Generalized support for auto-updated and/or auto-initialized timestamp and datetime columns. This patch is a reimplementation of MySQL's "WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to ease future merges, this implementation reused few function and variable names from MySQL's patch, however the implementation is quite different. TODO: The only unresolved problem in this patch is the semantics of LOAD DATA for TIMESTAMP and DATETIME columns in the cases when there are missing or NULL columns. I couldn't fully comprehend the logic behind MySQL's behavior and its relationship with their own documentation, so I left the results to be more consistent with all other LOAD cases. The problematic test cases can be seen by running the test file function_defaults, and observing the test case differences. Those were left on purpose for discussion. |

This is the FederatedX Storage Engine, developed as an external storage engine. NOTE: The following is only relevant if you use it for MySQL. MariaDB already comes with the latest version of FederatedX. To install, grab a copy of the mysql source code and run this: ./configure --with-mysql=/path/to/src/mysql-5.x --libdir=/usr/local/lib/mysql/ make install And then inside of MySQL: mysql> INSTALL PLUGIN federatedx SONAME 'libfederatedx_engine.so'; mysql> CREATE TABLE `d` (`a` varchar(125), b text, primary key(a)) ENGINE=FEDERATEDX CONNECTION="mysql://root@host/schema/table" or mysql> CREATE TABLE `d` (`a` varchar(125), b text, primary key(a)) ENGINE=FEDERATEDX CONNECTION="server" CHARSET=latin1; You will probably need to edit the Makefile.am in the src/ tree if you want to build on anything other then Linux (and the Makefile assumes that the server was not compiled for debug). The reason for the two possible configure lines is that libdir is dependent on where MySQL was installed. If you run the "INSTALL PLUGIN ..." and you get a file not found, check that your configured this directory correctly. For Solaris you can enable DTrace probes by adding to configure --enable-dtrace
