row_search_for_mysql(): When a secondary index record might not be
visible in the current transaction's read view and we consult the
clustered index and optionally some undo log records, return the
relevant columns of the clustered index record to MySQL instead of the
secondary index record.
ibuf_insert_to_index_page_low(): New function, refactored from
ibuf_insert_to_index_page().
ibuf_insert_to_index_page(): When we are inserting a record in place
of a delete-marked record and some fields of the record differ, update
that record just like row_ins_sec_index_entry_by_modify() would do.
btr_cur_update_alloc_zip(): Make the function public.
mysql_row_templ_t: Add clust_rec_field_no.
row_sel_store_mysql_rec(), row_sel_push_cache_row_for_mysql(): Add the
flag rec_clust, for returning data at clust_rec_field_no instead of
rec_field_no. Resurrect the debug assertion that the record not be
marked for deletion. (Bug #55626)
[UNIV_DEBUG || UNIV_IBUF_DEBUG] ibuf_debug, buf_page_get_gen(),
buf_flush_page_try():
Implement innodb_change_buffering_debug=1 for evicting pages from the
buffer pool, so that change buffering will be attempted more
frequently.
columns
When the server crashes after a record stub has been inserted and
before all its off-page columns have been written, the record will
contain incomplete off-page columns after crash recovery. Such records
may only be accessed at the READ UNCOMMITTED isolation level or when
rolling back a recovered transaction in recv_recovery_rollback_active().
Skip these records at the READ UNCOMMITTED isolation level.
TODO: Add assertions for checking the above assumptions hold when an
incomplete BLOB is encountered.
btr_rec_copy_externally_stored_field(): Return NULL if the field is
incomplete.
row_prebuilt_t::templ_contains_blob: Clarify what "BLOB" means in this
context. Hint: MySQL BLOBs are not the same as InnoDB BLOBs.
row_sel_store_mysql_rec(): Return FALSE if not all columns could be
retrieved. Previously this function always returned TRUE. Assert that
the record is not delete-marked.
row_sel_push_cache_row_for_mysql(): Return FALSE if not all columns
could be retrieved.
row_search_for_mysql(): Skip records containing incomplete off-page
columns. Assert that the transaction isolation level is READ
UNCOMMITTED.

In semi-consistent read, only unlock freshly locked non-matching records.
lock_rec_lock_fast(): Return LOCK_REC_SUCCESS,
LOCK_REC_SUCCESS_CREATED, or LOCK_REC_FAIL instead of TRUE/FALSE.
enum db_err: Add DB_SUCCESS_LOCKED_REC for indicating a successful
operation where a record lock was created.
lock_sec_rec_read_check_and_lock(),
lock_clust_rec_read_check_and_lock(), lock_rec_enqueue_waiting(),
lock_rec_lock_slow(), lock_rec_lock(), row_ins_set_shared_rec_lock(),
row_ins_set_exclusive_rec_lock(), sel_set_rec_lock(),
row_sel_get_clust_rec_for_mysql(): Return DB_SUCCESS_LOCKED_REC if a
new record lock was created. Adjust callers.
row_unlock_for_mysql(): Correct the function documentation.
row_prebuilt_t::new_rec_locks: Correct the documentation.
Also make InnoDB thinks that /*/ only starts a comment. (Bug #53644).
This fixes the bugs in the InnoDB Plugin.
ha_innodb.h: Use trx_query_string() instead of trx_query() when
available (MySQL 5.1.42 or later).
innobase_get_stmt(): New function, to retrieve the currently running
SQL statement.
struct trx_struct: Remove mysql_query_str. Use innobase_get_stmt() instead.
dict_strip_comments(): Add and observe the parameter sql_length. Treat
/*/ as the start of a comment.
dict_create_foreign_constraints(), row_table_add_foreign_constraints():
Add the parameter sql_length.

branches/zip: Clean up CHECK TABLE error handling. (Issue #220)
ha_innobase::change_active_index(): Clean up code formatting.
ha_innobase::check(): Incorporate the code from
row_check_table_for_mysql(). Report errors to the client connection
instead of writing them to the error log.
row_check_table_for_mysql(): Remove.
row_check_index_for_mysql(): Renamed from row_scan_and_check_index().
Let the caller initialize prebuilt, and assume that the index is usable.

branches/zip: Drop temporary tables at startup.
This addresses the third aspect of Bug #41609.
row_mysql_drop_temp_tables(): New function, to drop all temporary
tables. These can be distinguished by the least significant bit of
MIX_LEN. However, we will skip ROW_FORMAT=REDUNDANT tables, because in
the records for those tables, that bit may be garbage.
recv_recovery_from_checkpoint_finish(): Invoke
row_mysql_drop_temp_tables(). Normally, if the .frm files for the
temporary tables exist at startup, MySQL will ask InnoDB to drop the
temporary tables. However, if the files are deleted, for instance, by
the boot scripts of the operating system, the tables would remain in
the InnoDB data dictionary unless someone digs them up by
innodb_table_monitor and creates .frm files for dropping the tables.
