Hi all, FYI
Sourceforge isn't really cooperating, but I implemented MD5 and SHA1
hash algorithms support during challenge response in MAPI. I extended
the JDBC driver to be able to use SHA1 or MD5 next to plain (crypt is
not easily available in Java). I will check in my changes as soon as
1) SourceForge lets me, and
2) My physical state + location lets me
I also added a little option to JdbcClient to force usage of a specified
hash algorithm, using -Xhash. I conducted a little experiment to see
the effect of connecting with a hash or plain. The results for my system is as follows: (I ran every call 10 times and took the average)
% time java -jar jars/jdbcclient-1.4.jar -Xhash SHA1 < /dev/null
real 0.29
% time java -jar jars/jdbcclient-1.4.jar -Xhash MD5 < /dev/null
real 0.29
% time java -jar jars/jdbcclient-1.4.jar -Xhash plain < /dev/null
real 0.23
The precision of time is seconds here, so the difference in time (or the
cost of both hash implementations) is 0.06 seconds. This includes the
time for the server to do the same of course. All in all, not really
shocking IMHO. Please note that the JdbcClient does a lot of other
stuff like querying the database for its version number and such. When
not doing that the time will be probably lower. Also, the wallclock
time does also include the full JVM startup. The C implementation of
the hashes might be more efficient, I can only tell something useful
about that once MapiClient will also support hash algorithms.
In conf/monet.m4 openssl detection is currently set to default to "no".
Since I want to make use of the SHA1 and MD5 hashes from openssl and
think that this should be enabled by default, I was wondering if there
are objections agains setting "have_openssl=auto", such that
auto-detection is done, and OpenSSL will be used whenever available.
If I see no objections within a few days, I will assume it is ok to make
this change to conf/monet.m4.

Today another MonetDB Meeting was held at the CWI. In this meeting we
decided to aim for another MonetDB{SQL/XQuery} release on June 25.
To reach this goal we are going for a Feature freeze (ie the usual release
candidates and release branch) on June 1. So if you have any (well tested)
interesting features too add please commit them before June 1.
The we are aiming for an Release with many new features. See
http://monetdb.cwi.nl/Development/Roadmap/index.html for full details.
Among these features are hopefully 'Xquery updates' and 'SQL triggers'.
Before this MonetDB 4 release we are going for an alpha release via a
'tarball' of the MonetDB 5 development on May 05. This will be the first
public release of the MonetDB 5 code base.

Ok, downloading requires your credentials to be left behind and
some hints what to fill in where. Could you copy the
doc/Assets/AquaDataStudio.texi file and enumerate the steps.
Then I will try to re-do them following the documentation.
Niels,
The documentation for M5 is self-contained. The overlapping pieces
(e.g. HowToInstall's) are hand synchronized. The GDK and module layers
are not touched.
I will go through the Website and identify pieces to be shared.
The latest draft versions are available at:
http://www.cwi.nl/~mk/MonetDBhttp://www.cwi.nl/~mk/manual.pdf
Comments on its structure and content are highly appreciated.

Today the MonetDB website got its new logos. This of cause is just improves
the way the site looks. So if you have improvements for the content we
are pleased too add it.

Hello,
As the subject says MonetDB web site does not list FreeBSD as
a supported platform for MonetDB. Neither was I able to find
MonetDB in the FreeBSD ports tree (/usr/ports/databases).
Is there some portability issue which prevents that or is it
only due to lack of time and/or resources?
Cheers,

Sourceforge cvs has serious problems (my guess is their raid system is
broken and no spare is available). This (again) raises the question if
sourceforge is the appropriate place for our cvs repository.
Does anybody have better experiences with other sites like sourceforge?
