MDEV-8134: The relay-log is not flushed after the slave-relay-log.999999 showed
Problem:
========
Auto purge of relaylogs stops when relay-log-file is
'slave-relay-log.999999' and slave_parallel_threads is enabled.
Analysis:
=========
The problem is that in Relay_log_info::inc_group_relay_log_pos() function,
when two log names are compared via strcmp() function, it gives correct
result, when log name sequence numbers are of same digits(6 digits), But
when the number goes to 7 digits, a 999999 compares greater than
1000000, which is wrong, hence the bug.
Fix:
====
Extract the numeric extension part of the file name, convert it into
unsigned long and compare.
Thanks to David Zhao for the contribution.

+# ==== Purpose ====

+#
+# ==== Implementation ====
+#
+# Steps:
+# 0 - In master-slave setup clear all the relay logs on the slave server.
+# 1 - Start the slave so that new relay logs starting from
+# 'slave-relay-bin.000001' are created.
+# 2 - Get the active relay-log file name by using SHOW SLAVE STATUS.
+# Shutdown the slave server.
+# 3 - Rename active relay log to '999997' in both 'relay-log.info' and
+# 'slave-relay-bin.index' files.
+# 4 - Restart the slave server by configuring 'slave_parallel_threads=1'
+# and 'max_relay_log_size=100K'.
+# 5 - Generate load on master such that few relay logs are generated on
+# slave. The relay log sequence number will change to 7 digits.
+# 6 - Sync slave with master to ensure that relay logs are applied on
+# slave. They should have been automatically purged.
+# 7 - Assert that there is no 'slave-relay-bin.999999' file in
+# 'relay-log.info'.

Sorry, for private question, but I did not know where to ask.
mariadb-10.3.27.
I changed in include/myisam.h:
#define MI_MAX_KEY_LENGTH 3072 /* Max length in bytes */
but, it did not help, still this ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes.
What more to change to get key length 3072 for MyISAM tables?
And what can be negative impact of such a change?

Hi, Anel!
Sorry for that long delay with this review. Had real difficult weeks of my
life :(
Now it seems to be over, so getting back to normal.
Below is my opinions of the code i see in the branch
bb-10.1-anel-MDEV-13467-gis-feature-st_sphere-v2
Hope it's the recent version.
+ Adapter for functions that takes two or three arguments.
+*/
+
+class Create_func_arg2_or_3 : public Create_func
+{
Do you think we need the separate Create_fund_arg2_or_3 class?
If you don't see any other class to inherit from it,
i'd recommend to leave the Create_func_distance_sphere alone.
No need to have two constructors in the Item_func_sphere_distance
too. Just use the list argument as it's done for the
Item_func_json_contains (in 10.2).
Anyway i belive we should get rid of duplicating code
about the 'param1' and 'param2'. They can be popped/checked
with no if (arg_count == 2) condition.
+ double distance= 0.0;
+ null_value= (args[0]->null_value || args[1]->null_value);
+ if (null_value)
+ {
+ // Returned item must be set to Null
+ DBUG_ASSERT(maybe_null);
don't think it's needed.
+ return 0;
Should be return 0.0 i belive. Or goto handle_errors.
Thet goes to all but one 'return' statements in this function.
+ }
> ...
> if (!arg1 || !arg2)
This last condition should never happen since we have not-null_value.
So i'd remove that 'if' section completely.
And anyway it should do the 'return' in that branch.
+ null_value= args[2]->null_value;
+ if (null_value)
+ {
+ return 0;
+ }
seems nicer to me this way
if (args[2]->null_value)
{
null_value= true;
goto handle_errors;
}
+ if (!(g1= Geometry::construct(&buffer1, arg1->ptr(), arg1->length())) ||
+ !(g2= Geometry::construct(&buffer2, arg2->ptr(), arg2->length())))
+ {
+ goto handle_errors;
we should launch the ER_GIS_INVALID_DATA here.
+ // Generate error message in case different geometry is used?
Yes, i think the explainig message here is good to have.
+double Item_func_sphere_distance::spherical_distance(Geometry *g1,
+ Geometry *g2,
+ const double
sphere_radius)
+double Item_func_sphere_distance::spherical_distance_points(Geometry *g1,
+ Geometry *g2,
+ const double r)
Why these two are member static functions, not simply static?
If you plan any 'external' use for them, please add comments about
what exacly they do.
+double Item_func_sphere_distance::spherical_distance(Geometry *g1,
+ Geometry *g2,
+ const double
sphere_radius)
+{
+ double res= 0.0;
+ switch (g1->get_class_info()->m_type_id)
+ {
+ case Geometry::wkb_point:
+ res= spherical_distance_points(g1, g2, sphere_radius);
+ break;
+
+ case Geometry::wkb_multipoint:
+ res= spherical_distance_points(g1, g2, sphere_radius);
+ break;
Why do we need this function?
We confirmed already that the type is either wkb_point or wkb_multipolygon,
so just can call spherical_distance_points. No?
>>>>>
+class Item_func_sphere_distance: public Item_real_func
+{
+ double sphere_radius= 6370986.0; // Default radius equals Earth radius
Some compilers don't like this syntax, and we didn't use it yet, so
i'd recomment to move this to the constructor or even better to the
::val_real().
+double Gis_point::calculate_haversine(const Geometry *g,
+ const double sphere_radius)
+{
+ DBUG_ASSERT(sphere_radius > 0);
+ double x1r= 0.0;
+ double x2r= 0.0;
+ double y1r= 0.0;
+ double y2r= 0.0;
That lot of unnecessary initializations seems excessive.
+ if (g->get_class_info()->m_type_id == Geometry::wkb_multipoint)
+ {
+ const char point_size= 4 + WKB_HEADER_SIZE + POINT_DATA_SIZE+1; //1
for the type
+ char point_temp[point_size];
+ memset(point_temp+4, Geometry::wkb_point, 1);
+ memcpy(point_temp+5, static_cast<const Gis_multi_point
*>(g)->get_data_ptr()+5, 4);
+ memcpy(point_temp+4+WKB_HEADER_SIZE,
g->get_data_ptr()+4+WKB_HEADER_SIZE,
+ POINT_DATA_SIZE);
+ point_temp[point_size-1]= '\0';
+ Geometry_buffer gbuff;
+ Geometry *gg= Geometry::construct(&gbuff, point_temp, point_size-1);
There is the Gis_multi_point::geometry_n() function, should be used here to
get the point.
I don't like that lot of static_cast-s.
Isn't it nicer to have just the function of
double calculate_harvesine_points(Geometry *p1, Geometry *p2, double radius)
double calculate_harvesine_multipoint_point(Geometry *mp, Geometry *p,
double radius)
double calculate_harvesine_multipoint_multipoint(Geometry *mp1, Geometry
*mp2, double radius)
which would call each other?
The ::get_xy_radian() method looks unneeded to me.
It's enough to have the to_radian(double d) function.
BTW it's possible to do the multipoint/multipoint calculations faster than
n^2.
Not necessary to do it right now, just not to remember.
Best regards.

MDEV-23033: All slaves crash once in ~24 hours and loop restart with signal 11
Problem:
=======
Upon deleting or updating a row in a parent table (with primary key), if
the child table has virtual column and an associated key with ON UPDATE
CASCADE/ON DELETE CASCADE, it will result in slave crash.
Analysis:
========
Tables which are related through foreign key require prelocking similar to
triggers. i.e If a table has triggers/foreign keys we should add all tables
and routines used by them to the prelocking set. This prelocking happens
during 'open_and_lock_tables' call. Each table being opened is checked for
foreign key references. If foreign key reference exists then the child
table is opened and it is linked to the table_list. Upon any modification
to parent table its corresponding child tables are retried from table_list
and they are updated accordingly. This prelocking work fine on master.
On slave prelocking works for following cases.
- Statement/mixed based replication
- In row based replication when trigger execution is enabled through
'slave_run_triggers_for_rbr=YES/LOGGING/ENFORCE'
Otherwise it results in an assert/crash, as the parent table will not find
the corresponding child table and it will be NULL. Dereferencing NULL
pointer leads to slave server exit.
Fix:
===
Introduce a new 'slave_fk_event_map' flag similar to 'trg_event_map'. This
flag will ensure that when foreign key is enabled in row based replication
all the parent and child tables are prelocked, so that parent is able to
locate the child table.
Note: This issue is specific to slave, hence only slave needs to be
upgraded.

+# ==== Purpose ====
+#
+# Test verifies that, slave doesn't report any assert on UPDATE or DELETE of
+# row which tries to update the virtual columns with associated KEYs.
+#
+# Test scenarios are listed below.
+# 1) KEY on a virtual column with ON DELETE CASCADE
+# 2) Verify "ON DELETE CASCADE" for parent->child->child scenario
+# 3) KEY on a virtual column with ON UPDATE CASCADE
+# 4) Define triggers on master, their results should be replicated
+# as part of row events and they should be applied on slave with
+# the default slave_run_triggers_for_rbr=NO
+# 5) Define triggers + Foreign Keys on master, their results should be
+# replicated as part of row events and master and slave should be in sync.
+# 6) Triggers are present only on slave and 'slave_run_triggers_for_rbr=NO'
+# 7) Triggers are present only on slave and 'slave_run_triggers_for_rbr=YES'
+# 8) Triggers and Foreign Keys are present only on slave and
+# 'slave_run_triggers_for_rbr=NO'
+# 9) Triggers are Foreign Keys are present only on slave and
+# 'slave_run_triggers_for_rbr=YES'
