branches/zip: Implement ROW_FORMAT=COMPRESSED and ROW_FORMAT=DYNAMIC.
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::check_if_incompatible_data(): Return COMPATIBLE_DATA_NO

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.

branches/zip: Implement ROW_FORMAT=COMPRESSED and ROW_FORMAT=DYNAMIC.
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.

branches/zip: Implement the configuration parameter and settable global
variable innodb_file_format. Implement file format version stamping of
*.ibd files and SYS_TABLES.TYPE.
This change breaks introduces an incompatible change for for
compressed tables. We can do this, as we have not released yet.
innodb-zip.test: Add tests for stricter KEY_BLOCK_SIZE and ROW_FORMAT
checks.
DICT_TF_COMPRESSED_MASK, DICT_TF_COMPRESSED_SHIFT: Replace with
DICT_TF_ZSSIZE_MASK, DICT_TF_ZSSIZE_SHIFT.
DICT_TF_FORMAT_MASK, DICT_TF_FORMAT_SHIFT, DICT_TF_FORMAT_51,
DICT_TF_FORMAT_ZIP: File format version, stored in table->flags,
in the .ibd file header, and in SYS_TABLES.TYPE.
dict_create_sys_tables_tuple(): Write the table flags to SYS_TABLES.TYPE
if the format is at least DICT_TF_FORMAT_ZIP. For old formats
(DICT_TF_FORMAT_51), write DICT_TABLE_ORDINARY as the table type.
DB_TABLE_ZIP_NO_IBD: Remove the error code. The error handling is done
in ha_innodb.cc; as a failsafe measure, dict_build_table_def_step() will
silently clear the compression and format flags instead of returning this
error.
dict_mem_table_create(): Assert that no extra bits are set in the flags.
dict_sys_tables_get_zip_size(): Rename to dict_sys_tables_get_flags().
Check all flag bits, and return ULINT_UNDEFINED if the combination is
unsupported.
dict_boot(): Document the SYS_TABLES columns N_COLS and TYPE.
dict_table_get_format(), dict_table_set_format(),
dict_table_flags_to_zip_size(): New accessors to table->flags.
dtuple_convert_big_rec(): Introduce the auxiliary variables
local_len, local_prefix_len. Store a 768-byte prefix locally
if the file format is less than DICT_TF_FORMAT_ZIP.
dtuple_convert_back_big_rec(): Restore the columns.
srv_file_format: New variable: innodb_file_format.
fil_create_new_single_table_tablespace(): Replace the parameter zip_size
with table->flags.
fil_open_single_table_tablespace(): Replace the parameter zip_size_in_k
with table->flags. Check the flags.
fil_space_struct, fil_space_create(), fil_op_write_log():
Replace zip_size with flags.
fil_node_open_file(): Note a TODO item for InnoDB Hot Backup.
Check that the tablespace flags match.
fil_space_get_zip_size(): Rename to fil_space_get_flags(). Add a
wrapper for fil_space_get_zip_size().
fsp_header_get_flags(): New function.
fsp_header_init_fields(): Replace zip_size with flags.
FSP_SPACE_FLAGS: New name for the tablespace flags. This field used
to be called FSP_PAGE_ZIP_SIZE, or FSP_LOWEST_NO_WRITE. It has always
been written as 0 in MySQL/InnoDB versions 4.1 to 5.1.
MLOG_ZIP_FILE_CREATE: Rename to MLOG_FILE_CREATE2. Add a 32-bit
parameter for the tablespace flags.
ha_innobase::create(): Check the table attributes ROW_FORMAT and
KEY_BLOCK_SIZE. Issue errors if they are inappropriate, or warnings
if the inherited attributes (in ALTER TABLE) will be ignored.
PAGE_ZIP_MIN_SIZE_SHIFT: New constant: the 2-logarithm of PAGE_ZIP_MIN_SIZE.
