[Zeitgeist] [Bug 642772] Re: WAL and event_view changes requires schema upgrade
@thekorn what is your take on this issue. Since WAL stuff has been taken out we still need your take on 2) so we can close this bug ** Changed in: zeitgeist Status: New = Confirmed -- WAL and event_view changes requires schema upgrade https://bugs.launchpad.net/bugs/642772 You received this bug notification because you are a member of Zeitgeist Framework Team, which is subscribed to Zeitgeist Framework. Status in Zeitgeist Framework: Confirmed Bug description: The recently merged changes to use journal_mode=WAL and adding some columns to event_view requires schema upgrades. 1) Setting WAL journalling *permanently* makes the DB unreadable with sqlite 3.6 which is still widely deployed. Notably if I boot back into Ubuntu Lucid Lynx Zeitgeist will no longer work as lucid only ships sqlite 3.6. 2) Contrary to what is stated in the merge request for the event_view changes the event_view VIEW is *not* regenerated on each startup. That is one of the whole points of doing schema versioning. This change makes Zeitgeist trunk unable to return any results if run on an older db. Strangely enough it doesn't raise any errors... Guys - if you are making low level changes to our DB structure like both of these changes are, please make sure you understand all the ramifications before merging. ___ Mailing list: https://launchpad.net/~zeitgeist Post to : zeitgeist@lists.launchpad.net Unsubscribe : https://launchpad.net/~zeitgeist More help : https://help.launchpad.net/ListHelp

[Zeitgeist] [Bug 642772] Re: WAL and event_view changes requires schema upgrade
Hi Mikkel, I'm sorry, number two on your list is definitely my bad. I did not know that this DROP VIEW [...] line has no effect, and I also did not test my changes on an already existing database. My changes are indeed not working as I expect them to work. I'll work on fixing the issue in bug 642803. Can't say anything to number one on your list, because I was not involved into the process of deciding about using different options, but I raised the question about using our db versioning mechanisms here.

Re: [Zeitgeist] [Bug 642772] Re: WAL and event_view changes requires schema upgrade
Hmmm I can't really figure out a good fix for this: 1) We revert the WAL change :( 2) We create a translation script that copies the DB content 1-to-1 in a new db file in case something below sqlite 3.7 is used On Sun, Sep 19, 2010 at 3:48 PM, Markus Korn thek...@gmx.de wrote: Hi Mikkel, I'm sorry, number two on your list is definitely my bad.

from what I understand people with who dual boot are confronted with this issue right?
