added alternative name for MariaDB-devel package to replace
mariadb-connector-c-devel from RHEL 8 distribution.
this patch is for 10.3+ on RHEL/Centos 8
SST scripts currently use Linux-specific construction
to create a temporary directory if the path prefix for
that directory is specified by the user. This does not
work with FreeBSD. This commit adds support for FreeBSD.
No separate test required.
btr_defragment_save_defrag_stats_if_needed(): Do not save
defragmentation statistics for temporary tables.
They are exempt of defragmentation anyway
(ha_innobase::optimize() never invokes defragmentation for them),
and the user-visible names are not available inside InnoDB.
Furthermore, InnoDB assumes that temporary tables are never accessed
by other threads than the one that handles the session with which
the temporary table is associated with.
Furthermore, we simplify the test innodb.innodb_defrag_stats
and include a test case that demonstrates that defragmentation
statistics are no longer being saved for temporary tables.
Problem was that there was extra condition !thd->lex->no_write_to_binlog
before call to begin TOI. It seems that this variable is not initialized.
TRUNCATE does not support [NO_WRITE_TO_BINLOG | LOCAL] keywords, thus
we should not check this condition. All this was hidden in a macro,
so I decided to remove those macros that were used only a few places
with actual function calls.
dict_index_t::clear_instant_alter(): when searhing for an AUTO_INCREMENT column
don't skip the beginning of the list because the field can be at the beginning of the list
instead of original name of the column
When doing refactoring of temporary table field creation a mistake was
done when copying the column name when creating internal temporary tables.
For internal temporary tables we should use the original field name, not
the item name (= alias).
Thanks to Fabian Vogt for noticing the mutual exclusions
of these open flags on tmpfs caused by mariadb opening it
incorrectly.
As such we clear the O_CREAT flag while opening it as O_TMPFILE.
Fix sporadic failure for MTR test galera_sr.GCF-1018B. The test
sometimes fails due to an error that is logged to the error log
unnecessarily.
A deterministic test case (included in this patch) shows that the
error is loggen when a transaction is BF aborted right before it
opens the streaming log table to perform fragment removal. When that
happens, the attempt to open the table fails and consequently an error
is logged. There is no need to log this error, as an ER_LOCK_DEADLOCK
error is returned to the client.

InnoDB could evict the fts auxiliary table in
row_fts_merge_insert(). So bulk insert could be
dealing with garbage FTS auxiliary table.Patch
should delay closing the table in row_fts_merge_insert().
A conversion warning 4267 that we want to disable(prior to 10.3),
was suppressed with cmake VS generator for C++ and C, despite being set
only for CXX flags.
The fix is to disable the warning in C flags, too. In 10.2, this warning
is noisy, in 10.3 it is fixed.
The st_blksize returned by fstat(2) is not documented to be
a power of 2, like we assumed in
commit 58252fff15 (MDEV-26040).
While on Linux, the st_blksize appears to report the file system
block size (which hopefully is not smaller than the sector size
of the underlying block device), on FreeBSD we observed
st_blksize values that might have been something similar to st_size.
Also IBM AIX was affected by this. A simple test case would
lead to a crash when using the minimum innodb_buffer_pool_size=5m
on both FreeBSD and AIX:
seq -f 'create table t%g engine=innodb select * from seq_1_to_200000;' \
1 100|mysql test&
seq -f 'create table u%g engine=innodb select * from seq_1_to_200000;' \
1 100|mysql test&
We will fix this by not trusting st_blksize at all, and assuming that
the smallest allowed write size (for O_DIRECT) is 4096 bytes. We hope
that no storage systems with larger block size exist. Anything larger
than 4096 bytes should be unlikely, given that it is the minimum
virtual memory page size of many contemporary processors.
MariaDB Server on Microsoft Windows was not affected by this.
While the 512-byte sector size of the venerable Seagate ST-225 is still
in widespread use, the minimum innodb_page_size is 4096 bytes, and
innodb_log_file_size can be set in integer multiples of 65536 bytes.
The only occasion where InnoDB uses smaller data file block sizes than
4096 bytes is with ROW_FORMAT=COMPRESSED tables with KEY_BLOCK_SIZE=1
or KEY_BLOCK_SIZE=2 (or innodb_page_size=4096). For such tables,
we will from now on preallocate space in integer multiples of 4096 bytes
and let regular writes extend the file by 1024, 2048, or 3072 bytes.
The view INFORMATION_SCHEMA.INNODB_SYS_TABLESPACES.FS_BLOCK_SIZE
should report the raw st_blksize.
For page_compressed tables, the function fil_space_get_block_size()
will map to 512 any st_blksize value that is larger than 4096.
os_file_set_size(): Assume that the file system block size is 4096 bytes,
and only support extending files to integer multiples of 4096 bytes.
fil_space_extend_must_retry(): Round down the preallocation size to
an integer multiple of 4096 bytes.
FTS indexes has a prefix_len=1 or prefix_len=0 as stated by comment in
mysql_prepare_create_table().
Thus, a newly added assertion should be relaxed for FTS indexes.
Bug happens when partially indexed CHAR or VARCHAR field in converted from
utf8mb3 to utf8mb4.
Fixing by relaxing assertions. For some time dict_index_t and dict_table_t
are becoming not synchronized. Namely, dict_index_t has a new prefix_len which
is a multiple of a user-provided length and charset->mbmaxlen. But
the table still have and old mbmaxlen and assertion fails. This happens only
during utf8mb3 -> utf8mb4 conversions and the magic number 4 comes from
utf8mb_4_.
At the end of ALTER TABLE (innobase_rename_or_enlarge_columns_cache())
dict_index_t and dict_table_t became synchronized
again and will stay so at all times. For, example, they will be synchronized
on table load and newly added assertion proves that.
Improve documentation of performance_schema tables by appending COLUMN
comments to tables. Additionally improve test coverage and update corresponding
tests.

Note: This is a backport of 1cb4caa66d from
10.3
Analysis: Assertion failure happens because less session memory is set and so
table can't be reopened. So the statement can't be used. This error goes
unreported.
Fix: Return the error state.
* Update wsrep-lib which contains the fix
* Add deterministic test case that reproduces the assertion
