Hello, we are trying to use infinispan with Java and cpp client, and got an issue with versioned value.
We are using Infinispan 6.0.2.Final configured with JBoss AS7.
The c++ versioned value feature is not working when the server is configured as clustered mode.
Observation :
- with standalone mode :
version at server : 1 (I checked the version value by adding some debug code to the server-core module)
version at client : 1
replaceWithVersion result : success
- with clustered mode :
version at server : 4294969598 (I checked the version value by adding some debug code to the server-core module)
This is because the first 4bytes of the version is used to store cluster related information, according to the javadoc,
version at client : 1
The first 4 bytes is ignored.
Our debugging result :
There was a type mismatch bug in the C++ connector.
int64_t AbstractTransport::readLong()
{
hrbytes longBytes;
readBytes(longBytes, 8);
long result = 0; <-- 4bytes, should be 8bytes datatype which is int64_t
for (int i = 0; i < 8 ; i++) {
result <<= 8;
result ^= (int64_t) *(longBytes.bytes()+i) & 0xFF;
}
return result;
}
How we resolved this issue :
We just changed the declaration of result variable as follows.
int64_t result = 0; <-- now it is 8bytes
We are now having not problem with cpp versioned value.
If this is a real bug, please someone patch the code.
