|This is the first release of the MonetDB suite that does not contain MonetDB4 and MonetDB/XQuery. As already mentioned in the Mar2011 release notes, work on the Pathfinder compiler, which forms the basis of MonetDB/XQuery, continues at The University of Tübingen.
An upgrade from the Mar2011 release should be smooth, even if MonetDB/XQuery is installed. The Windows installers for MonetDB/SQL and MonetDB/XQuery have always been independent, and the Fedora, Debian, and Ubuntu versions have been made independent in the Mar2011 release.
The Apr2011 release uses a slightly changed SQL catalog than previous releases. The catalog will be updated automatically the first time an SQL database is opened. Note that because of the incompatibility, once updated, the database cannot be read by older versions. Also note that a database from the Feb2010 release or before cannot be read by this release. First update the database with the Mar2011 release.
This is also the first release where we have created FreeBSD binaries. These binaries are highly experimental. The software should run as well as on any other system, but the packaging is obviously different from other systems. As before, we also provide binaries for Windows, Fedora (13 and 14), Debian (5.0 and 6.0), Ubuntu (9.10, 10.04, and 10.10), Mac OS X, and Solaris.
Apr 2011 feature release
Plugged a small memory leak occurring upon redirects by the server (e.g. via monetdbd)
|MonetDB Common||Fixed bugs in antiselect which gave the incorrect result when upper and lower bound were equal. This bug could be triggered by the SQL query SELECT * FROM t WHERE x NOT BETWEEN y AND y|
|Java Module||Clarify exception messages for unsupported methods
Removed XQuery related XRPC wrapper and XML:DB code, removed support for language=xquery and language=mil from JDBC.
||Mserver5 no longer reads monetdb5.conf upon startup by default. Use --config=file to have mserver5 read a configuration on startup|
|SQL||Some names in the SQL catalog were changed. This means that the database in the Apr2011 release is not compatible with pre-Apr2011 databases. The database is converted automatically when opened the first time. This database can then no longer be read by an older release.|
|Merovingian||Fix monetdb return code upon failure to start/stop a database.
The forward property for databases has been removed. Instead, only a global proxy or redirect mode can be set using monetdbd.
Monetdbd can no longer log error and normal messages to separate logfiles, logging to stdout and stderr is no longer possible either.
The .merovingian_pass file is no longer in use, and replaced by the .merovingian_properties file. Use monetdbd (get|set) passphrase to view/edit the control passphrase. Existing .merovingian_pass files will automatically be migrated upon startup of monetdbd.
Monetdbd now understands commands that allow to create, start, stop, get and set properties on a given dbfarm. This behaviour is intended as primary way to start a MonetDB Database Server, on a given location of choice. monetdbd get and set are the replacement of editing the monetdb5.conf file (which is no longer in use as of the Apr2011 release). See monetdbd(1).
