Subject [jira] [Commented] (IGNITE-3140) C++: UTF-16 surrogate symbols are not serialized properly
Date Mon, 16 May 2016 17:47:12 GMT

Denis Magda commented on IGNITE-3140:
-------------------------------------

Igor,

In case of heterogeneous cluster (Java and C++ nodes) C++ side won't be able to properly deserialize
surrogate symbols from a String serialized on Java side if the new algo (from IGNITE-3098)
is used. This is the reason why we should rewrite strings serialization on logic on C++ side
as well.

> There is an issue with serialization of a surrogate symbol with {{BinaryMarshaller}}.
On Java side String's serialization logic was improved to support all the cases. Refer to
IGNITE-3098.
> C++ serialization logic has to be updated as well. Please refer to the algorithm located
in ignite-3098 branch in the following places:
> - {{BinaryUtils.utf8BytesToStr}} - serialization
> - {{BinaryUtils.strToUtf8Bytes}} - deserialization
> - {{IgniteSystemProperties.IGNITE_BINARY_MARSHALLER_USE_STRING_SERIALIZATION_VER_2}}
controls which version of serialization logic to use (old or new).
