[Monetdb-developers] monetdb-install.sh & MAKEOPTS=-j
by Stefan Manegold 07 Apr '09

07 Apr '09

Fabian, `make -j[N] install` is know not to work (in particular with MonetDB5) due to race conditions and/or dependency issues, and there is hardly any way to fix this. Hence, setting MAKEOPTS=-j[N] before calling monetdb-install.sh might (will) result in an error during make install. I propose the following (or similar) patch to omit -j[N] when calling make install (of course, the "simpler" but maybe less desireable option is to omit MAKEOPTS completely with make install ...): Index: monetweb/Assets/monetdb-install.sh =================================================================== RCS file: /ufs/monet/repository/monetweb/Assets/monetdb-install.sh,v retrieving revision 1.42 diff -u -r1.42 monetdb-install.sh --- monetweb/Assets/monetdb-install.sh 16 Mar 2009 20:27:42 -0000 1.42 +++ monetweb/Assets/monetdb-install.sh 7 Apr 2009 09:00:33 -0000 @@ -434,7 +434,7 @@ MAKE=make fi fi - ${MAKE} ${MAKEOPTS} "$@" > $QUIET + ${MAKE} "$@" > $QUIET return $? } @@ -502,8 +502,8 @@ echo " * Processing $p" > $QUIET echo $myconf > $QUIET eval "$myconf" > $QUIET || die "configuring $p failed" - emake || die "making $p failed" - emake install || die "installing $p failed" + emake ${MAKEOPTS} || die "making $p failed" + emake $(echo "${MAKEOPTS}" | sed 's|-j *[0-9]*||g') install || die "installing $p failed" popd > /dev/null done } @@ -533,7 +533,7 @@ ${DO_XQUERY+"--with-monetdb4=included"} \ ${DO_SQL+"--with-monetdb5=included"} \ ${DEBUG} - emake || die "making $p failed" + emake ${MAKEOPTS} || die "making $p failed" done } @@ -551,7 +551,7 @@ for p in ${A} ; do cd "${S}"/$p/$(get_cvs_module $p) || die "cannot find directory $p" - emake install || die "installing $p failed" + emake $(echo "${MAKEOPTS}" | sed 's|-j *[0-9]*||g') install || die "installing $p failed" done } Stefan -- | 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 |

If we do a fetchjoin(L,R) to a table R that does not fit in memory, and the operand L has more oids then the number of pages in R then we should also sort L on the tail oids first This under the constraint that sorting L also cost some IO If you are tweaking in that area anyway, such a patch is appreciated. > > - disable vmalloc on Linux -- well actually on platforms > that do not have posix_fadvise.

[Monetdb-developers] MAL Instructions and a New Client Development
by Mohamed Saber 30 Mar '09

30 Mar '09

Hi All, I am new to MonetDB. I want to create new MonetDB commands (like the SQL) in my research project. So, I want a good reference/tutorial on the MAL instructions. After that I will do a compiler to compile my new commands to the equivalent MAL instructions. I think that the MonetDB_Manual is insufficient. If you have any reference or recommendations to achieve what I need, please let me know. I want to master the MAL language. Any help will be appreciated. Thank you so much and have a great day, Kind Regards, Mohamed Saber _________________________________________________________________ More than messages–check out the rest of the Windows Live™. http://www.microsoft.com/windows/windowslive/

Cetero senseo: never (down-)cast unless it is strictly required and you have strictly ensured/asserted that the actual value of the (larger) source type at all times fits into the range of the (smaller) target type. In fact, I made the experiences that avoiding casts as far as possible (e.g.) by consistently using the "proper" types, keeps the code much cleaner, more maintainable and less error prone, giving the compilers a chance to warn us about potential over/underflows in case we accidently assign/use non-matching types ... ;-) Stefan ps: Just sharing my experiences and lessons I learned, no "blame" at all! ;-) > The fix was suggested by Henning/JanF, and seems to at least partially fix the indexing of a 30GB XML document.

[Monetdb-developers] Fix for enable-jdbc enable-xrpcwrapper arguments of MonetDB-java
by Yue Sheng 26 Mar '09

26 Mar '09

Hi, The configure script for MonetDB-java uses the macro AC_ARG_ENABLE for its commandline arguments, but uses $withval instead of $enableval within that macro. The attached patch should fix the issue. It applies to Feb2009-SP1 bug fix release of the MonetDB suite. Thanks.

[Monetdb-developers] do_not_use_posix_fadvise
by Stefan de Konink 23 Mar '09

23 Mar '09

Hi, What is the rationale to enable or disable fadvise explicitly? do_not_use_posix_fadvise = uname(&ubuf) == 0 && strcmp(ubuf.sysname, "Linux") == 0 && strncmp(ubuf.release, "2.4", 3) <= 0; Answers as "it doesn't work" will not satisfy my hunger to this answer; because I do see a completely different performance upon manual changing this variable.
