concurrent-insert can now be set to 2 for concurrent inserts when there is holes in the data file
myisam_max_extra_sort_file_size is depricated Ensure that myisam_data_pointer_size is honoured when creating new MyISAM files Changed default value of myisam_data_pointer_size from 4 to 6 to get rid of 'table-is-full' errors include/myisam.h: Change type of myisam_block_size and myisam_concurrent_insert to make them changeable in mysqld.cc Removed not used varaible myisam_max_extra_temp_length include/thr_lock.h: Added extra parameter to get_status myisam/mi_create.c: Ensure that myisam_data_pointer_size is honoured myisam/mi_dynrec.c: If 'append_insert_at_end' is set, only write at end of myisam record file myisam/mi_locking.c: Add extra argument to 'mi_get_status' to allow thr_lock to signal that we want to do a concurrent insert If this is used, we will append new insert rows at end of data file. Change mi_check_status() to allow concurrent_inserts even if there are holes in the file when myisam_concurent_insert=2 myisam/mi_static.c: Change behavior of myisam_concurrent_insert so that setting this to 2 allows inserts even if there is a hole in the data file. Default value is 2 for MyISAM direct usage but will be set to 1 (old default) by mysqld.cc myisam/mi_statrec.c: If 'append_insert_at_end' is set, only write at end of myisam record file myisam/mi_write.c: If 'append_insert_at_end' is set, only write at end of myisam record file myisam/myisamdef.h: Support for insert-at-end even if there is holes in data file mysql-test/r/gis-rtree.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/group_min_max.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/index_merge.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/index_merge_ror.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/merge.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/myisam.result: Test of concurrent_insert=2 mysql-test/r/null.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/preload.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/ps_1general.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/range.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/r/variables.result: concurrent_insert is now a integer, not a boolean myisam_extra_sort_file_size is deleted mysql-test/r/view.result: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/t/index_merge.test: Test result changed because default value for myisam_data_pointer_size is changed from 4 -> 6 mysql-test/t/myisam.test: Test of concurrent_insert=2 mysql-test/t/ps_1general.test: Drop test table mysql-test/t/variables.test: concurrent_insert is now a integer, not a boolean myisam_extra_sort_file_size is deleted mysql-test/t/view.test: Drop tables that may be left from previous tests mysys/thr_lock.c: Extra paramter to get_status to signal if concurrent_insert was used sql/mysqld.cc: concurrent-insert can now be set to 2 for concurrent inserts when there is holes in the data file myisam_max_extra_sort_file_size is depricated sql/set_var.cc: concurrent-insert is now an integer, not a bool myisam_max_extra_sort_file_size is deleted

IMPLEMENTATION
|
||||
Don't allow concurrent inserts if we have a hole in the table.
|
||||
Allow concurrent inserts if we don't have a hole in the table or
|
||||
if there is no active write lock and there is active read locks and
|
||||
myisam_concurrent_insert == 2. In this last case the new

row('s) are inserted at end of file instead of filling up the hole.
|

|
||||
The last case is to allow one to inserts into a heavily read-used table
|
||||
even if there is holes.
|
||||
|
||||
NOTES
|
||||
Rtree indexes are disabled in mi_open()
|

If there is a an rtree indexes in the table, concurrent inserts are
