The reason for this is to make all temporary file names similar and
also to be able to figure out from where a #sql-xxx name orginates.
New format is for most cases:
'#sql-name-current_pid-thread_id[-increment]'
Where name is one of subselect, alter, exchange, temptable or backup
The exceptions are:
ALTER PARTITION shadow files:
'#sql-shadow-thread_id-'original_table_name'
Names used with temp pool:
'#sql-name-current_pid-pool_number'
Apparently, regular expression operations that remove entire lines
of output do not work with list_files, and hence the adjustments in
commit 1c282d4bc4 were ineffective.
For cat_file (preceded by list_files_write_file) the replace_regex
does work.
For some reason, for suite/parts/inc/partition_crash_exchange.inc
some file names will be lost when using list_files_write_file
instead of list_files.
We use a precise pattern match. dict_mem_create_temporary_tablename()
is generating #sql-ib names followed by decimal digits only.
This allows one to run the test suite even if any of the following
options are changed:
- character-set-server
- collation-server
- join-cache-level
- log-basename
- max-allowed-packet
- optimizer-switch
- query-cache-size and query-cache-type
- skip-name-resolve
- table-definition-cache
- table-open-cache
- Some innodb options
etc
Changes:
- Don't print out the value of system variables as one can't depend on
them to being constants.
- Don't set global variables to 'default' as the default may not
be the same as the test was started with if there was an additional
option file. Instead save original value and reset it at end of test.
- Test that depends on the latin1 character set should include
default_charset.inc or set the character set to latin1
- Test that depends on the original optimizer switch, should include
default_optimizer_switch.inc
- Test that depends on the value of a specific system variable should
set it in the test (like optimizer_use_condition_selectivity)
- Split subselect3.test into subselect3.test and subselect3.inc to
make it easier to set and reset system variables.
- Added .opt files for test that required specfic options that could
be changed by external configuration files.
- Fixed result files in rockdsb & tokudb that had not been updated for
a while.
