2018-08-03Make CFX_XMLParser less permissiveRyan Harrison
Currently the parser will accept arbitrary garbage before the first element begins. This is causing issues with ClusterFuzz since it generates a lot of trash inputs which take a long time to parse inspite of being invalid. This CL adds in a check of how deep the parse is when dealing with text, and if it is at the top level scope, then only accept the beginning of the root node.

2018-04-04Decrease XML parser buffer sizeDan Sinclair
This CL decreases the m_iXMLPlaneSize in the CFX_XMLSyntaxParser from 32*1024 to 1024 bytes. This plane size is the size of the chunks we read the XML file in. The issue with having a large plane size is inside the CFX_SeekableStreamProxy::ReadString we allocate a vector of the min(planeSize, remaining_bytes). This means, we could potentially be allocating 32*1024 bytes to read in a single character. For the test in the attached bug the runtime went from 12s to 25ms.
