filename_to_tablename() in MariaDB produces warnings when its is
called for temporary file names.
Don't call this function for temporary filename (as we don't need
its result anyway)
- MariaDB has different wording for a few error messages
- MySQL changed Extra='' to Extra=NULL for EXPLAIN outputs, MariaDB didnt
- The testsuite in storage/rocksdb/mysql-test needs paths to include
files adjusted
- In SHOW COLUMNS output, Extra column is "NULL" in MariaDB vs '' in MySQL
Running MTR tests produces an error like this after the test run:
... 140562896741120 [ERROR] Invalid (old?) table or database name '.rocksdb'
There seems to be no way to have the MariaRocks to prevent these, so
the current way to fix them is to have --ignore-db-dirs in my.cnf
In MariaDB, Field::make_sort_key stores NULL-indicator byte for
the field.
In MySQL, it doesn't, so MyRocks stores the NULL-indicator itself.
Switch to using Field::sort_string, which is the same as
Field::make_sort_key in MySQL.
- Add include/have_rocksdb.inc (TODO: is there any way to have this
file somewhere under storage/rocksdb/mysql-test ?)
- Make rocksdb.test require have_partition.inc because it uses
partitioned tables
- RocksDB uses RTTI (e.g. it uses dynamic_cast)
- mysql-5.6 has RTTI enabled for the whole server, so there's no
conflict.
- MariaDB doesn't have RTTI enabled
So the solution is to enable RTTI for
- RocksDB files
- Parts of MyRocks that interface with RocksDB features that require RTTI.
(If one just enables RTTI for all of MyRocks, they will get a
"undefined reference to `typeinfo for handler'" link error)
The original parameter comes from
commit a869c56d361bb44f46c0efeb11a8f03561676247
write/sync redo log before flushing binlog cache to file
we've already disabled some of that patch in

(why are table reads/writes/updates collected in ha_statistics?
this structure was intended for table statistics that the engine
reports.. and now it is also used for engine-agnostic statistics
like rows_read, rows_requested, etc?)
