If a limit on the replication lag is configured, servers with unmeasured
replication lag should not be used. The code in question did use them even
when a limit was set as the value used for undefined lag was -1 which
always measured lower than the limit.
The charset sent in the handshake is now done with the following
priorities:
* First Master server
* Last Slave server
* First Running server or Down server whose charset is known
The change is that server in the Down state to which we've successfully
connected to can also be used as the charset source. This, in addition
with an "empty" default charset, helps avoid the use of the default latin1
charset unless absolutely necessary.
VM should have 8 cores to make build faster in GCloud.
To get rid of ssfs between build hosts the build step
and upgrade test step are separated as well as
repository discriåtion generation

Lemon (the sqlite parser generator) destructors are needed for
all rules that return dynamically allocated structures. Otherwise
there may be leaks if a statement is not completely parsed.
By logging the password hash when user authentication fails due to a
password mismatch, we can be certain what the client sent and what is the
currently stored value in MaxScale. This should not be on by default which
is why a new parameter is required.
With this change, both 'SET @my_id = (SELECT LAST_INSERT_ID())' and
'SET @my_id = (SELECT @@LAST_INSERT_ID)' are classified as
QUERY_TYPE_MASTER_READ|QUERY_TYPE_SESSION_WRITE|QUERY_TYPE_USERVAR_WRITE
Earlier @@last_insert_id had the QUERY_TYPE_READ bit set as well, which
indirectly caused the problems of MXS-2898.
DIV and MOD are now also accepted instead of / and % respectively.
MOD is a keyword but (in principle incorrectly) decays into an id
when used in some other context. That is so that it will be
parser by the general function rule ("id ( ... )"). If used
incorrectly, the server will later reject.
It appears that the function db_my_assert may be used but not
built into the library.
With 10.4.12 there seem to occasionally be superfluous empty
table names.
