Change the default authentication for root@localhost to
IDENTIFIED VIA mysql_native_password USING 'invalid' OR unix_socket
which provides secure passwordless login, while still allowing
SET PASSWORD to work as expected.
Also create a second all-privilege account for the user that owns
datadir (and thus has full access to the data anyway).
Compile unix_socket plugin statically into the server.
If wsrep_load_data_splitting is configured, change streaming replication
parameters internally to match the original behavior, i.e. replicate
on every 10000 rows. After load data is over, restore original
streaming replication settings.
Removed redundant wsrep_tc_log_commit().
Most of the mtr tests in the galera_3nodes suite fail
for a variety of reasons with a variety of errors.
This patch fixes several substantial flaws
in the galera_3nodes suite tests and in the mtr framework
service files, adapting the tests from galera_3nodes
for the current version of MariaDB.
This patch also synchronizes some galera_3nodes-related
files with the latest changes made for MDEV-17835 (v2 patch)
and for MDEV-18379 in other branches (10.2 and 10.3).
Closes#1161
When importing a tablespace, we must initialize dummy DEFAULT NULL
values for any instantly added columns in order to avoid a debug
assertion failure when PageConverter::update_records() invokes
rec_get_offsets(). Finally, when the operation completes, we must
evict and reload the table definition, so that the correct
default values for instantly added columns will be loaded.
ha_innobase::discard_or_import_tablespace(): On successful
IMPORT TABLESPACE, evict and reload the table definition,
so that btr_cur_instant_init() will load the correct metadata.
PageConverter::update_index_page(): Fill in dummy DEFAULT NULL values
for instantly added columns. These will be replaced upon the
completion of the operation by evicting and reloading the metadata.
row_discard_tablespace(): Invoke dict_table_t::remove_instant().
After DISCARD TABLESPACE, the table is no longer in "instant ALTER"
format, because there is no data file attached.
The code path where the table was not being rebuilt during ALTER TABLE
was not covered by the test. Add coverage, and remove the debug assertion
that could fail in this case.
The code was rewritten in the same way as the code of
ha_partition::multi_range_read_info_const() had been rewritten
earlier.
The fix allowed to run spider.partition_mrr.
Find indexes of one table which parts participate in one constraint.
These indexes are called constraint correlated.
New methods: TABLE::find_constraint_correlated_indexes() and
virtual method check_index_dependence() were added.
For each index it's own constraint correlated index map was created
where all indexes that are constraint correlated with the current are
marked.
The results of this task are used for MDEV-16188 (Use in-memory
PK filters built from range index scans).
This is only a placeholder that allows an implementation later
during the development of MariaDB, so that downgrade to an earlier
version (with this code) will be possible.
We want to be able to zero out freed pages to reduce write amplification,
and to scrub old data. Zeroing out the pages is optional, not mandatory
for correctness. After all, the MLOG_INIT_FREE_PAGE record can only be
emitted for pages that are marked free in the allocation bitmap page.
Use ibuf_bitmap_page_init() only during recovery.
fsp_fill_free_list(): Initialize the FIL_PAGE_TYPE using MLOG_2BYTES.
The page contents will already have been zeroed out by
MLOG_INIT_FILE_PAGE2.
ibuf_bitmap_init_apply(): Replaces ibuf_parse_bitmap_init().
* Donor node will now provide binlog-index argument to wsrep_sst_rsync script if binlog is used.
* Write correct path and binlog file names into joiner binlog-index file
During parallel execution mariabackup script can fail when trying to create archive because of non unique name. Extending archive timestamp with nanosecond.
