      branches/zip: page_zip_empty_size(): New function to compute the · 5a21753b

      guaranteed free space available for inserting one record.
      
      btr_page_get_sure_split_rec(), btr_cur_pessimistic_insert():
      Use page_zip_empty_size().
      
      btr_page_split_and_insert(): Relax a debug assertion that there should
      be at least two user records on the page.  On compressed pages, we may
      be able to write only one record.

      branches/zip: Instrument the buffer pool allocator and deallocator · ff0acd76
      marko authored
      for more accurate Valgrind debugging.
      
      univ.i: Introduce UNIV_DEBUG_VALGRIND, UNIV_MEM_VALID, and UNIV_MEM_INVALID.
      
      buf_LRU_block_free_non_file_page(): Invalidate the buffer frame
      with UNIV_MEM_INVALID().
      
      buf_LRU_get_free_block(): Declare the buffer frame valid
      with UNIV_MEM_VALID().
      
      Other memory is allocated and deallocated via malloc() and free(),
      which are already overridden by Valgrind.  Without the added
      instrumentation, accesses to free pages in the buffer pool cannot
      be caught.
      
      The diagnostics could probably be improved further by declaring all
      non-latched buffer frames invalid.

      branches/zip: Fix bugs #ifdef UNIV_DEBUG. · 3b03315f
      marko authored
      rec_convert_dtuple_to_rec_old(): Initialize the record in order to avoid
      bogus Valgrind warnings about the ut_ad() in mach_write_to_1() and
      mach_write_to_2().
      
      page_zip_compress(), page_zip_write_rec(), page_zip_write_blob_ptr():
      Replace ut_ad(page_validate(...)) with ut_ad(page_simple_validate_new(...)),
      because otherwise crash recovery would fail.

      Make page_zip->data point to an address different from page,
      to avoid calling memcpy() with overlapping source and destination.

      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.

      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.)

      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.)
