interpreter. It was only used for updating the InnoDB internal data
dictionary when renaming or dropping tables. It could have caused
deadlocks after acquiring latches on insert buffer bitmap pages.
This and r3544 should fix Issue #135.
Furthermore, the update-in-place-in-select does not account for
compression failure. That was not a problem yet, since the InnoDB SQL
interpreter has so far assumed ROW_FORMAT=REDUNDANT.

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.
of the InnoDB SQL parser.
pars_is_string_type(): New function. Returns TRUE iff mtype equals
DATA_VARCHAR, DATA_CHAR, DATA_FIXBINARY, or DATA_BINARY.
pars_resolve_func_data_type(): Replace checks for DATA_VARCHAR with
pars_is_string_type(). For example, the NAME column of SYS_INDEXES,
SYS_TABLES, and SYS_COLUMNS is of DATA_BINARY type, although it
contains a UTF-8 character string. This affects the functions
TO_NUMBER, BINARY_TO_NUMBER, LENGTH, INSTR, and SUBSTR.
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".
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.
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.
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.
