- Don't add DZSTD_STATIC_LINKING_ONLY
- Don't use upstream's way of linking with Jemalloc (MyRocks/MariaDB has
its own in build_rocksdb.cmake)
- Don't depend on libunwind

Skip valgrind for rocksdb.force_shutdown
Summary:
This test does unclean shutdown, and leaks memory.

Problem:
=========
One of the purge thread access the corrupted page and tries to remove from
LRU list. In the mean time, other purge threads are waiting for same page
in buf_wait_for_read(). Assertion(buf_fix_count == 0) fails for the
purge thread which tries to remove the page from LRU list.
Solution:
========
- Set the page id as FIL_NULL to indicate the page is corrupted before
removing the block from LRU list. Acquire hash lock for the particular
page id and wait for the other threads to release buf_fix_count
for the block.
- Added the error check for btr_cur_open() in row_search_on_row_ref().
Before killing the server, ensure that the incomplete state of
the transaction will be made durable and will be applied and
rolled back on recovery, so that each time, roughly the same
amount of work will be done.
Remove DML statements after the recovery, and execute
CHECK TABLE instead.
Remove the test, because it easily fails with a result difference.
Analysis by Thirunarayanan Balathandayuthapani:
By default, innodb_encrypt_tables=0.
1) Test case creates 100 tables in innodb_encrypt_1.
2) creates another 100 unencrypted tables (encryption=off) in innodb_encrypt_2
3) creates another 100 encrypted tables (encryption=on) in innodb_encrypt_3
4) enabling innodb_encrypt_tables=1 and checking that only
100 encrypted tables exist. (already we have 100 in dictionary)
5) opening all tables again (no idea why)
6) After that, set innodb_encrypt_tables=0 and wait for 100 tables
to be decrypted (already we have 100 unencrypted tables)
7) dropping all databases
Sporadic failure happens because after step 4, it could encrypt the
normal table too, because innodb_encryption_threads=4.
This test was added in MDEV-9931, which was about InnoDB startup being
slow due to all .ibd files being opened. There have been a number of
later fixes to this problem. Currently the latest one is
commit cad56fbaba, in which some tests
(in particular the test innodb.alter_kill) could fail if all InnoDB
.ibd files are read during startup. That could make this test redundant.
Let us remove the test, because it is big, slow, unreliable, and
does not seem to reliably catch the problem that all files are being
read on InnoDB startup.
GCC 9.1.1 noticed that sd_notifyf() was always being invoked with
str=NULL argument for "%s". This code was added in
commit 2e814d4702
but not mentioned in the commit comment.
The STATUS messages for systemd matter during startup and shutdown,
and should not be emitted during normal operation.
ib_senderrf(): Remove the potentially harmful sd_notifyf() calls.
innodb_locks_unsafe_for_binlog variabe removed from wsrep_info test configuration and
recommendation to use this variable in README-wsrep was removed as well
Also relates to issue: MDEV-19544
This patch fixes 10.2 issue reported in MDEV-16467 by partial backport of
c2118a0. Specifically "Remove not needed LOCK_thread_count from
thd_get_error_context_description()".
- If InnoDB encounters garbage or incomplete written log block during
recovery then don't throw the error. Treat it as end of the log.
- This kind of incomplete or empty block can be result of killing
InnoDB when writing the redo log.
Some I/O functions and macros that are declared in os0file.h used to
return a Boolean status code (nonzero on success). In MySQL 5.7, they
were changed to return dberr_t instead. Alas, in MariaDB Server 10.2,
some uses of functions were not adjusted to the changed return value.
Until MDEV-19231, the valid values of dberr_t were always nonzero.
This means that some code that was incorrectly checking for a zero
return value from the functions would never detect a failure.
After MDEV-19231, some tests for ALTER ONLINE TABLE would fail with
cmake -DPLUGIN_PERFSCHEMA=NO. It turned out that the wrappers
pfs_os_file_read_no_error_handling_int_fd_func() and
pfs_os_file_write_int_fd_func() were wrongly returning
bool instead of dberr_t. Also the callers of these functions were
wrongly expecting bool (nonzero on success) instead of dberr_t.
This mistake had been made when the addition of these functions was
merged from MySQL 5.6.36 and 5.7.18 into MariaDB Server 10.2.7.
This fix also reverts commit 40becbc3c7
which attempted to work around the problem.
Handling of top level conjuncts in WHERE whose used_tables() contained
RAND_TABLE_BIT in the function make_join_select() was incorrect.
As a result if such a conjunct referred to fields non of which belonged
to the last joined table it was pushed twice. (This could be seen
for a test case from subselect.test whose output was changed after this
patch had been applied. In 10.1 when running EXPLAIN FORMAT=JSON for
the query from this test case we clearly see that one of the conjuncts
is pushed twice.) This fact by itself was not good. Besides, if such a
conjunct was pushed to a table that was the result of materialization
of a semi-join the query could return a wrong result set. In particular
we could watch it for queries with semi-join subqueries whose left parts
used stored functions without "deterministic' specifier.
Those two may work incorrectly together. Namely, ASAN may produce
false positives or false negatives. For details see

Problem:
=======
fil_iterate() writes imported tablespace page0 as it is to discarded
tablespace. Space id wasn't even changed. While opening the tablespace,
tablespace fails with space id mismatch error.
Fix:
====
fil_iterate() copies the page0 with discarded space id to imported
tablespace.
fix MDEV-18750: failed to flashback large-size binlog file
fix mysqlbinlog flashback failure caused by reading io_cache without MY_FULL_IO flag
fix MDEV-18750: mysqlbinlog flashback failure on large binlog
Adding destructor for Group_bound_tracker to free Cached_item_str.
The Cached_item for window functions are allocated on THD:mem_root
but the Cached_item_str has value of type string which is allocated on
the heap, so we need to call free() for it
os_file_write_func() and os_file_read_no_error_handling_func() returned
different result values depending on if UNIV_PFS_IO was defined or not.
Other things:
- Added some comments about return values for some functions
