not know there's rollback (if it's because of a dupl row), better warn
that it's happening. It can also be of use for a DBA killing a
connection and wondering what this connection is still doing now. Example:
| 5 | root | localhost | test | Killed | 10 | Rolling back | insert into i select * from j |
Bug #6479 ALTER TABLE ... changing charset fails for TEXT columns
Fix: use do_conv_blob rather than do_copy_blob
if the column's character sets are different.
created new facade object for CommandInterpreter
removed CPC #if 0 code
removed editline from mgmtsrver, no replace with readline since interface is obsolete anyways
1) fix so that missing blob tables don't prevent table from being
dropped
2) decrease size of blob part if record length exceeds max length
3) add test case for table wo/ corresponding blob table
4) init scan counters when sending scan_tabreq
Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root
Included header fnmatch.h on Unix
Changed C++ comments to C comments
Corrected indentation of code written on Windows
Split up lines to fit into 80 columns
Initiated some variables to avoid warnings
Added __attribute__((unused)) to unused function parameters
Replace tab characters with space
Put space after 'for', 'while' etc
Added value to 'return' from non void function removef()
On Unix strlwr() was incorrectly declared and a no op,
replaced it with a macro that does nothing
Split several statements on the same line
Other minor changes to conform to coding standard
Added cases for bugs #6307 and #6460.
sql_select.cc:
Fixed the problem of bug reports #6307 and #6460.
The reported wrong result sets were due to the fact that
the added call of the fix_fields method for the built
AND condition that joined WHERE and ON conditions
broke ON expression, as it removed extra AND levels
in the built condition.
It looks like that no attributes of the built condition
are needed, so we don't have to call fix_fields here.
of client equals to character set of connection, possibly required
conversion to character set of column is not performed
(prepared statements, data is supplied using placeholders).
My previous change that "set @a=NULL" doesn't change charset
fixed 'Bug #6321' as well. Prove with a new test that
FIELD(<uservariable content NULL>, ...) now works fine too.
_all_ versions. It tries to remove "Docs/Images/Makefile*" as part of the actions to
correct bug number 6350. If the source tree does not contain a dummy file matching
that pattern, this "rm" will fail, and so "Bootstrap" will fail.
The "Makefile.am" introduced with this changeset is identical to the one that will
arrive here when "joerg:1.2057" is propagated from 4.0,
so this separate introduction here is just to allow "Bootstraps" in the meantime.
character set with NULL, @a should be latin2
after this query sequence:
SET @a=_latin2'string';
SET @a=NULL;
I.e. the second query should not change the charset
to the current default value, but should keep the
original value assigned during the first query.
In order to do it, we don't copy charset
from the argument if the argument is NULL
and the variable has previously been initialized.
