- Fixed tests
- Optimized new code
- Fixed some unlikely core dumps
- Better bug fixes for:
- #14397 - OPTIMIZE TABLE with an open HANDLER causes a crash
- #14850 (ERROR 1062 when a quering a view using a Group By on a column that can be null
Now does averaging when running iterations.
Realligned a bunch of code and continued to remove global variables.
Added CSV output along with printable.
Structures are now provided for print options so adding XML, HTML, ... should now be trivial.
- Encoding itself, implemented as a charset
"filename". Originally planned to use '.'
as an escape character, but now changed to '@'
for two reasons: "ls" does not return
file names starting with '.' considering them
as a kind of hidden files; some platforms
do not allow several dots in a file name.
- replacing many calls of my_snprintf() and
strnxmov() to the new build_table_filename().
- Adding MY_APPEND_EXT mysys flag, to append
an extention rather that replace it.
- Replacing all numeric constants in fn_format
flag arguments to their mysys definitions, e.g.
MY_UNPACK_FILENAME,
- Predictability in several function/methods:
when a table name can appear with or withot .frm
extension. Some functions/methods were changed
so accept names strictly with .frm, other - strictly
without .frm extensions. Several DBUG_ASSERTs were
added to check whether an extension is passed.
Many files:
table name to file name encoding
mysql_priv.h:
Prototypes for new table name encoding tools.
ctype-utf8.c:
Implementing "filename" charset for
table name to file name encoding.
row0mysql.c:
Fixing table name prefix.
mf_format.c:
Adding MY_APPEND_EXT processing.
Many files:
Fixing tests.
my_sys.h:
Adding new flag to append rather than replace an extension.
m_ctype.h:
Adding "filename" charset definition.
When InnoDB compares varchar field in ucs2 with given key using bin collation,
it calls my_strnncollsp_ucs2_bin() to perform comparison.
Because field length was lesser than length of key field should be padded
with trailing spaces in order to get correct result.
Because my_strnncollsp_ucs2_bin() was calling my_strnncollp_ucs2_bin(), which
doesn't pads field, wrong comparison result was returned. This results in
wrong result set.
my_strnncollsp_ucs2_bin() now compares fields like my_strnncollsp_ucs2 do,
but using binary collation.
- Added more comments.
- Added a RANGE_OPT_PARAM::remove_jump_scans flag that disables construction of index_merge
SEL_TREEs that represent unusable conditions like "key1part1<c1 OR key2part2<c2"
- make prune_partitions() function handle the case where range analysis produces a list of
index_merge trees (it turned out that this is possible, appropriate test case added).
- Other small fixes.
--engine="myisam,archive"
--number-of-rows has been removed for the time being and replaced with
option to allow you to just repeat multiple time all of the inserts you specifed with data. When number-of-rows-returns it will be instead used for averaging rows while growing concurrency.
Returned stats now has accurent row and query counts since it includes a multiple for the rows and queries added.
Parser is now a touch smarter and understands end of file issues if you have a delimiter at the end of the file.
1) Parsing now works
2) Options are safer, aka it doesn't kill the machine and it cleans up after itself
3) Option of --only-print added so that you can see what it does.
4) Tiny cleanup of the auto generate sql. A lot more needs to be done with this, for it to be very valuable. I suspect it doesn't work all that well.
5) Delimeter is now a single character. No good escaping going on.
6) You can now change which schema it is runninng against.
Now I think I can go make use of it!
Though I need to add support for a "only run this many inserts, divide by the number of clients connecting, to really test scaling"
