Marko Mäkelä	9bc874a594	MDEV-23497 Make ROW_FORMAT=COMPRESSED read-only by default Let us introduce the parameter innodb_read_only_compressed that is ON by default, making any ROW_FORMAT=COMPRESSED tables read-only. I developed the ROW_FORMAT=COMPRESSED format based on Heikki Tuuri's rough design between 2005 and 2008. It might have been a good idea back then, but no proper benchmarks were ever run to validate the design or the implementation. The format has been more or less obsolete for years. It limits innodb_page_size to 16384 bytes (the default), and instant ALTER TABLE is not supported. This is the first step towards deprecating and removing write support for ROW_FORMAT=COMPRESSED tables.	5 years ago
Marko Mäkelä	ac24289e66	MDEV-16328 ALTER TABLE…page_compression_level should not rebuild table The table option page_compression_level is something that only affects future writes, not actually the data format. Therefore, we can allow instant changes of this option. Similarly, the table option page_compressed can be set on a previously uncompressed table without rebuilding the table, because an uncompressed page would be considered valid when reading a page_compressed table. Removing the page_compressed option will continue to require the table to be rebuilt. ha_innobase_inplace_ctx::page_compression_level: The requested page_compression_level at the start of ALTER TABLE, or 0 if page_compressed=OFF. alter_options_need_rebuild(): Renamed from create_option_need_rebuild(). Allow page_compression_level and page_compressed to be changed as above, without rebuilding the table. ha_innobase::check_if_supported_inplace_alter(): Allow ALGORITHM=INSTANT for ALTER_OPTIONS if the table is not to be rebuilt. If rebuild is needed, set ha_alter_info->unsupported_reason. innobase_page_compression_try(): Update SYS_TABLES.TYPE according to the table flags, for an instant change of page_compression_level or page_compressed. commit_cache_norebuild(): Adjust dict_table_t::flags, fil_space_t::flags and (if needed) FSP_SPACE_FLAGS if page_compression_level was specified.	7 years ago
Jan Lindström	f302a3cf9d	MDEV-12593: InnoDB page compression should use lz4_compress_default if available lz4.cmake: Check if shared or static lz4 library has LZ4_compress_default function and if it has define HAVE_LZ4_COMPRESS_DEFAULT. fil_compress_page: If HAVE_LZ4_COMPRESS_DEFAULT is defined use LZ4_compress_default function for compression if not use LZ4_compress_limitedOutput function. Introduced a innodb-page-compression.inc file for page compression tests that will also search .ibd file to verify that pages are compressed (i.e. used search string is not found). Modified page compression tests to use this file. Note that snappy method is not included because of MDEV-12615 InnoDB page compression method snappy mostly does not compress pages that will be fixed on different commit.	9 years ago
Marko Mäkelä	08413254b7	Remove references to innodb_file_format. innodb_file_format=Barracuda is the default in MariaDB 10.2. Do not set it, because the option will be removed in MariaDB 10.3. Also, do not set innodb_file_per_table=1 because it is the default. Note that MDEV-11828 should fix the test innodb.innodb-64k already in 10.1.	9 years ago
Jan Lindström	7b55b67de5	MDEV-7228: innodb.innodb-page_compression_tables, innodb.innodb-page_compression_zip, innodb.innodb_stats_create_on_corrupted fail with embedded server Problem is that tests restart the server and "shutdown_server" looks for pid file # which is not there with embedded mode. Fix tests so that they are not run with embedded mode.	11 years ago
Jan Lindström	b96697d286	MDEV-6648: InnoDB: Add support for 4K sector size if supported New generation hard drives, SSDs and NVM devices support 4K sector size. Supported sector size can be found using fstatvfs() or GetDiskFreeSpace() functions.	11 years ago
Jan Lindström	dbc79ce055	MDEV-6354: Implement a way to read MySQL 5.7.4-labs-tplc page compression format (Fusion-IO). Addeed LZMA and BZIP2 compression methods.	11 years ago
