- Fixed the checks to properly check for plugin_dir containing a trailing slash or backslash.
- Fixed a under-configuration in udf_skip_grants that was preventing the test
from running even when there was a udf plugin.
(server crash)
Altering a table with fulltext index[es] which use
pluggable fulltext parser may cause server crash
in debug builds.
The problem was that ALTER TABLE code wrongly assigned
fulltext parser name.
Also fixed that altering a table with fulltext index[es]
leave stale fulltext parser locks, which prevent
fulltext parsers from being uninstalled after
ALTER TABLE.
