When an UPDATE or DELETE was executed with a WHERE condition it would
crash the MariaDB server. This is because the code expects the WHERE
condition to have generated a query string but it hasn't.
Also updates the ODBC test results for current MariaDB version.
In commit 28325b0863
a compile-time option was introduced to disable the macros
DBUG_ENTER and DBUG_RETURN or DBUG_VOID_RETURN.
The parameter name WITH_DBUG_TRACE would hint that it also
covers DBUG_PRINT statements. Let us do that: WITH_DBUG_TRACE=OFF
shall disable DBUG_PRINT() as well.
A few InnoDB recovery tests used to check that some output from
DBUG_PRINT("ib_log", ...) is present. We can live without those checks.

For tests that do not allow the use of an additional connection,

This memory leak was introduced in
commit 2e814d4702 (MariaDB Server 10.2.2)
via mysql/mysql-server@ce0a1e85e2
(MySQL 5.7.5).
The fix for MDEV-29352 was pushed to 10.6+ but the code causing the
bug is old and the bug is unlikely to be a recent regression in 10.6.
So, we apply the fix also to older versions, 10.3-10.5.
The original commit message:
MDEV-29352 SIGSEGV's in strlen and unknown location on optimized builds at SHUTDOWN
When the UDF creation frails to write the newly created UDF into
the related system table, the UDF is still created in memory.
However, as it is now, the related DLL is unloaded in this case right
in the mysql_create_function. And failure happens when the UDF handle
is freed and tries to unload the respective DLL which is still unloaded.
The rpl_row_img_sequence test can fail on resource
constrained buildbot machines due to its high
space consumption. To reduce this footprint, the
test is split into three parts, one for each value
of the binlog_row_img variable.
when generating a query to send to a remote server, spider generates
new aliases for all tables in the query (at least in the group_by handler).
First it walks all the expressions and create a list of new table aliases
to use for each field. Then - in init_scan() - it actually generates the
query, taking for each field the next alias from the list.
It dives recursively into functions, for example, for func(f1) it'll
go in, will see the field f1 and append to the list the new name for
the table of f1. This works fine for non-aggregate functions and
for aggregate functions in the SELECT list. But aggregate functions
in the ORDER BY are always references to the select list, they never
need to be qualified with a table name. That is, even if there is a
field name as an argument of an aggregate function in the ORDER BY
it must not append a table alias to the list. Let's just skip
aggregate functions when analyzing ORDER BY for table aliases.

* MDEV-29426 Fix memory leak in CONNECT JSON/BSON
If information is being gathered on JSON/BSON tables we leak the heap
allocated to the table class. With this fix we close and cleanup
instead, just as we do for XML tables.
The reason why mysql/mysql-server@8020cfac20
split the files was some unit tests that never existed in the
MariaDB Server code base. The storage/innobase/unittest/ works just fine
with this file.
This is reverting part of 2e814d4702
which applied InnoDB changes from MySQL 5.7.9.
The futex system calls were introduced in Linux 2.6.0,
which was released in December 2003. It should be safe to assume
that the system calls are always available on the Linux kernels
that MariaDB Server 10.3 would run on.
Let us use the normal platform-specific preprocessor symbols
__linux__, __sun__, _AIX instead of some homebrew ones.
The preprocessor symbol UNIV_HPUX must have lost its meaning
by f6deb00a56 (note: the symbol
UNIV_HPUX10 is being checked for, but only UNIV_HPUX is defined).
log_phys_t::apply(): When parsing an INSERT_HEAP_DYNAMIC record,
allow ll==rlen to hold for the last part. A secondary index record
may inherit all preceding bytes from the infimum pseudo-record.
For INSERT_HEAP_REDUNDANT, some header bytes will always be present
because the header will never be copied from the page infimum.
We will tolerate ll==rlen also in that case to be consistent with
the parsing of INSERT_HEAP_DYNAMIC.

this test loads sql_errlog plugin. then in a second connection
it triggers an error, this locks the plugin in that thd.
then the plugin is uninstalled in the default connection.
but that doesn't unload the plugin, as it's still locked. it'll
auto-unload after the foo connection is closed. without an explicit
disconnect it is closed after mysqltest exits and the post-test check
might still see sql_errlog not fully unoaded.
check_audit_mask(mysql_global_audit_mask, event_class_mask) is tested in
mysql_audit_general_log() and then assert in mysql_audit_acquire_plugins()
verifies that the condition still holds.
But this code path is not protected by LOCK_audit_mask, so
mysql_global_audit_mask can change its value between the if() and the
assert. That is, the assert is invalid and will fire if the
audit plugin is unloaded concurrently with mysql_audit_general_log().
Nothing bad will happen in this case though, we'll just do a useless
loop over all remaining installed audit plugins.
That is, the fix is simply to remove the assert.
- Commit c8948b0d0d introduced `get_one_variable()` - updating missing argument.
- Remove caller setting of empty string in `rpl_filter`, since underlying functions will do the same
(commit 9584cbe7fc introduced).

The issue manifests due to a bug in mysql_routine_grant. This was a side
effect of e46eea8660 which fixed the problem of not giving appropriate error
message (ER_NONEXISTING_PROC_GRANT) when a routine grant existed due to role
inheritance.
When granting a routine privilege, it is possible to have a GRANT_NAME
entry already created from an inherited role, but with it's init_privs
set to 0.
In this case we must not create a *new* grant entry, but we must edit
this grant entry to set its init_privs.
Note that this case was already covered by MDEV-29458, however due to a
forgotten "flush privileges;" the actual code path never got hit.
Remove the flush privilege command as it was never intended to be there
in the first place.
There was an issue in updating in-memory role datastructures when
propagating role grants.
The issue is that changing a particular role's privilege (on any
privilege level, global, database, etc.)
was done such that it overwrote the entire set of bits for that
particular level of privileges.
For example:
grant select on *.* to r1 -> sets the access bits to r1 to select,
regardless of what bits were present for role r1 (inherited from any
other roles).
Before this fix, the rights of role r1 were propagated to any roles r1
was granted to, however the propagated rights did *not* include the
complete rights r1 inherited from its own grants.
For example:
grant r2 to r1;
grant select on *.* to r2;
grant insert on *.* to r1; # This command completely disregards the
# select privilege from r2.
In order to correct this, ensure that before rights are propagated
onwards, that the current's role rights have been updated from its
grants.
Additionally, the patch exposed a flaw in the DROP ROLE code.
When deleting a role we removed all its previous grants, but what
remained was the actual links of roles granted to the dropped role.
Having these links present when propagating grants meant that we would
have leftover ACL_xxx entries.
Ensure that the links are removed before propagating grants.
There was a bug in the ACL internal data structures GRANT_TABLE and
GRANT_COLUMN. The semantics are: GRANT_TABLE::init_cols and
GRANT_COLUMN::init_privs represent the bits that correspond to the
privilege bits stored in the physical tables. The other struct members
GRANT_TABLE::cols and GRANT_COLUMN::privs represent the actual access
bits, as they may be modified through role grants.
The error in logic was mixing the two fields and thus we ended up
storing the logical access bits in the physical tables, instead of the
physical (init_xxx) bits.
This caused subsequent DBUG_ASSERT failures when dropping the involved
roles.
xb_read_delta_metadata(): For ROW_FORMAT=COMPRESSED tables, initialize
the info.zip_size with the physical page size and let info.page_size
remain the logical page size, like xb_delta_open_matching_space()
