MonetDB Mar2011 release

This is the last planned release for MonetDB4 and MonetDB/XQuery. MonetDB4 has served us well, but we need to move on. MonetDB/XQuery, being implemented on top of MonetDB4, is a casualty of this decision. The work on the Pathfinder compiler, which forms the basis of MonetDB/XQuery, continues at The University of Tübingen.

As of this "Mar2011" release (version 11.1.1), all components of MonetDB have been gathered into one single package, mainly to simplify the compilation process. If you're using the Mercurial clone, use the Mar2011 branch and the Mar2011_1 tag.

Mar 2011 feature release


Packaging

The packaging of MonetDB has been completely overhauled. In the past, there were various subpackages that had to be configured and built individually, but that had to be done in the correct order. From this release onward, the process of building MonetDB has been greatly simplified. There is only a single configuration/build/install cycle for the whole suite. On Linux/Unix systems this means one call to configure (when building from the Mercurial sources this has to be preceded by one call to the bootstrap script), one call to make, and one call to make install. On Windows, the bootstrap and configure stages can be skipped (and you need to use nmake instead of make).

The directory structure of the source tree was also completely overhauled. The MonetDB4 and MonetDB5 directories were renamed monetdb4 and monetdb5 respectively, the MonetDB directory was renamed gdk, src subdirectories were removed, and several subsystems were moved to the new common directory.

The version numbers have changed since we now have a single package. The version number of this release is 11.1.1.

Linux

We now package for Fedora 13 and 14, for Debian 5.0 (Lenny) and 6.0 (Squeeze), and for Ubuntu 9.10 (Karmic Koala), 10.04 (Lucid Lynx), and 10.10 (Maverick Meerkat).

On Debian and Ubuntu, updating to this release is a bit more involved than simply using apt-get upgrade or the "Mark All Upgrades" button in the Synaptic Package Manager. When using these commands, they will "keep back" the monetdb packages, so in order to actually update them you will need to give the apt-get install command and specify the relevant monetdb packages, or in Synaptic first select the relevant monetdb packages and then select Package->Mark for Upgrade.

Windows

Binaries are available.

Mac OS X

Binaries are available.

Solaris

Binaries are available.


MonetDB Common

  • Fixed memory detection on Darwin (Mac OS X) systems not to return bogus values
  • MonetDB/src/gdk was moved to gdk


MonetDB Server 4


MonetDB Server 5

  • sphinx module: update, adding limit/max_results support
  • Improve the performance of remote.put for BAT arguments. The put speed is now roughly equal to the speed of get on a BAT.


SQL

  • Fix bug #2648, do not allow restarting a sequence with NULL via the result of a sub-query.
  • Allow clients to release prepared handles using Xrelease commands


XQuery


Client Packages

  • Fixed bug 2677: SQL_DESC_OCTET_LENGTH should give the size in bytes required to copy the data.
  • Disable timer functionality for non-XQuery languages since it is incorrect, bug #2705
  • Added mapi_get_uri function to retrieve mapi URI for the connection
  • Allow to dump table data using INSERT INTO statements, rather than COPY INTO + CSV data using the -N/--inserts flag of mclient and msqldump. Bug #2727
  • Added support for \dn to list schemas or describe a specific one
  • Added support for \df to list functions or describe a specific one
  • Added support for \ds to list sequences or describe a specific one
  • Added support for wildcards * and ? in object names given to \d commands, such that pattern matching is possible, e.g. \d my*
  • Added support for \dS that lists also system tables
  • object names given to \d are now lowercased, unless quoted by either single or double quotes
  • Strip any trailing whitespace with the \d command


Geom Module

  • Set endianness for wkb en/decoding.


Java Module

  • PreparedStatements now free the server-side resources attached to them when closed. This implements bug #2720
