* remove unused (and not implemented) WRITE_NET type
* remove cast in my_b_write() macro. my_b_* macros are
function-like, casts are responsibility of the caller
* replace hackish _my_b_write(info,0,0) with the explicit
my_b_flush_io_cache() in my_b_write_byte()
* remove unused my_b_fill_cache()
* replace pbool -> my_bool
* make internal IO_CACHE functions static
* reformat comments, correct typos, remove obsolete comments (ISAM)
* assert valid cache type in init_functions()
* use IO_ROUND_DN() macro where appropriate
* remove unused DBUG_EXECUTE_IF in _my_b_cache_write()
* remove unnecessary __attribute__((unused))
* fix goto error in parse_file.cc
* remove redundant reinit_io_cache() in uniques.cc
* don't do reinit_io_cache() if the cache was not initialized
in ma_check.c
* extract duplicate functionality from various _my_b_*_read
functions into a common wrapper. Same for _my_b_*_write
* create _my_b_cache_write_r instead of having if's in
_my_b_cache_write (similar to existing _my_b_cache_read and
_my_b_cache_read_r)
* don't call mysql_file_write() from my_b_flush_io_cache(),
call info->write_function() instead
remove some 14-year old code that added support for
LOAD DATA replication to IO_CACHE:
* three callbacks, of which only two were actually used and that
were only needed for LOAD DATA replication but were
tested in every IO_CACHE instance
* an additional opaque void * argument in IO_CACHE, also only
used for LOAD DATA replication, but present everywhere
* the code to close IO_CACHE prematurely in LOAD DATA to have
these callbacks called in the correct order and a long
comment explaining what will happen if IO_CACHE is not
closed prematurely
* a variable to track whether IO_CACHE was closed prematurely
(to avoid double-closing it)
* mysqld_safe: Since wsrep_on variable is mandatory in 10.1, skip wsrep
position recovery if its OFF.
* mysqld: Remove "-wsrep" from server version
* mysqld: Remove wsrep patch version from @@version_comment
* mysqld: Introduce @@wsrep_patch_version
* Extract it into the "encryption_scheme" service.
* Make these engines to use the service, remove duplicate code.
* Change MY_AES_xxx error codes, to return them safely
from encryption_scheme_encrypt/decrypt without conflicting
with ENCRYPTION_SCHEME_KEY_INVALID error

WL#8354 BACKPORT DIGEST IMPROVEMENTS TO MYSQL 5.6
(with the following commits) and related changes in sql/
* no --encryption-algorithm option anymore
* encrypt/decrypt methods in the encryption plugin
* ecnrypt/decrypt methods in the encryption_km service
* file_km plugin has --file-key-management-encryption-algorithm
* debug_km always uses aes_cbc
* example_km changes between aes_cbc and aes_ecb for different key versions
* my_aes.h doesn't compile without my_global.h
* typo in a comment
* redundant condition
* if encryption plugin fails, there's no encryption_key_manager
at plugin deinit time
* encryption plugin tests must run when plugin.so is present,
not when a plugin is active (otherwise the test will be skipped
when plugin fails to initialize).
XID cache is now based on lock-free hash.
Also fixed lf_hash_destroy() to call alloc destructor.
Note that previous implementation had race condition when thread was accessing
XA owned by different thread. This new implementation doesn't fix it either.
Adding a new virtual function MY_CHARSET_HANDLER::copy_abort().
Moving character set specific code into the correspoding implementations
(for simple, multi-byte and mbmaxlen>1 character sets).
file_key_management_plugin is used
Fixed error handling and added disabling InnoDB redo log encryption
if encryption key management plugin is not there.
