[Tarantool-patches] [PATCH] msgpack: print mp_exp type as signed integer

[Ilya Kosarev]

MsgPack extension types allow applications to define
application-specific types. They consist of an 8-bit signed integer and
a byte array where the integer represents a kind of types and the byte
array represents data. Types from 0 to 127 are application-specific
types and types from -128 to -1 are reserved for predefined types.
However, extension types were printed as unsigned integers. Now it is
fixed and extension types are being printed in a correct way as signed
integers. Also the typo in word "Unsupported" was fixed. According test
case is introduced.

Closes #5016

[Tarantool-patches] [PATCH] msgpack: print mp_exp type as signed integer

[Ilya Kosarev]

MsgPack extension types allow applications to define
application-specific types. They consist of an 8-bit signed integer and
a byte array where the integer represents a kind of types and the byte
array represents data. Types from 0 to 127 are application-specific
types and types from -128 to -1 are reserved for predefined types.
However, extension types were printed as unsigned integers. Now it is
fixed and extension types are being printed in a correct way as signed
integers. Also the typo in word "Unsupported" was fixed. According test
case is introduced.
