This commit contains the entire btcwire repository along with several
changes needed to move all of the files into the wire directory in
order to prepare it for merging. This does NOT update btcd or any of the
other packages to use the new location as that will be done separately.
- All import paths in the old btcwire test files have been changed to the
new location
- All references to btcwire as the package name have been chagned to
wire
- The coveralls badge has been removed since it unfortunately doesn't
support coverage of sub-packages
This is ongoing work toward #214.
The hash is not displayed big endian, but rather as a byte-reversed
hash as a hexidecimal string, so document it as such.
While here, speed up the function. Some benchmarks:
BenchmarkShaHashString 2000000 996 ns/op
BenchmarkShaHashStringOld 100000 22701 ns/op
Add the word 'string' to the error string so if this is printed, it
will be clearer that it was a hash string decode that failed (as
opposed to other errors creating a ShaHash from a byte slice) and
change 'chars' to 'bytes', since the string length is measured in
bytes, not UTF-8 code points.
ok @davecgh
