[Monetdb-developers] New Apr2011 stable branch created
by Sjoerd Mullender 22 Mar '11

22 Mar '11

I have created new stable branches for the next feature release. This branch was created in order to stabilize the code before the feature release. From now on *only* bug fixes may go to this new stable branch. I reserve the right to undo any changes that do not comply with this rule. I also reserve the right to admit changes that are not strictly bug fixes. The name for the branch is Apr2011. So in each of your stable checkout directories you can do hg pull hg update -r to update to this new branch. Note that there is still the Mar2011 branch as well. -- Sjoerd Mullender

[Monetdb-developers] Search MonetDB Source - character processing at light speed :-)
by Arjen P. de Vries 21 Mar '11

21 Mar '11

Dear MonetDB enthusiasts, Feel free to use the suffix array search demo of the MonetDB source tree where you see fit: http://devel.spinque.com/SearchMonetDBSource/ The index is refreshed every night! You will interactively view all the exact matches of the string you type (with their count); while you type it - like Google Instant, but then per character instead of word. (Nice examples for a first try: allready, is build, != null, ...) For more complex needs, an extended syntax is supported. Here, all individual operands have to be delimited by single quotes. (Infix) operators supported are < and > for before and after, respectively, and ~ for "near". After the second operand, specify the window size in characters. Examples: '#define'<('max','min')30 finds occurrences of #define before either max or min, in a 30 character window. 'if'<'== -1'80~'&&'50 Finds 'if' appearing before '== -1' in an 80 char window, together with '&&' in a char window. We are open to suggestions (send to info(a)spinque.com to reach all of us), and keen to hear about your successful (and even the unsuccessful) uses of the demo. Many greetings, The Spinque team Arjen, Roberto and Wouter -- ==================================================================== CWI, room L333 Centre for Mathematics and Computer Science Science Park 123 Email: Arjen.de.Vries(a)cwi.nl 1098 XG Amsterdam tel: +31-(0)20-5924306 The Netherlands fax: +31-(0)20-5924199 ===================== http://www.cwi.nl/~arjen/ ====================

[Monetdb-developers] draft message
by Martin Kersten 01 Mar '11

01 Mar '11

Dear MonetDB users and developers, The preparations for the March 2011 release are on target. This release will feature a much simplified installation and compilation process using a unified bootstrap/configure/make/install. Ofcourse, installers and RPMs are also provided. Furthermore, the March 2011 release will be the freeze of the MonetDB XQuery source tree. It will remain downloadable from the website, but no active development or maintenance is foreseen. In April 2011 a MonetDB/SQL feature release will mark the split of the two code bases. From that point onward, we will primarily be concerned with SQL and its enhancements. Saying goodbye to the very old mserver4 code base, also triggered a major code renovation activity. The MonetDB/SQL code base will be cleaned from legacy code, 1-time experimental code, and all that is not strictly needed for the intended functionality. We expect that this cleanup will simplify maintenance in the future. The results of the renovation step will become visible in the fall of 2011. We plan for a smooth transition step for existing SQL environments. However, under the hood, we will change the MAL and kernel library interfaces significantly. To assess the consequences in the community we would like to learn about projects that directly address the MAL or GDK layer. Please send us an email at info(a)monetdb.org with the project highlights. regards, Martin Kersten

[Monetdb-developers] Concerning headless branch
by dsuh 15 Feb '11

15 Feb '11

I noticed a new headless branch that aims to replace BATs with COLs. Could you give me more information on COLs? Is what you are trying to achieve faster queries, less memory usage, or other advantages? Assuming that this is the new direction for MonetDB, do you expect that it will be merged with the Hg default tip for the next release after March 2011? Thanks. David Suh

[Monetdb-developers] libxml linking error during compilation, Mar2011 (Mac 10.6.6)
by Babis Nikolaou 14 Feb '11

14 Feb '11

Hi, do you have any idea about the following error: *** Warning: Linking the shared library lib_batxml.la against the loadable module *** lib_xml.so is not portable! *** Warning: lib lib_xml.so is a module, not a shared library *** And there doesn't seem to be a static archive available *** The link will probably fail, sorry Attached are the libtool's actions concerning the previous error. Furthermore, if it is relevant to my question, i provide the following information: MonetDB_Mar2011$ find . -name 'lib_xml*' ./monetdb5/extras/xml/.libs/lib_xml.la ./monetdb5/extras/xml/.libs/lib_xml.lai ./monetdb5/extras/xml/.libs/lib_xml.so ./monetdb5/extras/xml/.libs/lib_xml.so.dSYM ./monetdb5/extras/xml/.libs/lib_xml.so.dSYM/Contents/Resources/DWARF/lib_xml.so ./monetdb5/extras/xml/.libs/lib_xml_la-xml.o ./monetdb5/extras/xml/lib_xml.la ./monetdb5/extras/xml/lib_xml_la-xml.lo And last, i can assure you that there is a static library in my system for libxml (/usr/local/Cellar/libxml2/2.7.7/lib/libxml2.a) and the directory containing it has been included in the PKG_CONFIG_PATH explicitly (you can check this by inspecting the attached file). Thanks, Babis

[Monetdb-developers] Installation troubles Mac OSX 10.6.6
by Babis Nikolaou 11 Feb '11

11 Feb '11

Hi, what is going about this issue on Macs? Is there any progress? http://sourceforge.net/mailarchive/message.php?msg_id=26996821 I have managed to overcome all but the last problem concerning the AC_MSG_ERROR. The solution was to copy all .m4 files provided from the gettext package into the MonetDB build directory. Thanks, Babis

[Monetdb-developers] Installation troubles Mac OSX 10.6.6
by Jan Flokstra 02 Feb '11

02 Feb '11

Hello, I am trying to install the newest monetdb system with the single bootstrap/configure on my Mac. This does not work as good as it used to be. First when I do ./bootstrap I get the message that the libtoolize cannot be found. This is not installed on Mac OS, the default here is glibtoolize (version = 2.2.4). When using a package managers like fink libtoolize may be already installed in /sw because other packages need it. My solution was to temporary change the bootstrap file. The next problem is that it cannot find the libiconv package. I have libiconv installed in the monetdb prefix but i get the message: configure.ac:2255: error: possibly undefined macro: AM_ICONV When I remove this macro from bootstrap I get the message: configure.ac:152: error: possibly undefined macro: AC_MSG_ERROR This is a hard one because this is a standard macro, What could be wrong here?

Re: [Monetdb-developers] Packages for OSX (homebrew)
by Holger Pirk 18 Jan '11

Hi Gabriele, I actually have a small script that does that. I will talk to fabian about integrating that into the build-process. However, I don't really see it as urgent for your case. I feel that the main point of most of these package managers (darwinports, fink, homebrew, …) is that you get binaries that are optimized for your hardware. The prebuild binary obviously can't provide that anyway, so the package that is build from the sources by the package manager is way more important. kind regards holger On Jan 18, 2011, at 10:54 AM, Gabriele Modena wrote: > On Mon, Jan 17, 2011 at 10:54 PM, Holger Pirk <holger(a)airbug.de> wrote: > > Hi Holger, > >> One thing did strike me as odd in your code, though: When installing from the binary archive the absolute file names of the library dependencies are hard-coded into the mach-o binaries.

[Monetdb-developers] Packages for OSX (homebrew)
by Gabriele Modena 18 Jan '11

18 Jan '11

Hi all, over the weekend I packaged MonetDB-Oct2010-SP1 for homebrew, an increasingly popular git-based package manager for OSX. For more info about homebrew please see: http://mxcl.github.com/homebrew/ The package can be found at https://github.com/gmodena/homebrew/blob/master/Library/Formula/monetdb.rb I will be doing some more tests, tweaks and clean ups during the week, if everything works well I'd like to try to get the package included in the official repository. Please let me know if you have any comment or feedback. = Synopsis = # Install x86/x86_64 binaries $ brew install monetdb # Build from superball source $ brew install --superball monetdb = Features = - possibility to install either from binaries (x86/x86_64) or building from source (superball). Binaries are picked given the detected architecture. - plist file for (optionally) starting merovingian at boot/login = TODO = - add the possibility to build&install from the hg repository Cheers -- Gabriele
