Shouldn't this also be done on the stable branch?

Hence, IMHO (1) "-G" / "-g" and "\G" / "\g" make only sense as pairs, i.e., to switch back and forth, i.e., removing one does not make (much) sense; and (2) XQuery still requires both for the time being. Thus, if we don't need either for SQL any more, we should remove the documentation (and functionality) of both switches only for SQL, but not for XQuery --- and if we do so, we should do this everywhere, i.e., not only with mclient, but also with Mserver/mserver5, MonetDB.conf/monetdb5.conf, Mtest.py and the wbe site --- well, lacking branches, the latter can only be done once we have a new feature release in about 3 month from now ...

[Monetdb-developers] New "testing" CVS module
by Stefan Manegold 12 Dec '08

12 Dec '08

Dear fellow MonetDB developers, I just separated the MonetDB testing tools (Mtest.py & friends) from MonetDB/src/testing/ into their own "testing" CVS module / MonetDB component. IMPORTANT NOTE: =============== In case you plan to upgrade your exiting CVS-based "MonetDB" installation, please run `make uninstall` in your "MonetDB" build directory, first, i.e., before running `cvs update` in your "MonetDB" source directory. Once you update your "MonetDB" to the latest CVS development trunk version, and plan to continue (or start) using Mtest.py, you also need to check out the new "testing" CVS module (from SF) and compile and install it any time after you compiled and installed "MonetDB", and before you plan to use Mtest.py. The new "testing" CVS module depends only on "MonetDB" (and hence requires that to be installed), but on no other MonetDB component (except from the "buildtools", in case your are compiling from CVS sources). No other MonetDB component depends on the new "testing" CVS module other than that you obviously need to have "testing" installed once you want/need to run tests using Mtest.py. Details: -------- The MonetDB testing tools (Mtest.py & friends) are not part of the actual MonetDB functionality, but mainly for MonetDB development purpose (and hence only distributed only in the source tarballs, but not in any (official) binary packages). To make them less dependent on release cycles (and vice versa), and well as to prepare making them usable without MonetDB --- for now, they actually still depend on MonetDB; see below) --- we decided to separate the MonetDB testing tools from the "MonetDB" CVS module into their own "testing" CVS module. For the time being (i.e., until further notice), "testing" depends on "MonetDB" --- more precisely only on some utils from MonetDB/src/common/, but not on the GDK kernel from MonetDB/src/gdk/, as (1) Mtest.py (mainly for "convenience") still uses monet_options.py; and (2) (on Windows only), Mdiff.c uses "our" getopt code. Python modules "subprocess26.py" & "trace.py" have been moved from <PYTHON_LIBDIR>/MonetDB to <PYTHON_LIBDIR>/MonetDBtesting . Changes are wrapped in CVS tags "before_testing_separation" & "after_testing_separation".

Can you have a 1-2 hour look at gridsql if it is feasible at all. If so, let's push Venks.... ;) otherwise avoid the frustration for him.

[Monetdb-developers] Size limits for DECIMAL(P,S)
by Schwarz, Omri 05 Dec '08

05 Dec '08

Hi, all. I managed to build MonetDB and am looking through it right now, but I am hitting against rgw 18 digit size limit for the decimal type. How hard would it be to reimplement it on the back end to make room for more digits?
