Fixed by removing writing key version to start of every block that
was encrypted. Instead we will use single key version from log_sys
crypt info.
After this MDEV also blocks writen to row log are encrypted and blocks
read from row log aren decrypted if encryption is configured for the
table.
innodb_status_variables[], struct srv_stats_t
Added status variables for merge block and row log block
encryption and decryption amounts.
Removed ROW_MERGE_RESERVE_SIZE define.
row_merge_fts_doc_tokenize
Remove ROW_MERGE_RESERVE_SIZE
row_log_t
Add index, crypt_tail, crypt_head to be used in case of
encryption.
row_log_online_op, row_log_table_close_func
Before writing a block encrypt it if encryption is enabled
row_log_table_apply_ops, row_log_apply_ops
After reading a block decrypt it if encryption is enabled
row_log_allocate
Allocate temporary buffers crypt_head and crypt_tail
if needed.
row_log_free
Free temporary buffers crypt_head and crypt_tail if they
exist.
row_merge_encrypt_buf, row_merge_decrypt_buf
Removed.
row_merge_buf_create, row_merge_buf_write
Remove ROW_MERGE_RESERVE_SIZE
row_merge_build_indexes
Allocate temporary buffer used in decryption and encryption
if needed.
log_tmp_blocks_crypt, log_tmp_block_encrypt, log_temp_block_decrypt
New functions used in block encryption and decryption
log_tmp_is_encrypted
New function to check is encryption enabled.
Added test case innodb-rowlog to force creating a row log and
verify that operations are done using introduced status
variables.
Added encryption support for online alter table where InnoDB temporary
files are used. Added similar support also for tables containing
full text-indexes.
Made sure that table remains encrypted during discard and import
tablespace.
