The code erroneously called sec_since_epoch() for dates with zeros,
e.g. '2024-00-01'.
Fixi: adding a test that the date does not have zeros before
calling TIME_to_native().
The code in my_strtoll10_mb2 and my_strtoll10_utf32
could hit undefinite behavior by negation of LONGLONG_MIN.
Fixing to avoid this.
Also, fixing my_strtoll10() in the same style.
The previous reduction produced a redundant warning on
CAST(_latin1'-9223372036854775808' AS SIGNED)
The code in my_strntoull_8bit() and my_strntoull_mb2_or_mb4()
could hit undefinite behavior by negating of LONGLONG_MIN.
Fixing the code to avoid this.
This commit adds support for legacy names for files such
as mariadb_backup_galera_info, mariadb_backup_checkpoints
and mariabackup_binlog_info to allow upgrading from old
to new server versions without stopping the galera cluster.
Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
Added ability to disable/enable (--disable_cursor_protocol/
--enable_cursor_protocol) cursor-protocol in tests. If
"--disable_cursor_protocol" is used then ps-protocol is also
disabled. With cursor-protocol prepare statement is executed
only once. For "--cursor-protocol" added filter for queries:
it is executed only for "SELECT" queries.
The loose regex for the MDEV-34539 test ended up
matching the opensuse in the path in buildbot.
Adjust to more complete regex including space,
backtick and \n, which becomes much less common
as a path name.

The failing test case validates Seconds_Behind_Master for a delayed
slave, while STOP SLAVE is executed during a delay. The test fixes
initially added to the test (commit b04c857596) added a table lock
to ensure a transaction could not finish before validating the
Seconds_Behind_Master field after SLAVE START, but did not address a
possibility that the transaction could finish before running the
STOP SLAVE command, which invalidates the validations for the rest
of the test case. Specifically, this would result in 1) a timeout in
“Waiting for table metadata lock” on the replica, which expects the
transaction to retry after slave restart and hit a lock conflict on
the locked tables (added in b04c857596), and 2) that
Seconds_Behind_Master should have increased, but did not.
The failure can be reproduced by synchronizing the slave to the master
before the MDEV-32265 echo statement (i.e. before the SLAVE STOP).
This patch fixes the test by adding a mechanism to use DEBUG_SYNC to
synchronize a MASTER_DELAY, rather than continually increase the
duration of the delay each time the test fails on buildbot. This is
to ensure that on slow machines, a delay does not pass before the
test gets a chance to validate results. Additionally, it decreases
overall test time because the test can continue immediately after
validation, thereby bypassing the remainder of a full delay for each
transaction.
A CHAR column cannot be longer than 1024, because
Binlog_type_info_fixed_string::Binlog_type_info_fixed_string
replies on this fact - it cannot store binlog metadata for longer columns.
In case of the filename character set mbmaxlen is equal to 5,
so only 1024/5=204 characters can fit into the 1024 limit.
- In strict mode:
Disallowing creation of a CHAR column with octet length grater than 1024.
- In non-strict mode:
Automatically convert CHAR with octet length>1024 into VARCHAR.
The lsof utility is prone to blocking on system calls that
it uses to obtain information about sockets (or files, devices,
etc.). This behavior is described in its own documentation.
It has a '-b' option (in combination with warnings suppression
via '-w') that reduces the probability of blocking, introducing
new problems (luckily probably not relevant for our use case).
However, there is no guarantee that it will not hang on some
distributions, with some TCP/IP stack implementations, or with
some filesystems, etc. Also, of the three utilities that are
suitable for our purposes, lsof is the slowest. So if there
are other utilities that we use during SST, such as 'ss' or
'sockstat', it is reasonable to use them instead of lsof.
This commit changes the prioritization of utilities, it does
not need additional tests (besides the numerous SST tests
already available in the galera suites). If the system still
need to use lsof, this commit adds the '-b' and '-w' options
to it command line - to reduce the likelihood of blocking.
Removed handling of the long-unsupported xtrabackup_pid file,
as it is not even created by modern versions of mariabackup.
Instead, added stopping of the asynchronous process that
mariabackup runs (if it is still active) to the exception
handler.
This commit makes the SST script for mariabackup more
resilient to unexpected terminations or hangs while
mariabackup or when SST scripts in a previous session
are still running (in reality they were hung while
waiting for something).
GCC 12.2.0 could issue -Wnonnull for an unreachable call to
strlen(new_path). Let us prevent that by replacing the condition
(type == FILE_RENAME) with the equivalent (new_path).
This should also optimize the generated code, because the life time
of the parameter "type" will be reduced.
log_t::resize_write_buf(): If d<0 and d>-length, d will fit in ssize_t,
which is a signed 32-bit or 64-bit integer. Cast from int64_t to ssize_t
to make this clear and to silence a compiler warning.
my_b_encr_write(): Initialize also block_length, and at the same time
last_block_length, so that all 128 bits can be initialized with fewer
writes. This fixes an error that was caught in the test
encryption.tempfiles_encrypted.
test_my_safe_print_str(): Skip a test that would attempt to
display uninitialized data in the test unit.stacktrace.
Previously, our CI did not build unit tests with MemorySanitizer.
handle_delayed_insert(): Remove a redundant call to pthread_exit(0),
which would for some reason cause MemorySanitizer in clang-19 to
report a stack overflow in a RelWithDebInfo build. This fixes a
failure of several tests.

buf_page_t::read_complete(): Fix an incorrect condition that had been
added in commit aaef2e1d8c (MDEV-27058).
Also for compressed-only pages we must remember that buffered changes
may exist.
buf_read_page(): Correct the function comment; this is for a synchronous
and not asynchronous read. Pass the parameter unzip=true to
buf_read_page_low(), because each of our callers will be interested in
the uncompressed page frame. This will cause the test
encryption.innodb-compressed-blob to emit more errors when the
correct keys for decrypting the clustered index root page are unavailable.

Add support for removing the Content-Type header to the S3 engine. This
is required for compatibility with some S3 providers.
This also adds a provider option to the S3 engine which will turn on
relevant compatibility options for specific providers.
This was required for getting MariaDB S3 engine to work with "Huawei
Cloud S3".
To get Huawei S3 storage to work on has set one of the following
S3 options:
s3_provider=Huawei
s3_ssl_no_verify=1
