The mechanism: the embracing descendant-or-self + axis traversal (also optimized to return only nodes which + can hold elements), will produce context nodes for the + inner traversal of the child axis. This way we avoid a full + node-collecting traversal of the descendant-or-self axis. + Some tests indicate that this can reduce execution time of + "//foo" to 50%. Together with the XPath object cache this + all significantly speeds up libxslt. + +Tue May 30 11:38:47 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xmlschemas.c: A warning will now be reported in the value of + the XSD attribute 'schemaLocation' does not consist of tuples + (namespace-name, document-URI).

Especially for "//foo" this will decrease dramatically + the number of created node-sets, since for each node in the + result node-set of the evaluation of descendant-or-self::node() + a new temporary node-set was created. Added node iterator + xmlXPathNextChildElement() as a tiny optimization for + child::foo. + +Mon May 29 18:06:17 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xpath.c include/libxml/xpath.h: Added an XPath object cache. + It sits on an xmlXPathContext and need to be explicitely + activated (or deactivated again) with + xmlXPathContextSetObjectCache(). The cache consists of 5 + lists for node-set, string, number, boolean and misc XPath + objects. Internally the xpath.c module will use object- + deposition and -acquisition functions which will try to reuse + as many XPath objects as possible, and fallback to normal + free/create behaviour if no cache is available or if the cache + is full. + * runsuite.c: Adjusted to deactivate the cache for XML Schema + tests if a cache-creation is turned on by default for the whole + library, e.g. for testing purposes of the cache. It is + deactivated here in order to avoid confusion of the memory leak + detection in runsuite.c. + +Wed May 24 10:54:25 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xpath.c: Removed a memcpy if xmlXPathNodeSetMerge(); it + seems we really need to walk the whole list, since those + nastly namespace nodes need to be added with + xmlXPathNodeSetDupNs(); thus a pure memcpy is not possible. + A flag on the node-set indicating if namespace nodes are in + the set would help here; this is the 3rd flag which would + be usefull with node-sets. The current flags I have in mind: + 1) Is a node-set already sorted? + This would allow for rebust and optimizable sorting + behaviour. + 2) Of what type are the nodes in the set (or of mixed type)? + This would allow for faster merging of node-sets. + 3) Are namespace nodes in the set? + This would allow to skipp all the namespace node specific + special handling. Faster node-set merging if the first + set is empty; just memcpy the set. + +Mon May 22 17:14:00 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xpath.c: Optimization of count(): eliminated sorting + (see bug #165547).

Tiny further enhancement of + xmlXPathCmpNodesExt(). Added additional checks in various code + parts to avoid calling sorting or merging functions if the + node-set(s) don't need them; i.e., if they are empty or contain + just one node. + +Fri May 19 13:16:58 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xpath.c: Optimized the comparison for non-element nodes + in xmlXPathCmpNodesExt(); the comparison is used for sorting + of node-sets. This enhancement is related to bug #165547. + There are other places where the old comparison function + xmlXPathCmpNodes() is still called, but I currently don't + know exactly what those calls are for; thus if they can be + substituted (if it makes sense) for the new function. + +Tue May 16 16:55:13 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xpath.c: Applied patch from Rob Richards, fixing a potential + memory leak in xmlXPathTryStreamCompile(), when a list of + namespaces was assigned to the XPath compilation context; + here a new namespace list was created and passed to + xmlPatterncompile(); but this list was not freed afterwards. + Additionally we avoid now in xmlXPathTryStreamCompile() to + compile the expression, if it has a colon - indicating + prefixed name tests - and no namespace list was given. The + streaming XPath mechanism needs a namespace list at + compilation time (unlike normal XPath, where we can bind + namespace names to prefixes at execution time). + * pattern.c: Enhanced to use a string dict for local-names, + ns-prefixes and and namespace-names. + Fixed xmlStreamPushInternal() not to use string-pointer + comparison if a dict is available; this won't work, since + one does not know it the given strings originate from the + same dict - and they normally don't do, since e.g. + namespaces are hold on xmlNs->href. I think this would be + worth an investigation: if we can add a @doc field to xmlNs + and put the @href in to a additionan namespace dict hold + in xmlDoc. Daniel will surely not like this idea :-) But + evaluation of tons of elements/attributes in namespaces + with xmlStrEqual() isn't the way we should go forever. + +Thu May 11 18:03:49 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xmlschemas.c: Fixed bug #341337, reported by David Grohmann. + The code expected a node (xmlNodePtr) on the info for a + non-existent default attribute, which clearly cannot be + expected, since the attribute does not exist. I can only + guess that this sneaked trying to eliminate the query + for the owner-element, which is unavoidable actually. + Note that creation of default attributes won't have an + effect if validating via SAX/XMLReader; i.e., the processor + won't fire additional start-attribute events (I'm not even + sure if Libxml2 has such a SAX-event; I think it hands them + all over in the start-element event). + +Tue May 9 21:47:58 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net> + + * xmlschemas.c: Fixed bug #341150, reported by Michael Romer. + In xmlSchemaBuildContentModelForSubstGroup(), + xmlAutomataNewOnceTrans2() was incorrectly used instead of + xmlAutomataNewTransition2() to mimic a xs:choice for + substitution-groups. + * test/schemas/subst-group-1_1.xsd + test/schemas/subst-group-1_0.xml + result/schemas/subst-group-1_0_1 + result/schemas/subst-group-1_0_1.err: Added regression test + supplied by Michael Romer for bug #341150. + +Sat May 6 11:05:24 HKT 2006 William M.

A namespace declaration is -associated with an in-memory structure and all elements or attributes within -that namespace point to it. Hence testing the namespace is a simple and fast -equality operation at the user level.</p><p>I suggest that people using libxml2 use a namespace, and declare it in the -root element of their document as the default namespace.

There is a new xml2-config script which should be used to - select the right parameters libxml2</li> - <li>Node <strong>childs</strong> field has been renamed - <strong>children</strong> so s/childs/children/g should be applied - (probability of having "childs" anywhere else is close to 0+</li> - <li>The document don't have anymore a <strong>root</strong> element it has - been replaced by <strong>children</strong> and usually you will get a - list of element here. For example a Dtd element for the internal subset - and it's declaration may be found in that list, as well as processing - instructions or comments found before or after the document root element. - Use <strong>xmlDocGetRootElement(doc)</strong> to get the root element of - a document. Alternatively if you are sure to not reference DTDs nor have - PIs or comments before or after the root element - s/->root/->children/g will probably do it.</li> - <li>The white space issue, this one is more complex, unless special case of - validating parsing, the line breaks and spaces usually used for indenting - and formatting the document content becomes significant. So they are - reported by SAX and if your using the DOM tree, corresponding nodes are - generated. Too approach can be taken: - <ol><li>lazy one, use the compatibility call - <strong>xmlKeepBlanksDefault(0)</strong> but be aware that you are - relying on a special (and possibly broken) set of heuristics of - libxml to detect ignorable blanks. Don't complain if it breaks or - make your application not 100% clean w.r.t. to it's input.</li> - <li>the Right Way: change you code to accept possibly insignificant - blanks characters, or have your tree populated with weird blank text - nodes. You can spot them using the commodity function - <strong>xmlIsBlankNode(node)</strong> returning 1 for such blank - nodes.</li> - </ol><p>Note also that with the new default the output functions don't
