Hello, 

thank you very much. 

tests begin today. 

We also set up a testing server to run integration tests on the testing and stable versions. 

If all goes well , we should have several production server with monetdb 2015

Objet: Announcement: New Oct2014 Feature release of MonetDB suite 

The MonetDB team at CWI/MonetDB BV is pleased to announce the 
Oct2014 feature release of the MonetDB suite of programs. 

More information about MonetDB can be found on our website at 
<http://www.monetdb.org/>. 

For details on this release, please see the release notes at 
<http://www.monetdb.org/Downloads/ReleaseNotes>. 

As usual, the download location is <http://dev.monetdb.org/downloads/>. 


Important consideration when upgrading to this release. In this release 
we have fixed bug 3474. This bug made it possible that there were 
duplicates despite there being a unique or primary key constraint 
present. This could only happen for multi-column constraints. MonetDB 
maintains an internal column containing a hash for multi-column 
constraints, and there was a bug in the maintenance code of this 
column. During an upgrade, this column needs to be recreated. This is 
done by dropping and adding back the constraints. If there are no 
duplicates, adding back the constrains should work without problem, but 
if there are duplicates, adding the constraints will fail. There is 
unfortunately no easy way to tell the user, so after having made the 
first connection to the server (when the upgrade happens), check the 
merovingian log (if you use merovingian -- also known as monetdbd) or 
the server output window (if you don't use merovingian). 

Jaql support is removed. The experimental code for Jaql support has 
been removed. If you have RPM or DEB packages for Jaql installed from 
an earlier version (MonetDB-jaql and monetdb5_jaql respectively), you 
will need to uninstall them before the upgrade. 

Known issue when upgrading old versions. We have noticed that upgrading 
directly from a version older than the Jan2014 release gave an error. 
Upgrading to Jan2014 first and then on to Oct2014 should work. 

Backup. As always, make a backup of your databases before upgrading. 

Oct 2014 feature release 
MonetDB5 Server 
* Removed algebra.materialize. 
* Removed algebra.kunique and algebra.tunique. They were subsumed by 
algebra.subunique. 
* Remove algebra.antiuselect and algebra.thetauselect. They were 
subsumed by algebra.subselect. 
* Removed algebra.topN and its imlementation BATtopN. The function 
was not used. 
* Removed aggr.histogram and its implementation BAThistogram. The 
function was not used, and did not produce output in the "headless" 
(i.e. dense-headed) format. Histograms can be created as a 
by-product of group.subgroup. 

Build Environment 
* Jacqueline, the MonetDB/JAQL frontend, has been removed. The 
frontend never grew beyond being experimental, and there is no 
interest anymore to maintain the code. 

Merovingian 
* monetdb create: add -p flag to set monetdb user password on 
creation, and therefore allow creating the database in unlocked 
state 

mapilib 
* Changed mapi_timeout argument from seconds to milliseconds. 

stream 
* Changed mnstr_settimeout function so that the specified timeout is 
now in milliseconds (used to be seconds), and that it also needs an 
extra argument specifying a callback function (no arguments, int 
result) that should return TRUE if the timeout should cause the 
function to abort or continue what it was doing. 

MonetDB Common 
* Added "multifarm" capability. It is now possible to separate 
persistent and transient BATs into different directories 
(presumably on different disks). This can be done by using the 
--dbextra option of mserver5 (see the man page). 

SQL 
* Added PostgreSQL compatible string TRIM, LTRIM, RTRIM, LPAD and 
RPAD functions 
* Stop support for upgrading directly from a database created with a 
server from the Oct2012 release or older. You can upgrade via the 
Feb2013 or Jan2014 release.
