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.
the insert buffer bitmap.
ibuf_set_free_bits_func(): Never disable redo logging.
ibuf_update_free_bits_zip(): Remove.
btr_page_reorganize_low(), page_zip_reorganize(): Do not update the insert
buffer bitmap. Instead, document that callers will have to take care of it,
and adapt the callers.
btr_compress(): On error, reset the insert buffer free bits.
btr_cur_insert_if_possible(): Do not modify the insert buffer bitmap.
btr_compress(), btr_cur_optimistic_insert(): On compressed pages,
reset the insert buffer bitmap. Document why.
btr_cur_update_alloc_zip(): Document why it is necessary and sufficient
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.
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.
in the clustered index to be smaller than the indexed prefix in secondary
indexes.
row_ext_lookup(): Return NULL if the column is not stored externally.
trx_undo_rec_get_partial_row(): row_build(): Add parameter row_ext_t** ext.
row_build_index_entry(): Add the parameter row_ext_t* ext.
Invoke row_ext_lookup() to fetch prefixes of externally stored columns.
upd_node_t, undo_node_t, purge_node_t: Add the field row_ext_t* ext.
BLOB pointers, trx_id, and roll_ptr.
btr_empty(), btr_create(), page_create(): Add parameter "index", as some
index information will be encoded on the compressed page.
Define REC_NODE_PTR_SIZE as 4.
Allow btr_page_reorganize() and btr_page_reorganize_low() to fail.
Define the error code DB_ZIP_OVERFLOW.
Make row_ins_index_entry_low() static.
page0zip: Encode the index, log reorganized records, and store uncompressed
fields separately from the compressed data stream.
