Hello!
I add a data parket field in the data.cpp ,such as
template<encoding::Tag TAG>
size_t
Data::wireEncode(EncodingImpl<TAG>& encoder, bool unsignedPortion/* = false*/) const
{
size_t totalLength = 0;
// Data ::= DATA-TLV TLV-LENGTH
// Name
// MetaInfo
// Content
// Signature
// Digest
// (reverse encoding)
if (!unsignedPortion && !m_signature)
{
BOOST_THROW_EXCEPTION(Error("Requested wire format, but data packet has not been signed yet"));
}
// Digest
totalLength += encoder.prependBlock(getDigest());
if (!unsignedPortion)
{
// SignatureValue
totalLength += encoder.prependBlock(m_signature.getValue());
}
// SignatureInfo
totalLength += encoder.prependBlock(m_signature.getInfo());
// Content
totalLength += encoder.prependBlock(getContent());
// MetaInfo
totalLength += getMetaInfo().wireEncode(encoder);
// Name
totalLength += getName().wireEncode(encoder);
if (!unsignedPortion)
{
totalLength += encoder.prependVarNumber(totalLength);
totalLength += encoder.prependVarNumber(tlv::Data);
}
return totalLength;
}
const Block&
Data::getDigest() const
{
if (m_fullName1.empty())
m_fullName1 = makeEmptyBlock(tlv::Digest);
if (!m_fullName1.hasWire())
m_fullName1.encode();
return m_fullName1;
}
Data&
Data::setDigest(const Block& fullname)
{
onChanged();
if (fullname.type() == tlv::Digest)
m_fullName1 = fullname;
else {
m_fullName1 = Block(tlv::Digest, fullname);
}
return *this;
}
Data&
Data::setDigest(const uint8_t* fullname, size_t fullnameLength)
{
onChanged();
m_fullName1 = makeBinaryBlock(tlv::Digest, fullname, fullnameLength);
return *this;
}
But, program always shows that "terminated with signal SIGSEGV",I don't konw how to solve it.
