Move tokuftdump and tokuft_logprint man pages to storage/tokudb.
The man pages are now part of tokudb-engine cmake component. This change
is mostly for RPM & DEB based packaging generated through CMake & CPack.
Debian upstream already handles this change via the custom scripts in debian/

This is the only symlink in the repository. Symlinks can cause
trouble when using file systems or operating systems that do not
support them.
Also remove the unused file DartConfig.cmake that refers to the script.

in 10.1+ one should use
MY_CHECK_AND_SET_COMPILER_FLAG("-Wno-address-of-packed-member")
and it's already done in storage/tokudb/PerconaFT/CMakeLists.txt

don't run tokudb tests under tcmalloc,
this is not a supported combination.

In the function test_if_cheaper_ordering we make a decision if using an index is better than
using filesort for ordering. If we chose to do range access then in test_quick_select we
should make sure that cost for table scan is set to DBL_MAX so that it is not picked.

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.

Bug#25135304: RBR: WRONG FIELD LENGTH IN ERROR MESSAGE
commit 47bd3f7cf3c8518f62b1580ec65af2ba7ac13b95
Description:
============
In row based replication, when replicating from a table with a field with
character set set to UTF8mb3 to the same table with the same field set to
character set UTF8mb4 I get a confusing error message:
For VARCHAR: VARCHAR(1) 'utf8mb3' to VARCHAR(1) 'utf8mb4'
"Column 0 of table 'test.t1' cannot be converted from type 'varchar(3)' to
type 'varchar(1)'"
Similar issue with CHAR type as well.
Issue with respect to BLOB types:
For BLOB: LONGBLOB to TINYBLOB - Error message displays incorrect blob type.
"Column 0 of table 'test.t1' cannot be converted from type 'tinyblob' to type
'tinyblob'"
For BINARY to BINARY - Error message displays incorrect type for master side
field.
"Column 0 of table 'test.t' cannot be converted from type 'char(1)' to type
'binary(10)'"
Similar issue exists for VARBINARY type. It is displayed as 'VARCHAR'.
Analysis:
=========
In Row based replication charset information is not sent as part of metadata
from master to slave.
For VARCHAR field its character length is converted into equivalent
octets/bytes and stored internally. At the time of displaying the data to user
it is converted back to original character length.
For example:
VARCHAR(2)- utf8mb3 is stored as:2*3 = VARCHAR(6)
At the time of displaying it to user
VARCHAR(6)- charset utf8mb3:6/3= VARCHAR(2).
At present the internally converted octect length is sent from master to slave
with out providing the charset information. On slave side if the type
conversion fails 'show_sql_type' function is used to get the type specific
information from metadata. Since there is no charset information is available
the filed type is displayed as VARCHAR(6).
This results in confused error message.
For CHAR fields
CHAR(1)- utf8mb3 - CHAR(3)
CHAR(1)- utf8mb4 - CHAR(4)
'show_sql_type' function which retrieves type information from metadata uses
(bytes/local charset length) to get actual character length. If slave's chaset
is 'utf8mb4' then
CHAR(3/4)-->CHAR(0)
CHAR(4/4)-->CHAR(1).
This results in confused error message.
Analysis for BLOB type issue:
BLOB's length is represented in two forms.
1. Actual length
i.e
(length < 256) type= MYSQL_TYPE_TINY_BLOB;
(length < 65536) type= MYSQL_TYPE_BLOB; ...
2. packlength - The number of bytes used to represent the length of the blob
1- tinyblob
2- blob ...
In row based replication only the packlength is written in the binary log. On
the slave side this packlength is interpreted as actual length of the blob.
Hence the length is always < 256 and the type is displayed as tiny blob.
Analysis for BINARY to BINARY type issue:
The character set information is needed to identify a filed's type as char or
binary. Since master side character set information is not available on the
slave side both binary and char fields are displayed as char.
Fix:
===
For CHAR and VARCHAR fields display their length in octets for both source and
target fields. For target field display the charset information if it is
relevant.
For blob type changed the code to use the packlength and display appropriate
blob type in error message.
For binary and varbinary fields use the slave side character set as reference
to map them to binary or varbinary fields.

Reverted incorrect change introduced by 548d03d7.
As result is char**, third qsort() parameter must be sizeof(char*).
Not sizeof(result[0] + 2), which is same as sizeof(result[0]).
Not even sizeof(result[0]) + 2, which would cause invalid memory access.
Proper sorting is responsibility of logfilenamecompare() callback.
