[Monetdb-developers] MonetDB XQuery Module Crash
by Michael Schmidt 09 Jul '06

09 Jul '06

Hi all, I'm confused as I expected a MonetDB XQuery users mailing list instead of a developer list. However, this list was linked in the MonetDB/XQuery FAQ section so I thought it would be worth trying... Here is my problem: I'm just running some XQuery benchmarks using MonetDB together with the XQuery module. Installation was ok and I have chosen a set of queries to be evaluated against data generated with the xmlgen tool. Query processing works fine for 10MB and 50MB documents, but when processing large documents (100MB and 200MB) the client reports an error message. I even tried to figure out the source of the problem using trace option -t but do not understand the listed error messages. Here is the final error message reported by the client: ERROR: [rename]: 29 times inserted nil due to errors at tuples "pre_size", "pre_level", "pre_prop", "pre_kind", "qn_uri", "qn_prefix". ERROR: [rename]: first error was: ERROR: rename(<tmp_351>,pre_size2): operation failed ERROR: interpret_unpin: [rename] bat=171,stamp=-1285 OVERWRITTEN ERROR: BBPdecref: tmp_253 does not have pointer fixes. ERROR: interpret_params: +(param 2): evaluation error. Once again: evaluation of the same queries works fine on small streams but fails on large streams. By the way, I've installed the latest offcial release of both the server and the XQuery module. Is this a bug or are there any default memory limits causing the crash? I tried to figure out what the --set option is good for but was not able to detect any documentation on supported options.

That means, only development folks will be affected by your checkin. Users will not have your specialized flex version installed. If we indeed have problems with flex 2.5.31, I guess we'll either have to either (a) change our code such that it does compile with 2.5.31. I don't know what the problem was on Debian, so I have no clue if we could fix this. Or (b) we should check the flex version in ./configure and abort compilation in case the installed flex version is not sufficient to compile Pathfinder. Maybe you can enlighten me (maybe also others) what the actual flex problem was. I cannot find anything in the TestWeb.

[Monetdb-developers] M5 testing
by Stefan Manegold 03 Jul '06

03 Jul '06

Dear M5 developers, Currently, in the nightly testing, the cvs development trunk of the monet5 (aka. M5 or MonetDB/Five) code base is compiled and tested with the cvs development trunk ("Current") of MonetDB (v4.13) and SQL (v2.13), only. Since there is a tar-ball only alpha release of MonetDB/Five which is supposed to work with the 4.12/2.12 release of MonetDB/SQL, should the former also be tested with the latter, i.e., M5 alpha tar-ball with "Stable" M4/sql? I suppose, there is no release branch for monet5 (yet), nor has the code base for the M5 alpha tar-ball been tagged in CVS, right?

[Monetdb-developers] MonetDB 4.12.0 Release Announcement
by Fabian Groffen 23 Jun '06

23 Jun '06

It is my great pleasure to announce the availability of MonetDB 4.12.0 and its accompanying SQL 2.12.0 and XQuery 0.12.0. This release is the next step in delivering the high performance database system that has been under development for several years now. Some of the many changes since the 4.10.2 release include: MonetDB/XQuery 0.12.0 (nick-named "Ceres") Various improvments of functionality and performance. Addition of XPath extensions for XML standoff annotations. "Ceres" is a small detour on our trip to "Mars" [1], as update functionality is unfortunately still not robust enough for consumption by the majority. MonetDB/SQL 2.12.0 Many bugfixes. Support for local and global temporary tables. Preliminary support for triggers. For a complete list of new features and known problems, please see the release notes and errata list, available at: http://monetdb.cwi.nl/Development/Roadmap/Version4.12/index.html MonetDB/Five Alpha Release 1 ============================ The efforts on the next generation of MonetDB, version Five, are released now. This snapshot of version Five of MonetDB is the very first alpha release of this ongoing development. Beware: alpha is alpha! This software is only suitable as sneak-preview into the MonetDB developers team's kitchen! Come and taste some of the many delicious spices we prepare. Unlike the previous generation, Five comes with the MAL language, instead of MIL, which makes it completely incompatible with old MIL scripts. However, the SQL sources work fine with this alpha release. Comparing the performance of both backends via SQL should give you an indication of what our cooks will serve for dinner. This first alpha "appetiser" release of MonetDB/Five is nick-named "Tomato Soup". Interested users are invited to visit our MonetDB/Five page for more details: http://monetdb.cwi.nl/Development/Five/index.html Availability ============ The MonetDB family products are supported on i686, x86_64 and ia64 Linux, i686 Solaris 10, ppc and ppc64 Mac OS X 10.4 and i686 Windows XP. Binary distributions are available for Linux and Windows. The new release is available for download from our SourceForge page: http://sourceforge.net/project/showfiles.php?group_id=56967 Acknowledgements ================ Many man-hours were donated by various people to make this release happening. I want to thank al MonetDB developers for their efforts spent into this piece of software. All of our contributors and bug reporters also deserve the credits for the time they put into their contribution. Further Information =================== Further information about MonetDB, MonetDB/SQL and MonetDB/XQuery is available on our web site at: http://monetdb.cwi.nl/ http://monetdb.cwi.nl/SQL/ http://monetdb.cwi.nl/XQuery/ For details about recent changes, migration from earlier versions, and future plans, please visit our roadmap page: http://monetdb.cwi.nl/Development/Roadmap/ Developer CVS Information ========================= With every release some new tags are set and numbers changed. Please check your source trees that you use the right sticky tags on them. The sources that are put in this release are tagged as follows: MonetDB MonetDB_4-12-0 sql SQL_2-12-0 pathfinder XQuery_0-12-0 The new stable branches are now available through the following tags: MonetDB MonetDB_4-12 sql SQL_2-12 pathfinder XQuery_0-12 To update to the new stable branches use ``cvs update -r <branch tag>`` for the repositories you work with. Bugs versus Features -------------------- All bugfixes to the code base should be committed to the respective stable branches. All changes made in the stable branches are semi-automanically propagated to the respective development trunks. To ease the task of the propagators, please don't propagate fixes yourself, unless you know how to do it appropriately and have an explicit agreement from one of the propagators. All new features should be checked in into the respective development trunks. [1] See http://en.wikipedia.org/wiki/1_Ceres and http://www.nasa.gov/multimedia/imagegallery/image_feature_404.html

[Monetdb-developers] (Almost) ready to release "Ceres"
by Stefan Manegold 22 Jun '06

22 Jun '06

Dear all, finally, we are (almost) ready to release the new versions MonetDB 4.12.0 MonetDB/SQL 2.12.0 MonetDB/XQuery 0.12.0 also nicknamed "Ceres" --- a small detour on our trip to Mars (cf. http://en.wikipedia.org/wiki/1_Ceres http://www.nasa.gov/multimedia/imagegallery/image_feature_404.html ) "Almost" means that all source are "stable" and all packages are built. The latter are (temporarily) available from http://monetdb.cwi.nl/testing/projects/monetdb/Stable/.DailyBuilds.MonetDB_… The respective CVS versions are tagged as "MonetDB_4-12-0" "SQL_2-12-0" "XQuery_0-12-0" Please do not touch these tags. Propagation of future bug fixes from the release branches to the development trunk will be suspended until Sjoerd and me are back from our trip at te beginning of July. What's missing is to upload all this to SF (those at CWI will find all files incl. the usual release notes and chang logs in /net/corona.ins.cwi.nl/export/scratch0/manegold/MonetDB_4-12-0/ ). Further, the web site has to be updated and the release needs to be announced (a template for the announce mail is in /net/corona.ins.cwi.nl/export/scratch0/manegold/MonetDB_4-12-0/AnnounceMail-4.12.0 ). Since I have to catch my plane to Chicago tomorrow morning, I'll leave these tasks trustfully to you. Stefan ps: As you might have noticed, I'm only talking about the M4 related release. I was not aware that the M5 alpha source-tarball-only release was planned to happen together with the M4 release; I thought they only "by chance" happened to happen at about the same time... I agree with Fabian, that the M5 alpha source-tarball-only release should indeed be based on the M4 [421].12.0 release(s), but I had no time to take care of that and/or to shift M5 testing from the "Current" to the "Stable" branch. But since the M4 [421].12.0 release(s) are now ready, please feel free to use them to build the M5 alpha source-tarball-only release ;-) -- | Dr. Stefan Manegold | mailto:Stefan.Manegold@cwi.nl | | CWI, P.O.Box 94079 | http://www.cwi.nl/~manegold/ | | 1090 GB Amsterdam | Tel.: +31 (20) 592-4212 | | The Netherlands | Fax : +31 (20) 592-4312 |

[Monetdb-developers] We're green!
by Stefan Manegold 22 Jun '06

22 Jun '06

Dear all, appart from some minor platform-dependent issues --- some scattered failing test with MonetDB, no Java/ant on the SuSE machine in Konstanz, (yet) lacking/incomplete locale/utf-8 support on our Solaris 10/x86 machine, (most probably) flex/bison-releated XQuery parser problems on Debian, no (utf-8 enabled) PCRE on SuSE and Solaris 10/x86, failing (hanging) `make install` on CygWin --- our TestWeb gives us an "all green" for the release: http://monetdb.cwi.nl/Development/TestWeb/Stable/ or directly http://monetdb.cwi.nl/testing/projects/monetdb/Stable/MonetDB/.mTests103/in… http://monetdb.cwi.nl/testing/projects/monetdb/Stable/sql/.mTests103/index_… http://monetdb.cwi.nl/testing/projects/monetdb/Stable/pathfinder/.mTests103… Thank you all very much for your hard and focused work! Wrt. the TestWeb, this is probably the cleanest ("greenest") state we've had so far! Hence, I strongly propose that we use the respective code base (tagged as "MonetDB_4-12-0", "SQL_2-12-0", "XQuery_0-12-0", respectively, in CVS) for the release. Any future changes should/will then go into the next (bug-fix?) release. I also saved last nights daily built packages to be used for the release. They're available at http://monetdb.cwi.nl/testing/projects/monetdb/Stable/.DailyBuilds.MonetDB_… To do/finish the release, we should check and update the MonetDB web site http://monetdb.cwi.nl/ and prepare some release notes. Any help (also from outside CWI, e.g., with checking the web site) is more than welcome! For Sjoerd: The code base of your last-night's Windows builds is tagged as "{MonetDB_4,SQL_2,XQuery_0}-12-0_win". Would it be possible to make new builds from the latest "{MonetDB_4,SQL_2,XQuery_0}-12-0" code base? Once again, thank you all very much, and let's continue working on this great project!

[Monetdb-developers] overflow checks in the Pathfinder shredder?
by Stefan Manegold 21 Jun '06

21 Jun '06

Jan F. (and/or others), did I understand you correctly on Tuesday that there are checks in the pathfinder shredder (XQuery_0-12 release branch) that detect overflows in case of huge documents, i.e., level > GDK_chr_max size > GDK_int_max OIDs > GDK_oid_max and generate the respective errors? If not, shouldn't we add them, and trigger a proper error in case they occur? The same question arises also for (intermediate) results during query processing...
