When creating XML_XINCLUDE_START nodes, the children of the original
xi:include node must be freed, otherwise fallback content is copied
twice, doubling runtime and memory consumption for each nested
xi:fallback/xi:include pair.
Found with libFuzzer.
xmlXIncludeDoProcess would follow the siblings of the tree root and
also expand these nodes. When using an XML reader, this could lead to
siblings of the current node being expanded without having been parsed
completely.
The file input callbacks try to read from stdin if "-" is passed as URL.
This should never be done when loading indirect resources like external
entities or XIncludes. Unfortunately, the stdin substitution happens
deep inside the IO code, so we simply replace "-" with "./-" in specific
locations.
This issue also affects other users of the library like libxslt.
Ideally, stdin should only be substituted on explicit request. But more
intrusive changes could break existing code.
Closes#90 and #102.
Make sure that all parameters and return values of hash callback
functions exactly match the callback function type. This is required
to pass clang's Control Flow Integrity checks and to allow compilation
to asm.js with Emscripten.
Fixes bug 784861.

When you xinclude a text file, reading portions (by 4000 bytes) of the
buffer incorrectly handled the situation when the end comes across
portions of the bytes in a multibyte character.

of the xml:base properly (bug 146988)
* xinclude.c: some further enhancement to take care of
xml:base for XPointer elements (bug 143886). Also fixed

* xinclude.c: changed the handling of ranges to use the above new
facility. Fixes Bug 134268.

is encountered, it will log it and not crash (bug 135713)

* Makefile.am: run the doc/examples regression tests as part of
make tests
* xpath.c include/libxml/xpath.h: added xmlXPathCtxtCompile() to
compile an XPath expression within a context, currently the goal
is to be able to reuse the XSLT stylesheet dictionnary, but this
opens the door to others possible optimizations.
* dict.c include/libxml/dict.h: added xmlDictCreateSub() which allows
to build a new dictionnary based on another read-only dictionnary.

the XInclude level, raise a warning if the old one is found,
and some cleanup
Daniel

* include/libxml/xmlerror.h: added XInclude errors
Daniel
* DOCBparser.c globals.c include/libxml/xmlmemory.h: get rid of
some compilation warnings.
* xinclude.c: fix the performance problem reported by Kevin Ruscoe
plus some cleanup and better error reporting.
Daniel

by Bernd Kuemmerlen

* *.c *.h libxml files: moved to libxml directory - this allow
simplify automake/autoconf. Now isn't neccessary hack on
am/ac level for make and remove libxml symlink (modified for this
also configure.in and main Makefile.am). Now automake abilities
are used in best way (like in many other projects with libraries).
* include/win32config.h: moved to libxml directory (now include
directory isn't neccessary).
* Makefile.am, examples/Makefile.am, libxml/Makefile.am:
added empty DEFS and in INCLUDES rest only -I$(top_builddir) -
this allow minimize parameters count passed to libtool script
(now compilation is also slyghtly more quiet).
* configure.in: simplifies libzdetestion - prepare separated
variables for keep libz name and path to libz header files isn't
realy neccessary (if someone have libz installed in non standard
prefix path to header files ald library can be passed as:
$ CFALGS="-I</libz.h/path>" LDFLAGS="-L</libz/path>" ./configure
* autogen.sh: check now for libxml/entities.h.
After above building libxml pass correctly and also pass
"make install DESTDIR=</install/prefix>" from tar ball generated by
"make dist". Seems ac/am reorganization is finished. This changes
not touches any other things on *.{c,h} files level.
