The patch for WL 1563 added a new duplicate key error message so that the
key name could be provided instead of the key number. But the error code
for the new message was used even though that did not need to change.
This could cause unnecessary problems for applications that used the old
ER_DUP_ENTRY error code to detect duplicate key errors.
and invalidation in the most general case (non-temporary table and
not simple RENAME or ENABLE/DISABLE KEYS or partitioning command).
See comment for sql/sql_table.cc for more information.
These changes are prerequisite for 5.1 version of fix for bug #23667
"CREATE TABLE LIKE is not isolated from alteration by other connections"
TABLES" and failures of alter_table.test on Windows which occured after
pushing fix for bugs #20662, #20903, #24508, #24738 (various problems
with CREATE TABLE SELECT).
ALTER TABLE statements which were handled using "fast" alter table
optimization were not properly working under LOCK TABLES if table
was transactional (for all table types under Windows).
Code implementing "fast" version of ALTER TABLE tried to open and
lock table using open_ltable() after renaming .FRM files (which
corresponds to renaming tables in normal case) in some cases
(for transactional tables or on Windows). This caused problems
under LOCK TABLES and conflicted with name-lock taken by
ALTER TABLE RENAME on target tables.
This patch solves this issue by using reopen_name_locked_table()
instead of open_ltable().
WL#3397 Refactoring storage engine test cases (for falcon)
It contains fixes according to second code review.
- Remove any occurence of hardcoded assignments of storage engines
- Use variable names exact telling what it is used for
- Updated comments
- remove trailing spaces
WL#3397 Refactoring storage engine test cases (for falcon)
It contains also fixes according to code review.
Contents: Testcases which were in history dedicated to InnoDB or MyISAM only.
Modifications:
1. Shift the main testing code into include/<testing field>.inc
Introduce $variables which can be used to omit tests for features which are not supported by
certain storage engines.
2. The storage engine to be tested is assigned within the toplevel script (t/<whatever>_<engine>.test)
via variable $engine_type and the the main testing code is sourced from
include/<testing field>.inc
3. Some toplevel testscripts have to be renamed to
- avoid immediate or future namespace clashes
- show via filename which storage engine is tested
4. Minor code cleanup like remove trailing spaces, some additional comments ....
