+## - statement with a side effect, that fails to insert N twice
+## - a statement rollback is expected (expecting 1 row 1000+N only) in t2
+## - a rollback is performed

 /* ========================================================================
  ======================= TRANSACTIONS ===================================*/
 
+/**
+  Transaction handling in the server
+  ==================================
+
+  In each client connection, MySQL maintains two transactional
+  states:
+  - a statement transaction,
+  - a standard, also called normal transaction.
+
+  Historical note
+  ---------------
+  "Statement transaction" is a non-standard term that comes
+  from the times when MySQL supported BerkeleyDB storage engine.
+
+  First of all, it should be said that in BerkeleyDB auto-commit
+  mode auto-commits operations that are atomic to the storage
+  engine itself, such as a write of a record, and are too
+  high-granular to be atomic from the application perspective
+  (MySQL). One SQL statement could involve many BerkeleyDB
+  auto-committed operations and thus BerkeleyDB auto-commit was of
+  little use to MySQL.
+
+  Secondly, instead of SQL standard savepoints, BerkeleyDB
+  provided the concept of "nested transactions". In a nutshell,
+  transactions could be arbitrarily nested, but when the parent
+  transaction was committed or aborted, all its child (nested)
+  transactions were handled committed or aborted as well.
+  Commit of a nested transaction, in turn, made its changes
+  visible, but not durable: it destroyed the nested transaction,
+  all its changes would become available to the parent and
+  currently active nested transactions of this parent.
+
+  So the mechanism of nested transactions was employed to
+  provide "all or nothing" guarantee of SQL statements
+  required by the standard.
+  A nested transaction would be created at start of each SQL
+  statement, and destroyed (committed or aborted) at statement
+  end. Such nested transaction was internally referred to as
+  a "statement transaction" and gave birth to the term.
+
+  <Historical note ends>
+
+  Since then a statement transaction is started for each statement
+  that accesses transactional tables or uses the binary log.  If
+  the statement succeeds, the statement transaction is committed.
+  If the statement fails, the transaction is rolled back. Commits
+  of statement transactions are not durable -- each such
+  transaction is nested in the normal transaction, and if the
+  normal transaction is rolled back, the effects of all enclosed
+  statement transactions are undone as well.  Technically,
+  a statement transaction can be viewed as a savepoint which is
+  maintained automatically in order to make effects of one
+  statement atomic.
+
+  The normal transaction is started by the user and is ended
+  usually upon a user request as well. The normal transaction
+  encloses transactions of all statements issued between
+  its beginning and its end.
+  In autocommit mode, the normal transaction is equivalent
+  to the statement transaction.
+
+  Since MySQL supports PSEA (pluggable storage engine
+  architecture), more than one transactional engine can be
+  active at a time. Hence transactions, from the server
+  point of view, are always distributed. In particular,
+  transactional state is maintained independently for each
+  engine. In order to commit a transaction the two phase
+  commit protocol is employed.
+
+  Not all statements are executed in context of a transaction.
+  Administrative and status information statements do not modify
+  engine data, and thus do not start a statement transaction and
+  also have no effect on the normal transaction. Examples of such
+  statements are SHOW STATUS and RESET SLAVE.
+
+  Similarly DDL statements are not transactional,
+  and therefore a transaction is [almost] never started for a DDL
+  statement. The difference between a DDL statement and a purely
+  administrative statement though is that a DDL statement always
+  commits the current transaction before proceeding, if there is
+  any.
+
+  At last, SQL statements that work with non-transactional
+  engines also have no effect on the transaction state of the
+  connection. Even though they are written to the binary log,
+  and the binary log is, overall, transactional, the writes
+  are done in "write-through" mode, directly to the binlog
+  file, followed with a OS cache sync, in other words,
+  bypassing the binlog undo log (translog).
+  They do not commit the current normal transaction.
+  A failure of a statement that uses non-transactional tables
+  would cause a rollback of the statement transaction, but
+  in case there no non-transactional tables are used,
+  no statement transaction is started.
+
+  Data layout
+  -----------
+
+  The server stores its transaction-related data in
+  thd->transaction. This structure has two members of type
+  THD_TRANS. These members correspond to the statement and
+  normal transactions respectively:
+
+  - thd->transaction.stmt contains a list of engines
+  that are participating in the given statement
+  - thd->transaction.all contains a list of engines that
+  have participated in any of the statement transactions started
+  within the context of the normal transaction.
+  Each element of the list contains a pointer to the storage
+  engine, engine-specific transactional data, and engine-specific
+  transaction flags.
+
+  In autocommit mode thd->transaction.all is empty.
+  Instead, data of thd->transaction.stmt is
+  used to commit/rollback the normal transaction.
+
+  The list of registered engines has a few important properties:
+  - no engine is registered in the list twice
+  - engines are present in the list a reverse temporal order --
+  new participants are always added to the beginning of the list.
+
+  Transaction life cycle
+  ----------------------
+
+  When a new connection is established, thd->transaction
+  members are initialized to an empty state.
+  If a statement uses any tables, all affected engines
+  are registered in the statement engine list. In
+  non-autocommit mode, the same engines are registered in
+  the normal transaction list.
+  At the end of the statement, the server issues a commit
+  or a roll back for all engines in the statement list.
+  At this point transaction flags of an engine, if any, are
+  propagated from the statement list to the list of the normal
+  transaction.
+  When commit/rollback is finished, the statement list is
+  cleared. It will be filled in again by the next statement,
+  and emptied again at the next statement's end.
+
+  The normal transaction is committed in a similar way
+  (by going over all engines in thd->transaction.all list)
+  but at different times:
+  - upon COMMIT SQL statement is issued by the user
+  - implicitly, by the server, at the beginning of a DDL statement
+  or SET AUTOCOMMIT={0|1} statement.
+
+  The normal transaction can be rolled back as well:
+  - if the user has requested so, by issuing ROLLBACK SQL
+  statement
+  - if one of the storage engines requested a rollback
+  by setting thd->transaction_rollback_request. This may
+  happen in case, e.g., when the transaction in the engine was
+  chosen a victim of the internal deadlock resolution algorithm
+  and rolled back internally. When such a situation happens, there
+  is little the server can do and the only option is to rollback
+  transactions in all other participating engines.  In this case
+  the rollback is accompanied by an error sent to the user.
+
+  As follows from the use cases above, the normal transaction
+  is never committed when there is an outstanding statement
+  transaction. In most cases there is no conflict, since
+  commits of the normal transaction are issued by a stand-alone
+  administrative or DDL statement, thus no outstanding statement
+  transaction of the previous statement exists. Besides,
+  all statements that manipulate with the normal transaction
+  are prohibited in stored functions and triggers, therefore
+  no conflicting situation can occur in a sub-statement either.
+  The remaining rare cases when the server explicitly has
+  to commit the statement transaction prior to committing the normal
+  one cover error-handling scenarios (see for example
+  SQLCOM_LOCK_TABLES).
+
+  When committing a statement or a normal transaction, the server
+  either uses the two-phase commit protocol, or issues a commit
+  in each engine independently. The two-phase commit protocol
+  is used only if:
+  - all participating engines support two-phase commit (provide
+    handlerton::prepare PSEA API call) and
+  - transactions in at least two engines modify data (i.e. are
+  not read-only).
+
+  Note that the two phase commit is used for
+  statement transactions, even though they are not durable anyway.
+  This is done to ensure logical consistency of data in a multiple-
+  engine transaction.
+  For example, imagine that some day MySQL supports unique
+  constraint checks deferred till the end of statement. In such
+  case a commit in one of the engines may yield ER_DUP_KEY,
+  and MySQL should be able to gracefully abort statement
+  transactions of other participants.
+
+  After the normal transaction has been committed,
+  thd->transaction.all list is cleared.
+
+  When a connection is closed, the current normal transaction, if
+  any, is rolled back.
+
+  Roles and responsibilities
+  --------------------------
+
+  The server has no way to know that an engine participates in
+  the statement and a transaction has been started
+  in it unless the engine says so. Thus, in order to be
+  a part of a transaction, the engine must "register" itself.
+  This is done by invoking trans_register_ha() server call.
+  Normally the engine registers itself whenever handler::external_lock()
+  is called. trans_register_ha() can be invoked many times: if
+  an engine is already registered, the call does nothing.
+  In case autocommit is not set, the engine must register itself
+  twice -- both in the statement list and in the normal transaction
+  list.
+  In which list to register is a parameter of trans_register_ha().
+
+  Note, that although the registration interface in itself is
+  fairly clear, the current usage practice often leads to undesired
+  effects. E.g. since a call to trans_register_ha() in most engines
+  is embedded into implementation of handler::external_lock(), some
+  DDL statements start a transaction (at least from the server
+  point of view) even though they are not expected to. E.g.
+  CREATE TABLE does not start a transaction, since
+  handler::external_lock() is never called during CREATE TABLE. But
+  CREATE TABLE ... SELECT does, since handler::external_lock() is
+  called for the table that is being selected from. This has no
+  practical effects currently, but must be kept in mind
+  nevertheless.
+
+  Once an engine is registered, the server will do the rest
+  of the work.
+
+  During statement execution, whenever any of data-modifying
+  PSEA API methods is used, e.g. handler::write_row() or
+  handler::update_row(), the read-write flag is raised in the
+  statement transaction for the involved engine.
+  Currently All PSEA calls are "traced", and the data can not be
+  changed in a way other than issuing a PSEA call. Important:
+  unless this invariant is preserved the server will not know that
+  a transaction in a given engine is read-write and will not
+  involve the two-phase commit protocol!
+
+  At the end of a statement, server call
+  ha_autocommit_or_rollback() is invoked. This call in turn
+  invokes handlerton::prepare() for every involved engine.
+  Prepare is followed by a call to handlerton::commit_one_phase()
+  If a one-phase commit will suffice, handlerton::prepare() is not
+  invoked and the server only calls handlerton::commit_one_phase().
+  At statement commit, the statement-related read-write engine
+  flag is propagated to the corresponding flag in the normal
+  transaction.  When the commit is complete, the list of registered
+  engines is cleared.
+
+  Rollback is handled in a similar fashion.
+
+  Additional notes on DDL and the normal transaction.
+  ---------------------------------------------------
+
+  DDLs and operations with non-transactional engines
+  do not "register" in thd->transaction lists, and thus do not
+  modify the transaction state. Besides, each DDL in
+  MySQL is prefixed with an implicit normal transaction commit
+  (a call to end_active_trans()), and thus leaves nothing
+  to modify.
+  However, as it has been pointed out with CREATE TABLE .. SELECT,
+  some DDL statements can start a *new* transaction.
+
+  Behaviour of the server in this case is currently badly
+  defined.
+  DDL statements use a form of "semantic" logging
+  to maintain atomicity: if CREATE TABLE .. SELECT failed,
+  the newly created table is deleted.
+  In addition, some DDL statements issue interim transaction
+  commits: e.g. ALTER TABLE issues a commit after data is copied
+  from the original table to the internal temporary table. Other
+  statements, e.g. CREATE TABLE ... SELECT do not always commit
+  after itself.
+  And finally there is a group of DDL statements such as
+  RENAME/DROP TABLE that doesn't start a new transaction
+  and doesn't commit.
+
+  This diversity makes it hard to say what will happen if
+  by chance a stored function is invoked during a DDL --
+  whether any modifications it makes will be committed or not
+  is not clear. Fortunately, SQL grammar of few DDLs allows
+  invocation of a stored function.
+
+  A consistent behaviour is perhaps to always commit the normal
+  transaction after all DDLs, just like the statement transaction
+  is always committed at the end of all statements.
