25f4238231 Merge branch '1.2.1-binlog_router_trx' into release-1.4.2 2016-04-14 18:52:36 +03:00
bb94ffb9ea Added more information to duplicate event error message
The message now states the location where it was called from and the amount
of events received from the master. In addition to this, new logging was
added when unsafe events are sent to slaves when transaction safety is enabled.
2016-04-06 17:30:25 +03:00
51e60000dd Add duplicate event detection & logging.
When an event is sent to a slave, we store information about the
event and who sent it, so that we can detect if the same event is
sent twice. If a duplicate event is detected, we log information
about it.

34c3d2c230 MXS-627: Changed the default version string
The default version string is now `5.5.5-10.0.0 <MaxScale version>-maxscale`.
This fill fix Java connector issues related to version string processing.

d3da98b58f Merge branch 'MXS-544' into develop-MXS-544-merge 2016-03-03 21:39:39 +02:00
cb3213af63 server/include/poll.h renamed to server/include/maxscale/poll.h
Due to an include conflict between /usr/include/poll.h and
maxscale/server/include/poll.h the latter was moved to
maxscale/server/include/maxscale/poll.h.

Once 1.4 is out, all maxscale header files will be moved to that
same sub-directory. That will prevent include conflicts and also
make it easy to see which include files belong to maxscale and
which do not.

bf1a789376 Added configurable multistatement behavior
Whether all queries should be routed to the master after a multistatement
query is executed can now be controlled with the `strict_multi_stmt` option.

When the option is disabled queries executed after a multistatement query will
be routed normally.
2016-03-01 10:45:08 +02:00
ac007fa8f5 MXS-497: Multi-statement queries are always routed to the master
This will prevent the routing of queries that modify data to the slaves.

In the future a more intricate solution can done where all the statements
are parsed and the destination is resolved based on the actual contents.

c25ef2f72a Added missing 5.5.5- prefix to MaxScale MySQL version
The handshake was sending "MaxScale 1.3.0" as the server version which causes
some connectors to think that the version is not valid.
2016-02-18 18:03:21 +02:00
cd2af6ffef Cleaned up the code based on the code review
Added missing error condition checks and cleaned up code.
2016-02-16 13:06:25 +02:00
9306b9d68c Added detection of checksums split across two packets
The checksums should now be processed properly event if the event is in more than
one packet.
2016-02-16 13:06:25 +02:00
2b7e2d3043 Added checksum calculations for events larger than 2^24 bytes
The checksums are now properly calculated for large events that span multiple
SQL packets.
2016-02-16 13:06:25 +02:00
ae33df3cbc Large events are now processed in chuncks
The router->last_written is used to store the position where the last event was
written. The replication header is also stored in a separate structure in
the router which is used later when the last packet of a multi-packet event
arrives.

866e91c088 Changes to improve robustness of SSL processing, separate it so far as possible from protocols. Separate the detailed mechanism of authentication from the MySQL protocol with a view to making it into a module later. 2016-02-15 09:29:07 +00:00
971d1d5de2 Redesign logic of SSL connections to work with status in client DCB instead of in the protocol. This eases the way to moving SSL logic out of a specific protocol (currently MySQL) so as to be available across any protocol. Also, some simplification. 2016-02-03 08:54:55 +00:00
fc6f49fe8a Link against Connector-C.
Now, qc_mysqlembedded is linked against MySQL's embedded library,
and MaxScale itself against Connector-C.

So, in order to build MaxScale, Connector-C must be installed.
This has been tested with Connector-C 2.2.1.

The build variable MYSQLCLIENT_LIBRARIES is no longer used.
2016-02-01 15:43:05 +02:00
475dfb7288 Use common function for setting up MySQL connection.
Earlier the same (or almost the same) code was duplicated in
several places.

A conflicting declaration was also removed. There was no
implementation for that declaration.

which targeted temporary tables even if they haven't been created.

e9755ba2b6 Remove file from slave
The binlog file is now always opened when it is needed and closed
when we are finished with it. That will remove any potential
file concurrency issues between different threads dealing with
the same slave.

4f8340f5b2 Changed behaviour for a slave requesting master_log_pos beyond binlog file size
Slave request for a log_pos behind binlog file size may result in a
disconnection or replication error:

if binlog file is latest one slave get disconnected otherwise an error
message is returned and replication stops
