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.

Make util phexdigit array reusable
2013-10-27Make util phexdigit array reusableOlivier Langlois
class template base_uint had its own private lookup table. This is saving 256 bytes per instantiation. The result is not spectacular as bitcoin-qt has only shrinked of about 1Kb but it is still valid improvement. Also, I have replaced a for loop with a memset() call. Made CBigNum::SetHex() use the new HexDigit() function. Signed-off-by: Olivier Langlois <olivier@olivierlanglois.net>

2013-05-07Specified base_uint component sizeWilliam Yager
A base_uint used to be made of an array of unsigned ints. This works fine on most platforms, but might not work on certain present or future platforms. The code breaks if an unsigned int is 16 or 64 bits, so it's important to be specific. Also changed "u" to "you".
2013-04-12Use a uint256 for bnChainWorkPieter Wuille
Every block index entry currently requires a separately-allocated CBigNum. By replacing them with uint256, it's just 32 bytes extra in CBlockIndex itself. This should save us a few megabytes in RAM, and less allocation overhead.

Also const correctness for lookup tables in hex functions throughout the code.
2012-05-18Update License in File HeadersFordy
I originally created a pull to replace the "COPYING" in crypter.cpp and crypter.h, but it turned out that COPYING was actually the correct file.

2012-04-18Fix bugs on 'unsigned char' platforms.Dwayne C. Litzenberger
In ISO C++, the signedness of 'char' is undefined. On some platforms (e.g. ARM), 'char' is an unsigned type, but some of the code relies on 'char' being signed (as it is on x86). This is indicated by compiler warnings like this: bignum.h: In constructor 'CBigNum::CBigNum(char)': bignum.h:81:59: warning: comparison is always true due to limited range of data type [-Wtype-limits] util.cpp: In function 'bool IsHex(const string&)': util.cpp:427:28: warning: comparison is always false due to limited range of data type [-Wtype-limits] In particular, IsHex erroneously returned true regardless of the input characters, as long as the length of the string was a positive multiple of 2. Note: For testing, it's possible using GCC to force char to be unsigned by adding the -funsigned-char parameter to xCXXFLAGS.
2012-04-17Further reduce header dependenciesPieter Wuille
This commit removes the dependency of serialize.h on PROTOCOL_VERSION, and makes this parameter required instead of implicit. This is much saner, as it makes the places where changing a version number can have an influence obvious.

foo.size() typically returns an unsigned integral type; make loop variables match those types' signedness.

2012-02-24CAddrMan: stochastic address managerPieter Wuille
Design goals: * Only keep a limited number of addresses around, so that addr.dat does not grow without bound. * Keep the address tables in-memory, and occasionally write the table to addr.dat. * Make sure no (localized) attacker can fill the entire table with his nodes/addresses. See comments in addrman.h for more detailed information.

2012-01-06Network stack refactorPieter Wuille
This introduces CNetAddr and CService, respectively wrapping an (IPv6) IP address and an IP+port combination. This functionality used to be part of CAddress, which also contains network flags and connection attempt information. These extra fields are however not always necessary. These classes, along with logic for creating connections and doing name lookups, are moved to netbase.{h,cpp}, which does not depend on headers.h. Furthermore, CNetAddr is mostly IPv6-ready, though IPv6 functionality is not yet enabled for the application itself.
