Add innodb_locks.lock_data column and some relevant tests.
For record locks this column represents the ordering fields of the
locked row in a human readable, SQL-valid, format.

The size of the buffer pool can be one page smaller than the requested
size when os_mem_alloc_large() returns something that is not
aligned by UNIV_PAGE_SIZE. This test may still fail on systems with
a big os_large_page_size.
Unfortunately, the patch seems to prevent MySQL from utilizing secondary
indexes in the ORDER BY clauses. Thus, the test no longer checks if newly
created indexes are well-formed.

Fixed bug#28404.
This patch adds cost estimation for the queries with ORDER BY / GROUP BY
and LIMIT.
If there was a ref/range access to the table whose rows were required
to be ordered in the result set the optimizer always employed this access
though a scan by a different index that was compatible with the required
order could be cheaper to produce the first L rows of the result set.
Now for such queries the optimizer makes a choice between the cheapest
ref/range accesses not compatible with the given order and index scans
compatible with it.
that row_merge_blocks() will have some work to do when
row_merge_block_t is shrunk to 8192 bytes.
Currently, this will cause a debug assertion failure, because
row_merge_cmp() is considering all columns, not just the unique ones.
fast index creation.
innobase_convert_tablename(): New function, to remove the filename
encoding of a database and table name.
ha_innobase::add_index(): Invoke innobase_convert_tablename() before
calling my_error().
innodb-index.result: Update the error messages.
FOREIGN KEY constraints. At the moment, MySQL will rebuild the entire
table and indexes when such constraints are added or removed, even though
the constraints do not affect the storage format of the data.
innodb-index.test: Add some test cases for FOREIGN KEY constraints.
row_merge_rename_tables(): New function,
adapted from row_rename_table_for_mysql().
ha_innobase::add_index(): Use row_merge_rename_tables().
(PRIMARY KEY or UNIQUE INDEX on NOT NULL columns).
innodb-index.test: Remove the --replace_regex directives. Replace correct
values to the "Duplicate entry" messages. This will cause the test to
fail until we somehow return the duplicate key values to MySQL.
Add test cases for creating or dropping UNIQUE INDEX or PRIMARY KEY.
innobase_copy_index_def(): Allow the function to copy a clustered index
definition to a secondary one (UNIQUE INDEX).
innobase_create_key_def(): Check the NOT NULL flag from the correct
place. Copy the clustered index if it is a UNIQUE INDEX.
ha_innobase::prepare_drop_index(): Refuse to drop the clustered index.
The creation of the primary key does not work. We will have to flag
externally stored columns and copy the externally stored part from
the old table.
row_build_index_for_mysql(): Rename to row_merge_build_indexes().
Move from row0mysql.c to row0merge.c.
Remove private declarations from row0merge.h. Make many functions static
in row0merge.c.
cmp_rec_rec_simple(): A new comparison function.
dict_index_get_min_size(): New function.
OS_FILE_FROM_FD(fd): A macro for converting from int to os_file_t.
rec_convert_dtuple_to_rec_comp(): Make the interface lower-level.
rec_get_converted_size_comp(): Return also extra_size.
UT_SORT_FUNCTION_BODY(): Remove reference to an obsolete test program.
row_rec_to_index_entry_low(): New function.
row0merge.c: Implement merge sort based on file streams instead of
fixed-size blocks. Sort the small blocks as arrays of dfield_t*,
because it is faster than invoking rec_get_offsets() for every
comparison.
innobase_create_index_def(): Add parameter new_primary.
innobase_copy_index_def(): Simplify the documented algorithm,
and try to implement it properly.
innodb-index.test: Replace CHECKSUM TABLE with something more stable and
useful. The test passes on an older BitKeeper snapshot:
ChangeSet@1.2475.18.9, 2007-05-08 11:16:41+02:00, jbruehe@mysql.com +1 -0
Raise version number after cloning 5.1.18-beta
But it fails on a newer one where the statement
alter table t1 add primary key (a), add key (b(20));
results in fast index creation:
ChangeSet@1.2500.1.40, 2007-06-01 20:06:13+04:00, kostja@bodhi.(none) +2 -0
Merge bodhi.(none):/opt/local/work/mysql-5.0-runtime
into bodhi.(none):/opt/local/work/mysql-5.1-runtime
MERGE: 1.1810.2984.14
innodb.test: The error code 1540 has been renumbered to 1542.
innodb.result: Adjust the expected value of Innodb_buffer_pool_pages_total.
Something may have changed in the BLOB handling in branches/zip.
ha_innodb.cc: Add ha_innobase:: prefix to some DBUG_ENTER macros.
row_merge_create_temporary_table(): Free the heap only after invoking
row_create_table_for_mysql(). The table->col_names points to the heap
until the system columns are added by row_create_table_for_mysql().
TODO: use the filename-safe encoding in temporary table names. Test
extensively under Valgrind and fix all errors found. Eliminate
merge_rec_t and rewrite row0merge.c to write the records directly to
the merge blocks.
