Once @strong{BitKeeper} is installed,

@code{bk clone bk://work.mysql.com:7000 mysql} - the initial download

may take a while, depending on the speed of your connection.

Once @strong{BitKeeper} is installed, if you want to clone 3.23 branch,

@code{bk clone bk://work.mysql.com:7000 mysql}, and

@code{bk clone bk://work.mysql.com:7001 mysql-4.0} for 4.0 branch

- the initial download

may take a while, depending on the speed of your connection. If you have the

most

recent beta version of @strong{BitKeeper}, replace @code{clone} with

@code{oclone}.

@item

You will need GNU autoconf/automake, libtool, and m4 to do the next stage.

If you get some strange error during the first stage, check that you really

sure you have a full test case for the bug that we can run.

@item

If you have gotten to the @code{make} stage and it does not compile,

@itemize @bullet

@item

Fixed bug in @code{BDB} tables when using index on multi-part key where a

key part may be @code{NULL}.

@item

Fixed @code{MAX()} optimization on sub-key for @code{BDB} tables.

@item

Fixed problem with 'garbage results' when using @code{BDB} tables and

@code{BLOB} or @code{TEXT} fields when joining many tables.

@item

@item

Creation of a table of type @code{MERGE} doesn't check if the underlying

tables are of compatible types.

@item

@strong{MySQL} can't yet handle @code{NaN}, @code{-Inf} and @code{Inf}

values in double. Using these will cause problems when trying to export

and import data. We should as a intermediate solution change @code{NaN} to

@code{NULL} (if possible) and @code{-Inf} and @code{Inf} to the

Minimum respective maximum possible @code{double} value.

@end itemize

The following are known bugs in earlier versions of @strong{MySQL}:

@item

Add a portable interface over @code{gethostbyaddr_r()} so that we can change

@code{ip_to_hostname()} to not block other threads while doing DNS lookups.

@item

Add @code{record_in_range()} method to @code{MERGE} tables to be

able to choose the right index when there is many to choose from. We should

also extend the info interface to get the key distribution for each index,

of @code{analyze} is run on all sub tables.
