Temporary disable WSREP while executing RESET MASTER. In situation when 2 nodes are both master/slave first stop slave on both and than reset master. Enforce stricter causality check with wsrep_sync_wait.

Optimized the code that removed multiple equalities pushed from HAVING into WHERE. Now this removal is postponed until all multiple equalities are eliminated in substitute_for_best_equal_field().

When sampling data through ANALYZE TABLE, use the estimator to get a better estimation of avg_frequency instead of just using the raw sampled data.
-
Vicențiu Ciorbaru authored
The variable controls the amount of sampling analyze table performs. If ANALYZE table with histogram collection is too slow, one can reduce the time taken by setting analyze_sample_percentage to a lower value of the total number of rows. Setting it to 0 will use a formula to compute how many rows to sample: The number of rows collected is capped to a minimum of 50000 and increases logarithmically with a coffecient of 4096. The coffecient is chosen so that we expect an error of less than 3% in our estimations according to the paper: "Random Sampling for Histogram Construction: How much is enough?” – Surajit Chaudhuri, Rajeev Motwani, Vivek Narasayya, ACM SIGMOD, 1998. The drawback of sampling is that avg_frequency number is computed imprecisely and will yeild a smaller number than the real one.

The add method does not need to provide the row order number. It was only used to detect if the minimum/maximum value was populated once or not, so as to force an update for the first encounter of a value.

Remove CMake INSTALL command for COMPONENT DataFiles. mysql_install_db.exe will calculate default datadir, so that it can be called without any parameters.

The check for streaming replication logging format in THD::decide_logging_format() did the check also for DDLs running in TOI mode. This caused DROP DATABASE to fail if streaming replication was enabled. Added check for THD wsrep execution mode and perform the check only if the THD is in local processing mode (i.e. not TOI). Added galera_sr_create_drop test to verify that CREATE/DROP statements pass even if streaming replication is on.

in the tree bb-10.4-mdev7486 The crash was caused because of the similar problem as in mdev-16765: Item_cond::excl_dep_on_group_fields_for_having_pushdown() was missing.

It was allowed to push UDF functions and that caused a crash. To fix it it was forbidden to push UDF functions from HAVING into WHERE.

innobase_instant_try(): Assert that the column length of fixed-length columns is not changing.
-
Marko Mäkelä authored
If we instantly change the size of a fixed-length field and treat it as kind-of variable-length, then we will need conversions between old column values and new ones. I tried adding such a conversion to row_build(), but then I noticed that more conversions would be needed, because old values still appeared in a freshly rebuilt secondary index, causing a mismatch when trying to search with the correct longer value that was converted in my provisional fix to row_build(). So, we will revert the essential part of MDEV-15563: Instant ROW_FORMAT=REDUNDANT column extension (commit 22feb179), but not remove any tests.

Make sure that the Annotate_rows_log_events is written into binlog only for the first fragment of the current statement. Also avoid flusing pending rows event when calculating bytes generated by the transaction. Added and recorded a test which verifies that the binlog contains only one Annotate_rows_log_event per statement with various SR settings. Recrded mysql-wsrep-features#136 which produced different output with excession log events suppressed.

innobase_build_col_map_add(): Do not assume that old_field->pack_length() equals to field->pack_length(). Fix submitted by Aleksey Midenkov. innobase_instant_try(): Assert that the column length of fixed-length NOT NULL columns is only changing for ROW_FORMAT=REDUNDANT.

Followup: update test results

Change the defaults: -histogram_size=0 +histogram_size=254 -histogram_type=SINGLE_PREC_HB +histogram_type=DOUBLE_PREC_HB Adjust the testcases: - Some have ignorable changes in EXPLAIN outputs and more counter increments due to EITS table reads. - Testcases that meaningfully depend on the old defaults are changed to use the old values.

The Create_field::charset can contain garbage for columns that the SQL layer does not consider as being string columns. InnoDB considers BIT a string column for historical reasons (and backward compatibility with old persistent InnoDB metadata), and therefore it checked the charset. The Field::charset() consistently is my_charset_bin for BIT, so we can trust that one.

Fix clang warning: 'this' pointer cannot be null in well-defined C++ code; pointer may be assumed to always convert to true The only caller of TABLE::best_range_rowid_filter_for_partial_join() already seems to be assuming that s->table != NULL.

When node is JOINER and bin-log is enabled but bin-log-index is not set in configuration, we use NULL pointer which causes segfault. Fixed by checking for NULL pointer before using variable.

Condition can be pushed from the HAVING clause into the WHERE clause if it depends only on the fields that are used in the GROUP BY list or depends on the fields that are equal to grouping fields. Aggregate functions can't be pushed down. How the pushdown is performed on the example: SELECT t1.a,MAX(t1.b) FROM t1 GROUP BY t1.a HAVING (t1.a>2) AND (MAX(c)>12); => SELECT t1.a,MAX(t1.b) FROM t1 WHERE (t1.a>2) GROUP BY t1.a HAVING (MAX(c)>12); The implementation scheme: 1. Extract the most restrictive condition cond from the HAVING clause of the select that depends only on the fields that are used in the GROUP BY list of the select (directly or indirectly through equalities) 2. Save cond as a condition that can be pushed into the WHERE clause of the select 3. Remove cond from the HAVING clause if it is possible The optimization is implemented in the function st_select_lex::pushdown_from_having_into_where(). New test file having_cond_pushdown.test is created.

Galera versions below 4.x do not generate unique sequence number for view events. Take this into account when writing the SE checkpoint to avoid debug assertion in InnoDB.

Field_str::is_equal(): Do not allow instant conversions between BIT (which is stored big-endian) and integer types (which can be stored big-endian or little-endian, depending on storage engine). row_sel_field_store_in_mysql_format_func(): Properly extend narrower integer and DATA_FIXBINARY values to the current format. DATA_FIXBINARY was incorrectly padded with 0x20 instead of 0.

In tests that directly write InnoDB data file pages, compute the innodb_checksum_algorithm=crc32 checksums, instead of writing the 0xdeadbeef value used by innodb_checksum_algorithm=none. In this way, these tests will not cause failures when executing ./mtr --mysqld=--loose-innodb-checksum-algorithm=strict_crc32
