We've now published a new set of binary packages including the extended GIS functionality from the mysql-5.1-wl1326 source tree.
This release is based on the MySQL 5.1.35 code base and fixes the bugs mentioned below. It includes some improvements to the GIS functionality as well, so please use these packages for future testing of the MySQL GIS functionality.
The following GIS-related bugs were fixed in this version:
-
Bug#31753: Buffer/area functions only return first row of set -
Bug#32032: Contains() does not work on MultiPolygons, may force a disconnect and/or result in extremely long query times. -
Bug#32100: contains, intersects functions never return. Query disconnects or times out. -
Bug#33035: Intersection function returns 'Function doesn't exist' error -
Bug#40874: Buffer function doesn't work with LINESTRING -
Bug#41481: Buffer function never returns, cpu 100%, system locks up -
Bug#43493: union function returns polygon not multipolygon for non-intersecting polygons -
Bug#44753: nan error in union function
I'd like to explicitly thank John Powell for his extensive testing and bug reporting so far, he helped us quite a lot to improve the quality of the GIS code.
Please help us by by testing this new release and reporting bugs at our public bug database. For convenience, please tag your Bug reports with "gis" and make sure to put them in the "Server: GIS" category!
The Call for Papers for the OpenSQL Camp 2009 (European Edition) has ended yesterday — we received 27 excellent session proposals from various Open Source Database projects. I would like to say a big "Thank You" to everyone who submitted a talk! In the beginning I was a bit concerned that the conference would become too MySQL-centric, but this fortunately changed in the last few days.
Sadly we now have more than double the amount of sessions than we can actually host, which means that we will have to review and vote on the sessions to distill the final program. We've formed a small committee that will perform this task (currently consisting of Sheeri, Giuseppe and myself) and is in charge of finalizing the schedule. But you can help us with this! We are seeking your input on which sessions you would like to attend until Sunday, July 26th (12:00pm PST).
The system basically asks for "one vote per person per session", giving you a chance to influence the program yourself: you can cast one vote for each session by either stating you would be interested in attending it (+1) or not interested (-1). Additionally, you can add a comment for each vote to provide a reasoning for your choice. Ideally, you should of course plan to actually attend our event, but you are welcome to tell us what you would have been interested in, in case you can't make it to the Camp. See the OpenSQL Camp wiki page for more details and instructions. You can submit your votes via Twitter or the OpenSQL Camp mailing list.
We look forward to your input!
I've now posted all the current talk submissions to the OpenSQL Camp Wiki. A big Thank You to everyone who contributed so far and helped us to bang the drum for this event! If you haven't heard about OpenSQL Camp yet, it's a subconference of the Free and Open Source Conference (FrOSCon) in St. Augustin, Germany, which takes place on August 22+23. The topic of OpenSQL Camp is "Open Source databases and related technologies" and we're looking for interesting presentations in this field.
As we have 12 session slots to fill, we still have room for at least 6 more submissions! It's also a tad bit MySQL-centric at the moment, that should definitely change! We would love to get some more diversity to cover a broader range of Open Source Database technology.
So please submit your talk proposals and help spreading the word — the Call for Papers is still open until July, 19th! Post a message to relevant discussion forums and mailing lists. Know an expert in this field? Approach him directly! OpenSQL Camp Speakers will receive free entry to FrOSCon, which is worth visiting in any case!
