Don't enable HA_EXTRA_WRITE_CACHE if too few rows
Revert main parts of patch for online index builds. Should be done differently Added support for %lx in my_snprintf() sql/ha_myisam.cc: Don't enable HA_EXTRA_WRITE_CACHE if too few rows sql/handler.h: Indentaion fix sql/mysql_priv.h: Removed real_alter_table, mysql_add_column and mysql_drop_column sql/sql_class.cc: After merge fix sql/sql_insert.cc: Don't user bulk_insert if only one row (common case) sql/sql_parse.cc: Added mysql_create_index() and mysql_drop_index() as these are only wrappers for mysql_alter_table() sql/sql_table.cc: Revert main parts of patch for online index builds Changed back to use tabs to make merges possible between trees sql/unireg.cc: Added comments and minor cleanup strings/my_vsnprintf.c: Added support for %lx. Proper long support

CREATE INDEX and DROP INDEX are implemented by calling ALTER TABLE with

cases.

In the future ALTER TABLE will notice that only added indexes

and create these one by one for the existing table without having to do

a full rebuild.

One should normally create all indexes with CREATE TABLE or ALTER TABLE.
