Part #3:
Two more cases within row_search_mvcc need to handle the CHECK_ABORTED_BY_USER
and process this as a DB_INTERRUPTED.
|
| |
|
|
|
|
|
|
|
|
|
| |
Part #2:
- row_search_mvcc() should return DB_INTERRUPTED when it got
- Move the sync point from innodb internals to
handler_rowid_filter_check() where other storage engines can use
it too
- Add a similar syncpoint for the ICP check.
- Add a bigger test and test coverage for Rowid Filter with MyISAM
- Add test coverage for killed-during-ICP-check scenario

handler_rowid_filter_check can return CHECK_ABORTED_BY_USER.
All the functions that call row_search_idx_cond_check handle the
CHECK_ABORTED_BY_USER return value. So return it rather than generating an
error.
This incorrect handling was introduced in MDEV-21794 (8d85715d507d).

We can simply use C++11 std::atomic for avoiding undefined behaviour
related to concurrent stores to a shared variable. On most if not all
ISAs, std::memory_order_relaxed loads and stores will not really
differ from non-atomic loads or stores.

In fts_optimize_remove_table(), InnoDB tries to access the
fts_optimize_wq after shutting down the fts optimize thread.
This issue caused by the commit a41d429765c7ddb528b9b438c68b25ff55d3bd55.
Fix should check for fts optimize thread shutdown state
before checking fts_optimize_wq.

ibuf_merge_or_delete_for_page(): Do not attempt to invoke
ibuf_delete_recs() on a page of the change buffer itself.
The caller could already be holding ibuf->index->lock,
and an attempt to acquire it in S mode would hang the release server
or cause an assertion failure in rw_lock_s_lock_func() in a debug
server.
This problem was reproducible on 1 out of 2 runs of the following:
./mtr --no-reorder \
innodb.innodb-page_compression_default \
innodb.innodb-page_compression_snappy \
innodb.innodb-page_compression_zip \

This bug happened when the HEAP temporary table used for the derived table
created for a derived handler of a remote engine of the federated type
became full and was converted to an Area table. For this conversion
the tmp_table_param parameter must be always taken from the select_unit
object created for the result of the derived table.

type: 255 meta: 4 (0004)
Analysis:
========
"mysqlbinlog -v" option will reconstruct row events and display them as
commented SQL statements. If this option is given twice, the output includes
comments to indicate column data types and some metadata.
`log_event_print_value` is the function reponsible for printing values and
their types. This function doesn't handle GEOMETRY type. Hence the above error
gets printed.
Fix:
===
Add support for GEOMETRY datatype.

The original code was correct. mysql_upgrade calls the mysql client to
talk with MariaDB. It doesn't call itself!

Passing a null pointer to a nonnull argument is not only undefined
behaviour, but it also grants the compiler the permission to optimize
away further checks whether the pointer is null. GCC -O2 at least
starting with version 8 may do that, potentially causing SIGSEGV.

Shifting a 16-bit type by 16 bits is undefined behaviour.
The result is at least 32 bits, so let us cast the shift operand
to a wider type before shifting.

For some reason, adding -fsanitize=undefined (cmake -DWITH_UBSAN=ON)
to the compilation flags will cause even more warnings to be emitted.
The warnings do look bogus, but the code can be simplified.

For some reason, adding -fsanitize=undefined (cmake -DWITH_UBSAN=ON)
to the compilation flags will cause even more warnings to be emitted.
The warning was a bogus one:
tests/mysql_client_test.c:8632:22: error: '%d' directive writing between
1 and 11 bytes into a region of size 9 [-Werror=format-overflow=]
8632 | sprintf(field, "c%d int", i);
| ^~
tests/mysql_client_test.c:8632:20: note: directive argument
in the range [-2147483648, 999]
The warning does not take into account that the lower bound of the
variable actually is 0. But, we can help the compiler and use an
unsigned variable.
