| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xpath parsing function was using a local string buffer that was deallocated when going out of scope. However references to it are preserved in the XPATH parse tree. This was causing read-after-free. Fixed by making the xpath buffer a local variable inside the Item class for the relevant xpath function, thus being preserved for the duration of the query.

SELECT now also updates timestamp columns - Blob can now have default values - Added new system variable "check_constraint_checks", to turn of CHECK constraint checking if needed. - Removed some engine independent tests in suite vcol to only test myisam - Moved some tests from 'include' to 't'. Should some day be done for all tests. - FRM version increased to 11 if one uses virtual fields or constraints - Changed to use a bitmap to check if a field has got a value, instead of setting HAS_EXPLICIT_VALUE bit in field flags - Expressions can now be up to 65K in total - Ensure we are not refering to uninitialized fields when handling virtual fields or defaults - Changed check_vcol_func_processor() to return a bitmap of used types - Had to change some functions that calculated cached value in fix_fields to do this in val() or getdate() instead. - store_now_in_TIME() now takes a THD argument - fill_record() now updates default values - Add a lookahead for NOT NULL, to be able to handle DEFAULT 1+1 NOT NULL - Automatically generate a name for constraints that doesn't have a name - Added support for ALTER TABLE DROP CONSTRAINT - Ensure that partition functions register virtual fields used. This fixes some bugs when using virtual fields in a partitioning function
* | | MDEV-8010 - Avoid sql_alloc() in Items (Patch #1)Sergey Vojtovich2015-08-211-6/+7
| | | | | | | | | | | | | | | | | | | | | Added mandatory thd parameter to Item (and all derivative classes) constructor. Added thd parameter to all routines that may create items. Also removed "current_thd" from Item::Item. This reduced number of pthread_getspecific() calls from 290 to 177 per OLTP RO transaction.

* | A joint patch for:Alexander Barkov2014-03-231-2/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - MDEV-5689 ExtractValue(xml, 'substring(/x,/y)') crashes - MDEV-5709 ExtractValue() with XPath variable references returns wrong result. Description: 1. The main problem was that that nodeset_func->fix_fields() was called in Item_func_xml_extractvalue::val_str() and Item_func_xml_update::val_str(), which led in some cases to execution of the XPath engine *before* having a parsed XML value. Moved to Item_xml_str_func::fix_fields(). 2. Cleanup: added a new method Item_xml_str_func::fix_fields() and moved most of the code from Item_xml_str_func::fix_length_and_dec() to Item_xml_str_func::fix_fields(), to follow the usual Item layout. 3. Cleanup: a parsed XML value is useless without the raw XML value it was built from. Previously the parsed and the raw values where stored in separate String instances. It was hard to follow how they are synchronized. Added a helper class XML which contains both parsed and raw values. Makes things easier to read and modify. 4. MDEV-5709: const_item() could incorrectly return a "true" result when XPath expression contains users/SP variable references. Now nodeset_func->const_item() is also taken into account to catch such cases. 5. Minor code enhancements.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from a MERGE view. The problem was in the lost ability to be null for the table of a left join if it is a view/derived table. It hapenned because setup_table_map(), was called earlier then we merged the view or derived. Fixed by propagating new maybe_null flag during Item::update_used_tables(). Change in join_outer.test and join_outer_jcl6.test appeared because IS NULL reported no used tables (i.e. constant) for argument which could not be NULL and new maybe_null flag was propagated for IS NULL argument (Item_field) because table the Item_field belonged to changed its maybe_null status.
