bar@mysql.com/bar.intranet.mysql.r18.ru	bc0c69ce7e	Bug#20795: extractvalue() won't accept names containing a dot (.) Dot character was not considered as a valid identifier body character.	20 years ago
bar@mysql.com	013fb25ff4	Additional fix for 18201 XML: ExtractValue works even if the xml fragment is not well-formed xml Changing error number	20 years ago
bar@mysql.com	8fb685c254	Bug#18201: XML: ExtractValue works even if the xml fragment is not well-formed xml Problem: - ExtractValue silently returned NULL if a wrong XML value is passed. - In some cases "unexpected END-OF-INPUT" error was not detected, and a non-NULL result could be returned for a bad XML value. Fix: - Adding warning messages, to make user aware why NULL was returned. - Missing "unexpected END-OF-INPUT" error is reported now.	20 years ago
bar@mysql.com	faee72a936	Bug#18170: XML: ExtractValue(): XPath expression can't use QNames (colon in names) Problem source: Qualified names (aka QName) didn't work as tag names and attribute names, because the parser lacked a real rule to scan QName, so it understood only non-qualified names without prefixes. Solution: New rule was added to check both "ident" and "ident:ident" sequences.	20 years ago
bar@mysql.com	df2d425afd	Bug#16233: XML: ExtractValue() fails with special characters ExtractValue didn't understand tag and attribute names consisting of "tricky" national letters (e.g. latin accenter letters). It happened because XPath lex parser recognized only basic latin letter a..z ad a part of an identifier. Fixed to recognize all letters by means of new "full ctype" which was added recently.	20 years ago
bar@mysql.com	334af05334	Bug#16319: XML: extractvalue() returns syntax errors for some functions	20 years ago
bar@mysql.com	9bf1fb4c19	Bug#18285: ExtractValue not returning character data within <![CDATA[]]> as expected	20 years ago
bar@mysql.com	2e7cf881ac	Bug #18172 XML: Extractvalue() accepts mallformed XPath without a XPath syntax error item_xmlfunc.cc: Error message didn't happen because after a failing attempt to parse RelativeLocationPath, my_xpath_parse_AbsoluteLocationPath() returned success. Changeing logic a bit: - Try to parse EOF first, return success if true. - Then try to parse RelativeLocationPath(), return success if true. - Otherwise return failure. xml.result: Adding test case. Also, this change made it possible to generate an error message earlier in the case of another bad XPATH syntax. xml.test: Adding test case.	20 years ago
bar@mysql.com	e983bc7486	xml.result, xml.test: Adding test. item_xmlfunc.cc: Bug #18171 XML: ExtractValue: the XPath position() function crashes the server! Disallowing use of position() and last() without context.	20 years ago
bar@mysql.com	f516d1f9f2	Bug#16318: XML: extractvalue() incorrectly returns last() = 1 xml.result, xml.test: Adding test case. item_xmlfunc.cc: - adding "size" member into MY_XPATH_FLT struct, to pass parent's context size when iterating in a predicate. Previously, temporaty context size was calculated instead, which is always 1. As a result, things like last() and count() didn't work fine. - adding iteration into Item_func_xpath_elementbyindex: similar to Item_func_xpath_predicate. This is to make things like last() and count() work inside square brackets.	20 years ago
bar@mysql.com	5e2ab5f4a0	Bug#16316: XML: extractvalue() is case-sensitive with contains() xml.result, xml.test: Adding test case. item_xmlfunc.cc: Fixed that Item_nodeset_func derived classes didn't take into account charset of the XML value and always worked using "binary" charset.	20 years ago
bar@mysql.com	47b4f00720	Bug#16315 XML: extractvalue() handles self badly xml.result, xml.test: Adding test case. item_xmlfunc.cc: Adding a special function to handle "self" axis. Previously "child" and "self" were handled the same.	20 years ago
gluh@eagle.intranet.mysql.r18.ru	701110c943	Bug#16320 XML: extractvalue() won't accept names containing underscores added '_' to allowed tag body symbols	20 years ago
bar@mysql.com	bcc72ad04f	Bug#16313 XML: extractvalue() ignores '!' in names xml.result, xml.test: Adding test case. item_xmlfunc.cc: Fixed that the "!" character written at the end was ignored. Now if we try to scan "!=", and if "!" is not followed by "=", we rollback lex scanner back to "!" token, so the parser will start to check the next rule from the "!" character again. Previously parser started from the next character, which was EOF in the example in xml.test, which led to query being successfully parsed, instead of producing a syntax error.	20 years ago
bar@mysql.com	1f30b1525a	xml.test: xml.result: Adding test for Bug #16312 XML: extractvalue() crash if angle brackets, A fix for #16234 fixed this bug automatically.	20 years ago
bar@mysql.com	f057c9b4e7	Bug#16234 XML: Crash if ExtractValue() Also fixes 16314: XML: extractvalue() crash if vertical bar xml.result, xml.test: Adding test case item_xmlfunc.cc: Using root element as a context node, instead of NULL, with relative paths.	20 years ago
bar@mysql.com	519f9d628c	Adding XPath support: ExtractValue and UpdateXML functions. libmysqld/Makefile.am: sql/Makefile.am: Adding new source files. Adding new file into build process. include/my_xml.h: strings/xml.c: Adding new XML parse flags to skip text normalization and to use relative tag names. Adding enum for XML token types. sql/lex.h: Making parser aware of new SQL functions. sqll/item_create.h, sql/item_create.cc: Adding creators for ExtractValue and UpdateXML. sql/item.h: Adding new Item types: nodeset and nodeset comparator. sql/item_xmlfunc.h sql/item_xmlfunc.cc Adding new classes implementing XPath functions. mysql-test/t/xml.test, mysql-test/r/xml.result: New files: adding test case	20 years ago
