* Add resetStringInfo(), which clears the content of a StringInfo, andNeil Conway2007-03-03
| | | | | | fixup various places in the tree that were clearing a StringInfo by hand. Making this function a part of the API simplifies client code slightly, and avoids needlessly peeking inside the StringInfo interface.
* Fix date/time formats for XML Schema output.Peter Eisentraut2007-03-01
| | | | Pavel Stehule
* Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len).Tom Lane2007-02-27
| | | | | | | | | | | Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with VARSIZE and VARDATA, and as a consequence almost no code was using the longer names. Rename the length fields of struct varlena and various derived structures to catch anyplace that was accessing them directly; and clean up various places so caught. In itself this patch doesn't change any behavior at all, but it is necessary infrastructure if we hope to play any games with the representation of varlena headers. Greg Stark and Tom Lane
* Better fix for determining minimum and maximum int64 values that doesn'tPeter Eisentraut2007-02-16
| | | | require stdint.h and works for "busted" int64.
* Add stdint.h includePeter Eisentraut2007-02-16

* Functions for mapping table data and table schemas to XML (a.k.a. XML export)Peter Eisentraut2007-02-16

* Un-break build on ANSI compilers (like msvc) by moving Assert to positionMagnus Hagander2007-02-13
| | | | after variable declarations.
* Add support for optionally escaping periods when converting SQL identifiersPeter Eisentraut2007-02-11
| | | | to XML names, which will be required for supporting XML export.
* Add proper mapping of boolean type data to XML Schema.Peter Eisentraut2007-02-10

* Implement XMLSERIALIZE for real. Analogously, make the xml to text castPeter Eisentraut2007-02-03
| | | | | | | | | observe the xmloption. Reorganize the representation of the XML option in the parse tree and the API to make it easier to manage and understand. Add regression tests for parsing back XML expressions.
* Reactivate libxml memory management via palloc, now that I think I'vePeter Eisentraut2007-01-27
| | | | | classified the conditions under which this is safe to do (see source code comment).
* Add trailing zero byte in Unicode codepoint conversion.Peter Eisentraut2007-01-27
|
* Various fixes in the logic of XML functions:Peter Eisentraut2007-01-25
| | | | | | | | | | | | | | | | - Add new SQL command SET XML OPTION (also available via regular GUC) to control the DOCUMENT vs. CONTENT option in implicit parsing and serialization operations. - Subtle corrections in the handling of the standalone property in xmlroot(). - Allow xmlroot() to work on content fragments. - Subtle corrections in the handling of the version property in xmlconcat(). - Code refactoring for producing XML declarations.
* Simplify handling of XML error messages: Just use the string provided byPeter Eisentraut2007-01-23
| | | | | | | | | libxml as the detail message. As per <http://archives.postgresql.org/pgsql-hackers/2006-12/msg01087.php>. For converting error codes to messages, we only need to cover those codes that we raise ourselves now.
* Fix xmlconcat by properly merging the XML declarations. Add aggregatePeter Eisentraut2007-01-20
| | | | function xmlagg.
* Add support for converting binary values (i.e. bytea) into xml values,Peter Eisentraut2007-01-19
| | | | | with new GUC parameter "xmlbinary" that controls the output encoding, as per SQL/XML standard.
* Clean up encoding issues in the xml type: In text mode, encodingPeter Eisentraut2007-01-18
| | | | | declarations are ignored and removed, in binary mode they are honored as specified by the XML standard.
* Add support for xmlval IS DOCUMENT expression.Peter Eisentraut2007-01-14
|
* Use XML output escaping also in XMLFOREST.Peter Eisentraut2007-01-12
|
* Allow for arbitrary data types as content in XMLELEMENT. The originalPeter Eisentraut2007-01-12
| | | | | coercion to type xml was a mistake. Escape values so they are valid XML character data.
* Use libxml's xmlwriter API for producing XML elements, instead of doingPeter Eisentraut2007-01-10
| | | | | our own printing dance. This does a better job of quoting and escaping the values.
* Some fine-tuning of xmlpi in corner cases:Peter Eisentraut2007-01-07
| | | | | | - correct error codes - do syntax checks in correct order - strip leading spaces of argument
* Allow XML fragment to contain a XML declaration. For that, we need a smallPeter Eisentraut2007-01-07
| | | | | hand-crafted parser for the XML declaration, because libxml doesn't seem to allow this.
* Replace xmlroot with a properly functioning version that parses the value,Peter Eisentraut2007-01-06
| | | | | | | | | sets the items, and serializes the value back (rather than adding an arbitrary number of XML preambles as before). The libxml memory management via palloc had to be disabled because it crashes when libxml tries to access memory that was helpfully freed earlier by PostgreSQL. This needs further thought.
* Update CVS HEAD for 2007 copyright. Back branches are typically notBruce Momjian2007-01-05
| | | | back-stamped for this.
* Fix multiple breakages in last XML patch.Tom Lane2006-12-29

* De-escape XML names when reverse-compiling XML expressions.Peter Eisentraut2006-12-29
|
* Add send and recv functions for xml type.Peter Eisentraut2006-12-28
|
* Handle content and document options in xmlparse() correctly.Peter Eisentraut2006-12-28
|
* Bring some order and sanity to error handling in the xml patch.Tom Lane2006-12-24
| | | | | | | | | | | Use a TRY block instead of (inadequate) ad-hoc coding to ensure that libxml is cleaned up after a failure. Report the intended SQLCODE instead of defaulting to XX000. Avoid risking use of a dangling pointer by keeping the persistent error buffer in TopMemoryContext. Be less trusting that error messages don't contain %. This patch doesn't do anything about changing the way the messages are put together --- this is just about mechanism.
* Fix machine-dependent crash in sqlchar_to_unicode(). Get rid ofTom Lane2006-12-24
| | | | | | | bletcherous and unsafe manipulation of global encoding setting. Clean up libxml reporting mechanism a bit (it still looks like a dangling-pointer crash waiting to happen, though, not to mention being far less than sane from a localization standpoint).
* Code review for XML patch. Instill a bit of sanity in the location ofTom Lane2006-12-24
| | | | | | | the XmlExpr code in various lists, use a representation that has some hope of reverse-listing correctly (though it's still a de-escaping function shy of correctness), generally try to make it look more like Postgres coding conventions.
* Suppress various compiler warnings in new xml code.Tom Lane2006-12-23

* Initial SQL/XML support: xml data type and initial set of functions.Peter Eisentraut2006-12-21
