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().
