of externally stored columns to 108 bytes when possible. This will unmask a bug in the handling of BLOBs on compressed tablespaces, especially of small page sizes. Apparently, the locally stored part must be less than 235 bytes in size for the bug to occur. dict_col_struct: Add field min_prefix. dict_index_build_internal_non_clust(): Adjust min_prefix.

of non-clustered indexes. On these pages, only the bytes rec[-5..-1] will be omitted from the compressed data stream. Save time by not looking for trx_id or externally stored columns.

externally stored columns. Make some use of the fact in compression and decompression. rec_init_offsets(): Add ut_ad(dict_index_is_clust(index)) before flagging external columns. page_zip_get_trailer_len(): Assert ut_ad(!page_zip->n_blobs) unless dict_index_is_clust(index). page_zip_get_n_prev_extern(): Add ut_ad(dict_index_is_clust(index)). page_zip_compress(), page_zip_decompress_low(): Add dict_index_is_clust() assertions. Allow completely external storage of columns. Simplify the computation of "externs". page_zip_write_rec(): Store leaf node records of non-clustered indexes with one memcpy(), avoiding rec_offs_n_extern() and the for loop. page_zip_write_blob_ptr(): Add ut_ad(dict_index_is_clust(index)). Simplify the computation of "externs". page_zip_clear_rec(): Only attempt to zero out BLOB pointers when the record belongs to a leaf page of a clustered index. page_zip_dir_delete(): Take a fast path when the record is not on a leaf page of a clustered index. Simplify the computation of "externs". page_zip_copy(): Assert that n_blobs is zero on anything else than leaf pages of clustered indexes.

if and only if the records on the page contain a trx_id column. (Dummy indexes of non-leaf pages will always show up as non-clustered.)

of secondary indexes. (This is just an optimization; the logic in the search loop would never store such records externally.)

buf_LRU_get_free_block(): When zip_size changes, initialize all fields of page_zip. This avoids an assertion failure in page_create_zip() when a block with an originally larger zip_size is reallocated. fsp_get_space_header(): Assert that the stored space id matches. xdes_get_state(): Assert that the state is valid.
