If the provided config path refers to a directory it can still
be opened and an attempt to read be made. However, as reading
will fail but end-of-file not be reached, we can't rely upon
'feof()' for detecting when to bail out.
As it is a user error to provide a directory as the config path,
that will be detected and deemed an error in a subsequent commit.
Stop replicating from master if unsupported binlog events are seen.
Also report error message for unsupported events
(blr_read_events_all_events) at maxscale start-up and with
maxbinlogcheck utility
If the gtid_domain_pos of the master is ever modified,
gtid-variables will have multiple domains. Generally, we are
only interested in the most recent domain. This is tracked in
gtid_domain_id:s and the value of the master is used for
filtering the correct domain from all gtid-values.
Also, use gtid_current_pos instead of gtid_slave_pos. The
advantage of current_pos is that the same variable works also
for master servers. The gtid-handling is now more thorough and
detects some weird situations.
The usage of the router_options has become optional in 2.1. This means
that the binlogrouter should not fail to start if no router_options are
defined.
Also lowered the error about master.ini to a warning as it is expected to
happen on a fresh installation.
MXS-1530: check ANNOTATE_ROWS flag in connecting slave.
In MariaDB 10.2.4 replicate_annotate_row_events and
binlog_annotate_row_events have default to ON: this change checks
whether the connecting slave is not has ANNOTATE_ROWS in
blr_slave_binlog_dump(), those ANNOTATE_ROWS events can be sent or not
to the slave.
If given a readily selected master server, Switchover will use it
as the new master. If the given server is invalid, nothing will
happen and an error is returned.
The internal header directory conflicted with in-source builds causing a
build failure. This is fixed by renaming the internal header directory to
something other than maxscale.
The renaming pointed out a few problems in a couple of source files that
appeared to include internal headers when the headers were in fact public
headers.
Fixed maxctrl in-source builds by making the copying of the sources
optional.
The utility and mock classes created for the testing of dbfwfilter
will be used for testing certain aspects of the cache filter.
Consequently better to move them somewhere outside dbfwfilter.
Sofar they will be built separately for each filter.
In 2.2 it is no longer possible to know where a particular column
appears. Hence the result when a column appears amongst the selected
columns and the where-clause must be the same.
