Apply innodb-5.0-* snapshots: ss1489 and ss1547.
Fixes:
Bug#9709: InnoDB inconsistensy causes "Operating System Error 32/33"
Bug#22819: SHOW INNODB STATUS crashes the server with an assertion failure under high load
Bug#25645: Assertion failure in file srv0srv.c
Bug#27294: insert into ... select ... causes crash with innodb_locks_unsafe_for_binlog=1
Bug#28138: indexing column prefixes produces corruption in InnoDB
Apply the following InnoDB snapshots:
innodb-5.0-ss1319
innodb-5.0-ss1331
innodb-5.0-ss1333
innodb-5.0-ss1341
Fixes:
- Bug #21409: Incorrect result returned when in READ-COMMITTED with query_cache ON
At low transaction isolation levels we let each consistent read set
its own snapshot.
- Bug #23666: strange Innodb_row_lock_time_% values in show status; also millisecs wrong
On Windows ut_usectime returns secs and usecs relative to the UNIX
epoch (which is Jan, 1 1970).
- Bug #25494: LATEST DEADLOCK INFORMATION is not always cleared
lock_deadlock_recursive(): When the search depth or length is exceeded,
rewind lock_latest_err_file and display the two transactions at the
point of aborting the search.
- Bug #25927: Foreign key with ON DELETE SET NULL on NOT NULL can crash server
Prevent ALTER TABLE ... MODIFY ... NOT NULL on columns for which
there is a foreign key constraint ON ... SET NULL.
- Bug #26835: Repeatable corruption of utf8-enabled tables inside InnoDB
The bug could be reproduced as follows:
Define a table so that the first column of the clustered index is
a VARCHAR or a UTF-8 CHAR in a collation where sequences of bytes
of differing length are considered equivalent.
Insert and delete a record. Before the delete-marked record is
purged, insert another record whose first column is of different
length but equivalent to the first record. Under certain conditions,
the insertion can be incorrectly performed as update-in-place.
Likewise, an operation that could be done as update-in-place can
unnecessarily be performed as delete and insert, but that would not
cause corruption but merely degraded performance.

Applied innodb-5.0-ss1040 and innodb-5.0-ss1099 snapshots.
Bugs fixed:
- Bug #21468: InnoDB crash during recovery with corrupted data pages: XA bug?
- Bug #24299: Identifiers in foreign keys cannot contain U+0160, U+0360, ..., U+FF60
- Bug #24386: Performance degradation caused by instrumentation in mutex_struct
- Bug #24712: SHOW TABLE STATUS for file-per-table showing incorrect time fields
This ChangeSet will be null-merged to mysql-5.1.
Bugs fixed:
- Bug #21638: InnoDB: possible segfault in page_copy_rec_list_end_no_locks
If prefix_len is specified, write it to the insert buffer instead of type->len
- bug #10746: InnoDB: Error: stored_select_lock_type is 0 inside ::start_stmt()!
INSERT ... SELECT uses LOCK_NONE in innodb_locks_unsafe_for_binlog mode, so do
not check for LOCK_X or LOCK_S in start_stmt()
Fix BUG#16814: "SHOW INNODB STATUS format error in LATEST FOREIGN KEY ERROR section"
Add a missing newline to the LAST FOREIGN KEY ERROR section in SHOW INNODB STATUS
output.
Fix BUG#18934: "InnoDB crashes when table uses column names like DB_ROW_ID".
Refuse tables that use reserved column names.
Fixed bugs:
#16814: SHOW INNODB STATUS format error in LATEST FOREIGN KEY ERROR section
dict_foreign_key_error_report(): Always print a newline after invoking
dict_print_info_on_foreign_key_in_create_format().
#16827: Better InnoDB error message if ibdata files omitted from my.cnf.
#17126: CHECK TABLE on InnoDB causes a short hang during check of adaptive hash.
CHECK TABLE blocking other queries, by releasing the btr_search_latch
periodically during the adaptive hash table validation.
#17405: Valgrind: conditional jump or move depends on uninitialised valuesw.
buf_block_init(): Reset magic_n, buf_fix_count, and io_fix to avoid testing
uninitialised variables.
#18077: InnoDB uses full explicit table locks in stored FUNCTION.
#18238: When locks exhaust the buffer pool, InnoDB does not roll back the trx.
Check in pessimistic insert and update if the buffer pool is exhausted by locks.
#18252: Disk space leaks in updates of InnoDB BLOB rows.
btr_cur_pessimistic_update(): Invoke rec_get_offset() after rec_set_field_extern_bits().
btr_store_big_rec_extern_fields(): Note that offsets will no longer be valid
after calling this function.
#18283: When InnoDB returns error 'lock table full', MySQL can write to binlog too much.
#18384: InnoDB memory leak on duplicate key errors if row has many columns.
row_ins_duplicate_error_in_clust(): Call mem_heap_free(heap) at func_exit if needed.
#18350: Use consistent read in CREATE ... SELECT .. if innodb_locks_unsafe_for_binlog is used.
Fixed bugs:
BUG#15991: "innodb-file-per-table + symlink database + rename = crash"
BUG#15650: "DELETE with LEFT JOIN crashes server"
BUG#15308: "Problem of Order with Enum Column in Primary Key"
BUG#14189: "VARBINARY and BINARY variables: trailing space ignored"

Changes from the innodb-5.0-ss92 snapshot.
Do not call os_file_create_tmpfile() at runtime. Instead, create
all tempfiles at startup and guard access to them with mutexes.
table' lockup".
Changes from the innodb-4.1-ss11 snapshot.
Do not call os_file-create_tmpfile() at runtime. Instead, create
a tempfile at startup and guard access to it with a mutex.
Also, fix bugs:
10511: "Wrong padding of UCS2 CHAR columns in ON UPDATE CASCADE";
13778: "If FOREIGN_KEY_CHECKS=0, one can create inconsistent FOREIGN
KEYs". When FOREIGN_KEY_CHECKS=0 we still need to check that
datatypes between foreign key references are compatible.
Also, added test cases (also for bug 9802).
to crash".
Changes from snapshot innodb-5.0-ss52.
Note that buf_block_t::index should be protected by btr_search_latch
or an s-latch or x-latch on the index page.
btr_search_drop_page_hash_index(): Read block->index while holding
btr_search_latch and use the cached value in the loop. Remove some
redundant assertions.
Also fix 13778. When FOREIGN_KEY_CHECKS=0 we still need to check that
datatypes between foreign key references are compatible.
Also added test cases to 9802.
Add a sanity check to page_rec_is_comp; a new univ.i macro UNIV_RELEASE_NOT_YET_STABLE controls such sanity checks that we will remove after the release is stable enough
Do not use __builtin_expect etc. with the Intel ICC compiler, as the compiler crashed in btr0cur.c; the patch was submitted by Axel Schwenke (Bug #11510)
