mem_alloc2(): New macro. This is a variant of mem_alloc() that
returns the allocated size, which is equal to or greater than
the requested size.
mem_alloc_func(): Add the output parameter *size for the allocated size.
When it is set, adjust the parameter passed to mem_heap_alloc().
rec_copy_prefix_to_buf_old(), rec_copy_prefix_to_buf(): Use mem_alloc2()
instead of mem_alloc().
was actually obtained from the buddy allocator. This should avoid some
internal memory fragmentation in mem_heap_create() and mem_heap_alloc().
mem_area_alloc(): Change the in parameter size to an in/out parameter.
Adjust the size based on what was obtained from pool->free_list[].
mem_heap_create_block(): Adjust block->len to what was obtained from
mem_area_alloc().
rec_print_comp(): New function, sliced from rec_print_new().
rec_print_old(), rec_print_comp(): Print the untruncated length of the column.
row_merge_print_read, row_merge_print_write, row_merge_print_cmp:
New flags, to enable debug printout in UNIV_DEBUG builds.
row_merge_tuple_print(): New function for UNIV_DEBUG builds.
row_merge_read_rec(): Obey row_merge_print_read.
row_merge_buf_write(), row_merge_write_rec_low(),
row_merge_write_eof(): Obey row_merge_print_write.
row_merge_cmp(): Obey row_merge_print_cmp.

for design notes.
Things that need to be resolved before this goes live:
* MySQL must add thd_get_thread_id() function to their code
http://bugs.mysql.com/30930
* Allocate memory from mem_heap instead of using mem_alloc()
* Copy table name and index name into the cache because they may be
freed later which will result in referencing freed memory

UNIV_MEM_ASSERT_RW(): New macro, to check that the contents of a memory
area is defined.
UNIV_MEM_ASSERT_W(): New macro, to check that a memory area is writable.
UNIV_MEM_ASSERT_AND_FREE(): New macro, to check that the memory is
writable before declaring it free (unwritable). This replaces UNIV_MEM_FREE()
in many places.
mem_init_buf(): Declare the memory undefined.
mem_erase_buf(): Declare the memory freed.
trx_t: Remove dict_undo_list and dict_redo_list.
innobase_create_temporary_tablename(): Replace TEMP_TABLE_PREFIX with
a table name suffix "#1" or "#2". In this way, the user can restore
precious data, should anything go wrong. It is possible to reach an
inconsistent state, because the creation, deletion and renaming of
single-table tablespaces are not transactional.
ut_print_namel(), fil_make_ibd_name(), innobase_rename_table(): Remove
the special treatment of TEMP_TABLE_PREFIX.
Introduce TEMP_INDEX_PREFIX == 0xff for temporary indexes. This byte
cannot occur in index names since MySQL 4.1. However, it might have
been possible to use this byte in MySQL 4.0.
recv_recovery_from_checkpoint_finish(): Call the new function
row_merge_drop_temp_indexes(), to drop all indexes whose name starts
with the byte 0xff.
row_merge_rename_indexes(): Renamed from row_merge_rename_index().
Remove the parameter "index".
row_drop_table_for_mysql(): Unconditionally call trx_commit_for_mysql().
row_drop_table_for_mysql_no_commit(): Correct the function commit,
based on the corrected comment of row_drop_table_for_mysql(). Rely on
table->to_be_dropped instead of TEMP_TABLE_PREFIX.
ha_innobase::add_index(): Simplify the control flow.
is inline and accesses lock_t members.
As advised by Marko rename lock_get_type() to lock_get_type_low() and
create a public non-inline function lock_get_type() which calls
lock_get_type_low().
Approved by: Marko
Move lock_rec_find_set_bit() from lock0priv.h to lock0lock.h. This
function is needed in the INFORMATION_SCHEMA implementation which
currently resides in trx/
Approved by: Marko
#ifdef ROW_MERGE_IS_INDEX_USABLE, to avoid growing the memory
footprint until MySQL implements and calls the virtual method
handler::is_index_available() or something equivalent.
in fast index creation. The prefix was previously TEMP_TABLE_PREFIX == '/',
which may occur in index names.
ut_print_namel(): Do not assume that all '/' are separators between
database and table names.
only after the buffer_cache has warmed up. During the initial warmup
phase these values are set to zero. We should recommend to move the
block to the start of the LRU in this case.
Also added some comments to buf0buf.c about the LRU logic.
reviewed by: Sunny
ha_innobase::add_index(): Add assertions about !trx->sync_cb and
!trx->dict_redo_list. Remove a bogus comment. Replace
row_lock_table_for_merge() with row_merge_lock_table().
row_merge_lock_table(): Renamed from row_lock_table_for_merge()
and moved from row0mysql.c to row0merge.c. Always lock the table in
the mode LOCK_X. Call que_graph_free() in order not to leak memory.
freed with UNIV_MEM_FREE(). Before this change, the memory
freed by mem_heap_empty() was not completely flagged free
in UNIV_DEBUG_VALGRIND builds. After this change, Valgrind
will hopefully catch all errors caught by UNIV_MEM_DEBUG.
innodb-index.test: Add some test cases for FOREIGN KEY constraints.
row_merge_rename_tables(): New function,
adapted from row_rename_table_for_mysql().
ha_innobase::add_index(): Use row_merge_rename_tables().
mem_heap_zalloc() and mem_zalloc(), because calloc() in the C runtime
library takes two size parameters, not one.
mem_heap_zalloc(): Add debug assertions. Document that the return value
is never NULL.
Remove the unused constant DICT_NOT_READY.
Make dict_index_t::type a bit-field, and move it next to other bit-fields.
Add a const qualifier to dict_index_t::name.
It was only set by ha_innobase::prepare_drop_index(), which can return
the appropriate MySQL error code (HA_ERR_DROP_INDEX_FK) directly.
ha_innobase::add_index(): Correct the function comment.
ha_innobase::prepare_drop_index(): Correct the function comment.
Return MySQL error codes directly.
ha_innobase::final_drop_index(): Correct the function comment.
trx_t: Change the type of error_info from void* to const dict_index_t*.
trx_get_error_info(): Add const qualifier to trx_t*. Make this an
inline function.
innobase_create_key_def(), row_table_got_default_clust_index(),
row_get_mysql_key_number_for_index(): Add a const qualifier.
dict_table_get_first_index(), dict_table_get_next_index(): Define
as a const-preserving macro. Preserve the old function for UNIV_DEBUG,
but add a const qualifier to the parameter and cast away the constness.
row_merge_create_temporary_table(): Add the parameter index_defs.
DB_PRIMARY_KEY_IS_NULL: New error code, mapped to ER_PRIMARY_CANT_HAVE_NULL.
row_merge_read_clustered_index(): Replace the parameter "table" with the
two parameters "old_table" and "new_table". Detect NULL values of columns
that are supposed to be NOT NULL.
row_merge_col_prtype(): New auxiliary function, used by
row_merge_create_temporary_table() to flag NOT NULL any columns
contained in an added PRIMARY KEY.
innobase_copy_index_field_def(): Remove parameter heap. The field->name
will not be deallocated before the copied index has been added to the
data dictionary cache.
innobase_copy_index_def(): Add const qualifier to dict_index_t*.
Add an assertion !dict_index_is_clust(index).
ha_innobase::add_index(): Add the missing user_thd parameter to the
convert_error_code_to_mysql() call that was forgotten from r1686.
merge_index_field_struct: Add const qualifier to field_name.
merge_index_def_struct: Add const qualifier to name.
row_merge_build_indexes(): Improve the function comment.
row_merge_drop_table(): Remove bogus assertion ut_a(table->to_be_dropped).
row_mysql_read_true_varchar(), row_mysql_read_blob_ref(),
row_mysql_store_col_in_innobase_format(),
row_sel_convert_mysql_key_to_innobase(): Add const qualifiers.
row_sel_convert_mysql_key_to_innobase(): Document that the first parameter
is in/out.
