In original code, sometimes one got an automatic DEFAULT value in some cases, in other cases not.
For example:
create table t1 (a int primary key) - No default
create table t2 (a int, primary key(a)) - DEFAULT 0
create table t1 SELECT .... - Default for all fields, even if they where defined as NOT NULL
ALTER TABLE ... MODIFY could sometimes add an unexpected DEFAULT value.
The patch is quite big because we had some many test cases that used
CREATE ... SELECT or CREATE ... (...PRIMARY KEY(xxx)) which doesn't have an automatic DEFAULT anymore.
Other things:
- Removed warnings from InnoDB when waiting from semaphore (got this when testing things with --big)
Introduce a new dummy INFORMATION_SCHEMA.CHANGED_PAGE_BITMAPS table to XtraDB
with reset_table callback to allow FLUSH NO_WRITE_TO_BINLOG CHANGED_PAGE_BITMAPS
to be called from innobackupex.
Problem was that information schema tables innodb_tablespaces_encryption and
innodb_tablespaces_scrubbing where missing required check is InnoDB enabled
or not.
With changes:
* update tests to pass (new encryption/encryption_key_id syntax).
* not merged the code that makes engine aware of the encryption mode
(CRYPT_SCHEME_1_CBC, CRYPT_SCHEME_1_CTR, storing it on disk, etc),
because now the encryption plugin is handling it.
* compression+encryption did not work in either branch before the
merge - and it does not work after the merge. it might be more
broken after the merge though - some of that code was not merged.
* page checksumming code was not moved (moving of page checksumming
from fil_space_encrypt() to fil_space_decrypt was not merged).
* restored deleted lines in buf_page_get_frame(), otherwise
innodb_scrub test failed.
if XA PREPARE transactions hold explicit locks.
innobase_shutdown_for_mysql(): Call trx_sys_close() before lock_sys_close()
(and dict_close()) so that trx_free_prepared() will see all locks intact.

The test case was missing --source include/wait_for_binlog_checkpoint.inc.
So it could occasionally fail if the checkpoint managed to occur just at the
right point in time between fetching the two binlog positions to compare.
Step 3:
-- Make encrytion_algorithm changeable by SUPER
-- Remove AES_ECB method from encryption_algorithms
-- Support AES method change by storing used method on InnoDB/XtraDB objects
-- Store used AES method to crypt_data as different crypt types
-- Store used AES method to redo/undo logs and checkpoint
-- Store used AES method on every encrypted page after key_version
-- Add test
Analysis: MySQL table definition contains also virtual columns. Similarly,
index fielnr references MySQL table fields. However, InnoDB table definition
does not contain virtual columns. Therefore, when matching MySQL key fieldnr
we need to use actual column name to find out referenced InnoDB dictionary
column name.
Fix: Add new function to match MySQL index key columns to InnoDB dictionary.
innodb_buffer_pool_pages_total depends on page size. On Power8 it is 65k
compared to 4k on Intel. As we round allocations on page size we may get
slightly more memory for buffer pool.
Sort XA RECOVER as rows order depend on endianness.
Two problems:
- Read/Write outside of buffer at memcpy() because of incorrect parameters
. OPENSSL_assert(EVP_CIPHER_CTX_iv_length(&ctx.ctx) == iv_length); // ECB does not use IV, thus incorrect assertion
Added:
mysql-test/include/encryption_algorithms.combinations to run tests with methods cbc, ecb and ctr in
those systems where they are available (see suite.pm).
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.

Add error handling when disk full situation happens and
intentionally bring server down with stacktrace because
on all cases InnoDB can't continue anyway.
