Monty 7332af49e4 - Renaming variables so that they don't shadow others (After this patch one can compile with -Wshadow and get much fewer warnings)
- Changed ER(ER_...) to ER_THD(thd, ER_...) when thd was known or if there was many calls to current_thd in the same function.
- Changed ER(ER_..) to ER_THD_OR_DEFAULT(current_thd, ER...) in some places where current_thd is not necessary defined.
- Removing calls to current_thd when we have access to thd

Part of this is optimization (not calling current_thd when not needed),
but part is bug fixing for error condition when current_thd is not defined
(For example on startup and end of mysqld)

Notable renames done as otherwise a lot of functions would have to be changed:
- In JOIN structure renamed:
   examined_rows -> join_examined_rows
   record_count -> join_record_count
- In Field, renamed new_field() to make_new_field()

Other things:
- Added DBUG_ASSERT(thd == tmp_thd) in Item_singlerow_subselect() just to be safe.
- Removed old 'tab' prefix in JOIN_TAB::save_explain_data() and use members directly
- Added 'thd' as argument to a few functions to avoid calling current_thd.

TODO Added federatedx storage engine 2009-10-30 20:50:56 +02:00

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
