Not reproducible on 10.3.
Based elenst’s first test case I filed and fixed MDEV-17735.
Here is a simpler version of the second test case:

The second ALTER TABLE will corrupt the metadata, causing a crash in anything that reads the table:

|
If the two operations are merged into a single statement, then there is no crash:
ALTER TABLE t1 ADD COLUMN b BIT FIRST, ADD COLUMN v INT AS (i) VIRTUAL; |
The merged ALTER TABLE operation will require a table rebuild until MDEV-17468 will allow ALGORITHM=INSTANT.
Similarly, if the two ALTER TABLE statements are swapped with each other, then the ADD COLUMN b would require a table rebuild.
The corrupted metadata of the test case survives a server restart. The corruption involves swapping the fixed_len of the index fields corresponding to the stored columns b and i:
(gdb) p *index->fields@index.n_fields
|
$1 = {{col = 0x7fffa801dea8, name = {m_name = 0x7fffa801dfb4 "DB_ROW_ID"},
|
prefix_len = 0, fixed_len = 6}, {col = 0x7fffa801dec8, name = {
|
m_name = 0x7fffa801dfbe "DB_TRX_ID"}, prefix_len = 0, fixed_len = 6}, {
|
col = 0x7fffa801dee8, name = {m_name = 0x7fffa801dfc8 "DB_ROLL_PTR"},
|
prefix_len = 0, fixed_len = 7}, {col = 0x7fffa801de88, name = {
|
m_name = 0x7fffa801dfb2 "i"}, prefix_len = 0, fixed_len = 1}, {
|
col = 0x7fffa801de68, name = {m_name = 0x7fffa801dfb0 "b"},
|
prefix_len = 0, fixed_len = 4}}
|
This metadata is created based on what is stored in SYS_COLUMNS. InnoDB fails to adjust the metadata when loading a table definition.
The virtual column operation involves a hack that should be removed in MDEV-17468:
dict_table_remove_from_cache(m_prebuilt->table);
|
m_prebuilt->table = dict_table_open_on_name(
|
tb_name, TRUE, TRUE, DICT_ERR_IGNORE_NONE);
|
Here is a simpler test case that does not involve virtual columns, but merely restarting the server:
--source include/have_innodb.inc
|
CREATE TABLE t1 (i INT) ENGINE=InnoDB; |
INSERT INTO t1 SET i=1; |
ALTER TABLE t1 ADD COLUMN b BIT FIRST, ALGORITHM=INSTANT; |
--source include/restart_mysqld.inc
|
SELECT * FROM t1; |
DROP TABLE t1; |

Not reproducible on 10.3.
When the assertion fails, we have the following fields[] and instant.fields[]:
DB_ROW_ID,DB_TRX_ID,DB_ROLL_PTR,t,dt,ts,b
DB_ROW_ID,DB_TRX_ID,DB_ROLL_PTR,t,ts,dt,b
So, the assertion is catching the unexpected swap of the index fields for the columns dt and ts.
It is already wrong that a placeholder for the dropped column f was discarded. It was there after ts when dict_table_t::instant_column() returned for the statement
ALTER TABLE t1 ADD COLUMN b BIT, DROP COLUMN f, ADD COLUMN t TIME FIRST; |
but it is no longer present when dict_table_t::prepare_instant() is invoked for the crashing statement:
ALTER TABLE t1 ADD COLUMN ts2 TIMESTAMP; |
The problem is due to a bug in dict_index_t::clear_instant_alter(). Already in MDEV-11369 in 10.3, we would convert the table into the ‘canonical format’ when it becomes empty. That was no problem back then, because columns could only be added last in the table.
With MDEV-15562 in 10.4.0, we can instantly add and drop columns. We cannot normally convert tables to ‘canonical format’ if any columns were dropped or permuted, because other connections could hold query processing templates that would have to be adjusted simultaneously. We can only convert to ‘canonical format’ during ALTER TABLE, which is protected by an exclusive lock. And exactly this is failing. After the call to dict_index_t::clear_instant_alter() we have the following fields[]:
DB_ROW_ID,DB_TRX_ID,DB_ROLL_PTR,t,dt,ts,b
But, the table columns are t,ts,dt,b! The columns dt,ts are wrongly swapped here.
The fix should be to pass col_map to the dict_index_t::clear_instant_alter() call, and permute the columns back.
Actually, dict_index_t::clear_instant_alter() was attempting to sort the fields by invoking std::swap() inside a loop, but its sorting algorithm was incorrect. Invoking std::sort() outside the loop fixes the issue.

Doesn't fail on 10.3.
Note: It's an extremely bad test case, run with --repeat=N, N as big as possible (thousands). The test case is most likely not minimal, but reducing it further blindly is too time-consuming due to the low probability of the failure.

Couldn't reproduce on 10.3.
This is a tricky test case. First, the creation of FULLTEXT INDEX will cause a hidden FTS_DOC_ID column to be created. This will actually cause the DROP COLUMN f1 to rebuild the table. Here is a simpler and equivalent test case, which uses a single connection, and also minimizes the columns and rows. It is still not deterministic:
--source include/have_innodb.inc
|
CREATE TABLE t1 (f2 INT) ENGINE=InnoDB; |
INSERT INTO t1 SET f2=1; |
ALTER TABLE t1 ADD COLUMN f1 INT; |
DELETE FROM t1; |
ALTER TABLE t1 DROP f2; |
DROP TABLE t1; |
During the execution of DROP f2, the table was emptied (due to the purge of the preceding DELETE) and converted to the canonical format.
In the 10.3 version, two assertions in dict_index_t::instant_add_field() are more relaxed than in 10.4:
DBUG_ASSERT(instant.n_core_fields >= n_core_fields);
|
DBUG_ASSERT(instant.n_core_null_bytes >= n_core_null_bytes);
|
In 10.3, these two assertions were already part of MDEV-11369.
The 10.4 version uses == instead of >=. But, the problem is that in this case, we have instant.n_core_fields < n_core_fields, because purge executed in the middle of the ALTER TABLE execution, after instant was created.
I will have to study the code carefully to see what else might have to be adjusted. With the assertions replaced, the test does not fail.
Here is a variant of the test that should be compatible with MDEV-11369 in 10.3:
--source include/have_innodb.inc
|
CREATE TABLE t1 (f2 INT) ENGINE=InnoDB; |
INSERT INTO t1 SET f2=1; |
ALTER TABLE t1 ADD COLUMN f1 INT; |
DELETE FROM t1; |
ALTER TABLE t1 ADD COLUMN f3 INT; |
DROP TABLE t1; |
It does not crash in 10.3 nor in 10.4.
I created a deterministic test that crashes also with ADD COLUMN f3 instead of DROP f2:
--source include/have_innodb.inc
|
--source include/have_debug.inc
|
--source include/have_debug_sync.inc
|
|
|
SET @saved_frequency = @@GLOBAL.innodb_purge_rseg_truncate_frequency; |
SET GLOBAL innodb_purge_rseg_truncate_frequency = 1; |
|
|
CREATE TABLE t1 (f2 INT) ENGINE=InnoDB; |
INSERT INTO t1 SET f2=1; |
ALTER TABLE t1 ADD COLUMN f1 INT; |
|
|
connect (purge_control,localhost,root); |
START TRANSACTION WITH CONSISTENT SNAPSHOT; |
|
|
connection default; |
DELETE FROM t1; |
|
|
SET DEBUG_SYNC='innodb_commit_inplace_alter_table_enter SIGNAL go WAIT_FOR do'; |
send ALTER TABLE t1 ADD COLUMN f3 INT; |
|
|
connection purge_control; |
SET DEBUG_SYNC='now WAIT_FOR go'; |
COMMIT; |
--source include/wait_all_purged.inc
|
SET DEBUG_SYNC='now SIGNAL do'; |
disconnect purge_control;
|
|
|
connection default; |
reap;
|
SET DEBUG_SYNC=RESET; |
DROP TABLE t1; |
SET GLOBAL innodb_purge_rseg_truncate_frequency = @saved_frequency; |
Again, no crash in 10.3.
I filed MDEV-17813 for the instant.n_core_fields == n_core_fields assertion failure.
Note: I'm not sure whether it's related, so I filed it separately as MDEV-17820. It has a test case.

I have tried all MTR based tests (code shown above) against a
10.4 301bd62b2536f85a8ce418dcd5e705796d8c5763 2019-01-10 compiled with debug
and none of them failed.
Result of 2h RQG testing (~570 regular finished runs) with table_stress.yy and threads = 12.
13 asserts hit

RQG tests using conf/mariadb/instant_add.yy (often used in the asserts reported above)
|
were stopped after 1h because all passed.

new_index->n_uniq == index->n_uniq is apparently MDEV-17376
The rest should probably be filed as separate bugs, and this one can be closed then.
None of the asserts hit by my RQG runs on actual 10.4 were mentioned above.
https://jira.mariadb.org/browse/MDEV-18165
https://jira.mariadb.org/browse/MDEV-17376
https://jira.mariadb.org/browse/MDEV-17644
Now that the code is more stable (after various fixes), let us close this for now and file new bugs for new failures.
In a failure that I analyzed in more detail, 2 instant ADD COLUMN were executed since the table was rebuilt: to the end, and to the start of the table (which is allowed by
MDEV-15562). The error occurred when trying to read the very first row in ALGORITHM=COPY. A TIMESTAMP column was incorrectly declared inside InnoDB as having a length of only 1 byte.
