[Monetdb-developers] Physical stack space
by Maurice van Keulen 12 Nov '07

12 Nov '07

Hi, When writing recursive xqueries that that manipulate somewhat larger documents, MonetDB frequently quits with the error message !ERROR: interpret: running out of physical stack space! Is there a way to increase the physical stack space? I found no parameter to set in MonetDB.conf, perhaps in the source somewhere?

[Monetdb-developers] MAPI wire protocol?
by Tim Gebhardt 07 Nov '07

07 Nov '07

Hello, I'm working on a C#/.NET client library to connect to a MonetDB server. I've mapped most of the libMapi.dll api calls so that I can call the C library from .NET but this presents a few problems: 1. There's a performance penalty to interface native code libraries to .NET 2. There's a lot of overhead of marshaling UTF8 strings between .NET and the C library, and potential problems with NULL parameters. 3. There's a portability problem with using the native libraries (trouble deploying to the Mono runtime) I think the client library would be better off implementing the MAPI wire protocol rather than interfacing with the C library, but I cannot find any documents that detail the protocol. Is there somewhere this is published, or did I just not Google the right stuff? Also if anyone is interested in giving me a hand you can find the Google Code workspace of the aforementioned project at this link: http://code.google.com/p/monetdb-net/ -Tim Gebhardt tim(a)gebhardtcomputing.com

Why don't you just drop the whole build_compiler variable you introduced, and use the completely transparent and well supported and usually expected build.compiler variable only once you really want to control what compiler is being used, as I suggested to you earlier?

Isn't the default good enough? Won't still this require Sun Java (since you mentioned you tried it with value gcj to compile using gcj)? If so, then that isn't good enough. -- Sjoerd Mullender

Just rely on standard behaviour, and set build.compiler in your build.properties to gcj if you want to build with gcj.
