John Snelson updated XERCESC-1805:
----------------------------------
Attachment: xercesc_3_0_content_type_patch
This patch implements the BinInputStream::getContentType() method for the
socket, winsock and libcurl net accessors.
In addition, the common code has been extracted from the UnixHTTPURLInputStream
(socket) and BinHTTPURLInputStream (winsock), cleaned up, bug fixed and put
into two new files -
src/xercesc/util/BinHTTPInputStream.hpp
src/xercesc/util/BinHTTPInputStream.cpp
These files have been added to src/Makefile.am, but not to any project files.
This patch has been tested on Ubuntu using libcurl and socket net accessors,
and on Windows XP MingW using winsock.

> Key: XERCESC-1805
> URL: https://issues.apache.org/jira/browse/XERCESC-1805
> Project: Xerces-C++
> Issue Type: Improvement
> Components: Miscellaneous
> Affects Versions: 3.0.0
> Reporter: John Snelson
> Fix For: 3.0.0

> Attachments: xercesc_3_0_content_type_patch

>
> A lot of algorithms need access to the HTTP "Content-Type" header, to decide
> how to parse a file, or what encoding it is in - for instance see XSLT 2.0's
> unparsed-text() function:
> http://www.w3.org/TR/xslt20/#unparsed-text
> We should add a method, BinInputStream::getContentType(), and implement it in
> the HTTP input stream implementations. The method should return 0 when the
> content type is not available, like for file input streams.
> In addition, the socket and WinSock HTTP InputStream implementations have a
> number of problems:
> 1) They used fixed buffers which can result in buffer overflow.
> 2) They needlessly duplicate a whole load of code that could be shared.
> 3) They transcode to the local code page rather than "ISO8859-1".
