463aaf28ba branches/zip: Avoid memory fragmentation when adding column definitions
to tables.

dict_mem_table_add_col(): Add the parameter "heap" for temporary memory
allocation.  Allow it and "name" to be NULL.  These parameters are NULL
when creating dummy indexes.

dict_add_col_name(): Remove calls to ut_malloc() and ut_free().

dict_table_get_col_name(): Allow table->col_names to be NULL.

dict_table_add_system_columns(), dict_table_add_to_cache():
Add the parameter "heap".

d266262af6 branches/zip: Prepare for buffer pool allocation in several chunks.
buf_pool_t: Remove n_frames, max_size, and blocks_of_frames.
The current buffer pool size is in curr_size.

buf_pool_init(): Remove parameter max_size.

buf_pool_get_max_size(), buf_pool_is_block(): Remove.

buf_block_align(): Do not assume that the buffer pool is allocated
in one chunk.  Replace dependency on buf_pool->blocks_of_frames
with a call to buf_page_hash_get().

dict_index_get_nth_col_pos(), dict_index_get_sys_col_pos(),

fbe4fe6022 branches/zip: Remove the casts introduced in r920 and r925. Replace the
accessors returning pointers with macros that preserve const qualifiers.
In UNIV_DEBUG builds, retain the accessors and cast away constness there.

dfield_get_type(), dfield_get_data(), dtuple_get_nth_field(),
dict_table_get_nth_col(), dict_table_get_sys_col(): Implement as macro
unless #ifdef UNIV_DEBUG.

rec_get_nth_field(): Replace with rec_get_nth_field_offs() that does not
do pointer arithmetics.  Implement rec_get_nth_field() as a macro.

8f07794024 branches/zip: Introduce const qualifiers to many read-only parameters
and modify some functions to return const pointers.  Add const qualifiers
to local variable declarations or casts to remove the const qualifier
in those places where write access is needed.

TODO: only store BTR_EXTERN_FIELD_REF_SIZE (20) bytes with the record,
and store the entire column externally.  (Bug #22496)

dict_col_t::min_prefix: Remove.

c3e2a8d45f branches/zip: dtuple_convert_big_rec(): Shorten the locally stored part
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.

1dd4d56863 branches/zip: Write compressed pages to disk.
os_aio_simulated_handle(): Temporarily disable os_file_check_page_trailers(),
which cannot be invoked on compressed pages.

dict_table_add_system_columns(): New function, split from
dict_table_add_to_cache().

mlog_parse_index(): Add system columns to the dummy table and identify
DB_TRX_ID and DB_ROLL_PTR in the dummy index.

buf_LRU_get_free_block(): Note that page_zip->data should be allocated from
an aligned memory pool.

buf_flush_buffered_writes(): Write compressed pages to disk.

buf_flush_post_to_doublewrite_buf(): Copy compressed pages to the
doublewrite buffer.  Zero fill any excess space.

buf_flush_init_for_writing(): Treat all compressed pages the same.

buf_read_page_low(): Read compressed pages from disk.

buf_page_io_complete(): Process compressed pages.

trx_sys_doublewrite_init_or_restore_page(): Process compressed pages.

mlog_write_initial_log_record_fast(): Enable a debug printout
#ifdef UNIV_LOG_DEBUG.

fsp_header_init(), fsp_fill_free_list(): Pass the compressed page size
to buf_page_create().

page_zip_compress_write_log(): Flatten the if-else if-else logic.

page_zip_parse_write_blob_ptr(): Do not test page_zip if page==NULL.

page_zip_parse_write_node_ptr(): Do not test page_zip if page==NULL.
Invoke mlog_close() correctly.

row_sel_store_row_id_to_prebuilt(): Add UNIV_UNLIKELY hint to an
assertion-like test.

e8e9fb28b4 branches/zip: Note that TRX_ID and ROLL_PTR only exist on B-tree leaf pages
of clustered indexes.  Previously, parts of the code assumed that these
columns would exist on all leaf pages.  Simplify the update-in-place of
these columns.

Add inline function dict_index_is_clust() to replace all tests
index->type & DICT_CLUSTERED.

Remove the redo log entry types MLOG_ZIP_WRITE_TRX_ID and
MLOG_ZIP_WRITE_ROLL_PTR, because the modifications to these columns
are covered by logical logging.

Fuse page_zip_write_trx_id() and page_zip_write_roll_ptr() into
page_zip_write_trx_id_and_roll_ptr().

page_zip_dir_add_slot(), page_zip_available(): Add flag "is_clustered",
so that no space will be reserved for TRX_ID and ROLL_PTR on leaf pages
of secondary indexes.

page_zip_apply_log(): Flag an error when val==0 is encoded with two bytes.

page_zip_write_rec(): Add debug assertions that there is enough space
available for the entry before copying the data bytes of the record.
