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 aaef2e1d8c843d1e40b1ce0c5199c3abb3c5da28 (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.

buf_pool_t::page_fix(): If a change buffer merge may be needed on a
ROW_FORMAT=COMPRESSED page that exists in compressed-only format in
the buffer pool, go ahead to decompress the block. This fixes an
infinite loop.

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

The 10.5->10.6 merge commit 3bc98a4ec4e casts the arg to an int16
pointer in set_extraction_flag_processor(). This matched the previous
commit c76eabfb5e3 where set_extraction_flag was changed to have int16 arg
instead of int.
The commit a5e4c34991e for MDEV-29363 added a call to
set_extraction_flag_processor on IMMUTABLE_FL (MARKER_IMMUTABLE in 10.6).
The subsequent 10.5->10.6 merge f071b7620b2 did not cast the flag
to int16 when merging this change.
The result is big-endian processors cleared the immutable
flag rather than set the flag, resulting in MDEV-29363
being unfixed on big-endian processors.
10.5 added contents of cmake/os/FreeBSD.cmake in c991efd9c35eb3f2a90b2562071860a10a4cbaa2.
in the merge to 10.11, d002b1f removed this file.
In the past FreeBSD.cmake was removed in 5369df741b3a87d7b262aafe95438b33ed124295
in the 10.11 branch as no remaining code was needed. The combination
of this and the merge lead to the the file being removed. My assumption is
this was a non-stable branch at the time.
The purpose of this patch is clang doesn't have /usr/local/lib in
the path. As such there are various depedency linkages that will fail.
For example pcre and libfmt.
In mariadb-backup --backup there are multiple mechanisms for ensuring that
a sufficient amount of the InnoDB write-ahead log (ib_logfile0) is being
copied at the end of the backup. The backup needs to include the latest
committed transaction. While further transaction commits are blocked by
BACKUP STAGE BLOCK_COMMIT, ongoing transactions may modify the database
contents and write log records. We were unnecessarily copying such log,
which would also cause further effort of rolling back incomplete
transactions after the backup is restored.
backup_wait_for_lsn(): Declare as static, and refactor some code
to separate functions backup_wait_for_lsn_low() and
backup_wait_timeout().
backup_wait_for_commit_lsn(): A new function to determine the current
LSN (within BACKUP STAGE BLOCK_COMMIT) and to wait for the log to be
copied until that. Invoked by BackupStages::stage_block_commit().
xtrabackup_backup_func(): Remove a condition that had already been
checked by a caller of backup_wait_timeout().
server_lsn_after_lock: Declare as a local variable in
BackupStages::stage_block_ddl().
log_copying_thread(), io_watching_thread(): Use metadata_last_lsn
instead of metadata_to_lsn as the stop condition.
BackupStages::stage_block_commit(): Ensure that the log tables
(in particular, mysql.general_log) will have been copied before
the BACKUP STAGE BLOCK_COMMIT is being followed by any further
SQL statements.
