in r2276. Now the following symbols will be exported when InnoDB is built
as a dynamic plugin:
* the virtual method pointer table of class ha_innodb
* the three variables that MySQL will reference when linking at runtime:
_mysql_plugin_declarations_
_mysql_plugin_interface_version_
_mysql_sizeof_struct_st_plugin_
Furthermore, the following symbols are weak globals, to allow us to access
the built-in InnoDB in the mysqld executable, in case it contains a statically
linked InnoDB:
builtin_innobase_plugin
innodb_hton_ptr
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.
dtuple_validate(): Detect uninitialized data.
page_cur_insert_rec_low(), page_cur_insert_rec_zip(): Assert that the
record being inserted is valid before and after insertion.
Fix a bug where the condition (prtype & DATA_ROW_ID) is unexpectedly
always false becasue DATA_ROW_ID is 0.
Use a switch instead of if-else in order to avoid repeating
(prtype & DATA_SYS_PRTYPE_MASK).

dtuple_create_for_mysql(), dtuple_free_for_mysql(): Remove.
ha_innobase::records_in_range(): Use mem_heap_create(), mem_heap_free(),
and dtuple_create() instead of the removed functions above. Since r1587,
InnoDB C++ functions can invoke inlined C functions.
mem_heap_zalloc() and mem_zalloc(), because calloc() in the C runtime
library takes two size parameters, not one.
mem_heap_zalloc(): Add debug assertions. Document that the return value
is never NULL.
Some things still fail in innodb-index.test, and there seems to be
a race condition (data dictionary lock wait) when running with --valgrind.
dfield_t: Add an "external storage" flag, dfield->ext.
dfield_is_null(), dfield_is_ext(), dfield_set_ext(), dfield_set_null():
New functions.
dfield_copy(), dfield_copy_data(): Add const qualifiers, fix in/out comments.
data_write_sql_null(): Use memset().
big_rec_field_t: Replace byte* data with const void* data.
ut_ulint_sort(): Remove.
upd_field_t: Remove extern_storage.
upd_node_t: Replace ext_vec, n_ext_vec with n_ext.
row_merge_copy_blobs(): New function.
row_ins_index_entry(): Add the parameter "ibool foreign" for suppressing
foreign key checks during fast index creation or when inserting into
secondary indexes.
btr_page_insert_fits(): Add const qualifiers.
btr_cur_add_ext(), upd_ext_vec_contains(): Remove.
dfield_print_also_hex(), dfield_print(): Replace if...else if with switch.
Observe dfield_is_ext().
now that all of InnoDB code is built from a single Makefile and it should
not be possible to build the modules with mutually incompatible options.
#define INSIDE_HA_INNOBASE_CC: Remove.
srv_sizeof_trx_t_in_ha_innodb_cc: Remove.
dict_table_get_low_noninlined(): Remove. This function was unused.
Remove all _noninline functions. Remove the _noninline suffix from
all function calls in ha_innodb.cc.
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 externally stored columns, and fix bugs introduced in r873. (Bug #22496)

rec_get_converted_size(), rec_convert_dtuple_to_rec(),
rec_convert_dtuple_to_rec_old(), rec_convert_dtuple_to_rec_new():
Add parameters ext and n_ext. Flag external fields during the
conversion.
rec_set_field_extern_bits(), rec_set_field_extern_bits_new(),
rec_offs_set_nth_extern(), rec_set_nth_field_extern_bit_old():
Remove. The bits are set by rec_convert_dtuple_to_rec().
page_cur_insert_rec_low(): Remove the parameters ext and n_ext.
btr_cur_add_ext(): New utility function for updating and sorting ext[].
Low-level functions now expect the array to be in ascending order
for performance reasons. Used in btr_cur_optimistic_insert(),
btr_cur_pessimistic_insert(), and btr_cur_pessimistic_update().
btr_cur_optimistic_insert(): Remove some defensive code, because we cannot
compute the added parameters of rec_get_converted_size().
btr_push_update_extern_fields(): Sort the array. Require the array to
be twice the maximum usage, so that ut_ulint_sort() can be used.
dtuple_convert_big_rec(): Allocate new space for the BLOB pointer,
to avoid overwriting prefix indexes to the same column. Adapt
dtuple_convert_back_big_rec().
row_build_index_entry(): Fetch the columns also for prefix indexes of
the clustered index.
page_zip_apply_log(), page_zip_decompress_clust(): Allow externally
stored fields to lack a locally stored part.
of externally stored columns to REC_1BYTE_OFFS_LIMIT (128) bytes.

and store the entire column externally. (Bug #22496)
dict_col_t::min_prefix: Remove.
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.
data0data.c: Add #include "page0zip.h" that was forgotten from r739.
page_cur_insert_rec_low(): Remove a memory leak when preventing
extra_size to grow.
record will fit or need external storage.
btr_page_get_sure_split_rec(): Estimate the free space of an empty
compressed page.
page_zip_rec_needs_ext(): New function, to replace existing tests whether
external storage is needed.
Replace btr_page_get_level() with page_is_leaf() where possible.
row_purge_upd_exist_or_extern(): Remove obsolete TODO comment.
dtuple_convert_big_rec(): Replace a flag variable with goto.
