Henning, thanks for being aware of stable output and maitaining int accoring to your changes. However, did you change the signatures of PROCs client(), descendant(), descendant_or_self(), ll_child(), ll_descendant(), ll_descendant_or_self(), preceding(), preceding_sibling() in addition to vx_maintain()? I cannot see any comment in your checkin message, nor did I find any hint in the diffs. Hence, why did you change the respective stable output, then? Well, to solve the "riddle" (addressing all of you, not only Henning!): when updating stable output, please make sure that (1) either your code base is indeed up-to-date, or that (2) you change only those parts of stable output which actually relate to your code changes. Stable output is even more important and sensitive than the actual code --- it is used to test the correctness of the actual code. Hence, please treat it with the respective concentration and care. Thanks.

I am using monetBD5 with datacell module and I got the following crash. I know it is related with memory map and maybe a valgrind execution would be a nice thing to do. However, I would like more feedback from the experts: insert 1188567930287233: line :[0,3] /ufs/goncalve/scratch/MonetDB/MonetDB5/lib/libmal.so.0[0x2aaaaaace64f] /ufs/goncalve/scratch/MonetDB/MonetDB5/lib/libmal.so.0(reenterMAL+0x7a)[0x2aaaaaac94d5] /ufs/goncalve/scratch/MonetDB/MonetDB5/lib/MonetDB5/lib/lib_datacell.so[0x2aaabccb2207] /lib64/libpthread.so.0[0x33dba062f7] /lib64/libc.so.6(clone+0x6d)[0x33daace86d] ======= Memory map: ======== 00400000-00405000 r-xp 00000000 08:13 9634823 /net/amelia/export/scratch1/goncalve/MonetDB/MonetDB5/bin/mserver5 00604000-00605000 rw-p 00004000 08:13 9634823 /net/amelia/export/scratch1/goncalve/MonetDB/MonetDB5/bin/mserver5 00605000-00d4e000 rw-p 00605000 00:00 0 [heap] 40000000-40001000 ---p 40000000 00:00 0 40001000-40801000 rw-p 40001000 00:00 0 40801000-40802000 ---p 40801000 00:00 0 40802000-41002000 rw-p 40802000 00:00 0 41002000-41003000 ---p 41002000 00:00 0 41003000-41803000 rw-p 41003000 00:00 0 41803000-41804000 ---p 41803000 00:00 0 41804000-42004000 rw-p 41804000 00:00 0 42004000-42005000 ---p 42004000 00:00 0 42005000-42805000 rw-p 42005000 00:00 0 42805000-42806000 ---p 42805000 00:00 0 42806000-43006000 rw-p 42806000 00:00 0 43006000-43007000 ---p 43006000 00:00 0 43007000-43807000 rw-p 43007000 00:00 0 33da600000-33da61a000 r-xp 00000000 08:15 2578621 /lib64/ld-2.5.so 33da819000-33da81a000 r--p 00019000 08:15 2578621 /lib64/ld-2.5.so 33da81a000-33da81b000 rw-p 0001a000 08:15 2578621 /lib64/ld-2.5.so 33daa00000-33dab46000 r-xp 00000000 08:15 2578761 /lib64/libc-2.5.so 33dab46000-33dad46000 ---p 00146000 08:15 2578761 /lib64/libc-2.5.so 33dad46000-33dad4a000 r--p 00146000 08:15 2578761 /lib64/libc-2.5.so 33dad4a000-33dad4b000 rw-p 0014a000 08:15 2578761 /lib64/libc-2.5.so 33dad4b000-33dad50000 rw-p 33dad4b000 00:00 0 33dae00000-33dae82000 r-xp 00000000 08:15 2578841 /lib64/libm-2.5.so 33dae82000-33db081000 ---p 00082000 08:15 2578841 /lib64/libm-2.5.so 33db081000-33db082000 r--p 00081000 08:15 2578841 /lib64/libm-2.5.so 33db082000-33db083000 rw-p 00082000 08:15 2578841 /lib64/libm-2.5.so 33db200000-33db202000 r-xp 00000000 08:15 2578887 /lib64/libdl-2.5.so 33db202000-33db402000 ---p 00002000 08:15 2578887 /lib64/libdl-2.5.so 33db402000-33db403000 r--p 00002000 08:15 2578887 /lib64/libdl-2.5.so 33db403000-33db404000 rw-p 00003000 08:15 2578887 /lib64/libdl-2.5.so 33db600000-33db614000 r-xp 00000000 08:15 4234966 /usr/lib64/libz.so.1.2.3 33db614000-33db813000 ---p 00014000 08:15 4234966 /usr/lib64/libz.so.1.2.3 33db813000-33db814000 rw-p 00013000 08:15 4234966 /usr/lib64/libz.so.1.2.3 33dba00000-33dba15000 r-xp 00000000 08:15 2578924 /lib64/libpthread-2.5.so 33dba15000-33dbc14000 ---p 00015000 08:15 2578924 /lib64/libpthread-2.5.so 33dbc14000-33dbc15000 r--p 00014000 08:15 2578924 /lib64/libpthread-2.5.so 33dbc15000-33dbc16000 rw-p 00015000 08:15 2578924 /lib64/libpthread-2.5.so 33dbc16000-33dbc1a000 rw-p 33dbc16000 00:00 0 33dce00000-33dce35000 r-xp 00000000 08:15 4225510 /usr/lib64/libreadline.so.5.1 33dce35000-33dd034000 ---p 00035000 08:15 4225510 /usr/lib64/libreadline.so.5.1 33dd034000-33dd03c000 rw-p 00034000 08:15 4225510 /usr/lib64/libreadline.so.5.1 33dd03c000-33dd03d000 rw-p 33dd03c000 00:00 0 33de200000-33de203000 r-xp 00000000 08:15 2578939 /lib64/libtermcap.so.2.0.8 33de203000-33de402000 ---p 00003000 08:15 2578939 /lib64/libtermcap.so.2.0.8 33de402000-33de403000 rw-p 00002000 08 Program received signal SIGABRT, Aborted.

[Monetdb-developers] Release plans
by Sjoerd Mullender 29 Aug '07

29 Aug '07

We are planning to start a new "Stable" branch in about one to two weeks time in preparation for a new release. This new release will consist of all packages. I would like to ask all developers to be conservative with your checkins until that time. This does not mean you're not allowed to check in any fixes or new features, just that I would like to urge you to make extra sure that your changes work. Also, by checking in any changes before we create this new branch, you commit yourself to making sure that the features work flawlessly in two weeks' time. This new release will not contain many new features. It is mostly a bug-fix release with some new stuff. We wanted to do a partial release, but can't because of slight incompatibilities between the current Development and Stable branches, so we need to release either nothing or everything. We've chosen everything. By the way, this is independent from the SQL bug fix release which is going to be released today (and hence will be superseded in a few weeks time). -- Sjoerd Mullender

Re: [Monetdb-developers] C-Store as MySQL storage engine
by Daniel J Abadi 25 Aug '07

25 Aug '07

Hi Dossy, There is no source repository/patch submission system in C-Store like you'd see in a mature open source community project. C-Store is only designed to be used as tool by academic researchers to look at the properties of column-oriented database query execution. It is far from a complete database system and parts of the code are quite rudimentary. Further, it has been neglected recently as many of the people who used to code for C-Store are now coding for Vertica. However, I like the idea of using a column-oriented database as a storage engine for MySQL. The thought actually crossed my mind as well recently when I read about Solid using their database as a storage engine for MySQL. My recommendation is that you look into the Monet instead of C-Store, however (http://monetdb.cwi.nl/) They have a far more complete open source column-oriented database. BTW: I came across your blog entry on Vertica recently. IMO, Vertica is much more than Sybase IQ, with far more advanced compression schemes, and the query executer is better able to take advantage of the column-oriented layout (data is kept in columns as long as possible and operated on as such). I think Vertica is about 10 times as fast as IQ. Your blog entry says you have been in contact recently with the director of sales at Vertica who can probably give you more information.
