with plugin-load-add that are already registered at mysql.plugin
- issue just one error message, without this extra warning
- don't abuse ER_UDF_EXISTS, instead add a proper error message for plugins
- report started initialization for each plugin source
When RENAME TABLE is executed, it apparently does not check whether the engine
is available (unlike ALTER TABLE .. RENAME, which does). It means that if the
engine in question was not loaded on some reason, the table might become
unusable, since the engine won't know about the change.
With this patch RENAME TABLE fails if storage engine is not available.
use the Alter_inplace_info::ALTER_COLUMN_OPTION flag if
field/column flags were altered.
change ha_example to use check_if_supported_inplace_alter() instead
of obsolete check_if_incompatible_data()
* update results
* don't force HA_CREATE_DELAY_KEY_WRITE on all temp tables,
(bad for CREATE ... LIKE) instead imply it in myisam/aria
* restore HA_ERR_TABLE_DEF_CHANGED in archive
* increase the default number of rwlock classes in P_S to fit all our rwlocks
USING THE PLUGIN INTERFACE.
ISSUE: No support for floating-point plugin
system variables.
SOLUTION: Allowing plugins to define and expose floating-point
system variables of type double. MYSQL_SYSVAR_DOUBLE
and MYSQL_THDVAR_DOUBLE are added.
ISSUE: Fractional part of the def, min, max values of system
variables are ignored.
SOLUTION: Adding functions that are used to store the raw
representation of a double in the raw bits of unsigned
longlong in a way that the binary representation
remains the same.

Put descriptions of plugins into a separate file read by MTR
MTR itself has generalised code to read this and set env. variables
Removed the *SO variables, updated some tests accordingly
New commit: added optional list of plugin names for _LOAD variable
Also made changes for the new AUTH_* plugins
* fully support --mysqld=--plugin-load=xxxx
* uniformly support all loadable plugins, no need to hard-code
every new plugin in mtr
* autodetect MTR_VS_CONFIG on windows
consistency: don't use "index" and "key" interchangeably
=> rename "key" to "index"
consistency: all option types are logical, besides ULL
=> rename ULL to NUMBER
don't accept floats where integers are expected
accept hexadecimal where integers are expected

- Remove the "hack" from mtr.pl that skipped searching for the .dll files
when embedded and windows. Now the variables will be preoperly initialized.
- Make the tests detect that they can't run on windows+embedded
Remove custom DLL loader code from innodb plugin code, use
symbols exported from mysqld.

value of TLS variable across DLL boundaries is

If setting a system-variable provided by a plug-in failed, no OK or
error was sent in some cases, hanging the client. We now send an error
in the case from the ticket (integer-argument out of range in STRICT
mode). We also provide a semi-generic fallback message for possible
future cases like this where an error is signalled, but no message is
sent to the client. The error/warning handling is unified so it's the
same again for variables provided by plugins and those in the server
proper.
mysql-test/r/plugin.result:
show that on out-of-range values, plugin interface throws errors
in STRICT mode and warnings otherwise.
mysql-test/t/plugin.test:
show that on out-of-range values, plugin interface throws errors
in STRICT mode and warnings otherwise.
sql/set_var.cc:
- handle signedness of values used in warnings
- in STRICT mode, throw errors rather than warnings
sql/sql_parse.cc:
If sql_set_variables() returns with an error but no message
was sent to the client, send a semi-generic one so the session
won't hang and we won't fail silently.
sql/sql_plugin.cc:
throw a warning if more than just block-size was corrected
(or an error in STRICT mode). use functions from set_var
for uniform behaviour of server- and plug-in variables.
storage/example/ha_example.cc:
Add a ULONG system variable to example plugin so
we can test integers in the plugin-interface without
having to depend on the presence of innobase.
storage engine system variables was not validated and
unexpected value was assigned.
The check_func_enum function used subtraction from the uint
value with the probably negative result. That result of
type uint was compared with 0 after casting to signed long
type. On architectures where long type is longer than int
type the result of comparison was unexpected.
storage/example/ha_example.cc:
Fixed bug #32034.
Sample system variable example_enum_var has been added to the
EXAMPLE storage to test ENUM variables.
sql/sql_plugin.cc:
Fixed bug #32034.
The check_func_enum function used subtraction from the uint
value with the probably negative result. That result of
type uint was compared with 0 after casting to signed long
type. On architectures where long type is longer than int
type the result of comparison was unexpected.
uint value has been casted to long type before subtraction.

mysql-test/r/plugin.result:
Added test case for bug #32034.
- Added suppressions for dlopen to make plugin test pass.
- Do not pass empty string to mysqld, since my_getopt is
not capable to handle it.
- Re-enabled trailing UNINSTALL PLUGIN statement of plugin.test.
The memory leak described in the bug report happens in libdl, not
in mysqld. On some valgrind installations this error is suppressed
by default, no idea why it isn't suppressed on pb-valgrind.
<observation>
If library remains open after thread has finished, and is closed by
another thread, we get memory leak. But in case library is opened and
closed by the same thread no leak occurs.
</observation>
mysql-test/lib/mtr_io.pl:
Do not pass empty string since my_getopt is not capable to handle it.
This is required to make plugin.test work on platforms where
ha_example is not compiled.
mysql-test/r/plugin.result:
Updated test result.
mysql-test/t/plugin.test:
Re-enabled UNINSTALL PLUGIN statement. It is a good idea to cleanup
at the end of the test. Anyway bug22694 was fixed while this test
was disabled.
mysql-test/valgrind.supp:
Added suppressions for dlopen to make plugin test pass.
