*	MDEV-7860: EXPLAIN FORMAT=JSON crashes for loose scan query	Sergei Petrunia	2015-04-08	1	-0/+71
\| \| \| \| \| \| \|	(Based on original patch by Sanja Byelkin) Make the code that produces JSON output handle LooseScan quick select. The output we produce is compatible with MySQL 5.6.
*	MDEV-7927: Server crashes in in Time_and_counter_tracker::incr_loops	Sergei Petrunia	2015-04-08	1	-0/+8
\| \| \| \| \|	- JOIN::save_explain_data should also set JOIN::tracker (it already sets join_tab[0].tracker). This is needed for UNIONs inside subqueries.
*	Add a testcase for EXPLAIN FORMAT=JSON for ROR-union index_merge.	Sergei Petrunia	2015-02-17	1	-0/+3
\|
*	Merge bb-10.1-explain-json into 10.1	Sergei Petrunia	2014-12-06	1	-1/+19
\|\
\| *	EXPLAIN JSON: Print out the "expensive constant condition" attached to joins.	Sergei Petrunia	2014-12-06	1	-1/+19
\| \|
* \|	MDEV-7264: Assertion `0' failed in subselect_engine::get_identifier()	Sergei Petrunia	2014-12-06	1	-0/+12
\|/ \| \| \| \| \| \| \|	Switch EXPLAIN JSON from using subselect_engine::get_identifier() to the number from Item_subselect::unit. Remove subselect_union_engine::get_identifier() because it was added only for EXPLAIN JSON code.
*	EXPLAIN FORMAT=JSON: Full scan on NULL key (join case)	Sergei Petrunia	2014-12-06	1	-0/+14
\|
*	EXPLAIN FORMAT=JSON: Support "range checked for each record"	Sergei Petrunia	2014-12-06	1	-0/+5
\|
*	EXPLAIN FORMAT=JSON: Support range+MRR plans (when MRR is used but BKA is not)	Sergei Petrunia	2014-12-06	1	-0/+12
\|
*	EXPLAIN FORMAT=JSON	Sergei Petrunia	2014-12-02	1	-0/+19
\| \| \| \| \|	Add support for semi-join strategies: FirstMatch, DuplicateWeedout, LooseScan.
*	EXPLAIN FORMAT=JSON: support SJ-Materialization	Sergei Petrunia	2014-12-01	1	-1/+10
\| \| \| \| \| \| \| \|	- 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.
*	EXPLAIN FORMAT=JSON: support EXPLAIN FORMAT=JSON INSERT ...	Sergei Petrunia	2014-11-29	1	-1/+8
\|
*	EXPLAIN FORMAT=JSON: Add support for non-merged semi-joins	Sergei Petrunia	2014-11-29	1	-0/+6
\|
*	EXPLAIN FORMAT=JSON: support derived tables	Sergei Petrunia	2014-11-28	1	-0/+13
\|
*	Make explain_json.test pass on case-insensitive FS.	Sergei Petrunia	2014-11-28	1	-2/+2
\|
*	EXPLAIN FORMAT=JSON: Add support for single-table UPDATE/DELETE.	Sergei Petrunia	2014-11-28	1	-0/+10
\|
*	EXPLAIN FORMAT=JSON: support join buffering	Sergei Petrunia	2014-11-27	1	-0/+12
\| \| \| \| \| \| \| \| \|	- 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
*	EXPLAIN FORMAT=JSON: further development	Sergei Petrunia	2014-11-27	1	-0/+20
\| \| \| \| \| \| \| \| \| \|	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.
*	Make testsuite to pass	Sergei Petrunia	2014-11-21	1	-1/+1
\| \| \| \| \| \| \| \|	- 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.
*	EXPLAIN FORMAT=JSON: produce used_key_parts, JSON-ish output for index_merge.	Sergei Petrunia	2014-08-14	1	-3/+18
\|
*	MDEV-6109: EXPLAIN JSON	Sergei Petrunia	2014-08-12	1	-9/+9
\| \| \| \|	Add pretty-printing of possible_keys column.
*	MDEV-6109: EXPLAIN JSON	Sergei Petrunia	2014-08-09	1	-0/+27
	- Add first testcases - Don't overquote when printing conditions - Other small output fixes
