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.

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.
