Re: [Monetdb-developers] [Monetdb-checkins] MonetDB5/src/modules/kernel unix.mx, , 1.24, 1.25

by Sjoerd Mullender

Why do you want to be able to flush all changed files to disk? MonetDB already does flushes when they are needed for transaction support. I don't think we need to tell the kernel to synchronize any other files with the disk. This function doesn't do anything with memory management within the process. Furthermore, this function is not available on Windows.

[Monetdb-developers] Connection fails

by Riham Abdel Kader

Hi all, I have lately re-installed the Jun2008 release of MonetDB/XQuery. I can start Mserver successfully and connect to it with mclient to execute XQueries. When I try to connect to it using a MapiSocket from my java program, I get the following error: "java.net.ConnectException: Connection refused". I also tried: > telnet localhost 50000 and I get: Trying ::1... telnet: connect to address ::1: Connection refused Any idea what I could be doing wrong? Thanks for your time, Riham

[Monetdb-developers] Suggestion to ditch SHA-1, and embrace SHA-2

by Stefan de Konink

As already found in the news SHA-1 is advised to migrated off by 2010. I would suggest SHA-2 in protocol 9. Stefan

Re: [Monetdb-developers] [ monetdb-Bugs-2787825 ] mclient: stdin + statement

by Wouter Alink

The bug (#2787825) seems to be closed for comments, but I think this bug should not be closed until the documentation gets updated. typing "man mclient" on the stable branch tells me: --statement=stmt (-s stmt) Execute the specified query. The query is run before any queries from files specified on the command line are run, and before the interactive session is started (if the --interactive option is given). This is not in line with Martin's latest comment. Martin, could you re-open the bug (I don't have the permissions to do so)?
