bddb5a0cca branches/zip: Add a UNIV_INTERN qualifier to every global function declaration
in *.h files, so that the function signatures in the *.h and *.c files fully
match each other.

ut_dulint_sort(): Add a UNIV_INTERN qualifier also to the function definition.

71a4f691b2 branches/zip: Fast index creation: Remove the ROW_PREBUILT_OBSOLETE nonsense.
Active transactions must not switch table or index definitions on the fly,
for several reasons, including the following:

 * copied indexes do not carry any history or locking information;
   that is, rollbacks, read views, and record locking would be broken

 * huge potential for race conditions, inconsistent reads and writes,
   loss of data, and corruption

Instead of trying to track down if the table was changed during a transaction,
acquire appropriate locks that protect the creation and dropping of indexes.

innodb-index.test: Test the locking of CREATE INDEX and DROP INDEX.  Test
that consistent reads work across dropped indexes.

lock_rec_insert_check_and_lock(): Relax the lock_table_has() assertion.
When inserting a record into an index, the table must be at least IX-locked.
However, when an index is being created, an IS-lock on the table is
sufficient.

row_merge_lock_table(): Add the parameter enum lock_mode mode, which must
be LOCK_X or LOCK_S.

row_merge_drop_table(): Assert that n_mysql_handles_opened == 0.
Unconditionally drop the table.

ha_innobase::add_index(): Acquire an X or S lock on the table, as appropriate.
After acquiring an X lock, assert that n_mysql_handles_opened == 1.
Remove the comments about dropping tables in the background.

ha_innobase::final_drop_index(): Acquire an X lock on the table.

dict_table_t: Remove version_number, to_be_dropped, and prebuilts.
ins_node_t: Remove table_version_number.

enum lock_mode: Move the definition from lock0lock.h to lock0types.h.

ROW_PREBUILT_OBSOLETE, row_update_prebuilt(), row_prebuilt_table_obsolete():
Remove.

row_prebuilt_t: Remove the declaration from row0types.h.

row_drop_table_for_mysql_no_commit(): Always print a warning if a table
was added to the background drop queue.

a2943ec761 branches/zip: Enclose the definition of dict_index_t::trx_id in
#ifdef ROW_MERGE_IS_INDEX_USABLE, to avoid growing the memory
footprint until MySQL implements and calls the virtual method
handler::is_index_available() or something equivalent.

064e5aae3f branches/zip: dict0mem.h: Minor cleanup.
Remove the unused constant DICT_NOT_READY.
Make dict_index_t::type a bit-field, and move it next to other bit-fields.
Add a const qualifier to dict_index_t::name.

fc65b08f53 branches/zip: Merge branches/fast-index-creation -r1413.
Fix some bugs.  The tests innodb and innodb-index fail, but that might
be due to an old MySQL source tree being used.

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".

732d2f3219 branches/zip: dtuple_convert_big_rec(): Reduce the locally stored part
of externally stored columns to REC_1BYTE_OFFS_LIMIT (128) bytes.
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.

c4e548cec0 branches/zip: Add row_ext_t for caching prefixes of externally stored columns.
This will be needed for fixing Bug #22496.

REC_MAX_INDEX_COL_LEN: New constant, copied from DICT_MAX_INDEX_COL_LEN.

row_ext_create(), row_ext_lookup(), row_ext_lookup_low(): New functions.

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.

6dd1d8c4fe branches/zip: Write the compressed page size to SYS_TABLES.TYPE
and to the file space header (FSP_PAGE_ZIP_SIZE, renamed from
FSP_LOWEST_NO_WRITE).

fil_space_struct: Add zip_size.

dict_table_struct: Embed zip_size in flags.

dict_table_zip_size(): Infer zip_size from table->flags.

dict_sys_tables_get_zip_size(): Read zip_size from SYS_TABLES.TYPE.

fil_space_get_zip_size(): Read zip_size from the file space header.

Add the redo log entry type MLOG_ZIP_FILE_CREATE.
