MDEV-19486 and one more similar bug appeared because handler::write_row() interface
welcomes to modify buffer by storage engine. But callers are not ready for that
thus bugs are possible in future.
handler::write_row():
handler::ha_write_row(): make argument const
A read-only storage engine that stores it's data in (aws) S3
To store data in S3 one could use ALTER TABLE:
ALTER TABLE table_name ENGINE=S3

MDEV-16249 CHECKSUM TABLE for a spider table is not parallel and saves all data in memory in the spider head by default
MDEV-10130 Assertion `share->in_trans == 0' failed in storage/maria/ma_close.c
MDEV-10378 Assertion `trn' failed in virtual int ha_maria::start_stmt
The problem was that maria_handler->trn was not properly reset
at commit/rollback and ha_maria::exernal_lock() could get confused
because.
There was some old code in ha_maria::implicit_commit() that tried
to take care of this, but it was not bullet proof.
Fixed by adding list of all tables that is part of the maria transaction to
TRN.
A nice side effect was of the fix is that loops in
ha_maria::implict_commit() got to be much simpler.
Other things:
- Fixed a bug in mysql_admin_table() where argument open_for_modify
was wrongly reset for the next table in the chain
- rollback admin command also in case of fatal error.
- Split _ma_set_trn_for_table() to three version to simplify code
and debugging.
- Several new asserts to detect the original problem (that file was
not properly removed from trn before calling ma_close())
Benefits of this patch:
- Removed a lot of calls to strlen(), especially for field_string
- Strings generated by parser are now const strings, less chance of
accidently changing a string
- Removed a lot of calls with LEX_STRING as parameter (changed to pointer)
- More uniform code
- Item::name_length was not kept up to date. Now fixed
- Several bugs found and fixed (Access to null pointers,
access of freed memory, wrong arguments to printf like functions)
- Removed a lot of casts from (const char*) to (char*)
Changes:
- This caused some ABI changes
- lex_string_set now uses LEX_CSTRING
- Some fucntions are now taking const char* instead of char*
- Create_field::change and after changed to LEX_CSTRING
- handler::connect_string, comment and engine_name() changed to LEX_CSTRING
- Checked printf() related calls to find bugs. Found and fixed several
errors in old code.
- A lot of changes from LEX_STRING to LEX_CSTRING, especially related to
parsing and events.
- Some changes from LEX_STRING and LEX_STRING & to LEX_CSTRING*
- Some changes for char* to const char*
- Added printf argument checking for my_snprintf()
- Introduced null_clex_str, star_clex_string, temp_lex_str to simplify
code
- Added item_empty_name and item_used_name to be able to distingush between
items that was given an empty name and items that was not given a name
This is used in sql_yacc.yy to know when to give an item a name.
- select table_name."*' is not anymore same as table_name.*
- removed not used function Item::rename()
- Added comparision of item->name_length before some calls to
my_strcasecmp() to speed up comparison
- Moved Item_sp_variable::make_field() from item.h to item.cc
- Some minimal code changes to avoid copying to const char *
- Fixed wrong error message in wsrep_mysql_parse()
- Fixed wrong code in find_field_in_natural_join() where real_item() was
set when it shouldn't
- ER_ERROR_ON_RENAME was used with extra arguments.
- Removed some (wrong) ER_OUTOFMEMORY, as alloc_root will already
give the error.
TODO:
- Check possible unsafe casts in plugin/auth_examples/qa_auth_interface.c
- Change code to not modify LEX_CSTRING for database name
(as part of lower_case_table_names)
This was done to make it clear that a update_row() should not change the
row.
This was not done for handler::write_row() as this function still needs
to update auto_increment values in the row. This should at some point
be moved to handler::ha_write_row() after which write_row can also have
const arguments.

Bug#17647863: MYSQL DOES NOT COMPILE ON OSX 10.9 GM

Added support for --crash-script.

Patch by Eric Bergen
storage/maria/ha_maria.h:
Removed not existing variable.
The patch lifts the limitation of the current implementation
of ALTER TABLE that does not allow to build unique/primary
indexes by sort for MyISAM and Aria engines.
- index_merge/intersection is unable to work on GIS indexes, because:
1. index scans have no Rowid-Ordered-Retrieval property
2. When one does an index-only read over a GIS index, they do not
get the index tuple, because index only contains bounding box of the geometry.
This is why key_copy() call crashed.
This patch fixes#1, which makes the problem go away. Theoretically, it would
be nice to check #2, too, but SE API semantics is not sufficiently precise to do it.
Fixed failing tests in sys_vars as we have now stricter checking of setting of variables.

- "Using MRR" is no longer shown with range access.
- Instead, both range and BKA accesses will show one of the following:
= "Rowid-ordered scan"
= "Key-ordered scan"
= "Key-ordered Rowid-ordered scan"
depending on whether DS-MRR implementation will do scan keys in order, rowids in order,
or both.
- The patch also introduces a way for other storage engines/MRR implementations to
pass information to EXPLAIN output about the properties of employed MRR scans.
