The followin mysql-tests failed (and they are known to fail):

symbols. Use it for all definitions of non-static variables and functions.
lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is
referenced from pars0grm.c.
Actually, according to
nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:
* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs
The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.
The class ha_innodb is renamed from class ha_innobase by a #define. Thus,
there will be no clash with the builtin InnoDB. However, there will be some
overhead for invoking virtual methods of class ha_innodb. Ideas for making
the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
inserted, uncommitted clustered index records when determining if a
secondary index record that contains a column prefix of an externally
stored column is referencing the clustered index record.
field_ref_zero[]: A BLOB pointer full of zero, for use in comparisons.
btr_copy_externally_stored_field_prefix(): Assert that the BLOB pointer is set.
row_ext_lookup_ith(), row_ext_lookup(), row_ext_lookup_low(): Document
that field_ref_zero is returned when the BLOB cannot be fetched.
row_ext_lookup_low(): Return field_ref_zero and *len = 0 when the
BLOB pointer is unset.
row_build_index_entry(): Return NULL when a needed BLOB pointer cannot
be dereferenced (row_ext_lookup returns field_ref_zero). Check the
return value for NULL in callers.
row_vers_impl_x_locked_off_kernel(): Avoid comparisons when
row_build_index_entry() returns NULL.
row_vers_old_has_index_entry(): Ignore records for which
row_build_index_entry() returns NULL. The entry should never be NULL
in rollback, but it may be NULL in purge.
row_merge_buf_add(): Assert that row_ext_lookup() does not return
field_ref_zero. The table will be locked during index creation.
trx_t: Remove dict_undo_list and dict_redo_list.
innobase_create_temporary_tablename(): Replace TEMP_TABLE_PREFIX with
a table name suffix "#1" or "#2". In this way, the user can restore
precious data, should anything go wrong. It is possible to reach an
inconsistent state, because the creation, deletion and renaming of
single-table tablespaces are not transactional.
ut_print_namel(), fil_make_ibd_name(), innobase_rename_table(): Remove
the special treatment of TEMP_TABLE_PREFIX.
Introduce TEMP_INDEX_PREFIX == 0xff for temporary indexes. This byte
cannot occur in index names since MySQL 4.1. However, it might have
been possible to use this byte in MySQL 4.0.
recv_recovery_from_checkpoint_finish(): Call the new function
row_merge_drop_temp_indexes(), to drop all indexes whose name starts
with the byte 0xff.
row_merge_rename_indexes(): Renamed from row_merge_rename_index().
Remove the parameter "index".
row_drop_table_for_mysql(): Unconditionally call trx_commit_for_mysql().
row_drop_table_for_mysql_no_commit(): Correct the function commit,
based on the corrected comment of row_drop_table_for_mysql(). Rely on
table->to_be_dropped instead of TEMP_TABLE_PREFIX.
ha_innobase::add_index(): Simplify the control flow.
row_upd_index_is_referenced(), row_upd_check_references_constraints(),
row_purge_parse_undo_rec(): Remove duplicated code that calls
row_mysql_unfreeze_data_dictionary().
row_undo_ins_remove_clust_rec():
Assert that the data dictionary is X-latched. Do not attempt to re-latch
the data dictionary, because doing so introduces race conditions. This
re-latching was probably made unnecessary already in r1676, which keeps
the data dictionary X-latched in ha_innobase::add_index() for the complete
duration of the data dictionary operations.
row_undo_ins_parse_undo_rec(): Do not attempt to acquire the data dictionary
latch. The data dictionary should be already X-latched when a transaction
that modifies system tables is rolled back. This also holds in the rollback
during crash recovery: trx_rollback_active() will X-latch the data dictionary
when needed.
Replace row0merge.h with row0mysql.h.
Remove redundant test trx->dict_operation_lock_mode == 0.
Fix typos in comments.
row_undo_ins(): Make the function more similar to the one in trunk.
in the clustered index to be smaller than the indexed prefix in secondary
indexes.
row_ext_lookup(): Return NULL if the column is not stored externally.
trx_undo_rec_get_partial_row(): row_build(): Add parameter row_ext_t** ext.
row_build_index_entry(): Add the parameter row_ext_t* ext.
Invoke row_ext_lookup() to fetch prefixes of externally stored columns.
upd_node_t, undo_node_t, purge_node_t: Add the field row_ext_t* ext.
