Add const qualifier to dict_index_t*.
row_rec_to_index_entry(): Add the parameters "offsets" and "n_ext".
btr_cur_optimistic_update(): Add an assertion that there are no externally
stored columns. Remove the unreachable call to btr_cur_unmark_extern_fields()
and the preceding unnecessary call to rec_get_offsets().
btr_push_update_extern_fields(): Remove the parameters index, offsets.
Only report the additional externally stored columns of the update vector.
row_build(), trx_undo_rec_get_partial_row(): Flag externally stored columns
also with dfield_set_ext().
rec_copy_prefix_to_dtuple(): Assert that there are no externally stored
columns in the prefix.
row_build_row_ref(): Note and assert that the index is a secondary index,
and assert that there are no externally stored columns.
row_build_row_ref_fast(): Assert that there are no externally stored columns.
rec_offs_get_n_alloc(): Expose the function.
row_build_row_ref_in_tuple(): Assert that there are no externally stored
columns in a record of a secondary index.
row_build_row_ref_from_row(): Assert that there are no externally stored
columns.
row_upd_check_references_constraints(): Add the parameter offsets, to
avoid a redundant call to rec_get_offsets().
row_upd_del_mark_clust_rec(): Add the parameter offsets. Remove
duplicated code.
row_ins_index_entry_set_vals(): Copy the external storage flag.
sel_pop_prefetched_row(): Assert that there are no externally stored
columns.

Since r1905, innobase_rec_to_mysql() does not require a clustered index record.
row_merge_dup_t: Remove old_table.
row_merge_dup_report(): Do not fetch the clustered index record. Simply
convert the tuple by innobase_rec_to_mysql().
row_merge_blocks(), row_merge(), row_merge_sort(): Add a TABLE* parameter
for reporting duplicate key values during file sort.
row_merge_read_clustered_index(): Replace UNIV_PAGE_SIZE with the more
appropriate sizeof(mrec_buf_t).
innobase_rec_to_mysql(): New function, for converting an InnoDB clustered
index record to MySQL table->record[0]. TODO: convert integer fields.
Currently, integer fields are in big-endian byte order instead of
host byte order, and signed integer fields are offset by 0x80000000.
innobase_rec_reset(): New function, for resetting table->record[0].
row_merge_build_indexes(): Add the parameter TABLE* table (the MySQL table
handle) for reporting duplicate key values.
dtuple_from_fields(): New function, to convert an array of dfield_t* to
dtuple_t.
dtuple_get_n_ext(): New function, to compute the number of externally stored
fields.
row_merge_dup_t: Structure for counting and reporting duplicate records.
row_merge_dup_report(): Function for counting and reporting duplicate records.
row_merge_tuple_cmp(), row_merge_tuple_sort(): Replace the ulint* n_dup
parameter with row_merge_dup_t* dup.
row_merge_buf_sort(): Add the parameter row_merge_dup_t* dup, which is
NULL when sorting a non-unique index.
row_merge_buf_write(), row_merge_heap_create(), row_merge_read_rec(),
row_merge_cmp(), row_merge_read_clustered_index(), row_merge_blocks(),
row_merge(), row_merge_sort(): Add const qualifiers.
row_merge_read_clustered_index(): Use a common error handling branch err_exit.
Invoke row_merge_buf_sort() differently on unique indexes.
row_merge_blocks(): note TODO: We could invoke innobase_rec_to_mysql()
to report duplicate key values when creating a clustered index.
row_merge(): Add the assertion ut_ad(half > 0).
row_merge_sort(): Compute the half of the merge file correctly. The
previous implementation used truncating division, which may result in
loss of records when the file size in blocks is not a power of 2.
Some bug still remains, because innodb-index.test will lose some
records from the clustered index after add primary key (a,b(255),c(255))
when row_merge_block_t is reduced to 8192 bytes.
row_merge(): Add the parameter "half". Add some Valgrind instrumentation.
Note that either stream can end before the other one.
row_merge_sort(): Calculate "half" for row_merge().
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.
in fast index creation.
row_merge_write_eof(), row_merge_buf_write(): When UNIV_DEBUG_VALGRIND
is defined, fill the rest of the block (after the end-of-block marker)
with 0xff.
row_merge_read_rec(): Correct a typo in a comment. Fix error in
arithmetics when the record spans two blocks.
row_merge_write_rec_low(): Add a "size" parameter. Add debug assertions
about extra_size and size.
row_merge_write_rec(): After writing a record, properly advance the
buffer pointer.
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.
row_drop_table_for_mysql() call with a call to
row_drop_table_for_mysql_no_commit(). The last parameter of
the function is ibool drop_db, not ibool do_commit. Also,
since r1790 of trunk it is not necessary to copy table->name.
#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.
created in fast index creation.
dict_load_indexes(): Always complain if the first index is not clustered.
lock_table_enqueue_waiting(): Always complain about lock waits in
a dictionary operation.
row_merge_rename_tables(): Add an assertion that dict_sys->mutex is
being held.
row_undo_mod_del_unmark_sec_and_undo_update(): Make the test about
temporary indexes more readable.
row_create_table_for_mysql(): Do not retry creating a temporary table
in fast index creation. Orphaned temporary tables will have to be dropped
in crash recovery.
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.
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.
row_merge_buf_add(): Add a prefetch instruction to row->fields.
Eliminate a variable from the copying loop, and move the termination
condition to the end of the loop.
row_merge_build_indexes(): Remove the second call to
trx_start_if_not_started().
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_merge_buf_create_low(): Swap the parameters max_tuples and buf_size,
because the callers had them swapped. Add debug assertions about
these parameters.
row_merge_buf_empty(): Return the emptied buffer. In some cases, the
buffer may be relocated.
be set always.
trx_rollback_active(): Split from trx_rollback_or_clean_all_without_sess().
row_undo_dictionary(): Do not return a value. Assert that all operations
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_t: Add an "external storage" flag, dfield->ext.
dfield_is_null(), dfield_is_ext(), dfield_set_ext(), dfield_set_null():
New functions.
dfield_copy(), dfield_copy_data(): Add const qualifiers, fix in/out comments.
data_write_sql_null(): Use memset().
big_rec_field_t: Replace byte* data with const void* data.
ut_ulint_sort(): Remove.
upd_field_t: Remove extern_storage.
upd_node_t: Replace ext_vec, n_ext_vec with n_ext.
row_merge_copy_blobs(): New function.
row_ins_index_entry(): Add the parameter "ibool foreign" for suppressing
foreign key checks during fast index creation or when inserting into
secondary indexes.
btr_page_insert_fits(): Add const qualifiers.
btr_cur_add_ext(), upd_ext_vec_contains(): Remove.
dfield_print_also_hex(), dfield_print(): Replace if...else if with switch.
Observe dfield_is_ext().
Because row_drop_table_for_mysql_no_commit() checks with dict_load_table()
if the table was successfully dropped, we cannot pass table->name to it.
row_merge_drop_table(): Pass a copy of table->name to
row_drop_table_for_mysql().
row_prebuilt_free(): Do not dereference prebuilt->table->name after a
successful invocation of row_add_table_to_background_drop_list(). The
table object may be freed at any time. Remove the debug message
"Dropping table".
occur in mysql-test-run, but mysql-test-run reports some warnings for
some tests and incorrect results for innodb-index.test.
innobase_start_trx_and_assign_read_view(): Use thd instead of current_thd.
ha_innobase::add_index(): Use ha_thd() instead of current_thd.
Commit the transaction at the end.
row_merge_rename_index(): Really change the name of the index. This was
broken in r1430.
row_merge_buf_add(): Correctly calculate buf->total_size.
row_merge_buf_write(): Add an assertion about buf->total_size.
row_merge_heap_create(), row_merge_read_rec(), row_merge_insert_index_tuples():
offsets needs to be 1 + REC_OFFS_HEADER_SIZE + n_fields. Previously, we
allocated one element too little.
row_merge_blocks(): Use goto instead of break in the AT_END argument
of ROW_MERGE_WRITE_GET_NEXT.
single os_mem_alloc_large() call. The function mem_alloc() that was
used previously allocates unaligned memory.
row_merge_blocks(): Replace block1, block2, block3 with a single array.
Replace buf1, buf2, buf3 with buf[3]. Replace b1..b3 with b0..b2.
Replace mrec1,2 with mrec0,1. Replace offsets1,2 with offsets0,1.
row_merge(), row_merge_sort(): Replace block1, block2, block3 with a
single array.
The creation of the primary key does not work. We will have to flag
externally stored columns and copy the externally stored part from
the old table.
row_build_index_for_mysql(): Rename to row_merge_build_indexes().
Move from row0mysql.c to row0merge.c.
Remove private declarations from row0merge.h. Make many functions static
in row0merge.c.
cmp_rec_rec_simple(): A new comparison function.
dict_index_get_min_size(): New function.
OS_FILE_FROM_FD(fd): A macro for converting from int to os_file_t.
rec_convert_dtuple_to_rec_comp(): Make the interface lower-level.
rec_get_converted_size_comp(): Return also extra_size.
UT_SORT_FUNCTION_BODY(): Remove reference to an obsolete test program.
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.
