Fix a regression caused by commit 39fbfb4f. If xmlTextReaderReadOuterXml
is called on a pristine xmlReader, the current node is NULL and must not
be dereferenced. Move the call to xmlTextReaderExpand to the start of
the function to make sure that we have a valid node.
Fixes#43.
In error cases, there might still be elements in the vstate table.
Since vstateVPop in valid.c is private, we have to pop the elements
with xmlValidatePopElement. This inspects nodes of the document, so
the reader doc must be freed after the clearing the vstate table.
Found by OSS-Fuzz.
Otherwise the encoding of the document is ignored and non-ASCII
characters are serialized as numeric references even if the encoding
is specified as UTF-8.
This fixes the traversal of parent nodes using xmlTextReaderNext()
when the reader is based on a preparsed document (created using
xmlReaderWalker(doc)).
Without this fix the parser will abort even though there are parent
nodes it should traverse to, if it is not currently on an element or
attribute node. This is incorrect, since it can be for example on a
text node when it needs to enter backtracking.
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.
One of the operation on the reader could resolve entities
leading to the classic expansion issue. Make sure the
buffer used for xmlreader operation is bounded.
Introduce a new allocation type for the buffers for this effect.
Things now work correctly at the xmllint level:
thinkpad:~/XML -> xmllint --sax --noout --schema test_schema.xsd
test_xml.xml
test_xml.xml:72721: Schemas validity error : Element 'level1': Missing
child element(s). Expected is ( level2 ).
test_xml.xml fails to validate
thinkpad:~/XML -> xmllint --stream --schema test_schema.xsd test_xml.xml
test_xml.xml:72721: Schemas validity error : Element 'level1': Missing
child element(s). Expected is ( level2 ).
test_xml.xml fails to validate
thinkpad:~/XML ->
* error.c: fix a corner case of not reporting lines when we should
* include/libxml/xmlschemas.h doc/symbols.xml: had to add new entry
points to set the filename on a validation context and a locator
callback used to fetch the line and file from the context
* xmlschemas.c: add the new entry points xmlSchemaValidateSetFilename()
and xmlSchemaValidateSetLocator(), plus make sure the error reporting
routine gets the information if available. Add a locator for SAX.
* xmlreader.c: add and plug a locator for readers.
This was scattered in a number of modules, xmlParserInputPtr
have usually their base, cur and end pointer set from an
xmlBuf used as input.
* buf.c buf.h: add a new function implementing this setup
* parser.c HTMLparser.c catalog.c parserInternals.c xmlreader.c
use the new function instead of digging into the buffer in
all those modules

I use xmlTextReader to parse failed that might be incomplete. These files are
the beginning of a well-formed file, but the end is missing so the file as a
whole is not well-formed.
The problem is that xmlTextReader starts returning errors when it encounters
the early EOF, even though I haven't finished reading all of the valid data in
the file. It would be helpful if xmlTextReader kept working until the very
end.

In case of error on an IO creation input the given context
is terminated with the given close function, except if the
error happened in xmlParserInputBufferCreateIO. This can
lead to a resource leak which is fixed by this patch.
Since there is xmlTextReaderSchemaValidateCtxt() it seems like there
should be an equivalent RelaxNG function. The attached patch adds it.
The code is essentially the same as Schema implementation, but I'm
uncertain as to how to add things to the documentation and test suite:
there seems to be a lot of auto-generation going on.
* configure.in Makefile.am: add an --with-coverage configure option
and a 'make cov' target based on gcc profiling and the lcov
tool. Currently at 68.9% coverage out of 'make check' and
runsuite executions.
* xmlreader.c: remove warnings due to C++ comments

svn path=/trunk/; revision=3780
* xmlreader.c: applied patch from Aswin to fix tree skipping
* include/libxml/entities.h entities.c: fixed a comment and
added a new xmlNewEntity() entry point
* runtest.c: be less verbose
* tree.c: space and tabs cleanups
daniel
svn path=/trunk/; revision=3774
* parser.c: added a GROW when parsing complex comments (bug #405666)
* gentest.py, testapi.c: added a hack to prevent destruction of any
param with 'destroy' in it's description (i.e. param destroyed by
the routine under test, so shouldn't be destroyed by testapi)
* xmlreader.c: added freeing of 'input' param even on error
svn path=/trunk/; revision=3579
* xmlreader.c: fix xmlTextReaderSetup() description
* test/relaxng/empty1.rng test/relaxng/comps_0.xml
test/relaxng/empty1_0.xml test/relaxng/comps.rng
test/relaxng/empty0.rng test/relaxng/empty0_0.xml
test/relaxng/empty1_1.xml: tests which were apparently
never commited to CVS

* runtest.c schematron.c testAutomata.c tree.c valid.c xinclude.c
xmlcatalog.c xmlreader.c xmlregexp.c xpath.c: end of first
