[Monetdb-developers] hashing algorithms usage in MonetDB/Five
by Fabian Groffen 29 Apr '06

29 Apr '06

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.

[Monetdb-developers] OpenSSL default detection
by Fabian Groffen 28 Apr '06

28 Apr '06

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.

[Monetdb-developers] meeting notes
by Niels Nes 28 Apr '06

28 Apr '06

MonetDB developers 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. Niels Nes

Could you copy the doc/Assets/AquaDataStudio.texi file and enumerate the steps. Then I will try to re-do them following the documentation.

[Monetdb-developers] Re: m 5 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/MonetDB http://www.cwi.nl/~mk/manual.pdf Comments on its structure and content are highly appreciated.

[Monetdb-developers] MonetDB seems not to list FreeBSD as a supported platform
by jau＠iki.fi 17 Apr '06

17 Apr '06

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, // jau .--- ..- -.- -.- .- .- .-.-.- ..- -.- -.- --- -. . -. / Jukka A.

[Monetdb-developers] cvs problems continue
by Niels Nes 06 Apr '06

06 Apr '06

MonetDB developers 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?
