This patch modifies error handling function for the XML parser provided by libxml2. Originaly only a line number and error message were logged. With this new error handler function, the user is provided with a more complex description of the parsing error. Context of the error is printed in libXML2 style and filename of the file, that caused the error is printed. Example of an parse error: 13:41:36.262: 16032: error : catchXMLError:706 : /etc/libvirt/qemu/rh_bad.xml:58: Opening and ending tag mismatch: name line 2 and domain </domain> ---------^ Context of the error gives the user hints that may help to quickly locate a corrupt xml file. fixes BZs: ---------- Bug 708735 - [RFE] Show column and line on XML parsing error https://bugzilla.redhat.com/show_bug.cgi?id=708735 Bug 726771 - libvirt does not specify problem file if persistent xml is invalid https://bugzilla.redhat.com/show_bug.cgi?id=726771
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
