First commit to mysql-5.0 tree to include MySQL Federated Storage Handler.... 

First commit to mysql-5.0 tree to include MySQL Federated Storage Handler. This includes both the source and header files, test (results, test, require), and modifications to server and handler base files, and autoconf modifications to properly build federated handler.


configure.in:
  inclusion of federated handler autoheader macro
mysql-test/mysql-test-run.sh:
  allow usage of replication tests for federated handler
sql/Makefile.am:
  inclusion of federated header and source file
sql/field.h:
  overloaded method val_str() to work with fields in 'old_data' in 'update_row()'
sql/handler.cc:
  added code to include federated handler
sql/handler.h:
  add db type for federated
sql/mysql_priv.h:
  added code for federated handler
sql/mysqld.cc:
  added code for federated handler
sql/set_var.cc:
  added code for federated handler

1 MySQL supports a number of column types in several categories: numeric types, date and time types, and string (character) types. This chapter first gives an overview of these column types, and then provides a more detailed description of the properties of the types in each category, and a summary of the column type storage requirements. The overview is intentionally brief. The more detailed descriptions should be consulted for additional information about particular column types, such as the allowable formats in which you can specify values.
2 All arithmetic is done using signed BIGINT or DOUBLE values, so you should not use unsigned big integers larger than 9223372036854775807 (63 bits) except with bit functions! If you do that, some of the last digits in the result may be wrong because of rounding errors when converting a BIGINT value to a DOUBLE.
3 A floating-point number. p represents the precision. It can be from 0 to 24 for a single-precision floating-point number and from 25 to 53 for a double-precision floating-point number. These types are like the FLOAT and DOUBLE types described immediately following. FLOAT(p) has the same range as the corresponding FLOAT and DOUBLE types, but the display size and number of decimals are undefined.

MySQL Federated Storage Engine
ha_federated.cc - MySQL Federated Storage Engine
Patrick Galbraith and Brian Aker, 2004
This is a handler which uses a remote database as the data file, as
opposed to a handler like MyISAM, which uses .MYD files locally.
How this handler works
----------------------------------
Normal database files are local and as such: You create a table called
'users', a file such as 'users.MYD' is created. A handler reads, inserts,
deletes, updates data in this file. The data is stored in particular format,
so to read, that data has to be parsed into fields, to write, fields have to
be stored in this format to write to this data file.
With MySQL Federated storage engine, there will be no local files for each
table's data (such as .MYD). A remote database will store the data that would
normally be in this file. This will necessitate the use of MySQL client API
to read, delete, update, insert this data. The data will have to be retrieve
via an SQL call "SELECT * FROM users". Then, to read this data, it will have
to be retrieved via mysql_fetch_row one row at a time, then converted from
the column in this select into the format that the handler expects.
The create table will simply create the .frm file, and within the
"CREATE TABLE" SQL, there SHALL be any of the following :
comment=username:password@hostname:port/database/tablename
comment=username@hostname/database/tablename
comment=username:password@hostname/database/tablename
comment=username:password@hostname/database/tablename
This string is necessary for the handler to be able to connect to the remote
server.
The basic flow is this:
SQL calls issues locally ->
mysql handler API (data in handler format) ->
mysql client API (data converted to SQL calls) ->
remote database -> mysql client API ->
convert result sets (if any) to handler format ->
handler API -> results or rows affected to local
What this handler does and doesn't support
------------------------------------------
* There will not be support for transactions
* There is no way for the handler to know if the database on the remote end
has changed. The reason for this is that this database has to work like a
data file that would never be written to by anything other than the
database. The integrity of the data in the local table could be breached
if there was any change to the remote database.
* Support for SELECT, INSERT, UPDATE , DELETE, indexes
* No ALTER TABLE, DROP TABLE or any other Data Definition Language calls.
* Prepared statements will not be used in the first implementation, it
remains to to be seen whether the limited subset of the client API for the
server supports this
* This uses SELECT, INSERT, UPDATE, DELETE and not HANDLER for its
implementation
* Tables must be created on the remote server prior to any action on those
tables via the handler, first version.
* This will not work with the query cache
Method calls

How do I use this handler?
--------------------------
First of all, you need to build this storage engine:
./configure --with-federated-storage-engine
make
Next, to use this handler, it's very simple. You must
have two databases running, either both on the same host, or
on different hosts.
One the server that will be connecting to the remote
host (client), you create your table as such:
CREATE TABLE test_table (
id int(20) NOT NULL auto_increment,
name varchar(32) NOT NULL default '',
other int(20) NOT NULL default '0',
PRIMARY KEY (id),
KEY name (name),
KEY other_key (other))
ENGINE="FEDERATED"
DEFAULT CHARSET=latin1
COMMENT='root@127.0.0.1:9306/federated/test_federated';
Notice the "COMMENT" and "ENGINE" field? This is where you
respectively set the engine type, "FEDERATED" and remote
host information, this being the database your 'client' database
will connect to and use as the "data file". Obviously, the remote
database is running on port 9306, so you want to start up your other
database so that it is indeed on port 9306, and your federated
database on a port other than that. In my setup, I use port 5554
for federated, and port 5555 for the remote.
Then, on the remote database:
CREATE TABLE test_table (
id int(20) NOT NULL auto_increment,
name varchar(32) NOT NULL default '',
other int(20) NOT NULL default '0',
PRIMARY KEY (id),
KEY name (name),
KEY other_key (other))
ENGINE="<NAME>" <-- whatever you want, or not specify
DEFAULT CHARSET=latin1 ;
This table is exactly the same (and must be exactly the same),
except that it is not using the federated handler and does
not need the URL.
How to see the handler in action
--------------------------------
When developing this handler, I compiled the federated database with
debugging:
./configure --with-federated-storage-engine
--prefix=/home/mysql/mysql-build/federated/ --with-debug
Once compiled, I did a 'make install' (not for the purpose of installing
the binary, but to install all the files the binary expects to see in the
diretory I specified in the build with --prefix,
"/home/mysql/mysql-build/federated".
Then, I started the remote server:
/usr/local/mysql/bin/mysqld_safe
--user=mysql --log=/tmp/mysqld.5555.log -P 5555
Then, I went back to the directory containing the newly compiled mysqld,
<builddir>/sql/, started up gdb:
gdb ./mysqld
Then, withn the (gdb) prompt:
(gdb) run --gdb --port=5554 --socket=/tmp/mysqld.5554 --skip-innodb --debug
Next, I open several windows for each:
1. Tail the debug trace: tail -f /tmp/mysqld.trace|grep ha_fed
2. Tail the SQL calls to the remote database: tail -f /tmp/mysqld.5555.log
3. A window with a client open to the federated server on port 5554
4. A window with a client open to the federated server on port 5555
I would create a table on the client to the remote server on port
5555, and then to the federated server on port 5554. At this point,
I would run whatever queries I wanted to on the federated server,
just always remembering that whatever changes I wanted to make on
the table, or if I created new tables, that I would have to do that
on the remote server.
Another thing to look for is 'show variables' to show you that you have
support for federated handler support:
show variables like '%federat%'
and:
show storage engines;
Both should display the federated storage handler.
Testing
-------
There is a test for MySQL Federated Storage Handler in ./mysql-test/t,
federatedd.test It starts both a slave and master database using
the same setup that the replication tests use, with the exception that
it turns off replication, and sets replication to ignore the test tables.
After ensuring that you actually do have support for the federated storage
handler, numerous queries/inserts/updates/deletes are run, many derived
from the MyISAM tests, plus som other tests which were meant to reveal
any issues that would be most likely to affect this handler. All tests
should work! ;)
To run these tests, go into ./mysql-test (based in the directory you
built the server in)
./mysql-test-run federatedd
To run the test, or if you want to run the test and have debug info:
./mysql-test-run --debug federated
This will run the test in debug mode, and you can view the trace and
log files in the ./mysql-test/var/log directory
ls -l mysql-test/var/log/

Of course, again, you can tail the trace log:
tail -f mysql-test/var/log/master.trace |grep ha_fed
As well as the slave query log:
tail -f mysql-test/var/log/slave.log

The idea with handler::store_lock() is the following:
The statement decided which locks we should need for the table
for updates/deletes/inserts we get WRITE locks, for SELECT... we get
read locks.
Before adding the lock into the table lock handler (see thr_lock.c)
mysqld calls store lock with the requested locks. Store lock can now
modify a write lock to a read lock (or some other lock), ignore the
lock (if we don't want to use MySQL table locks at all) or add locks
for many tables (like we do when we are using a MERGE handler).
Berkeley DB for federated changes all WRITE locks to TL_WRITE_ALLOW_WRITE
(which signals that we are doing WRITES, but we are still allowing other
reader's and writer's.
When releasing locks, store_lock() are also called. In this case one
usually doesn't have to do anything.
In some exceptional cases MySQL may send a request for a TL_IGNORE;
This means that we are requesting the same lock as last time and this
should also be ignored. (This may happen when someone does a flush
table when we have opened a part of the tables, in which case mysqld
closes and reopens the tables and tries to get the same locks at last
time). In the future we will probably try to remove this.
Called from lock.cc by get_lock_data().
