KMM 4.5.3, Kubuntu 11.04

Two issues:
1) KMM hangs when selecting Transaction->Go To 'Payee' menu. Always repeatable.
2) When I terminated the frozen KMM application, I found my .kmm file was truncated (file size is now 0). Luckily I had an old backup (lots of work ahead for me ). I had auto-save enabled -- if that makes any difference. I couldn't get KMM to repeat the file truncation, but in any case this is a serious bug!

So a question comes to mind, does KMM save/rename the old file before writing a new version?

The freezing (not actually a freeze, but very slow) may appear if you have a lot of payees (<1000)

The file is renamed and then saved again. If you have auto-save enabled, you may have had bad enough luck to kill the app while it was saving.

Hopefully a fix is in the works? I wish KMM would display at least a warning when enabling features with known issues.

Anyways, thanks for the quick reply.

Yes, don't kill an application when your disk is being written to. Fair enough?

Well, now I'll do that -- or better yet, will just disable the autosave.

Regarding it being "fair", isn't write-new/delete-old/rename a common technique -- especially when not using transaction-safe storage such as a database? "don't kill the app" doesn't work, say if I were to lose power while KMM is in middle of saving the file.

Just to add a bit more to the discussion: I doubt that the zero length file is caused by killing the app. If it hangs in that loop HeiKu mentioned it does not do the autosave in parallel, so you could not interrupt it during a write operation.

The trunk version of KMyMoney has a feature to keep the last n versions of the file on disk before removing it. n is a configurable parameter. This works for local files, not for files you access via protocols like http, ftp, ssh or alike (mounted filesystems via e.g. smb or nfs count as local in this context)
