serialization problems with specific sequence of chars

[mcaramma]

OSerializationException is raised when calling record_create() with specific strings.

setup:

• Debian GNU/Linux 8.1 (Jessie)
• virtualenv
• pip install pyorient --upgrade
• created new database "test"
• created new class "MyModel" which get clusterID = 12

Code examples generating the exception:

= code example 1

import pyorient
client = pyorient.OrientDB("localhost", 2424)
client.db_open("test", "admin", "admin" )
data = {'sku': '""">'}
rec = {'@MyModel': data}
client.record_create(12, rec)

A few examples of strings that generate issues during serialization are:

• """>
• ">""
• " fdas " fda " fdsaf > fdsa
• " > fdas " fda "
• " > fdas " fda "
• " > fdas " fda > "

Many more variants can be used.
