Changed getter function return values to std::string, converted
MXS_CONFIG_PARAMETER::set_from_list to take std::strings instead of const
char pointers.
SSLContext is now used everywhere except the binlogrouter which still
allocates the contexts itself. Fixing the binlogrouter's misuse of
internal structures is a rather large undertaking and for this reason the
SSLContext will be taken into use there in a separate commit.
Added core functionality for UNIX domain sockets in servers. Currently the
address parameter accepts them both but a separate `socket` parameter is
needed.
When debugging you occasionally want to find out what a packet
contains (e.g. delivered to clientReply). Manually looking into
the packet works, but is tedious. With this function you when
the execution has been stopped in GDB examine a protocol packet.
E.g.
Thread 3 "maxscale" hit Breakpoint 6, RWSplitSession::clientReply (this=0x7fffe401ed20, writebuf=0x7fffe401e910, backend_dcb=0x7fffe401dbe0) at /home/wikman/MariaDB/MaxScale/server/modules/routing/readwritesplit/rwsplitsession.cc:567
567 DCB* client_dcb = backend_dcb->session->client_dcb;
(gdb) p dbg_decode_response(writebuf)
$30 = 0x7ffff0d40d54 "Packet no: 1, Payload len: 44, Command : ERR, Code: 1146, Message : Table 'test.blahasdf' doesn't exist"
In progress, does not yet overwrite existing code.
The new promotion mechanism automatically retries queries which timed out. It also
handles multimaster situations correctly.
See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
With the flag --debug=enable-statement-logging it is now possible
to instruct MaxScale to log all SQL statements it sends to the
servers.
The format of the logged string looks like:
notice : SQL(127.0.0.1): 0, "SELECT ..."
First the fixed string "SQL", followed by the server address in
parenthesis followed by the actual return value of mysql_query(),
followed by the statement itself.
The "SQL" string makes the lines easy to grep for and having the
return value before the statement makes it easier to spot since
the length of the return value string does not wary much, but the
length of the statements do wary a lot.
* MXS-199: Support Causal Read in Read Write Splitting
* move most causal read logic into rwsplit router and get server type from monitor
* misc fix: remove new line
* refactor, move config to right place, replace ltrim with gwbuf_consume
* refacter a little for previous commit
* fix code style
The helper function provides map-like access to row values. This is used
to retrieve the values for all MariaDB 10.0+ versions as there are
differences in the returned results between 10.1 and 10.2.
That allows the version to be updated and read atomically. If
major/minor/patch are stored as separate variables, you can get an
inconsistent set. Now it may be out of date by the time it is used,
but it will never be internally inconsistent.
