775f17667b Merge with 4.1 2005-06-07 00:31:53 +03:00
monty@mysql.com
29fd1f2fd9 Move USE_PRAGMA_IMPLEMENTATION to proper place 
Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable

a7a1d4dc1e Fix for BUG#10244: 
Make get_quick_select_for_ref() accept estimated # records as parameter and 
set QUICK_RANGE_SELECT::records, as this value is used to allocate buffers 
in Multi-Range Read.

838eaec709 Fix and testcase for BUG#4984 
The crash is eliminated but still it is weird/inefficent that ROR-intersection is used when performing updates in empty table.

Sanja needs to check out the calling of close_thread_tables() in sp_head.cc

3f1c4ba745 handler interface cleanups: 
more logical table/index_flags
  return  HA_ERR_WRONG_COMMAND instead of abstract methods where appropriate
  max_keys and other limits renamed to max_supported_keys/etc
  max_keys/etc are now wrappers to max_supported_keys/etc 
  ha_index_init/ha_rnd_init/ha_index_end/ha_rnd_end are now wrappers to real {index,rnd}_{init,end} to enforce strict pairing

a46d7542c9 This is first cset for WL#1394 "Optimize index merge when all involved index ranges include only values with equal keys" 
The main idea is to exploit the fact that key scans for "key=const" return ordered sequences of rowids.
