Planio Saxon - Bug #6379 (New): Default implementation of fn:deep-equalhttps://saxonica.plan.io/issues/63792024-03-27T11:18:36ZNorm Tovey-Walsh
<p>I happened to trace my way through a call to deep equal in Saxon HE 12.4 and I was a little bit surprised to find that it's using the <code>DeepEqual40</code> implementation. I wonder if that was intentional...</p> Saxon - Support #6376 (In Progress): Xslt Map Memory Footprinthttps://saxonica.plan.io/issues/63762024-03-22T14:42:37Zfouad MOUTASSIM
<p>Hello,</p>
<p>We are using Saxonica 10.4 with Java and have noticed that it consumes a lot of memory when running.
For example, when processing a payload of 100MB, the map consumes 1.3GB, which causes memory issues in our application.</p>
<p>We kindly request your support in addressing this matter.</p>
<p>Please find attached the following elements:</p>
<p>The XSLT map.
The Java class.
The input payload.
Thank you in advance for your support.</p> SaxonJS - Feature #6375 (New): Support popular DOM implementationshttps://saxonica.plan.io/issues/63752024-03-19T14:58:59ZMichael Kaymike@saxonica.com
<p>The "barrier to entry" for SaxonJS would be reduced if we were able to promote it as an API for executing XPath 3.1 against popular DOM implementations -- xmldom, jsdom, slimdom, ...</p>
<p>I don't think there's any fundamental barrier to supporting external DOM implementations, it just needs testing.</p> SaxonJS - Bug #6374 (New): saxon.compile removed in 2.6+?https://saxonica.plan.io/issues/63742024-03-19T09:54:05ZJai B
<p>Hi,</p>
<p>I've always used the <code>saxon.compile</code> function to generate sef files in code. I know it's undocumented but IIRC it was shown in the command line docs or something.</p>
<p>Basically I cache the compiled sef so I don't have to recompile everytime I want to do a transform and I don't want to pre-transform my XSLT files on the command line, nor do I have any desire to use the Java version for that part, the JS compiler has worked amazingly!</p>
<p>My web app does server side transformations with node; anytime it sees the XSLT change, it runs a compile to generate and cache a new sef to use for subsequent transformations. I can't cache the result of the transformation either since the data is dynamic, of course.</p>
<p>Perhaps I'm missing something or missing some changes, but this has worked awesome for years and only just noticed things breaking when redeploying some stuff and npm updating to 2.6.0 and getting an error that the function doesn't exist.</p>
<p>When I was initially implementing this, I know I spent a fair bit of time trying to figure this part out and ensure I was doing things right; I think I scoped the code that generates the sef on command line to find the function in the first place and was surprised it wasn't actually documented/available anyway.</p>
<p>Thanks again for SaxonJS!</p> SaxonC - Bug #6372 (In Progress): Unable to parse Windows-1252 encoded XML files on Linuxhttps://saxonica.plan.io/issues/63722024-03-15T13:57:04ZMatt Patterson

</blockquote> Saxon - Support #6369 (New): Serialization problem of XQuery result using Saxon 12.3https://saxonica.plan.io/issues/63692024-03-06T10:36:34ZRadu Coravuradu_coravu@sync.ro
<p>We run this XQuery as a transformation scenario in Oxygen:</p>
<pre><code>declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization";
declare option output:method 'text';
declare option output:item-separator ', ';
let $xml:=<xml><element>text1</element><element>text2</element></xml> return $xml/element/string()
</code></pre>
<p>and we get as result:</p>
<pre><code>text1, , text2
</code></pre>
<p>Notice the two commas ", " between the two items.</p>
<p>To serialize we create a tree receiver something like:</p>
<pre><code> SerializerFactory sf = this.queryTransformer.getConfiguration().getSerializerFactory();
PipelineConfiguration pipe = this.queryTransformer.getConfiguration().makePipelineConfiguration();
SerializationProperties props = new SerializationProperties(queryTransformer.getOutputProperties());
Receiver receiver = sf.getReceiver(new StreamResult(sw), props, pipe);
tr = new TreeReceiver(receiver)..
</code></pre>
<p>The "net.sf.saxon.event.SequenceReceiver#decompose" is called for each item "text1" and "text2". The stack trace is something like:</p>
<pre><code> at net.sf.saxon.str.UnicodeWriterToWriter.write(UnicodeWriterToWriter.java:36)
at net.sf.saxon.serialize.TEXTEmitter.characters(TEXTEmitter.java:104)
at net.sf.saxon.event.ProxyReceiver.characters(ProxyReceiver.java:158)
at net.sf.saxon.event.SequenceNormalizer.characters(SequenceNormalizer.java:99)
at net.sf.saxon.event.SequenceNormalizerWithItemSeparator.sep(SequenceNormalizerWithItemSeparator.java:135)
at net.sf.saxon.event.SequenceNormalizerWithItemSeparator.characters(SequenceNormalizerWithItemSeparator.java:75)
at net.sf.saxon.event.TreeReceiver.characters(TreeReceiver.java:176)
at net.sf.saxon.event.SequenceReceiver.decompose(SequenceReceiver.java:178)
</code></pre>
<p>For "text2" which is ATOMIC the code in "net.sf.saxon.event.SequenceReceiver.decompose(Item, Location, int)" does this:</p>
<pre><code> protected void decompose(Item item, Location locationId, int copyNamespaces) throws XPathException {
if (item != null) {
switch (item.getGenre()) {
case ATOMIC:
case EXTERNAL:
if (previousAtomic) {
characters(StringConstants.SINGLE_SPACE, locationId, ReceiverOption.NONE);
}
characters(item.getUnicodeStringValue(), locationId, ReceiverOption.NONE);
</code></pre>
<p>It calls "characters(StringConstants.SINGLE_SPACE, locationId, ReceiverOption.NONE);" which adds a space and a comma before the space as the method "net.sf.saxon.event.SequenceNormalizerWithItemSeparator.characters(UnicodeString, Location, int)" always calls sep().
And then it calls:</p>
<pre><code>characters(item.getUnicodeStringValue(), locationId, ReceiverOption.NONE);
</code></pre>
<p>which again adds a comma before the value. So we get two commas before the actual value is printed.</p> Saxon - Bug #6361 (In Progress): XPath parser continously looping to find Xpath function library ...https://saxonica.plan.io/issues/63612024-02-27T09:32:05ZManikandan S

<p><code>ixsl:schedule-action</code> supports <code>@document</code> and <code>@http-request</code>. Both approaches have their advantages.
For <code>@schedule-action</code>:</p>
<blockquote>
<p>The called template can access the documents using the <code>doc()</code>, <code>document()</code>, <code>doc-available()</code>, <code>json-doc()</code>, <code>unparsed-text()</code>, <code>unparsed-text-available()</code>, and <code>unparsed-text-lines()</code> functions as appropriate (the documents will be found in a local cache and will not involve another request to the server).</p>
</blockquote>
<p>For <code>@http-request</code> it's the possibility to fully specify the HTTP request headers. That's what I have been using so har</p>
<p>The problem is that the approaches cannot be combined. In other words, it is not possible to specify HTTP request headers, load documents asynchronously <em>and</em> pass them to templates that use document()
What could be the solution to this?</p>
<p>Adding more options to <code>ixsl:schedule-action</code> seems like it would overload the instruction too much. I'm thinking a better idea could be decoupling the HTTP client functionality from the document caching functionality. That could be achieved using a new instruction that caches a document node under the specified URI, thus making it available for <code>document()</code> calls.</p>
<p>For example:</p>
<pre><code class="xml syntaxhl" data-language="xml"> <span class="nt"><xsl:variable</span> <span class="na">name=</span><span class="s">"href"</span> <span class="na">select=</span><span class="s">"http://example.com/doc.xml"</span> <span class="na">as=</span><span class="s">"xs:string"</span><span class="nt">/></span>

<p>Thanks to silfer1200 and Martin Honnen for reporting.</p>
<p>If you try to pass a filename containing a unicode char with a multi-byte representation in UTF-8 into Saxon C's python layer some weird mangling happens and it looks like the string gets decomposed to a bytestream and then recomposed into a string with each byte considered a complete character.</p>

<p>This should fail because the <code>$callback</code> function requires an xs:integer but the supplied value (the result of the integer division) is an xs:decimal.</p>
<p>What is supposed to happen according to the spec is that the supplied function (which accepts an x:decimal) is coerced to the required type (which does not). The means that the function actually supplied to the $callback parameter is effectively:</p>
<pre><code>function($d1 as xs:integer) as xs:boolean {
function($d2 as xs:decimal) as xs:boolean { $d2 lt 0 } ($d1)
}
</code></pre>
<p>which should fail with a type error when called supplying an <code>xs:decimal</code>.</p>
<p>However, because the value supplied to the <code>$callback</code> parameter is an instance of the required type, Saxon skips the process of function coercion wrongly believing it to be unnecessary; his has the effect that the type error is not detected.</p> SaxonC - Bug #6333 (In Progress): Representing empty sequencehttps://saxonica.plan.io/issues/63332024-01-29T17:52:37ZO'Neil Delprattoneil@saxonica.com
<p>SaxonC currently does not properly represent empty sequences via the API. What we need is an <code>XdmEmptySequence</code> class similar to its Java counterpart. Moreover, In SaxonJ (Java) an empty <code>XdmValue</code> is also an empty sequence which can be passed as a parameter to an expression of stylesheet, but this fails in SaxonC.</p>
<p>For example:</p>
<pre><code class="python syntaxhl" data-language="python"> <span class="n">xp</span> <span class="o">=</span> <span class="n">saxonproc</span><span class="p">.</span><span class="n">new_xpath_processor</span><span class="p">()</span>
<span class="n">xp</span><span class="p">.</span><span class="n">declare_namespace</span><span class="p">(</span><span class="s">"fn"</span><span class="p">,</span> <span class="s">"http://www.w3.org/2005/xpath-functions"</span><span class="p">)</span>
<span class="n">xp</span><span class="p">.</span><span class="n">declare_variable</span><span class="p">(</span><span class="s">'p'</span><span class="p">)</span>
<span class="n">xdm_value</span> <span class="o">=</span> <span class="n">PyXdmValue</span><span class="p">()</span>
<span class="n">xp</span><span class="p">.</span><span class="n">set_parameter</span><span class="p">(</span><span class="s">'p'</span><span class="p">,</span> <span class="n">xdm_value</span><span class="p">)</span>
<span class="k">assert</span> <span class="n">xp</span><span class="p">.</span><span class="n">effective_boolean_value</span><span class="p">(</span><span class="s">"fn:empty($p)"</span><span class="p">)</span>
</code></pre>
<p>Crashes out with the following exception:</p>
<pre><code>java.lang.IllegalArgumentException: Invalid handle
at com.oracle.svm.core.handles.ObjectHandlesImpl.doGet(ObjectHandlesImpl.java:232)
at com.oracle.svm.core.handles.ObjectHandlesImpl.get(ObjectHandlesImpl.java:220)
at net.sf.saxon.option.cpp.ProcessorDataAccumulator.addProcessorDataPair(ProcessorDataAccumulator.java:93)
</code></pre>
<p>This is probably because the empty <code>PyXdmValue()</code> object is not internally getting converted to an empty sequence.</p> Saxon - Bug #6323 (AwaitingInfo): Nullpointer Exceptionhttps://saxonica.plan.io/issues/63232024-01-18T15:48:06ZUrvish Amin
<p>We are getting NullPointerException , see below. It doesnt give much information about which attribute or specific item it fails. Let us know what could be an issue or how to debug this issue. Can we get source code so we can debug code and see for which element it fails? I have attached our xslt files.</p>

... 94 more</p> Saxon - Support #6322 (New): Is the old collation URI in EE supposed to rely on the JDK collation...https://saxonica.plan.io/issues/63222024-01-17T16:12:22ZMartin Honnenmartin.honnen@gmx.de
<p>I notice differences in collation dependent sorts whether I use the UCA URI or the legacy Saxon URI.</p>
<p>The documentation at <a href="https://www.saxonica.com/html/documentation12/localization/sorting-and-collations.html" class="external">https://www.saxonica.com/html/documentation12/localization/sorting-and-collations.html</a> says about collations</p>
<blockquote>
<p>For backwards compatibility reasons the standard collation resolver in Saxon also accepts URIs in the form <a href="http://saxon.sf.net/collation" class="external">http://saxon.sf.net/collation</a> followed by query parameters; the query parameters that are recognized are the same as those defined by W3C UCA collation URIs.</p>
</blockquote>
<p>It appears to me, however, that with EE, the use of the legacy collation URI means ICU is not used, only the default JDK collation support, as I get results similar to using HE.</p>
<p>Can anyone confirm that?</p>
<p>Details below:</p>
<p>An XQuery program using the UCA collation URI, run with Saxon 12.4 EE, gives the same result for all sorts, e.g. the following program outputs true:</p>
<pre><code>declare namespace array = "http://www.w3.org/2005/xpath-functions/array";
declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization";
declare option output:method 'text';
declare option output:item-separator '&#10;';
declare variable $strings as array(xs:string*) external := [
('abc', 'abc def', 'abcdef'),
('abc', 'abcdef', 'abc def'),
('abc def', 'abcdef', 'abc'),
('abc def', 'abc', 'abcdef'),
('abcdef', 'abc', 'abc def'),
('abcdef', 'abc def', 'abc')
];
let $sorted :=
array:for-each(
$strings,
function($seq) {
sort($seq, 'http://www.w3.org/2013/collation/UCA?strength=primary;lang=en')
})
return
every $pos in (1 to array:size($sorted))
satisfies
deep-equal($sorted($pos), $strings?1)
</code></pre>
<p>The same program using the legacy Saxon collation URI, however, gives different sort result, much like Saxon HE, e.g. the program outputs false:</p>
<pre><code>declare namespace array = "http://www.w3.org/2005/xpath-functions/array";
declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization";
declare option output:method 'text';
declare option output:item-separator '&#10;';
declare variable $strings as array(xs:string*) external := [
('abc', 'abc def', 'abcdef'),
('abc', 'abcdef', 'abc def'),
('abc def', 'abcdef', 'abc'),
('abc def', 'abc', 'abcdef'),
('abcdef', 'abc', 'abc def'),
('abcdef', 'abc def', 'abc')
];
let $sorted :=
array:for-each(
$strings,
function($seq) {
sort($seq, 'http://saxon.sf.net/collation?strength=primary;lang=en')
})
return
every $pos in (1 to array:size($sorted))
satisfies
deep-equal($sorted($pos), $strings?1)
</code></pre>
