When binding to NULL, DEFAULT or IGNORE from an Item value, Item_param did not
change m_type_handler, so its value remained from the previous bind.
Thid led to DBUG_ASSERTs in Item_param::get_date() and
Timestamp_or_zero_datetime_native_null.
Fix:
Set Item_param::m_type_handler to &type_handler_null when
binding from an Item returning NULL.
This patch also fixes MDEV-35427.
btr_cur_t::search_leaf(): In the BTR_SEARCH_PREV and BTR_MODIFY_PREV
modes, reset the previous search status before invoking
page_cur_search_with_match(). Otherwise, we the search could invoke
in a totally wrong subtree.
This fixes a regression that was introduced in
commit de4030e4d4 (MDEV-30400).
buf_block_alloc(): Define as an alias in buf0lru.h, which defines

Instead of repurposing buf_page_t::access_time for state()==MEMORY
blocks that are part of recv_sys.pages, let us define an anonymous
union around buf_page_t::hash. In this way, we will be able to
declare access_time private.

row_purge_remove_sec_if_poss_leaf(): If there is an active transaction
that is not newer than PAGE_MAX_TRX_ID, return the bogus value 1
so that row_purge_remove_sec_if_poss_tree() is guaranteed to recheck if
the record needs to be purged. It could be the case that an active
transaction would insert this record between the time this check
completed and row_purge_remove_sec_if_poss_tree() acquired a latch

trx_sys_t::find_same_or_older_low(): Move the unlikely and bulky
part of trx_sys_t::find_same_or_older() to a non-inline function.
trx_sys_t::find_same_or_older_in_purge(): A variant of
trx_sys_t::find_same_or_older() for use in the purge subsystem,
with potential concurrent access of the same trx_t object from
multiple threads.
trx_t::max_inactive_id_atomic: An Atomic_relaxed alias of the
regular data field trx_t::max_inactive_id, which we
use on systems that have native 64-bit loads or stores.
On any 64-bit system that seems to be supported by GCC, Clang or MSVC,
relaxed atomic loads and stores use the regular load and store
instructions. On -march=i686 the 64-bit atomic loads and stores
would use an XMM register.
This fixes a regression that had been introduced in
commit b7b9f3ce82 (MDEV-34515).
There would be messages
[ERROR] InnoDB: tried to purge non-delete-marked record in index

Make galera_sr.GCF-572 behave the same with and without option
innodb-snapshot-isolation. It is sufficient to remove a SELECT
statement from a transaction to delay the creation of the read
view in innodb. Avoiding the detection of a write-write conflict
under innodb-snapshot-isolation.
Ignore snapshot isolation conflict during fragment removal, before
streaming transaction commits. This happens when a streaming
transaction creates a read view that precedes the INSERTion of
fragments into the streaming_log table. Fragments are INSERTed
using a different transaction. These fragment are then removed
as part of COMMIT of the streaming transaction. This fragment
removal operation could fail when the fragments were not part
the transaction's read view, thus violating snapshot isolation.
Item_char_typecast::val_str_generic() uses Item::str_value as a buffer.
Item::val_str_ascii() also used Item::str_value as a buffer.
As a result, str_value tried to copy to itself.
Fixing val_str_ascii() to use a local buffer instead of str_value.
Make sure that node_1 remains in primary view by increasing it's
weight. Add suppression on expected warnings because we kill

We periodically observe assertion failures in the mtr tests,
specifically in the /storage/innobase/row/row0ins.cc file,
following a WSREP error. The error message is: 'WSREP: record
locking is disabled in this thread, but the table being modified
is not mysql/wsrep_streaming_log: mysql/innodb_table_stats.'"
This issue seems to occur because, upon opening the table,
innodb_stats_auto_recalc may trigger, which Galera does not
anticipate. This commit should fix this bug.

Use more robust self-pipe to wake up poll() by writing to the pipe's write

Additionally, the shutdown code underwent light refactoring
for better readability and maintainability:
- Modified `break_connect_loop()` to no longer wait for the main thread,
aligning behavior with Windows (since 10.4).

- Innochecksum misinterprets the freed pages as active one.
This leads the user to think there are too many valid
pages exist.
- To avoid this confusion, innochecksum introduced one
more option --skip-freed-pages and -r to avoid the freed
pages while dumping or printing the summary of the tablespace.
- Innochecksum can safely assume the page is freed if
the respective extent doesn't belong to a segment and marked as
freed in XDES_BITMAP in extent descriptor page.
- Innochecksum shouldn't assume that zero-filled page as extent
descriptor page.

The existing default value 1000 is too big and could result in
"hanging" when failing to connect a remote server. Three tries in
total is a more sensible default.
The bug was that backup_file_op_fail() was using a static variable
initialized by arguments. This does not work as static variables
will only be initialized on the first call and not change for future
calls, even when the arguments changes.
Fixed by removing 'static'.
