[Monetdb-developers] radix.mx signed/unsigned issue?
by Fabian Groffen 17 Jun '06

17 Jun '06

I just tried to compile MonetDB 4 and hit a compiler warning (error) in radix.mx on a signed/unsigned comparison. I applied the attached patch to make it compiling again, but I'm not sure if this is the intention, as the hard cast might result in the wrong result perhaps? Also, am I the only one experiencing this problem?

[Please use the MonetDB-developers mailing list (monetdb-developers(a)lists.sourceforge.net) for this kind of discussions, and make sure you're subscribed to it (with your current email address). Thanks!] I suggest to not checkin any changes to the XQuery_0-10 stable branch of pathfinder, but to wait until we (Niels, Sjoerd, me) create the new XQuery_0-12 stable branch (together with the new MonetDB_4-12 & SQL_2-12 release branches) early next week. Of course, you're free and welcome to try to compile pathfinder's stable branch (XQuery_0-10) with the current MonetDB 4.11 development trunk to sort-out the problems and start fixing them off-line. The short-term "feature-freeze" for the "intermediate release" applied only to MonetDB & sql; as Peter explained, for pathfinder we plan only porting of XQuery_0-10 to comply/compile with MonetDB 4.11 as well as applying bugfixes (including back-porting bug fixes from XQuery 0.11 as far as necessary/possible).

Forgot to answer my question: The problem with the stack that was too small has been fixed. The StandOff-joins now increase the stack-size whenever it grows out-of-bound. The StandOff-axes in the stable branch still have two bugs to fix that I know of: - sorting of the final result (with multiple iters, the result is not sorted at the moment). The current work-around is adding a self-step directly after the StandOff-step. - David Ahn mentioned another bug, when nesting 3 for-loops, each using the select-narrow-axis the output is garbage, but I don't know whether this bug is related to the sorting, or perhaps to another part of MonetDB/XQuery. Still have to figure this out.

[Monetdb-developers] pathfinder release: bugfixing opportunity
by Peter Boncz 07 Jun '06

07 Jun '06

LS, Today we had a MonetDB meeting about the release. We decided to have a release now, but without Pathfinder. For the Pathfinder release with updates, multi-documents and soap the realistic time-frame becomes *september* (well, maybe maybe august), but there will be a feature freeze around SIGMOD (june 25). We anticipate a long testing and debugging stage. Sorry, but this is reality. No SIGMOD release. As MonetDB/SQL and the alpha Monet5 do not want to wait any longer just to roll through the accumulated new features and fixes, there is also an imminent release. As we release always all components to keep compatability and the test web easily manageble in a single Stable an single Current branch, the new release will include the *stable* branch of pathfinder. There will be a (very) small porting effort to make stable-pathfinder work on head-monet. However, one of the tasks ahead for a pathfinder release anyway is bug-fixing. Thus, we can take this opportunity to identify quick-win bugs in pathfinder and release those. We can also look at the bugs fixed in pathfinder in the past period, and ask ourselfves whether rollling them through is useful and little work. I guess the freeze for the direct release is only within days, and I recommend you all not to spend much time on it. At least the new pathfinder will contain the BATuselect fix in the serialization (admittedly not as fast as Jan R.'s current implementation but still better than before). As the experiences with it have been positive, I propose this time to build pathfinder with burkowski enabled. Thus we can point the guy who wants windows with burkowski (and other like him) to the new binary release. Note that the functionality is by default still disabled; you need to set a configuration switch to yes to turn it on. Peter

[Monetdb-developers] MonetDB release meeting

MonetDB developers On wednessday morning (june 7) from 10:00 till 12:00 we will have another MonetDB meeting. Reason we missed our target freeze date and therefor will miss the release date of end of june. So we should reset those dates, assess the tasks at hand and possibly resuffle some of the work.

[Monetdb-developers] feature freeze
by Peter Boncz 05 Jun '06

05 Jun '06

Niels, Feature freeze? One little problem: none of the XQuery targets is met (updates, soap, multi-document). So what do you (or you talk about "we") want to release? In my opinion - but correct me if I'm wrong - the goal of the release is the new XQuery version that brings updates. Thus I am against a feature freeze on monday. Creating the branch now will just create propagation overhead. It will take al least another 3 weeks until the basic features will be implemented, after that we have to go into a testing and packaging period still. Of course one should try to impose limits and milestones. Or even scrap goals if the milestones are never made. But in this case there is clear progress being made. Peter

[Monetdb-developers] monetdb feature freeze
by Niels Nes 02 Jun '06

02 Jun '06

MonetDB developers As you probably all know last thursday june 1 was the planned feature freeze date. Because of many reasons we didn't directly create the seperate cvs branches to really enforce the freeze. But we are serious, so we are about create these branches soon. Current planning is to create these on tuesday morning. Afcouse during the branch creation its better not to checkin changes. Therefor I hope everybody cleans up its checkout versions and checks in those changes which should end up in the to be released version before monday evening. The version of monday night (amsterdam time) marks, which features will be in the release.
