1) Ensure "init_db.sql" and "test_db-sql" really get built.
2) Ensure the "*.def" files with NetWare linker options get distributed to the proper directories.
1) We do not provide the "isam" table handler in 5.0 and up (different from "myisam" !),
so we do not need the ".def" files for the "isam"-specific tools.
2) Use "basename" to get the base name of a file, not a harder-to-read sed expression.
Killing a SELECT query with KILL QUERY or KILL CONNECTION
causes a server crash if the query cache is enabled.
Normal evaluation of a query may be interrupted by the
KILL QUERY/CONNECTION statement, in this case the mysql_execute_command
function returns TRUE, and the thd->killed flag has true value.
In this case the result of the query may
be cached incompletely (omitting call to query_cache_insert inside
the net_real_write function), and next call to query_cache_end_of_result
may lead to server crash.
Thus, the query_cache_end_of_result function has been modified to abort
query cache in the case of killed thread.
Although the query cache doesn't support retrieval of statements containing
column level access control, it was still possible to cache such statements
thus wasting memory.
This patch extends the access control check on the target tables to avoid
caching a statement with column level restrictions.
Views are excepted and can be cached but only retrieved by super user account.

This is a follow up for the patch for Bug#26162 "Trigger DML ignores low_priority_updates setting", where the stored procedure ignores the session setting of low_priority_updates.
For every table open operation with default write (TL_WRITE_DEFAULT) lock_type, downgrade the lock type to the session setting of low_priority_updates.
Apply innodb-5.0-ss1696 snapshot
Fixes:
- Bug#20090: InnoDB: Error: trying to declare trx to enter InnoDB
- Bug#23710: crash_commit_before fails if innodb_file_per_table=1
At InnoDB startup consider the case where log scan went beyond
checkpoint_lsn as a crash and initiate crash recovery code path.
- Bug#28781: InnoDB increments auto-increment value incorrectly with ON DUPLICATE KEY UPDATE
We need to do some special AUTOINC handling for the following case:
INSERT INTO t (c1,c2) VALUES(x,y) ON DUPLICATE KEY UPDATE ...
We need to use the AUTOINC counter that was actually used by
MySQL in the UPDATE statement, which can be different from the
value used in the INSERT statement.
- Bug#29097: fsp_get_available_space_in_free_extents() is capped at 4TB
Fix by typecasting the variables before multiplying them, so that the
result of the multiplication is of type "unsigned long long".
- Bug#29155: Innodb "Parallel recovery" is not prevented
Fix by enabling file locking on FreeBSD. It has been disabled because
InnoDB has refused to start on FreeBSD & LinuxThreads, but now it
starts just fine.
The bug caused memory corruption for some queries with top OR level
in the WHERE condition if they contained equality predicates and
other sargable predicates in disjunctive parts of the condition.
The corruption happened because the upper bound of the memory
allocated for KEY_FIELD and SARGABLE_PARAM internal structures
containing info about potential lookup keys was calculated incorrectly
in some cases. In particular it was calculated incorrectly when the
WHERE condition was an OR formula with disjuncts being AND formulas
including equalities and other sargable predicates.
