- Single_line_formatting_helper should not accidentally exit the
DISABLED state. No JSON construct should be able to move the
Single_line_formatting_helper from DISABLED state.
The GEOMETRY field metadata is stored in the FRM file.
SRID for a spatial column now can be stored, it was added to the CREATE TABLE syntax,
so the AddGeometryData() stored procedure is now possible. Script adding the required Add/DropGeometryColumn sp-s added.
length/dec/charset are still in LEX, because they're also used
for CAST and dynamic columns.
also
1. fix "MDEV-7041 COLLATION(CAST('a' AS CHAR BINARY)) returns a wrong result"
2. allow BINARY modifier in stored function RETURN clause
3. allow "COLLATION without CHARSET" in SP/SF (parameters, RETURN, DECLARE)
4. print correct variable name in error messages for stored routine parameters
fail CREATE SERVER foreign data wrapper is "mysql"
and neither HOST nor SOCKET are specified.
Also default PORT to 3306 (again, only for foreign
data wrapper "mysql")
- Switch Explain data structure from "flat" representation of
SJ-Materialization into nested one.
- Update functions that print tabular output to operate on the
nested structure.
- Add function to generate JSON output.
- Basic support for JOIN buffering
- The output is not polished but catches the main point:
tab->select_cond and tab->cache_select->cond are printed separately.
- Hash join support is poor still.
- Also fixed identation in JOIN_TAB::save_explain_data
Writing JSON:
- Fix a bug in Single_line_formatting_helper
- Add Json_writer_nesting_guard - safety class
EXPLAIN JSON support
- Add basic subquery support
- Add tests for UNION/UNION ALL.
Simply disallowing equality propagation into LIKE.
A more delicate fix is be possible, but it would need too many changes,
which is not desirable in 10.0 at this point.
Problem is on test it tried to verify that no files were left
on test database.
Fix: There's no need to list other file types, it can only
list *.par files
- Drop all tables in explain_json.test
- Tabular form should print ref='' when type='fulltext' (another peculiarity
of the traditional EXPLAIN format)
- String_list::append_str should allocate memory for \0, too
- Some temporary code for EXPLAIN JSON and join buffering.
* adjust viossl.c to take account the new code
(SSL_get_error is used now, cannot simply remap it)
* remove unnecessary version check
* update the test to 10.0
followup:
* explicitly disable SSLv2 and SSLv3, keep other protocols enabled
* fix a compiler warning
* rename the test and combinations to avoid confusion
vio/viossl.c:
fix a compiler warning
When the optimizer considers an option to use Loose Scan, it should
still consider UNIQUE keys (Previously, MDEV-4120 disabled loose scan
for all kinds of unique indexes. That was wrong)
However, we should not use Loose Scan when trying to satisfy
"SELECT DISTINCT col1, col2, .. colN"
when using an index defined as UNIQU(col1, col2, ... colN).
in mysql_upgrade: do FLUSH PRIVILEGES at the end, not together with
mysql_fix_privilege_tables
mysql-test/t/mysql_upgrade-6984.opt:
use a dummy second option to force server restart after the test
