XQilla: an XQuery and XPath 2.0 library and command line interpreter.
|
|
|
|
|
|
version 2.2.3 (2009.11.12):
|
|
* Work around for a Xerces-C bug in DOMDocument::importNode() that
|
|
resulted in badly copied prefixes using XQuery Update.
|
|
* Fixed a segfault in the DOM 3 API by orphaning Xerces-C Grammar
|
|
correctly.
|
|
* Fixed optimization of count(), exists(), and empty() based on static
|
|
type if the argument uses doc() or collection().
|
|
* Fixed a bug that caused a crash when using "order by" in some
|
|
circumstances.
|
|
* Fixed query/module static-typing to also (re-)static type the modules
|
|
it imports.
|
|
* Fixed a bug in fn:codepoint-equal().
|
|
|
|
version 2.2.2 (2009.07.02):
|
|
* Fixed XQillaDocumentImpl::cloneNode() to return an instance of
|
|
XQillaDocumentImpl.
|
|
* Fixed XPath 2.0 so that it doesn't recognize entities in
|
|
string literals.
|
|
* Fixed a bug in the constant folding identity transforms for
|
|
arithmetic expressions.
|
|
* Fixed a bug in the undefined context item check.
|
|
* Fixed the transform expression to copy document nodes rather than
|
|
dissolving them.
|
|
* Fixed a bug in the static typing of external functions.
|
|
* Fixed a bug in fn:matches()with a zero-length string as the first
|
|
argument.
|
|
* Fixed a couple of bugs in the debug API, and made it report exit() and
|
|
end() events correctly.
|
|
* Fixed variable inlining so that variables aren't inlined into loops.
|
|
* Fixed a segfault when parsing a document from a memory buffer.
|
|
* Fixed a bug in XQC_Implementation->parse_document_file() that
|
|
caused parsing to always fail.
|
|
* Workaround a bug in Xerces-C that can cause corrupted memory when
|
|
deleting a mutex.
|
|
* Fixed a bug related to unsigned int/XMLSize_t type difference between
|
|
Xerces-C 2.8 and 3.0.
|
|
* Fixed alignment on sparc architectures that could cause a SIGBUS
|
|
crash.
|
|
* Fixed a Windows memory bug involving the URI used in resolving a
|
|
document or collection.

|
|
* Updated libtool version to 2.2.6.
|
|
* Fixed some compiler issues related to the xlC compiler.
|
|
|
|
version 2.2.0 (2009.01.05):
|
|
* Added a debugging API, and a command line debugger invoked by passing
|
|
a "-d" flag to the command line tool.
|
|
* Added a partial implementation of XSLT 2.0. This should currently be
|
|
considered alpha quality.
|
|
* Added an implementation of the current draft of XQC, a standard C API
|
|
for accessing XQuery implementations.
|
|
* Added a prototype implementation of higher order functions for XQuery.
|
|
* Added the ExternalFunctionResolver API to resolve implementations for
|
|
external functions that are unknown before compile time.
|
|
* Added the xqilla:analyze-string() extension function for performing
|
|
complex regular expression analysis.
|
|
* Added query options for controlling schema validation, document
|
|
projection and lint warnings.
|
|
* Added a --disable-rpath configure option for maintainers.
|
|
* Implemented function and variable inlining, and other partial
|
|
evaluation optimizations.
|
|
* Implemented tail recursion optimization.
|
|
* Modified XQilla to compile against Xerces-C 3.0. A source installation
|
|
of Xerces-C is no longer necessary for compilation.
|
|
* Improved static typing with cardinality information.
|
|
* Fixed a bug in schema validation of a document in no namespace.
|
|
* Fixed schema validation to check ID/IDREF constraints correctly.
|
|
* Fixed a bug in validation of SequenceTypes like
|
|
document-node(schema-element(XX)).

|
|
they have a space in their document URIs.
|
|
|
|
version 2.1.4 (2008.07.31):
|
|
* Fixed a bug in XQTreatAs that removed type checking under
|
|
circumstances where it was still needed.
|
|
|
|
version 2.1.3 (2008.07.29):
|
|
* Modified the StaticAnalysis class in order to reduce the memory
|
|
footprint of a prepared query by at least 50%.
|
|
* Changed the code so that compilation against a patched version of
|
|
Xerces-C 2.8 is no longer required. XQilla will build with reduced
|
|
functionality without the patches.
|
|
* Workaround a Windows optimizer issue that caused instance of
|
|
queries to fail in a release build on Windows.
|
|
* Fixed another Solaris compilation bug.
|
|
|

|
|
* Fixed the Xerces-C data model layer to work correctly with DOM Level 1
|
|
elements and attributes.
|
|

|
|
the DOM 3 API with certain schemas.

|
|
|
|

|
|
* Added the xqilla:parse-json() and xqilla:serialize-json() extension
|
|
functions to parse and serialize JSON.
|
|
* Added the xqilla:parse-html() function which uses HTML Tidy to parse
|
|
HTML into XML. The function will not be compiled if TidyLib is not
|
|
found.
|
|
* Added fn:unparsed-text(), a function from XSLT 2.0 which can fetch a
|
|
URL and return it as a string.
|
|
* Added an xqilla:time() function which outputs the time taken to
|
|
evaluate it's argument.
|
|
* Added src/xercesc_content_type.patch which should be applied
|
|
against Xerces-C 2.8 to fix an HTTP connection bug.
|
|
* Added src/xercesc_regex.patch which should be applied against Xerces-C
|
|
2.8 to fix a regular expression bug in fn:replace().
|
|
* Added project files for Visual C++ 8, including 64 bit build
|
|
targets.
|
|
* Changed the default XQuery Update revalidation mode to LAX.
|
|
* Fixed a bug in the lexing of element and attribute content in
|
|
queries that incorrectly rejected certain Unicode characters.

|
|
* Fixed a segfault in XPath2ResultImpl if the results were only
|
|
partially navigated.

|
|
turned into XQillaExceptions.
|
|
* Fixed XQilla to compile using Visual C++ 6.
|
|
* Fixed compilation flags to work under HPUX.
|
|
|
|
version 2.0.0 (2007.12.12):
|
|
* Changed the license for XQilla to the Apache License v2, a more
|
|
permissive open-source licence.
|
|
* Implemented document projection, an optimisation technique that prunes
|
|
sub-trees of documents not needed for the query at parse time. This is
|
|
enabled by default.
|
|
* Added a new extension function xqilla:parse-xml() which takes a string
|
|
and parses it as an XML document.
|
|
* Added optional support for using the FAXPP XML parser instead of the
|
|
Xerces-C parser.
|
|
* Added a command line option to the "xqilla" utility for binding
|
|
external variables from the command line.
|
|
* Implemented better error messages for type errors.
|
|
* Modified the embedded MAPM library so we are now using it under the
|
|
terms of the MIT licence.
|
|
* Fixed miscellaneous bugs in the XQuery Update implementation.
|
|
* Fixed a bug with the algorithm to add and subtract an
|
|
xs:dayTimeDuration to or from an xs:date.
|
|
* Fixed a bug in XercesNodeImpl which caused a segfault if the node was
|
|
created as a value of a global variable in another module.
|
|
|
|
version 1.1.0 (2007.08.31):
|
|
* Added support for XQuery Update (Last Call Working Draft, 28 August
|
|
2007).
|
|
* Added XQillaConfiguration, which encapsulates everything needed to
|
|
create or use a new data model.
|
|
* Implemented a new data model called FastXDM. It places nodes in a
|
|
sequential array, and is much faster and more memory efficient than
|
|
the DOM based data model. This is now the default data model.
|
|
* Implemented XercesConfiguration, to enable use of the Xerces-C DOM
|
|
based data model.
|
|
* Implemented EventHandler, an event based execution interface. This is
|
|
used primarily for efficient evaluation of constructed nodes. This can
|
|
be invoked using XQQuery::execute(EventHandler*,DynamicContext*).
|
|
* Added the ExternalFunction class, to allow users to easily implement
|
|
XQuery external functions.
|
|
* Added the MessageListener interface, to allow users to easily receive
|
|
warning and trace messages.
|
|
* Implemented closures, to enable the efficient and lazy execution of
|
|
"let" expressions.
|
|
* Implemented more lazy execution code for "order by" expressions
|
|
* Added better error messages for sequence type checking errors.
|
|
* Removed the XQDebugCallback API.
|
|
* Rewrote the lexer and parser to be more memory efficient.
|
|
* Rewrote "validate" expressions to be more memory efficient.
|
|
* Modified the XQuery Test Suite runner to run the forthcoming XQuery
|
|
Update test suite.
|
|
* Made minor changes to allow compilation against the Xerces-C 2.8
|
|
release candidate.
|
|
* Fixed a bug in the limit checking of the seconds field in the time
|
|
when parsing.
|
|
* Fixed modules so that the correct language is used to parse the
|
|
module.
|
|
* Fixed a bug in the code to create a new dynamic context for a
|
|
module.
|
|
* Fixed possible segmentation faults and memory leaks when using the
|
|
DOM3 API
|
|
* A number of other miscellaneous minor bug fixes.
|
|
|
|
version 1.0.1 (2007.02.12):
|
|
* Fixed fn:concat() to accept more than 51 arguments.
|
|
* Fixed module parsing, to use the correct language enumeration when
|
|
parsing. Output modules in the query plan.
|
|
* Fixed a race condition in the parsing of function signatures.
|
|
* Fixed parse errors in the DOM3 API, which were being thrown as
|
|
XQException instead of XQillaException. [1626534]
|
|
* Fixed the building of shared libraries under Cygwin, by adding
|
|
-no-undefined to the libtool line in the Makefile. [1639669]
|
|
* Fixed a bug in the static typing of user defined functions, that could
|
|
result in incorrect errors.
