succeed.
row_merge_drop_index(): Remove bogus comment about void return value.
trx_dummy_sess: Move the declaration from trx0roll.h to trx0trx.h,
because the variable is defined in trx0trx.c.
Some things still fail in innodb-index.test, and there seems to be
a race condition (data dictionary lock wait) when running with --valgrind.

dfield_print_also_hex(), dfield_print(): Replace if...else if with switch.
Observe dfield_is_ext().
to rec_t*. Remove the ut_ad(rec_offs_validate()), because this function
will be called from row0merge.c on a record that lacks the
REC_N_NEW_EXTRA_BYTES.
now that all of InnoDB code is built from a single Makefile and it should
not be possible to build the modules with mutually incompatible options.
#define INSIDE_HA_INNOBASE_CC: Remove.
srv_sizeof_trx_t_in_ha_innodb_cc: Remove.
dict_table_get_low_noninlined(): Remove. This function was unused.
Remove all _noninline functions. Remove the _noninline suffix from

row_rec_to_index_entry_low(): New function.
row0merge.c: Implement merge sort based on file streams instead of
fixed-size blocks. Sort the small blocks as arrays of dfield_t*,
because it is faster than invoking rec_get_offsets() for every
comparison.
row_merge_mark_prebuilt_obsolete(): Rename to row_prebuilt_table_obsolete()
and move from row0merge.c to row0mysql.c. Remove the parameter trx.
row_merge_print_table(): Remove.
row_remove_indexes_for_mysql(): Rename to row_merge_drop_indexes(),
move from row0mysql.c to row0merge.c and make the return type void.
row_merge_remove_index(): Rename to row_merge_drop_index() and make
the return type void.
of UT_SORT_FUNCTION_BODY is best done by defining SORT_FUN and CMP_FUN as
macros when needed. The solution of r1523 allows for only one extra parameter.
rec_get_converted_size_new(): Rename to rec_get_converted_size_comp().
Add const qualifier to dtuple. Remove the assertion
dict_table_is_comp(index->table), because this function will be invoked
when populating the temporary files in fast index creation.

Add parameter "extra".
rec_init_offsets_comp_ordinary(): New function. Used in rec_init_offsets().
exactly. Rename the local variable "ulint level" to "ibool leaf".
Document that if the function returns DB_SUCCESS on a compressed page that
is covered by the insert buffer, the mini-transaction must be committed
before latching any further pages. Verify that this is the case on all
execution paths.
the insert buffer bitmap.
ibuf_set_free_bits_func(): Never disable redo logging.
ibuf_update_free_bits_zip(): Remove.

to reset the insert buffer free bits.
btr_cur_update_in_place(), btr_cur_optimistic_update(),
btr_cur_pessimistic_update(): Update the free bits in the same
mini-transaction. Document that the mini-transaction must be
committed before latching any further pages. Verify that this
is the case in all execution paths.
row_ins_sec_index_entry_by_modify(), row_ins_clust_index_entry_by_modify(),
row_undo_mod_clust_low(): Because these functions call
btr_cur_update_in_place(), btr_cur_optimistic_update(), or
btr_cur_pessimistic_update(), document that the mini-transaction must be
committed before latching any further pages. Verify that this is the case
in all execution paths.
page_cur_tuple_insert(), page_cur_rec_insert(): Improve the documentation.
Note that the physical position of page_cursor may change.
page_cur_rec_insert(), page_cur_insert_rec_low(), page_cur_insert_rec_zip():
Add a const qualifier to the parameter rec.
crash recovery is in progress. This avoids a hang when
btr_parse_page_reorganize(), called from an I/O handler thread,
attempts to acquire log_sys->mutex while it is being held by
the main thread (the one that runs innobase_init()). This change
was committed accidentally. It may be unsafe to clear
mtr.modifications, because buf_page_release() at mtr_commit() may
forget to put modified pages to the flush list.
Cleanup: Remove the "type" parameter from many ibuf functions.
Let the caller check that !dict_index_is_clust(). This should avoid
function calls and register spilling.
ibuf_set_free_bits_func(), ibuf_set_free_bits(): Remove the parameter "type".
ibuf_reset_free_bits_with_type(): Rename to ibuf_reset_free_bits().
Remove the parameter "type".
ibuf_update_free_bits_if_full(), ibuf_update_free_bits_zip(),

Replace byte offsets of type dulint with block offsets of type ulint.
Avoid references to MERGE_BLOCK_SIZE.
Improve the language of some comments.

status of os_file_read() and os_file_write(). TO DO: check the status
in the callers.
innobase_create_temporary_tablename(): Add static qualifier. Allocate
the memory from heap. Return a fixed identifier.
ha_innobase::add_index(): Allocate all memory from a single heap.
Simplify error handling. Use a fixed prefix for temporary table names,

row_build_index_for_mysql(): Remove the parameter new_primary.
Move more definitions from row0mysql.h to row0mysql.c. Remove the
unused definition of merge_thread.

new tablespace identifier of a single-table tablespace that has been
recreated. When SYS_INDEXES.PAGE_NO == FIL_NULL, do not abort but
create the index tree.
fil_discard_tablespace(): Pass the return code from fil_delete_tablespace().
row_truncate_table_for_mysql(): Attempt to discard and recreate
single-table tablespaces. Reassign the tablespace identifier both in
the data dictionary (SYS_TABLES and SYS_INDEXES) and in the data
dictionary cache.
Previously, when big_rec was returned, the fields would point to
freed memory. The memory heap was allocated locally, and the data tuple
was allocated from the heap, and the big_rec would point to some fields
in the data tuple.
row_ins_clust_index_entry_by_modify(): Add parameter heap,
for the same reason.
functions.
ut_malloc_low(): Flag the block with UNIV_MEM_ALLOC(). Do not flag the
block with UNIV_MEM_FREE() in ut_free(), because it would cause bogus
Valgrind warnings in the underlying memory allocator.
