Added option --user-args, to be used with --start*

Also added missing help text entry for --start-and-exit

There were two problems:
- a mistake during merge of a patch for Bug 52629 from 5.1;
- MTR treated auxilary output of newer valgrind as an error.
The fixes are:
- Fix merge error;
- Teach MTR to skip 'HEAP summary' section of valgrind output.
data directory name command
The check_db_name function has been modified to validate tails of
#mysql50#-prefixed database names for compliance with MySQL 5.0
database name encoding rules (the check_table_name function call
has been reused).
Problem: The test case mysqldump reads a file that must
be world-readable. The test did not force the file to be
world-readable, so if the tree was branched with a umask
of 0077, the test would fail.
Fix: chmod the file.
Server crashes on 64bit linux with 'double free or corruption'
message, on 32bit mysql-test-run silently fails on bootstrap
stage. The problem is that FreeState() is called twice
for init_settings struct in _db_end_ function.
The fix is to remove superfluous FreeState() call.
Additional fix:
fixed discrepancy of result file when
debug & valgrind options are enabled
for MTR.
(make relies GNU extentions). The patch was partially
backport from 6.0.
Original comment:
bug#30708: make relies GNU extensions. Now that we no longer use
BitKeeper we can safely remove the SCCS handling with no loss of
functionality.
Bug #50087 Interval arithmetic for Event_queue_element is not portable.
Subtraction of two unsigned months yielded a (very large) positive value.
Conversion of this to a signed value was not necessarily well defined.
Solution: do the subtraction on signed values.
Analysis showed that in case of accessing I_S table
ROUTINES we perform unnecessary allocations
with get_field() function for every processed row that
in their turn causes significant memory growth.
the fix is to avoid use of get_field().
That was a pure test issue -- filter implementation in Perl did not work
on some platform (the bug occurred on Windows Server 2008 with
Cygwin Perl 5.10.0).
mode
Post-push fix after backporting the patch to 5.1-bugteam:
1 - changed the name of some variables to be equivalent to pe.
2 - fixed that patch to mark a statement as unsafe when both a
self-logging eng. and regular eng. are accessed and one of them
is updated.
Post-fix: Updated a test case after the patch for BUG#50410,
because the patch makes ndb to run in the row format and as
such unsafe warning messages are not printed out.
multiquery packet).
Background:
- a query can contain multiple SQL statements;
- the server frees resources allocated to process a query when the
whole query is handled. In other words, resources allocated to process
one SQL statement from a multi-statement query are freed when all SQL
statements are handled.
The problem was that the parser allocated a buffer of size of the whole
query for each SQL statement in a multi-statement query. Thus, if a query
had many SQL-statements (so, the query was long), but each SQL statement
was short, ther parser tried to allocate huge amount of memory (number of
small SQL statements * length of the whole query).
The memory was allocated for a so-called "cpp buffer", which is intended to
store pre-processed SQL statement -- SQL text without version specific
comments.
The fix is to allocate memory for the "cpp buffer" once for all SQL
statements (once for a query).

UPDATE bug 14272.
Same resolution as for the bug 14272:
Don't run index scan when we should use quick select.
This could cause failures because there are table handlers (like federated)
that support quick select scanning but do not support index scanning.
for ALTER TABLE, LOAD DATA).
ROW_COUNT is now assigned according to the following rules:
- In my_ok():
- for DML statements: to the number of affected rows;
- for DDL statements: to 0.
- In my_eof(): to -1 to indicate that there was a result set.
We derive this semantics from the JDBC specification, where int
java.sql.Statement.getUpdateCount() is defined to (sic) "return the
current result as an update count; if the result is a ResultSet
object or there are no more results, -1 is returned".
- In my_error(): to -1 to be compatible with the MySQL C API and
MySQL ODBC driver.
- For SIGNAL statements: to 0 per WL#2110 specification. Zero is used
since that's the "default" value of ROW_COUNT in the diagnostics area.
MTR sporadically reported that rpl_do_grant does not
clean up after itself.
We fix this by backporting BUG 50984 fix. This deploys
missing synchronization between master and slave.
Additionally, it also fixes the check_testcase for
rpl_tmp_table_and_DDL.
NULL from outer join query
Problem: optimising MIN/MAX() queries without GROUP BY clause
by replacing the aggregate expression with a constant, we may set it
to NULL disregarding the fact that there may be outer joins involved.
Fix: don't replace MIN/MAX() with NULL if there're outer joins.
Note: the fix itself is just
- if (!count)
+ if (!count && !outer_tables)
set to NULL
The rest of the patch eliminates repeated code to improve speed
and for easy maintenance of the code.
- Update/fix file layouts for each package type, add new types for
native package formats including deb, rpm and svr4.
- Build all plugins, including debug versions
- Update compiler flags to match current release
- Add missing @VAR@ expansions
- Install correct mysqclient library symlinks
- Fix icc/ia64 builds
- Fix install of libmysqld-debug
- Don't include mysql_embedded
- Remove unpackaged manual pages to avoid missing files warnings
- Don't install mtr's test suite
with other merges from the old distribution-specific spec file.
- update copyright notices
- remove __os_install_post override, it was only necessary as a
hack to build debuginfo packages - now that we no longer make
them we can revert to the distribution macro which likely has
other useful bits we might want
- remove _unpackaged_files_terminate_build override, we want to
know of any orphaned files
- include native distribution support
- no longer build separate debuginfo RPMs, instead just include
debug/symbols in all binaries, which is more useful for support
- include support for building commercial RPMs, requires a
commercial source tree
- remove cluster RPM support, we don't build them from this
source tree
- use CMake for building, and update package lists to match the
new install layout/files. Remove any options which were only
useful for automake builds (e.g. yassl/zlib).
- other minor cleanups
