Merge change from MySQL (this fixes the failing innodb test):
ChangeSet@1.1810.3601.4, 2008-02-07 02:33:21+04:00, gshchepa@host.loc +9 -0
Fixed bug#30059.
Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
any mode.
Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.
Binary-encoded string/BLOB columns are not affected.

Fix Bug#36169 create innodb compressed table with too large row size crashed
Sometimes it is possible that
row_drop_table_for_mysql(index->table_name, trx, FALSE); is invoked in
row_create_index_for_mysql() when the index object is freed so copy the
table name to a safe place beforehand and use the copy.

Throw warnings, not errors for wrong ROW_FORMAT or KEY_BLOCK_SIZE,
so that any table dump can be loaded.
As of this change, InnoDB supports the following table formats:
ROW_FORMAT=REDUNDANT
the only format before MySQL/InnoDB 5.0.3
ROW_FORMAT=COMPACT
the new default format of MySQL/InnoDB 5.0.3
ROW_FORMAT=DYNAMIC
uncompressed, no prefix in the clustered index record for BLOBs
ROW_FORMAT=COMPRESSED
like ROW_FORMAT=DYNAMIC, but zlib compressed B-trees and BLOBs;
the compressed page size is specified by KEY_BLOCK_SIZE in
kilobytes (1, 2, 4, 8, or 16; default 8)
KEY_BLOCK_SIZE=1, 2, 4, 8, or 16: implies ROW_FORMAT=COMPRESSED;
ignored if ROW_FORMAT is not COMPRESSED
KEY_BLOCK_SIZE=anything else: ignored
The InnoDB row format is displayed in the 4th column (Row_format) of
the output of SHOW TABLE STATUS. The Create_options column may show
ROW_FORMAT= and KEY_BLOCK_SIZE=, but they do not necessarily have
anything to do with InnoDB.
The table format can also be queried like this:
SELECT table_schema, table_name, row_format
FROM information_schema.tables
WHERE engine='innodb' and row_format in ('Compressed','Dynamic');
When Row_format='Compressed', KEY_BLOCK_SIZE should usually correspond
to the compressed page size. But the .frm file could be manipulated
to show any KEY_BLOCK_SIZE.
For some reason, INFORMATION_SCHEMA.TABLES.CREATE_OPTIONS does not
include KEY_BLOCK_SIZE. It does include row_format (spelled in
lowercase). This looks like a MySQL bug, because the table
INFORMATION_SCHEMA.TABLES probably tries to replace SHOW TABLE STATUS.
I reported this as Bug #35275 <http://bugs.mysql.com/35275>.
ha_innobase::get_row_type(): Add ROW_TYPE_COMPRESSED, ROW_TYPE_DYNAMIC.
ha_innobase::create(): Implement ROW_FORMAT=COMPRESSED and
ROW_FORMAT=DYNAMIC. Do not throw errors for wrong ROW_FORMAT or
KEY_BLOCK_SIZE, but issue warnings instead.
ha_innobase::check_if_incompatible_data(): Return COMPATIBLE_DATA_NO
if KEY_BLOCK_SIZE has been specified.
innodb.result: Adjust the result for the warning issued for ROW_FORMAT=FIXED.
innodb-zip.test: Add tests. Query INFORMATION_SCHEMA.TABLES for ROW_FORMAT.
innodb.result, innodb.test: Revert the changes in r2145.
The tests that were removed by MySQL
ChangeSet@1.2598.2.6 2007-11-06 15:42:58-07:00 tsmith@hindu.god
were moved to a new test, innodb_autoinc_lock_mode_zero, which is
kept in the MySQL BitKeeper tree.
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.
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.
