2018-04-24Remove CFX_BlockBufferchromium/3406Dan Sinclair
This CL removes the usage of CFX_BlockBuffer from CFX_XMLParser. The block buffer has been replaced by a vector which is emptied out after the characters are removed. This should use less memory when parsing XML as the block buffer was previously storing all text characters seen in the file.

2018-04-09Make pdfium::span<> be based off of UnownedPtr<>.Tom Sepez
Because we can get the lifetime check for free if we do this. This requires adding some "constexpr/noexcept" to UnownedPtr to make the types line up with what span.h requires.

2018-04-06Add span.h from chromium base.chromium/3392Tom Sepez
Allows indexing with better bounds-checking to occur. Some small modifications are required to deal with PDFium being intentionally held at C++11 compliance, not C++14. Use in one place as check on correctness.

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.
