This patch contains fixes that make the SCI Transporter build. There was a number of
problems introduced in newer versions of MySQL that have been corrected in this
patch.

dolphin_build_adds.patch
This patch contains 2 new build scripts that can be used to build MySQL Cluster using the
SCI Transporter.

How to repeat:
Try to build NDB cluster with the SCI transporter, observe failures. Apply the patch and
repeat.

dolphin_build_adds.patch

Attachment: dolphin_build_adds.patch (text/x-patch), 2.36 KiB.

Discussed with Mikael/Tomas: Patches not yet ready, reverting to PP status and assigning
to Mikael for now.

The patch was pushed to 5.0.44 + 5.1.20

Noted that the new scripts are available in the 5.0.44 and 5.1.20 changelogs. However...
according to http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-sci-sockets.html,

"It is possible to use SCI Sockets with any version of MySQL Cluster. No special builds
are needed because it uses normal socket calls which are already available in MySQL
Cluster."

So why are special build scripts needed? Do the -max builds not include 
--with-ndb-sci=/opt/DIS as the statement in the Manual would seem to suggest?

Are there any other errors/inconsistencies on that page that need to be corrected?

Thanks!

There is a difference between using SCI Sockets and using SCI Transporter.
SCI Sockets uses TCP/IP sockets and can be used with any MySQL Cluster version.
However SCI Sockets (SuperSockets) are currently only available on Linux so
on other platforms like Solaris one still has to use SCI Transporter and this
requires a special build since it uses a special SCI Transporter.

I'm sorry, your explanation appears to contradict itself.

There is no contradiction, you can read the current doc's also to find out more about
the difference.
What is it that isn't clear?

Thank you for your bug report. This issue has been committed to our source repository of
that product and will be incorporated into the next release.

If necessary, you can access the source repository and build the latest available
version, including the bug fix. More information about accessing the source trees is
available at

Thanks, I didn't realise there was a difference between "SCI Sockets" and "SCI
Transporter".

Updated mysql-cluster-sci-sockets section of 4.1/5.0/5.1/5.2 Manuals, with references to
resolved issues and new scripts where applicable.
