This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.
This is allowed:
STRING_WITH_LEN("string literal")
This is not:
char *str = "pointer to string";
... STRING_WITH_LEN(str) ..
In C++ this is also allowed:
const char str[] = "string literal";
... STRING_WITH_LEN(str) ...
clang15 finally errors on old prototype definations.
Its also a lot fussier about variables that aren't used
as is the case a number of time with loop counters that
aren't examined.
RocksDB was complaining that its get_range function was
declared without the array length in ha_rocksdb.h. While
a constant is used rather than trying to import the
Rdb_key_def::INDEX_NUMBER_SIZE header (was causing a lot of
errors on the defination of other orders). If the constant
does change can be assured that the same compile warnings will
tell us of the error.
The ha_rocksdb::index_read_map_impl DBUG_EXECUTE_IF was similar
to the existing endless functions used in replication tests.
Its rather moot point as the rocksdb.force_shutdown test that
uses myrocks_busy_loop_on_row_read is currently disabled.
The bug is caused by a similar mechanism as MDEV-21027.
The function, check_insert_or_replace_autoincrement, failed to open
all the partitions on REPLACE SELECT statements and it results in the
assertion error.
Fixing a few problems relealed by UBSAN in type_float.test
- multiplication overflow in dtoa.c
- uninitialized Field::geom_type (and Field::srid as well)
- Wrong call-back function types used in combination with SHOW_FUNC.
Changes in the mysql_show_var_func data type definition were not
properly addressed all around the code by the following commits:
b4ff64568c18feb62fee0ee879ff8a
Adding a helper SHOW_FUNC_ENTRY() function and replacing
all mysql_show_var_func declarations using SHOW_FUNC
to SHOW_FUNC_ENTRY, to catch mysql_show_var_func in the future
at compilation time.
- Added missing information about database of corresponding table for various types of commands
- Update some typos

ha_partition::set_auto_increment_if_higher expects
part_share->auto_inc_initialized is true or can_use_for_auto_inc_init()
is false (but as the comment of this method says, it returns false
only if we use Spider engine with DROP TABLE or ALTER TABLE query).
However, part_share->auto_inc_initialized becomes true only after all
partitions are opened (since 6dce6aeceb).
Therefore, I added a conditional expression in order to read all
partitions when we execute REPLACE on a table that has an
AUTO_INCREMENT column.

failed for TokuDB engine CREATE TABLE
Analysis: Assertion failure happens because the database doesn't exist to
create the table but ha_tokudb::create() still returns false.
So error is not reported.
Fix: Store the error state and report the error.
The assertion failed in handler::ha_reset upon SELECT under
READ UNCOMMITTED from table with index on virtual column.
This was the debug-only failure, though the problem is mush wider:
* MY_BITMAP is a structure containing my_bitmap_map, the latter is a raw
bitmap.
* read_set, write_set and vcol_set of TABLE are the pointers to MY_BITMAP
* The rest of MY_BITMAPs are stored in TABLE and TABLE_SHARE
* The pointers to the stored MY_BITMAPs, like orig_read_set etc, and
sometimes all_set and tmp_set, are assigned to the pointers.
* Sometimes tmp_use_all_columns is used to substitute the raw bitmap
directly with all_set.bitmap
* Sometimes even bitmaps are directly modified, like in
TABLE::update_virtual_field(): bitmap_clear_all(&tmp_set) is called.
The last three bullets in the list, when used together (which is mostly
always) make the program flow cumbersome and impossible to follow,
notwithstanding the errors they cause, like this MDEV-17556, where tmp_set
pointer was assigned to read_set, write_set and vcol_set, then its bitmap
was substituted with all_set.bitmap by dbug_tmp_use_all_columns() call,
and then bitmap_clear_all(&tmp_set) was applied to all this.
To untangle this knot, the rule should be applied:
* Never substitute bitmaps! This patch is about this.
orig_*, all_set bitmaps are never substituted already.
This patch changes the following function prototypes:
* tmp_use_all_columns, dbug_tmp_use_all_columns
to accept MY_BITMAP** and to return MY_BITMAP * instead of my_bitmap_map*
* tmp_restore_column_map, dbug_tmp_restore_column_maps to accept
MY_BITMAP* instead of my_bitmap_map*
These functions now will substitute read_set/write_set/vcol_set directly,
and won't touch underlying bitmaps.

Implement a different fix for
"MDEV-19232: Floating point precision / value comparison problem"
Instead of truncating decimal values after every division,
truncate them for comparison purposes.
This reverts commit 62d73df6b2 but keeps the test.
