      branches/zip: Speed up the compression and decompression of leaf pages · 1180ce98
      marko authored
      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.

      branches/zip: Assert that only leaf pages of clustered indexes may contain · fb8ce599
      marko authored
      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.

      branches/zip: page_zip_fields_decode(): Set index->type to DICT_CLUSTERED · 2f08aceb
      marko authored
      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.)

      branches/zip: page_zip_decompress(): Initialize page_zip->n_blobs before · 3a27b5c8
      marko authored
      referencing it, to prevent a ut_ad() assertion on page_zip_get_trailer_len()
      from failing.  Promote that assertion to ut_a().

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

      branches/zip: Clean up debug code. · 41468be9
      marko authored
      struct mtr_struct: Omit unused field "state" unless #ifdef UNIV_DEBUG.
      
      buf_block_buf_fix_inc_debug(): Remove redundant __attribute__((unused))
      and #ifdef UNIV_SYNC_DEBUG.

      branches/zip: page_zip_decompress_low(): Clear the node_ptr during · 7255b3fd
      marko authored
      initial decompression, in case the record will be deleted and the
      space will be reused by a smaller record.
      
      page_zip_clear_rec_disable: Note the possibility of a page_zip_validate()
      failure when the space of a deleted record is reused by a smaller record.

      branches/zip: Improve diagnostics. · e148206a
      marko authored
      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.
