* xmlregexp.c:
(xmlFAParseCharRange): Only advance to the next character if
there is no error. Advancing to the next character in case of
an error while parsing regexp leads to an out of bounds access.
As reported by Sven <sven@e7o.de>:
The following pattern will cause a segmentation fault in my
Apache (using PHP5 to validate a XML against a XSD):
<xs:pattern value="(.*)|"/>
Fix a cascade of error handling failures which led to the
crash in that scenario.
* xmlregexp.c: other fixes in 2.7.4 raised this internal error
when comparing ranges, this affects among others detection of
the determinism
* test/relaxng/libvirt* result/relaxng/libvirt*: add a test case
based on libvirt schemas and tests
* SAX2.c dict.c error.c hash.c nanohttp.c parser.c python/libxml.c
relaxng.c runtest.c tree.c valid.c xinclude.c xmlregexp.c xmlsave.c
xmlschemas.c xpath.c xpointer.c: mostly removing unneded affectations,
but this led to a few real bugs and some part not yet understood
(relaxng/interleave)
* HTMLparser.c c14n.c debugXML.c entities.c nanohttp.c parser.c
testC14N.c uri.c xmlcatalog.c xmllint.c xmlregexp.c xpath.c:
fix unused variables, or unneeded increments as well as a couple
of space issues
* runtest.c: check for NULL before calling unlink()
* relaxng.c xmlregexp.c: a subtle problem when checking for compileable
content model, if using the same elements in cases of choices. Handled
by adding a special flag to the regexp compilation to detect
transitions with different atoms using same strings.
* test/relaxng/492317* result/relaxng/492317*: add the test to the
regression suite
* xmlregexp.c: xmlFAComputesDeterminism was bugged as it removed as
coalesced transitions on with sane source destination and atoms but
not looking at counters
* Makefile.am: add the testchar to 'make check'
* xmlschemas.c: Volker Grabsch pointed out a typo
* xmlregexp.c: production [19] from XML Schemas regexps were a
mistake removed in version REC-xmlschema-2-20041028, Volker Grabsch
provided a patch to remove it
* test/schemas/regexp-char-ref_0.xml test/schemas/regexp-char-ref_0.xsd
test/schemas/regexp-char-ref_1.xsd result/schemas/regexp-char-ref_0_0
result/schemas/regexp-char-ref_1_0: Volker Grabsch also provided
regession tests for this

svn path=/trunk/; revision=3776
* xmlregexp.c: apply patch from Andrew Tosh to fix behaviour
when '.' is used in a posCharGroup
* test/schemas/poschargrp0_0.* result/schemas/poschargrp0_0_0*:
added the test to the regression suite
Daniel
svn path=/trunk/; revision=3687
* xmlregexp.c: another nasty regexp case fixed.
* test/regexp/ranges2 result/regexp/ranges2: added to regression
suite
Daniel
svn path=/trunk/; revision=3658
* nanohttp.c: Enhanced to include port number (if not == 80) on the
"Header:" URL (bug #469681).
* xmlregexp.c: Fixed a typo causing a warning message.
svn path=/trunk/; revision=3657
* xmlregexp.c: try to fix for the nth time the automata generation
in case of complex ranges. I suppose that time it is actually okay
Daniel
svn path=/trunk/; revision=3650
* xstc/Makefile.am doc/examples/Makefile.am Makefile.am: applied
patch from Richard Jones to for the silent flag on valgrind
when doing "make valgrind"
* xmlregexp.c: raise a regexp error when '\' is misused to escape
a standard character.
Daniel
svn path=/trunk/; revision=3606
* xmlregexp.c: fixed problem with 0x2d in Char Range (bug #420596)
* test/regexp/bug420596, result/regexp/bug420596: added regression
test for this
svn path=/trunk/; revision=3594
* tree.c: applied documentation patches from Markus Keim
* xmlregexp.c: fixed one bug and added a couple of optimisations
while working on bug #362989
Daniel
* xmlregexp.c: applied patch from Youri Golovanov fixing bug
#316338 and adding a couple of optimizations in the regexp
compilation engine.
* test/regexp/bug316338 result/regexp/bug316338: added regression
tests based on the examples provided in the bug report.
Daniel
* runtest.c schematron.c testAutomata.c tree.c valid.c xinclude.c
xmlcatalog.c xmlreader.c xmlregexp.c xpath.c: end of first
pass on coverity reports.
Daniel
* xmlsave.c xmlIO.c include/libxml/xmlIO.h include/libxml/xmlsave.h:
applied patch from Geert Jansen to implement the save function to
a xmlBuffer, and a bit of cleanup.
Daniel
* xmlregexp.c: fix bug #319897, problem with counted atoms
when the transition itself is counted too
* result/regexp/hard test/regexp/hard: augmented the regression
tests with the problem exposed.
Daniel
* valid.c xmlregexp.c include/libxml/valid.h
include/libxml/xmlregexp.h: avoid function parameters names 'list'
as this seems to give troubles with VC6 and stl as reported by
Samuel Diaz Garcia.
Daniel
* runtest.c: removed the error message
* relaxng.c xmlschemas.c: removed 2 instability warnings from function
documentation
* include/libxml/schemasInternals.h: changed warning about API stability
* xmlregexp.c: trying to improve runtime execution of non-deterministic
regexps and automata. Not fully finished but should be way better.
Daniel
* xmlregexp.c: seems a test to avoid duplicate transition is
really needed at all times. Luka Por gave an example hitting
this. Changed back the internal API.
Daniel
* xmlregexp.c: detect combinatory explosion and return with
a runtime error in those case, c.f. #316338 though maybe we
should not see such an explosion with that specific regexp,
more checking needs to be done.
Daniel
* elfgcchack.h testapi.c doc/*: regenerated
* schematron.c: fixed a compilation problem
* xmlregexp.c include/libxml/xmlregexp.h: some cleanups and one bug fix
* result/expr/base: slightly changes the number of Cons.
Daniel
* testRegexp.c xmlregexp.c include/libxml/xmlregexp.h: exported
xmlExpExpDerive(), added it to the testRegexp command line
tool when providing multiple expressions.
Daniel
* valid.c: fixed an uninitialized variable
* xmlregexp.c include/libxml/xmlregexp.h: extended the API to
add the parser, serializer and some debugging
* include/libxml/xmlversion.h.in: made the new support compiled
by default if Schemas is included
* testRegexp.c: cleanup and integration of the first part of the
new code with a special switch
* xmllint.c: show up Expr in --version if compiled in
* include/libxml/tree.h: moved the xmlBuffer definition up
Daniel
