johnikezheng updated COMPRESS-681:
----------------------------------
Description:
I added archive properies based on the example provided in the official 7zip
code and was able to decompress it properly using the 7zip tool, but when I
decompress it using commons-compress I get the following error:
java.io.IOException: invalid property size

Example of writing to an archive file from the official 7zip source code,
7zOut.cpp:
/*
{
// It's example for per archive properies writing
WriteByte(NID::kArchiveProperties);
// you must use random 40-bit number that will identify you
// then you can use same kDeveloperID for any properties and methods
const UInt64 kDeveloperID = 0x123456789A; // change that value to real
random 40-bit number
#define GENERATE_7Z_ID(developerID, subID) (((UInt64)0x3F << 56) |
((UInt64)developerID << 16) | subID)
{
const UInt64 kSubID = 0x1; // you can use small number for subID
const UInt64 kID = GENERATE_7Z_ID(kDeveloperID, kSubID);
WriteNumber(kID);
const unsigned kPropsSize = 3; // it's example size
WriteNumber(kPropsSize);
for (unsigned i = 0; i < kPropsSize; i++)
WriteByte((Byte)(i & 0xFF));
}
{
const UInt64 kSubID = 0x2; // you can use small number for subID
const UInt64 kID = GENERATE_7Z_ID(kDeveloperID, kSubID);
WriteNumber(kID);
const unsigned kPropsSize = 5; // it's example size
WriteNumber(kPropsSize);
for (unsigned i = 0; i < kPropsSize; i++)
WriteByte((Byte)(i + 16));
}
WriteByte(NID::kEnd);
}
