Latching strategy of the InnoDB B-tree
--------------------------------------
A tree latch protects all non-leaf nodes of the tree. Each node of a tree
also has a latch of its own.
A B-tree operation normally first acquires an S-latch on the tree. It
searches down the tree and releases the tree latch when it has the
leaf node latch. To save CPU time we do not acquire any latch on
non-leaf nodes of the tree during a search, those pages are only bufferfixed.
If an operation needs to restructure the tree, it acquires an X-latch on
the tree before searching to a leaf node. If it needs, for example, to
split a leaf,
(1) InnoDB decides the split point in the leaf,
(2) allocates a new page,
(3) inserts the appropriate node pointer to the first non-leaf level,
(4) releases the tree X-latch,
(5) and then moves records from the leaf to the new allocated page.

Node pointers
-------------
Leaf pages of a B-tree contain the index records stored in the
tree. On levels n > 0 we store 'node pointers' to pages on level
n - 1. For each page there is exactly one node pointer stored:
thus the our tree is an ordinary B-tree, not a B-link tree.
A node pointer contains a prefix P of an index record. The prefix
is long enough so that it determines an index record uniquely.
The file page number of the child page is added as the last
field. To the child page we can store node pointers or index records
which are >= P in the alphabetical order, but < P1 if there is
a next node pointer on the level, and P1 is its prefix.

If a node pointer with a prefix P points to a non-leaf child,
Added Innobase to source distribution
2001-02-17 13:19:19 +01:00
then the leftmost record in the child must have the same
prefix P. If it points to a leaf node, the child is not required
to contain any record with a prefix equal to P. The leaf case
is decided this way to allow arbitrary deletions in a leaf node
without touching upper levels of the tree.
We have predefined a special minimum record which we
define as the smallest record in any alphabetical order.
A minimum record is denoted by setting a bit in the record
header. A minimum record acts as the prefix of a node pointer
which points to a leftmost node on any level of the tree.
File page allocation
--------------------
In the root node of a B-tree there are two file segment headers.
The leaf pages of a tree are allocated from one file segment, to
make them consecutive on disk if possible. From the other file segment
we allocate pages for the non-leaf levels of the tree.

Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier().

Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined.

Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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.

Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock.

Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers.

Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB.

Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined.

Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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.

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile.

The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier().

Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined.

Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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.

Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #13778: "If FOREIGN_KEY_CHECKS=0, one can create inconsistent FOREIGN KEYs".

The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB. The function is only being called #ifdef UNIV_IBUF_DEBUG. * innodb.result Adjust the results for changes in the foreign key error messages. * mem0mem.c|h New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat(). * os0file.c Check the page trailers also after writing to disk. This improves chances of diagnosing bug 18886. os_file_check_page_trailers(): New function for checking that the two copies of the LSN stamped on the page match. os_aio_simulated_handle(): Call os_file_check_page_trailers() before and after os_file_write(). * row0mysql.c Move trx_commit_for_mysql(trx) calls before calls to row_mysql_unlock_data_dictionary(trx) (bug 19727). * row0sel.c row_fetch_print(): Handle SQL NULL values without crashing. row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field when handling an externally stored column. Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined. This should allow the compiler to generate more compact code for assertions. * ut0list.c|h Add ib_list_create_heap().

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Applied innodb-5.1-ss594 snapshot. Fixed BUG#19542 "InnoDB doesn't increase the Handler_read_prev couter". Fixed BUG#19609 "Case sensitivity of innodb_data_file_path gives stupid error". Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers. New: innobase_convert_from_table_id(), innobase_convert_from_id(), innobase_convert_from_filename(), innobase_get_charset. dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(), dict_skip_word(), dict_create_foreign_constraints_low(): Add parameter 'cs' so that isspace() can be replaced with my_isspace(), whose operation depends on the connection character set. dict_scan_id(): Convert identifier to UTF-8. dict_str_starts_with_keyword(): New extern function, to replace dict_accept() in row_search_for_mysql(). mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier(). ha_innobase::create(): Remove the thd->convert_strin() call. Pass the statement to InnoDB in the connection character set and let InnoDB convert the identifier to UTF-8. * Add max_row_size to dict_table_t. * btr0cur.c btr_copy_externally_stored_field(): Only set the 'offset' variable when needed. * buf0buf.c buf_page_io_complete(): Write to the error log if the page number or the space id o the disk do not match those in memory. Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB. The function is only being called #ifdef UNIV_IBUF_DEBUG. * innodb.result Adjust the results for changes in the foreign key error messages. * mem0mem.c|h New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat(). * os0file.c Check the page trailers also after writing to disk. This improves chances of diagnosing bug 18886. os_file_check_page_trailers(): New function for checking that the two copies of the LSN stamped on the page match. os_aio_simulated_handle(): Call os_file_check_page_trailers() before and after os_file_write(). * row0mysql.c Move trx_commit_for_mysql(trx) calls before calls to row_mysql_unlock_data_dictionary(trx) (bug 19727). * row0sel.c row_fetch_print(): Handle SQL NULL values without crashing. row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field when handling an externally stored column. Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined. This should allow the compiler to generate more compact code for assertions. * ut0list.c|h Add ib_list_create_heap().

Applied innodb-5.1-ss594 snapshot. Fixed BUG#19542 "InnoDB doesn't increase the Handler_read_prev couter". Fixed BUG#19609 "Case sensitivity of innodb_data_file_path gives stupid error". Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers. New: innobase_convert_from_table_id(), innobase_convert_from_id(), innobase_convert_from_filename(), innobase_get_charset. dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(), dict_skip_word(), dict_create_foreign_constraints_low(): Add parameter 'cs' so that isspace() can be replaced with my_isspace(), whose operation depends on the connection character set. dict_scan_id(): Convert identifier to UTF-8. dict_str_starts_with_keyword(): New extern function, to replace dict_accept() in row_search_for_mysql(). mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier(). ha_innobase::create(): Remove the thd->convert_strin() call. Pass the statement to InnoDB in the connection character set and let InnoDB convert the identifier to UTF-8. * Add max_row_size to dict_table_t. * btr0cur.c btr_copy_externally_stored_field(): Only set the 'offset' variable when needed. * buf0buf.c buf_page_io_complete(): Write to the error log if the page number or the space id o the disk do not match those in memory. Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB. The function is only being called #ifdef UNIV_IBUF_DEBUG. * innodb.result Adjust the results for changes in the foreign key error messages. * mem0mem.c|h New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat(). * os0file.c Check the page trailers also after writing to disk. This improves chances of diagnosing bug 18886. os_file_check_page_trailers(): New function for checking that the two copies of the LSN stamped on the page match. os_aio_simulated_handle(): Call os_file_check_page_trailers() before and after os_file_write(). * row0mysql.c Move trx_commit_for_mysql(trx) calls before calls to row_mysql_unlock_data_dictionary(trx) (bug 19727). * row0sel.c row_fetch_print(): Handle SQL NULL values without crashing. row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field when handling an externally stored column. Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware.

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers.

Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG.

Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined.

Applied innodb-5.1-ss594 snapshot. Fixed BUG#19542 "InnoDB doesn't increase the Handler_read_prev couter". Fixed BUG#19609 "Case sensitivity of innodb_data_file_path gives stupid error". Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers. New: innobase_convert_from_table_id(), innobase_convert_from_id(), innobase_convert_from_filename(), innobase_get_charset. dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(), dict_skip_word(), dict_create_foreign_constraints_low(): Add parameter 'cs' so that isspace() can be replaced with my_isspace(), whose operation depends on the connection character set. dict_scan_id(): Convert identifier to UTF-8. dict_str_starts_with_keyword(): New extern function, to replace dict_accept() in row_search_for_mysql(). mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier(). ha_innobase::create(): Remove the thd->convert_strin() call. Pass the statement to InnoDB in the connection character set and let InnoDB convert the identifier to UTF-8. * Add max_row_size to dict_table_t. * btr0cur.c btr_copy_externally_stored_field(): Only set the 'offset' variable when needed. * buf0buf.c buf_page_io_complete(): Write to the error log if the page number or the space id o the disk do not match those in memory. Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB. The function is only being called #ifdef UNIV_IBUF_DEBUG. * innodb.result Adjust the results for changes in the foreign key error messages. * mem0mem.c|h New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat(). * os0file.c Check the page trailers also after writing to disk. This improves chances of diagnosing bug 18886. os_file_check_page_trailers(): New function for checking that the two copies of the LSN stamped on the page match. os_aio_simulated_handle(): Call os_file_check_page_trailers() before and after os_file_write(). * row0mysql.c Move trx_commit_for_mysql(trx) calls before calls to row_mysql_unlock_data_dictionary(trx) (bug 19727). * row0sel.c row_fetch_print(): Handle SQL NULL values without crashing. row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field when handling an externally stored column. Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined. This should allow the compiler to generate more compact code for assertions. * ut0list.c|h Add ib_list_create_heap().

Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Applied innodb-5.1-ss269 snapshot.

Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces.

Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock.

Added xml patch to mysqldump. Made innodb to compile more cleanly with debugging options enabled. Fixed a few bugs and found a few possible bugs, which I hope Heikki will check. Comments needs to be fixed too. Some while() functions should be changed to do ... until for documenting purposes, because some of them must and will be processed at least once, or a variable would be used uninitialized.

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

Applied innodb-5.1-ss594 snapshot. Fixed BUG#19542 "InnoDB doesn't increase the Handler_read_prev couter". Fixed BUG#19609 "Case sensitivity of innodb_data_file_path gives stupid error". Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers. New: innobase_convert_from_table_id(), innobase_convert_from_id(), innobase_convert_from_filename(), innobase_get_charset. dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(), dict_skip_word(), dict_create_foreign_constraints_low(): Add parameter 'cs' so that isspace() can be replaced with my_isspace(), whose operation depends on the connection character set. dict_scan_id(): Convert identifier to UTF-8. dict_str_starts_with_keyword(): New extern function, to replace dict_accept() in row_search_for_mysql(). mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier(). ha_innobase::create(): Remove the thd->convert_strin() call. Pass the statement to InnoDB in the connection character set and let InnoDB convert the identifier to UTF-8. * Add max_row_size to dict_table_t. * btr0cur.c btr_copy_externally_stored_field(): Only set the 'offset' variable when needed. * buf0buf.c buf_page_io_complete(): Write to the error log if the page number or the space id o the disk do not match those in memory. Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB. The function is only being called #ifdef UNIV_IBUF_DEBUG. * innodb.result Adjust the results for changes in the foreign key error messages. * mem0mem.c|h New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat(). * os0file.c Check the page trailers also after writing to disk. This improves chances of diagnosing bug 18886. os_file_check_page_trailers(): New function for checking that the two copies of the LSN stamped on the page match. os_aio_simulated_handle(): Call os_file_check_page_trailers() before and after os_file_write(). * row0mysql.c Move trx_commit_for_mysql(trx) calls before calls to row_mysql_unlock_data_dictionary(trx) (bug 19727). * row0sel.c row_fetch_print(): Handle SQL NULL values without crashing. row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field when handling an externally stored column. Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined. This should allow the compiler to generate more compact code for assertions. * ut0list.c|h Add ib_list_create_heap().

Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined. This should allow the compiler to generate more compact code for assertions. * ut0list.c|h Add ib_list_create_heap().

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock.

Applied innodb-5.1-ss594 snapshot. Fixed BUG#19542 "InnoDB doesn't increase the Handler_read_prev couter". Fixed BUG#19609 "Case sensitivity of innodb_data_file_path gives stupid error". Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers. New: innobase_convert_from_table_id(), innobase_convert_from_id(), innobase_convert_from_filename(), innobase_get_charset. dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(), dict_skip_word(), dict_create_foreign_constraints_low(): Add parameter 'cs' so that isspace() can be replaced with my_isspace(), whose operation depends on the connection character set. dict_scan_id(): Convert identifier to UTF-8. dict_str_starts_with_keyword(): New extern function, to replace dict_accept() in row_search_for_mysql(). mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier(). ha_innobase::create(): Remove the thd->convert_strin() call. Pass the statement to InnoDB in the connection character set and let InnoDB convert the identifier to UTF-8. * Add max_row_size to dict_table_t. * btr0cur.c btr_copy_externally_stored_field(): Only set the 'offset' variable when needed. * buf0buf.c buf_page_io_complete(): Write to the error log if the page number or the space id o the disk do not match those in memory. Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB. The function is only being called #ifdef UNIV_IBUF_DEBUG. * innodb.result Adjust the results for changes in the foreign key error messages. * mem0mem.c|h New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat(). * os0file.c Check the page trailers also after writing to disk. This improves chances of diagnosing bug 18886. os_file_check_page_trailers(): New function for checking that the two copies of the LSN stamped on the page match. os_aio_simulated_handle(): Call os_file_check_page_trailers() before and after os_file_write(). * row0mysql.c Move trx_commit_for_mysql(trx) calls before calls to row_mysql_unlock_data_dictionary(trx) (bug 19727). * row0sel.c row_fetch_print(): Handle SQL NULL values without crashing. row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field when handling an externally stored column. Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined. This should allow the compiler to generate more compact code for assertions. * ut0list.c|h Add ib_list_create_heap().

Applied innodb-5.1-ss269 snapshot. Fixed BUGS: #3300: "UPDATE statement with no index column in where condition locks all rows" Implement semi-consistent read to reduce lock conflicts at the cost of breaking serializability. ha_innobase::unlock_row(): reset the "did semi consistent read" flag ha_innobase::was_semi_consistent_read(), ha_innobase::try_semi_consistent_read(): new methods row_prebuilt_t, row_create_prebuilt(): add field row_read_type for keeping track of semi-consistent reads row_vers_build_for_semi_consistent_read(), row_sel_build_committed_vers_for_mysql(): new functions row_search_for_mysql(): implement semi-consistent reads #9802: "Foreign key checks disallow alter table". Added test cases. #12456: "Cursor shows incorrect data - DML does not affect, probably caching" This patch implements a high-granularity read view to be used with cursors. In this high-granularity consistent read view modifications done by the creating transaction after the cursor is created or future transactions are not visible. But those modifications that transaction did before the cursor was created are visible. #12701: "Support >4GB buffer pool and log files on 64-bit Windows" Do not call os_file_create_tmpfile() at runtime. Instead, create all tempfiles at startup and guard access to them with mutexes. #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. #14189: "VARBINARY and BINARY variables: trailing space ignored with InnoDB" innobase_init(): Assert that DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number. dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns. row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE when trying to change the length of a VARBINARY column that refers to or is referenced by a BINARY column. BINARY columns are no longer padded on comparison, and thus they cannot be padded on storage either. #14747: "Race condition can cause btr_search_drop_page_hash_index() to crash" 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. #15108: "mysqld crashes when innodb_log_file_size is set > 4G" #15308: "Problem of Order with Enum Column in Primary Key" #15550: "mysqld crashes in printing a FOREIGN KEY error in InnoDB" row_ins_foreign_report_add_err(): When printing the parent record, use the index in the parent table rather than the index in the child table. #15653: "Slow inserts to InnoDB if many thousands of .ibd files" Keep track on unflushed modifications to file spaces. When there are tens of thousands of file spaces, flushing all files in fil_flush_file_spaces() would be very slow. fil_flush_file_spaces(): Only flush unflushed file spaces. fil_space_t, fil_system_t: Add a list of unflushed spaces. #15991: "innodb-file-per-table + symlink database + rename = cr" os_file_handle_error(): Map the error codes EXDEV, ENOTDIR, and EISDIR to the new code OS_FILE_PATH_ERROR. Treat this code as OS_FILE_PATH_ERROR. This fixes the crash on RENAME TABLE when the .ibd file is a symbolic link to a different file system. #16157: "InnoDB crashes when main location settings are empty" This patch is from Heikki. #16298: "InnoDB segfaults in INSERTs in upgrade of 4.0 -> 5.0 tables with VARCHAR BINARY" dict_load_columns(): Set the charset-collation code DATA_MYSQL_BINARY_CHARSET_COLL for those binary string columns that lack a charset-collation code, i.e., the tables were created with an older version of MySQL/InnoDB than 4.1.2. #16229: "MySQL/InnoDB uses full explicit table locks in trigger processing" Take a InnoDB table lock only if user has explicitly requested a table lock. Added some additional comments to store_lock() and external_lock(). #16387: "InnoDB crash when dropping a foreign key <table>_ibfk_0" Do not mistake TABLENAME_ibfk_0 for auto-generated id. dict_table_get_highest_foreign_id(): Ignore foreign constraint identifiers starting with the pattern TABLENAME_ibfk_0. #16582: "InnoDB: Error in an adaptive hash index pointer to page" Account for a race condition when dropping the adaptive hash index for a B-tree page. btr_search_drop_page_hash_index(): Retry the operation if a hash index with different parameters was built meanwhile. Add diagnostics for the case that hash node pointers to the page remain. btr_search_info_update_hash(), btr_search_info_update_slow(): Document the parameter "info" as in/out. #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. dict_foreign_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 unititialised values" buf_block_init(): Reset magic_n, buf_fix_count and io_fix to avoid testing uninitialized variables.

node_ptr_fails:
Applied innodb-5.1-ss594 snapshot. Fixed BUG#19542 "InnoDB doesn't increase the Handler_read_prev couter". Fixed BUG#19609 "Case sensitivity of innodb_data_file_path gives stupid error". Fixed BUG#19727 "InnoDB crashed server and crashed tables are ot recoverable". Also: * Remove remnants of the obsolete concept of memoryfixing tables and indexes. * Remove unused dict_table_LRU_trim(). * Remove unused 'trx' parameter from dict_table_get_on_id_low(), dict_table_get(), dict_table_get_and_increment_handle_count(). * Add a normal linked list implementation. * Add a work queue implementation. * Add 'level' parameter to mutex_create() and rw_lock_create(). Remove mutex_set_level() and rw_lock_set_level(). * Rename SYNC_LEVEL_NONE to SYNC_LEVEL_VARYING. * Add support for bound ids in InnoDB's parser. * Define UNIV_BTR_DEBUG for enabling consistency checks of FIL_PAGE_NEXT and FIL_PAGE_PREV when accessing sibling pages of B-tree indexes. btr_validate_level(): Check the validity of the doubly linked list formed by FIL_PAGE_NEXT and FIL_PAGE_PREV. * Adapt InnoDB to the new tablename to filename encoding in MySQL 5.1. ut_print_name(), ut_print_name1(): Add parameter 'table_id' for distinguishing names of tables from other identifiers. New: innobase_convert_from_table_id(), innobase_convert_from_id(), innobase_convert_from_filename(), innobase_get_charset. dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(), dict_skip_word(), dict_create_foreign_constraints_low(): Add parameter 'cs' so that isspace() can be replaced with my_isspace(), whose operation depends on the connection character set. dict_scan_id(): Convert identifier to UTF-8. dict_str_starts_with_keyword(): New extern function, to replace dict_accept() in row_search_for_mysql(). mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier(). ha_innobase::create(): Remove the thd->convert_strin() call. Pass the statement to InnoDB in the connection character set and let InnoDB convert the identifier to UTF-8. * Add max_row_size to dict_table_t. * btr0cur.c btr_copy_externally_stored_field(): Only set the 'offset' variable when needed. * buf0buf.c buf_page_io_complete(): Write to the error log if the page number or the space id o the disk do not match those in memory. Also write to the error log if a page was read from the doublewrite buffer. The doublewrite buffer should be only read by the lower-level function fil_io() at database startup. * dict0dict.c dict_scan_table_name(): Remove fallback to differently encoded name when the table is not found. The encoding is handled at a higher level. * ha_innodb.cc Increment statistic counter in ha_innobase::index_prev() (bug 19542). Add innobase_convert_string wrapper function and a new file ha_prototypes.h. innobase_print_identifier(): Remove TODO comment before calling get_quote_char_for_identifier(). That function apparently assumes the identifier to be encoded in UTF-8. * ibuf0ibuf.c|h ibuf_count_get(), ibuf_counts[], ibuf_count_inited(): Define these only #ifdef UNIV_IBUF_DEBUG. Previously, when compiled without UNIV_IBUF_DEBUG, invoking ibuf_count_get() would crash InnoDB. The function is only being called #ifdef UNIV_IBUF_DEBUG. * innodb.result Adjust the results for changes in the foreign key error messages. * mem0mem.c|h New: mem_heap_dup(), mem_heap_printf(), mem_heap_cat(). * os0file.c Check the page trailers also after writing to disk. This improves chances of diagnosing bug 18886. os_file_check_page_trailers(): New function for checking that the two copies of the LSN stamped on the page match. os_aio_simulated_handle(): Call os_file_check_page_trailers() before and after os_file_write(). * row0mysql.c Move trx_commit_for_mysql(trx) calls before calls to row_mysql_unlock_data_dictionary(trx) (bug 19727). * row0sel.c row_fetch_print(): Handle SQL NULL values without crashing. row_sel_store_mysql_rec(): Remove useless call to rec_get_nth_field when handling an externally stored column. Fetch externally stored fields when using InnoDB's internal SQL parser. Optimize BLOB selects by using prebuilt->blob_heap directly instead of first reading BLOB data to a temporary heap and then copying it to prebuilt->blob_heap. * srv0srv.c srv_master_thread(): Remove unreachable code. * srv0start.c srv_parse_data_file_paths_and_sizes(): Accept lower-case 'm' and 'g' as abbreviations of megabyte and gigabyte (bug 19609). srv_parse_megabytes(): New fuction. * ut0dbg.c|h Implement InnoDB assertions (ut_a and ut_error) with abort() when the code is compiled with GCC 3 or later on other platforms than Windows or Netware. Also disable the variable ut_dbg_stop_threads and the function ut_dbg_stop_thread() i this case, unless UNIV_SYC_DEBUG is defined. This should allow the compiler to generate more compact code for assertions. * ut0list.c|h Add ib_list_create_heap().
