mysqladmin's presumption about the cause of an error by looking
at the error code was presumptious. Server knows best, so pass
the error along.
Avoid returning -1 as a exit code, Linux makes this 255 and Windows
keeps this as -1.
make TRANSACTIONAL table option behave similar to other engine-defined
table options. If the engine doesn't suport it:
* if specified expicitly in CREATE or ALTER - it's ER_UNKNOWN_OPTION
* an error or a warning depending on sql_mode IGNORE_BAD_TABLE_OPTIONS
* in ALTER TABLE from the engine that suppors it to the engine that
doesn't - silently preserved (no warning)
* it is commented out in SHOW CREATE unless IGNORE_BAD_TABLE_OPTIONS
differently react to SQL_MODE => unusable SHOW CREATE
Use abort_on_warning dependent on strict mode over create new table
like it is done for copy data and inplace alter.
MDEV-28227 added the error messages in simplified characters.
Lets use these for those running a zh_CN profile.
From Haidong Ji in the MDEV, Taiwan/Hong Kong (zh_TW/zh_HK)
would expect traditional characters so this is left for when
we have these.
plugin_vars_free_values() was walking plugin sysvars and thus
did not free memory of plugin PLUGIN_VAR_NOSYSVAR vars.
* change it to walk all plugin vars
* add the pluginname_ prefix to NOSYSVARS var names too,
so that plugin_vars_free_values() would be able to find their
bookmarks
The problem happened because the the new client capability flag
CLIENT_EXTENDED_METADATA was not put into the cache entry key.
So results cached by a new client were sent to the old client (and vica versa)
with a mis-matching metadata, which made the client abort the connection on
an unexpected result set metadata packet format.
The problem was caused by the patch for:
MDEV-17832 Protocol: extensions for Pluggable types and JSON, GEOMETRY
which forgot to adjust the query cache code.
Fix:
- Adding a new member Query_cache_query_flags::client_extended_metadata,
so only clients with equal CLIENT_EXTENDED_METADATA flag values can
reuse results.
- Adding a new column CLIENT_EXTENDED_METADATA into
INFORMATION_SCHEMA.QUERY_CACHE_INFO (privided by the qc_info plugin).
SET PASSWORD = PASSWORD('foo') would fail for pam plugin with
ERROR HY000: SET PASSWORD is ignored for users authenticating via pam plugin
but SET PASSWORD = 'foo' would not.
Now it will.
