++ and readable. - memcpy -> std::copy Note: In practice, implementations of std::copy avoid multiple assignments and use bulk copy functions such as std::memmove if the value type is TriviallyCopyable and the iterator types satisfy LegacyContiguousIterator. (https://en.cppreference.com/w/cpp/algorithm/copy) This could also likely be replaced by std::memcpy, but as said above, I believe the using std::copy is the more c++ way to do anything and is almost guaranteed to compile to the same asm - memcmp -> std::memcmp ACKs for top commit: achow101: ACK 935acdcc79d1dc5ac04a83b92e5919ddbfa29329 hebasto: Approach ACK 935acdcc79d1dc5ac04a83b92e5919ddbfa29329. aureleoules: reACK 935acdcc79d1dc5ac04a83b92e5919ddbfa29329 john-moffett: ACK 935acdcc79d1dc5ac04a83b92e5919ddbfa29329 stickies-v: Approach ACK 935acdcc7 Tree-SHA512: 4f1ba54ff2198eea0e505d41e73d552c84c60f6878d5c85a94a8ab57f39afc94ef8d79258e7afd01fa84ec2a99f4404bb877eecd671f65e1ee9273f3129fc650

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.

2017-09-21Remove some unused functions and methodsPieter Wuille
In the case of CKey's destructor, it seems to have been an oversight in f4d1fc259 not to delete it. At this point, it results in the move constructors/assignment operators for CKey being deleted, which may have a performance impact.

2016-11-07Get rid of nType and nVersionPieter Wuille
Remove the nType and nVersion as parameters to all serialization methods and functions. There is only one place where it's read and has an impact (in CAddress), and even there it does not impact any of the recursively invoked serializers. Instead, the few places that need nType or nVersion are changed to read it directly from the stream object, through GetType() and GetVersion() methods which are added to all stream classes.
2016-11-07Make GetSerializeSize a wrapper on top of CSizeComputerPieter Wuille
Given that in default GetSerializeSize implementations created by ADD_SERIALIZE_METHODS we're already using CSizeComputer(), get rid of the specialized GetSerializeSize methods everywhere, and just use CSizeComputer. This removes a lot of code which isn't actually used anywhere. For CCompactSize and CVarInt this actually removes a more efficient size computing algorithm, which is brought back in a later commit.
2016-05-17Use SipHash-2-4 for CCoinsCache indexPieter Wuille
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.

2013-12-25Unittests for uint256.hThomas Holenstein
Unit tests for uint256.h. The file uint160_tests.cpp is no longer needed. The ad-hoc tests which were in uint256.h are also no longer needed. The new tests achieve 100% coverage.
2013-12-25Changed Get64(.) to GetLow64()Thomas Holenstein
The function Get64(.) has a bug in case the width is not divisible by 64. Since it is only ever used as Get64(0) this simply changes it to this special case. Additionally, an assert is added, and a cast to prevent a compiler error.
2013-11-10Cleanup code using forward declarations.Brandon Dahler
Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.
