Release Notes

January 14, 2008: Qizx/db is now a XMLmind product

Please visit http://www.xmlmind.com/qizx/.

Version 0.2p7 -Sept 23, 2007

• Bug fix:
  • Serialization: The <?xml declaration was appearing in HTML, even with the option omit-xml-declaration equal to true.

Version 0.2p6 -June 11, 2007

• Bug fix:
  • Serialization: characters not supported by the encoding are now output as a character entity reference. in HTML mode, symbolic character entities defined in HTML4 are used if the encoding cannot represent them: for example Unicode character U+8482 (TM sign) is output as &trade;
  • Java API: the QName passed as argument of the "endElement" event in SAXEventHandler and derived classes (eg NodeXMLReader) was not correct.

Version 0.2p5 -Feb 17, 2007

• Bug fixing:

  • Java binding issue with overloaded methods: the basic problem is that XQuery does not support function overloading, therefore calling overloaded Java methods bound as XQuery functions should not be supported by Qizx in principle. This feature was however partially supported in Qizx/open 1.0 but the changes in type handling in 1.1 have made it nearly unusable.

    Qizx/db 0.2p5 attempts to improve on the current situation: the types of arguments (declared or inferred) are used to select the best matching overloaded method. This should solve most cases. However there are still issues when argument types map to xdt:object.

    See the documentation for more details and for examples.

Version 0.2p4 -Nov 13, 2006

• Bug fixing:
  • The "export results" command now saves all items of the sequence (not only the displayed items)
  • indexing: in a collection containing more than 4096 documents, the first documents were invisible.
  • Some query result sequences were not rewinding properly (for example //X[@attr > 1])
• The Java API documentation (javadoc) has been withdrawn from the web site. Available in the distribution package.

Version 0.2p3 -Oct 1st, 2006

Bug fixing and conformance release: passes 99.9% of all 'MinimalConformance' tests from the latest instalment (v1.0) of the XQuery Test Suite. Passes also all the tests of the optional feature "Modules".

Remaining issues:

• Functions id/idref. Implemented for parsed documents, but not yet for database documents.
• Advanced Unicode features: surrogates and normalizations. Low priority, as very few users are likely to be concerned.

Other bug fixes:

• Compilation bug in complex FLWOR expressions [B. Haible/ILOG]

Version 0.2p2 - Sep 3, 2006

Bug fixing and conformance release: passes more than 99.5% of all 'MinimalConformance' tests from the latest instalment (v1.0) of the XQuery Test Suite. Passes also all the tests of the optional feature "Modules".

Remaining issues (0.5%) mainly concern:

• Functions id/idref. Will be implemented, but not in the near future.
• Advanced Unicode features: surrogates and normalizations. Low priority, as very few users are likely to be concerned.

New features:

• The collection() function now accepts a list of document URI's separated by commas or semicolons.

Version 0.2p1 - June 29, 2006

Bug fixing version:

• Slight improvements in conformance: 96.5% of XQuery Test Suite 0.9 (95% of XQTS 0.9.4)
• Fixed blocking bug in namespace handling (wrong "duplicate attribute" error).
• Introduced 3 new function names in SQL Connectivity, due to an issue with function overloading: sqlx:execStatement, sqlx:rawExecStatement, sqlx:execUpdateStatement.

Known bugs, not yet fixed:

• Java binding: trying to call overloaded methods or constructors in a Java class may fail in a platform dependent way. The issue was already existing in 0.1 but has been worsened by type-checking changes in 0.2.

Version 0.2 (alpha) - May 29, 2006

• GUI improvements in XQuest Studio: persistent history, XML-like display, results displayed by blocks, export of results, memory monitoring, monitoring of background server tasks, document cache control.
• Indexing Sheets: the default date sifter now recognizes ISO date and date-time. More options in built-in sifters. Custom sifters can receive parameters.
• Collection Delete has been implemented.
• The QuickStart tutorial has a new chapter about full-text queries.

• XQuest 0.2 passes over 96% of XQTS 0.9, the official test suite (against about 93% in version 0.1). Note that XQTS 0.9 itself is not yet completely correct (up to 2% of broken tests).

• Bug fixes (bugs reported by users):
  • The XQSP demos have been fixed and enriched.
  • the cache of DocumentManager now detects a modification of the source file of a document.
  • a bug in an IO method could occasionally make the index compacter loop forever.

Initial alpha release Version 0.1 - April 10, 2006

This version is already fairly fast and scalable, but may suffer some functional instability, hence the term "alpha".
