In order to support generation of unified addresses, it needs
to be possible for the code generating a unified address to search
the space of Sapling diversifiers to obtain a valid diversifier.
Historically, invalid diviersifiers were simply skipped, so we retain
this behavior when obtaining a Sapling address from the legacy HD seed.
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.
Zcash: Propagate CCoinsKeyHasher -> SaltedTxidHasher changes to where
we've used CCoinsKeyHasher outside of its original scope.
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.
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.
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.
- Update comments in checkpoints to be doxygen compatible
- Update comments in checkqueue to be doxygen compatible
- Update coins to be doxygen compatible
- Fix comment typo in crypter.h
- Update licenses/copyright dates
Closes#5325#5184#5183#5182
- ensures a consistent usage in header files
- also add a blank line after the copyright header where missing
- also remove orphan new-lines at the end of some files
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.
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.
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.
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.

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".
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.
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.
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.
