(Archived) prepareForSave/NSSQLCore conflicts?

[freeholdhal 0]

running evernote 1.10.1 on mac os x 10.5.8

syncing with iphone 3G (running older iOS) and macbook.

noticed a few days ago that this desktop stopped synchronizing; wouldn't upload or receive

changes. if i quit evernote and restart, i see the changes upon start-up, but any in flight

changes would just sit there. had been getting a few change conflicts up to this

point (which, looking back on it may have been related).

here are the relevant /var/log messages from the latest failure:

i renamed the Library/Application Support/Evernote/data directory, forcing Evernote to create a new one

and download all of my notes, and now things seem fine....but would like to know the root cause of this

so i can avoid incurring the problem again.

I don't recall seeing that that particular error before, so I don't think it's something caused by any common actions that you did or didn't do. I.e. this seems like some sort of unexpected corruption on the database stored on disk.

We plan to release version 2.0 very soon, and you may want to try upgrading to that version when it comes out.

i was wondering if it was caused by a race condition between multiple devices syncing the same

note at the same time, with one of them failing, or a potential sync conflict between an iPhone

and an evernote instance (not sure if you're using MacOS sync services or your own to

queue the updates).

*love* evernote; it's changed the way i write, manage my work, and keep to-do lists

for my consulting business.

The full version 2.0 was released today, so you can install that.
