To fix the crash there we need to make sure that the
server while storing the statistical values in statistical tables should do it
in a multi-byte safe way.
Also there is no need to throw warnings if there is truncation while storing
values from statistical fields.
remove TABLE_SHARE::error_table_name() and TABLE_SHARE::orig_table_name
(that was allocated in a wrong memroot in this bug).
instead, simply set TABLE_SHARE::table_name correctly.
The error message modified.
Then the TABLE_SHARE::error_table_name() implementation taken from 10.3,
to be used as a name of the table in this message.
- clean up DEFAULT() to work only with default value and correctly print
itself.
- fix of DBUG_ASSERT about fields read/write
- fix of field marking for write based really on the thd->mark_used_columns flag
Problem was that Create_field::create_length_to_internal_length()
calculated a different pack_length for NEWDECIMAL compared to
Field_new_decimal constructor which lead to some unused bytes
in the middle of the record, which Aria didn't like.
for the small InnoDB table
This bug was introduced by the patch 6c414fcf89.
The patch has not taken into account that some objects of the Field_* types
are created only for TABLE_SHARE and the field 'table' is set to NULL
for them. In particular such are objects created to store statistical
min/max values for columns.
* get_rec_bits() was always reading two bytes, even if the
bit field contained only of one byte
* In various places the code used field->pack_length() bytes
starting from field->ptr, while it should be field->pack_length_in_rec()
* Field_bit::key_cmp and Field_bit::cmp_max passed field_length as
an argument to memcmp(), but field_length is the number of bits!
Other things, mainly to get
create_mysqld_error_find_printf_error tool to work:
- Added protection to not include mysqld_error.h twice
- Include "unireg.h" instead of "mysqld_error.h" in server
- Added protection if ER_XX messages are already defined
- Removed wrong calls to my_error(ER_OUTOFMEMORY) as
my_malloc() and my_alloc will do this automatically
- Added missing %s to ER_DUP_QUERY_NAME
- Removed old and wrong calls to my_strerror() when using
MY_ERROR_ON_RENAME (wrong merge)
- Fixed deadlock error message from Galera. Before the extra
information given to ER_LOCK_DEADLOCK was missing because
ER_LOCK_DEADLOCK doesn't provide any extra information.
I kept #ifdef mysqld_error_find_printf_error_used in sql_acl.h
to make it easy to do this kind of check again in the future
Fixing the asymmetry in the array field_types_merge_rules[][]
which caused data loss when mixing FLOAT + BIGINT in UNIONs
or hybrid functions:
1. FLOAT + INT = DOUBLE
2. FLOAT + BIGINT = FLOAT
3. INT + FLOAT = DOUBLE
4. BIGINT + FLOAT = DOUBLE
Now FLOAT + BIGINT (as in #2) also produces DOUBLE, like the cases #1,#3,#4 do.
- Fix win64 pointer truncation warnings
(usually coming from misusing 0x%lx and long cast in DBUG)
- Also fix printf-format warnings
Make the above mentioned warnings fatal.
- fix pthread_join on Windows to set return value.
Implement Field_timestamp::save_in_field(timestamp_field)
that stores timestamp values without converting them to MYSQL_TIME
and back, because this conversion is lossy around DST change time.
This fixes main.old-mode test.
This is 10.2 version of f8a800bec8
make insert NULL into a timestamp mark the field as having an
explicit value. So that the field won't be assigned the value
again in TABLE::update_default_field()
make Item_func_now_local::save_in_field(timestamp_field) not to go
through MYSQL_TIME - this conversion is lossy around DST change times.
This fixes inserting a default value into a timestamp field.
